.Net Client app holding socket...

It would be very useful to provide the code where you actually call the web service.
Not sure if this helps but it's worth a try.
Public Function SetUpWS() As EmpInfoWS.EmployeeInformation Dim wsEmpInfo As New EmpInfoWS.EmployeeInformation wsEmpInfo.Url = GetEmpInfoWSURL() wsEmpInfo.Credentials = System.Net.CredentialCache.DefaultCredentials Return wsEmpInfo End FunctionJason W. -
I have a .net windows client application that queries a .net web service. After the client has called the web service if netstat is run from the command line the results will show 10 sockets still open. Below is the code from my client app. My questions are 1. Why does the client app need 10 sockets? 2. What can I do to force the closing of the sockets since the GC.Collect() & GC.WaitForPendingFinalizers() methods don't seem to be doing it? 3. Does it really matter if the sockets are not immediately closed?
Private Sub LogIn() If IsUserOffLine() Then Exit Sub Dim wsEmpInfo As EmpInfoWS.EmployeeInformation = BF.SetUpWS() Try wsEmpInfo.SetEmployeeCheckIn(BF.GetUserName, txtLogInComments.Text) Catch Ex As Exception Call IsUserOffLine() Finally wsEmpInfo.Dispose() End Try Dim tRefreshForm As New Thread(New ThreadStart(AddressOf RefreshForm)) Try tRefreshForm.Start() Catch ex As Exception tRefreshForm = Nothing End Try End Sub Private Sub RefreshForm() Try Call PopulateForm() Call HandleNotify() Call ShowScrollingNote() Call CleanUp() Catch End Try End Sub Private Sub CleanUp() Try GC.Collect() GC.WaitForPendingFinalizers() Catch End Try End SubI appreciate any suggesting you have, thank you. Jason W.was is the actual state of the connection? its probably in a PENDING_CLOSE state (or something like that). xacc-ide 0.0.15 now with C#, MSIL, C, XML, ASP.NET, Nemerle, MyXaml and HLSL coloring - Screenshots

Cool, is there a site that tells about the socket status options. I need to point my manager to it so he will get off my back. Thank you for the help. Jason W.

If he doesnt believe, tell him to hire a consultant to come tell him the same, and a formal written apology to you and his superior. He will shut up quick. But I'll have a look while I'm at it. :) xacc-ide 0.0.15 now with C#, MSIL, C, XML, ASP.NET, Nemerle, MyXaml and HLSL coloring - Screenshots

http://www.skynet.ie/~heathclf/fyp/fyp-interim/node13.html[^] The TIME_WAIT state is a state that all the TCP connections enter into when the connection has been closed. The length of time for this state is 240 seconds, which is to allow for any duplicate segments still in the network from the previous connection to expire. If you have direct access to the TcpClient or Socket class in your webservice (not sure of that), you can try tweaking some of the settings.

AFAI can see, its part of the TCP/IP stack, not sure how u would go around changing it. Also any routers between you and the destination could have some control over it too. xacc-ide 0.0.15 now with C#, MSIL, C, XML, ASP.NET, Nemerle, MyXaml and HLSL coloring - Screenshots

If it isn't a problem I would like to pick your brain a little more. I found an article that says 'The side shutting down the connection gets the TIME_WAIT.' is this true. If it is then I don't need to worry about causing a denial of service on the server. Thoughts? Jason W.
