Hi everyone, I am trying to lock a frontbuffer, but can''t seem to suceed. I can get the back buffer, because in Direct3D8Device present parameters there are lockable traits I can set to the backbuffer. Is there also locakable traits to the frontbuffer? Do anyone have any code that works with locking FrontBuffer? Thanks.

I don''t think you can. You can get a copy of it using IDirect3DDevice8::GetFrontBuffer().

Anyway, assuming you can lock the front-buffer, it''s a bad thing. It''s going to stall the pipeline. Why do you want to do it?

I actually want to do this because there is a couple pixel modification things I want to do and then show then on another Picture box. I know it can be done, but don''t know what flags to set in the present parameters or the picture box itself. would you have any ideas?

Why not lock the back buffer?
