Can you make two dimensional arrays in vb?

i want to make an array with 2 rows and 5 cols

how would i do that?

thanks

Thanks Jeff

now lets say I had an array of Test(2, 2)

meaning it has 2 rows and 2 cols
And I set
test(0, 0) = "X"
test(0, 1) = "X"
test(1, 0) = "X"
test(1, 1) = "X"

How would I print this on the form using a for loop so it comes out like this
XX
XX

Try something like this:

Dim sVal As String

For i = 0 To 1
    For j = 0 To 1
        sVal = sVal & test(i, j)
    Next j
    sVal = sVal & vbCrLf
Next i

MsgBox sVal

Or, if there are always 2 columns:

Dim sVal As String

For i = 0 To 1
    sVal = sVal & test(i, 0) & test(i, 1) & vbCrLf
Next i

MsgBox sVal

By the way Savok an array declared as: Dim Test(2,2) As String will actually have Three Rows and Three Columns and the index of either dimension can run from 0 to 2.

And now somebody will reply: true, unless you specify Option Base 1 at the beginning of your module, in which case the index will run from 1 to 2. Well, most of the time, because the said Option Base 1 will NOT stop some functions returning arrays that are Zero-based: most noticeably the Split Function. _________________________________

rvBasic,

... but you could also use

The subscripts argument uses the following syntax:
[lower To] upper [, [lower To] upper] . . .

... then all of the preceeding are sbject to interpertation. but then your original statement is 'good enough' for thislevel of inquiry/response.

I would agree with everything that rvBasic and MichaelRed posted. Just my 2 cents so to speak . . . - Jeff Marler B-)
