• Eclipse plugin: Custom icon for a Marker

  - by Itay

  I want to specify a custom icon for a makrer. Sadly, the icon that I chose is not displayed. Here's the relevant parts of the plugin.xml file (the project id "x"): <extension id="xmlProblem" name="XML Problem" point="org.eclipse.core.resources.markers"> <super type="org.eclipse.core.resources.problemmarker"/> <persistent value="true"> </persistent> </extension> <extension point="org.eclipse.ui.ide.markerImageProviders"> <imageprovider markertype="x.xmlProblem" icon="icons/marker.png" id="xmlProblemImageProvider"> </imageprovider> </extension> I also tried specifying a class (implementing IMarkerImageProvider) instead of an icon, but that getImagePath() method of the class does not get called. Any thoughts on how to make custom marker icons work? Desperately, yours. -Itay

• Custom Silverlight button with <Path> content and visual states

  - by Klay

  I would like to create a button control that has a Path element as its content--an IconButton if you will. This button should fulfill two conditions: 1. The Path element's stroke and fill colors should be available for manipulation by the VisualStateManager. 2. The Path element's data string (which defines it's shape) can be set in code or in XAML, so that I can create several such buttons without creating a new custom control for each. The only way I can see to do it would involve no XAML whatsoever. That is, setting all the visual states and animations in the code behind, plus generating the Geometry objects point by point (and not being able to use the convenient Data string property on the Path element). Is there a simpler way to do this?

• Trace() method doesnt work in FlashDevelop

  - by numerical25

  When I put a trace("test"); at the entry point of my flashdevelop project and run it. The application runs fine but I do not see the trace in the output. Below is my code package { import flash.display.Sprite; import flash.events.Event; /** * ... * @author Anthony Gordon */ public class Main extends Sprite { public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { trace("test"); removeEventListener(Event.ADDED_TO_STAGE, init); // entry point var game:Game = new Game(stage); addChild(game); } }

• Is Transport security a bad practice for the WCF service over the Internet?

  - by Sergey

  Hello, I have a WCF service accessible over the Internet. It has wsHttpBinding binding and message security mode with username credentials to authenticate clients. The msdn says that we should use message security for the Internet scenarios, because it provides end-to-end security instead of point-to-point security as Transport security has. What if i use transport security for the wcf service over the Internet? Is it a bad practice? Could my data be seen by malicious users? Thanks, Sergey

• C# Sequence Diagramm Reverse Engineering Tool?

  - by Wayne

  It's essential for me to find a tool that will reverse engineer sequence diagrams by integrating with the debugger. I suppose using the profiler could work also but less desirable. It's a key requirement that the tool in question will record all threads of execution since the app, TickZoom, is heavily parallelized. We just evaluated a most awesome tool from Sparx called Enterprise Architect which integrates with the debugger. It allows you to set a break point, start recording method traces from that break point. It's a lovely design and GUI. Hope it works for you but it only records a single thread of execution so that makes it unusable for us. I will put in a feature request to Sparx. But hope to find a similar tool that does this now since that's the only features we need--not all the other stuff that Sparx also does rather well. Sincerely, Wayne

• XAML2CPP 1.0.1.0

  - by Valter Minute

  I upgraded XAML2CPP to fix some bugs and support some new features that will be used in my next tutorial step (that I hope to publish very soon!). Bug fixed: the listbox selection changed event was generated with an incorrect prototype events generated by the XAML tree root element (UserControl) were not handled. New features: XAML2CPP generates panels (dynamically generated XAML subtrees that may be added to a page) and user controls (those will be the object of my next post, stay tuned!). XAML2CPPXRValue class has been added to XAML2CPPbase.h. This class will allow single-line declaration of XRValue objects (I’m lazy!) and destroys automatically objects and string XRValues when the object itself is destroyed. You can download the latest XAML2CPP release here: http://cid-9b7b0aefe3514dc5.skydrive.live.com/self.aspx/.Public/XAML2CPP.zip

• I cannot search/find any applications in the Dash on 12.04

  - by Russell

  Its been a while since I booted my Ubuntu (12.04), but when i did I had several updates (over 100) and I installed them along with rebooting. These updates seemed to mess with my video driver but I seemed to have fixed this. My problem is that my applications do not show anywhere. I can open them via terminal or if there are shortcuts (such as on the toolbar) but if I hit Super and go to Apps, there is nothing. This is true if I hit Super and search any app name nothing will come back (except for files). I need help to understand what happened! Also for some reason I can't upgrade to 12.10 (I assume because I have 12.04 and not 12.04.1, which I don't understand how to get).

• Ubuntu Slows down over time?

  - by Lucas McCoy

  About a few months ago I was using Ubuntu (doing something in the command line) when it started lagging really bad. I would hit S (or any other key) and like 20 seconds later it would show up in my terminal. Naturally I killed the machine and rebooted. The system started working just fine, but about 30 minutes later it did the same thing. Now I'm forced to use Ubuntu in 30 minute spurts. I've looked at my running processes and none of them are taking large amounts of CPU or RAM. Luckily I've dual-booted so I could still use my machine. Now I need to get this fixed and I'm wondering what my options are. Will I be forced to do a fresh install or is there another way?

• Bastion unexpectedly exits when I move my cursor

  - by user69358

  I downloaded the Humble Indie Bundle V, mostly because my friend told me about how great Bastion was. When I first installed it, I was getting the seemingly common "black screen" error that most people got (fixed that half with this http://ubuntuforums.org/showthread.php?p=11992661). But I also have an error where every time I move my cursor, in any direction, any amount, the game closes instantly. I can use the keyboard no problem, but without fail, every time I move my mouse, it crashes. Does anyone know what might be causing this? Has anyone encountered anything like this before? I am worried it may be a hardware issue, but hoping someone might be able to help me out. I'm running Ubuntu 12.04 on a Dell Studio 1558. Graphics card is the stock Intel graphics card, running on 4 GB of RAM.

• Eclipse plugins for Spring / Hibernate development?

  - by es11

  I have a running dynamic web project in Eclipse (Java EE + Maven + Spring). I am at the point where I need to integrate a persistence layer and want to use Hibernate with a mySql database. I am wonder what plugins would be useful for me at this point? For Hibernate should I install hibernate tools or is it not necessary? Are then any plugins that are most widely use for connecting / exploring database connections that would be appropriate for the type of project I am working on? Thanks.

• How to pass GET parameters to rewritten URL?

  - by Jakobud

  I have an .htaccess rewrite rule like this: RewriteCond %{SCRIPT_FILENME} !-d RewriteCond %{SCRIPT_FILENAME} !-f RewriteRule ^search/(.*)$ search.php?q=$1 What this does is, if someone visits http://www.mysite.com/search/test the URI that is really processed is http://www.mysite.com/search.php?q=test. Now, if I try to pass an extra random GET parameter to my rewritten URL, the parameter is ignored. So if I try to do visit here: http://www.mysite.com/search/whatever?extra=true The parameter extra is ignored. It doesn't seem to get passed at all. Can this problem be fixed? If so, how?

• MGTwitterEngine - Using getImageAtURL on iPhone

  - by Andrew Malchow

  Essentially, I'm working on asynchronously downloading images and adding them to specific UITableView cells (twitter profile images using MGTwitterEngine from Matt Gemmell). I've looked at general asynchronous download code and must admit, I'm still too much of a noob to understand it well enough to adapt it to my purposes. Instead, I'm attempting to use Gemmell's included getImageAtUrl method to add the images. I have it working to the point that -imageReceived: receives the images for visible cells, however, I'm stuck as to how to include them into the appropriate cells at that point. - (void)imageReceived:(UIImage *)image forRequest:(NSString *)identifier { NSLog(@"Got an image:%@",image); // What goes here? Or elsewhere? } This method is within my main view controller, I also have a custom cell controller where I'm drawing the cell content using Loren Brichter's fast scrolling code. Any help with this MGTwitterEngine method in particular, or with dynamically adding these images to my table cells would be greatly appreciated.

• Best memory allocation strategy for iOS ?

  - by Mr.Gando

  Hey guys, I'm debating myself about memory allocation on iOS. I write most of my code in C++ and I really like using ObjectPools, FreeLists, etc. In order to pre-allocate a lot of the stuff that I'll be constantly "alloc/dealloc" during the course of my game, ( like particles, game entities, etc ). Still on iOS, it's not like we are developing for a console like PSP, where I can know for fact that I'll get a fixed amount of memory. iOS , will issue "memory warnings" when the system needs memory. Does anyone have some suggestions about this ? Is it too serious since the new iPod touch/iPhone 4 are carrying more RAM ? or it's still a big concern ? Thanks!

• Ubuntu 14.04 ATI/Intel Hybrid Graphics DPM

  - by anchit123

  I have a Dell Inspiron 3521 with hybrid ATI/Intel graphics. (AMD Radeon 7670M / Intel HD 4000) using Ubuntu 14.04 with open source drivers for graphics. (xserver-xorg-video-ati) I read that Ubuntu 14.04 with the linux kernel version 3.13 supports auto switching between graphics and dynamic power management. Is it correct? Anyway, if it is true, I dont think that it is working in my system , because fan runs constantly and battery backup is less than 2 hours. lspci | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series] (rev ff) What should I do? Is there any hope that this gets fixed in future kernels?

• Web P2P video confrence solution

  - by dtroy

  I'm looking for the best possible solution which will allow me to incorporate live video/audio conference between 2 users(only 2 at this point) into a flash gaming platform. The video chat is not just an extra feature, it's the main one. I'm mainly looking at open source implementations or something I'll be able to implement myself, but will consider commercial products if they are exactly what I need. Here are a few things I've looked at, but so far, I didn't find any of them good enough: Flash player 10's P2P capabilities sound promising, but I am aware of the fact that Adobe has not release any information on the RTMFP protocol and that there is no commercial server which supports it at this point. Stream all the video/audio live through a flash server (not p2p), but from my personal experience you don't get a smooth conversation. I think TokBox uses this method Java applets are a possible solution too (to perform p2p), but I don't think it will be a nice and elegant solution to combine them in the game at this point (and requires the user to authorize them). BTW, I couldn't find any useful implementations. So, If you know of any, i'll look into them. Google Gmail Video Chat uses a custom (and proprietary) browser plug-in which does the p2p and streams the video/audio into the flash player. This is a possible solution, but I rather not implement the entire p2p protocol stack + browser plug-in at this stage and concentrate on other aspect of the game itself. I think they are using XMPP based protocol similar to Jingle and they've release a Jingle librarby but without the video confrencing implementation. EDIT: In response to Branden: I am aware of Adobe Stratus. Stratus is a beta, hosted rendezvous service that aids establishing communications between Flash Player endpoints (RTMFP server). This current release of the Stratus is prerelease and is designed for evaluation purposes only. The service is not final. There is no guarantee that the service will continue to exist in the future or any information about the future cost. That's why I don't think it can be used as a commercial solution. At least not yet. I'd appreciate your suggestions and advice. thanks!

• OpenGl es view and uitableview

  - by Mel

  I have written an application using opengl es view. Now I want to add a uitableview to display on the screen. However I am needing some guidance on how opengl es view and the other views play together nice. For example I have read some things that would lead me to think I need to pause the opengl view when the table is displayed. Can anyone point me to a tutorial on how to make these things work together or just point me to the stackoverflow question that I can't find where some guy asked the same exact thing and got an answer :-)

• How to get Magento to update order status when PayPal returns IPN message?

  - by Nick

  When someone checks out in Magento with PayPal, and PayPal flags their payment for review, Magento correctly sets the order status to "Payment Review". However, if after a day or two PayPal decides the order is OK, it sends an IPN message to Magento with the proper payment status of "Pending" and pending reason of "authorization". I can see this IPN message in Magento's paypal logs (and can simulate it with the sandbox), however, when Magento receives this message it does not update its order status. Why not and how can this be fixed? I am using Magento 1.5.1.0.

• Adobe flash plug-in crashed/needs permission in Chromium

  - by sally

  A couple of days ago I started to get these messages when trying to watch videos on Youtube and a couple of other sites. (Using Chromium browser) Normally starts by just seeing a black screen with Missing Plug-in faintly visible, but will also ask me to give permission to run both at top (yellow bar), and if I tell it to 'allow' it follows up with the white puzzle piece on black background requesting permission. Occasionally I have seen the message telling me the flash-player has crashed, too. Giving permission does not fix the problem. Have also navigated to 'about:plugins' and checked that Adobe flash is enabled and permitted. I have just done a fresh installation of Lubuntu 11.10 as a last resort but problem still not fixed.

• SQL SERVER – Puzzle Involving NULL – Resolve – Error – Operand data type void type is invalid for sum operator

  - by pinaldave

  Today is Monday let us start this week with interesting puzzle. Yesterday I had also posted quick question here: SQL SERVER – T-SQL Scripts to Find Maximum between Two Numbers Run following code: SELECT SUM(data) FROM (SELECT NULL AS DATA) t It will throw following error. Msg 8117, Level 16, State 1, Line 1 Operand data type void type is invalid for sum operator. I can easily fix if I use ISNULL Function as displayed following. SELECT SUM(data) FROM (SELECT ISNULL(NULL,0) AS DATA) t Above script will not throw an error. However, there is one more method how this can be fixed. Can you come up with another method which will not generate error?

• Samsung NP305U1A laptop won't resume from suspension

  - by Oskar Pålsson

  I just bought a Samsung NP305U1A laptop and installed Ubuntu Desktop 12.04 LTS on it. Whenever I suspend the computer and try to wake it back up, the monitor only shows a black screen and the only thing I can do is a hard reset. Kernel: 3.2.0-24-generic Graphic: Radeon HD 6320 Anybody know what to do? UPDATE I did some some research and remebered that I installed the "ATI/AMD proprietary FGLRX graphics driver" from the "Additional drivers" software bundled in Ubuntu. I also tried to install the "ATI/AMD proprietary FGLRX graphics driver (post-release updates)" but whenever I do, it gives me an error and I can't continue So I decided to make a clean install of Ubuntu 12.04 again and when i tried the suspension out-of-the-box, it did work. But since I can't install the drivers I need, HD video is choppy like hell. So perhaps the suspension bug was fixed in the post-release updates of the driver, but sadly I cannot install them, and I don't know why.

• How to display images from SD card in a GalleryView

  - by OceanBlue

  I am trying to display all the images stored in SD card in a Gallery View. I have tried using the content provider (android.provider.MediaStore.images.Media class), but seem to be getting stuck at a point. Not sure if this is the way to go about it. Here is my code so far: String[] colsNeeded = new String[]{Media._ID, Media.TITLE}; Uri mMedia = Media.EXTERNAL_CONTENT_URI; //Create a cursor using the URI & column names needd Cursor c = managedQuery(mMedia, colsNeeded, null, null, Media.DATE_TAKEN + " ASC"); //What kind of adapter should I create here //that contains images from the cursor?? SpinnerAdapter sa = null; //This is the point I get stuck //Set the adapter of the gallery view Gallery galleryPetPhotos = (Gallery)findViewById(R.id.GalleryPetPhotos); galleryPetPhotos.setAdapter(sa); Just a nudge in the right direction would be greatly appreciated.

• Testing loses its effectiveness if all programmers don't use them

  - by Jeff O

  Let's assume you are convinced that the extra time spent unit testing has merit and improves production. Does that still hold up when everyone working on the same code doesn't use them? This question makes me wonder if fixing tests that everyone doesn't use is a waste of time. If you correct a test so the new code will pass, you're assuming the new code is correct. The person updating the test better have a firm understanding of the reasoning behind the code change and decide if the test or the new code needs to be fixed. This much inconsistency in a team when it comes to testing is probably an indication of other problems as well. There is a certain amount of risk involved that someone else on the team will alter code that is covered by testing. Is this the point where testing becomes counter-productive?

First time the application show the map but wen i change the lat long and try to invalidate the mapview using diff lat long, map is not refreshed. Below is my code please have a look and suggest accordingly: //Source code protected void onCreate(Bundle icicle) { // TODO Auto-generated method stub super.onCreate(icicle); setContentView(R.layout.main); infoTextView = (TextView) findViewById(R.id.infoTextView); // Finding Current Location locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1l, 1l, this); Location location = locationManager.getLastKnownLocation("gps"); // mock location by hard-code if DDMS has not sent a fake loc to the emulator. if (location == null) { lat = 13.6972 * 1E6; lng = 100.5150 * 1E6; } else { // get real location if can retrieve the location sent by DDMS or GPS lat = location.getLatitude() * 1E6; lng = location.getLongitude() * 1E6; } setGPSLocation(lat, lng); } //This is the function which I am calling with different lat and long public void setGPSLocation(Double lati, Double longi) { lat = lati; lng = longi; System.out.println("Latitude :"+ lat +" Longitude :"+lng); // Prepare text being shown String tmpLoc = LOC_INFO_TEMPLATE; tmpLoc = tmpLoc.replace("lg", String.valueOf(lng)); tmpLoc = tmpLoc.replace("lt", String.valueOf(lat)); infoTextView.setText(tmpLoc); // Setup Zoom/Hide Buttons linearLayout = (LinearLayout) findViewById(R.id.zoomview); mapView = (MapView) findViewById(R.id.mapview); mapView.invalidate(); mapView.setBuiltInZoomControls(true); //new by me mapView.setSatellite(true); // Set satellite view mZoom = (ZoomControls) mapView.getZoomControls(); linearLayout.addView(mZoom); // Setup Marker mapOverlays = mapView.getOverlays(); drawable = this.getResources().getDrawable(R.drawable.marker); itemizedOverlay = new MyItemizedOverlay(drawable); GeoPoint point = new GeoPoint(lat.intValue(), lng.intValue()); OverlayItem overlayitem = new OverlayItem(point, "", ""); itemizedOverlay.addOverlay(overlayitem); mapOverlays.add(itemizedOverlay); // Centralize Current Location myMapController = mapView.getController(); myMapController.setZoom(DEFAULT_ZOOM_NUM); centerlizeCurrentLocation(point); } Any suggest is truly appreciable.
