在消息框中是/否功能

Question

我想在InfoPath 2007中向消息框添加一個是/否函數（是否確定要退出？）。如果用戶單擊「是」，則InfoPath表單將關閉，如果不，那麼用戶會被帶回表單。從我讀過的內容來看，這不會發生在InfoPath中。所以，我添加了一個具有「是/否」按鈕的新窗口窗體。

對於'否'按鈕，我有（me.close）它關閉了窗體窗體，用戶留下了InfoPath窗體。當用戶點擊「是」意味着他們想關閉窗體窗體和InfoPath窗體時，我需要幫助。以下是我的代碼到目前爲止。提前謝謝了。

Imports Microsoft.Office.InfoPath 
Imports System 
Imports System.Xml 
Imports System.Xml.XPath 
Imports System.Diagnostics 

Public Class Confirm_Close 
Private Sub btnNo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNo.Click 

Me.Close() 

End Sub 

Private Sub btnYes_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnYes.Click 

Try 

<need help here> 

Catch ex As Exception 

Console.WriteLine(ex.Message) 

End Try 

End Sub 

End Class

     Me.Close() 

    End If 

End Sub
