Msgbox是否和取消按钮在VB.NET 2010中工作

Question

下面是我的MsgBox代码." 是"按钮正在工作,但是当我单击" 否"或" 取消"时,它仍然会删除数据...

        strup = "DELETE FROM student WHERE urno =" & CInt(txtUrn.Text) & ";"
        Dim command As New OleDb.OleDbCommand(strup, con)
        MsgBox("Do you want to delete record(s)", MsgBoxStyle.YesNoCancel, "Confirm Delete")
        command.ExecuteNonQuery()
        con.Close()

单击" 否"或" 取消"时如何取消删除操作？

Answer 1

使用基本If声明.该MsgBox不会取消任何东西.

If MsgBox("Prompt", MsgBoxStyle.YesNoCancel, "Title") = MsgBoxResult.Yes Then
    ' execute command
End If

您还可以使用MsgBoxStyle.YesNo仅获得"是"和"否"按钮.
