I have a ATL COM project which 'exposes' a function RemoveMsgService()<br />
<br />
To start with, I would do a MAPI Logon, and would like to use a separate function to do this, but I don't want the Logon() to be seen by the VB programmers.How do I implement this?<br />
<br />
Also, is it ok for me to require an LPTSTR if the function takes astring as an argument, or should I be using VARIANTS?<br />
<br />
Thank you
