I can't seem to copy a surface to backbuffer by any way .. it always return an InvalidCall ...

Here's what i've done :

//640,480

GRAFX->DEVICE()->CreateRenderTarget(m_Width, m_Height, D3DFMT_X8R8G8B8, D3DMULTISAMPLE_NONE, 0, false, &m_Surface, NULL)


LPDIRECT3DSURFACE9 s;

GRAFX->DEVICE()->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &s);

GRAFX->DEVICE()->UpdateSurface(m_Surface, NULL, s, NULL);


//

It doesn't seem to work with regular surfaces either, nor with GetRenderTargetData ...

Help please !! :(

Not sure this will help but what works for me is to use:

g_pd3dDevice->CreateOffscreenPlainSurface(Width, Height, D3DFMT_X8R8G8B8, D3DPOOL_SYSTEMMEM, &g_BackgroundSurface, NULL);

Then:

g_pd3dDevice->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &g_BackBuffer);
g_pd3dDevice->UpdateSurface(g_BackgroundSurface, NULL, g_BackBuffer, NULL);

what's the difference between a rendertarget surface and an offscreenplainsurface ?
