Delphi - Memo Right Click Get Line Number

How do I get the line number of a memo when I right click on it?

A ListBox has .ItemAtPos but I've not been able to find a similar function

From stackoverflow
  • Check CaretPos property.

    Remy Lebeau - TeamB : That only works when WordWrap=False
  • In Delphi 2010, TRichEdit has an ActiveLineNo property. Not sure if it exists in Delphi 2009.

    The manual way to get the line number is to send the Memo an EM_LINEFROMCHAR message with the WParam value set to -1, ie:

    LineNo := SendMessage(Memo1.Handle, EM_LINEFROMCHAR, -1, 0);
    

    Or:

    LineNo := Memo1.Perform(EM_LINEFROMCHAR, -1, 0);
    
    Brad : manual way Works perfectly for what I need!
