Adding component help to Delphi #40

Warning: this tip is obsolete. It applies only to Delphi 3 through to Delphi 7 which used the WinHelp system. WinHelp is obsolete and will not run on Windows 10.

Despite what it says in Delphi's documentation, to add component help simply follow these instructions.

1: Add the component help file to the registry

Add the help file's location to


To add

C:\Program Files\Borland\Delphi4\Help\MyHelp.hlp

to the registry insert a value named MyHelp.hlp, with the above path as the value.

2: Enable Delphi to display the component's help keywords in the index


C:\Program Files\Borland\Delphi4\Help\delphi4.cnt

and add the following entry to the end of the file's index section:

:Index My Help Title=MyHelp.hlp

3: Add link support to Delphi's Help system


C:\Program Files\Borland\Delphi4\Help\delphi4.cfg

Add the following line to the end of the file:

:Link MyHelp.hlp

Then add

:Include Delphi4.cfg

to your contents file (MyHelp.cnt).
