Syntax

'Declaration
Public Delegate Sub DataAsyncCommandEndEventHandler ( _
    result As Object _
)

public delegate void DataAsyncCommandEndEventHandler(
    Object result
)

public delegate void DataAsyncCommandEndEventHandler(
    Object^ result
)

type DataAsyncCommandEndEventHandler = 
    delegate of 
        result:Object -> unit

JScript does not support delegates.

Parameters

• result
  Type: System.Object
  The value returned by the command.

Remarks

This delegate is called when an asynchronous method call made to a DataAsyncCommand object has completed execution.

The result is always equal to the return value for the equivalent synchronous method, as follows:

• The AsyncPrepare method returns a String object

• The AsyncDeriveParameters method returns a DataParameter object.

• The AsyncDeriveSchema method returns a DataReader object.

• The AsyncExecutemethod returns a DataReader object.

• The AsyncExecuteWithoutResults method returns a Int32 object.
