To get the Form from its Processhandle

Question

Is there any way to get the Form from its Processhandle ? Some thing like this.

Form form = (Form)Form.FromHandle(_process.MainWindowHandle);

But this is not working.

It might help if you elaborated on how the line is not working, is it throwing an exception, returning null? — Steve Ellinger, Sep 24 '10 at 16:08
What are you trying to accomplish? Is the target form of your own design, or is it from a third-party application? — Reinderien, Sep 24 '10 at 16:08

According to this post, that only works for window handles owned by your process. You can't use Form.FromHandle to get a form from some other process.

It's possible to do this from within a process. Trying to grab a Form or Control from another process won't work.

Can you give us some more information as to what you're trying to do here with the Form? There may be a better way to accomplish it.
