  • Parsing JSON into XML using Windows Phone

    - by Henry Edwards
    I have this code, but can't get it all working. I am trying to get a json string into xml. So that I can get a list of items when i parse the data. Is there a better way to parse json into xml. If so what's the best way to do it, and if possible could you give me a working example? The URL that is in the code is not the URL that i am using using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using Microsoft.Phone.Controls; using Newtonsoft.Json; using Newtonsoft.Json.Serialization; using Newtonsoft.Json.Converters; using Newtonsoft.Json.Utilities; using Newtonsoft.Json.Linq; using Newtonsoft.Json.Schema; using Newtonsoft.Json.Bson; using System.Xml; using System.Xml.Serialization; using System.Xml.Linq; using System.Xml.Linq.XDocument; using System.IO; namespace WindowsPhonePanoramaApplication3 { public partial class Page2 : PhoneApplicationPage { public Page2() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e1) { /* because the origional JSON string has multiple root's this needs to be added */ string json = "{BFBC2_GlobalStats:"; json += DownlodUrl("http://api.bfbcs.com/api/xbox360?globalstats"); json += "}"; XmlDocument doc = (XmlDocument)JsonConvert.DeserializeObject(json); textBox1.Text = GetXmlString(doc); } private string GetXmlString() { throw new NotImplementedException(); } private string DownlodUrl(string url) { string result = null; try { WebClient client = new WebClient(); result = client.DownloadString(url); } catch (Exception ex) { // handle error result = ex.Message; } return result; } private string GetXmlString(XmlDocument xmlDoc) { sw = new StringWriter(); XmlTextWriter xw = new XmlTextWriter(sw); xw.Formatting = System.Xml.Formatting.Indented; xmlDoc.WriteTo(xw); return sw.ToString(); } } } The URL outputs the following code: {"StopName":"Race Hill", "stopId":7553, "NaptanCode":"bridwja", "LongName":"Race Hill", "OperatorsCode1":" 5", "OperatorsCode2":" ", "OperatorsCode3":" ", "OperatorsCode4":"bridwja", "Departures":[ { "ServiceName":"", "Destination":"", "DepartureTimeAsString":"", "DepartureTime":"30/01/2012 00:00:00", "Notes":""}` Thanks for your responses. So Should i just leave the data a json and then view the data via that??? Is this a way to show the data from a json string. public void Load() { // form the URI UriBuilder uri = new UriBuilder("http://mysite.com/events.json"); WebClient proxy = new WebClient(); proxy.OpenReadCompleted += new OpenReadCompletedEventHandler(OnReadCompleted); proxy.OpenReadAsync(uri.Uri); } void OnReadCompleted(object sender, OpenReadCompletedEventArgs e) { if (e.Error == null) { var serializer = new DataContractJsonSerializer(typeof(EventList)); var events = (EventList)serializer.ReadObject(e.Result); foreach (var ev in events) { Items.Add(ev); } } } public ObservableCollection<EventDetails> Items { get; private set; } Edit: Have now kept the url as json and have now got it working by using the json way.

  • Single DispatcherServlet with Multiple Controllers

    - by jwmajors81
    I am trying to create some restful web services using Spring MVC 3.0. I currently have an issue that only 1 of my 2 controllers will work at any given time. As it turns out, whichever class comes first when sorted alphabetically will work properly. The error I get is: handleNoSuchRequestHandlingMethod No matching handler method found for servlet request: path '/polinq.xml', method 'GET', parameters map[[empty]] I had a very simliar message earlier also, except instead of the map being empty it was something like map[v--String(array)] Regardless of the message though, currently the LocationCovgController works and the PolicyInquiryController doesn't. If I change the change of the PolicyInquiryController to APolicyInquiryController, then it will start funcitoning properly and the LocationCovgController will stop working. Any assistance would be greatly appreciated. Thank you very much, Jeremy The information provided below includes the skeleton of both controller classes and also the servlet config file that defines how spring should be setup. Controller 1 package org.example; @Controller @RequestMapping(value = "/polinq.*") public class PolicyInquiryController { @RequestMapping(value = "/polinq.*?comClientId={comClientId}") public ModelAndView getAccountSummary( @PathVariable("comClientId") String commercialClientId) { // setup of variable as was removed. ModelAndView mav = new ModelAndView("XmlView", BindingResult.MODEL_KEY_PREFIX + "accsumm", as); return mav; } } Controller 2 package org.example; @Controller @RequestMapping(value = "/loccovginquiry.*") public class LocationCovgController { @RequestMapping(value = "/loccovginquiry.*method={method}") public ModelAndView locationCovgInquiryByPolicyNo( @PathVariable("method")String method) { ModelAndView mav = new ModelAndView("XmlView", BindingResult.MODEL_KEY_PREFIX + "loccovg", covgs); return mav; } } Servlet Config <context:component-scan base-package="org.example." /> <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver" p:order="0"> <property name="mediaTypes"> <map> <entry key="atom" value="application/atom+xml"/> <entry key="xml" value="application/xml"/> <entry key="json" value="application/json"/> <entry key="html" value="text/html"/> </map> </property> <property name="defaultContentType" value="text/html"/> <property name="ignoreAcceptHeader" value="true"/> <property name="favorPathExtension" value="true"/> <property name="viewResolvers"> <list> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> </list> </property> <property name="defaultViews"> <list> <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"/> </list> </property> </bean> <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" /> <bean id="XmlView" class="org.springframework.web.servlet.view.xml.MarshallingView"> <property name="marshaller" ref="marshaller"/> </bean> <oxm:jaxb2-marshaller id="marshaller"> <oxm:class-to-be-bound name="org.example.policy.dto.AccountSummary"/> <oxm:class-to-be-bound name="org.example.policy.dto.InsuredName"/> <oxm:class-to-be-bound name="org.example.policy.dto.Producer"/> <oxm:class-to-be-bound name="org.example.policy.dto.PropertyLocCoverage"/> <oxm:class-to-be-bound name="org.example.policy.dto.PropertyLocCoverages"/> </oxm:jaxb2-marshaller>

  • How to manage a MotionEvent going from one View to another?

    - by Darren
    I have a SurfaceView that takes up part of the screen, and some buttons along the bottom. When a button is pressed and the user drags, I want to be able to drag a picture (based on the button) onto the SurfaceView and have it drawn there. I want to be able to use clickListeners and the like, and not just have a giant SurfaceView with me writing code to detect where the user pressed and if it's a button, etc. I have somewhat of a solution, but it seems a bit of a hack to me. What is the best way to accomplish this using the framework intelligently? Part of my XML: <RelativeLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background"> <!-- Place buttons along the bottom --> <RelativeLayout android:id="@+id/bottom_bar" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="40dip" android:layout_alignParentBottom="true" android:background="@null"> <ImageButton android:id="@+id/btn_1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:background="@null" android:src="@drawable/btn_1"> </ImageButton> <!-- More buttons here... --> </RelativeLayout> <!-- Place the SurfaceView in a frame so we can stack on top of it --> <FrameLayout android:layout_width="fill_parent" android:layout_height="0px" android:layout_weight="1" android:layout_above="@id/bottom_bar"> <com.project.question.MySurfaceView android:id="@+id/my_view" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </FrameLayout> And the relevant Java code in MySurfaceView, which extends SurfaceView. mTouchX and Y are used in the onDraw method to draw the image: @Override public boolean onTouchEvent(MotionEvent event){ mTouchX = (int) event.getX(); mTouchY = (int) event.getY(); return true; } public void onButtonTouchEvent(MotionEvent event){ event.setLocation(event.getX(), event.getY() + mScreenHeight); onTouchEvent(event); } Finally, the activity: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.my_surface); mView = (MySurfaceView) findViewById(R.id.my_view); mSurfaceHeight = mView.getHeight(); mBtn = (ImageButton) findViewById(R.id.btn_1); mBtn.setOnTouchListener(mTouchListener); } OnTouchListener mTouchListener = new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { int [] location = new int[2]; v.getLocationOnScreen(location); event.setLocation(event.getX() + location[0], event.getY()); mView.onButtonTouchEvent(event); return true; } }; Strangely, one has to add to the x-coordinate in the activity, then add to the y coordinate in the View. Otherwise, it doesn't show up in the correct position. If you add nothing, something drawn using mTouchX and mTouchY will show up in the upper left corner of the SurfaceView. Any direction would be greatly appreciated. If I'm going about this completely the wrong way, that would be good information too.

  • How do I solve an unresolved external when using C++ Builder packages?

    - by David M
    I'm experimenting with reconfiguring my application to make heaving use of packages. Both I and another developer running a similar experiment are running into a bit of trouble when linking using several different packages. We're probably both doing something wrong, but goodness knows what :) The situation is this: The first package, PackageA.bpl, contains C++ class FooA. The class is declared with the PACKAGE directive. The second package, PackageB.bpl, contains a class inheriting from FooA, called FooB. It includes FooB.h, and the package is built using runtime packages, and links to PackageA by adding a reference to PackageA.bpi. When building PackageB, it compiles fine but linking fails with a number of unresolved externals, the first few of which are: [ILINK32 Error] Error: Unresolved external '__tpdsc__ FooA' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external 'FooA::' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external '__fastcall FooA::~FooA()' referenced from blah\FooB.OBJ etc. Running TDump on PackageA.bpl shows: Exports from PackageA.bpl 14 exported name(s), 14 export addresse(s). Ordinal base is 1. Sorted by Name: RVA Ord. Hint Name -------- ---- ---- ---- 00002A0C 8 0000 __tpdsc__ FooA 00002AD8 10 0001 __linkproc__ FooA::Finalize 00002AC8 9 0002 __linkproc__ FooA::Initialize 00002E4C 12 0003 __linkproc__ PackageA::Finalize 00002E3C 11 0004 __linkproc__ PackageA::Initialize 00006510 14 0007 FooA:: 00002860 5 0008 FooA::FooA(FooA&) 000027E4 4 0009 FooA::FooA() 00002770 3 000A __fastcall FooA::~FooA() 000028DC 6 000B __fastcall FooA::Method1() const 000028F4 7 000C __fastcall FooA::Method2() const 00001375 2 000D Finalize 00001368 1 000E Initialize 0000610C 13 000F ___CPPdebugHook So the class definitely seems to be exported and available to link. I can see entries for the specific things ILink32 says it's looking for and not finding. Running TDump on the BPI file shows similar entries. Other info The class does descend from TObject, though originally before refactoring into packages it was a normal C++ class. (More detail below. It seems "safer" using VCL-style classes when trying to solve problems with a very Delphi-ish thing like this anyway. Changing this only changes the order of unresolved externals to first not find Method1 and Method2, then others.) Declaration for FooA: class PACKAGE FooA: public TObject { public: FooA(); virtual __fastcall ~FooA(); FooA(const FooA&); virtual __fastcall long Method1() const; virtual __fastcall long Method2() const; }; and FooB: class FooB: public FooA { public: FooB(); virtual __fastcall ~FooB(); ... other methods... }; All methods definitely are implemented in the .cpp files, so it's not not finding them because they don't exist! The .cpp files also contain #pragma package(smart_init) near the top, under the includes. Questions that might help... Are packages reliable using C++, or are they only useable with Delphi code? Is linking to the first package by adding a reference to its BPI correct - is that how you're supposed to do it? I could use a LIB but it seems to make the second package much larger, and I suspect it's statically linking in the contents of the first. Can we use the PACKAGE directive only on TObject-derived classes? There is no compiler warning using it on standard C++ classes. Is splitting code into packages the best way to achieve the goal of isolating code and communicating through defined layers / interfaces? I've been investigating this path because it seems to be the C++Builder / Delphi Way, and if it worked it looks attractive. But are there better alternatives? I'm very new to using packages and have only known about them through using components before. Any general words of advice would be great! We're using C++Builder 2010. I've fabricated the class and method names in the above code examples, but other than that the details are exactly what we're seeing. Cheers, David

  • Servlet Filter: Socket need to be referenced in doFilter()

    - by Craig m
    Right now I have a filter that has the sockets opened in the init and for some reason when I open them in doFilter() it doesn't work with the server app right so I have no choice but to put it in the init I need to be able to reference the outSide.println("test"); in doFilter() so I can send that to my server app every time the if statement it in is is tripped. Heres my code: import java.net.*; import java.io.*; import java.util.*; import javax.servlet.*; import javax.servlet.http.*; public final class IEFilter implements Filter { public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { String browser = ""; String blockInfo; String address = request.getRemoteAddr(); if(((HttpServletRequest)request).getHeader ("User-Agent").indexOf("MSIE") >= 0) { browser = "Internet Explorer"; } if(browser.equals("Internet Explorer")) { BufferedWriter fW = new BufferedWriter(new FileWriter("C://logs//IElog.rtf")); blockInfo = "Blocked IE user from:" + address; response.setContentType("text/html"); PrintWriter out = response.getWriter(); out.println("<HTML>"); out.println("<HEAD>"); out.println("<TITLE>"); out.println("This page is not available - JNetProtect"); out.println("</TITLE>"); out.println("</HEAD>"); out.println("<BODY>"); out.println("<center><H1>Error 403</H1>"); out.println("<br>"); out.println("<br>"); out.println("<H1>Access Denied</H1>"); out.println("<br>"); out.println("Sorry, that resource may not be accessed now."); out.println("<br>"); out.println("<br>"); out.println("<hr />"); out.println("<i>Page Filtered By JNetProtect</i>"); out.println("</BODY>"); out.println("</HTML>"); //init.outSide.println("Blocked and Internet Explorer user"); fW.write(blockInfo); fW.newLine(); fW.close(); } else { chain.doFilter(request, response); } } public void destroy() { outsocket.close(); outSide.close(); } public void init(FilterConfig filterConfig) { try { ServerSocket fs; Socket outsocket; PrintWriter outSide ; outsocket = new Socket("Localhost", 1337); outSide = new PrintWriter(outsocket.getOutputStream(), true); }catch (Exception e){ System.out.println("error with this connection"); e.printStackTrace();} } }

  • Drawing a TextBox in an extended Glass Frame w/o WPF

    - by Lazlo
    I am trying to draw a TextBox on the extended glass frame of my form. I won't describe this technique, it's well-known. Here's an example for those who haven't heard of it: http://www.danielmoth.com/Blog/Vista-Glass-In-C.aspx The thing is, it is complex to draw over this glass frame. Since black is considered to be the 0-alpha color, anything black disappears. There are apparently ways of countering this problem: drawing complex GDI+ shapes are not affected by this alpha-ness. For example, this code can be used to draw a Label on glass (note: GraphicsPath is used instead of DrawString in order to get around the horrible ClearType problem): public class GlassLabel : Control { public GlassLabel() { this.BackColor = Color.Black; } protected override void OnPaint(PaintEventArgs e) { GraphicsPath font = new GraphicsPath(); font.AddString( this.Text, this.Font.FontFamily, (int)this.Font.Style, this.Font.Size, Point.Empty, StringFormat.GenericDefault); e.Graphics.SmoothingMode = SmoothingMode.HighQuality; e.Graphics.FillPath(new SolidBrush(this.ForeColor), font); } } Similarly, such an approach can be used to create a container on the glass area. Note the use of the polygons instead of the rectangle - when using the rectangle, its black parts are considered as alpha. public class GlassPanel : Panel { public GlassPanel() { this.BackColor = Color.Black; } protected override void OnPaint(PaintEventArgs e) { Point[] area = new Point[] { new Point(0, 1), new Point(1, 0), new Point(this.Width - 2, 0), new Point(this.Width - 1, 1), new Point(this.Width -1, this.Height - 2), new Point(this.Width -2, this.Height-1), new Point(1, this.Height -1), new Point(0, this.Height - 2) }; Point[] inArea = new Point[] { new Point(1, 1), new Point(this.Width - 1, 1), new Point(this.Width - 1, this.Height - 1), new Point(this.Width - 1, this.Height - 1), new Point(1, this.Height - 1) }; e.Graphics.FillPolygon(new SolidBrush(Color.FromArgb(240, 240, 240)), inArea); e.Graphics.DrawPolygon(new Pen(Color.FromArgb(55, 0, 0, 0)), area); base.OnPaint(e); } } Now my problem is: How can I draw a TextBox? After lots of Googling, I came up with the following solutions: Subclassing the TextBox's OnPaint method. This is possible, although I could not get it to work properly. It should involve painting some magic things I don't know how to do yet. Making my own custom TextBox, perhaps on a TextBoxBase. If anyone has good, valid and working examples, and thinks this could be a good overall solution, please tell me. Using BufferedPaintSetAlpha. (http://msdn.microsoft.com/en-us/library/ms649805.aspx). The downsides of this method may be that the corners of the textbox might look odd, but I can live with that. If anyone knows how to implement that method properly from a Graphics object, please tell me. I personally don't, but this seems the best solution so far. To be honest, I found a great C++ article, but I am way too lazy to convert it. http://weblogs.asp.net/kennykerr/archive/2007/01/23/controls-and-the-desktop-window-manager.aspx Note: If I ever succeed with the BufferedPaint methods, I swear to s/o that I will make a simple DLL with all the common Windows Forms controls drawable on glass.

  • Why does C# thread die?

    - by JackN
    This is my 1st C# project so I may be doing something obviously improper in the code below. I am using .NET, WinForms (I think), and this is a desktop application until I get the bugs out. UpdateGui() uses Invoke((MethodInvoker)delegate to update various GUI controls based on received serial data and sends a GetStatus() command out the serial port 4 times a second. Thread Read() reads the response from serial port whenever it arrives which should be near immediate. SerialPortFixer is a SerialPort IOException Workaround in C# I found at http://zachsaw.blogspot.com/2010/07/serialport-ioexception-workaround-in-c.html. After one or both threads die I'll see something like The thread 0x1288 has exited with code 0 (0x0). in the debug code output. Why do UpdateGui() and/or Read() eventually die? public partial class UpdateStatus : Form { private readonly byte[] Command = new byte[32]; private readonly byte[] Status = new byte[32]; readonly Thread readThread; private static readonly Mutex commandMutex = new Mutex(); private static readonly Mutex statusMutex = new Mutex(); ... public UpdateStatus() { InitializeComponent(); SerialPortFixer.Execute("COM2"); if (serialPort1.IsOpen) { serialPort1.Close(); } try { serialPort1.Open(); } catch (Exception e) { labelWarning.Text = LOST_COMMUNICATIONS + e; labelStatus.Text = LOST_COMMUNICATIONS + e; labelWarning.Visible = true; } readThread = new Thread(Read); readThread.Start(); new Timer(UpdateGui, null, 0, 250); } static void ProcessStatus(byte[] status) { Status.State = (State) status[4]; Status.Speed = status[6]; // MSB Status.Speed *= 256; Status.Speed += status[5]; var Speed = Status.Speed/GEAR_RATIO; Status.Speed = (int) Speed; ... } public void Read() { while (serialPort1 != null) { try { serialPort1.Read(Status, 0, 1); if (Status[0] != StartCharacter[0]) continue; serialPort1.Read(Status, 1, 1); if (Status[1] != StartCharacter[1]) continue; serialPort1.Read(Status, 2, 1); if (Status[2] != (int)Command.GetStatus) continue; serialPort1.Read(Status, 3, 1); ... statusMutex.WaitOne(); ProcessStatus(Status); Status.update = true; statusMutex.ReleaseMutex(); } catch (Exception e) { Console.WriteLine(@"ERROR!

  • Changing the background color of a view in real-time.

    - by Tarmon
    Hey Everyone, I am trying to implement a ListView that is composed of rows that contain a View on the left followed by a TextView to the right of that.

  • How to associate newly created SurfaceHolder to MediaPlayer

    - by fayerth
    In my code, I want to be able to temporarily hide (and subsequently show) a video. I am using a SurfaceView + MediaPlayer combination instead of the VideoView due to requirements. However, I am facing difficulties in getting video playback to occur as expected after I show the SurfaceView. My code excerpts includes the following: public void show() { if (mSurface != null) mSurface.setVisibility(View.VISIBLE); } public void hide() { if (mSurface != null) { if (isInPlaybackState()) pause(); mSurface.setVisibility(View.INVISIBLE); } } @Override public void surfaceCreated(final SurfaceHolder holder) { mHolder = holder; openVideo(); } @Override public void surfaceDestroyed(final SurfaceHolder holder) { // After this, the surface can't be used again mHolder = null; } private void openVideo() { if (mAssetPath == null || !mAssetPath.isEmpty() || mHolder == null) { // Not ready yet; try again later return; } // Pause music playback service Intent i = new Intent("com.android.music.musicservicecommand"); i.putExtra("command", "pause"); getActivity().sendBroadcast(i); if (mPlayer == null) { initializePlayer(); } else { mPlayer.setDisplay(mHolder); } } Based on the above, when I call hide(), surfaceDestroyed(SurfaceHolder) gets triggered. When I later call show(), surfaceCreated(SurfaceHolder) gets triggered, which will call openVideo() and associate the player with the newly provided SurfaceHolder. The above works as expected, and I believe this should be the correct process; however, when I call mPlayer.start(), I would hear the video's audio playing without any video and see the following error messages (which eventually causes the media playback to stop and complete, as noted by the disconnect logs): 10-23 11:29:42.775: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.795: E/MediaPlayer(4204): Error (-38,0) 10-23 11:29:42.805: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.810: V/MediaPlayer(4204): message received msg=100, ext1=1, ext2=-2147483648 10-23 11:29:42.810: E/MediaPlayer(4204): error (1, -2147483648) 10-23 11:29:42.810: V/MediaPlayer(4204): callback application 10-23 11:29:42.810: V/MediaPlayer(4204): back from callback 10-23 11:29:42.825: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.850: V/MediaPlayer-JNI(4204): getCurrentPosition: 671668 (msec) 10-23 11:29:42.850: V/MediaPlayer-JNI(4204): getCurrentPosition: 671668 (msec) 10-23 11:29:42.850: V/MediaPlayer(4204): message received msg=100, ext1=1, ext2=-2147483648 10-23 11:29:42.850: E/MediaPlayer(4204): error (1, -2147483648) 10-23 11:29:42.850: V/MediaPlayer(4204): callback application 10-23 11:29:42.850: V/MediaPlayer(4204): back from callback 10-23 11:29:42.875: V/MediaPlayer-JNI(4204): stop 10-23 11:29:42.875: V/MediaPlayer(4204): stop 10-23 11:29:42.875: E/MediaPlayer(4204): stop called in state 0 10-23 11:29:42.875: V/MediaPlayer(4204): message received msg=100, ext1=-38, ext2=0 10-23 11:29:42.875: E/MediaPlayer(4204): error (-38, 0) 10-23 11:29:42.875: V/MediaPlayer(4204): callback application 10-23 11:29:42.875: V/MediaPlayer(4204): back from callback 10-23 11:29:42.875: V/MediaPlayer-JNI(4204): reset 10-23 11:29:42.875: V/MediaPlayer(4204): reset 10-23 11:29:42.900: V/MediaPlayer-JNI(4204): release 10-23 11:29:42.900: V/MediaPlayer(4204): setListener 10-23 11:29:42.900: V/MediaPlayer(4204): disconnect 10-23 11:29:42.910: V/MediaPlayer(4204): destructor 10-23 11:29:42.910: V/MediaPlayer(4204): disconnect Has anyone encountered this issue before and found a workaround?

  • How to determine if two generic type values are equal?

    - by comecme
    I'm trying to figure out how I can successfully determine if two generic type values are equal to each other. Based on Mark Byers' answer on this question I would think I can just use value.Equals() where value is a generic type. My actual problem is in a LinkedList implementation, but the problem can be shown with this simpler example. class GenericOjbect<T> { public T Value { get; private set; } public GenericOjbect(T value) { Value = value; } public bool Equals(T value) { return (Value.Equals(value)); } } Now I define an instance of GenericObject<StringBuilder> containing new StringBuilder("StackOverflow"). I would expect to get true if I call Equals(new StringBuilder("StackOverflow") on this GenericObject instance, but I get false. A sample program showing this: using System; using System.Text; class Program { static void Main() { var sb1 = new StringBuilder("StackOverflow"); var sb2 = new StringBuilder("StackOverflow"); Console.WriteLine("StringBuilder compare"); Console.WriteLine("1. == " + (sb1 == sb2)); Console.WriteLine("2. Object.Equals " + (Object.Equals(sb1, sb2))); Console.WriteLine("3. this.Equals " + (sb1.Equals(sb2))); var go1 = new GenericOjbect<StringBuilder>(sb1); var go2 = new GenericOjbect<StringBuilder>(sb2); Console.WriteLine("\nGenericObject compare"); Console.WriteLine("1. == " + (go1 == go2)); Console.WriteLine("2. Object.Equals " + (Object.Equals(go1, go2))); Console.WriteLine("3. this.Equals " + (go1.Equals(go2))); Console.WriteLine("4. Value.Equals " + (go1.Value.Equals(go2.Value))); } } For the three methods of comparing two StringBuilder objects, only the StringBuilder.Equals instance method (the third line) returns true. This is what I expected. But when comparing the GenericObject objects, its Equals() method (the third line) returns false. Interestingly enough, the fourth compare method does return true. I'd think the third and fourth comparison are actually doing the same thing. I would have expected true. Because in the Equals() method of the GenericObject class, both value and Value are of type T which in this case is a StringBuilder. Based on Mark Byers' answer in this question, I would've expected the Value.Equals() method to be using the StringBuilder's Equals() method. And as I've shown, the StringBuilder's Equal() method does return true. I've even tried public bool Equals(T value) { return EqualityComparer<T>.Default.Equals(Value, value); } but that also returns false. So, two questions here: Why doesn't the code return true? How could I implement the Equals method so it does return true?

  • Windows Phone 7 Connect to SharePoint via SOAP

    I am making my second application for the Windows 7 Phone Series platform and I cannot seem to connect to a SharePoint server using https. 99% of the following is not my code. I have borrowed it from http://blog.daisley-harrison.com/blog/post/Practical-Silverlight-and-SharePoint-Integration-Part-Two.aspx untill I can further understand how SOAP works in W7P Series.

Any idea whats the problem here? package{ import flash.display.MovieClip; import flash.display.DisplayObject; import flash.events.Event; import flash.events.TimerEvent; import flash.utils.Timer; public class clockFunction extends MovieClip { private var clock:clockMC=new clockMC(); private var countdownTimer:Timer; //seconds private var secTop1=clock.second.top1.digit; private var secTop2=clock.second.top2.digit; private var secBot1=clock.second.bot1.digit; private var secBot2=clock.second.bot2.digit; private var seconds:Number; private var minutes:Number; private var hours:Number; private var days:Number; public function clockFunction():void { decrease(); addChild(clock); } private function decrease():void { countdownTimer=new Timer(1000); //Adding an event listener to the timer object countdownTimer.addEventListener(TimerEvent.TIMER,updateTime); //Initializing timer object //countdownTimer.start(); } private function updateTime(event:TimerEvent):void { decreasTimerFunction(); clock.second.play(); if (seconds==1) { clock.minute.play(); } if ((minutes==1)&&(seconds==1)) { clock.hour.play(); } if ((hours==1)&&(minutes==1)&&(seconds==1)) { clock.day.play(); } } //Setting it back to its correct time so it won't have number changing in between of flipping issues. private function detect(event:Event):void { //seconds var sec1=seconds; var sec2=seconds-1; if (sec1<10) { sec1="0"+sec1; } if (sec2<10) { sec2="0"+sec2; } if (sec1==00) { sec2=59; } secTop1.text=sec1; secTop2.text=sec2; secBot1.text=sec1; secBot2.text=sec2; } public function startTime():void { addEventListener(Event.ENTER_FRAME,detect); countdownTimer.start(); trace("start"); } public function stopTime():void { countdownTimer.stop(); removeEventListener(Event.ENTER_FRAME,detect); trace("stop"); } private function decreasTimerFunction():void { //Create a date object for Christmas Morning var endTime:Date=new Date(2010,3,26,20,0,0); //Current date object var now:Date=new Date(); // Set the difference between the two date and times in milliseconds var timeDiff:Number=endTime.getTime()-now.getTime(); seconds=Math.floor(timeDiff/1000); minutes=Math.floor(seconds/60); hours=Math.floor(minutes/60); days=Math.floor(hours/24); // Set the remainder of the division vars above hours%=24; minutes%=60; seconds%=60; } } }

  • Rendering a view to a string in MVC, then redirecting -- workarounds?

    - by James S
    Hi -- I can't render a view to a string and then redirect, despite this answer from Feb (after version 1.0, I think) that claims it's possible. I thought I was doing something wrong, and then I read this answer from Haack in July that claims it's not possible. If somebody has it working and can help me get it working, that's great (and I'll post code, errors). However, I'm now at the point of needing workarounds. There are a few, but nothing ideal. Has anybody solved this, or have any comments on my ideas? This is to render email. While I can surely send the email outside of the web request (store info in a db and get it later), there are many types of emails and I don't want to store the template data (user object, a few other LINQ objects) in a db to let it get rendered later. I could create a simpler, serializable POCO and save that in the db, but why? ... I just want rendered text! I can create a new RedirectToAction object that checks if the headers have been sent (can't figure out how to do this -- try/catch?) and, if so, builds out a simple page with a meta redirect, a javascript redirect, and also a "click here" link. Within my controller, I can remember if I've rendered an email and, if so, manually do #2 by displaying a view. I can manually send the redirect headers before any potential email rendering. Then, rather than using the MVC infrastructure to redirecttoaction, I just call result.end. This seems easiest, but really messy. Anything else? EDIT: I've tried Dan's code (very similar to the code from Jan/Feb that I've already tried) and I'm still getting the same error. The only substantial difference I can see is that his example uses a view while I use a partial view. I'll try testing this later with a view. Here's what I've got: Controller public ActionResult Certifications(string email_intro) { //a lot of stuff ViewData["users"] = users; if (isPost()) { //create the viewmodel var view_model = new ViewModels.Emails.Certifications.Open(userContext) { emailIntro = email_intro }; //i've tried stopping this after just one iteration, in case the problem is due to calling it multiple times foreach (var user in users) { if (user.Email_Address.IsValidEmailAddress()) { //add more stuff to the view model specific to this user view_model.user = user; view_model.certification302Summary.subProcessesOwner = new SubProcess_Certifications(RecordUpdating.Role.Owner, null, null, user.User_ID, repository); //more here.... //if i comment out the next line, everything works ok SendEmail(view_model, this.ControllerContext); } } return RedirectToAction("Certifications"); } return View(); } SendEmail() public static void SendEmail(ViewModels.Emails.Certifications.Open model, ControllerContext context) { var vd = context.Controller.ViewData; vd["model"] = model; var renderer = new CustomRenderers(); //i fixed an error in your code here var text = renderer.RenderViewToString3(context, "~/Views/Emails/Certifications/Open.ascx", "", vd, null); var a = text; } CustomRenderers public class CustomRenderers { public virtual string RenderViewToString3(ControllerContext controllerContext, string viewPath, string masterPath, ViewDataDictionary viewData, TempDataDictionary tempData) { //copy/paste of dan's code } } Error [HttpException (0x80004005): Cannot redirect after HTTP headers have been sent.] System.Web.HttpResponse.Redirect(String url, Boolean endResponse) +8707691 Thanks, James

  • Domain Validation in a CQRS architecture

    - by Jupaol
    Basically I want to know if there is a better way to validate my domain entities. This is how I am planning to do it but I would like your opinion The first approach I considered was: class Customer : EntityBase<Customer> { public void ChangeEmail(string email) { if(string.IsNullOrWhitespace(email)) throw new DomainException(“...”); if(!email.IsEmail()) throw new DomainException(); if(email.Contains(“@mailinator.com”)) throw new DomainException(); } } I actually do not like this validation because even when I am encapsulating the validation logic in the correct entity, this is violating the Open/Close principle (Open for extension but Close for modification) and I have found that violating this principle, code maintenance becomes a real pain when the application grows up in complexity. Why? Because domain rules change more often than we would like to admit, and if the rules are hidden and embedded in an entity like this, they are hard to test, hard to read, hard to maintain but the real reason why I do not like this approach is: if the validation rules change, I have to come and edit my domain entity. This has been a really simple example but in RL the validation could be more complex So following the philosophy of Udi Dahan, making roles explicit, and the recommendation from Eric Evans in the blue book, the next try was to implement the specification pattern, something like this class EmailDomainIsAllowedSpecification : IDomainSpecification<Customer> { private INotAllowedEmailDomainsResolver invalidEmailDomainsResolver; public bool IsSatisfiedBy(Customer customer) { return !this.invalidEmailDomainsResolver.GetInvalidEmailDomains().Contains(customer.Email); } } But then I realize that in order to follow this approach I had to mutate my entities first in order to pass the value being valdiated, in this case the email, but mutating them would cause my domain events being fired which I wouldn’t like to happen until the new email is valid So after considering these approaches, I came out with this one, since I am going to implement a CQRS architecture: class EmailDomainIsAllowedValidator : IDomainInvariantValidator<Customer, ChangeEmailCommand> { public void IsValid(Customer entity, ChangeEmailCommand command) { if(!command.Email.HasValidDomain()) throw new DomainException(“...”); } } Well that’s the main idea, the entity is passed to the validator in case we need some value from the entity to perform the validation, the command contains the data coming from the user and since the validators are considered injectable objects they could have external dependencies injected if the validation requires it. Now the dilemma, I am happy with a design like this because my validation is encapsulated in individual objects which brings many advantages: easy unit test, easy to maintain, domain invariants are explicitly expressed using the Ubiquitous Language, easy to extend, validation logic is centralized and validators can be used together to enforce complex domain rules. And even when I know I am placing the validation of my entities outside of them (You could argue a code smell - Anemic Domain) but I think the trade-off is acceptable But there is one thing that I have not figured out how to implement it in a clean way. How should I use this components... Since they will be injected, they won’t fit naturally inside my domain entities, so basically I see two options: Pass the validators to each method of my entity Validate my objects externally (from the command handler) I am not happy with the option 1 so I would explain how I would do it with the option 2 class ChangeEmailCommandHandler : ICommandHandler<ChangeEmailCommand> { public void Execute(ChangeEmailCommand command) { private IEnumerable<IDomainInvariantValidator> validators; // here I would get the validators required for this command injected, and in here I would validate them, something like this using (var t = this.unitOfWork.BeginTransaction()) { var customer = this.unitOfWork.Get<Customer>(command.CustomerId); this.validators.ForEach(x =. x.IsValid(customer, command)); // here I know the command is valid // the call to ChangeEmail will fire domain events as needed customer.ChangeEmail(command.Email); t.Commit(); } } } Well this is it. Can you give me your thoughts about this or share your experiences with Domain entities validation EDIT I think it is not clear from my question, but the real problem is: Hiding the domain rules has serious implications in the future maintainability of the application, and also domain rules change often during the life-cycle of the app. Hence implementing them with this in mind would let us extend them easily. Now imagine in the future a rules engine is implemented, if the rules are encapsulated outside of the domain entities, this change would be easier to implement

  • Mismatched coordinate systems in LWJGL with Mouse and Textures

    - by Braains
    I'm not really sure how to expand on this other than to say that it appears that my LWJGL seems to have different coordinate systems for the Mouse and for painting Textures. It seems that Textures have the usual Java2D way of putting (0, 0) in the upper-left corner, while the Mouse goes by the more sensible way of having the origin in the lower-left corner. I've checked my code a bunch but I don't see anything modifying the values between where I read them and where I use them. It's thrown me for a loop and I can't quite figure it out. I'll post all the code that involves the Mouse input and Texture painting for you guys to look at. private static void pollHelpers() { while(Mouse.next()) { InputHelper.acceptMouseInput(Mouse.getEventButton(), Mouse.getEventX(), Mouse.getEventY()); } while (Keyboard.next()) { if (Keyboard.getEventKeyState()) { InputHelper.acceptKeyboardInput(Keyboard.getEventKey(), true); } else { InputHelper.acceptKeyboardInput(Keyboard.getEventKey(), false); } } } public static void acceptMouseInput(int mouseButton, int x, int y) { for(InputHelper ie: InputHelper.instances) { if(ie.checkRectangle(x, y)) { ie.sendMouseInputToParent(mouseButton); } } } private void sendMouseInputToParent(int mouseButton) { parent.onClick(mouseButton); } public boolean checkRectangle(int x, int y) { //y = InputManager.HEIGHT - y; See below for explanation return x > parent.getX() && x < parent.getX() + parent.getWidth() && y > parent.getY() && y < parent.getY() + parent.getHeight(); } I put this line of code in because it temporarily fixed the coordinate system problem. However, I want to have my code to be as independent as possible so I want to remove as much reliance on other classes as possible. These are the only methods that touch the Mouse input, and as far as I can tell none of them change anything so all is good here. Now for the Texture methods: public void draw() { if(!clicked || deactivatedImage == null) { activatedImage.bind(); glBegin(GL_QUADS); { DrawHelper.drawGLQuad(activatedImage, x, y, width, height); } glEnd(); } else { deactivatedImage.bind(); glBegin(GL_QUADS); { DrawHelper.drawGLQuad(deactivatedImage, x, y, width, height); } glEnd(); } } public static void drawGLQuad(Texture texture, float x, float y, float width, float height) { glTexCoord2f(x, y); glVertex2f(x, y); glTexCoord2f(x, y + texture.getHeight()); glVertex2f(x, y + height); glTexCoord2f(x + texture.getWidth(), y + texture.getHeight()); glVertex2f(x + width, y +height); glTexCoord2f(x + texture.getWidth(), y); glVertex2f(x + width, y); } I'll be honest, I do not have the faintest clue as to what is really happening in this method but I was able to put it together on my own and get it to work. my guess is that this is where the problem is. Thanks for any help!

  • Architecture for Qt SIGNAL with subclass-specific, templated argument type

    - by Barry Wark
    I am developing a scientific data acquisition application using Qt. Since I'm not a deep expert in Qt, I'd like some architecture advise from the community on the following problem: The application supports several hardware acquisition interfaces but I would like to provide an common API on top of those interfaces. Each interface has a sample data type and a units for its data. So I'm representing a vector of samples from each device as a std::vector of Boost.Units quantities (i.e. std::vector<boost::units::quantity<unit,sample_type> >). I'd like to use a multi-cast style architecture, where each data source broadcasts newly received data to 1 or more interested parties. Qt's Signal/Slot mechanism is an obvious fit for this style. So, I'd like each data source to emit a signal like typedef std::vector<boost::units::quantity<unit,sample_type> > SampleVector signals: void samplesAcquired(SampleVector sampleVector); for the unit and sample_type appropriate for that device. Since tempalted QObject subclasses aren't supported by the meta-object compiler, there doesn't seem to be a way to have a (tempalted) base class for all data sources which defines the samplesAcquired Signal. In other words, the following won't work: template<T,U> //sample type and units class DataSource : public QObject { Q_OBJECT ... public: typedef std::vector<boost::units::quantity<U,T> > SampleVector signals: void samplesAcquired(SampleVector sampleVector); }; The best option I've been able to come up with is a two-layered approach: template<T,U> //sample type and units class IAcquiredSamples { public: typedef std::vector<boost::units::quantity<U,T> > SampleVector virtual shared_ptr<SampleVector> acquiredData(TimeStamp ts, unsigned long nsamples); }; class DataSource : public QObject { ... signals: void samplesAcquired(TimeStamp ts, unsigned long nsamples); }; The samplesAcquired signal now gives a timestamp and number of samples for the acquisition and clients must use the IAcquiredSamples API to retrieve those samples. Obviously data sources must subclass both DataSource and IAcquiredSamples. The disadvantage of this approach appears to be a loss of simplicity in the API... it would be much nicer if clients could get the acquired samples in the Slot connected. Being able to use Qt's queued connections would also make threading issues easier instead of having to manage them in the acquiredData method within each subclass. One other possibility, is to use a QVariant argument. This necessarily puts the onus on subclass to register their particular sample vector type with Q_REGISTER_METATYPE/qRegisterMetaType. Not really a big deal. Clients of the base class however, will have no way of knowing what type the QVariant value type is, unless a tag struct is also passed with the signal. I consider this solution at least as convoluted as the one above, as it forces clients of the abstract base class API to deal with some of the gnarlier aspects of type system. So, is there a way to achieve the templated signal parameter? Is there a better architecture than the one I've proposed?

  • VS2008 Windows Form Designer does not like my control.

    - by Thedric Walker
    I have a control that is created like so: public partial class MYControl : MyControlBase { public string InnerText { get { return textBox1.Text; } set { textBox1.Text = value; } } public MYControl() { InitializeComponent(); } } partial class MYControl { /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.IContainer components = null; /// <summary> /// Clean up any resources being used. /// </summary> /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } #region Component Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { this.textBox1 = new System.Windows.Forms.TextBox(); this.listBox1 = new System.Windows.Forms.ListBox(); this.label1 = new System.Windows.Forms.Label(); this.SuspendLayout(); // // textBox1 // this.textBox1.Location = new System.Drawing.Point(28, 61); this.textBox1.Name = "textBox1"; this.textBox1.Size = new System.Drawing.Size(100, 20); this.textBox1.TabIndex = 0; // // listBox1 // this.listBox1.FormattingEnabled = true; this.listBox1.Location = new System.Drawing.Point(7, 106); this.listBox1.Name = "listBox1"; this.listBox1.Size = new System.Drawing.Size(120, 95); this.listBox1.TabIndex = 1; // // label1 // this.label1.AutoSize = true; this.label1.Location = new System.Drawing.Point(91, 42); this.label1.Name = "label1"; this.label1.Size = new System.Drawing.Size(35, 13); this.label1.TabIndex = 2; this.label1.Text = "label1"; // // MYControl // this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.Controls.Add(this.label1); this.Controls.Add(this.listBox1); this.Controls.Add(this.textBox1); this.Name = "MYControl"; this.Size = new System.Drawing.Size(135, 214); this.ResumeLayout(false); this.PerformLayout(); } #endregion private System.Windows.Forms.Label label1; } MyControlBase contains the definition for the ListBox and TextBox. Now when I try to view this control in the Form Designer it gives me these errors: The variable 'listBox1' is either undeclared or was never assigned. The variable 'textBox1' is either undeclared or was never assigned. This is obviously wrong as they are defined in MyControlBase with public access. Is there any way to massage Form Designer into allowing me to visually edit my control?
