Hi,

I'm using Visual Studio 2008 SP1 with DevArt Developer Tools version 2.55.9 on a german Windows XP SP3 (VS is german too). Every time I launch Tools->Oracle->License Information, I get the descibed error-window. What's wrong?

Please, make sure that you have the recent build of OraDeveloper Tools installed (there was no public build under version 2.55.9). Once we already solved similar issue, it was compatibility problem with dotConnect for Oracle.

Hi Duke,

sorry. My Version of the tools is 2.55.148. I'm using dotConnect for Oracle Version 5.35.54.0.

Tanks, Alex

Please follow these steps:
1) reinstall dotConnect for Oracle v 5.35.54;
2) specify the type of project for which this problem persists;
3) post here the call stack when the error occurs.

To obtain the call stack, connect from the 1-st Visual Studio (Debug | Attach to Proccess) to the process of the 2-nd Visual Studio in which you invoke the Tools->Oracle->License Information dialog. Before attaching don't forget to make these settings in the 1-st Visual Studio (you are using to debug the 2-nd one): a) in the (Debug | Exceptions) window select Common Language Runtime Exceptions; b) in the (Tools | Options) window, Debugging | General - clear Enable Just My Code (Managed Only).
