I'm currently learing C++ and MFC by creating a
Device Independant Bitmap (DIB) object which reads
a .BMP file and displays the bitmap via a CDC
object.

The problem:  SetDIBitsToDevice needs a DC for
it's first argument.  SetDIBitsToDevice is not
a member of the CDC class.  The DC attribute
within the CDC class is probably a private item
(can't find it in the Class Libraries Reference
manual).  I cannot find any CDC member which gives
me a DC.  So, how can I get a DC from the CDC 
passed to my DIB paint routine to give to the
SetDIBitsToDevice call?

Thanks in advance for all responses!
John Bunk

P.S.  If someone has already written a DIB object
which can read .BMP files, please let me know!

    Any statements / opinions made here are mine, alone, not the Navy's.
              But that's OK, the Navy is usually wrong anyhow.
