Working with forms
524 InfoMaker
What happens
You are now running the form. Command buttons and picture buttons you have
placed in the form are now active. For information about adding controls to a
form, see Chapter 20, “Enhancing Forms.”
Exactly what you can do when you run the form depends on the form style. It
is the form style that determines the menu items that display in the menu bar
and the buttons that display in the PainterBar when you run a form.
Typically when you run a form, InfoMaker retrieves the data from the database
and displays it to you; then you can scroll through existing data and add,
modify, and delete rows in the database.
You (and your users) can add or modify data in a form in multiple input
languages. If you use multiple input languages, you can display a Language bar
on your desktop to change the current input language. In a form, the input
language in effect the first time a column gets focus becomes the default input
language for that column. If you subsequently change the input language when
that column has focus, the new input language becomes the default for that
column. This behavior does not apply to columns that have the RightToLeft
property set.
When you change data using a form
If you change data and you do not click the Update button before closing the
form, InfoMaker prompts you to save data in the database before closing the
form.
For complete information about what you can do when running forms that use
InfoMaker’s built-in form styles, see “Actions in forms” on page 527.
If you need information about running forms using a style developed by a
PowerBuilder user at your site, see the developer.
Limiting the retrieved data
After you run a form, you can specify criteria that limit the rows of data and
cause a re-retrieval of rows.
❖ To specify criteria to limit the data:
1 Do one of the following:
• Click the Criteria button in the toolbar.
• Select Rows>Specify Criteria from the menu bar.
