Forms: Move and Resize form windows from code

   Often times, it's necessary to open forms in specified locations and size them to a custom size. Windows API are the most convenient way of doing this, but the converting between the different coordinate systems can be a pain.

    This Class Module hides the API functions and provides generic methods to move and size your forms. The class, once imported in your application, can be used in in a couple of ways.

    1. To align the tops of two forms (at the position of the topmost form):

'********** Code Start ************
Public Sub AlignTops(ByRef frmA As Form, ByRef frmB As Form)
  Dim fwA As New clFormWindow, fwB As New clFormWindow
  fwA.hwnd = frmA.hwnd
  fwB.hwnd = frmB.hwnd
  If fwA.Top < fwB.Top Then
    fwB.Top = fwA.Top
  Else
    fwA.Top = fwB.Top
  End If
  
  Set fwA = Nothing
  Set fwB = Nothing
End Sub
'********** Code End  ************

    2. To move a form to the top right corner of the Access window:

'********** Code Start ************
Public Sub MoveToTopRight(ByVal strFormName As String)
  Dim fwForm As New clFormWindow
  Const SMALL_OFFSET = 5  'Used to position window slightly _
  			  away from the Access MDI window border _
                          in order to avoid appearance of the Access _
                          window vertical scroll bar.
  With fwForm
    .hwnd = Forms(strFormName).hwnd
    .Top = .Parent.Top
    .Left = .Parent.Width - .Width - SMALL_OFFSET
  End With
  Set fwForm = Nothing
End Sub
'********** Code End ************
