Crash in MouseKeyHook

can some one take a look to my C# source that has a crash issue? The program is supposed to omit unwanted double clicks the mouse sometimes sends and it works but after a while using the program it crashes.
The line that crashes:
Application.Run(new TheContext());
This is the error code:
An unhandled exception of type 'System.NullReferenceException' occurred in Gma.System.MouseKeyHook.dll

Csvhelper write with windows service

I am using csvhelper with windows service which runs non stop. I want to create a new csv log file and put the header values only once until the file size grown to 1000 kb and then create another new file so the file size grow too big. At the moment csv file is created once when windows service starts but it repeats header values every time it writes into it.
Do we have some config properties in csv helper to flag size file?
Please have a look at the code and suggest if it can be done efficiently in .net 4.0.
Windows Service code
public partial class Service1 : ServiceBase
{
private Thread executeThread;
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
try
{
Thread.Sleep(30000);
executeThread = new Thread(new ThreadStart(Execute));
executeThread.Start();
}
catch (Exception e)
{
Library.LogData("Error : " + DateTime.UtcNow + " " + e.Message);
OnStop();
}
}
protected override void OnStop()
{
try
{
Library.LogData("Stopped: " + DateTime.UtcNow);
executeThread.Abort();
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
public void Execute()
{
try
{
Library.LogData("Started");
while (true)
{
Library.LogData("Logging Execute" + DateTime.UtcNow);
Thread.Sleep(5000);
}
}
catch (Exception e)
{
Library.LogData("Error : " + DateTime.UtcNow + " " + e.Message);
OnStop();
}
Library.LogData("Out of Execute" + DateTime.UtcNow);

Logging code called by windows service
public static class Library
{
public static void LogData(string Message)
{
StreamWriter sw = null;
GetData getData = new GetData();
var dataClasslist = new List<DataClass>
{
new DataClass {}
};
try
{
dataClasslist = getData.ReadData();
using (sw = new StreamWriter("E:\\DataLogs\\LogFile.csv", true))
using (var csv = new CsvWriter(sw))
{
csv.Configuration.RegisterClassMap<DataClassMap>();
csv.WriteHeader<DataClass>();
csv.Configuration.TrimHeaders = true;
csv.Configuration.HasHeaderRecord = false;
csv.WriteRecords(dataClasslist);
sw.Flush();
sw.Close();
}
}
catch (Exception e)
{
var err = new StreamWriter("E:\\DataLogs\\Errors", true);
err.WriteLine(DateTime.Now.ToString() + ": " + e.Message.ToString());
err.Flush();
err.Close();
}
}
}

Main windows service
public partial class Service1 : ServiceBase
{
private Thread executeThread;
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
try
{
Thread.Sleep(10000);
executeThread = new Thread(new ThreadStart(Execute));
executeThread.Start();
}
catch (Exception e)
{
var err = new StreamWriter("E:\\DataLogs\\Errors", true);
err.WriteLine(DateTime.Now.ToString() + " OnStart: " + e.Message.ToString());
err.Flush();
err.Close();
OnStop();
}
}
protected override void OnStop()
{
try
{
executeThread.Abort();
}
catch (Exception e)
{
var err = new StreamWriter("E:\\DataLogs\\Errors", true);
err.WriteLine(DateTime.Now.ToString() + "OnStop exception: " + e.Message.ToString());
err.Flush();
err.Close();
}
}
public void Execute()
{
try
{
StreamWriter sw = null;
string FileNameAndPath = null;
FileNameAndPath = "E:\\DataLogs\\LogFile" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".csv";
using (sw = new StreamWriter(FileNameAndPath, true))
{
sw.WriteLine("TimeStamp " + "," + "col1" + "," + "col2" + "," + "col3"
+ "," + "col4" + "," + "col5" + "," + "col6" + ","
+ "col8" + "," + "col9" + "," + "col7" + "," + "col10");
sw.Flush();
sw.Close();
}
while (true)
{
Library.LogData(FileNameAndPath);
Thread.Sleep(5000);
}
}
catch (Exception e)
{
var err = new StreamWriter("E:\\DataLogs\\Errors", true);
err.WriteLine(DateTime.Now.ToString() + " Execute: " + e.Message.ToString());
err.Flush();
err.Close();
OnStop();
}
}
public void TestInConsole(string[] args)
{
Console.WriteLine("Starting.....");
this.OnStart(args);
}
So OnExecute will be called as soon as file hits 100kb and new file will be created with headers written in it only once.
public static class Library
{
public static void LogData(string FileNameAndPath)
{
StreamWriter sw = null;
GetData getData = new GetData();
var dataClasslist = new List<DataClass>
{
new DataClass {}
};
try
{
//System.Diagnostics.Debugger.Break();
dataClasslist = getData.ReadData();
//Create a file seperately
using (sw = new StreamWriter(FileNameAndPath, true))
using (var csv = new CsvWriter(sw))
{
csv.Configuration.RegisterClassMap<DataClassMap>();
//csv.WriteHeader<DataClass>();
csv.Configuration.TrimHeaders = true;
csv.Configuration.HasHeaderRecord = false;
csv.WriteRecords(dataClasslist);
sw.Flush();
sw.Close();
}
var FileSize = new FileInfo(FileNameAndPath);
//for each 1000 kb
if (FileSize.Length >= 1e+6)
{
//go back to the start to create a new file and column headers
Service1 serive1 = new Service1();
serive1.Execute();
}
}
catch (Exception e)
{
var err = new StreamWriter("E:\\DataLogs\\Errors", true);
err.WriteLine(DateTime.Now.ToString() + " LogData: " + e.Message.ToString());
err.Flush();
err.Close();
}
}
}
Im open for suggests, please let me know if you can thing of a better way to to do this.

Unable to start Windows Service if reference is used

I have create a windows service. when i try to start the service, i recieve the error

sw.WriteLine(Message);
}
}
else
{
using (StreamWriter sw = File.AppendText(filepath))
{
sw.WriteLine(Message);
}
}
}
}
}
But if i remove the lines
using Drone.Engine;
The service is starting successfully. Why am i unable to use it in the service?
The dll is present in the same directory. I have used the release build for installing. Still this issue.

Previously i was using filepaths like
filePath=#"data\log";
This was working fine in my application. But when i reference it to my windows service, i was getting System.IO.DirectoryNotFoundException error.
I changed the filepath to
filepath=AppDomain.CurrentDomain.BaseDirectory + "\\data\\logs";
It worked for both my service and application.

Try to launch an application from another application continue to crash

I wrote a program in C # that takes, from a WPF interface, a folder path, a prefix, and a prefix of substitution. The purpose of the program is to search in the folder all the files that start with the prefix and rename them with the new prefix. This program works without any problems.
Now I have to write a second program that must call the previous, passing the parameters using args []. I wrote this second program, it seems that all the parameters have passed correctly to the other (I checked it), but every time the replacement program runs out after a few seconds (while the normal run in my folder of Trial is almost instantly). I'm not able to have any message error or exception, I can only obtain the windows alert message that reports the crash.
Here is the significant part of the code of both programs ... Can anyone help me to find the problem? Is it a problem with settings passed from one program to another? Thanks a lot to everyone.
Can it maybe be a problem about the setting parameters of the calling?

_serialPort.Write(message + "\x1A");
Thread.Sleep(1000);
labelStatus.Text = "Status: Message sent";
_serialPort.Close();
}
}
}
Here's a link http://circuitfreak.blogspot.com/2013/03/c-programming-sending-sms-using-at.html

Why dont you open the port connection in the form_load() itself, later you can close it at the end as you did.
And do these too in Form_Load():
string cmd = "AT";
port.WriteLine(cmd + "\r");
port.Write(cmd + "\r");
port.WriteLine("AT+CMGF=1");
And simplifying the sms sending code:
port.WriteLine("AT+CMGS=\"" + PhNumber + "\"");
port.Write(Message + char.ConvertFromUtf32(26));

Try it this way.. You are not opening the connection to the serial port. I have tried it and it is working fine for me.
private void button1_Click(object sender, EventArgs e)
{
this.serialPort = new SerialPort();
this.serialPort.PortName = "COM5";
this.serialPort.BaudRate = 9600;
this.serialPort.Parity = Parity.None;
this.serialPort.DataBits = 8;
this.serialPort.StopBits = StopBits.One;
this.serialPort.Handshake = Handshake.RequestToSend;
this.serialPort.DtrEnable = true;
this.serialPort.RtsEnable = true;
this.serialPort.NewLine = System.Environment.NewLine;
serialPort.Open();
send_sms();

String messageToSend = null;
if (SMSMessage.Length <= 160)
{
messageToSend = SMSMessage;
}
else
{
messageToSend = SMSMessage.Substring(0, 160);
}
if (serialPort.IsOpen)
{
this.serialPort.WriteLine(#"AT" + (char)(13));
Thread.Sleep(200);
this.serialPort.WriteLine("AT+CMGF=1" + (char)(13));

this.serialPort.WriteLine(SMSMessage + (char)(26));
return true;
