RegisterExtensionInfo Action
The RegisterExtensionInfo action manages the registration of extension related information with the system.
Sequence Restrictions
The RegisterExtensionInfo action must come after the InstallFiles action and the UnregisterExtensionInfo action.
The sequencing of the actions in the following group is restricted. If any subset of these actions occur together in a sequence table, they must have the same relative sequence order as shown:
- UnregisterClassInfo
- UnregisterExtensionInfo
- UnregisterProgIdInfo
- UnregisterMIMEInfo
- RegisterClassInfo
- RegisterExtensionInfo
- RegisterProgIdInfo
- RegisterMIMEInfo
For example, RegisterExtensionInfo must come after UnregisterMIMEInfo in the sequence table.
ActionData Messages
| Field | Description of action data |
|---|---|
| [1] | Registered extension. |
Remarks
If the system supports installation-on-demand for extension servers, RegisterExtensionInfo registers all extension servers in the Extension table associated with features set for installation or advertisement. Otherwise this action only registers extension servers associated with features set to installation.
