• Generating HTML Help files based on XML documentation

  - by geekrutherford

  Since discovering the XML commenting features built into .NET years ago I have been using it to help make my code more readable and simpler for other developers to understand exactly what the code is doing. Entering /// preceding a line of code causes Visual Studio to insert "summary" tags.  It also results in additional tags being generated if you are commenting a method with parameters and a return type. I already knew that Intellisense would pick up these comments and display them when coding and selecting properties, methods, etc. from a class.  I also knew that you could set Visual Studio to generate an XML file containing said comments.  Only recently did I begin to wonder if I could generate some kind of readable help files based on these comments I so diligently added. After searching the web I came across NDoc, an open source project which creates documentation for you based on the XML files generated by Visual Studio.  Unfortunately, NDoc has become stale and no longer supported (last release was back in 2005). Fortunately there is a little known tool from Microsoft themselves called "Sandcastle Help File Builder".  This nifty little tool gives you a graphical interface that allows you to specify multiple DLL and XML files from which to generate a MSDN like HTML Help File for your own projects! You can check it out here: http://shfb.codeplex.com/ If you are curious how to set Visual Studio to generate the above reference XML documentation files simply go to your projects property page and edit as shown below (my paths are specific, you can leave yours at the default values):

• Drawing two orthogonal strings in 3d space in Android Canvas?

  - by hasanghaforian

  I want to draw two strings in canvas.First string must be rotated around Y axis,for example 45 degrees.Second string must be start at the end of first string and also it must be orthogonal to first string. This is my code: String text = "In the"; float textWidth = redPaint.measureText(text); Matrix m0 = new Matrix(); Matrix m1 = new Matrix(); Matrix m2 = new Matrix(); mCamera = new Camera(); canvas.setMatrix(null); canvas.save(); mCamera.rotateY(45); mCamera.getMatrix(m0); m0.preTranslate(-100, -100); m0.postTranslate(100, 100); canvas.setMatrix(m0); canvas.drawText(text, 100, 100, redPaint); mCamera = new Camera(); mCamera.rotateY(90); mCamera.getMatrix(m1); m1.preTranslate(-textWidth - 100, -100); m1.postTranslate(textWidth + 100, 100); m2.setConcat(m1, m0); canvas.setMatrix(m2); canvas.drawText(text, 100 + textWidth, 100, greenPaint); But in result,only first string(text with red font)is visible. How can I do drawing two orthogonal strings in 3d space?

• Sharing files with Android devices (How do I mount an HP Touchpad, Cyanogen Mod 9?)

  - by C.Werthschulte

  I've recently installed Cyanogen Mod 9 on my HP Touchpad tablet, but I'm encountering problems when trying to access it from my Ubuntu laptop (Ubuntu 11.10, Gnome-Shell, Nautilus). I've first tried accessing it via PTP as suggested here. Ubuntu will recognize the Touchpad as a digicam and only grant me access to two directories: "DCIM" and "Pictures". I then tried accessing the tablet via MTP using this post on OMGUbuntu!. Ubuntu will connect to the tablet, but only grant me access to a folder named "Playlists". I'm a bit clueless as to what I'm doing wrong and would very much appreciate any help or hints. Many thanks!

• Best strategy for supporting multiple server communication from iPhone/android app?

  - by tipycalFlow

  I'm making an app that will be used in multiple hospitals in the US. As per HIPAA compliance requirement, every hospital will have its own server that complies with these requirements of ensuring patient data security, etc. Now the task is that the app should communicate with a particular server based on the login info. An additional requirement is that new hospitals(servers) are likely to be added along the way, even after the app is available on the market. So basically, according to some login credentials, the app should communicate with the server of the hospital assigned to that person. One pretty crude way is to set up our own server which links the hospitals with the login info and accordingly, provides a base-url for data exchange. Is there a more efficient way to handle this?

• Identifying elements from data feeds generated by affiliate sites

  - by SPI

  I am working with data feeds from affiliate sites. The basic idea is to provide an interface where the user can paste a link to an XML datafeed (these are huge btw, around 60 mb) that would then be streamed, parsed into small chunks, and mined for the required data which would then be stored in the database. The problem is that different affiliate sites have different Schemas for their XML's. It is a little hard mapping the elements in an XML to your database attributes when you don't actually know which element contains what. My Solution: Use XPath to traverse through the first set of parent and it's descendent's, fetch the elements as well as the data and and ask the user to map this data to the attributes in the database by selecting from a set of radio buttons that represent the attributes from the database. This will be done just once for each new Feed, once the system know's what's what it will automatically upload the data from the XML to the database. Does this sound viable? Is there a better solution? I realize this leaves an uncomfortable opening for human error.. Thanks.

• Telerik OpenAccess ORM and the XML Metadata Source

  We all know that Telerik OpenAccess ORM has a completely new face with the Q1 2010 release so it is about time to start blogging about some of the features and improvements that the new Visual Designer brought along.  Today I will talk about one of the most notable changes in the new version of OpenAccess ORM and that is the XML only mapping. You all know that so far with the previous versions of the product the mapping information was defined by a mix of XML configuration files and CLR attributes. After a lot of customer feedback and thorough thought we decided to make the XML and the attributes as two separate and self-contained sources of metadata information about your model. You can choose one based on your personal preferences. I will start with a brief overview over the new XML mapping definition. Unlike previous versions, where all ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Android Java: Way to effectively pause system time while debugging?

  - by TheMaster42

  In my project, I call nanoTime and use that to get a deltaTime which I pass to my entities and animations. However, while debugging (for example, stepping through my code), the system time on my phone is happily chugging along, so it's impossible to look at, say, two sequential frames of data in the debugger (since by the time I'm done looking at the first frame, the system time has continued to move ahead by seconds or even minutes). Is there a programming practice or method to pause the system clock (or a way for my code to intercept and fake my deltaTime) whenever I pause execution from the debugger? Additional Information: I'm using Eclipse Classic with the ADT plugin and a Samsung SII, coding in Java. My code invoking nanoTime: http://pastebin.com/0ZciyBtN I do all display via a Canvas object (2D sprites and animations).

• Android GPS timeout

  - by Scott Saunders

  I'm writing an Android application that, among other things, needs to send the current GPS coordinates to a server when the user tells it to. From a context menu, I run the service below. The service is a LocationListener and requests updates from the LocationManager. When it gets a location (onLocationChanged()), it removes itself as a listener and sends the coordinates off to the server. All of this is working. However, if GPS coordinates are not quickly available, my service just keeps running until it gets some. It holds up the UI with a progress dialog, which is annoying. Worse, if the user has moved since starting the service, the first GPS coordinates might be wrong and the app will send bad data to the server. I need a timeout on the service. Is there a good way to do that? I'm not very experienced with threads. I think I can run a Runnable in the onStartCommand() method that will somehow count down 30 seconds and then, if there is no GPS result yet, call my service's stop() method. Does that sound like the best way to do this? Alternatively, is it possible to tell if the GPS cannot get a fix? How would I go about doing that? Edit: To further clarify, I'm looking for the best way to "give up" on getting a Location after some amount of time. public class AddCurrentLocation extends Service implements LocationListener { Application app; LocationManager mLocManager; ProgressDialog mDialog; @Override public int onStartCommand(Intent intent, int arg0, int arg1) { app = getApplication(); // show progress dialog if (app.getScreen() != null) { mDialog = ProgressDialog.show(app.getScreen(), "", "Adding Location. Please wait...", true); } // find GPS service and start listening Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); mLocManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); String bestProvider = mLocManager.getBestProvider(criteria, true); mLocManager.requestLocationUpdates(bestProvider, 2000, 0, this); return START_NOT_STICKY; } private void stop() { mLocManager.removeUpdates(this); if (mDialog != null) { mDialog.dismiss(); } stopSelf(); } @Override public void onLocationChanged(Location location) { // done with GPS stop listening mLocManager.removeUpdates(this); sendLocation(location); // method to send info to server stop(); } // other required methods and sendLocation() ... }

• Loading cross domain XML with Javascript using a hybrid iframe-proxy/xsl/jsonp concept?

  - by Josef

  On our site www.foo.com we want to download and use http://feeds.foo.com/feed.xml with Javascript. We'll obviously use Access-Control but for browsers that don't support it we are considering the following as a fallback: On www.foo.com, we set document.domain, provide a callback function and load the feed into a (hidden) iframe: document.domain = 'foo.com'; function receive_data(data) { // process data }; var proxy = document.createElement('iframe'); proxy.src = 'http://feeds.foo.com/feed.xml'; document.body.appendChild(proxy); On feeds.foo.com, add an XSL to feed.xml and use it to transform the feed into an html document that also sets document.domain and calls the callback function in its parent with the feed data as json: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="ROOT"> <html><body> <script type="text/javascript"> document.domain = 'foo.com'; parent.receive_data([<xsl:apply-templates/>]); </script> </body></html> </xsl:template> <!-- templates that transform data into json objects go here --> </xsl:stylesheet> Is there a better way to load XML from feeds.foo.com and what are the ramifications of this iframe-proxy/xslt/jsonp trick? (..and in what cases will it fail?) Remarks This does not work in Safari & Chrome but since both support Access-Control it's fine. We want little or no change to feeds.foo.com We are aware of (but not interested in) server-side proxy solutions update: wrote about it

• System.MissingMethodException for XslCompiledTransform.Transform when running application on differe

  - by Codesleuth

  I have a problem where I compiled my application on Visual Studio 2010 while targetting the .NET Framework 3.5, deployed it to a client server, only to find it gives me the following error: ************** Exception Text ************** System.MissingMethodException: Method not found: 'Void System.Xml.Xsl.XslCompiledTransform.Transform( System.Xml.XPath.IXPathNavigable, System.Xml.Xsl.XsltArgumentList, System.Xml.XmlWriter, System.Xml.XmlResolver)'. ************** Loaded Assemblies ************** [...] System.Xml Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.3082 (QFE.050727-3000) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Xml/2.0.0.0__b77a5c561934e089/System.Xml.dll The method it says it's looking for is this: XslTransform.Transform Method (IXPathNavigable, XsltArgumentList, XmlWriter, XmlResolver) (Supported in: 4, 3.5, 3.0, 2.0, 1.1) I've tried setting up a redirect to the .NET Framework 4.0 version of the same DLL using the assemblyBinding element like so: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.Xml" publicKeyToken="b77a5c561934e089" culture="neutral" /> <bindingRedirect oldVersion="2.0.0.0" newVersion="4.0.0.0"/> <codeBase version="4.0.0.0" href="file:///C:/WINDOWS/Microsoft.NET/assembly/GAC_MSIL/System.Xml/v4.0_4.0.0.0__b77a5c561934e089/System.Xml.dll" /> </dependentAssembly> </assemblyBinding> </runtime> But now the application won't run, and puts this in the event log: EventType clr20r3, P1 myapplication.exe, P2 3.85.12.27583, P3 4be9757f, P4 system.configuration, P5 2.0.0.0, P6 4889de74, P7 1a6, P8 136, P9 ioibmurhynrxkw0zxkyrvfn0boyyufow, P10 NIL.

• Android - Autocomplete with contacts

  - by The Salt

  I've created an AutoCompleteTextView box that displays the names of all contacts, but after looking in the Android APIs, it seems my method is probably quite inefficient. Currently I am grabbing a cursor of the all the contacts, placing each name and each contact id into two different arrays, then passing the name array to the AutoCompleteTextView. When a user selects an item, I lookup which ID the contact selected in the second id array created above. Code below: private ContactNames mContactData; // Fill the autocomplete textbox Cursor contactsCursor = grabContacts(); mContactData = new ContactNames(contactsCursor); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.contact_name, mContactData.namesArray); mNameText.setAdapter(adapter); private class ContactNames { private String[] namesArray; private long[] idsArray; private ContactNames(Cursor cur) { namesArray = new String[cur.getCount()]; idsArray = new long[cur.getCount()]; String name; Long contactid; // Get column id's int nameColumn = cur.getColumnIndex(People.NAME); int idColumn = cur.getColumnIndex(People._ID); int i=0; cur.moveToFirst(); // Check that there are actually any contacts returned by the cursor if (cur.getCount()>0){ do { // Get the field values name = cur.getString(nameColumn); contactid = Long.parseLong(cur.getString(idColumn)); // Do something with the values. namesArray[i] = name; idsArray[i] = contactid; i++; } while (cur.moveToNext()); } } private long search(String name){ // Lookup name in the contact list that we've put in an array int indexOfName = Arrays.binarySearch(namesArray, name); long contact = 0; if (indexOfName>=0) { contact = idsArray[indexOfName]; } return contact; } } private Cursor grabContacts(){ // Form an array specifying which columns to return. String[] projection = new String[] {People._ID, People.NAME}; // Get the base URI for the People table in the Contacts content provider. Uri contacts = People.CONTENT_URI; // Make the query. Cursor managedCursor = managedQuery(contacts, projection, null, null, People.NAME + " ASC"); // Put the results in ascending order by name startManagingCursor(managedCursor); return managedCursor; } There must be a better way of doing this - basically I'm struggling to see how I can find which item a user selected in an AutoCompleteTextView. Any ideas? Cheers.

• Android "Trying to use recycled bitmap" error?

  - by Mike

  Hi all, I am running into a problem with bitmaps on an Android application I am working on. What is suppose to happen is that the application downloads images from a website, saves them to the device, loads them into memory as bitmaps into an arraylist, and displays them to the user. This all works fine when the application is first started. However, I have added a refresh option for the user where the images are deleted, and the process outlined above starts all over. My problem: By using the refresh option the old images were still in memory and I would quickly get OutOfMemoryErrors. Thus, if the images are being refreshed, I had it run through the arraylist and recycle the old images. However, when the application goes to load the new images into the arraylist, it crashes with a "Trying to use recycled bitmap" error. As far as I understand it, recycling a bitmap destroys the bitmap and frees up its memory for other objects. If I want to use the bitmap again, it has to be reinitialized. I believe that I am doing this when the new files are loaded into the arraylist, but something is still wrong. Any help is greatly appreciated as this is very frustrating. The problem code is below. Thank you! public void fillUI(final int refresh) { // Recycle the images to avoid memory leaks if(refresh==1) { for(int x=0; x<images.size(); x++) images.get(x).recycle(); images.clear(); selImage=-1; // Reset the selected image variable } final ProgressDialog progressDialog = ProgressDialog.show(this, null, this.getString(R.string.loadingImages)); // Create the array with the image bitmaps in it new Thread(new Runnable() { public void run() { Looper.prepare(); File[] fileList = new File("/data/data/[package name]/files/").listFiles(); if(fileList!=null) { for(int x=0; x<fileList.length; x++) { try { images.add(BitmapFactory.decodeFile("/data/data/[package name]/files/" + fileList[x].getName())); } catch (OutOfMemoryError ome) { Log.i(LOG_FILE, "out of memory again :("); } } Collections.reverse(images); } fillUiHandler.sendEmptyMessage(0); } }).start(); fillUiHandler = new Handler() { public void handleMessage(Message msg) { progressDialog.dismiss(); } }; }

• Quick way to get an NSDictionary from an XML NSData representation?

  - by dontWatchMyProfile

  I've loaded an XML file as NSData into memory and parse over the elements using NSXMLParser. Although it works, it's a very ugly and hard to maintain code since there are about 150 different elements to parse. I know there are nice third-party solutions, but I want to keep it with the iPhone SDK for purpose of practice and fun. So I thought: Why not convert that XML file into an NSDictionary? Having this, I could use fast enumeration to go over the elements. Or is it just the same amount of ugly code needed to parse and process an XML right away with NSXMLParser? Would I build up an NSDictionary for every found node in the XML and create a huge one, containing the whole structure and data? Or is there an even simpler way?

• What is the purpose of both target API and minSDK

  - by Scott Ferguson

  Can somebody explain to me the difference between the project target and the minimum SDK? I want my app to run on Donut devices, and the APK I built with a target of 7 worked just fine. When I set an explicit minimum SDK in the Android manifest of 4 (1.6) the compiler bitched at me that the target exceeded the minimum. I reset the target to 4 only to see what would happen, and now I've got compiler errors. An example is the START_NOT_STICKY constant in android.app.Service. It doesn't exist in API level 4, but does exist in API level 7. This is also the case with Service.onStartCommand(). In API level 7 you need to explicity override this method, whereas in API level 4 you don't. So why does the app work in 1.6 despite all this? How could 1.6 know how to use SERVICE_NOT_STICKY when the associated API level doesn't know about it?

• Android Gallery View Update Images

  - by xger86x

  Hi, i have a question about using GalleryView. At first, i set five "default images" to show from drawable directory. But after, i want to run an Async Task in which i download the images, save them and show them in the gallery. For that i created the following Adapter: public class ImageAdapter extends BaseAdapter { int mGalleryItemBackground; private Context mContext; private ArrayList<Integer> mImageIds = new ArrayList<Integer>(); private ArrayList<Drawable> mImageDrawables = new ArrayList<Drawable>(); public ImageAdapter(Context c) { mContext = c; TypedArray a = obtainStyledAttributes(R.styleable.Gallery1); mGalleryItemBackground = a.getResourceId( R.styleable.Gallery1_android_galleryItemBackground, 0); a.recycle(); } public void setPlaces(int count) { for (int i = 0; i < count; i++) { mImageIds.add(R.drawable.tournoimg); mImageDrawables.add(null); } } public void setDrawable(String resource, int position) { Drawable image = Drawable.createFromPath(resource); mImageDrawables.add(position, image); } public int getCount() { return mImageIds.size(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { ImageView i = new ImageView(mContext); if (mImageDrawables.get(position) == null) i.setImageResource(mImageIds.get(position)); else i.setImageDrawable(mImageDrawables.get(position)); i.setLayoutParams(new Gallery.LayoutParams(60, 78)); i.setScaleType(ImageView.ScaleType.FIT_XY); i.setBackgroundResource(mGalleryItemBackground); return i; } } } and the following Async Task private class FillImages extends AsyncTask<ArrayList<Place>, Void, Void> { protected Void doInBackground(ArrayList<Place>... listplaces) { ArrayList<Place> places = listplaces[0]; Iterator<Place> it = places.iterator(); int position = 0; while (it.hasNext()) { Place p = it.next(); saveImage(p.getImage(), p.getURLImage()); // Gallery g = (Gallery) findViewById(R.id.gallery); mImageAdapter.setDrawable(p.getImage(), position); position++; mImageAdapter.notifyDataSetChanged(); } return (null); } But when i run it i have this error: Caused by: android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. Any idea? Thanks
