Threading question

[Guest]

Is it safe to create a form in a worker thread and then have the UI thread
display and take control of it? I would think that this would not be safe.
However, .net 2.0 does not give me a cross threading error and it works
consistently with all of my forms except for one.

No.

I'm surprised that it's not giving you an error, but no, it's not safe.
Always create GUI elements on the same thread you'll be touching them
on.

Cross-threading probes are only active in debug mode.
