SPropTagArray

The SPropTagArray structure contains an array of property tags.

Quick Info

typedef struct _SPropTagArray 
{ 
     ULONG      cValues; 
     ULONG      aulPropTag[MAPI_DIM]; 
} SPropTagArray, FAR *LPSPropTagArray; 
 

Members

cValues

Count of property tags in the array indicated by the aulPropTag member.

aulPropTag

Array of property tags.

Remarks

A property tag is a 32-bit unsigned integer made up of two parts:

• An identifier in the high-order 16 bits.
• A type in the low-order 16 bits.

The identifier is a numeric value within a particular range. MAPI defines ranges for identifiers to describe what the property is used for and who is responsible for maintaining it. MAPI defines constraints for each of the property tags that it supports in the MAPITAGS.H header file.

The type indicates the format for the property's value. MAPI defines constants for each of the property types that it supports in the MAPIDEFS.H header file.
