.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?

I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

Initialising An Array Of Structures

Nov 7, 2009

I have a Structure, and I am having trouble initialising it. Specifically when I try to populate the Vector3 variables, it tells me that they are Nothing, so I need to make them New when the array of this structure is declared.[code]Structures cannot declare a non-shared 'Sub New' with no parameters.I have no parameter to supply, and this will be an array so I'm not even sure how I would supply it.The second option to fix the error is to make the Sub New shared, but then I get other errors: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.Does anyone know how I can resolve this. My end goal is to have an array of this structure type with the Vector3s ready to use.

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.

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

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]...............

Function That Converts A String With Spaces To An Array?

Since almost all the functions that are in VBcript are in VB.NET I was wondering if anyone remembered the name of the function.

Change Function To Build Byte Array Rather Than Concatenating String For TCP Sockets?

Jan 5, 2010

I've been trying to reuse my bosses vb.net buildpacket code which he has successful used for Serial programming eg. SerialPort1.Write(buildpacket(useraddress,252,"0006","0") for the function listed below.My challenge.Create equivalent functionality for Socket BeginSend() which requires a byte array.Whether modifying the vb.net below or getting a c# equivalent to work, it has been repeatedly recommended to scrap the string concatenation approach for which I have to use Encoding.BigEndianUnicode.GetBytes() and then getting rid of extra bytes with zero values.

I'm lacking in imaging something different which would work for socket programming directly and allow me to eliminate all the hassles that c# integer conversions into string value that can be encoded trouble free.I would need to call the equivalent of the following that would return a byte array rather than a string with the following arguments

1. Source address (0-255)
2. Destination address (0-255)
3. Function code ("0001" through "0100")
4 Packet Data Unit (pdu - some integer value

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)

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
