I have the code below that will evaluate a string of characters. If
its less then 12 long it will trigger a message box if its  equal it
will save the information and close the form.

I have this currectly on a button event, how could i place this same
logic say once i enter in my last character it will trigger the
logic written in the button control.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnOK.Click
       If Len(Me.txtBarCode.Text) = 12 Then
           _barcode = Me.txtBarCode.Text
           Close()
       Else
           MessageBox.Show("The Current BarCode Scanned was not
correct, Please Re Enter")
           Me.txtBarCode.Text = String.Empty
           txtBarCode.Focus()
       End If
   End Sub

Move the code from Button1_Click into a new sub. Call the sub in the Click
handler and additionally in the Textbox' TextChanged event. (But, as a user,
I would like to be able to edit the text I entered until I pressed the
button.)

- Show quoted text -

Armin, if i move the code or create another sub and place it under the
text change event. Each time i enter a number i get the message box
because the text change event is evaluating it each time.
