BeginExecuteNonQuery(AsyncCallback, Object) method

Initiates the asynchronous execution of a SQL statement that is described by this ULCommand, given a callback procedure and state information.

Syntax 
Visual Basic

Public Function BeginExecuteNonQuery( _
   ByVal callback As AsyncCallback, _
   ByVal stateObject As Object _
) As IAsyncResult
C#

public IAsyncResult BeginExecuteNonQuery(
   AsyncCallback callback,
   object stateObject
);
Parameters

  • 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.

Return value

An System.IAsyncResult that can be used to poll, wait for results, or both is returned; this value is also needed when invoking EndExecuteNonQuery(IAsyncResult), which returns the number of affected rows.
