finally figured this out code is as follows for anyone interested... DiskQuotaControl dqcc = new DiskQuotaControl(); dqcc.Initialize(@"e:\" , true); foreach(DIDiskQuotaUser x in dqcc) { Console.WriteLine("Account Container Name {0}", x.AccountContainerName); Console.WriteLine("Account Status {0}", x.AccountStatus); Console.WriteLine("Display Name {0}", x.DisplayName); Console.WriteLine("ID {0}", x.ID); Console.WriteLine("Logon Name {0}", x.LogonName); Console.WriteLine("Quota Limit {0}", x.QuotaLimit); Console.WriteLine("Quota Limit Text {0}", x.QuotaLimitText); Console.WriteLine("Quota Threshold {0}", x.QuotaThreshold); Console.WriteLine("Quota Threshold Text {0}", x.QuotaThresholdText); Console.WriteLine("Quota Used {0}", x.QuotaUsed); Console.WriteLine("Quota Used Text {0}", x.QuotaUsedText); Console.WriteLine(); } this just iterates through all quotad users and prints the results to the console. Hope this help someone!

Hi zespri, The code works but throws up a unhandled win32 exception... The quota is implemented when you look... code is as follows: string userName = "Test User2"; string password = "abcdefg"; string quotaDriveLetter = @"C:\"; long quotaLimit = 52428800; //50MB long quotaWarning = 47185920; //45MB DiskQuotaControlClass dqcc = new DiskQuotaControlClass(); dqcc.Initialize(quotaDriveLetter , true); DIDiskQuotaUser dqnew = dqcc.AddUser(userName); dqnew.QuotaLimit = quotaLimit; dqnew.QuotaThreshold = quotaWarning; any ideas ? The host machine is XP Pro...

Try the following run tlbimp c:\windows\system32\dskquota.dll /out:c:\DskQuotaTypeLib.dll (change the path to *your* system32 directory) In Visual Studio project add c:\DskQuotaTypeLib.dll as areference Write a code similar to the following: using System; using DskQuotaTypeLib; namespace QuotaTest { class Class1 { [STAThread] static void Main(string[] args) { DIDiskQuotaControl quota = new DiskQuotaControlClass(); quota.Initialize(@"C:\",true); DIDiskQuotaUser user = quota.AddUser("Administrator"); user.QuotaLimit = 1024*1024*5; user.QuotaThreshold = -1; } } }
