I have a GUI which the idea is to scan a folder for executable files and output a script to silently install those software, in the order you want.

I would like to ask a few questions

1) Most important is I am using GUIScrollbars_Ex.au3 to have a vertical scroll bar, incase the items exceeds my GUI, I want to be able to scroll up and down, however if I delete an item past the end of the page, eg the last item, it makes the scroll bar appear at where the item was rebuilt.

2) My rudimentary GUI is flashing a lot, as I have to rebuild the buttons a lot, could someone advise or point on how to stop such heavy flashing and have a smoother experience ?

3) speed is slow.

NDog,

Let me take a look at how your script might be recast to prevent the problems you are seeing - it will keep me occupied on this grey and cold Sunday afternoon.

NDog,

Not too hard.

You need to use the other UDF in my Scrollbars UDF package - _GUIScrollBars_Size - as that is the one which deals with variable height scrollbars:
