Excel VBA Macro Manual Pre lunch Session I. Introduction to VBA Macros

Developed by Micosoft

A tool that helps develop programs that control excel

Macro comes from the work Makros meaning LARGE. II. Objective of developing VBA Macro Codes

Inserting a bunch of Text

Automating a task you perform frequently

Automating repetitive operations

Creating a custom command

Creating a custom button

Developing new worksheet functions III. Introduction to various objects and properties to be used in VBA Language What do you mean by an Object? Most programming languages today deal with objects, a concept called object oriented programming. Although Excel VBA is not a truly object oriented programming language, it does deal with objects. VBA object is something like a tool or a thing that has certain functions and properties, and can contain data. For example, an Excel Worksheet is an object, cell in a worksheet is an object, range of cells is an object, font of a cell is an object, a command button is an object, and a text box is an object and more. In order to view the VBA objects, you can insert a number of objects or controls into the worksheet, and click the command button to go into the code window. The upper left pane of the code window contains the list of objects you have inserted into the worksheet; you can view them in the dropdown dialog when you click the down arrow. The right pane represents the events associated with the objects. Object Properties An Excel VBA object has properties and methods. Properties are like the characteristics or attributes of an object. For example, Range is an Excel VBA object and one of its properties is value. We connect an object to its property by a period(a dot or full stop). The following example shows how we connect the property value to the Range object. Example Private Sub CommandButton1_Click() Range("A1:A6").Value = 10 End Sub

Example Private Sub CommandButton1_Click() Range("A1:A6")= 10 End Sub Cells is also an Excel VBA object, but it is also the property of the range object. So an object can also be a property, it depends on the hierarchy of the objects. Range has higher hierarchy than cells, and interior has lower hierarchy than Cells, and color has lower hierarchy than Interior, so you can write Range("A1:A3").Cells(1, 1).Interior.Color = vbYellow . This statement will fill cells (1,1) with yellow color. Notice that although the Range object specifies a range from A1 to A3, but the cells property specifies only cells(1,1) to be filled with yellow color, it sort of overwrite the range specified by the Range object. Another object is font that belong to the Range object. And font has its properties.For example, Range(A1:A4).Font.Color=vbYellow , the color property of the object Font will result in all the contents from cell A1 to cell A4 to be displayed in yellow color. Sometime it is not necessary to type the properties, Excel VBA IntelliSense will display a drop-down list of proposed properties after you type a period at the end of the object name. You can then select the property you want by double clicking the it or by highlighting it then press the Tab key. IV. The Concept of Variables Variables are like mail boxes in the post office. The contents of the variables changes every now and then, just like the mail boxes. In VBA, variables are areas allocated by the computer memory to hold data. Like the mail boxes, each variable must be given a name. To name a variable in VBA, you have to follow a set of rules, as follows: The Concept of Variables

It must be less than 255 characters

No spacing is allowed

It must not begin with a number

Period is not permitted


Declaring Variables In VBA, one needs to declare the variables before using them by assigning names and data types. There are many VBA data types, which can be grossly divided into two types, namely the numeric data types and non-numeric data types Numeric Data Types Numeric data types are types of data that consist of numbers, which can be computed mathematically with various standard operators such as add, minus, multiply, divide and so on. In VBA, the numeric data are divided into 7 types

Non-numeric Data Types

You can declare the variables implicitly or explicitly. For example, sum=text1.text means that the variable sum is declared implicitly and ready to receive the input in Text1 textbox. Other examples of implicit declaration are volume=8 and label=Welcome. On the other hand, for explicit declaration, variables are normally declared in the general section of the codes' windows using the Dim statement. The format is as follows: Dim variableName as DataType Dim password As String Dim yourName As String Dim firstnum As Integer Dim secondnum As Integer


Dim total As Integer Dim BirthDay As Date You may also combine them in one line, separating each variable with a comma, as follows: Dim password As String, yourName As String, firstnum As Integer. If the data type is not specified, VB will automatically declare the variable as a Variant. For string declaration, there are two possible formats, one for the variable-length string and another for the fixed-length string. However, for the fixed-length string, you have to use the format as shown below: Dim VariableName as String * n where n defines the number of characters the string can hold. For example, Dim yourName as String * 10 mean yourName can hold no more than 10 Characters. Creating a module In general, a VBA module can hold three types of code: Declarations: One or more information statements that you provide to VBA. For example, you can declare the data type for variables you plan to use, or set some other module-wide options. Sub procedures: A set of programming instructions that performs some action. Function procedures: A set of programming instructions that returns a single value (similar in concept to a worksheet function, such as SUM). A single VBA module can store any number of Sub procedures, Function procedures, and declarations. How you organize a VBA module is completely up to you. Some people prefer to keep all their VBA code for an application in a single VBA module; others like to split up the code into several different modules. Its a personal choice. Getting VBA code into a module An empty VBA module is like the fake food you see in the windows of some Chinese restaurants; it looks good but it doesnt really do much for you. Before you can do anything meaningful, you must have some VBA code in the VBA module. You can get VBA code into a VBA module in three ways:

1. Enter the code directly.

2. Use the Excel macro recorder to record your actions and convert them to VBA code

3. Copy the code from one module and paste it into another V. Understanding Macro security and saving a workbook with Macro contents. Macro security is a key feature in Excel 2007. The reason is that VBA is a powerful language so powerful that even a simple macro can do serious damage to your computer. A macro can delete files, send information to other computers, and even destroy Windows so that your system cant even be started. The macro security features in Excel 2007 were created to help prevent these types of problems. To display this dialog box, choose Developer Macro Security. By default, Excel uses the Disable All Macros with Notification section. If you are certain that the workbook comes from a trusted source, click Enable Macros, and the macros will be enabled. Perhaps the best way to handle macro security is to designate one or more folders as trusted locations. All the workbooks in a trusted location


are opened without a macro warning. You designate trusted folders in the Trusted Locations section of the Trust Center dialog box. If you want to find out what the other macro security settings imply, press F1 while the Macro Settings section of the Trust Center dialog box is in view. The Help screen opens up and the subject Enable or disable macros in Office documents is shown in the Help window. VBA Codes Example 'Activating Sheet 1 and Selecting the Cells A1:D10
