Interrupt 21/43 problem with NT/Windows 2000

[ADAM HARKUS]

We are having a problem setting the archive/share file attributes
using interrupt 21function 43 on NT/Windows2000 workstations
using a Novell Netware server. It is working ok on workstations
running Windows 95/98 but not on NT/Windows2000.

On NT/Windows 2000 workstations it will not flag the file for
share if the archive attribute is already set on, it actually
sets the share attribute off. If archive is not set then the
archive/share attributes are set but only if the file status is
not ‘co’ compressed.

The code we are using is as follows:

FUNCTION MKSHARED%(stringptr$) PUBLIC
stringptr$=stringptr$ + CHR$(0) ‘File name to flag.

AX%=&H4301 ‘Function 43, Set attribute (01).
BX%=&H0000
CX%=&H00A0 ‘10100000 Binary = A0 hex.
DX%=STRPTR(stringptr$)
DS%=STRSEG(stringptr$)

REG 1, AX%
REG 2, BX%
REG 3, CX%
REG 4, DX%
REG 8, DS%

CALL INTERRUPT &H21

AX% = REG(1)

IF AX% = &H4301 THEN
MKSHARED% = 0
ELSE
MKSHARED% = AX%
END IF

END FUNCTION

I have made a mod to the code to get the attributes instead of
setting them and get different results for each operation system
when the share attribute is the only one set. Windows 95/98
returned 128 (10000000 / 80h) and NT/Windows 2000 returned 0?

It just looks like NT/Windows 2000 does not support the share attribute correctly.

Time was, a "normal" file had an attribute of zero. Oddly enough, Microsoft
changed the "normal" attribute to &H80 in 32-bit Windows. This conflicts
directly with Novell's longtime use of the same attribute to mean "share".

Thanks Tom for that explanation.
I have been looking high & low for a reason why it didn’t work!

My next question is obvious, does anyone know of a solution.

One possibility is to use Novell's "FLAG.EXE".

SHELL "FLAG MyProgram +Sh"
