Hello Everyone, I am new to Auioit, post installation of auoit I went and saw several constant files containing hexcode for various global constant variables.I was curious to know the significance of these files and content in it. How are these being used? Another question was how exactly autoit works, how does it identify(internally) an control on desktop based applications. I tried to google for it but did not find answer. It would be great if anyone can give a pointer to these queries. Thanks in Advance. Sachin
