MemSize

Description
Also known as "System Resources"

This program provides a digital clock (with date), the elapsed time since your system's last restart, the amount of free virtual memory, the current swap-file size, the maximum amount the swap-file can still grow, the current CPU load (%), the number of active tasks and the amount of disk space free on each of your hard disks. Each figure is updated once per second, or at whatever interval from one to thirty seconds that you wish. Removable disk drives (including CDs) are not supported at this time.

If you'd like to see the program translated into another language, feel free to make your own version of ENGLISH.DOC, ENGLISH.CMD, ENGLISH.RC and ENGLISH.IPF.

Installation on OS/2
Run the installation file ENGLISH.CMD. It will ask you where you want the program stored and whether you want it to be placed in the startup folder. The job will create a program object and place it either on the desktop or in the system startup folder. This object will have all its attributes set up correctly for running the program.

Installation for Win32 platforms
This version of the program is -far- from complete, but a simple version of the SNAPSHOT utility does work. No automated installation is provided, however, so you will need to do the following:

COPY OBJECTS.W32\ENGLISH.DLL MEMSIZEW.DLL SNPSHOTW

History
1.00 - Submitted to Compuserve's OS/2 Forum, early January, 1992.

1.01 - Added single-line border. Removed default TaskList processing, added custom logic.

1.10 - Added ability to hide controls. Added ability to be moved with the mouse, independent of title bar. Added help facility. Removed 'exit' option from system menu (Alt+F4 or F3 does fine). Now searches CONFIG.SYS to find SWAPPATH. Responds to WM_PRESPARAMCHANGED messages, allowing OS/2 2.0's          font, color and color scheme palettes to work with it properly. Added CPU load indicator. Added ability to select which items are to be monitored. Added ability to reset presentation parameters to default state.

1.20 - Restructured program to make status items easier to add. Changed 'Swap-disk free space' to 'Available swap space'. Added disk drive free space items. Optimized window refresh logic. Corrected minor bugs in handling font changes.

1.21 - Fixed bug in computing swap-file size.

1.22 - Fixed bug in computing available swapping space.

1.23 - Fixed bugs in initial sizing and location of CONFIG.SYS.

1.24 - Fixed underflow error in computing CPU load.

1.25 - Fixed bug with determining swap-drive.

1.26 - Switched from using COMSPEC to SYSTEM_INI when trying to determine the boot drive in order to find CONFIG.SYS. There have been users with alternative command-line interpreters altering COMSPEC to point to a different disk drive. Something more reliable was needed. This is still not a perfect solution.

1.27 - Fixed problem with initial positioning under OS/2 1.x.        If SYSTEM_INI cannot be found, look for COMSPEC instead. If that cannot be found, assume the boot drive to be current drive.

1.28 - Fixed problem where title bar and system menu were not being initialized correctly when the program started up with the controls hidden.

1.29 - Now skips removable drives during setup. Now uses the Global Information Segment to determine boot drive, and thereby the location of CONFIG.SYS. Now accepts any color from the color palette. It no longer forces the use of solid colors.

1.30 - Show Spool-file Size option added to program. Fixed bug in adjusting options while program is minimized.

1.31 - Changed to use DosFindFirst2 in spool-file search. Minor clarity changes.

1.60 (08 March 1993) - Added ability to monitor the number of active tasks, according to the system switch list. Fixed bug with attempts to hide controls while minimized. Only checks drive types at startup and at time of NET USE. Precalibrates the CPU load meter if HRTIMER.SYS is available.

1.61 (09 April 1993) - Now checks to see if a drive is remote before attempting to     open it as a complete drive. All remote drives get monitored. Only fixed local drives get monitored. Show drive file system names. Fixed bug in update of drive list. If a drive returns an error during poll, stop trying to poll it. Added item list resource lock.
