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. 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.
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. Yes No. Thank you!

Too technical. Not enough information. Macros are mini computer programming constructs. They allow you to set up commands and processes in your forms, like, searching, moving to another record, or running a formula. Microsoft Access and Excel are very similar yet very different. Here, are some important difference points between both of them-.
Note: We assume you have the latest Microsoft Access installed which comes bundled with Microsoft Office package. You will find the list of installed programs.
Before we create a Database, lets quickly understand the holistic picture of what Database is, with particular reference to MS Access. Result : The below window will appear. All the Database templates are displayed below. Step 2 We can select any template by clicking on it.
Click on Contact Template for further reverence. Step 6 Optionally, you can click on any of the objects from left navigation pane and open that object for further references and work. For, E. The first step in this Microsoft Access tutorial to store data in the database is creating a Table where data will reside.
Post creation of the table, we can keep inserting the rows in the table. Step 1 First Click Create tab. Then from Tables group, click Table.
Step 2 Table Dialog box appears.
