afxDump (CDumpContext in MFC)
Provides basic object-dumping capability in your application.
afxDump is a predefined CDumpContext object that allows you to send CDumpContext information to the debugger output window or to a debug terminal. Typically, you supply afxDump as a parameter to CObject::Dump.
Under Windows NT and all versions of Windows, afxDump output is sent to the Output-Debug window of Visual C++ when you debug your application.
This variable is defined only in the Debug version of MFC. For more information on afxDump, see Debugging MFC Applications.
