## How to define an Array?

(OP)
Hi,

I would like to know how can I define an Array in VB (Excel)?

I tried the following commands:

Dim myArray(5) As Integer

myArray = Array(12,3,13,64,245,75)

But, I got a compile error as follows:

Can't assign to array

Please let me know what is the proper way for defining an Array?

Thanks,
A.A.Y.

### RE: How to define an Array?

The two statements don't work together.

You can either use:

#### CODE

myArray = Array(12, 3, 13, 64, 245, 75)
' (no dim statement)
' won't work if option explicit is included

Or else you can use:

#### CODE

dim myArray(5) As Integer
myArray(0) = 12
myArray(1) = 3
myArray(2) = 13
myArray(3) = 64
myArray(4) = 245
myArray(5) = 75

Or dimension the array as a variant (which is the default if you don't dimension it).  Then you can leave the Option Explicit statement in place.

You can also transfer the contents of a worksheet range to an array:

#### CODE

Dim MyArray as Variant

MyArray = Range("MyRange").Value2

Note that:
1. The array is automatically re-sized to the size of the range, so you don't need to specify the array size (in fact it won't work if you do).

2. Use .Value2 rather than .Value (the default) or nothing because it is quicker and it won't truncate values formatted as currency to 4 decimal places.

3.  All arrays will be 2D, base 1, so a range of 1 row x 10 columns will come in as MyArray(1 to 1, 1 to 10).

No, that doesn't work for me.  The following code gives an error ("Compile Error: Can't Assign to Array"):

#### CODE

Dim myArray(5) As Variant
myArray = Array(12, 3, 13, 64, 245, 75)

Pete - you didn't read my notes!

Either
Dim MyArray as variant
or
Dim MyArray() as variant

will work.

The array is automatically redimmed when you assign something to it.
