Problem with _WinAPI_RegSetValue

[avechuche]

Hi, I'm trying to modify a key "REG_NONE" but I had no luck. 

If I use this code, it does not change anything.

#include <WinAPIReg.au3>
#include <String.au3>

Local $sString = "Some value"
Local $iBytes = 0

Local $hKey = _WinAPI_RegOpenKey($HKEY_CURRENT_USER , "Software\DownloadManager")

; LocalPathW have HEX value

_WinAPI_RegSetValue($hKey, "LocalPathW", $REG_NONE, _StringToHex($sString), $iBytes)

_WinAPI_RegCloseKey($hKey)

 But if $iBytes = 0, the record is changed, the value is deleted, but the value I want is not entered.

Did you do any error checking to see where it's failing?

No mistake of any kind.

$iBytes has to be the length of the data you're adding to the key in bytes, setting it to zero means add nothing and delete what's there.

Try

_WinAPI_RegSetValue($hKey, "LocalPathW", $REG_NONE, _StringToHex($sString), StringLen($sString))

I know, but the only way I modified the value is if I add a 0. Any other value does not change the record.

I tried this but it does not work

_WinAPI_RegSetValue($hKey, "LocalPathW", $REG_NONE, _StringToHex($sString), StringLen($sString))

_WinAPI_RegSetValue($hKey, "LocalPathW", $REG_NONE, _StringToHex($sString), StringLen(_StringToHex($sString)))

For a REG_NONE key, it seems that they're all zero-length binary value in the registry, at least all the ones that I was able to find. From further researching this, the value of a REG_NONE key isn't important, so you can put anything there and it will be ignored.
