EventLog counting users - c#

Good day, I've been fiddling around with the Eventlog method, and with fiddling around I was able to count how many entry.replacementstrings[5] aka usernames would be there.
public int countUsers { get; set; }
public string User { get; set; }
public Users(int count, string name)
{
countUsers = count;
User = name;
}
public void getCountUsers()
{
number = 0; //
UserList = new ObservableCollection<Users>();
EventLog myNewLog = new EventLog();
myNewLog.Log = "Security";
foreach (EventLogEntry entry in myNewLog.Entries)
{
if (entry.InstanceId == 4624 && entry.TimeWritten.Date == DateTime.Today)
{
if (UserList.Count > 0)
{
bool check = false;
foreach (var user in UserList)
{
if (user.User == entry.ReplacementStrings[5])
{
user.countUsers += 1;
check = true;
}
}
if (!check)
{
Users u = new Users(1, entry.ReplacementStrings[5]);
UserList.Add(u);
}
}
else
{
Users u = new Users(1, entry.ReplacementStrings[5]);
UserList = new ObservableCollection<Users>();
UserList.Add(u);
}
}
}
}
public void counter()
{
var totalUsers = UserList.Sum(user => user.countUsers);
foreach (var user in UserList)
{
Console.WriteLine("There has been {0} users on {1}", user.countUsers, DateTime.Today.ToShortDateString());
}
}
Is what I currently have. What I now want to be able to do is, add a regex to the writeline so it doesn't count the user SYSTEM.
I was able to do it with but that would print out every individual user, but instead I want the general/global idea of how many people were online at said date.
So I need to know how to do it with getting rid of the for each loop, and just getting the user.countUsers.
foreach (var user in UserList)
{
Regex User = new Regex(#"SYSTEM");
Match match = User.Match(user.User);
if (!match.Success)
{}
}
I now don't know how to call the variable so my regex works. Anyone know how to fix it, maybe possibly without a regex?
(Side note: I also need help with the fact that the EventLog is 2x, when it should be 1 by the ones that are legit. I would need to see how I would filter that)

You don't need to use Regex since the string you want to exclude is literal, you can use Linq:
foreach (var user in UserList.Where(u => u.User != "SYSTEM"))
{
Console.WriteLine("There has been {0} users on {1}", user.countUsers, DateTime.Today.ToShortDateString());
}

CRM Dynamics 2013 SDK Update Current Accounts With 2 Values

I have a scenario in CRM where I need to update existing accounts with their Vat and Registration number. There is well over 30 thousand accounts in the system. I am trying to update using the CRM SDK API but I am battling to figure out how to perform the actual update. The vat number and reg have been provided to me in a spreadsheet with their corresponding number, please note that the accounts are already in CRM so I just need to update the correct account with its Vat and Reg number, How can I do this in CRM, please advice on my code below:
public static void UpdateAllCRMAccountsWithVATAndRegistrationNumber(IOrganizationService service)
{
QueryExpression qe = new QueryExpression();
qe.EntityName = "account";
qe.ColumnSet = new ColumnSet("account", "new_vatno", "new_registrationnumber");
qe.Criteria.AddCondition("accountnumber", ConditionOperator.In,"TA10024846", "TA10028471", "TA20014015", "TA4011652", "TA4011557");
EntityCollection response = service.RetrieveMultiple(qe);
foreach (var acc in response.Entities)
{
acc.Attributes["new_vatno"] = //this is where I am struggling to figure out how I am gong to match the records up,
acc.Attributes["new_registrationnumber"] = //this is where I am struggling to figure out how I am gong to match the records up,
service.Update(acc);
}
}
How am I going to ensure that I update the correct records. I have the vat and reg numbers for the accounts in a spreadsheet, please see example image below. Can I please get advised here. Thanks.
I would load the list of VAT updates from the spreadsheet into a dictionary and then load the 30k record from CRM into memory. Then I would match them up and use ExecuteMultipleRequest to do the updates. Alternatively, you could query CRM using the account numbers (if the list is small enough.) I made the assumption you had thousands of updates to do across the record set of 30k. Note, if the Account record size was very large and couldn't be loaded into memory you would need to do account number queries.
Here is the rough code for the basic solution (I haven't tested, method should be split up, and there is minimal error handling):
public class VatInfo
{
public string RegistrationNumber;
public string TaxNumber;
public static Dictionary<string, VatInfo> GetVatList()
{
//TODO: Implement logic to load CSV file into a list. Dictionary key value should be Account Number
throw new NotImplementedException();
}
}
public class UpdateVatDemo
{
public const int maxBatchSize = 100;
public static void RunVatUpdate(IOrganizationService conn)
{
var vats = VatInfo.GetVatList();
var pagingQuery = new QueryExpression("account");
pagingQuery.ColumnSet = new ColumnSet("accountnumber");
Queue<Entity> allEnts = new Queue<Entity>();
while (true)
{
var results = conn.RetrieveMultiple(pagingQuery);
if (results.Entities != null && results.Entities.Any())
results.Entities.ToList().ForEach(allEnts.Enqueue);
if (!results.MoreRecords) break;
pagingQuery.PageInfo.PageNumber++;
pagingQuery.PageInfo.PagingCookie = results.PagingCookie;
}
ExecuteMultipleRequest emr = null;
while (allEnts.Any())
{
if (emr == null)
emr = new ExecuteMultipleRequest()
{
Settings = new ExecuteMultipleSettings()
{
ContinueOnError = true,
ReturnResponses = true
},
Requests = new OrganizationRequestCollection()
};
var ent = allEnts.Dequeue();
if (vats.ContainsKey(ent.GetAttributeValue<string>("accountnumber")))
{
var newEnt = new Entity("account", ent.Id);
newEnt.Attributes.Add("new_vatno", vats[ent.GetAttributeValue<string>("accountnumber")].TaxNumber);
newEnt.Attributes.Add("new_registrationnumber", vats[ent.GetAttributeValue<string>("accountnumber")].RegistrationNumber);
emr.Requests.Add(new UpdateRequest() { Target = newEnt });
}
if (emr.Requests.Count >= maxBatchSize)
{
try
{
var emResponse = (ExecuteMultipleResponse) conn.Execute(emr);
foreach (
var responseItem in emResponse.Responses.Where(responseItem => responseItem.Fault != null))
DisplayFault(emr.Requests[responseItem.RequestIndex],
responseItem.RequestIndex, responseItem.Fault);
}
catch (Exception ex)
{
Console.WriteLine($"Exception during ExecuteMultiple: {ex.Message}");
throw;
}
emr = null;
}
}
}
private static void DisplayFault(OrganizationRequest organizationRequest, int count,
OrganizationServiceFault organizationServiceFault)
{
Console.WriteLine(
"A fault occurred when processing {1} request, at index {0} in the request collection with a fault message: {2}",
count + 1,
organizationRequest.RequestName,
organizationServiceFault.Message);
}
}
Updating the fetched entity is bound to fail because of its entity state, which would not be null.
To update the fetched entities, you need to new up the entity:
foreach (var acc in response.Entities)
{
var updateAccount = new Entity("account") { Id = acc.Id };
updateAccount .Attributes["new_vatno"] = null; //using null as an example.
updateAccount .Attributes["new_registrationnumber"] = null;
service.Update(acc);
}
Code below shows how I managed to get it righy. forst let me explain. I imported my records into a seperate SQL table, in my code I read that table into a list in memory, I then query CRM accounts that need to be updated, I then loop though each account and check if the account number in CRM matches the account number from my sql database, if it matches, I then update the relevant Reg no and Vat no, See code below:
List<Sheet1_> crmAccountList = new List<Sheet1_>();
//var crmAccount = db.Sheet1_.Select(x => x).ToList().Take(2);
var crmAccounts = db.Sheet1_.Select(x => x).ToList();
foreach (var dbAccount in crmAccounts)
{
CRMDataObject modelObject = new CRMDataObject()
{
ID = dbAccount.ID,
Account_No = dbAccount.Account_No,
Tax_No = dbAccount.Tax_No.ToString(),
Reg_No = dbAccount.Reg_No
//Tarsus_Country = dbAccount.Main_Phone
};
}
var officialDatabaseList = crmAccounts;
foreach (var crmAcc in officialDatabaseList)
{
QueryExpression qe = new QueryExpression();
qe.EntityName = "account";
qe.ColumnSet = new ColumnSet("accountnumber", "new_vatno", "new_registrationnumber");
qe.Criteria.AddCondition("accountnumber", ConditionOperator.In,'list of account numbers go here'
EntityCollection response = service.RetrieveMultiple(qe);
foreach (var acc in response.Entities)
{
if (crmAcc.Account_No == acc.Attributes["accountnumber"].ToString())
{
//acc.Attributes["new_vatno"] = crmAcc.VAT_No.ToString();
acc.Attributes["new_registrationnumber"] = crmAcc.Reg_No.ToString();
service.Update(acc);
}
}
}

Login to multiple accounts using the same loop statement

All I need is a more reliable and stable way of logging into multiple account (not all at once) using a loop that's all. I have already an example code that works but isn't all that stable.
string email_1 = "email_1";
string password_1 = "password_1";
string email_2 = "email_2";
string password_2 = "password_2";
int k = 1;
do
{
string e = null;
string p = null;
if (k == 1)
{
e = email_2;
p = password_2;
}
if (k == 2)
{
e = email_1;
p = password_1;
}
_driver.FindElement.(id("submit_email")).sendkeys(e);
IWebElement s = _driver.FindElement.(id("submit_password"));
s.Sendkeys(p);
s.Submit();
//do stuff
_driver.FindElement(id("logout")).Click();
k++;
} while (k <= 2);
Any ideas on how to make it more stable and reliable, or maybe a better approach to it?
You're gonna need to completely refactor this code. Have you ever practiced object oriented design?
Create this class:
public class Account // Stores the email and password of each account
{
public string Email;
public string Password;
public Account(string email, string password) // Constructor
{
Email = email;
Password = password;
}
}
Then use this class like so:
// Keep all the accounts in one place
List<Account> accounts = new List<Account>()
{
new Account("email_1", "password_1"), // Create a new account
new Account("email_2", "password_2") // Create another account
};
foreach(Account account in accounts)
{
_driver.FindElement.(id("submit_email)).sendkeys(account.Email);
IWebElement s = _driver.FindElement.(id("submit_password"));
s.Sendkeys(account.Password);
s.Submit();
// do stuff
_driver.FindElement(id("logout")).Click();
}
This code is highly expandable and reusable. If you want to add another account, you use the new Account(string, string), statement in the List and that's the only change that needs to be made.

Fetch the objectId from Parse.ParseObject

I am trying to figure out how to obtain the objectId from an query. What i am trying to accomplish is that I want to know if a object with a specific username and password exists in my class and then if yes, get the objectId and save it in my Unity game!
Here is how I am trying to do so with no luck:
void OnClick(){
PrimeAI.ShowSpinner();
LoginUsername = GameObject.Find("UsernameLogin").GetComponent<UIInput>().value;
LoginPassword = GameObject.Find("PasswordLogin").GetComponent<UIInput>().value;
var query = ParseObject.GetQuery("Players")
.WhereEqualTo("playername", LoginUsername)
.WhereEqualTo("password", Constant.Md5Sum(LoginPassword));
query.CountAsync().ContinueWith(t => {
int count = t.Result;
if(count == 1){
GetUserData(LoginUsername);
} else {
LoginError = true;
}
});
}
public void GetUserData(string UserName){
var query = ParseObject.GetQuery("Players")
.WhereEqualTo("playername", UserName);
query.FindAsync().ContinueWith(t => {
IEnumerable<ParseObject> results = t.Result;
OnlyOnce = true;
foreach (var result in results) {
print("Here: "+result["objectId"]);
}
});
}
It works fine until the foreach loop... How can I accomplish this and what am i doing wrong?
Any help is appreciated :-)
Do a Find rather than a CountAsync. Then just access the objectID from the returned object. If you are concerned about moving the whole object when you don't need it, use selectKeys to select only the attributes you want.

foreach (var result in results) {
print("Here: "+ result.objectId);
}

Searching for lastLogon attribute of user in multiple domain servers

First of all, please forgive me if I'm not using the correct terminologies. Correct me wherever I'm using the wrong terminology.
The objective is to programmatically retrieve the lastLogon date of a given username.
We have what I believe is a forest; two AD servers like - adserver01.aa.mycompany.com and adserver02.aa.mycompany.com
I connected to these servers from a third machine using Microsoft's ADExplorer to inspect the objects. There I see some users having lastLogon date available in adserver01, but not in adserver02. For example, the value for lastLogon is 0x0 in adserver02 whereas it is a valid date in adserver01 for some users.
The code I've developed so far as a Windows Forms application, works fine if only one AD Server is involved. How do I check both servers and return the non-zero value if available, in either for lastLogon date attribute?
private static string GetLastActivityDate(string UserName)
{
string domainAndUserName = String.Format(#"LDAP://aa.mycompany.com/CN={0},OU=CLIENT_PROD,OU=clients.mycompany.com,DC=aa,DC=mycompany,DC=com", UserName);
string OUAdminUserName = "abc";
string OUAdminPassword = "xyz";
AuthenticationTypes at = AuthenticationTypes.Secure;
DateTime lastActivityDate;
string returnvalue;
long lastLogonDateAsLong;
using (DirectoryEntry entryUser = new DirectoryEntry(domainAndUserName, OUAdminUserName, OUAdminPassword, at))
using (DirectorySearcher mysearcher = new DirectorySearcher(entryUser))
try
{
using (SearchResultCollection results = mysearcher.FindAll())
{
if (results.Count >= 1)
{
DirectoryEntry de = results[0].GetDirectoryEntry();
lastLogonDateAsLong = GetInt64(de, "lastLogon");
try
{
if (lastLogonDateAsLong != -1)
{
lastActivityDate = DateTime.FromFileTime(lastLogonDateAsLong);
returnvalue = lastActivityDate.ToString();
}
else
{
returnvalue = "-Not available-";
}
}
catch (System.ArgumentOutOfRangeException aore)
{
returnvalue = "Not available";
}
}
else
{
returnvalue = string.Empty;
}
}
}
catch (System.DirectoryServices.DirectoryServicesCOMException dsce)
{
returnvalue = "- Not available -";
}
return returnvalue;
}
Thank you.
EDIT:
private static Int64 GetInt64(DirectoryEntry entry, string attr)
{
DirectorySearcher ds = new DirectorySearcher(
entry,
String.Format("({0}=*)", attr),
new string[] { attr },
SearchScope.Base
);
SearchResult sr = ds.FindOne();
if (sr != null)
{
if (sr.Properties.Contains(attr))
{
return (Int64)sr.Properties[attr][0];
}
}
return -1;
}
Forgot to mention, the AD schema, structure etc, looks exactly alike in the two servers.

http://www.codeproject.com/Articles/19181/Find-LastLogon-Across-All-Windows-Domain-Controlle
I had the same issue but but only for one domain,
I solved it by using the following code however i'm checking the lastLogin of all users
public static Dictionary<string, DateTime> UsersLastLogOnDate()
{
var lastLogins = new Dictionary<string, DateTime>();
DomainControllerCollection domains = Domain.GetCurrentDomain().DomainControllers;
foreach (DomainController controller in domains)
{
try
{
using (var directoryEntry = new DirectoryEntry(string.Format("LDAP://{0}", controller.Name)))
{
using (var searcher = new DirectorySearcher(directoryEntry))
{
searcher.PageSize = 1000;
searcher.Filter = "(&(objectClass=user)(!objectClass=computer))";
searcher.PropertiesToLoad.AddRange(new[] { "distinguishedName", "lastLogon" });
foreach (SearchResult searchResult in searcher.FindAll())
{
if (searchResult.Properties.Contains("lastLogon"))
{
var lastLogOn = DateTime.FromFileTime((long)searchResult.Properties["lastLogon"][0]);
var username = Parser.ParseLdapAttrValue(searchResult.Properties["distinguishedName"][0].ToString());
if (lastLogins.ContainsKey(username))
{
if (DateTime.Compare(lastLogOn, lastLogins[username]) > 0)
{
lastLogins[username] = lastLogOn;
}
}
else
{
lastLogins.Add(username, lastLogOn);
}
}
}
}
}
}
catch (System.Runtime.InteropServices.COMException comException)
{
// Domain controller is down or not responding
Log.DebugFormat("Domain controller {0} is not responding.",controller.Name);
Log.Error("Error in one of the domain controllers.", comException);
continue;
}
}
return lastLogins;
}
On top of the code you can use the following to get all domains in a forest.
Forest currentForest = Forest.GetCurrentForest();
DomainCollection domains = currentForest.Domains;
foreach(Domain domain in domains)
{
// check code above
}
There may be a simpler approach? There is actually another attribute lastLogonTimestamp, added with 2003 domain level I think, that tries to keep a single, consistent value across the domain for the last login. Alas, it has a bizarre replication time pattern, and could be up to two weeks out of date.

AD Searches and Properties and dictonary usage

In order to determine if computer accounts are orphaned, I would like to query all domain controllers of all trusted domains to retrieve the lastLogon and lastLogonTimeStamp for all computers. I have a program that works (at least in my test environment), but I have a few questions, that I hope you might be able to answer.
Are the methods I’m using to find the domains and domain controllers and then retrieve the AD information, using the least amount of resources (network / domain controller CPU and RAM) as possible? How could they be improved?
Is it possible to have more than 1 value in a dictionary key / value pair?
Having a dictionary for LastLogIn and a different one for LastLogInTimestamp seems a waste.
Referring to the dictionary and the AD properties: How can I check for non-existent values as opposed to using Try / Catch?
try
{ // Is this DC more current than the last?
if (dict_LastLogIn[pc] < (long)result.Properties["lastlogon"][0])
{
dict_LastLogIn[pc] = (long)result.Properties["lastlogon"][0];
}
}
catch
{ // The item doesn't exist yet..
try
{
dict_LastLogIn[pc] = (long)result.Properties["lastlogon"][0];
}
catch
{ // .. or
// There is no last LastLogin...
dict_LastLogIn[pc] = 0;

Thanks for any help you can offer.
At a high level, I'm not sure what your end-game is with this, but, are you sure you really want to query every single DC for lastLogon? This could be really expensive. Also, why are you walking trust chains? Are you sure you don't just want all the domains in a given Forest (Forest.Domains)?
In answer to your questions:
This looks OK perf-wise, however you should do a couple things:
Tweak your filter to (&(objectCategory=computer)(objectClass=computer))
Add mySearcher.PageSize = 1000
Remove mySearcher.SizeLimit = int.MaxValue
You could use a Tuple - http://msdn.microsoft.com/en-us/library/system.tuple(VS.90).aspx. Or just define a custom class as your value and then declare Dictionary as your dictionary:
public class LogonTimeStamps
{
public long LastLogon { get; set; }
public long LastLogonTimeStamp { get; set; }
}
For the Dictionary, use myDictionary.ContainsKey(yourKey). For AD, you should be able to use result.Properties.Contains("yourAttribute").
