how to write Null char in file... Chr(0) seems not to work :(

[torels]

Hello

Does anybody know how to write a null char [Chr(0)] to a file ?

I tried using Chr(0) but it desn't write anything... or it does but writes "" instead of (null)

Because Null = "". 'Null' is nothing, it's End of line.

Why would you want to write nothing to a file? Just curious.

OK... but if I write a script in vbs writing Chr(0) on a file and open it in scite I get the 'nul' rectangle and if I write it in autoit I get simply nothing... why ?

I want to write the zip header on a file... and it includes 18 'null's not 18 ""s & chr(5) & chr(6) & P & K

Then just try that.

It's What I did... But it doesn't work --> http://www.autoitscript.com/forum/index.ph...mp;#entry534471

I'ts only working on VBS

I think it's just the way autoit treats nul characters

You need to open the file in binary mode to write the null char:

$handle=FileOpen("hello.au3",17)
FileWrite($handle,Chr(0))

You need to open the file in binary mode to write the null char:

$handle=FileOpen("hello.au3",17)
FileWrite($handle,Chr(0))

Then you could probably open the file in normal mode allowing you to write other data, but I doubt it will work or is nessacary.

adding text in binary mode works

$hFile = FileOpen("test.tmp", 18)
FileWrite($hFile, "the quick brown fox " & Chr(0))
