specified cast is not valid

[Random]

I haven't the slightest idea what is causing this problem. I get an error
in calling the Invoke method in my Web Reference to my Web Service. The
error is...
-----------
An unhandled exception of type 'System.Web.Services.Protocols.SoapException'
occurred in system.web.services.dll

Additional information: System.Web.Services.Protocols.SoapException: Server
was unable to process request. ---> System.InvalidCastException: Specified
cast is not valid.
-----------

My web method has two string arguments and returns an integer....

Hi,

ehhh.. What is returned by

Dim results() As Object = Me.Invoke("Authenticate", New Object() ,
{UserID, Password})

And are you sure the first entry of the returned array is castable to
an integer? => CType(results(0),Integer)

Hope this helps,
