infinite change event over flows

If I use the textrtf property for the richtextbox then the change event is executed. But in my change event it uses the textrtf property so then there goes an infinite loop witch then results to an over flow. Create a textbox or richtextbox and for the change event put this.

Text1.Text="hello world"

Now there will be an infinite loop. In this example how Can I stop the infinite loop?

Thanx in advance!

Code:

Private Sub Text1_Change()
    If Text1.Text <> "hello world" Then
        Text1.Text = "hello world"
    End If
End Sub

This would stop an infinite loop in your test example, but not sure if it can be applied to your problem.

Thanx for trying but I would not be able to apply that to my project. Iam editing a richtextbox via RTF code. This is much faster than using the .Sel properties. I have managed to successfully do this. Now I need a way to do this when the change event is executed. But in the change event it changes the RTF of the richtextbox thus the change event is executed in an infinite loop. Anyone know a way to stop the infinite loop?

Thanx in advance!

Try creating a statc variable in your event handler and check it for a given state or value on entry. If it's in the 'active' state, then immediately exit the event handler.

Code:

Public Text1_Change()
Static Flag as Boolean
   If Flag = True then
      Exit Sub
   End If
   Flag = True
   Your Code
   Flag = False
End Sub
