EM_LINEINDEX Overview  Group

An application sends an EM_LINEINDEX message to retrieve the character index of a line in a multiline edit control. The character index is the number of characters from the beginning of the edit control to the specified line.

EM_LINEINDEX 

wParam = (WPARAM) line; // line number 

lParam = 0;             // not used; must be zero 

 

Parameters

line
Value of wParam. Specifies the zero-based line number. A value of -1 specifies the current line number (the line that contains the caret).

Return Values

The return value is the character index of the line specified in the line parameter, or it is -1 if the specified line number is greater than the number of lines in the edit control.
