My code for splitting the strings is working however, i still need to use the splitted string my page. How can i achieve this? Here's my current code
private void SplitStrings()
{
List<string> listvalues = new List<string>();
listvalues = (List<string>)Session["mylist"];[code].....
how can i replace the response.write with any label or literal? when i tried to use a literal on the code it displays one single string not all of the strings that's been splitted.
I did a small experiment to test whether lamdba expression can retrieve faster results than foreach statement. but, Lambda failed
[Code]....
why lambda is slower than foreach. This may be a drawback of lambda expression
I want to show each item Id that is doing now dynamically in a foreach statement.
But the following code only shows the last item Id in Label1.Text.
How to show Label1.Text for each item in a foreach statement?
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
.
protected void Button1_Click(object sender, EventArgs e)
{
List<int> list = new List<int>()
{
1,2,3,4,5
};
foreach (var item in list)
{
Label1.Text = string.Format("I'm doing item {0} now.", item.ToString());
Thread.Sleep(1 * 1000);
}
}
I'm close to the solution I see where I am going wrong just unsure how to approach it. I want to be able to take a tables worth of data (via DataClasses) and put it in a CSV to download.
A LINQ to SQL query is performed (basically a 'Select All' from tbl_Newsletter), takes those results and the idea is to feed those results, one by one through the foreach which, inside it, is the CSV's definition e.g. List.Add(etc) as you'll see. After which the CSVExporter method is called - which works, as I can Download it, it just wont display any results.
C#: [Code]....
To which I get: Compiler Error Message: CS1729: 'Newsletter' does not contain a constructor that takes '2' arguments
with Newsletter obj = Newsletter.GetAll(); in place of Newsletter obj = new Newsletter();
I get: Compiler Error Message: CS0029: Cannot implicitly convert type 'System.Collections.Generic.List<Newsletter>' to 'Newsletter'

View 2 RepliesI've done some SSIS package work in the past, but am by no means an expert.
I want to use an SSIS package to do the following:
1. Get the file name of the newest file in a windows folder (using a filename template like his: filename_ *.txt where the * part is always a date in the format of yyyy-mm-dd.
2. Use that file name in later portions of the SSIS package by reading the file and transferring data from it to a SQL table using a Data Flow task.
and use the result (which should be the name of the newest file) to open that file and pull data out of it and into a 2nd SQL table. I admit, I'm not sure how to use the dynamic result of this SELECT query as the file name in a flat file connection manager.
I am rather confused as how or where to declare this variable in asp.net.

How would you handle an INSERT that gets some values from another table using SELECT, where you wanted some values to come from the source table record and other values to come from a different parameter source like a session value? Is this possible?

I don't know if I'm posting this in the right place - I have a feeling it can't be too difficult but I can't seem to figure it out. I've come across this problem many times and I've never solved it. I would imagine the scenario is commonplace - I have a table of Products with a PK of ProductID, and a table of related images with a FK of ProductID. Each product can have many images, but for my initial display I want to display one product record with one image record. I have a Sequence field in the Images table and I could pick the lowest one. Right and left Joins return too many records - if I have three images for Product 1 then Product 1 is listed three times.
I've gotten around this before using a flag in the Products table, or listing an image in both tables but I'm sure there must be a SQL statement that can get the information that I need.
I am currently trying to create a SQL statement that does a multiple count on a table. The table has a number of reports each listing the "User" who created that report and if that report is "Famous" (A famous report is symbolised as 2 in the table).
What I need to create is a SQL statement that returns each User with the total number of reports he/she has created and how many of these reports are famous. My current SQL statement looks like:

I have a method to execute two "Update" sql statements.
The first one works fine and the second one I can't get to work for nothing.
Here is the entire method:
[Code]....
The error I am getting is "Incorrect syntax near '05'."
It is occuring on the next to the last line which is:
dc.ExecuteCommand(sql);
I update the variable "sql" first so I can debug. At the time it crashes the value of sql is:
"Update Blogs set Status = 'Archived', ArchiveDate = 06/22/2010 05:14:46 PM Where (BlogID != 1) and (Status = 'Published') and (AuthorID = 9e37e028-c205-4903-920e-e8643b30a724)"
It appears to be the ArchiveDate that is causing the problem here. The "05" is the hour of the time portion. Both ArcgiveDate and PublishDate are defined exactly the same in the database. If you look at the first dc.ExecuteCommand it does exactly the same
thing with PublishDate (DateTime column) in the same table and it works just fine.
Then I modifed the code and remove the ArchiveDate from the sql statement then I get the error:
"Incorrect syntax near 'e028'."
which as you can see is part of the AuthorIDs value in the where clause. So I am assuming both the date and the Guid / Author ID is causing problems. I have tried enclosing the values in quotes but I just cant make this work even though it seems to be working fine in other places.
I even remove the code for the author ID and left in the code for the ArchiveDate and it still does not work so I have proved that both are causing a problem.
i have the followng code:

How do I insert the selections made on several checkboxes into the WHERE clause of a SQL SELECT statement? The scenario is as follows: the user selects one or more checks in different check boxes to determine the rows to be parsed in a SQL table. Then the user clicks on a Submit button and the result fills a Repeater table. How do I do this, and how do I configure the button to launch the SelectCommand?
