Can hashtable hold a picture image?

[Noozer]

Code sample:
dim hash as Hashtable 'Declare Hashtable
....
hash.add (picOne.image, "picture") 'Error here


picOne is a picturebox added to the form at design time with a GIF image
applied.

When the add method executes I get the following error:

An unhandled exception of type 'System.NullReferenceException' occurred in
HashTable test.exe

Additional information: Object reference not set to an instance of an
object.

Can a hashtable be used to hold picture images?

Thanks!

dim hash as Hashtable 'Declare Hashtable

Replace the line above with 'Dim hash As New Hashtable()'.

Yes, it can hold references to images.

Yes, it can hold references to images.

Thanks... I should use the "intelli" part of "intellisense" a bit more... I
had the object and the key swapped in my code. Ooops.
