title: How to use DialogBoxParam?
body: <p>I have a pre-made template resource dialog, and I want to use <code>DialogBoxParam</code> to display it, but I can't find any good examples over the internet. The dialog is a simple login dialog, so can someone explain how to build my <code>lpDialogFunc</code> and what to put in <code>dwInitParam</code>?</p>
