Would anyone know how to edit the registry using a Messenger Plus! Live script? I can do it with Visual Basic .NET but it would help if someone told me how to write it in a script.

Thanks in advance.

var EnableOpt = Shell.RegRead(ValRegPath);
Debug.Trace("EnableOpt current value: " + EnableOpt);

I would read that Manual If I were you, lots of examples in it.

Thank you.

If by manual you mean scripting documentation, i'll do that.

That's what he meant

Tried to use this script but with a function to read & write.
Write works great, but reads gives an error.
If I try the Debug.Trace it works, but return doesn't.
(PS. Taken the script from another post, copied and it doesn't work).

code:

---

function ReadRegistry(key)
{
var Shell = new ActiveXObject("WScript.Shell");
return value = Shell.RegRead(MsgPlus.ScriptRegPath + key);
}

To analyze where the error is in such situations you should lookup what each object exactly will return in its documentation....

If you do that and you look up MsgPlus.ScriptRegPath in the scripting documentation (or you do simply a test with that object alone) you'll see that it returns a registry path.

Now you append the variable "key" to it, in other words you append a string to a path without anything else.... thus there is something missing in between... Think of it as a file and directory:

"C:\Program Files\MSN Messenger" would be the path and "msnmsgr.exe" the file, append the two and you'll get:
"C:\Program Files\MSN Messengermsnmsgr.exe" which is obviously something not correct as there is a "\" missing...


In other words:
    Shell.RegRead(MsgPlus.ScriptRegPath + "\\" + key);
note that you need to put a double "\" as it is otherwise interpreted as a literal escape code

So change that in your example and run it again....

The script will again not give the desired result. Why? Because you have other errors. The proper syntax for a "return" statement is:
    return <variable>;

and "value = Shell.RegRead(MsgPlus.ScriptRegPath + key)" is not a value but a statement on its own. So either you do:

    var value = Shell.RegRead(MsgPlus.ScriptRegPath + key);
    return value;

or simply:

    return Shell.RegRead(MsgPlus.ScriptRegPath + key);

From the Scripting Documentation
A string containing the path to the script's registry key. The path begins with "HKCU\" to designate the HKEY_CURRENT_USER key and ends with a backslash.

Sorry Cookie, but Plus gives you a Registry path ending with a backslash. If fixing the return statement doesn't fix it, I would imagine the error is because the variable key is not valid. Registry keys are case sensitive as awell, aren't they? Open regedit (via Start > Run) and check that the key you are looking for is actually there.

The Scripts Registry path is:
"HKEY_CURRENT_USER\Software\Patchou\Messenger Plus! Live\GlobalSettings\Scripts\"
Followed by the name of the script.

yeah, I noticed and was editing my post while you posted... Thanks for notifying though

Nope, they are case insensitive...

PS: note that the ActiveX registry object methods are rather limited though... to do more registry manipulation (or even writing binary data etc) you need to use the Windows APIs.

yeah, thought about the "return value = ..." thing...
I tried to play with it for over a hour and didn't succeed.
It works perfectly with Debug.Trace, so the problem is that it refuses to return the value.
Do I need to set the type of the return value or something?

BTW, tried to put it in value and "return value", tried just "return  Shell.Reg...", nothing works.

hmm, didn't tried to put it as a code in the orginal function and not in a separate function, but I use it too many times so it will be annoying and won't look nice...

Can't check it now, back to good old 7.5
Is it just me or WML doesn't seems so user-friendly (visually) like MSNM?

This is what I use for Screenshot Sender 4. If  you choose to keep the script you must keep the header regardless if you change the file or not.

This script is going to be apart of the snippets that will be available on http://mpscripts.net

For now its hosted on my server.

Note : If there are any errors with it please PM me. As well I am going to be changing the functions around a bit so I will update the file on my server and the latest one will be on http://mpscripts.net when we get enough snippets made.
