Passing A Constant Array To A Function?

Jul 23, 2009

pass an array to a function, like the code below shows

Private Sub SomeFunction(ByVal PassedArray() As String)
For i As Integer = 0 To PassedArray.Count - 1
Debug.WriteLine(PassedArray(i))

[code]....

But is there a way to pass a constant array to a function in VB .Net, for instance in PHP you could write

function SomeFunction($array)
{
for($i=0;$i<count($array);$i++)
{

[code]....

So to reiterate: Is there any way to pass a constant array directly to a function in VB .Net? Is there any benefit in doing so? I imagine a few bytes of memory could be spared.

PS.SomeFunction({"some", "array", "member"}) ' this obviously gives a syntax error

Passing An Array Of Integer To An Array Of Object In A Function

Mar 4, 2012

I am creating a dll with all the functions and subroutines that I use all the time and I decided to create a function that I can pass different types of array to so the function obviously (or not) would have an array of type object. Now I no you can pass any type into an object type but when I pass an integer array into an object array I get an error.

value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.

Shared Function CompareArray(ByVal FirstArray() As Object, ByVal SecondArray() As Object, Optional ByRef ErrorMessage As String = "") As Boolean
Dim IntArrayOne() As Integer = {1,2,3,4,5} Dim IntArrayTwo() As Integer = {1,2,3,5,6} Dim IsSame As Boolean = False IsSame = CompareArray(IntArrayOne(), IntArrayTwo())

Passing The Result Of An Array-Valued Function From A Fortran95?

May 25, 2011

I am interested in developing a multi-language program that will have a main .NET GUI but will perform calculations by calling procedures from a Fortran95 dynamic link library file. Right now I am just playing around with a very simple project in order to get the interoperability between the .NET framework and a Fortran95 (*.dll) file working correctly. So far, I've been able to pass the Fortran95 (*.dll) file an array from VB, sum all the elements of the array using an intrinsic Fortran function, and pass the scalar result back to the .NET framework with no problem. However, if I try passing Fortran the exact same array, construct the transpose of that array using another intrinsic Fortran function, and try passing the transposed array back to the .NET framework I keep throwing an exception. I am not a programming wiz, but it appears that when Fortran stores an array in memory, the .NET framework doesn't know how to read that. I am looking for some guidance on how to pass an array from the Fortran95 (*.dll) file back to the .NET framework.

Named Constant For InputBox Function

Reading Named Range Into Array - Constant Expression Required

Mar 11, 2011

I need to read a named range into an array. Then if the value in the 1st position matches a static value, read the value in the second position. I've been looking into array's and this is what I think will work, however I get a compile error on the columns.count "constant expression required". Is it because in the DIM statement I'm attempting 2 things? This is a macro in Excel. The range name is Data1 and the string comparison is "AnyString". The second value will be an integer.

Sub macro1()
Dim rng As Range
Dim x As Integer
Dim y As Integer

Public Constant Versus Private Constant?

Aug 13, 2011

When building a class library which contains many classes, all classes uses a lot of common constants and functions, what is the best to do:

1- Declare these constants and functions as public in a module.

2- In each class declare constants and functions used by individual class as private.

The first choice is good for easy and fast implementation, but re-using a class in a different project will require importing the module to the other project.The second choice require a lot of copy/paste for code snippet but a class can be re-used in different project easily.

Passing A Value To A Function?

Mar 22, 2011

I have a question concerning some homework. Here is my answer:

Dim intResult As Integer
intResult= Square(4)
lblResult.Text = CStr(intResult)

Now, if I understand functions correctly, this statement should pass the value 4 to:

Function Square( ByVal intValue As Integer ) As Integer
Return intValue^2
End Function

...and assign it's return value to "intResult".

Passing A List's Enumerator To A Function

Dec 2, 2011

It looks like passing a list's enumerator to a function "byval" is quite different than passing it "byref". Essentially, regular "byval" passing will NOT change the caller's "enumerator.Current value", even if the function advances the enumerator. I was wondering if anyone knows why this is the case? Is an enumerator a primitive like an integer, without an object reference, and hence changes to it don't get reflected in the caller?This function is byval, and gets stuck in an infinite loop, spitting out "1" message boxes, because the enumerator's "current" never advances past 5.[code]The difference between the two functions is only whether the listFirstItem__ function accepts a byval or a byref enumerator.
