Syntax

EM_LINELENGTH

    lParam = 0;

Parameters

• ich
  Specifies the character index of a character in the line whose length is to be retrieved when EM_LINELENGTH is sent to a multiline edit control. 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

The return value is the length, in characters, of the line specified by the ich parameter when an EM_LINELENGTH message is sent to a multiline edit control. The return value is the length, in characters, of the text in the edit control when an EM_LINELENGTH message is sent to a single-line edit control.

Remarks

Use the EM_LINEINDEX message to retrieve a character index for a specified line number within a multiline edit control.
