Answer 1

Secure string is a "Special" type of string in the .net framework. It's encrypted.

Here is how to convert a string to a secure string: http://social.msdn.microsoft.com/Forums/en-SG/netfxbcl/thread/ada5def5-0d80-43d6-ab5d-9fb1934e6556

This being said, I don't think this will achieve what you want it to. The username and password option on process start is for starting the application (IE in your case) and running it under a different account.

Your approach is not going to work. GMail is not a regular Windows program, the kind that you can start with Process.Start(). It is coded in Javascript and runs in your browser. The login procedure is handled by Javascript.

You'll need a browser plug-in to tinker with GMail. A popular one that works on Firefox is Greasemonkey. Lots of GMail hacks in this google query .
