show MessageBox while opening word document.

Question

I want to display the MessageBox when i open the new document or edit existing document from my SharePoint library.

What i have done is as below,

1. Registered the event handler for the DocumentChange event.

this.Application.DocumentChange += new Word.ApplicationEvents4_DocumentChangeEventHandler(Application_DocumentChange);

2. I am getting the MessageBox when i open the word document/edit existing document from sharepoint document library,

    but the issue is if there are more than 1 word documents open & if i change the focus from one document to another, the DocumentChange event gets called & each time the MessageBox gets called & displayed

3. I want the MessageBox to appear when i open new document or edit existing document, but not when i change my focus from one open document to another.

is there any other event or properties which i can use to validate the achieve the above criteria?

Hi Kunal

Use the DocumentOpen event, instead of DocumentChange. That will only fire when a document is opened.
