孙鑫VC 第一课 WINDOWS消息 无法结束进程
就是窗口关闭后进程还在，还蛮占内存。。。
看到的路过的有空的说说呵，谢了哈。

#include <windows.h>
#include <iostream>

LRESULT CALLBACK Winsunproc(
HWND hwnd, // handle to window
UINT uMsg, // message identifier
WPARAM wParam, // first message parameter
LPARAM lParam // second message parameter
);

int WINAPI WinMain(
HINSTANCE hInstance, // handle to current instance
HINSTANCE hPrevInstance, // handle to previous instance
LPSTR lpCmdLine, // command line
int nCmdShow // show state

WNDCLASS wndclass;
wndclass.style = CS_HREDRAW|CS_VREDRAW;

// TerminateProcess(handle,0);
//
break;
default:
return DefWindowProc(hwnd,uMsg,wParam,lParam);

}
return 0;

[解决办法]
Winsunproc函数中没有写捕获关闭的函数
方法1：
case WM_DESTROY:
postquitmessage(0);
break;

方法2：
case WM_SYSCOMMAND
if (wparam == IDCLOSE) {
postquitmessage (0);
}

------解决方案--------------------

C/C++ code

GetMessage(&msg,[color=#FF0000]hwnd[/color],0,0)
[解决办法]
WM_DESTROY消息响应中用postquitmessage(0);
[解决办法]
while (GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
