EM_LINEINDEX

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.
