When I try to remove the last few characters of a string, I get an index out of range error. I am using the following to remove the characters from the end of the string: objJSONStringBuilder.Remove(objJSONStringBuilder.Length - 1, 6) The string has <hr /> at the end which I want to remove.
View 3 Repliesi have a problem in string manipulation
here is the code
string str = "LDAP://company.com/OU=MyOU1 Control,DC=MyCompany,DC=com";
Regex regex = new Regex("OU=\w+");
var result = regex.Matches(str);
var strList = new List<string>();
foreach (var item in result)
{
strList.Add(item.ToString().Remove(0,3));
}
Console.WriteLine(string.Join("/",strList));
the result i am getting is "MyOU1" instead of getting "MyOU1 Control"
I have a string
it contains can contains either of (1) strQuery = "TempTable.Group_No IN ()";
(2) strQuery = "TempTable.Group_No IN (1,2,3,4,....)";
My task is if it contains "TempTable.Group_No IN ()", (i.e) IN CLAUSE without data i have to replace the string (IN() with IN (NULL)) with "TempTable.Group_No IN (NULL)"
I need to dynamically modify the contents of a column in a GridView1 before it is displayed. Basically, I need to convert every 'Environment.NewLine' in a field to a so it displays as a new line on an ASP.NET page. How do I do this?
View 2 RepliesI store some values from code behind to a label which is Hidden !
<asp:Label ID="lbl_Hidden" runat="server" Visible = "false"></asp:Label>
and at the page load event i retrieve the value of the label & assign it to a string !
stringvalue = lbl_Hidden.Text;
Now i dont know why this manipulation does'nt work! I've a character 'A' in the string and i'm unable to replace it with a space ! stringvalue.Replace(A, " ");
If I have a file in a path lke this:
C:demo estfile.txt
I can a split function and split on the backslash character to get the pieces. But if my directory could change this wouldn't work. So how would I instead parse out the last backslash and get the filename that way so that it wouldn't matter if the path changed?
I wrote a small .NET applications that removes all line breaks in aspx/html/css code to make it harder to read for people trying to steal my design. And surprisingly I get weird characters that appear out of nowhere such as Â, » and others. They all stay at the same places, but I have no clue why they appear.
View 2 RepliesI have a string with 100 characters and it is for me too long in one line. I want to make NewLine after each 25 characters. For example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
I am having the doubt in string manipulation. I am having the following string value string input="(Grade=A && Standard='12')||(City='ABC' || Region='India')&& (Name=='John')"; I would like to do the precedence condtion so that i want to split the above string in the followung form to identify the precedence group.
Grade=A && Standard='12' --arr(0)
|| --arr(1)
City='ABC' || Region='India' --arr(2)
&& --arr(3)
Name=='John' --arr(4)
I have the following text, I need to extract the exception name and the continuing sentence from the file, but the file has continuous sentences without a space.

I need to extract the following keywords: ConnectException, javanetConnectException and any exception as well as its exception type.
I want to dynamically populate a link with the URI of the current request, but set one specific query string parameter. All other querystring paramaters (if there are any) should be left untouched. Eg, imagine I want to build a link back to the current page, but with the querystring parameter "valueOfInterest" always set to be "wibble" (I'm doing this from the code-behind of an aspx page, .Net 3.5 in C# FWIW).Eg, a request for either of these two:
/somepage.aspx
/somepage.aspx?valueOfInterest=sausages
would become:
/somepage.aspx?valueOfInterest=wibble
And most importantly (perhaps) a request for:
/somepage.aspx?boring=something
/somepage.aspx?boring=something&valueOfInterest=sausages
would preserve the boring params to become:
/somepage.aspx?boring=something&valueOfInterest=wibble
Caveats: I'd like to avoid string manipulation if there's something more elegant in asp.net that is more robust. However if there isn't something more elegant, so be it. I've done (a little) homework: I found a blog post which suggested copying the request into a local HttpRequest object, but that still has a read-only collection for the querystring params. I've also had a look at using a URI object, but that doesn't seem to have a querystring
I want to show just a part of a string for example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
Just a: "Lorem ipsum dolor sit amet, consetetur sadipscing..."
Which method can I use to do that?
I am accumulating a string for a SQL IN clause, so the format needs to be WHERE var IN ('string1','string2','string3',etc)
The strings are coming from a multiline textbox where they are pasted in from the user (one per line).
For some reason, I always get a space right after the tick and before the value in every value after the first. For instance my DataReader is only returning one record because the input string turns out like this:
SELECT * FROM Table
WHERE ID IN ('12345',' 23456',' 34567')
Here is how I am processing the string, and I can't see why it is not taking that space out.
[Code]....
Even if I move the replace space (line 2) to the end of the code block, it still wont trim it out...
I am fairly new to C# programming and I am stuck on my little ASP.NET project.
My website currently examines Twitter statuses for URLs and then adds those URLs to an array, all via a regular expression pattern matching procedure. Clearly more than one person will update a with a specific URL so I do not want to list duplicates, and I want to count the number of times a particular URL is mentioned in, say, 100 tweets.
Now I have a List<String> which I can sort so that all duplicate URLs are next to each other. I was under the impression that I could compare list[i] with list[i+1] and if they match, for a counter to be added to (count++), and if they don't match, then for the URL and the count value to be added to a new array, assuming that this is the end of the duplicates.
This would remove duplicates and give me a count of the number of occurrences for each URL. At the moment, what I have is not working, and I do not know why (like I say, I am not very experienced with it all).
With the code below, assume that a JSON feed has been searched for using a keyword into srchResponse.results. The results with URLs in them get added to sList, a string List type, which contains only the URLs, not the message as a whole.
I want to put one of each URL (no duplicates), a count integer (to string) for the number of occurrences of a URL, and the username, message, and user image URL all into my jagged array called 'urls[100][]'. I have made the array 100 rows long to make sure everything can fit but generally, this is too big. Each 'row' will have 5 elements in them.
The debugger gets stuck on the line: if (sList[i] == sList[i + 1]) which is the crux of my idea, so clearly the logic is not working.
Here is sample code:
var sList = new ArrayList();
string[][] urls = new string[100][];
int ctr = 0;
int j = 1;
foreach (Result res in srchResponse.results)
{
string content = res.text;
string pattern = @"((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\))+[wd:#@%/;$()~_?+-=\.&]*)";
MatchCollection matches = Regex.Matches(content, pattern);
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
sList.Add(groups[0].Value.ToString());
}
}
sList.Sort();
foreach (Result res in srchResponse.results)
{
for (int i = 0; i < 100; i++)
{
if (sList[i] == sList[i + 1])
{
j++;
}
else
{
urls[ctr][0] = sList[i].ToString();
urls[ctr][1] = j.ToString();
urls[ctr][2] = res.text;
urls[ctr][3] = res.from_user;
urls[ctr][4] = res.profile_image_url;
ctr++;
j = 1;
}
}
}
The code then goes on to add each result into a StringBuilder method with the HTML.Is now edite
I am looking for a better way to update a list of records. I have a string column in my table that contains an array of strings like so:"11112,AAAA1,AAAA2,99998" etc. It is possible that the column could contain one of those values at any position, for instance, these are ALL valid values for the column:
"11112"
"AAAA1,11112"
"11112,AAAA1"
"AAAA1,11112,AAAA2"
I want to write a SQL statement that will remove "11112" from all of the columns when needed. This MUST also remove any leading, trailing, or double comma values that may be left from simply replacing the "11112" with an empty string.As of now, I simply load a SqlDataReader with any records that contain "11112", I replace it with nothing, "", then I fix the string if need be and update it.
i have string
Dim str As String = "C#app_wiod_200"
i want to remove characters from wiod in string which one is the best string function to do this.
I've got a program that in a nutshell reads values from a SQL database and writes them to a tab-delimited text file.
The issue is that some of the values in the database have special characters (TM, dash, ellipsis, etc.) When written to the text file, the formatting is lost and they come across as junk "â„¢ or â€" etc"
When the value is viewed in the immediate window, before it is written to the txt file, everything looks fine. My guess is that this is an issue of encoding. But, I'm not real sure how to proceed, where to look, or what to look for.
Is this ASCII or UTF-8? If it's one of those how do I correct it before it's written to the text file.
Here's how I build the text file (where feedStr is a StringBuilder)
objReader = New StreamWriter(filePath)
objReader.Write(feedStr)
objReader.Close()
i have a string and want to remove text up to the last forward slash, e.g
/images/UserThumbnails/22.jpg
Should now be
22.jpg
How do i go about doing this?
I'm currently working on this application that records a users email.
I was wondering if there was a function that would read the last 7 digits of the inputted user email and store it in a variable? Is there any way to do this?
I need to be able to sort by a product title and then by a products price, which is simple but I only want the title sorted on the first 3 or 4 characters. My client wants to add the brand name to the beginning of the product title and have them automatically sorted. I can a new field in the database called brand and sort by that, but wanted to know if this is possible. I've posted what I though might work but it doesn't

I guess this is probably possible with a lambda expression, but I've no experience with Lambda expressions at all.
I want to display description of product in gridview, but i want to display only 15 characters on one line, I want to break it after 15 characters, I have written countchar function as follows:
public int CountChars(string value)
{
bool lastWasSpace = false;
foreach (char c in value)
{
result++;
lastWasSpace = false;
}
return result;
}
and called function as:
string description="sdfsdfsd sdfsdf sdfsdf asdfsa dfsda safsaf sdfdf sdfs sdfsdf sdff sdf ";
CountChars(description);
And i want to check:
if(result>15)
{
after every 15 characters i want to break the line.
}

View 4 Repliesusing vb.net/asp.net 2005 and sql server 2005. I'm querying the database and returning text which I am then adding to a string. I'm creating a crystal report with the text however this is not a crystal report question, its about the string data. what I"m noticing is that when I show the string on the pdf that there are some strange characters at the end of the string. I am both trimming the string and taking out null characters however the strange text shows up like this:
strangeText>
SÙÇ
TÙçy|Ü
DÙÇ
$ÛÇ
</strangeText>
does anyone know what these characters are and how to get rid of them?
