I am working on EF. I am trying to insert into a table, the insert function is in a thread.
private void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
{
int bytes = port.BytesToRead;
//string indata = sp.ReadExisting();
Thread.Sleep(50);
try
{
receivedBytes = port.BaseStream.Read(buffer, 0, (int)buffer.Length);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message.ToString());
}
var receiveData = BitConverter.ToString(buffer, 0, receivedBytes);
var finalData = receiveData.Replace("-", "");
//Thread.Sleep(100);
Console.WriteLine("Thread Going to Start");
new Thread(() => {
SaveData(finalData);
}).Start(); // starting the thread
port.DiscardOutBuffer();
port.DiscardInBuffer();
}
And this is my save data function
public void SaveData(string finalData)
{
Console.WriteLine(LineNumber() + "Data Transmiting...");
thread = Thread.CurrentThread;
mdc_dbEntities e = new mdc_dbEntities();
var msn = e.mdc_meter_config.Where(m => m.m_hex == sr).Select(s => new { s.msn, s.p_id, s.meter_id }).ToList();
var H = finalData.Substring(0, 2);
using (mdc_dbEntities u = new mdc_dbEntities())
{
foreach (var res in msn)
{
var cust_id = e.mdc_meter_cust_rel.Where(m => m.msn == res.msn)
.Select(s => s.cust_id)
.FirstOrDefault();
mdc_meters_data data = new mdc_meters_data()
{
msn = res.msn,
cust_id = cust_id,
device_id = res.meter_id.ToString(),
kwh = e_val.ToString(),
voltage_p1 = a_vol_val.ToString(),
voltage_p2 = b_vol_val.ToString(),
voltage_p3 = c_vol_val.ToString(),
current_p1 = a_curr_val.ToString(),
current_p2 = b_curr_val.ToString(),
current_p3 = c_curr_val.ToString(),
data_date_time = Convert.ToDateTime(theDate.ToString(format)),
d_type = d_type.ToString(),
pf1 = a_pf_val.ToString(),
pf2 = b_pf_val.ToString(),
pf3 = c_pf_val.ToString(),
p_id = res.p_id,
};
u.mdc_meters_data.Add(data);
}
u.SaveChanges();
}
Console.WriteLine(LineNumber() + "Data Saved");
Thread.Sleep(50);
}
try
{
thread.Abort(); // aborting it after insertion
//Thread.Sleep(50);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message.ToString());
}
}
The above code runs for some time, but after that I encountered an error at u.SaveChanges();
System.Data.Entity.Core.EntityException: 'An error occurred while closing the provider connection. See the inner exception for details.'
MySqlException: Fatal error encountered during command execution.
MySqlException: Fatal error encountered attempting to read the resultset.
MySqlException: Reading from the stream has failed.
IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
I have looked into each solution and tried them but still unable to resolve this issue. I must be missing something that I don't know.

Any help would be highly appreciated.
Executing EF related changes in a manually initiated thread is not a good idea. Try to run the EF changes in the same thread. If you are bothered with processing incoming requests, use Async, and Await feature. I have modified your code to accommodate this feature. Please try this.
private void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
{
int bytes = port.BytesToRead;
//string indata = sp.ReadExisting();
try
{
receivedBytes = port.BaseStream.Read(buffer, 0, (int)buffer.Length);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message.ToString());
}
var receiveData = BitConverter.ToString(buffer, 0, receivedBytes);
var finalData = receiveData.Replace("-", "");
Console.WriteLine("Thread Going to Start");
SaveDataAsync(finalData).Wait(); // this call will become sync and runs under main thread.
port.DiscardOutBuffer();
port.DiscardInBuffer();
}
public async Task<bool> SaveDataAsync(string finalData)
{
mdc_dbEntities e = new mdc_dbEntities();
var msn = e.mdc_meter_config.Where(m => m.m_hex == sr).Select(s => new { s.msn, s.p_id, s.meter_id }).ToList();
var H = finalData.Substring(0, 2);
var isSaveSuccess = false;
using (mdc_dbEntities u = new mdc_dbEntities())
{
foreach (var res in msn)
{
var cust_id = e.mdc_meter_cust_rel.Where(m => m.msn == res.msn)
.Select(s => s.cust_id)
.FirstOrDefault();
mdc_meters_data data = new mdc_meters_data()
{
msn = res.msn,
cust_id = cust_id,
device_id = res.meter_id.ToString(),
kwh = e_val.ToString(),
voltage_p1 = a_vol_val.ToString(),

voltage_p3 = c_vol_val.ToString(),
current_p1 = a_curr_val.ToString(),
current_p2 = b_curr_val.ToString(),

data_date_time = Convert.ToDateTime(theDate.ToString(format)),

u.mdc_meters_data.Add(data);
}
isSaveSuccess = (await u.SaveChangesAsync())>0; // if records inserted, the count will be more than 0

this is easier to read and may help
saying all this please ensure that you can actually make a connection to the db
double check connectionString

I'm using Entity Framework to add new records to the database, everything goes ok without any errors, but I don't see the new record in the database.
Update code works, but insert code doesn't work. No errors appear, but no records are inserted into the database.
My code :
var DBs2 = ConnectionTools.OpenConn();
DBs2.Configuration.AutoDetectChangesEnabled = false;
DBs2.Configuration.ValidateOnSaveEnabled = false;
var resList = CreatedSerials.Where(u => u.Item4 == VID).ToList();
foreach (var r in resList)
{
// if serial id ==0 => new then add it as new
if ( r.Item7 == 0)
{
try
{
var purchasesItemSerials = new purchases_item_seriels()
{
pitem_ID = pitem_ID,
stitems_ID = r.Item1,
pmain_ID = PurchasesID,
pitem_virtualID = r.Item4,
pis_CustomSerial = r.Item2,
pis_ExpireDate = r.Item3,
pis_Statues = 0,
ss_StoreID = Convert.ToInt32(gridView1.GetRowCellValue(ItemImdex, "storeID")),
Purchases_Price = Convert.ToDecimal(gridView1.GetRowCellValue(ItemImdex, "item_NetSmallestUnitPrice")),
};
ss.Add(purchasesItemSerials);
}
catch (Exception eeeeee)
{
Msg.Show("", eeeeee.ToString(), 0);return;
}
}
else
{
var DBs350 = ConnectionTools.OpenConn();
var UpdateSerial = DBs350.purchases_item_seriels.Find(r.Item7);
UpdateSerial.pitem_ID = pitem_ID;
UpdateSerial.stitems_ID = r.Item1;
UpdateSerial. pmain_ID = PurchasesID;
UpdateSerial.pitem_virtualID = r.Item4;
UpdateSerial.pis_CustomSerial = r.Item2;
UpdateSerial.pis_ExpireDate = r.Item3;
UpdateSerial.pis_Statues = r.Item6;
UpdateSerial.ss_StoreID = Convert.ToInt32(gridView1.GetRowCellValue(ItemImdex, "storeID"));
UpdateSerial.Purchases_Price = Convert.ToDecimal(gridView1.GetRowCellValue(ItemImdex, "item_NetSmallestUnitPrice"));
DBs350.SaveChanges();
}
}
try
{
DBs2.purchases_item_seriels.AddRange(ss);
DBs2.SaveChanges();
}
catch (Exception eeeeee)
{
Msg.Show("", eeeeee.ToString(), 0);return;
}
I also tried :
DBs2.Configuration.AutoDetectChangesEnabled = true;
DBs2.Configuration.ValidateOnSaveEnabled = true;
but again: no data is inserted, no errors appear
I also tried :
int returnCode = DBs2.SaveChanges();
and returnCode = 0
**I also tried : inserting just a single item then SaveChanges **
// if this serial is new
var NewSerialresList = CreatedSerials.Where(u => u.Item4 == VID && u.Item7 == 0).ToList();
if (NewSerialresList.Count() > 0)
{
var ss = new List<purchases_item_seriels>();
foreach (var r in NewSerialresList)
{
try
{
mrsalesdbEntities DBs002 = new mrsalesdbEntities();
var purchasesItemSerials = new purchases_item_seriels()
{
pitem_ID = pitem_ID,
stitems_ID = r.Item1,
pmain_ID = PurchasesID,
pitem_virtualID = r.Item4,
pis_CustomSerial = r.Item2,
pis_ExpireDate = r.Item3,
pis_Statues = 0,
ss_StoreID = Convert.ToInt32(gridView1.GetRowCellValue(ItemImdex, "storeID")),
Purchases_Price = Convert.ToDecimal(gridView1.GetRowCellValue(ItemImdex, "item_NetSmallestUnitPrice")),
};
//ss.Add(purchasesItemSerials);
DBs002.purchases_item_seriels.Add(purchasesItemSerials);
DBs002.SaveChanges();
}
catch (Exception ex)
{
Msg.Show("", ex.ToString(), 0);
}
}
int CC = ss.Count();
}

Below My Code that gets info of Bug history from QC. I have problem with
AuditPropertyFactoryFilter which does not filter. AuditPropertyFactory has more than thousand rows.
If I comment
var changesList = auditPropertyFactory.NewList(changesHistoryFilter.Text); and uncomment
next line, auditPropertyFactory has several rows only but it isn't filtered as i need.
Can anyone get some advice?
public List<QCBugHistory> retrieveHistoryFromBug(string bugId)
{
List<QCBugHistory> history = new List<QCBugHistory>();
try
{
TDConnection qcConnection = new TDConnection();
qcConnection.InitConnectionEx(qcUrl);
qcConnection.ConnectProjectEx(qcDomain, qcProject, qcLogin);
if (qcConnection.Connected)
{
AuditRecordFactory auditFactory = qcConnection.AuditRecordFactory as AuditRecordFactory;
TDFilter historyFilter = auditFactory.Filter;
historyFilter["AU_ENTITY_TYPE"] = "BUG";
historyFilter["AU_ENTITY_ID"] = bugId;
historyFilter["AU_ACTION"] = "Update";
historyFilter.Order["AU_TIME"] = 1;
historyFilter.OrderDirection["AU_TIME"] = 1;
var auditRecordList = auditFactory.NewList(historyFilter.Text);
log.Info("кол-во в истории " + auditRecordList.Count);
if (auditRecordList.Count > 0)
{
foreach (AuditRecord audit in auditRecordList)
{
QCBugHistory bugHistory = new QCBugHistory();
bugHistory.actionType = audit["AU_ACTION"];
bugHistory.changeDate = audit["AU_TIME"];
AuditPropertyFactory auditPropertyFactory = audit.AuditPropertyFactory;
var changesHistoryFilter = auditPropertyFactory.Filter;
changesHistoryFilter["AP_PROPERTY_NAME"] = "Status";
var changesList = auditPropertyFactory.NewList(changesHistoryFilter.Text);
//var changesList = auditPropertyFactory.NewList("");
if (changesList.Count > 0)
{
foreach (AuditProperty prop in changesList)
{
//prop.EntityID
if (prop["AP_PROPERTY_NAME"] == "Status")
{
bugHistory.oldValue = prop["AP_OLD_VALUE"];
bugHistory.newValue = prop["AP_NEW_VALUE"];
history.Add(bugHistory);
}
}
}
}
}
}
}
catch (Exception e)
{
log.Error("Проблема соединения и получения данных из QC ", e);
}
return history;
}
Try this (in C#):
1) Having only BUG ID param (BUGID below):
BugFactory bgFact = TDCONNECTION.BugFactory;
TDFilter bgFilt = bgFact.Filter;
bgFilt["BG_BUG_ID"] = BUGID; // This is a STRING
List bugs = bgFilt.NewList();
Bug bug = bugs[1]; // is 1-based
bug.History;
2) Having the Bug object itself, just do:
bug.History;

Everything starts fine and I get no exceptions but I'm getting no results and the code gets stuck one the line that I marked and the memory keeps shooting up. I figured the problem was with the above code because maybe I was doing something wrong. I just don't know where to start as this is my first time dealing with plinq/parallel processing and the tutorials don't show anything this complex.
I'm issue when I get +CDS in AT COMMAND throught c# using SerialPort, any times I get this +CDS truncated, example:
+CDS: 25
0002970C91555868047414212181414094882121814140948830
Why I've this problem, why any times work nice?

this.NewLine = "\r\n";
this.ReadBufferSize = 1024;
}
public static void TestPort()
{
var p = new PortCom("COM12");
if (!p.IsOpen)
p.Open();
p.StatusPort = StatusPorta.Ready;
p.DataReceived += new SerialDataReceivedEventHandler(p_DataReceivedSample);
p.PinChanged += new SerialPinChangedEventHandler(p_PinChanged);
p.ErrorReceived += new SerialErrorReceivedEventHandler(p_ErrorReceived);
p.Disposed += new EventHandler((obj, porta) =>
{
Console.WriteLine(((PortaCOM)obj).ToString());
});
if (Console.ReadKey().Key == ConsoleKey.B)
{
p.Close();
p.Dispose();
}
}
static void p_DataReceivedSample(object sender, SerialDataReceivedEventArgs e)
{
var p = (PortaCOM)sender;
try
{
Console.WriteLine(p.ReadExisting());
var sb = new StringBuilder();
sb.Append(p.ReadExisting());
int y = sb.ToString().IndexOf("\r\n");
var stop = Stopwatch.StartNew();
stop.Start();
while (y == -1)
{
sb.Append(p.ReadExisting());
y = sb.ToString().IndexOf("\r\n");
if (stop.Elapsed.TotalSeconds > 10)
break;
}
stop.Stop();
var _retorno = sb.ToString();
var cmt = regCMT.Match(_retorno);
var succ = regSucess.Match(_retorno);

Please I really need help with it, I'm glad for any help!
+cds is alert for incoming message with message location on SIM memeory.
so here its seems in PDU mode data. and it is seems may be flash message content.
Convert the data PDU mode to Text mode to receive message.
