Maybe this will help you even though it is not exactly what you describe.  This will "mark" all of the text when the control gets focus thus enabling the user to replace the entire contents without having to delete or mark the contents himself.
Create a form and place 2 text boxes and 1 masked edit box on the form.  Paste the following code:

Private Sub MaskEdBox1_Gotfocus()
Call SelectMe(Me.ActiveControl)
End Sub

Private Sub Text1_GotFocus()
  Call SelectTxt(Me.ActiveControl)
End Sub

Private Sub Text2_GotFocus()
  Call SelectTxt(Me.ActiveControl)
End Sub

Private Sub SelectMe(This As MaskEdBox)
  This.SelStart = 0
  This.SelLength = Len(This.Text)
End Sub

Private Sub SelectTxt(This As TextBox)
  This.SelStart = 0
  This.SelLength = Len(This.Text)
End Sub


You will note the behaviour when you run the pgm.  I have found this approach especially useful on masked edit controls.
