Parameters

• ich

If this parameter is -1, the message returns the number of unselected characters on lines containing selected characters. For example, if the selection extended from the fourth character of one line through the eighth character from the end of the next line, the return value would be 10 to include three characters on the first line and seven on the next.

• lParam
  Not used; set to 0.

Return Value
