• "rsAccessDenied" error for SSRS 2008

  - by JackLocke

  Hi All, I have been trying to access SSRS Web Service URL hxxp://myServer:80/ReportServer (from Reporting Service Configuration Manager), but my IE always shows "rsAccessDenied" message saying that my account doesn't have privilage required to view. Here are my system specs. Its my laptop with Windows 7 x64, and SQL Server 2008 with SP1 and I am using Mixed Mode Authentication with My account as SysAdmin privilages and this is what I have been trying / tried ... (ofcourse with restarting the service everytime I make any change in configuration), I changed service account from Reporting Service Configuration Manager to make it use My account but nothing happend. I tried running my IE as admin, by RUN AS ADMIN but still same message. Then I read somewhere I have to delete/recreate my encryption keys as well, so I tried again with that, then it was asking me to enter ID/PWD to access server here I am totally blank because it was not accepting my account credentials !!!. Weird thing is I can see my existing reports if I follow this URL hxxp://myServer:80/Reports , for which My guess is solely used to view reports. I have read post here about kind of same problem, but it seems that OP just left forum after asking question... Also, MSDN does have these helps hxxp://msdn.microsoft.com/en-us/library/ms156034.aspx hxxp://msdn.microsoft.com/en-us/library/bb630430.aspx but both of this didn't workout for me. I will really appriciate it if any one can help me out. Jack p.s. I was not allowed to post more than 1 URL because of my "reputation" so I had to change the string a bit. Please replace hxxp wih http in URLs.

• question about jQuery droppable/draggable.

  - by FALCONSEYE

  I modified a sample photo manager application. photo manager application Instead of photos, I have employee records coming from a query. My version will let managers mark employees as on vacation, or at work. One of the things I did is to include employee ids like <a href="123">. I get the ids from event.target. This works for the click function but not for the "droppable" function. This is what I have for the click function: $('ul.gallery > li').click(function(ev) { var $item = $(this); var $unid = ev.target; var $target = $(ev.target); if ($target.is('a.ui-icon-suitcase')) { deleteImage($item,$unid); } else if ($target.is('a.ui-icon-arrowreturnthick-1-w')) { recycleImage($item,$unid); } return false; }); ev.target correctly gives the employee id. when i try the same in one of the droppable functions: $gallery.droppable({ accept: '#suitcase li', activeClass: 'custom-state-active', drop: function(ev, ui) { var $unid = ev.target; alert($unid); recycleImage(ui.draggable,$unid); } }); the alert(ui) gives me [object]. What's in this object? How do i get the href out of this? thanks

• A feeling that I'm not that good developer

  - by Karim

  Hi, Im having a strange feeling, but let me first introduce myself as a software developer. I started to program when I was still a kid, I had about 10 or 11 years. I really enjoy my work and never get bored from it. It's amazing how somebody could be paid for what he really likes to do and would be doing it anyway even for free. WHen I first started to program, I was feeling proud of what I was doing, each application I built was for me a success and after 2-3 year I had a feeling that I'm a coding guru. It was a nice feeling ;-) But the more I was in the field, the more types of software I started to develop I was starting to have a feeling that I'm completely wrong in that I'm guru. I felt that I'm not even a mediocre developer. Each new field I start to work on is giving me this feeling. Like when I once developed a device driver for a client, I saw how much I need to learn about device drivers. When I developed a video filter for an application, I saw how much do I still need to learn about DirectShow, Color Spaces, and all the theory behind that. The worst thing was when I started to learn algorithms. It was several years ago. I knew then the basic structures and algorithms like the sorting, some types of trees, some hashtables, strings etc.. and when I really wanted to learn a group of structures I learned about 5-6 new types and saw that in fact even this small group has several hundred subtypes of structures. It's depressing how little time people have in their lives to learn all this stuff. I'm now a software developer with about 10 years of experience and I still feel that I'm not a proficient developer when I think about things that others do in the industry. Is this normal what I'm experiencing or is it a sign of a destructive excessive ambition? Thanks in advance for any comments.

• Memory efficient collection class

  - by Joe

  I'm building an array of dictionaries (called keys) in my iphone application to hold the section names and row counts for a tableview. the code looks like this: [self.results removeAllObjects]; [self.keys removeAllObjects]; NSUInteger i,j = 0; NSString *key = [NSString string]; NSString *prevKey = [NSString string]; if ([self.allResults count] > 0) { prevKey = [NSString stringWithString:[[[self.allResults objectAtIndex:0] valueForKey:@"name"] substringToIndex:1]]; for (NSDictionary *theDict in self.allResults) { key = [NSString stringWithString:[[theDict valueForKey:@"name"] substringToIndex:1]]; if (![key isEqualToString:prevKey]) { NSDictionary *newDictionary = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:i],@"count", prevKey,@"section", [NSNumber numberWithInt:j], @"total",nil]; [self.keys addObject:newDictionary]; prevKey = [NSString stringWithString:key]; i = 1; } else { i++; } j++; } NSDictionary *newDictionary = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:i],@"count", prevKey,@"section", [NSNumber numberWithInt:j], @"total",nil]; [self.keys addObject:newDictionary]; } [self.tableview reloadData]; The code works fine first time through but I sometimes have to rebuild the entire table so I redo this code which orks fine on the simulator, but on my device the program bombs when I execute the reloadData line : malloc: *** mmap(size=3772944384) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug malloc: *** mmap(size=3772944384) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug Program received signal: “EXC_BAD_ACCESS”. If I remove the reloadData line the code works on the device. I'm wondering if this is something to do with the way I've built the keys array (ie using autoreleased strings and dictionaries).

• iPodMusicPlayer playbackState inaccurate after odd conditions

  - by Shane Costello

  I have a simple music player app that runs into a really weird problem. First of all, while playing music and in the locked state, I allow the user to double click the Home button and use the locked iPod music controls. I did notice however that while in the locked state, my app doesn't receive any of its registered notifications. For the most part, this is fine anyway. But, if the user is playing music for at least 15 minutes (I'm not sure why but any less and this problem doesn't occur) while in the locked state, and using some kind of headphone or aux jack, then unplugs the headphone/aux jack while the device is still playing music, the iPodMusicPlayer will auto-pause. Which is exactly what I would want it to do, but after this happens, when the user unlocks their device and gives focus to the app again, the iPodMusicPlayer's playbackState is inaccurate. - (IBAction)playPause:(id)sender { if ([musicPlayer playbackState] == MPMusicPlaybackStatePlaying) { [musicPlayer pause]; } else { [musicPlayer play]; } } where musicPlayer = [MPMusicPlayerController iPodMusicPlayer]. Under normal circumstances, this runs perfectly fine. But after these conditions, my breakpoint will hit the condition for MPMusicPlaybackStatePlaying while the music is paused, and vice versa. The only way I've been able to fix this is to either make a new selection of music or to terminate the app and reopen. I've tried tons of a workarounds to fix this problem programmatically, but nothing turns out a 100% bug free fix. Does anyone have any clue as to why this happens in the first place?

• Should a developer be a coauthor to a paper presented about the application they developed?

  - by ved

  In our organization, project teams come up with a need and funding and developers are given a basic scope and are allowed to develop the solution. There is a certain degree of implementation freedom given to the developers. They drive the solution to pilot and live deployment from its inception. If the solution is presented in a conference as a technical paper/white paper what is the protocol for the list of authors: because for the most part I see the project manager's and the dev team manager's names as authors but no mention of the actual developer. Is this correct? A lot of us developers feel pretty bummed to never see our names as the coauthors. Appreciate any pointers. Answers to the FOLLOW UP questions (1) in what field of study is the paper, and what are the standards of authorship for that field? The paper is for Flood Plain Management - there is nothing on the abstract guidelines, I have called the contact person listed for comment - waiting to hear. 2) was the paper literally about the software application as your question implies, or were the software issues incidental to the topic of the paper? The paper specifically deals with a GIS Application that is used in Coastal Engineering, yes the software is not incidental, but the meat of the paper and mentioned in the Title. 2

• How to wait until location is completely found? (Core Location)

  - by sudo rm -rf

  Hello. I have a problem within my app. I'm trying to find the user's location to the best preciseness in order to determine their zip-code. Currently I have a button that, when pressed, starts a method named locateMe. -(IBAction)locateMe; { self.locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; [locationManager startUpdatingLocation]; Then I've implemented didUpdateToLocation: -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation; { NSLog(@"Found location! %f,%f",newLocation.coordinate.latitude,newLocation.coordinate.longitude); } I had previously done much more complicated stuff in didUpdateToLocation but as I tested some things I realized that the first location it found was not precise in the least. So, I put the NSLog call in there and it gave me an output similar to below... Found location! 39.594093,-98.614834 Found location! 39.601372,-98.592171 Found location! 39.601372,-98.592171 Found location! 39.611444,-98.538196 Found location! 39.611444,-98.538196 As you can see, it first gives me a value which is not correct, which was causing problems within my app because it wasn't giving the correct location. So, here's my question. Is there any way I can wait for the location manager to finish finding the most precise location? Thanks in advance! EDIT: I'm wanting something like this: if (newLocation.horizontalAccuracy <= locationManager.desiredAccuracy) { } But it never gets called!

• socket timeout and remove O_NONBLOCK option

  - by juxstapose

  Hello, I implemented a socket timeout and retry but in order to do it I had to set the socket as a non-blocking socket. However, I need the socket to block. This was my attempt at a solution to these two problems. This is not working. Subsequent send calls block but never send any data. When I connect without the select and the timeout, subsequent send calls work normally. References: C: socket connection timeout How to reset a socket back to blocking mode (after I set it to nonblocking mode)? Code: fd_set fdset; struct timeval tv; fcntl(dsock, F_SETFL, O_NONBLOCK); tv.tv_sec = theDeviceTimeout; tv.tv_usec = 0; int retries=0; logi(theLogOutput, LOG_INFO, "connecting to device socket num retrys: %i", theDeviceRetry); for(retries=0;retries<theDeviceRetry;retries++) { connect(dsock, (struct sockaddr *)&daddr, sizeof daddr); FD_ZERO(&fdset); FD_SET(dsock, &fdset); if (select(dsock + 1, NULL, &fdset, NULL, &tv) == 1) { int so_error; socklen_t slen = sizeof so_error; getsockopt(dsock, SOL_SOCKET, SO_ERROR, &so_error, &slen); if (so_error == 0) { logi(theLogOutput, LOG_INFO, "connected to socket on port %i on %s", theDevicePort, theDeviceIP); break; } else { logi(theLogOutput, LOG_WARN, "connect to %i failed on ip %s because %s retries %i", theDevicePort, theDeviceIP, strerror(errno), retries); logi(theLogOutput, LOG_WARN, "failed to connect to device %s", strerror(errno)); logi(theLogOutput, LOG_WARN, "error: %i %s", so_error, strerror(so_error)); continue; } } } int opts; opts = fcntl(dsock,F_GETFL); logi(theLogOutput, LOG_DEBUG, "clearing nonblock option %i retries %i", opts, retries); opts ^= O_NONBLOCK; fcntl(dsock, F_SETFL, opts);

• Force windows video driver reload. Is it possible at all?

  - by somemorebytes

  Hi there, Some drivers use parameters written in the registry to configure themselves when they get loaded at boot time. I can modify those values and then reboot, but I would like to know if it is possible to force the driver reload, making the changes effective without rebooting. Specifically, I am talking about the video driver (nvidia). I read somewhere, that calling through pINvoke() [User32.ll]::ChangeDisplaySettings() with a 640x480x8bits resolution,(which is so low that it should not be supported by a modern driver) will force windows to load the "Standard VGA driver", and making another call with the current resolution will load the nvidia driver again. This does not work though. At least in Windows 7, even if the low res is not displayed as "supported" the system reduces the screen to a little square in the center of the screen, showing the low res wihtout unloading the nvidia driver. So, is there any .NET/Win32 API, service to restart, or any way at all to force a video driver reload? Perhaps programatically disabling the device (as you could do from the Device Manager) and reenabling it again? Any idea? Thanks a lot.

• How to close InAppBrowser itself in Phonegap Application?

  - by Shashi

  I am developing Phonegap application and currently i am using InAppBrowser to display external pages. On some of the external pages I place a close button and i want to close the InAppBrowser itself. because InAppBrowser displays these pages that is why the reference of it is not accessed on itself to close it and Please do not suggest me to use ChildBrowser Plugin. window.close(); //Not Worked for me or iabRef.close(); //Also not Worked for me because iabRef is not accessible on InAppBrowser. It is created on Parent Window Some of the Android device and iOS device display a Done Button to close it. As well as the iPad also display the Done button. but in Case of Android tablet there is not any kind of button to close it. UPDATE :- Here is my full code :- var iabRef = null; function iabLoadStart(event) { } function iabLoadStop(event) { } function iabClose(event) { iabRef.removeEventListener('loadstart', iabLoadStart); iabRef.removeEventListener('loadstop', iabLoadStop); iabRef.removeEventListener('exit', iabClose); } function startInAppB() { var myURL=encodeURI('http://www.domain.com/some_path/mypage.html'); iabRef = window.open(myURL,'_blank', 'location=yes'); iabRef.addEventListener('loadstart', iabLoadStart); iabRef.addEventListener('loadstop', iabLoadStop); iabRef.addEventListener('exit', iabClose); }

• Where should an application's default folder live?

  - by HotOil

  Hi: I'm creating a little app that configures a connected device and then saves the config information in a file. The filename cannot be chosen by the user, but its location can be chosen. Where is the best place for the app's default save-to folder? I have seen examples out there where it is the "MyDocuments" location (eg Visual Studio does this). I have seen a folder created right at the top of the C:\ drive. I find that to be a little obnoxious, personally. It could be in the Program Files[Manufacturer] or Program Files[Product Name], or wherever the app was installed. I have used this location in the past; I dislike it because Windows Explorer does not allow a user to browse to there very easily ('browsability'). Going with this last notion that 'browsability' is a factor, I suppose MyDocuments is the best choice. Is this the most common, most widely accepted practice? I think historically we have chosen the install folder because that co-locates the data with the device management utilities. But I would really like to get away from that. I don't want the user to have to go pawing through system files to find his/her data, esp if that person is not too Windows-savvy. Also, I am using the .NET WinForms FolderBrowserDialog, and the "Environment.SpecialFolders" enum isn't helpful in setting up the dialog to point into the Program Files folder. Thanks for your input! Suz.

• What is the fastest way to do division in C for 8bit MCUs?

  - by Jordan S

  I am working on the firmware for a device that uses an 8bit mcu (8051 architecture). I am using SDCC (Small Device C Compiler). I have a function that I use to set the speed of a stepper motor that my circuit is driving. The speed is set by loading a desired value into the reload register for a timer. I have a variable, MotorSpeed that is in the range of 0 to 1200 which represents pulses per second to the motor. My function to convert MotorSpeed to the correct 16bit reload value is shown below. I know that float point operations are pretty slow and I am wondering if there is a faster way of doing this... void SetSpeed() { float t = MotorSpeed; unsigned int j = 0; t = 1/t ; t = t / 0.000001; j = MaxInt - t; TMR3RL = j; // Set reload register for desired freq return; }

• Issue with Callback method and maintaining CultureInfo and ASP.Net HttpRuntime

  - by Little Larry Sellers

  Hi All, Here is my issue. I am working on an E-commerce solution that is deployed to multiple European countries. We persist all exceptions within the application to SQL Server and I have found that there are records in the DB that have a DateTime in the future! We define the culture in the web.config, for example pt-PT, and the format expected is DD-MM-YYYY. After debugging I found the issue with these 'future' records in the DB is because of Callback methods we use. For example, in our Caching architecture we use Callbacks, as such - CacheItemRemovedCallback ReloadCallBack = new CacheItemRemovedCallback(OnRefreshRequest); When I check the current threads CultureInfo, on these Callbacks it is en-US instead of pt-PT and also the HttpContext is null. If an exception occurs on the Callback our exception manager reports it as MM-DD-YYYY and thus it is persisted to SQL Server incorrectly. Unfortunately, in the exception manager code, we use DateTime.Now, which is fine if it is not a callback. I can't change this code to be culture specific due to it being shared across other verticals. So, why don't callbacks into ASP.Net maintain context? Is there any way to maintain it on this callback thread? What are the best practices here? Thanks.

• Custom UITableView headerView disappears after memory warning

  - by psychotik

  I have a UITableViewController. I create a custom headerView for it's tableView in the loadView method like so: (void)loadView { [super loadView]; UIView* containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, height * 2 )]; containerView.tag = 'cont'; containerView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin; UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(padding, height, width, height); ... //configure UIButton and events UIImageView* imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"] highlightedImage:[UIImage imageNamed:@"highlight.png"]]; imageView.frame = CGRectMake(0, 0, width, height ); ... //configure UIImageView [containerView addSubview:button]; [containerView addSubview:imageView]; self.tableView.tableHeaderView = containerView; [imageView release]; [containerView release]; } None of the other methods (viewDidLoad/Unload, etc) are overloaded. This controller is hosted in a tab. When I switch to another tab and simulate a memory warning, and then come back to this tab, my UITableView is missing my custon header. All the rows/section are visible as I would expect. Putting a BP in the loadView code above, I see it being invoked when I switch back to the tab after the memory warning, and yet I can't actually see the header. Any ideas about what I'm missing here? EDIT: This happens on the device and the simulator. On the device, I just let a memory warning occur by opening a bunch of different apps while mine is in the background.

• Detect a USB drive being inserted - Windows Service

  - by Tom Bell

  I am trying to detect a USB disk drive being inserted within a Windows Service, I have done this as a normal Windows application. The problem is the following code doesn't work for volumes. Registering the device notification: DEV_BROADCAST_DEVICEINTERFACE notificationFilter; HDEVNOTIFY hDeviceNotify = NULL; ::ZeroMemory(&notificationFilter, sizeof(notificationFilter)); notificationFilter.dbcc_size = sizeof(DEV_BROADCAST_DEVICEINTERFACE); notificationFilter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE; notificationFilter.dbcc_classguid = ::GUID_DEVINTERFACE_VOLUME; hDeviceNotify = ::RegisterDeviceNotification(g_serviceStatusHandle, &notificationFilter, DEVICE_NOTIFY_SERVICE_HANDLE); The code from the ServiceControlHandlerEx function: case SERVICE_CONTROL_DEVICEEVENT: PDEV_BROADCAST_HDR pBroadcastHdr = (PDEV_BROADCAST_HDR)lpEventData; switch (dwEventType) { case DBT_DEVICEARRIVAL: ::MessageBox(NULL, "A Device has been plugged in.", "Pounce", MB_OK | MB_ICONINFORMATION); switch (pBroadcastHdr->dbch_devicetype) { case DBT_DEVTYP_DEVICEINTERFACE: PDEV_BROADCAST_DEVICEINTERFACE pDevInt = (PDEV_BROADCAST_DEVICEINTERFACE)pBroadcastHdr; if (::IsEqualGUID(pDevInt->dbcc_classguid, GUID_DEVINTERFACE_VOLUME)) { PDEV_BROADCAST_VOLUME pVol = (PDEV_BROADCAST_VOLUME)pDevInt; char szMsg[80]; char cDriveLetter = ::GetDriveLetter(pVol->dbcv_unitmask); ::wsprintfA(szMsg, "USB disk drive with the drive letter '%c:' has been inserted.", cDriveLetter); ::MessageBoxA(NULL, szMsg, "Pounce", MB_OK | MB_ICONINFORMATION); } } return NO_ERROR; } In a Windows application I am able to get the DBT_DEVTYP_VOLUME in dbch_devicetype, however this isn't present in a Windows Service implementation. Has anyone seen or heard of a solution to this problem, without the obvious, rewrite as a Windows application?

• Why does using the Asynchronous Programming Model in .Net not lead to StackOverflow exceptions?

  - by uriDium

  For example, we call BeginReceive and have the callback method that BeginReceive executes when it has completed. If that callback method once again calls BeginReceive in my mind it would be very similar to recursion. How is that this does not cause a stackoverflow exception. Example code from MSDN: private static void Receive(Socket client) { try { // Create the state object. StateObject state = new StateObject(); state.workSocket = client; // Begin receiving the data from the remote device. client.BeginReceive( state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state); } catch (Exception e) { Console.WriteLine(e.ToString()); } } private static void ReceiveCallback( IAsyncResult ar ) { try { // Retrieve the state object and the client socket // from the asynchronous state object. StateObject state = (StateObject) ar.AsyncState; Socket client = state.workSocket; // Read data from the remote device. int bytesRead = client.EndReceive(ar); if (bytesRead > 0) { // There might be more data, so store the data received so far. state.sb.Append(Encoding.ASCII.GetString(state.buffer,0,bytesRead)); // Get the rest of the data. client.BeginReceive(state.buffer,0,StateObject.BufferSize,0, new AsyncCallback(ReceiveCallback), state); } else { // All the data has arrived; put it in response. if (state.sb.Length > 1) { response = state.sb.ToString(); } // Signal that all bytes have been received. receiveDone.Set(); } } catch (Exception e) { Console.WriteLine(e.ToString()); } }

• Java: design for using many executors services and only few threads

  - by Guillaume

  I need to run in parallel multiple threads to perform some tests. My 'test engine' will have n tests to perform, each one doing k sub-tests. Each test result is stored for a later usage. So I have n*k processes that can be ran concurrently. I'm trying to figure how to use the java concurrent tools efficiently. Right now I have an executor service at test level and n executor service at sub test level. I create my list of Callables for the test level. Each test callable will then create another list of callables for the subtest level. When invoked a test callable will subsequently invoke all subtest callables test 1 subtest a1 subtest ...1 subtest k1 test n subtest a2 subtest ...2 subtest k2 call sequence: test manager create test 1 callable test1 callable create subtest a1 to k1 testn callable create subtest an to kn test manager invoke all test callables test1 callable invoke all subtest a1 to k1 testn callable invoke all subtest an to kn This is working fine, but I have a lot of new treads that are created. I can not share executor service since I need to call 'shutdown' on the executors. My idea to fix this problem is to provide the same fixed size thread pool to each executor service. Do you think it is a good design ? Do I miss something more appropriate/simple for doing this ?

• UDP server doesnt accept calls from outside.

  - by rayman

  Hi, ive implement simple udp server on my Android device.(sdk 1.5) it works fine when i am runnning a local client on the phone sends through it trigger to my server. but when i try to get udp call from an outside server to my phone, it doesnt work. already make sure the outside server isnt blocked by firewall and it's sending the udp trigger to the right port, which my phone is listening to. i used natstat on the phone and checked that the phone is realy listening to the it's local ip and the port ive setted it to. here is my code of the server:(on the device) // server will listen to one client try { Thread udpServerThread = new Thread() { @Override public void run() { try { // Retrieve the ServerName InetAddress serverAddr = InetAddress .getByName("localhost"); Log.d("UDP", "S: Connecting..."); // Create new UDP-Socket socket = new DatagramSocket(SERVERPORT,serverAddr); byte[] buf = new byte[17]; // * Prepare a UDP-Packet that can contain the data we // * want to receive DatagramPacket packet = new DatagramPacket(buf, buf.length); Log.d("UDP", "S: Receiving..."); // wait to Receive the UDP-Packet socket.receive(packet); Log.d("UDP", "S: Received: '" + new String(packet.getData()) + "'"); acceptedMsg=new String(packet.getData()); notifyService(acceptedMsg); Log.d("UDP", "S: Done."); } catch (Exception e) { Log.e("UDP", "S: Error", e); } } }; udpServerThread.start(); } catch (Exception E) { Log.e("r",E.getMessage()) ; } so as i said, when i try it with local client(seperate thread) which sends udp trigger it works fine, but when i take this client implementation and put it on an outside real server, after UDP being sent, the phone doesnt respond to it. any idea? thanks, ray.

  Hi, all. I saw this topic and implement IntentService as describes, but what if I want more that one button? How can I distinguish button from each other? I'm trying to setFlags, but cannot read it at onHandleIntent() method: public static class UpdateService extends IntentService { ... @Override public void onHandleIntent(Intent intent) { ComponentName me = new ComponentName(this, ExampleProvider.class); AppWidgetManager manager = AppWidgetManager.getInstance(this); manager.updateAppWidget(me, buildUpdate(this)); } private RemoteViews buildUpdate(Context context) { RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.main_layout); Intent i = new Intent(this, ExampleProvider.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); updateViews.setOnClickPendingIntent(R.id.button_refresh, pi); i = new Intent(this, ExampleProvider.class); pi = PendingIntent.getBroadcast(context, 0, i, 0); updateViews.setOnClickPendingIntent(R.id.button_about, pi); return updateViews; } } At this little piece of code I have two PendingIntent linked with setOnClickPendingIntent, can I distinguish this intent for different actions and processing?

  I have a listbox control where items are added using a user control having a textblock and image. <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" FontFamily="{StaticResource PhoneFontFamilyNormal}" FontSize="{StaticResource PhoneFontSizeNormal}" Foreground="{StaticResource PhoneForegroundBrush}" d:DesignHeight="52" d:DesignWidth="480"> <Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}"> <TextBlock Height="30" HorizontalAlignment="Left" Margin="12,10,0,0" Name="Index_itemtext" Text="" VerticalAlignment="Top" Width="145" /> <Image Height="34" HorizontalAlignment="Right" Margin="0,6,55,0" Source="blue_triangle.png" Name="IndexList_itemImage" Stretch="Uniform" VerticalAlignment="Top" Width="66" /> <Line Height="10" HorizontalAlignment="Left" Margin="0,38,0,0" Name="seperator_line" Stroke="White" StrokeThickness="2" VerticalAlignment="Top" Width="480" Stretch="Fill" Fill="#FFF5E9E9" /> </Grid> And the list box xaml: <ListBox Name="Index_list" ScrollViewer.VerticalScrollBarVisibility="Visible" VerticalContentAlignment="Top" SelectionChanged="on_selection" Margin="0,78,0,0"> </ListBox> Now when i add the items to the list ,the vertical scroll does not go till the last item i.e. it comes back to first row which stops from last item selection: for (int i = 0; i < gridSize; i++) { listbox_item list_item = new listbox_item(); list_item.Index_itemtext.FontSize = 25; list_item.Index_itemtext.Text = index[i]; list_item.IndexList_itemImage.Source = new BitmapImage(new Uri("some.png", UriKind.Relative)); list_item.seperator_line.StrokeThickness = 5; list_item.Margin = new Thickness(0, 0, 0, 5); Index_list.Items.Add(list_item); } Also the list row does not occupy the width of device in landscape mode,whereas the requirement is that the row item widens as the device width changes.Can someone help with these problems?

• How to iterate JPA collections in Google App engine

  - by palto

  Hi I use Google App Engine with datanucleus and JPA. I'm having a real hard time grasping how I'm supposed to read stuff from data store and pass it to JSP. If I load a list of POJOs with entitymanager and pass it to JSP, it crashes to org.datanucleus.exceptions.NucleusUserException: Object Manager has been closed. I understand why this is happening. Obviously because I fetch the list, close the entity manager and pass it to JSP, at which point it will fail because the list is lazy. How do I make the list NOT lazy without resorting to hacks like calling size() or something like that? Here is what I'm trying to do: @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { req.setAttribute("parties", getParties()); RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/parties.jsp"); dispatcher.forward(req, resp); } private List<Party> getParties(){ EntityManager em = entityManagerProvider.get(); try{ Query query = em.createQuery("SELECT p FROM Party p"); return query.getResultList(); }finally{ em.close(); } }

• How do i set the Transaction Isolation in EJB?

  - by Nitesh Panchal

  Hello, I am not able to find a way to set TransactionIsolation in ejb. Can anybody tell me how do i set it? I am using persistence. I have looked the following classes : EntityManager , EntityManagerFactory, UserTransaction. None of them seems to have any method like setTransactionIsolation or such. Do we need to change persistence.xml? I just read a book named Mastering EJB 3.0 4th edition. They gave a full 10 page theory about Isolation level that this problems occur and that occurs and such things but at the end they gave this paragraph :- "As we now know, the EJB standard does not deal with isolation levels directly, and rightly so. EJB is a component specification. It defines the behavior and contracts of a business component with clients and middleware infrastructure (containers) such that the component can be rendered as various middleware services properly. EJBs therefore are transactional components that interact with resource managers, such as the JDBC resource manager or JMS resource manager, via JTS, as part of a transaction. They are not, hence, resource components in themselves. Since isolation levels are very specific to the behavior and capabilities of the underlying resources, they should therefore be specified at the resource API levels. " What exactly does it mean? What is meant by resource level APIs? Please help me. If persistence has no way to set Isolation Level then why do they give such huge theory in an EJB book and make it heavy in weight unnecessarily :(
