HI ALL
TAKE CARE: Nothing was working in VB6, but in .NET it sets the default value !
from help of VS.
When you assign Nothing to an object variable, it no longer refers to any object instance. If the variable had previously referred to an instance, setting it to Nothing does not terminate the instance itself. The instance is terminated, and the memory and system resources associated with it are released, only after the garbage collector (GC) detects that there are no active references remaining.
Garbage Collector distroyes the objects at the end of the sub of function, not in the loop.
So use local variables when you loading the 7000 items. For me working fine and i do not have a memory problems. I am loading 50000 items with prices from EDI file, and memory usage stops at 120MB.
1st solution  create a sub or a function to populate the data, and run this for every items by as single rutin,
  sub x
    Dim obj As New Object()
        Try
... put here your update code
        Catch ex As Exception
        Finally
            GC.Collect()
        End Try
  end sub
This free up the memory when Garbage
2nd solution: use inner loop definition
  sub x
Try
            Do While True
                Dim obj As New Object()
            Loop
        Catch ex As Exception
        Finally
            GC.Collect()
        End Try
  end sub
This free up the memory inside the loop.
I recommend to use Friend Class keyword for your addon declaration and do not use modules.
Modules and shared classes will be free up the memory when your program terminates execution.
