I am trying to debug my code, which involves a simple webservice that passes parameters to a data class, which calls a stored proc, and returns one row of record. I am not getting any error messages, but I am not getting any records back either.[code]
View 1 RepliesI have a view on some data in my database it returns the data as I would expect, for example
Call Date To From Phone Number
20/1/2010 00:00 23:59 08923233223
20/1/2010 00:00 23:59 08923233245
However when I have added this to my Entity Model and query it I get duplicate(and unexpected) data appearing
Call Date To From Phone Number
20/1/2010 00:00 23:59 08923233223
20/1/2010 00:00 23:59 08923233223
I am simply binding a Entity Data Source to this Entity but I am left scratching my head as to why the data is being returned differently
EDIT: Interestingly this can't be the result of some strange under the hood join as the row counts match as expected. I have also put together a query myself to test with the same odd results.From o In App.Entities.v_PersonalRules Where o.companyid = CompanyID Select o. I am using Visual Studio 2010, .NET 4
EDIT: The front end code is fairly simple
<asp:EntityDataSource ID="EDS_Personal" runat="server" ConnectionString="name=Entities_NEW"
DefaultContainerName="Entities_NEW" EnableDelete="True" EnableInsert="False"
EnableUpdate="True" EntitySetName="v_PersonalRules" EntityTypeFilter="v_PersonalRules" >[code]....
I am having some issues in attempting to display a recordset from my webservice. Currently my application involves a client feeding their values into my webservice.The webservice will then call a vb.net database class, which executes a SQL stored procedure, returns a recordset to the database class, and the class will pass the recordset back to the webservice, which will display it to the client in xml.
The problem I am having passing the recordset from the database class back to the webservice in a format that can be sent back to the client. I can't seem to convert the recordset to string format. Would it be better to have the record returned in XML format?
I am messed up with the below query[code]...
but when i run the query in my project the reader in not reading correctly...even if values are present is returns false and if values are not there then it returns true.
I'm trying to query a remote machine and get the cpu percentage similar to task manager.. I have the following code:
Code:

I have the follow Linq query that is in a web application that was converted from .NET 1.1 to 3.5:
dim objListOfFilteredDataRows = from datarows as datarow in objDataSet.tables(0).rows _
where datarows("SomeColumn") = SomeValue
I have the exact same query in an application that was created using .NET 3.5 and the query returns an IEnumerable. However the query in the converted application is returning:
{Name = "WhereEnumerableIterator`1" FullName = "System.Linq.Enumerable+WhereEnumerableIterator`1[[System.Data.DataRow, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]"}
**Edit: When I highlight the expression, the intellisense says that it doesn't know the type of objListOfFilteredDataRows and assumes its a type of "Object". Why is the type not infered in the converted 1.1 application but is infered in the "native" 3.5?**
What am I missing here? How do I convert the "WhereEnumeratorIterator`1 to an IEnumerable?
I have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:
Gender.Current Occupancy < Max Occupancy Available Flag is Checked I know this should return results but it keeps returning an empty set.Code is below
[code]...
UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.
Just a quick question about LINQ, I want to use a value from the returned dataset to lookup a value and return this. The line I am struggling with is .ViewingNotes = NewViewing(pt.ProspectId).GetViewings().Columns(7).ToString(). Is this possible?
With BusinessLayerObjectManager.Context
Return (From p As [Property] In .PropertySet
Join pt As Prospect In .Prospects On pt.Property.propertyID Equals p.propertyID

I'm doing some XLINQ in VB for work. I basically need to pull some values from a small chunk of XML as listed here:

<cmbQtyCheck>Reject</cmbQtyCheck>

... Leaving out the implementation of the For Each loop....So I have stuck a break point on the for each and the collection has no elements in it.

I am developing an application that based on when a user has last entered a payroll, my program tells them the next available Sunday that is available to them based on
1. The date that the last time payroll was entered
2. If payroll ran = "yes" or "no"
I have a sql query that returns the next Sunday back to me based on this criteria, but when I put it into my application, it returns 1/1/0001 to me.
Here is the query:
select MAX(payrolldate) AS [payrolldate],
dateadd(dd, ((datediff(dd, '17530107', MAX(payrolldate))/7)*7)+7, '17530107') AS [Sunday]
from payroll

I am building an application where a button click runs a sql query and shows a user the next available date that they can process from. The problem was that it needed to be the following Sunday and not the following day.

Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Im currently working on an n-layer application that does alot of database work.90% of all database queries are updates, and inserts and I want to be able to view the results of my query in the presentation layer.I was thinking of creating a QueryResult class that has a few properties like QuerySuccessful (boolean), Message (string) - holds success or error message, and optional field to hold any additional data that may need to be passed back to the presentation layer.So I guess my question is, am I going about this the correct way by creating a QueryResult class, and passing that back up through the layers to my PL?

How can i write a linqToXML query so that it returns me an IEnumerable containing each child element, in this case all five child elements of , so that i could iterate over them. The order of child elements is not definite, neither is number of times the may appear.
In my code I enter a string in a text box and have the query check the server for the entry. If it exists it returns the string and the date into two separate variables. The database only has TrackingNumber and Date. Below is the code. As of right now i get "Invalid attempt to read when no data is present." at the "If (sdr("TrackingNumber") IsNot Nothing) Then" line.

I am using VB2005 ASP/VB. I have a Gridview placed on a web form which is popluated by a query based on user input.select * from view_main where initials = ddlfilter.textThis works fine.

the total number of records for the previous day where the feed is, 1, 3 and 5 i.e.the feeds I need to retrieve totals for will just be selected based on what I need for instance it could be box4 and box 5...not specifically odd and even...I hope this makes it more clearer..what I have for all records:
select sum(count) as [total] from PostTable where Cast(dateinserted as DATE) =
CAST(getdate()-1 as DATE)
I typed this question once already, hit preview, and somehow never got the preview and lost what I typed. It has been that kind of a day.So here is my quick overview then I am going shopping. I am using OLE DB to select from an excel spreadsheet. It has over 15000 rows and 33 columns. Sometimes even when a cell is not null, it is returning a null value. If I just do a "select * where [termination date] is not null", for example, it will return no rows even though I can see with my own eyes that sometimes termination date is not null.
