Re: [Flashcoders] Caret position coords
Easy... get the x,y in characters of the memo function getCharacterPosition( aMemo: TMemo ): TPoint begin Result.X := LongRec( SendMessage( aMemo.Handle, EM_GETSEL, 0, 0 ) ).Hi; Result.Y := SendMessage( aMemo.Handle, EM_LINEFROMCHAR, Result.X, 0 ); Result.X := Result.X - SendMessage(aMemo.Handle, EM_LINEINDEX, -1, 0); return Result; end; and get the x,y in pixels of the memo function getCharPositionInPixels( aMemo: TMemo ): TPoint var result: TPoint; begin result := aMemo.Perform( EM_POSFROMCHAR, WPARAM(@result), aMemo.SelStart); return result; end Not sure if the code is error free, though but are these api messages ;-) Yours, Weyert de Boer ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Caret position coords
To answer the original question - there is no direct way to do this, although you can use the text-extent to get the x offset of the caret fairly easily in a single line textfield.
