IApplicationAssociationRegistration interface
Exposes methods that query and set default applications for specific file Association Type, and protocols at a specific Association Level.
Members
The IApplicationAssociationRegistration interface inherits from the IUnknown interface. IApplicationAssociationRegistration also has these types of members:
Methods
The IApplicationAssociationRegistration interface has these methods.
| Method | Description |
|---|---|
| ClearUserAssociations |
Removes all per-user associations for the current user. This results in a reversion to machine defaults, if they exist. |
| QueryAppIsDefault |
Determines whether an application owns the registered default association for a given application level and type. |
| QueryAppIsDefaultAll |
Determines whether an application owns all of the registered default associations for a given application level. |
| QueryCurrentDefault |
Determines the default application for a given association type. This is the default application launched by ShellExecute for that type. |
| SetAppAsDefault |
Sets an application as the default for a given type. For more information, see Default Programs |
| SetAppAsDefaultAll |
Sets an application as the default for all of the registered associations of any type for that application. |
Remarks
Because IApplicationAssociationRegistration is only supported for Windows Vista and Windows 7, applications that support earlier operating systems must use their preexisting code in relation to defaults when running under those operating systems. Those applications should include a check for the operating system version to account for this.
