My team working asp.net File manage project. In our project we need to export database contents to csv formats
The Database table contains 6 fields. We are using LINQ.

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);

I was able to successfully get the Excel export function working but there are issues with the CSV I am still troubleshooting.
My issue is this though. I have a Gridview of both English and other foreign languages such as Japanese and Thai. The foreign Asian languages do not export properly using your code. European languages such as Spanish, French and Italian have no problem. Do you have a fix to support the Asian languages?
I'm running a query that brings millions of records and makes the server run out of memory. I'm thinking I should get the data in chunks. So I was wondering if someone could shed some light on this or point me to another place where I can read further.
Currently, I just implemented "paging". I can now pass a "page index" parameter and "page size". So I could call 1,000 times the stored procedure with a page size of 1,000 (for 1 million records). This might be an option, but I wanted to hear someone else's opinion on how to "stream" records from oracle to the web server and then to a file.
The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.
All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.
So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?
I have a table 'articles' where all the articles are stored and I want to create a search engine for my website.
user types the keywords in the search engine and what code i should use to search the records in my database?
my requirement is that SSRS 2005 report should show all records with checkboxes(or can be by any other means of flagging ?) .
Now the records for which checkboxes are checked or flagged are only to be included in the exported excel sheet or pdf .

I have a table which stores records about a promotion programs. For each record, there are different status such as Begin, Successful, Unsucessful, Expired and there are PromotionDate and PromotionExpiredDate. I am just wondering how I can set each promotion to auto expired (auto change the status of each promotion status to Expired) when the current date is bigger than the PromotionExpiredDate.

View 1 RepliesI created web pages that used an SQL database on my home computer. That DB allowed me to use data types such as 'date' and 'time'. But when I transferred my website to a host server, I discovered that its DB does not accept these types. They only use 'datetime' and 'timestamp'. I changed the tables in the DB on my computer to conform to the same format as on the host computer. I also changed the properties to the new data types with the O/R Developer and re-published the website files to the host server. But I keep getting the same error message that states the server does not support 'date' data types whenever I execute a web page that uses that table column. The C# code states "officetable.StartDate = DateTime.Today;"
View 2 RepliesI would like to create a database where users can search for multiple fields. For example: if the record is personal details info like name, address, phone number and email id i would like to generate link for this automatically with the fields using stored procedure.. Is that possible.? If so can anybody provide me with the line of code or guideline on how to do that?
View 3 RepliesI get the same culture i.e. "en-US" while running the website from both IIS and Visual Studio's web server.
But I get a different date format as follows, when I run the following code:
HttpContext.Current.Response.Write(System.Threading.Thread.CurrentThread.CurrentCulture.ToString());
HttpContext.Current.Response.Write(System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern);
On Visual Studio's web server: dd/MM/yyyy en-US
On IIS: M/d/yyyy en-US
Does "Regional and Language Options" in "Control Panel" play any role in this ? If I change the date format there in "Regional and Language Options", I see no effect in my application.
I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.
View 4 RepliesI have a issue where I am trying to pull some records from an Access 2007 DB that has linked tables from a SQL 2005 Server. When I go to do this the browser IE8 just sits there and does nothing. THe little progress bar at the bottom moves about half way then that is it. It will sit there and show no errors or do anything. I have experience with connecting and manipulating Access and SQL server DB's but not through Access with linked tables from SQL Server. Here is test code below:

This does not produce an error or anything. The browser just sits there and sits there. Is there something I am missing?

I originally, I used most of the code from this link: URL....to allow our users the ability to check one or more checkboxes, grab data from the checked boxes and append them into a url.This works a treat.Here is code snippet.
Protected Sub btnGetChecked_Click(ByVal sender As Object, ByVal e As EventArgs)
Response.AddHeader("content-disposition", "attachment; filename=Parcels.pdf")
HttpContext.Current.Response.ContentType = "application/pdf"
Dim doc As New PdfDocument()
[Code] .....
Above code was based on link above.Then our users were having problem preserving checked boxes when navigating to other pages since we are using paging.Then I was fortunate to your article for preserving checkboxes from the link below: URL...Does anyone know how to modify it to use new code from this link?My guess is that it needs to be modified to work with the following code but I am not sure what to change.
For i As Integer = 0 To GridView1.Rows.Count - 1

.FindControl("CheckBox1"), CheckBox)
