Hello Guy.
I finally fixed the problem yesterday after reading the IBM iSeries Access Developper Toolbox documentation. In fact, CCSID 65535 is used to avoid any conversion and that is the reason why I can't get my data properly (it's in binary or hexadecimal format). But there is a very easy solution to bypass the problem and force the system to convert to any other CCSID, using the "Force Translate=<new CCSID>" parameter in the connection string :
<connection>.Open "Provider=IBMDA400;Data Source=SystemA;Force Translate=0", "Userid", "Password")
A value of 0 (zero) will force the conversion to the retrieved job CCSID of the iSeries signon server job during connection authentication.
Thanks,
Christian Bufacchi.
