Delphi TMagRas Release Notes
Platform Differences and DLLs
TMagRas works with all current versions of Windows by internally checking the version and using different APIs, DLLs and structures as needed. Some functionality is missing from earlier versions, as detailed below. The DUNInfo property in TMagRasCon shows the actual DUN version, based on the rasapi32.dll version number.
Windows 95 to Windows 2000 are no longer supported.
Windows XP - adds a RAS function to delete sub entries, also some extra phonebook entry stuff allowing some of the new properties added in Windows 2000 to be accessed via the RAS APIs.
Windows 2003 - no known differences from XP.
Windows Vista - RAS supports IPv6. RasEditPhonebookEntry and RasCreatePhonebookEntry are no longer supported, RasSetEntryDialParams does not set the password correctly. Applications generally run without administrator rights which prevents updating 'All Users' Phonebooks.
Windows Server 2008 - same as Vista, except programs again have administrator rights as standard.Windows 7 - internally this is version 6.1 (Vista was 6.0) and no substantial differences from Vista, just better IP6 and VPN support.
Windows 2008 RC2 - same as Windows 7, except programs have administrator rights as standard.
Windows 8 - internally this is version 6.2 and similar to 7.
Windows 2012 - same as Windows 8, except programs have administrator rights as standard.
Windows 8.1 - internally this is version 6.3 and similar to 7.
Windows 2012 R2 - same as Windows 8.1, except programs have administrator rights as standard.
Windows 10 - internally this is version 10.0 and similar to 7 and 8.
Windows 2016 - same as Windows 10, except programs have administrator rights as standard.
RAS and Unicode
Windows NT4 and all later versions have supported Unicode internally, effectively two byte wide characters with the potential ability to display many thousands of symbols, including Greek, Russian and Far Eastern languages at the same time, provided the Windows OpenType font contains all the symbols. Unicode characters may be used in many places, file content, file names and paths, RAS entry names and logons, etc.
Although Windows itself supports Unicode, many applications are restricted to working in ANSI, which is one byte wide characters, so interaction with the Windows causes a translation to and from ANSI using the current code page. During conversion to ANSI, non-compatible Unicode characters may be substituted by a failed character which is usually ? and illegal in file names and paths. So ANSI only applications are unable to open files with non-compatible Unicode characters, and RAS entries will similarly fail.
Delphi 2007 and earlier primarily supported ANSI strings and Windows APIs. Although the widestring type was available, there was no wide TStrings for lists and sorting and the VCL was ANSI, so it was really only possible to support Unicode using third party component libraries.
Delphi 2009 now fully supports Unicode, with types String=UnicodeString and Char=WideChar, and the VCL handles Unicode fully. Beware updating earlier applications from earlier Delphi releases needs careful checking for all string and pointer usage, particularly PChar, Char, Chr, Move, SizeOf and FillChar whose behaviour may be effected by Unicode.
TMagRas 5.70 and earlier use the ANSI versions of the RAS APIs, which means entries can not be created with Unicode characters outside the current ANSI code page. Any entries created with such Unicode characters by other applications will be listed by TMagRas with failed characters (?) and will be unusable for calls to other RAS APIs. TMagRas 5.40 and later have been updated to support Delphi 2009 and later.
TMagRas 6.00 and later primarily support only Delphi 2009 and later, with full Unicode support by using the WideString versions of the RAS APIs and the UnicodeString type. TMagRas 6.00 and later will work with earlier versions of Delphi, but only with ANSI strings. All the TMagRas 6.00 widestring RAS units have W suffixes to keep them separate from the old units, but the component names are the same so only one version can be installed on toolbar at the time. To simplify the source code, support has been removed from TMagRas 6.00 for Windows 9.x and NT4, which are now 10 years old and rarely used, so TMagRas 5.60 should be retained if support for these is still needed. The main demo application is now RASDEMO6. TMagRas 6.00 and later are only available to source code licensees, no free compiled objects version is available.
Changes in TMagRas Release 6.33 and 5.73
1 - Updated GetOSVersion (magsubs1) to recognise Windows 10 and Windows
2016. Updated magrascon to recognise Windows 10 and later. Since this is a
cosmetic change, not all the packages have been rebuilt for 5.73, but
putting magsubs1.pas in the source directory will use the new version.
Updated manifest to support Windows 10 and add it as resource file.
Changes in TMagRas Release 6.32 and 5.72
1 - Updated GetOSVersion (magsubs1) to recognise Windows 8.1 and Windows
2012 R2. Note only magsubs1 dated March 2014 or later correctly detects
these two versions of Windows, Microsoft has changed an API to no longer
correctly return the OS version so a workaround was needed.
Changes in TMagRas Release 6.31 and 5.71
1 - Updated GetOSVersion (magsubs1) to recognise all editions of Windows
8 and Windows 2012.
Changes in TMagRas Release 6.30 and 5.70
1 - Fixes for 64-bit compiler, mainly in magrasapi where DWORD was often
used instead of pointers (which are 64-bits in Win64). Note the various RAS
dialogs do not seem to display in Win64 applications, and MagLsaPw
does not yet run on Win64, still under investigation.
7 - Currently, only the Delphi 2007, 2010, XE and XE2 compiled objects have been similarly updated for 5.70, other Delphi versions are still 5.60 or older objects.
Changes in TMagRas Release 6.20 and 5.60
1 - Fixed cast warnings for Delphi 2009 and later
3 - Updated all the example applications to support TMagRas version 6,
they all have the suffix 6, see example6.txt.
Changes in TMagRas Release 6.10 and 5.50
1 - GetTransCaps now creates a blank 'My Location' if missing to avoid the Windows 'Location Information' dialog appearing the first time RAS is accessed on a newly installed OS. Note this feature needs administrator rights to write to HLM registry keys and will silently fail otherwise
2 - DefCountryId is now set from LOCALE_ICOUNTRY using GetLcTypeInfo instead of LOCALE_IDEFAULTCOUNTRY which is obsolete.
3 - Recognise Windows 7 and 2008 R2, but note that no Windows 7 RAS extensions are currently supported in TMagRas, they mostly relate to IP6 and VPNs, rather than dial-up. Internally, Windows 7 is handled as Vista.
4 - Added packages for Delphi 2010, which is version 14
Changes in TMagRas Release 6.00
1 - Support RAS ideChar APIs and Unicode for Delphi 2009 with new MagRasxxxW units Removed support for Win9x and NT4, both 10 years old now. The units may be compiled under Delphi 7 to 2009, but only support Unicode properties under Delphi 2009 where String=UnicodeString.
2 - The TEntryRec has a new element DialParamsUID read from the rasphone.pbk file.
3 - Added a new unit MagLsaPw that may be used to find the RAS credentials (username and password) from the Local Security Authority (LSA) protected subsystem of Windows that maintains information about all aspects of local security on a system, saved in the registry under the protected key: HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\. This overcomes the limitation in Windows 2000 and later where the RAS APIs are unable to read clear text passwords. A new DEMOPW application lists all RAS entries with the credentials. Currently, the MagLsaPw unit has functions to write to LSA, but not to specifically update RAS credentials.
4 - There is another new demo program PSTEST that demonstrates reading from the Protected Storage service, another protected part of the registry used to store confidential information, specifically Outlook Express credentials, but which may be used to save application passwords.
Changes in TMagRas Release 5.40
1 - Updated all the components
and demos to support Delphi 2009. TMagRas has only ever supported the ANSI
RAS APIs to support western languages, and not the Widestring/Unicode APIs
needed for Asian countries. This version has changed most String data types to AnsiString and Char to
AnsiChar, to be compatible with Delphi 2009 while remaining fully compatible
with Delphi 6 and later. Beware this means Delphi 2009 will generate lots of
string cast warnings during compilation as Unicode and ANSI strings are
converted between each other. A number of ANSI only string functions have
been added (TrimAnsi, UpperCaseAnsi, AscToIntAnsi, etc) to avoid
2 - Fixed a bug that meant MagRasGetEntryRecs did not read all the entry properties for entries with non-ASCII characters, due the phonebook files being saved in UTF-8 and not ANSI format.
Changes in TMagRas Release 5.30
1 - Added bDefaultCreds property for TMagRasCon and TMagRasEdt, which should be set true before calling PutDialProps, GetDialProps, PutDialParams or GetDialParams functions to set user name and password for 'anyone who uses this computer', which may be needed as well as setting Phonebook Location to all users on Vista./p>
Changes in TMagRas Release 5.21
1 - Ensure that the MagRasPhoneFiles array is completed with default phonebook names when the TMagCon and TMagEdt components are created, rather than when RAS is initialised, so setting PBLocation always sets the PhonebookPath file correctly.
2 - It's no longer possible to set the PhonebookPath property except on NT4, to avoid conflicts with PBLocation.
3 - Updated all the example applications with PBLocation so they all work on Vista.
4 - Updated MSIEDefConn for Vista.
Changes in TMagRas Release 5.2
1 - Finally tested on Windows Vista RTM and Longhorn (Windows Server 2008) beta 3. Unfortunately Microsoft no longer supports several RAs APIs in Vista, but has not documented this in MSDN. Also, most application now run without administrator rights which means connection entries in the 'All Users' phonebook can not be edited. So this release changes the default for new entries to the 'Current User' phonebook for Vista and later. Note that Longhorn programs have administrator rights as standard.
2 - In the Demo4 program, moved Windows version information to the Network tab and show Windows version information as well, also use IsProgAdmin (in magsubs1) to show whether the application has admin rights and can therefore edit 'All User' phonebook entries. If a non-admin user attempts to save a 'All User' entry, the RAS APIs should fail with 'access denied', but this is not reliable and sometimes the API seem to work. Note that both Vista and Windows Server 2008 are Windows version 6.0 with the ProductType differentiating them (similarly to NT4 Workstation and Server).
3 - TMagRasCon and TMagRasEdt each have a new PBLocation property which should be set to REN_AllUsers or REN_User before calling most methods, Win2K/XP default to REN_AllUsers, Vista/2008 to REN_User. Generally, this property is copied from the PBLocation in TEntryRec which is returned when enumerating the connection entry list (MagRasGetEntryList). Setting the PBLocation property automatically sets the correct phonebook file name. If your application specifically set the phonebook file path, this code should be skipped and replaced by setting PBLocation.
4 - In the Demo4 program, Quick New now allows the phonebook location to be set. Note the example programs have not yet been updated with PBLocation.
5 - The CreatePhonebook and EditPhonebook methods that bring up Microsoft dialogs now call RasEntryDlg since the original RAS functions no longer work in Vista. The Demo4 program also has new buttons to bring up the Microsoft DUN and Dialling dialogs.
6 - PutDialProps and GetDialProps in MagRasEdt now use RasPutCredentials and RasGetCredentials similarly to PutDialParams and GetDialParams in MagRasCon, so work correctly with Vista.
7 - The IP Helper units have been removed, they now have their own package distributed separately. There is a new package MagentaSubs that contains magsubs1, magsubs4 and magclasses, which is common to other Magenta components. Packages for Delphi 4, 5 and 2005 are no longer supplied since these compilers are rarely used. Delphi 2006 and 2007 both use the magras100.dpk.
Pending - allow for wrapping performance counters over 4 gigs.
Changes in TMagRas Release 5.1
1 - Added initial support for Windows Vista (and maybe Longhorn), by updating changed APIs. Vista supports IPv6, but TMagRas does not yet, due to lack of any way to test it.
2 - PutDialProps and GetDialProps withe NT4 and later now use the RasPutCredentials and RasGetCredentials APIs instead of RasSetEntryDialProps and RasGetEntryDialProps. This change seems to allow passwords to be sometimes saved in Vista Beta 2, but currently only for connections created by some Vista dialogs. Hopefully Microsoft will fix these issues for the Vista release candidate due in September.
3 - Made some literals in magsubs1 conditional, which should allow TMagRas to be used with C++ Builder.
Changes in TMagRas Release 5.0
1 - Validate the SubEntry before dialling.
2 - To simplify distribution, the IP Helper components are now distributed separately, ditto the WMI and SMART components.
Changes in TMagRas Release 4.94
1 - Fixed a problem on Windows XP and later that meant details of only the first connection returned by GetConnections was accessible, this only effected multi-link and VPN over dial-up.
2 - Added MSIEAutoDialOpt to set all three MSIE auto dial options, and fixed MSIEDefConn to work properly on XP. The Network tab of the RAS demo program reflects the new auto dial options.
3 - Added SCutSpecLinkEx and SCutAddLinkEx to create improved DUN short cuts, with configurable icons and description, and to
make the short
4 - TMagRas has been thoroughly tested on Windows 2003, but there are no new RAS features and no changes have been made.
Changes in TMagRas Release 4.91
1 - TMagRas now supports an unlimited number of RAS devices, previously there was a limit of 30 devices. This change was primarily needed to allow TMagRas to be supported on Windows 2003 beta (effectively the server version of Windows XP), since about 260 devices are returned, mostly identical VPN devices. Something similar happened with W2K beta, so these extra VPN devices may disappear before the final release. Quick testing on .NET server did not show any other problems.
Changes in TMagRas Release 4.90
1 - TMagRas now supports an unlimited number of connection entries, previously there was a maximum limit of 100, after which none were displayed atall. This was done by making MagRasEntryRecs a dynamic array (Delphi 4 and later). There is a new test program to create and delete multiple DUN connection entries, up to 999 at a time (but don't try that many). This is primarily to allow RAS applications to be tested with hundreds of test entries.
2 - Added typeBroadband to TPType for Windows XP.
3 - Updated the main demo application to allow multi-link ISDN to be tested. A new 'ISDN link' drop down list allows all links to be dialled, or a single link only. The second link can then be dialled later, to provide bandwidth on demand. Note that not all ISPs will allow a second link to be added later, it is usually a problem where the two calls get answered by different access servers which can not multilink them. There are currently cosmetic problems in the demo monitoring the second link because the connection handle changes during dialling, which seems very bizarre. More testing is being done.
4 - IPHelper and it's demo application have been improved to show DNS server allocated to specific adaptors.
Changes in TMagRas Release 4.80
1 - Added the ability to add shortcuts (or links) to the windows desktop for both programs and non-file object such as DUN connections or printers. These functions are in magsubs2. Special directories, such as Printers, can also be indexed. There's a new demo/test program for these functions called scuttest.
2 - Added TConnectionList.CheckIndex which is used to validate the argument to all Connections properties, to avoid possible 'listindex out range' errors accessing connections that have already dropped.
3 - Moved MagRasOSVersion to magsubs1 so it's available without initialising RAS APIs. This may need changes to applications that check MagRasOSVersion to import the magsubs1 instead of magrasapi.
4 - Corrected MSIEDefConn to set the correct registry key for a default connection in Windows XP.
5 - Fixed major memory leaks in the IP Helper IpHlpIfTable and Get_AdaptersInfo functions, created IpHlpAdaptersInfo which returns TAdaptorRows.
6 - Currently MagRasAdm may only be used to monitor incoming calls to Windows NT4 RAS Server. With Windows 2000 (and .Net Server), RRAS (Routing and Remote Access Service) is used instead. Most of the work on monitoring RRAS has now been done, unfortunately it has not been fully tested since our Windows 2000 server with RRAS installed does not respond as expected to the APIs. It's not known if this is a problem with the underlaying windows APIs or our implementation of them. The new unit is included with this distribution as magrasadm-new.pas in case any users have RRAS working and need this functionality before we are able to finish it properly.
Note that 4.80 is only available as source for registered users, and that the help file has not been updated from 4.71.
Changes in TMagRas Release 4.71
1 - Fixed potential bug in TMagRasCon.Create checking the RASAPI32.DLL version failed if the DLL is not installed and raised an exception, bug was introduced in 4.7.
2 - On W2K and XP, make sure that both phonebook files exist, creating if necessary. Create path if necessary before creating empty phonebook file.
3 - Added DirectoryExists and ForceDirs to Magsubs1 to support previous fix, which avoids linking in FileCtrl which brings in the dreaded Forms and bloats many projects.
Changes in TMagRas Release 4.7
1 - Tested on Windows XP final build 2600, no changes needed since 4.62.
2 - Added IsDestReachable and IsNetAlive functions using the Synchronization Manager SENSAPI.DLL that comes with MSIE5 and later. These allow a quick test for internet connectivity, but are not totally reliable.
3 - Added MSIEAutoDial and MSIEDefConn which allow some MSIE Internet Options to be set, effectively enabling auto dial for specified entry.
4 - No longer provided compiled DCUs for Delphi 3 since Int64 types are now used in the demo program to display statistics to 4 gig. 4.61 will remain available for D3, or the source can be licensed and modified to remove Int64s.
5 - Installation of the compiled DCUs has changed slightly, all the files necessary are now in the compiler version subdirectory, to avoid copying any from the root (this means several duplicate files in the archive, but eases installation).
6 - Added TCPIPMon to the demo programs to illustrates use of the IP Helper APIs, corrected OS version check in EXPERF for Windows XP.
Changes in TMagRas Release 4.62
1 - Added support for Windows XP, tested on RC1 build 2505. XP appears to be fully backward compatible with Windows 2000 so old applications should continue working OK on XP with earlier TMagRas releases. But XP adds new elements to the RASCONN and RASENTRY structures, which are TRasConnWXP and TRasEntryWXP. MagRasOSVersion nows returns OSWXP for Windows XP, if your application uses this (possibly for performance statistics) it will need to be changed. TConnectionList has new Flags and LogonSessId properties to support multiple users being logged onto windows at the same time. TMagRasEdt has 10 new binary and 6 other properties, mostly seem to work, but no proper MSDN documentation yet (most of the new stuff was in Windows 2000, but never supported by RASAPI32)
2 - Deleting subentries on Windows XP only, if the number of subentries is reduced. On earlier OS, it's necessary to delete the entry before saving it to delete old subentries, but this causes the password to be lost so is not done automatically by this component.
3 - Corrected MagRasGetEntryRecs to convert ISDN11-0 to ISDN1 on Windows XP.
4 - In MagRasPer, performance statistics now allow for Win9x DWORD counters wrapping after 4 gigs of total data since a reboot, but maximum data for a session is 4 gigs. NT4/W2K should have been 4 gigs already, but that assumes the Microsoft APIs wrap correctly. Yes, 4 gigs on a modem is a lot, but some ADSL and cable modems also use RAS and can do that in 24 hours.
5 - The TMagRas distribution now includes three new files, iphelper.pas, iphlpapi.pas and dnshelper.pas. These were not originated by Magenta Systems, but have been heavily updated and tested on recent OSs. IP Helper is only available for Win98, WinMe, W2K and XP, although some functions work on NT4 with SP5 or greater. It is included here since it allows access to dynamic DNS server addresses and provides performance statistics for network adaptors. dnshelper uses other techniques to get DNS info for Win95 and NT4. The DNS server address is primarily of interest to those using a DNS lookup component.
6 - The RASDEMO4 program has been updated to support the new RAS features in Windows XP. The Online listView shows connection Flags and LUID (for multiple logons). Full Properties has a new XP tab showing new entry options. A new Network tab shows some stuff from the IP Helper API including dynamic DNS addresses for the PC.
Changes in TMagRas Release 4.61
1 - Recompiled with the final Delphi 6 release.
2 - Fixed a possible bug in MagRasGetEntryList that could have raised a error if there are installed connection entries.
3 - Added GetMACAddresses to return one or more network card MAC address for the local or others PCs, see DEMO4.PAS for usage (it's not in the help file yet).
Changes in TMagRas Release 4.60
1 - Improved the means of listing phonebook entries (aka DUN connections), in order to return extra information for W2K, and also to get common information for all entries with a single function call. This is all done with new functions (not a component) in MagRasEnt, with the MagRasEntryRecs data array being filled by MagRasGetEntryList (minimal info) or MagRasGetEntryRecs (detailed info). Use of the new functions is illustrated on the Entry List tab in the demo program. On NT4/W2K the new functions read the physical phonebook INI files directly since this is up to 100 faster than using API calls. GetPhoneBookEntries is still available, but now uses the new functions.
MagRasGetEntryList fills MagRasEntryRecs with sorted entry names and phonebook paths (W2K only), MagRasGetEntryRecs is similar but also fills phone number, devices and ports, MagRasGetPhoneBookFile loads MagRasPhoneBookInf from rasphone.pbk files, MagRasIsPhoneBookNew checks if rasphone.pbk files have changed since last read, and MagRasGetEntryKey returns keyed data for an entry in MagRasPhoneBookInf.
2 - Finally got around to testing PhoneBookPath, simplified some related code. On W2K, PhoneBookPath must be used to save the entries in the correct phonebook, PhoneBookPath is found from the new MagRasEntryRecs array once MagRasGetEntryList or MagRasGetEntryRecs has been called. To save a new entry on W2K, get the correct phonebook file name from MagRasPhoneFiles (see Demo program). Only administrators can save entries in the All Users phonebook.
3 - Added a new component TMagRasAdm which uses the RasAdmin APIs to monitor incoming RAS connections to NT4 Server, they don't work with NT4 Workstation incoming calls. These APIs provide similar functionality to the Remote Access Admin application, showing which ports are configured to answer calls, and the status of those in-use. Note there is another set of APIs for RRAS (Routing and Remote Access Service) that are not currently supported by TMagRasAdm. The APIs work in both NT4 and W2K, but only appear to monitor NT4 Server (they work across a LAN).
4 - Moved some common functions to MagSubs1 and MagRasEnt to avoid duplicated code.
Changes in TMagRas Release 4.51
1 - Removed ConnectEx/ConnectNT 4.50 fix for fSubEntry not allowed as zero so that W2K will again dial multilink.
2 - Default fSubEntry on creation to 1 so W2K does not dial multilink (unless set to 0).
3 - Recognise Windows Whistler (aka 2002 or net), only basic testing so far, seems OK. Whistler added one new RAS API, RasDeleteSubEntry, but this is not supported yet in TMagRasEdt.
4 - Corrected DisConnectEx so the timeout actually works and state events are notified while waiting for timeout. Existing applications may now get one or more events that should have happened before, but didn't.
5 - Added TEncryptionType = encryptOptional which is the 'Typical' default in W2K, and prevent the Windows dialog showing custom encryption.
6 - Added bCustomScript property for W2K.
7 - In TAPI event handler, only de-allocate calls in idle event, not when disconnected.
Changes in TMagRas Release 4.50
1 - All literals in the RAS and TAPI components have been moved to resource strings for translation in magrasstr.pas and magtapistr.pas. The Delphi wizard can then be used to convert the strings into a resource file, or the files could be changed to functions which return different languages dynamically.
2 - Added onStateEvent (as an alternative to onStateChanged) which buffers dial callback state messages to avoid dialling being blocked and possible reentrancy issues (since callback can not be stopped). It uses a queue to avoid missing rapidly changing events. The event returns TRasStateRec with all the state properties, rather than reading component properties that may have already been changed by subsequent state changes. Note that CurDevName, CurDevType and ConnectPhoneNr are only set if the event source is status (not dial).
This change has fixed a long term cosmetic problem in the demo program where a second row appeared incorrectly in the ListView while a call was being dialled.
3 - GetConnectStatusEx now updates CurDevName and CurDevType since the W2K final now sets these correctly. ConnectPhoneNr is returned by NT4/W2K. These settings are very useful to see if RAS connected using the device specified in the phonebook entry (it may choose others) and to see what phone number was really dialler (note it's the dialable format usually starting with T (for tone dialling) and may include a calling card number, so it not really suitable for displaying to users.
4 - Added ConnectNT similar to ConnectEx but NT4/W2K only, supports dialextensions for paused states and speaker on/off. The handle passed must be zero to dial a new call, a non-zero handle will resume dialling a call that has been paused for a callback number or authentication. Note that paused states have not been tested yet!!
5 - Fixed an occasional problem in NT4 where performance statistics failed by optionally using PDH.DLL (which must be redistributed) when the normal registry version fails. Tests show that only the RAS Total object returns any data, so the RAS Port object code is currently disabled.
6 - In the TAPI component, on NT some ISDN had channel names starting from 0 not 1, so now allocate ports sequentially, 1/2/3/4 Win9x/NT, 2/1/4/3 W2K. Also minor change to ensure call not returned if deallocated. Increased VPN modems to 30. OnTapiStatus now sets tinfo2 to disconnect reason.
Changes in TMagRas Release 4.41
1 - Corrected Str2IP so that it correctly converts IP addresses with a single last digit and without trailing spaces (function rewitten). This problem meant that PutAllEntryProps sometimes ignored IP addresses, unless they had trailing spaces (which TMaskEdit added in the demo programs).
2 - Added IsIPStr to check an ASCII representation of an IP address is valid.
3 - Improved validation of IP addresses, stop numbers > 255 and zero first.
4 - In TMagRasCon, CreatePhonebook and EditPhonebook now both need Application.Handle passed as a parameter. This avoids the Forms unit being included in some apps. Graphics and Control units now conditional as well to ease linking.
Changes in TMagRas Release 4.40
1 - Added a help file and seven new simple example programs.
2 - Recognise Windows ME (sort of)
3 - Compiled as TComponent again to allow use as an NT service. Previously TMagRas was descended from TCustomControl to allow use in an ActiveX (and may still be conditionally compiled by changing the CUSTCNTL directive in the source). Warning: this change means that applications compiled with TMagRas 4.0 to 4.3 will throw up errors on the Height and Width properties that are now removed (but were never used).
4 - Minor tidying up of unused properties and code.
5 - Added DPK package files to build a package from the TMagRas and TMagTAPI components, to ease installation. BPL/DPL/DCP files are not supplied since these would double the zip size.
Changes in TMagRas Release 4.30
1 - This version has been tested with Windows 2000 build 2195, which is the final retail version. GetDialParams no longer returns the connection password, but what Microsoft call a 'handle' that is 16 asterisks. Passing this 'handle' back to SetDialParams causes the existing password to be unchanged, and so Connect causes the existing password to be used. So if your applications checks that what is saved is also returned, it will fail under W2K. Avoided what appears to be a bug in W2K whereby dialling properties were lost after saving an entry and it's subentries - now save a second time after doing the subentries, silly but it works.
2 - Added Str2IP to TMagRasEdt to convert and validate IP addresses.
3 - Added DUNVersion and DUNInfo properties to TMagRasCon to return the DUN version. A look-up table uses the build of RASAPI.DLL (in DUNVersion) to create a version description like 'DUN 1.1/Win95/OSR2' (in DUNInfo).
4 - Corrected PhoneNumber being ignored for dialling (error in 4.00 and later), so the number dialled was always the default from the phonebook entry. You should set PhoneNumber to blank before calling Connect to use the default number.
5 - GetEntryProperties now completes LocalPhoneNumber not PhoneNumber, to avoid confusion when dialling calls.
6 - Added GetTransCaps which gets modem and country dialling properties so we can offer better display of canonical numbers (we need to know the local city code). The function completes DialProps, DialLocation, DialCard and DialCountry for the current dialling location. Full informtation on the content of these records is in the TAPI API info.
7 - Added UseCountryAndAreaCodes and PromoteAlternates properties for use with dialling properties, and EntryOptions which is 32-bits of flags where other properties are needed.
Changes in TMagRas Release 4.20
1 - Make sure Win9x modem device configuration set correctly for new or edited connections/phonebooks. Previously an error would appear when attempting to access modem properties when editing a phonebook using the normal dialog. Also set default modem device configuration when updating Win9x connections, if it's missing.
2 - Structures are now available to edit the Win9x modem device info, but the properties are not currently being processed.
3 - Corrected GetEntryProperties canonical phone number on NT4/W2K when area code set but dialling properties disabled.
Changes in TMagRas Release 4.10
1 - Performance statistics now support two adaptors for Win9x, so that the devices used for the first two connections can now be monitored separately. Note that Windows does not say which adaptor is monitoring which connected, so they must be allocated sequentially.
2 - A performance statistics reset now clears all arrays so 'all' stats restart correctly on NT4.
3 - Added DefCountryId propertry to ease created connections/phonebooks.
4 - No longer store component version on form.
5 - TotSubEntries is now set as 2 for Win9x ISDN multilink, but there are no modem/dial details since the RAS API was never completed by Microsoft.
6 - Changed TConnectionList.Clear to ClearFree to avoid overwrite problem in D3.
