Hashtable does not work correct

[corwin42]

I wanted to port a hashtable from agrahams collection library to the internal hashtable and found out that it doesn't work correct.
I think the problem is removing an item:

Sub App_Start
 hashtable1.Add("apple", "green")
 hashtable1.Add("ball", "blue")
 hashtable1.Add("train", "black")
 Msgbox("Train: " & hashtable1.Item("train"))
 hashtable1.Remove("ball")
 ' This gives an out of index error!
 'Msgbox("Train: " & hashtable1.Item("train"))
 hashtable1.Add("ball", "yellow")
 Msgbox("Train: " & hashtable1.Item("train"))
End Sub

First MsgBox says "Train: black" which is correct.
Second MsgBox gives an out of index error.
Third MsgBox (after commenting out the second one) says "Train: yellow" which is wrong.

BTW: If I try to use the hashtable from agrahams collection library I cannot compile because it gives an error of duplicate object "hashtable".

Greetings,
Markus

I don't know how the data is saved internally but would it be possible to implement an Update(key, value) method? Currently I have to do a Remove() and then Add() to update the value of a key.

I like the Update idea and it will be added.
A new release will be available tomorrow with a fix to this bug.

Once the new release is official I will probably reissue the Collection library with the collections renamed something like HashTableEx, StackEx etc. to avoid name conflicts.
