KeyFndHH is a dll that works in conjunction with HTML Help to locate CHM and ITS files. Once KeyFndHH is installed, you can link from a compiled or non-compiled HTML file to a file within a CHM or ITS file, provided the file's location meets one of the following criterion:
KeyFndHH is not limited to files displayed by an HTML Help window -- you can also display an HTML file within the Internet Explorer browser, and link to a CHM file. (Note that because Netscape does not support pluggable protocols, you cannot currently use Netscape to access any files within a CHM or ITS file).
Nothing. You are free to use and redistribute KeyFndHH as you see fit.
KeyFndHH works by registering itself as a file finder for .chm and .its files. HTML Help also registers itself as a file finder for .chm files, but as of the 1.2 release, it cannot actually find any CHM files. If HTML Help is installed after KeyFndHH, it will replace the registry entry for KeyFndHH with its own. This means that you must always reinstall KeyFndHH any time that you install HTML Help.
You must have adminstrative priveleges on NT before you can install KeyFndHH. This is the same requirement that exists for HHUPD (HTML Help Update), so if you can install HTML Help, then you can install KeyFndHH.
The KeyFndHH dll does not contain any user interaction, so it will work in all languages. However, the setup program, kfsetup.exe does contain strings used for message boxes. If you have a program that modifies strings resources, you can use that to change the strings in kfsetup.exe. Otherwise, you must install KeyFndHH.dll yourself. When installing it yourself, you should use the following guidelines:
