请看这个程序
#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 lpCmdLine,
int nCmdShow
)
{

win2007.cbClsExtra=0;
win2007.cbWndExtra=0;

while(GetMessage(&msg,NULL,0,0))
{

DispatchMessage(&msg);
}
return 0;
}
LRESULT CALLBACK WinSunProc
(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
)
{
switch(uMsg)
{
case WM_CHAR:
char szChar[20];
sprintf(szChar,"char is %d",wParam);
MessageBox(hwnd,szChar,"swh",0);
break;
case WM_LBUTTONDOWN:

ReleaseDC(hwnd,hdc);
break;
case WM_PAINT:

hDC=BeginPaint(hwnd,&ps);

EndPaint(hwnd,&ps);
break;
case WM_CLOSE:

DestroyWindow(hwnd);
break;
case WM_DESTROY:

break;
default:
return DefWindowProc(hwnd,uMsg,wParam,lParam);
}
return 0;
}

编译的时候没有任何错误，可是为什么就是不能运行呢？
本人初学者，请指教！

太感谢了
我这就回去试验一下~~~
对了，请问我安装的c++6.0是那种解压缩的，有没有那种硬盘安装版的
还有在那里能够下载2001版的msdn
谢谢了

没有试验呢，大概看了一下，有个小问题

int WINAPI WinMain

RegisterClass(&win2007);
HWND hwnd;
“ hwnd=CreateWindow("sunweihang","孙伟航",WS_OVERLAPPEDWINDOW, //要与你上面的类名相同” 难道我的类名不是“win2007”吗

再次感谢，我全部都试验过了，你的解答完全正确！~~
非常感谢

还有个小问题
