In this tutorial you will learn about databases in general and about the Access database For this reason, when you view a table in an Access database, you. In this extra chapter, you learn about databases and the way databases work. Microsoft Access to create a new database and to create the forms, queries, and . 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.
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. You can type a subroutine name into the Immediate window, and then press the Return key to execute it.
The second type of procedure in VBA is called a function. The key difference between a function and a subroutine is that functions are always expected to return a value. The MsgBox statement can be written in two different ways: the first is to write it when you want to display a message with an OK button where it looks like a Sub ; the second way is illustrated in Figure, where you want to gather input from a user it behaves like a function.
The MsgBox function prompts the user with two buttons Yes and No , and then tests to see which button the user pressed. After you have typed in a call to either a built-in procedure or your own procedure, you can right-click the shortcut menu to display information on the parameters for the procedure or get assistance with selecting constant values. 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.
To change a constant value in the MsgBox routine, hover the mouse over the existing value, right-click to display the shortcut menu, and then select List Constants. 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.

Improving the quality of our work References for Appendix Introduction: Who is this document for? Preface The booklet aims to help you learn how to design and build applications using Microsoft Access. This document is written to be read and understood as you are working on your own design and build experiments.
This Access database design and implementation document is a higher-level self-instruction booklet; it is assumed that you are already a fairly competent Access user. If you need to learn how to use Microsoft Access, please see section 1.
Four basic levels of skill can be recognised in database use. These are: Straightforward data input, amendment and querying, such as might be undertaken by a clerical or professional worker who is expected to capture and use data as a small part of their every day work; Basic database implementation skills, including design of simple databases and implementation of the design as a series of tables, queries and reports; such skills might be anticipated in a professional worker in an office environment who has some responsibility for the basic information systems IS needed in that office, but whose primary job responsibility is not IS- oriented; Real database design and implementation competence.
You would expect this in an information systems professional.
But this same higher level of competence may also be found in certain business-oriented individuals who take a real pride in using computers to their full potential. Such individuals are sometimes referred to as power users. The work of such an individual includes serving the needs of other clerical and professional office workers by undertaking detailed analysis, design and implementation work and creating systems usable by other office workers and business professionals.
Corresponds to Level 4 above Note that material which only applies to Level 3 or above is shown in grey-background Arial Narrow, like this paragraph.
Then read the rest of the document, but ignoring this kind of text. Later, reread the document including text like this. About Learning Access You should work your way through the following stages: 1. This Designing and Building Access Database Systems guide cannot help you to learn these basic skills, which you are assumed already to have — but may have to acquire, revise and practise them, at the same time as you are reading this booklet.
Working through this document, and using the facilities of each Office programme just a little bit more each time, should get you to about this stage. This is the person who has mastered spreadsheets and uses them frequently, and who knows when to use a database.Corresponds to Level 4 above Note that material which only applies to Level 3 or above is shown in grey-background Arial Narrow, like this paragraph.
