Modbus TCP/IP in Visual Basic

I am programming an application in Visual Basic to read and write to a modular through Modbus TCP/IP. I have been successful getting it to communicate through a serial cable in VB, but I am having problems when it comes to communicating with it though TCP/IP in VB. Does anyone know of a good ActiveX controller that will allow me to do this or anything else that might help?

The link that you gave me (it is actually for the program Modbus ActiveX available at, worked great. It took me a little bit to figure out how to use it but it worked. It was also $850 USD cheaper than anything else I looked at. Thinks ^_^
