updating parent form from child object

[shwaguy]

Using C#.net express edition I created an application that has the main code in the parent form. In this form I create an object and I want that object to change values in the parent form before the object returns a value (I am doing a progressbar). I could create a form object from the child object but that would not look as nice. HELP! shwa guy

Either have your object fire progress events, which you can wire and use to update your ProgressBar from the main form, or pass the ProgressBar to the object and have it do the update directly. The first method is more code, but vastly preferrable. If your object uses threads, beware of UI marshalling issues. Share and enjoy. Sean

thanks for the reply. I still do not know how do what I need to do, but I think I might be on the right path now. I never had to fire events before, I guess I am about to learn. shwa guy
