Using the Winsck.ocx (named oSock) on a client communications form, we are getting the above error when trying to set the LocalHost or LocalPort from within the Connect() method of the oSock, or when we attempt to assign a value using the Bind() method. We are trying this because it won't get a good connection so we are attempting different things. This worked when it was PRG-based, but now we are converting it into a VCX and can't seem to get a connection. Any ideas welcome.
