Click Here to Learn VBA I am currently revamping this site, and transferring all the VBA coding related tips, questions and answer links to this page, from this page: Simply Access Tips Index So if you are sure there should be something here that isn't, check out the Index page above, or contact me on my 'Contact Page' to put forward your suggestion and I will do my best to include it.
Choose that button the instant you complete the actions that you want to record. Choose cell B1 and type the programmer's classic first string: Hello World. Stop typing and look at the Stop Recording button; it is grayed out because Excel is waiting for you to finish typing the value in the cell. Choose cell B2 to complete the action in cell B1, and then choose Stop Recording. Be aware of the similarities to the earlier code snippet that selected text in cell A1, and the differences.
In this code, cell B1 is selected, and then the string "Hello World" is applied to the cell that has been made active. The quotes around the text specify a string value as opposed to a numeric value.
Remember how you chose cell B2 to display the Stop Recording button again? That action shows up as a line of code as well. The macro recorder records every keystroke. The lines of code that start with an apostrophe and colored green by the editor are comments that explain the code or remind you and other programmers the purpose of the code.
VBA ignores any line, or portion of a line, that begins with a single quote. Writing clear and appropriate comments in your code is an important topic, but that discussion is out of the scope of this article. Subsequent references to this code in the article do not include those four comment lines.
When the macro recorder generates the code, it uses a complex algorithm to determine the methods and the properties that you intended. If you do not recognize a given property, there are many resources available to help you. For example, in the macro that you recorded, the macro recorder generated code that refers to the FormulaR1C1 property. Not sure what that means?
Be aware that Application object is implied in all VBA macros. The code that you recorded works with Application. Select FormulaR1C1 in the recorded macro and press F1. The Help system runs a quick search, determines that the appropriate subjects are in the Excel Developer section of the Excel Help, and lists the FormulaR1C1 property. You can choose the link to read more about the property, but before you do, be aware of the Excel Object Model Reference link near the bottom of the window.
Choose the link to view a long list of objects that Excel uses in its object model to describe the Worksheets and their components. Choose any one of those to see the properties and methods that apply to that particular object, along with cross references to different related options. Many Help entries also have brief code examples that can help you.
For example, you can follow the links in the Borders object to see how to set a border in VBA. The Borders code looks different from the recorded macro. One thing that can be confusing with an object model is that there is more than one way to address any given object, cell A1 in this example. Sometimes the best way to learn programming is to make minor changes to some working code and see what happens as a result. Try it now. Open Macro1 in the Visual Basic Editor and change the code to the following.
You do not need to save the code to try it out, so return to the Excel document, choose Macros on the Developer tab, choose Macro1 , and then choose Run. Cell A1 now contains the text Wow! You just combined macro recording, reading the object model documentation, and simple programming to make a VBA program that does something. The VBA community is very large; a search on the Web can almost always yield an example of VBA code that does something similar to what you want to do. If you cannot find a good example, try to break the task down into smaller units and search on each of those, or try to think of a more common, but similar problem.
Starting with an example can save you hours of time. That does not mean that free and well-thought-out code is on the Web waiting for you to come along.
In fact, some of the code that you find might have bugs or mistakes. The idea is that the examples you find online or in VBA documentation give you a head start. Remember that learning programming requires time and thought. Before you get in a big rush to use another solution to solve your problem, ask yourself whether VBA is the right choice for this problem. Programming can get complex quickly.
It is critical, especially as a beginner, that you break the problem down to the smallest possible logical units, then write and test each piece in isolation. If you have too much code in front of you and you get confused or muddled, stop and set the problem aside. When you come back to the problem, copy out a small piece of the problem into a new module, solve that piece, get the code working, and test it to ensure that it works.
Then move on to the next part. There are two main types of programming errors: syntax errors, which violate the grammatical rules of the programming language, and run-time errors, which look syntactically correct, but fail when VBA attempts to execute the code. Although they can be frustrating to fix, syntax errors are easy to catch; the Visual Basic Editor beeps and flashes at you if you type a syntax error in your code.
For example, string values must be surrounded by double quotes in VBA. To find out what happens when you use single quotes instead, return to the Visual Basic Editor and replace the "Wow! If you choose the next line, the Visual Basic Editor reacts. The error "Compile error: Expected: expression" is not that helpful, but the line that generates the error turns red to tell you that you have a syntax error in that line and as a result, this program will not run.
Runtime errors are harder to catch because the programming syntax looks correct, but the code fails when VBA tries to execute it. For example, open the Visual Basic Editor and change the Value property name to ValueX in your Macro, deliberately introducing a runtime error since the Range object does not have a property called ValueX.
Go back to the Excel document, open the Macros dialog box and run Macro1 again. You should see a Visual Basic message box that explains the run-time error with the text, "Object doesn't support this property of method. When you return to the Visual Basic Editor, it is in a special debug mode that uses a yellow highlight to show you the line of code that failed.
As expected, the line that includes the ValueX property is highlighted. You can make changes to VBA code that is running, so change ValueX back to Value and choose the little green play button underneath the Debug menu. The program should run normally again. It is a good idea to learn how to use the debugger more deliberately for longer, more complex programs.
At a minimum, learn a how to set break-points to stop execution at a point where you want to take a look at the code, how to add watches to see the values of different variables and properties as the code runs, and how to step through the code line by line. These options are all available in the Debug menu and serious debugger users typically memorize the accompanying keyboard shortcuts.
To open the Developer Reference that is built into Office Help, open the Help reference from any Office application by choosing the question mark in the ribbon or by pressing F1. Then, to the right of the Search button, choose the dropdown arrow to filter the contents. Choose Developer Reference. If you do not see the table of contents in the left panel, choose the little book icon to open it, and then expand the Object Model Reference from there.
Time spent browsing the Object Model reference pays off. After you understand the basics of VBA syntax and the object model for the Office application that you are working with, you advance from guesswork to methodical programming. Of course the Microsoft Office Developer Center is an excellent portal for articles, tips, and community information. All programmers get stuck sometimes, even after reading every reference article they can find and losing sleep at night thinking about different ways to solve a problem.
Fortunately, the Internet has fostered a community of developers who help each other solve programming problems. Any search on the Web for "office developer forum" reveals several discussion groups. You can search on "office development" or a description of your problem to discover forums, blog posts, and articles as well. If you have done everything that you can to solve a problem, do not be afraid to post your question to a developers forum.
These forums welcome posts from newer programmers and many of the experienced developers are glad to help. SQL uses a limited range of "[gs keyword]s" combined with information you supply, such as table names, field names and criteria, to construct essentially simple although sometimes long statements detailing what you want the program to do with your data.
SQL can often be used alone, for example when setting the RecordSource property of a form or report in design view, or when working in the SQL View of the Access query design window. Its aim is explain the rules of SQL and to encourage you to use good code-writing practice and to avoid the pitfalls and problems that can occur. The way you write your code is a very personal thing so I'm going to show you how I do things, using some techniques I have learnt from others and some I've figured out myself.
VBA is a very flexible language and there are often many different ways in which VBA can achieve the same [gs task]. SQL on the other hand is a very precise and inflexible language. Everything has to be just so, but it has the advantage of also being very simple. Different developers have their own ways of doing things and this is reflected in their coding style. What you will see here is the way I like to write my code. SQL statements can also be quite long, and for that reason they are usually assigned to text variables so that they are easier to handle.
Something like this Of course you could do away with the variable and apply the SQL directly, like this:. But, as you will see in the later tutorials building an SQL statement might involve several stages and many lines of code so I usually opt to store it in a variable. In case you haven't already noticed, I always write the SQL keywords in capitals upper case. Access doesn't care if you do this or not but you will find your code much easier to read and understand if you do.
Compare these two statements:. Okay, I'm getting picky here, but I always put square brackets around field names. Access only demands that you do this when your field names contain spaces. The brackets tell Access that all the words in the field name belong together. They also tell Access that "this is a field name" and so allows you to use otherwise reserved words for the names of fields such as [Date] which is also the name of a function without causing conflicts.
But I do this for another reason too. I know that if I see some text in square brackets I know it's a field name, whether it has spaces in it or not I like to write each clause of the SQL statement on a separate line. This makes long statements much easier to read and edit Don't forget that each line must have both opening and closing quotes.
The statement itself needs to be enclosed in quotes because it is a VBA text [gs string]. If you use the same type of quote mark for each Access will get confused. Look at this example Compare the two examples below.
In the first example the VBA sees two text strings enclosed by double quote marks, and between them a word it doesn't know Paris so it generates an error. But when the quote marks are alternated as shown in the second example, the problem doesn't arise. The VBA sees a text string enclosed by double quotes, inside which is some more text enclosed in single quotes. I working with multiple sets of quotes gets confusing, you can always use the ASCII character code for the double quote mark - Chr 34 - instead.
There is an example of this in the next section. Some of these rules are essential, others are just my way of doing things and that of many other database developers. Follow them and you will write good code that is easy to read and to debug.
