Help on ADO with ObjectARX

[Anonymous]

I am just trying to get connection to external database using ado
#import directive. Infact I just merged the code from two samples and they works fine separately but when I pull them together its showing following errors:

c:\temp\aaa\debug\msado15.tlh(2667) : error C2059: syntax error : 'constant'
c:\temp\aaa\debug\msado15.tlh(2667) : error C2238: unexpected token(s) preceding ';'

code:
// aaa.cpp : Initialization functions
#include "StdAfx.h"
#include "StdArx.h"
#include "resource.h"
#include
#import "C:\Program Files\Common Files\System\ado\MSADO15.dll" rename("EOF", "ADOEOFile")

StartOLEProcess( ) {

Please help me.

Thanx to google after many ours of searching with various combinations of keywords I found that it was due to naming conflict and modifying my #import directive to :

#import "c:\\program files\\common files\\system\\ado\\msado15.dll"
\
rename ("EOF", "adoEOF") \
rename("EOS","AdoEOS")

solved my problem.
