Exception handling in Mathematica

Questions

What is the cleanest way to handle exceptions in Mathematica. For example:

(* import the Zoom report *)

ecicc = Import[SystemDialogInput["FileOpen"]];

(* convert the Zoom dates into DateObjects *)

I want to let the user select a file, and then process the contents. However, if no file is selected, e.g. Cancel is clicked, I need to not execute the code. Obviously, I could wrap all the code in an If statement, but that seems very clumsy. How do Mathematica programmers handle this situation in a functional style?

Hey Andrew,
I tried here.. and.. you could use the following code

test = Quiet[Import[SystemDialogInput["FileOpen"]]];
If[FailureQ@test, "Please, select a file to continue", test]
Out[2] = "Please, select a file to continue"

Ah, that’s very helpful, thank you. I didn’t know about Quiet[]

Cheers
