The D3DPICKRECORD structure returns information about picked primitives in an execute buffer for the IDirect3DDevice::GetPickRecords method.
typedef struct _D3DPICKRECORD { 
    BYTE     bOpcode; 
    BYTE     bPad; 
    DWORD    dwOffset; 
    D3DVALUE dvZ; 
} D3DPICKRECORD, *LPD3DPICKRECORD; 
 The x- and y-coordinates of the picked primitive are specified in the call to the IDirect3DDevice::Pick method that created the pick records.
