stupid question ?

C/C++ is case sensitive. myVar is NOT the same as myvar. Change setcooperativelevel to SetCooperativeLevel, release to Release, queryinterface to QueryInterface, etc.

When I wrote setcooperativelevel, I wanted to say SetCooperativeLevel. In fact, I nearly copied the code of the tutorial into a win32 file.
And I still wonder why it doesn''t work since this error is not mentioned in the directdraw tutorial
please help

Can you post your exact code? It''s hard to tell what''s going wrong when you just describe it like that.

make sure you didn''t make a stupid mistake.. this is what it should look like in your code

somewhere:

LPDIRECTDRAW lpdd;

then when you try to set the coop level:

lpdd->SetCooperativeLevel(blah);

make sure you used ->
hmm
check spelling..
thats all i can think of.

lol
missing semicolons, open/close brackets, double/single quotation marks, ->/. , */&
then if everything else failed. then look at the errors that compiler gave you
(i got point by that ya know)

ok
First, thanks to all for your answers...
But unfortunately it didn''t work

So here is my code (not the entire code but enough I think) :

LPDIRECTDRAW lpDD;
LPDIRECTDRAW lpDD2;

int DirectDrawInit(HWND hwnd)

{
HRESULT ddrval;

ddrval = DirectDrawCreate( NULL, &lpDD, NULL );
if( ddrval != DD_OK ) { return(0); }


ddrval = lpDD->QueryInterface(IID_IDirectDraw2,(LPVOID *)&lpDD2);
if( ddrval != DD_OK ) { lpDD->release(); return(0); }

lpDD->release();

ddrval = lpDD2->SetCooperativeLevel( hwnd, DDSCL_EXCLUSIVE | DDSCL_FULLSCREEN );
if( ddrval != DD_OK ) { lpDD2->Release(); return(0); }


ddrval = lpDD2->SetDisplayMode( 640, 480, 8);
if( ddrval != DD_OK ) { lpDD2->Release(); return(0); }

return(1);
}

Now just think about this :
- I got 8 errors from visual c++ 5 :
error c2039 : SetCooperativeLevel is not a member of IDirectDraw
The same errors for Release, QueryInterface, SetDisplayMode,...
- I have specified #include
- I included ddraw.h into my project files
- In classview, I can see IDirectDraw, IDirectDraw2,...
In IDirectDraw, I can see SetCooperativeLevel and SetDisplayMode for example : BUT When I try to see the functions definitions, the compiler says : "Cannot find the definition for this function : classview cannot find the function definitions until they are saved at least once "
Hope you will be able to help me

You created lpdd then used lpdd2 that could cause problems.

Sole thing I could point out is the fact that maybe you haven''t the libraries loaded, or your directories are wrong or missing, or you simply haven''t the file on your disk. The code seems ok, nearly nice (sorry, I''m OGl fan, and I find DX quite messy But of course that''s not the point).
The problem is around the "cannot-see-def" error... If you cannot see the definition of your classes, then it''s probably because you did something wrong. Solving it would problem wipe out the error list.
I''d guess that IDirectDraw is declared but contains nothing or something similar (he finds it but cannot tell where, or just #define #ifdef #ifndef problems... That might happens)

Have you tried it with VC6? Have you set correctly your directories in your options? Maybe it''s just cause the files are misplaced.

Programming is: A. The art of debugging a blank sheet of paper (or an empty file). B. A pastime similar to banging one's head against a wall, but with fewer opportunities for reward. C. The most fun you can have with your clothes on (although clothes are not mandatory).

(( BTW, he created lpDD2 from lpDD with QueryInterface... ))

Oh yeah! When you put code, please use the source tags... It gives something like this:

LPDIRECTDRAW lpDD; LPDIRECTDRAW lpDD2; int DirectDrawInit(HWND hwnd) { HRESULT ddrval; ddrval = DirectDrawCreate( NULL, &lpDD, NULL ); if( ddrval != DD_OK ) { return(0); } ddrval = lpDD->QueryInterface(IID_IDirectDraw2, (LPVOID *)&lpDD2); if( ddrval != DD_OK ) { lpDD->release(); return(0); } lpDD->release(); ddrval = lpDD2->SetCooperativeLevel( hwnd, DDSCL_EXCLUSIVE | DDSCL_FULLSCREEN ); if( ddrval != DD_OK ) { lpDD2->Release(); return(0); } ddrval = lpDD2->SetDisplayMode( 640, 480, 8); if( ddrval != DD_OK ) { lpDD2->Release(); return(0); } return(1); }

Oh and read a bit of Code Complete, please... Just a trick, because lines like "if( ddrval != DD_OK ) { lpDD2->Release(); return(0); }" are really hard to read. Don''t take it personnally, I just want to give you tips .

Ack I need to hurry up and get up to speed with directdraw.

i think this is your problem:

LPDIRECTDRAW2 lpDD2; //note: it''s LPDIRECTDRAW2

see if it works, that''s the only mistake i could find in your code
