I know C++, and using it allows me to create arrays.

Is it possible to create arrays in VB and please give me a simple code so I can create an array with 10 string elements.

Thank you.

Hi digi_mind,
Dim MyArray(10) As String
DIm i As Integer
MyArray(0) = "String0"
MyArray(1) = "String1"
MyArray(2) = "String2"
MyArray(3) = "String3"
MyArray(4) = "String4"
MyArray(5) = "String5"
MyArray(6) = "String6"
MyArray(7) = "String7"
MyArray(8) = "String8"
MyArray(9) = "String9"

(could be done in a for next loop)
for i = 0 to 9

Hi digi_mind,

Dim aryMyArray(10) As String

You then have an array with ten elements (0 - 9) that you can refer to like this:

aryMyArray(0) = "Hello"
aryMyArray(7) = "Goodbye"

Sorry, submitted before I meant to!

(could be done in a for next loop)
for i = 0 to 9
MyArray(i) = Some Data
Next.

or even
Dim MyArray
Myarray = Array("String0", "String1","String2","String3","String4","String5")
Dim i
For i = 0 To 5
msgbox Myarray(i)
Next

you can also create dynamic arrays:

dim MyArray() as string

'then you can redim it later on

Redim MyArray(10)

For i = 0 to 10
MyArray(i) = "Hello"
Next i

'then if you want to add a few more...

Redim Preserve MyArray(20)

For i = 11 to 20
MyArray(i) = "Good Bye"
Next i

>>Dim aryMyArray(10) As String
>>You then have an array with ten elements (0 - 9) that you can refer to like this:

That is NOT correct. That gives you eleven elements (0-10).

As stated in the MSDN Library:
Dim Counters(14) As Integer
Dim Sums(20) As Double

The first declaration creates an array with 15 elements, with index numbers running from 0 to 14. The second creates an array with 21 elements, with index numbers running from 0 to 20. The default lower bound is 0.

No comment has been added lately, so it's time to clean up this TA.

No split, mind you 20 points is hardly enough to split anyway so don't worry about it.
