Hi,
This is one great article. Actually the best I have seen yet. I just have one issue if I may raise it here. I am not sure whether it should be on a spearate thread but if this is not the correct place please move it to wherever you see fit.
Well, I have an issue with invoking my main from to update its UI from an external class rather than the same class like you explained. What I am doing is as follows:
1. Declare a public delegate on the form
2. Declare a public procedure on the form
3. Spawn an instance of my external class and do some work and then update public variables in an external module.
4. When done, I get a handle on the main form using
Application.OpenForms("mainForm")5. Invoke the UpdateUI procedure in the form like this:
Application.OpenForms("mainForm").Invoke(New UpdateGUIDelegate(AddressOf mainForm.UpdateUI))The code proceeds with no errors and by stepping through code I can see the textBoxes get assigned the value in the public variables. however, the form text boxes never show the new values!! I tried using application.doevents but no luck. I also tried adding a check on me.invokeRequired at the begining of the UpdateUI form but it always returned FALSE.

Please help..
Thanks
