I don't know why you get this error.
I would try to put the Initialize out of the JobDone routine, and perhpas change the the event name.
Not sure if this will solve the problem.
Two comments:
- In this line you should use dio values not pure pixel values.
panel(i).AddView(labelinstructionsec(i),scrolltraining2.Width/2-135dip,75,270,30)
- I don't see where you add the labelinstructionsec(i).Tag property.
