Showing a form in an .Net Outlook Add-In

Are you entirely sure that your add-in is loading? Has it been disabled
maybe. Have a look in Outlook, Help, About, Disabled Items.

Try putting a MsgBox in the Connect class to make sure that you are
connecting correctly.

There was an exception in the form's constructor that being thrown but not
caught by Outlook, so the code hung. I've corrected the code and the form
works as expected.

Incidentally, is there a type of exception that I can be caught by Outlook?
Probably a COM-type exception, I'll wager.

Thanks for your time, Ken.

Alan-

There was an unhandled exception in the form's constructor that resulted in
the odd behavior.

Thanks for your reply.

When you use a try...catch block in your managed code you'll be catching
both .NET errors as well as COM exceptions.

Depending on what your code is doing you might also cause unhandleable
exceptions that won't come to your error handling and in some cases might
only fire after your addin is disconnected or Outlook is closed. I've seen
that with some errors that were seen with WordMail where after exit you see
a kernel32 error.

Outlook itself isn't going to catch any errors for you, but it will fire
errors up through the CLR and those would be COM exceptions since Outlook is
unmanaged code.
