When running an HTML page from HTML Composer, the web browser displays a Loading, please wait… message, until the page is fully loaded.
You can use the Loading screen property for the BODY object to specify an HTML file of your own to use as a loading screen.
The Get existing html page dialog box opens, as shown in the following image.
Note: Default will use the Information Builders supplied loading screen. Not Set will not use a loading screen.
The file is added to the property, as shown in the following image.
When the page runs, the specified loading screen will display until the page is completely loaded.
