Create new form from alternate thread

[xmutantduck]

Hi, I am trying to write a program that can spawn forms when running in
an alternate thread outside the main one. It however doesnt like to do
anything related to the first thread when in the second one. How can i
create a secondary form from an alternate thread? Thanks.

I am courious why you would want to create the forms on separate threads.
Instead of running forms in separate threads I suggest to put the operations
the forms are performing into separate threads and keep all of the forms
running in the application's main thread.

If you want the alternate thread initiating the display of other forms
then you need to use Control.Invoke to marshal a method onto the main
UI thread where you can safely display other forms.

Thanks. I will look more deeply into what you said brian.

The reason I am trying to initiate forms from an alternate thread is
because I have a thread running as a listner, and when it detects an
incomming packet, it displays a chat window. I have attempted putting
it all in its own class(s) and using events, but it was being... cool.
So basically, there WAS no way for me to have the main thread initiate
the form.

I also needed the forms to be able to send and receive messages while
open, so OpenDialog wouldnt cut it.
