[求助]：VL中怎么使用chm帮助？

didini

就像CAD一样，如何调用？
怎么样调用每一个命令的帮助？

不明白这位先生的意思，请明白点说，好吗？

就是针对每个命令，都有帮助，在CAD中直接输入某个命令后，会直接找到，这个命令的帮助，但是我说的是自己编得！

(help "AAA.chm"  "BBB.html")
AAA为你编译好的帮助文件
BBB为帮助文件中的一个超文本文件名

Invokes the Help facility

(help [helpfile [topic [command]]])

Arguments

helpfile

A string naming the Help file. The file extension is not required with the helpfile argument. If a file extension is provided, AutoCAD looks only for a file with the exact name specified.

If no file extension is provided, AutoCAD looks for helpfile with an extension of .chm. If no file of that name is found, AutoCAD looks for a file with an extension of .hlp.

topic

A string identifying a Help topic ID. If you are calling a topic within a CHM file, provide the file name without the extension; AutoCAD adds an .htm extension.

command

A string that specifies the initial state of the Help window. The command argument is a string used by the uCommand (in HTML Help) or the fuCommand (in WinHelp) argument of the HtmlHelp() and WinHelp() functions as defined in the Microsoft Windows SDK.

For HTML Help files, the command parameter can be HH_ALINK_LOOKUP or HH_DISPLAY_TOPIC. For Windows Help files, the command parameter can be HELP_CONTENTS, HELP_HELPONHELP, or HELP_PARTIALKEY.

Return Values

The helpfile string, if successful; otherwise nil. If you use help without any arguments, it returns an empty string ("") if successful, and nil if it fails.

The only error condition that the help function returns to the application is the existence of the file specified by helpfile. All other error conditions are reported to the user through a dialog box.

Examples

The following code calls help to display the information on MYCOMMAND in the Help file achelp.chm:

(help "achelp.chm" "mycommand")
