In the below code I need to reference the guid IID_ID2D1Factory. I'm using the coinvoke macro method. The second argument wants a REFIID type? I don't have a clue how to do that. Any help? Thx.   



invoke   D2D1CreateFactory,D2D1_DEBUG_LEVEL_NONE,REFIID(?),D2D1_FACTORY_TYPE_SINGLE_THREADED,addr   g_pD2D1Factory

;//+-----------------------------------------------------------------------------
;//
;//  Interface:
;//      ID2D1Factory
;//
;//  Synopsis:
;//      The root factory interface for all of D2D's objects.
;//
;//------------------------------------------------------------------------------
;06152247-6f50-465a-9245-118bfd3b6007"); Interface IID's

Try this macro:

GUID_ADDR MACRO guid_text:REQ
   LOCAL guid_data
   .data
    guid_data GUID guid_text
   .code
   EXITM <addr (guid_data)>
ENDM
IID_ID2D1Factory textequ <{006152247h,06f50h,0465ah,{092h,045h,011h,08bh,0fdh,03bh,060h,007h}}>

invoke   D2D1CreateFactory,D2D1_DEBUG_LEVEL_NONE,GUID_ADDR(IID_ID2D1Factory),D2D1_FACTORY_TYPE_SINGLE_THREADED,addr   g_pD2D1Factory
