Let say I have a string like this
Dim Mystring as String = "Dogs;cats;Dogs;apple;cars;dogs;cats"
I want to only find the values that is in the string more then once....and then create a new string
like Result Dim NEWstring as String = "Dogs;cats"
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:#@%/;$()~_?+-=\.&]*)";
MatchCollection matches = Regex.Matches(content, pattern);
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
sList.Add(groups[0].Value.ToString());
}
}
sList.Sort();
foreach (Result res in srchResponse.results)
{
for (int i = 0; i < 100; i++)
{
if (sList[i] == sList[i + 1])
{
j++;
}
else
{
urls[ctr][0] = sList[i].ToString();
urls[ctr][1] = j.ToString();
urls[ctr][2] = res.text;
urls[ctr][3] = res.from_user;
urls[ctr][4] = res.profile_image_url;
ctr++;
j = 1;
}
}
}
The code then goes on to add each result into a StringBuilder method with the HTML.Is now edite
I'm currently working on this application that records a users email.
I was wondering if there was a function that would read the last 7 digits of the inputted user email and store it in a variable? Is there any way to do this?
I am using a chat script I found for free online.
It allows a profanity filter by using string replace:
ex: ChatText.Replace("hell", "!@#$")
is there a way to do a wildcard replace? It doesn't catch the word "HELL" or "Hell" for example.

So below is my code but no string is written to that linkButton, so I wonder if I miss something basic out here?

For an MVC 2 app that relies on many partial views and almost exclusively uses Ajax for POSTs/GETs, what would be the best way to implement the setting, passing, retrieval and display (using a JavaScript modal) of these messages?
My forms all POST (by way of jQuery $.ajax) to actions that return partial views (html) that are used to update a in the "success:" part of the $.ajax function.
I was hoping for some sort of mechanism in the master view that could "listen" for any messages that any of these partial views might be "delivering"--through their ViewData, for instance.

View 9 Repliesi have list<player> with duplicates.
i need to create another list<player> from the first list <player> with out any duplicates.
My SQL query joins on multiple tables, and because of this it is displaying multiple results. I know about SELECT DISTINCT, but one of the fields ('Account.Name') is occasionally different, so it treats this record as a new row. Here is my SQL:

I have a code:

I want to remove duplicates from this list:
List<Dictionary<string, object>> val = new List<Dictionary<string, object>>();
It does not work if I apply Distinct() in this way:

I have a sql query that returns 4 columns CustName CustId CustZip CustPhone
I have a second sql query that returns the following 5 columns
CustName CustId CustZip CustEmail CustAddress
Both queries, query different data tables in the database, but return columns that are common to
both.
How do I union the two queries(Assuming a union is needed)
Which will result in no duplicates and an end result being the following output:
CustName CustId CustZip CustPhone CustEmail CustAddress
As you can see we want to not have duplicate values on output. So something like the following
is not acceptable:

I've got a simple user control in my ASP.NET Webforms project which inherits from the LinkButton. It's got a property to change the size, which just adds some predefined CSS classes to the control.
Protected Overrides Sub CreateChildControls()
Dim SizeClass As String = String.Empty
If Size = SizeEnum.Large Then
SizeClass = "large"
[Code]....
So when it renders the class property is something like class="button small".
When this control is placed inside an update panel along with some other things, when the update panel updates the class property for every one of these controls becomes class=" button small button small button small button small button small button small button small button small button small button small button small button small button small"
