Hi Boris!

Thank you! The following code works now to geht PresShell but how can
i now render in my own DC?
RenderDocument requires gfxContext, but where can I get this one?
There is a gfxSurfaceType   "SurfaceTypeWin32Printing" -> i think i
will need this one :-)


 
nsIInterfaceRequestor* pInterfaceRequestor = NULL;
					mMozView->GetInterfaceRequestor(&pInterfaceRequestor);

					nsPIDOMWindow* psPIDOMWindow = NULL;
					nsID xIDDOMWindow = NS_PIDOMWINDOW_IID;
					if(pInterfaceRequestor)
						pInterfaceRequestor->GetInterface(xIDDOMWindow,
(void**)&psPIDOMWindow);

					if(psPIDOMWindow)
					{
						nsIDocShell* pShell  = psPIDOMWindow->GetDocShell();
						if(pShell)
						{
							nsIPresShell* pPresShell = NULL;
							pShell->GetPresShell(&pPresShell);  // WORKS !!!! :-))

							if(pPresShell)
