Reading the registry from ScriptExtensions

Hi Howie,



One note about the .NET method: by default, it accesses only the 32-bit or only 64-bit registry - as specified by the Preferred architecture of the assembly hosting process option in the CLR Bridge options of the current project. If you need to access both 32-bit and 64-bit registries at the same time (e.g. in HKLM\SOFTWARE\ and HKLM \SOFTWARE\Wow6432Node), use something like this:

(Note: This requires .NET Framework 4+.)

function Test()

{

  var HKLM = -2147483646;

  var key = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion";

  var value = "ProgramFilesDir";



  var str = GetRegistryValue(HKLM, key, value /* , 32 */);

  Log.Message(str); // C:\Program Files (x86) - value from Wow6432Node



  str = GetRegistryValue(HKLM, key, value, 64);

  Log.Message(str); // C:\Program Files

}



function GetRegistryValue(RootKey, KeyName, ValueName, Bitness)

{

  var oRegView = (Bitness == 64

    ? dotNET.Microsoft_Win32.RegistryView.Registry64

    : dotNET.Microsoft_Win32.RegistryView.Registry32);



  var oRoot = dotNET.Microsoft_Win32.RegistryKey.OpenBaseKey(RootKey, oRegView);

  var oKey = oRoot.OpenSubKey(KeyName);

  return oKey.GetValue(ValueName);

}
