How do I interpret the error output?

[=?Utf-8?B?SnVzdGluIERvaA==?=]

I am still a novice with .NET and I am little bit struggling with debugging.
I am trying to find the cause of the error.
Is it the problem with system.data.dll or libdata.dll or what?

Any feedback from your experience is greatly appreacited.

Thanks.
Justin

It looks like you're trying to access a database with a connection string,
and something is wrong with the connection string or it has not been
supplied. The problem is on your end.

Don't you have some beginner books?
