C# Process Problem

ViperMAN

Hi guys,

I created a new Process in my C# program which calls a batch file which in turn runs a jar. This works fine until I want to redirect standard output and whenever I close the process, it kills the bat file but not the underlying jar.

After reading up I saw you could call the java.exe itself and pass in the jar as a parameter and it would fix my problems. The trouble with this is I get a "Access is denied" error on the line:

process.Start()

So, after further reading up I, I realised that I could use Impersonation to as the account I was using might not have permissions to execute the file. Firstly, I added the following line to see what was being logged in:

WindowsIdentity.GetCurrent().Name;

When debugging, it was filled with my windows authentication details, for instance; DOMAIN\\name. When I check the permissions of the the file java.exe my details are down as DOMAIN\name (note only one backslash) so I think that is stopping me from accessing the file.

Any ideas on how I can fix this or is there an easier way of getting around my original problem?

All ideas most welcome,
ViperMAN

cast to a string find the character "/" and strip out everything to the left of that.

Yes I thought of that too. Using the Impersonation LogonUser method but it returned invalid username or password.
