WINDOWS编程
#include "stdio.h"
#include "windows.h"
LRESULT CALLBACK wndproc(HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM lParam);
class win
{
public:
BOOL W_class(HINSTANCE hInstance);
BOOL create(HINSTANCE hInstance);

BOOL win::W_class(HINSTANCE hInstance)
{
WNDCLASS wdnclass;//设计窗口

wdnclass.lpfnWndProc=wndproc;//窗口指针很重要
wdnclass.cbClsExtra=0;//通常为0
