--This column is the issue
,Governing_Class=( case when exists (select top 1 tqc.class_code from
t_quote_class tqc
inner join t_quote_class_premium tqcm on tqc.class_code =tqcm.
class_code
where tqc.appid=pi.appid and tqc.class_code not in('8742' ,'8810','7380')
order by tqcm.premium_amt desc
)
then ( select top 1 tqc.class_code from

I have to build a screen that tracks despatched goods on trucks on a certain date. I have created a form (using C# and ASP.NET) where I am displaying the calendar and am allowing the user to select the date he wants to check for the despatched goods.
My question is how to store the date that was clicked by a user in a variable which I want to use it later in an SQL query.
Should I store the date as a session variable? Suppose I want to display the date that the user clicked, how do I display it?

I have an aggregate stored procedure (named sp2) that returns a count of records meeting a certain criteria ASrecCount. I am using a DAL per the ASP.NET tutorial and have created a Table Adapter (named
sp2TableAdapter) with GetData and Fill methods. I have a button on an ASP.NET page that launches an event handler. In the button's event handler, I have this line: sp2TableAdapter sp2 = new sp2TableAdapter();
What works so far:
This code will bind the value of sp2 to a data control:
sp2TableAdapter sp2 = new sp2TableAdapter();
DropDownList1.DataSource = sp2.GetData();
DropDownList1.DataValueField = "recCount ";
DropDownList.DataTextField = "recCount";
DropDownList1.DataBind();
When running this page and clicking the button, the numeric value of recCount returned from sp2 is bound to the DropDownList control and 1 row is poplated with the recCount value (in my case 1451).
Problem:
In the event handler, I do not want to bind the value of recCount to a control, but want to to use it in some logic as an integer. What is the C# code that will do this? (In place of the DropDownList control lines above)

View 6 RepliesI have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.
I would like to run a SQL query on the codebehind VB page that will also set a value from that query to a Session variable. Also, this needs to be done on the Page_Load.
Example:
[Code]....
sales.aspx.vb
Custom function which stores the current DATE into todayDate. I use this function to convert system date into SQL friendly date.
sales.aspx
I used Data Grid and SQL Data source.
SelectCommand="select * from sales where aab = 110026"
I want my select statement should take the date from todayDate.
i.e.: SelectCommand="select * from sales where aab = todayDate"
How to write this statement in correct syntax.

I am attempting to do an insert query on a webpage for a simple member registration form I have created in vs2010. I have done this type of thing before without problem using an access database, but now I'm using a sqlexpress db created from within vs2010. This is the screenshot of my insert query:
Now, when I execute this query in the form, I get an error that says:
Must declare the scalar variable "@FirstName".Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

At first I just had my query with all ?'s instead of @FirstName, etc in the insert statement itself, but I got an error on that as well but it was different, it just said syntax error near "?" or something to that effect. If I manually perform this query in the builder, and it pops up a window that asks for values on everything, I put something into each field and the insert works great. It just won't work with these parameters for some reason. Can someone advise what I need to do?
I use the follwoing code to get a value from the SQL query. But now i would like to use some sql function like Sum() count() ... and i would like to get the result of that.
