Hi,

>I don't quite understand, can you expand a little.

As I understand it (and this is just from reading - haven't experimented) the GDI API has two functions that allow you to obtain details of existing clipping region for a device context: GetClipRgn() and GetRandomRgn().
The first, which only handles regions created explicitly by the user (i.e. using SelectClipRgn), has a .NET equivalent.
The second, which details regions created by the systems BeginPaint() doesn't seem to have a .NET equivalent.

Don't currently have a practical need for the latter - I was just curious...
Regards,
Viv
