This is a companion document to Microsoft Access Techniques. OLE Automation commonly refers to access to Microsoft Office applications. Records 1 - 19 Microsoft and Access are registered trademarks of Microsoft Cor- poration .. viii. Access VBA Programming for the Absolute Beginner, Second Edition Take an ATM (automated teller machine) menu, for example. After. Automation of an Access database can occur at three different levels: That is, they are controlled by blocks of Visual Basic for Applications (VBA) code . Depending on which command you click, Microsoft Access displays.

Instead of running the export wizard every time, take the time to create a macro for the most common PDF export tasks. First, create a macro using Visual Basic for Applications: Once you have enabled the Developer tab, select the tab and press the Macros button. In the Macros in list, click the template or document in which you want to store the macro. In the Macro name box, type a name for the macro. Click Create to open the Visual Basic Editor. Note: Please note that Microsoft Word ships with some built in macros and you should avoid using their names.

This is achieved through what is referred to as Early or Late Binding. These application objects create the OLE link to the application when they are first created. Commands to the different applications must be done explicitly through these application objects in order to work correctly.

As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that for instance runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email. The language provides a user interface in the form of UserForms, which can host ActiveX controls for added functionality.

Using VBA, most of the security features lie in the hands of the user, not the author. The VBA host application options are accessible to the user. The user who runs any document containing VBA macros can preset the software with user preferences. End-users can protect themselves from attack by disabling macros from running in an application or by granting permission for a document to run VBA code only if they are sure the source of the document can be trusted. It became an instant success among developers to create corporate solutions using Excel.

Access VBA Programming

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. 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. In contrast, macros work with entire sets of records at one time. Top of Page Use the Command Button Wizard to perform common programming tasks 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. In the form design grid, click where you want the command button to be placed. The Command Button Wizard starts. 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.

Click Next. 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. Click Finish. Access places the command button on the form. If you want to see what the wizard "programmed" for you, follow these optional steps: If the property sheet is not already displayed, press F4 to display it. Click the Event tab in the property sheet. 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. Top of Page Understand macros 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. 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 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.

Convert macros that are attached to a form or report 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.
