I how about this one?
My Design
sorry if its only an image. this is just an idea but im still hoping that it can help you.
i currently dont have autoit or visual studio in this laptop so i made one using MSpaint. XD
I dont know if you can make this in Autoit but im sure this is possible in Visual basic.
*as you can see, i change the name to key to the user can change it to their convenience.
*the textbox control and the updown control will be hidden. it will only show if the user click the Edit buton, Copy Button, or double click the row in listview control
*the Top, Left, width, height of textbox control and the updown control will be the same with the Top, Left, width, height of the list view row.
ill try to think some other design aside from this one if i got some time,. i hope this one help you give some other idea that is outside the box. GL
