vb实验八综合实验答案
实验八综合实验（4个学时）一、实验目的1．掌握常用控件的使用。
2．掌握下拉菜单的设计方法。
3．掌握创建多重窗体程序的有关技术。
4．了解常用事件及过程。
5．掌握顺序文件的打开、关闭和读写操作。
6．掌握三种鼠标事件的用法。
7．综合运用所学的知识，编写具有可视化界面的应用程序。
二、实验内容利用菜单、对话框、选择结构语句、循环结构语句、多窗体、常用控件、过程等知识点进行综合程序设计。
具体要求：1．在主窗体上，设计下拉式菜单：数值计算画图与动画顺序文件退出n! 编写画图程序读写古诗1+3+…+99 S6.1（说明：S6.1表示实验六的第1题）2．分别单击菜单项n!( 要求从键盘键入n的值)，1+3+5+….99时，要求在主窗体中设置Label1显示题目，Label2显示结果界面如下图。
1）Form1中的代码设计如下：Private Sub accumulate_Click()Dim i As Integer, sum As IntegerFor i = 1 To 99sum = sum + iNext iLabel1.Caption = "1+2+3+4+…+99="Label2.Caption = sumEnd SubPrivate Sub factorial_Click()Dim a As IntegerLabel1.Visible = TrueLabel2.Visible = Truea = InputBox("请输入n的值", "注意")La bel1.Caption = "1×2×…×" & a & "="s = 1For i = 1 To as = s * iNext iLabel2.Caption = sEnd Sub2）将从键盘上输入n = 9时的运行界面剪切下来粘贴在下面。

因此，当我们着手做一个实验的时候，必须明确实验的目的，以保证达到课程所指定的基本要求。
在写实验报告时，要进一步确认是否达到了预期的目的。
（2）实验内容实验的目的是要通过解决一些具体问题来达到的。
在书中，每一部分都安排了多个实验题目，根据教学安排、进度、实验条件、可提供的机时、学生的基础等因素，可以选择其中的几个或全部。
因此，在实验报告中，实验内容是指本次实验中实际完成的内容。
在每一个实验题目中，一般都提出一些具体要求，其中有些具体要求是为了达到实验目的而提出的，不仅有具体的实验题目，还应包括具体要求。
（3）程序设计说明包括算法设计思路，必要的流程图，界面设计说明、使用模块及变量的说明等。
（4）源程序代码Visual Basic的源程序包括界面设计和代码。
程序设计的产品是程序，它应与算法或流程图相一致，要与用户界面设计一致。
