<p>I'm writing a report view of an audit trail, and I need to display this in a .jsp. What's the "best" way to get the data from the database to the screen?</p>
<p>We're using Spring for dependency injection, Data Access Objects, and Hibernate.
I can use hibernate or straight jdbc for this report.</p>
<p>If I load all the records into memory I run out of memory.</p>
<p>Any ideas that don't involve running the query in the jsp?</p>

<p>First let me say that I really feel directionless on this question. I am using windows integrated security, and I can use vb.net to look up information about a user from AD. I also have other information about users I can look up from a MS SQL 2005 server by getting the logon identity name.</p>
<p>What I would like to do is display information about all the users actively viewing the web page to any one of the users viewing the web page. The information comes both from AD and SQL, and I have no problem retrieving it.</p>
<p>My route so far has been using SQL to store when the user first loads the page. I am stuck not knowing how to show when the user <em>leaves</em> the page. I tried using an ajax timer to update a timestamp for the user's visit every one second that also triggers the table to change the status to inactive of any record that has not been updated in 5 seconds. This works with only a few users, but I find when I have more than a few people viewing the page the 1 second update is not reliable. I also seem to have problems when the user minimizes the page. This sometimes stops the updates from the ajax timer and kicks the user off the list while they are still viewing the page.</p>
<p>This feature is not important to the function of the site it would be on, so I'd given up on it over a year ago. Since then it has really been a pain to me that I can not figure a way to make this work. My searches have led me down many fruitless paths, so I really will appreciate any help that can be offered even if it's only a lead in the correct direction.</p>

<p>Given this class</p>
<pre><code>class Foo
{
// Want to find _bar with reflection
[SomeAttribute]
private string _bar;
public string BigBar
{
get { return this._bar; }
}
}
</code></pre>
<p>I want to find the private item _bar that I will mark with a attribute. Is that possible? </p>
<p>I have done this with properties where I have looked for an attribute, but never a private member field.</p>
<p>What are the binding flags that I need to set to get the private fields?</p>

<p>On my desktop I have written a small Pylons app that connects to Oracle. I'm now trying to deploy it to my server which is running Win2k3 x64. (My desktop is 32-bit XP) The Oracle installation on the server is also 64-bit.</p>
<p>I was getting errors about loading the OCI dll, so I installed the 32 bit client into <code>C:\oracle32</code>.</p>
<p>If I add this to the <code>PATH</code> environment variable, it works great. But I also want to run the Pylons app as a service (<a href="http://wiki.pylonshq.com/display/pylonscookbook/How+to+run+Pylons+as+a+Windows+service" rel="nofollow noreferrer">using this recipe</a>) and don't want to put this 32-bit library on the path for all other applications. </p>
<p>I tried using <code>sys.path.append("C:\\oracle32\\bin")</code> but that doesn't seem to work.</p>

<p>using C++Builder 2007, the FindFirstFile and FindNextFile functions doesn't seem to be able to find some files on 64-bit versions of Vista and XP. My test application is 32-bit.</p>
<p>If I use them to iterate through the folder C:\Windows\System32\Drivers they only find a handful of files although there are 185 when I issue a dir command in a command prompt. Using the same example code lists all files fine on a 32-bit version of XP.</p>
<p>Here is a small example program:</p>
<pre><code>int main(int argc, char* argv[])
{
HANDLE hFind;
WIN32_FIND_DATA FindData;
int ErrorCode;
bool cont = true;
cout << "FindFirst/Next demo." << endl << endl;
hFind = FindFirstFile("*.*", &FindData);
if(hFind == INVALID_HANDLE_VALUE)
{
ErrorCode = GetLastError();
if (ErrorCode == ERROR_FILE_NOT_FOUND)
{
cout << "There are no files matching that path/mask\n" << endl;
}
else
{
cout << "FindFirstFile() returned error code " << ErrorCode << endl;
}
cont = false;
}
else
{
cout << FindData.cFileName << endl;
}
if (cont)
{
while (FindNextFile(hFind, &FindData))
{
cout << FindData.cFileName << endl;
}
ErrorCode = GetLastError();
if (ErrorCode == ERROR_NO_MORE_FILES)
{
cout << endl << "All files logged." << endl;
}
else
{
cout << "FindNextFile() returned error code " << ErrorCode << endl;
}
if (!FindClose(hFind))
{
ErrorCode = GetLastError();
cout << "FindClose() returned error code " << ErrorCode << endl;
}
}
return 0;
}
</code></pre>
<p>Running it in the C:\Windows\System32\Drivers folder on 64-bit XP returns this:</p>
<pre><code>C:\WINDOWS\system32\drivers>t:\Project1.exe
FindFirst/Next demo.
.
..
AsIO.sys
ASUSHWIO.SYS
hfile.txt
raspti.zip
stcp2v30.sys
truecrypt.sys

<p>A dir command on the same system returns this:</p>

<p>Simple question, how do you list the primary key of a table with T-SQL? I know how to get indexes on a table, but can't remember how to get the PK.</p>

<pre><code>Create Table A
(id int identity,
Fname nvarchar(50),
Lname nvarchar(50))
Create Table B
(Fname nvarchar(50),
Lname nvarchar(50),
NewId int)
Insert into A(fname, lname)
SELECT fname, lname
FROM B
</code></pre>
<p>I'm using MS SQL Server 2005.</p>

<p>Let's say I have two models, Classes and People. A Class might have one or two People as instructors, and twenty people as students. So, I need to have multiple relationships between the models -- one where it's 1->M for instructors, and one where it's 1->M for students.</p>
<p>Edit: Instructors and Students <em>must</em> be the same; instructors could be students in other classes, and vice versa.</p>
<p>I'm sure this is quite easy, but Google isn't pulling up anything relevant and I'm just not finding it in my books.</p>

<p>I have an ASP.Net page that will be hosted on a couple different servers, and I want to get the URL of the page (or even better: the site where the page is hosted) as a string for use in the code-behind. Any ideas?</p>

<p>For a developer in the Java eco-system, there is a handful of choices when it comes to UI design. The best known are:</p>
<ul>
<li>Swing (preferred when used with Netbeans and its GUI builder)</li>
<li>Eclipse's SWT (mostly preferred for Eclipse plug-ins)</li>
</ul>
<p>Now, are there any frameworks or design alternatives to this which target JRuby / Groovy / Jython or other "dynamic" JVM languages ?</p>
<p>Some UI frameworks are layers over Swing or SWT, for example, a framework could read a description of a Screen in XML and instantiate the corresponding Swing components.</p>
<p>If you know a framework like that but which targets JVM "dynamic" languages, I'd like to see them in the answers as well.</p>

<p>I'm working on the creation of an ActiveX EXE using VB6, and the only example I got is all written in Delphi.</p>
<p>Reading the example code, I noticed there are some functions whose signatures are followed by the <strong>safecall</strong> keyword. Here's an example:</p>
<pre><code>function AddSymbol(ASymbol: OleVariant): WordBool; safecall;
</code></pre>
<p>What is the purpose of this keyword?</p>

<p>I have huge 3D arrays of numbers in my .NET application. I need to convert them to a 1D array to pass it to a COM library. Is there a way to convert the array without making a copy of all the data?</p>
<p>I can do the conversion like this, but then I use twice the ammount of memory which is an issue in my application:</p>
<pre><code> double[] result = new double[input.GetLength(0) * input.GetLength(1) * input.GetLength(2)];
for (i = 0; i < input.GetLength(0); i++)
for (j = 0; j < input.GetLength(1); j++)
for (k = 0; k < input.GetLength(2); k++)
result[i * input.GetLength(1) * input.GetLength(2) + j * input.GetLength(2) + k)] = input[i,j,l];
return result;
</code></pre>

<p>Suppose I want to store many small configuration objects in XML, and I don't care too much about the format. The <a href="http://java.sun.com/j2se/1.5.0/docs/api/java/beans/XMLDecoder.html" rel="nofollow noreferrer">XMLDecoder</a> class built into the JDK would work, and from what I hear, <a href="http://xstream.codehaus.org/" rel="nofollow noreferrer">XStream</a> works in a similar way.</p>
<p>What are the advantages to each library?</p>

<p>I'm trying to incorporate some JavaScript unit testing into my automated build process. Currently JSUnit works well with JUnit, but it seems to be abandonware and lacks good support for Ajax, debugging, and timeouts.</p>
<p>Has anyone had any luck automating (with <a href="https://en.wikipedia.org/wiki/Apache_Ant" rel="nofollow noreferrer">Ant</a>) a unit testing library such as <a href="https://en.wikipedia.org/wiki/Yahoo!_UI_Library" rel="nofollow noreferrer">YUI</a> test, jQuery's <a href="https://code.jquery.com/qunit/" rel="nofollow noreferrer">QUnit</a>, or <a href="http://code.google.com/p/jqunit/" rel="nofollow noreferrer">jQUnit</a>?</p>
<p>Note: I use a custom built Ajax library, so the problem with Dojo's DOH is that it requires you to use their own Ajax function calls and event handlers to work with any Ajax unit testing.</p>

<p>I've had a lot of trouble trying to come up with the best way to properly follow TDD principles while developing UI in JavaScript. What's the best way to go about this?</p>
<p>Is it best to separate the visual from the functional? Do you develop the visual elements first, and then write tests and then code for functionality?</p>

<p>I'm working with an mpeg stream that uses a IBBP... GOP sequence. The <code>(DTS,PTS)</code> values returned for the first 4 AVPackets are as follows: <code>I=(0,3) B=(1,1) B=(2,2) P=(3,6)</code></p>
<p>The PTS on the I frame looks like it is legit, but then the PTS on the B frames cannot be right, since the B frames shouldn't be displayed before the I frame as their PTS values indicate. I've also tried decoding the packets and using the pts value in the resulting AVFrame, put that PTS is always set to zero.</p>
<p>Is there any way to get an accurate PTS out of ffmpeg? If not, what's the best way to sync audio then?</p>

<p>I'm currently modifying a Java script in Rational Functional Tester and I'm trying to tell RFT to wait for an object with a specified set of properties to appear. Specifically, I want to wait until a table with X number of rows appear. The only way I have been able to do it so far is to add a verification point that just verifies that the table has X number of rows, but I have not been able to utilize the wait for object type of VP, so this seems a little bit hacky. Is there a better way to do this?</p>

<pre><code>Shell ("explorer.exe www.google.com")

<p>is how I'm currently opening my products ad page after successful install. However I think it would look much nicer if I could do it more like Avira does, or even a popup where there are no address bar links etc. Doing this via an inbrowser link is easy enough</p>
<pre><code><a href="http://page.com"
onClick="javascript:window.open('http://page.com','windows','width=650,height=350,toolbar=no,menubar=no,scrollbars=yes,resizable=yes,location=no,directories=no,status=no'); return false")">Link text</a>

<p>But how would I go about adding this functionality in VB?</p>

<p>I have uncovered another problem in the effort that we are making to port several hundreds of ksh scripts from AIX, Solaris and HPUX to Linux. See <a href="https://stackoverflow.com/questions/74372/how-to-overcome-an-incompatibility-between-the-ksh-on-linux-vs-that-installed-o">here</a> for the previous problem.</p>
<p>This code:</p>
<pre><code>#!/bin/ksh
if [ -a k* ]; then
echo "Oh yeah!"
else
echo "No way!"
fi
exit 0
</code></pre>
<p>(when run in a directory with several files whose name starts with k) produces "Oh yeah!" when called with the AT&T ksh variants (ksh88 and ksh93). On the other hand it produces and error message followed by "No way!" on the other ksh variants (pdksh, MKS ksh and bash).</p>
<p>Again, my question are: </p>
<ul>
<li>Is there an environment variable that will cause pdksh to behave like ksh93? Failing that:</li>
<li>Is there an option on pdksh to get the required behavior?</li>
</ul>

<p>There are lots of people out there asking "why shouldn't we use tables for structuring our HTML" and while a lot of answers come in, I rarely see anyone being converted to the world of semantics. That said, I've yet to see any convincing rebuttals to support the rationale for why we should (or might) use tables.</p>
<p>Anyone care to offer a rationale for when tables are valid structural markup?</p>
<hr>
<p>Nov 7, 2008</p>
<p>Considering that this question didn't go away like I thought it would, I suppose I'd better clarify my question and explain its existence.</p>
<p>Through frustration having read the "tables are easier" argument once too many times following the "DIVs vs. TABLEs" question I wanted to expose the question a little more and not let the table lovers get let off the hook so easily.</p>
<p>Each to their own others might say, but I'm forever being given some application to put on our sites that's been created by some 'tables are easier' developer that dumps a chunk of crappy HTML into my pages, and to be honest, I'm just not seeing enough of the table lovers listening to the arguments.</p>
<p>Anyone use Mambo back in the day? Anyone had to take a bash at putting a design on the top of Microsoft's Sharepoint? Having to fight your way through all that nested table crap was hell, and considering that it was written by some bloody good coders annoys the heck out of me. Reasonable semantic markup has been around for long enough that there should be no reason for developers to still be championing "tables are easier". Tables are not easier - they are lazy!</p>
<p>My question deserved the negative rep for the negative manner in which it was presented, but I'm still waiting for people to accept that the only reason they use tables is because THEY DON'T KNOW HTML. Because if they did, then they'd understand, as jjrv says, that tables are for tabular data.</p>

The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server <strong>only</strong>. The application works fine on two other servers (development and testing servers).</p>
<p>The following code generates an 'Unspecified Error' in the Exception.Message.</p>
<p><strong>Quote:</strong></p>
<pre><code> System.Data.OleDb.OleDbConnection x = new System.Data.OleDb.OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + location + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1'");
try
{
x.Open();
}
catch (Exception exp)
{
string errorEmailBody = " OpenExcelSpreadSheet() in Utilities.cs. " + exp.Message;
Utilities.SendErrorEmail(errorEmailBody);
}
</code></pre>
<p><strong>:End Quote</strong></p>
<p>The server's c:\\temp and c:\Documents and Settings\\aspnet\local settings\temp folder both give \aspnet full control.</p>
<p>I believe that there is some kind of permissions issue but can't seem to find any difference between the permissions on the noted folders and the folder/directory where the Excel file is uploaded. The same location is used to save the file and open it and the methods do work on my workstation and two web servers. Windows 2000 SP4 servers.</p>

<p>I am trying to figure out how to click a button on a web page programmatically.</p>
<p>Specifically, I have a WinForm with a WebBrowser control. Once it navigates to the target ASP.NET login page I'm trying to work with, in the DocumentCompleted event handler I have the following coded:</p>
<pre><code>HtmlDocument doc = webBrowser1.Document;
HtmlElement userID = doc.GetElementById("userIDTextBox");
userID.InnerText = "user1";
HtmlElement password = doc.GetElementById("userPasswordTextBox");
password.InnerText = "password";
HtmlElement button = doc.GetElementById("logonButton");
button.RaiseEvent("onclick");
</code></pre>
<p>This fills the userid and password text boxes fine, but I am not having any success getting that darned button to click; I've also tried "click", "Click", and "onClick" -- what else is there?. A search of msdn of course gives me no clues, nor groups.google.com. I gotta be close. Or maybe not -- somebody told me I should call the POST method of the page, but how this is done was not part of the advice given. </p>
<p>BTW The button is coded:</p>
<pre><code><input type="submit" name="logonButton" value="Login" onclick="if (typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); " language="javascript" id="logonButton" tabindex="4" />
</code></pre>

<p>Is it possible to use chapters in videos for the iPhone in an application?</p>
<p>For example:
I have a 3 minutes video to play. I have chapter 1 starting at 0s, chapter 2 at 50s, chapter 3 at 95s.</p>
<p>Can I start plating the video at 50s (chapter 2) until the end? Can I make it play just the chapter 2 from 50s to 95s?</p>
<p>My question is not about how to add chapters to a video. I want to know if this behaviour is available on the iphone.</p>

<p>I'm attempting to convert a home-grown login system to the standard asp.net login control included in .net. I want all communication on the website for a user not logged in to be in clear text, but lock everything in SSL once the user logs in - including the transmission of the username and password.</p>
<p>I had this working before by loading a second page - "loginaction.aspx" - with a https: prefix, then pulling out the username and password by looking for the proper textbox controls in Request.Form.Keys. Is there a way to do something similar using the .net login controls? I dont want to have a seperate login page, but rather include this control (within a loginview) on every page on the site.</p>

<p>The <strong>C</strong> preprocessor is justifiably feared and shunned by the C++ community. In-lined functions, consts and templates are usually a safer and superior alternative to a <code>#define</code>.</p>
<p>The following macro: </p>
<pre><code>#define SUCCEEDED(hr) ((HRESULT)(hr) >= 0)
</code></pre>
<p>is in no way superior to the type safe:</p>
<pre><code>inline bool succeeded(int hr) { return hr >= 0; }
</code></pre>
<p>But macros do have their place, please list the uses you find for macros that you <em>can't</em> do without the preprocessor. </p>
<p>Please put each use-cases in a seperate answer so it can be voted up and if you know of how to achieve one of the answers without the preprosessor point out how in that answer's comments.</p>

<p>When writing manual SQL its pretty easy to estimate the size and shape of data returned by a query. I'm increasingly finding it hard to do this with LINQ to SQL queries. Sometimes I find WAY more data than I was expecting - which can really slow down a remote client that is accessing a database directly.</p>
<p>I'd like to be able to run a query and then tell exactly how much data has been returned across the wire, and use this to help me optimize. </p>
<p>I have already hooked up a log using the DataContext.Log method, but that only gives me an indication of the SQL sent, not the data received.</p>
<p>Any tips?</p>

<p>I create a web application (WAR) and deploy it on Tomcat. In the <em>webapp</em> there is a page with a form where an administrator can enter some configuration data. I don't want to store this data in an DBMS, but just in an XML file on the file system. Where to put it?</p>
<p>I would like to put the file somewhere in the directory tree where the application itself is deployed. Should my configuration file be in the <em>WEB-INF</em> directory? Or put it somewhere else? </p>
<p>And what is the Java code to use in a servlet to find the absolute path of the directory? Or can it be accessed with a relative path?</p>

<p>Adding an element to the head of an alist (Associative list) is simple enough:</p>
<pre><code>> (cons '(ding . 53) '((foo . 42) (bar . 27)))
((ding . 53) (foo . 42) (bar . 27))
</code></pre>
<p>Appending to the tail of an alist is a bit trickier though. After some experimenting, I produced this:</p>
<pre><code>> (define (alist-append alist pair) `(,@alist ,pair))
> (alist-append '((foo . 42) (bar . 27)) '(ding . 53))
'((foo . 42) (bar . 27) (ding . 53))
</code></pre>
<p>However, it seems to me, that this isn't the idiomatic solution. So how is this usually done in scheme? Or is this in fact the way?</p>

<p>My project has both client and server components in the same solution file. I usually have the debugger set to start them together when debugging, but it's often the case where I start the server up outside of the debugger so I can start and stop the client as needed when working on client-side only stuff. (this is much faster). </p>
<p>I'm trying to save myself the hassle of poking around in Solution Explorer to start individual projects and would rather just stick a button on the toolbar that calls a macro that starts the debugger for individual projects (while leaving "F5" type debugging alone to start up both processess). </p>
<p>I tried recording, but that didn't really result in anything useful. </p>
<p>So far all I've managed to do is to locate the project item in the solution explorer: </p>
<pre><code> Dim projItem As UIHierarchyItem
projItem = DTE.ToolWindows.SolutionExplorer.GetItem("SolutionName\ProjectFolder\ProjectName").Select(vsUISelectionType.vsUISelectionTypeSelect)
</code></pre>
<p>(This is based loosely on how the macro recorder tried to do it. I'm not sure if navigating the UI object model is the correct approach, or if I should be looking at going through the Solution/Project object model instead). </p>

<p>I am programming a game on the iPhone. I am currently using NSTimer to trigger my game update/render. The problem with this is that (after profiling) I appear to lose a lot of time between updates/renders and this seems to be mostly to do with the time interval that I plug into NSTimer. </p>
<p>So my question is what is the best alternative to using NSTimer?</p>
<p>One alternative per answer please.</p>

<p>I'm fresh out of college and have been working in C++ for some time now. I understand all the basics of C++ and use them, but I'm having a hard time grasping more advanced topics like pointers and classes. I've read some books and tutorials and I understand the examples in them, but then when I look at some advanced real life examples I cannot figure them out. This is killing me because I feel like its keeping me from bring my C++ programming to the next level. Did anybody else have this problem? If so, how did you break through it?
Does anyone know of any books or tutorials that really describe pointers and class concepts well?
or maybe some example code with good descriptive comments using advanced pointers and class techniques?
any help would be greatly appreciated.</p>

<p>I've got a couple large checkouts where the .svn folder has become damaged so I'm getting and error, "Cleanup failed to process the following path.." And I can no longer commit or update files in that directory.</p>
<p>I'd just delete and do the checkout again but the whole directory is over a gig.</p>
<p>Is there a tool that will restore the .svn folders for specific folders without having to download everything?</p>
<p>I understand that it's going to have to download all the files in that one folder so that it can determine if they've been changed..but subdirectories with valid .svn folders should be fine.</p>
<p>Oh.. I'm a big fan of TortoiseSVN or the command line for linux.</p>
<p>Thoughts?</p>

<p>We have a suite of interlinked .Net 3.5 applications. Some are web sites, some are web services, and some are windows applications. Each app currently has its own configuration file (app.config or web.config), and currently there are some duplicate keys across the config files (which at the moment are kept in sync manually) as multiple apps require the same config value. Also, this suite of applications is deployed across various envrionemnts (dev, test, live etc)</p>
<p>What is the best approach to managing the configuration of these multiple apps from a single configuration source, so configuration values can be shared between multiple apps if required? We would also like to have separate configs for each environment (so when deploying you don't have to manually change certain config values that are environment specific such as conenction strings), but at the same time don't want to maintain multiple large config files (one for each environment) as keeping this in sync when adding new config keys will prove troublesome.</p>

<p>I am trying to use Validation in WPF. I created a NotNullOrEmptyValidationRule as shown below: </p>
<pre><code>public class NotNullOrEmptyValidationRule : ValidationRule
{
public override ValidationResult Validate(object value, CultureInfo cultureInfo)
{
if (String.IsNullOrEmpty(value as String))
return new ValidationResult(false, "Value cannot be null or empty");
return new ValidationResult(true, null);
}
}
</code></pre>
<p>Now, I need to use it in my application. In my App.xaml file I declared the Style for the TextBox. Here is the declaration. </p>
<pre><code> <Style x:Key="textBoxStyle" TargetType="{x:Type TextBox}">
<Setter Property="Background" Value="Green"/>
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="True">
<Setter Property="Background" Value="Red"/>
<Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self},Path=(Validation.Errors)[0].ErrorContent}"/>
</Trigger>
</Style.Triggers>
</Style>
</code></pre>
<p>Now, I want to use it on my TextBox so I am using the following code: </p>
<pre><code> <TextBox Style="{StaticResource textBoxStyle}">
<TextBox.Text>
<Binding>
<Binding.ValidationRules>
<NotNullOrEmptyValidationRule />
</Binding.ValidationRules>
</Binding>
</TextBox.Text>
</TextBox>
</code></pre>
<p>The error comes on the Tag NotNullOrEmptyValidationRule. The XAML syntax checker is not able to resolve the NotNullOrEmptyValidationRule. I have even tried putting the namespace but it does not seem to work. </p>

<p>I have a SQL statement that looks like:</p>
<pre><code>SELECT [Phone]
FROM [Table]
WHERE
(
[Phone] LIKE '[A-Z][a-z]'
OR [Phone] = 'N/A'
OR [Phone] LIKE '[0]'
)
</code></pre>
<p>The part I'm having trouble with is the where statement with the "LIKEs". I've seen SQL statements where authors used <code>like</code> statements in the way I'm using them above. At first, I thought this might be a version of Regular Expressions but I've since learned. </p>
<p>Is anyone familiar with using like statements in such a way. Note: the "N/A" is working fine. </p>
<p>What I need to match is phone numbers that have characters. Or phone numbers which contain nothing but zero.</p>

<p>I'm experimenting with adding icons to a shell extension. I have this code (sanitized for easy reading), which works:</p>
<pre><code>InsertMenu(hmenu, index, MF_POPUP|MF_BYPOSITION, (UINT)hParentMenu, namestring);
</code></pre>
<p>The next step is this code:</p>
<pre><code>HICON hIconLarge, hIconSmall;
ICONINFO oIconInfo;
ExtractIconEx("c:\\progra~1\\winzip\\winzip32.exe", 0, &hIconLarge, &hIconSmall, 1);
GetIconInfo(hIconSmall, &oIconInfo);
//???????
SetMenuItemBitmaps(hParentMenu, indexMenu-1, MF_BITMAP | MF_BYPOSITION, hbmp, hbmp);
</code></pre>
<p>What do I put in to replace the ?'s. Attempts to Google this knowledge have found many tips that I failed to get working. Any advice on getting this to work, especially on older machines (e.g. no .net framework, no vista) is appreciated.</p>

<p>I have a Flex application, which loads a SWF from CS3. The loaded SWF contains a text input called "myText". I can see this in the SWFLoader.content with no problems, but I don't know what type I should be treating it as in my Flex App. I thought the flex docs covered this but I can only find how to interact with another Flex SWF.</p>
<p>The Flex debugger tells me it is of type fl.controls.TextInput, which makes sense. But FlexBuilder doesn't seem to know this class. While Flash and Flex both use AS3, Flex has a whole new library of GUI classes. I thought it also had all the Flash classes, but I can't get it to know of ANY fl.*** packages.</p>

<p>I need to import a large CSV file into an SQL server. I'm using this :</p>
<pre><code>BULK
INSERT CSVTest
FROM 'c:\csvfile.txt'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
GO
</code></pre>
<p>problem is all my fields are surrounded by quotes (" ") so a row actually looks like :</p>
<pre><code>"1","","2","","sometimes with comma , inside", ""
</code></pre>
<p>Can I somehow bulk import them and tell SQL to use the quotes as field delimiters?</p>
<p><strong>Edit</strong>: The problem with using '","' as delimiter, as in the examples suggested is that :
What most examples do, is they import the data including the first " in the first column and the last " in the last, then they go ahead and strip that out. Alas my first (and last) column are datetime and will not allow a "20080902 to be imported as datetime.</p>
<p>From what I've been reading arround I think FORMATFILE is the way to go, but documentation (including MSDN) is terribly unhelpfull.</p>

<p>How do you access the response from the Request
object in MooTools? I've been looking at the documentation and the MooTorial, but
I can't seem to make any headway. Other Ajax stuff I've done with
MooTools I haven't had to manipulate the response at all, so I've just
been able to inject it straight into the document, but now I need to
make some changes to it first. I don't want to alert the response, I'd like to access it so I can make further changes to it. Any help would be greatly appreciated.
Thanks.</p>
<p>Edit:</p>
<p>I'd like to be able to access
the response after the request has already been made, preferably
outside of the Request object. It's for an RSS reader, so I need to do
some parsing and Request is just being used to get the feed from a
server file. This function is a method in a class, which should return
the response in a string, but it isn't returning anything but
undefined:</p>
<pre><code> fetch: function(site){
var feed;
var req = new Request({
method: this.options.method,
url: this.options.rssFetchPath,
data: { 'url' : site },
onRequest: function() {
if (this.options.targetId) { $
(this.options.targetId).setProperty('html',
this.options.onRequestMessage); }
}.bind(this),
onSuccess: function(responseText) {
feed = responseText;
}
});
req.send();
return feed;
}
</code></pre>

<p>Suppose I have the following code:</p>
<pre><code>class some_class{};
some_class some_function()
{
return some_class();
}
</code></pre>
<p>This seems to work pretty well and saves me the trouble of having to declare a variable just to make a return value. But I don't think I've ever seen this in any kind of tutorial or reference. Is this a compiler-specific thing (visual C++)? Or is this doing something wrong?</p>

<p>Is it possible to change the font size used in a ContextMenu using the .NET Framework 3.5 and C# for a desktop application? It seems it's a system-wide setting, but I would like to change it only within my application.</p>

<p>We have multiple MFC apps, which use CMutex( false, "blah" ), where "blah" allows the mutex to work across process boundaries.</p>
<p>One of these apps was re-written without MFC (using Qt instead). How can I simulate the CMutex using Win32 calls? (Qt's QMutex is not inter-process.) I prefer not to modify the MFC apps.</p>

<p>This isn't legal:</p>
<pre><code>public class MyBaseClass
{
public MyBaseClass() {}
public MyBaseClass(object arg) {}
}
public void ThisIsANoNo<T>() where T : MyBaseClass
{
T foo = new T("whoops!");
}
</code></pre>
<p>In order to do this, you have to do some reflection on the type object for T or you have to use Activator.CreateInstance. Both are pretty nasty. Is there a better way?</p>

<p>Is it particularly bad to have a very, very large SQL query with lots of (potentially redundant) WHERE clauses?</p>
<p>For example, here's a query I've generated from my web application with everything turned off, which should be the largest possible query for this program to generate:</p>
<pre><code>SELECT *
FROM 4e_magic_items
INNER JOIN 4e_magic_item_levels
ON 4e_magic_items.id = 4e_magic_item_levels.itemid
INNER JOIN 4e_monster_sources
ON 4e_magic_items.source = 4e_monster_sources.id
WHERE (itemlevel BETWEEN 1 AND 30)
AND source!=16 AND source!=2 AND source!=5
AND source!=13 AND source!=15 AND source!=3
AND source!=4 AND source!=12 AND source!=7
AND source!=14 AND source!=11 AND source!=10
AND source!=8 AND source!=1 AND source!=6
AND source!=9 AND type!='Arms' AND type!='Feet'
AND type!='Hands' AND type!='Head'
AND type!='Neck' AND type!='Orb'
AND type!='Potion' AND type!='Ring'
AND type!='Rod' AND type!='Staff'
AND type!='Symbol' AND type!='Waist'
AND type!='Wand' AND type!='Wondrous Item'
AND type!='Alchemical Item' AND type!='Elixir'
AND type!='Reagent' AND type!='Whetstone'
AND type!='Other Consumable' AND type!='Companion'
AND type!='Mount' AND (type!='Armor' OR (false ))
AND (type!='Weapon' OR (false ))
ORDER BY type ASC, itemlevel ASC, name ASC
</code></pre>
<p>It seems to work well enough, but it's also not particularly high traffic (a few hundred hits a day or so), and I wonder if it would be worth the effort to try and optimize the queries to remove redundancies and such.</p>

<p>I'm writing an inner loop that needs to place <code>struct</code>s in contiguous storage. I don't know how many of these <code>struct</code>s there will be ahead of time. My problem is that STL's <code>vector</code> initializes its values to 0, so no matter what I do, I incur the cost of the initialization plus the cost of setting the <code>struct</code>'s members to their values.</p>
<p>Is there any way to prevent the initialization, or is there an STL-like container out there with resizeable contiguous storage and uninitialized elements?</p>
<p>(I'm certain that this part of the code needs to be optimized, and I'm certain that the initialization is a significant cost.)</p>
<p>Also, see my comments below for a clarification about when the initialization occurs.</p>
<p>SOME CODE:</p>
<pre><code>void GetsCalledALot(int* data1, int* data2, int count) {
int mvSize = memberVector.size()
memberVector.resize(mvSize + count); // causes 0-initialization
for (int i = 0; i < count; ++i) {
memberVector[mvSize + i].d1 = data1[i];
memberVector[mvSize + i].d2 = data2[i];
}
}
</code></pre>

<p>My development server (CentOS 5) is running Subversion 1.4.2, and I wish to upgrade it to 1.5. I have read in various blogs and documents scattered around the web that this may be done by using RPMForge. I have followed the instructions found on <a href="http://wiki.centos.org/AdditionalResources/Repositories/RPMForge?action=show&redirect=Repositories%2FRPMForge" rel="nofollow noreferrer">CentOS Wiki</a>, including installing yum-priorities and setting my priorities as indicated (1 and 2 for core repo sources, and 20 for RPMForge).</p>
<p>However, when I attempt to run:</p>
<pre><code>$ yum info subversion
</code></pre>
<p>the version number given to me is still 1.4.2, with a status of Installed. My other option at this point is compiling from source, but I would like to find a package-managed solution for ease of future upgrades.</p>
<p>Any thoughts?</p>

<p>So if I'm using branches that are remote (tracked) branches, and I want to get the lastest, I'm still unclear if I should be doing <code>git pull</code> or <code>git rebase</code>. I thought I had read that doing <code>git rebase</code> when working on a branch with other users, it can screw them up when they pull or rebase. Is that true? Should we all be using <code>git pull</code>?</p>

<p>I have a query that I would like to filter in different ways at different times. The way I have done this right now by placing parameters in the criteria field of the relevant query fields, however there are many cases in which I do not want to filter on a given field but only on the other fields. Is there any way in which a wildcard of some sort can be passed to the criteria parameter so that I can bypass the filtering for that particular call of the query?</p>

<p>I have a flash app (SWF) running Flash 8 embedded in an HTML page. How do I get flash to reload the parent HTML page it is embedded in? I've tried using ExternalInterface to call a JavaScript function to reload the page but that doesn't seem to work.
</p>

<p>I've got a situation where I have a DLL I'm creating that uses another third party DLL, but I would prefer to be able to build the third party DLL into my DLL instead of having to keep them both together if possible.</p>
<p>This with is C# and .NET 3.5.</p>
<p>The way I would like to do this is by storing the third party DLL as an embedded resource which I then place in the appropriate place during execution of the first DLL.</p>
<p>The way I originally planned to do this is by writing code to put the third party DLL in the location specified by <code>System.Reflection.Assembly.GetExecutingAssembly().Location.ToString()</code>
minus the last <code>/nameOfMyAssembly.dll</code>. I can successfully save the third party <code>.DLL</code> in this location (which ends up being </p>
<blockquote>
<p>C:\Documents and Settings\myUserName\Local Settings\Application
Data\assembly\dl3\KXPPAX6Y.ZCY\A1MZ1499.1TR\e0115d44\91bb86eb_fe18c901 </p>
</blockquote>
<p>), but when I get to the part of my code requiring this DLL, it can't find it.</p>
<p>Does anybody have any idea as to what I need to be doing differently?</p>

<p>I'm building a widget, and I've been using iframes to present content within it. At some point, I might start serving third party HTML and JS, so I thought iframes would be a good idea. </p>
<p>It does make the widget javascript a little more complicated, and I'm concerned that this might not be the best implementation.</p>
<p>Do you have any advice? It would be a huge help to hear what other people think about iframes.</p>

<p>I have CSV data loaded into a multidimensional array. In this way each "row" is a record and each "column" contains the same type of data. I am using the function below to load my CSV file.</p>
<pre><code>function f_parse_csv($file, $longest, $delimiter)
{
$mdarray = array();
$file = fopen($file, "r");
while ($line = fgetcsv($file, $longest, $delimiter))
{
array_push($mdarray, $line);
}
fclose($file);
return $mdarray;
}
</code></pre>
<p>I need to be able to specify a column to sort so that it rearranges the rows. One of the columns contains date information in the format of <code>Y-m-d H:i:s</code> and I would like to be able to sort with the most recent date being the first row.</p>

<p>Pretty basic question, I'm trying to write a regex in Vim to match any phrase starting with <code>"abc "</code> directly followed by anything other than <code>"defg"</code>. </p>
<p>I've used <code>"[^defg]"</code> to match any single character other than d, e, f or g.</p>
<p>My first instinct was to try <code>/abc [^\(defg\)]</code> or <code>/abc [^\<defg\>]</code> but neither one of those works.</p>

<p>For example:</p>
<pre><code>use constant X => 1;
my %x = (X => 'X');
</code></pre>
<p>The above code will create a hash with "X" as key and not 1 as key. Whereas, I want to use the value of constant X as key.</p>

<p>What are some good package naming conventions for domain specific object models. For example, say you have a <strong>Person.java</strong> POJO, would you put it in a <strong>mydomain.model</strong> or <strong>mydomain.entity</strong> or <strong>mydomain.om</strong> (object model) package. The idea is to separate the MVC model objects from the domain object model. Our MVC based application has a <strong>model</strong> package that contains behavior but using that package to contain our domain object model seems inappropriate and potentially confusing. </p>

<p>I'd like to make status icons for a C# WinForms TreeList control. The statuses are combinations of other statuses (eg. a user node might be inactive or banned or inactive and banned), and the status icon is comprised of non-overlapping, smaller glyphs. </p>
<p>I'd really like to avoid having to hand-generate all the possibly permutations of status icons if I can avoid it. </p>
<p>Is it possible to create an image list (or just a bunch of bitmap resources or something) that I can use to generate the ImageList programmatically?</p>
<p>I'm poking around the System.Drawing classes and nothing's jumping out at me. Also, I'm stuck with .Net 2.0.</p>

<p>I need to create a nice installer for a Mac application. I want it to be a disk image (DMG), with a predefined size, layout and background image.</p>
<p>I need to do this programmatically in a script, to be integrated in an existing build system (more of a pack system really, since it only create installers. The builds are done separately). </p>
<p>I already have the DMG creation done using "hdiutil", what I haven't found out yet is how to make an icon layout and specify a background bitmap.</p>

<p>The standard answer is that it's useful when you only need to write a few lines of code ...</p>
<p>I have both languages integrated inside of Eclipse. Because Eclipse handles the compiling, interpreting, running etc. both "run" exactly the same.</p>
<p>The Eclipse IDE for both is similar - instant "compilation", intellisense etc. Both allow the use of the Debug perspective.</p>
<p>If I want to test a few lines of Java, I don't have to create a whole new Java project - I just use the <a href="http://www.eclipsezone.com/eclipse/forums/t61137.html" rel="noreferrer">Scrapbook</a> feature inside Eclipse which which allows me to <em>"execute Java expressions without having to create a new Java program. This is a neat way to quickly test an existing class or evaluate a code snippet"</em>. </p>
<p>Jython allows the use of the Java libraries - but then so (by definition) does Java!</p>
<p>So what other benefits does Jython offer?</p>

<p>I am using Oracle 9 and JDBC and would like to encyrpt a clob as it is inserted into the DB. Ideally I'd like to be able to just insert the plaintext and have it encrypted by a stored procedure:</p>
<pre><code>String SQL = "INSERT INTO table (ID, VALUE) values (?, encrypt(?))";
PreparedStatement ps = connection.prepareStatement(SQL);
ps.setInt(id);
ps.setString(plaintext);
ps.executeUpdate();
</code></pre>
<p>The plaintext is not expected to exceed 4000 characters but encrypting makes text longer. Our current approach to encryption uses dbms_obfuscation_toolkit.DESEncrypt() but we only process varchars. Will the following work?</p>
<pre><code>FUNCTION encrypt(p_clob IN CLOB) RETURN CLOB
IS
encrypted_string CLOB;
v_string CLOB;
BEGIN
dbms_lob.createtemporary(encrypted_string, TRUE);
v_string := p_clob;
dbms_obfuscation_toolkit.DESEncrypt(
input_string => v_string,
key_string => key_string,
encrypted_string => encrypted_string );
RETURN UTL_RAW.CAST_TO_RAW(encrypted_string);
END;
</code></pre>
<p>I'm confused about the temporary clob; do I need to close it? Or am I totally off-track?</p>
<p>Edit:
The purpose of the obfuscation is to prevent trivial access to the data. My other purpose is to obfuscate clobs in the same way that we are already obfuscating the varchar columns. The oracle sample code does not deal with clobs which is where my specific problem lies; encrypting varchars (smaller than 2000 chars) is straightforward.</p>

<p>Assuming a map where you want to preserve existing entries. 20% of the time, the entry you are inserting is new data. Is there an advantage to doing std::map::find then std::map::insert using that returned iterator? Or is it quicker to attempt the insert and then act based on whether or not the iterator indicates the record was or was not inserted?</p>

<p>Someone told me about a C++ style difference in their team. I have my own viewpoint on the subject, but I would be interested by <em>pros</em> and <em>cons</em> coming from everyone.</p>
<p>So, in case you have a class property you want to expose via two getters, one read/write, and the other, readonly (i.e. there is no set method). There are at least two ways of doing it:</p>
<pre><code>class T ;
class MethodA
{
public :
const T & get() const ;
T & get() ;
// etc.
} ;
class MethodB
{
public :
const T & getAsConst() const ;
T & get() ;
// etc.
} ;
</code></pre>
<p>What would be the pros and the cons of each method?</p>
<p>I am interested more by C++ technical/semantic reasons, but style reasons are welcome, too.</p>
<p>Note that <code>MethodB</code> has one major technical drawback (hint: in generic code).</p>

<p>What I am trying to achieve is a form that has a button on it that causes the Form to 'drop-down' and become larger, displaying more information. My current attempt is this:</p>
<pre><code>private void btnExpand_Click(object sender, EventArgs e)
{
if (btnExpand.Text == ">")
{
btnExpand.Text = "<";
_expanded = true;
this.MinimumSize = new Size(1, 300);
this.MaximumSize = new Size(int.MaxValue, 300);
}
else
{
btnExpand.Text = ">";
_expanded = false;
this.MinimumSize = new Size(1, 104);
this.MaximumSize = new Size(int.MaxValue, 104);
}
}
</code></pre>
<p>Which works great! Except for one small detail... Note that the width values are supposed to be able to go from 1 to int.MaxValue? Well, in practice, they go from this.Width to int.MaxValue, ie. you can make the form larger, but never smaller again. I'm at a loss for why this would occur. Anyone have any ideas?</p>
<p>For the record: I've also tried a Form.Resize handler that set the Height of the form to the same value depending on whatever the boolean _expanded was set to, but I ended up with the same side effect.</p>
<p>PS: I'm using .NET 3.5 in Visual Studio 2008. Other solutions are welcome, but this was my thoughts on how it "should" be done and how I attempted to do it.</p>
<p>Edit: Seems the code works, as per the accepted answers response. If anyone else has troubles with this particular problem, check the AutoSize property of your form, it should be FALSE, not TRUE. (This is the default, but I'd switched it on as I was using the form and a label with autosize also on for displaying debugging info earlier)</p>

<p>In a recent question on stubbing, many answers suggested C# interfaces or delegates for implementing stubs, but <a href="https://stackoverflow.com/questions/43711/whats-a-good-way-to-overwrite-datetimenow-during-testing#43718">one answer</a> suggested using conditional compilation, retaining static binding in the production code. This answer was modded -2 at the time of reading, so at least 2 people really thought this was a <em>wrong</em> answer. Perhaps misuse of DEBUG was the reason, or perhaps use of fixed value instead of more extensive validation. But I can't help wondering:</p>
<p>Is the use of conditional compilation an inappropriate technique for implementing unit test stubs? Sometimes? Always?</p>
<p>Thanks.</p>
<p><strong>Edit-add:</strong> I'd like to add an example as a though experiment:</p>
<pre><code>class Foo {
public Foo() { .. }
private DateTime Now {
get {
#if UNITTEST_Foo
return Stub_DateTime.Now;
#else
return DateTime.Now;
#endif
}
}
// .. rest of Foo members
}
</code></pre>
<p>comparing to</p>
<pre><code>interface IDateTimeStrategy {
DateTime Now { get; }
}
class ProductionDateTimeStrategy : IDateTimeStrategy {
public DateTime Now { get { return DateTime.Now; } }
}
class Foo {
public Foo() : Foo(new ProductionDateTimeStrategy()) {}
public Foo(IDateTimeStrategy s) { datetimeStrategy = s; .. }
private IDateTime_Strategy datetimeStrategy;
private DateTime Now { get { return datetimeStrategy.Now; } }
}
</code></pre>
<p>Which allows the outgoing dependency on "DateTime.Now" to be stubbed through a C# interface. However, we've now added a dynamic dispatch call where static would suffice, the object is larger even in the production version, and we've added a new failure path for Foo's constructor (allocation can fail). </p>
<p>Am I worrying about nothing here? Thanks for the feedback so far!</p>

<p>I am trying to do 'rake db:migrate' and getting the error message 'no such file to load -- openssl'. Both 'openssl' and 'openssl-devel' packages are installed. Others on Debian or Ubuntu seem to be able to get rid of this by installing 'libopenssl-ruby', which is not available for RedHat. Has anybody run into this and have a solution for it?</p>

<p>I'm using freemarker, SiteMesh and Spring framework.
For the pages I use ${requestContext.getMessage()} to get the message from message.properties. But for the decorators this doesn't work. How should I do to get the internationalization working for sitemesh?</p>

<p>Is there a way via System.Reflection, System.Diagnostics or other to get a reference to the actual instance that is calling a static method without passing it in to the method itself?</p>
<p>For example, something along these lines</p>
<pre><code>class A
{
public void DoSomething()
{
StaticClass.ExecuteMethod();
}
}
class B
{
public void DoSomething()
{
SomeOtherClass.ExecuteMethod();
}
}
public class SomeOtherClass
{
public static void ExecuteMethod()
{
// Returns an instance of A if called from class A
// or an instance of B if called from class B.
object caller = getCallingInstance();
}
}
</code></pre>
<p>I can get the type using <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.stacktrace.getframes.aspx" rel="noreferrer">System.Diagnostics.StackTrace.GetFrames</a>, but is there a way to get a reference to the actual instance?</p>
<p>I am aware of the issues with reflection and performance, as well as static to static calls, and that this is generally, perhaps even almost univerally, not the right way to approach this. Part of the reason of this question is I was curious if it was doable; we are currently passing the instance in.</p>
<pre><code>ExecuteMethod(instance)
</code></pre>
<p>And I just wondered if this was possible and still being able to access the instance.</p>
<pre><code>ExecuteMethod()
</code></pre>
<hr>
<p>@Steve Cooper:
I hadn't considered extension methods. Some variation of that might work.</p>

<p>The "N+1 selects problem" is generally stated as a problem in Object-Relational mapping (ORM) discussions, and I understand that it has something to do with having to make a lot of database queries for something that seems simple in the object world.</p>
<p>Does anybody have a more detailed explanation of the problem?</p>

<p>I am using the <strong>AjaxControlToolkit</strong> in VS2005, and it works fine. I do have some issues though, when I go to some pages I have, then click back, I get this JavaScript error:</p>
<blockquote>
<p>'AjaxControlToolkit' is undefined</p>
</blockquote>
<p>I have searched MSDN forums, and google, and tried many of the solutions, but none have worked. I have tried, <code>EnablePartialRendering="true",</code> and others. Short of rewriting everything and changing the workflow of my application, is there any way to find the root cause of this, or fix it?

<p>When dealing with mobile clients it is very common to have multisecond delays during the transmission of HTTP requests. If you are serving pages or services out of a prefork Apache the child processes will be tied up for seconds serving a single mobile client, even if your app server logic is done in 5ms. I am looking for a HTTP server, balancer or proxy server that supports the following:</p>
<ol>
<li><p>A request arrives to the proxy. The proxy starts buffering in RAM or in disk the request, including headers and POST/PUT bodies. The proxy DOES NOT open a connection to the backend server. This is probably the most important part.</p></li>
<li><p>The proxy server stops buffering the request when:</p>
<ul>
<li>A size limit has been reached (say, 4KB), or</li>
<li>The request has been received completely, headers and body</li>
</ul></li>
<li><p>Only now, with (part of) the request in memory, a connection is opened to the backend and the request is relayed.</p></li>
<li><p>The backend sends back the response. Again the proxy server starts buffering it immediately (up to a more generous size, say 64KB.) </p></li>
<li><p>Since the proxy has a big enough buffer the backend response is stored completely in the proxy server in a matter of miliseconds, and the backend process/thread is free to process more requests. The backend connection is immediately closed.</p></li>
<li><p>The proxy sends back the response to the mobile client, as fast or as slow as it is capable of, without having a connection to the backend tying up resources.</p></li>
</ol>
<p>I am fairly sure you can do 4-6 with Squid, and nginx appears to support 1-3 (and looks like fairly unique in this respect). My question is: is there any proxy server that empathizes these buffering and not-opening-connections-until-ready capabilities? Maybe there is just a bit of Apache config-fu that makes this buffering behaviour trivial? Any of them that it is not a dinosaur like Squid and that supports a lean single-process, asynchronous, event-based execution model?</p>
<p>(Siderant: I would be using nginx but it doesn't support chunked POST bodies, making it useless for serving stuff to mobile clients. Yes cheap 50$ handsets love chunked POSTs... sigh)</p>

<p>Ok, here's the breakdown of my project: I have a web project with a "Scripts" subfolder. That folder contains a few javascript files and a copy of JSMin.exe along with a batch file that runs the JSMin.exe on a few of the files. I tried to set up a post build step of 'call "$(ProjectDir)Scripts\jsmin.bat"'. When I perform the build, the batch file is always "exited with code 1." This happens going through Visual Studio or through the msbuild command line. I can run the batch file manually from the Scripts folder and it seems to work as expected, so I'm not sure what the issue here is. The $(ProjectDir)Scripts\jsmin.bat call is in quotes because $(ProjectDir) could have spaces (and in fact does on my machine). I'm not sure what to do at this point. I've tried removing the contents of the batch file as the post build step but that doesn't seem to work either.</p>
<p>Ideally I would like to solve this problem through the post or pre-build steps so that the build manager won't have to go through an extra step when deploying code.</p>
<p>Thanks!</p>

<p>If I've got a time_t value from <code>gettimeofday()</code> or compatible in a Unix environment (e.g., Linux, BSD), is there a compact algorithm available that would be able to tell me the corresponding week number within the month?</p>
<p>Ideally the return value would work in similar to the way <code>%W</code> behaves in <code>strftime()</code> , except giving the week within the month rather than the week within the year.</p>
<p>I think Java has a <code>W</code> formatting token that does something more or less like what I'm asking.</p>
<hr>
<p>[Everything below written after answers were posted by David Nehme, Branan, and Sparr.]</p>
<p>I realized that to return this result in a similar way to <code>%W</code>, we want to count the number of Mondays that have occurred in the month so far. If that number is zero, then 0 should be returned.</p>
<p>Thanks to David Nehme and Branan in particular for their solutions which started things on the right track. The bit of code returning [using Branan's variable names] <code>((ts->mday - 1) / 7)</code> tells the number of complete weeks that have occurred before the current day.</p>
<p>However, if we're counting the number of Mondays that have occurred so far, then we want to count the number of integral weeks, including today, then consider if the fractional week left over also contains any Mondays.</p>
<p>To figure out whether the fractional week left after taking out the whole weeks contains a Monday, we need to consider <code>ts->mday % 7</code> and compare it to the day of the week, <code>ts->wday</code>. This is easy to see if you write out the combinations, but if we insure the day is not Sunday (<code>wday > 0</code>), then anytime <code>ts->wday <= (ts->mday % 7)</code> we need to increment the count of Mondays by 1. This comes from considering the number of days since the start of the month, and whether, based on the current day of the week within the the first fractional week, the fractional week contains a Monday.</p>
<p>So I would rewrite Branan's return statement as follows:</p>
<p><code>return (ts->tm_mday / 7) + ((ts->tm_wday > 0) && (ts->tm_wday <= (ts->tm_mday % 7)));</code></p>

<p>Does anyone know a keyboard shortcut to close all tabs except for the current one in Visual Studio? And while we're at it, the shortcut for closing all tabs? Is there a Resharper option for this? I've looked in the past and have never been able to find it. </p>

<p>Suppose I have a collection (be it an array, generic List, or whatever is the <strong>fastest</strong> solution to this problem) of a certain class, let's call it <code>ClassFoo</code>:</p>
<pre><code>class ClassFoo
{
public string word;
public float score;
//... etc ...
}
</code></pre>
<p>Assume there's going to be like 50.000 items in the collection, all in memory.
Now I want to obtain as fast as possible all the instances in the collection that obey a condition on its bar member, for example like this:</p>
<pre><code>List<ClassFoo> result = new List<ClassFoo>();
foreach (ClassFoo cf in collection)
{
if (cf.word.StartsWith(query) || cf.word.EndsWith(query))
result.Add(cf);
}
</code></pre>
<p>How do I get the results as fast as possible? Should I consider some advanced indexing techniques and datastructures?</p>
<p>The application domain for this problem is an autocompleter, that gets a query and gives a collection of suggestions as a result. Assume that the condition doesn't get any more complex than this. Assume also that there's going to be a lot of searches.</p>

<p>We want to store our overridden build targets in an external file and include that targets file in the TFSBuild.proj. We have a core set steps that happens and would like to get those additional steps by simply adding the import line to the TFSBuild.proj created by the wizard. </p>
<pre><code><Import Project="$(SolutionRoot)/libs/my.team.build/my.team.build.targets"/>
</code></pre>
<p>We cannot have an import on any file in the <code>$(SolutionRoot)</code> because at the time the Import statement is validated, the source has not be fetched from the repository. It looks like TFS is pulling down the <code>TFSBuild.proj</code> first without any other files.</p>
<p>Even if we add a conditional import, the version in source control will not be imported if present. The previous version, already present on disk will be imported. </p>
<p>We can give up storing those build targets with our source, but it is the first dependency to move out of our source tree so we are reluctant to do it.</p>
<p>Is there a way to either:</p>
<ol>
<li>Tell Team Build to pull down a few more files so those <code>Import</code> statements evaluate correctly?</li>
<li>Override those Team Build targets like <code>AfterCompile</code> in a manner besides the <code>Import</code>?</li>
<li>Ultimately run build targets in Team Build that are kept under the source it's trying to build?</li>
</ol>
