Strongly Typed FaultExceptions Not Working

May 10, 2012

I'm trying to pass strongly typed FaultExceptions from a WCF service to a Silverlight client but all I'm getting is the generic "The remote server returned an error: NotFound." response, while using the same code to throw generic FaultExceptions works fine. So, if I doThrow New FaultException() I get it back in the e.Error parameter of the Silverlight callback, while a Throw New FaultException(Of clsServiceFault)(clsServiceFaultInstance) results in the not found error.

clsServiceFault has already been declared as a data contract like so:
<DataContract()> _
Public Enum ServiceFaultTypes
LoginFailed
SessionExpired
End Enum
[Code] .....

The WCF method in which the fault is thrown has been decorated with the FaultContract attribute and I'm also changing the HTTP response status code to 200.
<OperationContract()> _
<FaultContract(GetType(clsServiceFault))> _
Public Function GetCustomersData(...)
...
System.ServiceModel.Web.WebOperationContext.Current.OutgoingResponse.StatusCode = Net.HttpStatusCode.OK
Throw New FaultException() 'Works
Throw New FaultException(Of clsServiceFault)(new clsServiceFault(..)) 'Does not work
...
End Function

Why Are Interfaces Not Strongly Typed

Jan 8, 2010

I have the following code compiles without issue. Of course, I get an invalid cast xception when executing the Dim C As IDoThingsC = GetThing_C(). Am I missing something?Would you ever want to return an object that does not meet the interface requirement for a function return value?

Public Class ClassA
Public Sub DoThings_A()
Debug.Print("Doing A things...")

ASP.NET MVC Strongly Typed View Convert From C# To .NET?

Nov 28, 2009

I'm starting to learn ASP.NET MVC and since I work in a VB.NET shop I'm converting an example from C#. I'm trying to implement a strongly typed view and the example I'm looking at shows the following:

<tr>
<td>Name:</td>
<td><%=Html.TextBox(x => x.Name)%></td>
</tr>

I've come up with the following in VB.NET:

<tr>
<td>Name:</td>
<td><%=Html.TextBox((Function(x As Contact) x.Name).ToString)%></td>
</tr>

Is this conversion correct? This seems really cumbersome (I know, I know, VB.NET is more cumbersome than C#, but I have no choice in the matter).

C# - Dynamically Get A Particular Method's Name In A Strongly Typed Way?

Apr 7, 2009

I'm looking for a the shortest/aseist way in VB.NET (or C# but using VB.NET at the moment) to get the string value of a method's name dynamically given the method call.For instance, I have a class like this:

Public Class Blah
Public Sub Foo()
End Sub
End Class

Now Foo is a strongly-typed cover for a dynamic setting and I have an event handler that will fire when the setting changes and return the string name of the setting that changed.

I'd like to be able to switch/select on this string and have a case based on the Foo() method. To do this I need to able to get the string name of the Foo method from the method call itself (i.e. somehow GetMethodName(blahInstance.Foo())).

Creating A Strongly Typed DataTable?

Jul 18, 2010

I'm wanting to have some datatables that are just used temporarily, mainly for creating and listing friendly versions of data that will be easier for the user to read in drop-down combos etc.

I would like them to be strongly typed to pick-up bugs at design-time. However I'm struggling to know how to achieve this. Do I need to create a custom class and inherit from DataTable and build the columns in the class constructor?I don't need a Dataset, just a DataTable?

DB/Reporting :: Strongly Typed Dataset

Apr 20, 2009

Firstly here's the code and i will explain my problem underneath. [code...]

Now as you can see I have a variable that holds a value member of the combo box Products which is the productID of the current product selected. Then it searchers through the products datatable and once its found the correct product or not it stores the answer in slectedproductrow. next I test to see if selected product row has found the product if it has i then see if the product has already been added to the order by seraching the the customer current order datatable if it hasn't it adds the current information to the order by using selected product row.

Now the problem i get is when i add the same product it still adds the information again as currentorderrow comes back as nothing everytime even if the product has been added before but if it was in the table which it should be it should skip that bit and just go to add the current qtys toghther.Also if i go to add a diffrent product it overwrites the the other one. So i can't store the customer order. Its like i can't store more than one row. By the way I have a datagrid and can see the product get over wrriten.

Asp.net - Strongly Typed Stored Procedure Resolution In .NET?

Mar 26, 2009

Currently we generate classes in App_Code by returning all the sprocs from all of our databases and adding the correct parameter types and names to a SqlCommand object and then returning it in one giant class. This means we can do things like MyCmd.cmd.Parameters("MyParam").Value = "whatever" when we want to pass parameters to a SqlCommand for a stored procedure without having to add the parameters with their relative data types every single time we make a call. It also means that we have to look up the exposed parameters for each sproc because they are merely strings.

To put it into perspective, for every parameter you want to deal with in a sproc you'd have to do this:

cmd.Parameters.Add(New System.Data.SqlClient.SqlParameter("@Param", 3, 10, 1, False, CType(0, Byte), CType(0, Byte), "", System.Data.DataRowVersion.Current, Nothing))

Really this is undesirable as it'd mean an Intranet/Internet application would explode into gazillions of lines of code to achieve really quite simple tasks.We're looking into refactoring this in such a way where we can do something like MyDatabase.MySproc.MyParam("value") instead by making it strongly typed. Unfortunately this means our App_Code folder will be twice the size it already is because such a large quantity of code would be required.

I've written a short example of what I mean:

Public Class MyProc
Dim cmd As SqlCommand
Public Sub New()

[code]....

Are there alternatives to having to do this that we are unaware of? I'm sure this is a common problem amongst many businesses developing inter/intranet applications.

Cannot Reference A Dataset Table Using The Strongly Typed Name?

Apr 7, 2012

I cannot figure out for the life of me why I cannot reference a dataset table using the strongly typed name. I created a "news" table in a dataset to write out and read in a simple xml.

If you look at the code below this does not work: 'Dim TableFail As ADataSet.NewsDataTable = ds.NewsDataTable 'Does not work

I can access the table by using an untyped name however: Dim NewsTable As ADataSet.NewsDataTable = ds.Tables("News") What is the proper way of accessing the datasets 'typed' datatables name.

Create A Strongly Typed View Page Using ASP.NET MVC ?

Apr 28, 2009

I am using the ASP.NET MVC VB.NET XML Literals View Engine created by Dmitry Robsman and described on his blog in this post.

[URL]

I would like to create strongly typed view pages using this view engine, but it doesn't seem to contain the requisite VbView(Of TModel) generic type by which I would create such a view class.

The end result should look something like this:

Namespace Views.Client
Public Class Details(Of Models.Client)
Inherits SiteMaster

[Code]....

Once there is a VbView(Of TModel) class that inherits from Dmitry's VbView class, how to hook that up so that it works with standard MVC controllers that call the view like this.

Function Details(ByVal id As Integer) As ActionResult
Dim c = SomeGetClientFunction(id)
Return View(c)
End Function

Programming Languages - .net Delegates Strongly Typed?

Dec 14, 2011

I'm learning delegates in VB.NET and am confused about delegate types. In reading about delegates, I learned that delegates are a data type that can refer to a method with a particular kind of signature. So in the same way that a String can refer to characters, a delegate can refer to a method (for instance) that takes an integer as input and returns an integer as output. But in playing around with delegates, I found that this was not the case. The code below compiles and runs--even though I don't obey the 'typing' in my delegate signature. I'm confused. Am I missing something?

Public Delegate Function myDelegate(ByVal i As Integer) As Integer' int in, rtrn int Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim md As myDelegate 'should be of type int in, rtrn int md = New myDelegate(AddressOf squared) 'allows assign to string in, string out

Asp.net - Provide Strongly Typed Access To The Session Object

Nov 6, 2009

What is the best way to provide strongly typed access to the session object? I am planning on turning on Option Strict, which is causing the compiler to complain about my lazy programming technique of directly accessing the session object:

Dim blah As Integer = Session("Blah")

My initial thought is to create a class that wraps the session and provides strongly typed properties for the information stored in the session. However, I cannot decide if the class should be a singleton, or instantiated on every use, or where the code should reside (i.e. within the web project or within a class library).

I'm leaning towards a singleton in my class library, but I don't know if that is the best solution, or if I am missing any other possibilities.

Proposed Solution:

Public Class SessionAccess
Public Shared Property Blah(ByVal session As HttpSessionState) As Integer

How To Bind Custom Class With No Strongly Typed Properties

Mar 10, 2009

I need a simple class with only one Public property and no Public methods (the final Class will be more complex, but for testing this is all I need). The Property is "Item" and takes a "String" as a parameter. It returns a "String" based on the parameter. I then want be able to add instances of this object to a List or Array, and then Bind it to a Repeater or a ListView......most importantly, I want to be able to then refer to values in my simple Class via the Eval function:
<%# Eval("SomeIDString**") %>**.

I can't Bind at all unless I declare the Item property as the Default property...why?
When I use "Eval", I get an error in the lines of "[some property] does not exists". indeed it doesn't, because everything is accessed via the Item property. it then does works if I replace "Eval" with "Container.DataItem". Is there a way to use Eval instead of Container.DataItem? I would rather not have my class inherit any other classes because I want to keep it clean from supurfulous properties and/or methods.

Are there interfaces I need to implement? Also, the reason I want to use Eval, is that as much as possible, I want to make the use of this Class simple, so the coder doesn't need to worry about special cases. I just want it to work, much like the DataTable Class, but with a much simpler, lighter-weight implementation.

Programmatically Fill All Tables In A Strongly-typed Dataset?

Apr 29, 2010

I have a SQL Server database for which I have created a strongly-typed DataSet (using the DataSet Designer in Visual Studio 2008), so all the adapters and select commands and whatnot were created for me by the wizard.

It's a small database with largely static data, so I would like to pull the contents of this DB in its entirety into my application at startup, and then grab individual pieces of data as needed using LINQ. Rather than hard-code each adapter Fill call, I would like to see if there is a way to automate this (possibly via Reflection). [code]...

Strongly Typed DataSet Connection String At Runtime?

I'm sorry but Microsoft did not think about this very well. I have used the dataset wizard to connect to my sql server and the connection string was placed in the app.config file.

So I need a way for each one of my users to specify their connection either during installation or after installation. I would appreciate any help in this matter.
