Return An (Anonymous Type With A Function) From A Function?

Mar 3, 2011

Just so it's known, this question is mostly academic, even though I tried to use the concept in a real-world solution. I realize the example is contrived, but I believe the concept is valid.I want to write some fluent code like this:

[code]...

I realize that I can't force an anonymous type into a specific type (like implementing an interface or some other class), and I don't want the overhead of defining a specific class just to match my desired fluent name with the actual method name. So I was able to make the code work like this:

copy(my_first_file).to.Invoke(my_second_file)So there is no IntelliSense or type awareness there, and I have to include the Invoke in order to have the method run. How can I get more type safety and exclude the Invoke method, under these constraints: Anonymous Type returned from Method No additional classes or interfaces Preferably, I do not want to pass in another parameter to the copy() method that tells what type to return, unless copy becomes a generic method (but I think that means defining another class/interface, which I don't want to do)

I want to include an optional parameter in a function statement that is of the type Unit. For example:

.net - Default Value Of Nullable Integer Different In If() Function

Dec 7, 2010

I am trying to understand why the two code samples behave differently. I always believed the If() function to mimic the If language feature. Or am I looking at a behavior of Nullable(Of Integer) that is causing this?

Sample #1:
If Not String.IsNullOrWhiteSpace(PC.SelectedValue) Then
Dim pcFilter1 As Integer? = CInt(PC.SelectedValue)

Public Function On Default Page Or Somewhere Else?

Aug 30, 2009

I have a public function declared in my code-beside on default.aspx.vb. I needed to add a second page to my project and copied and pasted that function into the second page, but when I test the page I get an error saying there's a conflict with the same public function on the default page.

If I remove the function from the second page, i don't get the error, but will it still be accessible if called on that page, even though it's on the default page? Or do I need to place it somewhere else so that it's accessible to both pages?

Function Return A Value Byref Instead Of The Default Byval?

Jan 18, 2012

Can a function return a value byref instead of the default byval? That is to say, allow me to directly edit the variable that it is retrieving instead of just giving me a copy of that variable.Right now I'm trying to write a function that will return, based on what the user has selected through a combobox, a particular setting (eg. My.Settings.somethingHere). I then want to be able to edit the setting directly through just calling the function. Is that at all possible?

Error - XML Deserialize : No Default Member Found For Type

Mar 19, 2010

I have XML files I am trying to read and import. I have XSD files and have used the XSD.exe tool to create classes for the elements found in the XML files. The problem I have having is that the same file structure can be used for different "message types" (different data structures for different purposes). Because of this, the structure of the file is roughly this:

<Envelope>
<BatchID>SomeNum</BatchID>
<Messages>

[code]....

Where the Order element is, it could be one of a few different element types in the message based on the message type. Currently, I'm trying to read an order file.The XSD tool created all the classes fine but it creates an 'Item' object for that inner element and makes it one of the other strong types during the deserialization, so I end up with something like:

Envelope.Messages(0).Item

Item is just an object and is not strongly typed until the deserialization happens. If I look at the data in Item in a watch window during debugging, it shows it is the strongly typed class and has all the data in the members I would expect to see, but I can't seem to access them by name or set an instance of the strongly typed Order class equal to the Item object. Any attempts I've made so far to read the data have resulted in the "No default member found for type 'Order'" error.

Function Without Return Type?

Dec 23, 2010

In my project (which I inherited from someone) there are a lot of functions like:

Public Function DoSomething(ByVal s As String)
' Do something to public properties
End Function

And they are called like this:

DoSomething(s)

So the return value is ignored (which is object, as I see in the docs). Is it safe to change all these functions to Subs? Could I break something which isn't so obvious?

.net - Child Type In General Function?

Apr 15, 2010

I have a MustInherit Parent class with two Child classes which Inherit from the Parent.How can I use (or Cast) Me in a Parent function as the the child type of that instance?EDIT: My actual goal is to be able to serialize (BinaryFormatter.Serialize(Stream, Object)) either of my child classes. However, "repeating the code" in each child "seems" wrong.

EDIT2: This is my Serialize function. Where should I implement this function? Copying and pasting to each child doesn't seem right, but casting the parent to a child doesn't seem right either.

Detect Variable *name* (not Type) Within A Function?

Jun 12, 2009

So, let's say I have this code (VB.Net)[code]...

What I don't like is:

- relies upon reflection

- loosely typed (no compile time checking)

- I'd rather store the binding information somewhere other than ID, but don't know where else it could go within the aspx definition. Moving the binding declaration to the code behind would be better in some ways, but worse in others.

Differentiate Return Type Of A Function?

Mar 27, 2012

I know a little about using a user specified type IE IIf(Of ReturnType)(ByVal expression as Boolean, ByVal TruePart As ReturnType, ByVal FalsePart As ReturnType) As ReturnType...Which works, however I've been trying to get this to work, but can't..

Protected Function InverseSign(Of ReturnType)(ByVal value As Double) As ReturnType
Dim result As String
Select Case Math.Sign(value)
Case -1: result = "+" & Math.Abs(value).ToString()

[code]....

Using try cast just gives me the error saying ReturnType has no class-constraints? whatever that means..But my goal here is to be able to return either a string or double.. However every method I've tried to convert my result string to the ReturnType doesn't work.I've also tried simply overloading the function, but I can't because they only differ by return type. So that didn't work either.
