On mouse click need to send text string via ip to open port

:confused:

Am new to vbasic, bought .net. Have created a simple UI that I will expand on with checklistboxes with a list collection. When I check one I want only one checked at a time and when one is checked, need to send a specific text string found in a table or text file somewhere that I will maintain to an open ip port on remote machine i.e. 10.137.0.100 7070. This will in turn be received by a tcl program and it will respond appropriately by controlling other devices locally connected. I will not need a response from the other machine nor or will I do anything with one.

Have looked at sockets and other possible methods, I suspect there is a relatively simple answer for my more than likely simple nees.

Any help is GREATLY appreciated.
