Alright, time to dive into something I've never delt with in my year+ of using DirectX 8 - surfaces. I really cant find much about surfaces for DirectX 8, either. What I need to do it create a surface, use the Direct3DDevice to draw to it, then display it to a picturebox (possibly by getting the HDC and using BitBlt?).

Anyone care to help me out? I'm totally lost on all of this. :P

Maybe initialize the d3ddevice on the picturebox´s hwnd?

I was actually thinking of doing that, problem is I have about 13 pictureboxes I want to draw to. Do you think this would have a drastic impact on speed or RAM? I dont see the speed being affected much (seeing that it wont be called every frame, only one is the game screen, rest is updated randomly) but it may take up a bit of RAM...

I may just do that, since it seems to be like it'd give me the most flexability and killpower.

Well its either you waste ram or you waste a lot of cpu power(bitblt is slow as heck) and since today's computers usualy have 512mb+ ram(usualy 1gb) wasting a bit of ram shouldn't be a problem. Back in the old days it was(remember quickbasic?).

Present call:

Quote:
HRESULT Present(
CONST RECT * pSourceRect,
CONST RECT * pDestRect,
HWND hDestWindowOverride,
CONST RGNDATA * pDirtyRegion
);


Quote:
hDestWindowOverride
[in] Pointer to a destination window whose client area is taken as the target for this presentation. If this value is NULL, then the hWndDeviceWindow member of D3DPRESENT_PARAMETERS is taken.

Thank you Almar! That makes everything real FREAKING easy! 8)

The pSrcRect and pDestRect were easy to figure out, too. Just have to set a normal ol' rect. GOD I love DirectX 8 now!! Weeee!!!! :spin :spin :spin :spin :spin :spin

You're welcome :). It might be an idea to keep all your problems organized in one topic, makes it easier to know what you're talking about - I think. :)

Well they are all seperate problems that come up at seperate times - just happen to all involve transfering a DirectX 7 program to DirectX 8. :P
