View 3 RepliesI have a Dynamic Data Website that I created after watching the video tutorials on this website (I'm new to programming, but not computers).I have a SQL Table named 'Adult' that has a 'DOB' column. I would like to add an asp:label to the Default.aspx that does a LINQ to SQL query to determine if it's someones birthday today and if so display their name and age.

View 3 RepliesI am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.
I'm building an ASP.NET MVC site that uses LINQ to SQL. In my search method that has some required and some optional parameters, I want to build a LINQ query while testing for the existence of those optional parameters.
Here's what I'm currently thinking:
using(var db = new DBDataContext())
{
IQueryable<Listing> query = null;
//Handle required parameter
query = db.Listings.Where(l => l.Lat >= form.bounds.extent1.latitude && l.Lat <= form.bounds.extent2.latitude);
//Handle optional parameter
if (numStars != null)
query = query.Where(l => l.Stars == (int)numStars);
//Other parameters...
//Execute query (does this happen here?)
var result = query.ToList();
//Process query...
Will this implementation "bundle" the where clauses and then execute the bundled query? If not, how should I implement this feature?
My application includes BUILDING table with columns BUILDING_ID, NAME, TOWN_ID, I run the LINQ query listed below and need to append two letters to buildings.NAME based on TOWN_ID. I assume that I need to place an "if" or "select" statement inside the query but I can not figure out how to do that,

I have 2 Tables , OrderDetails and Requests In my LINQ to SQL dbml file. OrderDetailsID is a foreign key in Requests Table. I want to write the query to get the sum of UnitCost from OrderDetails based on OrderId. And If there is a row in Requests Table for each OrderDetailsID, and the Requests.Last.RequestType="Refund" I want to reduce the total refund amount from the main sum otherwise If there is no row based on OrderDetailsID, add to sum. Here is the way I implement that. I am looking to prevent using "For each".
iRefund = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1.UnitCost).Sum
Dim objOrderDetails = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1)
For Each OrderDetail As ORM.Entities.OrderDetail In objOrderDetails
If Not OrderDetail.Requests Is Nothing Then
IF OrderDetail.Requests.Last.RequestType="Refund" Then
iRefund -= OrderDetail.UnitCost
End If
End If
Next

I have a basic CMS which I'm adding to a site to display some downloads organised into groups. I have two tables, one for the groups and one for the downloads. I'm using a repeated to display the groups with another repeater inside to display the children. This works perfectly.
However some of my download groups may not have any downloads related to them and I'd like to handle this by filter the groups so that only those with a relate download record(s) are shown.
I'm trying to do this with the query which populates the top repeater based on some ideas I read but I must be going wrong with the syntax.
Here is what I'm using to try and only select downloads groups which have downloads linked to them by the download group ID.

I have two webpages. Default.aspx and Default2.aspx
No code written in both pages.
I put an imagebutton without imageurl in Default2.aspx
The control is redirected to Default.aspx when Default2.aspx requests...
How does this happen?
I need to force SSL when going to the final checkout page (for example from default.aspx to checkout.aspx).
I need to pass variables to this check out page and tried to use server.transfer(https://www.mydomain.com/checkout.aspx). I then use previous page .Fincontrol to read text box and label name to this check out page. If I only do the server.transfer("~/checkout.aspx") then my I can read all vakues of my controls from the passing default.aspx page.
But when I force https:// then I cannot read the control values from default.aspx page.
Please give me some tips on how to get control values to the https:// destination page or if you have another tips on how to do it the right way, please let me know.
