• cdbob Handles on a 64 bit OS

  From a MS white paper on 64 bit computing, it appears that a handle for a 64-bit application can be used by a 32 bit process.

  Hi - I have created a class that derives from Hashtable whose items are arraylists, creating a multimap of sorts for which I can iterate through all the items of the same key. I have overwritten the set_Item property method so that adding an item always places it in the arraylist for the given key. I am having trouble with the get_Item method though.
