首先单击“产生10个随机数”按钮来产生10个随机数，并显示在10个文本框中；然后选择一种“演示模式”和“排序方式”，其中演示模式可以直接给出排序结果，也可以通过动画动态演示整个排序过程，排序方式可以按从小到大顺序，也可以按从大到小顺序排序。

（2）在主窗口的空白区单击鼠标右键，弹出快捷菜单。

从中选择“排序算法”命令，打开对话框，从中选择一种排序方式，单击不同排序方式时，“算法描述”中简要介绍了这种算法。

单击“确定”按钮返回到主窗口，主窗口中最上方框架控件的标题文字显示当前所选的排序算法。

（3）设置完毕，单击“开始排序”按钮（此按钮在生成数据之前是不可用的），启动排序过程。

若选择了动画方式，红色背景的文本框表示当前正在比较的元素，黄色的代表已排序的元素，2个运动的文本框表示交换过程。

在排序过程中可以调节水平滚动条的位置来控制演示过程的速度。

排序结束后程序以消息框的形式报告数据交换的次数。

可以使用快捷菜单中的“将数据写入文件”命令将排序后的数据保存到“data.txt”中覆盖原有内容。

（4）选择窗口主菜单中的“颜色设置”命令，主窗口扩大，底部显示“颜色设置”框架，可以对“文本背景色”、“文本前景色”、“已排序元素色”和“交换结点色”进行设置。

再选择此命令，窗口恢复到原来的大小。

（5）选择主菜单中的“退出”命令可退出本程序，程序显示消息对话框予以确认。

解决：利用了Boolean（逻辑变量）定义了一个使程序停止的变量f，然后又定义了一个Pri vate Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long) ，声明sleep函数，可以使程序暂停一段时间，最后用时钟（timer）来设定所需暂停的随机时间（s）。

注意ti mer函数设置时的interval值，以毫秒为单位，1000ms=1s。

2、问题：消息对话框（msgbox）的形式，及msgbox函数的返回值如何的选取，设置。

解决：在对“停止”按钮编码时，一开始未给msgbox赋值，导致程序不起作用，后来赋值后，采用了msgbox函数里的vbyes与vbno，采用了if...then...else...但程序无法退出，最后只对vbno做了代码编制，退出程序则采用了“unload”函数，最后程序终于调试成功。

3、问题：动态演示如何演变，交换次数无法得到。

解决：采用timer函数，以时间来对它进行控制，也可以拖得滚动条来控制它动态演示时的速度。

解决：设计到了窗体编辑器，及弹出菜单所使用的方法PopupMenu。

学习vb首先就是要对所有常用函数了如指掌，这样在编程的时候才能够很快想到并用对地方，做这个程序设计的一开始，简直是一头雾水，无从下手，后来经过翻书，查找资料，网上资料，等等...终于对所要编的程序有了一定的认识，在同学互相讨论的基础上，终于编出排序演示，但是还存在不足，在动态演示的时候，缺了正在交换文本框的动态形式，但是基本能运行起来，大致的符合了设计任务。

程序中所涉及的内容很多，有比较法排序，插入法排序，冒泡发排序，选择法排序，集合了所有的排序，以前对排序的编程就有点不理解，因为它很绕，真正理解它真的有点困难。

还有一些我们vb书上第七章的一些窗体编辑器，快捷菜单的做法，定时器的编码，这些更加巩固了我对这些知识的理解，通过这几天对vb的深入研究，发现其实慢慢的对vb产生了兴趣，从以前的没兴趣到产生兴趣，这是一种好的现象，兴趣是最好的老师，相信我会越学越好的。
