I also tried this method and had the same result
as Jan ie:
======================
Symbol Undefined _IID_IDirectDraw7
Lines Processed: 130061  Errors: 1  Warnings: 1

=======================
Has anyone found a way around this problem?

Has anyone solved this problem?

I don't know what else you have tried, but a relatively simple, albeit hacky, way around this is to define the symbol internally.

const IID IID_IDirectDraw7 = { ... }

The value of IID_IDirectDraw7 will *never* change, so this should be fine.

However, you may want to insulate your code from a multiply defined symbol, if IID_IDirectDraw7 becomes linked in the future. A way to get around this is

// in global header
#define    IID_IDirectDraw7    IID_IDirectDraw7_internal


// in implementationfile.cpp
const IID IID_IDirectDraw7_internal = { ... };

That way even if/when you link to IID_IDirectDraw7 it'll all compile and link and work no problem.

Naturally it's a little unattractive, since it's a #define, but because of the immutability of IID values it is safe.

I've faced this problem couple months ago (mainly with DirectShow GUIDs), and found the cause and solution.

Cause: VC uses 'struct __declspec(uuid("..."))' constructions hidden via
MIDL_INTERFACE macro

Solution: I wrote special parser which went through all headers and extracted all GUIDs into separate sources, then compiled them and added to library.

I doubt if this lib becomes copyrighted, so I don't publish it here, but you are free to contact me directly and I will send it to you (in zip it is 48 Kb).

Yeah, create a file with the necessary IID's in there. Such as attached for
example...
Good luck!

I found an even simpler way from the Microsoft
website, just add the following line before including
ddraw.h like this:

#define INITGUID
#include "ddraw.h"

This fixes  all of the IID's

Thanks to all  for your suggestions.

Phill.

Cool!
This might add quite a bit of 'size' to your code though...

It does. That's the reason I often eschew it in favour of the "#define _" technique, especially when creating small COM DLLs

Ok , I see what you mean . Nic sent me a file
that has fixed the problem any way. Im just glad to
get rid of the headache and learn something new from
this. Im just another new Imigrant from Java.

Thanks
BTW, Jan your website has your old Email
address on it , I see you have a new one.
.cc -> .us
