NotifyIcon help

Question

I have a C# application that uses the NotifyIcon control and stays in the notification area when not in use.  I have another application that is able to run a program when a phone call comes in and pass command line arguments to it that contain the call details.

The end result is that  I want it to cause my application to maximize and display the results of a query that was run using the call details.  Can someone point me in the right direction as to what function I should be looking at?  I don't want to launch multiple instances of the application, I just want to pass arguments into it while it is already running.  Basically maximize and display the new query results on each incoming phone call.  I am new to C#.  My development experience is mainly in PHP, so I find myself in a slightly different world - but a very appealing new world.

Thanks in advance for any push in the right direction.  :)
