For example, Visual Basic. NET can also use compiled managed code to access the same object, as shown in the following example:Imports SystemImports System. Runtime. InteropServicesModule WKOClientSub Main ()Dim WSDLMoniker ="Soap: wsdl = http: // localhost/CSSoap. Calc. soap? WSDL"Dim obj as ObjectObj = Marshal.
The services|web|xml| check box compiles and runs this Visual Basic. NET application, producing the same output as the previous two VBScript samples.
Because the server application publishes components as CAO and Wko two forms, the remote client chooses the activation method. Although it may only make sense for academic research, a single client computer can indeed use two remote activation methods of the same component to access the virtual root of

For simplicity, the examples above all use VBScript to access the WEB service. The SOAP WSDL moniker can actually be written using Visual c+, Visual Basic 6.0, Visual Basic. NET, or C #. For example, Visual Basic. NET can also use compiled managed code to access the same object, as shown in the following example:
