Hello everyone!

When I start a "Win32 Project" with Microsoft's Visual C++ I can't
produce any output by using my "normal" C++ code that I would use in a
console application. First, I'm not sure if i place my code in the
right position, but I think I'm right as I don't get any error
messages and the comments by Visual C++ tell me the right place:

-----------------------------------------------------------------------------------

[...]

int APIENTRY _tWinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPTSTR lpCmdLine,
                     int nCmdShow)
{
    UNREFERENCED_PARAMETER(hPrevInstance);
    UNREFERENCED_PARAMETER(lpCmdLine);

// TODO: Place code here.

    cout << "This is a test!";

    [...]

}

[...]

-----------------------------------------------------------------------------------

When I compile this I just get an empty win32 window, and there's
nowhere written "This is a test!". I also included all necessary
header files, and didn't change nothing from the "main code" already
written by Visual C++, I just added "cout << "This is a test!" ".

Answer's too long to include here (although it's likely that others will
provide technically inaccurate and misleading short answers); see <url:
http://home.no.net/dubjai/win32apitut/01.pdf>. Please just ask in this
group if you have further questions regarding this specific issue. But
note: even though this is so common a newbie (and for that matter,
experienced dinosaur) a problem that it is in a way on-topic here,
please direct more specific Windows programming question to a Windows
programming group -- see the FAQ for group suggestions.

The referenced article also explains how you can use standard C++ 'main'.

Which you preferentially should.

Hth.,
