  • Application hangs after changing language From “En-Us” to any global language in control panel

    - by user1764824
    I created a WinForms application using C#. When I try to change the culture info, my application gets hanged. Microsoft.Win32.SystemEvents.UserPreferenceChanged += new Microsoft.Win32.UserPreferenceChangedEventHandler(SystemEvents_UserPreferenceChanged); void SystemEvents_UserPreferenceChanged(object sender, Microsoft.Win32.UserPreferenceChangedEventArgs e) { if (!PreviousInstance()) { CultureInfo ObjCulture = new CultureInfo(CultureInfo.InvariantCulture.IetfLanguageTag, false); Thread.CurrentThread.CurrentCulture = ObjCulture; Application.CurrentCulture = ObjCulture; } } public void INIT() { CultureInfo objCultureInfo = null; try { objCultureInfo = new CultureInfo("en-US", false); objCultureInfo.NumberFormat.NumberDecimalSeparator = "."; objCultureInfo.NumberFormat.NegativeSign = "-"; objCultureInfo.NumberFormat.NumberNegativePattern = 1; //1 stands for -100. Application.CurrentCulture = objCultureInfo; } } After Changing Language ... My Application gets Hanged and i cant Debug anything When i Try to Evaluate things This Event Called only once.. But if try in a small application it comes every time when Language is changed... ... Nothing shown in Eventviewer either. How can I solve this problem? ..

  • Delphi - Message loop for Form created in DirectShow filter goes dead

    - by Robert Oschler
    I have a DirectShow filter created with Delphi Pro 6 and the DSPACK direct show library. I'm running under windows XP. I've tried creating the form dynamically when the container class for the DirectFilter has its constructor called, passing NIL into the constructor as the AOwner parameter (TMyForm.Create(nil) and then calling the Form's Show() method. The form does show but then appears to stop receiving windows messages because it never repaints and does not respond to input. As a test I then tried creating my own WndProc() and overriding the Form's WndProc(). My WndProc() did get called once but never again. I'm guessing it's because I'm a DLL and the context that I am running in is not "friendly" to the window message handler for the form; perhaps something to do with the thread that calls it or whatever. If someone could give me a tip on how to solve this or what the proper way to create a persistent window is from the context of a DirectShow filter I'd appreciate it. Note, as I said the window needs to be persistent so I can't create it as a Filter property page. Thanks, Robert

  • OpenNETCF.Stopwatch -> only ticks changing, not Elapsed

    - by pithyless
    I've been trying to track down a bug I thought was thread-related, but I think instead there is an issue with the way I am using OpenNETCF's Stopwatch. I am using OpenNETCF.IoC in my application, but for the sake of simplicity I moved the following code directly into a view: public partial class WorkoutView : SmartPart { ... private Stopwatch stopwatch; public WorkoutView() { ... stopwatch = new Stopwatch(); stopwatch.Reset(); stopwatch.Start(); WorkoutDisplayTimer = new Timer(); WorkoutDisplayTimer.Interval = 500; WorkoutDisplayTimer.Tick += new EventHandler(WorkoutDisplayTimer_Tick); WorkoutDisplayTimer.Enabled = true; } void WorkoutDisplayTimer_Tick(object sender, EventArgs e) { ... stopwatch.Stop(); lbl.Text = stopwatch.ElapsedTicks.ToString() + "NOT WORKING: " + stopwatch.Elapsed.ToString(); stopwatch.Start(); } ... } Long story short, looking at stopwatch in the debugger, the only values that ever get updated are ElapsedTicks, mElapsed, mStartPerfCount. Everything else is always zero. Is this expected behavior? Do I need to call an additional method to have the stopwatch calculate the Elapsed struct? (Note: stopwatch.ElapsedMilliseconds is also zero)

  • Problem setText UITextView

    - by Mat
    Hi i have a problem. I have 2 viewcontroller, in the first there is a mapView that implements the function "calloutAccessoryControlTapped" to tap a button on an annotation on the mapView; in the second there is just a UITextView. I want to change the text of the UITextView (and show the SecondViewController) in the second controller once the button on annotation is clicked; here is my code (FirstViewController) Header @interface FirstViewController<MKMapViewDelegate>{ IBOutlet MKMapView *mapView; SecondViewController *secondV;} @end Implementation @implementation FirstViewController - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control{ secondV = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; NSString *myS = @"some text here"; [secondV.myTextView setText:myS]; //Switch from this to the secondview [self presentModalViewController:secondV animated:YES]; @end (SecondViewController) Header @interface SecondViewController{ IBOutlet UITextView *myTextView; } @property(nonatomic, retain)UITextView *postitTextView; - (IBAction)backToMAp; - (void)setText:(NSString *)string; @end Implementation @implementation SecondViewController - (IBAction)backToMAp{ //Back To First View; [self dismissModalViewControllerAnimated:YES];} - (void)setText:(NSString *)string{ myTextView.text = string;} In this code when i tap on the button ([self presentModalViewController:secondV animated:YES];) on annotation the first time the second view show up but the text of UITextView don't change, when i back on the FirstView ([self dismissModalViewControllerAnimated:YES];) and then again tap the button to switch again to secondView the text of UITextView change..... Sorry for long thread and for my bad english!! Thank you stack!

  • Getting Vars to bind properly across multiple files

  • Unusual request URL in ASP.NET health monitoring event

    - by Troy Hunt
    I’m seeing a rather strange occurrence in the request information section of an ASP.NET health monitoring email I hope someone can shed some light on. This is a publicly facing website which runs on infrastructure at an Indian hosting provider. Health monitoring is notifying us of server errors via automated email but every now and then the requested URL appears as a totally different website. For example: Request information: Request URL: http://www.baidu.com/Default.aspx Request path: /Default.aspx User host address: 221.13.128.175 User: Is authenticated: False Authentication Type: Thread account name: NT AUTHORITY\NETWORK SERVICE Obviously the site in question is not Baidu and obviously this attribute is not the referrer either; the “Request URL” value is the path which has generated the error. The IP address is located in Beijing (coincidental given the Baidu address?) and in this instance it looks like the SQL server backend was not accessible (I haven't included the entire error message for security's sake). What would cause the request URL attribute to be arbitrarily changed to that of another site? I’ve never seen this occur in a health monitoring event before. Thanks!

  • Project Euler: Programmatic Optimization for Problem 7?

    - by bmucklow
    So I would call myself a fairly novice programmer as I focused mostly on hardware in my schooling and not a lot of Computer Science courses. So I solved Problem 7 of Project Euler: By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13. What is the 10001st prime number? I managed to solve this without problem in Java, but when I ran my solution it took 8 and change seconds to run. I was wondering how this could be optimized from a programming standpoint, not a mathematical standpoint. Is the array looping and while statements the main things eating up processing time? And how could this be optimized? Again not looking for a fancy mathematical equation..there are plenty of those in the solution thread. SPOILER My solution is listed below. public class PrimeNumberList { private ArrayList<BigInteger> primesList = new ArrayList<BigInteger>(); public void fillList(int numberOfPrimes) { primesList.add(new BigInteger("2")); primesList.add(new BigInteger("3")); while (primesList.size() < numberOfPrimes){ getNextPrime(); } } private void getNextPrime() { BigInteger lastPrime = primesList.get(primesList.size()-1); BigInteger currentTestNumber = lastPrime; BigInteger modulusResult; boolean prime = false; while(!prime){ prime = true; currentTestNumber = currentTestNumber.add(new BigInteger("2")); for (BigInteger bi : primesList){ modulusResult = currentTestNumber.mod(bi); if (modulusResult.equals(BigInteger.ZERO)){ prime = false; break; } } if(prime){ primesList.add(currentTestNumber); } } } public BigInteger get(int primeTerm) { return primesList.get(primeTerm - 1); } }

  • BackgroundWorker Not working in VSTO

    - by Chris
    I have a background worker. Before I invoke the worker I disable a button and make a gif visible. I then invoke the runworkerasync method and it runs fine until comleteion. On the 'RunWorkerCompleted()' I get a cross thread error.

  • Web service request ignores basic WSDL XML element restrictions

    - by Oliver
    Hi all, I have encountered some difficulties while trying to validate an incoming soap message to a service I have running on JBoss AS (v. 5.1.0). In my code, I have explicitly set some fields to be required, eg: public class MyClass { @XmlElement(required=true, nillable=false) private List<myOtherObjects> myList; } This requirement is also reflected in the WSDL (note the lack of minOccurs="0"): <xs:element maxOccurs="unbounded" name="myList" type="tns:myOtherObjects" /> However, when I do a test soap message that has myList set to empty or null, these restrictions are completely ignored, forcing me to validate manually within the application logic on the service. I did some searching on the Internet and found out that, on WebLogic, the validation does not seem to be enabled by default, though it can be turned on by modifying the weblogic-webservices.xml file. (http://forums.oracle.com/forums/thread.jspa?threadID=783972&tstart=115) I’m wondering if there is something similar that I have to do with JBoss AS to enable automatic validation before the soap message reaches the service. Any help would be greatly appreciated. Oliver

  • WinForms Load Event / Static Initialization Strangeness

    - by Eric J.
    Background I'm troubleshooting an WinForms 2.0 program that's already been burned to CD for distribution to an internet-challenged target audience. Some users are experiencing a fatal error that I can reproduce locally. Reproducing the Error I get the fatal error when I log into my Vista box using a standard user that I just created, even if I run the program as administrator. I do not get the fatal error when I log in as local administrator. I'm not sure that being administrator is necessarily the trigger (since runas did not help). I have reproduced this half a dozen times under each account with consistent results. The faulty code Base.cs (base class for several user controls, only one of which is shown on first screen) private void BaseWindow_Load(object sender, EventArgs e) { // This message shown once in both cases MessageBox.Show("BaseWindow_Load for " + this.GetType().FullName); SkinManager.ApplySkin(this); } SkinManager.cs private static Skin skin = null; public static void ApplySkin(UserControl applyTo) { if (skin == null) { skin = new Skin(SkinsDirectory, "Default"); } } Skin.cs internal Skin(string skinPath, string skinName) { config = SkinConfig.Load(path); } SkinConfig.cs public static SkinConfig Load(string path) { // This message shown only once running as Admin but twice running as standard user System.Windows.Forms.MessageBox.Show("@1"); // !!! LOCK path HERE !!! } A user control loads on the first form, which triggers a call to SkinManager.ApplySkin, which checks if skin is null and, if so assigns it (without thread synchronization or recursion protection), which ultimately causes a file to be opened. When logged in as local admin, that sequence completes just fine. When logged in as my test standard user, ApplySkin is always called a second time while skin is still null, causing a second attempt to load, causing the file to be locked on the second attempt. The error handling is draconian at this point and the program terminates. The Question While this code can be easily fixed, I would like to understand why the error is happening only in some cases.

  • IHttpAsyncHandler and IObservable web requests

    - by McLovin
    Within Async handler I'm creating an IObservable from webrequest which returns a redirect string. I'm subscribing to that observable and calling AsyncResult.CompleteCall() but I'm forced to use Thread.Sleep(100) in order to get it executed. And it doesn't work every time. I'm pretty sure this is not correct. Could you please shine some light. Thank you! public IAsyncResult BeginProcessRequest(HttpContext context, AsyncCallback cb, object state) { _context = context; _ar = new AsyncResult(cb, state); _tweet = context.Request["tweet"]; string url = context.Request["url"]; if(String.IsNullOrEmpty(_tweet) || String.IsNullOrEmpty(url)) { DisplayError("<h2>Tweet or url cannot be empty</h2>"); return _ar; } _oAuth = new oAuthTwitterRx(); using (_oAuth.AuthorizationLinkGet().Subscribe(p => { _context.Response.Redirect(p); _ar.CompleteCall(); }, exception => DisplayError("<h2>Unable to connect to twitter, please try again</h2>") )) return _ar; } public class AsyncResult : IAsyncResult { private AsyncCallback _cb; private object _state; private ManualResetEvent _event; private bool _completed = false; private object _lock = new object(); public AsyncResult(AsyncCallback cb, object state) { _cb = cb; _state = state; } public Object AsyncState { get { return _state; } } public bool CompletedSynchronously { get { return false; } } public bool IsCompleted { get { return _completed; } } public WaitHandle AsyncWaitHandle { get { lock (_lock) { if (_event == null) _event = new ManualResetEvent(IsCompleted); return _event; } } } public void CompleteCall() { lock (_lock) { _completed = true; if (_event != null) _event.Set(); } if (_cb != null) _cb(this); } }

  • Binding to WPF ViewModel properties

  • How should I implement reverse AJAX in a Django application?

    - by Carson Myers
    How should I implement reverse AJAX when building a chat application in Django? I've looked at Django-Orbited, and from my understanding, this puts a comet server in front of the HTTP server. This seems fine if I'm just running the Django development server, but how does this work when I start running the application from mod_wsgi? How does having the orbited server handling every request scale? Is this the correct approach? I've looked at another approach (long polling) that seems like it would work, although I'm not sure what all would be involved. Would the client request a page that would live in its own thread, so as not to block the rest of the application? Would it even block? Wouldn't the script requested by the client have to continuously poll for information? Which of the approaches is more proper? Which is more portable, scalable, sane, etc? Are there other good approaches to this (aside from the client polling for messages) that I have overlooked?

  • PowerShell: How to find and uninstall a MS Office Update

    - by Hank
    I've been hunting for a clean way to uninstall an MSOffice security update on a large number of workstations. I've found some awkward solutions, but nothing as clean or general like using PowerShell and get-wmiobject with Win32_QuickFixEngineering and the .Uninstall method on the resulting object. [Apparently, Win32_QuickFixEngineering only refers to Windows patches. See: http://social.technet.microsoft.com/Forums/en/winserverpowershell/thread/93cc0731-5a99-4698-b1d4-8476b3140aa3 ] Question 1: Is there no way to use get-wmiobject to find MSOffice updates? There are so many classes and namespaces, I have to wonder. This particualar Office update (KB978382) can be found in the registry here (for Office Ultimate): HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\{91120000-002E-0000-0000-0000000FF1CE}_ULTIMATER_{6DE3DABF-0203-426B-B330-7287D1003E86} which kindly shows the uninstall command of: msiexec /package {91120000-002E-0000-0000-0000000FF1CE} /uninstall {6DE3DABF-0203-426B-B330-7287D1003E86} and the last GUID seems constant between different versions of Office. I've also found the update like this: $wu = new-object -com "Microsoft.Update.Searcher" $wu.QueryHistory(0,$wu.GetTotalHistoryCount()) | where {$_.Title -match "KB978382"} I like this search because it doesn't require any poking around in the registry, but: Question 2: If I've found it like this, what can I do with the found information to facilitate the Uninstall? Thanks

  • SmtpClient.SendAsync - How to ensure my application doesn't finish before callback?

    - by James
    Hi, I need to send emails asychronously through a console application. I need to do some DB updates on the callback but my application is exiting before the callback code gets run! How can I stop this from happening in a nice manner rather than simply guessing how long to wait before exiting. I would imagine the Async calls get placed in some form of thread? Is it possible to check if any are waiting to be called? Sample Code private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. String token = (string) e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { // update DB Console.WriteLine("Message sent."); } } public static void Main(string[] args) { var users = Repository.GetUsers(); SmtpClient client = new SmtpClient("Host"); client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback); MailAddress from = new MailAddress("[email protected]", "System", Encoding.UTF8); foreach (var user in users) { MailAddress to = new MailAddress(user.Email); MailMessage message = new MailMessage(from, to); message.Body = "This is a test"; message.BodyEncoding = System.Text.Encoding.UTF8; message.Subject = "test message 1" + someArrows; message.SubjectEncoding = System.Text.Encoding.UTF8; string userState = String.Format("Message for user id {0}", user.ID); client.SendAsync(message, userState); message.Dispose(); } // need to wait here until I have received a callback for each message // otherwise the application will exit }

  • Time to start returning IQueryable<T> instead of IList<T> to my Web UI / Web API Layer?

    - by JohnnyO
    I've got a multi-layer application that starts with the repository pattern for all data access and it returns IQueryable to the Services layer. The Services layer, which includes all of the business logic, returns IList to the Controllers (note: I'm using ASP.NET MVC for the UI layer). The benefit of returning IQueryable in the data access layer is that it allows my repositories to be extremely simple and the database queries to be deferred. However, I'm triggering the database queries in my services layer so that my unit tests is more reliable and I don't give flexibility to the Controllers to reshape my queries. However, I've recently encountered several situations where deferring the execution of queries down to the Controllers would have been significantly more performant because the Controllers had to do some projections on the data that was UI specific. Additionally, with the emergence of things like oData, I was starting to wonder if end points (e.g. web UI or web apis) should be working directly with IQueryable. What are your thoughts? Is it time to start returning IQueryable from the services layer to the UI layer? Or stick with IList? This thread here: http://stackoverflow.com/questions/718624/to-return-iqueryablet-or-not-return-iqueryablet seems to vouch for returning IList to the UI layers, but I was wondering if things are changing because of new emerging technologies and techniques.

We have a company training website which staff can access via the kiosk, and the main content is interactive flash training videos. Our target machines are by no means 'beefy', they are Atom n270s @ 1.6Ghz with 1Gb RAM. As it stands the videos are all but unusable when used from within the Air application, the application becomes completely unresponsive (100% cpu usage, click events take approx 5-10 seconds to register). So far I have tried: increasing the default frame rate from 24fps to 60. No improvement. nativeWindow.stage.frameRate = 60; running the videos in a stripped down version of my app, just a full screen HTMLLoader component pointed at the training website. No better than before. disabled hyper threading. The Atom CPU is split into two virtual cores, and the AIR app was only able to use one thread so maxed out at 50% CPU usage. Since the kiosk will only run the AIR app I am happy to loose hyper threading to increase the performance of the Air app. Marginal Improvement. The same website with the same videos is responsive if viewed in ie7 on the same machine, although Internet Explorer takes advantage of the CPU’s hyper threading. The flash videos are built with Adobe Captivate and from what I understand employee JavaScript to relay results back to the server. I will add more information about the video content asap as the training guru is back in the office later this week.

  • Java FileLock for Reading and Writing

    - by bobtheowl2
    I have a process that will be called rather frequently from cron to read a file that has certain move related commands in it. My process needs to read and write to this data file - and keep it locked to prevent other processes from touching it during this time. A completely separate process can be executed by a user to (potential) write/append to this same data file. I want these two processes to play nice and only access the file one at a time. The nio FileLock seemed to be what I needed (short of writing my own semaphore type files), but I'm having trouble locking it for reading. I can lock and write just fine, but when attempting to create lock when reading I get a NonWritableChannelException. Is it even possible to lock a file for reading? Seems like a RandomAccessFile is closer to what I need, but I don't see how to implement that. Here is the code that fails: FileInputStream fin = new FileInputStream(f); FileLock fl = fin.getChannel().tryLock(); if(fl != null) { System.out.println("Locked File"); BufferedReader in = new BufferedReader(new InputStreamReader(fin)); System.out.println(in.readLine()); ... The exception is thrown on the FileLock line. java.nio.channels.NonWritableChannelException at sun.nio.ch.FileChannelImpl.tryLock(Unknown Source) at java.nio.channels.FileChannel.tryLock(Unknown Source) at Mover.run(Mover.java:74) at java.lang.Thread.run(Unknown Source) Looking at the JavaDocs, it says Unchecked exception thrown when an attempt is made to write to a channel that was not originally opened for writing. But I don't necessarily need to write to it. When I try creating a FileOutpuStream, etc. for writing purposes it is happy until I try to open a FileInputStream on the same file.

  • OpenCV to JNI how to make it work?

    - by user293252
    I am tring to use opencv and java for face detection, and in that pursit i found this "JNI2OPENCV" file....but i am confused on how to make it work, can anyone help me? http://img519.imageshack.us/img519/4803/askaj.jpg and the following is the FaceDetection.java class JNIOpenCV { static { System.loadLibrary("JNI2OpenCV"); } public native int[] detectFace(int minFaceWidth, int minFaceHeight, String cascade, String filename); } public class FaceDetection { private JNIOpenCV myJNIOpenCV; private FaceDetection myFaceDetection; public FaceDetection() { myJNIOpenCV = new JNIOpenCV(); String filename = "lena.jpg"; String cascade = "haarcascade_frontalface_alt.xml"; int[] detectedFaces = myJNIOpenCV.detectFace(40, 40, cascade, filename); int numFaces = detectedFaces.length / 4; System.out.println("numFaces = " + numFaces); for (int i = 0; i < numFaces; i++) { System.out.println("Face " + i + ": " + detectedFaces[4 * i + 0] + " " + detectedFaces[4 * i + 1] + " " + detectedFaces[4 * i + 2] + " " + detectedFaces[4 * i + 3]); } } public static void main(String args[]) { FaceDetection myFaceDetection = new FaceDetection(); } } CAn anyone tell me how can i make this work on Netbeans?? I tried Google but help on this particular topic is very meger. I have added the whole folder as Llibrary in netbeans project and whe i try to run the file i get the followig wrroes. Exception in thread "main" java.lang.UnsatisfiedLinkError: FaceDetection.JNIOpenCV.detectFace(IILjava/lang/String;Ljava/lang/String;)[I at FaceDetection.JNIOpenCV.detectFace(Native Method) at FaceDetection.FaceDetection.<init>(FaceDetection.java:19) at FaceDetection.FaceDetection.main(FaceDetection.java:29) Java Result: 1 BUILD SUCCESSFUL (total time: 2 seconds) CAn anyone tell me the exact way to work with this? like what all i have to do?

  • Using StringBuilder to process csv files to save heap space

    - by portoalet
    I am reading a csv file that has about has about 50,000 lines and 1.1MiB in size (and can grow larger). In Code1, I use String to process the csv, while in Code2 I use StringBuilder (only one thread executes the code, so no concurrency issues) Using StringBuilder makes the code a little bit harder to read that using normal String class. Am I prematurely optimizing things with StringBuilder in Code2 to save a bit of heap space and memory? Code1 fr = new FileReader(file); BufferedReader reader = new BufferedReader(fr); String line = reader.readLine(); while ( line != null ) { int separator = line.indexOf(','); String symbol = line.substring(0, seperator); int begin = separator; separator = line.indexOf(',', begin+1); String price = line.substring(begin+1, seperator); // Publish this update publisher.publishQuote(symbol, price); // Read the next line of fake update data line = reader.readLine(); } Code2 fr = new FileReader(file); StringBuilder stringBuilder = new StringBuilder(reader.readLine()); while( stringBuilder.toString() != null ) { int separator = stringBuilder.toString().indexOf(','); String symbol = stringBuilder.toString().substring(0, separator); int begin = separator; separator = stringBuilder.toString().indexOf(',', begin+1); String price = stringBuilder.toString().substring(begin+1, separator); publisher.publishQuote(symbol, price); stringBuilder.replace(0, stringBuilder.length(), reader.readLine()); }

  • .NET Process.Kill() in a safe way

    - by Orborde
    I'm controlling a creaky old FORTRAN simulator from a VB.NET GUI, using redirected I/O to communicate with the simulator executable. The GUI pops up a "status" window with a progress bar, estimated time, and a "STOP" button (Button_Stop). Now, I want the Button_Stop to terminate the simulator process immediately. The obvious way to do this is to call Kill() on the Child Process object. This gives an exception if it's done after the process has exited, but I can test whether the process is exited before trying to kill it, right? OK, so I do the following when the button is clicked: If Not Child.HasExited Then Child.Kill() Button_Stop.Enabled = False End If However, what if the process happens to exit between the test and the call to Kill()? In that case, I get an exception. The next thing to occur to me was that I can do Button_Stop.Enabled = False in the Process.Exited event handler, and thus prevent the Child.Kill() call in the Button_Stop.Clicked handler. But since the Process.Exited handler is called on a different thread, that still leaves the following possible interleaving: Child process exits. Process.Exited fires, calls Invoke to schedule the Button_Stop.Enabled = False User clicks on Button_Stop, triggering Child.Kill() Button_Stop.Enabled = False actually happens. An exception would then be thrown on step 3. How do I kill the process without any race conditions? Am I thinking about this entirely wrong?
