Hi,

I implemented some code to save the list of all XRefs in a drawing, and I need to know which XRefs have been added/removed when closing that same drawing.

 

To do this, I tried catching both the BeginClose and EndSave Doc Events.

 

Unfortunately, if I add an XRef to a DWG, the new XRef does show in the blocks collection. OTOH, if I delete an XRef, then the deleted XRef still shows in the Blocks collection, disappearing only when I re-open the drawing.

 

How do I know that the XRef has been deleted when I close the file?

 

Thanks,

M
