Keep AutoCAD hidden while zooming by VBA

[MSasu]

I have the following scenario: call AutoCAD in background (hidden) from a stand-alone process (a Visual Basic application), perform some draw operations and call Zoom Extend just before save in order to have the entire content shown. What I’m trying to achieve is to keep AutoCAD window permanently hidden from user to ensure that he don’t close it or intervene in processing accidentally. But using zooming while the window is not visible it will raise a fatal error so I’m forced to bring it back visible for a while.

 

Is there a way to perform a Zoom Extend operation while still prevents the user to see or interact with AutoCAD’s main window? Thank you!

 

Regards,

Look at your code can you speed up the process if its visible ? Often here in lisp people provide code does same thing and is so much faster should be same in VBA.

 

There may be something with turn off Regen just not sure.
