问题
I have a number of CHM files, and each of the files is a comressed html for 5 different Html files. I mean, lets say I have 5 different files named Alpha, Beta, Gamma, Delta, Theta. Say, I compress these 5 in a CHM file. Lets call that file CompressedHtm.CHM. I have >500 of these files. Now I want to check if all of these >500 files have all 5 subfiles( i.e. Alpha, Beta, Gamma, Delta, Theta). Is there a way to check that in VC++ 6.0 /MFC without decomiling the CHM files.?
回答1:
With Free Pascal comes a totally standalone(*) command line executable CHMLS that allows to list the contents of a CHM file. It exists for multiple platforms.
You could execute that using pipes and then process the output.
I happen to zip the exes for sb else a few days back, you can get them here http://www.stack.nl/~marcov/chmls.zip
(or download the fpc 2.4.0 windows release if you don't trust me)
(*) I don't know the state on win9x.
The output looks like:

The files starting with # and $ are internal files.
(the tools are utils that come with Free Pascal's CHM library which supports CHM read/write support independant of other tools for Free Pascals documentation and help systems. It's OS independant, and to my best knowledge it works fine on OS X/PowerPC64

HTML Help uses IE for display. So you just need to use a webbrowser to navigate to a URL like mk:@MSITStore:c:\WINDOWS\Help\htmlhelp.chm::/apiref.htm. If the file does not exist, you will get DWebBrowserEvents2::NavigateError with a 404 status code. Note you may get other errors on modern versions of Windows as Microsoft has limited its usage due to security concerns.
