Replica Revision History
12-03-94 ■ Version 1.02
. Updated context-sensitive help routines and values.
. Added a conversion routine to automatically convert data
files from version 1.00 and 1.01 to version 1.02. This is
necessary because of the date field that was added, as
described below.
. Added a date field to the database to store the date when
the disk image file was originally created. This date is not
displayed or accessed at this time. That feature will be
added to a future version.
. Disabled the display of "Swapping in..." and "Swapping out..."
messages from being displayed when the compression and/or
decompression processes are invoked.
. Fixed a problem where Replica could not find the image file
to recreate a diskette after a file had been decompressed.
This problem only occurred if image files were stored in a
directory other than the Replica program directory.
. Added an option to allow the user to delete a file from the
hard drive when an associated record is deleted from the
database. After deleting a database file, a prompt is
displayed to give the user the opportunity to delete the
file.
. Added a system to the Copy Disk To File screen that allows
Replica to remember the previous settings between disk
creations. This is useful when creating a series of disk
images for a particular program. This is the default. In
order to clear the settings, a "Clear" button was added.
When selected, this button restores the default values, and
sets all description fields to empty.
. Integrated the use of up and down arrow keys on all
dialog screens. This will allow users to use these keys
in place of Tab and Shift-Tab.
. Removed the use of overlays for Replica. Since error
messages such as "insufficient memory" continued to
occur from time to time during the compression process,
we created a separate file called REPZIP.EXE that contains
the compression and decompression routines. This executable
file is simply called when it is needed. This reduced the
size of REPLICA.EXE by about 45K. When REPZIP.EXE is
executed, Replica is swapped out to EMS, XMS, or disk, thus
leaving a large amount of free memory for the compression
process to occur. This should virtually eliminate all
"insufficient memory" error messages from occurring.
11-28-94 ■ Version 1.01 (Internal BETA Version, Not Released.)
. Added a message box that will be displayed when an image
has been created, to display the total size of the image
file and the compressed file (if a compressed file was
created). This will give the user an idea of the total
compression that was achieved on during the compression
process.
. Added a "Beep When Done" option to the Settings, Defaults
screen, and modified the code to beep when a disk image
has been copied to a file, or when a new disk has been
created from an image file.
. Added a "Defaults" screen to allow users to modify the
default values for the disk drive, drive type, disk image
path, and compression setting. When the Copy Disk To File
and Copy File To Disk screens are displayed, the default
values are used.
. Fixed a problem where a compressed (.ZIP) image file would
not be placed in the same directory as the original (.RIF)
image file. Instead, the compressed file would be placed in
the default Replica sub-directory. Now, the compressed file
will reside in the same directory as where the original image
file was created.
. Removed commands that allowed users to edit records directly
from the browser screen. Now, all maintenance should be
performed from the Database Maintenance screen.
. Added a new menu option specifically for the purpose of
database maintenance. This allows users to view and
edit existing entries, as well as create new ones. (Users
may want to create a new entry if they accidentally delete
an entry.)
. Changed the operation of the Search button. If the user
does not select a record, but presses Escape instead, the
browser will no longer put a blank entry in the "File To
Read" field. Instead, it will leave the existing entry
unchanged.
. Fixed a problem where the columns in the database browser
screen were not being truncated properly if descriptions or
paths were longer than the column display width.
. Added a warning message to alert the user if a file already
exists before attempting to recreate or overwrite it during
the Copy Disk To File process.
. Added a prompt before starting the copy process to remind
the user to enter a disk into the disk drive.
11-21-94 ■ Version 1.00
. Initial release of Replica.
