Get values from one textbox and put them in another textboxes

I have values from a textbox :
"r, 00.00m,0000521135Hz,0000000000c,0000000.000s, 025.1C"
and I want to make each value show in another textboxes like this:
textbox 1:
a: "00.00"
textbox 2:
b: "0000521135"
textbox 3:
c: "0000000.000"
textbox 4:
d: "025.1"
I can do this in arduino using parseInt(),
I wonder how to do this in c#, any help?

you can use a string.split() function to extract value from first textbox.
string baseStr = "r, 00.00m,0000521135Hz,0000000000c,0000000.000s, 025.1C";
List<string> colStr= test.Split(new char[','], StringSplitOptions.RemoveEmptyEntries);
and then remove alphabet using regular expression
using System.Text.RegularExpressions;
...
Textbox1.Text = Regex.Replace(colStr[1], "[A-Za-z]", "");
Textbox2.Text = Regex.Replace(colStr[2], "[A-Za-z]", ""));
...

This will give you the idea how to put the data in the textboxes. I have done it for a string variable.
string s1 = "r, 00.00m,0000521135Hz,0000000000c,0000000.000s, 025.1C";
string[] spliteds1 = s1.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
string txt1 = "";
foreach(string elem in spliteds1)
{
if(Regex.Replace(elem, "[^0-9.]", "") != "")
{
txt1 = txt1 + Regex.Replace(elem, "[^0-9.]", "") + ",";
}
}
This code will put the in txt1 with comma seperator. You can run your loop for textboxes.
Hope this helps

RichTextBox not printing newline

I have this method that replaces(in bold) some words in a string and show the changed string in a ritchtextBox.
In the final string I need to replace the # symbol by a newline.
I already tried checked this forum tying several solutions, but nothing worked.
The method I use is
private string bold(string ing)
{
StringBuilder builder = new StringBuilder();
ing = " " + ing + " ";
builder.Append(#"{\rtf1\ansi");
foreach (string word in splitwords)
{
var regex = new Regex(#"(?<![\w])" + word + #"(?![\w])", RegexOptions.IgnoreCase);
ing = regex.Replace(ing, m => #"\b" + m.ToString() + #"\c0");
}
ing = ing.Replace(#"\b", #"\b ");
ing = ing.Replace(#"\c0", #" \b0");
ing = ing.Replace("#", Environment.NewLine);
builder.Append(ing);
builder.Append(#"}");
MessageBox.Show("builder.ToString():" + builder.ToString());
return builder.ToString();
}
When I call the this method and "put it" in the ritchTextBox it doesn´t print the new line
ingred.Rtf = bold(ingd);
How should I solve this??
EDIT:: input string - line1 # line2 # line3
output in the MessageBox
Builder.ToString() : {\rtf1\ansi\b line1\b0
line2
line3
}
output in the ritchTextBox: line1 line2 line3

Instead of
ing = ing.Replace("#", Environment.NewLine);
Try
ing = ing.Replace("#", #"\par\r\n");

Use This Code For Repalce
int startIndex = 0, index;
RichTextBox myRtb = new RichTextBox(); // if have A richtextBox Remove thisline and Use your Richtextbox
myRtb.Rtf = STRRTF;// if have A richtextBox Remove thisline and Use your Richtextbox
while ((index = myRtb.Text.IndexOf("#", startIndex)) != -1)
{
myRtb.Select(index, word.Length);
myRtb.SelectedText ="\n";
startIndex = index + 1;
}

Better use Environment.NewLine for adding new line also Make sure yourRTB.MultiLine property is set to true. assign string to richtext box like this yourRTB.AppendText(t)

Try replacing it with a "\r\n" character sequence?
edit: is MultiLine property of ritchtextBox enabled?

Find Chr(13) in a text and split them in C#

I have written two lines of code below in vb6. The code is :
d = InStr(s, data1, Chr(13), 1) ' Fine 13 keycode(Enter) form a text data.
sSplit2 = Split(g, Chr(32)) ' Split with 13 Keycode(Enter)
But I can't write above code in C#. Please help me out. How can I write the above code in C#.

I believe you are looking for string.Split:
string str = "Test string" + (char)13 + "some other string";
string[] splitted = str.Split((char)13);
Or you can use:
string[] splitted = str.Split('\r');
For the above you will get two strings in your splitted array.

the equivalnt code for sSplit2 = Split(g, Chr(32)) is
string[] sSplit2 = g.Split('\n');

int index = sourceStr.IndexOf((char)13);
String[] splittArr = sourceStr.Split((char)13);

const char CarriageReturn = (char)13;
string testString = "This is a test " + CarriageReturn + " string.";
//find first occurence of CarriageReturn
int index = testString.IndexOf(CarriageReturn);
//split according to CarriageReturn
string[] split = testString.Split(CarriageReturn);
If you want to encapsulate the carriage return depending on whether you are running in a unix or non unix environment you can use Environment.NewLine . See http://msdn.microsoft.com/en-us/library/system.environment.newline(v=vs.100).aspx .
string testString2 = "This is a test " + Environment.NewLine + " string.";
//find first occurence of Environment.NewLine
int index2 = testString2.IndexOf(Environment.NewLine);
//split according to Environment.NewLine
string[] split2 = testString2.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);

How to capture exact td value in jquery independent of browser

I have li inside it i contain td.
var values = '';
$("#list4 li.add table .mytd").each(function () {
values = $(this).html() + '|' + values;
});
document.getElementById("MainContent_uscRetailParameters_hdRetailCustomerGroup").value = values;
__doPostBack('<%=txtRCCode.ClientID%>', '');
when I capture in hidden field it come like this
[alot of spaces]CHARMINSENSITIVE-1
with lot of spaces how can i retrieve the exact value in all browser. this space not found in Internet explorer. but in firefox it comes with spaces how could i capture the exact td value.
string lvValues = hdProductGroup.Value;
//string trim = lvValues.Replace(" ", "");
string trim = lvValues.Replace("\r", "");
trim = trim.Replace("\r", "");
trim = trim.Replace("\n", "");
trim = trim.Replace("\t", "");
string str = trim;
string[] list = str.Split('|');

You could trim it in Jquery? Try something like the following:
values = $.trim($(this).html() + '|' + values);
Or at the server using something like:
value = value.Trim();

C# replace part of string but only exact matches possible?

I have a string beginString = "apple|fruitsapple|turnip";
What I want to do is replace just apple with mango, not fruitsapple.
string fixedString = beginString.Replace("apple","mango"); This doesn't work because it replaces both apple and fruitsapple.
Any ideas?

beginString = "|" + beginString + "|";
fixedString = beginString.Replace("|apple|","|mango|");

This cannot be done in the way you have said since it will consider the entire string to be a string. You can do the split by | as you have used or else have the strings in a list and use equals and then replace it.
String[] words = beginString.Split("|");
now do the replace on words. works for any scenario.

The variation on other answers in LINQ style:
string fixedString = string.Join("|",
beginString
.Split('|')
.Select(s => s != "apple" ? s : "mango"));

Closest I can get. Was gonna suggest regular expression, but that won't always work as you want. You have to split the string first and then remake it.
string searchString = "apple";
string newString = "mango";
string beginString = "apple|fruitsapple|turnip";
string[] array = beginString.Split('|');
foreach (var item in array)
{
if (item == searchString)
item.Replace(searchString, newString);
}
string recreated = "";
new List<string>(array).ForEach(e => recreated += e + "|");
recreated.TrimEnd('|');

string newstr = Regex.Replace("apple|fruitsapple|turnip", #"\bapple\b", "mango");
