I am creating roombooking website in asp.net.
and i am facing problem while inserting the record.
eg:
if the room is already booked from 1st march 2010 to 10th march 2010.and if anybody is booking the same room from 4th march to 9th march it should show error message stating that
this room is already booked from 1st march to 10th march.
On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value.
Then if user will provide some other telephone number then he allows to insert record.
For insertion of record I used ObjectdataSource.
User will enter telephone number in a simple textbox.
I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit.
I have a formview and inside it there are two textboxes taking integer as input.I put a condition that if both textboxes are empty then user should be notified that "Please put value in any one of the textbox".It is working very fine.From database side DBA checked that if user input any integer value in any one of the two textboxes and if it is already found in database then there is no insertion.The problem is that everything is working fine and i checked in the database that the record is also not inerting due to duplicate check but user is getting message that "Record inserted successfully."How to stop this message and how to notify user that you have entered duplicate value and transaction should also not been done. Means all inputs should be there rather than clearing textboxes that could be done when "Record Inserted."

View 1 RepliesI have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate records?

I want to select dates that also fallin the range. Heres the scenario: I have an event from 01/20/2010 TO 01/25/2010. So right now it would only return a date of 01/20/2010. How could I return 01/20/2010, 01/21/2010 , 01/22/2010, 01/23/2010, 01/24/2010, 01/25/2010? Mind you only a start and end date are in the database.
I have a requirement that i need to select the multiple date range.like if i select the date 21 to 26 , in that case i dont want to deselect the date in between. the funcanolity i saw in the [URL] web site where you fill the parameter and according to that parameter you find the calander.
View 2 RepliesI am creating an album using the following stored procedure, which returns the primary key for the newly created record:
SET ANSI_NULLS ON

CREATE PROCEDURE [dbo].[fpa_sp_albums_update_insert]
@album_id int,

However, the createdAlbumID always shows -1 instead of the id for the newly created album.
Say I have a table called "Visits", and I want to create a query that counts the visits per day. The way I would accomplish this would be to create a query as such:
SELECT Count(VisitId) as VisitCount, Convert(varchar(32), VisitDateTime, 101) as VisitDate
FROM Visits
WHERE VisitDateTime BETWEEN '10/1/2010' AND '10/5/2010'
GROUP BY VisitDate
The problem I am trying to overcome is that if there were no visits in a given day, that day does not show in my list. For example, if there were 3 visits on the 1st, 2 on the 2nd, none on the 3rd, and 5 on the 4th, my result set would look like:
3, 10/1/2010
2, 10/2/2010
4, 10/4/2010
How can I create my query so that I get all days in the date range listed in the result set regardless of whether the VisitCount is zero?
I want to have auto-generated date from 24-10-2014 to today in gridview column...
View 1 RepliesThis must be easier than this: I want to highlight a range of dates, in this case: All dates after today. The only control I can see which allows me to wire-in to a date based X-Axis is the Stripline So, I get today's date minus my earliest date in the dataset in days... No problems. So to set up the Stripline I try something like:
[Code]....
and ends up looking like: Today is where the second shade begins. This is fine, but it is looping over 12 months. The number of days since it began is 399 days. I was hoping that would have actually meant the offset was 399 days. Am I trying too hard with the wrong class? Is there something else I should be using?
my ddl1 and ddl2 in update panel so i want to insert item in ddl using following condition. It is working fine but when you choose ddl2 more than one then it insert item every time meand duplicate value and populate ddl1 every time.

{
if (DropDownList2.SelectedValue=="1" )
{
DropDownList1.Items.Insert(0, new ListItem("first", "1"));
DropDownList1.Items.Insert(1, new ListItem("Second", "2"));
DropDownList1.Items.Insert(2, new ListItem("Third", "3"));
}
else if (DropDownList2.SelectedValue == "2" )
{
DropDownList1.Items.Insert(0, new ListItem("first", "1"));
DropDownList1.Items.Insert(1, new ListItem("Second", "2"));
}

I need to check for duplicate records before inserting them into the SQL database.Thus I have the following codes:
For count = 0 To GridView1.Rows.Count
If (GridView1.Rows(count).DataItem("Student Name").Equals(dtDataTable.Rows(count).Item("Student ID"))) Then
lblMsg.Text = "Records Existed"
End If
but there are error message. "Object variable or With block variable not set."
This code cause double record... i checked my insert code for all tables and it works fine...
and this is insert code:
StoreDO store = new StoreDO();
List<BrandDO> brandList = new BrandBL().SelectBrands();
StoreBL storeBL = new StoreBL();
store.StoreName = txtStoreName.Text;

Range validator ..
I have a text box , i need to check restrict user to enter minimum 5 character and maximum 50 character using range validator.
We are writing a feature that allows an administrator to block/allow ranges of ip addresses.
Is this easy enough to do with c#?
I was thinking of looking at each number [here].[here].[here].[here] and then mathing it with the ranges and just seeing if each number was between the two?
Will that work for standard ip v4 addresses?
