Opening a file and using the string within

When I open a file (I made myself) I need to use somethings out of the string of text that comes trough. I want to use some parts of the text as coordinates to draw a graph with.
private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
char XgetalEen;
char XgetalTwee;
char YgetalEen;
char Ygetaltwee;
string XgetalSamen = "";
string YgetalSamen = "";
int coordinaatX;
int coordinaatY;
DialogResult lel = MessageBox.Show("Do you want to close this file?", "OPEN", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
if (lel == DialogResult.Yes)
{
Open();
foreach(string s in Gcowde)
{
XgetalEen = s[5];
XgetalTwee = s[6];
YgetalEen = s[8];
Ygetaltwee = s[9];
XgetalSamen += XgetalEen + XgetalTwee;
YgetalSamen += YgetalEen + Ygetaltwee;
if(XgetalTwee==' ')
{
XgetalSamen = "";
XgetalTwee = '0';
XgetalSamen += XgetalTwee + XgetalEen;
YgetalEen = s[7];
Ygetaltwee = s[8];
YgetalSamen = "";
YgetalSamen += YgetalEen + Ygetaltwee;
}
if(Ygetaltwee==' ')
{
Ygetaltwee = '0';
YgetalSamen = "";
YgetalSamen += Ygetaltwee + YgetalEen;
}
MessageBox.Show(XgetalSamen + " " + YgetalSamen);
Int32.TryParse(XgetalSamen, out coordinaatX);
Int32.TryParse(YgetalSamen, out coordinaatY);
currentLocation.X += coordinaatX;
currentLocation.Y += coordinaatY;
Coord.Add(new Point(currentLocation.X, currentLocation.Y));
}
drawerryting();
}
}
public void Open()
{
Gcowde.Clear();
listBox1.Items.Clear();
Coord.Clear();
werkVlak.Clear(Color.Black);
Coord.Add(new Point(pictureBox1.Width / 2, pictureBox1.Height / 2));
drawerryting();
OpenFileDialog openFileDialog1 = new OpenFileDialog();
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
StreamReader sr = new StreamReader(openFileDialog1.FileName);
string errything = sr.ReadToEnd();
string charAdded = "";
foreach (char s in errything)
{
if (s == '\n')
{
Gcowde.Add(charAdded);
charAdded = "";
}
else
{
charAdded += s;
}
}
foreach (string s in Gcowde)
{
listBox1.Items.Add(s);
}
sr.Close();
}
This is the code how I open the file and get the coordinates out of the string. The string is of this kind L1 G2 X50 Y50. i need to get the 2 50s out of the string.
ps.: the variables are in dutch.
XgetalEen = XnumberOne, XgetalTwee=XnumberTwo,
same goes for Y.
XgetalSamen=XnumberTogether, YgetalSamen=YnumberTogether.

This is a simple example how you could parse the file:
// Read your file using File.ReadAllLines
String[] lines = new[] { "L1 G2 X50 Y50", "L1 G2 X50 Y50" };
foreach (var line in lines)
{
String[] values = line.Split(' ');
string x = values.Where(s => s.StartsWith("X")).First().Replace("X", String.Empty);
int xCoordinate = Convert.ToInt32(x);
}
Don't forget to add all necessary checks and reading of other variables.

i want to select numeric values only...but it fetch alphabets as well..
i want to select only numeric values from HTML and using [0-9]* as regular expression, but its not working and show alphabets as well. i want only numeric values, what is correct regular expression? any idea??

Here you go, what you're looking for are Grouping Constructs:

}
int j = 0;
for (int i = 0; i < mclName.Count; i++)
{

string name = mclName[i].Groups[1].ToString();
if (i == 0 || i == 4)
{

New line in C# for Word Document

how to recognize new line c# while uploading word documents..? i have to give next line as a new word in word document here what is happening means if i add three or more words in .doc in separate line its taking as one word i want to separate the words but if i give a space after a word it is taking as expected without giving space if i start a new word in new line its taking as one word
money
power
cash
moneypowercash
like this iam getting here if i give space after these words its getting as expected
how to resolve this issue here i will give my code to generating this keyword
protected void btnSubmit_Click(object sender, EventArgs e)
{
try
{
if (cmbDepartment.SelectedValue != "0" && cmbDocumentType.SelectedValue != "0")
{
TodayDate = DateTime.Today.ToString("yyyy-MM-dd");

using (reader)

}
//remove common words

}
string str = Keywords.ToString();

Keywords.Append("<words><s>" + str.Replace(" ", "</s><s>") + "</s></words>");
string xml = Keywords.ToString();
XElement items = XElement.Parse(xml);
var groups = from t in items.Descendants("s")
group t by t.Value.ToLower() into g
select new KeyFrequency(g.Key, g.Count());
groups = groups.OrderByDescending(g => g.Frequency).Take(15);
keyvalues = new List<string>();
foreach (KeyFrequency g in groups)
{
keyvalues.Add(g.Key);
}
for (key = 0; key < keyvalues.Count && key < 10; key++)
{
Button btn = (Button)pnlKeywords.FindControl("Button" + Convert.ToString(key + 1));
btn.Visible = true;
btn.Text = keyvalues[key];
btn.CommandArgument = keyvalues[key];
}
if (key < 10)
{
for (key = key; key < 10; key++)
{
Button btn = (Button)pnlKeywords.FindControl("Button" + Convert.ToString(key + 1));

}
}
else
{

}
}
}
catch (Exception ex)

For each new line, try replacing \n with "</w:t><w:br/><w:t>". It worked for me.
string.Replace("\n", "</w:t><w:br/><w:t>")

System.Data.OleDb.OleDbException(0x80004005): Unspecified Error

Through a series of loops and Database calls (Select statements only) saved as datatables I am generating a .txt file with the values. It runs fine for a little while (19 rows...19 full loop cycles) then I get a runtime exception being thrown by connection.Open()
I have the entire loop inside a try catch block in order to catch the exception and produce the message then 2 blank lines then the stack trace.
I have tried to read this and figure out what to do but I am a bit of a Novice when it comes to DB connections. I have looked elsewhere but do not seem to find a question that quite fits my situation.
FYI: C# 4.0 Windows Form Application, Access DB
I am hoping to find some suggestions on where to begin looking. I am positive that my connection is closed when this error is thrown due to the validation i implemented as shown here:
internal IDbConnection GetConnection()
{
try
{
var connection = _assemblyProvider.Factory.CreateConnection();
connection.ConnectionString = _connectionString;
_connectionState = connection.State.ToString();
if (_connectionState == "Open")
GetConnection();
else
{
connection.Open();
}
return connection;
}
catch (Exception exept)
{
throw new Exception(exept.ToString() + "\n\n" + exept.StackTrace.ToString());
}
}
This method is being called from here:
public DataTable ExecuteDataTable(string commandText, string tableName, DbParameterCollection paramCollection, CommandType commandType)
{
DataTable dtReturn;
IDbConnection connection = null;
try
{
connection = _connectionManager.GetConnection();
dtReturn = _dbAdapterManager.GetDataTable(commandText, paramCollection, connection, tableName, commandType);
}
finally
{
if (connection != null)
{
connection.Close();
connection.Dispose();
}
}
return dtReturn;
}
public DataTable ExecuteDataTable(string commandText, string tableName, CommandType commandType)
{
return ExecuteDataTable(commandText, tableName, new DbParameterCollection(), commandType);
}
public DataTable ExecuteDataTable(string commandText)
{
return ExecuteDataTable(commandText, string.Empty, CommandType.Text);
}
and
//read from DB using a SQL statement and return a DataTable
internal static DataTable readDB(string SQL)
{
var dbHelper = new DbHelper();
using (IDbConnection connection = dbHelper.GetConnObject())
{
return dbHelper.ExecuteDataTable(SQL);
}
}
Here is the loop (its kinda long and could probably be done better but I just want to find why its breaking after its worked several times)
The exception is thrown from the line that Reads:

After looking deeper into the code I realized that the connection was trying to open 3 times before it closed. Not sure why I was not getting exceptions all the time but correcting this issue not only sped up the application tremendously it cleared the exception.

Serial Port reads fine but assigned string has junk, C#

I am trying to split the incoming data from a Serial Port, and update text boxes with subsequent data. I first see if a split on '$' is possible, and if the next word after splitting is "GPGGA". If yes, I would like to extract data from this sentence where ',' serves as the separator.
Now, as you see, I update the entire data read by the Serial Port first, and this works fine. The full sentence containing the "GPGGA" line is displayed. But after I split it, the part of the sentence that contains the "GPGGA" looks something like this"GPGGA,1\0\0\0\0\0..." when really the sentence that was just updated to the text box before was "GPGGA,160333,,,......". I am absolutely certain that there is a value after GPGGA in the sentence but when i try to look at it in the debug mode, the string 'ser_data', and hence its subsequent substrings all show the same junk. So, the final text box that I want to update inevitably ends up displaying just 1.
Could anyone tell me why this is happening, and how I can correct it. I need it urgently for my thesis work.
Thanks,
Brett

SerialPort.Read does not necessarily read the number of characters you ask for.
You need to save the return value, which is the number of characters read.
// nBytesRead will be between 0 and 40, depending on how many bytes were waiting.
int nBytesRead = serialPort.Read(bData, 0, 40);
// Only decode the number of bytes actually retrieved.
string ser_data = System.Text.Encoding.GetEncoding("utf-8").GetString(bData, 0, nBytesRead);

Fixed and majorly cleaned up. This assumes two things: that your encoding is really UTF-8, and that your lines end with newline characters.
private void serialPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
serialPort.Encoding = ASCIIEncoding.UTF8;
string ser_data = serialPort.ReadLine();
txtAck.Invoke(new UpdateTextCallback(this.UpdateTextAck), new object[] { ser_data });
