vc++ exe窗口无法弹出
vc++ 工程文件为WIN32 APPLICATION（空）
然后添加头文件WinMain
代码如下： //编译通过 运行也没提示错误 就是没有EXE窗口弹出
//高手解答下为什么?
#include<windows.h>
#include<stdio.h>
LRESULT CALLBACK WinSunProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
);
int WINAPI WinMain(
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lprevInstance,
int nCmdshow
)
{
WNDCLASS wndcls;
wndcls.cbClsExtra=0;
wndcls.cbWndExtra=0;
wndcls.hbrBackground=(HBRUSH)GetStockObject(BLACK_BRUSH);
wndcls.hCursor=LoadCursor(NULL,IDC_CROSS);
wndcls.hIcon=LoadIcon(NULL,IDI_ERROR);
wndcls.hInstance=hInstance;
wndcls.lpfnWndProc=WinSunProc;
wndcls.lpszClassName="sunxing2006";
wndcls.lpszMenuName=NULL;
wndcls.style=CS_HREDRAW | CS_VREDRAW;
RegisterClass(&wndcls);
//创建窗口。定义一个变量用来保存创建窗口后返回的句柄
HWND hwnd;
static TCHAR szName[]= "sunxn.org";
hwnd=CreateWindow(szName,"http://www.sunxn.org",
WS_OVERLAPPEDWINDOW,0,0,600,400,NULL,NULL,hInstance,NULL);
//显示刷新窗口
ShowWindow(hwnd,SW_SHOWNORMAL);
UpdateWindow(hwnd);
//定义消息结构体 开始消息循环
MSG msg;
while(GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
getchar();
return msg.wParam;
}
//编写窗口过程函数
LRESULT CALLBACK WinSunProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
)
{
switch(uMsg)
{case WM_CHAR:
char szChar[20];
sprintf(szChar,"char code is %d",wParam);
MessageBox(hwnd,szChar,"char",0);
break;
case WM_LBUTTONDOWN:
MessageBox(hwnd,"mouse clicked","message",0);
HDC hdc;
hdc=GetDC(hwnd);
TextOut(hdc,0,50,"程序员之家",strlen("程序员之家"));
ReleaseDC(hwnd,hdc);
break;
case WM_PAINT:
HDC hDc;
PAINTSTRUCT ps;
hDc=BeginPaint(hwnd,&ps);
TextOut(hDc,0,0,"http://www,sunxin,org",strlen("http://www,sunxin,org"));
EndPaint(hwnd,&ps);
break;
case WM_CLOSE:
if(IDYES==MessageBox(hwnd,"是否真的结束？","message",MB_YESNO))
{
DestroyWindow(hwnd);
}
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd,uMsg,wParam,lParam);
}
return 0;
}
[解决办法]
首先将
static TCHAR szName[]= "sunxn.org";
放在前面
然后改
wndcls.lpszClassName="sunxing2006";
为
wndcls.lpszClassName=szName;
---------------
RegisterClass与CreateWindow中的类名要一致
另外,我加了个memset(&wndcls,0,sizeof(WNDCLASS));
以防wndcls某些成员未初始化,我还将窗口起始点(0,0)改为(100,100),这个没关系
