IAMTimelineObj::GetSubObjectGUIDB

The GetSubObjectGUIDB method retrieves the GUID of the subobject associated with this timeline object. This method is equivalent to IAMTimelineObj::GetSubObjectGUID, but receives a BSTR value.

Syntax

  HRESULT GetSubObjectGUIDB(
    BSTR *pVal
);

Parameters

pVal

[out, retval] Pointer to a BSTR that receives a string representing the subobject GUID.

Return Value

Remarks

The method allocates memory for the string. The application must call SysFreeString to free the memory.
