For example you cannot save macros in a standard Word document with a. When you open a. Examine the settings and options in the Trust Center on all Office applications. The default setting disables macro from running, but warns you that macros have been disabled and gives you the option to turn them back on for that document. You can designate specific folders where macros can run by creating Trusted Locations, Trusted Documents, or Trusted Publishers.
The most portable option is to use Trusted Publishers, which works with digitally signed documents that you distribute. For more information about the security settings in a particular Office application, open the Options dialog box, choose Trust Center , and then choose Trust Center Settings. Some Office applications, like Outlook, save macros by default in a master template on your local computer.
Although that strategy reduces the local security issues on your own computer when you run your own macros, it requires a deployment strategy if you want to distribute your macro. When you choose the Macro button on the Developer tab, it opens the Macros dialog box, which gives you access to VBA subroutines or macros that you can access from a particular document or application. Another button on the Developer tab in Word and Excel is the Record Macro button, which automatically generates VBA code that can reproduce the actions that you perform in the application.
Record Macro is a terrific tool that you can use to learn more about VBA. Reading the generated code can give you insight into VBA and provide a stable bridge between your knowledge of Office as a user and your knowledge as a programmer. The only caveat is that the generated code can be confusing because the Macro editor must make some assumptions about your intentions, and those assumptions are not necessarily accurate. Open Excel to a new Workbook and choose the Developer tab in the ribbon.
Choose Record Macro and accept all of the default settings in the Record Macro dialog box, including Macro1 as the name of the macro and This Workbook as the location. Choose OK to begin recording the macro. Note how the button text changes to Stop Recording. 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. Selecting a language below will dynamically change the complete page content to that language. KB Articles: KB Security bulletins: MS Warning: This site requires the use of scripts, which your browser does not currently allow.
