typedef struct _SPBCDATA {
ULONG cbSize; /* Size of control block. */
ULONG ulTextLimit; /* Entryfield text limit. */
LONG lLowerLimit; /* Spin lower limit (numeric only). */
LONG lUpperLimit; /* Spin upper limit (numeric only). */
ULONG idMasterSpb; /* ID of the servant's master spinbutton. */

typedef SPBCDATA * PSPBCDATA ;
The SPBCDATA structure is used in the ctldata parameter of WinCreateWindow.
