You specify the size of the initial window of your AIR application within an application descriptor file, like below:

<?xml version="1.0"?>
<application xmlns="http://ns.adobe.com/air/application/1.0">
    :
    :
    <initialWindow>
	<title>MyWindow</title>
        <content>main.swf</content>
        <width>800</width>
        <height>600</height>
    </initialWindow>
    :
</application>

So, while evaluating AIR as a potential wrapper for our latest project, our only major issue is that AIR doesn't give you the option of creating more than one icon in the Windows Start Menu. Our products tend to come with associated config applications or support documents, and historically we've always put links to them in the Start Menu.

So I started to look into how to create Windows shortcuts using AIR.

This should have been easy, but thanks to Microsoft's proprietary binary file format, it really wasn't.
