新来啊!!没有那个什么币,希望能帮助我一下````

下面的这个是我前几天学的,能通过,#include <windows.h> //必须的头文件

LRESULT CALLBACK WinProc(HWND,UINT,WPARAM,LPARAM);//回调函数(过程)原型
int WINAPI WinMain(
HINSTANCE hInstance, //实例句柄
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow
)
{
WNDCLASS wndcls; //WNDCLASS结构
wndcls.style=CS_HREDRAW |CS_VREDRAW;
wndcls.cbClsExtra=0;
wndcls.cbWndExtra=0;
wndcls.lpfnWndProc=WinProc; //回调函数(过程)
wndcls.lpszClassName="FirstMain"; //窗口类名
wndcls.lpszMenuName=NULL;
wndcls.hbrBackground=(HBRUSH) GetStockObject(WHITE_BRUSH);
wndcls.hIcon=LoadIcon(NULL,IDI_WINLOGO);
wndcls.hCursor=LoadCursor(NULL,IDC_ARROW);
wndcls.hInstance=hInstance; //实例句柄
RegisterClass(&wndcls); //注册
HWND hwnd; //创建父窗口句柄
hwnd=CreateWindowEx(
0,"FirstMain","窗口标题",
WS_TILEDWINDOW, //正常显示状态
200,200,300,200,
NULL,NULL,hInstance,NULL);
ShowWindow(hwnd,SW_SHOWNORMAL); //句柄,显示状态
UpdateWindow(hwnd); //句柄
MSG msg;
while(GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg); //键盘消息转换为字符
DispatchMessage(&msg); //返回msg给回调函数(过程)
}
return 0;
}
LRESULT CALLBACK WinProc(
HWND hwnd, // 当前句柄
UINT msg, // 当前MSG消息
WPARAM wParam,
LPARAM lParam
)
{
switch(msg)
{
case WM_LBUTTONDOWN:
MessageBox(hwnd,"mouse clicked","消息框",0);
HDC hdc;
hdc=GetDC(hwnd);
TextOut(hdc,0,0,"鼠标单击",strlen("鼠标单击"));
ReleaseDC(hwnd,hdc);
break;
case WM_CLOSE:
if(IDYES==MessageBox(hwnd,"是否结束?","message",MB_YESNO))
{
DestroyWindow(hwnd);
}
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd,msg,wParam,lParam); //缺省必须使用
}
return 0;
}

今天自己通宵做了另外一个,一个自动关机的MFC程序,但是能编译,不能运行,但是没有窗口显示,在进程中有,不知道怎么回事!!!!!求大神解答!!!!
