Pulling row numbers out of tables.

Question

I have been looking for different ways to pull row numbers from tables.  There appears to be two main methods, one of which works for me and the other that does not.  The first is:
NameDataSet.Tables.Rows(0).Count
This gives me the number of rows in a table.  The problem is that I have a number of tables and it appears to just pick one of them to display (I set the code above up in a
MessageBox.Show().
The second is the one I think I would like to use but I get an error with it.
DataTable.Rows.Count
In this case it won't accept the table and states that the table is not declared.
I have looked up everything I can, but much of it makes no sense to me and that which does I seem to be unable to make work.

OK, here is what I want to do.  I have an add record event that has a method inside for creating a directory in a specific location with a name that corresponds to the number of the last record in the table.  So I need to extract that number in
order to create the directory (actually, it gets created anyway, just the wrong name).  Previously when I clicked the add record button the first line of code was:
Dim txtFileAdd As String = Me.TblFMFileMasterBaseBindingSource.Position
This used to work, but now, for whatever reason, this always puts me at the first record (possibly due to the binding navigator, but don't know why).
So I ended up modifying slightly what you gave me:
Dim txtFileAdd As String = Me._MasterBase_06DataSet.tblFMFileMasterBase.Rows.Count + 1
Which gives me the exact count I need to then go ahead and create the directory I want.
Hope that clears up you confusion, at least a little.
