DirectX7

Try the function
DirectDrawCreateEx
Look it up for syntax!
I had this problem a long time ago when converting my code to the lastest interfaces!

Here ya go
DirectDrawCreateEx(pDriverGUID,(VOID**&g_pDD,IID_IDirectDraw7,NULL );

Thnx...
But it seems that the function does not take 3 parameters, and i dont have Dx7 helpfiles....

Trying to d/l it from Microsfot..but that seems impossible

//Metus

there're probably other ways, but these two should work:
the first one i've not used, but it's on a DX7 book i have

LPDIRECTDRAW7 lpdd = NULL;
DirectDrawCreateEx(NULL,(LPVOID *)&lpdd,IID_IDirectDraw7,NULL);

 

or this:

LPDIRECTDRAW lpdd = NULL;
LPDIRECTDRAW7 lpdd7 = NULL;
DirectDrawCreate(NULL,&lpdd,NULL);
lpdd->QueryInterface(IID_IDirectDraw7,(LPVOID *)&lpdd7);
 

in that last one you create a DD object, and use to to query for a newer version, afterwards you can destroy it, as you have no use for the original anymore.

hopefully this is helpful

Well, the old errormessage disapperad, but a new one came up;
error LNK2001: unresolved external symbol _IID_IDirectDraw7

What does this mean?
I do have DX7 Libs and Headers, and #included

I''m going nuts...

//Metus

that''s a very simple problem that drove me insane for about a week..
did you include (not #include, but add to the project) dxguid.lib?

Wow...it worked thanks a lot
ONe more thing:
Do you know if i can set some libraries (Like DDraw.lib, DSound.lib, Winmm.lib an further on) as "standard" libraries so i wont need to include them again if i''ll create another project, and stop the riks of forgetting them?

Thanks again
//Metus

it would make alot of sense for MSVC++ to give you that kind of option, but if there is one, i don''t know about it..

yes, you can have "default" libraries (in a way). set the LINK environment variable to point to any libraries you want.

i personally haven''t used this, since it would link ALL subsequent projects to these libraries, but it sounds like it should work.

some people think i'm crazy, some people know it
