VB.Net basic coding help needed

I am new to Web Services and a novice with vb.net. I am trying to set up a basic web services program to get a list of customers.  I have the following simple code copied from another post:

Dim CustomerList As New com.netsuite.webservices.CustomerSearch
        Dim CustomerSearchBasic As New com.netsuite.webservices.CustomerSearchBasic
        Dim Customersrchenum As New com.netsuite.webservices.SearchEnumMultiSelectField
        Dim Customerval(1) As String
        Customerval(0) = New String("_customer")
        Customersrchenum.operatorSpecified = True
        Customersrchenum.operator = com.netsuite.webservices.SearchEnumMultiSelectFieldOperator.anyOf
        Customersrchenum.searchValue = Customerval
        CustomerSearchBasic.stage = Customersrchenum
        CustomerList.basic = CustomerSearchBasic
        Dim Customers = srv.search(CustomerList)

My problem is with the last line. I am running Visual Studio 2005 and I keep getting the compile error that says that srv is undeclared. I can't figure out how to declare it. All of the samples I see on the forum don't have it declared. I know I am missing something very simple. Any help would be greatly appreciated. Thanks, Jim.....
