Hi John,
thanks for your answer. To write a custom Event is one thing, but what fires the Event actually? Let's say I've got 15 TextBoxes on each TabPage. You surely don't mean, that I should implement my Event on every TextBox TextChanged-Event?

Hello SA, hello Alan,
thanks for your answers. Hmm, it's pretty complicated. After reviewing all your links, documentations etc. the picture is still not much as clear as I hoped. I wish I could have from you (if it were possible) a following manual:
1. design decision: a form, a button, some methods on it should run in "classical" top-down manner, but NOT as a single thread (form freezes...) and wating for each other to be complited.
2. what to use: background worker or ansynchronous method (pros and cons?)
3. simple working example
4. that would be (from my point of view) a perfect manual. For a beginner it's hard enough. :-)
Regards

Hi Alan,
thanks for your answer. I've already tried to solve my problem using BackgroundWorker, but it will not work with the completion event.
Unfortunately your solution doesn't work either. I suppose I place the next action (in my case the method no. 3 under the button after copying) in "finally" block. There is also a method 4 as well and the program tries to start with the method 4 immidiately and crashes, for copying must be finished befor the method 4 can start...
Regards

Hi, thanks for your answer and working example. That explains a lot (I'm still reading your code, some things are new to me..). Anyway: I still don't know how to put other methods together and make them work top-down? My goal: every single step should wait for complition of the previous one (copying, installing, executing some scripts, copying, install other routine etc.). At every single step I want to show the progress bar stating the app-progress. How to make the single-methods wait "for each other"? As I said: it's essential that one method waits for another one to be finished for there is no point trying to ínstall before some files needed for the installation are not copied yet etc. How to put the single steps together ( a Queue or something)? Thanks for any hints.

Thanks for your answer. Hm, there is another problem with background worker.
1. The worker doesn't "wait" and comes immidiately back to method that calls him. Acutally it's essential to me, that all the methods are running top-down (first: coopying, then installing, otherwise it makes no sense..) I know, I could put the next method calls in the worker method "on complition", but it means I'd have to change o lot in my code. Is there any other method to run progress bar without using the background worker?
Thanks

ups, sorry for posting the answers..
thank you for the answer. Ok, I can see what you mean. I'm fully aware that my solution with the different threads is a bit cumbersome, but I still don't know the proper approach to solve my problem? Simply put: I need an idea how a professional programmer (not a new-be just like me) would do it?
Andy
