Installation 45
If you will be connecting and disconnecting your mouse you can place MOUSE
and NOMOUSE in your AUTOEXEC file. NOMOUSE will not load if it sees a
mouse driver. A trick to prevent the warning message output by NOMOUSE is
shown in the following example:
MOUSE ; mouse driver
IF ERRORLEVEL 0 GOTO :OK ; if loaded OK, skip NOMOUSE
C:\TOUCH\NOMOUSE ; load NOMOUSE if no MOUSE
:OK
C:\TOUCH\ELODEV 2201,280,5 -C722,3587,3319,841,1,15
; touchscreen driver
C:\TOUCH\MONMOUSE -M6 ; MonitorMouse for DOS
Using MonitorMouse Without a Mouse
MonitorMouse for DOS requires a mouse driver to supplement some of its
functions. Therefore, MONMOUSE.COM will not load unless it detects a loaded
mouse driver. However, most mouse drivers will not load unless they detect a
mouse.
There are two ways to load a mouse driver without a mouse connected.
Using NOMOUSE.COM
If a DOS mouse driver was not detected by the INSTALL program,
NOMOUSE.COM was placed in your AUTOEXEC.BAT file. NOMOUSE.COM
is a TSR program. It occupies only about 600 bytes of system RAM when loaded,
as opposed to over 16K for most current mouse drivers, and does not affect the
use of any serial ports or hardware interrupts.
NOMOUSE.COM does not contain code to display a mouse cursor. However, a
cursor will still be displayed in Windows and when running DOS programs that
draw their own cursor. With most dedicated touchscreen applications, a cursor is
not required anyway. In fact, a cursor may distract the user because their eyes will
be drawn to the cursor instead of focusing on the entire image.
NOTE
MonitorMouse for DOS will only be active while mouse-driven applications are
running. Therefore, MonitorMouse for DOS will not conflict with touchscreen
applications that do not use it. Because MonitorMouse for DOS takes over
ELODEV when it becomes active, a single program should not make both mouse
and ELODEV or TouchBack calls.
If you have both MonitorMouse for DOS and TouchBack loaded, TouchBack
applications should call the ENABLE command at start-up, and DISABLE before
exiting. MonitorMouse for DOS or TouchBack may also be extracted from
memory when not in use.
