VBA学习总结

在中断模式下（ctrl+Break键），可以做：

1.执行    工具----选项----编辑器----勾选“自动显示数据提示”

则当用鼠标悬停在变量或表达式上时，会出现提示窗口，显示其名称和值！

2.在监视窗口查看某些表达式的值，方法是：先用鼠标拖黑以选中表达式，再执行   调试----添加监视，出现“添加监视”对话框。

3.在代码窗口中选中表达式----按shift+F9----出现”快速监视“对话框，显示该表达式的上下文，表达式及其值。

4.按ctrl+G，出现"立即窗口”。它主要有4个作用：

（1）.打印信息

在窗口中输入Debug.Print 表达式1；表达式2......，即可以显示各表达式的值！

2.可以给变量或属性赋值！

例如：Form1.BackColor＝255

          MaxRows＝50

3.可以测试过程

在此窗口中可以直接输入过程名称和实参以便调用过程。

例如：

       MySub 2*i

4.可以检查错误号

例如：输入

  Error 11

按下回车键时，在此窗口中显示11号错误的信息。我常用这个方法来检查错误号！

断点

在设计和中断模式下都可以设置断点，当程序执行到断点语句时，则中断执行，这时处于中断模式！

1.设置断点

在代码窗口，用鼠标点击左边区使之出现黑点，代表已经设置断点！也可以把光标移动到选定语句上，按F9.

断点语句以粗体字表示，颜色可以由：  工具---选项---编辑器格式---代码颜色----“断点点文本”选项设定！



2.撤销断点：

调试----清除所有断点（ctrl+shift+F9)

3.使用Stop语句

关闭项目时，断点不被保存，下次调试时需要重新设置。

如果多次调试，最好的方法是使用Stop语句，每当遇到它，程序进入中断模式。

Stop语句可以保存在代码中，测试完后可以全部取消！


监视窗口可以监视表达式，“快速监视”窗口也可以显示表达式的值。

立即窗口对表达式求值，给变量和属性赋值。

本地窗口显示局部变量的当前值。例如下图自己定义的变量：





单步执行调试程序：

1.调试----逐语句(按快捷键是F8)

2.在逐语句执行过程中，遇到调用的过程，不想进入其中停留，按shift+F8,可以“逐过程”执行而不进入！

3.跳出过程

调试----跳出（快捷键是ctrl+shift+F8),可以运行当前过程剩余语句代码，转到调用该过程语句的下一个语句去！

4.执行特定的语句块

这是很重要的一个方法，常用到：在中断模式下，把光标移到要执行的语句行处，执行   调试---设置下一条语句，

用它可以设置下次要执行的语句。再把光标移到要停止的语句处，执行  调试----运行到光标处（快捷键是ctrl+F8)，则可以运行到该语句处！

这种方法的优点是可以绕过不想执行的语句块（例如你明确知道某个有问题的语句）。





调用堆栈：应用程序处于中断模式时，显示已被调用过的过程！

1.怎么显示调用堆栈的对话框：视图---调用堆栈（快捷键是ctrl+L)

2.跟踪嵌套过程

在VBA过程中，常常有调用另外某个或某几个过程，模块，窗体。

可以用“调用堆栈”从下往上显示已活化过程的项目名称，模块或窗体名称和过程名称。

操作方法是：ctrl+L  ----用鼠标选中某个过程-----显示。

这时，代码窗口显示出该过程，光标处于即将调用下一个过程的调用语句处。

此时，按（shift+F9）用“快速监视”或（ctrl+G）立即窗口，可以显示有关变量！

3.用“调用堆栈”来检查过程调用自身的能力



使用UltreEdit之类的十六进制编辑程序打开.XLS文件，在文本模式下查找“[Host Extender Info]”(也可只查Host)，切换到十六进制模式，将前面的“DBP＝"XXXXXXX...”的DBP关键字改成CBP，将“GC＝"XXXXXXX...”的GC关键字改成CC，使Excel不能识别此二项！存盘即可！！！

　　用Excel打开此文件，忽略错误提示，进入VBA编辑器，嘿嘿，密码没有了！做一次存盘操作即可修复错误提示。

    Access的VBA工程密码采用无法破解！


Private Sub CommandButton1_Click()
CommandButton1.Height = CommandButton1.Height * 1.1
CommandButton1.Width = CommandButton1.Width * 1.1
End Sub


VBA如何获取excel活动工作表中所有的chart图表名字,并activate?

MS 2009-10-22 20:15:06 阅读336 评论0   字号：大中小 订阅

For i = 1 To ActiveSheet.ChartObjects.Count

    MsgBox ActiveSheet.ChartObjects(i).Name

Next

ActiveSheet.ChartObjects(1).Activate

ActiveSheet.ChartObjects("Chart 1").Activate



请看下面的操作步骤：我就是用这个办法破译excel表中的密码的，你也试一试吧

1\打开文件
2\工具---宏----录制新宏---输入名字如:aa
3\停止录制(这样得到一个空宏)
4\工具---宏----宏,选aa,点编辑按钮
5\删除窗口中的所有字符(只有几个),替换为下面的内容:(复制吧)
6\关闭编辑窗口
7\工具---宏-----宏,选AllInternalPasswords,运行,确定两次,等2分钟,再确定.OK,密码完全被你看见了!!
内容如下:
