1. Introduction to Microsoft Access
Part 4 – Forms
The purpose of any form, whether paper based or electronic, is to capture
information. Because many people get confused when filling out forms, it is
important that their design is as simple as possible.
1. Creating AutoForms
Start by opening the Northwind Database and delete all the existing forms. Now
open one of the tables in Datasheet View and enter data into the table. Doing this is a
relatively simple process. What then, is the point of creating forms for Access
databases?
• Forms allow you to focus on one record at a time with all the data pleasantly
laid out on the screen.
• You can edit the form at any time by switching to Design View and you don't
have to worry about recycling 10,000 copies of the old form, as you would if
the form was a PBF (Paper Based Form).
• You can build several forms for different groups of users to reflect their
different needs.
• You can use the form to view the contents of tables or the results of queries.
• One form can be used to enter data into several tables. Forms automatically
use the relationships built into your database.
1. Click on the Forms tab of your Database Window.
2. Click New and choose between the three types of AutoForm.

2. The three types of AutoForm are:
Columnar Produces a simple one-record-per-form view
Tabular Shows multiple records on a form
Datasheet Produces a form that looks almost exactly like a table in
Datasheet View.
3. Choose the Columnar AutoForm and select the Customers Table. You should
end up with something like this:
4. Give the form a title and save it.
Your Task
Try creating a Tabular AutoForm and a Datasheet AutoForm, both based on the
Customers Table. Compare the layout of the three forms.
1. Which layout is the simplest?
2. What is the point of creating a Datasheet form, when you could just open a table
in Datasheet View to enter data?
3. What is the advantage of the Tabular form?
4. Was there any problem with the layout of the Tabular AutoForm?

3. 2. Creating a Form with the Form Wizard
The Form Wizard is much more versatile than the AutoForms and it allows you to
select fields from several tables and/or queries.
1. Go to the Forms tab of your Database Window. Click New and then Double
Click the Form Wizard.
2. Select the fields you want to use in your form from any table or query. If you use
more than one table or query, the Wizard will ask you how you want the form to be
arranged.
3. You will be asked what layout you want. Choose between Columnar, Tabular,
Datasheet and Justified (Columnar produces the simplest layout).
4. You can then choose the
colour and background styles.
Choose the standard option to
begin with because many of
these colour options slow down
the performance of your form.
5. Name your form and then click Finish.
Your Task
1. Delete the three forms that were created with AutoForm.
2. Using the Form Wizard, create a form what uses fields from more than one table.
Think carefully about the sort of forms that Northwind will need and create a form
that will suit their purposes.
3. Test the form by entering a few records. Is data entry intuitive and problem-free?
4. What do each of these buttons at the bottom of the form do?
5. Evaluate your form. Did the Form Wizard produce a perfect form? Are there any
layout problems? How could the layout be improved?

4. 3. Taking the Form into Design View
1. With your form open, click the Design View button.
If you have previously worked with reports, this screen will be familiar to you
because it is very similar to the Reports Design View. Objects can be moved, edited,
re-sized and aligned in exactly the same way.
2. Click the appropriate button in the Toolbox to enter lines and boxes. Resize or
move them with the Pointer tool. When an object is selected, the large selection
handle moves the object and the other selection handles resize the object.
Large selection
handle moves
an object
line
Small selection
handles resize
an object
Square/rectangle
3. You can change the colour of any object. You can alter the Line/Border Width
and you can add special effects. The Format Painter is a useful way of applying the
same visual style to all your labels and/or data boxes. OLE Objects can be added to
forms, just as they can be added to reports.
4. You have a Header and Footer, in which you can place objects that will appear at
the top or bottom of your form.
5. Just as in the Report Design View, you can double-click on any Object (e.g. a
data box, a label or a form section) to bring up a Properties dialog box. Click the
Form Properties button to make changes that affect the behaviour of the whole form.
Your Task
Improve the layout of your
form, change the colour
scheme, add a header and
preview the results.

5. 4. Change the Tab Order
When people enter data into a form, they usually use the Tab key to move between
fields. If you move the data boxes around in Design View you will notice, when you
preview the Form in Form View that Access has remembered the old tab order. This
will be confusing for people using the form. The solution is to return to Design View
and update the Tab Order.
1. Select Tab Order from the View Menu. The Tab Order dialog box appears:
2. Click on the grey button next to a field and drag it to the desired position.
3. When you're satisfied, click OK and test the new tab order in Form View.
Your Task
1. Change the order of the
data boxes on your form.
Then update the Tab
Order.
2. Add the date and time to
the Form Footer (the
process for doing this is the
same as for reports).
3. Remove the Scroll Bars
from your form. To achieve
this, you will need to edit
the Form Properties.
4. Preview the results of
these changes in Form
View.

6. 5. Subforms
A Subform is a "form within a form". The form in the example below is based on
two tables called Categories and Products. The main form is based on the
Categories table and the Products table is the subform. When the Beverages
Category is selected, the Products subform displays only products in that category.
You will use the Northwind Database to create a form based on the Orders table
that uses the Products table as a subform.
The purpose of creating this subform is:
• Whilst employees are taking orders, they can see the details of the items being
ordered.
• The employee can change data in the Products table without leaving the
Orders form.
1. Start the Form Wizard.
2. Add fields from the Orders table and the Products table.
3. You are then asked how you want to view the data. If you view by the Orders
table, you ensure that Orders is the form and Products is the subform.
4. Choose a Tabular or a Datasheet view.
5. Complete the wizard and your form is created. Notice how the wizard has
helpfully created some combo (drop-down) boxes to aid data entry in certain fields.
For Discussion
1. Why is it important to make sure that relationships are set up properly before
creating a subform?
2. How do the combo boxes contribute to data validation?

7. 6. Adding a Subform to an Existing Form
1. Create a second form based on the Orders table. We want a simple form as
quickly as possible, so use the Columnar AutoReport to make the form.
2. Switch to Design View and enlarge the Detail Section so that there is room for the
subform:
3. Ensure that the Control Wizards Control
are turned on and click the SubForm/ Wizards on
Subreport button on the Toolbox:
Subform/
Subreport
4. Add the subform to your form and a wizard will start. Simply tell the wizard that
you want to base the subform on the Products table and it will create the subform for
you. Ignore the page about linked fields.
5. Re-size the subform as necessary and preview the results in Form View. Then
return to Design View and open the subform's Properties. Customise your subform
by adding a Border Colour and a Special Effect.
Your Task
1. Turn the Control Wizards off and then try to create a subform. What do you
notice?
2. Your boss has asked you to make some changes to the form that prevent users
from closing, moving or re-sizing the form while they're working on it. Open the
Form Properties and make some changes that will achieve this.

8. 7. Combo Boxes and List Boxes
Combo boxes are drop-down lists that the Form Wizard, will often create for you.
These boxes help with Data Validation by forcing the user to choose an answer from
a list. If an operator has to choose an option from a list, there is no danger that s/he
will type in something that is invalid. You can also set a Default Value.
1. Open the Music Database that you created in Introduction to Access Part One.
2. Create a form using the Form Wizard based on the Albums table. It is important
to use Form Wizard and not the AutoForms because only Form Wizard
automatically generates combo boxes.
3. Test the form. You should notice that the combo box is listing the ID numbers of
the artists and music categories and not the names. This form will clearly be difficult
to fill in.
4. Take the form into Design View.
Open the Properties for the first
combo box. Make the Column
Count 2:
5. Preview the results. The form should now be listing both the ArtistID and the
ArtistName. We could do without the ID altogether though, so take the form back
into Design View and change Column Widths to 0 (zero). Preview the form again
and it should only list the names of the artists. This is now a much easier form to
work with.
Your Task
1. Go back to Design View and delete the
combo box for the Category field.
2. From the Toolbox create a List Box (make
sure the Control Wizards are on).
3. Base the List Box on the Category field of
the Category table. Make sure you tell the
wizard to store the value selected in the
Categories field of the Albums table.
4. Align the fields in the form and make the
Vertical Spacing equal.
5. Add visual effects to the List Box by editing
the Properties.
6. Test your form by adding details of some
albums. Do you need to change the Tab Order?
7. Set a Default Value for your list box.
