i have five forms in my c# project. one host an httplistener that i want to run continionsly. when the listener gets a message, it passes it to a static class, which in turn calls the appropriate forms for another processing.
is it possible that the static class calls the new form in a new thread? if so please help me out
The code in the forms should only deal with the visual aspects of the form. Anything else,especially http listeners, should be handled with separate classes running on background threads.
"Calling a form" doesn't mean anything, I guess you'd only want to Show() it. Creating a form on a worker thread is never a good idea. Even if you do get the thread state right (STA and message loop), you'll have hard-to-solve Z-order and modality problems.
Simply use Control.Invoke to run code on the UI thread. It should create the form and call its Show() method.
