I would like to develop an application which shows upcoming dates which is stored in database. I have a label control namelyNext Payment Date in which i want to store that upcoming date(next due date). Eg : if the value stored in db are :(dd/mm/yyyy) 22/12/2010, 15/12/2010,18/12/2010. and if todays date is 10/12/2010.. i want to display 15/12/2010 in that Next Payment Date label..
So how can i do this.using vb.net. what will be the SQL Query and how do i implement this
i wanat to display Client Name, Field and image in datalist. Stored Procedure like this

my table customer table contains attributes Name,age,email and address.i want to ask user to enter to his id to display his datas.
after he enterd his id each label will be assigned with the database values accordingly.i tried like above.couldnt get the output.
My problem is regarding title written above. Currently I have some functions that rely on Sessions to do the job. Everything works smoothly when it is left to default. However, I do not like the idea of losing sessions in case of crash and I have modified my web.config to use Sql Server mode instead.
I have run the necessary commands to create tables and stored procedures in my database using aspnet_sql.exe. I am able to store values into the database but have not been successful retrieving them. Since it has been working fine with InProc mode, I think I can safely assume that there's nothing wrong with my codes. Here's my web.config setting:
<sessionState mode="SQLServer" allowCustomSqlDatabase="true" cookieless="false" timeout="120" sqlCommandTimeout="30" compressionEnabled="true"
sqlConnectionString="Data Source=.SQLExpress;Initial Catalog=mytest;Persist Security Info=True;User ID=mytest;Password=mytest;"/>
If i have two textboxes textbox1 & textbox2 and button1 in my ASP.NET and SQL Server database
Database records are:
ID Date Seats
1 15-Dec-2010 1,2
2 15-Dec-2010 3,4
3 17-Dec-2010 1,2,3,4
I want when i type 15-Dec-2010 in TextBox1 and Click on Button1 then in textbox2 The Output would be retrieve from Database using SELECT query then in TextBox2 the output would be displayed as 1,2,3,4
That the exact i want using SELECT query and VB.NET.
I am working on Edit operation for dropdownlist box using linq to sql in asp.net mvc.During edit operation i could retrieve it from database but i am not able to restore the selected value back to the database.

What I have below is currently working on my site to display information within an article. What I am wondering is that within a lot of stories I have more than one 'SchoolID' included. All of these IDs are in our database within the 'ArticleSchool' table and linked to an 'ArticleID.' The statement below is only displaying the first 'SchoolID' listed within an article. Is there a way I would be able to display every 'SchoolID' within an article to grab information from? Will it not work in a label if there are multiple values? The 'ArticleSchool' table has rows for every article and a new instance if more than one 'SchoolID' is attached.

For example, the MS Customize CreateUserWizard walkthrough [URL] adds the ability to save the users preference for subscribing to a newsletter and allowing their info to be shared as 1 value in the comment column of the membership database. The result ofaspnet_Membership.Comment is Subscribe=TRUE&ShareInfo=FALSE.
My question is if Subscribe=TRUE&ShareInfo=FALSE is in one field of the database, how would you retrieve just the Subscribe=TRUE value from the field and use it to send a newsletter to the proper users while ignoring the ShareInfo=FALSE value?

I'm an experienced PHP programmer that is new to ASP.net (C#). I'm trying to figure out how to do a manual echo of a specific field from an SQL database and was wondering how you do an if condition in case the field would meet certain criteria ?
What I want the script to do is check in the database if a certain condition is activated, then the html page should echo a windows media player object with the source of the video coming from the database itself ( $line[Video], and if the condition isn't active then either don't echo the player or just echo an old video (in the script I'm just printing a message).
