Choose

[LucaMs]

I wanted to post some snippets to help us all.

So I went to look through the VB.Net functions, hoping to find some for B4A.

This is beautiful, very useful (unfortunately the description is in Italian):

warning: DO NO USE SOMETHING LIKE:

Dim MyArray() As String
...
Dim Word As String = MyArray(4)

USE:
Dim Word As String = Choose(4, MyArray)

Hi Lucas,

Can you elaborate? Perhaps translate the function to English?

I had too much hurry (as usual )
It could be useful in rare cases.

Choose(Index As Double, ParamArray Choise() As Object) As Object
Selects and returns a value form a list of parameters.
Index: Needed. Double. Numeric expression - must be a number between 1 and the number of elements of Choice.

But Choice is not an Array, it is a ParamArray. This means that you could use:

Dim Obj As Object = Choice(4, "Hello", 5, lvwItems, ... )

Not to be a spelling Nazi but, the word is CHOICE not choise.

Well, you are right but I had written two "choice" and two "choise", so you would have been able to make your... choize
