I have absolutely no idea what to do with this but here is a snippet of the file that I'm trying to convert:
"September
3Beef
Lamb Chops
4Fish
Not Fish
5Mac and Cheese
PB & J"
The csv file is supposed to print the date what comes after in quotes, so the above should look like:
Tuesday September Third 2013 "Beef" "Lamb Chops"
Wednesday September Fourth 2013 "Fish" "Not Fish"
Thursday September Fifth 2013 "Mac and Cheese" "PB&J"
Here is what I have so far:
StreamReader reader = new StreamReader(#"..\..\Lunches.txt");
while (!reader.EndOfStream)
{
string currentLine = reader.ReadLine();
}
StreamWriter writer = new StreamWriter(#"..\..\Lunches.csv");
// date.ToString("ddddd yyyyy mm MMMMMM");
string delimiter = ",";
Here is the code
private void Form1_Load(object sender, EventArgs e)
{
string sayka = "August\n\n" +
"31Beef\n" +
"Lamb Chops\n" +
"24Fish\n" +
"Not Fish\n" +
"15Mac and Cheese\n" +
"PB & J\n";
MessageBox.Show(makeCSV(sayka));

From the filestream either use StreamReader.readToEnd(), get the string and use the function, Or if the file is big then use it line by line..

This is going to be a bit complicated. I left out some things for you to do.
String[] months = { "January", "February", "March", ....};
Date processDate = new Date();
while (!reader.EndOfStream)
{
string currentLine = reader.ReadLine();
// skip this line if blank
if (String.IsNullOrEmpty(currentLine)) continue;
if (months.Contains(currentLine)) {
// we have a new starting month.
// reset the process date
Int32 month = DateTime.ParseExact(currentLine.Trim(), "MMMM", CultureInfo.CurrentCulture).Month;
date = Convert.ToDate(month.ToString() + "/01/2013");
continue;
}
// here's where the real fun begins:
// you have to pull out the first two characters and test if one or both are digits.
// This will give you the day. Put that into your date variable.
Int32 day = 0;
char[] arr = currentLine.ToCharArray(0, currentLine.Length);
if (Char.IsDigit(arr[1])) {
// first two characters are numbers
day = Convert.ToInt32(currentLine.Substring(0,2));
currentLine = currentLine.Remove(0,2);
} else {
// only the first character is a number
day = Convert.ToInt32(currentLine.Substring(0,1));
currentLine = currentLine.Remove(0,1);
}
// set the new date
date = new DateTime(date.Year, date.Month, day, 0, 0, 0);
// If we can assume that ALL lines are broken into two parts then we can do the following:
String secondLine = reader.ReadLine();
currentLine = String.Format("{0} {1}", currentLine, secondLine);
// At this point you have the month, day, and the entire line.
// write it to your lunch stream or store in a StringBuilder

Edited the code and tried running the script. The logic written for SELECTPCRFROM is working fine but the same logic is not working for SELECTPCRTO. tried many others solutions but still SELECTPCRTO is nor working as expected Please help me on this. The executed code is displaying error message provided in the title
Most of the datepickers gets identified by xpath but when you try perform an operation on them then they would give you an error. Instead try going the javascript way.
Java -
document.evaluate(PATH, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
Similary you can use it in C#

Form contains two Textboxes (textBox1 and textBox2) and a Button(button1).
I want to type an amount in numbers in textBox1 and click on the button. The amount entered in numbers in textBox1 has to be converted to text and appear in textbox2. Functions to convert are in above C# class file. I am a new student. Can anyone help me in solving this problem.
You have to create an object for 'NumberToEnglish' Class and use it in Form1.cs this way
public partial class Form1 : Form
{
NumberToEnglish neObj = new NumberToEnglish();
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
textBox2.Text = neObj.changeCurrencyToWords(Convert.ToDouble(textBox1.Text));
}
}
public partial class Form1 : Form
{
NumberToEnglish Obj = new NumberToEnglish();
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
textBox2.Text = Obj.changeCurrencyToWords(textBox1.Text);//As your method accept a string..
}
}
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True" OnTextChanged="TextBox1_TextChanged"></asp:TextBox><br />
<br />
<asp:TextBox ID="TextBox2" runat="server" Height="100px" TextMode="MultiLine" Width="600px"></asp:TextBox>
</div>
</form>
And my code behind code is:
public String changeToWords(String numb)
{
String val = "", wholeNo = numb, points = "", andStr = "", pointStr = "";
String endStr = ("");
try
{
int decimalPlace = numb.IndexOf(".");

points = numb.Substring(decimalPlace + 1);
if (Convert.ToInt32(points) > 0)
{
andStr = ("point");// just to separate whole numbers from points/Rupees
}
}

Is there any other method that is faster than doing like this?
private void EscapeStringSequence(ref string data)
{
data = data.Replace("\\", "\\\\"); // Backslash
data = data.Replace("\r", "\\r"); // Carriage return
data = data.Replace("\n", "\\n"); // New Line
data = data.Replace("\a", "\\a"); // Vertical tab
data = data.Replace("\b", "\\b"); // Backspace
data = data.Replace("\f", "\\f"); // Formfeed
data = data.Replace("\t", "\\t"); // Horizontal tab
data = data.Replace("\v", "\\v"); // Vertical tab
data = data.Replace("\"", "\\\""); // Double quotation mark
data = data.Replace("'", "\\'"); // Single quotation mark
}
-- Edited (Add explanation) --
Q1: Is there a reason why you need to speed it up? Is it causing a huge problem?
This part is used in this project: http://mysqlbackuprestore.codeplex.com/
I'm going to loop lots of various length of strings into this function repeatly. The whole process takes around 6-15 seconds to finished for millions of rows. There are other part get involve too. I'm trying to speed up every part.
Q2: How slow is it now?
OK, I'll capture the exact time used and post it here. I'll come back later. (will post the result tomorrow)

Try using a series of StringBuilder calls.
I can written an application which converts strings (made of numbers) from 8 - 12 characters in length (see examples below)
1404336133
4174728823
0587035281
Basically I want to convert the strings above into a specific format (stored in a config file) for the time being its as shown below.
<add key="Consumer_Code_Format_For_Code_Length_Eight" value="#### ####"/>
<add key="Consumer_Code_Format_For_Code_Length_Nine" value="### ### ###"/>
<add key="Consumer_Code_Format_For_Code_Length_Ten" value="### #### ###"/>
<add key="Consumer_Code_Format_For_Code_Length_Eleven" value="#### ### ###"/>
<add key="Consumer_Code_Format_For_Code_Length_Twelve" value="#### #### ####"/>
I am currently using the following code to format the codes ...
public static string FormatCode(string code)
{
switch (code.Length.ToString())
{
case "8":
string codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Eight"];
code = String.Format("{0:" + codeFormat + "}", Double.Parse(code));
break;
case "9":
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Nine"];
code = String.Format("{0:" + codeFormat + "}", Double.Parse(code));
break;
case "10":
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Ten"];
code = String.Format("{0:" + codeFormat + "}", Double.Parse(code));
break;
case "11":
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Eleven"];
code = String.Format("{0:" + codeFormat + "}", Double.Parse(code));
break;
case "12":
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Twelve"];
code = String.Format("{0:" + codeFormat + "}", Double.Parse(code));
break;
default:
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Eight"];
code = String.Format("{0:" + codeFormat + "}", Double.Parse(code));
break;
}
// Finally return the newly formatted code
return code;
}
However, for the code 0587035281 it displays "58 7035 281" therefore removing the leading zero which I require.
Any ideas how to stop this and also is there anything wrong or suspicious with my code?
Looking forward to your reply
public static string FormatCode(string code)
{
switch (code.Length.ToString())
{
case "8":
string codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Eight"];
break;
case "9":
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Nine"];
break;
case "10":
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Ten"];
break;
case "11":
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Eleven"];
break;
case "12":
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Twelve"];
break;
default:
codeFormat = ConfigurationManager.AppSettings["Consumer_Code_Format_For_Code_Length_Eight"];
break;
}
char[] result = new char[codeformat.Length];
int used = 0;
for(i = 0; i < codeformat.Length; i++)
{
if (codeformat[i] == '#')
{
result[i] = code[used];
used++;
}
else
result[i] = codeformat[i];
}
// Finally return the newly formatted code
return new string(result);
}
Doublevalues are actually stored as numbers, so leading zeroes are being automatically removed when using Double.Parse().
Tho add the nleading zeroes once again, you can do something similar to this (not tested, written from the top of my head.) Remember the original length, then compare the result and add as many leading zeroes as required.
public static string FormatCode(string code)
{
int originalLength = code.Length;
switch (originalLength)
{
case 8:
string codeFormat = ...;
code = ...;
break;
case 9:
codeFormat = ...;
code = ...;
break;
// ...
while (code.Length < originalLength) {
code = "0" + code;
}
return code;
}
There's no pretty solution you can do inline, you'll have to do your own processing. Since this is not really a number you're dealing with, and maybe you may need to have some non-numeric literals there, best that you just insert a space every N characters. This would go something like this:
int chunkSize = 3;
string a = "0123456789";
int len = a.Length;
StringBuilder sb = new StringBuilder(len + len / chunkSize);
int firstIdx = len % chunkSize;
sb.Append(a.Substring(0, firstIdx));
sb.Append(" ");
for (int i = firstIdx; i < len; i += chunkSize)
{
sb.Append(a.Substring(i, chunkSize));
sb.Append(" ");
}
a = sb.ToString();
