IMAPIFormContainer::CalcFormPropSet

The IMAPIFormContainer::CalcFormPropSet method returns an array of the properties used by all forms installed within a form container.

Quick Info

See IMAPIFormContainer : IUnknown.

HRESULT CalcFormPropSet(
  ULONG ulFlags,                       
  LPMAPIFORMPROPARRAY FAR * ppResults  
);

Parameters

ulFlags

[in] Bitmask of flags that controls how the property array in the ppResults parameter is returned. The following flags can be set:

FORMPROPSET_INTERSECTION: The returned array contains the intersection of the forms' properties.
FORMPROPSET_UNION: The returned array contains the union of the forms' properties.
MAPI_UNICODE: The strings returned in the array are in Unicode format. If the MAPI_UNICODE flag is not set, the strings are in ANSI format.

ppResults

[out] Pointer to a pointer to the returned SMAPIFormPropArray structure. This structure contains all properties used by the installed forms.

Return Values

S_OK: The call succeeded and has returned the expected value or values.
MAPI_E_BAD_CHARWIDTH: Either the MAPI_UNICODE flag was set and the implementation does not support Unicode, or MAPI_UNICODE was not set and the implementation only supports Unicode.

Remarks

Client applications call the IMAPIFormContainer::CalcFormPropSet method to obtain an array of properties used by all forms installed within a form container. CalcFormPropSet works like the IMAPIFormMgr::CalcFormPropSet method, except that it operates on every form registered in a particular container.

Notes to Implementers

Form library providers that do not support Unicode strings should return MAPI_E_BAD_CHARWIDTH if MAPI_UNICODE is passed.

Notes to Callers

CalcFormPropSet either takes an intersection or a union of the forms' property sets, depending on the flag set in the ulFlags parameter, and it returns an SMAPIFormPropArray structure containing the resulting group of properties.

If a client passes the MAPI_UNICODE flag in ulFlags, all strings returned are Unicode.
