Unlimited Array in Visual Basic 8

[Joe]

hi. simple question: how can one declare Array (or table) with unknown
number of elements, and then assign values to it, example:

Dim TableStrings() as String

TableStrings(0) = "first value"
TableStrings(1) = "second"
TableStrings(2) = "tird" .... etc
?

You may want to use 'System.Collect ions.Generic.Li st(Of T)'.

Joe,

I'm a very fresh beginner to VB.Net, so hopefully I won't screw this up, but
what you need to do is declare the array as you have in your example and add
a counter to loop through each value and assign it to the count value. In
psuedo-code it would look something like...

Declare your counter variable
Declare your array
For Each element in the input data
Assign the values to the array elements (Table(counter) )
'Do other processing if necessary'
Increment the counter by 1 (counter += 1)
Next element

Of course, if you provided information on exactly how you are getting the
information to place in the array, others more knowledgeable than I would be
able to provide you with some more concrete information.

ok, but later on, how can I read n-element from x element list (f.e. I
want to read 5th one?

dim i as integer = theList(4)

thank you very much, everything clear now :)

Joe,

If you are going to be using arrays, take a look at
REDIM and the PRESERVE command.

If you are going to be using arrays, take a look at
REDIM and the PRESERVE command.

Redim Preserve is very inefficent so it is be better to use a Generic.List
as Herfried mentioned or an arraylist. Both can be converted to an array
using the ToArray function.

or take a look at the array class
Dim x(1) As Integer ' create instance with one element

For i As Integer = 1 To 10

Array.Resize(x, x.Length + i) ' add some elements during runtime

Next

' to proof that it works

For Each i As Integer In x

Debug.WriteLine (i.ToString) ' writes out all zero`s for every element

Next

ofcourse you could do the above example with anny type you want

Michel,

I am 100% sure that Herfried this knows.
