<p>I know the combination <kbd>Ctrl</kbd>+<kbd>A</kbd> to jump to the beginning of the current command, and <kbd>Ctrl</kbd>+<kbd>E</kbd> to jump to the end. </p>
<p>But is there any way to jump word by word, like <kbd>Alt</kbd>+<kbd>←</kbd>/<kbd>→</kbd> in Cocoa applications does?</p>

<p>I re-image one of my machines regularly; and have a script that I run after the OS install completes to configure my machine; such that it works how I like.</p>
<p>I happen to have my data on another drive...and I'd like to add code to my script to change the location of the Documents directory from "C:\Users\bryansh\Documents" to "D:\Users\bryansh\Documents".</p>
<p>Does anybody have any insight, before I fire up regmon and really roll up my sleeves?</p>

<pre><code>struct foo { unsigned x:1; } f;
printf("%d\n", (int)sizeof(f.x = 1));
</code></pre>
<p>What is the expected output and why? Taking the size of a bitfield lvalue directly isn't allowed. But by using the assignment operator, it seems we can still take the size of a bitfield type.</p>
<p>What is the "size of a bitfield in bytes"? Is it the size of the storage unit holding the bitfield? Is it the number of bits taken up by the bf rounded up to the nearest byte count?</p>
<p>Or is the construct undefined behavior because there is nothing in the standard that answers the above questions? Multiple compilers on the same platform are giving me inconsistent results.</p>

<p>I have a webservice that that uses message layer security with X.509 certificates in WSE 3.0. The service uses a X509v3 policy to sign various elements in the soapheader.</p>
<p>I need to do some custom checks on the certificates so I've tried to implement a custom X509SecurityTokenManager and added a section in web.config.</p>
<p>When I call the service with my Wseproxy I would expect a error (NotImplementedException) but the call goes trough and, in the example below, "foo" is printed at the console.</p>
<p>The question is: What have missed? The binarySecurityTokenManager type in web.config matches the full classname of RDI.Server.X509TokenManager. X509TokenManager inherits from
X509SecurityTokenManager (altough methods are just stubs).</p>
<pre><code>using System;
using System.Xml;
using System.Security.Permissions;
using System.Security.Cryptography;
using Microsoft.Web.Services3;
using Microsoft.Web.Services3.Security.Tokens;
namespace RDI.Server
{
[SecurityPermissionAttribute(SecurityAction.Demand,Flags = SecurityPermissionFlag.UnmanagedCode)]
public class X509TokenManager : Microsoft.Web.Services3.Security.Tokens.X509SecurityTokenManager
{
public X509TokenManager() : base()
{
throw new NotImplementedException("Stub");
}
public X509TokenManager(XmlNodeList configData) : base(configData)
{
throw new NotImplementedException("Stub");
}
protected override void AuthenticateToken(X509SecurityToken token)
{
base.AuthenticateToken(token);
throw new NotImplementedException("Stub");
}
}
}
</code></pre>
<p>The first few lines of my web.config, edited for brevity</p>
<pre><code><?xml version="1.0"?>
<configuration><configSections><section name="microsoft.web.services3" type="..." />
</configSections>
<microsoft.web.services3>
<policy fileName="wse3policyCache.config" />
<security>
<binarySecurityTokenManager>
<add type="RDI.Server.X509TokenManager" valueType="http://docs.oasis-open.org/..." />
</binarySecurityTokenManager>
</security>
</microsoft.web.services3>`
</code></pre>
<p>(Btw, how do one format xml nicely here at stackoverflow?)</p>
<pre><code>Administration.AdministrationWse test = new TestConnector.Administration.AdministrationWse();
X509Certificate2 cert = GetCert("RDIDemoUser2");
X509SecurityToken x509Token = new X509SecurityToken(cert);
test.SetPolicy("X509");
test.SetClientCredential(x509Token);
string message = test.Ping("foo");
Console.WriteLine(message);
</code></pre>
<p>I'm stuck at .NET 2.0 (VS2005) for the time being so I presume WCF is out of the question, otherwise interoperability isn't a problem, as I will have control of both clients and services in the system.</p>

<p>We're currently having a debate whether it's better to throw faults over a WCF channel, versus passing a message indicating the status or the response from a service.</p>
<p>Faults come with built-in support from WCF where by you can use the built-in error handlers and react accordingly. This, however, carries overhead as throwing exceptions in .NET can be quite costly.</p>
<p>Messages can contain the necessary information to determine what happened with your service call without the overhead of throwing an exception. It does however need several lines of repetitive code to analyze the message and determine actions following its contents.</p>
<p>We took a stab at creating a generic message object we could utilize in our services, and this is what we came up with:</p>
<pre><code>public class ReturnItemDTO<T>
{
[DataMember]
public bool Success { get; set; }
[DataMember]
public string ErrorMessage { get; set; }
[DataMember]
public T Item { get; set; }
}
</code></pre>
<p>If all my service calls return this item, I can consistently check the "Success" property to determine if all went well. I then have an error message string in the event indicating something went wrong, and a generic item containing a Dto if needed.</p>
<p>The exception information will have to be logged away to a central logging service and not passed back from the service.</p>
<p>Thoughts? Comments? Ideas? Suggestions?</p>
<p><strong>Some further clarification on my question</strong></p>
<p>An issue I'm having with fault contracts is communicating business rules.</p>
<p>Like, if someone logs in, and their account is locked, how do I communicate that? Their login obviously fails, but it fails due to the reason "Account Locked".</p>
<p>So do I:</p>
<p>A) use a boolean, throw Fault with message account locked</p>
<p>B) return AuthenticatedDTO with relevant information</p>

<p>I have been making a little toy web application in C# along the lines of Rob Connery's Asp.net MVC storefront.</p>
<p>I find that I have a repository interface, call it IFooRepository, with methods, say</p>
<pre><code>IQueryable<Foo> GetFoo();
void PersistFoo(Foo foo);
</code></pre>
<p>And I have three implementations of this: ISqlFooRepository, IFileFooRepostory, and IMockFooRepository.</p>
<p>I also have some test cases. What I would like to do, and haven't worked out how to do yet, is to run the same test cases against each of these three implementations, and have a green tick for each test pass on each interface type.</p>
<p>e.g.</p>
<pre><code>[TestMethod]
Public void GetFoo_NotNull_Test()
{
IFooRepository repository = GetRepository();
var results = repository. GetFoo();
Assert.IsNotNull(results);
}
</code></pre>
<p>I want this test method to be run three times, with some variation in the environment that allows it to get three different kinds of repository. At present I have three cut-and-pasted test classes that differ only in the implementation of the private helper method IFooRepository GetRepository(); Obviously, this is smelly.</p>
<p>However, I cannot just remove duplication by consolidating the cut and pasted methods, since they need to be present, public and marked as test for the test to run.</p>
<p>I am using the Microsoft testing framework, and would prefer to stay with it if I can. But a suggestion of how to do this in, say, MBUnit would also be of some interest.</p>

<p>Is there a way to change the encoding used by the String(byte[]) constructor ?</p>
<p>In my own code I use String(byte[],String) to specify the encoding but I am using an external library that I cannot change.</p>
<pre><code>String src = "with accents: é à";
byte[] bytes = src.getBytes("UTF-8");
System.out.println("UTF-8 decoded: "+new String(bytes,"UTF-8"));
System.out.println("Default decoded: "+new String(bytes));
</code></pre>
<p>The output for this is :</p>
<pre>UTF-8 decoded: with accents: é à
Default decoded: with accents: é Ã
</pre>
<p>I have tried changing the system property <code>file.encoding</code> but it does not work.</p>

<p>I hope this question is not considered too basic for this forum, but we'll see. I'm wondering how to refactor some code for better performance that is getting run a bunch of times.</p>
<p>Say I'm creating a word frequency list, using a Map (probably a HashMap), where each key is a String with the word that's being counted and the value is an Integer that's incremented each time a token of the word is found.</p>
<p>In Perl, incrementing such a value would be trivially easy:</p>
<pre><code>$map{$word}++;
</code></pre>
<p>But in Java, it's much more complicated. Here the way I'm currently doing it:</p>
<pre><code>int count = map.containsKey(word) ? map.get(word) : 0;
map.put(word, count + 1);
</code></pre>
<p>Which of course relies on the autoboxing feature in the newer Java versions. I wonder if you can suggest a more efficient way of incrementing such a value. Are there even good performance reasons for eschewing the Collections framework and using a something else instead?</p>
<p>Update: I've done a test of several of the answers. See below.</p>

<p>I have an asp.NET webapplication running in our datacenter in which we want the customer to logon with single sign-on. This would be very easy if we could use the IIS integrated security. However we can't do this. We don't have a trust to the domain controller of the customer. ANd we want to website to be available to the general internet. Only when people are connecting from within the clients network they should automatically login.</p>
<p>What we have is a list of domain accounts and a way to query the DC via LDAP in asp.net code. When anonymous access is allowed in IIS, IIS never challenges the browser for credentials. And thus our application never gets the users credentials.</p>
<p>Is there a way to force the browser into sending the credentials (and thus be able to use single sign-on) with IIS accepting anonymous request.</p>
<p><strong>Update:</strong> </p>
<p>I tried sending 401: unauthorized, www-authenticate: NTLM headers by myself. What happens next (as Fiddler tells me) is that IIS takes complete control and handles the complete chain of request. As I understand from various sources is that IIS takes the username, sends a challenge back to the browser. The browser returns with encrypted reponse and IIS connects to the domain controller to authenticate the user with this response.</p>
<p>However in my scenario IIS is in a different windows domain than the clients and have no way to authenticate the users. For that reason building a seperate site with windows authenticaion enabaled isn't going to work either.</p>
<p>For now I have to options left which I'm researching:</p>
<ol>
<li>Creating a domain trust between our hosting domain and the clients domain (our IT department isn'tto happy with this)</li>
<li>Using a NTML proxy to forward the IIS authentication requests to the clients domain controller (we have a VPN connection available to connect via LDAP) </li>
</ol>

<p>I cannot find an elegant way to get the return value from a stored procedure when using TableAdapters.</p>
<p>It appears the TableAdapter does not support SQL stored procedure return values when using a non-scalar stored procedure call. You'd expect the return value from the auto-generated function would be the return value from the stored procedure but it isn't (it is actually the number of rows affected). Although possible to use 'out' parameters and pass a variable as a ref to the auto generated functions it isn't a very clean solution.</p>
<p>I have seen some ugly hacks on the web to solve this, but no decent solution. Any help would be appreciated.</p>

<p>If you declare variables of type byte or short and attempt to perform arithmetic operations on these, you receive the error "Type mismatch: cannot convert int to short" (or correspondingly "Type mismatch: cannot convert int to byte"). </p>
<pre><code>byte a = 23;
byte b = 34;
byte c = a + b;
</code></pre>
<p>In this example, the compile error is on the third line.</p>

<p>In a server-side application running on Tomcat, I am generating full HTML pages (with header) based on random user-requested sites pulled down from the Internet. The client-side application uses asynchronous callbacks for requesting processing of a particular web page. Since processing can take a while, I want to inform the user about progress via polling, hence the callbacks.</p>
<p>On server-side, after the web page is retrieved, it is processed and an "enhanced" version is created. Then this version has to go back to the user.
Displaying the page as part of the page of the client-side application is not an option.</p>
<p>Currently, the server generates a temporary file and sends back a link to it. This is clearly suboptimal.</p>
<p>The next best solution I can come up with inolves creating a caching-DB that stores the HTML content together with its md5-sums or sha1-ids and then sends back a link to a servlet, with the hash-ID as an argument. The servlet then requests the site from the caching-DB.</p>
<p>Is there any better solution? If not, which DB-backend would you propose? I'm thinking of SQLite. Part of the problem to be solved is: how do I push a page <code><html></code> to <code></html></code> back to client side?</p>

<p>I am planning to create a web app that allows users to downgrade their visual studio project files. However, It seems Google App Engine accepts files uploading and flat file storing on the Google Server through <code>db.TextProperty</code> and <code>db.BlobProperty</code>.</p>
<p>I'll be glad anyone can provide code sample (both the client and the server side) on how this can be done.</p>

<p>I am developing an ASP.NET mobile website using .NET 3.5 and mobile controls that come with the framework. I have a login form where the system will authenticate the user so he/she can access certain restricted pages. </p>
<p>In a standard ASP.NET website, I can use a session to store some flag after a user had logined, but I wonder can I do the same for the mobile version? Is session variable (or cookies) being support by those mobile device's browser? Is there any standard pratice also on doing authentication for mobile pages?</p>

<p>Has anyone gotten VisualWorks running under OpenBSD? It's not an officially supported platform, but one of the Cincom guys was telling me that it should be able to run under a linux compatibility mode. How did you set it up?</p>
<p>I already have Squeak running without a problem, so I'm not looking for an alternative. I specifically need to run VisualWorks's Web Velocity for a project.</p>
<p>Thanks,</p>

<p>I'm writing a J2SE desktop application that requires one of its components to be pluggable. I've already defined the Java interface for this plugin. The user should be able to select at runtime (via the GUI) which implementation of this interface they want to use (e.g. in an initialisation dialog). I envisage each plugin being packaged as a JAR file containing the implementing class plus any helper classes it may require.</p>
<p>What's the best technology for doing this type of thing in a desktop Java app?</p>

<p>I need an encoder that can convert mp3 files to he-aac (aka aac+).
So far the best one I have found is <a href="http://www.nero.com/eng/down-ndaudio.php" rel="nofollow noreferrer">nero aac encoder</a> .
I have two problemes with it :
- Only one input format : wav . It is a little bit slow to transform mp3 files to wav and then to he-aac.
- a free license for <strong>non commercial</strong> use.</p>
<p>Too bad ffmpeg does not support he-aac ...
There is a commercial solution, <a href="https://flix.on2.com/" rel="nofollow noreferrer">on2 flix</a>, but it seems to be a golden hammer for the simple task I need to do.</p>

<p>How can you suppress the <code>Terminated</code> message that comes up after you kill a
process in a bash script?</p>
<p>I tried <code>set +bm</code>, but that doesn't work.</p>
<p>I know another solution involves calling <code>exec 2> /dev/null</code>, but is that
reliable? How do I reset it back so that I can continue to see stderr?</p>

<p>I have settled a web synchronization between SQLSERVER 2005 as publisher and SQLEXPRESS as suscriber. Web synchro has to be launched manually through IE interface (menu tools/synchronize) and to be selected among available synchronizations.</p>
<p>Everything is working fine except that I did not find a way to automate the synchro, which I still have to launch manually. Any idea?</p>
<p>I have no idea if this synchro can be launched from SQLEXPRESS by running a specific T-SQL code (in this case my problem could be solved indirectly).</p>

<p>I'm currently trying to improve the design of a legacy db and I have the following situation</p>
<p>Currently I have a table SalesLead in which we store the the LeadSource.</p>
<pre><code>Create Table SalesLead(
....
LeadSource varchar(20)
....
)
</code></pre>
<p>The Lead Sources are helpfully stored in a table.</p>
<pre><code>Create Table LeadSource (
LeadSourceId int, /*the PK*/
LeadSource varchar(20)
)
</code></pre>
<p>And so I just want to Create a foreign key from one to the other and drop the non-normalized column.</p>
<p>All standard stuff, I hope.</p>
<p>Here is my problem. I can't seem to get away from the issue that instead of writing</p>
<pre><code> SELECT * FROM SalesLead Where LeadSource = 'foo'
</code></pre>
<p>Which is totally unambiguous I now have to write </p>
<pre><code>SELECT * FROM SalesLead where FK_LeadSourceID = 1
</code></pre>
<p>or </p>
<pre><code>SELECT * FROM SalesLead
INNER JOIN LeadSource ON SalesLead.FK_LeadSourceID = LeadSource.LeadSourceId
where LeadSource.LeadSource = "foo"
</code></pre>
<p>Which breaks if we ever alter the content of the LeadSource field.</p>
<p>In my application when ever I want to alter the value of SalesLead's LeadSource I don't want to update from 1 to 2 (for example) as I don't want to have developers having to remember these <strong>magic numbers</strong>. The ids are arbitrary and should be kept so.</p>
<p><strong><em>How do I remove or negate the dependency on them in my app's code?</em></strong></p>
<p><strong>Edit</strong> Languages my solution will have to support</p>
<ul>
<li>.NET 2.0 + 3 (for what its worth asp.net, vb.net and c#)</li>
<li>vba (access)</li>
<li>db (MSSQL 2000)</li>
</ul>
<p><strong>Edit 2.0</strong> The join is fine is just that 'foo' may change on request to 'foobar' and I don't want to haul through the queries.</p>

<p>I feel like I have a very basic/stupid question, yet I never saw/read/heard anything in this direction.</p>
<p>Say I have a table <em>users(userId, name)</em> and a table <em>preferences(id, userId, language)</em>. The example is trivial but could be extended to a situation with multi-level relations and way more tables..<br>
When my UI requests to delete a user I first want to show a warning stating that also its preferences will be deleted. If at some point the database gets extended with more tables and relationships, but the software isn't adapted accordingly (the client didn't update) a generic message should be shown.</p>
<p>How can I implement this? The UI cannot know about the whole data structure and should not be bothered to walk down all the relations to manually delete all the depending records. </p>
<p>I would think this would be with constraints.<br>
The constraint would be <em>no action</em> at first so the constraint will throw an error that can be caught by the UI. After the UI receives a confirmation, the constraint should become a <em>cascade</em>.</p>
<p>Somehow I'm feeling like I'm getting this all wrong..</p>

<p>How do you ensure, that you can checkout the code into Eclipse or NetBeans and work there with it?</p>
<p>Edit: If you not checking in ide-related files, you have to reconfigure buildpath, includes and all this stuff, each time you checkout the project. I don't know, if ant (especially an ant buildfile which is created/exported from eclipse) will work with an other ide seamlessly.</p>

<p>We have in the process of upgrading our application to full Unicode comptibility as we have recently got Delphi 2009 which provides this out of the box. I am looking for anyone who has experience of upgrading an application to accept Unicode characters. Specifically answers to any of the following questions.</p>
<ul>
<li>We need to change VarChars to NVarchar, Char to NChar. Are there any gotchas here.</li>
<li>We need to update all sql statements to include N in front of any sql strings. So Update tbl_Customer set Name = 'Smith' must become Update tbl_Customer set Name = <strong>N</strong>'Smith' . Is there any way to default to this for certain Fields. It seems extraordinary this is still required.</li>
<li>Is it possible to get any defaults set up in SQLServer that will make this simpler?</li>
</ul>
<p>ps We also need to upgrade our Oracle code</p>

<p>How can I find and delete unused references in my projects? </p>
<p>I know you can easily remove the using statements in vs 2008, but this doesn't remove the actual reference in your projects. The referenced dll will still be copied in your bin/setup package.</p>

<p>I'd like to build a query string based on values taken from 5 groups of radio buttons.</p>
<p>Selecting any of the groups is optional so you could pick set A or B or both. How would I build the querystring based on this? I'm using VB.NET 1.1</p>
<p>The asp:Radiobuttonlist control does not like null values so I'm resorting to normal html radio buttons. My question is how do I string up the selected values into a querystring</p>
<p>I have something like this right now:</p>
<p>HTML:</p>
<pre><code><input type="radio" name="apBoat" id="Apb1" value="1" /> detail1
<input type="radio" name="apBoat" id="Apb2" value="2" /> detail2
<input type="radio" name="cBoat" id="Cb1" value="1" /> detail1
<input type="radio" name="cBoat" id="Cb2" value="2" /> detail2
</code></pre>
<p>VB.NET</p>
<pre><code>Public Sub btnSubmit_click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim queryString As String = "nextpage.aspx?"
Dim aBoat, bBoat, cBoat bas String
aBoat = "apb=" & Request("aBoat")
bBoat = "bBoat=" & Request("bBoat")
cBoat = "cBoat=" & Request("cBoat ")
queryString += aBoat & bBoat & cBoat
Response.Redirect(queryString)
End Sub
</code></pre>
<p>Is this the best way to build the query string or should I take a different approach altogether? Appreciate all the help I can get. Thanks much.</p>

<p>For many questions the answer seems to be found in "the standard". However, where do we find that? Preferably online.</p>
<p>Googling can sometimes feel futile, again especially for the C standards, since they are drowned in the flood of discussions on programming forums.</p>
<p>To get this started, since these are the ones I am searching for right now, where are there good online resources for:</p>
<ul>
<li>C89</li>
<li>C99</li>
<li>C11</li>
<li>C++98</li>
<li>C++03</li>
<li>C++11</li>
<li>C++14</li>
<li>C++17</li>

<p>I would like to display an RTF document in an SWT (actually Eclipse RCP) application.</p>
<p>I know there is a Swing widget for displaying and editing RTF text, but it is Swing and quite alien in look and feel when used in the otherwise platform (not to mention that to the last of my knowledge it did not display images and had only limited support for formatting)</p>
<p>Other options is to use COM interface on windows, but that works only on the windows platform and requires that an ActiveX RichEdit contol be installed on the customer machine... which can make the deployment of the application quite horrendous...</p>
<p>What are the other options for displaying rich documents inside Eclipse/SWT application?</p>

<p>I am looking for an easy way to check if an object in C# is serializable.</p>
<p>As we know you make an object serializable by either implementing the <em>ISerializable</em> interface or by placing the <em>[Serializable]</em> at the top of the class.</p>
<p>What I am looking for is a quick way to check this without having to reflect the class to get it's attributes. The interface would be quick using an <em>is</em> statement.</p>
<p>Using @Flard's suggestion this is the code that I have come up with, scream is there is a better way.</p>
<pre><code>private static bool IsSerializable(T obj)
{
return ((obj is ISerializable) || (Attribute.IsDefined(typeof (T), typeof (SerializableAttribute))));
}
</code></pre>
<p>Or even better just get the type of the object and then use the IsSerializable property on the type:</p>
<pre><code>typeof(T).IsSerializable
</code></pre>
<p>Remember though this this seems to only just the class that we are dealing with if the class contains other classes you probably want to check them all or try and serialize and wait for errors as @pb pointed out.</p>

<p>We have a NET app that gets installed to the Program Files folder.
The app itself writes some files and creates some directories to its app folder.
But when a normal windows user tries to use our application it crashes because that user does not have permission to write to app folder.
Is there any folder in both WinXP and WinVista to which all users have writing permissions by default? All User folder or something like that?</p>

<p>Are the any task tracking systems with command-line interface? </p>
<p>Here is a list of features I'm interested in:</p>
<ul>
<li>Simple task template<br>
Something like plain-text file with property:type pairs, for example:</li>
</ul>
<blockquote>
<pre><code>description:string
some-property:integer required
</code></pre>
</blockquote>
<ul>
<li>command line interface<br>
for example: </li>
</ul>
<blockquote>
<pre><code>// Creates task
<task tracker>.exe -create {description: "Foo", some-property: 1}
// Search for tasks with description field starting from F
<task tracker>.exe -find { description: "F*" }
</code></pre>
</blockquote>
<ul>
<li><p>XCopy deployment<br>
It should not require to install heavy DBMS</p></li>
<li><p>Multiple users support<br>
So it's not just a to-do list for a single person</p></li>
</ul>

<p>I am trying to use MinGW to compile a C program under Windows XP. The gcc.exe gives the following error:</p>
<p><strong>stdio.h : No such file or directory</strong></p>
<p>The code (hello.c) looks like this:</p>
<pre><code>#include < stdio.h >
void main()
{
printf("\nHello World\n");
}
</code></pre>
<p>I use a batch file to call gcc. The batch file looks like this:</p>
<pre><code>@echo off
set OLDPATH=%PATH%
set path=C:\devtools\MinGW\bin;%PATH%
set LIBRARY_PATH=C:\devtools\MinGW\lib
set C_INCLUDE_PATH=C:\devtools\MinGW\include
gcc.exe hello.c
set path=%OLDPATH%
</code></pre>
<p>I have tried the option <strong>-I</strong> without effect. What do I do wrong?</p>

<p>I have the concept of <code>NodeType</code>s and <code>Node</code>s. A <code>NodeType</code> is a bunch of meta-data which you can create <code>Node</code> instances from (a lot like the whole Class / Object relationship).</p>
<p>I have various <code>NodeType</code> implementations and various Node implementations. </p>
<p>In my AbstractNodeType (top level for NodeTypes) I have ab abstract <code>createInstance()</code> method that will, once implemented by the subclass, creates the correct Node instance:</p>
<pre><code>public abstract class AbstractNodeType {
// ..
public abstract <T extends AbstractNode> T createInstance();
}
</code></pre>
<p>In my <code>NodeType</code> implementations I implement the method like this:</p>
<pre><code>public class ThingType {
// ..
public Thing createInstance() {
return new Thing(/* .. */);
}
}
// FYI
public class Thing extends AbstractNode { /* .. */ }
</code></pre>
<p>This is all well and good, but <code>public Thing createInstance()</code> creates a warning about type safety. Specifically:</p>
<blockquote>
<p>Type safety: The return type Thing for
createInstance() from the type
ThingType needs unchecked conversion
to conform to T from the type
AbstractNodeType</p>
</blockquote>
<p><strong>What am I doing wrong to cause such a warning?</strong></p>
<p><strong>How can I re-factor my code to fix this?</strong></p>
<p><em><code>@SuppressWarnings("unchecked")</code> is not good, I wish to fix this by coding it correctly, not ignoring the problem!</em></p>

<p>In .NET, after this code, what mechanism stops the <code>Thread</code> object from being garbage collected?</p>
<pre><code>new Thread(Foo).Start();
GC.Collect();
</code></pre>
<p>Yes, it's safe to assume <strong>something</strong> has a reference to the thread, I was just wandering what exactly. For some reason Reflector doesn't show me <code>System.Threading</code>, so I can't dig it myself (I know MS released the source code for the .NET framework, I just don't have it handy).</p>

<p>I've got a virtual machine running on a server that I can't stop or reboot - I can't log onto it anymore and I can't stop it using the VMware server console. There are other VM's running so rebooting the host is out of the question. Is there any other way of forcing one machine to stop?</p>

<p>How do you usually go about <strong>separating your codebase and associated unit tests</strong>? I know people who create a separate project for unit tests, which I personally find confusing and difficult to maintain. On the other hand, if you mix up code and its tests in a single project, you end up with binaries related to your unit test framework (be it NUnit, MbUnit or whatever else) and your own binaries side by side.</p>
<p>This is fine for debugging, but once I build a <strong>release version</strong>, I really do not want my code to <strong>reference the unit testing framework</strong> any more.</p>
<p>One solution I found is to enclose all your unit tests within #if DEBUG -- #endif directives: when no code references an unit testing assembly, the compiler is clever enough to omit the reference in the compiled code.</p>
<p>Are there any other (possibly more comfortable) options to achieve a similar goal?</p>

<p>I'd like to add a method <code>AddDefaultNamespace()</code> to the String class in Java so that I can type <code>"myString".AddDefaultNamespace()</code> instead of <code>DEFAULTNAMESPACE + "myString"</code>, to obtain something like <code>"MyDefaultNameSpace.myString"</code>. I don't want to add another derived class either (<code>PrefixedString</code> for example).</p>
<p>Maybe the approach is not good for you but I personally hate using <code>+</code>. But, anyway, is it possible to add new methods to the String class in Java?</p>
<p>Thanks and regards.</p>

<p>I couldn't find a decent ThreadPool implementation for Ruby, so I wrote mine (based partly on code from here: <a href="http://web.archive.org/web/20081204101031/http://snippets.dzone.com:80/posts/show/3276" rel="nofollow noreferrer">http://web.archive.org/web/20081204101031/http://snippets.dzone.com:80/posts/show/3276</a> , but changed to wait/signal and other implementation for ThreadPool shutdown. However after some time of running (having 100 threads and handling about 1300 tasks), it dies with deadlock on line 25 - it waits for a new job there. Any ideas, why it might happen?</p>
<pre><code>require 'thread'
begin
require 'fastthread'
rescue LoadError
$stderr.puts "Using the ruby-core thread implementation"
end
class ThreadPool
class Worker
def initialize(callback)
@mutex = Mutex.new
@cv = ConditionVariable.new
@callback = callback
@mutex.synchronize {@running = true}
@thread = Thread.new do
while @mutex.synchronize {@running}
block = get_block
if block
block.call
reset_block
# Signal the ThreadPool that this worker is ready for another job
@callback.signal
else
# Wait for a new job
@mutex.synchronize {@cv.wait(@mutex)} # <=== Is this line 25?
end
end
end
end
def name
@thread.inspect
end
def get_block
@mutex.synchronize {@block}
end
def set_block(block)
@mutex.synchronize do
raise RuntimeError, "Thread already busy." if @block
@block = block
# Signal the thread in this class, that there's a job to be done
@cv.signal
end
end
def reset_block
@mutex.synchronize {@block = nil}
end
def busy?
@mutex.synchronize {!@block.nil?}
end
def stop
@mutex.synchronize {@running = false}
# Signal the thread not to wait for a new job
@cv.signal
@thread.join
end
end
attr_accessor :max_size
def initialize(max_size = 10)
@max_size = max_size
@workers = []
@mutex = Mutex.new
@cv = ConditionVariable.new
end
def size
@mutex.synchronize {@workers.size}
end
def busy?
@mutex.synchronize {@workers.any? {|w| w.busy?}}
end
def shutdown
@mutex.synchronize {@workers.each {|w| w.stop}}
end
alias :join :shutdown
def process(block=nil,&blk)
block = blk if block_given?
while true
@mutex.synchronize do
worker = get_worker
if worker
return worker.set_block(block)
else
# Wait for a free worker
@cv.wait(@mutex)
end
end
end
end
# Used by workers to report ready status
def signal
@cv.signal
end
private
def get_worker
free_worker || create_worker
end
def free_worker
@workers.each {|w| return w unless w.busy?}; nil
end
def create_worker
return nil if @workers.size >= @max_size
worker = Worker.new(self)
@workers << worker
worker
end
end

<p>I'd like to encourage our users of our RCP application to send the problem details to our support department. To this end, I've added a "Contact support" widget to our standard error dialogue.</p>
<p>I've managed to use URI headers to send a stacktrace using Java 6's JDIC call: <a href="http://java.sun.com/javase/6/docs/api/java/net/URI.html" rel="nofollow noreferrer"><code>Desktop.getDesktop().mail(java.net.URI)</code></a>. This will fire up the user's mail client, ready for them to add their comments, and hit send. </p>
<p>I like firing up the email client, because it's what the user is used to, it tells support a whole lot about the user (sigs, contact details etc) and I don't really want <a href="http://www.catb.org/~esr/jargon/html/Z/Zawinskis-Law.html" rel="nofollow noreferrer">to ship with Java Mail</a>.</p>
<p>What I'd like to do is attach the log file and the stacktrace as a file, so there is no maximum length requirement, and the user sees a nice clean looking email, and the support department has a lot more information to work with.</p>
<p>Can I do this with the approach I'm taking? Or is there a better way?</p>
<p><strong>Edit</strong>:
I'm in an OSGi context, so bundling JDIC would be necessary. If possible, I'd like to ship with as few dependencies as possible, and bundling up the JDIC for multiple platforms does not sound fun, especially for such a small feature.</p>
<p>JavaMail may be suitable, but for the fact that this will be on desktops of our corporate clients. The <strong>setup/discovery of configuration</strong> would have to be transparent, automatic and reliable. Regarding JavaMail, configuration seems to be manual only. Is this the case?</p>
<p>The answer I like most is using the <code>Desktop.open()</code> for an *.eml file. Unfortunately <strong>Outlook Express (rather than Outlook) opens eml files</strong>. I have no idea if this is usual or default to have Windows configured for to open EML files like this. Is this usual? Or is there another text based format that a) is easy to generate, b) opens by default in the same email client as users would be using already?</p>

<p>I have a script that works fine on my test server (using IIS6). The script processes an ajax request and sends a response with the following line:</p>
<pre><code>header( 'application/javascript' );
</code></pre>
<p>But on my live server, this line crashes the page and causes a 500 error.</p>
<p>Do I need to allow PHP to send different MIME types in IIS7? If so, how do I do this? I can't find any way on the interface.</p>

<p>I have a table in my database the records start and stop times for a specific task. Here is a sample of the data:</p>
<pre><code>Start Stop
9/15/2008 5:59:46 PM 9/15/2008 6:26:28 PM
9/15/2008 6:30:45 PM 9/15/2008 6:40:49 PM
9/16/2008 8:30:45 PM 9/15/2008 9:20:29 PM
9/16/2008 12:30:45 PM 12/31/9999 12:00:00 AM
</code></pre>
<p>I would like to write a script that totals up the elapsed minutes for these time frames, and wherever there is a 12/31/9999 date, I want it to use the current date and time, as this is still in progress.</p>
<p>How would I do this using Transact-SQL?</p>

<p>I need a way to easily export and then import data in a MySQL table from a remote server to my home server. I don't have direct access to the server, and no utilities such as phpMyAdmin are installed. I do, however, have the ability to put PHP scripts on the server.</p>
<p>How do I get at the data?</p>
<p><em>I ask this question purely to record my way to do it</em></p>

<p>The question I want to ask is thus:</p>
<p>Is casting down the inheritance tree (ie. towards a more specialiased class) from inside an abstract class excusable, or even a good thing, or is it always a poor choice with better options available?</p>
<p>Now, the example of why I think it can be used for good.</p>
<p>I recently implemented <a href="http://www.bittorrent.org/beps/bep_0003.html#the-connectivity-is-as-follows" rel="nofollow noreferrer">Bencoding from the BitTorrent protocol</a> in C#. A simple enough problem, how to represent the data. I chose to do it this way,</p>
<p>We have an <code>abstract BItem</code> class, which provides some basic functionality, including the <code>static BItem Decode(string)</code> that is used to decode a Bencoded string into the necessary structure.</p>
<p>There are also four derived classes, <code>BString</code>, <code>BInteger</code>, <code>BList</code> and <code>BDictionary</code>, representing the four different data types that be encoded. Now, here is the tricky part. <code>BList</code> and <code>BDictionary</code> have <code>this[int]</code> and <code>this[string]</code> accessors respectively to allow access to the array-like qualities of these data types.</p>
<p>The potentially horrific part is coming now:</p>
<pre><code>BDictionary torrent = (BDictionary) BItem.DecodeFile("my.torrent");
int filelength = (BInteger)((BDictionary)((BList)((BDictionary)
torrent["info"])["files"])[0])["length"];
</code></pre>
<p>Well, you get the picture... Ouch, that's hard on the eyes, not to mention the brain. So, I introduced something extra into the abstract class:</p>
<pre><code>public BItem this[int index]
{
get { return ((BList)this)[index]; }
}
public BItem this[string index]
{
get { return ((BDictionary)this)[index]; }
}
</code></pre>
<p>Now we could rewrite that old code as:</p>
<pre><code>BDictionary torrent = (BDictionary)BItem.DecodeFile("my.torrent");
int filelength = (BInteger)torrent["info"]["files"][0]["length"];
</code></pre>
<p>Wow, hey presto, MUCH more readable code. But did I just sell part of my soul for implying knowledge of subclasses into the abstract class?</p>
<p>EDIT: In response to some of the answers coming in, you're completely off track for this particular question since the structure is variable, for instance my example of <code>torrent["info"]["files"][0]["length"]</code> is valid, but so is <code>torrent["announce-list"][0][0]</code>, and both would be in 90% of torrent files out there. Generics isn't the way to go, with this problem atleast :(. Have a click through to the spec I linked, it's only 4 small dot-points large.</p>

<p>Every time a user posts something containing <code><</code> or <code>></code> in a page in my web application, I get this exception thrown.</p>
<p>I don't want to go into the discussion about the smartness of throwing an exception or crashing an entire web application because somebody entered a character in a text box, but I am looking for an elegant way to handle this.</p>
<p>Trapping the exception and showing</p>
<blockquote>
<p>An error has occurred please go back and re-type your entire form again, but this time please do not use <</p>
</blockquote>
<p>doesn't seem professional enough to me.</p>
<p>Disabling post validation (<code>validateRequest="false"</code>) will definitely avoid this error, but it will leave the page vulnerable to a number of attacks.</p>
<p>Ideally: When a post back occurs containing HTML restricted characters, that posted value in the Form collection will be automatically HTML encoded.
So the <code>.Text</code> property of my text-box will be <code>something & lt; html & gt;</code></p>
<p>Is there a way I can do this from a handler?</p>

<p>I have a remote DB2 database that I'm accessing through ODBC. When I have a query like</p>
<pre><code>SELECT t.foo, t.bar, t.problemcolumn
FROM problemtable t
WHERE t.bar < 60;
</code></pre>
<p>it works like a charm, so the table and columns obviously exist.</p>
<p>But if I specify the problem column in the WHERE clause</p>
<pre><code>SELECT t.foo, t.bar, t.problemcolumn
FROM problemtable t
WHERE t.problemcolumn = 'x'
AND t.bar < 60;
</code></pre>
<p>it gives me an error </p>
<pre><code>Table "problemtable" does not exist.
</code></pre>
<p>What could possibly be the reason for this? I've double checked the spellings and I can trigger the problem just by including the problemcolumn in the where-clause.</p>

<p>I have xml where some of the element values are unicode characters. Is it possible to represent this in an ANSI encoding?</p>
<p>E.g.</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<xml>
<value>受</value>
</xml>
</code></pre>
<p>to</p>
<pre><code><?xml version="1.0" encoding="Windows-1252"?>
<xml>
<value>&#27544;</value>
</xml>
</code></pre>
<p>I deserialize the XML and then attempt to serialize it using XmlTextWriter specifying the Default encoding (Default is Windows-1252). All the unicode characters end up as question marks. I'm using VS 2008, C# 3.5</p>

<p>I have a requirement to validate an incoming file against an XSD. Both will be on the server file system.<br /></p>
<p>I've looked at <code>dbms_xmlschema</code>, but have had issues getting it to work.</p>
<p>Could it be easier to do it with some Java?<br />What's the simplest class I could put in the database?</p>
<p>Here's a simple example:</p>
<pre><code>DECLARE
v_schema_url VARCHAR2(200) := 'http://www.example.com/schema.xsd';
v_blob bLOB;
v_clob CLOB;
v_xml XMLTYPE;
BEGIN
begin
dbms_xmlschema.deleteschema(v_schema_url);
exception
when others then
null;
end;
dbms_xmlschema.registerSchema(schemaURL => v_schema_url,
schemaDoc => '
<xs:schema targetNamespace="http://www.example.com"
xmlns:ns="http://www.example.com"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified" version="3.0">
<xs:element name="something" type="xs:string"/>
</xs:schema>',
local => TRUE);
v_xml := XMLTYPE.createxml('<something xmlns="http://www.xx.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.example.com/schema.xsd">
data
</something>');
IF v_xml.isschemavalid(v_schema_url) = 1 THEN
dbms_output.put_line('valid');
ELSE
dbms_output.put_line('not valid');
END IF;
END;
</code></pre>
<p>This generates the following error:</p>
<pre><code>ORA-01031: insufficient privileges
ORA-06512: at "XDB.DBMS_XDBZ0", line 275
ORA-06512: at "XDB.DBMS_XDBZ", line 7

<p>Given the following JSON Date representation:</p>
<pre><code>"\/Date(1221644506800-0700)\/"
</code></pre>
<p>How do you deserialize this into it's JavaScript Date-type form?</p>
<p>I've tried using MS AJAX JavaScrioptSerializer as shown below:</p>
<pre><code>Sys.Serialization.JavaScriptSerializer.deserialize("\/Date(1221644506800-0700)\/")
</code></pre>
<p>However, all I get back is the literal string date.</p>

<p>I have a version number of the following form:</p>
<p>version.release.modification</p>
<p>where version, release and modification are either a set of digits or the '*' wildcard character. Additionally, any of these numbers (and any preceding .) may be missing.</p>
<p>So the following are valid and parse as:</p>
<pre><code>1.23.456 = version 1, release 23, modification 456
1.23 = version 1, release 23, any modification
1.23.* = version 1, release 23, any modification
1.* = version 1, any release, any modification
1 = version 1, any release, any modification
* = any version, any release, any modification
</code></pre>
<p>But these are not valid:</p>
<pre><code>*.12
*123.1
12*
12.*.34
</code></pre>
<p>Can anyone provide me a not-too-complex regex to validate and retrieve the release, version and modification numbers?</p>

<p>In a digital signal acquisition system, often data is pushed into an observer in the system by one thread. </p>
<p>example from <a href="http://en.wikipedia.org/wiki/Observer_pattern" rel="nofollow noreferrer">Wikipedia/Observer_pattern</a>:</p>
<pre><code>foreach (IObserver observer in observers)
observer.Update(message);
</code></pre>
<p>When e.g. a user action from e.g. a GUI-thread requires the data to stop flowing, you want to break the subject-observer connection, and even dispose of the observer alltogether.</p>
<p>One may argue: you should just stop the data source, and wait for a sentinel value to dispose of the connection. But that would incur more latency in the system.</p>
<p>Of course, if the data pumping thread has just asked for the address of the observer, it might find it's sending a message to a destroyed object.</p>
<p>Has someone created an 'official' Design Pattern countering this situation? Shouldn't they?</p>

<p>I have create a WCF service and am utilising netMsmqBinding binding.</p>
<p>This is a simple service that passes a Dto to my service method and does not expect a response. The message is placed in an MSMQ, and once picked up inserted into a database.</p>
<p>What is the best method to make sure no data is being lost.</p>
<p>I have tried the 2 following methods:</p>
<ol>
<li><p>Throw an exception</p>
<p>This places the message in a dead letter queue for manual perusal. I can process this when my strvice starts</p>
</li>
<li><p>set the receiveRetryCount="3" on the binding</p>
<p>After 3 tries - which happen instantanously, this seems to leave the message in queue, but fault my service. Restarting my service repeats this process.</p>
</li>
</ol>
<p>Ideally I would like to do the follow:</p>
<p>Try process the message</p>
<ul>
<li>If this fails, wait 5 minutes for that message and try again.</li>
<li>If that process fails 3 times, move the message to a dead letter queue.</li>
<li>Restarting the service will push all messages from the dead letter queue back into the queue so that it can be processed.</li>
</ul>
<p>Can I achieve this? If so how?
Can you point me to any good articles on how best to utilize WCF and MSMQ for my given sceneria.</p>
<p>Any help would be much appreciated. Thanks!</p>
<p><strong>Some additional information</strong></p>
<p>I am using MSMQ 3.0 on Windows XP and Windows Server 2003.
Unfortunately I can't use the built in poison message support targeted at MSMQ 4.0 and Vista/2008.</p>

<p>I am using Java 1.4 with Log4J. </p>
<p>Some of my code involves serializing and deserializing value objects (POJOs). </p>
<p>Each of my POJOs declares a logger with</p>
<pre><code>private final Logger log = Logger.getLogger(getClass());
</code></pre>
<p>The serializer complains of org.apache.log4j.Logger not being Serializable.</p>
<p>Should I use</p>
<pre><code>private final transient Logger log = Logger.getLogger(getClass());
</code></pre>
<p>instead?</p>

<p>I'm new to BIRT and I'm trying to make the Report Engine running. I'm using the code snippets provided in <a href="http://www.eclipse.org/birt/phoenix/deploy/reportEngineAPI.php" rel="nofollow noreferrer">http://www.eclipse.org/birt/phoenix/deploy/reportEngineAPI.php</a></p>
<p>But I have a strange exception:</p>
<blockquote>
<p>java.lang.AssertionError
at org.eclipse.birt.core.framework.Platform.startup(Platform.java:86)</p>
</blockquote>
<p>and nothing in the log file.</p>
<p>Maybe I missed something in the configuration? Could somebody give me a hint about what I can try to make it running?</p>
<p>Here is the code I'm using:</p>
<pre><code>public static void executeReport()
{
IReportEngine engine=null;
EngineConfig config = null;
try{
config = new EngineConfig( );
config.setBIRTHome("D:\\birt-runtime-2_3_0\\ReportEngine");
config.setLogConfig("d:/temp", Level.FINEST);
Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
engine = factory.createReportEngine( config );
IReportRunnable design = null;
//Open the report design
design = engine.openReportDesign("D:\\birt-runtime-2_3_0\\ReportEngine\\samples\\hello_world.rptdesign");
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFileName("output/resample/Parmdisp.html");
options.setOutputFormat("html");
task.setRenderOption(options);
task.run();
task.close();
engine.destroy();
}catch( Exception ex){
ex.printStackTrace();
}
finally
{
Platform.shutdown( );
}
}
</code></pre>

<p>Our build server is taking too long to build one of our C++ projects. It uses <a href="https://en.wikipedia.org/wiki/Microsoft_Visual_Studio#2008" rel="nofollow noreferrer">Visual Studio 2008</a>, running <code>devenv.com MyApp.sln /Build</code> -- see <a href="https://learn.microsoft.com/en-us/visualstudio/ide/reference/devenv-command-line-switches?view=vs-2022" rel="nofollow noreferrer">devenv command-line switches</a> (although that's for a newer version of VS). Is there a way to get devenv.com to log the time taken to build each project in the solution, so that I know where to focus my efforts?</p>
<p>Improved hardware is not an option in this case.</p>
<p>I've tried setting the output verbosity (under menu <em>Tools</em> → <em>Options</em> → <em>Projects and Solutions</em> → <em>Build and Run</em> → <em>MSBuild project build output verbosity</em>). This doesn't seem to have any effect in the IDE.</p>
<p>When running MSBuild from the command line (and, for Visual Studio 2008, it needs to be MSBuild v3.5), it displays the total time elapsed at the end, but not in the IDE.</p>
<p>I really wanted a time-taken report for each project in the solution, so that I could figure out where the build process was taking its time.</p>

<p>I have 6 sound files (1.wav 2.wav etc..) of which 3 different ones have to be heard each time the web page opens. The numbers are selected randomly.
I have tried multiple "embeds" but only the last sound selected gets produced.
I have also tried javascript routines that fiddle the bgsound attribute, however, I was not able to produce more than one sound at a time.
The sounds are required to play either automatically on page open or they can be triggered by a click on a button or link, however, only one click is acceptable for the three sounds.
Is there another way to do this? suggestions very welcome.</p>

<p>Problem:<br/></p>
<ol>
<li>html file on local server (inside our organization) with link to an exe on the same server.</li>
<li>clicking the link runs the exe on the client. Instead I want it to offer downloading it.</li>
</ol>
<p>Tried so far:<br/></p>
<ol>
<li>Changed permissions on the exe's virtual directory to be read and script.</li>
<li>Added Content-disposition header on the exe's directory.</li>
<li>I can't change settings in the browser. It's intended for a lot of people to consume.</li>

<p>I'm experiencing the following very annoying behaviour when using JPA entitys in conjunction with Oracle 10g. </p>
<p>Suppose you have the following entity.</p>
<pre><code>@Entity
@Table(name = "T_Order")
public class TOrder implements Serializable {
private static final long serialVersionUID = 2235742302377173533L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@Column(name = "activationDate")
private Calendar activationDate;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Calendar getActivationDate() {
return activationDate;
}
public void setActivationDate(Calendar activationDate) {
this.activationDate = activationDate;
}
}
</code></pre>
<p>This entity is mapped to Oracle 10g, so in the DB there will be a table <code>T_ORDER</code> with a primary key <code>NUMBER</code> column <code>ID</code> and a <code>TIMESTAMP</code> column <code>activationDate</code>.</p>
<p>Lets suppose I create an instance of this class with the activation date <code>15. Sep 2008 00:00AM</code>. My local timezone is CEST which is <code>GMT+02:00</code>. When I persist this object and select the data from the table <code>T_ORDER</code> using sqlplus, I find out that in the table actually <code>14. Sep 2008 22:00</code> is stored, which is ok so far, because the oracle db timezone is GMT.</p>
<p>But now the annoying part. When I read this entity back into my JAVA program, I find out that the oracle time zone is ignored and I get <code>14. Sep 2008 22:00 CEST</code>, which is definitly wrong. </p>
<p>So basically, when writing to the DB the timezone information will be used, when reading it will be ignored.</p>
<p>Is there any solution for this out there? The most simple solution I guess would be to set the oracle dbs timezone to <code>GMT+02</code>, but unfortunatly I can't do this because there are other applications using the same server.</p>
<p>We use the following technology</p>
<p>MyEclipse 6.5
JPA with Hibernate 3.2
Oracle 10g thin JDBC Driver</p>

<p>I've been given sudo access on one of our development RedHat linux boxes, and I seem to find myself quite often needing to redirect output to a location I don't normally have write access to.</p>
<p>The trouble is, this contrived example doesn't work:</p>
<pre><code>sudo ls -hal /root/ > /root/test.out
</code></pre>
<p>I just receive the response:</p>
<pre><code>-bash: /root/test.out: Permission denied
</code></pre>
<p>How can I get this to work?</p>

<p>Ever wanted to have an HTML drag and drop sortable table in which you could sort both rows and columns? I know it's something I'd die for. There's a lot of sortable lists going around but finding a sortable table seems to be impossible to find. </p>
<p>I know that you can get pretty close with the tools that script.aculo.us provides but I ran into some cross-browser issues with them. </p>

<p>I have to deal with text files in a motley selection of formats. Here's an example (Columns <strong>A</strong> and <strong>B</strong> are tab delimited):</p>
<pre><code>A B
a Name1=Val1, Name2=Val2, Name3=Val3
b Name1=Val4, Name3=Val5
c Name1=Val6, Name2=Val7, Name3=Val8
</code></pre>
<p>The files could have headers or not, have mixed delimiting schemes, have columns with name/value pairs as above etc.<br>
I often have the ad-hoc need to extract data from such files in various ways. For example from the above data I might want the value associated with Name2 where it is present. i.e.</p>
<pre><code>A B
a Val2
c Val7
</code></pre>
<p>What tools/techniques are there for performing such manipulations as one line commands, using the above as an example but extensible to other cases?</p>

<p>I want to place a Webpart on a page that holds a subfolder of the Document Library in SharePoint, but somehow, the only thing I get is the root folder of the document library.</p>
<p>Is there a Webpart that fills this need?</p>

<p>In the uncompressed situation I know I need to read the wav header, pull out the number of channels, bits, and sample rate and work it out from there:
(channels) * (bits) * (samples/s) * (seconds) = (filesize)</p>
<p>Is there a simpler way - a free library, or something in the .net framework perhaps?</p>
<p>How would I do this if the .wav file is compressed (with the mpeg codec for example)?</p>

<p>I have a 3 column grid in a window with a GridSplitter on the first column. I want to set the MaxWidth of the first column to a third of the parent Window or Page <code>Width</code> (or <code>ActualWidth</code>) and I would prefer to do this in XAML if possible.</p>
<p>This is some sample XAML to play with in XamlPad (or similar) which shows what I'm doing. </p>
<pre><code><Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:sys="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition x:Name="Column1" Width="200"/>
<ColumnDefinition x:Name="Column2" MinWidth="50" />
<ColumnDefinition x:Name="Column3" Width="{ Binding ElementName=Column1, Path=Width }"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Background="Green" />
<GridSplitter Grid.Column="0" Width="5" />
<Label Grid.Column="1" Background="Yellow" />
<Label Grid.Column="2" Background="Red" />
</Grid>
</Page>
</code></pre>
<p>As you can see, the right column width is bound to the width of the first column, so when you slide the left column using the splitter, the right column does the same :)
If you slide the left column to the right, eventually it will slide over half the page/window and over to the right side of the window, pushing away column 2 and 3. </p>
<p>I want to prevent this by setting the MaxWidth of column 1 to a third of the window width (or something like that). I can do this in code behind quite easily, but how to do it in "XAML Only"?</p>
<p><strong><em>EDIT:</strong> David Schmitt suggested to use SharedSizeGroup instead of binding, which is an excellent suggestion. My sample code would look like this then:</em></p>
<pre><code><Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:sys="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<Grid IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition x:Name="Column1" SharedSizeGroup="ColWidth" Width="40"/>
<ColumnDefinition x:Name="Column2" MinWidth="50" Width="*" />
<ColumnDefinition x:Name="Column3" SharedSizeGroup="ColWidth"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Background="Green" />
<GridSplitter Grid.Column="0" Width="5" />
<Label Grid.Column="1" Background="Yellow" />
<Label Grid.Column="2" Background="Red" />
</Grid>

<p>I am using C# to process a message in my Outlook inbox that contains attachments. One of the attachments is of type olEmbeddeditem. I need to be able to process the contents of that attachment. From what I can tell I need to save the attachment to disk and use CreateItemFromTemplate which would return an object. </p>
<p>The issue I have is that an olEmbeddeditem can be any of the Outlook object types MailItem, ContactItem, MeetingItem, etc. How do you know which object type a particular olEmbeddeditem attachment is going to be so that you know the object that will be returned by CreateItemFromTemplate?</p>
<p>Alternatively, if there is a better way to get olEmbeddeditem attachment contents into an object for processing I'd be open to that too.</p>

<p>It seems like the methods of Ruby's Net::HTTP are all or nothing when it comes to reading the body of a web page. How can I read, say, the just the first 100 bytes of the body? </p>
<p>I am trying to read from a content server that returns a short error message in the body of the response if the file requested isn't available. I need to read enough of the body to determine whether the file is there. The files are huge, so I don't want to get the whole body just to check if the file is available.</p>

<p>I've just inherited some old Struts code.</p>
<p>If Struts (1.3) follows the MVC pattern, how do the Action classes fill the View with variables to render in HTML ?</p>
<p>So far, I've seen the Action classes push variables in <code>(1)</code> the HTTP request with</p>
<pre><code>request.setAttribute("name", user.getName())
</code></pre>
<p><code>(2)</code> in ActionForm classes, using methods specific to the application:</p>
<pre><code>UserForm form = (UserForm) actionForm;
form.setUserName(user.getName());
</code></pre>
<p>and <code>(3)</code> a requestScope variable, that I see in the JSP layer (the view uses JSP), but I can't see in the Action classes.</p>
<pre><code><p style='color: red'><c:out value='${requestScope.userName}' /></p>
</code></pre>
<p>So, which of these is considered old-school, and what's the recommended way of pushing variables in the View in Struts ?</p>

<p>I'm using the ProgressBar control in a WPF application and I'm getting this old, Windows 3.1 Progress<em>Blocks</em> thing. In VB6, there was a property to show a <em>smooth</em> ProgressBar. Is there such a thing for WPF?</p>

<p>I need to do a multilingual website, with urls like</p>
<pre><code>www.domain.com/en/home.aspx for english
www.domain.com/es/home.aspx for spanish
</code></pre>
<p>In the past, I would set up two virtual directories in IIS, and then detect the URL in global.aspx and change the language according to the URL</p>
<pre><code>Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
Dim lang As String
If HttpContext.Current.Request.Path.Contains("/en/") Then
lang = "en"
Else
lang = "es"
End If
Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(lang)
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(lang)
End Sub
</code></pre>
<p>The solution is more like a hack. I'm thinking about using Routing for a new website. </p>
<p><strong>Do you know a better or more elegant way to do it?</strong></p>
<p>edit: The question is about the URL handling, not about resources, etc.</p>

<p>How would one go about spotting URIs in a block of text?</p>
<p>The idea is to turn such runs of texts into links. This is pretty simple to do if one only considered the http(s) and ftp(s) schemes; however, I am guessing the general problem (considering tel, mailto and other URI schemes) is much more complicated (if it is even possible).</p>
<p>I would prefer a solution in C# if possible. Thank you.</p>

<p>Given the problem that a stored procedure on SQL Server 2005, which is looping through a cursor, must be run once an hour and it takes about 5 minutes to run, but it takes up a large chunk of processor time:</p>
<p>edit: I'd remove the cursor if I could, unfortunatly, I have to be doing a bunch of processing and running other stored procs/queries based on the row.</p>
<p>Can I use
WAITFOR DELAY '0:0:0.1'
before each fetch to act as SQL's version of .Net's Thread.Sleep? Thus allowing the other processes to complete faster at the cost of this procedure's execution time.</p>
<p>Or is there another solution I'm not seeing?</p>
<p>Thanks</p>

<p>Is it possible to hide or exclude certain data from a report if it's being rendered in a particular format (csv, xml, excel, pdf, html).
The problem is that I want hyperlinks to other reports to not be rendered when the report is generated in Excel format - but they should be there when the report is rendered in HTML format.</p>

<p>My understanding of Hibernate is that as objects are loaded from the DB they are added to the Session. At various points, depending on your configuration, the session is flushed. At this point, modified objects are written to the database.</p>
<p>How does Hibernate decide which objects are 'dirty' and need to be written?</p>
<p>Do the proxies generated by Hibernate intercept assignments to fields, and add the object to a dirty list in the Session?</p>
<p>Or does Hibernate look at each object in the Session and compare it with the objects original state?</p>
<p>Or something completely different?</p>

<p>Inspired by the MVC storefront the latest project I'm working on is using extension methods on IQueryable to filter results.</p>
<p>I have this interface;</p>
<pre><code>IPrimaryKey
{
int ID { get; }
}
</code></pre>
<p>and I have this extension method</p>
<pre><code>public static IPrimaryKey GetByID(this IQueryable<IPrimaryKey> source, int id)
{
return source(obj => obj.ID == id);
}
</code></pre>
<p>Let's say I have a class, SimpleObj which implements IPrimaryKey. When I have an IQueryable of SimpleObj the GetByID method doesn't exist, unless I explicitally cast as an IQueryable of IPrimaryKey, which is less than ideal.</p>
<p>Am I missing something here?</p>

<p>Here's one from the "No question's too dumb" department:</p>
<p>Well, as the subject says: Is there an impact? If so, how much? Will all the string literals I have in my code and in my DFM resources now take up twice as much space inside the compiled binaries? What about runtime memory usage of compiled applications? Will all the string variables now take up twice as much RAM? Should I even bother?</p>
<p>I remember something like this being asked during one of the early pre-release webcasts but I can't remember the answer. And as the trial is only 14 days I'm not going to just try it myself before the third-party libraries I need have been updated (supposedly in about a month).</p>

<p>How can I figure out the state of the files in my client, I want to know if the file needs an updated, or patched, or modified etc. In CVS, I used to simply run "cvs -n -q update . > file". Later look for M,U,P,C attributes to get the current status of the file.</p>
<p>In perforce, "p4 sync -n" doesn't give output like "cvs -n -q update". How can I see the current status of files, in case of Perforce?</p>

</blockquote>
<p>I have a .NET console app app that is crashing and displaying a message to the user.
All of my code is in a <code>try{<code>} catch(Exception e){<stuff>}</code> block, but still errors are occasionally displayed.</p>
<p>In a Win32 app, you can capture all possible exceptions/crashes by installing various exception handlers:</p>
<pre><code>/* C++ exc handlers */
_set_se_translator
SetUnhandledExceptionFilter
_set_purecall_handler
set_terminate
set_unexpected
_set_invalid_parameter_handler
</code></pre>
<p>What is the equivalent in the .NET world so I can handle/log/quiet all possible error cases?</p>

<p>I was checking out Intel's "whatif" site and their Transactional Memory compiler (each thread has to make atomic commits or rollback the system's memory, like a Database would). </p>
<p>It seems like a promising way to replace locks and mutexes but I can't find many testimonials. Does anyone here have any input?</p>

<p>Let's say I want a web page that contains a Flash applet and I'd like to drag and drop some objects from or to the rest of the web page, is this at all possible?</p>
<p>Bonus if you know a website somewhere that does that!</p>

<p>I'm on laptop (Ubuntu) with a network that use HTTP proxy (only http connections allowed).<br>
When I use svn up for url like 'http://.....' everything is cool (google chrome repository works perfect), but right now I need to svn up from server with 'svn://....' and I see connection refused.<br>
I've set proxy configuration in /etc/subversion/servers but it doesn't help.<br>
Anyone have opinion/solution?<br></p>
