how to disable ctrl-break

[Guest_imported]

i need to disable the ctrl-break interupt because i am trying to make a password program to run in DOS.

See the "Blinking Cursor" example on this page. CTRL+Break will stop a QB program while it is polling for keystrokes in the QB IDE, but it has no effect after the program is compiled.

This is in contrast to using an INPUT statement, where CTRL+Break will interrupt your program, regardless.

Try it.

Alt255:

Here's a slightly modified code, although it will produce a control(ED) break at the END of the program. It may be of use to someone.

[tt]CLS
Password$ = ""
LOCATE 12, 2: PRINT "Enter Password: "
DO
LOCATE 12, 18 + LEN(Password$), 1, 8, 9
I$ = INPUT$(1)
'I$ = INKEY$
IF I$ = CHR$(0) + "m" THEN
SLEEP 1
END IF
IF I$ = CHR$(13) THEN EXIT DO
IF I$ <> &quot;&quot; THEN PRINT &quot;*&quot;;
Password$ = Password$ + I$
LOOP
PRINT
PRINT
PRINT &quot;word=&quot;, Password$[/tt]

As you can see, I've only added two more lines and REM'd out one. Of course it may need to be touched up a bit for different apps. But it should work.
