Assumes pVectorWindow points to a valid LVectorWindow object.
This example centers the LVectorWindow object in the parent window.

L_INT LVectorWindow__GetVectorWndExample(LVectorWindow *pVectorWindow) 
{ 
   L_INT    nRet; 
   RECT     parentRect, vectorRect, moveRect; 
   L_INT    moveWidth, moveHeight; 
   HWND     hWndParent = ::GetParent(pVectorWindow->GetVectorWnd()); 
 
   if (hWndParent != NULL) 
   { 
      ::GetClientRect(hWndParent, &parentRect); 
 
      nRet = pVectorWindow->GetVectorRect(&vectorRect); 
      if(nRet != SUCCESS) 
         return nRet; 
 
      moveWidth = vectorRect.right - vectorRect.left; 
      moveHeight = vectorRect.bottom - vectorRect.top; 
 
      moveRect.left = ((parentRect.right - parentRect.left) - moveWidth)/2; 
      moveRect.top  = ((parentRect.bottom - parentRect.top) - moveHeight)/2; 
      moveRect.right = moveRect.left + moveWidth; 
      moveRect.bottom = moveRect.top + moveHeight; 
 
      nRet = pVectorWindow->Move(moveRect, TRUE); 
      if(nRet != SUCCESS)
