So I am trying to write a script that can take the current computer name and write it to a registry key.

This key uses REG_BINARY type of key and looks like this:

Value 1
  Name:            LocalName
  Type:            REG_BINARY
  Data:            
00000000   54 4f 55 47 48 42 4f 4f - 4b 36 30 39 38 00 00 00  TOUGHBOOK6098...
00000010   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
00000020   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
00000030   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
00000040   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
00000050   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
00000060   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
00000070   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
00000080   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
00000090   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
000000a0   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
000000b0   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
000000c0   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
000000d0   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
000000e0   00 00 00 00 00 00 00 00 - 00 00 00 00 00 00 00 00  ................
000000f0   00 00 00 00 00 00 00 00 -                          ........

Its apparently very important that all the ending 00's are in there I found this out as I was working on some other keys that had to do with security settings, and if the key was say 01 00 00 putting any less or any extra ending zeros would cause the change in the regsitry to not effect the software.

So what I am attempting to do is use the @ComputerName macro and plug it into a StringtoBinary() function and then write it to the registry.

The challenge I face is how to fill in the entire binary value for the registry key and not just the converted strings value.

I wonder if there is some easy code to do that.  I imagine there must be a few ways but I am looking for the most straight forward/easiest. 

Also on a side note, instead of using RegWrite is there a way to create a .REG file that I can call from CMD with Reg Import?

This is being done at an enterprise level and the users do not have access to write to the registry, but they can import a reg file via .bat or in my case a Autoit .exe with @ComSpec

Currently I am importing all the "static" keys I need for configuration, but computer name is dynamic so that is why I am trying to find a way to use the @ComputerName macro to insert that value.

Regards,

Another method: 

ConsoleWrite(StringToBinaryFixed(@ComputerName, 16) & @CRLF)

Func StringToBinaryFixed($sString, $iLength)
    Local $tChar = DllStructCreate("CHAR[" & $iLength & "]")
    Local $tByte = DllStructCreate("BYTE[" & $iLength & "]", DllStructGetPtr($tChar))

    DllStructSetData($tChar, 1, $sString)

    Return DllStructGetData($tByte, 1)
EndFunc

Managed to come up with my own solution, very crude but very simple :)

I am sure it can be tightened up to be cleaner and still use this same technique

This wont help me get past the fact normal users do not have admin access to the registry so I will have to see if there is a way to make a .REG file out of my result and also still further yet need a simple check to see if the machine in 32bit or 64bit since they use different HKLM directories for software.

Looking forward to see what you guys can add.

Not sure this is what you're after but...

#include <FileConstants.au3>

Global $g_dData = StringToBinaryFixed(@ComputerName, 247)

$g_dData = StringTrimLeft($g_dData, 2)
$g_dData = StringRegExpReplace($g_dData, "[0-9A-F]{2}", "\0,")
$g_dData = StringTrimRight($g_dData, 1)
$g_dData = StringLower($g_dData)

Global $g_sHive

If (@OSArch == "X86") Then
    $g_sHive = "HKEY_LOCAL_MACHINE\SOFTWARE\Toshiba"
Else
    $g_sHive = "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Toshiba"
EndIf

Global $g_sValue = "Test"

Global $g_sFileText = StringFormat('Windows Registry Editor Version 5.00\n\n[%s]\n"%s"=hex:%s', $g_sHive, $g_sValue, $g_dData)

Global $g_hFile = FileOpen(@DesktopDir & "\RegKey.reg", $FO_OVERWRITE + $FO_CREATEPATH) ;~ Create .reg file on desktop.
FileWrite($g_hFile, $g_sFileText)
FileClose($g_hFile)

Func StringToBinaryFixed($sString, $iLength)
    Local $tChar = DllStructCreate("CHAR[" & $iLength & "]")
    Local $tByte = DllStructCreate("BYTE[" & $iLength & "]", DllStructGetPtr($tChar))

    DllStructSetData($tChar, 1, $sString)

    Return DllStructGetData($tByte, 1)
EndFunc
