Command line: vbaload
Disables macro viruses. A macro virus is a type of computer virus that is stored
in the macros of a VBA project. If you open a drawing or project file that
contains macros, a macro virus can become active and be transmitted to your
computer. From that point on, every drawing or project file you save can
become infected with the macro virus. When other users open the infected
drawing or project file, the macro virus can also be transmitted to their
computers.
The AutoCAD Macro Virus Protection dialog box that is displayed when you
open a drawing or project file that contains macros gives you the opportunity
to disable the macros. A macro virus can be harmful only if it is allowed to
run. If you disable the macros, you can open the drawing or project file safely.
The AutoCAD Macro Virus Protection dialog box provides the following
options:
Always Ask Before Opening Projects with Macros
When cleared, prevents the AutoCAD Macro Virus Protection dialog box
from being displayed again. You can later enable macro virus protection
using the VBA Options Dialog Box, available from the VBARUN command.
Disable Macros
Loads the drawing or project file with the macros disabled. Use Disable
Macros if you do not expect the drawing or project file to contain useful
macros, or if you aren’t certain about the reliability of their source.
Once you disable the macros, you can’t run any macros. However, you can
still view, edit, and save the macros. You can close the drawing or project
file later and open it again with the macros enabled.
Do Not Load
If you are loading a project file, the process is canceled and the project file
is not loaded. If you are opening a drawing with an embedded project, the
drawing is opened with the macros disabled.
Enable Macros
Loads the drawing or project file with the macros enabled. Use Enable
Macros if the drawing or project file is from a reliable source, or if you expect
the drawing or project file to contain useful macros.
VBAMAN
Loads, unloads, saves, creates, embeds, and extracts VBA projects
