Winsock Ping Timeout

[JoshA56]

I have a client/server app and on the server.exe it shows a list of all the connected clients. My problem is that if a client incorrectly closes the program (example: turns off their computer) the IP will remain there. Is there something I can do to check if the client is connected to the server? I also wish to have this check be regular for all clients connected to the server.

In your program, do you have any code in the QueryUnload event?

If not, you can code that to detect a shutdown. Example:

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
'there are 5 unloadmode levels
        Select Case UnloadMode
            Case vbFormControlMenu 'UnloadMode 0
                 'form is being unloaded via the Close
                 'or by hitting the X in the upper right hand corner
                 'command from the System menu
            Case vbFormCode        'UnloadMode 1
                 'Unload Me has been issued from code
            Case vbAppWindows      'UnloadMode 2
                 'Windows itself is closing
            Case vbAppTaskManager  'UnloadMode 3
                 'the Task Manager is closing the app
            Case vbFormMDIForm     'UnloadMod 4
                 'an MDI child form is closing because
                 'its parent form is closing
        End Select
End Sub

I would play around with vbAppWindows......if someone just shuts their PC off with your program running, then that event might pick it up.
