See registry.c for the Windows part and
MacPreferences.m for the Mac part.
M. Beeson
1.18.00 started
3.24.00 modified
4.5.00 added PrintGraphsInColor, get_color_printing, set_color_printing.
4.6.00 added German to default_installdata
6.15.00 last modified
6.24.00 added graph paper initialization in DefaultGraphColors
and GetFactoryGraphColors
7.15.00 added wcolors.h and used the identifiers there instead of RGB
7.16.00 added call to FactoryGraphPaper
7.22.00 added graphpaper in RegSaveValues
7.27.01 tinkered with messages in readinit
8.17.04 removed DeleteTextbook
8.23.04 changed RecognixSystemKey to HelpWithMathSystemKey;
created reg.h
8.24.04 changed the way language support works so that under the key "Languages"
there is a number stored for "French" and for "German"; the number is 1 if
that language is supported and 0 if not. This will have to be changed explicitly
if more languages are supported. [in 2007 changed this, see init_languages]
8.31.04 changed KEY_READ | KEY_WRITE to KEY_ALL_ACCESS.
wrote copy_whichdisk and called it in RegGetMathXpertKey
9.9.04 removed copy_whichdisk and modified RegSaveValues not to save
whichdisk
9.12.04 if 0'd out obsolete code that enable MathXpert to run without being installed,
by setting its own registry entries.
Set nlanguages = 3 in RegGetValues
11.9.04 undid the change of 8.31, and made many other changes designed to support
running on a network server, or even locally when logged in under a different
username than the one who installed MathXpert. So we must not assume that
registry data exists under HKEY_CURRENT_USER or that the user has write permission
on the registry.
11.10.04 added calls to WNetGetUniversalName
10.3.05 if 0'd out code about textbooks at line 815
Put message boxes back giving better information if registry reading fails.
1.30.06 removed unused MAXINIT definition, moved this file to interact.dll, changed MEXPORT declarations accordingly
4.7.06 changed itoa to sprintf
4.9.07 changed lines 445 and 449
4.27.07 modified treatment of LANGUAGES (so new languages only require registry changes)
changed assertion at line 1482 to use MAXLANGUAGES, not Initfile.nlang.
8.13.07 modified RegInitialize to not put up a message box if user doesn't have write permission.
Removed the first of two parameters from readinit().
Modifed readinit to call InitializeDefaults if registry reading fails.
Put back the code that was if 0'd out on 9.12.04 so InitializeDefaults will be defined.
Removed set_tocflag.
8.14.07 removed all code dealing with LANGUAGES in registry.
1.15.08 modified readinit to always initialize the defaults before even trying to read the registry,
in case the return value of reading the registry is true even when it didn't work
4.3.08 Changed InitializeDefaults to not set nlanguages
4.17.08 RegGetAllValues had an unused parameter, so I deleted it, and modified the calling code accordingly
Modified RegGetMathXpertKey to set hMathXpertUserKey to NULL if it can't get it and same for hKeyHelpWithMath
GetMathXpertUserKey was never called, so I deleted it.
Set hSubKeys to NULL in RegGetMathXpertKey and checked that it is not NULL in RegInitialize before calling
RegGetAllValues
5.28.09 Added include version.h
Added #ifndef LAB_EDITION
modified readinit()
10.2.09 added conditional compilation for default_installdata, and removed superfluous setting of
InitFile.whichdisk in readinit().
1.4.11 modified RegGetValues to first check if a correctly formatted color string is stored under "Background", and fail if not.
This is intended to prevent overwriting the defaults with garbage from the registry if the user hasn't had sufficient permissions to
write the data into the registry.
1.19.11 Corrected that change.
1.19.11 Added get and set functions for 'webgrades' and 'email', new fields of initstruct.
1.20.11 removed registry key for webgrades
1.23.11 modified set_email and get_email
8.11.11 modified InitializeDefaults to check whether WEBGRADES is defined and use it to set o->webgrades
4.25.13 changed default username and organization.
4.25.13 added code to create the system key if it isn't there already, in GetMathXpertSystemKey
5.3.13 modified init_languages, now that we no longer have dynamically loaded language dlls.
5.20.13 removed all code involving textbooks
decremented EMAIL and NSUBKEYS because TEXTBOOKS (which was 9) is deleted
6.14.13 modified readinit to set InitFile.whichdisk.
Removed CreateMathpertSystemKey, which was no longer used.
1.21.13 split this file, preferences.c, off from registry.c
8.11.17 added SPANISH to init_languages
9.3.17 removed prototypes of unused functions
12.11.23 added #ifdef SVG
2.16.24 removed get_whichdisk()
2.27.24 added DUTCH and CHINESE; modified readinit()
changed initialize_defaults to call DefaultGraphColors
3.1.24 changed nlanguages to 7 in default_install_data, but it's probably never used.
3.2.24 modified init_graphcolors to change axis colors etc. since graph paper is used.
3.5.24 made read_init call GetFactoryGraphColors.
6.23.24 if 0'd out things not used in the Engine
8.8.24 deleted unused variable in init_languages
