Access the current row/column of a TMemo

Answer:

The following code reads and writes the cursor's position as row and column; 
counting starts at 0.

1   procedure GetMemoRowCol(M: TMemo; var Row, Col: LongInt);
2   begin
3     Row := SendMessage(M.Handle, EM_LINEFROMCHAR, M.SelStart, 0);
4     Col := M.SelStart - SendMessage(M.Handle, EM_LINEINDEX, Row, 0);
5   end;
6   
7   procedure SetMemoRowCol(M: TMemo; Row, Col: Integer);
8   begin
9     M.SelStart := SendMessage(M.Handle, EM_LINEINDEX, Row, 0) + Col;
10  end;
