ASSOCIATIONLEVEL enumeration (shobjidl_core.h)

Specifies the source of the default association for a file name extension. Used by methods of the IApplicationAssociationRegistration interface.

Syntax

typedef enum ASSOCIATIONLEVEL {
  AL_MACHINE = 0,
  AL_EFFECTIVE,
  AL_USER
} ;


`AL_MACHINE` Value: 0 The machine-level default application association.
`AL_EFFECTIVE` The effective default for the current user. This value should be used by most applications.
`AL_USER` The per-user default application association. If this value is used and no per-user default is declared, the calling method fails with a value of `HRESULT_FROM_WIN32(ERROR_NO_ASSOCIATION)`.
