Hi!
I have this HTA to compare two files, but i just want to improve it more and more. So my question is : How to make error handling for the end user when it fails or fogots to choose the file N°1 or File N°2 or both ?
i.e showing a msgbox to warn him that has missed to choose the file for example and exit the function or something else
Thank you in advance for your help !
