Access VBA put a form element name as an argument

Let's see if anyone knows how to solve this problem:

I have a form with several elements: Some of them are textboxes called A1, A2, A3, A4...

Now, their AfterUpdate SubProcedure is extremely long but barely similar for each of them: A1_AfterUpdate, A2_AfterUpdate, A3_AfterUpdate...etc... are very similar but for the names of the textboxes they change.

My idea was to gather all that was equal in a subprocedure defined this way:

Private Sub Update(Box As String, Menu As Boolean)

   If Menu=True{ 

   Me!Box.Text = "This is the text that is going to change"

   }

End Sub

So, the only thing I must do is to call it this way, for instance:

Update(A1, True)

But it doesn't seems to work. Any idea on how to reach this objective?

Box as TextBox not as string. You should concider public generic function or Class with eventhanders

Add a class module - I've called it clsTextBoxEvents.

Add this code to the class:

Public WithEvents txt As Access.TextBox



Private Sub txt_AfterUpdate()

    MsgBox txt.Name & " has been updated."

End Sub

In your form module add this code:

Public MyTextBoxes As New Collection



Private Sub Form_Open(Cancel As Integer)



    Dim ctl As Control

    Dim txtBoxEvent As clsTextBoxEvents



    For Each ctl In Me.Controls

        If TypeName(ctl) = "TextBox" Then

            Set txtBoxEvent = New clsTextBoxEvents

            Set txtBoxEvent.txt = ctl

            txtBoxEvent.txt.AfterUpdate = "[Event Procedure]"

            MyTextBoxes.Add txtBoxEvent

        End If

    Next ctl



End Sub

The MyTextBoxes declaration must be at the very top of the module.

This just adds the AfterUpdate event to all textboxes on the form. You'll probably want to refine that a bit to textboxes with specific text in the name, or controls that are in a specific frame on the form.

Impressive, but seems complex. Did you ever actually use such construct ? A use case perhaps ? Thx

I don't understand the role of the MyTextBoxes collection. By reading the code with my knowledge it seems that nothing is done with it. What do I miss ?
– Patrick Honorez
Nov 22 at 13:23

The MyTextBoxes collection should be Private really as it's only used in the form. The collection is used to store each instance of the class - one for each textbox. Without the MyTextBoxes.Add txtBoxEvent at the end none of the events fire.

@PatrickHonorez I have to say I've not used such a construct in Access as I'd usually use a Continuous Form set up if I had lots of controls doing the same thing, but that would need changes to the tables as well. I've used similar code in Excel when creating controls at runtime. Now you've got me trying to think of a useful use case and all I'm thinking is "are very similar but for the names of the textboxes they change" from the OPs question.
– Darren Bartrup-Cook
Nov 22 at 14:01

@PatrickHonorez I use this type of construct all the time for validating or restricting input - i.e. a group of TextBoxes that only accept numeric input. If you think this is "complex", you haven't seen the code-behind with 5 or 10 duplicate copies of a KeyPress event. This is much cleaner.
