求大神指导,感激不尽。
我按书上给的源程序编译时却出现了错误。怎么了?下面是源代码:
#include <windows.h>
LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR szCmdLine, int iCmdShow)

HWND hwnd ;
MSG msg ;

wndclass.lpfnWndProc = WndProc ;
wndclass.cbClsExtra = 0 ;

wndclass.lpszClassName= szAppName ;
if (!RegisterClass (&wndclass))
{

szAppName, MB_ICONERROR) ;
return 0 ;
}

while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage (&msg) ;

}
return msg.wParam ;
}
