The FormHelp component adds the context-sensitive help features to your Delphi/C++ Builder forms without any bulky help files. It traps the context-sensitive help calls and creates its own popup windows from a control's hint. You can choose whether to interpret the hint string as plain text or as kind of rich text allowing you to apply different fonts colors, styles and line breaks. Don't worry about your hints FormHelp uses the secondary part of a control's hint that is separated by a vertical bar "|". Mouse hints still works as well. With FormHelp, neither help context numbers nor extra help files are required to display context sensitive help. FormHelp's popup windows looks and feels like native context help in standard Microsoft's applications. Even if you're using regular help files, the FormHelp will be great addition and vice versa.

The FormHelp can automatically apply the "What's This?" menu item to every control with context-sensitive help in the secondary part of hint, and invokes the context help either after pressing the "Help" button on the title bar ![]() |

If the user then clicks a control in the form, the control receives a WM_HELP message to show the context-sensitive help taken from secondary part of the Hint property.
