If Web Service Exist?

[joel_dizon]

Hi,

Im writing a small application that checks whether a Web Service in is
available or not using VB.Net. Just need to decide whether to call a
secondary source or whatever. Can anyone help me with this or even
point me in the right direction.

Thanks in advance.

Joel

try calling the WebService from inside a Try Catch End Try block
eg
Try
Dim SomeObject = new WebServiceName()
Catch ex as SoapException
Console.WriteLine(ex.Message) 'Just in Case
'webservice not up
End Try

Does this answer your question?

Hi Karim,

so sorry coz im still new with Web Service in VB.Net but here's what I
did so far...

1. I added a Web References -> MyWebService
2. Reference -> http://localhost/ACMEWS.asmx
3. In Form Class...

Public Class Form1
Inherits Windows.Forms.Form
Private service As MyWebService.ACMEWS

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles Button1.Click

service = New MyWebService.ACMEWS()

End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

End Sub

End Class

if button1 is clicked and web service is down it should notify me that
its down so i can decide which action to take.

are you saying to wrap this...

service = New MyWebService.ACMEWS()

with Try...Catch...End Try ?
