How to call a function and give it a string : <p>Okay, I want to call the function OpenApp() (located in a class called API.vb), but when calling it I want to pass a string to it like that:</p>

<pre><code>API.OpenApp("Settings")
</code></pre>

<p>That's good, but how can I detect that this string has been passed, like so the function knows there's a string?</p>
