Checking for new tasks running

Hey,

I was wondering is there a way using C# to check wether a new window pops up ?

Basically what i want to achieve is something like controlling an LCD ( which i already know how to do). Its just so that when im playing games or whatsoever that is in fullscreen mode ill get a flash on the lcd when a new window pops up....

Any kind of eventlistener or something for this ?

Thanks in advance,

Ganglylamb,

:edit:
nevermind i already figured out how to get information on some of the running processes , with a bit of messing around ill be able to make my own event handler for this thing.

for those that care

Code:

---

using System.Diagnostics;
Process[] pro;
pro = Process.GetProcessesByName("msnmsgr");

---

was what i needed, since i want to be able to display the name of the person who contacts me trough msn on the LCD when in a fullscreen application.
