Function Without Return Type?
Dec 23, 2010In 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?
Return A List Of Type T?
Jun 22, 2010I would like to have a function(of T) that returns a list(of T) that is assignable to a variable of list(of T).For Example:

Differentiate Return Type Of A Function?
Mar 27, 2012I 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.

VS 2008 Which Type Of Array To Return?
Nov 24, 2009I have a program which connects to an FTP server. my program needs to retreive the directory list of the server. I am doing this in the style of an OpenfileDialog control. now I can get all the information and fill the listview control. however the function I use to fill the listview control with the directory listing and file listing, returns a list(of string)
Because of this I can't determine if a file is a file and if a folder is a folder. I myself know which of them are because while getting the directorylists I check for a string value of D which means directory. if it doesn't have a D then it's a file.
How To Use The Vb Equivalent Of ++ For An Index Property In A Linq Query Projecting A New Type
May 3, 2011I'd normally do this in C# but since I've got to get this code in this particular assembly which is a vb.net one, I'm stuck.
Here's my linq query:
Dim i As Integer = 0
Dim oldAndCurrentIntersectionOnNames = From currentApplicant In currentApplicants _
Group Join oldApplicant In oldApplicants _

You'll see the .Index = i+=1
This was my attempt to do what I'd quite happily do in C# (i.e. Index = i++) in VB. Unfortunately the VB compiler doesn't like that. how I'd do this in VB.

Methodinfo.invoke Return Type Checking?
Apr 14, 2009gv1 is a grid !!
gv1.DataSource = minfo.Invoke(Activator.CreateInstance(classtype), inputParameterStore)gv1.DataBind()
What i get from minfo.invoke i am binding to the grid gv1 !!! But unfortunately its not working for all minfo !!!! Few errors are like :
return type is not IListSource ,IEnumerable or IDataSource !!!!
Hence i need to check if :
minfo.Invoke(Activator.CreateInstance(classtype), inputParameterStore)
returns IEnumerable or IData Source or IListSource !how to do that ?Also if return type is none of these i should display the result in a Textfield by Serializing the data and displaying it as an XML?How to do that too?

Loose Typing - Created A Function With No Return Type
Jun 4, 2009I was playing with vb 2008 express and i created a function with no return type. Basically what it does is i specify a table name and a column name and it returns the value within but it doesn't type it until it gets to the calling variables type. So i have on function that i can use across all my tables.
Eg:
dim mydate as date = getvalue("tblSRs", "datelogged")
msgbox (mydate)
dim desc as String = getvalue("tblSRs", "description")
msgbox(desc)
Both return the correct values. were you always able to leave the typecasting till the end and whats the major downfall?
Error The Type For Variable 'Index' Will Not Be Inferred Because It Is Bound To A Field In An Enclosing Scope
Apr 19, 2009I have some code and there are 2 errors which I don't understand I have tried all sorts...
1)The type for variable 'Index' will not be inferred because it is bound to a field in an enclosing scope. Either change the name of 'Index', of use the fully qualified name (for example, 'Me.Index' or 'MyBase.Index').
2)Function 'GetNewPhrase' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used.
I can't get it to work..
