How to open HTMLHelp (.chm) file from Borland C++ Application

Question

We have a legacy application developed in Borland C++ Builder. Now we have updated the help file to HtmlHelp (.chm) file, we want to click on the Help button in the legacy c++ application to open the .chm file. It seems that I cannot find a good way to do this? Can anyone help?

Answer 1

My application uses HTML Help but in a newer version of C++ Builder.

Here is a code snipit of how we include it in the main form.

//helpviewer
#include "HTMLHelpViewer.hpp"
#pragma link "HTMLHelpViewer"

In the formactivate

Application->HelpFile = "some drive letter:\\some directory\\somehelpfile.chm";

To display the help

Application->HelpCommand(HELP_CONTENTS,0);

Hope this is of some value
