Disk Quotas in C#

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!

The code seems to work find on 200 server machines... Also... Any ideas on how to enumarate all users and there quotas? Thanks in advance for your help

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...

cheers, i will give that a go. dskquota.dll is a com object isnt it? Is there not a way to do it in the .net framework...

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; } } }
