C# Code works under win2000 but not XP

[Loug52]

Hi, all. I am working on a C# code that can retrieve system log by using WMI. However, the code is working fine under windows 2000, but got error messages under Windows XP. The erro message is : Unhandled Exception: System.Management.ManagementException:Access denied. at System.Management.Management.Exception.ThrowWithExtendedInfo(ManagementStatus errorCode) at System.Management.ManagementEventWatcher.Start() Part of my code is like following and I believe this is where the problem at: ---------------------------------------------------------------- public static ManagementEventWatcher getWatcher(string comp, string LogName) { ConnectionOptions co; ManagementPath mp; ManagementScope ms; WqlEventQuery EventQuery; ManagementEventWatcher watcher; string wql; string wqlAnd; co = new ConnectionOptions(); co.Timeout = new TimeSpan(0, 0, 60); co.EnablePrivileges = true; mp = new ManagementPath(); mp.NamespacePath = @"\root\cimv2"; mp.Server = comp; // comp is the computer you are connecting to ms = new ManagementScope(mp, co); Console.WriteLine("host is" + comp +"Logname is "+LogName); switch(LogName.ToUpper()) { case "ALL": wqlAnd = ""; break; case "SECURITY": wqlAnd = " AND TargetInstance.Logfile ='Security'"; break; case "SYSTEM": wqlAnd = " AND TargetInstance.Logfile ='System'"; break; case "APPLICATION": wqlAnd = " AND TargetInstance.Logfile ='Application'"; break; default: wqlAnd = ""; break;

Thanks for replying. the code is running under admin privileges.

Is this code running with full trust on both machines? According to the docs, ManagementEventWatcher.Start requires full trust to run, so if you're running it across your network with the default code access security settings, it won't work. Charlie if(!curlies){ return; }

Ever hear to try/catch blocks Ex:

public void Example()
{
try
{
//Your Executable code here
}
catch(Exceptopn){} //Catches all Excetions
catch(Excetion e) //Catches all Exceptions also
{
//What do you want to do when an excetion has happend
Console.WriteLine(e.ToString()); //Helps to Debug and find
//the specific Excetion
}
/*
finaly
{
//Code that will always Execute even with Excetion or not
//The finaly block is optional and is not needed
}
*/
}

One part of my progs #region Constructor private Game(Control cTarget) {   try   {     this.target = cTarget;     this.target.GotFocus += new System.EventHandler(this.Restore);     this.graphics = new GraphicsHandler(this.target);     this.sounds   = new SoundHandler(this.target);     this.keyboard = new InputHandler(this.target);     this.presentState    = new GameState();     this.previousState   = new GameState();     this.presentData     = new GameData();     this.presentDataTemp = this.presentData.DeSerialize();     this.physics = new GamePhysics();     this.InitGame();     Timer.Init();   }   catch(Exception e)   {     MessageBox.Show("ERROR WHILE INITIALIZING GAME " + e.ToString());     return;   }   this.presentState  = GameState.Initialized;   this.previousState = GameState.Initialized;   this.GameLoop(); } #endregion cdmlb

To add to what Charlie said, and he's got the most likely answer to your problem, ... He, and I, are both assuming that your running your application from a network share. Even though your logged in under an admin account, the .NET Framework will not give your application Full Trust to run. Read up on Code Access Security here[^].
