# ProgIDs

To specify a new programmatic identifier for this COM server, right-click the ProgIDs item in the explorer, and then click New ProgID. (The New ProgID command is not available if the COM Classes area is empty.)

A ProgID is a string used to identify a class in the format Component.Class.N. To rename the ProgID, right-click it and then click Rename, or press F2.

Select the ProgID to set its properties, including its associated COM class, description, icon file, and icon index.

To create a version-independent ProgID, right-click an existing ProgID and then click New Version-Independent ProgID.

The recommended way to specify file registration is to use the Component Wizard and have it automatically extract the necessary information for you. Edit the COM registration here only if you need to make advanced modifications.
