Lock a Layer

Locking a layer is easy enough - I believe its oLayer.Lock = True. You
could then try finding out if an event is fired whenever a layer is
unlocked, test for your layer name and relock it. You could also check
the endcommand event, test to see if it was one of the layer commands
and, again, test the status of your locked layer. Not sure if these
suggestions will work, but that's what I'd try.

Hi.
I'd like to know if is possible to lock a layer and deny users to unlock
it.
Does anybody know how to do it or just if it's possible ?

Thanks,

Ralf Davi.

 

Well you didn't state you were going to send this somewhere. If that is
the case you have two options: export or third party

Export - save the file to dwf, pdf or another file type
3rd Party - look at CADLock or another security tool

No, for this one customer you can embed the macro with the drawing.

Joe

 

Yeah, he could, but it isn't secure - that's why I didn't list it as an
option.

Maybe this would work, but it will work just for the AutoCAD that have
this macro running.
Now, imagine that I wann send the document to my client and he cannot
change one of three layers. He hasn't the macro running on his machine.
I think that I have to do it in the document...but have no ideia...

 

can you use an embedded dvb? then it's in the dwg.

 

Put a password on the DVB.

Joe

 

Sure but it depends on the level of security he wants. Its way too easy
to crack a dvb password. I guess he never explained why he wants the
security. If he's worried about a liability/legality issue with the
client, I'd still pursue the first two opts I gave. If its just a 'don't
touch our stuff' thing, embedding the dvb w/ a password would fulfill
his need. I had 'read' the first case into his request.

My personal vote is for the PDF, but then like you said, he may have a
reason for allowing them to access the actual DWG file.

Joe

 

But I don't understand how can I embed a macro with the drawing ?
Can u explain me better ?

 

To embed:
vbaman at the command line.
Select the vba project from the list
Choose embed.

Embeded projects require the permission of the one
opening the drawing to enable the macros. So this
is of little value if you are trying to force the user to
behave a certain way.
