Since I haven't heard anything from my origianl posting, let me make my
question simpler. Is there any way to make QB (version 4.5) program
think as if shift-printscreen is pressed (so that DOS's TSR, GRAPHICS,
print the VGA graphics)?

Any comments/suggestions are welcome and will be greatly appreciated.
Please help.

Do U know any assembler ?
No ?  
Do  U know DEBUG ?
---------------------
DEBUG PS.COM
A
INT 5
INT 20
RCX
3
W
Q
----------------------

IN BASIC:
.
.
.
SHELL"PS.COM"
----------------------

What DEBUG does, is poduce a 3byte machine language .com file, to print
the screen (using interrupt 5).
---------------------------------------

(
Acually I used a simpler  trick, : -

1- define a  single-precision  GWBAISC floating number  (actually that
number= the 3byte above-mentioned com file, plus a pad byte)

2- use the call statement, to call that number.

No SHELLing needed.
)

-------------------------------------------------------

As 4 every time of the day

U either write it in BASIC, using the time$ function & an edless loop
(U would have 2 SHELL to a DOS  complex batch file that uses the DS
date command, & that gets messy)

or

down load a ready-made  shareware that  runs  a program  every certain
time/date.

U can  even  write it  thyself, if   thou art  versed  in  the  arcane
mysteries of batch files (esp errorlevel).

Email me I U need more help, or just 2 let me know how U r doin.

       Yea, it's interrupt #5 that called the printscrn function.

' INCLUDE: 'QB.BI'
' Print the screen
DIM Regs AS RegType
Interrupt &H05, Regs, Regs
END

*NOTE: you have to include the QB.BI for this to work.

I guess the easyest way to do that would be to call the "print screen"
interrupt.  This is INT 05h.  This is the interrupt that is called when
you hit the "print scrn" button on your keyboard.  If you want to program
the printer yourself, look in the HP deskjet manual and see what the
codes are to send to the printer.  After programming the printer then
just send the data to be printed.

To use this, you must start QuickBasic with the /lQB option, to make the
CALL ABSOLUTE function availiable (it lives in the QB.QLB and QB.LIB files)

Hope that helps,
