当 htmlhelp 的参数 uCommand=HH_DISPLAY_TEXT_POPUP时， 如何调用CHM帮助文档
请举例

[lxpbuaa]

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;

宠辱不惊，看庭前花开花落，去留无意；毁誉由人，望天上云卷云舒，聚散任风。
