v3.2.12.0 + RegRead (REG_MULTI_SZ)

[Stéphane]

if you try to read a REG_MULTI_SZ realy big key > 255 chars, RegRead returns nothing and @error is set to -2, smaller keys are read correctly

[J-Paul Mesnage]

can you give an example using an existing key in the registry?
Thanks

[J-Paul Mesnage]

$keyname = "HKCU\Test"
$value="1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890" & @LF
$value&="1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890"

$RegWrite = RegWrite($keyname,"RegMultiSz","REG_MULTI_SZ",$value)
$RegRead = RegRead($keyname,"RegMultiSz")
MsgBox(262144,'Debug line ~' & @ScriptLineNumber,'Selection:' & @lf & '$RegRead' & @lf & @lf & 'Return:' & @lf & $RegRead & @lf & @lf & '@Error:' & @lf & @Error) ;### Debug MSGBOX
$RegDelete = RegDelete($keyname)

That's working perfect under Vista SP1. So you understand that" you need to follow directive as how to write a bug ticket

I think we limit reg operations to 64KB. Might be worth rewriting/checking if this is the case.

Replying to Jon:

So that's nothing to do with a 255 char limit ...

Your report is confusing. Here's what I can say.

If you really do mean "key", then yes, a limit of 255 is correct. Each key name can only be 255 characters. The full path can be longer than 255 characters but any one individual key name can only be 255 characters. This does not appear to be a bug, although I can't find mention in a quick scan of MSDN.

If you mean the size of the data a value can hold, then it's definitely not limited at 255. Since you mention REG_MULTI_SZ, you may be experiencing an issue with an improperly formatted data. This would not be an AutoIt bug, either.

Without a proper script to reproduce the issue and without clarification of the terminology which is rather critical, there's nothing to do but close this as works for me. I tried a few things and could not reproduce what you describe.

[Valik]

Alright, I found the registry size limits which confirm what I said:
