这是我编写的Hellowwindows程序，但有问题运行不了
#include<windows.h>
#include<string>
#include<stdio.h>
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
//入口函数
int APIENTRY WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR
lpCmdLine,int nCmdShow)
{
WNDCLASS wndclass;
HWND hwnd;
MSG msg;
wndclass.style = CS_HREDRAW|CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(NULL,IDI_APPLICATION);
wndclass.hCursor = LoadCursor(NULL,IDC_ARROW);
wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = "windows窗口创建";
if(! RegisterClass(&wndclass))
return FALSE;
hwnd = CreateWindow("window窗口创建","window窗口创建",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,CW_USEDEFAULT,
CW_USEDEFAULT,CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL);
ShowWindow(hwnd,nCmdShow);
UpdateWindow (hwnd);
while(GetMessage (&msg,NULL,0,0))
{
TranslateMessage (&msg);
DispatchMessage( &msg);
}
return msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
HDC hdc;
PAINTSTRUCT ps;
switch (message)
{
case WM_PAINT:
hdc = BeginPaint (hwnd,&ps);
TextOut(hdc,10,20,"哈哈,Windows编程创建的窗口!",28EndPaint (hwnd,&ps);
return 0;
case WM_DESTROY:
PostQuitMessage (0);
return 0;
}
return DefWindowProc (hwnd,message,wParam,lParam );
}
但是按下F7后出现了这个结果，再按下F5后没有窗口出现，但查看资源管理器时有后台的.exe程序运行，为什么？我用的是VS2010的C++，如果有高手，再详细说一下创建项目的步骤，谢谢了
