Windows Service obtaining display device context using GetDC(NULL)
I am writing a windows service running on Windows Server 2003. The service performs some printing operations by obtaining a printer DC and a display DC. I'm wondering if there should be any issue for the service (running as SYSTEM user) to call GetDC(NULL) or if there is any reason to be concerend about this call? Will it return NULL or have any problems associated with the display HDC returned?
