Existance of Handle

Hi all,

I am storing the handle of block references in a drawing. Suppose some body deletes some of the block references. But I has still the handle stored for that reference. So I have handle and I need to know whether the entity corresponding to the handle exist or has been deleted.

One method of doing this is iterate entire model space, get the handle of each entity and compare with the one desired and see whether the entity exist or not. If not means the entity has been deleted.

But is there any other direct method to find from a handle whether the entity exist or not.

Sorry I have narrated too much. I not clear then let me know.

Another method to try: HandleToObject.

 

Hi Manoj

This will return a trappable error if "AA" doesn't exist:

Dim TstObj As AcadObject
Set TstObj = ThisDrawing.HandleToObject("AA")

Cheers

 

Have you tried the HandleToObject method?

Hi JRWalker,

Sorry for late response because I was busy in some other work. I tried the same and it is working fine. Thanks for your help
