Re: Editing the nth byte of a BINARY Registry Value

Hi!

Example:

I need change binary value (one byte "0a" to "03" ) in key

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]

"DaylightStart"=hex:00,00,0a,00,05,00,03,00,00,00,00,00,00,00,00,00

to the new value.

Script:

****************************************************************************************
const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."

Set objReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" _
   & strComputer & "\root\default:StdRegProv")

'Define byte's array
Dim bArray

strKeyPath = "SYSTEM\CurrentControlSet\Control\TimeZoneInformation"

'Fill array with values of the key;
'array elemnts starts from 0  an up,
'so I need to change bArray(2) element's value

objReg.GetBinaryValue HKEY_LOCAL_MACHINE, strKeyPath, "DaylightStart", bArray

'Changing value
bArray(2) = 3

'Write infromation back
objReg.SetBinaryValue HKEY_LOCAL_MACHINE, strKeyPath, "DaylightStart", bArray

Set objReg = Nothing

Hello

I'm trying to edit a Binary Registry value which I can do by doing a full replace of the data, but because the data could be different from machine to machine and only specific bytes change I was trying to write a script that would allow me just edit specific bytes for example byte 6 and 63, but I don't know the best way to go about it.

Could I use to the Replace function in this example?
Replace(reg_string, "00", "01", 63, 1, 0)

If so would someone be able be able to help me read in a binary registry value that I could run the replace on.

I really don't have any preference how I get to how I get this to work, my programming knowledge is limited so any advice or help would be most appreciated.

Thanks for time

PS My reference to a byte is if you export out from the registery a binary value eg "1"=hex:03,00,00,00,00,00,00,

I'm asuming that the number inbetween the coma's represets a byte and I've worked out byte's that I would need to change.

Please feel free to tell me if i'm being a doughnut
