address in use?

says address in use? Don't really understand.

frmFileTransfers.Winsock1(frmFileTransfers.Winsock1.Count - 1).Connect IPAddress, 9106

EDIT: attached the project.
error acurses in frmFileAcceptDialoge in the Accept button.

forgot project

Try another port

changing the port doesn't work.

Wild guess:

This Winsock control is being reused a second time, and ultimately a third time, etc. Its LocalPort property is not being reset to zero (0) before re-using it, i.e. Connect being called again.

A Winsock "address" consists of the protocol (TCP vs. UDP), local port number, and local IP address taken together in this context. Using a LocalPort of 0 tells Winsock to allocate a free ephemeral port and assign it for you. It's a bit like using FreeFile() to allocate a file number for VB native I/O operations.

so change localport to 0 then set it to whatever i want to set it to?

Set LocalPort to 0 before doing each Connect.
