Change Thread Name in MFC
-
Hi, is it possible to change the Threadname of a Thread that was created with "AfxBeginThread()"? In C# it is quite easy, but i couldn't find out a method for C++/MFC. It would be nice to read the correct threadname in the debuggerwindow. Right now it always tells me: "The Thread 'Win32 Thread' finished with code 0 (0x0).". Thanks, Snow
