Hi all,
I want to know if is possible to write directly on disk with visual basic(Not
in a file), i know with
interrupt DOS, it's possible. And if is possible to write any line of code
ASM in visual basic.
Thanks all

On Windows 9x, you can probably do this using DeviceIoControl and the
VWIN32 virtual device driver. Check out

Hi Mark --
Do you have reason to suspect that DeviceIoControl is *not* callable from VB?

Karl,
It certainly *is* callable -- remember that little ditty I did recently for
Ask The NT Pro on NT file compression?
(http://www.inquiry.com/techtips/nt_pro/10_minute_solutions/10min0900.asp).
Only hard part was the one of the "constants" was actually an ugly little C
macro. Other than that, duck soup...

What about calling DeviceIoControl from Win9x via the VWIN32 VxD interface...
I can't seem to get that to work for VWIN32_DIOC_DOS_INT25
Can anybody point me in the right direction?
