Function To Return Array?

Aug 5, 2011

Before adding rows to a table I am evaluating the SSN number. These will later be flagged for correction so I am setting a datatable column to true or false if it passed muster or not.

I wrote a function to check the number and make the determination plus pad it with zeros and hyphens where they should be. My problem is I want to return the results in an array. I am getting system.string[] as the return value.[code]...

Return An Array From A Function To The Original Sub?

Oct 14, 2009

I'm trying to call a function from a sub, and have it return an array to the original sub.

I currently have:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call Registry_GetUsers()
End Sub

[code]....

Which works, but I want to loop through each of the items in users from within the original sub, not the function, as it currently does.So I need to return the array to the original sub, so I can then iterate through it from there.

.net - Return A String Array From A Function Without Initialising It First?

Dec 10, 2009

Public Function Foo() as String() Dim bar As String = {"bar1","bar2","bar3"}

Return bar End Function

My situation is similar to the code sample above where I'm returning a string array from a function.

What I would like to do is just return the string array without having to declare a variable first and then return the variable.Something like this, although this obviously doesn't work:

Return {"bar1","bar2","bar3"}

Is it possible to do this, I can't seem to find a method that works?

Customer Class - Return Array In Function?

Apr 12, 2009

I have a class called Customer. It has some property like custID,custName..etc. Inside Customer class I have a function which returns an array of customer.

I wrote a function like this :
Public Function InitLoadCustomerDetails() As Customer()
sql = "SELECT* FROM tblCust"
ds = classDC.queryHandler(sql, "InitCustomerDetails")
Dim customerArray(classDC.maxrow - 1) As Customer
Dim currentCustomer As New Customer
[Code] .....

But it is not returning an array. Just a customer variable??
Public Function InitLoadCustomerDetails() As Customer()
Return customerArray
End Function
Fix this to return an array of customer!!

Run The FindPath() Function 2000 Times, And Return The Resulting List Of Moves Into IntLists()(), My Jagged Array?

Mar 31, 2009

I'm working on a program dealing with jagged arrays.Code is below.The FindPath() function works perfectly.It essentially randomly chooses an action from 3 possible choices.The goal of this function is to make it to position (3,3) from (0,0).Sometimes it makes it, sometimes it doesn't.It gives up after 2000 moves.

The PushButton() function is where I have the problem.I want to run the FindPath() function 2000 times, and return the resulting list of moves into intLists()(), my jagged array.I want to use

intRuns = 0
For intRuns = 0 To intLists.GetUpperBound(0)
lstMoveList.Items.Add(intLists(intRuns).GetUpperBound(0)) 'here is where I get the problem.

this section of code to dump the number of attempts it took into a listbox on the main window.I do this at the bottom of the FindPath() function, but that is for testing purposes only.I eventually want to take the successful attempts and manipulate those, so eventually I get the minimum possible number of movements to get from the starting point of (0,0) to the ending point of (3,3).

Function PushButton()
Dim intRuns As Integer
Dim intLists(2000)() As Integer[code]...............

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?

Feb 12, 2010

take a look at the following Code:

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

[Code]....

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.
