Hi
I tried installing the 11g drivers in order to see if the 10g drivers were the reason of the overflow.... no success
Also I had to install VS 2005 in the x64 machine and I can confirm that is the call to the ExecuteNonQuery method the ones that trigger the exception.
Also I've created a simple WinForms application that follows the same code in order to try to reproduce the error, but in WinForms such line doesn't have any problems.....
Please provide me any advice in order to avoid such exception, I repeat: I'm using the latest versions of CoreLab and Oracle drivers.
Best Regards
Ernesto
