About the Home Page

The Home page contains three distinct sections:

• Customer search field

• Tasks list

• Orders, customers, and products reports

You can search for customers using the Customer Search field. Type a customer name in the Customer Search field and click Go.

The right side of the Home page features two different report formats and a bar chart. Note that in the Top Order report you can link to order details by selecting the Order number. In the Top Customers report you can link to customer details by selecting the customer name.

The Tasks list consists of a series of links that take you to other pages within the application. Links available on the Home Page Tasks list include:

• Enter New Order links to a wizard that walks you through the process of creating a new order. First you select a customer name and then you add items to the order

• Enter New Order links to a form where you can enter new customer information.

• About this Application links to an informational page describing this application.

About the Orders Page

Use the Orders page to search, view, and enter order information. By default, the right side of the page displays current orders. To search for an order, enter the order number in the Search for field and click Go. Click a column heading to sort the information. You view more details about a specific order by clicking the view icon. (See Figure 3-3.)

You can edit a product description by clicking Edit. To add a new product or view a chart displaying products by category, use the Tasks list on the left side of the page.

By default, the right side of the page displays customer information. Click a column heading to sort the information. Click Edit to update customer information. To view all customers or to enter a new customer record, use the Tasks list on the left side of the page.

Viewing Pages in Printer Friendly Mode

Clicking Print in the upper right corner of the page displays the current page in Printer Friendly mode. When in Printer Friendly mode, the HTML DB engine displays all text within HTML from fields as text.

To enable your application to display in Printer Friendly mode, you need to create and then specify a Print Mode Page Template on the Edit Application Attributes page.

About the Developer Toolbar

When you log in to Oracle HTML DB having developer privileges and run an application, a Developer toolbar displays at the bottom of every page. As shown in Figure 3-4, the Developer toolbar offers a quick way to edit the currently running page, create a new page, control, or component, view session state, or turn edit links on or off.

Figure 3-4 Developer Toolbar in Sample Application

The Developer toolbar consists of the following links:

• Edit Application links you to the Application Builder home page. (See "Viewing a Page Definition".)

• Edit Page accesses the Page Definition for the currently running page. (See "Viewing Page Attributes".)

• New links to a wizard that enables you to create a new blank page, a component (report, chart, or form), a page control (region, button, or item), or a shared component (menu, list, or tab).

• Session links you to session state information for the current page. (See "Viewing Session State".)

• Debug runs the current page in debug mode. (See "Accessing Debug Mode".)

• Show edit links toggles between Show edit links and Hide edit links. Clicking Show edit links displays an edit link (resembling four gray dots) to the right of most page components or controls. By clicking an edit link you can edit the selected component or control.

Editing a Demonstration Application

There are two common ways to edit a demonstration application:

• From Demonstration Applications page, click Edit next to the desired application

• If you are running an application, click Edit Application on the Developer toolbar

As shown in Figure 3-5, the Available Applications list displays at the top of the Application Builder home page. Note that the Available Applications list displays the current application name.

The current application ID, last update date, authentication scheme, alias, owner, and selected template display directly beneath the list. You can run an existing application, create a new application, edit application attributes, or export information by clicking the following icons:
