How to write to the Output window in Visual Studio?

Question

Which function should I use to output text to the \"Output\" window in Visual Studio?

I tried printf() but it doesn\'t show up.

Answer 1

OutputDebugString function will do it.

example code

    void CClass::Output(const char* szFormat, ...)
{
    char szBuff[1024];
    va_list arg;
    va_start(arg, szFormat);
    _vsnprintf(szBuff, sizeof(szBuff), szFormat, arg);
    va_end(arg);

    OutputDebugString(szBuff);
}
