    c# .net visual-studio-2010 linq visual-studio-2012
    Somehow following code doesn’t compile in VS2010 but compiles in VS2012 without changes. The problematic line in VS2010 is names.Select(foo.GetName)error CS1928: ‘string[]’ does not contain a definition for ‘Select’ and the best extension method overload ‘System.Linq.Enumerable.Select<TSource,TResult>(System.Collections.Generic.IEnumerable<TSource>, System.Func<TSource,TResult>)’ has some invalid arguments.using System; using System.Linq;namespace ConsoleApplication1 {class Pro

    .net timer
    Note that I’m asking about something that will call a callback function more often than once every 15 ms using something like System.Threading.Timer. I’m not asking about how to accurately time a piece of code using something like System.Diagnostics.Stopwatch or even QueryPerformanceCounter.Also, I’ve read the related questions:http://stackoverflow.com/questions/448761/accurate-windows-timer-system-timers-timer-is-limited-to-15-msechttp://stackoverflow.com/questions/163022/high-resolution-timer

    c# .net out-of-memory
    Why does this:class OutOfMemoryTest02 {static void Main(){string value = new string(‘a’, int.MaxValue);} }Throw the exception; but this wont:class OutOfMemoryTest {private static void Main(){Int64 i = 0;ArrayList l = new ArrayList();while (true){l.Add(new String(‘c’, 1024));i++;}} }Whats the difference?

    .net winforms nunit-2.5
    First of all, sorry for my english since it’s not my native language.Problem was happened in my .NET Windows Forms Application and reproduced only on Virtaul PC Windows 7 (x64) for some reasons. I faced with Win32Exception in one place of my application when resizing main application form containing a lot of custom controls, including two stacked to each other tabcontrols etc… Exception’s message was “Error creating window handle”. Spending some time I found solution for that problem on Micro

    c# .net winapi watin screenshot
    I’m currently working with WatiN, and finding it to be a great web browsing automation tool. However, as of the last release, it’s screen capturing functionality seems to be lacking. I’ve come up with a workable solution for capturing screenshots from the screen (independently generating code similar to this StackOverflow question) in addition to some code by Charles Petzold. Unfortunately, there is a missing component: Where is the actual window?WatiN conveniently provides the browser’s hWnd
