Dynamically Consuming Web Services

[mfr]

Hi all,

In a project I'm working on, I need to call web services methods based on
information that is given to my client program only at run-time.
I get the wsdl url, the name of the method to call and the parameters to use.

While that would not be a problem with the old SOAP toolkit, I found no way
to call webservices in VB.NET 2005 at run time.

All the articles, whitepapers, tutorials,... start with "in solution
explorer, add a web reference...". That's not gonna work for me as I only
know which web service I'll call at run-time.

I can't believe that dynamically calling a web-service in VB.NET is harder
than with VB6 and the old SOAP toolkit (3 lines of code), thus I must be
missing something big.

Any suggestion will be more than welcome.

Thanks a lot.

In the Project explorer of your client app:
Lets assume you added a web referebce as Test .
Right mouse click on Test Click on Properties.
In the Properties pane you will notice a propery 'URL Behaviour'
Set that to Dynamic.
Open Reference.vb and modify the function according to your need:
For example:
Public Sub New()
MyBase.New
Dim urlSetting As String =
System.Configuration.ConfigurationSettings.AppSett ings("TestService")
If (Not (urlSetting) Is Nothing) Then
Me.Url = String.Concat(urlSetting, "")
Else
Me.Url = "http://Mydomain/TestService.asmx"
End If
End Sub

Hope this helps.
