array is a group of similar variables, combined for organization and easier access to this particular group of variables.

Dim MyArray (9) as String

will declear 10 string varaibles called MyArray(0), MyArray(1) ... MyArray(9)

You can also specify the range of the array:
Dim MyArray(1 to 10) as String
This will result in declaration of variables MyArray(1) ... MyArray(10)

Now you can use each variable just by using the name and desired position of the array. Such as MyArray(1) will use first variable in the group and MyArray(10) will use 10th.

The best and mose useful part of the array is that you can pick a variable based on yet another variable.

MyArray(index)

will use a variable MyArray with position in the array determined by variable index. So if index is 1, then MyArray(1) would be called. If index is 10, then MyArray(10) will be used.

This is useful in cases where the user or the program picks what variable to use. So instead of writing up 100s of IF statments, an array would be a better choice.

How would I initialize an array (like init in Turing), instead of having to go
MyArray(1) = "blah"
MyArray(2) = "blahblah"
MyArray(3) = "blahblahblah"
thankyou

I guess if you wanted each to have one more "blah" than the last you could make a loop do that

Dim X as Integer
MyArray(1) = "Blah"
X = 2
For X = 2 to 10
MyArray(X) = MyArray(X - 1) & "blah"
next X

sorry, i meant the extra blahs to show a difference between the different elements of the array. i should have put different names for each array element.

May sound cheap but often times in VB it is actually easier to place a listbox on your form and set visible to false. You can load the listbox at design time with the List property, you can set it to be automatically sorted. You can add and remove elements without worrying about using redim.

When you create a control array how do you set up a Select Case Index?

-----------------------------------

not sure what you're asking, but in a control array all events will have

(index)

as their parameter. Such as

sub Buttons_Click(index as integer)
Buttons(index).Caption = "you clicked me"

Thanks, I figured it out.  Sorry for the confusing description of what I needed explained, that was the best I could describe it from what I'd been told I needed to do

dim intCount as integer, intLotto(1 to 6) as integer

For intCount = 1 To 6
        Randomize
        intLotto(intCount) = Int(Rnd() * 49) + 1
        picOutput.Print intLotto(intCount);
Next intCount

what i wanna do i like sort the output for example, 5 17 25 28 41 47 etc.
