uses ShellAPI;

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
ShellExecute(0, 'open', PChar(Application.HelpFile), nil, nil, SW_SHOW);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
Application.HelpFile := 'g:\NetShow.chm';
end;

或者：
implementation

{$R *.dfm}

function HtmlHelpA(hwndCaller: THandle; pazFile: String;
uCommand, dwData: DWord): DWord; stdcall external 'hhctrl.ocx';


procedure TForm1.Button1Click(Sender: TObject);
begin
HtmlHelpA(Handle, Application.HelpFile, 0, 0);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
Application.HelpFile := 'g:\NetShow.chm';
end;
