[vtkusers] displaying the objects in the windows crated by MFC

[kshivann]

hi,
  i am trying to display objects in windows created by MFC. the function 
SetParentID takes in handle to window  (HWND) in win32 programming. We have 
equivalent device context CDC in MFC. when i pass the variable of type CDC i 
am getting an error that no object displayed.

what is the appropriate variable that i should pass in

thanks
