I am using a ReportViewer control on a aspx page. It is using a dataset and one of the fields is Date. The dataset's source is an object datasource. User selects startdate/enddates and other params, they are given to the object datasource, the datasource returns all the rows using a stored procedure, so the dataset is now populated. But the dataset has just one date field.
My problem - I want to display the start date and end dates on the report header. Right now - it just keeps the last value (end date).
A table contains
startdate datetimeenddate datetimeClassHours nvarchar(30)SujectName nvarchar(40)TeacherName nvarchar(40)
I have 2 doubts
1# IN DATABASEstartdate enddate ClassHours Subject Name TeacherName10-05-2011 16-05-2011 11.00 A.M Chemistry Akbar
IN GRIDVIEW I WANT TO DISPLAY THIS AS

View 5 RepliesI am facing a big problem with simple linq query.. I am using EF 4.0..
I am trying to take all the records from a table using a linq query:
var result = context.tablename.select(x=>x);
This results in less rows than the normal sql query which is select * from tablename;
This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..
This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?

View 4 RepliesWhat is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.
Approaches I can think of (and their disadvantages):
1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?
2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.
3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.
How to start at a specific record and returning only the next 5 records with T-SQL command
[Code]....
That is my concatenated SQL statement but it obviously does not work because it only looks at the top 5 records in the entire table instead of what I intended which would be to look at the top 5 records starting with the record where PostNumber equals the value of lastPost. I have been searching for a T-SQL statement that will allow me to do this but I can't find one.

View 5 Replieswhere I'm going wrong with this SQL Query of an Access Database which populates a Datagrid,
From a calendar selection the user can select a From and To Date and I want the SQL Query to ONLY pick up the dates between these two values, the selection is fine it seems to be the sql query which is the problem ... (I have added dates rather than the text value to make it easier to get working ) the following query wil pick up dates outside of the selected values 01/08/2010 , 02/08/2010, etc
SELECT COUNT(*) AS Date_Installed, Date_Installed AS Expr1, Installed_By FROM Buildprocess WHERE (Date_Installed BETWEEN '20/08/2010' AND ' 25/08/2010') GROUP BY Date_Installed, Installed_By
how to get the start and end dates of the week by passing in a week number? I have a dropdownlist that needs to show 2010-05-17 - 2010-05-23 and I need to determine this date by passing in a week number.
Ex: if I pass the number 20, it will return 2010-05-10 - 2010-05-16 etc...
My dropdownlist will always only show one week and it will always be the previous week from the currect week.
I am using C# + VSTS 2008 + .Net + ASP.Net + IIS 7.0 + ADO.Net + SQL Server 2008. I have a ADO.Net datatable object, and I want to filter out duplicate/similar records (in my specific rule to judge whether records are duplicate/similar -- if record/row has the same value for a string column, I will treat them as duplicate/similar records), and only keep one of such duplicate/similar records.
The output needs to be a datatable, may output the same datatable object if filter operation could be operated on the same datatable object.
What is the most efficient solution?
I want to create an application where I need to enter date to the ms access database.
I am a bit confused regarding how to make the user to enter date. The options avaliable are:
a. Shall I use a textBox?
b. Shall I go for 3 drop down lists?
or something else.
Some more questions:
1. what date format shall i use? (dd-mm-yyyy, dd-mmm-yyyy, etc, etc or anything else)
2. What datatype shall i use to store the date in the database?
3. What SQL query shall i use to retrieve the data between 2 dates?
let me know if there are multiple options available regarding this application.
I want to make this application as easy as possible for the user.
Say If got these dates in a TextBox 2010/06/19,2010/06/20,2010/06/21,2010/06/22,2010/06/23, i want automicly my Start label to pickpup the lowest date and Label End to pickup the highest Date Start: [2010/06/19] End: [2010/06/23] between brackets is my label

I need some pointers to start on this.We are building a time off application where three instances of a calendar control will be displayed ( prev - current and next month) now users can click on various dates accross all three instances and then a count of number of days should be diaplyed in the parent textbox.
To begin with this, i started with adding the dates clicked by the user in Calendar2_SelectionChanged method into a list<> so that i can get the all dates user clicked and then add it to calander's selected dates collection. But this throws an e" object reference not set" error.
Is there anyother way to get all the dates that user click onthe calendar( note the dates doesn't get highlighed so seleteddates doesnt work)does anyone has a good example for this.
