Add timeout to a webservice response

I have a function in my VB.NET application which consumes a webservice. That webservice is a bit inconsistent and does load. That is, if i go to it's wsdl URL when it is down, it would not load for 2 minutes and then return "Not available".

So in my function I want to give the web service 30 seconds to respond. If it does not then i would like to go to the next step. Can I do that?

Sub Bind()
GetWebService()
getOtherData()
End Sub

Sub getWebservice()
Dim webservResponse As String
Dim oXmlResponse As New System.Xml.XmlDocument

'Add timeout for the entire getWebservice function (or) just the line below.

  webservResponse = webservice.getinvoicexyz(<username>, <password>, billnumber)

End Sub

Did you "attach" to this web service by going to "Add Service Reference"?

Angel02Author Commented:
yes. I did that. I actually went to "Advanced" and added as a web reference.
"getinvoicexyz" is a method in the webservice.

OK, was there a bunch of stuff added to your app.config/web.config?

You need to use a thread or a backgroundworker and kill it after a set time limit if it does not come back.

Not really. Only username and password for the webservice.

@CodeCruiser
I tried something like this right before calling the webserive but not sure how this works

             Dim aTimer As Timer

            ' Create a timer
            aTimer = New System.Timers.Timer(5000)
           
            AddHandler aTimer.Elapsed, AddressOf callbk
            aTimer.Enabled = True

Looks like there is an easier way. There is a timeout property on the client itself which you can use

This is what I did in my method. I don't have a way to check this as the webservice hasn't timed out since I made this change. So hopefully this is right.

Sub getWebservice()
      Dim webservResponse As String
      Dim oXmlResponse As New System.Xml.XmlDocument
      Dim webservice As New MyLiveWebService.mywebservMethod

      webservice.Timeout = 5000
        webservResponse = webservice.getinvoicexyz(<username>, <password>, billnumber)

End Sub

Did you test it against a dummy webservice which takes longer than 5 seconds to return result?

Angel02Author Commented:
How can I find a dummy webservice? I know it has to be valid so what is the best way?

CodeCruiserCommented:
You can create a dummy webservice yourself.
