win32 application 工程下的简单图形的程序执行不出来结果
win32 application 工程下的简单图形的程序执行不出来结果,编译已经通过,但运行的时候什么也没出来,另外在网上查了一下也没查到相关的问题解决,代码如下:#include"windows.h"
#include"stdlib.h"
#include"string.h"
long WINAPI WndProc(HWND hWnd,UINT iMessage,UINT wParam,LONG lParam);

WndClass.cbClsExtra=0;
WndClass.cbWndExtra=0;

编译是可以通过的,平台是微软的那个VC++6.0,小弟刚刚开始学VC,请各位高手们指教啊.
