如何在Delphi 7程序中调用chm文件的帮助？

Application.HelpFile := 'd:help.chm';
Application.HelpCommand(HELP_CONTEXT,10);

结果是

Why can’t I get Help from this program?

The Help for this program was created in Windows Help format,which
depends on a feature that isn’t included in this version of Windows.
However,you can download a program that will allow you to view Help
created in the Windows Help format.

For more information,go to the Microsoft Help and Support website.

解决方法

问题是,默认情况下,Delphi 7假定帮助文件使用Vista未附带的旧WinHelp格式.即使您的帮助文件具有.chm扩展名,Delphi也会尝试使用WinHelp命令显示它.由于WinHelp不存在,您将收到您报告的错误消息.

有多种方法可以让帮助系统显示HTML帮助.例如,一种常见的技术是为Application对象实现OnHelp处理程序,并将帮助路由到HtmlHelp API的调用.我在recent answer中给出了一个非常简单的例子.
