How to use GetProcess() for remote sytems

Greetings:

I have  a routine that determines whether a process is alive   Looks like this:

public bool IsProcessAlive(string hostname, string processName)
{
 Process p = GetProcess(hostname, processName);

 if (p == null)
 {
  return false;
 }
 else
 return !p.HasExited;
}

If I pass a system name which is not the local machine I get the error:

Feature is not supported for remote machines.  (NotSupportedException was unhandled)

What would be the work around for this?  Is there another function I should be using instead?

Thanks

Can you provide the source for your GetProcess method?

you might not have required permissions on the target machine to view the processes..........

also you can use..

dim p() As Process=System.Diagnostics.Process.GetProcessesByName(processname, hostname)

rob:

 public Process GetProcess(string hostname, string processName)
        {
            Process[] ps = Process.GetProcessesByName(processName, hostname);

            if (ps.Length == 0)
                return null;
            else
                return ps[0];
        }

nsanga,

Are you saying that 'GetProcessesByName()' has no restrictions regarding remote machines?  Since this is C# I'm guessing the statement should read:

Process=System.Diagnostics.Process.GetProcessesByName(processname, hostname)  // without the 'Dim p()'

What does 'p()' represent?

Now I understand - I'm already using 'GetProcessesByName()' :

Process[] ps = Process.GetProcessesByName(processName, hostname);

Hence, the problem is actually with the following line:

 return !p.HasExited;

This line is the one not supported for remote machines.  Any ideas how I can change this try/catch?

Thanks

Appreciate the link.  I just wish the person who posted that issue would have included a more detailed answer.  They end it like this:

>> using ConnectionOptions for authentication solved the problem.

I'm wondering just what this means.  The function used here only has two options:

GetProcessesByName(string ProcessName, string MachineName)
GetProcessesByName(string ProcessName)

What authentication options am I missing?

you have to use the second method to get the processes......

and regarding authentication......you have to use

System.Management.ConnectionOptions class.......( add reference to System.Management.dll )


please look at this link........this will give you an idea.....on how to use ConnectionOptions.authentication

Thanks for the reference.  My thoughts are:  If 'GetProcessesByName() is able to connect remotely but not able to use 'p.HasExited'  I'll just use another exit condition.  The small time elapsed from the successful connection to the call to 'p.HasExited' isn't worth worrying about.

I used the following:

public void IsProcessAlive(string hostname, string processName)
        {
            try
            {
                System.Diagnostics.Process p = GetProcess(hostname, processName);

                isProcessAlive_ = false;

                if (p != null)
                {
                    isProcessAlive_ = true;
                }
            }
            catch (Exception e)
            {
                if (e.Message.Equals("Couldn't connect to remote machine."))
                {
                    isServerAlive_ = false;
                }
            }
        }
