Error log inside thread not working sometime

I am calling following method inside thread. inside method i have written logs which writes some variable values in notepad file.
Problem : Sometime last log of method do not log anything. ie last line not exucuting sometime. i am not able to understand problem. please guide me if there are issue somewhere.
This is web application hosted in iis server.
Function :
public bool ResetEmployeeAssignedCoursesByRole()
{
bool bReturn = false;
DbTransactionHelper dbTransactionHelper = new DbTransactionHelper();
dbTransactionHelper.BeginTransaction();
try
{
// this line execuete fine
ErrorLog.createRoleLog("Method sp_Reset_EmpAssignedCoursesByRole Started " + this.RoleID + " Course ID " + this.CourseID + " External Message " + sMessage);
StringBuilder sbQueryEmployeeCourse = new StringBuilder();
sbQueryEmployeeCourse.Append(" set #roleID = " + roleID + "; ");
sbQueryEmployeeCourse.Append(" set #courseID = " + courseID + "; ");
sbQueryEmployeeCourse.Append(" set #inActiveReason = " + inActiveReason + "; ");
sbQueryEmployeeCourse.Append(" set #lastRecordUpdateSource = " + lastRecordUpdateSource + "; ");
sbQueryEmployeeCourse.Append(" call sp_Reset_EmpAssignedCoursesByRole (#roleID, #courseID, #inActiveReason, #lastRecordUpdateSource); ");
DataTable dtEmployeeCourse = dbTransactionHelper.GetDataTable(BusinessUtility.GetString(sbQueryEmployeeCourse), CommandType.Text, null
);
dbTransactionHelper.CommitTransaction();
bReturn = true;
// this line not execuete sometime.
ErrorLog.createRoleLog("Method sp_Reset_EmpAssignedCoursesByRole Ended " + this.RoleID + " Course ID " + this.CourseID + " External Message " + sMessage);
}
catch (Exception ex)

dbTransactionHelper.RollBackTransaction();
ErrorLog.createRoleLog("Add Course ID " + BusinessUtility.GetString(courseID));
ErrorLog.createRoleLog(ex.ToString());
}
return bReturn;
}
Calls method like below :
Thread t = new Thread(ResetEmployeeAssignedCoursesByRole);
t.Start();
FUNCTION createRoleLog :
public static void createRoleLog(string errorMessage, int empHdrID = 0)
{
try
{

Insert Word Heading with Selection

I try to insert a word heading at a specific position but it is always added at the end of the document. Where is my mistake?:
foreach (Publish p in tempstructure)
{
if (p.element_type_id == 3)
{
Word.Paragraph par = selection.Paragraphs.Add();
par.Range.Text = "test";
par.Range.set_Style(Word.WdBuiltinStyle.wdStyleHeading2);
par.Range.InsertParagraphAfter();
selection.TypeParagraph();
}
else
{
if (File.Exists(#Properties.Settings.Default.documentsPath + p.filename + "_" + language + ".docx"))
{
selection.InsertFile(#Properties.Settings.Default.documentsPath + p.filename + "_" + language + ".docx");
selection = word.Selection;
}
else
{
selection.TypeText("Missing file: " + p.filename + "_" + language + ".docx");
selection.TypeParagraph();
}
}
selection = word.Selection;
}
Best regards ...

The simple solution is:
foreach (Publish p in tempstructure)
{
if (p.element_type_id == 3)
{
selection.set_Style(Word.WdBuiltinStyle.wdStyleHeading2);
selection.TypeText(p.name);
selection.TypeParagraph();
}
else
{
if (File.Exists(#Properties.Settings.Default.documentsPath + p.filename + "_" + language + ".docx"))
{
selection.InsertFile(#Properties.Settings.Default.documentsPath + p.filename + "_" + language + ".docx");
selection = word.Selection;
}
else
{
selection.TypeText("Missing file: " + p.filename + "_" + language + ".docx");
selection.TypeParagraph();
}
}
selection = word.Selection;
}

C# out of memory with file

I'm getting a OutOfMemory exception when running the following code, it happens on the File.ReadLines line, it processes most files fine until it hits larger files.
It's consistantly using tons of memory and cpu during the whole process though.
The file it crashed on is only 156,000KB, which is 156mb
static void Main(string[] args)
{
Console.CursorVisible = false;
Console.ForegroundColor = ConsoleColor.Green;
Console.WriteLine();
Console.WriteLine(" [" + DateTime.Now.ToShortTimeString() + "]" + " Connected to the Cassandra Database");
Console.WriteLine();
Console.ForegroundColor = ConsoleColor.White;
string filepath = #"C:\Users\admin\Desktop\wecrack lists";
DirectoryInfo directory = new DirectoryInfo(filepath);
int fileCount = 0;
var client = new MongoClient("mongodb://localhost:27017");
var database = client.GetDatabase("cracking");
var collection = database.GetCollection<Password>("passwords");
foreach (var file in directory.GetFiles("*"))
{
fileCount++;
Console.WriteLine(" [" + DateTime.Now.ToShortTimeString() + "]" + " Working through file: {" + file + "} {" + fileCount + "/" + directory.GetFiles("*").Count() + "}");
List<Password> entitys = new List<Password>();
foreach (string line in File.ReadLines(filepath + #"\" + file.ToString()))
{
entitys.Add(new Password { password = line });
}
collection.InsertManyAsync(entitys);
}
Console.WriteLine();
Console.WriteLine(" [" + DateTime.Now.ToShortTimeString() + "]" + " Finished inserting records, press any key to get the count.");
Console.ReadKey(true);
while (true)
{
Console.ReadKey(true);
}
}

Try batching your updates. That way you won't have all that data in memory at the same time. It may also help you not totally lock up your database.
...
foreach (var file in directory.GetFiles("*"))
{
fileCount++;
Console.WriteLine(" [" + DateTime.Now.ToShortTimeString() + "]" + " Working through file: {" + file + "} {" + fileCount + "/" + directory.GetFiles("*").Count() + "}");
System.IO.StreamReader file = new System.IO.StreamReader(filepath + #"\" + file.ToString());
while(!file.EndOfStream)
{
int passwordBatchCount = 0;
List<Password> entitysBatch = new List<Password>();
while ((string line = file.ReadLine()) != null && passwordBatchCount < BATCH_SIZE)
{
entitysBatch.Add(new Password { password = line });
passwordBatchCount++;
}
collection.InsertManyAsync(entitysBatch);
}
file.Close();
}

exiting console application c# and writing to log

So I'm trying to exit a console application IF a parameter check fails, however, I still want it to log to a file. The logging to a file works fine as long as all the parameters are good. However, when a parameter check fails and hits the System.Environment.Exit(0) portion, the log file is still completely empty. Here's the code so far. Please help, I've tried everything I could think of.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace I2C_File_Splitter
{
class Program
{
static void Main(string[] args)
{
//get command line input paramaters
using (StreamWriter log = File.AppendText("Splitter_log.txt"))
{
log.WriteLine(DateTime.Now + " ******************************************** SPLITTER STARTED ****************************************************************");
log.WriteLine(DateTime.Now + " FILE: " + args[0] + " DESTINATION: " + args[1] + " MAX COUNT PER FILE: " + args[2]);
if (args.Length == 0)
System.Environment.Exit(0);
string originalFile = args[0];
string destination = args[1];
int fileLength = Convert.ToInt32(args[2]);
string fileName;
string fileExtension;
string line;
int fileNumber = 1;
if (!File.Exists(originalFile))
{
log.WriteLine(DateTime.Now + " Error: Transfund file not found for: " + args[0]);
log.WriteLine(DateTime.Now + " ******************************************** SPLITTER ENDED ****************************************************************");
System.Environment.Exit(0);
}
if (!Directory.Exists(destination))
{
log.WriteLine(DateTime.Now + " Error: destination directory not found for: " + args[1] );
log.WriteLine(DateTime.Now + " ******************************************** SPLITTER ENDED ****************************************************************");
System.Environment.Exit(0);
}
if (fileLength < 0)
{
log.WriteLine(DateTime.Now + " Error: file length must be greater than 0. Incorrect value " + args[2]);
log.WriteLine(DateTime.Now + " ******************************************** SPLITTER ENDED ****************************************************************");
System.Environment.Exit(0);
}
//get file name and file extension
fileName = Path.GetFileNameWithoutExtension(originalFile);
fileExtension = Path.GetExtension(originalFile);
StreamReader file = new StreamReader(originalFile);
log.WriteLine(DateTime.Now + " processing: " + fileName);
string header = file.ReadLine(); //get first line
while ((line = file.ReadLine()) != null)
{
StreamWriter newFile = new StreamWriter(destination + "\\" + fileName + "_" + fileNumber.ToString() + fileExtension);
newFile.WriteLine(header);
newFile.WriteLine(line);
int counter = 1;
while (counter < fileLength)
{
line = file.ReadLine();
if (line == null)
break;
newFile.WriteLine(line);
counter++;
}
newFile.Close();
log.WriteLine(DateTime.Now + " " + fileName + "_" + fileNumber.ToString() + fileExtension + " created. Card count: " + counter);
fileNumber++;
}
log.WriteLine(DateTime.Now + " Processing completed: " + fileName);
log.WriteLine(DateTime.Now + " ******************************************** SPLITTER ENDED ****************************************************************");
}
}
}
}

When you call Environment.Exit, you're telling it to terminate your program immediately.
Your "log" stream never gets flushed (which would happen when you reach the end of the using block), and so nothing gets a chance to be written to the file.
Try flushing the stream before calling exit.
if (!Directory.Exists(destination))
{
log.WriteLine(DateTime.Now + " Error: destination directory not found for: " + args[1] );
log.WriteLine(DateTime.Now + " ******************************************** SPLITTER ENDED ****************************************************************");
// write all pending log messages to the file
log.Flush();
System.Environment.Exit(0);
}

the error i got is in the section below , which is "the current index is out of range"
foreach (XmlNode noeud in listeNode){
txtBoxAffiche.Text += noeud.Attributes[2].InnerText.ToString() +" - "
+ noeud.Attributes[3].InnerText.ToString() + " - "
+ noeud.Attributes[4].InnerText.ToString() +
Environment.NewLine;
}
can you please help me
thank you

Problem : You might be accessing the invalid Attributes of the Pays.xml file.
Solution: You need to check the Attributes.Count property before accessing the Attributes of the Pays.xml file.
Try This:
foreach (XmlNode noeud in listeNode)
{
for(int i=2;i<noeud.Attributes.Count;i++)
{
if(i!=noeud.Attributes.Count-1)
txtBoxAffiche.Text += noeud.Attributes[i].InnerText.ToString() +" - ";
else
txtBoxAffiche.Text += noeud.Attributes[i].InnerText.ToString() + Environment.NewLine;
}
}

The error is due to you are using the Index out of range.
for example if Array size 3 but if you try to access 4th index ,it will give error.
so please check this part for index value
foreach (XmlNode noeud in listeNode){
txtBoxAffiche.Text += noeud.Attributes[2].InnerText.ToString() +" - "
+ noeud.Attributes[3].InnerText.ToString() + " - "
+ noeud.Attributes[4].InnerText.ToString() +
Environment.NewLine;
}

The problem is in one of the Attributes[] index. You get the position 2, 3 and 4, and I bet that you don't have that many Attributes (4, 3 or 2).
You can set that values first to some variables before using them.
string attribute2 = noeud.Attributes[2].InnerText.ToString();
string attribute3 = noeud.Attributes[3].InnerText.ToString();
string attribute4 = noeud.Attributes[4].InnerText.ToString();
But this isn't a very good practice.... You would check first if the attribute exists.
string attribute2;
if (noeud.Attributes[2] != null) {
attribute2 = noeud.Attributes[2].InnerText.ToString();
}
