limiting number of instances in Windows terminal server

[Dalai]

Yes, reading the number of processes running as user X is another possible approach. Unfortunately I don't know how to read the user a process runs as, even less when TS is involved.

Hello,
use a GUID as (global) Mutex-Name with _1, _2 and so on.

if _1 is used, use _2.
if _x is used, you have your maximum instances ...

quick&dirty


or just said: use JEDI JvAppInst.pas
hey use some form of hidden window for each instance

It is easy to count the instances running in the current session. Example in .Net:

Code:

private static int CountApplicationInstances()
    {
        var currentProcess = Process.GetCurrentProcess();
        var processes = Process.GetProcessesByName(currentProcess.ProcessName);

        // test if there's another process running in current session.
        var intTotalRunningInCurrentSession = processes.Count(prc => prc.SessionId == currentProcess.SessionId);

        return intTotalRunningInCurrentSession;
    }
