Hey, thank you for your help.

But I have another problem.

I have an embeded engine Window in a form.
Now I want to feed my Form with data from the engine thread.
Is this possible? I don't now that much about threading in csharp.

Another question: How do I pass a parameter value to a Scheduled method?

Edit: Ok, the last problem is solved. I should read your examples more carfully . Is the AddEventObject method the only possible way to pass a parameter? So I guess I have to create a data structure with the information I want to pass?
