My plan is to edit an Associative array entity  Programmatically and I don't know where to start.

Why can't I cast a DBobject to AssocArray ?

something like this?

Dim myarray As AssocArray = TryCast(mydbobj, AssocArray)

Why TypeOf  dbobject  is BlockReference ?

Can I get some right direction Here Please? I stuck right at begining.

Thanks Janet.

I haven't played with them yet, but if memory serves, I think Stephen Preston did a DevCast on the subject.

A quick search gave me this Through the Interface Post:

http://through-the-interface.typepad.com/through_the_interface/2011/11/creating-a-simple-associative...

Which also points to this TTIF post:

http://through-the-interface.typepad.com/through_the_interface/2011/03/new-apis-in-autocad-2012.html

The second post has links to download the DevTV session.

Hello chief, 

Thanks for reply and helping me again .

I saw that and I was able to create them using that link. Now question is how could I edit them after they added to database. Because after I get DBobject  I can't even cast them to get the proper  class.

Hello Chief . I knew you never make mistake. That is why I double check the second Link which was TTIF post. and I found what I want. Thanks again. Sorry I rushed to answer at first place.

Regards,

Janet.

Oh, believe me, I make mistakes.  Glad this wasn't one of those times.

Here is one approach but might be a better way of doing it

but

AssocArray.GetParameters

modify parameters
