Question : Creating a child window

I want to create a simple child. For this purpose I created a new class derived from CWnd. I wrote a new Create method:
RECT WindowRect;
WindowRect.left=0;
WindowRect.top=0;
WindowRect.right=400;
WindowRect.bottom=400;
if(CWnd::Create(NULL,"AviWindow",WS_OVERLAPPED|WS_BORDER|WS_CAPTION|WS_VISIBLE|WS_CHILD,WindowRect,AfxGetMainWnd(),NULL,NULL))
      {            
      return(1);
      }

But I do not get a visible new child window when I call this method. I can call the program but nothing happens despite the fact that I get a warning:
Warning: calling DestroyWindow in CWnd::~CWnd; OnDestroy or PostNcDestroy in derived class will not be called.
What is wrong ?

Answer : Creating a child window

You're not creating the window correctly.  The code below will create a window but it's not a very useful one.  What are you trying to do in the window?


      RECT WindowRect;
      WindowRect.left=0;
      WindowRect.top=0;
      WindowRect.right=400;
      WindowRect.bottom=400;

      CWnd *myWnd = new CWnd();
      if(!myWnd->Create(NULL, "AviWindow", WS_OVERLAPPED|WS_BORDER|WS_CAPTION|WS_VISIBLE | WS_CHILD,WindowRect,AfxGetMainWnd(),NULL,NULL)){
            AfxMessageBox("Error in Create", MB_OK);
            delete myWnd;
      }
      
      myWnd->ShowWindow(SW_SHOWNORMAL);
