Hi Victor!

The problem was, as you stipulated, the 2 functions had to be moved to the top of WINMAIN. However this is the first time in all my examples that I had to do this. Furthermore, the example in book was coded as I showed it.

Concerning the DPtoLP(hdc,(LPPOINT) &rect,2); line, I am curious to see where the
LPRECT type is defined. I will try to look in Windows.h later. Let me know if it is elsewhere!


Ross:

I think you are trying to learn Windows programming before you have learned C and/or C++. Not an easy thing to do.

In C and C++ every function must be defined OR DECLARED before it is used. Perhaps your book contains declarations of these 2 functions before WinMain()? The declarations should look like this:

void Show (HWND hwnd, HDC hdc, int xText, int yText, int iMapMode,
		   TCHAR * szMapMode);

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM
lParam);

If you do this at the top, you can put the corresponding function definitions at the bottom.
