Hi All,

I was wondering if you could help me

Besically I'm reading in a file

it contains a 4-char ASCII field with a number "8   "......

I want to convert that 8 in ASCII to an AutoIt variable so I can do other tests

So far I've got

$IDcomputer = FileRead($file, 4)
MsgBox(4096,$sAppName,"i can confirm IDcomputer is " & $IDcomputer)

which outputs 

     "I can confirm IDcomputer is 0x38202020"

what am I supposed to make AutoIt take this 4-byte char field as such instead of this integer 0x38202020?

Thanks in advance!

:)

Pablo.

Pablos544,

Use BinaryToString on the value read from the file:

#include <MsgBoxConstants.au3>

$sValue = "0x38202020"

$iValue = BinaryToString($sValue)

MsgBox($MB_SYSTEMMODAL, "Result", $iValue)

Pablos544,

Those functions are not often needed - but they are very handy when they are!

But when you reply in future, please use the "Reply to this topic" button at the top of the thread or the "Reply to this topic" editor at the bottom rather than the "Quote" button - I know what I wrote and it just pads the thread unnecessarily.

Ok it was not clear to me how to reply without quoting!!  I agree it adds noise to the topic and ideally what you want is to see the discussion.  I did not really want to quote your comment of course you knew what it was.  But of course from now on I will reply straight out that is no problem.  Thanks for the help.

Hi Melba23,

And may I take this opportunity to wish you and your family a lovely Easter Weekend.

I am really thankful for all the help I've received in this forum.  Specially this

Binary Variant / FileRead

I still can't work out AutoIt's use of Binary Variant instead of string.

If you hand't helped me I think I'd have been finished there :sweating:

Cheers,

Pablo.
