  • What add-in/workbench framework is the best .NET alternative to Eclipse RCP?

    - by Winston Fassett
    I'm looking for a plugin-based application framework that is comparable to the Eclipse Plugin Framework, which to my simple mind consists of: a core plugin management framework (Equinox / OSGI), which provides the ability to declare extension endpoints and then discover and load plugins that service those endpoints. (this is different than Dependency Injection, but admittedly the difference is subtle - configuration is highly de-centralized, there are versioning concerns, it might involve an online plugin repository, and most importantly to me, it should be easy for the user to add plugins without needing to know anything about the underlying architecture / config files) many layers of plugins that provide a basic workbench shell with concurrency support, commands, preference sheets, menus, toolbars, key bindings, etc. That is just scratching the surface of the RCP, which itself is meant to serve as the foundation of your application, which you build by writing / assembling even more plugins. Here's what I've gleaned from the internet in the past couple of days... As far as I can tell, there is nothing in the .NET world that remotely approaches the robustness and maturity of the Eclipse RCP for Java but there are several contenders that do either #1 or #2 pretty well. (I should also mention that I have not made a final decision on WinForms vs WPF, so I'm also trying to understand the level of UI coupling in any candidate framework. I'm also wondering about platform coupling and source code licensing) I must say that the open-source stuff is generally less-documented but easier to understand, while the MS stuff typically has more documentation but is less accessible, so that with many of the MS technologies, I'm left wondering what they actually do, in a practical sense. These are the libraries I have found: SharpDevelop The first thing I looked at was SharpDevelop, which does both #1 and also #2 in a basic way (no insult to SharpDevelop, which is admirable - I just mean more basic than Eclipse RCP). However, SharpDevelop is an application more than a framework, and there are basic assumptions and limitations there (i.e. being somewhat coupled to WinForms). Still, there are some articles on CodeProject explaining how to use it as the foundation for an application. System.Addins It appears that System.Addins is meant to provide a robust add-in loading framework, with some sophisticated options for loading assemblies with varying levels of trusts and even running the out of process. It appears to be primarily code-based, and pretty code-heavy, with lots of assemblies that serve to insulate against versioning issues., using Guidance Automation to generate a good deal of code. So far I haven't found many System.AddIns articles that illustrate how it could be used to build something like an Eclipse RCP, and many people seem to be wringing their hands about its complexity. Mono.Addins It appears that Mono.Addins was influenced by System.Addins, SharpDevelop, and MonoDevelop. It seems to provide the basics from System.Addins, with less sophisticated options for plugin loading, but more simplicity, with attribute-based registration, XML manifests, and the infrastructure for online plugin repositories. It has a pretty good FAQ and documentation, as well as a fairly robust set of examples that really help paint a picture of how to develop an architecture like that of SharpDevelop or Eclipse. The examples use GTK for UI, but the framework itself is not coupled to GTK. So it appears to do #1 (add-in loading) pretty well and points the way to #2 (workbench framework). It appears that Mono.Addins was derived from MonoDevelop, but I haven't actually looked at whether MonoDevelop provides a good core workbench framework. Managed Extensibility Framework This is what everyone's talking about at the moment, and it's slowly getting clearer what it does, but I'm still pretty fuzzy, even after reading several posts on SO. The official word is that it "can live side-by-side" with System.Addins. However, it doesn't reference it and it appears to reproduce some of its functionality. It seems to me, then, that it is a simpler, more accessible alternative to System.Addins. It appears to be more like Mono.Addins in that it provides attribute-based wiring. It provides "catalogs" that can be attribute-based or directory-based. It does not seem to provide any XML or manifest-based wiring. So far I haven't found much documentation and the examples seem to be kind of "magical" and more reminiscent of attribute-based DI, despite the clarifications that MEF is not a DI container. Its license just got opened up, but it does reference WindowsBase -- not sure if that means it's coupled to Windows. Acropolis I'm not sure what this is. Is it MEF, or something that is still coming? Composite Application Blocks There are WPF and Winforms Composite Application blocks that seem to provide much more of a workbench framework. I have very little experience with these but they appear to rely on Guidance Automation quite a bit are obviously coupled with the UI layers. There are a few examples of combining MEF with these application blocks. I've done the best I could to answer my own question here, but I'm really only scratching the surface, and I don't have experience with any of these frameworks. Hopefully some of you can add more detail about the frameworks you have experience with. It would be great if we could end up with some sort of comparison matrix.

  • Problem with From field in contact form and mail() function

    - by Matthew
    I've got a contact form with 3 fields and a textarea... I use jQuery to validate it and then php to send emails. This contact form works fine but, when I receive an email, From field isn't correct. I'd like to want that From field shows text typed in the Name field of the contact form. Now I get a From field like this: <[email protected]> For example, if an user types "Matthew" in the name field, I'd like to want that this word "Matthew" appears in the From field. This is my code (XHTML, jQuery, PHP): <div id="contact"> <h3 id="formHeader">Send Us a Message!</h3> <form id="contactForm" method="post" action=""> <div id="risposta"></div> <!-- End Risposta Div --> <span>Name:</span> <input type="text" id="formName" value="" /><br /> <span>E-mail:</span> <input type="text" id="formEmail" value="" /><br /> <span>Subject:</span> <input type="text" id="formSubject" value="" /><br /> <span>Message:</span> <textarea id="formMessage" rows="9" cols="20"></textarea><br /> <input type="submit" id="formSend" value="Send" /> </form> </div> <script type="text/javascript"> $(document).ready(function(){ $("#formSend").click(function(){ var valid = ''; var nome = $("#formName").val(); var mail = $("#formEmail").val(); var oggetto = $("#formSubject").val(); var messaggio = $("#formMessage").val(); if (nome.length<1) { valid += '<span>Name field empty.</span><br />'; } if (!mail.match(/^([a-z0-9._-]+@[a-z0-9._-]+\.[a-z]{2,4}$)/i)) { valid += '<span>Email not valid or empty field.</span><br />'; } if (oggetto.length<1) { valid += '<span>Subject field empty.</span><br />'; } if (valid!='') { $("#risposta").fadeIn("slow"); $("#risposta").html("<span><b>Error:</b></span><br />"+valid); $("#risposta").css("background-color","#ffc0c0"); } else { var datastr ='nome=' + nome + '&mail=' + mail + '&oggetto=' + oggetto + '&messaggio=' + encodeURIComponent(messaggio); $("#risposta").css("display", "block"); $("#risposta").css("background-color","#FFFFA0"); $("#risposta").html("<span>Sending message...</span>"); $("#risposta").fadeIn("slow"); setTimeout("send('"+datastr+"')",2000); } return false; }); }); function send(datastr){ $.ajax({ type: "POST", url: "contactForm.php", data: datastr, cache: false, success: function(html) { $("#risposta").fadeIn("slow"); $("#risposta").html('<span>Message successfully sent.</span>'); $("#risposta").css("background-color","#e1ffc0"); setTimeout('$("#risposta").fadeOut("slow")',2000); } }); } </script> <?php $mail = $_POST['mail']; $nome = $_POST['nome']; $oggetto = $_POST['oggetto']; $text = $_POST['messaggio']; $ip = $_SERVER['REMOTE_ADDR']; $to = "[email protected]"; $message = $text."<br /><br />IP: ".$ip."<br />"; $headers = "From: $nome \n"; $headers .= "Reply-To: $mail \n"; $headers .= "MIME-Version: 1.0 \n"; $headers .= "Content-Type: text/html; charset=UTF-8 \n"; mail($to, $oggetto, $message, $headers); ?>

  • Anchor bug on IE9, anchor hitbox overlapped

    - by user1456399
    The menu below works just fine in Firefox and Chrome, but in IE9, but hitbox for the "HOME" anchor is being covered partially by the list item behind it except for the actual test, and a single horizontal pixel line at the top and bottom of the button. Can anyone see what I'm missing? Code to follow: index.html <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" > <title>Navigation</title> <style> .menu-container { width:960px; height:45px; margin:0 auto; position:relative; z-index:2; background-color: #3d3d3d; margin-bottom: 20px; } .menu-navigation { font-family:Arial, Helvetica, sans-serif; font-size:13px; list-style:none; padding:0; margin:0; text-align: right; font-size: 0; /* Removes whitespace between <li> */ } .menu-navigation > li { display:inline; margin:0; border-left:solid 1px #242424; background-color:transparent; font-size: 12px; padding: 15px 0 15px 0; } .menu-navigation > li:hover, .menu-navigation > li.current-menu-item { background-color:#202020; } .menu-navigation > li.active, .menu-navigation > li.active:hover { background-color:#131313; } .menu-navigation > li a { text-decoration:none; color:#bbbbbb; } .menu-navigation > li a:hover { color:#efefef; } .menu-navigation > li span a { color:#ffffff; } .menu-navigation > li a:focus { outline:none; } .menu-navigation > li.menu-item-parent > span, .menu-navigation > li > span > a { text-transform:uppercase; outline:0; text-decoration:none; color:#ffffff; text-shadow:1px 1px 1px #000000; line-height: 45px; display: inline-block; height: 45px; padding: 0 20px 0 20px; } .menu-navigation > li.menu-item-parent > span { background:url("../img/down.png") no-repeat right center; } .menu-navigation > li.menu-item-parent > span:hover, .menu-navigation > li > span > a:hover { cursor:pointer; } </style> </head> <body> <div class="menu-container"> <ul class="menu-navigation"> <li><span><a href="#">This is a link</a></span></li> <li><span><a href="#">This is a link</a></span></li> <li class="menu-item-parent"><span>Not a link</span></li> <li class="menu-item-parent"><span>Not a link</span></li> <li class="menu-item-parent"><span>Not a link</span></li> </ul> </div> </body> </html> EDIT: Alright, I've changed the code to isolate the issue, and narrowed down the problem CSS. Simply adding a background image fixes the issue. The code is set up so it styles so the hit boxes for all the menu items are the same regardless if there's a link in them or not to facilitate an "onClick" drop down on those menu items without anchors. Refer to lines 81 - 86. Remove those lines (just a background image), and the hit box issue is seen in the menu items "NOT A LINK" as well. Further, the act of adding a background image fixes the hit box issue of "THIS IS A LINK" menu items. Simply add the following snippet to the CSS: .menu-navigation > li > span > a { background:url("../img/down.png") no-repeat right center; } Adding a background image, even if there is no actual image, is changing something with regards to the hit box... I'm just not sure what...

  • When I mix JSTL 1.0 and JSTL 1.1 taglib declarations, it causes a ParseException on some of my serve

    - by sangfroid
    Hello all, When I mix JSTL 1.0 and JSTL 1.1 taglib declarations, it causes a ParseException on some of my servers, but not all of them. Here is the block of code that's giving me trouble : <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%> <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%> <c:set var="TEXTVARIABLE">|STRINGOFTEXT|</c:set> <c:set var="OTHERTEXTVARIABLE">${fn:contains(TEXTVARIABLE, '|STRINGOFTEXT|')}</c:set> And here is the exception : javax.servlet.jsp.JspException: com.caucho.jsp.JspLineParseException: /WEB-INF/jsp/online/system/modules/com.MYCOMPANY.marketing/templates/common/MY_JSP_PAGE.jsp:1: tag = 'out' / attribute = 'value': An error occurred while parsing custom action attribute "value" with value "${fn:contains(TEXTVARIABLE, '|STRINGOFTEXT|')}": org.apache.taglibs.standard.lang.jstl.parser.ParseException: EL functions are not supported. However, everything works fine if I change the URI for the core declaration to http://java.sun.com/jsp/jstl/core So here's the really weird part : for some reason, mixing 1.0 and 1.1 taglib declarations only causes an exception on two of my servers -- my staging server and my production server. It causes no problems at all on my local machine or my development server. Why is this? What could possibly be causing this difference in behavior? The three servers are extremely similar in setup and configuration. The JSP page is being served up by OpenCMS, and I'm using the Caucho's Resin webserver. I understand that you don't know how my servers or CMS are set up, but really, what I'm looking for is ideas. Any ideas at all would help -- this problem has been driving me absolutely batty. Even if you don't know what could be causing the problem, if you have any suggestions at all for how I could approach the problem, that would be extremely helpful. I just don't understand what could cause this difference in behavior between my servers. For reference, here's the full stack trace : javax.servlet.jsp.JspException: com.caucho.jsp.JspLineParseException:

  • ListView adapter data change without ListView being notified

    - by brockoli
    I've written a ListActivity that has a custom list adapter. The list is being updated from a ContentProvider when onCreate is run. I also have a service that gets started when I run the app and it first updates the ContentProvider, then sends a Broadcast that the content has been updated. My ListActivity recieves the broadcast and tries to update my ListView. My problem is, I'm getting intermittent errors about the ListView adapter data changing without the ListView being notified. I call the notifyDataSetChanged() method on my list adapter right after I update it. What it seems like is happening is the list is still in the process of being updated after first call in onCreate when it recieves the broadcast from the service to update, so it tries to update my ListView before it's finished updating from it's first run. Does this make sense? Here is some of my code. NOTE: The service is working properly, it gets new data and updates my ContentProvider, and I do get the broadcast in my activity when it is updated. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ctx = this; getPrefs(); setContentView(R.layout.main); // Setup preference listener preferences = PreferenceManager.getDefaultSharedPreferences(this); preferences.registerOnSharedPreferenceChangeListener(listener); // Setup report list adapter ListView nzbLv = (ListView) findViewById(R.id.report_list); nzbla = new NZBReportListAdaptor(ctx); getReports(); nzbla.setListItems(report_list); nzbLv.setAdapter(nzbla); // Broadcast receiver to get notification from NZBService to update ReportList registerReceiver(receiver, new IntentFilter(NZBService.BROADCAST_ACTION)); startService(new Intent(ctx, NZBService.class)); } @Override public void onResume() { super.onResume(); timerHandler.resume(); new updateSabQueue().execute(); //updateList(); } @Override public void onPause() { super.onPause(); timerHandler.pause(); unregisterReceiver(receiver); } private BroadcastReceiver receiver = new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { Toast.makeText(ctx, "NZBService broadcast recieved", Toast.LENGTH_SHORT).show(); updateReportList(); } }; private void updateReportList() { new updateReportList().execute(); } private class updateReportList extends AsyncTask<Void, Void, Boolean> { /* (non-Javadoc) * @see android.os.AsyncTask#onPreExecute() * Show progress dialog */ protected void onPreExecute() { } /* (non-Javadoc) * @see android.os.AsyncTask#doInBackground(Params[]) * Get new articles from the internet */ protected Boolean doInBackground(Void...unused) { getReports(); return true; } /** * On post execute. * Close the progress dialog */ @Override protected void onPostExecute(Boolean updated) { if (updated) { Log.d(TAG, "NZB report list adapter updated"); synchronized(this) { nzbla.setListItems(report_list); } Log.d(TAG, "NZB report list notified of change"); nzbla.notifyDataSetChanged(); } } } Now that this question is answered, I will post my updated code in an effort to help others who might come across it. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ctx = this; getPrefs(); setContentView(R.layout.main); // Setup preference listener preferences = PreferenceManager.getDefaultSharedPreferences(this); preferences.registerOnSharedPreferenceChangeListener(listener); // Setup report list adapter ListView nzbLv = (ListView) findViewById(R.id.report_list); nzbla = new NZBReportListAdaptor(ctx); report_list.addAll(getReports()); nzbla.setListItems(report_list); nzbLv.setAdapter(nzbla); // Broadcast receiver to get notification from NZBService to update ReportList registerReceiver(receiver, new IntentFilter(NZBService.BROADCAST_ACTION)); startService(new Intent(ctx, NZBService.class)); } private class updateReportList extends AsyncTask<Void, Void, ArrayList<Report>> { /* (non-Javadoc) * @see android.os.AsyncTask#onPreExecute() * Show progress dialog */ protected void onPreExecute() { } /* (non-Javadoc) * @see android.os.AsyncTask#doInBackground(Params[]) * Get new articles from the internet */ protected ArrayList<Report> doInBackground(Void...unused) { return getReports(); } /** * On post execute. * Close the progress dialog */ @Override protected void onPostExecute(ArrayList<Report> updated) { nzbla.setListItems(updated); nzbla.notifyDataSetChanged(); } } private ArrayList<Report> getReports() { ArrayList<Report> reports = new ArrayList<Report>(); ContentResolver r = getContentResolver(); Cursor c = r.query(NZBReportProvider.CONTENT_URI, null, null, null, NZBReportProvider.ARTICLE_KEY_ROWID + " DESC"); startManagingCursor(c); Log.d(TAG, "NZBReport cursor.getCount=" + c.getCount()); int title = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_TITLE); int desc = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_DESCRIPTION); int cat = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_CAT); int size = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_SIZE); int link = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_LINK); int catid = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_CATID); int date = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_DATE_ADDED); int group = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_GROUP); if (c.getCount() > 0) { c.moveToFirst(); do { URL url = null; try { url = new URL(c.getString(link)); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } reports.add(new Report(c.getString(title), url, c.getString(desc), c.getString(cat), c.getString(date), c.getString(size), c.getInt(catid), c.getString(group))); } while (c.moveToNext()); } return reports; }

  • Son of Suckerfish ie6 problem - right-most dropdown menu also appearing on left side of screen

    - by Kevin Burke
    I'm interning for an NGO in India and trying to fix their website, including updating their menu so it's not the last item on the page to load, and it's centered on the screen. Everything works well enough but when I try out my new menu in IE6, I get this weird error where the content below the menu is padded an extra 30px or so and the material in the right-most drop down appears on the far left of the screen, always visible. When I drop down the rightmost link ("Publications") the content appears both in the correct location and in the same spot on the far left of the screen, and changes color when I hover as well. It's tough to describe, so it would probably be best if you took a look: visit http://sevamandir.org/a30/index.htm in your Internet Explorer 6 browser to see for yourself. I really appreciate your help. Also I'm using a 1000px wide monitor, if there's more hijinks going on outside that space I'd like to know about that too. Here's the relevant code: in the html head: <script> sfHover = function() { var sfEls = document.getElementById("nav").getElementsByTagName("LI"); for (var i=0; i<sfEls.length; i++) { sfEls[i].onmouseover=function() { this.className+=" sfhover"; } sfEls[i].onmouseout=function() { this.className=this.className.replace(new RegExp(" sfhover\\b"), ""); } } } if (window.attachEvent) window.attachEvent("onload", sfHover); </script> text surrounding the menu - the menu is simply <ul id="nav"><li></li></ul> etc. <!--begin catchphrase--> <div style="float:left; height:27px; width:520px; margin:0px; font:16px Arial, Helvetica, sans-serif; font-weight:bold; color:#769841;"> Transforming lives through democratic &amp; participatory development </div> <?php include("menu.php"); ?> </div><!-- end header --> <!--begin main text div--> <div id="maincontent"> Relevant menu CSS: #nav, #nav ul { font:bold 11px Verdana, sans-serif; float: left; width: 980px; list-style: none; line-height: 1; background: white; font-weight: bold; padding: 0; border: solid #769841; border-width: 0; margin: 0 0 1em 0; } #nav a { display: block; width: 140px; /*this is the total width of the upper menu*/ w\idth: 120px; /*this is the width less horizontal padding */ padding: 5px 10px 5px 10px; /*horiz padding is the 2nd & 4th items here - goes Top Right Bottom Left */ color: #ffffff; background:#b6791e; text-decoration: none; } #nav a.daddy { background: url(rightarrow2.gif) center right no-repeat; } #nav li { float: left; padding: 0; width: 140px; /*this needs to be updated to match top #nav a */ background:#b6791e; } #nav li:hover, #nav li a:hover, #nav li:hover a { background:#769841; } #nav li:hover li a { background:#ffffff; color:#769841; } #nav li ul { position: absolute; left: -999em; height: auto; width: 14.4em; w\idth: 13.9em; font-weight: bold; border-width: 0.25em; /*green border around dropdown menu*/ margin: 0; } #nav li ul a { background:#ffffff; color:#769841; } #nav li li { padding-right: 1em; width: 13em; background:#ffffff; } #nav li ul a { width: 13em; w\idth: 9em; } #nav li ul ul { margin: -1.75em 0 0 14em; } #nav li:hover ul ul, #nav li:hover ul ul ul, #nav li.sfhover ul ul, #nav li.sfhover ul ul ul { left: -999em; } #nav li:hover ul, #nav li li:hover ul, #nav li li li:hover ul, #nav li.sfhover ul, #nav li li.sfhover ul, #nav li li li.sfhover ul { left: auto; } #nav li:hover, #nav li.sfhover, { background: #769841; color:#ffe400; } #nav li a:hover, #nav li li a:hover, #nav li:hover li:hover, #nav li.sfhover a:hover { background: #769841; color:#ffe400; }

  • IE6 + IE7 CSS problem with overflow: hidden; - position: relative; combo.

    - by googletorp
    So I have created a slider for a homepage, that slides some images with a title and teaser text using jQuery. Everything works fine, and I went to check IE and found that IE 6 and 7 kills my slider css completely. I can't figure out why, but for some reason I can't hide the non active slides with overflow: hidden; I've tried tweaking the css back and forth, but haven't been able to figure out what's causing the problem. I've recreated the problem in a more isolated html page. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="da" lang="da" dir="ltr"> <head> <style> body { width: 900px; } .column-1 { width: 500px; float: left; } .column-2 { width: 200px; float: left; } .column-3 { width: 200px; float: left; } ul { width: 2000px; left: -499px; position: relative; } li { list-style: none; display: block; float: left; } .item-list { overflow: hidden; width: 499px; } </style> </head> <body> <div class="column-1"> <div class="item-list clearfix"> <ul> <li class="first"> <div class="node-slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 1</h4> <p>Teaser 1</p> </div> </div> </li> <li> <div class="slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 2</h4> <p>Teaser 2</p> </div> </div> </li> <li class="last"> <div class="slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 3</h4> <p>Teaser 3</p> </div> </div> </li> </ul> </div> </div> <div class="column-2"> ... </div> <div class="column-3"> ... </div> </body> </html> I've tracked down that it is the ul { position: relative; } on the ul element that is causing the overflow: hidden not to work, but why that is, I don't know. Also this is needed to make the slider javascript work using the left attribute on the ul to slide it. Any ideas as to how you can fix this is most welcome.

  • JSF2 - Why does render response not rerender component setting?

    - by fekete-kamosh
    From the tutorial: "If the request is a postback and errors were encountered during the apply request values phase, process validations phase, or update model values phase, the original page is rendered during Render response phase" (http://java.sun.com/javaee/5/docs/tutorial/doc/bnaqq.html) Does it mean that if view is restored in "Restore View" phase and then any apply request/validation/update model phase fails and skips to "Render response" that Render response only passes restored view without any changes to client?

  • Saving to SharedPreferences from custom DialogPreference

    - by Ronnie
    I've currently got a preferences screen, and I've created a custom class that extends DialogPreference and is called from within my Preferences. My preferences data seems store/retrieve from SharedPreferences without an issue, but I'm trying to add 2 more sets of settings from the DialogPreference. Basically I have two issues that I have not been able to find. Every site I've seen gives me the same standard info to save/restore data and I'm still having problems. Firstly I'm trying to save a username and password to my SharedPreferences (visible in the last block of code) and if possibly I'd like to be able to do it in the onClick(). My preferences XML that calls my DialogPreference: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory> <com.rone.optusmon.AccDialog android:key="AccSettings" android:title="Account Settings" android:negativeButtonText="Cancel" android:positiveButtonText="Save" /> </PreferenceCategory> </PreferenceScreen> My Preference Activity Class: package com.rone.optusmon; import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface; import android.os.Bundle; import android.preference.Preference; import android.preference.Preference.OnPreferenceClickListener; import android.preference.PreferenceActivity; import android.view.KeyEvent; public class EditPreferences extends PreferenceActivity { Context context = this; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); } } My Custom DialogPreference Class file: package com.rone.optusmon; import android.content.Context; import android.content.DialogInterface; import android.content.SharedPreferences; import android.preference.DialogPreference; import android.preference.PreferenceManager; import android.text.method.PasswordTransformationMethod; import android.util.AttributeSet; import android.view.View; import android.widget.CheckBox; import android.widget.CompoundButton; import android.widget.CompoundButton.OnCheckedChangeListener; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.TextView; import android.widget.Toast; public class AccDialog extends DialogPreference implements DialogInterface.OnClickListener { private TextView mUsername, mPassword; private EditText mUserbox, mPassbox; CharSequence mPassboxdata, mUserboxdata; private CheckBox mShowchar; private Context mContext; private int mWhichButtonClicked; public AccDialog(Context context, AttributeSet attrs) { super(context, attrs); mContext = context; } @Override protected View onCreateDialogView() { @SuppressWarnings("unused") LinearLayout.LayoutParams params; LinearLayout layout = new LinearLayout(mContext); layout.setOrientation(LinearLayout.VERTICAL); layout.setPadding(10, 10, 10, 10); layout.setBackgroundColor(0xFF000000); mUsername = new TextView(mContext); mUsername.setText("Username:"); mUsername.setTextColor(0xFFFFFFFF); mUsername.setPadding(0, 8, 0, 3); mUserbox = new EditText(mContext); mUserbox.setSingleLine(true); mUserbox.setSelectAllOnFocus(true); mPassword = new TextView(mContext); mPassword.setText("Password:"); mPassword.setTextColor(0xFFFFFFFF); mPassbox = new EditText(mContext); mPassbox.setSingleLine(true); mPassbox.setSelectAllOnFocus(true); mShowchar = new CheckBox(mContext); mShowchar.setOnCheckedChangeListener(mShowchar_listener); mShowchar.setText("Show Characters"); mShowchar.setTextColor(0xFFFFFFFF); mShowchar.setChecked(false); if(!mShowchar.isChecked()) { mPassbox.setTransformationMethod(new PasswordTransformationMethod()); } layout.addView(mUsername); layout.addView(mUserbox); layout.addView(mPassword); layout.addView(mPassbox); layout.addView(mShowchar); return layout; // Access default SharedPreferences SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); } public void onClick(DialogInterface dialog, int which) { mWhichButtonClicked = which; // if statement to set save/cancel button roles if (mWhichButtonClicked == -1) { Toast.makeText(mContext, "Save was clicked", Toast.LENGTH_SHORT).show(); mUserboxdata = mUserbox.getText(); mPassboxdata = mPassbox.getText(); // Save user preferences SharedPreferences settings = getDefaultSharedPreferences(this); SharedPreferences.Editor editor = settings.edit(); editor.putString("usernamekey", (String) mUserboxdata); editor.putString("passwordkey", (String) mPassboxdata); } else { Toast.makeText(mContext, "Cancel was clicked", Toast.LENGTH_SHORT).show(); } } } In my SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); line, Eclipse says "The method getDefaultSharedPreferences(AccDialog) is undefined for the type AccDialog". I've attempted to change the context to my preferences class, use a blank context and I've also tried naming my SharedPrefs and using "getSharedPreferences()" as well. I'm just not sure exactly what I'm doing here. As I'm quite new to Java/Android/coding in general, could you please be as detailed as possible with any help, eg. which of my files I need to write the code in and whereabouts in that file should I write it (i.e. onCreate(), onClick(), etc) Edit: I will need to the preferences to be Application-wide accessible, not activity-wide. Thanks

The error Log : 05-19 13:29:21.495: ERROR/DEBUGTAG(974): java.lang.NullPointerException 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.content.ComponentName.(ComponentName.java:75) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.content.Intent.(Intent.java:2551) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at com.android.booztermobile.activity.HeaderMailDisplayActivity.onClick(HeaderMailDisplayActivity.java:571) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.View.performClick(View.java:2364) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.View.onTouchEvent(View.java:4179) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.widget.TextView.onTouchEvent(TextView.java:6540) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.View.dispatchTouchEvent(View.java:3709) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at com.android.internal.policy.impl.PhoneWindow$DecorView.superDispatchTouchEvent(PhoneWindow.java:1659) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at com.android.internal.policy.impl.PhoneWindow.superDispatchTouchEvent(PhoneWindow.java:1107) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.app.Dialog.dispatchTouchEvent(Dialog.java:643) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at com.android.internal.policy.impl.PhoneWindow$DecorView.dispatchTouchEvent(PhoneWindow.java:1643) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.view.ViewRoot.handleMessage(ViewRoot.java:1691) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.os.Handler.dispatchMessage(Handler.java:99) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.os.Looper.loop(Looper.java:123) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at android.app.ActivityThread.main(ActivityThread.java:4363) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at java.lang.reflect.Method.invokeNative(Native Method) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at java.lang.reflect.Method.invoke(Method.java:521) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 05-19 13:29:21.495: ERROR/DEBUGTAG(974): at dalvik.system.NativeStart.main(Native Method) My custom Dialog : package com.android.booztermobile.services; import com.android.booztermobile.R; import android.app.Dialog; import android.content.Context; import android.os.Bundle; import android.util.Log; import android.widget.Button; public class MailDialog extends Dialog { private Button btnValid; private Button btnBack; private Button btnRestore; private Button btnModify; private Context context; public MailDialog(Context cont) { super(cont); context = cont; } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.d("TestApp", "Dialog created"); setContentView(R.layout.dialog_classement); btnValid = (Button) findViewById(R.id.btnValidClassement); btnBack = (Button) findViewById(R.id.btnBackClassement); btnRestore = (Button) findViewById(R.id.btnRestoreClassement); btnModify = (Button) findViewById(R.id.btnModifyClassement); } } and the activity (cut because too long): //create dialog public void getMailInformations(View v, Context context){ currentMail = (MailHeader) v.getTag(); dial = new MailDialog(context); dial.setTitle("Classement"); dial.show(); btnValidClassement = (Button) dial.findViewById(R.id.btnValidClassement); btnValidClassement.setOnClickListener(this); } /** the Onclick : */ public void onClick(View view) { if(view == btnValidClassement){ try{ ClassementHandlerCall classement = new ClassementHandlerCall(); boolean mailClassify = classement.classifyMail(AuthentificationActivity.uidh, String.valueOf(currentMail.getSeqnum()), null, null); dial.dismiss(); if (mailClassify == true){ // create Intent Intent defineIntentDisplayPreviousMails = new Intent(HeaderMailDisplayActivity.this, ClassementActivity.class); } }catch(Exception e){ // TODO Auto-generated catch block Log.e("DEBUGTAG","Error occured", e); e.printStackTrace(); } } }

  • Making hovor state of hidden list visible when page is active

    - by Joel
    Hi guys, One day I hope to not be such a newbie on this stuff, but some of this feels so insurmountable sometimes! OK. I have a nav bar with hidden li items that are visible when hovered over. Here's the live site: http://www.rattletree.com Here's the code for the nav: <ul id="navbar"> <li id="iex"><a href="index.php">About Rattletree</a></li> <li id="upcomgshows"><a href="upcomingshows.php">Calendar</a></li> <li id="sods"><a href="#">Sights &amp; Sounds</a> <ul class="innerlist"> <li class="innerlist"><img class="arrowAdjust" src="images/curved_arrow.png" alt="" /></li> <li class="innerlist"><a href="/playlist.m3u" target="_blank" onclick="javascript:BatmoAudioPop('Rattletree Marimba',this.href,'1'); return false">Listen</a></li> <li class="innerlist"><a href="/new_pictures.php">Photos</a></li> <li class="innerlist"><a href="/video.php">Video</a></li> <li class="innerlist"><a href="/press.php">Press</a></li> </ul> </li> <li id="bookin"><a href="#">Contact</a> <ul class="innerlist"> <li class="innerlist"><img class="arrowAdjust" src="images/curved_arrow.png" alt="" /></li> <li class="innerlist"><a href="/booking.php">Booking Info</a></li> <li class="innerlist"><a href="/media.php">Media Inquiries</a></li> </ul> </li> <li id="ste"> <a href="/sounds.php">Store</a></li> <li id="instrumes"><a href="/instruments.php">The Instruments</a></li> <li id="classe"><a href="classes.php">Workshops</a></li> </ul> css: div#navbar2 { background-color:#546F8B; border-bottom:1px solid #546F8B; border-top:1px solid #000000; display:inline-block; position:relative; width:100%; } div#navbar2 ul#navbar { color:#FFFFFF; font-family:Arial,Helvetica,sans-serif; font-size:16px; letter-spacing:1px; margin:10px 0; padding:0; white-space:nowrap; } div#navbar2 ul#navbar li ul.innerlist { color:#000000; display:none; position:relative; z-index:20; } div#navbar2 ul#navbar li { display:inline; list-style-type:none; margin:0; padding:0; position:relative; } Now it's a bit tricky what I want to do: If a user navigates to one of the innerlist pages, I'd like that innerlist ul to remain visible (with the specific li displaying the hovered state). Now I think I could figure that out on my own, but you can see on the live page that if the user is on a page from the innerlist and that list was visible, then if they hovered over the other nav tab, then those innerlists would overlap. This is a problem. Hopefully that last sentence makes sense! In short: I need to keep the inner list of the active page displaying, BUT if the user hovers over another nav button WITH it's own inner list, then the live innerlist needs to disappear. Clear as mud?

  • How can I further optimize this color difference function?

    - by aLfa
    I have made this function to calculate color differences in the CIE Lab colorspace, but it lacks speed. Since I'm not a Java expert, I wonder if any Java guru around has some tips that can improve the speed here.

  • How to hide jQuery Sub-Menus(ddsmoothmenu)?

    - by Tim
    I'm new to jQuery and i must admit that i've understood nothing yet, the syntax appears to me as an unknown language although i thought that i had my experiences with javascript. Nevertheless i managed it to implement this menu in my asp.net masterpage's header. Even got it to work that the content-page is loaded with ajax with help from here. But finally i'm failing with the menu to disappear when the new page was loaded asynchronously. I dont know how to hide this accursed jQuery Menu. Following the part of the js-file where the events are registered for hiding/disappearing. I dont know how to get the part that is responsible for it and even i dont know how to implement that part in my Anchor-onclick function where i dont have a reference to the jQuery Object. buildmenu:function($, setting){ var smoothmenu=ddsmoothmenu var $mainmenu=$("#"+setting.mainmenuid+">ul") //reference main menu UL $mainmenu.parent().get(0).className=setting.classname || "ddsmoothmenu" var $headers=$mainmenu.find("ul").parent() $headers.hover( function(e){ $(this).children('a:eq(0)').addClass('selected') }, function(e){ $(this).children('a:eq(0)').removeClass('selected') } ) $headers.each(function(i){ //loop through each LI header var $curobj=$(this).css({zIndex: 100-i}) //reference current LI header var $subul=$(this).find('ul:eq(0)').css({display:'block'}) $subul.data('timers', {}) this._dimensions={w:this.offsetWidth, h:this.offsetHeight, subulw:$subul.outerWidth(), subulh:$subul.outerHeight()} this.istopheader=$curobj.parents("ul").length==1? true : false //is top level header? $subul.css({top:this.istopheader && setting.orientation!='v'? this._dimensions.h+"px" : 0}) $curobj.children("a:eq(0)").css(this.istopheader? {paddingRight: smoothmenu.arrowimages.down[2]} : {}).append( //add arrow images '<img src="'+ (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[1] : smoothmenu.arrowimages.right[1]) +'" class="' + (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[0] : smoothmenu.arrowimages.right[0]) + '" style="border:0;" />' ) if (smoothmenu.shadow.enable){ this._shadowoffset={x:(this.istopheader?$subul.offset().left+smoothmenu.shadow.offsetx : this._dimensions.w), y:(this.istopheader? $subul.offset().top+smoothmenu.shadow.offsety : $curobj.position().top)} //store this shadow's offsets if (this.istopheader) $parentshadow=$(document.body) else{ var $parentLi=$curobj.parents("li:eq(0)") $parentshadow=$parentLi.get(0).$shadow } this.$shadow=$('<div class="ddshadow'+(this.istopheader?

Thanks, Tim EDIT: thanks to Starx' private-lesson in jQuery for beginners i solved it: I forgot the # in $("#smoothmenu1"). After that it was not difficult to find and call the hover-function from the menu's headers to let them fade out smoothly: $("#smoothmenu1").find("ul").hover(); Regards, Tim

  • Getting a NullPointerException at seemingly random intervals, not sure why

    - by Miles
    I'm running an example from a Kinect library for Processing (http://www.shiffman.net/2010/11/14/kinect-and-processing/) and sometimes get a NullPointerException pointing to this line: int rawDepth = depth[offset]; The depth array is created in this line: int[] depth = kinect.getRawDepth(); I'm not exactly sure what a NullPointerException is, and much googling hasn't really helped. It seems odd to me that the code compiles 70% of the time and returns the error unpredictably. Could the hardware itself be affecting it? Here's the whole example if it helps: // Daniel Shiffman // Kinect Point Cloud example // http://www.shiffman.net // https://github.com/shiffman/libfreenect/tree/master/wrappers/java/processing import org.openkinect.*; import org.openkinect.processing.*; // Kinect Library object Kinect kinect; float a = 0; // Size of kinect image int w = 640; int h = 480; // We'll use a lookup table so that we don't have to repeat the math over and over float[] depthLookUp = new float[2048]; void setup() { size(800,600,P3D); kinect = new Kinect(this); kinect.start(); kinect.enableDepth(true); // We don't need the grayscale image in this example // so this makes it more efficient kinect.processDepthImage(false); // Lookup table for all possible depth values (0 - 2047) for (int i = 0; i < depthLookUp.length; i++) { depthLookUp[i] = rawDepthToMeters(i); } } void draw() { background(0); fill(255); textMode(SCREEN); text("Kinect FR: " + (int)kinect.getDepthFPS() + "\nProcessing FR: " + (int)frameRate,10,16); // Get the raw depth as array of integers int[] depth = kinect.getRawDepth(); // We're just going to calculate and draw every 4th pixel (equivalent of 160x120) int skip = 4; // Translate and rotate translate(width/2,height/2,-50); rotateY(a); for(int x=0; x<w; x+=skip) { for(int y=0; y<h; y+=skip) { int offset = x+y*w; // Convert kinect data to world xyz coordinate int rawDepth = depth[offset]; PVector v = depthToWorld(x,y,rawDepth); stroke(255); pushMatrix(); // Scale up by 200 float factor = 200; translate(v.x*factor,v.y*factor,factor-v.z*factor); // Draw a point point(0,0); popMatrix(); } } // Rotate a += 0.015f; } // These functions come from: http://graphics.stanford.edu/~mdfisher/Kinect.html float rawDepthToMeters(int depthValue) { if (depthValue < 2047) { return (float)(1.0 / ((double)(depthValue) * -0.0030711016 + 3.3309495161)); } return 0.0f; } PVector depthToWorld(int x, int y, int depthValue) { final double fx_d = 1.0 / 5.9421434211923247e+02; final double fy_d = 1.0 / 5.9104053696870778e+02; final double cx_d = 3.3930780975300314e+02; final double cy_d = 2.4273913761751615e+02; PVector result = new PVector(); double depth = depthLookUp[depthValue];//rawDepthToMeters(depthValue); result.x = (float)((x - cx_d) * depth * fx_d); result.y = (float)((y - cy_d) * depth * fy_d); result.z = (float)(depth); return result; } void stop() { kinect.quit(); super.stop(); } And here are the errors: processing.app.debug.RunnerException: NullPointerException at processing.app.Sketch.placeException(Sketch.java:1543) at processing.app.debug.Runner.findException(Runner.java:583) at processing.app.debug.Runner.reportException(Runner.java:558) at processing.app.debug.Runner.exception(Runner.java:498) at processing.app.debug.EventThread.exceptionEvent(EventThread.java:367) at processing.app.debug.EventThread.handleEvent(EventThread.java:255) at processing.app.debug.EventThread.run(EventThread.java:89) Exception in thread "Animation Thread" java.lang.NullPointerException at org.openkinect.processing.Kinect.enableDepth(Kinect.java:70) at PointCloud.setup(PointCloud.java:48) at processing.core.PApplet.handleDraw(PApplet.java:1583) at processing.core.PApplet.run(PApplet.java:1503) at java.lang.Thread.run(Thread.java:637)

  • Does there exist an "idea checkout system" on the Internet?

    - by TimeSpace Traveller
    Greetings. I would like to ask the following question: is there anything on the Internet like an "idea checkout" system? Situation: I'm a software developer. Since my current job has started 2 years ago, my mentor at that time has pointed me to the open source world. I have only put little time to look at some of the open source projects, let alone any contribution. However, it is my wish to start developing something outside of the work. Well, except a little problem. I don't know what to develop! It is not about the technical knowledge; the problem is that, I am not a creative person. I am very good at analytical thinking, as well as debugging skills. When being told by my work partners to develop a solution, I could get it done without a problem. However, outside of work, I have no idea what to develop. When I look at the Internet, it seems that so many people have already been developing on so many interesting stuff, making me wonder what I could develop, so that I would not reinvent something already existed. That starts to make me wonder. On the Internet, is there anything like an "idea checkout" system or society? For example, some people would throw in as a software idea, and the system would keep it as an "inventory"; later, a potential software developer would "check out" the idea, just a how people would check out a book from the library. Then, the developer would check the "idea" back in, with a certain kind of work-in-progress or developed software, thus becoming an open-source project. I have just noticed that here at stackoverflow, there is a "Project-Ideas" tag, so perhaps that can provide me some ideas on what to develop; still, my wonder is about a system that people would provide ideas, and people would check out ideas to develop / implement into actual solution. Is there such a system or society existing anywhere on the Internet? Any input is welcome! Thank you very much. Update: Thank you for everyone who has answered my question. Certainly, "getting idea" is part of my problem; as a software developer, however, I'm concerned more than just "getting idea". What I am concerned more, as I have commented, is about the existence of such an idea exchanging ecosystem, capable to initiate open-source projects. I'll put an example here. Say, person A has an idea of music search program, but not search by the attributes of the music (composer, singer, publisher, lyrics, etc.); instead, he wants a program (and a database) to search a piece of music by melody. Very often, people only remember a piece of music by its melody, not even the name of the music (e.g. the music he wants was only once heard in a bookstore, but the melody just gets stuck in his head!). In order to find that piece, normally he would just need to blindly search for it, and spent a long time to do so. A search by melody would enable person A to find the piece much quicker. However, he would not want to personally work on it, not just because of the complexity (he is not a musician and/or programmer, knowing almost nothing about music systems in computer, search algorithms, etc.), but also legal issues (RIAA??), thus he would just like to keep the idea at some place, and let other people to work on that. Now, a developer (person B) may be at the same stage as I am right now, wishing to find something to develop, but not having an idea. With the idea exchanging ecosystem, person B will search, and somehow discover person A's music search idea, and feeling interested enough to work on it. So he "checks out" the idea, start working on it (at least a skeleton), and checks back in with the progress. An open-source project starts from here, fulfilling person A's wish, and person B's programming desire. The above is just an example, because there are already such systems exist on the Internet, but it illustrates what I think about the idea exchange system in my mind. My main concern is about idea exchanging ecosystem, not at personal and unorganized level, but at a semi-organized protocol that's specifically for software developers, having actual projects coming out as the fruits. Not about "projects", but about "ideas and product of ideas". Hopefully that would clear up some of the original idea of this question. Any input is welcome; in fact, I would like to hear as many people as possible how everyone thinks about this. Thank you very much!

  • What statistics can be maintained for a set of numerical data without iterating?

    - by Dan Tao
    Update Just for future reference, I'm going to list all of the statistics that I'm aware of that can be maintained in a rolling collection, recalculated as an O(1) operation on every addition/removal (this is really how I should've worded the question from the beginning): Obvious Count Sum Mean Max* Min* Median** Less Obvious Variance Standard Deviation Skewness Kurtosis Mode*** Weighted Average Weighted Moving Average**** OK, so to put it more accurately: these are not "all" of the statistics I'm aware of. They're just the ones that I can remember off the top of my head right now. *Can be recalculated in O(1) for additions only, or for additions and removals if the collection is sorted (but in this case, insertion is not O(1)). Removals potentially incur an O(n) recalculation for non-sorted collections. **Recalculated in O(1) for a sorted, indexed collection only. ***Requires a fairly complex data structure to recalculate in O(1). ****This can certainly be achieved in O(1) for additions and removals when the weights are assigned in a linearly descending fashion. In other scenarios, I'm not sure. Original Question Say I maintain a collection of numerical data -- let's say, just a bunch of numbers. For this data, there are loads of calculated values that might be of interest; one example would be the sum. To get the sum of all this data, I could... Option 1: Iterate through the collection, adding all the values: double sum = 0.0; for (int i = 0; i < values.Count; i++) sum += values[i]; Option 2: Maintain the sum, eliminating the need to ever iterate over the collection just to find the sum: void Add(double value) { values.Add(value); sum += value; } void Remove(double value) { values.Remove(value); sum -= value; } EDIT: To put this question in more relatable terms, let's compare the two options above to a (sort of) real-world situation: Suppose I start listing numbers out loud and ask you to keep them in your head. I start by saying, "11, 16, 13, 12." If you've just been remembering the numbers themselves and nothing more, and then I say, "What's the sum?", you'd have to think to yourself, "OK, what's 11 + 16 + 13 + 12?" before responding, "52." If, on the other hand, you had been keeping track of the sum yourself while I was listing the numbers (i.e., when I said, "11" you thought "11", when I said "16", you thought, "27," and so on), you could answer "52" right away. Then if I say, "OK, now forget the number 16," if you've been keeping track of the sum inside your head you can simply take 16 away from 52 and know that the new sum is 36, rather than taking 16 off the list and them summing up 11 + 13 + 12. So my question is, what other calculations, other than the obvious ones like sum and average, are like this? SECOND EDIT: As an arbitrary example of a statistic that (I'm almost certain) does require iteration -- and therefore cannot be maintained as simply as a sum or average -- consider if I asked you, "how many numbers in this collection are divisible by the min?" Let's say the numbers are 5, 15, 19, 20, 21, 25, and 30. The min of this set is 5, which divides into 5, 15, 20, 25, and 30 (but not 19 or 21), so the answer is 5. Now if I remove 5 from the collection and ask the same question, the answer is now 2, since only 15 and 30 are divisible by the new min of 15; but, as far as I can tell, you cannot know this without going through the collection again. So I think this gets to the heart of my question: if we can divide kinds of statistics into these categories, those that are maintainable (my own term, maybe there's a more official one somewhere) versus those that require iteration to compute any time a collection is changed, what are all the maintainable ones? What I am asking about is not strictly the same as an online algorithm (though I sincerely thank those of you who introduced me to that concept). An online algorithm can begin its work without having even seen all of the input data; the maintainable statistics I am seeking will certainly have seen all the data, they just don't need to reiterate through it over and over again whenever it changes.

  • Cascading updates with business key equality: Hibernate best practices?

    - by Traphicone
    I'm new to Hibernate, and while there are literally tons of examples to look at, there seems to be so much flexibility here that it's sometimes very hard to narrow all the options down the best way of doing things. I've been working on a project for a little while now, and despite reading through a lot of books, articles, and forums, I'm still left with a bit of a head scratcher. Any veteran advice would be very appreciated. So, I have a model involving two classes with a one-to-many relationship from parent to child. Each class has a surrogate primary key and a uniquely constrained composite business key. <class name="Container"> <id name="id" type="java.lang.Long"> <generator class="identity"/> </id> <properties name="containerBusinessKey" unique="true" update="false"> <property name="name" not-null="true"/> <property name="owner" not-null="true"/> </properties> <set name="items" inverse="true" cascade="all-delete-orphan"> <key column="container" not-null="true"/> <one-to-many class="Item"/> </set> </class> <class name="Item"> <id name="id" type="java.lang.Long"> <generator class="identity"/> </id> <properties name="itemBusinessKey" unique="true" update="false"> <property name="type" not-null="true"/> <property name="color" not-null="true"/> </properties> <many-to-one name="container" not-null="true" update="false" class="Container"/> </class> The beans behind these mappings are as boring as you can possibly imagine--nothing fancy going on. With that in mind, consider the following code: Container c = new Container("Things", "Me"); c.addItem(new Item("String", "Blue")); c.addItem(new Item("Wax", "Red")); Transaction t = session.beginTransaction(); session.saveOrUpdate(c); t.commit(); Everything works fine the first time, and both the Container and its Items are persisted. If the above code block is executed again, however, Hibernate throws a ConstraintViolationException--duplicate values for the "name" and "owner" columns. Because the new Container instance has a null identifier, Hibernate assumes it is an unsaved transient instance. This is expected but not desired. Since the persistent and transient Container objects have the same business key values, what we really want is to issue an update. It is easy enough to convince Hibernate that our new Container instance is the same as our old one. With a quick query we can get the identifier of the Container we'd like to update, and set our transient object's identifier to match. Container c = new Container("Things", "Me"); c.addItem(new Item("String", "Blue")); c.addItem(new Item("Wax", "Red")); Query query = session.createSQLQuery("SELECT id FROM Container" + "WHERE name = ? AND owner = ?"); query.setString(0, c.getName()); query.setString(1, c.getOwner()); BigInteger id = (BigInteger)query.uniqueResult(); if (id != null) { c.setId(id.longValue()); } Transaction t = session.beginTransaction(); session.saveOrUpdate(c); t.commit(); This almost satisfies Hibernate, but because the one-to-many relationship from Container to Item cascades, the same ConstraintViolationException is also thrown for the child Item objects. My question is: what is the best practice in this situation? It is highly recommended to use surrogate primary keys, and it is also recommended to use business key equality. When you put these two recommendations in to practice together, however, two of the greatest conveniences of Hibernate--saveOrUpdate and cascading operations--seem to be rendered almost completely useless. As I see it, I have only two options: Manually fetch and set the identifier for each object in the mapping. This clearly works, but for even a moderately sized schema this is a lot of extra work which it seems Hibernate could easily be doing. Write a custom interceptor to fetch and set object identifiers on each operation. This looks cleaner than the first option but is rather heavy-handed, and it seems wrong to me that you should be expected to write a plug-in which overrides Hibernate's default behavior for a mapping which follows the recommended design. Is there a better way? Am I making completely the wrong assumptions? I'm hoping that I'm just missing something. Thanks.

  • SSL confirmation dialog popup auto closes in IE8 when re-accessing a JNLP file

    - by haylem
    I'm having this very annoying problem to troubleshoot and have been going at it for way too many days now, so have a go at it. The Environment We have 2 app-servers, which can be located on either the same machine or 2 different machines, and use the same signing certificate, and host 2 different web-apps. Though let's say, for the sake of our study case here, that they are on the same physical machine. So, we have: https://company.com/webapp1/ https://company.com/webapp2/ webapp1 is GWT-based rich-client which contains on one of its screens a menu with an item that is used to invoke a Java WebStart Client located on webapp2. It does so by performing a simple window.open call via this GWT call: Window.open("https://company.com/webapp2/app.jnlp", "_blank", null); Expected Behavior User merrilly goes to webapp1 User navigates to menu entry to start the WebStart app and clicks on it browser fires off a separate window/dialog which, depending on the browser and its security settings, will: request confirmation to navigate to this secure site, directly download the file, and possibly auto-execute a javaws process if there's a file association, otherwise the user can simply click on the file and start the app (or go about doing whatever it takes here). If you close the app, close the dialog, and re-click the menu entry, the same thing should happen again. Actual Behavior On Anything but God-forsaken IE 8 (Though I admit there's also all the god-forsaken pre-IE8 stuff, but the Requirements Lords being merciful we have already recently managed to make them drop these suckers. That was close. Let's hold hands and say a prayer of gratitude.) Stuff just works. JNLP gets downloaded, app executes just fine, you can close the app and re-do all the steps and it will restart happily. People rejoice. Puppies are safe and play on green hills in the sunshine. Developers can go grab a coffee and move on to more meaningful and rewarding tasks, like checking out on SO questions. Chrome doesn't want to execute the JNLP, but who cares? Customers won't get RSI from clicking a file every other week. On God-forsaken IE8 On the first visit, the dialog opens and requests confirmation for the user to continue to webapp2, though it could be unsafe (here be dragons, I tell you). The JNLP downloads and auto-opens, the app start. Your breathing is steady and slow. You close the app, close that SSL confirmation dialog, and re-click the menu entry. The dialog opens and auto-closes. Nothing starts, the file wasn't downloaded to any known location and Fiddler just reports the connection was closed. If you close IE and reach that menu item to click it again, it is now back to working correctly. Until you try again during the same session, of course. Your heart-rate goes up, you get some more coffee to make matters worse, and start looking for plain tickets online and a cheap but heavy golf-club on an online auction site to go clubbing baby polar seals to avenge your bloodthirst, as the gates to the IE team in Redmond are probably more secured than an ice block, as one would assume they get death threats often. Plus, the IE9 and IE10 teams are already hard at work fxing the crap left by their predecessors, so maybe you don't want to be too hard on them, and you don't have money to waste on a PI to track down the former devs responsible for this mess. Added Details I have come across many problems with IE8 not downloading files over SSL when it uses a no-cache header. This was indeed one of our problems, which seems to be worked out now. It downloads files fine, webapp2 uses the following headers to serve the JNLP file: response.setHeader("Cache-Control", "private, must-revalidate"); // IE8 happy response.setHeader("Pragma", "private"); // IE8 happy response.setHeader("Expires", "0"); // IE8 happy response.setHeader("Access-Control-Allow-Origin", "*"); // allow to request via cross-origin AJAX response.setContentType("application/x-java-jnlp-file"); // please exec me As you might have inferred, we get some confirmation dialog because there's something odd with the SSL certificate. Unfortunately I have no control over that. Assuming that's only temporary and for development purposes as we usually don't get our hands on the production certs. So the SSL cert is expired and doesn't specify the server. And the confirmation dialog. Wouldn't be that bad if it weren't for IE, as other browsers don't care, just ask for confirmation, and execute as expected and consistantly. Please, pretty please, help me, or I might consider sacrificial killings as an option. And I think I just found a decently prized stainless steel golf-club, so I'm right on the edge of gore. Side Notes Might actually be related to IE8 window.open SSL Certificate issue. Though it doesn't explain why the dialog would auto-close (that really is beyong me...), it could help to not have the confirmation dialog and not need the dialog at all. For instance, I was thinking that just having a simple URL in that menu instead of have it entirely managed by GWT code to invoke a Window.open would solve the problem. But I don't have control on that menu, and also I'm very curious how this could be fixed otherwise and why the hell it happens in the first place...

  • How to associate Wi-Fi beacon info with a virtual "location"?

    - by leander
    We have a piece of embedded hardware that will sense 802.11 beacons, and we're using this to make a map of currently visible bssid -> signalStrength. Given this map, we would like to make a determination: Is this likely to be a location I have been to before? If so, what is its ID? If not, I should remember this location: generate a new ID. Now what should I store (and how should I store it) to make future determinations easier? This is for an augmented-reality app/game. We will be using it to associate particular characters and events with "locations". The device does not have internet or cellular access, so using a geolocation service is out of consideration for the time being. (We don't really need to know where we are in reality, just be able to determine if we return there.) It isn't crucial that it be extremely accurate, but it would be nice if it was tolerant to signal strength changes or the occasional missing beacon. It should be usable in relatively low numbers of access points (e.g. rural house with one wireless router) or many (wandering around a dense metropolis). In the case of a city, it should change location every few minutes of walking (continuously-overlapping signals make this a bit more tricky in naive code). A reasonable number of false positives (match a location when we aren't actually there) is acceptable. The wrong character/event showing up just adds a bit of variety. False negatives (no location match) are a bit more troublesome: this will tend to add a better-matching new location to the saved locations, masking the old one. While we will have additional logic to ensure locations that the device hasn't seen in a while will "orphan" any associated characters or events (if e.g. you move to a different country), we'd prefer not to mask and eventually orphan locations you do visit regularly. Some technical complications: signalStrength is returned as 1-4; presumably it's related to dB, but we are not sure exactly how; in my experiments it tends to stick to either 1 or 4, but occasionally we see numbers in between. (Tech docs on the hardware are sparse.) The device completes a scan of one-quarter of the channel space every second; so it takes about 4-5 seconds to get a complete picture of what's around. The list isn't always complete. (We are making strides to fix this using some slight sampling period randomization, as recommended by the library docs. We're also investigating ways to increase the number of scans without killing our performance; the hardware/libs are poorly behaved when it comes to saturating the bus.) We have only kilobytes to store our history. We have a "working" impl now, but it is relatively naive, and flaky in the face of real-world Wi-Fi behavior. Rough pseudocode: // recordLocation() -- only store strength 4 locations m_savedLocations[g_nextId++] = filterForStrengthGE( m_currentAPs, 4 ); // determineLocation() bestPoints = -inf; foreach ( oldLoc in m_savedLocations ) { points = 0.0; foreach ( ap in m_currentAPs ) { if ( oldLoc.has( ap ) ) { switch ( ap.signalStrength ) { case 3: points += 1.0; break; case 4: points += 2.0; break; } } } points /= oldLoc.numAPs; if ( points > bestPoints ) { bestLoc = oldLoc; bestPoints = points; } } if ( bestLoc && bestPoints > 1.0 ) { if ( bestPoints >= (2.0 - epsilon) ) { // near-perfect match. // update location with any new high-strength APs that have appeared bestLoc.addAPs( filterForStrengthGE( m_currentAPs, 4 ) ); } return bestLoc; } else { return NO_MATCH; } We record a location currently only when we have NO_MATCH and the app determines it's time for a new event. (The "near-perfect match" code above would appear to make it harder to match in the future... It's mostly to keep new powerful APs from being associated with other locations, but you'd think we'd need something to counter this if e.g. an AP doesn't show up in the next 10 times I match a location.) I have a feeling that we're missing some things from set theory or graph theory that would assist in grouping/classification of this data, and perhaps providing a better "confidence level" on matches, and better robustness against missed beacons, signal strength changes, and the like. Also it would be useful to have a good method for mutating locations over time. Any useful resources out there for this sort of thing? Simple and/or robust approaches we're missing?

  • Error while applying overlay on a location on a Google map in Android

One is that when I click (do a tap) on any location, the overlay is not changing to that place. Also, the app crashes when I am on the MapView page and I click on back button. What might be the error?
