Version 1.50
06/06/93
* Added protected mode support for BP 7.0.
* Added Windows 3.1 support.
* Rewrote the DOS Btrieve interface unit BTRV6.PAS to remove unneeded code.
* Renamed Btrieve interface unit to BTRVDOS.PAS.
* Moved all constants into the file BtvConst.pas.
* Defined a DefErrorHandler object type as a descendant of ErrorHandler.
DefErrorHandler has the default error message strings that are stored in the
data segment. Unless a DefErrorHandler is created the error messages will
not be loaded into memory. Version 2.0 will include a new error handler that
reads error messages from a Btrieve file.
* Added ErrorON flag and ErrorsOnOff procedure to the BtrieveFile object. This
provides an easy way to turn built in error checking on and off.
* All examples work under Windows and protected mode.
* Windows data entry example program.
Version 1.51
09/07/93
* Month and Day were backwards in BDateRec
Version 1.52
* Fixed a bug in CheckForBtrieve
* Cleaned up the owner name (password) routines Open, SetOwner, ClearOwner
* Added a demo for owner names
* Added bNoAccess constant for owner names
Version 2.00
12/06/93
* Addded full support for extended operations (Get, Step, Insert).
* Added SetFillValue and GetFillValue procedures to BtrieveFile. SetFillValue
sets the value used by ClearBuffer and ClearKey to clear the data and key
buffers.
* Added support for external programmer defined key buffers to BtrieveFile.
External key buffers allow the programmer to define key records.
* Added GetBtrieveVersion global procedure.
* Added UnloadBtrieve global procedure.
* Added a DiskErrorHandler object. DiskErrorHandler stores all messages
strings in a BtrieveFile.
* Changed BtrieveFile.MakeKey to a virtual method.
* Internal BTV.PAS errors increased to start at 5000.
* Because of new error codes for the Windows version of Btrieve. Certain
errors, which are greater than 255, cannot be toggleD ON/OFF individually.
For those errors greater than 255, use the ErrorsOnOff method added with
version 1.5.
* Made all occurences of OpCode or Op Integer instead of Byte to allow for
locks. This will cause type mismatch errors in existing ErrorDisplay code.
* Changed bOutOfMemory error code to 5000.
* Save uses Get instead of Step reads, to allow for sorting.
* Renamed Recover to Copy.
* Added a new Recover that uses Step reads and writes to a DOS text file.
* Added ResetStation for networks.
* Added justification of ZString and String types.
