is array redimmed?
 

Hi All.

I want to use a one dimension dynamic array, so my declaration is:

Dim myarray()

Redim myarray(x) changes it to a real array.
But how can I determine the state of myarray when it was not redimmed yet .

Thanks,
Stefi

Dear Stefi

May be you can check the number of dimensions using the below proc. and if
it is 0 you can Redim...

Dim myarray()
If GetNumberOfDimensions(myarray) = 0 Then
ReDim myarray(10)
End If


Function GetNumberOfDimensions(arrTemp) As Long
On Error GoTo ErrHandler
Do
intTemp = intTemp + 1
ErrorCheck = UBound(arrTemp, intTemp)
Loop
ErrHandler:
GetNumberOfDimensions = intTemp - 1
End Function

The problem is that ISArray() returns TRUE either after Dim myarray() or
Redim Preserve myarray(x). I want to determine that Redim Preserve
myarray(x) has already been issued or not.

ISArray() will return TRUE

Dim myArray()
Msgbox IsArray(myArray)

the problem with the REDIM() statemtn it is may create an extra item in the
array. For example
Redim A(5) really create 6 items 0 to 5.

If you specfiy
Redim(0 to 4) this will create only 5 items

Also use Preserve so you don't loose you old items after redim

Redim Preserve A(5)

I would test if the array already exits bu use a counter to keep track of
the number of items or use UBOUND to get the upper limits of the array.

You could also make the array size 1 at the beginning of the code
Dim A as variant
Redim A(0 to 0)

Redim doesn't change the variable to a real array it creates a second
variable with the same name as an array.

You should declare the variable as a variant so you don't have two variables
with the same name

from
Dim myArray()

to
Dim MyArray as Variant 'note - no parenthesis

You might get a more useful answer if you told us what it is you are trying
to do (that is, why are you trying to check the state of MyArray and what
will you do when you find out).
