This example demonstrates how to produce a dialog box when an answer to a question is required.

 'Create a new ALTADataSet object. 
 Dim ADS As New ALTADataSet
 
 'Overrides requested. Create a new class and inherit ALTAEvents. Then set the dataset's events. 
 Private Class myEvents
     Inherits ALTAEvents
     Public Overrides Sub Question(sender As ALTADataSet, sMsg As String, Buttons As MsgBoxStyle, ByRef Answer As MsgBoxResult)
         MyBase.Question(sender, sMsg, Buttons, Answer)
             '<Add additional code here.> 
     End SubEnd Class
 
 'Set the new Events class. 
 ADS.Events = New myEvents
 
 'Initialize the MsgBoxStyle and MsgBoxResult variables. Three buttons will be displayed. 
 Dim Buttons As MsgBoxStyle = MsgBoxStyle.YesNoCancel
 Dim Answer As MsgBoxResult 
 
 'Ask a question. Result will be updated in Answer. 
 ADS.Events.Question(ADS, "Continue?", Buttons, Answer)
