Help! A Stranger Problem with FormView resizing

Hi, all:

I have a problem of resizing controls  in a FormView for both width and height with a MDI application.

For example, if Y direction resizing works fine  then X-direction resizing won't work. Or , if X direction resizing works fine  then Y-direction resizing won't work.  But if the form’s height is decreased to a small value, the controls in the form will be X-direction resizable then it is Y-direction in-resizable. That is, the controls’ width will change with the change of the form width. BUT in this case, controls’ height can not be changed any more until the form width is changed to a small enough value!

What I did is as below:

void  CMyFormView:OnInitialUpdate( void )
{
   CRect       rctMaxForm( 0, 0, 0, 0 );  // Form max rectangle to initialize the form

   // Get Parent frame rectangle to determine max the form size
   this->GetParentFrame()->GetClientRect( rctMaxForm );

   // Store the form original size with an attribute before it is changed
   this->GetWindowRect(  m_rctOriForm ); // m_rctOriForm is a data member of the class
   ScreenToClient( m_rctOriForm );

   // Initialize the form position with the max size for resizing controls later
   this->SetWindowPos(  NULL  // pWndInsertAfter
                      , 0     // left
                      , 0     // top
                      , rctMaxForm.Width()
                      , rctMaxForm.Height()
                      , SWP_NOMOVE | SWP_SHOWWINDOW
                      );
}

void CMyFormView::OnSize( UINT nType, int cx, int cy )
{
   CFormView::OnSize( nType, cx, cy );

     // Get a pointer to the control
     CEdit*  pCtrl = ( CEdit* )GetDlgItem( IDC_EDIT );
   
    if( cx > m_rctOriForm.Width() )
    {
      CRect rctEdit;
      pCtrl->GetWindowRect( rctEdit );
      rctEdit.right += (cx - m_rctOriFoem );
      // Update th edit control dimensions
     pCtrl->MoveWindow(rctEdit );
   }

    if( cy > m_rctOriForm.Height() )
    {
      CRect rctEdit;
      pCtrl->GetWindowRect( rctEdit );
      rctEdit.bottom += (cy - m_rctOriFoem );
      // Update th edit control dimensions
     pCtrl->MoveWindow( rctEdit );
   }

}

When I tested these functions, I found that either X or Y direction resizing works fine. However, I can not get the CEdit object resized with both X and Y direction at the same time.

I am wandering why it happens and how to solve the problem. I guess that the problem may come from the m_OriForm's value.

Could anybody give me an idea?

Thanks in advance!

how about

void CMyFormView::OnSize( UINT nType, int cx, int cy )
{
   CFormView::OnSize( nType, cx, cy );

     // Get a pointer to the control
     CEdit*  pCtrl = ( CEdit* )GetDlgItem( IDC_EDIT );
   
    CRect rctEdit;
    pCtrl->GetWindowRect( rctEdit );
    bool bChanged=false;
    if( cx > m_rctOriForm.Width() )
    {
      rctEdit.right += (cx - m_rctOriFoem );
      bChanged=true;
   }

    if( cy > m_rctOriForm.Height() )
    {
      rctEdit.bottom += (cy - m_rctOriFoem );
      bChanged=true;
   }

   if (bchanged==true)
     pCtrl->MoveWindow(rctEdit );

}

also are the following right

      rctEdit.right += (cx - m_rctOriFoem );
     
should it be

      rctEdit.right += (cx - m_rctOriFoem.Width() );
     
also

should

      rctEdit.bottom += (cy - m_rctOriFoem );
     
be

      rctEdit.bottom += (cy - m_rctOriFoem.Height() );

Hi!
// IMHO there is error:
CRect rctEdit;
>>pCtrl->GetWindowRect( rctEdit );
rctEdit.right += (cx - m_rctOriFoem );      // Update th edit control dimensions
>>pCtrl->MoveWindow(rctEdit );
call ScreenToClient to convert coordinates:
CRect rctEdit;
pCtrl->GetWindowRect( rctEdit );
ScreenToClient(rctEdit);
rctEdt.right = cx - 2*rctEdt.left; // left border around control
// Update th edit control dimensions
pCtrl->MoveWindow(rctEdit );
