  • Article

Specifies a mapping for a class ID.

Syntax

typedef enum tagTYSPEC {
  TYSPEC_CLSID = 0,
  TYSPEC_FILEEXT,
  TYSPEC_MIMETYPE,
  TYSPEC_FILENAME,
  TYSPEC_PROGID,
  TYSPEC_PACKAGENAME,
  TYSPEC_OBJECTID
} TYSPEC;

Constants

 
TYSPEC_CLSID
Value: 0
A CLSID.
TYSPEC_FILEEXT
A file name extension.
TYSPEC_MIMETYPE
A MIME type.
TYSPEC_FILENAME
A file name.
TYSPEC_PROGID
A PROGID.
TYSPEC_PACKAGENAME

Remarks

The TYSPEC enumeration and uCLSSPEC union provide mappings to a class ID. Note that TYSPEC_CLSID is the only supported value.

    typedef union switch(DWORD tyspec)
        {
        case TYSPEC_CLSID:
            CLSID   clsid;
        case TYSPEC_FILEEXT:
            LPOLESTR pFileExt;
        case TYSPEC_MIMETYPE:
            LPOLESTR pMimeType;
        case TYSPEC_PROGID:
            LPOLESTR pProgId;
        case TYSPEC_FILENAME:
            LPOLESTR pFileName;
        case TYSPEC_PACKAGENAME:
            struct {
            LPOLESTR pPackageName;
            GUID     PolicyId;
            } ByName;
        case TYSPEC_OBJECTID:
            struct {
            GUID     ObjectId;
            GUID     PolicyId;
            } ByObjectId;
    } uCLSSPEC;
