Dear Experts,
I am working on a TCP/IP project but my problem is that whenever my programme trying to reconnect again to server then server giving message port number is different.
i.e. every time my programme is run its port no showing different in server so kindly guide how can i fix a particular port number for my programme.
Regards,
pardeep
It seems that the original port was never closed. When it is still open, the following connection will open a new port.
Close the original when exiting the server.
what exactly are you doing..
@Pardeep3dec, please mark this thread as solved if you have managed to get a solution, found at the bottom of this page, thanks.:)
It has been open for some time now.
Exactly my programme is running on client and sending request connection continously when connection established by receiving operation session then we are receiving so many messages but after 30 seconds connection going lost. Programme should connect automatically to that server but programme is unable to connect.
pardeep
@Pardeep, show me the code you are currently using to connect to the server.

Please add code in code brackets for us, it makes it much easier to read, thanks.:)
What I could gather from your code is that it seems that when you open the port again, it is already in use by another control or application. You need to catch the error and then tell the winsock control to connect through another port.
You can try something like -
Public Function CheckPort(msc As MSComm, ByVal p As Integer) As Boolean
On Error Resume Next
msc.commport = p
msc.PortOpen = True
If Err = 0 Then
CheckPort = True
msc.PortOpen = False
End If
End FunctionYou can also try and assign a much higher port number -
Winsock1.RemotePort = 32750
