AW: [pro_vb] Array problem




A possible way is to dim a boolean like that


Dim bolListSelect as boolean
Dim i As Long, ctr As Long
ctr = 0


For i = 1 To lvcons.ListItems.Count
    If lvcons.ListItems(i).Checked = True Then
    ReDim Preserve arrTmpIDs(ctr)
    arrTmpIDs(ctr) = lvcons.ListItems(i).Text
    ctr = ctr + 1
    bolListSelect = true


    End If
Next


Now you have got a True or false

Hi,
This is really  a no brainer.. and im brain dead at the moment. :o)
I have treeview with check boxes.The user check boxes the wants, and then
click an ok button.When he does this i loop through the nodes and add the
item to an array.
Since i dont know in advance how many checkboxes the user will select, im
using  a dynamic array.
which im setting using  a counter in the loop and redimming it again.


Dim i As Long, ctr As Long
ctr = 0


For i = 1 To lvcons.ListItems.Count
    If lvcons.ListItems(i).Checked = True Then
    ReDim Preserve arrTmpIDs(ctr)
    arrTmpIDs(ctr) = lvcons.ListItems(i).Text
    ctr = ctr + 1


    End If
Next


Now the probelm is if the user doesnt select any checkbox, my ubound call at
the next form bombs.
What i need is a way to findout if the array is undimensioned.. any function
to do that or a workaround??
Thanks
Satya
