SPBM_QUERYVALUE Field - usBufSize

usBufSize (USHORT)

Buffer size.

If usBufSize is too small to return all of the text, the spin button returns as much of the text as it can.

• The spin button assumes that param1 is the address of a long variable. If the data in the spin button is spinning between an upper and lower limit, the current value is passed back in the variable.

  If the data in the spin button is in an array, the index of the current array value (or last valid value) is passed back in the variable.

  Other

  The spin button assumes that param1 is the address of a string. The information passed back in the string is dependent upon the flags in the usValue parameter.
