• Multiple routers, subnets, gateways etc

  - by allentown

  My current setup is: Cable modem dishes out 13 static IP's (/28), a GB switch is plugged into the cable modem, and has access to those 13 static IP's, I have about 6 "servers" in use right now. The cable modem is also a firewall, DHCP server, and 3 port 10/100 switch. I am using it as a firewall, but not currently as a DHCP server. I have plugged into the cable modem, two network cables, one which goes to the WAN port of a Linksys Dual Band Wireless 10/100/1000 router/switch. Into the linksys are a few workstations, a few printers, and some laptops connecting to wifi. I set the Linksys to use take static IP, and enabled DHCP for the workstations, printers, etc in 192.168.1.1/24. The network for the Linksys is mostly self contained, backups go to a SAN, on that network, it all happens through that switch, over GB. But I also get internet access from it as well via the cable modem using one static IP. This all works, however, I can not "see" the static IP machines when I am on the Linksys. I can get to them via ssh and other protocols, and if I want to from "outside", I open holes, like 80, 25, 587, 143, 22, etc. The second wire, from the cable modem/fireall/switch just uplinks to the managed GB switch. What are the pros and cons of this? I do not like giving up the static IP to the Linksys. I basically have a mixed network of public servers, and internal workstations. I want the public servers on public IP's because I do not want to mess with port forwarding and mappings. Is it correct also, that if someone breaches the Linksys wifi, they still would have a hard time getting to the static IP range, just by nature of the network topology? Today, just for a test, I toggled on the DHCP in the firewall/cable modem at 10.1.10.1/24 range, the Linksys is n the 192.168.1.100/24 range. At that point, all the static IP machines still had in and out access, but Linksys was unreachable. The cable modem only has 10/100 ports, so I will not plug anything but the network drop into it, which is 50Mb/10Mb. Which makes me think this could be less than ideal, as transfers from the workstation network to the server network will be bottlenecked at 100Mb when I have 1000Mb available. I may not need to solve that, if isolation is better though. I do not move a lot of data, if any, from Linsys network to server network, so for it to pretend to be remote is ok. Should I approach this any different? I could enable DHCP on the cable modem/firewall, it should still send out the statics to the GB switch, but will also be a DHCP in 10.1.10.1/24 range? I can then plug the Linksys into the GB switch, which is now picking up statics and the 10.1.10.1/24 ranges, tell the Linksys to use 10.1.10.5 or so. Now, do I disable DHCP on the Linksys, and the cable modem/firewall will pass through the statics and 10.0.10.1/24 ranges as well? Or, could I open a second DHCP pool on the Linksys? I guess doing so gives me network isolation again, but it is just the reverse of what I have now. But I get out of the bottleneck, not that the Linksys could ever really touch real GB speeds anyway, but the managed switch certainly can. This is all because 13 statics are not that many. Right now, 6 "servers", the Linksys, a managed switch, a few SSL certs, and I am running out. I do not want to waste a static IP on the managed GB switch, or the Linksys, unless it provides me some type of benefit. Final question, under my current setup, if I am on a workstation, sitting at 192.168.1.109, the Linksys, with GB, and I send a file over ssh to the static IP machine, is that literally leaving the internet, and coming back in, or does it stay local? To me it seems like: Workstation (192.168.1.109) -> Linksys DHCP -> Linksys Static IP -> Cable Modem -> Server ( and it hits the 10/100 ports on the cable modem, slowing me down. But does it round trip the network, leave and come back in, limiting me to the 50/10 internet speeds? *These are all made up numbers, I do not use default router IP's as I will one day add a VPN, and do not want collisions. I need some recommendations, do I want one big network, or two isolated ones. Printers these days need an IP, everything does, I can not get autoconf/bonjour to be reliable on most printers. but I am also not sure I want the "server" side of my operation to be polluted by the workstation side of my operation. Unless there is some magic subetting I have not learned yet, here is what I am thinking: Cable modem 10/100, has 13 static IP, publicly accessible -> Enable DHCP on the cable modem -> Cable modem plugs into managed switch -> Managed switch gets 10.1.10.1 ssh, telnet, https admin management address -> Managed switch sends static IP's to to servers -> Plug Linksys into managed switch, giving it 10.1.10.2 static internally in Linksys admin -> Linksys gets assigned 10.1.10.x as its DHCP sending range -> Local printers, workstations, iPhones etc, connect to this -> ( Do I enable DHCP or disable it on the Linksys, just define a non over lapping range, or create an entirely new DHCP at 10.1.50.0/24, I think I am back isolated again with that method too? ) Thank you for any suggestions. This is the first time I have had to deal with less than a /24, and most are larger than that, but it is just a drop to a cabinet. Otherwise, it's a router, a few repeaters, and soho stuff that is simple, with one IP. I know a few may suggest going all DHCP on the servers, and I may one day, just not now, there has been too much moving of gear for me to be interested in that, and I would want something in the Catalyst series to deal with that.

• CustomListAdapter Problem in Android? How???

  - by Praveen Chandrasekaran

  i want to improve the list view's performance. this is the code for my getView method in my Adapter? public View getView(int arg0, View text_view_name, ViewGroup parent) { try { if (text_view_name == null) { text_view_name = mInflater.inflate( R.layout.bs_content_list_item1, null); text_view_name.setTag(R.id.text1_detail1, text_view_name .findViewById(R.id.text1_detail1)); text_view_name.setTag(R.id.text3_detail1, text_view_name .findViewById(R.id.text3_detail1)); text_view_name.setTag(R.id.eve_img_detail1, text_view_name .findViewById(R.id.eve_img_detail1)); } text1 = (TextView) text_view_name.getTag(R.id.text1_detail1); // text2 = (TextView) text_view_name.getTag(R.id.text2); text3 = (TextView) text_view_name.getTag(R.id.text3_detail1); img = (ImageView) text_view_name.getTag(R.id.eve_img_detail1); text1.setText(VAL1[arg0]); text3.setText(VAL3[arg0]); if (!mBusy) { img_value = new URL(VAL4[arg0]); mIcon11 = BitmapFactory.decodeStream(img_value.openConnection() .getInputStream()); img.setImageBitmap(mIcon11); text_view_name.setTag(R.id.eve_img_detail1, null); } else { img.setImageResource(R.drawable.icon); text_view_name.setTag(R.id.eve_img_detail1, text_view_name .findViewById(R.id.eve_img_detail1)); } } catch (Exception e) { name = "Exception in MultiLine_bar_details1 getView"; Log.v(TAG, name + e); } return text_view_name; } this is the code for scrollstatechanged method: public void onScrollStateChanged(AbsListView view, int scrollState) { switch (scrollState) { case OnScrollListener.SCROLL_STATE_IDLE: try { MultiLine_bar_details1.mBusy = false; int first = view.getFirstVisiblePosition(); int count = view.getCount(); for (int i = 0; i < count; i++) { ImageView t = (ImageView) view.getChildAt(i); if (t.getTag(R.id.eve_img_detail1) != null) { MultiLine_bar_details1.img_value = new URL( MultiLine_bar_details1.VAL4[first + i]); MultiLine_bar_details1.mIcon11 = BitmapFactory .decodeStream(MultiLine_bar_details1.img_value .openConnection().getInputStream()); MultiLine_bar_details1.img.setImageBitmap(MultiLine_bar_details1.mIcon11); t.setTag(R.id.eve_img_detail1, null); } } } catch (Exception e) { Log.v(TAG, "Idle" + e); } // mStatus.setText("Idle"); break; case OnScrollListener.SCROLL_STATE_TOUCH_SCROLL: MultiLine_bar_details1.mBusy = true; break; case OnScrollListener.SCROLL_STATE_FLING: MultiLine_bar_details1.mBusy = true; break; } } this is very complicated for me to get the output properly. actually i have the listview with custom adapter. that icons makes the listview scroll very slow.i am getting the images for icons from the image urls. upto this(above code) i can improve the scroll performance of my list view. but the image icons are not proper in the corresponding order. its dynamically changing when i scroll the listview.. i refered the commonsware busy coder guide and this blog. My very Big question is "How can we access the single view in scrollstatechanged parameter AbsListView? " what is the problem in it? how to do it better? Any Idea?

• iPhone dev - viewDidUnload subviews

  - by Mk12

  I'm having a hard time undestand a couple of the methods in UIViewController, but first I'll say what I think they are meant for (ignoring interface builder because I'm not using it): -init: initialize non view-related stuff that won't need to be released in low memory situations (i.e. not objects or objects that can't be recreated easily). -loadView: create the view set the [self view] property. -viewDidLoad: Create all the other view elements -viewDidUnload: Release objects created in -viewDidLoad. didReceiveMemoryWarning: Low-memory situation, release unnecessary things such as cached data, if this view doesn't have a superview then the [super didReceiveMemoryWarning] will go on to release (unload) the view and call -viewDidUnload. -dealloc: release everything -viewWillAppear:, -viewDidAppear:, -viewWillDisappear:, -viewDidDisappear: self-explanatory, not necessary unless you want to respond (do something) to those events. I'm not sure about a couple of things. First, the Apple docs say that when -viewDidUnload is called, the view has already been released and set to nil. Will -loadView get called again to recreate the view later on? There's a few things I created in -viewDidLoad that I didn't make a ivar/property for because there is no need and it will be retained by the view (because they are subviews of it). So when the view is released, it will release those too, right? When the view is released, will it release all its subviews? Because all the objects I created in -viewDidLoad are subviews of [self view]. So if they already get released why release them again in -viewDidUnload? I can understand data that is necessary when the view is visible being loaded and unloaded in these methods, but like I asked, why release the subviews if they already get released? EDIT: After reading other questions, I think I might have got it (my 2nd question). In the situation where I just use a local variable, alloc it, make it a subview and release, it will have a retain count of 1 (from adding it as a subview), so when the view is released it is too. Now for the view elements with ivars pointing to them, I wasn't using properties because no outside class would need to access them. But now I think that that's wrong, because in this situation: // MyViewController.h @interface MyViewController : UIViewController { UILabel *myLabel; } // MyViewController.m . . . - (void)viewDidLoad { myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 40, 10)]; [myLabel setText:@"Foobar"]; [[self view] addSubview:myLabel]; } - (void)viewDidUnload [ // equivalent of [self setMyLabel:nil]; without properties [myLabel release]; myLabel = nil; } In that situation, the label will be sent the -release message after it was deallocated because the ivar didn't retain it (because it wasn't a property). But with a property the retain count would be two: the view retaining it and the property. So then in -viewDidUnload it will get deallocated. So its best to just always use properties for these things, am I right? Or not? EDIT: I read somewhere that -viewDidLoad and -viewDidUnload are only for use with Interface Builder, that if you are doing everything programmatically you shouldn't use them. Is that right? Why?

• Unable to show Desktop Notifications using Google Chrome

  - by Praveen Kumar

  I followed the instructions as given in Using The Notifications API. Also I faced many problems like the below, because I added the document.querySelector() inside the <head> part: Uncaught TypeError: Cannot call method 'addEventListener' of null Now I have the below source, where I am able to Check Notification Support, and Check Notification Permissions links. Guide me how to bring in notifications in a simpler way. Also, I tried this: $("#html").click(function() { if (window.webkitNotifications.checkPermission() == 0) { createNotificationInstance({ notificationType: 'html' }); } else { window.webkitNotifications.requestPermission(); } }); Now I am stuck with this source. I need to generate HTML & Simple Notifications. Am I missing something? Please guide me. Source: <!DOCTYPE HTML> <html lang="en-US"> <head> <meta charset="UTF-8"> <title>Desktop Notifications</title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script type="text/javascript"> function checkNotifications() { if (window.webkitNotifications) alert("Notifications are supported!"); else alert("Notifications are not supported for this Browser/OS version yet."); } function createNotificationInstance(options) { if (window.webkitNotifications.checkPermission() == 0) { // 0 is PERMISSION_ALLOWED if (options.notificationType == 'simple') { return window.webkitNotifications.createNotification('icon.png', 'Notification Title', 'Notification content...'); } else if (options.notificationType == 'html') { return window.webkitNotifications.createHTMLNotification('http://localhost/'); } } else { window.webkitNotifications.requestPermission(); } } </script> <style type="text/css"> * {font-family: Verdana, sans-serif;} body {font-size: 10pt; margin: 0; padding: 0;} p {margin: 5px;} a {color: #09f; text-decoration: none;} a:hover {color: #f00;} </style> </head> <body> <p><strong>Desktop Notifications</strong></p> <p>Lets see how the notifications work in this browser.</p> <p> <a href="#" onclick="checkNotifications(); return false;">Check Notification Support</a>. Next <a href="#" onclick="alert('Notifications are ' + ((window.webkitNotifications.checkPermission() == 0) ?

• Change default markers for directions on google maps

  - by Elaine Marley

  I'm a complete noob with google maps api and I started with a given script that I'm editing to what I need to do. In this case I have a map with some points in it that come from a database. They are like this (after I get the lat/lng from the database): var route1 = 'from: 37.496764,-5.913379 to: 37.392587,-6.00023'; var route2 = 'from: 37.392587,-6.00023 to: 37.376964,-5.990838'; routes = [route1, route2]; Then my script does the following: for(var j = 0; j < routes.length; j++) { callGDirections(j); document.getElementById("dbg").innerHTML += "called "+j+"<br>"; } And then the directions: function callGDirections(num) { directionsArray[num] = new GDirections(); GEvent.addListener(directionsArray[num], "load", function() { document.getElementById("dbg").innerHTML += "loaded "+num+"<br>"; var polyline = directionsArray[num].getPolyline(); polyline.setStrokeStyle({color:colors[num],weight:3,opacity: 0.7}); map.addOverlay(polyline); bounds.extend(polyline.getBounds().getSouthWest()); bounds.extend(polyline.getBounds().getNorthEast()); map.setCenter(bounds.getCenter(),map.getBoundsZoomLevel(bounds)); }); // === catch Directions errors === GEvent.addListener(directionsArray[num], "error", function() { var code = directionsArray[num].getStatus().code; var reason="Code "+code; if (reasons[code]) { reason = reasons[code] } alert("Failed to obtain directions, "+reason); }); directionsArray[num].load(routes[num], {getPolyline:true}); } The thing is, I want to change the A and B markers that I get from google on the map to the ones for each of the points that I'm using (each has it's particular icon in the database) but I don't know how to do this. Furthermore, what would be fantastic but I'm clueless if it's even possible is the following: when I get the directions I get something like this: (a) Street A directions (b) Street B And I want (a) Name of first point directions (b) Name of second point (also from database) I understand that my knowledge of the subject is very lacking and the question might be a bit vague, but I would appreciate any tip pointing me in the right direction. EDIT: Ok, I learned a lot from the google api with this problem but I'm still far from what I need. I learned how to hide the default markers doing this: // Hide the route markers when signaled. GEvent.addListener(directionsArray[num], "addoverlay", hideDirMarkers); // Not using the directions markers so hide them. function hideDirMarkers(){ var numMarkers = directionsArray[num].getNumGeocodes() for (var i = 0; i < numMarkers; i++) { var marker = directionsArray[num].getMarker(i); if (marker != null) marker.hide(); else alert("Marker is null"); } } And now when I create new markers doing this: var point = new GLatLng(lat,lng); var marker = createMarker(point,html); map.addOverlay(marker); They appear but they are not clickable (the popup with the html won't show)

• JSTL c:forEach causes @ViewScoped bean to invoke @PostConstruct on every request

  - by Nitesh Panchal

  Hello, Again i see that the @PostConstruct is firing every time even though no binding attribute is used. See this code :- <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:c="http://java.sun.com/jsp/jstl/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form> <c:forEach var="item" items="#{TestBean.listItems}"> <h:outputText value="#{item}"/> </c:forEach> <h:commandButton value="Click" actionListener="#{TestBean.actionListener}"/> </h:form> </h:body> </html> And this is the simplest possible bean in JSF :- package managedBeans; import java.io.Serializable; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; @ManagedBean(name="TestBean") @ViewScoped public class TestBean implements Serializable { private List<String> listItems; public List<String> getListItems() { return listItems; } public void setListItems(List<String> listItems) { this.listItems = listItems; } public TestBean() { } @PostConstruct public void init(){ System.out.println("Post Construct fired!"); listItems = new ArrayList<String>(); listItems.add("Mango"); listItems.add("Apple"); listItems.add("Banana"); } public void actionListener(){ System.out.println("Action Listener fired!"); } } Do you see any behaviour that should cause postconstruct callback to fire each time? I think JSF 2.0 is highly unstable. If it has to fire PostConstruct each and every time what purpose does @ViewScoped serve. Why not to use @RequestScoped only? I thought i have made some mistake in my application. But when i created this simplest possible in JSF, i still get this error. Am i not understanding the scopes of JSF? or are they not testing it properly? Further, if you remove c:forEach and replace it with ui:repeat, then it works fine. Waiting for replies to confirm whether it is bug or it is intentional to stop the programmers from using jstl?

• Making a non-trivial Image and Video Gallery with a really nice interface

  - by Cawas

  Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

• Search Form in Responsive Design - Remove Search button on Mobile

  - by Kevin

  I'm working with a search box in the header of a responsive website. On desktop/tablet widths, there's a search input field and a styled 'search' button to the right. You can type in a search term and either click 'SEARCH' button or just hit enter on the keyboard with the same result. When you scale down to mobile widths, the search input field fills the width of the screen. The submit button falls below it. On a desktop, clicking the button or hitting enter activate the search. On an actual iphone phone, you can hit the 'SEARCH' button, but the native mobile keyboard that rises from the bottom of the screen has a search button where the enter/return key would normally be. It seems to know I'm in a form and the keyboard automatically gives me the option to kick off the search by basically hitting the ENTER key location....but it says SEARCH. So far so good. I figure I don't need the button in the header on mobile since it's already in the keyboard. Therefore, I'll hide the button on mobile widths and everything will be tighter and look better. So I added this to my CSS to hide it in mobile: #search-button {display: none;} But now the search doesn't work at all. On mobile, I don't get the option in the keyboard that showed up before and if I just hit enter, it doesn't work at all. On desktop at mobile width, hitting enter also not longer works. So clearly by hiding the submit/search button, the phone no longer gave me the native option to run the search. In addition, on the desktop at mobile width, even hitting enter inside the search input box also fails to launch the the search. Here's my search box: <form id="search-form" method="get" accept-charset="UTF-8, utf-8" action="search.php"> <fieldset> <div id="search-wrapper"> <label id="search-label" for="search">Item:</label> <input id="search" class="placeholder-color" name="item" type="text" placeholder="Item Number or Description" /> <button id="search-button" title="Go" type="submit"><span class="search-icon"></span></button> </div> </fieldset> </form> Here's what my CSS looks like: #search-wrapper { float: left; display: inline-block; position: relative; white-space: nowrap; } #search-button { display: inline-block; cursor: pointer; vertical-align: top; height: 30px; width: 40px; } @media only screen and (max-width: 639px) { #search-wrapper { display: block; margin-bottom: 7px; } #search-button { /* this didn't work....it hid the button but the search failed to load */ display: none;*/ } } So.....how can I hide this submit button when I'm on a mobile screen, but still let the search run from the mobile keyboard or just run by hitting enter when in the search input box. I was sure that putting display:none on the search button at mobile width would do the trick, but apparently not. Thanks...

• FFmpeg creates emtpy (black) frames

  - by resamsel

  I have a set of images from a timelapse shot (172 JPG files) that I want to convert into a movie. I tried several parameters with FFmpeg, but all I get is a video with black frames (though it has the expected length). ffmpeg -f image2 -vcodec mjpeg -y -i img_%03d.jpg timelapse2.mpg The command above creates this video: http://sdm-net.org/data/timelapse2.mpg What I'm expecting is something like this (created with Time Lapse Assembler.app): https://vimeo.com/39038362 - This is my fallback option, but I'd really like to create timelapse movies from a script. I'm on OSX Lion (10.7.3) with FFmpeg version (0.10) installed via Homebrew. I also tried to find a proper version of mencoder for OSX, but this doesn't seem to be an easy task. Also, ImageMagick's convert doesn't seem to work nicely, it creates really bad output and it seems there's not much I can do about it...

• JQuery Help: slidetoggle() is not working properly

  - by John Smith

  Hi all, I'm trying to use JQuery Slidetoggle functionality, but not able to use properly. The problem I'm currently facing is my div is sliding down on the click of slide image icon, but after that suddenly data div (in which data is loading) disappears. Means sliding down is perfect but div (in which data is loading , here #divMain) is not visible after that. I want to achieve sliding effect in my code, like this has (Please see Website Design, Redesign Services slider): Here is my code: HTML: <div> <div class="jquery_inner_mid"> <div class="main_heading"> <a href="#"> <img src="features.jpg" alt="" title="" border="0" /></a> </div> <div class="plus_sign"> <img id="imgFeaturesEx" src="images/plus.jpg" alt="" title="" border="0" /> <img id="imgFeaturesCol" src="images/minus.jpg" alt="" title="" border="0" /></div> <div class="toggle_container"> <div id="divMain" > </div> </div> </div> <div class="jquery_inner_mid"> <div class="main_heading"> <img src="About.jpg" alt="" title="" /></div> <div class="plus_sign"> <img id="imgTechnoEx" src="images/plus.jpg" alt="" title="" border="0" /> <img id="imgTechnoCol" src="images/minus.jpg" alt="" title="" border="0" /></div> <div class="toggle_container"> <div id="divTechnossus" > </div> </div> </div> </div> JQuery: $(function() { $('#imgFeaturesCol').hide(); $('#imgTechnoCol').hide(); $('#imgFeaturesEx').click(function() { $.getJSON("/Visitor/GetFeatureInfo", null, function(strInfo) { $('#divMain').html(strInfo).slideToggle("slow"); LoadDiv(); }); $('#imgFeaturesEx').hide(); $('#imgFeaturesCol').show(); }); $('#imgFeaturesCol').click(function() { $('#divMain').html("").slideToggle("slow"); $('#imgFeaturesCol').hide(); $('#imgFeaturesEx').show(); }); $('#imgTechnoEx').click(function() { $.getJSON("/Visitor/GetTechnossusInfo", null, function(strInfo) { $('#divTechnossus').html(strInfo).slideToggle("slow"); }); $('#imgTechnoEx').hide(); $('#imgTechnoCol').show(); }); $('#imgTechnoCol').click(function() { $('#divTechnossus').html("").slideToggle("slow"); $('#imgTechnoCol').hide(); $('#imgTechnoEx').show(); }); })(); function LoadDiv() { $('#s4').cycle({ speed: 200, timeout: 0, pager: '#nav' }); }

• Modern alternatives to Java

  - by Ralph

  I have been a Java developer for 14 years and have written an enterprise-level (~500 kloc) Swing application that uses most of the standard library APIs. Recently, I have become disappointed with the progress that the language has made to "modernize" itself, and am looking for an alternative for ongoing development. I have considered moving to the .NET platform, but I have issues with using something the only runs well in Windows (I know about Mono, but that is still far behind Microsoft). I also plan on buying a new Macbook Pro as soon as Apple releases their new rumored Arrandale-based machines and want to develop in an environment that will feel "at home" in Unix/Linux. I have considered using Python or Ruby, but the standard Java library is arguably the largest of any modern language. In JVM-based languages, I looked at Groovy, but am disappointed with its performance. Rumor has it that with the soon-to-be released JDK7, with its InvokeDynamic instruction, this will improve, but I don't know how much. Groovy is also not truly a functional language, although it provides closures and some of the "functional" features on collections. It does not embrace immutability. I have narrowed my search down to two JVM-based alternatives: Scala and Clojure. Each has its strengths and weaknesses. I am looking for opinions. I am not an expert at either of these languages; I have read 2 1/2 books on Scala and am currently reading Stu Halloway's book on Clojure. Scala is strongly statically typed. I know the dynamic language folks claim that static typing is a crutch for not doing unit testing, but it does provide a mechanism for compile-time location of a whole class of errors. Scala is more concise than Java, but not as much as Clojure. Scala's inter-operation with Java seems to be better than Clojure's, in that most Java operations are easier to do in Scala than in Clojure. For example, I can find no way in Clojure to create a non-static initialization block in a class derived from a Java superclass. For example, I like the Apache commons CLI library for command line argument parsing. In Java and Scala, I can create a new Options object and add Option items to it in an initialization block as follows (Java code): final Options options = new Options() { { addOption(new Option("?", "help", false, "Show this usage information"); // other options } }; I can't figure out how to the same thing in Clojure (except by using (doit...)), although that may reflect my lack of knowledge of the language. Clojure's collections are optimized for immutability. They rarely require copy-on-write semantics. I don't know if Scala's immutable collections are implemented using similar algorithms, but Rich Hickey (Clojure's inventor) goes out of his way to explain how that language's data structures are efficient. Clojure was designed from the beginning for concurrency (as was Scala) and with modern multi-core processors, concurrency takes on more importance, but I occasionally need to write simple non-concurrent utilities, and Scala code probably runs a little faster for these applications since it discourages, but does not prohibit, "simple" mutability. One could argue that one-off utilities do not have to be super-fast, but sometimes they do tasks that take hours or days to complete. I know that there is no right answer to this "question", but I thought I would open it up for discussion. Are there other JVM-based languages that can be used for enterprise level development?

• [C#] Not enough memory or not enough handles?

  - by Nayan

  I am working on a large scale project where a custom (pretty good and robust) framework has been provided and we have to use that for showing up forms and views. There is abstract class StrategyEditor (derived from some class in framework) which is instantiated whenever a new StrategyForm is opened. StrategyForm (a customized window frame) contains StrategyEditor. StrategyEditor contains StrategyTab. StrategyTab contains StrategyCanvas. This is a small portion of the big classes to clarify that there are many objects that will be created if one StrategyForm object is allocated in memory at run-time. My component owns all these classes mentioned above except StrategyForm whose code is not in my control. Now, at run-time, user opens up many strategy objects (which trigger creation of new StrategyForm object.) After creating approx. 44 strategy objects, we see that the USER OBJECT HANDLES (I'll use UOH from here onwards) created by the application reaches to about 20k+, while in registry the default amount for handles is 10k. Read more about User Objects here. Testing on different machines made it clear that the number of strategy objects opened is different for message to pop-up - on one m/c if it is 44, then it can be 40 on another. When we see the message pop-up, it means that the application is going to respond slowly. It gets worse with few more objects and then creation of window frames and subsequent objects fail. We first thought that it was not-enough-memory issue. But then reading more about new in C# helped in understanding that an exception would be thrown if app ran out of memory. This is not a memory issue then, I feel (task manager also showed 1.5GB+ available memory.) M/C specs Core 2 Duo 2GHz+ 4GB RAM 80GB+ free disk space for page file Virtual Memory set: 4000 - 6000 My questions Q1. Does this look like a memory issue and I am wrong that it is not? Q2. Does this point to exhaustion of free UOHs (as I'm thinking) and which is resulting in failure of creation of window handles? Q3. How can we avoid loading up of an StrategyEditor object (beyond a threshold, keeping an eye on the current usage of UOHs)? (we already know how to fetch number of UOHs in use, so don't go there.) Keep in mind that the call to new StrategyForm() is outside the control of my component. Q4. I am bit confused - what are Handles to user objects exactly? Is MSDN talking about any object that we create or only some specific objects like window handles, cursor handles, icon handles? Q5. What exactly cause to use up a UOH? (almost same as Q4) I would be really thankful to anyone who can give me some knowledgeable answers. Thanks much! :)

• String from Httpresponse not passing full value.

  - by Shekhar_Pro

  HI i am in desperate need for help here, I am making a web request and getting a json string with Response.ContentLenth=2246 but when i parse it in a string it gives only few 100 characters, i traked it down that it is only getting values less than 964. strings length is still 2246 but remaining values are just (\0) null characters. Its also giving an error Unterminated string passed in. (2246): at following line FacebookFeed feed = sr.Deserialize<FacebookFeed>(data); It works fine if the response stream contains characters less than 964 chars. Following is the extract from the full code error encountered in last line. System.Web.Script.Serialization.JavaScriptSerializer sr = new System.Web.Script.Serialization.JavaScriptSerializer(); System.Net.HttpWebRequest req = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(@"https://graph.facebook.com/100000570310973_181080451920964"); req.Method = "GET"; System.Net.HttpWebResponse res = (System.Net.HttpWebResponse)req.GetResponse(); byte[] resp = new byte[(int)res.ContentLength]; res.GetResponseStream().Read(resp, 0, (int)res.ContentLength); string data = Encoding.UTF8.GetString(resp); FacebookFeed feed = sr.Deserialize<FacebookFeed>(data); error given is Unterminated string passed in.

• Yet another bug of JSF?

  - by Nitesh Panchal

  Hello, Again i see that the @PostConstruct is firing every time even though no binding attribute is used. See this code :- <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:c="http://java.sun.com/jsp/jstl/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form> <c:forEach var="item" items="#{TestBean.listItems}"> <h:outputText value="#{item}"/> </c:forEach> <h:commandButton value="Click" actionListener="#{TestBean.actionListener}"/> </h:form> </h:body> </html> And this is the simplest possible bean in JSF :- package managedBeans; import java.io.Serializable; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; @ManagedBean(name="TestBean") @ViewScoped public class TestBean implements Serializable { private List<String> listItems; public List<String> getListItems() { return listItems; } public void setListItems(List<String> listItems) { this.listItems = listItems; } public TestBean() { } @PostConstruct public void init(){ System.out.println("Post Construct fired!"); listItems = new ArrayList<String>(); listItems.add("Mango"); listItems.add("Apple"); listItems.add("Banana"); } public void actionListener(){ System.out.println("Action Listener fired!"); } } Do you see any behaviour that should cause postconstruct callback to fire each time? I think JSF 2.0 is highly unstable. If it has to fire PostConstruct each and every time what purpose does @ViewScoped serve. Why not to use @RequestScoped only? I thought i have made some mistake in my application. But when i created this simplest possible in JSF, i still get this error. Am i not understanding the scopes of JSF? or are they not testing it properly? Further, if you remove c:forEach and replace it with ui:repeat, then it works fine. Waiting for replies to confirm whether it is bug or it is intentional to stop the programmers from using jstl?

• How can I tell the size of my app during development?

  - by Newbyman

  My programming decissions are directly related to how much room I have left, or worse perhaps how much I need to shave off in order to get up the 10mb limit. I have read that Apple has quietly increased the 3G & Edge download limit from 10mb up to 20mb in preparation for the iPad in April. Either way, my real question is how can I gauge a rough estimate of how large my app will end while I'm still in the development phase? Is the file size of my development folder roughly 1 to 1 ratio? Is the compressed file size of my development a better approximation? My .xcodeproj file is only a couple hundred kB, but the size of my folder is 11.8 MB. I have a .sqlite database, less than 20 small png images and a Settings.Bundle. The rest are unknown Xcode files related to build, build for iphoneOS, simulator etc.... My source code is rather large with around 1000 lines in most of the major controllers, all in all around 48 .h&.m files. But my classes folder inside my development folder is less than 800kb. Digging around inside my Build file, there is lots of iphone simulator files and debugging files which I don't think will contribute to the final product. The Application file states that it is around 2.3 MB. However, this is such a large difference from the 11.8 MB, I have to wonder if this is just another piece of the equation. I have the app on the my device, I'm in the testing phase. Therefore, I though that I would try to see how large the working version was on the device by checking in iTunes, however my development app is visible on the right-hand the application's iphone screen, but no information about the app most importantly its size. I also checked in Organizer, I used the lower portion of the screen-(Applications), found my application and selected the drop down arrow which gave my "Application Data" and a download arrow button to the right to save a file on my desktop, named with the unique AppleID. Inside the folder it had three folders-(documents, library, tmp) the documents had a copy of my .sqlite database, the library a few more files but not anything obvious or of size, and the tmp was empty. All in all the entire folder was only 164kb-which tells me that this is not the right place to find the size either. I understand that the size is considered to be the size of my binary plus all the additional files and images that I have add. Does anyone have a effective way of guaging how large the binary is or the relating the development folder size to what the final App Store application size will end up. I know that questions have been posted with similar aspects, but I could not find any answered post that really described...what files, or how to determine size specifically. I know that this question looks like a book, but I just wanted to be specific in conveying exactly what I'm looking for and the attempts thus far. *Note all files are unzipped and still in regular working Xcode order of a single app with no brought-in builds or referenced projects. I'm sure that this is straight forward, I just don't know where to look?

• [Android] Force close when trying to parse JSON with AsyncTask in the background

  - by robs

  Hello everyone, i'm new to android development and i'm playing around with json data. I managed to get the parsing to work.

• How to open a server port outside of an OpenVPN tunnel with a pf firewall on OSX (BSD)

  - by Timbo

  I have a Mac mini that I use as a media server running XBMC and serves media from my NAS to my stereo and TV (which has been color calibrated with a Spyder3Express, happy). The Mac runs OSX 10.8.2 and the internet connection is tunneled for general privacy over OpenVPN through Tunnelblick. I believe my anonymous VPN provider pushes "redirect_gateway" to OpenVPN/Tunnelblick because when on it effectively tunnels all non-LAN traffic in- and outbound. As an unwanted side effect that also opens the boxes server ports unprotected to the outside world and bypasses my firewall-router (Netgear SRX5308). I have run nmap from outside the LAN on the VPN IP and the server ports on the mini are clearly visible and connectable. The mini has the following ports open: ssh/22, ARD/5900 and 8080+9090 for the XBMC iOS client Constellation. I also have Synology NAS which apart from LAN file serving over AFP and WebDAV only serves up an OpenVPN/1194 and a PPTP/1732 server. When outside of the LAN I connect to this from my laptop over OpenVPN and over PPTP from my iPhone. I only want to connect through AFP/548 from the mini to the NAS. The border firewall (SRX5308) just works excellently, stable and with a very high throughput when streaming from various VOD services. My connection is a 100/10 with a close to theoretical max throughput. The ruleset is as follows Inbound: PPTP/1723 Allow always to 10.0.0.40 (NAS/VPN server) from a restricted IP range >corresponding to possible cell provider range OpenVPN/1194 Allow always to 10.0.0.40 (NAS/VPN server) from any Outbound: Default outbound policy: Allow Always OpenVPN/1194 TCP Allow always from 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) OpenVPN/1194 UDP Allow always to 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) Block always from NAS to any On the Mini I have disabled the OSX Application Level Firewall because it throws popups which don't remember my choices from one time to another and that's annoying on a media server. Instead I run Little Snitch which controls outgoing connections nicely on an application level. I have configured the excellent OSX builtin firewall pf (from BSD) as follows pf.conf (Apple App firewall tie-ins removed) (# replaced with % to avoid formatting errors) ### macro name for external interface. eth_if = "en0" vpn_if = "tap0" ### wifi_if = "en1" ### %usb_if = "en3" ext_if = $eth_if LAN="{10.0.0.0/24}" ### General housekeeping rules ### ### Drop all blocked packets silently set block-policy drop ### all incoming traffic on external interface is normalized and fragmented ### packets are reassembled. scrub in on $ext_if all fragment reassemble scrub in on $vpn_if all fragment reassemble scrub out all ### exercise antispoofing on the external interface, but add the local ### loopback interface as an exception, to prevent services utilizing the ### local loop from being blocked accidentally. ### set skip on lo0 antispoof for $ext_if inet antispoof for $vpn_if inet ### spoofing protection for all interfaces block in quick from urpf-failed ############################# block all ### Access to the mini server over ssh/22 and remote desktop/5900 from LAN/en0 only pass in on $eth_if proto tcp from $LAN to any port {22, 5900, 8080, 9090} ### Allow all udp and icmp also, necessary for Constellation. Could be tightened. pass on $eth_if proto {udp, icmp} from $LAN to any ### Allow AFP to 10.0.0.40 (NAS) pass out on $eth_if proto tcp from any to 10.0.0.40 port 548 ### Allow OpenVPN tunnel setup over unprotected link (en0) only to VPN provider IPs ### and port ranges pass on $eth_if proto tcp from any to a.b.8.0/24 port 1194:1201 ### OpenVPN Tunnel rules. All traffic allowed out, only in to ports 4100-4110 ### Outgoing pings ok pass in on $vpn_if proto {tcp, udp} from any to any port 4100:4110 pass out on $vpn_if proto {tcp, udp, icmp} from any to any So what are my goals and what does the above setup achieve? (until you tell me otherwise :) 1) Full LAN access to the above ports on the mini/media server (including through my own VPN server) 2) All internet traffic from the mini/media server is anonymized and tunneled over VPN 3) If OpenVPN/Tunnelblick on the mini drops the connection, nothing is leaked both because of pf and the router outgoing ruleset. It can't even do a DNS lookup through the router. So what do I have to hide with all this? Nothing much really, I just got carried away trying to stop port scans through the VPN tunnel :) In any case this setup works perfectly and it is very stable. The Problem at last! I want to run a minecraft server and I installed that on a separate user account on the mini server (user=mc) to keep things partitioned. I don't want this server accessible through the anonymized VPN tunnel because there are lots more port scans and hacking attempts through that than over my regular IP and I don't trust java in general. So I added the following pf rule on the mini: ### Allow Minecraft public through user mc pass in on $eth_if proto {tcp,udp} from any to any port 24983 user mc pass out on $eth_if proto {tcp, udp} from any to any user mc And these additions on the border firewall: Inbound: Allow always TCP/UDP from any to 10.0.0.40 (NAS) Outbound: Allow always TCP port 80 from 10.0.0.40 to any (needed for online account checkups) This works fine but only when the OpenVPN/Tunnelblick tunnel is down. When up no connection is possbile to the minecraft server from outside of LAN. inside LAN is always OK. Everything else functions as intended. I believe the redirect_gateway push is close to the root of the problem, but I want to keep that specific VPN provider because of the fantastic throughput, price and service. The Solution? How can I open up the minecraft server port outside of the tunnel so it's only available over en0 not the VPN tunnel? Should I a static route? But I don't know which IPs will be connecting...stumbles How secure would to estimate this setup to be and do you have other improvements to share? I've searched extensively in the last few days to no avail...If you've read this far I bet you know the answer :)

• How to make condition inside getView of Custom BaseAdapter

  - by user1501150

  I want to make a Custom ListView with Custom BaseAdapter, where the the status=1,I want to show a CheckBox, and else I want to show a textView.. My given condition is: if (NewtheStatus == 1) { alreadyOrderText .setVisibility(TextView.GONE); } else{ checkBox.setVisibility(CheckBox.GONE); } But Some times I obtain some row that has neither checkBox nor TextView.

• c++ and c# speed compared

  - by Mack

  I was worried about C#'s speed when it deals with heavy calculations, when you need to use raw CPU power. I always thought that C++ is much faster than C# when it comes to calculations. So I did some quick tests. The first test computes prime numbers < an integer n, the second test computes some pandigital numbers. The idea for second test comes from here: Pandigital Numbers C# prime computation: using System; using System.Diagnostics; class Program { static int primes(int n) { uint i, j; int countprimes = 0; for (i = 1; i <= n; i++) { bool isprime = true; for (j = 2; j <= Math.Sqrt(i); j++) if ((i % j) == 0) { isprime = false; break; } if (isprime) countprimes++; } return countprimes; } static void Main(string[] args) { int n = int.Parse(Console.ReadLine()); Stopwatch sw = new Stopwatch(); sw.Start(); int res = primes(n); sw.Stop(); Console.WriteLine("I found {0} prime numbers between 0 and {1} in {2} msecs.", res, n, sw.ElapsedMilliseconds); Console.ReadKey(); } } C++ variant: #include <iostream> #include <ctime> int primes(unsigned long n) { unsigned long i, j; int countprimes = 0; for(i = 1; i <= n; i++) { int isprime = 1; for(j = 2; j < (i^(1/2)); j++) if(!(i%j)) { isprime = 0; break; } countprimes+= isprime; } return countprimes; } int main() { int n, res; cin>>n; unsigned int start = clock(); res = primes(n); int tprime = clock() - start; cout<<"\nI found "<<res<<" prime numbers between 1 and "<<n<<" in "<<tprime<<" msecs."; return 0; } When I ran the test trying to find primes < than 100,000, C# variant finished in 0.409 seconds and C++ variant in 5.553 seconds. When I ran them for 1,000,000 C# finished in 6.039 seconds and C++ in about 337 seconds. Pandigital test in C#: using System; using System.Diagnostics; class Program { static bool IsPandigital(int n) { int digits = 0; int count = 0; int tmp; for (; n > 0; n /= 10, ++count) { if ((tmp = digits) == (digits |= 1 << (n - ((n / 10) * 10) - 1))) return false; } return digits == (1 << count) - 1; } static void Main() { int pans = 0; Stopwatch sw = new Stopwatch(); sw.Start(); for (int i = 1; i <= 123456789; i++) { if (IsPandigital(i)) { pans++; } } sw.Stop(); Console.WriteLine("{0}pcs, {1}ms", pans, sw.ElapsedMilliseconds); Console.ReadKey(); } } Pandigital test in C++: #include <iostream> #include <ctime> using namespace std; int IsPandigital(int n) { int digits = 0; int count = 0; int tmp; for (; n > 0; n /= 10, ++count) { if ((tmp = digits) == (digits |= 1 << (n - ((n / 10) * 10) - 1))) return 0; } return digits == (1 << count) - 1; } int main() { int pans = 0; unsigned int start = clock(); for (int i = 1; i <= 123456789; i++) { if (IsPandigital(i)) { pans++; } } int ptime = clock() - start; cout<<"\nPans:"<<pans<<" time:"<<ptime; return 0; } C# variant runs in 29.906 seconds and C++ in about 36.298 seconds. I didn't touch any compiler switches and bot C# and C++ programs were compiled with debug options. Before I attempted to run the test I was worried that C# will lag well behind C++, but now it seems that there is a pretty big speed difference in C# favor. Can anybody explain this? C# is jitted and C++ is compiled native so it's normal that a C++ will be faster than a C# variant. Thanks for the answers!

• How to get data from struts2 action with jQuery?

  - by Rafa Romero

  I have an Struts2 Web with GoogleMaps. I want to load a list of markers which are saved in a SQL DDBB. To do this, I tried with jQuery and Ajax. Here you are the code: loadMarkers.java public class loadMarkers extends ActionSupport implements ServletRequestAware,ServletResponseAware{ //Variables de sesion/cookie FunctionClass ses; protected HttpServletResponse servletResponse; protected HttpServletRequest servletRequest; private String userID=""; //Variables del marker private List<marker> markersList = new ArrayList<marker>(); public String execute() throws Exception{ FunctionClass friends = new FunctionClass(); //Leemos de la cookie for(Cookie c : servletRequest.getCookies()) { if (c.getName().equals("userID")) userID = (c.getValue()); } System.out.println("en el loadMarkers"); connectionBBDD con = new connectionBBDD(); markersList = con.loadMarkers(userID); return SUCCESS; } I want to use the markerList array in Javascript, to create the markers. This is the struts.xml file: <package name="jsonActions" namespace="/test" extends="json-default"> <action name="LoadMarkers" class="web.localizadroid.maps.loadMarkers"> <interceptor-ref name="basicStack"/> <result type="json"> <param name="root">markersList</param> </result> </action> </package> And here you are the Javascript (jQuery) code: function loadMarkersJ(){ alert("dentro"); $.ajax({ type : "post", url : "LoadMarkers", dataType: "json", success : function(data) { alert(data); var image = new google.maps.MarkerImage ('http://i53.tinypic.com/ettquh.png'); var jSon_Object = eval("(" + data + ")"); //For para analizar los datos (Json) obtenidos de la BBDD for (x = 0; x < jSon_Object.length; x++) { var markersArray = []; var myLatlng = new google.maps.LatLng(jSon_Object[x].lat, jSon_Object[x].lon); markerLoaded = new google.maps.Marker( { position : myLatlng, map : map, icon: image, title: "NOMBRE: " + jSon_Object[x].tarjetName + "\n" + "ANOTACIONES: " + jSon_Object[x].anotaciones + "\n" + "TIME: " + jSon_Object[x].time }); markersArray.push(markerLoaded); if (markersArray) { for (i in markersArray) { alert("entro en forColocaMarkers"); if (markersArray[i].getAnimation() != null) { markersArray[i].setAnimation(null); } else { markersArray[i].setAnimation(google.maps.Animation.BOUNCE); } markersArray[i].setMap(map); } } } } }); } From success : function(data) { to the end, is JavaScript code to create de markers, and this it's OK. The problem is whith ajax, because I don't get to obtain markerList Array by jSon data return...I think that the problem is in the url attribute from $.ajax...I tried loadMarkers.action and loadMarkers, but nothing happens. When I execute the web, only prints the alert alert("dentro"), the alert alert(data) never has been printed. I have forgotten to add the code where I call the Javascript function (loadMarkersJ). Here you are: <p><s:a action="LoadMarkers.action" namespace="/test" onclick="loadMarkersJ(this)">Cargar Marcadores S</s:a></p> Somebody can help me please?

  - by Surender Rathore

  I am sending push notification on device which has iOS 5.0.1, but notification is not received on iOS5 device. If i try to send notification on iOS4.3.3 device, it received on this device. My server is developed in c# and apple push notification certificate is used in .p12 format. My code to register the notification is - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. // Set the navigation controller as the window's root view controller and display. deviceToken = nil; self.window.rootViewController = self.navigationController; [self.window makeKeyAndVisible]; [[UIApplication sharedApplication] enabledRemoteNotificationTypes]; [[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert]; return YES; } - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken { UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"Succeeded in registering for APNS" message:@"Sucess" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alertView show]; [alertView release]; deviceToken = [devToken retain]; NSMutableString *dev = [[NSMutableString alloc] init]; NSRange r; r.length = 1; unsigned char c; for (int i = 0; i < [deviceToken length]; i++) { r.location = i; [deviceToken getBytes:&c range:r]; if (c < 10) { [dev appendFormat:@"0%x", c]; } else { [dev appendFormat:@"%x", c]; } } NSUserDefaults *def = [NSUserDefaults standardUserDefaults]; [def setObject:dev forKey:@"DeviceToken"]; [def synchronize]; NSLog(@"Registered for APNS %@\n%@", deviceToken, dev); [dev release]; } - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { NSLog(@"Failed to register %@", [error localizedDescription]); UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"FAILED" message:@"Fail" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alertView show]; [alertView release]; deviceToken = nil; } - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { NSLog(@"Recieved Remote Notification %@", userInfo); NSDictionary *aps = [userInfo objectForKey:@"aps"]; NSDictionary *alert = [aps objectForKey:@"alert"]; //NSString *actionLocKey = [alert objectForKey:@"action-loc-key"]; NSString *body = [alert objectForKey:@"body"]; // NSMutableArray *viewControllers = [NSMutableArray arrayWithArray:[self.navigationController viewControllers]]; // // if ([viewControllers count] > 2) { // NSRange r; // r.length = [viewControllers count] - 2; // r.location = 2; // [viewControllers removeObjectsInRange:r]; // // MapViewController *map = (MapViewController*)[viewControllers objectAtIndex:1]; // [map askDriver]; // } // // [self.navigationController setViewControllers:viewControllers]; // [viewControllers release]; //NewBooking,"BookingId",Passenger_latitude,Passenger_longitude,Destination_latitude,Destination_longitude,Distance,Time,comments NSArray *arr = [body componentsSeparatedByString:@","]; if ([arr count]>0) { MapViewController *map = (MapViewController*)[[self.navigationController viewControllers] objectAtIndex:1]; [map askDriver:arr]; [self.navigationController popToViewController:[[self.navigationController viewControllers] objectAtIndex:1] animated:YES]; } //NSString *sound = [userInfo objectForKey:@"sound"]; //UIAlertView *alertV = [[UIAlertView alloc] initWithTitle:actionLocKey // message:body delegate:nil // cancelButtonTitle:@"Reject" // otherButtonTitles:@"Accept", nil]; // // [alertV show]; // [alertV release]; } Can anyone help me out with this issue. Why notification received on iOS4.3 device but not on iOS5? Thank you very much!!! in advance

• WPF MVVM TreeView item source losing context after command

  - by user3955716

  I have a treeview which contains files, every view model holds an item source which is an ObservableCollection with files items: public ObservableCollection<CMItemFileNode> SubItemNode On each item i have context menu options (Delete, Execute..). If i move from one viewModel to another the ObservableCollection of files updated correctly and presented correctly but, when i perform a context menu command like delete file item, the command execute good but when i move to another view model (which holds SubItemNode ObservableCollection of is own) after the command executed the WPF still thinks i'm in the last view model i was in and not the one i'm really on. Very important to mention is that when i update to .net 4.5 (which unfortunantly i can't do) everything is ok and the ObservableCollection addresses the correct view model. Here is the treeView: <TreeView x:Name="Files" Margin="0,5,5,0" Grid.Row="6" Grid.Column="2" ItemsSource="{Binding SubItemNode}" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch" Height="300" Grid.RowSpan="6" Width="300" dd:DragDrop.IsDragSource="True" dd:DragDrop.IsDropTarget="True" dd:DragDrop.DropHandler="{Binding}" dd:DragDrop.UseDefaultDragAdorner="True"> <TreeView.Resources> <Style TargetType="{x:Type TreeView}"> <Setter Property="local:CMTreeViewFilesBehavior.IsTreeViewFilesBehavior" Value="True"/> </Style> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected}" /> <Setter Property="local:CMTreeViewFilesItemBehavior.IsTreeViewFilesItemBehavior" Value="True"/> </Style> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" /> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black" /> </TreeView.Resources> <TreeView.ContextMenu> <ContextMenu> <MenuItem Header="View File" Command="{Binding ExecuteFileCommand}" /> <Separator /> <MenuItem Header="Delete all" Command="{Binding DeleteAllFilesCommand}" /> <MenuItem Header="Delete selected" Command="{Binding DeleteSelectedFilesCommand}" /> </ContextMenu> </TreeView.ContextMenu> <TreeView.ItemTemplate> <HierarchicalDataTemplate ItemsSource="{Binding SubItemNode}" > <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <Image Grid.Column="0" Margin="2" Width="32" Height="18" Source="{Binding Path=Icon}" HorizontalAlignment="Left" VerticalAlignment="Center" /> <TextBlock Text="{Binding Path=Name}" Grid.Column="1" Margin="2" VerticalAlignment="Center" Foreground="{Binding Path=Status, Converter={StaticResource ItemFileStatusToColor}}" FontWeight="{Binding Path=IsSelected, Converter={StaticResource BoolToFontWidth}}"/> </Grid> </HierarchicalDataTemplate> </TreeView.ItemTemplate> </TreeView> Am I doing somthing wrong? and why in .net 4.5 it works well ?
