4.4 Getting the Value of a Property
This example shows a sequence of messages between an automation client and a server to get the value of a property.
The client calls the Invoke method on the server by using the DISPID returned from the server. Other parameters can be filled as shown in the following diagram. The property value is returned by the server in pVarResult. If an exception occurs during execution, or if there is an error in the arguments passed to Invoke, it is indicated in pExcepInfo or in pArgErr, accordingly (see section 18.104.22.168).
