偶提个VC的新手问题，搞OD调试的高手相信不少都会VC，偶也不浪费时间去找VC论坛了，干脆在看雪直接提问吧。最近想学VC，到网上查到孙鑫老师的视频教程。自己调试下看看,出问题了。源码：
test.cpp:

#include <windows.h>
#include <stdio.h>

LRESULT CALLBACK WinSunProc(
  HWND hwnd,
  UINT uMsg,
  WPARAM wParam,
  LPARAM lParam
);

int WINAPI WinMain(
   HINSTANCE hInstance,
   HINSTANCE hprveinstance,
   LPSTR lpCmdLine,
   int nCmdShow
)
{
   WNDCLASS wndcls;
   wndcls.cbClsExtra=0;
   wndcls.hbrBackground=(HBRUSH)GetStockObject(BLACK_BRUSH);
   wndcls.hCursor=LoadCursor(NULL,IDC_CROSS);
   wndcls.hIcon=LoadIcon(NULL,IDI_ERROR);
   wndcls.hInstance=hInstance;
   wndcls.lpfnWndProc=WinSunProc;
   wndcls.lpszClassName="Weixin2003";
   wndcls.lpszMenuName=NULL;
   wndcls.style=CS_HREDRAW|CS_VREDRAW;
   RegisterClass(&wndcls);
   
   HWND hwnd;
   hwnd=CreateWindow("Weixin2003","北京维新科学技术培训中心",WS_OVERLAPPEDWINDOW,
           0,0,600,400,NULL,NULL,hInstance,NULL);  
   ShowWindow(hwnd,SW_SHOWNORMAL);
   UpdateWindow(hwnd);
  
   MSG msg;
   while(GetMessage(&msg,NULL,0,0))
   {
   TranslateMessage(&msg);
   DispatchMessage(&msg);
   }
   return 0;
}
LRESULT CALLBACK WinSunProc(
  HWND hwnd,
  UINT uMsg,
  WPARAM wParam,
  LPARAM lParam
)
{
   switch(uMsg)
   {
   case WM_PAINT:
           HDC hdc;
       PAINTSTRUCT ps;
       hdc=BeginPaint(hwnd,&ps);
       TextOut(hdc,0,0,"北京维新科学技术培训中心",strlen("北京维新科学技术培训中心"));
       EndPaint(hwnd,&ps);
       break;
   case WM_CHAR:
       char szChar[20];
       sprintf(szChar,"char is %d",wParam);
       MessageBox(hwnd,szChar,"weixin",MB_OK);
       break;
   case WM_LBUTTONDOWN:
       MessageBox(hwnd,"mouse clicked","weixin",MB_OK);
       HDC hDC;
       hDC=GetDC(hwnd);
       TextOut(hDC,0,50,"计算机编程语言培训",strlen("计算机编程语言培训"));
       ReleaseDC(hwnd,hDC);
       break;
   case WM_CLOSE:
       if(IDYES==MessageBox(hwnd,"你是否要退出程序？","weixin",MB_YESNO))
       {
             DestroyWindow(hwnd);
       }
      break;
    case WM_DESTROY:
        PostQuitMessage(0);
        break;
    default:
        return DefWindowProc(hwnd,uMsg,wParam,lParam);
    }
    return 0;
}

   调试时候，编译米问题。但是就是米法创建.exe和.obj文件。错误提示为：
--------------------Configuration: test - Win32 Debug--------------------
Linking...
LINK : fatal error LNK1168: cannot open Debug/test.exe for writing
执行 link.exe 时出错.

test.exe - 1 error(s), 0 warning(s)

偶懂VB，VC现学现卖。肯定代码哪个地方有问题，偶实在米精力在某处错别字上浪费时间，请各位大虾指教。
