Win32 App with a separate Console box
Author
How can i create a console app to be separate from the main win32 app? In my case its a game engine. I already have the windows code working... but how do i get it to open a separate console to put text into... in my case it is for debug purposes.
You can create a console window for a Windows application by calling AllocConsole(). If you want to use it with the standard file streams you'll also need to reopen the streams. Ex:
AllocConsole();freopen("conin$","r",stdin);freopen("conout$","w",stdout);freopen("conout$","w",stderr);
here some code I came along a long time ago and it works great for that, its alot move than what was posted above but its copy/paste workable =p
int hConHandle; long lStdHandle; CONSOLE_SCREEN_BUFFER_INFO coninfo; FILE *fp; AllocConsole(); SetConsoleTitle("Server"); // set the screen buffer to be big enough to let us scroll text GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &coninfo); coninfo.dwSize.Y = MAX_CONSOLE_LINES; SetConsoleScreenBufferSize(GetStdHandle(STD_OUTPUT_HANDLE), coninfo.dwSize); // redirect unbuffered STDOUT to the console lStdHandle = (long)GetStdHandle(STD_OUTPUT_HANDLE); hConHandle = _open_osfhandle(lStdHandle, _O_TEXT); fp = _fdopen( hConHandle, "w" ); *stdout = *fp; setvbuf( stdout, NULL, _IONBF, 0 ); // redirect unbuffered STDIN to the console lStdHandle = (long)GetStdHandle(STD_INPUT_HANDLE); hConHandle = _open_osfhandle(lStdHandle, _O_TEXT); fp = _fdopen( hConHandle, "r" ); *stdin = *fp; setvbuf( stdin, NULL, _IONBF, 0 ); // redirect unbuffered STDERR to the console lStdHandle = (long)GetStdHandle(STD_ERROR_HANDLE); hConHandle = _open_osfhandle(lStdHandle, _O_TEXT); fp = _fdopen( hConHandle, "w" ); *stderr = *fp; setvbuf( stderr, NULL, _IONBF, 0 ); // make cout, wcout, cin, wcin, wcerr, cerr, wclog and clog point to console as well ios::sync_with_stdio(false); return;This topic is closed to new replies.
