Q:

Code to open my application Login form when I try to open any Web Browser installed on my system

I am trying to open my app's Login Form whenever I try to double click and open any web browsers installed on my system. I have spent around a week without any success. Any help, articles, code or links would be of great help.
Thanks.
I am using Visual Studio 2010
Programming Language : C#

A:

Trying to intercept every browser launch probably requires monitoring the system processes. I.e., your app will constantly be running and whenever a recognized browser process starts, you spawn your login form. There may be system events to hook into (I am not sure), but How can I list all processes running in Windows? might be a good starting point to get an idea what's possible.
A somewhat different approach would be to register your app as the system's default browser. That way, you will be notified, can spawn your LogIn form and can than delegate to an actual browser.
I am not sure what ultimate goal you pursue, and whether either is a good solution depends heavily on whether there are more constraints to it than you mention explicitly.
