<p>I want to prevent the user from maximizing the Windows Form to full screen so I have disabled the Maximize button. However, I want to be able to have the user 'restore' the Form. When they click the Restore button I want it to show a different, smaller, minified, form, which will show them a maximize button which wi... | <p>I looked at a similar problem to this at work and the only solutions I could find involved setting undocumented window styles, which I was not inclined to do. </p>

It leaves the Minimise, Maximise and Restore buttons as they are, and has a separate button on the bottom right for "Switch to Compact Mode".

<p>In my java code, how can i get the current running application port?</p>

<p>I'm doing some shennanigans with jQuery to put little plus/minus icons next to my expanders. Its similar to the windows file trees, or firebugs code expanders.</p>

<p>This is what you want. It will select all of the nodes that are children of your list. In your case, all of your images are nested inside of the list element, so this will filter out only what you want.</p>
