Hh.exe parameter (full)

Note: hh.exe is a small program that opens the CHM File under a command. However, on a certain day, I found a netizen's --hh.exe hidden parameter cloud ...... Hey hey ...... Just as we found Copy 1 + 2> 3 in the past, hh.exe is common.

Enter hh/? In cmd /? Why is there no response on the screen? Then, enter HH ntcmds.chm--in the command line help document and you will not find hh.exe. What tool does it use? Why does it exist without its explanation?

So I went to Microsoft to find it. It turned out to be the HTML Help Workshop command line tool. So what is HTML Help Workshop? hey, let's tell you-all the compiled help documents (CHM) in the system come from it.

Take a look at its parameters:

Hh.exe	-800	Set Help Viewer to 800*600
	-Title	Display CHM in window 800*600
	-Register	Register hh.exe and set it as the shell of the default CHM document
	-Decompile	Decompiling CHM files means breaking CHM apart. It is useful for destructive attackers and translators.
	-Mapid	If you remember the HTM and HTML IDs in CHM, use it to locate the HTM and HTML files.
	-Safe	Force hh.exe to enable CHM in safe mode. Security Mode? That is, all the shortcut keys are invalid.

Although it is a shortcut key, it is not very practical. For a CHM document, the best thing is the bookmark function, especially the CHM with a lot of content.

Microsft spared no effort to launch CHM, but was threatened by PDF from Adobe. It is not easy to edit (unless decompiled -_-!). But the disadvantages are also obvious, the interface is unfriendly, the printing function is not strong, the security performance is not high (easy to decompile) and so on.
