Web Forms :: How To Avoid Data Class Duplicates
Jan 7, 2010I have several LINQ-auto-created data classes which are created using dragging and dropping database tables into the Visual Studio LINQ design pane. Also, in my project I have to manually create WCF data-contract classes. Each WCF contract class is for one LINQ-auto-created data classes; one to one. Is there some better way to reduce the efforts to this problem? e.g. inheritance or something else to create WCF datacontract class from existing LINQ-data class.
Example:

DataSource Controls :: Can Pull A Top Record And Avoid Duplicates
Feb 3, 2010I have location #s, date, time, the sales amount, and tax in a excel file. The system pulls sales numbers throughout the day from each store location and places the total sales and tax numbers along with the polling date into a file.
So the most current date/time has the most upto date sales numbers at the time for that location number, but it also lists the older entries so mgmt can see how sales went during the day, and this is where my issue is, I don't need to see the old numbers from this generated file (atleast at this part of the program).
What I would like to do is write a query that only selects the most recent sales numbers for each location. I will output this to a table in ASP.NET. The query I tried using the TOP 1 clause only gave me the very first row listed below.

C# - Counting Occurrences Of A String In An Array And Then Removing Duplicates?
Jan 2, 2010I 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

How To Remove Duplicates From A List In C#
May 3, 2010I 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:
List<Dictionary<string, object>> result = val.Distinct().ToList<Dictionary<string, object>>()
Update: Problem is now solved. I used the MySQL union command to read table from the database.
Hit Insert Several Times And Got Duplicates?
Dec 10, 2010I have a simple asp.net web forms page that does an insert to my sql server db. My server was running slow at the time and I pressed Insert button several times because I didn't think it took but it did all 3 times.So I have duplicates from that one interaction.

SQL Server :: How To Union Two Queries Without Duplicates
Aug 27, 2010I 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:

SQL Server :: Insert Date And No Duplicates
Oct 8, 2010I am importing images names from a file into a database by using the code below. When I import the image names, I aslo want to add a date of "June 12, 2009" in the DATE column.

.net - CssClass Duplicates On An UpdatePanel Update?
Apr 20, 2010I'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"
Web Forms :: Remove Duplicates From List Method?
Nov 16, 2010I have a Method that returns 4 records like this.
Name: Test1
Year: 2010
Value: $1000
Name: Test2
Year: 2010
Value: $1000
Name: Test3
Year: 2011
Value: $2000
Name: Test4
Year: 2011
Value: $1000
I need a way to get the unique years just ( 2010, 2011) rather than all 4 years, rest of the data could be duplicates.
Here is the method:
public List<TestCosts> GetTestvalues(string testid)
{
List<TestCosts> testlist = Testscores.List(testid);
return testlist;
}
Most of the examples of removing duplicates I saw have a list of one item only but in my case I have 3 items per record and I need to loop through each record, find the duplicate years, remove them and then return the distinct list of years along with the other data.
Building An Import Process That Checks For Duplicates?
Dec 1, 2010Using ASP.NET, I'm building an admin tool that requires a function to import a list of email addresses. Upon uploading the file, I want to check for existing records for any of the email addresses supplied. For non-existing email addresses, I would create them using my DAO.
Basically I want to:
Receive list of emails
Retrieve data for existing emails
Create data for new emails in db
Return full data for all emails in list.
Since I want to know which of the emails exist up front, my first thought was to query the table for all records WHERE Email IN ('Email001FromFile', 'Email002FromFile', 'etc...') but the list could potentially contain thousands of email addresses, and I'm not certain supplying that many email addresses to the IN operator would be a good idea.
I also thought about looping through the list and checking for a record for each email, but that would potentially generate far too many queries.
My next thought was to generate a temp table to hold the list and modify the IN clause to use the temp table, rather than an explicit list of items, but that would require I execute SQL or a stored procedure directly, which I'm not inclined to do since I'm using NHibernate to access my DB.
Though I am using ASP.NET (C#) and NHibernate

DataSource Controls :: Identifying Duplicates In Data Upload?
Mar 3, 2011Using SQL server and C# to build my web site. I need to do a bulk upload Employee data from Excel to SQL.
I use the following code to perform this. The code works fine.
[Code]....
In the Employee table there is a field called ID which is of type int and auto incrememntral . This is the primary key.
There cannot be duplicates in the combination of EmployeeName and Location. If the user tries to upload ( through the Excel file) the combination of EmployeeName and Location which is there in the database, I need to flag it.
How can I identify the duplicates in an easy way rather than going through all the records again and again? Any functaion in SQL I can use to identify the duplicates?
C# - Bind The Values Without Duplicates From Database Into Dropdown Using LINQ?
Apr 2, 2011I have a small issue binding the values into a dropdown using LINQ in ASP.NET code-behind.
var clientquer = from i in Entity.New_Bank select i;
//var q = (from s in names
// select s).Distinct();
// var getlendername = (from db in mortgageentity.New_Lender group db by db.Bank_Name into t select t.Key).ToList();
if (clientquer.Count() > 0)
{
ddlbankname.DataSource = clientquer.ToList();
ddlbankname.DataValueField = "Bank_ID2";
ddlbankname.DataTextField = "Bank_Name";
ddlbankname.DataBind();
}
It is binding with duplicate values, but I don't want bind duplicate values. I'm trying to solve this by using a group by clause, but it is not working.
