Public Structure In Web Service As Return Value In Function
Sep 24, 2010
I have a windows app that references a web service I created. In the web service, I created a function that needed to return more than one value. Because of this, I created a public structure in the web service:
Public Structure MyRecordSet
Public lstOfDataInRecord As List(Of String)
Public iNumberOfRecords As Integer
End Structure
Here's the function - the return value is MyNewRecordSet:
Dim MyNewRecordSet As MyRecordSet <WebMethod()> _
Public Function GetDataReturnList(ByVal sql As String, ByVal sTableName As String) As MyRecordSet
MyNewRecordSet.lstOfDataInRecord = New List(Of String)
[Code] .....
Anyway, I see it's a conversion issue, but not sure how to resolve it. This is my first attempt to use a public structure in a web service and receive a return on it from my app.

In what situtations is it best to use reference arguments to return values?
Sub Example(byref value as integer)
value = 3
End Sub
In what situations is it best to return the value (perhaps in a structure for more complex types)?
Function Example() as integer
return 3
End Function

So I've run into a case where I have a class that can store either a string or a numeric value, and I want a single property to return one or the other (it would be a failure for both to be set). I'm using a custom generic class to deal with the numerics (so I can use signed, unsigned, and nullables), and will be storing the string in a separate variable.
In theory, if overloading could be done based on the return type, I could do this quite easily. But .NET currently disallows this. So I am wondering if there is some other really-far-out-there trick (outside of MSIL generation via Reflection.Emit) that could accomplish the same thing.
I'm open to ideas via delegates, pointer dereferencing, generics, mystical rites, etc. Also interested in any thoughts or pros/cons of such possibilities as a learning tool. If using a standard Object is the only way to achieve what I want, then that's fine with me. But It's difficult to find the correct set of keywords to hunt down this kind of capability on Google, so I thought I'd ask here before I moved on to doing something else on the project.

EDIT: The above class is just an example of what could be returned from a web service. I won't have access to modify it at all, sorry if I didn't make that clear.Is it possible to somehow make a clone this class, so that it retains all of the properties values, but hides the fact that there is a Public function?I'd like to be able to take some existing classes we retrieve from a web service(which we didn't write) and be able to pass them on for use in an application, but without exposing the functions. I don't want to go down the route of creating my own classes that specifically define each property and write the values in (due to the sheer size of some of them), so I'm looking to see if there is anything dynamic I can utilise (maybe there is a way using reflection?).

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 am trying to create a Public Sub / Function that will allow me to pass certain variables into it and this will affect the output. e.g.
DIV ID = InfoDiv
CSS Class = "Warning"
LBInfoMsg.Text = "An Error has occured"
DIV Visibility = True or False
I would like to type something similar in the code behind page:
InfoMsg(InfoDiv, "warning", "An Error has Occurred", True)
Public Sub InfMsg(ByRef MyDIV As System.Web.UI.HtmlControls.HtmlGenericControl, ByRef CSS As System.Web.UI.WebControls.Style, ByVal strMessage As String)
strMessage = strMessage.Replace("'", "''")
MyDIV.Attributes.Add("Style", "warning")
MyDIV.Visible = "True"
End Sub

Class A gets, as part of it's constructor, a pointer to class B and saves that pointer in a private variable. Class B exposes a public function, F. I'd like for class A and all classes that inherit from class A to NOT be able to call B.F.The idea is that class A will implement its own version of F, one that calls B.F, but the rest of the code should not be calling B.F. If it matters, the two have different function signatures.Maybe another way, like a class C that inherits from class B and hides the public functions? (Cant that even be done?)

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?
