- About LockVol™ - Version 1.5 - January 3, 1994
-
- LockVol is a Control Panel device that can be used to test software handling of
- locked volumes, local or remote. With the use of System 7 and File Sharing,
- LockVol may come in handy for those trying to test their software. LockVol
- displays a popup menu containing all volumes in use by your Mac and allows you to
- change the status of each volume from unlocked, to having a software or hardware
- lock. Changes made in the Control Panel are immediate and remain intact until
- you change them back or re-mount the affected volume. The status of the startup
- volume is restored after a reboot. All other volume status’ are lost after a
- reboot.
-
- LockVol works under System 6.0.5 (and up) and System 7. No known problems have
- been reported other than the ones you can create yourself by locking volumes that
- weren't originally locked.
-
- LockVol is freeware. Permission is granted by the author for personal or
- electronic distribution as long as no fees or charges are received for it.
- LockVol remains the copyright of dEVoN Hubbard.
-
- How to Install it
- ---------------
- Simply drag it into your System Folder if your using 6.0 or before; or put it in
- your Control Panels folder if your using 7.0 (or for that matter anywhere you
- want under System 7). If you are using System 7 and are going to be testing
- extension (INIT) code handling of a locked startup volume it is suggested you put
- LockVol in your ‘Extensions’ folder and put an alias to it in your ‘Control
- Panels’ folder. This will ensure LockVol gets run before most extensions due the
- space preceeding the file name.
-
- •--> WARNING <--•
- If you are running System 7 and attempt to lock the startup volume while File
- Sharing is running, a dialog informs you that the ‘Users & Groups Data File’
- should be backed up before locking the startup volume. This warning is necessary
- as the System software does not like the volume this file is on suddenly becoming
- locked. This file will become damaged so you should make a copy of it before
- locking the startup volume if File Sharing is running. The Finder may tell you
- this file has been damaged if you lock the volume while File Sharing is running.
- Having a backup of it will save you alot of time.
-
- Version History
- --------------
- -1.5
- 1. Now ignores invalid volumes that appear in the VCB queue. For instance, when
- used with System 7 Pro (e.g. PowerTalk) the "Mail Enclosures" volume is not
- included in the volume popup anymore.
- 2. A little known limitation has been removed. LockVol now supports an unlimited
- number of volumes (limited by memory and system software limitations). It
- previously only supported 30 volumes.
- 3. Internal changes were made to speed up the building of the volume list and
- processing of selections from the volume popup menu.
- 4. Code size has become smaller yet.
-
- -1.4
- 1. Now recognizes changes in volumes mounted and unmounted while the Control Panel
- is open. Previously, if you had LockVol open and mounted/unmounted a volume(s),
- you had to close and re-open the Control Panel for the change in volumes to be
- recognized.
- 2. Added small color icons for correct viewing with the Finder by Small Icon.
- 3. The ‘Show Startup Icon’ check box now dims (with the other controls) when
- another
- window is the active window.
-
- -1.3.2
- 1. Corrected a bug that wouldn’t display the popup menu under extreme low-memory
- conditions.
- 2. Code size has become smaller yet.
-
- -1.3.1
- 1. Optimized code and reduced overall size.
- 2. Popup menu now ignores characters in volume names that could represent a
- command key equivalant (meta characters). Volume names like ‘SE/30’ would be
- displayed like ‘SE0’ with a ‘CMD-3’ next to it. This no longer happens.
- 3. All controls (popup menu, radio buttons) now disable/enable when the cdev
- window is activate/inactive. (Big deal… nice cosmetics).
-
- - 1.3
- 1. Copyright notices and resources changed to reflect ownership of LockVol by the
- author.
-
- -1.2.1
- 1. Corrected a bug that “sometimes” showed the startup icon even if the ‘Show
- Startup Icon’ box was not checked in the Control Panel.
-
- -1.2
- 1. Added a startup icon that represents the startup volume being locked or
- unlocked.
- 2. Added a ‘Show Startup Icon’ check box to the Control Panel.
- 3. Corrected a popup display problem that only occured under system 6.0.x.
-
- -1.1
- 1. Identical in operation to version 1.0.1 but this version was rebuilt with Think
- C 5.0 and contains smaller code.
- 2. The area of the control panel that displayed the About… box has been increased
- to cover the entire top of the window. Some people didn't know the about was
- there. Just click.
- 3. A background mask has been added to the icon behind the word ‘LockVol’ so it
- will show up better if placed on your desktop.
-
- - 1.0.1
- 1. Corrected a display problem with the popup menu when ran under System 6. The
- menu is created at a pre-defined width. Short volume names caused a display
- error in the popup menu. The pre-defined width was displayed initially then
- resized (smaller) to the longest volume name. This sometimes left a double image
- of the popup menu rectangle. Note, that the menu worked fine even though this
- visual problem existed.
- 2. Added an arrow cursor to the Control Panel for use under System 6. The
- Control Panel now has an arrow cursor instead of a cross hair (plus sign) cursor.
-
- - 1.0
- 1. The logic that detects if File Sharing is on has been changed to detect in a
- more accurate manner.
- 2. All versions information has been changed to reflect this as a final release.
-
- - 1.0b6 (Not released to the public)
- 1. The System 7.0 warning about File Sharing now only appears if File Sharing is
- running at the time you try to lock the startup volume.
-
- - 1.0b5
- 1. Added a warning dialog for System 7.0 users who try to lock their startup
- volume. See information above about System 7 warning.
-
- - 1.0b4
- 1. The status of the startup volume is saved and restored during startup (by INIT
- code). Only the startup volume status is maintained. The new INIT code patches
- nothing, and is only memory resident during INIT time.
-
- - 1.0b3
- 1. About dialog now centers correctly on non color QuickDraw and non 7.0 systems.
-
- - 1.0b2
- 1. Corrected a bug in dialog handling that caused the Dialog Manager to write to
- address zero. This wasn't causing crashes or volume mishaps but could have
- caused other problems.
- 2. Also added an About… dialog to the cdev. Triggered by clicking on the LockVol
- icon in the Control Panel.
-
- - 1.0b1
- First public release of LockVol.
