Multithreaded Selenium Bot does not work correctly

I wrote a bot in C#, I used Selenium.
Problem: When I start more threads at same time, the bot does the work in the first window. All of the e-mail addresses are being added to the "E-mail" textbox in the same window instead of one e-mail address per window.
But it should look like:
Start function: DivisionStart()
private void DivisionStart() {
foreach(var account in BotConfig.AccountList) {
while (CurrentBotThreads >= BotConfig.MaxLoginsAtSameTime) {
Thread.Sleep(1000);
}
StartedBotThreads++;
CurrentBotThreads++;
int startIndex = (StartedBotThreads * BotConfig.AdsPerAccount + 1) - BotConfig.AdsPerAccount - 1;
int stopIndex = BotConfig.AdsPerAccount * CurrentBotThreads;
if (stopIndex > BotConfig.ProductList.Count) {
stopIndex = BotConfig.ProductList.Count;
}
Debug.Print("Thread: " + StartedBotThreads);
var adList = GetAdListBy(startIndex, stopIndex);
foreach(var ad in adList) {
Debug.Print("Für thread: " + StartedBotThreads + " | Anzeige: " + ad.AdTitle);
}
Debug.Print("Parallel");
var ebayBotThread = new Thread(() => {
var botOptions = new IBotOptionsModel() {
CaptchaSolverApiKey = CaptchaSolverApiKey,
ReCaptchaSiteKey = "6LcZlE0UAAAAAFQKM6e6WA2XynMyr6WFd5z1l1Nr",
StartPageUrl = "https://www.ebay-kleinanzeigen.de/m-einloggen.html?targetUrl=/",
EbayLoginEmail = account.AccountEmail,
EbayLoginPassword = account.AccountPassword,
Ads = adList,
};
var ebayBot = new EbayBot(this, botOptions);
ebayBot.Start(StartedBotThreads);
Thread.Sleep(5000);
});
ebayBotThread.Start();

}
If I remove the Thread.Sleep(5000); in the DivisionStart function it will work, but I need it I actually want to wait for a found proxy but I simulated it with Thread.Sleep
How can I solve my problem?
Thanks for any answer!

I fixed it.
I used UndetectedChromeDriver wich does not use different ports.
I use another Undetected driver now.
Thank you all

SQLite table doesn't get updated

I have a problem. I created a SwitchButton and want to store the state in a database table. So I created this code to debug:
SettingSwitch.CheckedChange += (s, b) =>
{
SettingDb testsetting = new SettingDb
{
Name = mItems[position].Name,
};
SettingDb test = MainActivity.db.SelectRowFromTableSettings(testsetting);
if (test != null)
{
bool SwitchValueBool = Convert.ToBoolean(test.Value);
}
bool isChecked = ValueDictionary[position];
if(isChecked == true)
{
isChecked = false;
}
else if(isChecked == false)
{
isChecked = true;
}
SettingDb setting = new SettingDb()
{
Name = SettingName.Text,
Type = "Switch",
Value = isChecked.ToString()
};
MainActivity.db.UpdateTableSettings(setting);
ValueDictionary[position] = isChecked;
SettingDb test2 = MainActivity.db.SelectRowFromTableSettings(testsetting);
if (test2 != null)
{
bool SwitchValueBool = Convert.ToBoolean(test2.Value);
}
};
The expected outcome should be:
test.Value = False
test2.Value = Opposite of test.Value, so True
But now the value I get from the table is always False. Here is the update function:
string folder = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
public bool UpdateTableSettings(SettingDb setting)
{
try
{
using (var connection = new SQLiteConnection(System.IO.Path.Combine(folder, "Settings.db")))
{
connection.BeginTransaction();
connection.Query<SettingDb>("UPDATE SettingDb SET Value=? WHERE Name=?", setting.Value, setting.Name);
//connection.Update(setting);
connection.Commit();
return true;
}
}
catch (SQLiteException ex)
{
Log.Info("SQLiteEx", ex.Message);
return false;
}
}
public SettingDb SelectRowFromTableSettings(SettingDb setting)
{
try
{
using (var connection = new SQLiteConnection(System.IO.Path.Combine(folder, "Settings.db")))
{
return connection.Query<SettingDb>("SELECT * FROM SettingDb WHERE Name=?", setting.Name).FirstOrDefault();
}
}
catch (SQLiteException ex)
{
Log.Info("SQLiteEx", ex.Message);
return null;
}
}
The table value doesn't get updated!!!
Can someone tell me what I am doing wrong?
Please let me know!

According to your description, you want to update sqlite database table, please take a look the following code and modify the update function.
static void UpdateDatabase(int primaryKey, string newText, int newValue)
{
string path = Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments), "mydatabase.db");
var db = new SQLiteConnection(path, false);
string sql = "UPDATE MyTable SET MyTextColumn = ?, MyValueColumn = ? WHERE MyPrimaryKey= ?";
string[] parms = new String[] { newText, newValue.ToString(), primaryKey.ToString() };
var cmd = db.CreateCommand(sql, parms);
cmd.ExecuteNonQuery();
}

Is creating an EPT (MS PS Enteprise Project Type) via PSI/CSOM possible?

The following code does not throw any exception but it also doesn't create a new EPT:
public void CreateEnterpriseProjectType(Guid eptGuid, string eptName, string eptDescription)
{
ProjectContext pwaContext = new ProjectContext("http://serverName/pwaName");
pwaContext.Credentials = new NetworkCredential("adminUsername", "adminPassword", "domainName");
EnterpriseProjectTypeCreationInformation eptData = new EnterpriseProjectTypeCreationInformation();
eptData.Id = eptGuid;
eptData.Name = eptName;
eptData.Description = eptDescription;
eptData.IsDefault = false;
eptData.IsManaged = true;
eptData.WorkspaceTemplateName = "PROJECTSITE#0";
eptData.ProjectPlanTemplateId = Guid.Empty;
eptData.WorkflowAssociationId = Guid.Empty;
// Get the maximum order of the existing EPTs and increment by 1 in order to use an order that does not already exist
eptData.Order = Convert.ToInt32(Database.GetValue("SELECT MAX(ENTERPRISE_PROJECT_TYPE_ORDER) FROM [ProjectWebApp].[pub].[MSP_ENTERPRISE_PROJECT_TYPES]")) + 1;
pwaContext.Load(pwaContext.ProjectDetailPages);
pwaContext.ExecuteQuery();
List<ProjectDetailPageCreationInformation> projectDetailPages = new List<ProjectDetailPageCreationInformation>() {new ProjectDetailPageCreationInformation() { Id = pwaContext.ProjectDetailPages[1].Id, IsCreate = false }};
eptData.ProjectDetailPages = projectDetailPages;
EnterpriseProjectType newEpt = pwaContext.EnterpriseProjectTypes.Add(eptData);
pwaContext.EnterpriseProjectTypes.Update();
}
Any ideas on what I'm doing wrong or what I'm missing? Is it possible to create an EPT programmatically?

Yes, it is possible to create an EPT programmatically. Turns out three things were missing:
A second PDP having IsCreate = true (at least one with IsCreate = true and one with IsCreate = false are required for successfully creating an EPT)
A query for iterating through the existing EPTs before adding a new one:
pwaContext.Load(pwaContext.EnterpriseProjectTypes);
pwaContext.ExecuteQuery();
A pwaContext.ExecuteQuery(); after the pwaContext.EnterpriseProjectTypes.Update(); command.

The following code works fine for me:
public class PSI
{
private ProjectContext _context;
private string basicEpt = "Enterprise Project"; // Basic enterprise project type.
private static readonly PSI psi = new PSI();
private int timeoutSeconds = 60;
SvcProject.ProjectClient _prClient;
private PSI ()
{
_context = new ProjectContext(System.Configuration.ConfigurationManager.AppSettings["PwaUrl"]);
//credentials of currently running acount or enable line below
//_context.Credentials = new System.Net.NetworkCredential("user", "pass", "domain");
timeoutSeconds = int.Parse(System.Configuration.ConfigurationManager.AppSettings["DefaultTimeoutPwa"]);
_prClient = new SvcProject.ProjectClient("basicHttp_Project");
}
public static PSI Instance
{
get{ return psi; }
}
public Guid GetEptUid(string eptName)
{
Guid eptUid = Guid.Empty;
try
{
var eptList = _context.LoadQuery( _context.EnterpriseProjectTypes.Where(ept => ept.Name == eptName));
_context.ExecuteQuery();
eptUid = eptList.First().Id;
}
catch (Exception ex)
{
string msg = string.Format("GetEptUid: eptName = \"{0}\"\n\n{1}", eptName, ex.GetBaseException().ToString());
throw new ArgumentException(msg);
}
return eptUid;
}
public PublishedProject CreateProject(string prName, string description, DateTime startDate)
{
try
{
System.Console.Write("\nCreating project: {0} ...", prName);
ProjectCreationInformation newProj = new ProjectCreationInformation();
newProj.Id = Guid.NewGuid();
newProj.Name = prName;
newProj.Description = description;
newProj.Start = startDate;
newProj.EnterpriseProjectTypeId = GetEptUid(basicEpt);
PublishedProject newPublishedProj = _context.Projects.Add(newProj);
QueueJob qJob = _context.Projects.Update();
JobState jobState = _context.WaitForQueue(qJob, timeoutSeconds);
if (jobState == JobState.Success)
return newPublishedProj;
else
return null;
}
catch (Exception ex)
{
System.Console.ForegroundColor = ConsoleColor.Red;
System.Console.WriteLine("\nError: {0}", ex.Message);

Sending Multiple Recepients in a single mail: Consequences

While sending email via System.Net.Mail to multiple recipients (one single email with multiple recipients), if one recipients address fail, will the rest reach the email?
There might be duplicates of the same question, but I'm asking something different in contrast.
For prompting such question, I was taken into consideration of Email clients available like Outlook where such does not happen even if one single address failed. Perhaps, System.Net.Mail is a lightweight client and does not allow such functionality? Or is it the way I'm writing my code incorrectly.
I was asked as if why this happens, hope I can get an explanation so that I can pass it by.
I was running such a scenario from my code below:
public void sendBusinessEmail(communication.email.business.config.BusinessEmailList[] aEmailList)
{
System.Net.Mail.MailMessage objMsg = null;
string[] aEmail = null;
System.Net.Mail.SmtpClient objSmtpClient = null;
int iRetries = 0;
if (aEmailList == null)
{
return;
}
try
{
if (Properties.Settings.Default.IS_SMTP_TLS)
{
objSmtpClient = getSMTP_TLS_Client();
ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
}
else
{
objSmtpClient = getSMTP_Default_Client();
}
foreach (communication.email.business.config.BusinessEmailList obj in aEmailList)
{
try
{
objMsg = new System.Net.Mail.MailMessage();
objMsg.From = new System.Net.Mail.MailAddress("jkstock#keells.com", "JKSB Business Services");
aEmail = obj.Emails;
if (Properties.Settings.Default.TO_TEST_EMAIL)
{
objMsg.To.Add(Properties.Settings.Default.TO_TEST_EMAIL_ADDRESS.ToString());
for (int i = 0; i < aEmail.Length; i++)
{
objMsg.Body += aEmail[i] + Environment.NewLine;
}
}
else
{
for (int i = 0; i < aEmail.Length; i++)
{
objMsg.To.Add(new System.Net.Mail.MailAddress(aEmail[i]));
}
objMsg.Body = obj.EmailBody;
}
objMsg.Subject = checkAllReadySent(obj.EmailSubject);
objMsg.Attachments.Add(new System.Net.Mail.Attachment(obj.AttachmentPath, (System.IO.Path.GetExtension(obj.AttachmentPath) == ".pdf" ? System.Net.Mime.MediaTypeNames.Application.Pdf : System.Net.Mime.MediaTypeNames.Application.Octet)));
//sending emails
//send for 5 times if error persists, unless otherwise success
for (int i = 0; i < 5; i++)
{
try
{
objSmtpClient.Send(objMsg);
obj.updateLog("OK", (i+1));
break;
}
catch (Exception e)
{
if (i == 4)
{
obj.updateLog(e.Message, (i+1));
}
}
}
objMsg = null;
}
