Device Context with 2 monitors.

Hi,

2 monitors are connected to the computer. I need to get the Device Context from one and from the other. How it can be done ?

We have only one hDC (device context) for both the monitors together.

Total area occupied by both the monitors on this hDC is

WITH OBJECT FW_VirtualScreen()
   ? :nTop, :nLeft, :nBottom, :nRight, :nWidth, :nHeight
END

To find the Recangle of any monitor in the Virtual Screen space:

WITH OBJECT  (oMonitor:= FW_GetMonitor( nthMonitor )
   ? :nTop, :nLeft, :nBottom, :nRight, :nWidth, :nHeight
END

Thank you, Mr.Rao !

Sorry I didn't understand - the FW_VirtualScreen() function returns an object of type TRect. How can I get DC from it ?
