Microsoft Access – Introduction | Virtual College.
When you create a new database, you typically begin by creating several database objects such as tables, forms, and reports. Eventually, you reach a point where you have to add some programming to automate certain processes and tie your database objects together. This article helps orient you to the programming tools in Access. What is programming? Use the Command Button Wizard to perform common programming tasks. Understand macros.
Understand VBA code. Convert macros to VBA code. For example, suppose that you have created a form and a report, and you want to add a command button to the form that, when clicked, opens the report. Programming, in this case, is the process of creating a macro or VBA procedure and then setting the command button’s OnClick event property so that clicking the command button runs the macro or procedure. For a simple operation, such as opening a report, you can use the Command Button Wizard to do all the work, or you can turn off the wizard and do the programming yourself.
This can be confusing to Access users because, in Access, the term “macro” refers to a named collection of macro actions that you can assemble by using the Macro Builder. Access macro actions represent only a subset of the commands available in VBA. The Macro Builder gives you a more structured interface than the Visual Basic Editor, enabling you to add programming to controls and objects without having to learn VBA code. You should remember that in Access Help articles, Access macros are referred to as macros.
VBA code is contained in class modules which are part of individual forms or reports and typically contain code just for those objects and in modules which are not tied to specific objects and typically contain “global” code that can be used throughout the database. Objects such as forms and reports and controls such as command buttons and text boxes have various event properties to which you can attach macros or procedures. Each event property is associated with a specific event, such as clicking the mouse, opening a form, or modifying data in a text box.
Events can also be triggered by factors outside of Access, such as system events, or by macros or procedures that are attached to other events.
Your database can get complex if you add many macros or procedures to several event properties of many objects, but in most cases, you can achieve the results that you want by using very little programming. Top of Page. The decision to use macros, VBA, or both depends primarily on how you plan to deploy or distribute the database.
For example, if the database is stored on your computer and you are the sole user, and if you are comfortable using VBA code, you might decide to use VBA to perform most of your programming tasks. However, if you intend to share your database with other people by locating it on a file server, you might want to avoid using VBA for security considerations. You should base your decision to use either macros or VBA code on two concerns: security and the functionality that you want.
Security is an issue because VBA can be used to create code that either compromises the security of your data or can harm files on your computer. When you use a database that was created by someone other than yourself, you should enable VBA code only if you know the database comes from a trustworthy source. When you create a database that will be used by other people, you should try to avoid including programming tools that require the user to specifically grant trusted status to the database.
General techniques for avoiding the need for users to trust your database come later in this section. To help ensure the security of your database, you should try to use macros when you can and use VBA programming only for operations that cannot be performed by using macro actions.
Furthermore, you should try to use only macro actions that don’t require granting trusted status to the database in order to run. Limiting the use of macro actions in this manner lets users to be confident that the database has no programming that could harm the data or other files on their computers. Beginning in the Access release, Access contains many new macro actions that enable you to build more powerful macros than you can build by using earlier versions of Access.
For example, you can now create and use global temporary variables by using macro actions, and you can handle errors more gracefully by using new error-handling macro actions.
In earlier versions of Access, these kinds of features are available only by using VBA. In addition, you can embed a macro directly into the event property of an object or control. An embedded macro becomes a part of the object or control and stays with the object or control if it is moved or copied. Macros provide an easy way to handle many programming tasks, such as opening and closing forms and running reports.
You can quickly and easily tie together the database objects forms, reports, and so on that you have created because there is little syntax that you must remember. The arguments for each action are displayed in the Macro Builder. In addition to the increased security and ease of use that macros provide, you must use macros to perform the following tasks:. Assign an action or set of actions to a key.
This requires creating a macro group named AutoKeys. Carry out an action or a series of actions when a database first opens. This requires creating a macro named AutoExec. For more information about how to build macros, see the section Understand macros. You should use VBA programming instead of macros if you want to do any of the following:. Use built-in functions, or create your own functions Access includes many built-in functions, such as the IPmt function, which calculates an interest payment.
You can use these built-in functions to perform calculations without having to create complicated expressions. By using VBA code, you can also create your own functions either to perform calculations that exceed the capability of an expression or to replace complex expressions.
In addition, you can use the functions that you create in expressions to apply a common operation to more than one object. Create or manipulate objects In most cases, you will find that it is easiest to create and modify an object in that object’s Design view. In some situations, however, you might want to manipulate the definition of an object in code. By using VBA, you can manipulate all the objects in a database, in addition to the database itself. Perform system-level actions You can carry out the RunApp action in a macro to run another program such as Microsoft Excel from within Access, but you can’t use a macro to do much else outside of Access.
Manipulate records one at a time You can use VBA to step through a set of records, one record at a time, and perform an operation on each record. In contrast, macros work with entire sets of records at one time. If you are adding a command button to a form, the Command Button Wizard can help you get started with programming.
The wizard helps you create a command button that performs a specific task. In an Access. In an. In either case, you can then modify or enhance the macro or VBA code to better suit your needs. In the Navigation Pane, right-click the form to which you want to add the command button, and then click Design View.
On the Design tab, click the down arrow to display the Controls gallery, and then ensure that Use Control Wizards is selected. On the Design tab, in the Controls gallery, click Button.
On the first page of the wizard, click each category in the Categories list to see which actions the wizard can program the command button to perform. In the Actions list, select the action that you want, and then click Next. Click either the Text option or the Picture option, depending on whether you want text or a picture to be displayed on the command button.
If you want text to be displayed, you can edit the text in the box next to the Text option. If you want a picture to be displayed, the wizard suggests a picture in the list. If you want to select a different picture, select the Show All Pictures check box to display a list of all the command button pictures that Access provides, or click Browse to select a picture that is stored elsewhere. Enter a meaningful name for the command button.
This is an optional step, and this name is not displayed on the command button. However, it is a good idea to enter a meaningful name so that when you need to refer to the command button later for example, if you are setting the tab order for controls on your form , it will be much easier to differentiate between the command buttons. If the command button closes the form, for example, you might name it cmdClose or CommandClose.
If you want to see what the wizard “programmed” for you, follow these optional steps:. In the On Click property box, click the Build button. Access starts the Macro Builder and displays the macro that the wizard created. You can edit the macro if you want for more information about how to edit a macro, see the section Understand macros. When you are finished, on the Design tab, in the Close group, click Close to close the Macro Builder. If Access prompts you to save the changes and update the property, click Yes to save the changes or No to reject the changes.
Click the new command button to confirm that it works as you expected. A macro is a tool that enables you to automate tasks and add functionality to your forms, reports, and controls. For example, if you add a command button to a form, you associate the button’s OnClick event property to a macro that contains the commands that you want the button to perform each time that it is clicked. It is helpful to think of Access macros as a simplified programming language in which you create code by building a list of actions to perform.
When you build a macro, you select each action from a drop-down list and then fill in the required information for each action.
Macros enable you to add functionality to forms, reports, and controls without writing code in a VBA module. Macros provide a subset of the commands that are available in VBA, and most people find it easier to build a macro than to write VBA code. You create a macro by using the Macro Builder, which is shown in the following illustration.
To display the Macro Builder:. Like macros, VBA lets you add automation and other functionality to your Access application. You can extend VBA by using third-party controls, and you can write your own functions and procedures for your own specific needs. Instructions for doing this are included in the section Convert macros to VBA code. This feature creates a new VBA module that performs the equivalent operations in the macro.
It also opens the Visual Basic Editor so that you can start modifying the procedure. When you are working in the Visual Basic Editor, you can click keywords and press F1 to start Access Developer Help and learn more about each keyword.
You can then explore Access Developer Help and discover new commands to help you perform the programming tasks that you want. You can use Access to automatically convert macros to VBA modules or class modules. You can convert macros that are attached to a form or report, whether they exist as separate objects or as embedded macros.
