Most this information is widely available in any VB.NET book, and even the VB.NET help has at least a working example of doing syncronous connections.

I think if O'Reilly network wants to really help out, someone should post a complete TCP or low level socket application that demonstrates how two applications can communicate ASYNCHRONOUSLY.
