Answer 1

Your dialog must communicate the results of your work in some way.
Usually, console utilities use either a return code (the result of return in main), or, if there is a lot of information returned, text output to the console. In the batch file, the output to the console and the return code can be processed as you need.
You can do the same in dialog, regardless of the fact that it is not a console application.

I could do it on shell

In fact, everything is the same in nix - the called program must somehow inform the caller of the results of its work. The standard options are the same in Windows and in nix.
