There is one dialog box and only one edit control in my dialog-based MFC application. At design time, I set the edit control to be as big as half of the dialog box. At runtime, whenever I change the dialog's size, I want to the edit control always to scale up to half of the new size of the dialog box. How can I do that ?

Thanks.

Hi,
Add the WM_SIZE message handler to your application and add the following code to change the size of EditBox in OnSize(..):

 CWnd *pWnd = GetDlgItem(IDC_EDIT1);
  CRect cr, dr;

  pWnd->GetWindowRect ( cr );
  GetClientRect(dr);
  ScreenToClient ( cr );
  pWnd->MoveWindow ( cr.left, cr.right, (dr.right-dr.left)/2, (dr.bottom-dr.top)/2, TRUE );

Good Luck!
