Lesson 7.2. Modifying a Form
Figure 7-3. A form in Design view.
After you create a form, you may decide to modify it to add additional features or make it easier to use. For example, you might want to add or delete a field or change the location of a field on the form. You modify a form in Design view, which you can get to in two different ways:
From the database window: Click the Forms icon to list the forms in the database. Click on the form you want to modify and click the Design button.
From a form window: Click the View button on the toolbar or select View Design View from the menu.
This lesson will introduce you to form Design view.
From the Database window, click the Forms icon in the Objects bar if it isn't already selected, then select the frmCustomers form and click the Design button.
The frmCustomers form appears in Design view, as shown in Figure 7-3.
Don't let Design view scare you. It looks more complicated than it really is. In some ways, form Design view is similar to many Paint programs. Think of the form as your canvas and the Toolbox and Field List as the paintbrushes you use to add fields, text boxes, and buttons to the form.
Any graphic object that appears on forms and reports is called a control. A text box used to enter and display information, a text label, and a button you click to print a report would all be examples of controls. You add controls to a form by clicking the control you want to use and then by clicking and dragging it on the form to draw the control. Table 7-2 shows and describes Toolbox buttons and controls.
Table 7-2. Toolbox Buttons and Controls
Click this button and then click the control you want to select. To select multiple controls, click this button and hold down the Shift key as you click each control, or drag a rectangle around all controls you want to select.
Click to use Control Wizards when you add controls to your form.
