This page contains information on how to create Compiled Help Module (.chm) files for applications that run under Windows. An alternative help system for Tcl developers is to use a [Wikit in local mode] as a help system. ---- I'm no expert but the following items may be helpful to others. Please add your own comments, tools and links. [Tom Krehbiel] * A description of the '''file format''' and be found here [http://www.speakeasy.org/~russotto/chm/chmformat.html] * '''Abee Chm Maker''' is a program for making chm-files. It is '''free''' and can be downloaded form here [http://www.soft411.com/company/AbeeTech/Abee-CHM-Maker-freeware.htm]. It has a simple and comprehensible interface and allow you to make CHM-files(with contents). I tried it on a simple problem and it worked and seemed to be easy to use. * An '''X-Windows viewer''' for .chm files can be downloaded from here [http://xchm.sourceforge.net/] '''Comments''' on .chm by [Pat Thoyts] & [Donal K. Fellows]: "Isn't it HTML+postprocessing?" - Donal K. Fellows "Yes. MS issue a HTML compiler. You can take a web site and turn it into a chm file quite easily. You have to dig around in MSDN to find the package to download though. It used to be on the Platform SDK disk." - Pat Thoyts [PT]: It's called the MS HTML Help 1.4 SDK and you can download it from [http://msdn.microsoft.com/library/default.asp?url=/library/en-us/htmlhelp/html/vsconHH1Start.asp] and view the documentation there.
