mailto with attachment using Outlook

[bsmh]

I'm creating an Adobe Air app. The code I'm using is:
'mailto:[email protected]?subject=testing123& body=This is a test and only a test'

This will open Outlook and create the email with the right email address, subject, and body. Then I add this code to add an attachment.
&attachment="mytextFile.txt"

The problem is, with that code added, Outlook gives me an error that says "The command line argument is not valid. Verify the switch you are using". Has anyone else seen this error before? How do you fix it? Any help is much appreciated.

Maybe its complaining because you're giving it a relative path. As far as outlook is concerned, it has no idea where mytextFile.txt is... maybe try giving it a full absolute path?
