IMAPIFormMgr::ResolveMultipleMessageClasses

The IMAPIFormMgr::ResolveMultipleMessageClasses method resolves a group of message classes to their forms within a form container and returns an array of form information objects for those forms.

Quick Info

See IMAPIFormMgr : IUnknown.

HRESULT ResolveMultipleMessageClasses(
  LPSMESSAGECLASSARRAY pMsgClasses,          
  ULONG ulFlags,                             
  LPMAPIFOLDER pFolderFocus,                 
  LPSMAPIFORMINFOARRAY FAR * ppfrminfoarray  
);

Parameters

pMsgClasses

[in] Pointer to an array containing the names of the message classes to resolve.

ulFlags

[in] Bitmask of flags that controls how the message classes are resolved. The following flag can be set:

MAPIFORM_EXACTMATCH: Only message class strings that are an exact match should be resolved.

pFolderFocus

[in] Pointer to the folder containing the form whose message class is being resolved. The pFolderFocus parameter can be NULL.

ppfrminfoarray

[out] Pointer to a pointer to an array of form information objects. If a form viewer passes NULL in the pMsgClasses parameter, the ppfrminfoarray parameter contains form information objects for all forms in the container.

Return Values

S_OK: The call succeeded and has returned the expected value or values.

Remarks

Form viewers call the IMAPIFormMgr::ResolveMultipleMessageClasses method to resolve a group of message classes to forms within a form container. The array of form information objects returned in ppfrminfoarray provides further access to each of the forms' properties.

Notes to Callers

To resolve a group of message classes to forms, a form viewer passes in an array of message class names to be resolved. To force the resolution to be exact — that is, to prevent resolution to a superclass of the message class when an exactly matching form server is not available — the MAPIFORM_EXACTMATCH flag can be passed in the ulFlags parameter.

Message class names are always ANSI strings, never Unicode.

If a message class cannot be resolved to a form, NULL is returned for that message class in the form information array. Therefore, even if the method returns S_OK, form viewers should not work on the assumption that all message classes have been successfully resolved. Instead, form viewers should check the values in the returned array.
