ITypeInfo::GetNames

  • Article

This method retrieves the variable with the specified member identifier, or the name of the function and parameter names corresponding to the specified function identifier.

HRESULT GetNames( 
  MEMBERID memid, 
  BSTR FAR* rgBstrNames, 
  unsigned int cMaxNames, 
  unsigned int FAR* pcNames 
);

Parameters

  • memid
    [in] Identifier of the member whose name (or names) is to be returned.
  • rgBstrNames
    [out] Pointer to the caller-allocated array. On return, each of these lpcName elements is filled in to point to a BSTR that contains the name (or names) associated with the member.
  • cMaxNames
    [in] Length of the passed-in rgBstrNames array.
  • pcNames
    [out] On return, pointer to the number that represents the number of names in rgBstrNames array.

Return Values

The following table shows the return values for this function.

Value Description
S_OK Success.
E_OUTOFMEMORY Out of memory.
E_INVALIDARG One or more of the parameters is invalid.
TYPE_E_IOERROR The function could not read from the file.
TYPE_E_INVDATAREAD Invalid data.
TYPE_E_UNSUPFORMAT The type library has an older format.
TYPE_E_INVALIDSTATE The type library could not be opened.
TYPE_E_WRONGTYPEKIND Type mismatch.
TYPE_E_ELEMENTNOTFOUND The element was not found.

Remarks

The caller must release the returned BSTR array.

If the member identifier identifies a property that is implemented with property functions, the property name is returned.

For property get functions, the names of the function and its parameters are always returned.

For property put and put reference functions, the right side of the assignment is unnamed. If cMaxNamesis less than is required to return all of the names of the parameters of a function, then only the names of the first cMaxNames –1 parameters are returned. The names of the parameters are returned in the array in the same order that they appear elsewhere in the interface (for example, the same order in the parameter array associated with the FUNCDESC enumeration).

If the type description inherits from another type description, this function is recursive to the base type description, if necessary, to find the item with the requested member identifier.

Requirements

OS Versions: Windows CE 2.0 and later.
Header: Oaidl.h, Oaidl.idl.
Link Library: Oleaut32.lib, Uuid.lib.
