Set a value of the field. Pushbutton fields and signature fields don't have a value, list boxes can have multiple values selected if f_MultiSelect is set. Hard line breaks for multiline text fields(ie, text fields with flag f_MultiLine set) are encoded as "\r", "\n", or "\r\n".The behavior for values containing line breaks is undefined if the f_MultiLine flag is not set. After calling this function, getValueIndex() will return -1.

	int index,
