Unit 14: Text and Graphics Output

underlying device context is released to Windows upon return from the call to your OnDraw Notes
function.
CClientDC objects encapsulate working with a device context that represents only the client
area of a window. The CClientDC constructor calls the GetDC function, and the destructor calls
the ReleaseDC function. CWindowDC objects encapsulate a device context that represents the
whole window, including its frame.

Did u know? CMetaFileDC objects encapsulate drawing into a Windows metafile.

!
Caution In contrast to the CPaintDC passed to OnDraw, you must in this case call
OnPrepareDC yourself.

Task Illustrate the function of CClientDC objects.
