OLE DB on Desktop

hello everybody,

I've installed SQL Compact Edition (with Visual Studio 2005) and i try to compile Northwindoledb for the DeskTop. The goal of this operation is to migrate a Pocket PC application (C++/OLE DB/SQL Mobile) to the desktop. If i can run properly Northwindoledb project i could start to migrate ...

I've the following error :

hr = pICmdText->Execute(NULL, IID_NULL, NULL, NULL, NULL);

GUID_NULL undefined

What can i do ?

Thanks in advance !I've found the following definition :

#define DEFINE_GUIDSTRUCT(g, n) struct __declspec(uuid(g)) n
#define DEFINE_GUIDNAMED(n) n

DEFINE_GUIDSTRUCT("00000000-0000-0000-0000-000000000000", GUID_NULL);
#define GUID_NULL DEFINE_GUIDNAMED(GUID_NULL)
I will see if it works ...
