Initiates the asynchronous execution of a SQL statement that is described by this ULCommand, and retrieves the result set, given a callback procedure and state information.
Visual Basic Public Function BeginExecuteReader( _ ByVal callback As AsyncCallback, _ ByVal stateObject As Object _ ) As IAsyncResult
C# public IAsyncResult BeginExecuteReader( AsyncCallback callback, object stateObject );
callback An System.AsyncCallback delegate that is invoked when the command's execution has completed. Pass null (Nothing in Microsoft Visual Basic) to indicate that no callback is required.
stateObject A user-defined state object that is passed to the callback procedure. Retrieve this object from within the callback procedure using the System.IAsyncResult.AsyncState property.
An System.IAsyncResult that can be used to poll, wait for results, or both is returned; this value is also needed when invoking EndExecuteReader(IAsyncResult), which returns an ULDataReader instance that can be used to retrieve the returned rows.
