Displaying a long string in a spinner without cutting

In my current app, if the string is too long and doesn't fit into screen it gets cut. How to display rolling text for long strings in a spinner(i have seen that in some apps)? A Spinner extends AdapterView (like ListView does) which is backed by an Adapter class.So much like you can customise each row in a ListView, you should be able to do the same for your Spinner by overriding a method like Adapter.getView().There you could return a simple TextView with the ellipsize property. [XXX]If you are using a textview look at the ellipsize property with the marquee option. ...

To Fortify, what constitutes validating an integer?

I'm using Fortify static code analyzer with a C#/.NET project. I'm taking an integer parameter, a year, from user input and starting a process with that: int y = int.Parse(Year.SelectedValue); //Year is a DropDownList if (y >= 2017 && y <= DateTime.Today.Year) Process.Start(new ProcessStartInfo(Server.MapPath("~/bin/SomeProgram.exe"), "/x:" + y.ToString()));Fortify doesn't like that, throws a "Command Injection" issue: Data enters the application from an untrusted source.

apt-get update in a dockerfile destroys app consistency?

In the dockerfiles I have seen, and the in the best practices for writing a docker file: https://docs.docker.com/engine/reference/builder/#copy, when apt-get is used to install some packages, apt-get update is always run first. I have a concern on this because the app we build in the corresponding docker container would depend on these installed packages, if there is some inconsistency in the newest version of the installed packages, the software we build will not work right any more. Why we do not specify a version of the packages, but use apt-get update instead? From t...

Difference between const auto & and auto & if object of reference is const

// case 1const int i = 42;const auto &k = i;// case 2const int i = 42;auto &k = i;Do we need the const keyword before auto in this scenario? After all, a reference (k) to an auto-deduced type will include the top level const of the object (const int i). So I believe k will be a reference to an integer that is constant (const int &k) in both cases.If that is true, does that mean that const auto &k = i; in case 1 is replaced by the compiler as just const int &k = i; (auto being replaced with int)? Whereas in case 2, auto is replaced with const int? auto...
