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 rnd = new Random();
int website = rnd.Next(0, numOfWebsites);
switch(website)
{
    case 0:
    {
        Process.Start("http://google.com");
        break;
    }
    case 1:
    {
        Process.Start("http://yahoo.com");
        break;
    }
}

```

You can use a switch case statement for readability with a random number generator. I apologize if i made any errors as i don't use C# much. A if else statement would also work for a situation like this.
