Any way to marshal handle to the device context to a
remote PC.
And is there any equivalent to CClientDC object of
MFC in ATL.

- Design a COM interface which will support all GDI drawing functionality.
- Design a way of passing GDI bitmaps (HBITMAP) over the network by means
of DCOM. You will surely need custom by-value marshalling for this -
“marshal” must extract the bits from GDI internals to the app’s buffer,
“unmarshal” must build the GDI bitmap and set the bits to it. - Do the same for pens, brushes, fonts and regions.
Read the COM documentation on how the monikers are marshalled - they use
by-value marshalling too.
IIRC there were some MS’s interfaces and proxy/stub pairs to do all of
this - possibly part of MSIE, possibly undocumented.
Using DCOM to provide the remote display functionality is really exciting
