关于带有计时器的列表框和标签 [英] About List Box and Labels with Timer

问题描述

亲爱的所有人，我正在使用visual basic 2008制作一个发送短信的程序。我对ListBox和带标签的标签有一些困难。请帮我解决我的问题。

我的问题是：



1 - 我有一个带有手机号码的ListBox作为Listbox的项目。

2-我有3个标签。

   （第一个标签用于显示列表框项目）

   （第二个标签用于显示计数1到10）

   （第三个标签用于显示结果，如发送，确定）



我的问题是当用户点击发送消息按钮时。然后label1 show第一项，标签2开始计数1到10，完成后计数第三个标签显示结果如发送即可。



此第一个标签后再显示列表框项目没有2并计算开始等等。当完成列表框中的所有项目时，一条消息显示操作已完成。



请帮助我在这件事上。



我使用下面的代码，但这段代码只显示计数和结果。
