Re: C++ Issues

Ethan

Get him to install the 8.1.7 Client (Programmer) option on the Win2K Visual Studio machines. I noticed some slight source changes needed going from the 7.3.4 Proc*C version...i.e. EXEC SQL DECLARE's are needed everywhere now....but they should be able to pre-process, compile and link. the question would be whether or not the 8.1.7 NET8 DLL's are backward compatible with the 7.3.4 DLL's that they will be running against...my _guess_ is that they would be ok

Cheers

Jeff Herrick

ps....If they are going to switch don't go to OCI or ODBC...get

      them to use Oracle Objects for OLE
