大家帮我看个程序，好困惑的问题！

gg0001

该程序工程内仅有一个qx1.cpp文件，程序功能也仅仅是创建一个全黑色的屏幕。试着编译，编译通过，但按ctrl+F5运行时弹出一对画框（对话框内容如下：
Microsoft Visual c++ Debug Library
        Debug Error!
        Program:\游戏编程\qx1_\Debug\qx_1.exe
       Moudle:
            File:i386\chkesp.c
       Line:42
       The value of ESP was not properly saved across a function call. This is usually a result of calling a      function declared with one calling convention with a function pointer declared with a different calling
convention.
       (press Retry to debug the application)
                   终止          重试          忽略    ） ，            
程序无法运行。我用的是directx 8.1 sdk,include等都已经加在了vc++6.0上，并位于第一位置，dxguid.lib,ddraw.lib也已设置，我已经弄了半个月，dx8.1sdk与dx8.1也重装了许多遍，也不知道问题出在哪里，大家帮帮我啊！
下边是源代码：

qx1.cpp文件
#include <windows.h> // include important windows stuff
#include <ddraw.h>

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

DispatchMessage(&msg);
}
return msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd,UINT message, WPARAM wParam,
LPARAM lParam)
{

switch(message)
{

case VK_ESCAPE:
  ;
default:
return DefWindowProc(hwnd,message,wParam,lParam);
}return 0;}

一个偶然操作：最下边窗口显示：

应该与directx无关

gg0001

那是什么问题啊？，再帮帮我吧，多谢了！！！1

Quest

DirectDrawCreate(NULL, &lpDDraw_temp, NULL)生成的以是DirectDraw对象
lpDDraw_temp->QueryInterface(IID_IDirectDraw,(LPVOID *)&lpDDraw7)))
                                                       |
应该加个7-----------------------------------------|

Quest

QueryInterface完了,,原来那个应该要RELEASE

Quest

LRESULT CALLBACK WndProc(HWND hwnd,UINT message, WPARAM wParam,
LPARAM lParam)
{

switch(message)
{

case VK_ESCAPE:     ///////////////是乎没有这个消息,,这个是按键的虚码
  ;
default:
return DefWindowProc(hwnd,message,wParam,lParam);
}return 0;}

这个消息处理函数好象不太规范

Quest

wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
全白的窗口背景

Quest

wndclass.style = 0;

不知道设0可不可以

Quest

程序结束后要释放资源

写程序要有良好的习惯

Quest

另外,,
while(GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}

这个拿来当主循环不太对吧
