Ok, what hell is wrong here? I'm calling ::AllocConsole(), which doesn't report an error, then I'm calling ::SetConsoleTitle("title") which returns non-zero as well, and finally I'm calling ::GetStdHandle(STD_OUTPUT_HANDLE) which returns a valid handle (!=INVALID_HANDLE_VALUE). Why then printing to console or calling ::SetConsoleScreenBufferSize() fail with error ERROR_INVALID_HANDLE??

Not sure about your specific question, but I use this to create a console and use std::cout and such for printing to it.

#ifdef _DEBUG
if (AllocConsole())
{
freopen ("CONIN$", "rb", stdin);
freopen ("CONOUT$", "wb", stdout);
freopen ("CONOUT$", "wb", stderr);
}
#endif

Alright solved. Just using ::CreateConsoleScreenBuffer and friends.

Worked like a charm for me. Ratings++.
