Generates an OnDataRequest event on the specified provider component.
Use AS DataRequest to invoke an OnDataRequest event handler of the provider named by ProviderName. AS DataRequest is provided to allow application developers to customize the communication between a client application and a provider component. There is no predefined meaning for the DataStream parameter or the return value (Delphi) or AS DataRequest _result parameter (C++).
Note: Applications can only call the AS DataRequest method using the IAppServer interface.
