巧妙运用PPT制作演讲比赛评分系统

1、精选优质文档-倾情为你奉上巧妙运用PPT制作演讲比赛评分系统准备工作：在C盘新建一文件夹，命名为“考试评分”。用于存放参赛人员的相关信息，其中Name.txt中保存着各参赛人员名字（事先准备好Name.txt，每位参赛人员占一行）。制作过程：1.界面设置打开PowerPoint 2003新建一幻灯片，点击“视图工具栏控件工具箱”打开“控件工具箱”。在工具箱中使用“图像控件”来插入八位语文教师的照片，分数可以用“文本框”来表示，再插入两个“命令按钮”进行操作，分别为“清空”和“最终得分”按钮。放置好控件之后再调整各控件的属性并美化界面（见图1）。评委打分的文本框名称为Text1，Text2，Te

2、xt8，“最终得分”按钮的名称为CommandTotal，第二张幻灯片用来显示最后得分，名称为TotalScore。2.全局变量设置打开VBA编辑器（见图2）输入如下代码：Const Path$ = "C:考试评分"'指定得分的统计文件路径Dim sum As Single'全局变量总分Dim AverageScore As Single'全局变量平均得分Dim GroupNum As Integer'全局变量记录组次Private Sub CommandButton1_Click()'清空得分Text1.Text = "&

6、Visual Basic中点击“插入模块”来建立评奖模块，再写入如下代码：Const Counter = 6'如评一等奖1名，二等奖2名，三等奖3名，故Counter设为6Public StrName(Counter) As StringPublic SngScore(Counter) As SinglePublic Sub ReadDataInp()'读取得分文件，并对得分加以排序On Error GoTo erOpen Path$ & "InpName.txt" For Input As #1For i = 1 To CounterInput #
