Some Problem with Winsock.....

Hi all !
        I have been developing with Winsock for quite a while. Now I am facing a very strange problem. When ever I add Winsock control to any project of mine the project runs OK but I can't stop the program without VB being crashed. For example I added a winsock control named Winsock1 (with default settings) to my form and added the following code. With no code what so ever on the form (No other controls or anything) I cant close my program while clicking on the "Cross button" or even adding an "End" statement in a button to close and each time VB crashes.

Private Sub Form_Load()
        Winsock1.LocalPort = 7070
        Winsock1.Listen

End Sub

I know there might be something wrong with my Winsock but how to correct it?

are you closing the socket like :

Private Sub Form_Unload(Cancel As Integer)
 Winsock1.Close
End Sub

I've had a similar problem before and fixed it using an application built to fix winsock issues.
But it was a while ago and can't find the setup application anymore.

Is your XP SP2 Firewall turned on?  If so, try turning it off and see if that problem goes away.

One more thing: What protocol are you using - TCP or UDP?

Hai,
   This is purely your operating system problem.  because your firewall is going to restrict the connection.  so pls. turnoff the windows firewall system and then try this.  it will work fine.

If your XP Firewall is OFF and still you're having the same problem, then check to see if you have other firewall installed, such as BlackIce, Zone Alarm, Norton, etc.
