How to Trigger an event in a Visual Studio Outlook Add-in

Question

I am currently working on a Visual Studio VSTO C# Outlook Add-in project to open a specific type of file from an email when the file is double-clicked, and have it pop up in a new window. How do I handle the double-click function?

Answer 1

It is not clear what files you're speaking of. In case of attachments, you can use the BeforeAttachmentRead , BeforeAttachmentSave , and BeforeAttachmentPreview events provided by all Outlook item types. The Outlook object model doesn't provide any special event when you double click on the attached files.
