Microsoft Access is a component of Microsoft Office, available on all IT Services managed computers at the University. This material has been written to be used.
The first folder, Microsoft Access Class Objects, contains your forms and reports only objects with an associated code module are shown. Clicking one of these objects displays the existing code module.
Below the Project pane is the Properties pane for the project. You can use this window to change the name of the project or of a module.
The VBA project name property should be changed if you use the operating system to copy a database to create a new file, as the file copy operation does not change the VBA project name inside the database The Project pane displays all forms and reports that have code modules. You can use the Modules tab for writing code that is not tied to a particular form or report. Creating a Module You can use the Project window to create a new module. There are several different ways to add a new module; the method shown in Figure involves right-clicking the Modules tab, and then selecting Insert Module from the shortcut menu that appears.
This method is used when you want to concentrate on setting up new modules when you are in the middle of writing and debugging code. Creating a new module or class module from the Project pane. When you create a new module, it is automatically assigned a default name for example Module1. When you click the save button, you will be prompted to give the module a permanent, more meaningful name. Figure shows the new module before it has been saved with an alternative name.
You might also notice that when you save the new module, it contains two special Option keyword lines of text.
After creating a new module, it will be displayed using a default name such as Module1, Module2, Module3, and so on. When you click the save option on the toolbar or close the database, you are prompted to replace the default module name with something more meaningful. Creating a Procedure Modules contain procedures, and the procedures contain program code.

Use the Insert menu to open the Add Procedure dialog box, in which you can add a new Sub subroutine , Function, or Property class modules only. There is also an option to prefix the procedure with the keyword Static, which makes variables hold their value when repeatedly executing the procedure. The Add Procedure dialog box. Creating a new procedure by using the Sub keyword.
The window in the background shows the keyword and the procedure name typed in; the foreground window shows the result after pressing return. Type the word MsgBox, enter a space, and then type a double quotation mark. As you do this, IntelliSense assists you as you type in each part of the syntax for the MsgBox procedure, as shown in Figure.

Executing a Subroutine The subroutine code you created can be executed two ways. The first way is to click the green Continue button on the toolbar menu or press the F5 key you need to have the cursor positioned inside the procedure on any part of the code.
This should then display the message box. The second way is to type the name of the subroutine into the Immediate window, and then press Return, as demonstrated in Figure. The MsgBox function has alternative constants for the second parameter vbYesNo shown in Figure, which control the buttons and graphics displayed in a message box.

This simplifies entering a new constant value. Accessing the shortcut menu to display information about the parameters for the procedure.
Other options on this menu include providing quick information on the function. Executing a Function To run a function, you can press the F5 key, but this will not display the returned value. Notice that when you execute a function you need to add parentheses " " after the function name; a function needs to show that it accepts parameters even when it has no parameters.
Executing a function from the Immediate window. Use the? In this section, you have seen how program code can be written in a module that is not connected to a form or report. These code units are called standard modules, or sometimes general modules or global modules.
Figure illustrates how a standard module is an object that is independent of any form or report. Code written in these procedures can link to other procedures in the same or different modules. The code will normally not be specific to a single form.
The procedures can be a combination of functions and subroutines. Viewing and Searching Code Module code can be viewed either showing the code for a single procedure Procedure view or the entire module Full Module view , using the scrollbars to browse through its contents, as shown in Figure.
Using the buttons in the lower-left corner of the code window, you can display either a single procedure or a scrollable list of all the procedures in the module. Split Window The module code window can also be switched to a Split view. This gives you the ability to compare code in two different procedures, one above the other. Use the Window menu to enable the Split view option.
Drag the splitter bar in the center of the screen up or down to change the proportion of the screen that is used to display each procedure.
Figure illustrates the split window view. Viewing two procedures at the same time in Split view mode. Dragging the splitter bar to the very top of the screen and releasing it will remove the split view. Similarly, by moving the mouse to the top right, just above the vertical scroll bars, the mouse pointer will change shape and you can drag down the splitter bar this can be a little tricky to do and you will find the Window menu easier to use for this.
Creating Modules and Procedures - MS Access
Use the drop-down menu located on the upper-right portion of the window to select any procedure within a module. This applies to each of the windows when using the split view, as well.
Use the drop-down menu to quickly display any function or subroutine in a module. Access Database Design. Quick Start Guide Access Microsoft Access looks different from previous versions, so we created this guide to help you minimize the learning curve.
