Using Threading

[Daniel Romaniuk via .NET 247]

Hello,

Can you help me with this problem?
I've developed a Class (class A) that receives socket events, itis handled in a Thread that raise events to other class (ClassB) that has instanced this class. The class Class B cannot showa form in the event because the form locked. Why it occours? I'mshowing not modal form, it's look like I'm blocking the threadthat raise events..

Hi, Daniel

You might need to check on which threads your events are executed. Easiest
way is to use Debug.Print or Console.WriteLine in event handlers, which
print thread id or names (if have them unique for every thread running). It
might happen you try to show form on non-UI thread. That's one thing.
Another is - how you show form, Form.Show or Form.ShowDialog?
ShowDialog might work Ok, Show will require message pump, which exists only
on UI thread.
