Question

We have an issue with the way we are creating a Mutex. The problem line is:

MutexAccessRule rule = new MutexAccessRule('Everyone', MutexRights.FullControl, AccessControlType.Allow); 

The hardcoded ‘Everyone’ string only works on English OSes, how do we change this line so it works in all languages?

This code solves this problem:

  SecurityIdentifier sid = new SecurityIdentifier(WellKnownSidType.WorldSid, null);   MutexAccessRule rule = new MutexAccessRule(sid, MutexRights.FullControl, AccessControlType.Allow); 

VB:

Dim sid As System.Security.Principal.SecurityIdentifier = New System.Security.Principal.SecurityIdentifier(System.Security.Principal.WellKnownSidType.WorldSid, Nothing) Dim rule As System.Security.AccessControl.MutexAccessRule = New System.Security.AccessControl.MutexAccessRule(sid, System.Security.AccessControl.MutexRights.FullControl, System.Security.AccessControl.AccessControlType.Allow)
