.Net DLL integration on Navision v4.0

krigan

Hi all!
We are currently working with a 3rd party, trying to integrate a .Net DLL file with C/AL, and we are experiencing issues while trying to use it from Navision.
We are the developers of the DLL. The DLL contains methods and functions to connect (TCPIP) to an EFT system for credit card validation.
We tried some FAQs we found on the web, to compile our .Net DLL in order for NAV to use, to no avail.
We have successfully registered the DLL, we are using .Net framework 2.0.
But when we try to initialize our library, we get the attached NAV error.
Any ideas on what the error means?
I can provide a copy of the DLL if that helps.

Regards.

Try to use Visual Studio debugger to check what is the problem (just set NAV as application to debug when you have the source code of your dll opened, set breakpoints, try run the code in NAV and it shold catch what you need).
