  • PendingIntent sent from a notication.

    - by totem
    Hi, What im trying to accomplish is to send a notification through the notification manager that once clicked will do something in the application only if its currently running. i have tried to use: notification.contentIntent = PendingIntent.getActivity(this, nNotificationCounter, Someintent, PendingIntent.FLAG_NO_CREATE) Which allways caused an exception once trying to use the notify. I switched to: Notification notification = new Notification(icon, tickerText, when); RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.some_notification); contentView.setTextViewText(R.id.title, sTitle); contentView.setTextViewText(R.id.text, sText); notification.contentView = contentView; notification.defaults |= Notification.DEFAULT_SOUND; notification.number = nNotificationCounter; Intent notificationIntent = new Intent(this, MainWindow.class).setAction(ACTION_RESET_MESSGE_COUNTER); notification.contentIntent = PendingIntent.getBroadcast(this, nNotificationCounter, notificationIntent, 0); and although this code doesn't cause an exception. it doesnt call my BroadcastReceiver which is defined as follows: public class IncomingReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(ACTION_RESET_MESSGE_COUNTER)) { System.out.println("GOT THE INTENT"); return; } } } and set in the onCreate: IntentFilter filter = new IntentFilter(ACTION_RESET_MESSGE_COUNTER); IncomingReceiver receiver = new IncomingReceiver(); context.registerReceiver(receiver, filter); Does anyone see something wrong with the code? Or how would i go about to get messages when the notification is clicked, but not create any activity if it isn't already created. edit: added the intent creation and notification creation. Thanks, Tom

  • How is a referencing environment generally implemented for closures?

    - by Alexandr Kurilin
    Let's say I have a statically/lexically scoped language with deep binding and I create a closure. The closure will consist of the statements I want executed plus the so called referencing environment, or, to quote this post, the collection of variables which can be used. What does this referencing environment actually look like implementation-wise? I was recently reading about ObjectiveC's implementation of blocks, and the author suggests that behind the scenes you get a copy of all of the variables on the stack and also of all the references to heap objects. The explanation claims that you get a "snapshot" of the referencing environment at the point in time of the closure's creation. Is that more or less what happens, or did I misread that? Is anything done to "freeze" a separate copy of the heap objects, or is it safe to assume that if they get modified between closure creation and the closure executing, the closure will no longer be operating on the original version of the object? If indeed there's copying being made, are there memory usage considerations in situations where one might want to create plenty of closures and store them somewhere? I think that misunderstanding of some of these concepts might lead to tricky issues like the ones Eric Lippert mentions in this blog post. It's interesting because you'd think that it wouldn't make sense to keep a reference to a value type that might be gone by the time the closure is called, but I'm guessing that in C# the compiler will figure out that the variable is needed later and put it into the heap instead. It seems that in most memory-managed languages everything is a reference and thus ObjectiveC is a somewhat unique situation with having to deal with copying what's on the stack.

  • Does a Postgresql dump create sequences that start with - or after - the last key?

    - by bennylope
    I recently created a SQL dump of a database behind a Django project, and after cleaning the SQL up a little bit was able to restore the DB and all of the data. The problem was the sequences were all mucked up. I tried adding a new user and generated the Python error IntegrityError: duplicate key violates unique constraint. Naturally I figured my SQL dump didn't restart the sequence. But it did: DROP SEQUENCE "auth_user_id_seq" CASCADE; CREATE SEQUENCE "auth_user_id_seq" INCREMENT 1 START 446 MAXVALUE 9223372036854775807 MINVALUE 1 CACHE 1; ALTER TABLE "auth_user_id_seq" OWNER TO "db_user"; I figured out that a repeated attempt at creating a user (or any new row in any table with existing data and such a sequence) allowed for successful object/row creation. That solved the pressing problem. But given that the last user ID in that table was 446 - the same start value in the sequence creation above - it looks like Postgresql was simply trying to start creating rows with that key. Does the SQL dump provide the wrong start key by 1? Or should I invoke some other command to start sequences after the given start ID? Keenly curious.

  • Can an interface define the signature of a c#-class

    - by happyclicker
    I have a .net-app that provides a mechanism to extend the app with plugins. Each plugin must implement a plugin-interface and must provide furthermore a constructor that receives one parameter (a resource context). During the instantiation of the plugin-class I look via reflection, if the needed constructor exists and if yes, I instantiate the class (via Reflection). If the constructor does not exists, I throw an exception that says that the plugin not could be created, because the desired constructor is not available. My question is, if there is a way to declare the signature of a constructor in the plugin-interface so that everyone that implements the plugin-interface must also provide a constructor with the desired signature. This would ease the creation of plugins. I don’t think that such a possibility exists because I think such a feature falls not in the main purpose for what interfaces were designed for but perhaps someone knows a statement that does this, something like: public interface IPlugin { ctor(IResourceContext resourceContext); int AnotherPluginFunction(); } I want to add that I don't want to change the constructor to be parameterless and then set the resource-context through a property, because this will make the creation of plugins much more complicated. The persons that write plugins are not persons with deep programming experience. The plugins are used to calculate statistical data that will be visualized by the app.

  • What are these stray zero-byte files extracted from tarball? (OSX)

    - by Scott M
    I'm extracting a folder from a tarball, and I see these zero-byte files showing up in the result (where they are not in the source.) Setup (all on OS X): On machine one, I have a directory /My/Stuff/Goes/Here/ containing several hundred files. I build it like this tar -cZf mystuff.tgz /My/Stuff/Goes/Here/ On machine two, I scp the tgz file to my local directory, then unpack it. tar -xZf mystuff.tgz It creates ~scott/My/Stuff/Goes/, but then under Goes, I see two files: Here/ - a directory, Here.bGd - a zero byte file. The "Here.bGd" zero-byte file has a random 3-character suffix, mixed upper and lower-case characters. It has the same name as the lowest-level directory mentioned in the tar-creation command. It only appears at the lowest level directory named. Anybody know where these come from, and how I can adjust my tar creation to get rid of them? Update: I checked the table of contents on the files using tar tZvf: toc does not list the zero-byte files, so I'm leaning toward the suggestion that the uncompress machine is at fault. OS X is version 10.5.5 on the unzip machine (not sure how to check the filesystem type). Tar is GNU tar 1.15.1, and it came with the machine.

  • StoreFilterField input doesn't react

    - by user1289877
    I'm trying to build grid with build in column filtering (using sencha gxt), here is my code: public Grid<Stock> createGrid() { // Columns definition ColumnConfig<Stock, String> nameCol = new ColumnConfig<Stock, String>(props.name(), 100, "Company"); // Column model definition and creation List<ColumnConfig<Stock, ?>> cl = new ArrayList<ColumnConfig<Stock, ?>>(); cl.add(nameCol); ColumnModel<Stock> cm = new ColumnModel<Stock>(cl); // Data populating ListStore<Stock> store = new ListStore<Stock>(props.key()); store.addAll(TestData.getStocks()); // Grid creation with data final Grid<Stock> grid = new Grid<Stock>(store, cm); grid.getView().setAutoExpandColumn(nameCol); grid.setBorders(false); grid.getView().setStripeRows(true); grid.getView().setColumnLines(true); // Filters definition StoreFilterField<Stock> filter = new StoreFilterField<Stock>() { @Override protected boolean doSelect(Store<Stock> store, Stock parent, Stock item, String filter) { // Window.alert(String.valueOf("a")); String name = item.getName(); name = name.toLowerCase(); if (name.startsWith(filter.toLowerCase())) { return true; } return false; } }; filter.bind(store); cm.addHeaderGroup(0, 0, new HeaderGroupConfig(filter, 1, 1)); filter.focus(); return grid; } My problem is: after I run this code, I cannot write anything to filter input, I'm using test data and classes (Stock.java and StockProperties.java) from this example: http://sencha.com/examples-dev/#ExamplePlace:filtergrid I try to put allert in doSelect method to check if this function was called, but it wasn't. Any idea will be welcome. Thanks.

  • Controller actions appear to be synchronous though on different requests?

    - by Oded
    I am under the impression that the below code should work asynchronously. However, when I am looking at firebug, I see the requests fired asynchronously, but the results coming back synchronously: Controller: [HandleError] public class HomeController : Controller { public ActionResult Status() { return Content(Session["status"].ToString()); } public ActionResult CreateSite() { Session["status"] += "Starting new site creation"; Thread.Sleep(20000); // Simulate long running task Session["status"] += "<br />New site creation complete"; return Content(string.Empty); } } Javascript/jQuery: $(document).ready(function () { $.ajax({ url: '/home/CreateSite', async: true, success: function () { mynamespace.done = true; } }); setTimeout(mynamespace.getStatus, 2000); }); var mynamespace = { counter: 0, done: false, getStatus: function () { $('#console').append('.'); if (mynamespace.counter == 4) { mynamespace.counter = 0; $.ajax({ url: '/home/Status', success: function (data) { $('#console').html(data); } }); } if (!mynamespace.done) { mynamespace.counter++; setTimeout(mynamespace.getStatus, 500); } } } Addtional information: IIS 7.0 Windows 2008 R2 Server Running in a VMWare virutual machine Can anyone explain this? Shouldn't the Status action be returning practically immediately instead of waiting for CreateSite to finish? Edit: How can I get the long running process to kick off and still get status updates?

  • OpenGL Mipmapping: how does OpenGL decide on map level?

    - by Droozle
    Hi, I am having trouble implementing mipmapping in OpenGL. I am using OpenFrameworks and have modified the ofTexture class to support the creation and rendering of mipmaps. The following code is the original texture creation code from the class (slightly modified for clarity): glEnable(texData.textureTarget); glBindTexture(texData.textureTarget, (GLuint)texData.textureID); glTexSubImage2D(texData.textureTarget, 0, 0, 0, w, h, texData.glType, texData.pixelType, data); glTexParameteri(texData.textureTarget, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(texData.textureTarget, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glDisable(texData.textureTarget); This is my version with mipmap support: glEnable(texData.textureTarget); glBindTexture(texData.textureTarget, (GLuint)texData.textureID); gluBuild2DMipmaps(texData.textureTarget, texData.glTypeInternal, w, h, texData.glType, texData.pixelType, data); glTexParameteri(texData.textureTarget, GL_TEXTURE_MAG_FILTER, GL_LINEAR_MIPMAP_LINEAR); glTexParameteri(texData.textureTarget, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR); glDisable(texData.textureTarget); The code does not generate errors (gluBuild2DMipmaps returns '0') and the textures are rendered without problems. However, I do not see any difference. The scene I render consists of "flat, square tiles" at z=0. It's basically a 2D scene. I zoom in and out by using "glScale()" before drawing the tiles. When I zoom out, the pixels of the tile textures start to "dance", indicating (as far as I can tell) unfiltered texture look-up. See: http://www.youtube.com/watch?v=b_As2Np3m8A at 25s. My question is: since I do not move the camera position, but only use scaling of the whole scene, does this mean OpenGL can not decide on the appropriate mipmap level and uses the full texture size (level 0)?

  • lambda expressions in VB.NET... what am I doing wrong???

  • Sorting page flow for has_many in Rails

    - by Gareth
    I have a page flow allowing the user to choose an object ("Player") to add to a has_many :players association in another model. 1 => List existing players for object [Enter player name] 2 => List of matching players [Select player] 3 => Confirmation page [Press 'Add'] 4 => Done I want users to be able to choose "New Player" instead of selecting a player at step 2, in which case the user will go through the standard New Player process elsewhere on the site. However, after that's done, the user should return to step 3 with the new player in place. I don't know what the best way is to implement this. I don't want to duplicate the player creation code, but I don't want to dirty up the player creation code too much just for this case. I also don't want to start sticking IDs in the session if I can help it. It's fine in simple cases but if the user ever has two windows/tabs then things start behaving badly. What do you think?

  • Dynamic jQuery dialog after data append w/o reloading page. Possible?

    - by Arun
    Howdy, So I have a page with an enormous table in a CRUD interface of sorts. Each link within a span calls a jQuery UI Dialog Form which fetches it's content from another page. When the action taking place (in this case, a creation) has completed, it appends the resulting new data to the table and forces a resort of the table. This all happens within the JS and the DOM. The problem with this, is that the new table row's CRUD links don't actually trigger the dialog form creation as all the original links in spans are only scanned on document.ready and since I'm not reloading the page, the new links cannot be seen. Code is as follows: $(document).ready(function() { var $loading = $('<img src="/images/loading.gif" alt="Loading">'); $('span a').each(function() { var $dialog = $('<div></div>') .append($loading.clone()); var $link = $(this).one('click', function() { // Dialog Stuff success: function(data) { $('#studies tbody').append( '<tr>' + '<td><span><a href="./?action=update&study=' + data.study_id + '" title="Update Study">Update</a></span></td>' + '</tr>' ); fdTableSort.init(#studies); // This re-sorts the table. $(this).dialog('close'); } $link.click(function() { $dialog.dialog('open'); return false; }); return false; }); }); }); Basically, my question is if there is any way in which to trigger a jQuery re-evaluation of the pages links without forcing me to do a browser page refresh?

  • Is CDS a valid analogy for pointers? [closed]

    - by Flinkman
    So.. bear with me. I just found an analogy to c++ pointers and CDS. This clip describes CDS(Credit Default Swaps). http://www.youtube.com/watch?v=KPNdYtrlgaU#t=120s "Here we know we have an instrument of a particular financial instrument that is demonstrably dangerous, it creates long chains of risk which are vulnerable to the failure of individual trader or market partipants, in that chain and these instruments in an affect permit the creation of vicious spirals. In which the CDS price interact with the bound price, the market price and you can have a downward spiral." What my ears are telling me: "Don't create dependences that will create long chains of crashing systems." Update: Trying to clarify with something that is closer to the readers. If I change the words: instrument = construct financial = language trader = object market partipants = c structs CDS price = uptime bound price = outcome market price = ROI(return on incestment) The quote become more understandable. Look: "Here we know we have construct of a particular language construct that is demonstrably dangerous, it creates long chains of risk which are vulnerable to the failure of individual object or structs in that chain and these system in an affect permit the creation of vicious spirals. In which the uptime interact with the outcome, the ROI and you can have a downward spiral."

  • Sysprep and Capture task sequence failing using MDT 2010

    - by Nic Young
    I have created a Windows Deployment Services server in Windows 2008 R2. When I originally set it up I was able to successfully use MDT 2010 to create my boot images as well as creating task sequences that would sysprep and capture, and deploy my custom .wim files. Everything was working perfectly. About a month later I boot up my Windows 7 x86 image and run Windows updates to keep my image up to date. I then go and run my sysprep and capture task sequence and I get the following errors: I searched online for the cause of this error message and it just seems to be a generic permission denied type of error message. I then decided to completely rebuild my VM image from scratch and try again. I am still getting the same error messages as before. The following is what I have tried troubleshooting this issue: Troubleshooting: I have ensured that that UAC and the firewall is turned completely off when trying to capture the image. I have tried recreating the task sequence and making sure that the deployment share is updated. I have ensured that the local Administrator account is enabled and has the same password as specified in the task sequence. I have tried joining the computer to the domain and running the task sequence and I get a different error: I have attempted to run the script from the command prompt with "Run as Administrator" and I still receive the same errors above. For testing purposes I have ensured that Everyone has read/write access to my deployment share. I have spent days on trying to resolve this to no avail. Any ideas?

  • Android - HorizontalScrollView within ScrollView Touch Handling

    - by Joel
    Hi, I have a ScrollView that surrounds my entire layout so that the entire screen is scrollable. The first element I have in this ScrollView is a HorizontalScrollView block that has features that can be scrolled through horizontally. I've added an ontouchlistener to the horizontalscrollview to handle touch events and force the view to "snap" to the closest image on the ACTION_UP event. So the effect I'm going for is like the stock android homescreen where you can scroll from one to the other and it snaps to one screen when you lift your finger. This all works great except for one problem: I need to swipe left to right almost perfectly horizontally for an ACTION_UP to ever register. If I swipe vertically in the very least (which I think many people tend to do on their phones when swiping side to side), I will receive an ACTION_CANCEL instead of an ACTION_UP. My theory is that this is because the horizontalscrollview is within a scrollview, and the scrollview is hijacking the vertical touch to allow for vertical scrolling. How can I disable the touch events for the scrollview from just within my horizontal scrollview, but still allow for normal vertical scrolling elsewhere in the scrollview? Here's a sample of my code: public class HomeFeatureLayout extends HorizontalScrollView { private ArrayList<ListItem> items = null; private GestureDetector gestureDetector; View.OnTouchListener gestureListener; private static final int SWIPE_MIN_DISTANCE = 5; private static final int SWIPE_THRESHOLD_VELOCITY = 300; private int activeFeature = 0; public HomeFeatureLayout(Context context, ArrayList<ListItem> items){ super(context); setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); setFadingEdgeLength(0); this.setHorizontalScrollBarEnabled(false); this.setVerticalScrollBarEnabled(false); LinearLayout internalWrapper = new LinearLayout(context); internalWrapper.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); internalWrapper.setOrientation(LinearLayout.HORIZONTAL); addView(internalWrapper); this.items = items; for(int i = 0; i< items.size();i++){ LinearLayout featureLayout = (LinearLayout) View.inflate(this.getContext(),R.layout.homefeature,null); TextView header = (TextView) featureLayout.findViewById(R.id.featureheader); ImageView image = (ImageView) featureLayout.findViewById(R.id.featureimage); TextView title = (TextView) featureLayout.findViewById(R.id.featuretitle); title.setTag(items.get(i).GetLinkURL()); TextView date = (TextView) featureLayout.findViewById(R.id.featuredate); header.setText("FEATURED"); Image cachedImage = new Image(this.getContext(), items.get(i).GetImageURL()); image.setImageDrawable(cachedImage.getImage()); title.setText(items.get(i).GetTitle()); date.setText(items.get(i).GetDate()); internalWrapper.addView(featureLayout); } gestureDetector = new GestureDetector(new MyGestureDetector()); setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (gestureDetector.onTouchEvent(event)) { return true; } else if(event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL ){ int scrollX = getScrollX(); int featureWidth = getMeasuredWidth(); activeFeature = ((scrollX + (featureWidth/2))/featureWidth); int scrollTo = activeFeature*featureWidth; smoothScrollTo(scrollTo, 0); return true; } else{ return false; } } }); } class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { //right to left if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { activeFeature = (activeFeature < (items.size() - 1))? activeFeature + 1:items.size() -1; smoothScrollTo(activeFeature*getMeasuredWidth(), 0); return true; } //left to right else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { activeFeature = (activeFeature > 0)? activeFeature - 1:0; smoothScrollTo(activeFeature*getMeasuredWidth(), 0); return true; } } catch (Exception e) { // nothing } return false; } } }

  • iPhone - UIImage Leak, CGBitmapContextCreateImage Leak

    - by bbullis21
    Alright I am having a world of difficulty tracking down this memory leak. When running this script I do not see any memory leaking, but my objectalloc is climbing. Instruments points to CGBitmapContextCreateImage create_bitmap_data_provider malloc, this takes up 60% of my objectalloc. This code is called several times with a NSTimer. //GET IMAGE FROM RESOURCE DIR NSString * fileLocation = [[NSBundle mainBundle] pathForResource:imgMain ofType:@"jpg"]; NSData * imageData = [NSData dataWithContentsOfFile:fileLocation]; UIImage * blurMe = [UIImage imageWithData:imageData]; NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; UIImage * scaledImage = [blurMe _imageScaledToSize:CGSizeMake(blurMe.size.width / dblBlurLevel, blurMe.size.width / dblBlurLevel) interpolationQuality:3.0]; UIImage * labelImage = [scaledImage _imageScaledToSize:blurMe.size interpolationQuality:3.0]; UIImage * imageCopy = [[UIImage alloc] initWithCGImage:labelImage.CGImage]; [pool drain]; // deallocates scaledImage and labelImage imgView.image = imageCopy; [imageCopy release]; Below is the blur function. I believe the objectalloc issue is located in here. Maybe I just need a pair of fresh eyes. Would be great if someone could figure this out. Sorry it is kind of long... I'll try and shorten it. @implementation UIImage(Blur) - (UIImage *)blurredCopy:(int)pixelRadius { //VARS unsigned char *srcData, *destData, *finalData; CGContextRef context = NULL; CGColorSpaceRef colorSpace; void * bitmapData; int bitmapByteCount; int bitmapBytesPerRow; //IMAGE SIZE size_t pixelsWide = CGImageGetWidth(self.CGImage); size_t pixelsHigh = CGImageGetHeight(self.CGImage); bitmapBytesPerRow = (pixelsWide * 4); bitmapByteCount = (bitmapBytesPerRow * pixelsHigh); colorSpace = CGColorSpaceCreateDeviceRGB(); if (colorSpace == NULL) { return NULL; } bitmapData = malloc( bitmapByteCount ); if (bitmapData == NULL) { CGColorSpaceRelease( colorSpace ); } context = CGBitmapContextCreate (bitmapData, pixelsWide, pixelsHigh, 8, bitmapBytesPerRow, colorSpace, kCGImageAlphaPremultipliedFirst ); if (context == NULL) { free (bitmapData); } CGColorSpaceRelease( colorSpace ); free (bitmapData); if (context == NULL) { return NULL; } //PREPARE BLUR size_t width = CGBitmapContextGetWidth(context); size_t height = CGBitmapContextGetHeight(context); size_t bpr = CGBitmapContextGetBytesPerRow(context); size_t bpp = (CGBitmapContextGetBitsPerPixel(context) / 8); CGRect rect = {{0,0},{width,height}}; CGContextDrawImage(context, rect, self.CGImage); // Now we can get a pointer to the image data associated with the bitmap // context. srcData = (unsigned char *)CGBitmapContextGetData (context); if (srcData != NULL) { size_t dataSize = bpr * height; finalData = malloc(dataSize); destData = malloc(dataSize); memcpy(finalData, srcData, dataSize); memcpy(destData, srcData, dataSize); int sums[5]; int i, x, y, k; int gauss_sum=0; int radius = pixelRadius * 2 + 1; int *gauss_fact = malloc(radius * sizeof(int)); for (i = 0; i < pixelRadius; i++) { .....blah blah blah... THIS IS JUST LONG CODE THE CREATES INT FIGURES ........blah blah blah...... } if (gauss_fact) { free(gauss_fact); } } size_t bitmapByteCount2 = bpr * height; //CREATE DATA PROVIDER CGDataProviderRef dataProvider = CGDataProviderCreateWithData(NULL, srcData, bitmapByteCount2, NULL); //CREATE IMAGE CGImageRef cgImage = CGImageCreate( width, height, CGBitmapContextGetBitsPerComponent(context), CGBitmapContextGetBitsPerPixel(context), CGBitmapContextGetBytesPerRow(context), CGBitmapContextGetColorSpace(context), CGBitmapContextGetBitmapInfo(context), dataProvider, NULL, true, kCGRenderingIntentDefault ); //RELEASE INFORMATION CGDataProviderRelease(dataProvider); CGContextRelease(context); if (destData) { free(destData); } if (finalData) { free(finalData); } if (srcData) { free(srcData); } UIImage *retUIImage = [UIImage imageWithCGImage:cgImage]; CGImageRelease(cgImage); return retUIImage; } The only thing I can think of that is holding up the objectalloc is this UIImage *retUIImage = [UIImage imageWithCGImage:cgImage];...but how to do I release that after it has been returned? Hopefully someone can help please.

  • Upgrading Windows 8 boot to VHD to Windows 8.1&ndash;Step by step guide

    - by Liam Westley
    Originally posted on: http://geekswithblogs.net/twickers/archive/2013/10/19/upgrading-windows-8-boot-to-vhd-to-windows-8.1ndashstep-by.aspxBoot to VHD – dual booting Windows 7 and Windows 8 became easy When Windows 8 arrived, quite a few people decided that they would still dual boot their machines, and instead of mucking about with resizing disk partitions to free up space for Windows 8 they decided to use the boot from VHD feature to create a huge hard disc image into which Windows 8 could be installed.  Scott Hanselman wrote this installation guide, while I myself used the installation guide from Ed Bott of ZD net fame. Boot to VHD is a great solution, it achieves a dual boot, can be backed up easily and had virtually no effect on the original Windows 7 partition. As a developer who has dual booted Windows operating systems for years, hacking boot.ini files, the boot to VHD was a much easier solution. Upgrade to Windows 8.1 – ah, you can’t do that on a virtual disk installation (boot to VHD) Last week the final version of Windows 8.1 arrived, and I went into the Windows Store to upgrade.  Luckily I’m on a fast download service, and use an SSD, because once the upgrade was downloaded and prepared Windows informed that This PC can’t run Windows 8.1, and provided the reason, You can’t install Windows on a virtual drive.  You can see an image of the message and discussion that sparked my search for a solution in this Microsoft Technet forum post. I was determined not to have to resize partitions yet again and fiddle with VHD to disk utilities and back again, and in the end I did succeed in upgrading to a Windows 8.1 boot to VHD partition.  It takes quite a bit of effort though … tldr; Simple steps of how you upgrade Boot into Windows 7 – make a copy of your Windows 8 VHD, to become Windows 8.1 Enable Hyper-V in your Windows 8 (the original boot to VHD partition) Create a new virtual machine, attaching the copy of your Windows 8 VHD Start the virtual machine, upgrade it via the Windows Store to Windows 8.1 Shutdown the virtual machine Boot into Windows 7 – use the bcedit tool to create a new Windows 8.1 boot to VHD option (pointing at the copy) Boot into the new Windows 8.1 option Reactivate Windows 8.1 (it will have become deactivated by running under Hyper-V) Remove the original Windows 8 VHD, and in Windows 7 use bcedit to remove it from the boot menu Things you’ll need A system that can run Hyper-V under Windows 8 (Intel i5, i7 class CPU) Enough space to have your original Windows 8 boot to VHD and a copy at the same time An ISO or DVD for Windows 8 to create a bootable Windows 8 partition Step by step guide Boot to your base o/s, the real one, Windows 7. Make a copy of the Windows 8 VHD file that you use to boot Windows 8 (via boot from VHD) – I copied it from a folder on C: called VHD-Win8 to VHD-Win8.1 on my N: drive. Reboot your system into Windows 8, and enable Hyper-V if not already present (this may require reboot) Use the Hyper-V manager , create a new Hyper-V machine, using half your system memory, and use the option to attach an existing VHD on the main IDE controller – this will be the new copy you made in Step 2. Start the virtual machine, use Connect to view it, and you’ll probably discover it cannot boot as there is no boot record If this is the case, go to Hyper-V manager, edit the Settings for the virtual machine to attach an ISO of a Windows 8 DVD to the second IDE controller. Start the virtual machine, use Connect to view it, and it should now attempt a fresh installation of Windows 8.  You should select Advanced Options and choose Repair - this will make VHD bootable When the setup reboots your virtual machine, turn off the virtual machine, and remove the ISO of the Windows 8 DVD from the virtual machine settings. Start virtual machine, use Connect to view it.  You will see the devices to be re-discovered (including your quad CPU becoming single CPU).  Eventually you should see the Windows Login screen. You may notice that your desktop background (Win+D) will have turned black as your Windows installation has become deactivate due to the hardware changes between your real PC and Hyper-V. Fortunately becoming deactivated, does not stop you using the Windows Store, where you can select the update to Windows 8.1. You can now watch the progress joy of the Windows 8 update; downloading, preparing to update, checking compatibility, gathering info, preparing to restart, and finally, confirm restart - remember that you are restarting your virtual machine sitting on the copy of the VHD, not the Windows 8 boot to VHD you are currently using to run Hyper-V (confused yet?) After the reboot you get the real upgrade messages; setting up x%, xx%, (quite slow) After a while, Getting ready Applying PC Settings x%, xx% (really slow) Updating your system (fast) Setting up a few more things x%, (quite slow) Getting ready, again Accept license terms Express settings Confirmed previous password Next, I had to set up a Microsoft account – which is possibly now required, and not optional Using the Microsoft account required a 2 factor authorization, via text message, a 7 digit code for me Finalising settings Blank screen, HI .. We're setting up things for you (similar to original Windows 8 install) 'You can get new apps from the Store', below which is ’Installing your apps’ - I had Windows Media Center which is counts as an app from the Store ‘Taking care of a few things’, below which is ‘Installing your apps’ ‘Taking care of a few things’, below ‘Don't turn off your PC’ ‘Getting your apps ready’, below ‘Don't turn off your PC’ ‘Almost ready’, below ‘Don't turn off your PC’ … finally, we get the Windows 8.1 start menu, and a quick Win+D to check the desktop confirmed all the application icons I expected, pinned items on the taskbar, and one app moaning about a missing drive At this point the upgrade is complete – you can shutdown the virtual machine Reboot from the original Windows 8 and return to Windows 7 to configure booting to the Windows 8.1 copy of the VHD In an administrator command prompt do following use the bcdedit tool (from an MSDN blog about configuring VHD to boot in Windows 7) Type bcedit to list the current boot options, so you can copy the GUID (complete with brackets/braces) for the original Windows 8 boot to VHD Create a new menu option, copy of the Windows 8 option; bcdedit /copy {originalguid} /d "Windows 8.1" Point the new Windows 8.1 option to the copy of the VHD; bcdedit /set {newguid} device vhd=[D:]\Image.vhd Point the new Windows 8.1 option to the copy of the VHD; bcdedit /set {newguid} osdevice vhd=[D:]\Image.vhd Set autodetection of the HAL (may already be set); bcdedit /set {newguid} detecthal on Reboot from Windows 7 and select the new option 'Windows 8.1' on the boot menu, and you’ll have some messages to look at, as your hardware is redetected (as you are back from 1 CPU to 4 CPUs) ‘Getting devices ready, blank then %xx, with occasional blank screen, for the graphics driver, (fast-ish) Getting Ready message (fast) You will have to suffer one final reboots, choose 'Windows 8.1' and you can now login to a lovely Windows 8.1 start screen running on non virtualized hardware via boot to VHD After checking everything is running fine, you can now choose to Activate Windows, which for me was a toll free phone call to the automated system where you type in lots of numbers to be given a whole bunch of new activation codes. Once you’re happy with your new Windows 8.1 boot to VHD, and no longer need the Windows 8 boot to VHD, feel free to delete the old one.  I do believe once you upgrade, you are no longer licensed to use it anyway. There, that was simple wasn’t it? Looking at the huge list of steps it took to perform this upgrade, you may wonder whether I think this is worth it.  Well, I think it is worth booting to VHD.  It makes backups a snap (go to Windows 7, copy the VHD, you backed up the o/s) and helps with disk management – want to move the o/s, you can move the VHD and repoint the boot menu to the new location. The downside is that Microsoft has complete neglected to support boot to VHD as an upgradable option.  Quite a poor decision in my opinion, and if you read twitter and the forums quite a few people agree with that view.  It’s a shame this got missed in the work on creating the upgrade packages for Windows 8.1.

  • WPF: how to find an element in a datatemplate from an itemscontrol

    - by EV
    Hi, I have the following problem: the application is using the custom itemscontrol called ToolBox. The elements of a toolbox are called toolboxitems and are custom contentcontrol. Now, the toolbox stores a number of images that are retrieved from a database and displayed. For that I use a datatemplate inside the toolbox control. However, when I try to drag and drop the elements, I don't get the image object but the database component. I thought that I should then traverse the structure to find the Image element. here's the code: Toolbox: public class Toolbox : ItemsControl { private Size defaultItemSize = new Size(65, 65); public Size DefaultItemSize { get { return this.defaultItemSize; } set { this.defaultItemSize = value; } } protected override DependencyObject GetContainerForItemOverride() { return new ToolboxItem(); } protected override bool IsItemItsOwnContainerOverride(object item) { return (item is ToolboxItem); } } ToolBoxItem: public class ToolboxItem : ContentControl { private Point? dragStartPoint = null; static ToolboxItem() { FrameworkElement.DefaultStyleKeyProperty.OverrideMetadata(typeof(ToolboxItem), new FrameworkPropertyMetadata(typeof(ToolboxItem))); } protected override void OnPreviewMouseDown(MouseButtonEventArgs e) { base.OnPreviewMouseDown(e); this.dragStartPoint = new Point?(e.GetPosition(this)); } public String url { get; private set; } protected override void OnMouseMove(MouseEventArgs e) { base.OnMouseMove(e); if (e.LeftButton != MouseButtonState.Pressed) { this.dragStartPoint = null; } if (this.dragStartPoint.HasValue) { Point position = e.GetPosition(this); if ((SystemParameters.MinimumHorizontalDragDistance <= Math.Abs((double)(position.X - this.dragStartPoint.Value.X))) || (SystemParameters.MinimumVerticalDragDistance <= Math.Abs((double)(position.Y - this.dragStartPoint.Value.Y)))) { string xamlString = XamlWriter.Save(this.Content); MessageBoxResult result = MessageBox.Show(xamlString); DataObject dataObject = new DataObject("DESIGNER_ITEM", xamlString); if (dataObject != null) { DragDrop.DoDragDrop(this, dataObject, DragDropEffects.Copy); } } e.Handled = true; } } private childItem FindVisualChild<childItem>(DependencyObject obj) where childItem : DependencyObject { for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++) { DependencyObject child = VisualTreeHelper.GetChild(obj, i); if (child != null && child is childItem) return (childItem)child; else { childItem childOfChild = FindVisualChild<childItem>(child); if (childOfChild != null) return childOfChild; } } return null; } } here is the xaml file for ToolBox and toolbox item: <Style TargetType="{x:Type s:ToolboxItem}"> <Setter Property="Control.Padding" Value="5" /> <Setter Property="ContentControl.HorizontalContentAlignment" Value="Stretch" /> <Setter Property="ContentControl.VerticalContentAlignment" Value="Stretch" /> <Setter Property="ToolTip" Value="{Binding ToolTip}" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type s:ToolboxItem}"> <Grid> <Rectangle Name="Border" StrokeThickness="1" StrokeDashArray="2" Fill="Transparent" SnapsToDevicePixels="true" /> <ContentPresenter Content="{TemplateBinding ContentControl.Content}" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" ContentTemplate="{TemplateBinding ContentTemplate}"/> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter TargetName="Border" Property="Stroke" Value="Gray" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style TargetType="{x:Type s:Toolbox}"> <Setter Property="SnapsToDevicePixels" Value="true" /> <Setter Property="Focusable" Value="False" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate> <Border BorderThickness="{TemplateBinding Border.BorderThickness}" Padding="{TemplateBinding Control.Padding}" BorderBrush="{TemplateBinding Border.BorderBrush}" Background="{TemplateBinding Panel.Background}" SnapsToDevicePixels="True"> <ScrollViewer VerticalScrollBarVisibility="Auto"> <ItemsPresenter SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </ScrollViewer> </Border> </ControlTemplate> </Setter.Value> </Setter> <Setter Property="ItemsPanel"> <Setter.Value> <ItemsPanelTemplate> <WrapPanel Margin="0,5,0,5" ItemHeight="{Binding Path=DefaultItemSize.Height, RelativeSource={RelativeSource AncestorType=s:Toolbox}}" ItemWidth="{Binding Path=DefaultItemSize.Width, RelativeSource={RelativeSource AncestorType=s:Toolbox}}" /> </ItemsPanelTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> Example usage: <Toolbox x:Name="NewLibrary" DefaultItemSize="55,55" ItemsSource="{Binding}" > <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel> <Image Source="{Binding Path=url}" /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </Toolbox> The object that I get is a database object. When using a static resource I get the Image object. How to retrieve this Image object from a datatemplate? I though that I could use this tutorial: http://msdn.microsoft.com/en-us/library/bb613579.aspx But it does not seem to solve the problem. Could anyone suggest a solution? Thanks!

  • Code excavations, wishful invocations, perimeters and domain specific unit test frameworks

    - by RoyOsherove
    One of the talks I did at QCON London was about a subject that I’ve come across fairly recently , when I was building SilverUnit – a “pure” unit test framework for silverlight objects that depend on the silverlight runtime to run. It is the concept of “cogs in the machine” – when your piece of code needs to run inside a host framework or runtime that you have little or no control over for testability related matters. Examples of such cogs and machines can be: your custom control running inside silverlight runtime in the browser your plug-in running inside an IDE your activity running inside a windows workflow your code running inside a java EE bean your code inheriting from a COM+ (enterprise services) component etc.. Not all of these are necessarily testability problems. The main testability problem usually comes when your code actually inherits form something inside the system. For example. one of the biggest problems with testing objects like silverlight controls is the way they depend on the silverlight runtime – they don’t implement some silverlight interface, they don’t just call external static methods against the framework runtime that surrounds them – they actually inherit parts of the framework: they all inherit (in this case) from the silverlight DependencyObject Wrapping it up? An inheritance dependency is uniquely challenging to bring under test, because “classic” methods such as wrapping the object under test with a framework wrapper will not work, and the only way to do manually is to create parallel testable objects that get delegated with all the possible actions from the dependencies.    In silverlight’s case, that would mean creating your own custom logic class that would be called directly from controls that inherit from silverlight, and would be tested independently of these controls. The pro side is that you get the benefit of understanding the “contract” and the “roles” your system plays against your logic, but unfortunately, more often than not, it can be very tedious to create, and may sometimes feel unnecessary or like code duplication. About perimeters A perimeter is that invisible line that your draw around your pieces of logic during a test, that separate the code under test from any dependencies that it uses. Most of the time, a test perimeter around an object will be the list of seams (dependencies that can be replaced such as interfaces, virtual methods etc.) that are actually replaced for that test or for all the tests. Role based perimeters In the case of creating a wrapper around an object – one really creates a “role based” perimeter around the logic that is being tested – that wrapper takes on roles that are required by the code under test, and also communicates with the host system to implement those roles and provide any inputs to the logic under test. in the image below – we have the code we want to test represented as a star. No perimeter is drawn yet (we haven’t wrapped it up in anything yet). in the image below is what happens when you wrap your logic with a role based wrapper – you get a role based perimeter anywhere your code interacts with the system: There’s another way to bring that code under test – using isolation frameworks like typemock, rhino mocks and MOQ (but if your code inherits from the system, Typemock might be the only way to isolate the code from the system interaction.   Ad-Hoc Isolation perimeters the image below shows what I call ad-hoc perimeter that might be vastly different between different tests: This perimeter’s surface is much smaller, because for that specific test, that is all the “change” that is required to the host system behavior.   The third way of isolating the code from the host system is the main “meat” of this post: Subterranean perimeters Subterranean perimeters are Deep rooted perimeters  - “always on” seams that that can lie very deep in the heart of the host system where they are fully invisible even to the test itself, not just to the code under test. Because they lie deep inside a system you can’t control, the only way I’ve found to control them is with runtime (not compile time) interception of method calls on the system. One way to get such abilities is by using Aspect oriented frameworks – for example, in SilverUnit, I’ve used the CThru AOP framework based on Typemock hooks and CLR profilers to intercept such system level method calls and effectively turn them into seams that lie deep down at the heart of the silverlight runtime. the image below depicts an example of what such a perimeter could look like: As you can see, the actual seams can be very far away form the actual code under test, and as you’ll discover, that’s actually a very good thing. Here is only a partial list of examples of such deep rooted seams : disabling the constructor of a base class five levels below the code under test (this.base.base.base.base) faking static methods of a type that’s being called several levels down the stack: method x() calls y() calls z() calls SomeType.StaticMethod()  Replacing an async mechanism with a synchronous one (replacing all timers with your own timer behavior that always Ticks immediately upon calls to “start()” on the same caller thread for example) Replacing event mechanisms with your own event mechanism (to allow “firing” system events) Changing the way the system saves information with your own saving behavior (in silverunit, I replaced all Dependency Property set and get with calls to an in memory value store instead of using the one built into silverlight which threw exceptions without a browser) several questions could jump in: How do you know what to fake? (how do you discover the perimeter?) How do you fake it? Wouldn’t this be problematic  - to fake something you don’t own? it might change in the future How do you discover the perimeter to fake? To discover a perimeter all you have to do is start with a wishful invocation. a wishful invocation is the act of trying to invoke a method (or even just create an instance ) of an object using “regular” test code. You invoke the thing that you’d like to do in a real unit test, to see what happens: Can I even create an instance of this object without getting an exception? Can I invoke this method on that instance without getting an exception? Can I verify that some call into the system happened? You make the invocation, get an exception (because there is a dependency) and look at the stack trace. choose a location in the stack trace and disable it. Then try the invocation again. if you don’t get an exception the perimeter is good for that invocation, so you can move to trying out other methods on that object. in a future post I will show the process using CThru, and how you end up with something close to a domain specific test framework after you’re done creating the perimeter you need.

  • New Validation Attributes in ASP.NET MVC 3 Future

    - by imran_ku07
         Introduction:             Validating user inputs is an very important step in collecting information from users because it helps you to prevent errors during processing data. Incomplete or improperly formatted user inputs will create lot of problems for your application. Fortunately, ASP.NET MVC 3 makes it very easy to validate most common input validations. ASP.NET MVC 3 includes Required, StringLength, Range, RegularExpression, Compare and Remote validation attributes for common input validation scenarios. These validation attributes validates most of your user inputs but still validation for Email, File Extension, Credit Card, URL, etc are missing. Fortunately, some of these validation attributes are available in ASP.NET MVC 3 Future. In this article, I will show you how to leverage Email, Url, CreditCard and FileExtensions validation attributes(which are available in ASP.NET MVC 3 Future) in ASP.NET MVC 3 application.       Description:             First of all you need to download ASP.NET MVC 3 RTM Source Code from here. Then extract all files in a folder. Then open MvcFutures project from mvc3-rtm-sources\mvc3\src\MvcFutures folder. Build the project. In case, if you get compile time error(s) then simply remove the reference of System.Web.WebPages and System.Web.Mvc assemblies and add the reference of System.Web.WebPages and System.Web.Mvc 3 assemblies again but from the .NET tab and then build the project again, it will create a Microsoft.Web.Mvc assembly inside mvc3-rtm-sources\mvc3\src\MvcFutures\obj\Debug folder. Now we can use Microsoft.Web.Mvc assembly inside our application.             Create a new ASP.NET MVC 3 application. For demonstration purpose, I will create a dummy model UserInformation. So create a new class file UserInformation.cs inside Model folder and add the following code,   public class UserInformation { [Required] public string Name { get; set; } [Required] [EmailAddress] public string Email { get; set; } [Required] [Url] public string Website { get; set; } [Required] [CreditCard] public string CreditCard { get; set; } [Required] [FileExtensions(Extensions = "jpg,jpeg")] public string Image { get; set; } }             Inside UserInformation class, I am using Email, Url, CreditCard and FileExtensions validation attributes which are defined in Microsoft.Web.Mvc assembly. By default FileExtensionsAttribute allows png, jpg, jpeg and gif extensions. You can override this by using Extensions property of FileExtensionsAttribute class.             Then just open(or create) HomeController.cs file and add the following code,   public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpPost] public ActionResult Index(UserInformation u) { return View(); } }             Next just open(or create) Index view for Home controller and add the following code,  @model NewValidationAttributesinASPNETMVC3Future.Model.UserInformation @{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Index</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>UserInformation</legend> <div class="editor-label"> @Html.LabelFor(model => model.Name) </div> <div class="editor-field"> @Html.EditorFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) </div> <div class="editor-label"> @Html.LabelFor(model => model.Email) </div> <div class="editor-field"> @Html.EditorFor(model => model.Email) @Html.ValidationMessageFor(model => model.Email) </div> <div class="editor-label"> @Html.LabelFor(model => model.Website) </div> <div class="editor-field"> @Html.EditorFor(model => model.Website) @Html.ValidationMessageFor(model => model.Website) </div> <div class="editor-label"> @Html.LabelFor(model => model.CreditCard) </div> <div class="editor-field"> @Html.EditorFor(model => model.CreditCard) @Html.ValidationMessageFor(model => model.CreditCard) </div> <div class="editor-label"> @Html.LabelFor(model => model.Image) </div> <div class="editor-field"> @Html.EditorFor(model => model.Image) @Html.ValidationMessageFor(model => model.Image) </div> <p> <input type="submit" value="Save" /> </p> </fieldset> } <div> @Html.ActionLink("Back to List", "Index") </div>             Now just run your application. You will find that both client side and server side validation for the above validation attributes works smoothly.                      Summary:             Email, URL, Credit Card and File Extension input validations are very common. In this article, I showed you how you can validate these input validations into your application. I explained this with an example. I am also attaching a sample application which also includes Microsoft.Web.Mvc.dll. So you can add a reference of Microsoft.Web.Mvc assembly directly instead of doing any manual work. Hope you will enjoy this article too.   SyntaxHighlighter.all()

  • force close when assign onclick to button

    - by Lynnooi
    hi, i am very new in android development as well as in java. i had developed an application that gets an image url from a site and wanted to download it into the device and later on i would like to enable users to set it as wallpapers. however, i am met a problem when assigning onclick event to a button. Once i uncomment the line in red, it will pop up a box stating that the application was stopped unexpectedly. Can someone please help me with this? private ImageView imView = null; public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); try { /* Create a URL we want to load some xml-data from. */ URL url = new URL(xmlURL); /* Get a SAXParser from the SAXPArserFactory. */ SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); /* Get the XMLReader of the SAXParser we created. */ XMLReader xr = sp.getXMLReader(); /* Create a new ContentHandler and apply it to the XML-Reader */ ExampleHandler myExampleHandler = new ExampleHandler(); xr.setContentHandler(myExampleHandler); /* Parse the xml-data from our URL. */ xr.parse(new InputSource(url.openStream())); /* Parsing has finished. */ /* Our ExampleHandler now provides the parsed data to us. */ ParsedExampleDataSet parsedExampleDataSet = myExampleHandler .getParsedData(); /* Set the result to be displayed in our GUI. */ if (myExampleHandler.filenames != null) { a = a + "\n" + myExampleHandler.filenames + ", by " + myExampleHandler.authors + "\nhits: " + myExampleHandler.hits + " downloads"; this.ed = myExampleHandler.thumbs; this.imageURL = myExampleHandler.mediafiles; } } catch (Exception e) { a = e.getMessage(); } // get thumbnail Context context = this.getBaseContext(); if (ed.length() != 0) { Drawable image = ImageOperations(context, this.ed, "image.jpg"); ImageView imgView = new ImageView(context); imgView = (ImageView) findViewById(R.id.image1); imgView.setImageDrawable(image); } TextView tv = (TextView) findViewById(R.id.txt_name); tv.setText(a); Button bt3 = (Button) findViewById(R.id.get_imagebt); //bt3.setOnClickListener(getImageBtnOnClick); } OnClickListener getImageBtnOnClick = new OnClickListener() { public void onClick(View view) { downloadFile(imageURL); } }; void downloadFile(String fileUrl) { URL myFileUrl = null; try { myFileUrl = new URL(fileUrl); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { HttpURLConnection conn = (HttpURLConnection) myFileUrl .openConnection(); conn.setDoInput(true); conn.connect(); int length = conn.getContentLength(); InputStream is = conn.getInputStream(); bmImg = BitmapFactory.decodeStream(is); // this.imView.setImageBitmap(bmImg); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } private Drawable ImageOperations(Context ctx, String url, String saveFilename) { try { InputStream is = (InputStream) this.fetch(url); Drawable d = Drawable.createFromStream(is, "src"); return d; } catch (MalformedURLException e) { e.printStackTrace(); return null; } catch (IOException e) { e.printStackTrace(); return null; } } public Object fetch(String address) throws MalformedURLException, IOException { URL url = new URL(address); Object content = url.getContent(); return content; } Main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/viewgroup"> <ImageView android:id="@+id/image1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" /> <ImageView android:id="@+id/image2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" /> <TextView android:id="@+id/txt_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" /> <Button id="@+id/get_imagebt" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="xxx Get an image" android:layout_gravity="center" /> <ImageView id="@+id/imview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" /> </LinearLayout>

  • problem in loading images from web

    - by Lynnooi
    hi, I am new in android and had developed an app which get images from the website and display it. I got it working in emulator but not in real phones. In some device, it will crash or take very long loading period. Can anyone please help me or guide me in improving it as i'm not sure whether the way i loads the images is correct or not. Here are the code i use to get the images from the web and display accordingly. if (xmlURL.length() != 0) { try { URL url = new URL(xmlURL); SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); /* Get the XMLReader of the SAXParser we created. */ XMLReader xr = sp.getXMLReader(); /* * Create a new ContentHandler and apply it to the * XML-Reader */ xr.setContentHandler(myExampleHandler); /* Parse the xml-data from our URL. */ xr.parse(new InputSource(url.openStream())); /* Parsing has finished. */ /* * Our ExampleHandler now provides the parsed data to * us. */ ParsedExampleDataSet parsedExampleDataSet = myExampleHandler.getParsedData(); } catch (Exception e) { } } if (s.equalsIgnoreCase("wallpapers")) { Context context = helloAndroid.this.getBaseContext(); for (int j = 0; j <= myExampleHandler.filenames.size() - 1; j++) { if (myExampleHandler.filenames.elementAt(j).toString() != null) { helloAndroid.this.ed = myExampleHandler.thumbs.elementAt(j) .toString(); if (helloAndroid.this.ed.length() != 0) { Drawable image = ImageOperations(context, helloAndroid.this.ed, "image.jpg"); file_info = myExampleHandler.filenames .elementAt(j).toString(); author = "\nby " + myExampleHandler.authors.elementAt(j) .toString(); switch (j + 1) { case 1: ImageView imgView1 = new ImageView(context); imgView1 = (ImageView) findViewById(R.id.image1); if (image.getIntrinsicHeight() > 0) { imgView1.setImageDrawable(image); } else imgView1 .setImageResource(R.drawable.empty_wallpaper); tv = (TextView) findViewById(R.id.filename1); tv.setText(file_info); tv = (TextView) findViewById(R.id.author1); tv.setText(author); imgView1 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(0).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 2: ImageView imgView2 = new ImageView(context); imgView2 = (ImageView) findViewById(R.id.image2); imgView2.setImageDrawable(image); tv = (TextView) findViewById(R.id.filename2); tv.setText(file_info); tv = (TextView) findViewById(R.id.author2); tv.setText(author); imgView2 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(1).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 3: //same code break; } } } } } private Drawable ImageOperations(Context ctx, String url, String saveFilename) { try { InputStream is = (InputStream) this.fetch(url); Drawable d = Drawable.createFromStream(is, "src"); return d; } catch (MalformedURLException e) { e.printStackTrace(); return null; } catch (IOException e) { e.printStackTrace(); return null; } } public Object fetch(String address) throws MalformedURLException, IOException { URL url = new URL(address); Object content = url.getContent(); return content; }

  • pagination with css

    - by bsandrabr
    Hi I've tried every combination I can think of but I can't get this to work. Can you help? I'm trying to put some css onto my pagination and have read all the examples but they all contain so many backslashes and concatenation that I just dont know how to apply it Here is my pagination code (which works fine) along with my feeble attempt at styling it if ($st > 0) { $st3=$st; print "< Previous Page "; } $f=$st+3; for($i2=$st+1;$i2<=$f;$i2++) { $i3=$i2-3; if ($i3 0) { print "$i3 "; if($i2 % 3 == 0) { print ""; } } } $g=$st+3; for($i=$st+1;$i<=$g;$i++) { print "$i "; if($i % 3 == 0) { print ""; } } $st2=$st+2; print " Next Page "; Here is the css that I took from the website /* CSS Document */ body { background: #2D2D2D; font-family:Verdana, fantasy; font-size:13px; color: white; scrollbar-base-color: black; scrollbar-arrow-color: red; scrollbar-DarkShadow-Color: black; } a:visited,a:active,a:link { color: white;text-decoration: none; } a:hover { color: red;text-decoration: overline underline;background: none; } table,tr,td { font-family:Palatino Linotype; color: #FFFFFF;font-size: 12px; } .button { font-family:Verdana, fantasy; font-size:13; color:#FFFFFF; background-color: red; } input,textarea,dropdown{ font-family:Verdana, fantasy; font-size:13; color: #FFFFFF; background-color: #000000; border: 1px solid; } textarea,.submit input{ font-family:Verdana, fantasy; font-size:13; color:#ffffff; background-color: black; } .table { background-color:#000000; } .table3 { background-color:#000000; } .table td { color: #000000; background-color:#DEDEDE; height:22px; } .table3 td { background-color:#CCCCCC; } td .alt { background-color:#EEEEEE; height:22px; } td .h { background-image:url(tablehgrad.png); background-repeat:repeat-x; font-weight: bold; background-color: #D6D6D6; } .table th { background-image:url(tablehgrad.png); background-repeat:repeat-x; color: #000000; font-weight: bold; background-color: #D6D6D6; } .menu th { font-font-size: 12px; color: silver; background-image:url(th.png); background-repeat:repeat-x; font-weight: bold; background-color: #4B4B4B; } .stats td { font-font-size: 12px; color: white; font-weight: bold; } .menu td { font-size: 12px; text-align: center; color: white; background-image:url(tdover.png); background-repeat:repeat-x; font-weight: bold; background-color: #4B4B4B; } .menu td:hover{ color: white; background-image:url(td.png); div.pagination { padding: 3px; margin: 3px; } div.pagination a { padding: 2px 5px 2px 5px; margin: 2px; border: 1px solid #AAAADD; text-decoration: none; /* no underline */ color: #000099; } div.pagination a:hover, div.pagination a:active { border: 1px solid #000099; color: #000; } div.pagination span.current { padding: 2px 5px 2px 5px; margin: 2px; border: 1px solid #000099; font-weight: bold; background-color: #000099; color: #FFF; } div.pagination span.disabled { padding: 2px 5px 2px 5px; margin: 2px; border: 1px solid #EEE; color: #DDD; } thanks
