AUIT: TAutoItX3;

AUIT := TAutoItX3.Create(nil);

; seconds parameter cannot be empty otherwise get error
; so it needs always text
; is there a way to skip the second parameter for use in delphi

As far as I know all paramaters need to be passed to functions, they are not optional.

It's actually a pair of errors mixed together.

1. AutoItX apparently doesn't recognize null pointers.

2. Delphi is converting your empty string to a null instead of passing an empty string.
