Solution to the failure to open e-books (CHM)

1. "This page cannot be displayed" is displayed in the content area on the right"

I downloaded several good CHM e-books yesterday, but I found that:
The directory tree on the left is displayed normally, but "this page cannot be displayed" is displayed in the content area on the right"

I searched the internet and found the cause of the problem:
After Microsoft Update 896358 is installed on WINXP and win2003 systems, some CHM cannot be enabled.

Ms's own explanation is:
Http://support.microsoft.com/kb/892675

Basically, I think this update is a bit superfluous. After all, it is better than the virus of executable files,
The CHM carrying viruses is minimal. Solution kb also says, I personally like method 2,
Import the registry. However, it seems that "maxallowedzone" = DWORD: 00000001 is not too work,
I want to increase it to 3 and add another line here.

Regedit4
[HKEY_LOCAL_MACHINE/software/Microsoft/htmlhelp]

[HKEY_LOCAL_MACHINE/software/Microsoft/htmlhelp/1.x/ hhrestrictions]
"Maxallowedzone" = DWORD: 00000003

[HKEY_LOCAL_MACHINE/software/Microsoft/htmlhelp/1.x/ itssrestrictions]
"Maxallowedzone" = DWORD: 00000003

Paste the preceding text into a text editor (such as NotePad. Then, use the. reg file extension to save the file and import it to the Registry. (back up the Registry first ).

 

II,

In win2003sp1, the Registry is imported according to the above operations, but the newly downloaded CHM File still displays "this page cannot be displayed "!
Solution ):
1. Right-click the CHM File and choose "open mode"-"Microsoft HTML Help executable" from the shortcut menu ";
2. If a prompt window appears, it means that the publisher of the CHM File is unknown and whether to open it. Be sure to remove the check box "prompt this window every time! Otherwise, "This page cannot be displayed.
3. After opening, the content area will be displayed as normal! Double-click the CHM File to display it normally!

III,

1. symptom
"You cannot open the file MK: @ *. chm"
2. Cause
(1.exe install other software to build .chmand hh.exe lost Association
(2) The region settings are incorrect. (It may also be because a software installation automatically modifies the regional language)
3. Solution
(1) the simplest task is to execute C:/winnt/system32/dllcache/hh.exe.
(2) Register C:/winnt/system32/hhctrl. ocx (regsvr32 C:/winnt/system32/hhctrl. ocx)
(3) try to adjust Control Panel-region settings-language

Iv. Solutions for Windows XP system failure to open CHM files

1. If your operating system is in English, you only need to change the language settings in the control panel to Chinese.
Start-control panel-data, time, language and regional options-Regional and language options. in the regional options label, change the language to Chinese (PRC), so that the English version of the system can read Chinese e-books.
2 If the Chinese version is used, refer to the following method:

1. Run regsvr32 itss. dll on the command line.
2. Run regsvr32 hhctrl. ocx on the command line.
3. Right-click to associate the "open mode" of the CHM File to/Windows/hh.exe
If the problem persists, you may try to copy a later version to another system because your XP has not been upgraded to SP2 and the hhctrl. ocx version is too low.
