Younger brother small contact D3D10/11/12 half a year, now because of the need to send this post for help,

D3D9, I want to save out of the depth map and the depth of the known only D3DFMT_D16_LOCKABLE is lockable in the format, that for the other format what should I do to save depth surface for DDS format file?

Use the D3DXSaveSurfaceToFile? Always returns 0 xdeadbeef is how to return a responsibility?

Please help ~
