I'm having two issues. The blocks get updated with the new definitions, but the new versions of the blocks are not being represented ( a regen fixes the problem ), and the new attributes are not showing in the correct location ( a move fixes the problem ).
I thought that if you made the database the working database then the attributes would be updated correctly? This does not seem to be the case when a drawing is opened but not current. How can I fix this?
I have used the draw method on the block references, and they update nicely in the current open drawing, but not in a non-current drawing. I have tried to use the QueueForGraphicsFlush method of the TransactionManager, but that doesn't work unless it is the current document, at least that was the error I got. I tried the Regen method of the Editor, but that only regened the current document. Does anyone have any other suggestions?
Its for Acad '09, and .Net 2.0
Let me know if I didn't provide enough information. Thanks in advance.
