I am creating a VB.NET Winforms application in VS 2005.  I have an MDI Parent form which includes a menu bar and toolbar.  All of the other forms within the application are opened up as MDI Child forms.  After entering data into the child forms, I would like to be able to click on the Save button on the parent form toolbar, but I can't quite figure out how to find out what the last active child form was.  Any suggestions?

this might help in finding the child form....

  Private Function CheckActive(ByVal pChildName As String) As Boolean
        '//////////////////////////////////////////////
        '//  Check to see if the form
        '//  is already open for viewing
        '//////////////////////////////////////////////
        For Each childForm As Form In Me.MdiChildren
            If TypeName(childForm).ToUpper = pChildName.ToUpper Then
                childForm.Activate()
                Return True
            End If
        Next
        Return False
    End Function

Here is what I ended up having to do:

Dim frmChild As Offer
frmChild = CType(Me.ActiveMdiChild, Offer)
frmChild.SaveData()
