connecting to SAP

[Former Member]

I'm new to the SAP .Net arena. I'm trying to connect to SAP but, I'm getting the following error and I'm not sure how to resolve it. Please advise

{System.NullReferenceException}

[System.NullReferenceException]: {System.NullReferenceException}

HelpLink: Nothing

InnerException: Nothing

Message: "Object reference not set to an instance of an object."

Something you pass seems to be uninitialized, but you don't give enough information to guess what you do (e.g. source code of your call). Anyway I recommend that you use SAP .NET Connector version 2.0.

It appears that I need to set up the parameters that will allow my proxy to access SAP. EX. connection string, destination, password and so on. Can you recommend a site that will show me the syntax to set up these parameters?

Hi,

Hope you don't mind, but I moved your question from the SDN Suggestions Forum to this one on .NET Technologies as I think this will be more likely to get you an answer.

Best Regards,
