Just an interesting note: The VistaTools class you provide is almost verbatim the exact same that Intuit provides for their QB SDK examples/tools.

Rajkumar: Starting and stopping windows services can be done through a ServiceController (see sample code). If you don't have enough rights to access ServiceController, then you will want to run (or perhaps just restart!) your process elevated. That part is described here.

Thank you for sharing the code. Good work.
btw: You could use Resharper to clean up the code

Is there a way to elevate the process. I m always getting the second screenshot mentioned above that UAC is enabled but its not elevated.

Hey, I’m really interested in elevating my app from c#. Would it be too much of a hassle to publish that code, the c# wrapper and the dll?

Thanks

Thomas,

The code you reference is passing TokenElevationType as the value of TOKEN_INFORMATION_CLASS, whereas my IsElevated function is passing TokenElevation, which is meant to give a boolean result AIUI. I’ve also implemented GetElevationType which gets the Default/Full/Limited result.

Hi,

are you shure your function IsElevated is working correctly? I implemented the same function in Delphi 5 and “GetTokenInformation” always returned 0 running the prog as a not elevated administrator. Your c# implementation is doing exactly the same. I found this: http://groups.google.de/group/microsoft.public.dotnet.framework.interop/browse_thread/thread/63dadce5548b5bfe/931c034b5c7ee48b?lnk=st&q=+TokenElevationType+return+value&rnum=1#931c034b5c7ee48b and changed my Delphi code. Now my code returns TokenElevationTypeLimited for the case mentioned above. Starting my app as an Administartor I’m getting TokenElevationTypeFull. This seems to be correct. I think your function seems to work correctly because you are doing this:
return (te.TokenIsElevated != 0);

cheers
Thomas

Shouldn’t Vista remember the elevation for a particular app, something like “elevate always!”

You can set this for a shortcut – under Compatibiity – Privilege level.
