Group List And Get A Count Of The Number Of Occurrences Sorted Descending
Feb 8, 2011
I have a list of ids properly stored in a List<>. I now need to Group list and get a count of the number of occurrences sorted descending.
Example:
List<string> aryIDs = new List<string>;
aryIDs.Add("1234");
aryIDs.Add("4321");
aryIDs.Add("3214");
aryIDs.Add("1234");
aryIDs.Add("4321");
aryIDs.Add("1234");
Would Produce:
"1234", 3
"4321", 2
"3214", 1
This would be easy in TSQL, but I would like to avoid the server roundtrip, unnecessary tables, etc. if possible.

I tried so much working with this to get distinct Words and their count. I'm using ASP.NET 2.0. And i also googled so much.
1)Ex(String): The DOTNET is Very Cool! The Best.
2) Capture all the sequences like Space, FullStop, Question Mark, Exclamation, Apostrophe, New Line....(May be with RegEx?)
3)Split Words According to the above sequences
4)Get Distinct Words(Occurences) and their count based on the input string in 1st statement.
Desired O/P:
The - 2
DOTNET - 1
Is - 1
Very - 1
Cool - 1
Best - 1

When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

im hope i can make sense to this post cause i dont have an idea where to begin :-) I have some files upload code so the user can upload files to the server (it can be 1 or 5 or 20 files). the code is working fine, and the files uploading to the folder on the server. The problem is, that after the files uploads i need to display to the user some textboxes to every file (like: number of copies, if its color or b/w, the print size etc). is there some way, after the files is uploaded, to show the user the name of the files and for each file name to display some textboxes (like: to count the number of files and then display the names and few same textboxes for each file),

Using Microsoft built-in jquery files, when counting numbers of checked checkbox, the jquery-1.4.2.min.js cannot count the correct result ,however, the version jquery-1.3.2.min.js gives out the correct one, why?
$("#check").click(function () {
var nameSports = new Array();
var i = 0;
$('input[name=selector]:checked').each(function () {
nameSports[i] = jQuery(this).val();
i += 1;
});
if (loopCounter != 0) {
alert(i);
}
});
<input type="checkbox" value="1" name="selector">
<input type="checkbox" value="2" name="selector">
<input type="checkbox" value="3" name="selector">
<a id="check">Check Items</a>

I would like to know the number of users logged into my ASP.NET 2.0 application.
Points to be considered:
1) Simplest way would be to use Application or Cache object to have the counts on Session start or end. However this would fail if there is a worker process recycle. Wouldn't it?
2) Should't make a difference whether the session is inproc/state server managed/ or SQL server managed.
3) Should preferably be seamless to a web-farm architecture.
