.net - Member With Identity 'ReturnValue' Does Not Exist In The Metadata Collection" Error?
Nov 28, 2010
Im setting up an OData provider in visual studio. The error that im receiving really doesnt have anything to do with OData side of things.I have a table type in my ado entity data model and whenever I try to insert a record into this table i get the following error: {"The member with identity 'ReturnValue' does not exist in the metadata collection.Parameter name: identity"}

I have an existing project with a silverlight3 app. First I created SALESservice.svc.This is working fine. Now I added another TARGETservice.svc to my project and rebuilded my entire project but when I am trying to add the service reference in to the silverlight app I get the following error:
There was an error downloading metadata from the address.verify that you have entered a valid address. I didn't write any code in ISALESservice.svc AND ITARGETservice.svc . I have written in SALESservice.svc.cs AND TARGETservice.svc.cs files.Is this causing error? But for SALESservice.svc it is working. I didn't add any code in web.config file.

I have just deployed my ASP.NET MVC 2 application using EF 4 and I am getting the following error:
Unable to load the specified metadata resource.
On my local machine it runs fine with no errors. This error only comes now when I deployed to the server. I have my enity data model file in MyProject.EntityModel. I used the POCO entity generator to separate my context and entities. These 2 are in another project called MyProject.Entities. I have the connection strings in the app.config in the 2 projects exactly the same. The connection string in the web.config in my MVC app is also the same. I'm not sure why this is giving me issues? I'm also running the app in IIS (that comes with Windows 7) and it works fine. The IIS version on the server is 6 (I think). Here is the full error message:
InnerException

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?

I have just finished converted a vb.net app to c# and one of the lines is to get @ReturnValue from the parameter.I ended up having to CAST a lot of things..Is there not a easier wayhere is what i have
int rc = ((System.Data.SqlTypes.SqlInt32)(((System.Data.SqlClient.SqlParameter)(cmd.Parameters["@ReturnValue"])).SqlValue)).Value;
In vb.net it was as simple as doing this
Dim rc As Integer = Convert.ToInt32(cmd.Parameters("@ReturnValue").Value)
Alot easier :-)But the problem with C# is the property Value isn't available unless I Cast to SqlParameter and i also need to cast to Sqltypes.SqlInt32 - i can't just do a standard Convert.ToInt32

I have two member roles at my project:
1.) Administrator
2.) Member
From the toolbox in Visual Studio 2008, I have dragged and dropped the create user wizard into the stage. I aim that a guest can register itself and automatically join the "member" role. Not the role "administrator". How can I do that?

I just got a new desktop computer with Windows 7 Pro as the operating system. I installed Visual Studio 2008 on to this new computer and tried to open a previously existing ASP.NET 3.5 solution that displayed perfectly fine on my previous computer (this previous computer used the Windows XP operating system, IIS6, and IE7 browser). However, in Windows7/IE8, I'm receiving the following error:
Server Error in '/' Application.
Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: The file '/MasterPages/MainMaster.master' does not exist.
Source Error: Line 1: <%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="default.aspx.cs"[code]....
when I tell you that the file '/MasterPages/MainMaster.master' file does, in fact, exist. In addition, this file's location is properly referenced in the code (as indicated in Line 1 above), and as I said, was displayed properly by the browser in my previous computer. It might also be helpful to note that I've tried to navigate to other pages in this site, and this browser displays the same message for any and all master pages located in my MasterPages folder. In summary, for some reason the browser cannot see any pages in the MasterPages folder. Can anybody tell me why I'm getting this error message when the folder and file is exactly where default.aspx says it is?

I have following model class:
public class WebModel
{
public List<ArticleModel> Articles { get; set; }
}
public class ArticleModel
{
public int ID { get; set; }
public double ValueParam { get; set; }
}
Then I have the controller with the two actions:
[Authorize]
public ActionResult Index()
{
WebModel model = new WebModel();
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
[Authorize]
[HttpPost]
[ValidateInput(false)]
public ActionResult Index(WebModel model, string saveButton)
{
ModelValidation.ValidateWebModel(model, ModelState);
if (ModelState.IsValid)
{
return RedirectToAction("Create", "Article");
}
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
And this is my view:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Web.Models.WebModel>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<%var controller = Session["controller"] as Web.Code.SessionController; %>
<%Html.BeginForm(); %>
<div>
<table width="100%">
<%foreach (var article in Model.Articles)
{%>
<tr style="text-align: right">
<td>
<%:Html.DropDownListFor(m=>m.Articles.FirstOrDefault(f=>f.ID == article.ID).ID, new SelectList(controller.CurrentProdukt.Articles.AsEnumerable(), "ID", "Name", article.ID)) %>
</td>
<td>
<%:Html.TextBoxFor(m => m.Articles.FirstOrDefault(f => f.ID == article.ID).ValueParam)%>
</td>
</tr>
<%} %>
</table>
</div>
<table style="width: 100%">
<tr>
<td>
<input type="submit" name="saveButton" value="Save" />
</td>
</tr>
</table>
<%Html.EndForm(); %>
</asp:Content>
If I press the submit button, I get to the second action method in the controller (the one with the HttpPost attribute). In this action, the object model itself is not null, but the "Articles" list inside is null.

I have a website I developed in VS 2008 targeting .net 3.5. It has worked well. I recently upgraded to VS 2010 and needed to make a few changes to the site. However, I'm receiving compile errors (haven't made any changes to the code yet--was just launching the site to make sure it worked ok). I get "Contains" is not a member of system.array. Everything I've read states that the contains method was added in .net 3.5, which I know to be correct because it was working in VS 2008. I've been targeting .net 3.5 in VS 2010, but it still isn't working. I also used linq quite a bit with linqkit to do dynamic queries and all of my linq queries were saying my queries weren't queryable (I don't have the actual error in front of me). Anyway, to fix that one, I had to import system.linq (I previously had system.data.linq and it was working fine). To reiterate, I haven't targeted my site to .net 4 in VS 2010, I've left it targeting .net 3.5.
I tried converting my arrays to arraylists since arraylists were still pulling up with a .contains method, but then it broke my linqkit queries when I ran it on the site.
Here is my linqkit query:
Dim str() As String = archlist.ToArray(GetType(String))
Dim str3 As New ArrayList
str3 = ArrayList.Adapter(str)
predicate = predicate.And(Function(l As CompatTesting) str3.Contains(l.application.cpuarchitecture))
Before, I didn't have the arraylist conversion, I just had str.contains and it worked great to generate a sql "in" statement. Now after using the code above, the site launches, but when I actually run the code, I get Method 'Boolean Contains(System.Object)' has no supported translation to SQL. I also tried upgrading my linqkit dll to the latest version but it didn't help.
My questions are, since I'm targeting the same .net 3.5 framework in 2010, why is it not allowing me to use array.contains anymore? Maybe if I can address that issue, it will fix my linqkit issue where it says "contains" has no supported translation to sql.

Since both retruns the value. Then whats is the difference between ParameterDirection.ReturnValue and ExecuteScalar()
int i = Convert.ToInt32(cmd.ExecuteScalar())
objCmd.Parameters.Add("@ColumnnTest", SqlDbType.Decimal).Value = objPropertiesClassName.Columnnumeric;
objCmd.Parameters["@Columnnumeric"].Direction = ParameterDirection.ReturnValue;
objCmd.ExecuteNonQuery();
int i = (int)objCmd.Parameters["@Columnnumeric"].Value;

How and where can I get the returnvalue from my "DeleteGuestById" method to show the right error message to my user?
I have this:
Protected Sub gvGuestlist_OnRowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles gvGuestlist.RowCommand
If e.CommandName = "DeleteGuest" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim data As DataKey = gvGuestlist.DataKeys(index)
Dim GuestId As Integer = data.Values("id")
odsGuestlist.DeleteParameters.Clear()
odsGuestlist.DeleteParameters.Add("id", GuestId)
odsGuestlist.Delete()
End If
End Sub
In my BLL:
<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Update, False)> Public Function DeleteGuestById(ByVal ID As Integer) As Integer
Dim returnval As Integer
GuestlistAdapter.DeleteGuestById(ID, returnval)
Return returnval
End Function
I think I have to be in the ObjectDatasources' "OnDeleted" method but I have no what code to place there.

I am using the Ajax AutoCompleteExtender control, and employing a public shared function to act as a web service without actually creating a web service. This approach works perfectly, however I would like to take this one step further and filter my query from a drop down list, however I am unable to accomplish this. Whenever I attempt to reference the drop down list from within the public funtion, I get:
"cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class."
I have found very limited documentation on resolving this error. Pretty much every solution includes removing the shared reference instead of handling it.
When I remove the Shared reference and just make it private, the AutoCompleteExtender ceases to function completely (i.e. functions a a regular textbox). Here is my code:
If you notice that I am not referencing the @YRQ parameter in my query, that is intentional. I will replace the subquery with that parameter when I am able to get this working.
