EM_LINEFROMCHAR message
Gets the index of the line that contains the specified character index in a multiline edit control. A character index is the zero-based index of the character from the beginning of the edit control. You can send this message to either an edit control or a rich edit control.
Parameters

The character index of the character contained in the line whose number is to be retrieved.

lParam

This parameter is not used.
Return value
The return value is the zero-based line number of the line containing the character index specified by wParam.
Remarks
