We have a webservice which stores data in sql server 2008R2.I am trying to build a billing system and struggling with the next sql query.

Am I going to be able to query (using LINQ to SQL) a database field with a type like the following "public System.Nullable<System.DateTime> Spouse_DOB"?
I'm trying to use the following code: [Code]....
and I get the error "'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)"
Is it because this DateTime column allows a NULL value (since everyone isn't married in my database)?
Error 1 'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)

My problem is: The GridView normally fits the grid perfectly to the data so that each cell only spans one row and has the appropriate column widths. However, when I add a row of TextBoxes to the bottom of this grid, the column widths suddenly all become equal, so that some cells with lots of words span multiple rows. Is there anyway to prevent this?
View 4 RepliesI'm using a linq group by query (with two grouping parameters) and would like to use the resulting data in a nested repeater.
var dateGroups = from row in data.AsEnumerable()
group row by new { StartDate = row["StartDate"], EndDate = row["EndDate"] };
"data" is a DataTable from an SqlDataAdapter-filled DataSet. "dateGroups" is used in the parent repeater, and I can access the group keys using Eval("key.StartDate") and Eval("key.EndDate").
Since dateGroups actually contains all the data rows grouped neatly by Start/End date, I'd like to access those rows to display the data in a child repeater. To what would I set the child repeater's DataSource? I have tried every expression in markup I could think of; I think the problem is that I'm trying to access an anonymous member (and I don't know how.) In case it doesn't turn out to be obvious, what would be the expression to access the elements in each iteration of the child repeater? Is there an expression that would let me set the DataSource in the markup, or will it have to be in the codebehind on some event in the parent repeater?

About Us
I'm working on a portal, and I need to check users conection on the ldap.
And if users are members of a special group then it works.
I've exactly used this link to make it works : http://msdn.microsoft.com/en-us/library/ff649227.aspx (almost work)
My point is : my ldap path seems good, no error anymore, when I log with my username and password.But when I querry it, it returns null, but I'm sure my user is in the group :
// Bind to the native AdsObject to force authentication. Object obj = entry.NativeObject; DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(SAMAccountName=" + username + ")"; search.PropertiesToLoad.Add("cn"); SearchResult result = search.FindOne(); if(null == result) { return false; }
I'm a normal user, i test with my account. I'm a member of the group that I'm looking for.
I am using below code to get new inserted ID in auto identity column from database.

View 2 RepliesI am using SQL Server 2005. I have below table:
CompanyNo CompanyName Product
--------------------------------------------------------
100 C1 P11
100 C1 P12
100 C1 P13
200 C2 P21
200 C2 P22
etc...
And I want my sproc returns like...
CompanyData
------------------
100 - C1 - P11, P12, P13
200 - C2 - P21, P22
etc...
I am trying to translate this:
SELECT IDNum, Max(Convert(varchar(20), (TimeOut - TimeIn), 108))
FROM IO_Times Group by IDNum
order by Max(Convert(varchar(20), (TimeOut - TimeIn), 108)) desc";
Into LINQ in C#. The above returns a list of the maximum value of (TimeOut-TimeIn) that corresponds to each unique IDNum (There are multiple TimeOut-TimeIn values for every IDNum).Here is what I am trying now:
from IO_Time in db.IO_Times
orderby SqlMethods.DateDiffMinute(IO_Time.TimeIn, IO_Time.TimeOut) descending
group IO_Time by IO_Time.IDNum into list
select new
{
ID = list.Key,
Time = list
});
This returns the correct IDs in the correct order, but the "list" contains everything in the database entry (which makes sense). I have also tried group by IDNum and Time, but then I get unique time entries and multiple IDs returned.I could do a foreach loop and manually sort it all out, but I would really rather not do that.
I want to be able to add a parent column header to each pair of columns shown below.
So I want it to look like this:
Grand Total
OnHand Available
Anyone know a way to do this? I know you can group columns together but I'm wondering how I can apply a label to those groups.
Alternatively, if theres no way to do that, I could just override the "Grand Total" display text. The only problem is I can't get it aligned above its correct columns.
I have a dataset like this:
BidID....DistributionMonth....LbsRemaining
1...........08-2010.................50,000
1........... 09-2010................25,000
1............10-2010................25,000
1............11-2010................100,000
I have a report that shows this data by pivoting on the month and giving the remaining amount, like this:
BID......Aug-2010 Remaining........Sep-2010 Remaining.......Oct-2010 Remaining........Nov-2010 Remaining
1..........50,000...............................25,000...........................25,000..............................100,000
This all works just fine. However now, I want to take a date that's given, and make a "Past Due" column for anything less than the first of the month of that date.
I'm currently learning entity framework (from the Julia Lerman book "Programming Entity Framework") and got really confused at the grouping part.
var contacts = from c in context.Contacts
group c by c.Title into myGroup
select myGroup;
This is supposed to return a Grouping<K,T> type, but the book didn't give an example on how exactly do I access this "contacts" query and I can't figure it out. When I did foreach(var contact in contacts), my "contact' variable has no knowledge of any of the properties of the Contact type (contact.FirstName etc).
i have the following objects:
Event:
- EventID (PK)
- GroupID (FK)
- StartDate
Group:
- GroupID (PK)
- GroupName
What i need to do is select the last 5 events for each group using LINQ to Objects. I tried starting with:
[Code]....
But i'm not sure how i only take the last 5 per group.
The simple way of doing this is to get the groups and then have a property on that which returns the last 5 events but if i databind this i will have to use a nested Repeater/ListView. Ideally i would like to have a row foreach event.
I have a table in sql having a numeric data type column,Now i want that whenever user left this field blank from front end aspx page, null value should be inserted in this column from stored proc.How can i achieve this?

I have a DIV element...
<div id="loginBox"> ... some other HTML elements inside here ... </div>
I use CSS to style this DIV and its contents....
#loginBox { ... }
#loginBox input[type="text"] { ... }
#loginBox button { ... }
... and so on ...
Now, I use a master page and the #loginBox DIV is inside the .master file.
At one point, I have the need to access the #loginBox at the server-side, so I add add runat="server" attribute. But as a result, ASP.net will change the ID of the DIV to #ct100_loginBox, and all the CSS code mentioned above.
I want to fetch date from a datetime field, when i select this field in database i get the result as 'yyyy-mm-dd hh:mm:ss' i want the result to be like dd/mm/yyyy
I am developing website using ASP.net C# using Mysql.query i have made is:
//***to get next date
string nextdatequery = "SELECT next_dt
FROM testcase.heardt where fil_no=?
and next_dt>?;";
Consider this snippet of code:
string sDate = string.Format("{0:u}", this.Date);
Conn.Open();
Command.CommandText = "INSERT INTO TRADES VALUES(" + """ + this.Date + """ + "," +this.ATR + "," + """ + this.BIAS + """ + ")";
Command.ExecuteNonQuery();
Note the "this.Date" part of the command. Now Date is an abject of type DateTime of C# environment, the DB doesnt store it(somewhere in SQLite forum, it was written that ADO.NET wrapper automatically converts DateTime type to ISO1806 format)
But instead of this.Date when I use sDate (shown in the first line) then it stores properly.
My probem actually doesnt end here. Even if I use "sDate", I have to retrieve it through a query. And that is creating the problem
Any query of this format
SELECT * FROM <Table_Name> WHERE DATES = "YYYY-MM-DD"
returns nothing, whereas replacing '=' with '>' or '<' returns right results.
So my point is:
How do I query for Date variables from SQLite Database.
And if there is a problem with the way I stored it (i.e non 1806 compliant), then how do I make it compliant
