Reading Typelib

[TouEnMasm]

I have a problem reading a Typelib inside an exe
All is good until I call GetIDsOfNames

;Load the type library from our EXE's resources
invoke GetModuleFileNameW,g_hModule,addr WfileName,MAX_PATH
;LoadRegTypeLib
invoke LoadTypeLibEx,addr WfileName,REGKIND_NONE,addr ppvITypeLib
;invoke RegisterTypeLib,ppvITypeLib,addr WfileName, NULL
ITypeLib GetTypeInfoOfGuid,addr IID_IFrscript,addr ITypeInfo
ITypeInfo GetIDsOfNames,addr szfunct,1,addr rgDispID    ;access violation

The help file on the function is very confused.
I put a sample here.

.data
dispid          dd 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
rgszNames  dd 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
pcNames dd 0
.code
ITypeInfo GetNames,1,addr rgszNames,sizeof rgszNames,addr pcNames      
ITypeInfo GetIDsOfNames,addr rgszNames,pcNames,addr dispid
lea ebx,rgszNames
@@:
.if dword ptr [ebx] != 0

   invoke SysFreeString,ecx
   mov dword ptr [ebx],0

.endif
