Does anyone know how to do the equivalent of this C# code in JScript?

Cheers,
- Mark

code:

---

try
{
        RegistryKey rootPath = Registry.CurrentUser.OpenSubKey("Software\\Item1\\Item2", true);
        foreach(string newKey in rootPath.GetSubKeyNames())
        {
                // other stuff here
        }
}

I think we had a thread about this a few weeks ago, but I can't find it anymore...

I think the solution was to use a win32 function for listing registry subkeys, because it seems like it cannot be done easily with the scripting engine.

Can somebody else find the thread / remember the solution?

No need for a DLL, it can be done without it

I have the code, but I'll have to look for it though
post them asap

-edit1- I found the code, but it is script specific, I will make it variable now
-edit2- Changed the code, gonna test it now...

-edit3- Here is the final code. The first function enumerates all available subkey names, the second function enumerates all key value names, could be used to look wich programs run on windows startup ("HKLM\Software\Microsoft\Windows\CurrentVersion\Run", if you'd want to know, user specific startup is located in HKCU instead of HKLM)

code:

function EnumSubKeys (RegKey) {
  var RootKey = new Object()
  RootKey["HKCR"] = RootKey["HKEY_CLASSES_ROOT"]   = 0x80000000;
  RootKey["HKCU"] = RootKey["HKEY_CURRENT_USER"]   = 0x80000001;
  RootKey["HKLM"] = RootKey["HKEY_LOCAL_MACHINE"]  = 0x80000002;
  RootKey["HKUS"] = RootKey["HKEY_USERS"]          = 0x80000003;
  RootKey["HKCC"] = RootKey["HKEY_CURRENT_CONFIG"] = 0x80000005;
  var RootVal = RootKey[RegKey.substr(0, RegKey.indexOf("\\"))]
  if (RootVal != undefined) {
    Locator = new ActiveXObject("WbemScripting.SWbemLocator");
    ServerConn = Locator.ConnectServer(null, "root\\default");
    Registry = ServerConn.Get("StdRegProv");
    Method = Registry.Methods_.Item("EnumKey");
    p_In = Method.InParameters.SpawnInstance_();
    p_In.hDefKey = RootVal;
    p_In.sSubKeyName = RegKey.substr(RegKey.indexOf("\\") + 1)
    p_Out = Registry.ExecMethod_(Method.Name, p_In);
    return p_Out.sNames.toArray();
  }
}

function EnumValues (RegKey) {
  var RootKey = new Object()
  RootKey["HKCR"] = RootKey["HKEY_CLASSES_ROOT"]   = 0x80000000;
  RootKey["HKCU"] = RootKey["HKEY_CURRENT_USER"]   = 0x80000001;
  RootKey["HKLM"] = RootKey["HKEY_LOCAL_MACHINE"]  = 0x80000002;
  RootKey["HKUS"] = RootKey["HKEY_USERS"]          = 0x80000003;
  RootKey["HKCC"] = RootKey["HKEY_CURRENT_CONFIG"] = 0x80000005;
  var RootVal = RootKey[RegKey.substr(0, RegKey.indexOf("\\"))]
  if (RootVal != undefined) {
    Locator = new ActiveXObject("WbemScripting.SWbemLocator");
    ServerConn = Locator.ConnectServer(null, "root\\default");
    Registry = ServerConn.Get("StdRegProv");
    Method = Registry.Methods_.Item("EnumValues");
    p_In = Method.InParameters.SpawnInstance_();
    p_In.hDefKey = RootVal;
    p_In.sSubKeyName = RegKey.substr(RegKey.indexOf("\\") + 1)
    p_Out = Registry.ExecMethod_(Method.Name, p_In);
    return p_Out.sNames.toArray();
  }
}

code:

var SubKeyArray = EnumSubKeys("HKEY_CURRENT_USER\\Software\\Item1\\Item2");
for (Index in SubKeyArray) {
   Debug.Trace(SubKeyArray[Index])
}

code:

---

var Shell = new ActiveXObject("WScript.Shell")
var Key = "HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Run"
var ValuesArray = EnumValues(Key);
Debug.Trace("=== Global startup ===")
for (Index in ValuesArray) {
   var ValueName = ValuesArray[Index]
   ValueValue = Shell.RegRead(Key + "\\" + ValueName)
   Debug.Trace(ValueName + " = " + ValueValue)
}
var Key = "HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Run"
var ValuesArray = EnumValues(Key);
Debug.Trace("=== User startup ===")
for (Index in ValuesArray) {
   var ValueName = ValuesArray[Index]
   ValueValue = Shell.RegRead(Key + "\\" + ValueName)
   Debug.Trace(ValueName + " = " + ValueValue)
}

new ActiveXObject("WbemScripting.SWbemLocator") ????
Locator.ConnectServer(null, "root\\default") ????
Registry.Methods_.Item("EnumValues") ????
etc...

I'm sorry but all this stuff is really not needed at all.

J-Thread is absolutely correct, 'simply' use the available Windows registry API's to do the job. They are all you need (although the method you showed has some "je-ne-sais-qua" too; still I really don't like the detour which activex takes (afterall, it uses those very same apis)).

Speaking of which, I have seen many registry accessing codes, and they are almost always exactly the same (with the same 'mistakes' or limitations), although they 'work', I haven't seen many totally fool proof and correct 100% codes (eg: first checking the length a registry key is, instead of assuming the key wnt be longer than x bytes, before retrieving it)

IIRC, Matty already posted an almost complete (but with some limitations) registry accessing script on the forums...
EDIT: I was wrong(partially) what Matty used was an external DLL => ActiveX Registry Access for Scripts

What do you mean "not needed at all", it does the job doesn't it?
He got his answer. It doesn't have to be from the API...

Personally, I always forget to 'Free' the Dll's I used, and a lot of scripts I looked at forget it too...
This way is a much cleaner way, because you don't have to use anything external, so it saves from using DataBloc structures (Interop.Allocate)

And by the way, these methods use an official Registry control object (StdRegProv)

Matter of opinion indeed...

I still think, using a class specificaly designed for Reg access is much easier, Most people don't create Windows with API calls either

(btw: I don't have access to the thread you showed... or something like that)

I havent yet looked at yours matty (I am now) but i made a registry class not that long ago to do this for someone on irc

http://svn.thedt.net/cgi/viewcvs.cgi/scripts/code...ass.js?view=markup

Matty: woopsy....
Matty, -dt-: nice, but misses a few things, and makes some of those common 'mistakes' (not really mistakes, but rather things which are't totally as it should be)

Thanks for the pointers guys, I found the WMI code on the web also. Does seem a bit overkill. Matty, your code looks like it will do the trick
