By default administrators did not have full access to system keys. See the MSDN article Registry Key Security and Access Rights[^] about accessing system keys.

Thankyou Covean, With this approach i implemented and is working. The Link http://www.codeproject.com/KB/dotnet/WindowsServices.aspx is helpful. Thanks, Prasad

In your example code I miss the SetTokenInformation part. Thats all I can say at the first look. I also received your e-Mail and I will answer if I have the time for (I hope this will be tommorrow   :) ). Greetings Covean

Marshaling char** parameters isn't easy, and probably not worthwhile. I would recommend any of three alternatives: 1. implement the functionality directly in C# 2. call an existing native function of a lower level, e.g. dealing with just one device at a time (pass a StringBuilder to be filled) 3. pass a StringBuilder instance with sufficient capacity, and store the device names in there, separated by some character, say a semi-colon; upon return call ToString() and Split(';') on it. :) Luc Pattyn I only read code that is properly indented, and rendered in a non-proportional font; hint: use PRE tags in forum messages Local announcement (Antwerp region): Lange Wapper?

Well, there and already thousands(or probably more) examples of this on internet. Did you try even once to look for something very simple like this[^]? Manas Bhardwaj Please remember to rate helpful or unhelpful answers, it lets us and people reading the forums know if our answers are any good.

Try using SAFEARRAYs rather than standard C arrays. That way, there should be metadata in the type library or something that can help the process. This CP article[^] might help :-) Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

If you don't mind could you please provide me the code snippet for the above.
