HelpFile and EnableHelp properties

rbuser

Delphi 6, RB 10.07.

I have a different help file that I put out with ReportBuilder to our end
users. I have tried setting ppDesigner1.HelpFile := \helpfile.hlp in the Designer's OnShow and OnCreate events, but it
still always shows the RBuilder.hlp file that comes when you install it into
Delphi.

I know this because in the OnHelp event, I put in a debug to show the
aHelpFile parameter, which displayed "C:\Program Files\Borland\Delphi
6\RBuilder\RBuilder.hlp".

Also, I wanted to disable F1 bringing up the help as my file is not context
sensitive. According to the documentation, this is exactly what the
ppDesigner.EnableHelp property is supposed to do. However, it makes no
difference whether this is set to True or False.

Any ideas?

I have worked around it by changing the aHelpFile parameter in the OnHelp
event to my help file.

Thanks,
Jason.

Thanks for reporting this. I tested this with RB 11.03 and found the same
behavoir. The EnableHelp and HelpFile properties are not being honored. This
will be fixed for RB 11.04

The documentation for EnableHelp is not accurate. The intent is to suppress
help. There is no distinction between F1 or Help menu being selected.

A simple work around is to use the OnHelp event as you are doing now. That
event gives you total control. You can either overrride the parameters that
passed to it or set aCallHelp to False and invoke the help with some custom
code.

When the user presses F1, the aKeyPhrase parameter of the OnHelp event will
be specified (when the Help menu is selected the aKeyPhrase is blank). You
can use that information to customized Help processing. Ignore the KeyPhrase
or override it back to blank.

example

aHelpFile := c:\myHelpFile.hlp;

if (aKeyPhrase <> '') then
begin
aKeyPhrase := ''; // force contents to be displayed
// or
// aCallHelp := False; // suppress help
end;
