HrGetOneProp

Last modified: July 23, 2011

Applies to: Outlook

Retrieves the value of a single property from a property interface, that is, an interface derived from IMAPIProp.

Header file:

Mapiutil.h

Implemented by:

MAPI

Called by:

Client applications and service providers

HrGetOneProp(
  LPMAPIPROP pmp,
  ULONG ulPropTag,
  LPSPropValue FAR * ppprop
);

pmp

[in] Pointer to the IMAPIProp interface from which the property value is to be retrieved.

ulPropTag

[in] Property tag of the property to be retrieved.

ppprop

[out] Pointer to a pointer to the returned SPropValue structure defining the retrieved property value.

MAPI_E_NOT_FOUND

The requested property is not available from the specified interface.

Unlike the IMAPIProp::GetProps method, the HrGetOneProp function never returns any warning. Because it retrieves only one property, it simply either succeeds or fails. For retrieving multiple properties, GetProps is faster.

You can set or change a single property with the HrSetOneProp function.
