Good day,

Sorry to bother you so often, but as soon as i overcame the driver loading issue, i have run into connection problem.

When pess fill in all data and press connect on Oracle 10g/11g Drivler (ODP.NET 10.2.x) screen, i get the following exception:

Object reference not set to an instance of an object.

Stack trace:

My tnsnames.ora file is in correct location (10.2.0\client_1\NETWORK\ADMIN) and correctly configured:

VENDOR = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.9)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = VENDOR) ) )

any idea on how to work arround it?

Once again - configuration: Windows Vista 64bit LLBLGenPro 2.6 final DEMO (October 9th, 2009) + x86 louncher see thread: (http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=17043) ODP.NET 2.102.2.20 Oracle client 10g latest

We will look into it. We'll provide you a debug build of the driver to see on what line the driver crashes. Sorry for these inconveniences...

We saw there's a 64bit ODP.NET as well (see your other thread). The 10gR2 32bit ODP.NET installer refused to run on windows 7 64bit (dunno why, it required windows 6.0 or lower, windows 7 is v6.1), I'll now try the 64bit bit odp.net and see if that works at all on windows 7 64bit with llblgen pro.

I'll attach the debug driver and pdb file in a second so you can run these (on 32bit) and see what linenumber the exception occurs.

Edit Attached. Please copy the driver + pdb file in the Oracle10g folder and run the designer on 32bit, to reveal the line number where the error occurs exactly. (complete with stacktrace please).

However, as I said in the other thread, it's likely better to use 64bit ODP.NET on 64bit windows, considering it's a stack of wrappers around other code.
