Delphi - 如何使用CHM HTML帮助文件与Delphi XE应用程序？

http://edn.embarcadero.com/article/27842 文章介绍如何使用CHM文件。
我做了在那里描述的所有步骤。

添加

  const 
 HH_DISPLAY_TOPIC = $ 0000; 
 HH_DISPLAY_TOC = $ 0001; 
 HH_CLOSE_ALL = $ 0012; 
 
函数HtmlHelp（hwndCaller：HWND; 
 pszFile：PChar; uCommand：UINT; 
 dwData：DWORD）：HWND;标准
 external'HHCTRL.OCX'name'HtmlHelpA'; 
  

和公共函数HH`

 函数TForm1.HH（Command：Word; Data：Integer; 
 var CallHelp：Boolean）：Boolean; 
 begin 
 if（Command = 0）和（Data = 0）then 
 HtmlHelp（Application.Handle，
 PChar（Application.HelpFile），
 HH_DISPLAY_TOC，0 ）; 
 
 CallHelp：= False; 
结束
  

在FormCreate

 code> HelpDir：= ExtractFilePath（Application.EXEName）; 
 Application.HelpFile：= HelpDir +'Sample.chm'; 
 Application.OnHelp：= HH; 
  

在button1上，OnClick事件添加了以下代码：

  HH（0，0，dummy）; 
  

点击button1后，光标会变成沙漏一段时间，这就是全部。 >

我在做什么错？

CHM帮助文件如何从DelphiXE应用程序中使用？

解决方案

您正在从预建日期开始的文章，支持HTML帮助。这些天你们执行以下操作：

• 在你至少有一个你包含 HtmlHelpViewer 使用条款。


• 将 Application.HelpFile 设置为您的帮助文件的路径。

就是这样。您的问题中的代码应该被删除。内置的帮助查看器负责所有这些细节。

Delphi - How to use CHM HTML Help file with Delphi XE application?

http://edn.embarcadero.com/article/27842 article describes how to use CHM file. I did all the steps described there.

Added

const
  HH_DISPLAY_TOPIC        = $0000;
  HH_DISPLAY_TOC          = $0001;
  HH_CLOSE_ALL            = $0012;

function HtmlHelp(hwndCaller: HWND;
  pszFile: PChar; uCommand: UINT;
  dwData: DWORD): HWND; stdcall;
  external 'HHCTRL.OCX' name 'HtmlHelpA';

and public function HH`

function TForm1.HH(Command: Word; Data: Integer;
  var CallHelp: Boolean): Boolean;
begin
  if (Command = 0) and (Data = 0) then
      HtmlHelp(Application.Handle,
        PChar(Application.HelpFile),
        HH_DISPLAY_TOC, 0);

  CallHelp := False;
end;

In FormCreate

  HelpDir:=ExtractFilePath(Application.EXEName);
  Application.HelpFile:=HelpDir+'Sample.chm';
  Application.OnHelp := HH;

On the button1 OnClick event added the following code:

HH(0, 0, dummy);

After clicking on the button1, cursor becomes an hourglass for a while, and that's all.

What I'm doing wrong ?

And how the CHM help file can be used from DelphiXE application?

解决方案

The article you are working from pre-dates built in support for HTML help. These days you do the following:

• Include HtmlHelpViewer in at least one of your uses clauses.
• Set Application.HelpFile to the path of your help file.

And that's it. The code in your question should be removed. The built-in help viewer takes care of all those details.
