How to read/count a Collection Object?

[ThomasQ]

Hi!

I'm extremely emberassed by my n00bness, but since I started using Autoit 6 months ago, I still got to a halt, when trying to use Collection Objects.

How do I count the number of Item's collected? And is there any way of looking in the collection object?

Many Thanks in advance

Thomas

Do you mean like this using .count() ?

$Dict1 = ObjCreate("Scripting.Dictionary")

With $Dict1
  .Add ( "Item 1","10")
  .Add ("Item 2","20")
  .Add ("Item 3","30")
EndWith

MsgBox(0,"object.count",$Dict1.count())

Hi! Just got back from vacation, and started on my script again. But no, I meant an Collection object, like the one you get with the _IETableGetCollection function.

Thanks in advance!

When you run _IETableGetCollection() the count is returned in @extended. See the help file. You might also get the count in a .length property, but I can't test to be sure right now.

Edit: Back in Windows land, verified .length works:

#include <IE.au3>

$oIE = _IE_Example ("table")
$oTables = _IETableGetCollection ($oIE)
$iExtSav = @extended
$iLength = $oTables.length
MsgBox(64, "Test", "@extended = " & $iExtSav & "; .length = " & $iLength)

That's actually how the UDF gets it for @extended, though you have to look inside the call a little to see it:

Return SetError($_IEStatus_Success, $o_object.document.GetElementsByTagName("table" ).length,$o_object.document.GetElementsByTagName("table"))
