Visual Basic Reference
Represents the license key and programmatic ID (progID) of a control.
When adding a control that requires a license key to the Controls collection, you must first add the control's license to the Licenses collection. Using the Add method, each pair of license key and progID become properties of the LicenseInfo object.
To determine the license key and progId of each control, use the For Each statement with the LicenseInfo object, as shown below:
Dim li As LicenseInfo For Each li in Licenses Debug.Print li.ProgID, li.LicenseKey Next
