System.Diagnostics.Process Help

Ok I have been having the most trouble with the Process class. It keeps throw Access Is Denied for everything. I stumbled across this.

[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true, Synchronization = true,
ExternalProcessMgmt = true, SelfAffectingProcessMgmt = true)]
[PermissionSetAttribute(SecurityAction.LinkDemand, Name="FullTrust")]
[PermissionSetAttribute(SecurityAction.InheritanceDemand, Name = "FullTrust")]

Now I have no clue about this but I know your supposed to put above a func, constructor and all that. How can I just give my app all these permissions. Or better yet is there a better way to stop these rediculous exceptions. It happens on HasExited, Kill, Close, etc.

Where is the code being launched from and what does your code that uses the Process class look like.

Declaring

        AobotProc = new Process();
        AobotProc.StartInfo.FileName = AOPath + "//" + AOExe;
        AobotProc.StartInfo.Arguments = "-run -hide";
        AobotProc.StartInfo.WorkingDirectory = AOPath;
        AobotProc.EnableRaisingEvents = true;
        AobotProc.Start();
        AobotProc.Exited += new EventHandler(aobot\_proc\_Exited);

and errors wen

        if (AobotProc != null && !AobotProc.HasExited)
        {
            if (!AobotProc.CloseMainWindow())
                AobotProc.Kill();
        }

errors at AobotProc.HasExited saying Access Is Denied

What version of the .NET Framework are you using?? Is this code running under Vista??

.Net 3.5 and yes on Vista

Dave Kreskowiak

The Process class uses the system performance counters, which on Vista, requires an Admin level account to use. You really have no choice but to include a manifest with your app that tells Vista that the app will require an administor account to run. First, watch the video here[^]. Then you can read this[^].
