Sorting excel sheets c# || how to exclude lines that are missing a specific cell

I am currently working on a windows forms app using c# that will be able to convert Pastel Partner trial balances to Pastel Evolution compatible balances.
I am trying to implement code that will skip all lines in the sheet that do not have account codes (col 2)
Please assist with a code example on how to do this, it would be highly appreciated!
The excel sheet needs to convert from this (Partner)...
To this (Evolution)...
This is my form and code so far...

{
public partial class Form1 : Form
{
public string date; // set by user
public string codeDate; // set by date and OB string
public string OB = "OB"; // set value
public string zero = "0"; // set value
public string accCode; // needs to be read from the first excell sheet and printed with a ">"
public string contraCode = "9990>001"; // set value
public bool credCheck = false; // bool that is interactive
public bool debCheck = false; // bool that is interactive depending on whether the account is in credit or debit
public string fileName = ""; // set from the openFileDialog
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e) // lets user select csv file.
{
openFileDialog1.ShowDialog();
openFileDialog1.Filter = "CSV Files (L*.csv)|L*.csv"; // Filters to only .csv files
fileName = openFileDialog1.FileName;
if(openFileDialog1.ShowDialog() == DialogResult.OK)
{
lblFileName.Text = openFileDialog1.FileName; // prints file directory
}
}
public static string[] ReadCSV(string searchTerm , string filePath , int positionOfSearch)
{
positionOfSearch--; // moves over by 1 (more understandable)
string[] recordNotFound = { " Record Not Found " }; // array for errors
try
{
string[] lines = System.IO.File.ReadAllLines(#filePath);
for (int i = 0; i < lines.Length; i++)
{
string[] fields = lines[i].Split(',');
if (recordMatches(searchTerm , fields , positionOfSearch))
{
return fields;
}
}
return recordNotFound;
}
catch(Exception ex)
{
Console.WriteLine("error");
return recordNotFound;
throw new ApplicationException("Error : ", ex);
}
}
public static bool recordMatches(string searchTerm , string[] record , int positionOfSearch)
{
if (record[positionOfSearch] != " ")
{
return true;
}
return false;
}
private void btnConvert_Click(object sender, EventArgs e)
{
DateTime tempDate = dateTimePicker1.Value;
codeDate = "OB " + tempDate.ToString("dd/MM/yyyy");
date = tempDate.ToString("dd/MM/yyyy");
}
}
}

If the account codes are in col 2, then you can check for empty values in the loop which you already have
string[] fields = lines[i].Split(',');
if (fields[1] != "") <-- check if account code is an empty string
{
if (recordMatches(searchTerm , fields , positionOfSearch))
{

Adding Page Numbers

I haven't really written anything outside of Powershell in a long time, and I know this is ugly, but I can't seem to figure out why my new PDF is not adding the page numbers. I pulled the example from this itext kb.
I tried to make this basic app so people in the office could add the page numbers to PDF's. Here's what I have so far. It will create the new PDF (duplicate of the original), but it's not adding the page numbers.
Basically they use button1 to find their PDF via the Windows File Explorer dialog. It just stores the filename in a textbox. The second button is the "save" and should take the src file and make a copy of the src with only adding the page number at the bottom of the file (or anywhere at this point).

}
private void button1_Click(object sender, EventArgs e)
{
int size = -1;
DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog.
if (result == DialogResult.OK) // Test result.
{
string file = openFileDialog1.FileName;
try
{
string text = File.ReadAllText(file);
size = text.Length;
textBox1.Text = file;
}
catch (System.IO.IOException)
{
}
}
Console.WriteLine(size); // <-- Shows file size in debugging mode.
Console.WriteLine(result); // <-- For debugging use.
}
private void button2_Click(object sender, EventArgs e)
{
Stream myStream;
//SaveFileDialog saveFileDialog1 = new SaveFileDialog();
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if ((myStream = saveFileDialog1.OpenFile()) != null)
{
// Code to write the stream goes here.
myStream.Close();
string SRC = textBox1.Text;
string DEST = saveFileDialog1.FileName;
FileInfo file = new FileInfo(DEST);
file.Directory.Create();
PdfDocument pdfDoc = new PdfDocument(new PdfReader(SRC), new PdfWriter(DEST));
Document doc = new Document(pdfDoc);
int numberOfPages = pdfDoc.GetNumberOfPages();
for (int i = 1; i <= numberOfPages; i++)
{
// Write aligned text to the specified by parameters point
doc.ShowTextAligned(new Paragraph("page " + i + " of " + numberOfPages),559, 806, i, TextAlignment.CENTER, VerticalAlignment.TOP, 0);
}
doc.Close();
}
}
MessageBox.Show("PDF Page Numbering Added!", "Pages Added",MessageBoxButtons.OK);
Application.Exit();
}
}
}

I'm a dumb dumb. The x,y coordinates were off as the value 812 for the height is off the page.

C# RDLC Report Printing [duplicate]

I have an application where I have to print a RDLC report without showing the printDialog and using the default specified printer defined in the application. Below is my test implementaion code.
Microsoft.Reporting.WinForms.ReportViewer reportViewerSales = new Microsoft.Reporting.WinForms.ReportViewer();
Microsoft.Reporting.WinForms.ReportDataSource reportDataSourceSales = new Microsoft.Reporting.WinForms.ReportDataSource();
reportViewerSales.Reset();
reportViewerSales.LocalReport.ReportPath = #"Sales.rdlc";
reportDataSourceSales.Name = "SalesTableDataSet";
int i = 1;
foreach (Product item in ProductSalesList)
{
dataset.CurrentSales.AddCurrentSalesRow(i, item.Name, item.Quantity.ToString(), item.Price.ToString(), item.Price.ToString());
i++;
}
reportDataSourceSales.Value = dataset.CurrentSales;
reportViewerSales.LocalReport.DataSources.Add(reportDataSourceSales);
dataset.EndInit();
reportViewerSales.RefreshReport();
reportViewerSales.RenderingComplete += new RenderingCompleteEventHandler(PrintSales);
And here is my Rendering Complete Method
public void PrintSales(object sender, RenderingCompleteEventArgs e)
{
try
{
reportViewerSales.PrintDialog();
reportViewerSales.Clear();
reportViewerSales.LocalReport.ReleaseSandboxAppDomain();
}
catch (Exception ex)
{
}
}

I just gave a quick look to a class I created to print directly and I think I took some ideas from this walkthrough:
Printing a Local Report without Preview

i have made an extension class to #tezzos answer. which might make it more easier.
use this Gist Here to get the extension class i wrote. include it to your project. don't for get namespace :D
LocalReport report = new LocalReport();
report.ReportEmbeddedResource = "Your.Reports.Path.rdlc";
report.DataSources.Add(new ReportDataSource("DataSet1", getYourDatasource()));
report.PrintToPrinter();
PrintToPrinter Method will be available on LocalReport. Might Help someone

How can I get client PC Printer settings using C#, asp.net

I have SSRS report runnig on a web application. I want to print SSRS report data directly on the client's printer. The application works well in my pc but when I publish the application on IIS web server, instead of retrieving the printer settings of client pc, the application is trying to look for printers that are installed in the server machine.
I am using System.Drawing.Printing, Is there any way to get the settings of installed printer in the client computer or can we print SSRS reports from Web using C# ?
I am using following code.

You can use javascript function window.Print()
This will list you client machine printers and print your page.
Hope below code will help..try
<html>
<head>
<script>
function page()
{
window.print()
}
</script>
</head>
<body>
<input type="button" value="Print page" onclick="page()">
</body>
</html>
But this will print the whole page..in your case its a report to print
hope this link can guide you
print crystal report to client printer
print report to client default printer

While loop not breaking from signal given by the user in WPF (C#)

I have a WPF which executes a GUI for serial communication. I want to keep triggering the device and recoed the values till the user says stop. I have a global bool variable STOP which I set to false when user presses the stop which in turn should terminate the while loop which triggers the device continuously but the problem is that once the user selects the run button whcih runs the while loop, the WPF app freezes and doesn't accept the STOP button click.
Can someone give me an idea of what is happening here or a any suggestion on how to implement it differently.

You need to run your serial port code in separate thread. In your implementation GUI thread is busy w/ serial port communication that is why your window is frozen. The following article explains exactly what you need:
