I'm having trouble copying from a pointer to an array of vertices. Heres some code:

Unfortunatly, it only solved part of my problem. I have 2 VB''s, and only one is drawing.
Any ideas on what might cause the polygons not to show up from one VB and still show up on another? I don''t change any renderstates or anything, and the framerate does fall when I draw the second VB, but nothing shows up.
As far as I can tell, the data is correct. Any ideas?

There''s so many reasons for such odd behavior... :/
Do you have two identical VBs, or what?
Could be the vertex format change, or something...
I''ll post if something obvious comes to mind

I get a weird access violation if I allocate too much memory while dealing with a VB. Never could figure it out .
Anywho, I've got 2 VB's, and as far as I can tell, theres no reason why the second shows nothing, but who knows these days.
heres some code:
Render():
Load(): ( a little long, sorry.)
[EDIT] As far as I can tell, the load function is putting the correct values into the Verices2 array, but for some reason when rendering, nothing shows.
Like I said before, the framerate DOES drop when I render the second VB.

I suggest putting a load of "if(FAILED(...)) ReportError();" in your code to narrow down which lines causing the problem, then once you have the offending line you can put a "HRESULT err = bla()" and look up in the documentation what the possible values for "err" could be, e.g. in my program I have:
You could implement something similar:
if (FAILED(d3dDevice->DrawPrimitive( D3DPT_TRIANGLELIST, 0, 630))
ReportError();
Then something simliar to above to narrow the exact problem.
Dave.
HRESULT err = m_pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, g_hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &m_Params, &m_pDevice); switch(err){ case D3D_OK: break; case D3DERR_INVALIDCALL: reportError("D3DERR_INVALIDCALL"); break; case D3DERR_NOTAVAILABLE: reportError("D3DERR_NOTAVAILABLE"); break; case D3DERR_OUTOFVIDEOMEMORY: reportError("D3DERR_OUTOFVIDEOMEMORY"); break; default: reportError("Unknown Error"); }You could implement something similar:
if (FAILED(d3dDevice->DrawPrimitive( D3DPT_TRIANGLELIST, 0, 630))
ReportError();
Then something simliar to above to narrow the exact problem.
