Help in the program

[mrkaban]

Hello dear friends! Thank you very much! You regularly help me!

Now I want to make the help system for my program. Found in the folder with Lazarus in the "examples" example "htmlhelp_ipro". I liked him!

I decided to try to remake for myself. I copied and connected the forms htmlhelp2viewer in uses. Created the main form event in his program "OnCreate", and added:

Code: Pascal  [Select][+][-]

1. HtmlHelp2Viewer.RegisterHelpViewer;

I try to call the opening like this:

Code: Pascal  [Select][+][-]

1. ShowHelpOrErrorForKeyword('','help/index.html');

Also added a non-visual component "HTMLHelpDatabase". Here are its properties:

Code: Pascal  [Select][+][-]

1.   object HTMLHelpDatabase1: THTMLHelpDatabase
2.     BaseURL = 'file://help/'
3.     AutoRegister = True
4.     KeywordPrefix = 'help/'
5.     left = 136
6.     top = 304
7.   end

Tell me please, I can not figure it out myself. When you try to open this help, the program writes "Access violation".

Thankful in advance for any help!

And immediately I apologize for my English. Also ready to show the source code.
