Switchable graphics notification

Hi

I am developing an application for a system having following switchable graphic cards:
AMD M880G with ATI Radeon HD4225 + ATI Radeon HD 5430
and Windows 7 OS

Is there any notification that I could get when the card is being switched.

I can see that the switching is not allowed when IE 8 is running.
A message "Switching the graphics processor cannot occur until your current applications are closed" pops up. So I believe there is some notification.

Could someone tell me how to prevent switching between graphics cards while the application is running.

Thank you

hi

im not an expert on hardware, but why would you want to switch graphic cards while your computer is switched on? and what do you mean by switching are you going to use 2 graphic cards?

I don't think the OP means physically switching :)
