• Source Control and SQL Development &ndash; Part 3

  - by Ajarn Mark Caldwell

  In parts one and two of this series, I have been specifically focusing on the latest version of SQL Source Control by Red Gate Software.  But I have been doing source-controlled SQL development for years, long before this product was available, and well before Microsoft came out with Database Projects for Visual Studio.  “So, how does that work?” you may wonder.  Well, let me share some of the details of how we do it where I work… The key to this approach is that everything is done via Transact-SQL script files; either natively written T-SQL, or generated.  My preference is to write all my code by hand, which forces you to become better at your SQL syntax.  But if you really prefer to use the Management Studio GUI to make database changes, you can still do that, and then you use the Generate Scripts feature of the GUI to produce T-SQL scripts afterwards, and store those in your source control system.  You can generate scripts for things like stored procedures and views by right-clicking on the database in the Object Explorer, and Choosing Tasks, Generate Scripts (see figure 1 to the left).  You can also do that for the CREATE scripts for tables, but that does not work when you have a table that is already in production, and you need to make just a simple change, such as adding a new column or index.  In this case, you can use the GUI to make the table changes, and then instead of clicking the Save button, click the Generate Change Script button (). Then, once you have saved the change script, go ahead and execute it on your development database to actually make the change.  I believe that it is important to actually execute the script rather than just click the Save button because this is your first test that your change script is working and you didn’t somehow lose a portion of the change. As you can imagine, all this generating of scripts can get tedious and tempting to skip entirely, so again, I would encourage you to just get in the habit of writing your own Transact-SQL code, and then it is just a matter of remembering to save your work, just like you are in the habit of saving changes to a Word or Excel document before you exit the program. So, now that you have all of these script files, what do you do with them?  Well, we organize ours into folders labeled ChangeScripts, Functions, Views, and StoredProcedures, and those folders are loaded into our source control system.  ChangeScripts contains all of the table and index changes, and anything else that is basically a one-time-only execution.  Of course you want to write your scripts with qualifying logic so that if a script were accidentally run more than once in a database, it would not crash nor corrupt anything; but these scripts are really intended to be run only once in a database. Once you have your initial set of scripts loaded into source control, then making changes, such as altering a stored procedure becomes a simple matter of checking out your CREATE PROCEDURE* script, editing it in SSMS, saving the change, executing the script in order to effect the change in your database, and then checking the script back in to source control.  Of course, this is where the lack of integration for source control systems within SSMS becomes an irritation, because this means that in addition to SSMS, I also have my source control client application running to do the check-out and check-in.  And when you have 800+ procedures like we do, that can be quite tedious to locate the procedure I want to change in source control, check it out, then locate the script file in my working folder, open it in SSMS, do the change, save it, and the go back to source control to check in.  Granted, it is not nearly as burdensome as, say, losing your source code and having to rebuild it from memory, or losing the audit trail that good source control systems provide.  It is worth the effort, and this is how I have been doing development for the last several years. Remember that everything that the SQL Server Management Studio does in modifying your database can also be done in plain Transact-SQL code, and this is what you are storing.  And now I have shown you how you can do it all without spending any extra money.  You already have source control, or can get free, open-source source control systems (almost seems like an oxymoron, doesn’t it) and of course Management Studio is free with your SQL Server database engine software. So, whether you spend the money on tools to make it easier, or not, you now have no excuse for not using source control with your SQL development. * In our current model, the scripts for stored procedures and similar database objects are written with an IF EXISTS…DROP… at the top, followed by the CREATE PROCEDURE… section, and that followed by a section that assigns permissions.  This allows me to run the same script regardless of whether the procedure previously existed in the database.  If the script was only an ALTER PROCEDURE, then it would fail the first time that procedure was deployed to a database, unless you wrote other code to stub it if it did not exist.  There are a few different ways you could organize your scripts for deployment, each with its own trade-offs, but I think it is absolutely critical that whichever way you organize things, you ensure that the same script is run throughout the deployment cycle, and do not allow customizations to creep in between TEST and PROD.  If you do, then you have broken the integrity of your deployment process because what you deployed to PROD was not exactly the same as what was tested in TEST, so you effectively have now released untested code into PROD.

• Trying to implement fling events on an object

  - by Adam Short

  I have a game object, well a bitmap, which I'd like to "fling". I'm struggling to get it to fling ontouchlistener due to it being a bitmap and not sure how to proceed and I'm struggling to find the resources to help. Here's my code so far: https://github.com/addrum/Shapes GameActivity class: package com.main.shapes; import android.app.Activity; import android.content.Context; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.Canvas; import android.os.Bundle; import android.view.GestureDetector; import android.view.MotionEvent; import android.view.SurfaceHolder; import android.view.SurfaceView; import android.view.View.OnTouchListener; import android.view.Window; public class GameActivity extends Activity { private GestureDetector gestureDetector; View view; Bitmap ball; float x, y; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //Remove title bar this.requestWindowFeature(Window.FEATURE_NO_TITLE); view = new View(this); ball = BitmapFactory.decodeResource(getResources(), R.drawable.ball); gestureDetector = new GestureDetector(this, new GestureListener()); x = 0; y = 0; setContentView(view); ball.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(android.view.View v, MotionEvent event) { // TODO Auto-generated method stub return false; } }); } @Override protected void onPause() { super.onPause(); view.pause(); } @Override protected void onResume() { super.onResume(); view.resume(); } public class View extends SurfaceView implements Runnable { Thread thread = null; SurfaceHolder holder; boolean canRun = false; public View(Context context) { super(context); holder = getHolder(); } public void run() { while (canRun) { if (!holder.getSurface().isValid()) { continue; } Canvas c = holder.lockCanvas(); c.drawARGB(255, 255, 255, 255); c.drawBitmap(ball, x - (ball.getWidth() / 2), y - (ball.getHeight() / 2), null); holder.unlockCanvasAndPost(c); } } public void pause() { canRun = false; while (true) { try { thread.join(); } catch (InterruptedException e) { e.printStackTrace(); } break; } thread = null; } public void resume() { canRun = true; thread = new Thread(this); thread.start(); } } } GestureListener class: package com.main.shapes; import android.view.GestureDetector.SimpleOnGestureListener; import android.view.MotionEvent; public class GestureListener extends SimpleOnGestureListener { private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_THRESHOLD_VELOCITY = 200; @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { //From Right to Left return true; } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { //From Left to Right return true; } if (e1.getY() - e2.getY() > SWIPE_MIN_DISTANCE && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) { //From Bottom to Top return true; } else if (e2.getY() - e1.getY() > SWIPE_MIN_DISTANCE && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) { //From Top to Bottom return true; } return false; } @Override public boolean onDown(MotionEvent e) { //always return true since all gestures always begin with onDown and<br> //if this returns false, the framework won't try to pick up onFling for example. return true; } }

• Rebuilding CoasterBuzz, Part IV: Dependency injection, it's what's for breakfast

  - by Jeff

  (Repost from my personal blog.) This is another post in a series about rebuilding one of my Web sites, which has been around for 12 years. I hope to relaunch soon. More: Part I: Evolution, and death to WCF Part II: Hot data objects Part III: The architecture using the "Web stack of love" If anything generally good for the craft has come out of the rise of ASP.NET MVC, it's that people are more likely to use dependency injection, and loosely couple the pieces parts of their applications. A lot of the emphasis on coding this way has been to facilitate unit testing, and that's awesome. Unit testing makes me feel a lot less like a hack, and a lot more confident in what I'm doing. Dependency injection is pretty straight forward. It says, "Given an instance of this class, I need instances of other classes, defined not by their concrete implementations, but their interfaces." Probably the first place a developer exercises this in when having a class talk to some kind of data repository. For a very simple example, pretend the FooService has to get some Foo. It looks like this: public class FooService {    public FooService(IFooRepository fooRepo)    {       _fooRepo = fooRepo;    }    private readonly IFooRepository _fooRepo;    public Foo GetMeFoo()    {       return _fooRepo.FooFromDatabase();    } } When we need the FooService, we ask the dependency container to get it for us. It says, "You'll need an IFooRepository in that, so let me see what that's mapped to, and put it in there for you." Why is this good for you? It's good because your FooService doesn't know or care about how you get some foo. You can stub out what the methods and properties on a fake IFooRepository might return, and test just the FooService. I don't want to get too far into unit testing, but it's the most commonly cited reason to use DI containers in MVC. What I wanted to mention is how there's another benefit in a project like mine, where I have to glue together a bunch of stuff. For example, when I have someone sign up for a new account on CoasterBuzz, I'm actually using POP Forums' new account mailer, which composes a bunch of text that includes a link to verify your account. The thing is, I want to use custom text and some other logic that's specific to CoasterBuzz. To accomplish this, I make a new class that inherits from the forum's NewAccountMailer, and override some stuff. Easy enough. Then I use Ninject, the DI container I'm using, to unbind the forum's implementation, and substitute my own. Ninject uses something called a NinjectModule to bind interfaces to concrete implementations. The forum has its own module, and then the CoasterBuzz module is loaded second. The CB module has two lines of code to swap out the mailer implementation: Unbind<PopForums.Email.INewAccountMailer>(); Bind<PopForums.Email.INewAccountMailer>().To<CbNewAccountMailer>(); Piece of cake! Now, when code asks the DI container for an INewAccountMailer, it gets my custom implementation instead. This is a lot easier to deal with than some of the alternatives. I could do some copy-paste, but then I'm not using well-tested code from the forum. I could write stuff from scratch, but then I'm throwing away a bunch of logic I've already written (in this case, stuff around e-mail, e-mail settings, mail delivery failures). There are other places where the DI container comes in handy. For example, CoasterBuzz does a number of custom things with user profiles, and special content for paid members. It uses the forum as the core piece to managing users, so I can ask the container to get me instances of classes that do user lookups, for example, and have zero care about how the forum handles database calls, configuration, etc. What a great world to live in, compared to ten years ago. Sure, the primary interest in DI is around the "separation of concerns" and facilitating unit testing, but as your library grows and you use more open source, it starts to be the glue that pulls everything together.

• OAuth + Twitter on Android: Callback fails

  - by Samuh

  My Android application uses Java OAuth library, found here for authorization on Twitter. I am able to get a request token, authorize the token and get an acknowlegement but when the browser tries the call back url to reconnect with my application, it does not use the URL I provide in code, but uses the one I supplied while registering with Twitter. Note: 1. When registering my application with twitter, I provided a hypothetical call back url:http://abz.xyc.com and set the application type as browser. 2. I provided a callback url in my code "myapp" and have added an intent filter for my activity with Browsable category and data scheme as "myapp". 3. URL called when authorizing does contain te callback url, I specified in code. Any idea what I am doing wrong here? Relevant Code: public class FirstActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); OAuthAccessor client = defaultClient(); Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(client.consumer.serviceProvider.userAuthorizationURL + "?oauth_token=" + client.requestToken + "&oauth_callback=" + client.consumer.callbackURL)); startActivity(i); } OAuthServiceProvider defaultProvider() { return new OAuthServiceProvider(GeneralRuntimeConstants.request_token_URL, GeneralRuntimeConstants.authorize_url, GeneralRuntimeConstants.access_token_url); } OAuthAccessor defaultClient() { String callbackUrl = "myapp:///"; OAuthServiceProvider provider = defaultProvider(); OAuthConsumer consumer = new OAuthConsumer(callbackUrl, GeneralRuntimeConstants.consumer_key, GeneralRuntimeConstants.consumer_secret, provider); OAuthAccessor accessor = new OAuthAccessor(consumer); OAuthClient client = new OAuthClient(new HttpClient4()); try { client.getRequestToken(accessor); } catch (Exception e) { e.printStackTrace(); } return accessor; } @Override protected void onResume() { // TODO Auto-generated method stub super.onResume(); Uri uri = this.getIntent().getData(); if (uri != null) { String access_token = uri.getQueryParameter("oauth_token"); } } } // Manifest file <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".FirstActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="myapp"/> </intent-filter> </activity> </application>

• RhinoMocks AAA Syntax

  - by Bill Campbell

  Hi, I've spent a good part of the day trying to figure out why a simple RhinoMocks test doesn't return the value I'm setting in the return. I'm sure that I'm just missing something really simple but I can't figure it out. Here's my test: [TestMethod] public void CopyvRAFiles_ShouldCallCopyvRAFiles_ShouldReturnTrue2() { FileInfo fi = new FileInfo(@"c:\Myprogram.txt"); FileInfo[] myFileInfo = new FileInfo[2]; myFileInfo[0] = fi; myFileInfo[1] = fi; var mockSystemIO = MockRepository.GenerateMock<ISystemIO>(); mockSystemIO.Stub(x => x.GetFilesForCopy("c:")).Return(myFileInfo); mockSystemIO.Expect(y => y.FileCopyDateCheck(@"c:\Myprogram.txt", @"c:\Myprogram.txt")).Return("Test"); CopyFiles copy = new CopyFiles(mockSystemIO); List<string> retValue = copy.CopyvRAFiles("c:", "c:", new AdminWindowViewModel(vRASharedData)); mockSystemIO.VerifyAllExpectations(); } I have an interface for my SystemIO class I'm passing in a mock for that to my CopyFiles class. I'm setting an expectation on my FileCopyDatCheck method and saying that it should Return("Test"). When I step through the code, it returns a null insteaed. Any ideas what I'm missing here? Here's my CopyFiles class Method: public List<string> CopyvRAFiles(string currentDirectoryPath, string destPath, AdminWindowViewModel adminWindowViewModel) { string fileCopied; List<string> filesCopied = new List<string>(); try { sysIO.CreateDirectoryIfNotExist(destPath); FileInfo[] files = sysIO.GetFilesForCopy(currentDirectoryPath); if (files != null) { foreach (FileInfo file in files) { fileCopied = sysIO.FileCopyDateCheck(file.FullName, destPath + file.Name); filesCopied.Add(fileCopied); } } //adminWindowViewModel.CheckFilesThatRequireSystemUpdate(filesCopied); return filesCopied; } catch (Exception ex) { ExceptionPolicy.HandleException(ex, "vRAClientPolicy"); Console.WriteLine("{0} Exception caught.", ex); ShowErrorMessageDialog(ex); return null; } } I would think that "fileCopied" would have the Return value set by the Expect. The GetFilesForCopy returns the two files in myFileInfo. Please Help. :) thanks in advance!

• gwt-RPC problem! what is the best practice on using gwt-RPC?

  - by guaz

  Dear all, I want draw a chart based on the date retrieve from the database by using RPC. But everytime I fail to get the result. My rpc function is working. I think is the sequence of the process. below is my class: public class TrafficPattern_1 extends GChart { TrafficPattern_1() { final DBServiceAsync dbService = GWT .create(DBService.class); dbService.SendData(null, null, new AsyncCallback<Container_TrafficPattern>() { @Override public void onFailure(Throwable caught) { } @Override public void onSuccess(Container_TrafficPattern result) { // TODO Auto-generated method stub pContainer.SetaDate(result.aDate.get(1)); } }); pContainer.aDate.get(0); setChartSize(350, 200); setChartTitle("<h2>Temperature vs Time<h2>"); setPadding("8px"); //setPixelSize(380, 200); getXAxis().setAxisLabel("<small><b><i>Time</i></b></small>"); getXAxis().setHasGridlines(true); getXAxis().setTickCount(6); // Except for "=(Date)", a standard GWT DateTimeFormat string getXAxis().setTickLabelFormat("=(Date)h:mm a"); getYAxis().setAxisLabel("<small><b><i>&deg;C</i></b></small>"); getYAxis().setHasGridlines(true); getYAxis().setTickCount(11); getYAxis().setAxisMin(11); getYAxis().setAxisMax(16); addCurve(); getCurve().setLegendLabel("<i> </i>"); getCurve().getSymbol().setBorderColor("blue"); getCurve().getSymbol().setBackgroundColor("blue"); // getCurve().getSymbol().setFillSpacing(10); // getCurve().getSymbol().setFillThickness(3); getCurve().getSymbol().setSymbolType(SymbolType.LINE); getCurve().getSymbol().setFillThickness(2); getCurve().getSymbol().setFillSpacing(1); for (int i = 0; i < dateSequence.length; i++) // Note that getTime() returns milliseconds since // 1/1/70--required whenever "date cast" tick label // formats (those beginning with "=(Date)") are used. getCurve().addPoint(dateSequence[i].date.getTime(), dateSequence[i].value); }

• How to use GWT when downloading Files with a Servlet?

  - by molleman

  Hello Guys I am creating a simple project that will allow me to upload and download files using gwt. i am having trouble with the downloading of files that are on my server. For the file upload i used http://code.google.com/p/gwtupload/ and followed the instructions there. My file is stored on the server outside of the website container(on the hard drive), Now when it comes to the downloading of a file, i want a user to press a download button and whatever item is currently selected will download. i dont really know how this will be done i know i need a download servlet public class DownloadAttachmentServlet extends HttpServlet { @Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // TODO Auto-generated method stub super.doGet(req, resp); } @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { String fileName = (String) req.getSession().getAttribute("fileName"); YFUser user = (YFUser) req.getSession().getAttribute(TestServiceImpl.SESSION_USER); if (user == null) throw new ServletException("Invalid Session"); InputStream in = null; OutputStream out = resp.getOutputStream(); FileInputStream fIn = new FileInputStream(fileName); byte[] buffer = new byte[4096]; int length; while ((length = in.read(buffer)) > 0){ out.write(buffer, 0, length); } in.close(); out.flush(); } } for the moment i will just pass a fileName string to retrieve the file for testing now i am lost at what to do on the client side, i have a simple public class DownloadFilePanel extends Composite { public DownloadFilePanel(final YFUser user , final String fileName){ final Element downloadIframe = RootPanel.get("__download").getElement(); VerticalPanel content = new VerticalPanel(); content.add(new Label("Download For this File : " + fileName)); Button button = new Button("Download"); button.addClickHandler(new ClickHandler(){ @Override public void onClick(ClickEvent event) { // i do not know what to do here }); content.add(button); initWidget(content); } } above is a simple widget that will supply a panel that will allow for the download of a file based on a fileName as you can see above, i do not know what to do to be able to download the file is there any one that can point me in the right direction?

• Why does the proxy generated code create the wrong class namespace when a MessageContract is in my W

  - by DaleyKD

  I have created two WCF Services (Shipping & PDFGenerator). They both, along with my ClientApp, share an assembly named Kyle.Common.Contracts. Within this assembly, I have three classes: namespace Kyle.Common.Contracts { [MessageContract] public class PDFResponse { [MessageHeader] public string fileName { get; set; } [MessageBodyMember] public System.IO.Stream fileStream { get; set; } } [MessageContract] public class PDFRequest { [MessageHeader] public Enums.PDFDocumentNameEnum docType { get; set; } [MessageHeader] public int? pk { get; set; } [MessageHeader] public string[] emailAddress { get; set; } [MessageBodyMember] public Kyle.Common.Contracts.TrackItResult[] trackItResults { get; set; } } [DataContract(Name = "TrackResult", Namespace = "http://kyle")] public class TrackResult { [DataMember] public int SeqNum { get; set; } [DataMember] public int ShipmentID { get; set; } [DataMember] public string StoreNum { get; set; } } } My PDFGenerator ServiceContract looks like: namespace Kyle.WCF.PDFDocs { [ServiceContract(Namespace="http://kyle")] public interface IPDFDocsService { [OperationContract] PDFResponse GeneratePDF(PDFRequest request); [OperationContract] void GeneratePDFAsync(Kyle.Common.Contracts.Enums.PDFDocumentNameEnum docType, int? pk, string[] emailAddress); [OperationContract] Kyle.Common.Contracts.TrackResult[] Test(); } } If I comment out the GeneratePDF stub, the proxy generated by VS2010 realizes that Test returns an array of Kyle.Common.Contracts.TrackResult. However, if I leave GeneratePDF there, the proxy refuses to use Kyle.Common.Contracts.TrackResult, and instead creates a new class, ClientApp.PDFDocServices.TrackResult, and uses that as the return type of Test. Is there a way to force the proxy generator to use Kyle.Common.Contracts.TrackResult whenever I use a MessageContract? Perhaps there's a better method for using a Stream and File Name as return types? I just don't want to have to create a Copy method to copy from ClientApp.PDFDocServices.TrackResult to Kyle.Common.Contracts.TrackResult, since they should be the exact same class. Thanks in advance, Kyle

• Bluetooth connect to a RS232 adapter in android

  - by ThePosey

  Hello All, I am trying to use the Bluetooth Chat sample API app that google provides to connect to a bluetooth RS232 adapter hooked up to another device. Here is the app for reference: http://developer.android.com/resources/samples/BluetoothChat/index.html And here is the spec sheet for the RS232 connector just for reference: http://serialio.com/download/Docs/BlueSnap-guide-4.77%5FCommands.pdf Well the problem is that when I go to connect to the device with: mmSocket.connect(); (BluetoothSocket::connect()) I always get an IOException error thrown by the connect method. When I do a toString on the exception I get "Service discovery failed". My question is mostly what are the cases that would cause an IOException to get thrown in the connect method? I know those are in the source somewhere but I don't know exactly how the java layer that you write apps in and the C/C++ layer that contains the actual stacks interface. I know that it uses the bluez bluetooth stack which is written in C/C++ but not sure how that ties into the java layer which is what I would think is throwing the exception. Any help on pointing me to where I can try to dissect this issue would be incredible. Also just to note I am able to pair with the RS232 adapter just fine but I am never able to actually connect. Here is the logcat output for more reference: I/ActivityManager( 1018): Displayed activity com.example.android.BluetoothChat/.DeviceListActivity: 326 ms (total 326 ms) E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) D/BluetoothChat( 1729): onActivityResult -1 D/BluetoothChatService( 1729): connect to: 00:06:66:03:0C:51 D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_CONNECTING E/BluetoothChat( 1729): + ON RESUME + I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_CONNECTING I/BluetoothChatService( 1729): BEGIN mConnectThread E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 I/BluetoothChatService( 1729): CONNECTION FAIL TOSTRING: java.io.IOException: Service discovery failed D/BluetoothChatService( 1729): setState() STATE_CONNECTING - STATE_LISTEN D/BluetoothChatService( 1729): start D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_LISTEN I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID I/NotificationService( 1018): enqueueToast pkg=com.example.android.BluetoothChat callback=android.app.ITransientNotification$Stub$Proxy@446327c8 duration=0 I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID The device I'm trying to connect to is the 00:06:66:03:0C:51 which I can scan for and apparently pair with just fine.

• Blackberry Development, adding dynamic number of buttons and setting Fieldchangelistener() for them

  - by Nikesh Yadav

  Hi, I am adding dynamic number of buttons in a Blackberry application and trying to get different events on each button click. I am not able to apply the setchangelistener() for these array of buttons as once the loop finishes after adding all the buttons, the events gets generated only for the last indexed button. If I make us of getIndex(), it runs fine only if I am not adding any other fields on my screen, but if I add other fields along with these array of buttons, the getIndex() function count them in the indexing as well. Can anyone please help me out in setting FieldChangeListener to array of ButtonField? Here is a sample code of the way I am using the array of ButtonField. I the code I have added two test LabelField at the top of the screen, if I remove them the code will run fine and I will get different result for each button click, but if I keep them active, the indexing gets effected and the Button wont work. package buttonclickloop; import net.rim.device.api.ui.DrawStyle; import net.rim.device.api.ui.Field; import net.rim.device.api.ui.FieldChangeListener; import net.rim.device.api.ui.component.ButtonField; import net.rim.device.api.ui.component.LabelField; import net.rim.device.api.ui.container.HorizontalFieldManager; import net.rim.device.api.ui.container.MainScreen; public class ButtoncClickLoop extends MainScreen { int i = 0; private ButtonField[] btn = new ButtonField[50]; public ButtoncClickLoop() { // TODO Auto-generated constructor stub LabelField Field1 = new LabelField("Field1"); LabelField Field2 = new LabelField("Field2",DrawStyle.RIGHT | ButtonField.USE_ALL_WIDTH); HorizontalFieldManager FieldHmgr = new HorizontalFieldManager(); FieldHmgr.add(Field1); FieldHmgr.add(Field2); FieldHmgr.setMargin(0,0,10,5); add(FieldHmgr); while (i < 3){ FieldChangeListener listener = new FieldChangeListener() { public void fieldChanged(Field field, int context) { context = field.getIndex(); if (field == btn[context]){ add(new LabelField("Label" + context + "")); } } }; btn[i] = new ButtonField("Button" + i + ""); btn[i].setChangeListener(listener); add(btn[i]); i = i + 1; } } } Thanks, Nikesh

• read user Input of custom dialogs

  - by urobo

  I built a custom dialog starting from an AlertDialog to obtain login information from a user. So the dialog contains two EditText fields, using the layoutinflater service I obtain the layout and I'm saving a reference to the fields. LayoutInflater inflater = (LayoutInflater) Home.this.getSystemService(LAYOUT_INFLATER_SERVICE); layoutLogin = inflater.inflate(R.layout.login,(ViewGroup) findViewById(R.id.rl)); usernameInput =((EditText)findViewById(R.id.getNewUsername)); passwordInput = ((EditText)findViewById(R.id.getNewPassword)); Then I have my overridden onCreateDialog(...) : { AlertDialog d = null; AlertDialog.Builder builder = new AlertDialog.Builder(this); switch(id){ ... case Home.DIALOG_LOGIN: builder.setView(layoutLogin); builder.setMessage("Sign in to your DyCaPo Account").setCancelable(false); d=builder.create(); d.setTitle("Login"); Message msg = new Message(); msg.setTarget(Home.this.handleLogin); Bundle data = new Bundle(); data.putString("username", usernameInput.getText().toString());// <---null pointer Exception data.putString("password", passwordInput.getText().toString()); msg.setData(data); d.setButton(Dialog.BUTTON_NEUTRAL,"Sign in",msg); break; ... return d; } and the handler set in the Message: private Handler handleLogin= new Handler(){ /* (non-Javadoc) * @see android.os.Handler#handleMessage(android.os.Message) */ @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub Log.d("Message Received", msg.getData().getString("username")+ msg.getData().getString("password")); } }; which for now works as a debugging tool. That's all. The Question is: what am I doing wrong? Because when I reach the line highlighted in the code ( the line in which I read the fields in the dialog ) I always get a null pointer exception. Could somebody please tell me the reason why it is so? And give some guidelines to work with dialogs. Thanks in advance!

• launching mapview from main activity (button)

  - by arc

  Hi all. Going round in circles here i think. I have an activity called Locate; public class Locate extends Activity { public static String lat; public static String lon; public static String number; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.locate); final Button buttonMaps = (Button) findViewById(R.id.ButtonMaps); buttonMaps.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); try { Intent i = new Intent(getBaseContext(), displayMap.class); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(i); } catch (ActivityNotFoundException e) { Toast.makeText(getBaseContext(), "Activity Not Found", Toast.LENGTH_SHORT).show(); } }}); // Toast.makeText(getBaseContext(), "lat: " + lat + " long: " + lon + " from: " + testname, Toast.LENGTH_LONG).show(); } If I make the displayMap class into a normal Activity, and just have display a toast message confirming it has loaded - then it works fine. If i do this though; public class displayMap extends MapActivity { /** Called when the activity is first created. */ public void onCreate() { setContentView(R.layout.displaymap); Toast.makeText(getBaseContext(), "Display Map", Toast.LENGTH_SHORT).show(); } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } } Then as soon as I click the Button, I get a force close. I have the correct 'uses-library' tag in my manifest; <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="com.google.android.maps" /> I don't get what it just force closes everytime i try and load it. If I make this my onClick handler then it will fire up a working googlemaps/default mapview public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); Uri uri=Uri.parse("geo:"+Locate.lat+","+Locate.lon); StartActivity(new Intent(Intent.ACTION_VIEW, uri)); } But that is not what I am trying to do, I want my own - so that I can add overlays etc to it. But it does prove that the permission are set correctly and that the lib is there. The logcat error when the app FCs is a Unexpected DEX error. Can anyone point in the right direction here?

  Hi friends! In my application I tried to search diff map location using diff lat and long. First time the application show the map but wen i change the lat long and try to invalidate the mapview using diff lat long, map is not refreshed.

What could be causing this?

• Unit finalization order for application, compiled with run-time packages?

  - by Alexander

  I need to execute my code after finalization of SysUtils unit. I've placed my code in separate unit and included it first in uses clause of dpr-file, like this: project Project1; uses MyUnit, // <- my separate unit SysUtils, Classes, SomeOtherUnits; procedure Test; begin // end; begin SetProc(Test); end. MyUnit looks like this: unit MyUnit; interface procedure SetProc(AProc: TProcedure); implementation var Test: TProcedure; procedure SetProc(AProc: TProcedure); begin Test := AProc; end; initialization finalization Test; end. Note that MyUnit doesn't have any uses. This is usual Windows exe, no console, without forms and compiled with default run-time packages. MyUnit is not part of any package (but I've tried to use it from package too). I expect that finalization section of MyUnit will be executed after finalization section of SysUtils. This is what Delphi's help tells me. However, this is not always the case. I have 2 test apps, which differs a bit by code in Test routine/dpr-file and units, listed in uses. MyUnit, however, is listed first in all cases. One application is run as expected: Halt0 - FinalizeUnits - ...other units... - SysUtils's finalization - MyUnit's finalization - ...other units... But the second is not. MyUnit's finalization is invoked before SysUtils's finalization. The actual call chain looks like this: Halt0 - FinalizeUnits - ...other units... - SysUtils's finalization (skipped) - MyUnit's finalization - ...other units... - SysUtils's finalization (executed) Both projects have very similar settings. I tried a lot to remove/minimize their differences, but I still do not see a reason for this behaviour. I've tried to debug this and found out that: it seems that every unit have some kind of reference counting. And it seems that InitTable contains multiply references to the same unit. When SysUtils's finalization section is called first time - it change reference counter and do nothing. Then MyUnit's finalization is executed. And then SysUtils is called again, but this time ref-count reaches zero and finalization section is executed: Finalization: // SysUtils' finalization 5003B3F0 55 push ebp // here and below is some form of stub 5003B3F1 8BEC mov ebp,esp 5003B3F3 33C0 xor eax,eax 5003B3F5 55 push ebp 5003B3F6 688EB50350 push $5003b58e 5003B3FB 64FF30 push dword ptr fs:[eax] 5003B3FE 648920 mov fs:[eax],esp 5003B401 FF05DCAD1150 inc dword ptr [$5011addc] // here: some sort of reference counter 5003B407 0F8573010000 jnz $5003b580 // <- this jump skips execution of finalization for first call 5003B40D B8CC4D0350 mov eax,$50034dcc // here and below is actual SysUtils' finalization section ... Can anyone can shred light on this issue? Am I missing something?

• Spring/RMI server error

  - by 4herpsand7derpsago

  We have a Spring MVC web app (WAR) deploying to Tomcat (6.0.35) that launches a thread inside a separate JVM at deploy time (don't ask why - not my design) and then communicates with that thread via RMI over port 8888. Despite being totally convoluded, this was working perfectly fine up until yesterday, and now the thread is failing at startup and despite our best efforts to add logging into the mix, we are hitting a wall. This is the only exception we are able to find in the logs: Jun 12, 2012 3:11:36 AM com.ourapp.ImageController destroy SEVERE: Shutdown Error: Lookup of RMI stub failed; nested exception is java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: java.net.ConnectException: Connection refused Jun 12, 2012 3:11:37 AM org.apache.catalina.core.StandardContext listenerStop SEVERE: Exception sending context destroyed event to listener instance of class org.springframework.web.context.ContextLoaderListener java.lang.NoClassDefFoundError: org/springframework/web/context/ContextCleanupListener at org.springframework.web.context.ContextLoaderListener.contextDestroyed(ContextLoaderListener.java:80) at org.apache.catalina.core.StandardContext.listenerStop(StandardContext.java:3973) at org.apache.catalina.core.StandardContext.stop(StandardContext.java:4577) at org.apache.catalina.startup.HostConfig.checkResources(HostConfig.java:1165) at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1271) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:296) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1337) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1601) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1610) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1590) at java.lang.Thread.run(Thread.java:662) Caused by: java.lang.ClassNotFoundException: org.springframework.web.context.ContextCleanupListener at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233) ... 12 more The ImageController is the Spring MVC Controller that is responsible for kicking off this daemon/spawned RMI thread. Based on the verbage of this error, does anybody have any idea what might be causing this "connection refused" error? Running a netstat -an | grep 8888 (this is a Linux machine) produces no output which means nothing is listening on that port. Thanks in advance for any ideas/suggestions that lead to a fix.

• Copy android.R.layout to my project

  - by eric

  Good advice from CommonWare and Steve H but it's not as easy to me as I first thought. Based on their advice I'm trying to copy android.R.layout to my project to ensure consistency. How do you do this? I looked in Eclipse's Package Explorer and under Android 1.5android.jarandroidR.classRlayout and find R$layout.class. Do I copy the code out of there into my own class? From my very limited knowledge of Java, the following code doesn't make much sense: public static final class android.R$layout { // Field descriptor #8 I public static final int activity_list_item = 17367040; // Field descriptor #8 I public static final int browser_link_context_header = 17367054; // Field descriptor #8 I public static final int expandable_list_content = 17367041; // Field descriptor #8 I public static final int preference_category = 17367042; // Field descriptor #8 I public static final int select_dialog_item = 17367057; // Field descriptor #8 I public static final int select_dialog_multichoice = 17367059; // Field descriptor #8 I public static final int select_dialog_singlechoice = 17367058; // Field descriptor #8 I public static final int simple_dropdown_item_1line = 17367050; // Field descriptor #8 I public static final int simple_expandable_list_item_1 = 17367046; // Field descriptor #8 I public static final int simple_expandable_list_item_2 = 17367047; // Field descriptor #8 I public static final int simple_gallery_item = 17367051; // Field descriptor #8 I public static final int simple_list_item_1 = 17367043; // Field descriptor #8 I public static final int simple_list_item_2 = 17367044; // Field descriptor #8 I public static final int simple_list_item_checked = 17367045; // Field descriptor #8 I public static final int simple_list_item_multiple_choice = 17367056; // Field descriptor #8 I public static final int simple_list_item_single_choice = 17367055; // Field descriptor #8 I public static final int simple_spinner_dropdown_item = 17367049; // Field descriptor #8 I public static final int simple_spinner_item = 17367048; // Field descriptor #8 I public static final int test_list_item = 17367052; // Field descriptor #8 I public static final int two_line_list_item = 17367053; // Method descriptor #50 ()V // Stack: 3, Locals: 1 public R$layout(); 0 aload_0 [this] 1 invokespecial java.lang.Object() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc <String "Stub!"> [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 899] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: android.R.layout Inner classes: [inner class info: #5 android/R$layout, outer class info: #64 android/R inner name: #55 layout, accessflags: 25 public static final] }

• Some frames are not showing in Frame Animation

  - by Aju Vidyadharan

  I am doing a frame to frame animation. My problem is I have given around 10 drawable images in my anim xml. But only first two and last two is showing not all the images. I am doing a translation also on this image.After translation only frame animation starts.Translation is happening and frame animation also happening but it is not showing all the frames. Here is my anim xml. only frog_01 and frog_02 is showing. <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="true" > <item android:drawable="@drawable/frog_01" android:duration="70"/> <item android:drawable="@drawable/frog_02" android:duration="70"/> <item android:drawable="@drawable/frog_03" android:duration="70"/> <item android:drawable="@drawable/frog_04" android:duration="70"/> <item android:drawable="@drawable/frog_05" android:duration="70"/> <item android:drawable="@drawable/frog_04" android:duration="70"/> <item android:drawable="@drawable/frog_03" android:duration="70"/> <item android:drawable="@drawable/frog_02" android:duration="70"/> <item android:drawable="@drawable/frog_01" android:duration="70"/> </animation-list> Here is the code which I am using for the translation and Frame animation... public void frogAnim() { frogView.clearAnimation(); final TranslateAnimation fslide2 = new TranslateAnimation(10, 65, 0, 0); fslide2.setDuration(400); fslide2.setFillAfter(true); fslide2.setAnimationListener(fanimationListener1); frogView.startAnimation(fslide2); c = false; } AnimationListener fanimationListener1 = new AnimationListener() { public void onAnimationEnd(Animation arg0) { c = true; frogView.setBackgroundResource(R.drawable.frog_movement); frogFrameAnimation = (AnimationDrawable) frogView.getBackground(); frogFrameAnimation.start(); playAudioFileListener(R.raw.frog, player); CountDownTimer count = new CountDownTimer(200, 700) { @Override public void onTick(long millisUntilFinished) { } @Override public void onFinish() { frogFrameAnimation.stop(); titileAnimMusic(R.drawable.frog_title, R.anim.alpha_fade_in1, R.raw.vo_child_frog, player); } }; count.start(); } public void onAnimationRepeat(Animation animation) { // TODO Auto-generated method stub } public void onAnimationStart(Animation animation) { } };

• Exception in thread "main" java.lang.StackOverflowError

  - by Ray.R.Chua

  I have a piece of code and I could not figure out why it is giving me Exception in thread "main" java.lang.StackOverflowError. This is the question: Given a positive integer n, prints out the sum of the lengths of the Syracuse sequence starting in the range of 1 to n inclusive. So, for example, the call: lengths(3) will return the the combined length of the sequences: 1 2 1 3 10 5 16 8 4 2 1 which is the value: 11. lengths must throw an IllegalArgumentException if its input value is less than one. My Code: import java.util.HashMap; public class Test { HashMap<Integer,Integer> syraSumHashTable = new HashMap<Integer,Integer>(); public Test(){ } public int lengths(int n)throws IllegalArgumentException{ int sum =0; if(n < 1){ throw new IllegalArgumentException("Error!! Invalid Input!"); } else{ for(int i =1; i<=n;i++){ if(syraSumHashTable.get(i)==null) { syraSumHashTable.put(i, printSyra(i,1)); sum += (Integer)syraSumHashTable.get(i); } else{ sum += (Integer)syraSumHashTable.get(i); } } return sum; } } private int printSyra(int num, int count){ int n = num; if(n == 1){ return count; } else{ if(n%2==0){ return printSyra(n/2, ++count); } else{ return printSyra((n*3)+1, ++count) ; } } } } Driver code: public static void main(String[] args) { // TODO Auto-generated method stub Test s1 = new Test(); System.out.println(s1.lengths(90090249)); //System.out.println(s1.lengths(5)); } . I know the problem lies with the recursion. The error does not occur if the input is a small value, example: 5. But when the number is huge, like 90090249, I got the Exception in thread "main" java.lang.StackOverflowError. Thanks all for your help. :) I almost forgot the error msg: Exception in thread "main" java.lang.StackOverflowError at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:65) at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:65) at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:60)
