为什么搜不到源码例子？

执行这句没反应是什么原因？DialogBox(hInst,"Upgrade",hwnd,(DLGPROC)DlgProc);
函数
BOOL CALLBACK DlgProc(HWND hdlg,UINT message,WPARAM wParam,LPARAM lParam)
{
     switch(message)
     {
     case WM_INITDIALOG:return 1;
     case WM_COMMAND:
         e[h][g]-=LOWORD(wParam);
         EndDialog(hdlg,0);
         return 1;
     }
     return 0;
}
