Array inside array

[tatchung]

Hello everyone, Is it possible to store an array inside an array? Like for example I have these logs below array1(0) 2007-05-17 04:25:30 Receive 2007-05-17 04:25:31 Sent 2007-05-17 04:25:31 Sent 2007-05-17 04:25:34 DLR array1(1) 2007-05-17 04:32:18 Receive 2007-05-17 04:32:19 Sent 2007-05-17 04:32:19 Sent array1(2) 2007-05-17 04:37:03 Receive 2007-05-17 04:37:04 Sent 2007-05-17 04:37:04 Sent 2007-05-17 04:37:04 Sent Then for each array1 element I can create another array (array2) to store each line separately for "Received", "Sent" and "DLR". So I was thinking it would look something like array1(0(array2(0)). Many thanks in advance for any help, suggestions given :-D

Not quite. An array is an object, so it doesn't have a name in itself. What you name is the reference variable that holds a reference to the array. So, you don't name the arrays that you store in the array. You only have a name for the variable referencing the outer array:

Dim array1(3)() As String
array1(0) = new String() { "Receive", "Sent", "Sent", "DLR" }
array1(1) = new String() { "Receive", "Sent", "Sent" }
array1(2) = new String() { "Receive", "Sent", "Sent", "Sent" }

You can create a string array to store in the array. You would have a reference variable for that array too, but you still only store the reference to the string array in the outer array:

Dim x(1) As String
x(0) = "Receive"
x(1) = "Sent"
array1(3) = x 'Puts the reference in the outer array

To use the arrays you only use the single variable name that you have. The value of the expression array1(0) is a string array, so you just stack another index after that expression to access a string:

array1(0)(1)

Despite everything, the person most likely to be fooling you next is yourself.

Aha! So i just have to add the element number of the inner array when i call upon the outer array. Many thanks Sir! Sorry about this but I forgot to mention I'm using vb6. Is this still applicable or is this already for .NET?

It should work just fine in VB6, but the syntax isn't exactly the same. It's called a jagged array if you want to look for code examples.

Great! That just changed my views. :-D Got the code and it looks something like this:

Dim aTest(1 To 2) As Variant
Dim bTest(1 To 1) As Variant
aTest(1) = 1
aTest(2) = 2
bTest(1) = aTest
MsgBox bTest(1)(1)
MsgBox bTest(1)(2)

...for future reference. ;) Thanks again for the help, not to mention the enlightenment :laugh:
