Using ArcCatalog

Adding custom
commands
You don’t have to use VBA to
create custom commands. In fact,
in some cases, your custom
commands may require you to
use another development
environment. You can create
custom objects in any programming
language that supports
COM; see Exploring
ArcObjects for details. Custom
commands or toolbars created
outside VBA are often distributed
as ActiveX libraries (.dll
files). Before you can add a
custom command to the
Catalog, you must ensure that
either you or the installation
process by which you acquired
it registers its ActiveX DLL.
After registering the file on
your computer, you must
register the custom objects it
contains with ArcCatalog. You
can add the custom command
to any toolbar or menu.
1. Click the Tools menu and
click Customize.
2. Click Add from file.
3. Navigate to the file containing
the custom command.
4. Click the file and click Open.
The Added Objects dialog
box appears, reporting which
new objects have been
registered with ArcCatalog.
5. Click OK.
The custom commands
appear in the Commands list
for the appropriate category;
a new category may be
added to the Categories list.
6. Click Close in the Customize
dialog box.
The custom commands appear in the Commands list for the
appropriate category; a new category may be added to the list.
