I’m having a problem upgrading a c# app from WinXP to Win7 64 bit.

I’m having a problem upgrading a c# app from WinXP to Win7 64 bit. The app queries data from our iSeries. I’ve set up a 64 bit ODBC DSN, which works if I try from within MS Access. But, when I try to establish a connection in the C# code, I’m getting the following error:

ERROR [08S01] [IBM][iSeries Access ODBC Driver]Communication link failure. comm rc=10022 – CWBCO1003 – Sockets error, function returned 10022

My connection code is as follows:

cn = new OdbcConnection("dsn=as400data;UID=user;PWD=password;");
cmd = new OdbcCommand(sql, cn);
cn.Open();

Anyone have any ideas as to what may be raising this error?

    I’ll put this here in case someone else has this problem one day.

    The resolution to this problem was to put the code under development directly on the C:\ drive of the development machine. Typically, I keep my code out on a network drive, so that it gets backed up. There’s some kind of issue with doing that in Win7, however.
