7. History
1. Description
==============
This program was written to fulfill my need for a VGA-based audio-cd player
for DOS. It seemed that all the nice CD players were written for windows and I
found nothing for DOS. Since I don't like using the mouse in text mode, I wrote
a graphic player.
The program has a very simple interface and includes all the buttons one
would expect to find in an advanced CD player as well as a blank screen saver.
The bottom row of buttons corresponds to usual commands (e.g. stop,play)
where the play button serves also as pause (toggle).
The eject/close-tray button is on the right of the time display. When
ejected or not ready, all buttons (except eject and PWR) are grayed (whited).
The top row of buttons contains special purpose buttons, which are (from
left to right) : Power, Track display(enables to select a track), Statistics
display(Show totals and progress bars), Direction(Toggles between increasing or
decreasing time),Play mode (sequential, ordered or loop),Volume control,Mute and
finally - About.
All the top row buttons are togglers (except PWR, of course).
NOTE : Volume control will work only for those devices that support it. It does
not make use of the sound card, therefore, the sound card itself should
be set to it's maximum level to get the full scale of the volume bar.
2. Instructions
===============
I will provide instructions only for what isn't obvious.
2.1. Screen saver
-----------------
Will either operate after a specified time (see configuration) of no
movement or when the mouse is moved to the upper-left corner of the screen and
remains idle there for 1 second.
Moving the mouse or pressing a letter key on the keyboard will shut off the
screen saver and return the program to the screen.
2.2. Configuration
------------------
Run cdconfig to change your defaults. Note that cdconfig modifies your
executable, so don't run it after compressing cd-v.exe.
When in color configuration, you will have to specify your prefered colors
for every item in cd-v. Most names in the configuration may not be obvoius and
may need some explaining :
Button Face - Button surface
Frame Face - Frame surface
Background Color - Background color for entire screen
Screen Color - Color for main data screen
Title Color - Color for background of the titles of boxes
Active Text - Color for active text and buttons (titles, time and
sometimes buttons).
Inactive Text - Color for inactive text and buttons.
Info Text - Color for misc. info (play mode)
Box Background Color - Color for box background (volume, track, order, about)
Main Color - Color for main screen background (main screen is the
screen containing all vital buttons and the main data
screen - It is what is left when all options are set
to "off").
Lighted sides - Color for lighted sides of buttons and frames. Swapping
it's value with that of "Dark sides" causes the 3d-look
to be reversed.
Dark sides - Color for dark (unlighted) sides of buttons and frames.
Border color - Color for border of buttons and frames. Every button and
frame is surrounded by a 1-pixel width line, which is
normally black.
NOTE - keeping button face and frame face at light-gray, and not changing dark
and lighted sides ensures that the 3d-look is maintained. All other
colors may be changed freely and satisfactory results can easily be
achieved. A sample of a chnaged-color cd-v is shown in screen.pcx.
Cdconfig.exe can be run with the command line option :
cdconfig -restore
Using this option restores cd-v.exe to the state it was after unzipping it
from cd-v##.zip (default BW look).
2.3. Track order selection
--------------------------
Press the Play-Mode button (drawn as 1-2-3 on diagonal) until ORD mode is
indicated in the main window, and the track order list should appear as well as
the track selection box (if it wasn't visible). The track list box will appear
a bit different in this mode - instead of the heading ("Tracks"), there will be
2 buttons which functionality will be explained below.
If this is the first time this mode is selection during a run of the
program, the list would be almost empty and the first entry whould appear as a
pressed button with the value of 1.
Selection of a track from the track list changes the number in the currently
pressed button in the order list and depresses the next slot on the order list.
A specific slot in the order list can be selected by the mouse, and it's track
number can be changed by the same way. Pressing the key '+' (or the key selected
in the config file, defaulted to '`'),or the button marked '+' at the top of the
track list, or the right mouse button when the cursor is positioned on the track
list box, will depress a new empty slot in the bottom of the order list, if
there is an empty one.
When choosing from the order list, you can always choose one of the tracks
previously selected or the next-to-last selected track. You can't choose a
specific button from the order list if there is an empty slot above it.
To erase the last entry to the list press the button marked '-' on the top
of the track list, or press the RIGHT mouse button when the mouse pointer is
positioned on any of the buttons of the order list. Keeping the button pressed
longer the 2 secs will activate the autorepeat feature which will erase an entry
every 0.2 secs as long as the button is pressed.
If your have a 3-BUTTON MOUSE, pressing the middle button while the cursor
is positioned on the track list box, will cause the slot above the currently
pressed to be active.
When leaving this mode, the track selection box will disappear if it wasn't
visible when you entered the mode, or remain visible if it was visible before
entering the mode.
Entering this mode another time will display the previously set list. The
mode is NOT functional, however, when the list is not DISPLAYED.
The about box will disappear and not return (unless pressed again) if it was
visible before entering the mode.
2.4. AutoRepeat
---------------
When pressing a button longer than 1Sec, it gets released and if still
pressed, will activate every 0.1Sec. Thus allowing true FF ,REW ,SKIP and PREV.
The volume control autorepeat is faster ; The delay is only 0.5Sec and then then
the button gets pressed every 0.01Sec (which is actually zero) and the volume is
changed by a larger amount (10 levels instead of one with single press).
Note that some buttons have other delay values (see above).

7. History

0.1 - First version.
0.2 - Fixed bugs :
1. Font and screen drivers not found when run from another directory.

indirectly (by ff, rewind, or track finish).
1.0 - Added Track order selection for playing and indication of play mode
at the top-right corner of the time display.
1.1 - Fixed bugs :
1. Memory access violations causing strange screen behaviour.
2. When clicking on a blank slot from the track list, a number appeared.
3. Incorrect disk length when playing entire disk.
1.2 - Fixed bugs :

conversion.
Added features:

appropriate driver), while positioned in the track list box, causes
the currently selected slot to ascend.
3. In ORD, Pressing the right button, while positioned in the track list
box, causes the currently selected slot to descend.
