Excel VBA - Programming

This section is for users who want to get the most out of Excel VBA. Excel VBA Programming is not difficult, but you do need to know the keywords used in Excel VBA.

1. Variables: Excel VBA uses variables just like any other programming language. Learn how to declare and initialize an excel vba variable of type Integer, String, Double, Boolean and Date.
2. String Manipulation: There are many functions in Excel VBA we can use to manipulate strings. In this chapter you can find a review of the most important functions.
3. Calculate: Calculate with Excel VBA and add, subtract, multiply and divide values just like you are used to doing in Excel.
4. If Then Statement: In many situations you only want Excel VBA to execute certain code lines when a specific condition is met. The If Then statement allows you to do this. Instead of multiple If Then statements, you can use Select Case.
5. Cells: Instead of the more common Range object we could also use Cells. Using Cells is particularly useful when we want to loop through ranges.
6. Loop: Looping is one of the most powerful programming techniques. A loop (or For Next loop) in Excel VBA enables you to loop through a range of data with just a few lines of code.
7. Logical Operators: Do you want to execute code in Excel Visual Basic when more conditions are met? Or just one? Or none? Logical operators are what you need! Logical operators such as And, Or and Not are often used in Excel VBA.
8. Range: The Range object which is the representation of a cell (or cells) on your worksheet is the most important object of Excel VBA. It has many properties and methods and they are essential to manipulate the content of your Excel worksheet. In this chapter you will discover the most useful properties and methods of the Excel VBA Range object. They enable you to obtain control over your Excel worksheet.
9. Events: This chapter teaches you how to program workbook and worksheet events. Events are actions performed by users which trigger Excel VBA to execute a macro. For example, when you open a workbook or when you change something on an Excel worksheet, Excel VBA can automatically execute a macro.
10. Array: An Excel VBA array is a group of variables. You can refer to a specific variable (element) of an array by using the array name and the index number.
11. Date and Time: Dates and Times in Excel VBA can be manipulated in many ways. Easy examples are given in this chapter.
12. Function and Sub: The difference between a function and a sub in Excel VBA is that a function can return a value and a sub cannot. In this chapter we will look at an easy example of a function and a sub. Functions and subs become very useful as program size increases.
