<p>What is the best way to design an interface so that very long drop down values that get trucated due to size limits do not create a very bad user experience. My question is for web applications.</p>
<p>Could you please send your suggestions.</p>

<p>As most of you probably noticed, when uninstalling an MSI package Windows will ask for the original <code>.msi</code> file. Why is that?</p>

<p>Is there any way in Python to determine what exceptions a (built-in) function might raise? For example, the documentation (<a href="http://docs.python.org/lib/built-in-funcs.html" rel="nofollow noreferrer">http://docs.python.org/lib/built-in-funcs.html</a>) for the built-in int(s) says nothing about the fact that it... | <p>The only way to tell what exceptions something can raise is by looking at the documentation.
