Override 'Cancel' in event procedures - forms

Question

There is data validation in my MS Word user form which returns the focus to the textbox where the user entered something incorrect. Now I am trying to accommodate the user's change of mind: instead of correcting the entry, I want him to be able to exit the form (click the Exit command button), in which case the entry would be discarded. I suppose that a solution would start with not using the text box's exit event. I little help from someone who knows the answer would save me a lot of testing time, perhaps to find out that I can't do it.
Does anyone know?

Answer 1

I understand that you are handling the Exit event of the Textbox, setting the Cancel output parameter if the data is not valid.
There's a tricky but simple solution that permits to keep that working and still have an Exit button. It permits to activate the handler of the Exit button without requiring the focus to leave the Textbox. This way you can unload the Form safely in this handler.
Try this it works pretty smoothly:
1- Set the property TakeFocusOnClick of the Exit command button to False. You can do that at design time in the property-sheet, or at run-time i.e. at UserForm_Activate
2- just unload the form when the Exit button is clicked:
Private Sub ExitButton_Click()
Unload Me
End Sub

Answer 2

#A.S.H provided the key to the solution below. His point is that it is possible to call another event procedure while Cancel is active in the Exit procedure of a control. That other procedure can be used to rectify the condition in the first control which is triggering the Cancel, thereby enabling an orderly exit. The all-enabling condition is that the control on whose click event the rectifying procedure is to run must not take the focus when clicked (meaning it can run without triggering an exit from the control stuck on Cancel). I have added code to the exit procedure to set CmdExit.TakeFocusOnClick = False when a Cancel condition arises there. Now, ...
Private Sub CmdExit_Click()
' 12 May 2017
' if CmdExit can't take the focus it can't be the ActiveControl
If Not ActiveControl Is CmdExit Then
Select Case ActiveControl.Name
Case "Cbx107"
Cbx107.Value = ""
Case "Tbx53"
Tbx53.Value = "0"
End Select
With CmdExit
If Not .TakeFocusOnClick Then
.TakeFocusOnClick = True
.SetFocus
End If
End With
End If
' now CmdExit is the ActiveControl
MsgMe "Cmd Exit: ActiveControl = " & ActiveControl.Name
Me.Hide
End Sub
