Question: I'd like to prominently show a 'help' button when my meteor app is opened for the first time (on iOS). What's the best way to achieve this? That is, how can I easily confirm my meteor app is opened for the first time, after installing the app on iOS.

Answer: 
Use the `Random` class and limit the random numbers within an interval:

Java sample as original post was not marked with language, for C# - remove `final` and use `System.Random` to select value: 

```
private void button2_Click(object sender, EventArgs e)
{
    final String[] urls = {
      "http://google.com",
      "http://yahoo.com",
      "http://stackoverflow.com"
    };

    final int pick = (int)(Math.random() * urls.length);
    Process.Start(urls[pick]);
}  

```
Random number generator (should be a library for it in c#.

Add in a couple variables with your links, maybe store them in an array.

Then run that line you have with the array at the index that was randomly generated.
