event procedures

I seem to be having issues with event procedures and focusing on form fields.

It seems that if within an event procedure I call another global function which focuses on a form field and moves the carret to the end, as the code eventually goes back to the event procedure call,  if I do anything else within the event procedure the text highlighted in the form field is random and peculiar?

If the event procedure after calling the global function does nothing else the correct point in the focused field is  where the carret is placed.

Is this normal?

Is it something to do with being an event handler call rather than a standard function/sub call.

It only seems to behave like this if done within an event handler as described?

Thanks

In what event are you calling this "global function" and what is the function?

I worked it out thanks.

I was trying to pause the event procedure

CODE

   Private Sub docNotes_DblClick(Cancel As Integer)

    Call inputZoom("Documents Request Notes")

    Do Until Not IsLoaded("inputPopUp")
        DoEvents
    Loop

    If bPopZoomChanged Then
    
        Call setDocs(Me.Docs_Form.Form, Me.Adviser)
        
        If Nz(Me.docNotes, "") <> "" Then
            Me.docNotes.SetFocus
            Me.docNotes.SelStart = Len(Me.docNotes)
        End If
    
    End If
    
End Sub

Then continue when form closed, bad practice!

So changed it to make the selection on form close instead like so

CODE

Private Sub Form_Close()

    If bPopZoomChanged And oControl.Name = "docNotes" Then
        [Forms]![Check_Docs].Last_Check = Format(Now(), "yyyy/mm/dd")
        [Forms]![Check_Docs].Checked_By = oUser.Name
    End If
    
    oControl.SetFocus
    If Not IsNull(oControl) Then
        oControl.SelStart = Len(Me.inputTextBox)
    End If
    
End Sub
Works fine now.

I guess you must let event procedures complete as quick as possible, not try to pause them as I was doing.
