ADO.NET :: Invalid Attempt To Call MetaData When Reader Is Closed?
Mar 25, 2011
I am creating a C# web application where I am attempting to extract data from my SQL Server and return the data in a single data stream into the properties of my object instance. Here is the code from my Presentation Layer where I am calling the Load method of my BLL:
[Code]....
Here is the code for the method in my BLL:
[Code]....
Here is the fillObject method from the BLL as well:
[Code]....
Here is the code from my DAL:
[Code]....
In the end I get an "Object reference not set to an instance of an object" error on the next line of code in my Presentation Layer. However, when I step through the code I notice the myDataReader in the BLL does not get populated and the step through actually errors out during the fillObject method at the line "myObject.string1 =" with the error stated in the title. I am not sure why the myDataReader in the BLL is closed and why I this does not work. At my work we have this same code logic only in VB.Net and it works perfectly. have any insight as to why this does not work in C# and how can I correct this?

I have a function which allows me to quickly load SQL results into an SQLDataReader.
This is a very effective way for me to do this as it can be used for inserts, updates and selects very easily throughout my code.
However, I have noticed some potential memory issues with my site while using this (I keep having to do iisresets when working locally because all the pools are used up) so I am trying to use "Using" rather than "Dim" in an effort to ensure that the connection is always disposed.
I call the function in the following way:
Dim RS As SqlDataReader = SQL.Exec("sp_MyStoredProcedure " & ID)
If RS.Read Then
Return RS("Column_Name")
End If
RS.Close()
[Code].....
I now get the error "Invalid attempt to call Read when reader is closed" when calling the function on the line "If RS.Read Then".

Environment is : vwd2008, asp.net 3.5, linq to sql object model, formview, stored procedure used for query.On going problem... I have a simplified page with a webform content area from a master page. The content area contains a FormView connected to an object data source thru the design view tag. The O/R designer has the Lease Table and the stored procedure in the method area.
The stored procedure selects all records from a single table. I an using the DatabaseDataContext and selecting stored procedure name which has "return SingleResult".. There is no code written; the design view was used to create everything. The stored procedure executes in VWD 2008 express tab and shows desired records. I would like to use the O/R and Linq to SQL, and objectdatasource BUT.

I've read up on this error from other posts and on other sites, but haven't found a solid resolution to the issue yet. My setup is as follows:
I have a RepositoryBase class that fields certain db calls that all repositories need to perform. In one such call, "GetSecurityGroup", it works most of the time, but will seemingly at random throw an exception with the error "Invalid attempt to call Read when reader is closed." All other Repository classes inherit from this one, and they all use the same DataContext object, which I understand isn't thread safe. Since there could be multiple calls to the DataContext object on the same page, perhaps one is using the DataContext when the next tries to do so. I'm not sure. What can I do to ensure this doesn't happen?

I have several methods where I return a SqlDataReader to populate Gridviews, Listview, etc. I get random "Timeout expired" errors regarding connection pooling, so I decided to add using{} to my methods. The lack of using is a carry over from my more beginner days.Below I included the before and after code. The after code always gives me the "Invalid attempt to call FieldCount when reader is closed" error. I have tried various combination of using{}, but ALL result in the same error.What am I doing wrong? Also, from the code below what is the best way to structure this code to ensure no connection leakage?Before:

Ok I have this object.ascx. Everythings works fine in an Add scenario (model is null). However when the model isn't null I have metadata for the property in object.ascx then when I call Html.Editor(prop.PropertyName) I have a default instance of modelmetadata within that template. About the only value that is preserved is propertyname. My AdditionalValues are gone, IsRequired, Watermark etc all have default values. I'm seeing bizarro state driven behaviour like this all over the place when it comes to templates. It is peeving me.
[Code]....
So my question is: Why does having a non-null model cause a completely unexpected (and stupid) behaviour? I find it hard to believe this is intended.

I have some code in my vb.net code behind that queries a database, and if there is data, outputs it from the codebehind to a datalist on my asp.net page. In addition to sending the data to the datalist on the page, I need to take the value from "mbillaty" that is returned from the sql query, and have that value be the selected value for a drop down box also on the page. I can get either the datalist to fill, or the selected value for the dropdown box to be selected depending upon which bit of code I place before the other (ARGH), but I can't get them to both work together on the page. What am I doing wrong?

I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

In a web page, I call a web service (located in the sub folder WebServices) with ajax asp.netHere my aspx code:
[Code]....
My web site uses integrated windows authentication and all works fine.However, my web service doesn't need authentication and in order to not have 2 requests (because of http code 401), I've allowed anonymous access on the WebServices folder. Doing this, I get the folowing error message when I call a web method: "Invalid web service call, missing value for parameter: user"When I look at my body request with Web Development Helper, I can see {"user":"toto"}. So, I don't understand why it's not working.Another weird thing: when I run Fiddler2 instead of Web Development Helper, every thing works fine. I turn off Fiddler2, and it doesn't work any more.
