I'm not sure I'm following you, either, but just in case this is what you want ...
When you align components you must be aware that the intrinsic border of the control plays a role too. In your case, the (widgetset dependent) border of the memo is a simple line, while the border of the button is a bit more complex (and fatter). What this means is that, aligned on top, the caption of the button will naturally be a little lower than the first line of the memo.
There is little you can do about this, since it's all system-dependent, i.e. it depends on the operating sytem, the widget-set, the desktop manager, the desktop theme, ... most of which is outside and independent of your program.
Regarding this:
Designer holding my movement when I try to move near by memo.
Other way user have align by first component.
May it be that you have "snap to grid" selected for control-positioning? Or maybe the button and/or memo have some
BorderSpacing set?
