Entire Connection API

I’m trying to use the Entire Connection API, but the documentation I have for it isn’t particularly helpful. Here are some basic questions I have:

Is it usable from Visual Basic? If so, which version(s)?
Are there any code samples available?
Is there any further documentation online?

Thank you.

The API of Entire Connection 4.4.1 is supporting Visual Basic 6 and Visual C++.
The API of Entire Connection 4.5.1 is supporting Visual Basic .NET 2005, Visual C# .NET 2005 and Visual C++ starting from Version 6.
There are code samples availabel on the CD. The directory is Windows\API.
