FormHelp component + Source Code (Site license)

I recently tried out the FormHelp component for Delphi/BCB forms, and I was impressed with how easily it adds context-sensitive help features without requiring bulky help files. With FormHelp, you can trap the context-sensitive help calls and create your own popup windows from a control's hint. Plus, the component gives you the option to interpret the hint string as plain text or rich text so you can apply different fonts, colors, styles, and line breaks.

One thing I appreciated about FormHelp was how it uses the secondary part of a control's hint that's separated by a vertical bar '|' so you don't have to worry about your hints. And, mouse hints still work as well. The best part is that neither help context numbers nor extra help files are required to display context-sensitive help. You can even customize the look and feel of the popup windows to match the native context help in standard Windows applications.

FormHelp also includes a WYSIWYG help designer, which makes it even easier to develop context-sensitive help. To use it, you simply drop FormHelp onto your form and then try to edit the secondary part of the Hint property of any visible control, such as TButton, TCheckBox, or TGroupBox. Additionally, you may have an additional button on your form's title bar for extra convenience.

Overall, I would highly recommend the FormHelp component for anyone looking to add context-sensitive help features to their Delphi/BCB forms without the hassle of bulky help files or extra help context numbers. Its user-friendly interface and customizable options make it a top choice for developers.
