I solved, in 64bit system, should not specify Pack=4 here: https://github.com/smourier/DirectN/blob/cc5b3918e0ca755219372203e7220c287e67931e/DirectN/DirectN/Generated/_D3DLOCKED_RECT.cs#L7

Hi,

Yes. The problem is DirectX9 support in DirectN is pretty much hardcoded for x86 (it's not only D3DLOCKED_RECT...)

If you use the source and not the .dll you can change that yourself, but I would like to modify the code to support both x86 and x64. I'll keep the issue open and will try to fix that in a near future...

Thanks :-)

This commit https://github.com/smourier/DirectN/commit/a15d399dc2311ce812038f517d5bca3aba2878ee should improve all that. Note it may change the way to call some DirectX9 interfaces.
