<p>When overriding the MembershipProvider and calling it directly, is there a way to fill the NameValueCollection config parameter of the Initialize method without manually looking through the config file for the settings? </p>
<p>Obviously this Initialize is being called by asp.net and the config is being filled somewhere. I have implemented my own MembershipProvider and it works fine through the build in controls.
I would like to create a new instance of my provider and make a call to it directly, but I don't really want to parse the .config for the MembershipProvider, it's connection string name and then the connection string if it's already being done somewhere.</p>

<p>From everything I've read, it seemed that adding paging to a ListView control should be dead simple, but it's not working for me. After adding the ListView and DataPager controls to the form and wiring them together, I'm getting very odd behavior. The DataPager correctly limits the ListView's page size, but clicking the paging buttons doesn't affect the ListView at all. The paging buttons seem to think they are doing they're job, as the last button is disabled when you go to the last page, etc., but the ListView never changes. Also, it takes two clicks on the DataPager to get it to do anything, i.e., clicking on Last once does nothing, but clicking it a second time causes the DataPager to react as if the last page is now selected.</p>
<p>The only thing I can think of is that I'm binding the DataSource at runtime (to a LINQ object), not using a LinqDataSource control or anything. Has anyone seen this behavior? Am I doing something wrong? Here's the code I'm using:</p>
<pre><code><asp:DataPager ID="HistoryDataPager" runat="server" PagedControlID="HistoryListView" PageSize="10">
<Fields>
<asp:NextPreviousPagerField ButtonType="Button" ShowFirstPageButton="true" ShowLastPageButton="true" />
</Fields>
</asp:DataPager>
<asp:ListView ID="HistoryListView" runat="server">
...
</asp:ListView>
</code></pre>
<p>In the code-behind:</p>
<pre><code>Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
HistoryListView.DataSource = From x in myContext.myTables ...
DataBind()
End If
End Sub
</code></pre>

<p>I have to create a site definition for a client that must contain pre-defined web part pages. I can create the web part pages but am at a loss when it comes to attaching them to the site on creation.</p>
<p>I know web part pages created through SharePoint are stored in a Document Library. Do I need to pre-populate a "Web Part Pages" document library and add the needed navigation to these files? If so, how do I go about adding the needed aspx files?</p>
<p>Finally, are there any caveats that I should be aware of for configuring the custom web part page in onet?</p>

<p>What tweaks / addins / themes do you have rigged up to make your IDE awesome? For example, in Visual Studio I <a href="http://www.hanselman.com/blog/VisualStudioProgrammerThemesGallery.aspx" rel="nofollow noreferrer">color themes</a>, <a href="http://www.devexpress.com/Products/Visual_Studio_Add-in/Coding_Assistance/" rel="nofollow noreferrer">CodeRush</a> draws lines between braces, I always install and use the <a href="http://www.microsoft.com/downloads/details.aspx?familyid=22e69ae4-7e40-4807-8a86-b3d36fab68d3&displaylang=en" rel="nofollow noreferrer">Consolas</a> font and I have it setup to <a href="http://blogs.msdn.com/saraford/archive/2008/06/30/did-you-know-you-can-use-team-settings-to-keep-visual-studio-settings-on-different-machines-in-sync-248.aspx" rel="nofollow noreferrer">sync my settings across computers</a> for when I change hotkeys and whatnot with the help of <a href="https://www.foldershare.com/welcome.aspx" rel="nofollow noreferrer">FolderShare</a>.</p>
<p>Also, this isn't Visual Studio specific, please feel free to mention what you do with Emacs or Eclipse or whatnot as many of us use a few.</p>

<p>I am displaying a texture that I want to manipulate without out affecting the image data. I want to be able to clamp the texel values so that anything below the lower value becomes 0, anything above the upper value becomes 0, and anything between is linearly mapped from 0 to 1. </p>
<p>Originally, to display my image I was using glDrawPixels. And to solve the problem above I would create a color map using glPixelMap. This worked beautifully. However, for performance reasons I have begun using textures to display my image. The glPixelMap approach no longer seems to work. Well that approach may work but I was unable to get it working. </p>
<p>I then tried using glPixelTransfer to set scales and bias'. This seemed to have some sort of effect (not necessarily the desired) on first pass, but when the upper and lower constraints were changed no effect was visible. </p>
<p>I was then told that fragment shaders would work. But after a call to glGetString(GL_EXTENSIONS), I found that GL_ARB_fragment_shader was not supported. Plus, a call to glCreateShaderObjectARB cause a nullreferenceexception.</p>
<p>So now I am at a loss. What should I do? Please Help.</p>
<hr>
<p>What ever might work I am willing to try. The vendor is Intel and the renderer is Intel 945G. I am unfortunately confined to a graphics card that is integrated on the motherboard, and only has gl 1.4.</p>
<p>Thanks for your response thus far.</p>

<p>I'm new to Windows programming and after reading the Petzold book I wonder: </p>
<p>is it still good practice to use the <code>TCHAR</code> type and the <code>_T()</code> function to declare strings or if I should just use the <code>wchar_t</code> and <code>L""</code> strings in new code?</p>
<p>I will target only Windows 2000 and up and my code will be <a href="http://en.wikipedia.org/wiki/Internationalization_and_localization" rel="noreferrer">i18n</a> from the start up.</p>

<p>I'm trying to make a simple blackjack program. Sadly, I'm having problems right off the bat with generating a deck of cards.</p>
<pre><code>#include <iostream>
#include <vector>
using namespace std;
int main() {
vector<char> deck;
char suit[] = {'h','d','c','s'};
char card[] = {'2','3','4','5','6','7','8','9','10','J','Q','K','A'};
for (int j=0; j<13; j++) {
for (int i=0; i<4; i++) {
deck.push_back(card[j] suit[i]);
}
}
return 0;
}
</code></pre>
<p>I know my problem begins with me trying to assign the value '10' to a char. Obviously I couldn't get this to compile but I'm sure when I try to assign the card values to the vector deck I'll also get an error since I used variable type 'char'. Knowing what kind of variable type to use seems to be killing me. Also, would 'deck.push_back(card[j] suit[i]);' be the correct code to combine the card and suit, or do you have to put something between card[j] and suit[i]? I'd appreciate it if any of you could lead me in the right direction. Also as a little side note, this is part of a homework assignment so please don't just give me entire blocks of code. Thanks for your help.</p>

<p>Disclaimer: I've solved the problem using Expressions from System.Linq.Expressions, but I'm still looking for a better/easier way.</p>
<p>Consider the following situation :</p>
<pre><code>var query =
from c in db.Customers
where (c.ContactFirstName.Contains("BlackListed") ||
c.ContactLastName.Contains("BlackListed") ||
c.Address.Contains("BlackListed"))
select c;
</code></pre>
<p>The columns/attributes that need to be checked against the blacklisted term are only available to me at runtime. How do I generate this dynamic where clause?</p>
<p>An additional complication is that the Queryable collection (db.Customers above) is typed to a Queryable of the base class of 'Customer' (say 'Person'), and therefore writing c.Address as above is not an option.</p>

<p>I recently stumbled across <a href="http://googletesting.blogspot.com/2008/08/by-miko-hevery-so-you-decided-to.html" rel="noreferrer">this entry in the google testing blog</a> about guidelines for writing more testable code. I was in agreement with the author until this point:</p>
<blockquote>
<p>Favor polymorphism over conditionals: If you see a switch statement you should think polymorphisms. If you see the same if condition repeated in many places in your class you should again think polymorphism. Polymorphism will break your complex class into several smaller simpler classes which clearly define which pieces of the code are related and execute together. This helps testing since simpler/smaller class is easier to test.</p>
</blockquote>
<p>I simply cannot wrap my head around that. I can understand using polymorphism instead of RTTI (or DIY-RTTI, as the case may be), but that seems like such a broad statement that I can't imagine it actually being used effectively in production code. It seems to me, rather, that it would be easier to add additional test cases for methods which have switch statements, rather than breaking down the code into dozens of separate classes.</p>
<p>Also, I was under the impression that polymorphism can lead to all sorts of other subtle bugs and design issues, so I'm curious to know if the tradeoff here would be worth it. Can someone explain to me exactly what is meant by this testing guideline?</p>

<p>I have a collection of elements that I need to operate over, calling member functions on the collection:</p>
<pre><code>std::vector<MyType> v;
... // vector is populated
</code></pre>
<p>For calling functions with no arguments it's pretty straight-forward:</p>
<pre><code>std::for_each(v.begin(), v.end(), std::mem_fun(&MyType::myfunc));
</code></pre>
<p>A similar thing can be done if there's one argument to the function I wish to call.</p>
<p>My problem is that I want to call a function on elements in the vector if it meets some condition. <code>std::find_if</code> returns an iterator to the first element meeting the conditions of the predicate. </p>
<pre><code>std::vector<MyType>::iterator it =
std::find_if(v.begin(), v.end(), MyPred());
</code></pre>
<p>I wish to find <strong>all</strong> elements meeting the predicate and operate over them.</p>
<p>I've been looking at the STL algorithms for a "<code>find_all</code>" or "<code>do_if</code>" equivalent, or a way I can do this with the existing STL (such that I only need to iterate once), rather than rolling my own or simply do a standard iteration using a for loop and comparisons.</p>

<p>This was something originally discussed during a presentation given by Charles Brian Quinn of the <a href="http://www.bignerdranch.com/" rel="noreferrer">Big Nerd Ranch</a> at <a href="http://www.actsasconference.com" rel="noreferrer">acts_as_conference</a>. He was discussing what he had learned from instructing a Ruby on Rails Bootcamp to many people both new to programming and new to Rails.</p>
<p>One particular slide that stood out was along the lines of <strong>never using foo and bar as examples when trying to teach someone to program</strong>. His reasoning was very simple.</p>
<p>Which is easier to understand?</p>
<pre><code>baz = foo + bar
</code></pre>
<p>or</p>
<pre><code>answer = first_number + second_number
</code></pre>
<p>It's happened many times myself when explaining something and I immediately jump to the go to foo bar placeholders but then realize my mistake and make the example make a lot more sense by using a real world scenario. </p>
<p>This is especially applicable when trying to teach someone who has had no programming exposure and you end up needing explain foo and bar before explaining what you're actually trying to teach.</p>
<p>However, using foo and bar for experienced programmers seems OK, though I personally think, along with Charles, that it's something that needs to change.</p>
<p>A quick SO search for "foo" returns over 20 pages of results with foo being used in more ways that I can comprehend. And in some cases where I'm reading a question on a particular language and I'm doing so to help understand that language better. If applicable variable names are used instead of foo and bar, it makes it much easier to understand and interpret the problem. So for seasoned developers, the construct seems a bit flawed as well.</p>
<p>Is this a habit that will ever be able to be kicked? Why do you choose to foo bar or to not foo bar?</p>

<p>I have data that looks like</p>
<blockquote>
<pre><code>CUSTOMER, CUSTOMER_ID, PRODUCT
ABC INC 1 XYX
ABC INC 1 ZZZ
DEF CO 2 XYX
DEF CO 2 ZZZ
DEF CO 2 WWW
GHI LLC 3 ZYX

<p>I'd like to write a query that'd make the data look like this:</p>
<blockquote>
<pre><code>CUSTOMER, CUSTOMER_ID, PRODUCTS
ABC INC 1 XYX, ZZZ
DEF CO 2 XYX, ZZZ, WWW
GHI LLC 3 ZYX
</code></pre>

<p>Using Oracle 10g if helps. I saw something that would work using MYSQL, but I need a plain SQL or ORACLE equivalent. I've also seen examples of stored procs that could be made, however, I cannot use a stored proc with the product i'm using.</p>
<p>Here's how'd it work in MySQL if I were using it</p>
<pre><code>SELECT CUSTOMER,
CUSTOMER_ID,
GROUP_CONCAT( PRODUCT )
FROM MAGIC_TABLE
GROUP BY CUSTOMER, CUSTOMER_ID
</code></pre>
<p>Thank you.</p>

<p>I can't seem to be able to disable ViewState for controls that I add to a page dynamically.</p>
<p><strong>ASPX</strong></p>
<pre><code><%@ Page Language="C#" AutoEventWireup="true" CodeFile="Page1.aspx.cs" Inherits="Page1" EnableViewState="false" %>
...
<asp:PlaceHolder ID="DropDownPlaceHolder" runat="server" EnableViewState="false" />
<asp:Button ID="Submit" runat="server" OnClick="Submit_OnClick" Text="Click Me!" EnableViewState="false"/>
...
</code></pre>
<p><strong>ASPX.CS</strong></p>
<pre><code>protected override void OnInit(EventArgs e)
{
DropDownList dropDown = new DropDownList();
TextBox textBox = new TextBox();
textBox.EnableViewState = false;
dropDown.Items.Add("Apple");
dropDown.Items.Add("Dell");
dropDown.Items.Add("HP");
dropDown.AutoPostBack = true;
dropDown.EnableViewState = false;
DropDownPlaceHolder.Controls.Add(dropDown);
DropDownPlaceHolder.Controls.Add(textBox);
base.OnInit(e);
}
</code></pre>
<p>If I can't disable ViewState on these controls, then I can never programmatically override what a user has entered/selected.</p>
<p>I've tried placing this code in OnInit and Page_Load, but the effect is the same in either location -- ViewState is enabled (the DropDownList maintains selected value and TextBox retains text that was entered).</p>
<p>So, how can I disable ViewState and keep it from populating these controls?</p>
<p>Thanks!</p>
<hr>
<p>Thanks for your response.
Unfortunately, this isn't a workable solution in my situation.</p>
<p>I will be dynamically loading controls based upon a configuration file, and some of those controls will load child controls.</p>
<p>I need to be able to turn the ViewState of controls off individually, without the need to code logic for loading controls in different places (in OnInit vs. LoadComplete
method).</p>

<p>I'm wondering whether anyone here has ever used a <a href="http://en.wikipedia.org/wiki/Skip_list" rel="nofollow noreferrer">skip list</a>. It looks to have roughly the same advantages as a balanced binary tree but is simpler to implement. If you have, did you write your own, or use a pre-written library (and if so, what was its name)?</p>

<p>How do I make <a href="http://en.wikipedia.org/wiki/Vi" rel="noreferrer">vi</a>-<a href="http://en.wikipedia.org/wiki/Vim_%28text_editor%29" rel="noreferrer">Vim</a> never use tabs (converting spaces to tabs, bad!), makes the tab key == 4 spaces, and automatically indent code after curly brace blocks like <a href="http://en.wikipedia.org/wiki/Emacs" rel="noreferrer">Emacs</a> does?</p>
<p>Also, how do I save these settings so I never have to input them again?</p>
<p>I've seen other questions related to this, but it always seems to be a little off from what I want.</p>

<p>One problem that I come across regularly and yet don't have a solution to is to restrict or permit access to specific entities in a system. Some companies (banks, for example) have very strict policies regarding which employees may access certain information. For example, an employee at a specific branch may access account information for customers of that specific branch but not from other branches. Also, banks that have branches in many countries may be subject to legal restrictions that restricts employees in other countries from accessing information about domestic customers.</p>
<p>Another example I've come across is a public website where users belong to a specific entity (such as a company) and may access information regarding that entity only and not other entities.</p>
<p>If the number of entities is small and fixed, this is not a problem. Simply specify domain groups in the active directory (if you're working in Microsoft environments, which is the case for me), add users to the groups and restrict access using IsInRole() for each entity. So if there is a company called ABC in the system I'd create a domain group called "Admins_ABC" or something like that and when a user tries to administer information about ABC, I'd make sure the user is a member of that group. This is not really the way the AD is intended to be used, but for a small number of entities I've found it reasonable.</p>
<p>The complexity increases when the number of entities change often and when the requirements become more detailed. I've seen security requirements that are similar to security in NTFS - some users (or groups of users) should be able to access some entities (files in NTFS) or groups of entities (the permissions that are set on directories in NTFS are propagated to it's children). </p>
<p>I try to avoid situations like these because they tend to be a nightmare to model and code and they usually become complex to administer, but the customers I work with often need solutions to this problem.</p>
<p>Like I said, I have never actually solved this problem in a <em>good</em> way. How would you go about modeling and developing a solution for this problem in a way that can be reused? Do you know of any general, proprietary solutions that can be used?</p>

<p>When doing case-insensitive comparisons, is it more efficient to convert the string to upper case or lower case? Does it even matter?</p>
<p>It is suggested <a href="https://stackoverflow.com/questions/9033/hidden-features-of-c#12137">in this SO post</a> that C# is more efficient with ToUpper because "Microsoft optimized it that way." But I've also read <a href="http://www.petefreitag.com/item/175.cfm" rel="noreferrer">this argument</a> that converting ToLower vs. ToUpper depends on what your strings contain more of, and that typically strings contain more lower case characters which makes ToLower more efficient.</p>
<p>In particular, I would like to know:</p>
<ul>
<li>Is there a way to optimize ToUpper or ToLower such that one is faster than the other?</li>
<li>Is it faster to do a case-insensitive comparison between upper or lower case strings, and why?</li>
<li>Are there any programming environments (eg. C, C#, Python, whatever) where one case is clearly better than the other, and why?</li>
</ul>

<p>In Eclipse, under <kbd>Windows</kbd> -> <kbd>Preference</kbd> -> <kbd>Java</kbd> -> <kbd>Code Style</kbd>, you can define code templates for comments and code, and you can setup a code formatter. </p>
<p>I'm wondering if it is possible in Eclipse to have these setting take affect every time I save a source file. Basically, instead of me highlighting everything and pressing <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>F</kbd>, I want Eclipse to be responsible for making sure my code is formatted properly.</p>
<p>Is this possible and how do you set it up?</p>
<p><strong>Note On Using the Auto-Format:</strong> It's probably best to choose "Format Edited Lines" as merging changes becomes very difficult when you reformat a whole file that is in source control already that was not formatted properly. Already did this to a co-worker.</p>

<p>I would like to use <code>Class.newInstance()</code> but the class I am instantiating does not have a nullary constructor. Therefore I need to be able to pass in constructor arguments. Is there a way to do this?</p>

<p>I have been tasked to optimize some sql queries at work. Everything I have found points to using Explain Plan to identify problem areas. The problem I can not find out exactly what explain plan is telling me. You get Cost, Cardinality, and bytes. </p>
<p>What do this indicate, and how should I be using this as a guide. Are low numbers better? High better? Any input would be greatly appreciated. </p>
<p>Or if you have a better way to go about optimizing a query, I would be interested.</p>

<p>We have a Procedure in Oracle with a SYS_REFCURSOR output parameter that returns the data we want to bind to an ASP.NET GridView control. I've seen this done before but I can't find the original reference I used to solve the problem.</p>
<p>Here is what the procedure looks like:</p>
<pre><code>create or replace PROCEDURE GETSOMEDATA
(
P_Data OUT SYS_REFCURSOR
)
AS
BEGIN
OPEN P_Data FOR SELECT * FROM SOMETABLE;
END GETSOMEDATA;
</code></pre>
<p>And for now the GridView is just bare-bones:</p>
<pre><code><asp:GridView ID="grdData" runat="server" AutoGenerateColumns="true"></asp:GridView>
</code></pre>

<p>Is there a way to have a default parameter passed to a action in the case where the regex didnt match anything using django?</p>
<pre><code>
urlpatterns = patterns('',(r'^test/(?P<name>.*)?$','myview.displayName'))
#myview.py
def displayName(request,name):
# write name to response or something
</code></pre>
<p>I have tried setting the third parameter in the urlpatterns to a dictionary containing ' and giving the name parameter a default value on the method, none of which worked. the name parameter always seems to be None. I really dont want to code a check for None if i could set a default value.</p>
<p>Clarification: here is an example of what i was changing it to.</p>
<pre><code>
def displayName(request,name='Steve'):
return HttpResponse(name)
#i also tried
urlpatterns = patterns('',
(r'^test/(?P<name>.*)?$',
'myview.displayName',
dict(name='Test')
)
)
</code></pre>
<p>when i point my browser at the view it displays the text
'None'</p>
<p>Any ideas?</p>

<p>I have lots of mp3s on my site that I want my friends to be able to play only- but I don't want them all downloading as soon as the page opens and would prefer them to only start downloading into the buffer if someone wants to play it- is this possible with the embed tag? I can't seem to find anything on Google so I am wondering if it's something I'll have to do in JavaScript or think of an HTML work around.</p>
<p>cheers</p>

<p>I was recently approached by a network-engineer, co-worker who would like to offload his minor network admin duties to a junior-level helpdesk tech. The specific location in need of management acts as an ISP for tenants on its single-site property, so there's a lot of small adjustments being made on a daily basis.</p>
<p>I am thinking it would be helpful to write him a winform app to manage the 32 Cisco devices, on-site. I'd like to initially provide functionality which could modify access control lists, port VLAN assignments, and bandwidth limitations per VLAN... adding more to the list as its deemed valuable.</p>
<p><strong>My initial thought was to emulate a telnet session</strong> with the network device; utilizing my network-engineer's familiarity with the command-line / IOS interaction. Minimal time would be required to learn Cisco IOS conventions, myself.</p>
<p><strong>Though while searching for solutions, it appears that most people favor SNMP.</strong> That, or, their specific circumstances pushed them in the direction of SNMP.</p>
<p>I wanted to know if I've overlooked an obvious benefit of SNMP. <strong>Should I be using SNMP? Why or why not?</strong></p>

<p>I would like to redirect <code>www.example.com</code> to <code>example.com</code>. The following htaccess code makes this happen:</p>
<pre><code>RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]
</code></pre>
<p>But, is there a way to do this in a generic fashion without hardcoding the domain name?</p>

<p>Is it possible to serialize and deserialize a class in C++?</p>
<p>I've been using Java for 3 years now, and serialization / deserialization is fairly trivial in that language. Does C++ have similar features? Are there native libraries that handle serialization?</p>
<p>An example would be helpful.</p>

<p>In <code>tcsh</code>, I have the following script working:</p>
<pre><code>#!/bin/tcsh
setenv X_ROOT /some/specified/path
setenv XDB ${X_ROOT}/db
setenv PATH ${X_ROOT}/bin:${PATH}
xrun -d xdb1 -i $1 > $2
</code></pre>
<p>What is the equivalent to the <code>tcsh setenv</code> function in Bash? </p>
<p>Is there a direct analog? The environment variables are for locating the executable.</p>

<p>Is there an easy way to display a messagebox in VB.NET with custom button captions? I came across <em><a href="https://stackoverflow.com/questions/77293/what-is-an-easy-way-to-create-a-messagebox-with-custom-button-text-in-managed-c">What is an easy way to create a MessageBox with custom button text in Managed C++?</a></em>, in the Stack Overflow archives, but it's for <a href="http://en.wikipedia.org/wiki/Managed_Extensions_for_C%2B%2B" rel="noreferrer">Managed C++</a>.</p>

<p>The situation is as follows: I've got 2 models: 'Action' and 'User'. These models refer to the tables 'actions' and 'users', respectively.</p>
<p>My action table contains a column <code>user_id</code>. At this moment, I need an overview of all actions, and the users to which they are assigned to. When i use <code>$action->fetchAll()</code>, I only have the user ID, so I want to be able to join the data from the user model, preferably without making a call to <code>findDependentRowset()</code>.</p>
<p>I thought about creating custom <code>fetchAll()</code>, <code>fetchRow()</code> and <code>find()</code> methods in my model, but this would break default behaviour.</p>
<p>What is the best way to solve this issue? Any help would be greatly appreciated.</p>

<p>I need to use sed to convert all occurences of <code>##XXX##</code> to <code>${XXX}</code>. X could be any alphabetic character or '_'. I know that I need to use something like:</p>
<pre><code>'s/##/\${/g'
</code></pre>
<p>But of course that won't work properly, as it will convert <code>##FOO##</code> to <code>${FOO${</code></p>

<p>I am looking for a way to change the password of a local user account (local Administrator) on a Windows (XP in this case) machine. I have read the <a href="http://www.codeproject.com/KB/threads/Reset-Administrator-Pass.aspx" rel="noreferrer">CodeProject article</a> about one way to do this, but this just doesn't seem 'clean'. </p>
<p>I can see that this is <a href="http://www.microsoft.com/technet/scriptcenter/resources/qanda/oct04/hey1015.mspx" rel="noreferrer">possible to do with WMI</a>, so that might be the answer, but I can't figure out how to use the WinNT WMI namespace with ManagementObject. When I try the following code it throws an "Invalid Parameter" exception.</p>
<pre><code>public static void ResetPassword(string computerName, string username, string newPassword){
ManagementObject managementObject = new ManagementObject("WinNT://" + computerName + "/" + username); // Throws Exception
object[] newpasswordObj = {newPassword};
managementObject.InvokeMethod("SetPassword", newpasswordObj);
}
</code></pre>
<p>Is there a better way to do this? (I'm using .NET 3.5)</p>
<p><strong>Edit:</strong> Thanks Ely for pointing me in the right direction. Here is the code I ended up using:</p>
<pre><code>public static void ResetPassword(string computerName, string username, string newPassword) {
DirectoryEntry directoryEntry = new DirectoryEntry(string.Format("WinNT://{0}/{1}", computerName, username));
directoryEntry.Invoke("SetPassword", newPassword);
}
</code></pre>

<p>I found in MYSQL and apparently other database engines that there is a "greatest" function that can be used like: greatest(1, 2, 3, 4), and it would return 4. I need this, but I am using IBM's DB2. Does anybody know of such an equivalent function, even if it only accepts 2 parameters?</p>
<p>I found somewhere that MAX should do it, but it doesn't work... it only works on selecting the MAX of a column.</p>
<p>If there is no such function, does anybody have an idea what a stored procedure to do this might look like? (I have no stored procedure experience, so I have no clue what DB2 would be capable of).</p>

<p>I am using activemq to pass requests between different processes. In some cases, I have multiple, duplicate message (which are requests) in the queue. I would like to have only one. Is there a way to send a message in a way that it will replace an older message with similar attributes? If there isn't, is there a way to inspect the queue and check for a message with specific attributes (in this case I will not send the new message if an older one exists).</p>
<p>Clarrification (based on Dave's answer): I am actually trying to make sure that there aren't any duplicate messages on the queue to reduce the amount of processing that is happening whenever the consumer gets the message. Hence I would like either to replace a message or not even put it on the queue.</p>
<p>Thanks.</p>

<p>I come from a .NET world and I'm new to writting C++. I'm just wondering what are the preferred naming conventions when it comes to naming local variables and struct members.</p>
<p>For example, the legacy code that I've inheritted has alot of these:</p>
<pre><code>struct MyStruct
{
TCHAR szMyChar[STRING_SIZE];
bool bMyBool;
unsigned long ulMyLong;
void* pMyPointer;
MyObject** ppMyObjects;
}
</code></pre>
<p>Coming from a C# background I was shocked to see the variables with hungarian notation (I couldn't stop laughing at the pp prefix the first time I saw it).</p>
<p>I would much rather name my variables this way instead (although I'm not sure if capitalizing the first letter is a good convention. I've seen other ways (see links below)):</p>
<pre><code>struct MyStruct
{
TCHAR MyChar[STRING_SIZE];
bool MyBool;
unsigned long MyLong;
void* MyPointer;
MyObject** MyObjects;
}
</code></pre>
<p>My question: Is this (the former way) still a preferred way to name variables in C++?</p>

<p>This is a follow on to this <a href="https://stackoverflow.com/questions/232500/how-to-configure-security-when-calling-wcf-service-from-net-20-client">question</a>. I am trying to avoid using the x509 certificate method as that makes my client installs more complex. If basicHttpBinding is not the only option, where are some samples of other binding methods. </p>
<p>My clients are on .Net 2.0, I don't have access to System.ServiceModel namespace as that didn't come out until 3.0.</p>
<p>Update: To be clear,
clients: .Net 2.0,
web service: .net3.5/WCF</p>

<p>I'm going through MSIL and noticing there are a lot of <a href="http://msdn.microsoft.com/en-us/library/system.reflection.emit.opcodes.nop.aspx" rel="nofollow noreferrer">nop</a> instructions in the MSIL.</p>
<p>The MSDN article says they take no action and are used to fill space if the opcode is patched. They're used a lot more in debug builds than release builds.</p>
<p>I know that these kinds of statements are used in assembly languages to align later instructions, but why are MSIL nops needed in MSIL?</p>
<p>(Editor's note: the accepted answer is about machine-code NOPs, not MSIL/CIL NOPs which the question originally asked about.)</p>

<p>I am trying to create a databound WPF GridView whose rows can either be read-only or editable (by double-clicking or through a context menu). I would like for the row to return to a read-only state if any of its editable controls loses focus. The functionality I am looking for is very similar to <a href="http://blogs.msdn.com/atc_avalon_team/archive/2006/03/14/550934.aspx" rel="nofollow noreferrer">this example</a> but with an entire row being editted simultaneously (rather than a single cell). Does anyone know how to implement this?</p>

<pre><code>-(void) doSomethingWithAnimation:(BOOL)animated

<p>or:</p>
<pre><code>-(void) doSomething:(BOOL)animated

<p>I'm having a problem dynamically adding columns to a GridView. I need to change the layout -- i.e. the included columns -- based on the value in a DropDownList. When the user changes the selection in this list, I need to remove all but the first column and dynamically add additional columns based on the selection.</p>
<p>I have only one column defined in my markup -- column 0, a template column, in which I declare a Select link and another application specific LinkButton. That column needs to always be there. When the ListBoxSelection is made, I remove all but the first column and then re-add the desired columns (in this sample, I've simplified it to always add a "Title" column). Here is a portion of the code:</p>
<pre><code>RemoveVariableColumnsFromGrid();
BoundField b = new BoundField();
b.DataField = "Title";
this.gvPrimaryListView.Columns.Add(b);
this.gvPrimaryListView.DataBind();
private void RemoveVariableColumnsFromGrid() {
int ColCount = this.gvPrimaryListView.Columns.Count;
//Leave column 0 -- our select and view template column
while (ColCount > 1) {
this.gvPrimaryListView.Columns.RemoveAt(ColCount - 1);
--ColCount;
}
}
</code></pre>
<p>The first time this code runs through, I see both the static column and the dynamically added "Title" column. However, the next time a selection is made, the first column is generated empty (nothing in it). I see the title column, and I see the first column to its left -- but there's nothing generated within it. In the debugger, I can see that gvPrimaryListView does indeed still have two columns and the first one (index 0) is indeed a template column. In fact, the column even retains it's width which is set as 165px in the markup below (for debugging purposes).</p>
<p>Any ideas?</p>
<pre><code><asp:GridView ID="gvPrimaryListView" runat="server" Width="100%" AutoGenerateColumns="false"
DataKeyNames="Document_ID" EnableViewState="true" DataSourceID="odsPrimaryDataSource"
AllowPaging="true" AllowSorting="true" PageSize="10" OnPageIndexChanging="activeListView_PageIndexChanging"
AutoGenerateSelectButton="False" OnSelectedIndexChanged="activeListView_SelectedIndexChanged"
Visible="true" OnRowDataBound="CtlDocList_RowDataBound" Font-Size="8pt" Font-Names="Helvetica">
<Columns>
<asp:TemplateField ShowHeader="false">
<ItemTemplate>
<asp:LinkButton EnableTheming="false" ID="CtlSelectDocRowBtn" runat="server" Text="Select"
CommandName="Select" CssClass="gridbutton" OnClick="RowSelectBtn_Click" />
<asp:ImageButton EnableTheming="false" ID="DocViewBtn" runat="server" ImageUrl="../../images/ViewDoc3.png"
CssClass="gridbutton" CommandName="Select" OnClick="DocViewBtn_Click" />
</ItemTemplate>
<ItemStyle Width="165px" />
</asp:TemplateField>
</Columns>
<EmptyDataTemplate>
<asp:Label ID="Label6" runat="server" Text="No rows found." SkinID="LabelHeader"></asp:Label>
</EmptyDataTemplate>
</asp:GridView>
</code></pre>
<hr>
<p>Just some additional information.</p>
<p>It has nothing to do with the fact that it is the first column but everything to do with the fact that it is a TemplateField. If I put a normal column to the left (in the markup) and shift the TemplateField column to the right, the first column renders fine, and the (now second) TemplateField column disappears.</p>
<p>Another strange thing -- the problem doesn't happen the first postback -- OR THE SECOND -- but it starts on the third postback and then continues for subsequent postbacks. I'm stumped.</p>

<p>I've inherited a WSDL file for a web service on a system that I don't have access to for development and testing.</p>
<p>I need to generate a web service that adheres to that WSDL. The wrapper is .NET, but if there's an easy way to do this with another platform, we might be able to look at that. The production web service is Java-based.</p>
<p>What's the best way to go about doing this?</p>
<p>Note: The inherited wsdl doesn't appear to be compatible with <b>wsdl.exe</b> because it doesn't conform to WS-I Basic Profile v1.1.
In particular, the group that passed it on mentioned it uses another standard that the Microsoft tool doesn't support, but they didn't clarify. The error is related to a required 'name' field:</p>
<pre>Error: Element Reference '{namespace}/:viewDocumentResponse' declared in
schema type '' from namespace ''
- the required attribute 'name' is missing</pre>
<p>For clarity's sake, I understand that I can easily create a .NET wrapper class from the WSDL file, but that's not what I need. It's like this:</p>
<p>Update: The original web service was created using Axis.</p>

<p>I'm new to CakePHP but I've been though their FAQs and guides to no avail. This is so simple that I just must not be thinking straight:</p>
<p>How can I access a parameter sent through the URL within my view files? </p>
<p>Example: <a href="http://example.com/view/6" rel="nofollow noreferrer">http://example.com/view/6</a></p>
<p>How would I take that parameter ("6") and cycle it through the controller to another view page?</p>
<p>If that's too complex for a quick answer, how can I reference the 6 within the view page itself? The 6 in this situation is the "Id" value in my database, and I need to set it as the "parent" -</p>
<p>Thanks</p>

<p>What is the best way to check for the existence of a session variable in ASP.NET C#? </p>
<p>I like to use <code>String.IsNullOrEmpty()</code> works for strings and wondered if there was a similar method for <code>Session</code>. Currently the only way I know of is:</p>
<pre><code> var session;
if (Session["variable"] != null)
{
session = Session["variable"].ToString();
}
else
{
session = "set this";
Session["variable"] = session;
}
</code></pre>

<p>Scenario - I need to access an HTML template to generate a e-mail from my Business Logic Layer. It is a class library contains a sub folder that contains the file. When I tried the following code in a unit test:</p>
<pre><code>string FilePath = string.Format(@"{0}\templates\MyFile.htm", Environment.CurrentDirectory);
string FilePath1 = string.Format(@"{0}\templates\MyFile.htm", System.AppDomain.CurrentDomain.BaseDirectory);
</code></pre>
<p>It was using the C:\WINNT\system32\ or the ASP.NET Temporary Folder directory.</p>
<p>What is the best to access this file without having to use an app.config or web.config file?</p>
<p>[This is using a WCF Service]</p>

<p>Two questions:</p>
<ol>
<li>Can someone point me to unbiased data that compares .NET performance to VB 6 performance? I have searched but it is surprisingly difficult to find.</li>
<li>What is the best way to compare .NET performance to VB 6 performance as an app behaves at a customer's site?</li>
</ol>
<p>We have a WindowsForms, client-server app (written for 2.0, upgrading to 3.5 SP 1 soon) about which certain customers complain of "slow performance" as compared to the previous VB 6 version. I know, "slow performance" is very vague and general, but is it true to assume .NET code might be slower than VB 6 code because .NET runs in a VM? I wrote 100% of the code in C#, so it was not ported by some third person or wizard.</p>
<p>Not all customers make this complaint, so we suspect something environmental. Is our only option to measure performance at a customer site? Some of our customers use SQL Server 2005 on Windows Server 2003 on a Novell network. Would they see dramatically different data access performance than a similar machine on a Windows network?</p>

<p>I'm practicing for the upcoming ACM programming competition in a week and I've gotten stumped on this programming problem.</p>
<p><strong>The problem is as follows:</strong></p>
<hr>
<p>You have a puzzle consisting of a square grid of size 4. Each grid square holds a single coin; each coin is showing either heads (H) and tails (T). One such puzzle is shown here:</p>
<blockquote>
<p>H H H H<br>
T T T T<br>
H T H T<br>
T T H T </p>
</blockquote>
<p>Any coin that is current showing Tails (T) can be flipped to Heads (H). However, any time we flip a coin, we must also flip the adjacent coins direct above, below and to the left and right in the same row. Thus if we flip the second coin in the second row we must also flip 4 other coins, giving us this arrangment (coins that changed are shown in bold).</p>
<blockquote>
<p>H <strong>T</strong> H H<br>
<strong>H</strong> <strong>H</strong> <strong>H</strong> T<br>
H <strong>H</strong> H T<br>
T T H T </p>
</blockquote>
<p>If a coin is at the edge of the puzzle, so there is no coin on one side or the other, then we flip fewer coins. We do not "wrap around" to the other side. For example, if we flipped the bottom right coin of the arragnement above we would get:</p>
<blockquote>
<p>H T H H<br>
H H H T<br>
H H H <strong>H</strong><br>
T T <strong>T</strong> <strong>H</strong> </p>
</blockquote>
<p>Note: Only coins showing (T) tails can be selected for flipping. However, anytime we flip such a coin, adjacent coins are also flipped, regardless of their state.</p>
<p>The goal of the puzzle is to have all coins show heads. While it is possible for some arragnements to not have solutions, all the problems given will have solutions. The answer we are looking for is, for any given 4x4 grid of coins what is the least number of flips in order to make the grid entirely heads.</p>
<p>For Example the grid:<br>
H T H H<br>
T T T H<br>
H T H T<br>
H H T T </p>
<p>The answer to this grid is: 2 flips.</p>
<hr>
<p>What I have done so far:</p>
<p>I'm storing our grids as two-dimensional array of booleans. Heads = true, tails = false.
I have a <strong>flip(int row, int col)</strong> method that will flip the adjacent coins according the rules above and I have a <strong>isSolved()</strong> method that will determine if the puzzle is in a solved state (all heads). So we have our "mechanics" in place.</p>
<p>The part we are having problems with is how should we loop through, going an the least amount of times deep?</p>

<p><a href="/questions/61400/what-makes-a-good-unit-test">What Makes a Good Unit Test?</a> says that a test should test only one thing. What is the benefit from that?</p>
<p>Wouldn't it be better to write a bit bigger tests that test bigger block of code? Investigating a test failure is anyway hard and I don't see help to it from smaller tests. </p>
<p>Edit: The word unit is not that important. Let's say I consider the unit a bit bigger. That is not the issue here. The real question is why make a test or more for all methods as few tests that cover many methods is simpler.</p>
<p>An example: A list class. Why should I make separate tests for addition and removal? A one test that first adds then removes sounds simpler.</p>

<p>In Delphi, why does the Assigned() function still return True after I call the destructor?</p>
<p>The below example code will write "sl is still assigned" to the console.</p>
<p>However, I can call FreeAndNil(sl); and it won't be assigned.</p>
<p>I've been programming in Delphi for a while, but this never made sense to me.</p>
<p>Can someone explain?</p>
<pre><code>program Project1;
{$APPTYPE CONSOLE}
uses SysUtils, Classes;
var
sl : TStringList;
begin
sl := TStringList.Create;
sl.Free;
if Assigned(sl) then
WriteLn('sl is still assigned')
else
WriteLn('sl is not assigned');
end.
</code></pre>
<p>I tried comparing the VCL operations... FreeAndNil is short and sweet and makes sense:</p>
<pre><code>procedure FreeAndNil(var Obj);
var
P: TObject;
begin
P := TObject(Obj);
TObject(Obj) := nil; // clear the reference before destroying the object
P.Free;
end;
</code></pre>
<p>But TObject.Free is in mysterious assembler, which I don't understand:</p>
<pre><code>procedure TObject.Free;
asm
TEST EAX,EAX
JE @@exit
MOV ECX,[EAX]
MOV DL,1
CALL dword ptr [ECX].vmtDestroy
@@exit:
end;
</code></pre>

<p>I am trying to insert about 50,000 objects (and therefore 50,000 keys) into a <code>java.util.HashMap<java.awt.Point, Segment></code>. However, I keep getting an OutOfMemory exception. (<code>Segment</code> is my own class - very light weight - one <code>String</code> field, and 3 <code>int</code> fields).</p>
<pre>Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at java.util.HashMap.resize(HashMap.java:508)
at java.util.HashMap.addEntry(HashMap.java:799)
at java.util.HashMap.put(HashMap.java:431)
at bus.tools.UpdateMap.putSegment(UpdateMap.java:168)</pre>
<p>This seems quite ridiculous since I see that there is plenty of memory available on the machine - both in free RAM and HD space for virtual memory.</p>
<p>Is it possible Java is running with some stringent memory requirements? Can I increase these?</p>
<p>Is there some weird limitation with <code>HashMap</code>? Am I going to have to implement my own? Are there any other classes worth looking at?</p>
<p>(I am running Java 5 under OS X 10.5 on an Intel machine with 2GB RAM.)</p>

<p>We primarily use an ASP.NET environment at work. Right now I'm building an application which uses "Modules", which is just a UserControl, with its' Javascript right in the control, and a link element to the stylesheet for that control. I want to keep it modular, and would like the style of this control to be independent from the markup/javascript.</p>
<p>So I'm wondering what the preferred method of doing this is? Obviously if I didn't want the "theme" functionality I'm after, I could just use style tags at the top of the control. Right now I have a link element, as I said, and this isn't proper I don't think. </p>
<p>Does anyone have any preferred methods, and if so, what and why?</p>
<hr>
<p>I considered ASP.NET themes briefly, but the idea of these controls are a little different, I think.</p>
<p>It's basically a shopping cart system. I don't want to get into it all, but we are using a really neat security system, and we don't want to use a premade shopping cart. I'm developing a set of controls that can be dropped on a page, for instance in SiteFinity (which is the CMS system we use) or for any other project we might have. Normally I would compile these into a DLL so we get ACTUAL controls we can drag & drop from the toolbox, then I could use internal "generic" styling and allow for any additive styling someone might want, as well as supplying a few fancier styles as well.</p>
<p>This is the first time I've ever done this, or really the first time anyone in our shop has done this either so I'm kind of figuring it out as I go. I might be pretty far off-base, but hopefully I'm not.</p>
<hr>
<p>Right, the idea for this is to have a "theme", which is really just a CSS file and a jQuery template. I have them named the same, and have a Theme property on the usercontrol to set it. </p>
<p>When these controls are finalized, I might refactor the javascript to a RegisterScriptBlock on the code-behind, but for now they just in script tags on the control itself.</p>
<p>What prompted this question was DebugBar for IE, giving me warnings that link elements are not allowed inside a div. I don't much care, but after thinking about it, I had no idea how to link to the css file without doing that. I considered very briefly having an 'empty' link tag on the master and then setting THAT in the code behind on Page_Load of the UserControl, but that just seems like ass.</p>
<p>I could use @import I guess but I think link tags are preferred, correct?</p>

<p>How do you configure cruiseControl to send out emails that contains the error log whenever a build fails? I've gotten it to send out emails to users when the build fails, but it does not include the actual error that caused the build to fail. I know that if I only configure it to send out emails to the users that have made modifications, the error log is included in those emails. This is a sample of what I have:</p>
<p>< publishers><br/>
< rss/><br/>
< xmllogger/> <br/>
< email from="abc@abc.com" mailhost="abc.abc.com" includeDetails="TRUE"><br/>
< users><br/>
< user name="Joe" group="devs" address="joe@abc.com"/><br/>
< user name="Jim" group="devs" address="jim@abc.com"/><br/>
< /users><br/>
< groups><br/>
< group name="devs" notification="Failed"/><br/>
< /groups><br/>
< /email><br/>
< /publishers></p>

<p>I am trying to create a route with a Username...</p>
<p>So the URL would be mydomain.com/abrudtkhul (abrudtkhul being the username)</p>
<p>My application will have public profiles based on usernames (Ex: <a href="http://delicious.com/abrudtkuhl" rel="noreferrer">http://delicious.com/abrudtkuhl</a>). I want to replicate this URL scheme.</p>
<p>How can I structure this in ASP.Net MVC? I am using Membership/Roles Providers too.</p>

<p>In Apple's iPhone apps (like Contacts), they have a nice magnifying glass icon at the top of the table view index. Since the table view index API is character-based, I assume that this magnifying glass is a Unicode character. So far I've resorted to placing a question mark character there, but that looks lame.</p>
<p>Can anyone tell me what character the magnifying glass is?</p>

<p>I am building a Flex Application that calls a .aspx page on the same webserver which builds a PDF report using SQL Reporting Services. When the report is built it prompts the user to open or save the PDF.</p>
<p>We are trying to find a way to display a Progress Bar to let the user know that the report they requested is being built, and then destroy the Progress Bar once the report is finished being built.</p>
<p>I've tried opening a new window using JavaScript and trying to catch when the window closes, as well as trying XMLHTTPRequest, but nothing to seems to work.</p>
<p>Does anyone have any suggestions?</p>

<p>I'm needing to cache some data using <strong>System.Web.Caching.Cache</strong>. Not sure if it matters, but the data does not come from a database, but a plethora of custom objects.</p>
<p>The ASP.NET MVC is fairly new to me and I'm wondering where it makes sense for this caching to occur?</p>
<h3>Model or Controller?</h3>
<p>At some level this makes sense to cache at the <strong>Model</strong> level but I don't necessarily know the implications of doing this (if any). If caching were to be done at the <strong>Controller</strong> level, will that affect all requests, or just for the current <strong>HttpContext</strong>?</p>
<p><strong>So... where should application data caching be done, and what's a good way of actually doing it?</strong></p>
<h3>Update</h3>
<p>Thanks for the great answers! I'm still trying to gather where it makes most sense to cache given different scenarios. If one is caching the entire page, then keeping it in the view makes sense but where to draw the line when it's not the entire page?</p>

<p>I'm currently on chapter 4 of Real World Haskell, and I'm trying to wrap my head around <a href="http://book.realworldhaskell.org/read/functional-programming.html#x_E9" rel="noreferrer">implementing foldl in terms of foldr</a>.</p>
<p>(Here's their code:)</p>
<pre><code>myFoldl :: (a -> b -> a) -> a -> [b] -> a
myFoldl f z xs = foldr step id xs z
where step x g a = g (f a x)
</code></pre>
<p>I thought I'd try to implement <code>zip</code> using the same technique, but I don't seem to be making any progress. Is it even possible?</p>

<pre><code>String^ myString;
StreamWriter sw = gcnew StreamWriter([somehow specify myString])
sw->WriteLine("Foo");
</code></pre>
<p>then myString will contain Foo.
The reason I would like to do this is to reuse a complex function. I should probably refactor it into a String returning function but it still would be a nice hack to know</p>

<p>I'm trying to add parameters to an objectDataSource at runtime like this:</p>
<pre><code> Parameter objCustomerParameter = new Parameter("CustomerID", DbType.String, customerID);
Parameter objGPDatabaseParameter = new Parameter("Database", DbType.String, gpDatabase);
//set up object data source parameters
objCustomer.SelectParameters["CustomerID"] = objCustomerParameter;
objCustomer.SelectParameters["Database"] = objGPDatabaseParameter;
</code></pre>
<p>At what point in the objectDataSource lifecycle should these parameters be added (what event)? Also, some values are coming from a master page property (which loads <em>after</em> the page_load of the page containing the objectDataSource).</p>

<p>What is the best way to make trailing slashes not matter in the latest version of Routes (1.10)? I currently am using the clearly non-DRY:</p>
<pre><code>map.connect('/logs/', controller='logs', action='logs')
map.connect('/logs', controller='logs', action='logs')
</code></pre>
<p>I think that turning minimization on would do the trick, but am under the impression that it was disabled in the newer versions of Routes for a reason. Unfortunately documentation doesn't seem to have caught up with Routes development, so I can't find any good resources to go to. Any ideas?</p>

<p>I am curious to do what happens when you edit a post on this site.</p>
<p>I am using wmd for my markdown editor, of course when I goto edit, I get the HTML it generated not the markdown like on stackoverflow. Now, is there a way I can store both? or is it reliable enough to simply convert the HTML back to markdown to show in the wmd editor?</p>
<p>Thanks!</p>

<p>I am having the worst luck with this. We bought a template to update our own website (don't have enough time to start our own from scratch!) but when I make simple changes in the Flash CS4 native file and re-export the swf, it doesn't work correctly!</p>
<p>I am wondering if anyone has run across the same problems with a Template Monster Flash website template.</p>
<p>Thanks.</p>

<p>Derik Whitaker posted an <a href="http://devlicio.us/blogs/derik_whittaker/archive/2008/10/22/how-is-interacting-with-your-data-repository-in-your-controller-different-or-better-than-doing-it-in-your-code-behind.aspx" rel="noreferrer">article</a> a couple of days ago that hit a point that I've been curious about for some time: <strong>should business logic exist in controllers?</strong></p>
<p>So far all the ASP.NET MVC demos I've seen put repository access and business logic in the controller. Some even throw validation in there as well. This results in fairly large, bloated controllers. Is this really the way to use the MVC framework? It seems that this is just going to end up with a lot of duplicated code and logic spread out across different controllers.</p>

<p>Recently, <a href="https://stackoverflow.com/questions/204814/is-there-any-valid-reason-to-ever-ignore-a-caught-exception">I made a post about the developers I'm working with not using try catch blocks properly</a>, and unfortuantely using try... catch blocks in critical situations and ignoring the exception error all together. causing me major heart ache. Here is an example of one of the several thousand sections of code that they did this (some code left out that doesn't particuarly matter:</p>
<pre><code>public void AddLocations(BOLocation objBllLocations)
{
try
{
dbManager.Open();
if (objBllLocations.StateID != 0)
{
// about 20 Paramters added to dbManager here
}
else
{
// about 19 Paramters added here
}
dbManager.ExecuteNonQuery(CommandType.StoredProcedure, "ULOCATIONS.AddLocations");
}
catch (Exception ex)
{
}
finally
{
dbManager.Dispose();
}
}
</code></pre>
<p>This is absolutely discusting, in my eyes, and does not notify the user in case some potential problem occurred. I know many people say that OOP is evil, and that adding multiple layers adds to the number of lines of code and to the complexity of the program, leading to possible issues with code maintainence. Much of my programming background, I personally, have taken almost the same approach in this area. Below I have listed out a basic structure of the way I normally code in such a situation, and I've been doing this accross many languages in my career, but this particular code is in C#. But the code below is a good basic idea of how I use the Objects, it seems to work for me, but since this is a good source of some fairly inteligent programming mines, I'd like to know If I should re-evaluate this technique that I've used for so many years. Mainly, because, in the next few weeks, i'm going to be plunging into the not so good code from the outsourced developers and modifying huge sections of code. i'd like to do it as well as possible. sorry for the long code reference. </p>

<p>Bottom line, my question is, Am I over complicating things with the muliple layers, and the inherited classes or is my old concept illustrated still working good and stable? Is there a better way now a days to accomplish these things? Should I go to just making straight SQL calls from the asp.net page code behind pages as fellow work associate developer suggested (though that last solution makes me feel icky), instead of going through a business object, and data layer (data layer not shown, but basically holds all the stored proc calls). Yeah, another developer did ask me why i go through the effort of layering things, when you can just type what you need straight in a *.aspx.cs code behind page, and then I can have the joys of over 1k lines of code behind. What is some advice here?</p>

<p>I am trying to connect to 2 databases on the same instance of MySQL from 1 PHP script.</p>
<p>At the moment the only way I've figured out is to connect to both databases with a different user for each.</p>
<p>I am using this in a migration script where I am grabbing data from the original database and inserting it into the new one, so I am looping through large lists of results.</p>
<p>Connecting to 1 database and then trying to initiate a second connection with the same user just changes the current database to the new one.</p>
<p>Any other ideas?</p>

<p>I'm probably doing this all wrong. I have a text file full of data and I want to match and replace patterns of "item" and "catalog number" that are in the file. But the order of each element in the file is very important, so I want to match/replace starting from the top of the file and then work my way down.</p>
<p>The code snippet below actually works, but when I execute it, it replaces the third instance of the "SeaMonkey" & "SMKY-1978" pattern and then it replaces the second instance of that pattern. What I'd like it to do is replace the first instance of the pattern and then the second.</p>
<p>So I'd like the output to say "Found <strong>Kurt's</strong> SMKY-1978 SeaMonkeys" and then "Found <strong>Shane's</strong> SMKY-1978 SeaMonkeys" and then leave Mick's SMKY-1978 SeaMonkeys alone since I only want to find and replace the first 2 instances of the pattern. Right now it says "Found <strong>Shane's</strong> SMKY-1978 SeaMonkeys" and "Found <strong>Mick's</strong> SMKY-1978 SeaMonkeys" because it is matching the last pattern each time the for loop is executed.</p>
<p>So am I missing a subtle little known regex character or am I just doing what I want to do completely and utterly wrong?</p>
<p>Here is the working code:</p>
<pre><code># my regexp matches from the bottom to the top but I'd like it to replace from the top down
local $/=undef;
my $DataToParse = <DATA>;
my $item = "SeaMonkeys";
my $catNum = "SMKY-1978";
my $maxInstancesToReplace = 2;
parseData();
exit();
sub parseData {
for (my $counter = 0; $counter < $maxInstancesToReplace; $counter++) {
# Stick in a temporary text placeholder that I will replace later after more processing
$DataToParse =~ s/(.+)\sELEMENT\s(.+?)\s\(Item := \"$item\".+?CatalogNumber := \"$catNum.+?END_ELEMENT(.+)/$1 ***** Found $2\'s $catNum $item. (counter: $counter) *****$3/s;
}
print("Here's the result:\n$DataToParse\n");
}
__DATA__
ELEMENT Kurt (Item := "BrightLite",
ItemID := 29,
CatalogNumber := "BTLT-9274",
Vendor := 100,
END_ELEMENT

END_ELEMENT

END_ELEMENT

END_ELEMENT
ELEMENT Frank (Item := "PetRock",

END_ELEMENT
ELEMENT Joe (Item := "SeaMonkeys",

<p>I want to hold a bunch of const char pointers into an std::set container [1]. std::set template requires a comparator functor, and the standard C++ library offers std::less, but its implementation is based on comparing the two keys directly, which is not standard for pointers.</p>
<p>I know I can define my own functor and implement the operator() by casting the pointers to integers and comparing them, but is there a cleaner, 'standard' way of doing it?</p>
<p>Please do not suggest creating std::strings - it is a waste of time and space. The strings are static, so they can be compared for (in)equality based on their address.</p>
<p>1: The pointers are to static strings, so there is no problem with their lifetimes - they won't go away.</p>

<p>I'm working on a consumer web app that needs to do a long running background process that is tied to each customer request. By long running, I mean anywhere between 1 and 3 minutes.</p>
<p>Here is an example flow. The object/widget doesn't really matter.</p>
<ol>
<li>Customer comes to the site and specifies object/widget they are looking for.</li>
<li>We search/clean/filter for widgets matching some initial criteria. <-- long running process</li>
<li>Customer further configures more detail about the widget they are looking for.</li>
<li>When the long running process is complete the customer is able to complete the last few steps before conversion. </li>
</ol>
<p>Steps 3 and 4 aren't really important. I just mention them because we can buy some time while we are doing the long running process.</p>
<p>The environment we are working in is a LAMP stack-- currently using PHP. It doesn't seem like a good design to have the long running process take up an apache thread in mod_php (or fastcgi process). The apache layer of our app <em>should</em> be focused on serving up content and not data processing IMO. </p>
<p>A few questions:</p>
<ol>
<li>Is our thinking right in that we should separate this "long running" part out of the apache/web app layer?</li>
<li>Is there a <em>standard/typical</em> way to break this out under Linux/Apache/MySQL/PHP (we're open to using a different language for the processing if appropriate)?</li>
<li>Any suggestions on how to go about breaking it out? E.g. do we create a deamon that churns through a FIFO queue?</li>
</ol>
<p>Edit: Just to clarify, only about 1/4 of the long running process is database centric. We're working on optimizing that part. There is some work that we could potentially do, but we are limited in the amount we can do right now.</p>
<p>Thanks!</p>

<p>Today I had a discussion with a colleague about nested functions in Javascript:</p>
<pre><code>function a() {
function b() {
alert('boo')
}
var c = 'Bound to local call object.'
d = 'Bound to global object.'
}
</code></pre>
<p>In this example, trials point out that b is not reachable outside the body of a, much like c is. However, d is - after executing a(). Looking for the exact definition of this behaviour in the <a href="http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf" rel="noreferrer">ECMAScript v.3 standard </a>, I didn't find the exact wording I was looking for; what Sec.13 p.71 does not say, is which object the function object created by the function declaration statement is to be bound to. Am I missing something?</p>

<p>I've searched around a bit in the small amount of iPhone/iPod Touch development information available and couldn't find anything for or against. Can an application find out information about currently playing song on iPhone/iPod Touch? Since the music can continue to play while you are in 3rd party applications, is there a function or library that will give you information about what is playing? (Track, Artist, Album, etc.) I know generally that applications are sand-boxed but thought maybe there was a way.</p>

<p>Is there any way to add a field to a class at runtime ( a field that didn't exist before ) ? Something like this snippet :</p>
<pre><code>Myobject *ob; // create an object
ob->addField("newField",44); // we add the field to the class and we assign an initial value to it
printf("%d",ob->newField); // now we can access that field
</code></pre>
<p>I don't really care how it would be done , I don't care if it's an ugly hack or not , I would like to know if it could be done , and a small example , if possible .</p>
<p><strong>Another Example:</strong> say I have an XML file describing this class :</p>
<pre><code><class name="MyClass">
<member name="field1" />
<member name="field2" />
</class>
</code></pre>
<p>and I want to "add" the fields "field1" and "field2" to the class (assuming the class already exists) . Let's say this is the code for the class :</p>
<pre><code>class MyClass {
};
</code></pre>
<p>I don't want to create a class at runtime , I just want to add members/fields to an existing one .</p>
<p>Thank you !</p>

<p>In traditional Waterfall, requirements were gathered - typically in a MS-Word document - following an esoteric template. In a "strict" waterfall model, this document is frozen after the requirement phase and a Change Control / Change Management process is responsible for introducing controlled changes. (**) [Typically, the document is turned into a "living document" and eventually a "living nightmare"]</p>
<p>Currently, I've to lead a project that is a rewrite of an existing desktop application to web (from VB 6.0 to ASP.Net). The client has a baselined version of the application that he wants rewritten. [So requirments are frozen... No scope creep]. The data model to be reused as is. Only the front end/Business rules to be migrated. Looking at the application, I feel it's a at most 3/4 major screens and that's it.</p>
<p>Some of the team members want to document (old school of thought, in my opinion) the entire thing before they start on the new development. I & and some others feel, it shoud be relatively easy translate the UI to Web, to look up old code, write the business logic, do automated unit tests, proceed to integration tests and deliver screen by screen (or business function by function)</p>
<p>My question is:
In an Agile development how I do I remain "agile" if I were not to optimize this. My opinion is writing detailed documentation is anti-agile. What do you think? How would an agile guru approach the above problem (of rewriting an existing VB 6.0 app to ASP.Net)?</p>

<p>What's the best way to use NaNs in C++?</p>
<p>I found <code>std::numeric_limits<double>::quiet_NaN()</code> and <code>std::numeric_limits<double>::signaling_NaN()</code>. I'd like to use <code>signaling_NaN</code> to represent an uninitialized variable as follows:</p>
<pre><code>double diameter = std::numeric_limits<double>::signaling_NaN();
</code></pre>
<p>This, however, signals (raises an exception) on assignment. I want it to raise an exception on use, not on assignment.</p>
<p>Is there any way to use <code>signaling_NaN</code> without raising an exception on assignment? Is there a good, portable alternative to <code>signaling_NaN</code> that will raise a floating point exception when used?</p>

<p>In class, we learned about the halting problem, Turing machines, reductions, etc. A lot of classmates are saying these are all abstract and useless concepts, and there's no real point in knowing them (i.e., you can forget them once the course is over and not lose anything).</p>
<p>Why is theory useful? Do you ever use it in your day-to-day coding? </p>

<p>What's the best way to unit test large data sets? Some legacy code that I'm maintaining has structures of a hundred members or more; other parts of the code that we're working on create or analyze data sets of hundreds of samples.</p>
<p>The best approach I've found so far is to serialize the structures or data sets from disk, perform the operations under test, serialize the results to disk, then diff the files containing the serialized results against files containing expected results. This isn't terribly fast, and it violates the "don't touch the disk" principle of unit testing. However, the only alternative I can think of (writing code to initialize and test hundreds of members and data points) seems unbearably tedious.</p>
<p>Are there any better solutions? </p>

<p>I have trouble comparing 2 double in Excel VBA</p>
<p>suppose that I have the following code</p>
<pre><code>Dim a as double
Dim b as double
a = 0.15
b = 0.01
</code></pre>
<p>After a few manipulations on b, b is now equal to 0.6</p>
<p>however the imprecision related to the double data type gives me headache because</p>
<pre><code>if a = b then
//this will never trigger
end if
</code></pre>
<p>Do you know how I can remove the trailing imprecision on the double type?</p>

<p>I have (simplified for the example) a table with the following data</p>
<pre><code>Row Start Finish ID Amount
--- --------- ---------- -- ------
1 2008-10-01 2008-10-02 01 10
2 2008-10-02 2008-10-03 02 20
3 2008-10-03 2008-10-04 01 38
4 2008-10-04 2008-10-05 01 23
5 2008-10-05 2008-10-06 03 14
6 2008-10-06 2008-10-07 02 3
7 2008-10-07 2008-10-08 02 8
8 2008-10-08 2008-11-08 03 19
</code></pre>
<p>The dates represent a period in time, the ID is the state a system was in during that period and the amount is a value related to that state.</p>
<p>What I want to do is to aggregate the Amounts for <em>adjacent</em> rows with the <em>same</em> ID number, but keep the same overall sequence so that contiguous runs can be combined. Thus I want to end up with data like:</p>
<pre><code>Row Start Finish ID Amount
--- --------- ---------- -- ------
1 2008-10-01 2008-10-02 01 10
2 2008-10-02 2008-10-03 02 20
3 2008-10-03 2008-10-05 01 61
4 2008-10-05 2008-10-06 03 14
5 2008-10-06 2008-10-08 02 11
6 2008-10-08 2008-11-08 03 19
</code></pre>
<p>I am after a T-SQL solution that can be put into a SP, however I can't see how to do that with simple queries. I suspect that it may require iteration of some sort but I don't want to go down that path.</p>
<p>The reason I want to do this aggregation is that the next step in the process is to do a SUM() and Count() grouped by the unique ID's that occur within the sequence, so that my final data will look something like:</p>
<pre><code>ID Counts Total
-- ------ -----
01 2 71
02 2 31
03 2 33
</code></pre>
<p>However if I do a simple </p>
<pre><code>SELECT COUNT(ID), SUM(Amount) FROM data GROUP BY ID
</code></pre>
<p>On the original table I get something like</p>
<pre><code>ID Counts Total
-- ------ -----
01 3 71
02 3 31
03 2 33
</code></pre>
<p>Which is not what I want.</p>

<p>I can't seem to find the _findfirst / findfirst, _findnext / findnext API on gcc for Linux, and would actually rather use the Standard Template Library (STL) for that if it is included there.</p>
<p>Does anyone know what API there is available for listing files in a directory under Linux for C++ (gcc)?</p>

<p>Python's access to environment variables does not accurately reflect the operating system's view of the processes environment.</p>
<p>os.getenv and os.environ do not function as expected in particular cases.</p>
<p>Is there a way to properly get the running process' environment?</p>
<hr>
<p>To demonstrate what I mean, take the two roughly equivalent programs (the first in C, the other in python):</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
int main(int argc, char *argv[]){
char *env;
for(;;){
env = getenv("SOME_VARIABLE");
if(env)
puts(env);
sleep(5);
}
}
</code></pre>
<hr>
<pre><code>import os
import time
while True:
env = os.getenv("SOME_VARIABLE")
if env is not None:
print env
time.sleep(5)
</code></pre>
<hr>
<p>Now, if we run the C program and attach to the running process with gdb and forcibly change the environment under the hood by doing something like this:</p>
<pre><code>(gdb) print setenv("SOME_VARIABLE", "my value", 1)
[Switching to Thread -1208600896 (LWP 16163)]
$1 = 0
(gdb) print (char *)getenv("SOME_VARIABLE")
$2 = 0x8293126 "my value"
</code></pre>
<p>then the aforementioned C program will start spewing out "my value" once every 5 seconds. The aforementioned python program, however, will not.</p>
<p>Is there a way to get the python program to function like the C program in this case?</p>
<p>(Yes, I realize this is a very obscure and potentially damaging action to perform on a running process)</p>
<p>Also, I'm currently using python 2.4, this may have been fixed in a later version of python.</p>

<p>Given the following file:</p>
<pre><code>department=value1
location=valueA
location=valueB
department=value2
</code></pre>
<p>I use the following to load the file into a Perl hash:</p>
<pre><code>use File::Slurp;
use Data::Dumper;
my %hash = map {
s/#.*//;
s/^\s+//;
s/\s+$//;
m/(.*?)\s*=\s*(.*)/;
} read_file($file);
print Dumper(\%hash);
</code></pre>
<p>The result, however, is as follows:</p>
<pre><code>$VAR1 = {
'location' => 'valueB',
'department' => 'value2'
};
</code></pre>
<p>How can I load the above file into a hash with, say,</p>
<pre><code>$VAR1 = {
'location' => 'valueA,valueB',
'department' => 'value1,value2'
};
</code></pre>
<p>Thanks.</p>

<p>The way I do 80-column indication in Vim seems incorrect:<code>set columns=80</code>.
At times I also <code>set textwidth</code>, but I want to be able to see and anticipate line overflow with the <code>set columns</code> alternative.</p>
<p>This has some <strong>unfortunate</strong> side effects:</p>
<ol>
<li>I can't <code>set number</code> for fear of splitting between files that have different orders of line numbers; i.e. < 100 line files and >= 100 line files will require two different <code>set columns</code> values because of the extra column used for the additional digit display. </li>
<li>I also start new (g)Vim sessions instead of splitting windows vertically. This is because <code>vsplit</code> forces me to <code>set columns</code> every time I open or close a pane, so starting a new session is less hassle.</li>
</ol>
<p>How do you handle the 80-character indication when you want to <code>set numbers</code>, vertically split, etc.?</p>

<p>Anybody have a slicker way to do this? Seems like it should be easier than this, but I'm having a mental block. Basically I need to remove items from an dictionary and recurse into the values of the items that are also dictionaries.</p>
<pre><code>private void RemoveNotPermittedItems(ActionDictionary menu)
{
var keysToRemove = new List<string>();
foreach (var item in menu)
{
if (!GetIsPermitted(item.Value.Call))
{
keysToRemove.Add(item.Key);
}
else if (item.Value is ActionDictionary)
{
RemoveNotPermittedItems((ActionDictionary)item.Value);
if (((ActionDictionary)item.Value).Count == 0)
{
keysToRemove.Add(item.Key);
}
}
}
foreach (var key in (from item in menu where keysToRemove.Contains(item.Key) select item.Key).ToArray())
{
menu.Remove(key);
}
}
</code></pre>
<p>Action dictionary is like this:</p>
<pre><code>public class ActionDictionary : Dictionary<string, IActionItem>, IActionItem
</code></pre>
