Create the Header File

The header file contains definitions and declarations required by the C-language source file which are incorporated into the source code by an #include directive. Name the file GENERIC.H and make sure it looks like this:

#define IDM_ABOUT 100

int PASCAL WinMain (HANDLE, HANDLE, LPSTR, int);

BOOL InitApplication (HANDLE);

BOOL InitInstance (HANDLE, int);

long FAR PASCAL MainWndProc (HWND, unsigned, WORD, LONG);

BOOL FAR PASCAL About (HWND, unsigned, WORD, LONG);
