The DP4 help system is designed around the concept of field sensitive help. Help text is displayed for each field on a map and for each option on a menu.
The user can toggle the help display on and off by pressing the <Help> key (usually <F10>, <F1> or <Ctrl+J>). To see how help works, run any DP4 utility, and press the <Help> key to get help for the current field. As you move the mouse or cursor around the screen, you will see the help display change to refer to the current field.
To add help to your application, you have two options:
Add help for a field when you set it up using the map editor
Run the help authoring utility to define the help text interactively whilst the application is running
The DP4 help authoring utility is the most productive way to add field sensitive help to your application. You load this utility into memory, and then run your application program. To add a help screen to your program, you simply press the help authoring key (usually <F9>), and you will be prompted for the help text for each field. Unfortunately this utility is not supported with the latest version of DP4 for Windows, but it will be reintroduced shortly.
Your program does not need to position the help popup map. The user interface manager displays help in the clearest part of the screen.
