procedure TForm1.Button1Click(...);
begin  
  Application.HelpFile := 'DELPHI.HLP';
  Application.Helpcommand(HELP_Key, 0);
end;

Use this code to get the search window of WinHelp

I would do it like this, calls search immediately without searching for a key first :

procedure TForm1.HelpSearch(Sender: TObject);
     var
        HelpMacro:pchar;
     begin
          HelpMacro:='Search()';
          with Application do begin
               Application.HelpContext(1);
               HelpCommand(HELP_COMMAND,longint(HelpMacro));
          end;
     end;

Haven't tried out sassas code, but supose it works too, but I think it first searches for a key and if that key doesn't exists it displays the search dialog.

Thanks for replying at my comment and for letting me know about the recomendation of Microsoft! Do you know also why they recommend it this way? It would be great to know it.

HELP_KEY      Displays the topic in the keyword table that matches the specified keyword, if there is an exact match. If there is more than one match, displays the Index with the topics listed in the Topics Found list box.       Address of a keyword string(If 0 displays the keyboard table).
