Return Multiple Values From A Function?

Mar 30, 2011

Is it possible to make a function that returns both a datatable AND a list(of custom class) at the same?In my GUI layer, the main form (the application is MDI) calls this function and it has to fill the datagrid on one of its child forms and it also has to fill lot of other child forms with various information that is calculated from my custom class properties.Both the datatable and the class properties are created from the same external database and that's why I don't want to have two separate functions.

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)

Function Does Not Return Nothing?

take a look at the following Code:

Private Sub btnDebug_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDebug.Click

The Funtion ZZNull always returns Nothing, so IsNothing(d) in the calling method should evaluate to True.

But it does not !

When you run these lines, then you will see that IsNothing(d) evaluates to False

How To Use A Function's Return Value

Mar 8, 2009

So the program I am writing validates the controls on the page on button_click.

I want to write a function which checks which step the program is at (0-7) then return something depending on whether or not it validated.

My plan was to return the control which was not valid.

Private Function ValidateInputs() As Control
Select Case wizardStep
Case 0

[Code].....

1. could I return the names off all the controls which did not validate?

2. should I be returning a control type or would something like a string be better?

Return NaN From A Function?

Oct 5, 2010

I've created my own version of HexToDec()  to properly handle the negative flag.  I saw other versions online that used "Not(value)" to do the Pos/Neg inversion, but that does not generate the proper value...   No, it's not the most elegant my any means.  But I couldn't find anything online that actually worked.

Long story short, I want to return NaN in the case that the function is passed a string that is not a valid hex string...

How do I do that?  Everything I've tried generates a compiler error...   (assign return value to double.nan, assign return value to non-numeric, etc)

Existing function is below:

Function HexToDec(ByVal hexStr As String, Optional ByVal signed As Boolean = False) As Long
Dim lngFinal As Long

CLR - Function/Operator Without Return Value?

Sep 4, 2009

I've create a new project, and set treat all warnings as errors in the compile tab.All the other warnings seem to be treated as errors, except the one which I'm interested in "Function/Operator without return value".I have a simple function within a class, which does not show an error if I do not add a return statement to that function. I have read in many places that VB.Net returns a "hidden" default value if the returns statement is forgotten.My software went out to production where an overloaded function was missing a return statement, which wasn't highlighted due to the above.

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?

No Warning In .NET When Function Has No Return?

Feb 25, 2010

warnings got me thinking about old issues that always goofed me up when I was writing more VB.NET code.One of them was the fact that the compiler didn't warn if you declared a Function but never did an explicit Return statement or assign to the Function name. Running Visual Studio 2008, I just made a small experimental project, and it seems as though the behavior has never been fixed.I created a Visual Basic Console application, with the following code:

Module MainModule
Sub Main()
Dim test As Boolean = TestWarning()[code].....

I also went into the Project Settings and turned On Option Strict and Option Explicit.I also set the Warning Configurations so that "Function/Operator with no return value" was set to Error.I compiled the project and got no warning, and no error on the TestWarning() Function. This seems like a great place to put a warning, because it will default to False, and you may have simply forgotten to do a return. C# will error without a return statement. I thought that VB.NET did the same thing with the "Function/Operator with no return value" configuration. Is this a bug, or is there something I'm missing?

Edit: Further Experimentation

Function TestWarning() As Boolean
If DateTime.Now.DayOfWeek = DayOfWeek.Monday Then
Return False[code].....

If, and nothing in the Else, there is also no Warning/Error. It will simply take the default, even though you likely intended (via programming style) to have an explicit return. In this case, I explicitly returned False (which is the default for Boolean), so it's likely a hidden bug that I should have returned True in the Else.

Return A String From A Function

I have a class in this class i call a function which should return some string the class connects to an ftp server and list the directory and returns the filenames of the dir.

NPV In Excel And VB Return Different Values?

Nov 30, 2010

If a use the NPV() function in Excel (2010) with a discount rate of 5% and 10 cells that each contain 505,000 the resulting NPV function call "=NPV(5%,C2:C11)" returns the value of  3,899,496.

If I use the Financial.NPV() method in the Microsoft.VisualBasic namespace (in my C# application) and pass in a discount rate of 5% (as a double) and an array of 10 doubles with a value of 505,000 each, the VB function returns the much lower value of 100,999.99 (plus a few more decimals).

.NET : Generic Function To Return A Control?

Oct 14, 2010

I have created a couple of simple functions in VB.NET that simply return a control of a certain type that I already know, such as HtmlInputHidden, Label, etc. That means that each of the functions is created only for that special purpose. What I'd like to do is combine all those functions into one function using generics. The common things shared by each of the functions is a control Id and a control type.What I have got so far is:

Public Function GetControl(Of T)(ByVal ctrlId As String) As T
Dim ctrl As Control = Me.FindControl(ctrlId)
If (Not ctrl Is Nothing) Then

[code]....

But the line " GetControl = CType(ctrl, T)" is giving me a compile error:

Value of type 'System.Web.UI.Control' cannot be converted to 'T'

This is in .NET Framework 2.0.

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.
