How can I change the default BED help file (.chm) reader in BED?
« on: February 10, 2024, 01:35:39 PM »
I'm having problems when trying to open the BCXHelp.chm file? The default windows reader for some reason will not show the pages properly, and I can only see the left-hand tabs. When I click on the tab contents, nothing shows up in the main window. I have previously checked the properties of the help file and clicked "unblocked" and this has cured the problem. However, on the latest downloaded version the files has not been blocked by windows, so I can't unblock it. I have also checked the permissions for this file and checked my antivirus in case it has blocked the file. Still no joy. I have found an open source chm reader (https://www.sumatrapdfreader.org/free-pdf-reader) and it opens the file properly. Windows has associated the Sumatra pdf reader as the default .chm reader. But on trying to open the BCXHelp.chm file from within BED the default reader is invoked which I don't want. Is there any way I can change BED to enable me to select Sumatra pdf reader as the chm file reader? Thanks.

PS. Project on Github https://github.com/sumatrapdfreader/sumatrapdf/tree/master

Not easily.  It would require a code change, a full recompile of BED, and testing.

I've used Sumatra in the past and it is a fine bit of software but coupling it to BED to launch
BcxHelp.chm while retaining BED's F1 lookup capability would require some experimentation.

If I were you, I'd be more interested in discovering why overwriting an old version of BCXHelp.chm
inside \Bed\Help\ is not working on your computer.  Seems fishy to me ...

I may have sorted it now. The Comodo Antivirus was putting hh.dat into auto containment as it recognised it as suspicious for some reason. hh.exe is used to open any .chm files.
