Displaying documents/files?

I need to be able to display 1 or 2 files that are attachments in emails.

The email bit is ok, but I don't really want to display the files in their own applications, I would rather show them within some controls on my form.

As far as I can see the OLE control is best used for this, but I can't seem to do a few things.

• I can't select the type of file at run time.
• I can't seem to scroll the files.
• I want to set it so that the user can't edit the file through my app.

Anybody able to help me with any of these, or suggest another way for me to go about this?
