IBM Lotus C++ API 7.0a for IBM Lotus Notes/Domino Directory Release --------- ------------------

//===========================================================================
//
//      Module: IEXPORT.CPP
//
//      Description:
//              This program illustrates how to import a CGM graph image
//              file to document in a database file.  It then exports all the
//              text from that document of the same database to a text file.
//
//      Syntax: IEXPORT <dbname> [server]
//
//		Note:
//				This sample program is designed to work with the sample 
//				database SAMPLEDB.NSF and the sample "graph.cgm" file.
//
