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. 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. 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. You can also convert global macros that are not attached to a specific form or report. If your Web database contains VBA code, you must first open the Web database by using Access before you can run the code.
To perform programming tasks in a Web database, use Access macros instead. This process converts to VBA any macros that are referred to by or embedded in a form or report or any of its controls and adds the VBA code to the form or report's class module.
The class module becomes part of the form or report and moves with the form or report if it is moved or copied. In the Navigation Pane, right-click the form or report, and then click Design view. In the Convert form macros or Convert report macros dialog box, select whether you want Access to add error handling code to the functions it generates. Also, if you have any comments in your macros, select whether you want to have them included as comments in the functions. Click Convert to continue.
If no class module exists for the form or report, Access creates one and adds a procedure to the module for each macro that was associated with the form or report. Access also changes the event properties of the form or report so that they run the new VBA procedures instead of the macros. While the form or report is still open in Design view, if the property sheet is not already displayed, press F4 to display it. On the Event tab of the property sheet, click in any property box that displays [Event Procedure] , and then click the build button.
To view the event properties for a specific control, click the control to select it. To view the event properties for the entire form or report, select Form or Report from the drop-down list at the top of the property sheet. Access opens the Visual Basic Editor and displays the event procedure in its class module. You can scroll up or down to view any other procedures that are in the same class module. In the Navigation Pane, right-click the macro that you want to convert, and then click Design View.
In the Convert Macro dialog box, select the options that you want, and then click Convert. Under Modules , double-click the module Converted Macro- macro name. Unlike a class module, a standard module is not part of a form or report.
You will most likely want to associate the function with an event property on a form, report, or control so that the code runs exactly when and where you want. To do this, either you can copy the VBA code into a class module and then associate it with an event property, or you can make a special call from the event property to the standard module by using the following procedure. In the Visual Basic Editor, make a note of the function name.
For example, if you converted a macro named MyMacro, the function name will be MyMacro. In the Navigation Pane, right-click the form or report with which you want to associate the function, and then click Design View. Microsoft Office Access is a wonderful database application introduced and maintained by Microsoft. This software is the answer for anyone who seeks to have a powerful database for their desktop applications.
Like Oracle is associated with Server database, Access is always the most preferred desktop database by anyone. But do not underestimate the power of this software to be only associated with desktop applications. This database can be very well used for any moderate to high-end application too.
The most important feature of this database is its very powerful database engine. It is very effective in its searches and since this database is designed to be compatible with all other Microsoft products, integration of this database with any other Microsoft application is quite easy, effective, and a smooth flow process.
The well designed and effective GUI graphical user interface is another mentionable feature of this database. The GUI is very friendly and encouraging even for a beginner to understand the design and features of this database. The only factor which is bothering is the cost factor. It is relatively expensive, especially for a small time developer who wishes to integrate their application with this powerful database. Access is the database application in the Microsoft Office suite.
Get Access help designing an Access database and sorting and filtering records, among other tasks. Jun 17, Microsoft Access is a database creation and management program.
