Service Query. Begin Execute(AsyncCallback, Object) Method
Asynchronously sends a request to execute the data service query.
public: IAsyncResult ^ BeginExecute(AsyncCallback ^ callback, System::Object ^ state);
public IAsyncResult BeginExecute (AsyncCallback callback, object state);
member this.BeginExecute : AsyncCallback * obj -> IAsyncResult
Public Function BeginExecute (callback As AsyncCallback, state As Object) As IAsyncResult
Delegate to invoke when results are available for client consumption.
User-defined state object passed to the callback.
The BeginExecute method uses the same semantics as the Execute method, however BeginExecute asynchronously sends the request so that the call does not block processing while waiting for the results from the service. According to the standard begin-end asynchronous pattern, the provided callback is invoked when query results are retrieved.
