Hi.
I have an issue which drives me crazy, I know it may not be related to the Add-in Express library, but if you have any suggestion, it would be appreciated.
The context is: Outlook addin based on your library.
On some client's machine I've got AccessViolationException calling the Outlook Explorer object get_AttachmentSelection function.
Detailed technical information follows:

I checked the TypeLib and the Interface registrations of the interop library (PIA), and it seems valid.
We are using the Office interop extensively in the addin, and the fact it only came up for this call reminded me that this function wasn't implemented in the Office 2007 PIA.
What do you think, is it possible that somehow the Outlook loaded the wrong dll? How can I check that?
Is it possible if the Outlook loading the correct interop library, the library not using the correct COM object but an old one?
Thank you. |

Hello Sven,
Try to call AttachmentSelection after a delay created as we describe in section Wait a Little, see the PDF file in the folder {Add-in Express}\Docs on your development PC. I would also try to get AttachmentSelection after AttachmentSelectionChange occurs (if it occurs after you select a new Outlook item).

Hi Andrei,
thank you for your quick answer.
Unfortunately I cannot reproduce this issue, and every test takes a long time to manage.
Could this explain why it not comes for every client, but a several ones? Shouldn't it occur on every client?
You give me a good idea how to test if it is a timing issue, if I put a test button on the ui and on the button's click event I try to use the interop call. If it is working, it must be a timing issue. |

Hello Sven,
I don't know. This may be different Outlook builds used or different sets of COM add-ins. Depending on the implementation of the AttachmentSelection object, this may be caused by something non-trivial such as IE settings.
