How can I initialize a map of String and Int (VC++.NET 2005) As of now you cannot create a map containing managed types.

  Hi, I have a C++ class for accessing images from a DirectShow-compatible camera. For this I get a pixelbuffer that is actually a one-dimensional array of characters.

• Deluxdecals Multithreading

  Is it possible for a master thread to force abortion of pending IO in a slave thread, as with signals on Posix. Win32 only, no .net bullshit please. Thanks, - NK The esiest way to acomplish this with the Win-32 API is to switch from using blocking I/O to using asynchronus I/O with notification via Win-32 events, then block waiting for the event rather than inside the I/O routine. So, in your I/O thread crea ...Show All

• recruz Is PGO available in the standard edition of VS2005?

  Aloha! A few years back I bought the standard edition of Visual Studio.NET and was disappointed to see that it didn't feature the optimizing C compiler - that was reserved for the professional edition, and made a speed difference of a factor of 2 or more. Now, I see that PGO will not be supported in the express products :-(. I realize that PGO is not going to make a huge difference, but an additional 20% aer always appreciated in board game prog ...Show All
