preferences

I have some questions about the registry. We have Preferences p = Preferences.userRoot(); If we execute p.nodeExists("/HKEY_CURRENT_USER/Software/Policies/Microsoft") it will return true. After it: p = p.node("/HKEY_CURRENT_USER/Software/Policies"); for(String s : p.childrenNames()){ System.out.println(">" + s); } We see that it has one child: "Windows". But p.nodeExists("/HKEY_CURRENT_USER/Software/Policies/Microsoft/Windows") returns false. Why? Thanks. UPDATE Ok. I have some mistakes. Let me try again: Why does p.nodeExists("/HKEY_CURRENT_USER/Software/Policies/Microsoft/Windows") return

I've developed a firefox extension which contains a small dialog defined by this XUL script: <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <prefwindow id="firenowPreferences" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" title="Fire.Now" ondialogaccept='onSave();' onload="checkFields();"> <script type="application/x-javascript">function onSave(){ alert('blablabla');}</script> <prefpane id="pane1"> <grid> <rows> <row align="center"><label control="username">Username</label><textbox id="username"/></row> <row align=

I have an Android Service. When a phone boots up, a broadcast receiver receives a notification and it schedules the service to run repeatedly at a gap of X minutes. Henceforth After every X minutes another broadcast receiver gets those notifications and kicks the service off, which does it's job and quits. So far so good. Now I want those X minutes to be configurable. I have a perf.xml similar to what is given at the link below. This XML captures all my preferences along with that of service timer. http://android-journey.blogspot.com/2010/01/for-almost-any-application-we-need-to.html Now when

I have been trying to use java.util.logging.logger to log stuff on to a file on sdcard. Now, I want the logger to use a logging configuration/properties file that I will provide on the sdcard. One way that I have been trying is:- I have been trying to use logmanager and java.util.prefs.preferences, but I get the BackingStoreException-->AccessPermission Exception perculating down to an error message that .java/.userprefs/path represented by str/prefs.xml was not found. private void setLoggingProperties(File logProperties) throws Exception { try { if(logProperties!=null && logProperties.isFile()

I am looking to figure out a way to sort people into classes by preference. For example, say there are 100 students that are each going to be assigned one of five classes: Science - 40 seats Math - 15 seats History - 15 seats Computers - 20 seats Writing - 10 seats Each student has three preferred classes that are ordered by preference. What is the best way to approach dividing up the students so that as many people get their first and second choice classes as possible, while at the same time making sure that no class has too many students for the room. I've thought about approaching it by the

This problem turned out to be much more tricky than it first appeared as it wasn't a problem on all but a few devices. When creating a custom Preference by making it a subclass of Preference and also use a custom layout defined in an XML file in res/layout and use that layout in onCreateView() in the custom Preference it seems you completely loose the layout information the Preference-s normally have. Nothing strange with that, but if you still want a title (together with the new stuff), how do you specify the size of that title if you want it to be the same size as for other preferences? I
