Trackbar Infinite Loop

[ETCorp]

Here is what I want:
- simple trackbar
- numeric box that shows the value of the trackbar
- changes in the trackbar show in the numeric box
- changes in the box are reflected in the trackbar

Implementation:
- I have implemented this as a trackbar with a numeric scroll box below
- I used the ValueChanged event for the trackbar to update the value of the numeric box
- I used the ValueChanged event for the numeric box to update the value of the trackbar

Issue:
This causes an infinite loop where the 2 controls continuosly keep updating each other. I just want this to happen 1 time each way.

I am sure that someone has run into this before. Is there a way to temporarily disable events? Am I using the wrong controls? Is there a different way to approach this?

Works fine for me, what's your code?

Add a updating flag, like this:

Update-Events:
If Not Me._updating Then
      Me._updating = True
      theOtherControl.Text/Value = thisControl.Text/Value
      Me._updating = False
End If

Something like this.

Turns out that this was not the issue. There was an endless loop in another part of my code. The actual issue here was that the compiler was complaining about a NULL object that was being used before being set. I have no idea why this was happening becuase the particular object was set during the parent form load event. I have changed the way that part of this code works anyway, so now its not an issue.

Thanks anyway.
