Well, maybe, but that doesn't answer my question. Did you try setting the
listbox invisible while it's loading the data?
That really really helps. Look:
dim start,ittook as double
self.Listbox1.DeleteAllRows
start=Microseconds
Self.Listbox1.Visible=false
for i as Integer=0 to 10000
Self.Listbox1.AddRow("A","B","C","D")
next
Self.Listbox1.Visible=true
ittook=Microseconds-start
MsgBox("It took "+str(ittook/1000000)+" seconds")
This code populates the listbox in 0.08 seconds on my 2,66 Ghz MacBook. That's
not slow. It does take half a second if you don't set the listbox invisible.
