Hi David,

Did you try: thisXDocument.View.Window.Close(true); just for the sake of it?

Thanks Franck. My apologies for not being clear, when I try to close the form I am using:

thisApplication.ActiveWindow.Close(true);

It works fine when InfoPath has focus, but fails when another window has focus.

BTW, it's definitely the thisApplication.ActiveWindow.Close() code that is causing the exception.

I've wrapped the code in a try...catch section and can at least trap the error.

Closing Form using ActiveWindow.Close()

I'm wondering if anyone else has encountered an issue with closing forms using C# and thisApplication.ActiveWindow.Close() in particular:

My form submits data to a K2 web service and, upon successful submission, displays a dialog box and then exits InfoPath using thisApplication.ActiveWindow.Close().

Unfortunately, if a user decides to change the focus to a different window during the form submission, the dialog box is displayed fine but the InfoPath form doesn't close and instead a "Object reference not set to an instance of an object" exception is raised.

Any thoughts as to what is causing the problem? Is it an issue with the web service I'm calling or the window that I'm trying to close?

I've tried to regain the focus by using thisApplication.ActiveWindow.Activate() prior to calling Close() but to no avail.

Thanks in advance,
David.
