• Visual C# List<T>.Insert is very slow?

  I have been writing a class that uses the List<T> class and noticed a huge performance decrease when using the List<T>.Insert method to insert my elements in the correct position as opposed to just adding them to the end of the list. The collection is about 200000 elements big. I tested this by creating a new project that creates a new List<int> and adds 200000. After that I add another 100000 by using the List<T>.A ...Show All

• Visual C++ Compiling fftw - what flags should I use for best performance?

  Greetings, I have compiled the fftw fft package from www.fftw.org  using the Visual C++ 2005 Express Edition beta 2 but I can`t seem to find a good choice of flags for optimizing the code. As I run the benchmark code that comes with the package I get slower performance with msvc than if I compile with gcc 3.3.3 under cygwin which seems strange because I usually see the opposite behavior. Has anyone else tried to compile this package with th ...Show All

• SQL Server Label Reports

  Are there any facilities in reporting services (2005 or 2000) for doing mailing label reports. We used to use these a lot in MS Access but now we are using Reporting Services for reports and it doesn't seem like there are facilities for labels. I am guessing it could be arranged with some clever lists or tables but not so nice as just picking the type of labels and it does all the formatting for you. Any info would be much appreciated.

• Game Technologies: DirectX, XNA, XACT, etc. DirectInput or WndProc?

  I've noticed the in the August SDK (and previous ones) that all of the samples use a WndProc function to handle keyboard and mouse input. I assume there is a good reason that DirectInput is not being used. Could someone please enlighten me as to what it is....
