实验三利用记事本等编制程序,.

实验三：利用记事本等编制程序，将程序导入并利用模拟功能进行轨迹检验一、使用记事本或写字板，编写简单零件的数控车床加工程序对几何形状简单、单一的切削路线,如：外径、内径、端面的切削,若加工余量较大,刀具常常要反复地执行相同的动作,才能达到工件要求的尺寸。

要完成上述加工,在一个程序中就要写入很多的程序段,为了简化程序,减少程序所占内存,数控机床设有各种固定循环指令,只需用一个指令,一个程序段,便可完成一次乃至多次重复的切削动作。

轴向（圆柱或圆锥）切削循环指令(G90)如图3-1所示,刀具从循环起点开始按矩形循环,其加工顺序按1,2,3,4进行,最后又回到循环起点。

图中虚线表示按R快速移动,点划线表示按F指定的工件进给速度移动。

图3-1（a）和（b）分别为圆柱或圆锥切削循环示意图。

(1)圆柱面切削循环指令格式：G90 X(U)- Z(W)- F-；(2)圆锥面切削循环指令格式：G90 X(U)- Z(W)- I- F-；功能：进行外圆及内孔直线加工和锥面加工循环,可以简化编程。

其中：X、Z为切削终点坐标；U、W为切削终点相对于循环起点坐标值的增量；I为工件加工锥面大小端直径差的1/2,当锥面的起点坐标大于终点坐标时为正,反之为负；F为切削进给速度。

注意事项如下。

(1)使用循环切削指令,刀具必须先定位至循环起点,再执行循环切削指令,且完成一循环切削后,刀具仍回到此循环起点。

(2)G90是模态指令。

一旦规定,以下程序段一直有效,在完成固定切削循环后,用另一个G代码来取消。

格式中的I(R)值在圆柱切削时是不用的,在圆锥切削时才要用,这一点,我们可从图3-1中清楚看到。

（a）（b）图3-1 轴向（圆柱或圆锥）切削循环指令G90（a）（b）图3-2 轴向（圆柱或圆锥）切削循环指令G90应用如图3-2(a)所示, 加工余量(Z向)为:30mm,如果进刀量为5mm（直径测量）,就分3次循环。

设循环起点为A点(50,52)。

C_实验-记事本(带源码)

记事本实验报告一、实验目的创建一个Windows窗体应用程序，实现记事本的基本功能，具体包括新建文件、打开文件、保存文件、查找等功能。

该实验的目的是掌握：（一）窗体程序的开发（二）常用控件的使用（三）常用事件的处理（四）对话框的设计和使用（五）文件访问的基本方法二、实验内容（一）主窗口Form1图1 主窗口主窗口界面如图1所示，功能包括基本编辑操作、主菜单和其它快捷键功能。

1、编辑功能用文本框实现。

2、窗口标题与文件名相一致。

未打开文件时为“无标题”，打开文件(另存为)后为文件名。

3、支持菜单的热键和快捷键。

二者的区别是前者是激活菜单且显示出该菜单项时有效，后者在任何时候有效。

4、实现新建、打开、保存和查找功能。

5、支持F3（查找下一个）。

ActionScript编程综合实例：简单记事本程序

ActionScript编程综合实例：简单记事本程序Windows操作系统自带有记事本程序，用户可以在记事本中输入文字，并可设置这些文字的字体、大小、颜色等属性。

其实，在Flash 中通过ActionScript代码也可以制作简单地记事本程序，如图19-1所示。

图19-1 简单记事本程序制作过程：（1）新建550×400像素的空白文档，将背景素材图像导入到舞台，并将ComboBox 和ColorPicker 组件拖入到【库】面板中，如图19-2所示。

图19-2 拖入组件（2）在舞台的下面绘制两个大小相近的圆角矩形，并设置其Alpha 值分别为“60%”和“50%”，如图19-3所示。

图19-3 绘制圆角矩形（3）在相同文件夹中新建名称为Text 的ActionScript 文件，并在该文件中使用import 语句导入所需的类，以及创建包、Text 类和Text()主函数，如下所示。

package {import flash.display.Sprite; import flash.text.TextField; importflash.text.TextFieldAutoSize;import flash.text.TextFormat; import flash.text.TextFieldType; import boBox; import flash.events.Event; import fl.controls.ColorPicker;public class Text extends Sprite {var content_txt:TextField; //用于显示文本内容的文本字段var color_txt:TextField; //用于显示颜色值的文本字段public function Text() { //主函数体 } } }（4）创建名称为createTitle 的函数，该函数创建一个用于显示标题的文本字段，并为其定义文本样式，如下所示。

用记事本编写整人小程序

不需要任何编程基础，不需要任何编程软件，只需使用电脑里自带的记事本软件就可以轻松编写出整人的小程序，甚至是病毒。

首先，单击右键，新建一个文本文档，输入：msgbox"你是猪！"然后，点击文件->另存为->保存类型：所有文件->文件名xxxx.vbs，名字随便起，但一定要记得把后缀名改为 .vbs。

然后打开刚保存的xxxx.vbs哈哈，很好玩吧，双引号里的内容”你是猪！”可以随意更改，但双引号一定要用英文输入法来写。

嗯，下面正式开始整人。

按照前面说的，在记事本上输入如下图，并保存为55.vbs。

其中wscript.Sleep 500为停留500毫秒，可随便更改下面这段代码就是一个启动关机程序的东东，300这个数是指300秒倒计时，这个数字也可以随便改，这段代码也可以独立保存出来作为一个关机程序dim WSHshellset WSHshell = wscript.createobject("wscript.shell")WSHshell.Run "cmd.exe /c shutdown -s -t 300"打开这个文件，如果你点击“是”，你就会进入一个死循环中，就是不断地弹出对话框。

解决方法是按下Alt+Ctrl+Delete键，选择“进程”，把wscript.exe结束掉。

如果点击“否”，则进入关机倒计时，解决方法是点击“开始”->“运行”,在对话框里输入shutdown -a ,再点击“确定”即可。

最后嘛，把这文件创建桌面快捷方式，然后把图标换了，换成QQ什么的，你懂的，呵呵。

当然，这种VBS编程还有很多好玩的地方，比如病毒，我也收藏有几个，由于我是一等一的良好市民，就不写上来了。

最后再送上一个程序：dim adoa=inputbox("输入123，否则关机。

")if a="123" thenmsgbox" 很遗憾，你中招了，这是整人程序，你就等着关机吧"WSHshell.Run "cmd.exe /c shutdown -s -t 300"wscript.sleep 1000exit doelsemsgbox"乖点，输入123"end ifloop。

记事本的程序设计及代码示例

记事本的程序设计及代码示例记事本是一种常见的应用程序，用于记录和编辑文本内容。

在本文中，我们将探讨记事本的程序设计，并给出一个基于Python语言的代码示例。

一、程序设计思路在设计记事本程序时，我们需要考虑以下几个方面：1. 用户界面设计：记事本的用户界面应简洁直观，方便用户输入和编辑文本内容。

可以采用菜单栏、工具栏和文本区域等组件，让用户可以进行打开、保存、复制、粘贴、查找替换等操作。

2. 功能设计：记事本应具备基本的文本编辑功能，如插入、删除、复制、粘贴和撤销等。

此外，还可以添加其他高级功能，如自动保存、自动换行、字体调整以及批量替换等。

3. 文件操作：记事本需要支持文件的打开和保存功能。

用户可以通过打开功能选择要编辑的文本文件，保存功能可以将编辑的内容保存为文件。

同时，还可以支持文件拖拽和快捷键操作。

二、代码示例下面是一个基于Python语言的记事本代码示例：```pythonimport tkinter as tkfrom tkinter import filedialogwindow = ()window.title("记事本")# 创建文本区域text_area = tk.Text(window)text_area.pack()# 打开文件函数def open_file():file_path = filedialog.askopenfilename() if file_path:with open(file_path, 'r') as file:text_area.delete(1.0, tk.END)text_area.insert(tk.END, file.read()) # 保存文件函数def save_file():file_path = filedialog.asksaveasfilename() if file_path:with open(file_path, 'w') as file:file.write(text_area.get(1.0, tk.END))menu_bar = tk.Menu(window)window.config(menu=menu_bar)# 添加文件菜单file_menu = tk.Menu(menu_bar, tearoff=False)menu_bar.add_cascade(label="文件", menu=file_menu)file_menu.add_command(label="打开", command=open_file)file_menu.add_command(label="保存", command=save_file)file_menu.add_separator()file_menu.add_command(label="退出", command=window.quit)# 运行主窗口window.mainloop()```以上代码使用Python的tkinter库创建了一个简易的记事本应用程序。

记事本编程序

看点:你知道吗？为什么现在脚本病毒如此猖獗？你知道吗？编写一个脚本病毒其实非常简单！你知道吗？根本不懂编程的你只要稍加操练也能编出不错的软件！Windows脚本就像魔法卷轴般神奇，编写起来也很容易。

或许这句话并没有凭据，但把玩几个小时，比如看完这期专题并且亲自演练一下，相信你会同意我的说法。

当然，有一点编程经验当然更好，因为你会发现很多知识都是相通的。

快来吧！编写你的第一个脚本打开"记事本"，按照如图1所示输入(图1 你的第一个脚本程序)，并把这个文件保存为HelloWorld.vbs，接着双击它，你就会看到一个跳出来的对话框，上面写着"Hello World!"，点击"确定"按钮就可以结束这个脚本。

恭喜！你已经完成了第一个脚本程序！一、魔法的前言:什么是脚本1.什么是编程语言许多朋友一听到什么编程语言就头大，其实理解起来并不困难，说得通俗些，编程语言就是类似于汉语、英语的语言，只不过它们是用来和电脑沟通的语言，程序员就相当于你和电脑之间的翻译，他们会把你需要实现的功能用相应语言告诉电脑，让它来执行，如果某个功能会有非常多人用到，那么程序员就把它翻译成成一个文件，这就是程序。

因此，你只要掌握了编程语言的基本命令、规范、用法，那么就能轻松编出程序，当然，电脑在理解语言方面有些弱智，或者说是非常严谨，你不能说错一个单词或把语句顺序搞混，否则它就无法理解你的话，无法执行你的命令或做出完全相反的事情。

2.什么是Windows脚本语言首先，Windows脚本语言也是一种编程语言，也有自己专门的命令词汇、规范、用法，你只要按照自己的要求把命令写进去，那么Windows就会直接执行。

只不过相对于Java、C++等编程语言要简单得多，也就是即使以前根本没有编程经验的普通人也能很容易地在较短时间内学习并掌握。

同时，Windows脚本语言是完全免费的，不像一套Visual Basic或Delphi，动辄几千人民币，它不花一分钱。

跟我学做记事本-编程实例用VB做一个记事本实在不很复杂，我们完全可以通过向导来很方便地做出来。

但本文只打算讨论用手动方法制作记事本，旨在向VB初学者展示：学VB原来是如此容易！通过阅读、研究本文并按本文所述进行尝试，初学者将学到很多东西,如怎样使用RichText 控件来打开和保存文件，怎样制作菜单、工具栏和状态栏以及如何对其编写代码等。

第一章让我们的记事本马上运行急于求成是初学者共有的心愿。

那好，请按如下三个步骤做，我们的愿望立即就可以实现！步骤一：绘制界面。

新建一个标准EXE工程，将其Caption属性改为“超级记事本”，点击Icon属性给它找个合适的Icon图标。

单击菜单“工程”-“部件”，在弹出的“部件”对话框里找到MicrosoftRichText Box 6.0和公共对话框Microsoft Common Dialog 6.0并选中它们，单击“确定”按钮。

这时左边的工具栏上出现了我们刚才新添的两个控件了。

在窗体上绘制RichTextBox和Commn Dialog，其中RichText Box的大小和位置可不用理睬，我们将在代码中处理它，当然，有必要把它的ScrollBar属性设为2-rtfVertical，这样在打开和编辑文件时垂直滚动条才可用。

步骤二：编辑菜单。

按Ctrl+E调出菜单编辑器，我们来做如下几个菜单：一.文件菜单：文件（第一层）mnuFile新建（第二层）mnuNew打开（第二层）mnuOpen保存（第二层）mnuSave- （第二层）mnuFileSep (分隔线）退出（第二层）mnuExit二.编辑菜单：编辑（第一层）mnuEdit复制（第二层）mnuCopy剪切（第二层）mnuCut粘贴（第二层）mnuPaste第二层）mnuEditSep （分隔线）全选（第二层）mnuSelecAll三.搜索菜单：搜索（第一层）mnuSearch查找（第二层）mnuFind查找下一个（第二层）mnuFindOn四.帮助菜单：帮助（第一层）mnuHelp使用说明（第二层）mnuUsage关于（第二层）mnuAbout(注：各菜单项的快捷键请自行设置)好了，其它的菜单项以后再根据需要添加。

现在进入：步骤三：编写代码。

'声明查找变量Dim sFind As String'声明文件类型Dim FileType, FiType As String'初始化程序Private Sub Form_Load()'设置程序启动时的大小Me.Height = 6000Me.Width = 9000End Sub'设置编辑框的位置和大小Private Sub Form_Resize()On Error Resume Next '出错处理RichTextBox1.Top=20RichTextBox1.Left=20RichTextBox1.Height = ScaleHeight-40 RichTextBox1.Width = ScaleWidth-40 End Sub'新建文件Private Sub mnuNew_Click()RichTextBox1.Text = "" '清空文本框FileName = "未命名"Me.Caption = FileNameEnd Sub'打开文件Private Sub mnuOpen_Click()CommonDialog1.Filter = "文本文档(*.txt)|*.txt|RTF文档(*.rtf)|*.rtf|所有文件(*.*)|*.*" CommonDialog1.ShowOpenRichTextBox1.Text = "" '清空文本框FileName = CommonDialog1.FileNameRichTextBox1.LoadFile FileNameMe.Caption = "超级记事本：" & FileNameEnd Sub'保存文件Private Sub mnuSave_Click()CommonDialog1.Filter = "文本文档(*.txt)|*.txt|RTF文档(*.rtf)|*.rtf|所有文件(*.*)|*.*" CommonDialog1.ShowSaveFileType = CommonDialog1.FileTitleFiType = LCase(Right(FileType, 3))FileName = CommonDialog1.FileNameSelect Case FiTypeCase "txt"RichTextBox1.SaveFile FileName, rtfText Case "rtf"RichTextBox1.SaveFile FileName, rtfRTF Case "*.*"RichTextBox1.SaveFile FileNameEnd SelectMe.Caption = "超级记事本：" & FileName End Sub'退出Private Sub mnuExit_Click()EndEnd Sub'复制Private Sub mnuCopy_Click() Clipboard.ClearClipboard.SetText RichTextBox1.SelText End Sub'剪切Private Sub mnuCut_Click() Clipboard.ClearClipboard.SetText RichTextBox1.SelText RichTextBox1.SelText = ""End Sub'全选Private Sub mnuSelectAll_Click()RichTextBox1.SelStart = 0RichTextBox1.SelLength = Len(RichTextBox1.Text) End Sub'粘贴Private Sub mnuPaste_Click()RichTextBox1.SelText = Clipboard.GetTextEnd Sub'查找Private Sub mnuFind_Click()sFind = InputBox("请输入要查找的字、词：", "查找内容", sFind)RichTextBox1.Find sFindEnd Sub'继续查找Private Sub mnuFindOn_Click()RichTextBox1.SelStart = RichTextBox1.SelStart + RichTextBox1.SelLength + 1RichTextBox1.Find sFind, , Len(RichTextBox1)End Sub'使用说明Private Sub mnuReadme_Click()On Error GoTo handlerRichTextBox1.LoadFile "Readme.txt", rtfText '请写好Readme.txt文件并存入程序所在文件夹中Me.Caption = "超级记事本：" & "使用说明"Exit Subhandler:MsgBox "使用说明文档可能已经被移除，请与作者联系。

点击菜单“文件”-“生成XXX.EXE”，回到桌面运行我们的记事本看看，是不是颇有成就感？当然，这样的记事本还比较粗糙,我们还需要做些工作，请看下一章。

第二章美化程序界面多数字处理软件都有工具栏和状态栏。

工具栏和状态栏除了能美化我们的程序使其更具有专业性质外，还给用户带来操作上的便利。

现在我们就来做一做这两样东西。

一.工具栏(一)制作工具栏单击“工程”-“部件”，选中Microsoft Windows Common Control 6.0并确定。

这时，我们要用到的控件就出现在左边的工具栏上了。

要做工具栏，首先需要一个叫ImageList的控件来装载图像。

在程序界面上添加它，然后右键单击此控件，左键单击“属性”，弹出“属性页”对话框的“图像”，再单击“插入图片”就可以一次性装载图片了（如不满意，以后还可以添加）。

图片可在C:MicrosoftVisual StudioCommonGraphicsBitmapsTlBr_W95下选择(这里假设你的VB安装在C盘下)。

注意了：在插入图片时给每一张图片注明关键字，以便在引用图片时不至于混乱。

如插入“新建”的图片，我们在“关键字”栏注明“New”。

图片有了，接下来在程序界面添加工具栏(ToolBar)。

添加后工具栏就出现在菜单下面，右键单击它，选择“属性”，在弹出的“属性页”对话框中的“通用”项作些设置，主要如下两项：1.“图像列表”：选择ImageList12.“样式”：根据喜爱选择1-trbStandard或者2-trbFlat继续点击“属性页”的“按钮”选项，插入若干按钮。
