Array size

[OmYcroN]

Hi. I'm using IniReadSection() to read some data and i have 440 values in the ini file. The returning array shows me only 435. What it's happening? It's the max size for the returning array ?

Only the first 32767 chars are taken in account in an section due to Win9x compatibility.

Is that it? How big is the file? if its smaller than 30kb then ignore me.

And if i want to "brake" that compatibility ?

[Mat]

umm...

Split up the file into seperate sections, 2 sections of 200 should do. I you don't want to do that then...

Write your own function! Shouldn't be too hard:

For $i = 1 to FileGetLines ($sIni)
If StringLeft (FileReadLine ($i), 1) = "[" Then; is key
    $Start = $i
    ExitLoop
EndIf
Next
If $Start = "" Then Return SetError (1, 0, 0)
For $i = $Start + 1 To FileGetLines ($sIni)
If StringLeft (FileReadLine ($i), 1) = "[" Then; is key
    $End = $i
    ExitLoop
EndIf
Next
If $End = "" Then $End =  FileGetLines ($sIni)
For $i = $Start + 1 To $End - 1
$Line = Filereadline ($i)
$Split = StringSplit ($line, "=")
If $Split[0] <> 2 then Return SetError (1, 0, 0)
;;;;
Next

basic code, and untested, but you get the idea.

The problem is that AutoIt currently uses the Windows API for reading INI files. Windows has that limitation.

So it's 32767 chars per section ? Or per file ?

[Richard Robertson]

Per file.

I don't know, I just happened to be doing this today (messing around with ini's) and I saw the limit. When you posted, I replied with an answer. I am presuming its section though, try it, if it works then it works! There you go then!

@Rich

Do you have a link to the page where it gives the commands? I can only find stuff on fmapi's, which is not right.

I see ... Thanks for this info.

[Richard Robertson]

Do you mean the native INI reading? I can look.

[Mat]

yup, I've searched msdn, but found little. I was probably looking in the wrong place as usual...

I understand that inireadsection() reads a max of 32767 chars.

So i use n sections for n * 32767 chars. Right ?

quote Richard = "per file"

This function, GetPrivateProfileString, is probably it. I assume that since it hasn't been rewritten to avoid this limit, that it still uses this.

It doesn't say anything about the limit other than saying that it was kept for 16 bit app compatibility. 16 bit addresses could only address 65535 locations, and half of that minus one is 32767 (two's compliment). That's my guess..?

You could be a little more economical with the variable names to stay under the character limit, or get rid of comments/spaces/unused stuff. If it's your ini of course :-D

[Mat]

Thanks rich!

That looks like its right.
