As in VB6, is it possible to create a dynamic array in VB NET and then
use Redim Preserve after knowing the index of the array? Thank you in
advance for your help.

Yes this is possible, but you may want to consider using ArrayLists in
VB.NET since they are much more efficient. A good article explaining
the performance difference may be found here:

In VB.NET each array can be redimensioned using 'ReDim Preserve'.
However, sometimes it's better to use more dynamic data structures like
'ArrayList' or 'List(Of T)' (.NET 2.0).
