  • Spring.Net Message Selectors with compound statements don't seem to be working

    - by Jonathan Beerhalter
    I'm using Spring.NET to connect to ActiveMQ and do some fairly simple pub sub routing. Everything works fine when my selector is a simple expression like Car='Honda' but if I try a compound expression like Car='Honda' AND Make='Pilot' I never get any matches on my subscription. Here's the code to generate the subscription, does anyone see where I might be doing something wrong? public bool AddSubscription(string topicName, Dictionary<string,string> selectorList, GDException exp) { try { ActiveMQTopic topic = new ActiveMQTopic(topicName); string selectorString = ""; if (selectorList.Keys.Count == 0) { // Select all items for this topic selectorString = "2>1"; } else { foreach (string key in selectorList.Keys) { selectorString += key + " = '" + selectorList[key] + "'" + " AND "; } selectorString = selectorString.Remove(selectorString.Length - 5, 5); } IMessageConsumer consumer = this._subSession.CreateConsumer(topic, selectorString, false); if (consumer != null) { _consumers.Add(consumer); consumer.Listener += new MessageListener(HandleRecieveMessage); return true; } else { exp.SetValues("Error adding subscription, null consumer returned"); return false; } } catch (Exception ex) { exp.SetValues(ex); return false; } } And then the code to send the message, which seems simple enough to me public void SendMessage(GDPubSubMessage messageToSend) { if (!this.isDisposed) { if (_producers.ContainsKey(messageToSend.Topic)) { IBytesMessage bytesMessage = this._pubSession.CreateBytesMessage(messageToSend.Payload); foreach (string key in messageToSend.MessageProperties.Keys) { bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); } _producers[messageToSend.Topic].Send(bytesMessage, false, (byte)255, TimeSpan.FromSeconds(1)); } else { ActiveMQTopic topic = new ActiveMQTopic(messageToSend.Topic); _producers.Add(messageToSend.Topic, this._pubSession.CreateProducer(topic)); IBytesMessage bytesMessage = this._pubSession.CreateBytesMessage(messageToSend.Payload); foreach (string key in messageToSend.MessageProperties.Keys) { bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); } _producers[messageToSend.Topic].Send(bytesMessage); } } else { throw new ObjectDisposedException(this.GetType().FullName); } } 07/102009: Update Ok, found the problem bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); This justs sets a single property, so my messages are only being tagged with a single property, hence the combo subscription never gets hit. Anyone know how to add more properties? You'd think bytesMessage.Properties would have a Add method, but it doesn't.

  • Problem Executing Async Web Request

    - by davidhayes
    Hi Can anyone tell me what I've done wrong with this simple code? When I run it it hangs on using (Stream postStream = request.EndGetRequestStream(asynchronousResult)) If I comment out the requestState.Wait.WaitOne(); line the code executes correctly but obviously doesn't wait for the response. I'm guessing the the call to EndGetRequestStream is somehow returning me to the context of the main thread?? I'm pretty sure my code is essentially the same as the sample though (MSDN Documentation) using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using System.IO; using System.Text; namespace SBRemoteClient { public class JSONClient { public string ExecuteJSONQuery(string url, string query) { System.Uri uri = new Uri(url); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); request.Method = "POST"; request.Accept = "application/json"; byte[] requestBytes = Encoding.UTF8.GetBytes(query); RequestState requestState = new RequestState(request, requestBytes); IAsyncResult resultRequest = request.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), requestState); requestState.Wait.WaitOne(); IAsyncResult resultResponse = (IAsyncResult)request.BeginGetResponse(new AsyncCallback(GetResponseStreamCallback), requestState); requestState.Wait.WaitOne(); return requestState.Response; } private static void GetRequestStreamCallback(IAsyncResult asynchronousResult) { try { RequestState requestState = (RequestState)asynchronousResult.AsyncState; HttpWebRequest request = requestState.Request; using (Stream postStream = request.EndGetRequestStream(asynchronousResult)) { postStream.Write(requestState.RequestBytes, 0, requestState.RequestBytes.Length); } requestState.Wait.Set(); } catch (Exception e) { Console.Out.WriteLine(e); } } private static void GetResponseStreamCallback(IAsyncResult asynchronousResult) { RequestState requestState = (RequestState)asynchronousResult.AsyncState; HttpWebRequest request = requestState.Request; using (HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult)) { using (Stream responseStream = response.GetResponseStream()) { using (StreamReader streamRead = new StreamReader(responseStream)) { requestState.Response = streamRead.ReadToEnd(); requestState.Wait.Set(); } } } } } }

  • NSSortDescriptor for NSFetchRequestController causes crash when value of sorted attribute is changed

    - by AJ
    I have an Core Data Entity with a number of attributes, which include amount(float), categoryTotal(float) and category(string) The initial ViewController uses a FethchedResultsController to retrieve the entities, and sorts them based on the category and then the categoryTotal. No problems so far. NSManagedObjectContext *moc = [self managedObjectContext]; NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"Transaction" inManagedObjectContext:moc]; NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; [request setEntity:entityDescription]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(dateStamp >= %@) AND (dateStamp =< %@)", startDate, endDate]; [request setPredicate:predicate]; NSSortDescriptor *sortByCategory = [[NSSortDescriptor alloc] initWithKey:@"category" ascending:sortOrder]; NSSortDescriptor *sortByTotals = [[NSSortDescriptor alloc] initWithKey:@"categoryTotal" ascending:sortOrder]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortByTotals, sortByCategory, nil]; [request setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:managedObjectContext sectionNameKeyPath:@"category" cacheName:nil]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; On selecting a row (tableView:didSelectRowAtIndexPath), another view controller is loaded that allows editing of the amount field for the selected entity. Before returning to the first view, categoryTotal is updated by the new ‘amount’. The problem comes when returning to the first view controller, the app bombs with *Serious application error. Exception was caught during Core Data change processing: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted). with userInfo (null) Program received signal: “EXC_BAD_ACCESS”.* This seems to be courtesy of NSSortDescriptor *sortByTotals = [[NSSortDescriptor alloc] initWithKey:@"categoryTotal" ascending:sortOrder]; If I remove this everything works as expected, but obviously without the sorting I want. I'm guessing this is to do with the sorting order changing due to categoryTotal changing (deletion / insertion) but can't find away fix this. I've verified that values are being modified correctly in the second view, so it appears down to the fetchedResultsController being confused. If the categoryAmount is changed to one that does not change the sort order, then no error is generated I'm not physically changing (ie deleting) the number of items the fetchedResultsController is returning ... the only other issue I can find that seem to generate this error Any ideas would be most welcome Thanks, AJ

  • How do compare dates when one of those are in string format in android

    - by Raj
    I am very much new to android so need some good help with a code example. I am getting a date in form of string from a server in the following format 2012-08-17 00:00:00 I want to compare this string with current date to find the difference between the dates in the form of year, months and days... I tried playing around it in the following code Date currentDate = new Date(System.currentTimeMillis()); Log.v("@@@@@@@@@","Current Date: " + currentDate); Date passDate = new SimpleDateFormat().parse(passDateString); Log.v("@@@@@@@@@","Pass Date: " + passDate); dateDifference = passDate.compareTo(currentDate); but it returned with following exception 04-15 12:08:29.101: V/@@@@@@@@@(1161): Current Date: Sun Apr 15 12:08:29 GMT+01:00 2012 04-15 12:08:29.101: W/System.err(1161): java.text.ParseException: Unparseable date: 2012-08-17 00:00:00 04-15 12:08:29.111: W/System.err(1161): at java.text.DateFormat.parse(DateFormat.java:645) 04-15 12:08:29.111: W/System.err(1161): at org.apis.PassesListItemAdapter.getView(PassesListItemAdapter.java:77) 04-15 12:08:29.111: W/System.err(1161): at android.widget.AbsListView.obtainView(AbsListView.java:1315) 04-15 12:08:29.111: W/System.err(1161): at android.widget.ListView.makeAndAddView(ListView.java:1727) 04-15 12:08:29.111: W/System.err(1161): at android.widget.ListView.fillDown(ListView.java:652) 04-15 12:08:29.111: W/System.err(1161): at android.widget.ListView.fillFromTop(ListView.java:709) 04-15 12:08:29.111: W/System.err(1161): at android.widget.ListView.layoutChildren(ListView.java:1580) 04-15 12:08:29.111: W/System.err(1161): at android.widget.AbsListView.onLayout(AbsListView.java:1147) 04-15 12:08:29.111: W/System.err(1161): at android.view.View.layout(View.java:7034) 04-15 12:08:29.111: W/System.err(1161): at android.widget.RelativeLayout.onLayout(RelativeLayout.java:909) 04-15 12:08:29.111: W/System.err(1161): at android.view.View.layout(View.java:7034) 04-15 12:08:29.111: W/System.err(1161): at android.widget.FrameLayout.onLayout(FrameLayout.java:333) 04-15 12:08:29.111: W/System.err(1161): at android.view.View.layout(View.java:7034) 04-15 12:08:29.111: W/System.err(1161): at android.widget.FrameLayout.onLayout(FrameLayout.java:333) 04-15 12:08:29.111: W/System.err(1161): at android.view.View.layout(View.java:7034) 04-15 12:08:29.111: W/System.err(1161): at android.view.ViewRoot.performTraversals(ViewRoot.java:1049) 04-15 12:08:29.111: W/System.err(1161): at android.view.ViewRoot.handleMessage(ViewRoot.java:1744) 04-15 12:08:29.111: W/System.err(1161): at android.os.Handler.dispatchMessage(Handler.java:99) 04-15 12:08:29.111: W/System.err(1161): at android.os.Looper.loop(Looper.java:144) 04-15 12:08:29.111: W/System.err(1161): at android.app.ActivityThread.main(ActivityThread.java:4937) 04-15 12:08:29.111: W/System.err(1161): at java.lang.reflect.Method.invokeNative(Native Method) 04-15 12:08:29.111: W/System.err(1161): at java.lang.reflect.Method.invoke(Method.java:521) 04-15 12:08:29.111: W/System.err(1161): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 04-15 12:08:29.111: W/System.err(1161): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 04-15 12:08:29.111: W/System.err(1161): at dalvik.system.NativeStart.main(Native Method) I am stuck... please help Raj

  • using LoadControl with object initializer to create properties

    - by lloydphillips
    In the past I've used UserControls to create email templates which I can fill properties on and then use LoadControl and then RenderControl to get the html for which to use for the body text of my email. This was within asp.net webforms. I'm in the throws of building an mvc website and wanted to do something similar. I've actually considered putting this functionality in a seperate class library and am looking into how I can do this so that in my web layer I can just call EmailTemplate.SubscriptionEmail() which will then generate the html from my template with properties in relevant places (obviously there needs to be parameters for email address etc in there). I wanted to create a single Render control method for which I can pass a string to the path of the UserControl which is my template. I've come across this on the web that kind of suits my needs: public static string RenderUserControl(string path, string propertyName, object propertyValue) { Page pageHolder = new Page(); UserControl viewControl = (UserControl)pageHolder.LoadControl(path); if (propertyValue != null) { Type viewControlType = viewControl.GetType(); PropertyInfo property = viewControlType.GetProperty(propertyName); if (property != null) property.SetValue(viewControl, propertyValue, null); else { throw new Exception(string.Format( "UserControl: {0} does not have a public {1} property.", path, propertyName)); } } pageHolder.Controls.Add(viewControl); StringWriter output = new StringWriter(); HttpContext.Current.Server.Execute(pageHolder, output, false); return output.ToString(); } My issue is that my UserControl(s) may have multiple and differing properties. So SubscribeEmail may require FirstName and EmailAddress where another email template UserControl (lets call it DummyEmail) would require FirstName, EmailAddress and DateOfBirth. The method above only appears to carry one parameter for propertyName and propertyValue. I considered an array of strings that I could put the varying properties into but then I thought it'd be cool to have an object intialiser so I could call the method like this: RenderUserControl("EmailTemplates/SubscribeEmail.ascs", new object() { Firstname="Lloyd", Email="[email protected]" }) Does that make sense? I was just wondering if this is at all possible in the first place and how I'd implement it? I'm not sure if it would be possible to map the properties set on 'object' to properties on the loaded user control and if it is possible where to start in doing this? Has anyone done something like this before? Can anyone help? Lloyd

  • Modify values on-the-fly during SqlAdapter.Fill( )

    - by Timothy
    What would the proper way be to modify values on the fly as they are loaded into a DataTable by SqlAdapter.Fill()? I have globalized my application's log messages. An integer indicating the event type and serialized data relevant to the event is stored in the database as show below. When I display the logged events through a DataGridView control to the user, I interpolate the data to a formatting string. event_type event_timestamp event_details ============================================ 3 2010-05-04 20:49:58 jsmith 1 2010-05-04 20:50:42 jsmith ... I am currently iterating through the DataTable's rows to format the messages. public class LogDataTable : DataTable { public LogDataTable() { Locale = CultureInfo.CurrentCulture; Columns.AddRange(new DataColumn[] { new DataColumn("event_type", typeof(Int32)), new DataColumn("event_timestamp", typeof(DateTime)), new DataColumn("event_details", typeof(String))}); } } ... using (SqlDataAdapter adapter = new SqlDataAdapter(...)) { adapter.SelectCommand.Parameters.AddRange(new Object[] { ... }); adapter.Fill(table); } foreach (DataRow row in table.Rows) { switch ((LogEventType)row["event_type"]) { case LogEventType.Create: row["event_details"] = String.Format(Resources.Strings.LogEventCreateMsg, row["event_details"]; break; case LogEventType.Create: row["event_details"] = String.Format(Resources.Strings.LogEventCreateMsg, row["event_details"]; break; ... The end result as displayed would resemble: Type Date and Time Details ==================================================================== [icon] 2010-05-04 20:49:58 Failed login attempt with username jsmith [icon] 2010-05-04 20:50:42 Successful login with username jsmith ... It seems wasteful to iterate the result set twice-- once as the table is filled by the adapter, and again to perform the replacements. I would really like to do the replacement on-the-fly in my LogDataTable class as it is being populated. I have tried overriding an OnRowChanging method in LogDataTable, which throws an InRowChangingEventException. protected override void OnRowChanging(DataRowChangeEventArgs e) { base.OnRowChanging(e); switch ((LogEventType)row["event_type"]) ... I have tried overriding an OnRowChanged method, which throws a StackOverflowException (I assume changing it re-triggers the method ad infinitum?). I have tried overriding an OnTableNewRow method, which does not throw an exception but appears not to be invoked (I assume only when a user adds a row in the view, which I've prevented). I'd greatly appreciate any assistance anyone can give me.

  • How to do a proper search with nhibernate

    - by Denis Rosca
    Hello everyone, i'm working on a small project that is supposed to allow basic searches of the database. Currently i'm using nhibernate for the database interaction. In the database i have 2 tables: Person and Address. The Person table has a many-to-one relationship with Address. The code i've come up with for doing searches is: public IList<T> GetByParameterList(List<QueryParameter> parameterList) { if (parameterList == null) { return GetAll(); } using (ISession session = NHibernateHelper.OpenSession()) { ICriteria criteria = session.CreateCriteria<T>(); foreach (QueryParameter param in parameterList) { switch (param.Constraint) { case ConstraintType.Less: criteria.Add(Expression.Lt(param.ParameterName, param.ParameterValue)); break; case ConstraintType.More: criteria.Add(Expression.Gt(param.ParameterName, param.ParameterValue)); break; case ConstraintType.LessOrEqual: criteria.Add(Expression.Le(param.ParameterName, param.ParameterValue)); break; case ConstraintType.EqualOrMore: criteria.Add(Expression.Ge(param.ParameterName, param.ParameterValue)); break; case ConstraintType.Equals: criteria.Add(Expression.Eq(param.ParameterName, param.ParameterValue)); break; case ConstraintType.Like: criteria.Add(Expression.Like(param.ParameterName, param.ParameterValue)); break; } } try { IList<T> result = criteria.List<T>(); return result; } catch { //TODO: Implement some exception handling throw; } } } The query parameter is a helper object that i use to create criterias and send it to the dal, it looks like this: public class QueryParameter { public QueryParameter(string ParameterName, Object ParameterValue, ConstraintType constraintType) { this.ParameterName = ParameterName; this.ParameterValue = ParameterValue; this.Constraint = constraintType; } public string ParameterName { get; set; } public Object ParameterValue { get; set; } public ConstraintType Constraint { get; set; } } Now this works well if i'm doing a search like FirstName = "John" , but not when i try to give a parameter like Street = "Some Street". It seems that nhibernate is looking for a street column in the Person table but not in the Address table. Any idea on how should i change my code for so i could do a proper search? Tips? Maybe some alternatives? Disclaimer: i'm kind of a noob so please be gentle ;) Thanks, Denis.

  • Which style is preferable when writing this boolean expression?

    - by Jeppe Stig Nielsen
    I know this question is to some degree a matter of taste. I admit this is not something I don't understand, it's just something I want to hear others' opinion about. I need to write a method that takes two arguments, a boolean and a string. The boolean is in a sense (which will be obvious shortly) redundant, but it is part of a specification that the method must take in both arguments, and must raise an exception with a specific message text if the boolean has the "wrong" value. The bool must be true if and only if the string is not null or empty. So here are some different styles to write (hopefully!) the same thing. Which one do you find is the most readable, and compliant with good coding practice? // option A: Use two if, repeat throw statement and duplication of message string public void SomeMethod(bool useName, string name) { if (useName && string.IsNullOrEmpty(name)) throw new SomeException("..."); if (!useName && !string.IsNullOrEmpty(name)) throw new SomeException("..."); // rest of method } // option B: Long expression but using only && and || public void SomeMethod(bool useName, string name) { if (useName && string.IsNullOrEmpty(name) || !useName && !string.IsNullOrEmpty(name)) throw new SomeException("..."); // rest of method } // option C: With == operator between booleans public void SomeMethod(bool useName, string name) { if (useName == string.IsNullOrEmpty(name)) throw new SomeException("..."); // rest of method } // option D1: With XOR operator public void SomeMethod(bool useName, string name) { if (!(useName ^ string.IsNullOrEmpty(name))) throw new SomeException("..."); // rest of method } // option D2: With XOR operator public void SomeMethod(bool useName, string name) { if (useName ^ !string.IsNullOrEmpty(name)) throw new SomeException("..."); // rest of method } Of course you're welcome to suggest other possibilities too. Message text "..." would be something like "If 'useName' is true a name must be given, and if 'useName' is false no name is allowed".

  • android app crashes if keyboard was shown

    - by Jaume
    I have an activity that I force keyboard to appears using, InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); keyboard appears properly and also obscured when needed. Problem is when I finish the activity, app crashes. If the activity never shows keyboard or shows it without start editing text, it is finished with no errors but if you just write one single character or more, app will crash. How to solve it? thank you. method used to finish activity, boto_back.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0); finish(); } }); @Override public void onDestroy() { if (adMob != null) { // Destroy the AdView. adMob.destroy(); } super.onDestroy(); } logcat, 07-07 19:04:25.191: E/AndroidRuntime(8443): FATAL EXCEPTION: main 07-07 19:04:25.191: E/AndroidRuntime(8443): java.lang.RuntimeException: Unable to destroy activity {com.xxxx.xxxx/com.xxxx.projecte1.TabBar_iOSActivity}: java.lang.RuntimeException: Unable to destroy activity {com.xxxx.xxxx/com.xxxx.projecte1.webPush}: java.lang.NullPointerException 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.performDestroyActivity(ActivityThread.java:2693) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.handleDestroyActivity(ActivityThread.java:2711) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.access$2100(ActivityThread.java:121) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:976) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.os.Handler.dispatchMessage(Handler.java:99) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.os.Looper.loop(Looper.java:130) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-07 19:04:25.191: E/AndroidRuntime(8443): at java.lang.reflect.Method.invokeNative(Native Method) 07-07 19:04:25.191: E/AndroidRuntime(8443): at java.lang.reflect.Method.invoke(Method.java:507) 07-07 19:04:25.191: E/AndroidRuntime(8443): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-07 19:04:25.191: E/AndroidRuntime(8443): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-07 19:04:25.191: E/AndroidRuntime(8443): at dalvik.system.NativeStart.main(Native Method) 07-07 19:04:25.191: E/AndroidRuntime(8443): Caused by: java.lang.RuntimeException: Unable to destroy activity {com.xxxx.xxxx/com.xxxx.projecte1.webPush}: java.lang.NullPointerException 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.performDestroyActivity(ActivityThread.java:2693) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.performDestroyActivity(ActivityThread.java:2603) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.LocalActivityManager.dispatchDestroy(LocalActivityManager.java:622) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityGroup.onDestroy(ActivityGroup.java:85) 07-07 19:04:25.191: E/AndroidRuntime(8443): at com.xxxx.projecte1.TabBar_iOSActivity.onDestroy(TabBar_iOSActivity.java:417) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.performDestroyActivity(ActivityThread.java:2680) 07-07 19:04:25.191: E/AndroidRuntime(8443): ... 11 more

  • How to dispose off custom object from within custom membership provider

    - by IrfanRaza
    I have created my custom MembershipProvider. I have used an instance of the class DBConnect within this provider to handle database functions. Please look at the code below: public class SGIMembershipProvider : MembershipProvider { #region "[ Property Variables ]" private int newPasswordLength = 8; private string connectionString; private string applicationName; private bool enablePasswordReset; private bool enablePasswordRetrieval; private bool requiresQuestionAndAnswer; private bool requiresUniqueEmail; private int maxInvalidPasswordAttempts; private int passwordAttemptWindow; private MembershipPasswordFormat passwordFormat; private int minRequiredNonAlphanumericCharacters; private int minRequiredPasswordLength; private string passwordStrengthRegularExpression; private MachineKeySection machineKey; **private DBConnect dbConn;** #endregion ....... public override bool ChangePassword(string username, string oldPassword, string newPassword) { if (!ValidateUser(username, oldPassword)) return false; ValidatePasswordEventArgs args = new ValidatePasswordEventArgs(username, newPassword, true); OnValidatingPassword(args); if (args.Cancel) { if (args.FailureInformation != null) { throw args.FailureInformation; } else { throw new Exception("Change password canceled due to new password validation failure."); } } SqlParameter[] p = new SqlParameter[3]; p[0] = new SqlParameter("@applicationName", applicationName); p[1] = new SqlParameter("@username", username); p[2] = new SqlParameter("@password", EncodePassword(newPassword)); bool retval = **dbConn.ExecuteSP("User_ChangePassword", p);** return retval; } //ChangePassword public override void Initialize(string name, NameValueCollection config) { if (config == null) { throw new ArgumentNullException("config"); } ...... ConnectionStringSettings ConnectionStringSettings = ConfigurationManager.ConnectionStrings[config["connectionStringName"]]; if ((ConnectionStringSettings == null) || (ConnectionStringSettings.ConnectionString.Trim() == String.Empty)) { throw new ProviderException("Connection string cannot be blank."); } connectionString = ConnectionStringSettings.ConnectionString; **dbConn = new DBConnect(connectionString); dbConn.ConnectToDB();** ...... } //Initialize ...... } // SGIMembershipProvider I have instantiated dbConn object within Initialize() event. My problem is that how could i dispose off this object when object of SGIMembershipProvider is disposed off. I know the GC will do this all for me, but I need to explicitly dispose off that object. Even I tried to override Finalize() but there is no such overridable method. I have also tried to create destructor for SGIMembershipProvider. Can anyone provide me solution.

  • Issue accessing class variable from thread.

    - by James
    Hello, The code below is meant to take an arraylist of product objects as an input, spun thread for each product(and add the product to the arraylist 'products'), check product image(product.imageURL) availability, remove the products without images(remove the product from the arraylist 'products'), and return an arraylist of products with image available. package com.catgen.thread; import java.util.ArrayList; import java.util.Iterator; import java.util.List; import com.catgen.Product; import com.catgen.Utils; public class ProductFilterThread extends Thread{ private Product product; private List<Product> products = new ArrayList<Product>(); public ProductFilterThread(){ } public ProductFilterThread(Product product){ this.product = product; } public synchronized void addProduct(Product product){ System.out.println("Before add: "+getProducts().size()); getProducts().add(product); System.out.println("After add: "+getProducts().size()); } public synchronized void removeProduct(Product product){ System.out.println("Before rem: "+getProducts().size()); getProducts().remove(product); System.out.println("After rem: "+getProducts().size()); } public synchronized List<Product> getProducts(){ return this.products; } public synchronized void setProducts(List<Product> products){ this.products = products; } public void run(){ boolean imageExists = Utils.fileExists(this.product.ImageURL); if(!imageExists){ System.out.println(this.product.ImageURL); removeProduct(this.product); } } public List<Product> getProductsWithImageOnly(List<Product> products){ ProductFilterThread pft = null; try{ List<ProductFilterThread> threads = new ArrayList<ProductFilterThread>(); for(Product product: products){ pft = new ProductFilterThread(product); addProduct(product); pft.start(); threads.add(pft); } Iterator<ProductFilterThread> threadsIter = threads.iterator(); while(threadsIter.hasNext()){ ProductFilterThread thread = threadsIter.next(); thread.join(); } }catch(Exception e){ e.printStackTrace(); } System.out.println("Total returned products = "+getProducts().size()); return getProducts(); } } Calling statement: displayProducts = new ProductFilterThread().getProductsWithImageOnly(displayProducts); Here, when addProduct(product) is called from within getProductsWithImageOnly(), getProducts() returns the list of products, but that's not the case(no products are returned) when the method removeProduct() is called by a thread, because of which the products without images are never removed. As a result, all the products are returned by the module whether or not the contained products have images. What can be the problem here? Thanks in advance. James.

  • Activity gets killed while executing the camera intent

    - by BlackRider
    In my app I call the system camera to take a picture, and then handle the result in onActivityResult. You know, the usual. It used to work, but now my calling activity gets killed while I'm taking the picture. Specifically, onDestroy() is called on my activity right after I press the camera shutter. The photo does get taken & saved (I've checked that the file gets written on the SD card). After I accept the photo, instead of returning to the calling activity and invoking onActivityResult, the previous activity in the activity stack gets called. I see no exceptions in the logcat. My custom exception handler doesn't get called. If it matters, my app also includes a service that listens to GPS updates, but I unregister all the receivers in onPause(). Here's the call stack for MyCallingActivity.onDestroy(): Thread [<1> main] (Suspended (breakpoint at line 303 in NewPlaceDetailsActivity)) NewPlaceDetailsActivity.onDestroy() line: 303 ActivityThread.performDestroyActivity(IBinder, boolean, int, boolean) line: 2663 ActivityThread.handleDestroyActivity(IBinder, boolean, int, boolean) line: 2694 ActivityThread.access$2100(ActivityThread, IBinder, boolean, int, boolean) line: 117 BinderProxy(ActivityThread$H).handleMessage(Message) line: 968 ActivityThread$H(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 130 ActivityThread.main(String[]) line: 3687 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 507 ZygoteInit$MethodAndArgsCaller.run() line: 842 ZygoteInit.main(String[]) line: 600 NativeStart.main(String[]) line: not available [native method] This is how I start the camera activity, in case you're wondering: protected void startCamera() { createPhotoDirsIfNeeded(); String fileName = "temp.jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); m_capturedImageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); m_photoFileName = APP_PHOTO_PATH + "/" + DateFormat.format(DATE_FORMAT, Calendar.getInstance().getTime()) + ".jpg"; File picFile = new File(m_photoFileName); if(picFile.exists()) { picFile.delete(); } // start the camera activity Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(picFile)); startActivityForResult(intent, IntentHelper.REQUEST_TAKE_PHOTO); } How can I find out why does my activity get killed, AND removed from the stack instead of being created again?

  • TimeOuts with HttpWebRequest when running Selenium concurrently in .NET

    - by domsom
    I have a download worker that uses ThreadPool-threads to download files. After enhancing these to apply some Selenium tests to the downloaded files, I am constantly experiencing TimeOut-exceptions with the file downloaders and delays running the Selenium tests. More precisely: When the program starts, the download threads start downloading and a couple of pages are seamlessly processed via Selenium Shortly after, the first download threads start throwing TimeOut exceptions from HttpWebRequest. At the same time, commands stop flowing to Selenium (as observed in the SeleniumRC log), but the thread running Selenium is not getting any exception This situation holds as long as there are entries in the download list: new download threads are being started and terminate after receiving TimeOuts (without trying to lock Selenium) As soon as no more download threads are being started, Selenium starts receiving commands again and the threads waiting for the lock are processed sequentially as designed Now here's the download code: HttpWebRequest request = null; WebResponse response = null; Stream stream = null; StreamReader sr = null; try { request = (HttpWebRequest) WebRequest.Create(uri); request.ServicePoint.ConnectionLimit = MAX_CONNECTIONS_PER_HOST; response = request.GetResponse(); stream = response.GetResponseStream(); // Read the stream... } finally { if (request != null) request.Abort(); if (response != null) response.Close(); if (stream != null) { stream.Close(); stream.Dispose(); } if (sr != null) { sr.Close(); sr.Dispose(); } } And this is how Selenium is used afterwards in the same thread: lock(SeleniumLock) { selenium.Open(url); // Run some Selenium commands, but no selenium.stop() } Where selenium is a static variable that is initialized in the static constructor of the class (via selenium.start()). I assume I am running into the CLR connection limit, so I added these lines during initalization: ThreadPool.GetMaxThreads (out maxWorkerThreads, out maxCompletionPortThreads); HttpUtility.MAX_CONNECTIONS_PER_HOST = maxWorkerThreads; System.Net.ServicePointManager.DefaultConnectionLimit = maxWorkerThreads + 1; The + 1 is for the connection to the SeleniumRC, due to my guess that the Selenium client code also uses HttpWebRequest. It seems like I'm still running into some kind of deadlock - although the threads waiting for the Selenium lock do not hold any resources. Any ideas on how to get this working?

  • Why does WebSharingAppDemo-CEProviderEndToEnd sample still need a client db connection after scope c

    - by Don
    I'm researching a way to build an n-tierd sync solution. From the WebSharingAppDemo-CEProviderEndToEnd sample it seems almost feasable however for some reason, the app will only sync if the client has a live SQL db connection. Can some one explain what I'm missing and how to sync without exposing SQL to the internet? The problem I'm experiencing is that when I provide a Relational sync provider that has an open SQL connection from the client, then it works fine but when I provide a Relational sync provider that has a closed but configured connection string, as in the example, I get an error from the WCF stating that the server did not receive the batch file. So what am I doing wrong? SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(); builder.DataSource = hostName; builder.IntegratedSecurity = true; builder.InitialCatalog = "mydbname"; builder.ConnectTimeout = 1; provider.Connection = new SqlConnection(builder.ToString()); // provider.Connection.Open(); **** un-commenting this causes the code to work** //create anew scope description and add the appropriate tables to this scope DbSyncScopeDescription scopeDesc = new DbSyncScopeDescription(SyncUtils.ScopeName); //class to be used to provision the scope defined above SqlSyncScopeProvisioning serverConfig = new SqlSyncScopeProvisioning(); .... The error I get occurs in this part of the WCF code: public SyncSessionStatistics ApplyChanges(ConflictResolutionPolicy resolutionPolicy, ChangeBatch sourceChanges, object changeData) { Log("ProcessChangeBatch: {0}", this.peerProvider.Connection.ConnectionString); DbSyncContext dataRetriever = changeData as DbSyncContext; if (dataRetriever != null && dataRetriever.IsDataBatched) { string remotePeerId = dataRetriever.MadeWithKnowledge.ReplicaId.ToString(); //Data is batched. The client should have uploaded this file to us prior to calling ApplyChanges. //So look for it. //The Id would be the DbSyncContext.BatchFileName which is just the batch file name without the complete path string localBatchFileName = null; if (!this.batchIdToFileMapper.TryGetValue(dataRetriever.BatchFileName, out localBatchFileName)) { //Service has not received this file. Throw exception throw new FaultException<WebSyncFaultException>(new WebSyncFaultException("No batch file uploaded for id " + dataRetriever.BatchFileName, null)); } dataRetriever.BatchFileName = localBatchFileName; } Any ideas?

  • Between/Timerange LINQ

    - by dezza
    My intention here is to select all entries (Bookings) between "begin" (begin_prefix) and "end" (end_prefix) BUT! The important thing is: If I have a booking at 07:25-10:00 - you query for 09:00-10:00 it should still show the booking because it reserves the room until 10 no matter what .. So .. 07.25-10.00 booking means query for 09:00-10.00 still returns a list of bookings within 09:00-10.00 (which means 07.25-10.00 is included) public static List<booking> Today(DateTime begin, DateTime end) { try { IFormatProvider Culturez = new CultureInfo(ConfigurationManager.AppSettings["locale"].ToString(), true); DateTime begin_prefix = DateTime.ParseExact(begin.ToString(), "dd-MM-yyyy HH:mm:ss", Culturez); DateTime end_prefix = DateTime.ParseExact(end.ToString(), "dd-MM-yyyy HH:mm:ss", Culturez); dbDataContext db = new dbDataContext(); // gives bookings BEFORE begin_prefix (why?) IQueryable<booking> bQ = from b in db.bookings where begin_prefix >= b.Starts && b.Ends <= end_prefix && b.Ends > b.Starts && b.pointsbookings.Count > 0 select b; // ^gives bookings BEFORE begin_prefix (why?) List<booking> bL = bQ.ToList(); return bL; } catch (Exception) { throw; } } I've tried getting this right for some time now .. Seems everytime I correct it to something new, a new overlap or selection outside the two begin/end dates seem to appear :( UPDATE CRITERIA and SOURCE: Bookings has to be WITHIN "begin_prefix" and "end_prefix" or on the exact same time .. .. currently the above code gives me bookings BEFORE begin_prefix date, which is not intentioned! We're in 2011, I got bookings from 2010 as well! ** NEW!! UPDATED: This is what I have: SEARCH.START = BOOKING.START BOOKING.END <= SEARCH.END ... the problem comes up when .. BOOKING entry: 10:00(Start)-14:00(End) This means according to above: 08.59 = 10.00 (SEARCH.START = BOOKING.START) It will never include it. But it should, since this is the same room and the seats are booked individually!

  • UITableView: Mixing static and dynamic cells

    - by AlexR
    I am trying to mix dynamic and static cells in a grouped table view: I would like to get two sections with static cells at the top followed by a section of dynamic cells (please refer to the screenshot below). I have set the table view contents to static cells. I designed the static cells in Interface Builder and gave them identifiers related to their section and row: "section0static0", "section0static1", "section1static0" and "section1static1". I named the dynamic cell "section2dynamic". My delegate methods, in which I am trying to return the correct cell identifier (static or dynamic) are as follows: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { switch (section) { case 0: return 2; break; case 1: return 2; break; case 2: return 0; break; default: break; } return 0; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @""; if (indexPath.section <= 1) CellIdentifier = [NSString stringWithFormat:@"section%istatic%i",indexPath.section,indexPath.row]; else CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section]; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; return cell; } Edit Based on AppleFreak's advice I have changed my code as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell; if (indexPath.section <= 1) { // section <= 1 indicates static cells cell = [super tableView:tableView cellForRowAtIndexPath:indexPath]; } else { // section > 1 indicates dynamic cells CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section]; cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; } return cell; } However, my app crashes with error message Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:' for section 0 and row 0. The cell returned from cell = [super tableView:tableView cellForRowAtIndexPath:indexPath] for section 0 and row 0 is nil. What is wrong with my code? Could there be any problems with my outlets? I haven't set any outlets because I am subclassing UITableViewController and supposedly do not any outlets for tableview to be set (?). Any suggestions on how to better do it?

  • .NET threading: how can I capture an abort on an unstarted thread?

    - by Groxx
    I have a chunk of threads I wish to run in order, on an ASP site running .NET 2.0 with Visual Studio 2008 (no idea how much all that matters, but there it is), and they may have aborted-clean-up code which should be run regardless of how far through their task they are. So I make a thread like this: Thread t = new Thread(delegate() { try { /* do things */ System.Diagnostics.Debug.WriteLine("try"); } catch (ThreadAbortException) { /* cleanup */ System.Diagnostics.Debug.WriteLine("catch"); } }); Now, if I wish to abort the set of threads part way through, the cleanup may still be desirable later on down the line. Looking through MSDN implies you can .Abort() a thread that has not started, and then .Start() it, at which point it will receive the exception and perform normally. Or you can .Join() the aborted thread to wait for it to finish aborting. Presumably you can combine them. http://msdn.microsoft.com/en-us/library/ty8d3wta(v=VS.80).aspx To wait until a thread has aborted, you can call the Join method on the thread after calling the Abort method, but there is no guarantee the wait will end. If Abort is called on a thread that has not been started, the thread will abort when Start is called. If Abort is called on a thread that is blocked or is sleeping, the thread is interrupted and then aborted. Now, when I debug and step through this code: t.Abort(); // ThreadState == Unstarted | AbortRequested t.Start(); // throws ThreadStartException: "Thread failed to start." // so I comment it out, and t.Join(); // throws ThreadStateException: "Thread has not been started." At no point do I see any output, nor do any breakpoints on either the try or catch block get reached. Oddly, ThreadStartException is not listed as a possible throw of .Start(), from here: http://msdn.microsoft.com/en-us/library/a9fyxz7d(v=VS.80).aspx (or any other version) I understand this could be avoided by having a start parameter, which states if the thread should jump to cleanup code, and foregoing the Abort call (which is probably what I'll do). And I could .Start() the thread, and then .Abort() it. But as an indeterminate amount of time may pass between .Start and .Abort, I'm considering it unreliable, and the documentation seems to say my original method should work. Am I missing something? Is the documentation wrong? edit: ow. And you can't call .Start(param) on a non-parameterized Thread(Start). Is there a way to find out if a thread is parameterized or not, aside from trial and error? I see a private m_Delegate, but nothing public...

  • .NET XmlSerializer fails with List<T>

    - by Redshirt
    I'm using a singleton class to save all my settings info. It's first utilized by calling Settings.ValidateSettings(@"C:\MyApp"). The problem I'm having is that 'List Contacts' is causing the xmlserializer to fail to write the settings file, or to load said settings. If I comment out the List<T> then I have no problems saving/loading the xml file. What am I doing wrong? // The actual settings to save public class MyAppSettings { public bool FirstLoad { get; set; } public string VehicleFolderName { get; set; } public string ContactFolderName { get; set; } public List<ContactInfo> Contacts { get { if (contacts == null) contacts = new List<ContactInfo>(); return contacts; } set { contacts = value; } } private List<ContactInfo> contacts; } // The class in which the settings are manipulated public static class Settings { public static string SettingPath; private static MyAppSettings instance; public static MyAppSettings Instance { get { if (instance == null) instance = new MyAppSettings(); return instance; } set { instance = value; } } public static void InitializeSettings(string path) { SettingPath = Path.GetFullPath(path + "\\MyApp.xml"); if (File.Exists(SettingPath)) { LoadSettings(); } else { Instance.FirstLoad = true; Instance.VehicleFolderName = "Cars"; Instance.ContactFolderName = "Contacts"; SaveSettingsFile(); } } // load the settings from the xml file private static void LoadSettings() { XmlSerializer ser = new XmlSerializer(typeof(MyAppSettings)); TextReader reader = new StreamReader(SettingPath); Instance = (MyAppSettings)ser.Deserialize(reader); reader.Close(); } // Save the settings to the xml file public static void SaveSettingsFile() { XmlSerializer ser = new XmlSerializer(typeof(MyAppSettings)); TextWriter writer = new StreamWriter(SettingPath); ser.Serialize(writer, Settings.Instance); writer.Close(); } public static bool ValidateSettings(string initialFolder) { try { Settings.InitializeSettings(initialFolder); } catch (Exception e) { return false; } // Do some validation logic here return true; } } // A utility class to contain each contact detail public class ContactInfo { public string ContactID; public string Name; public string PhoneNumber; public string Details; public bool Active; public int SortOrder; }

  • Hibernate @Transactional not starting transaction

    - by rhinds
    I have a web app using Hibernate, and I am attempting to persist some data, but it is failing to persist within a Transaction despite using the @Transactional annotation. My service class is as follows: @Service("profileService") public class ProfileService { private EntityManager entityManager; @Autowired private AccountService accountService; @Autowired private ProfileDAOImpl profileDao; @PersistenceContext public void setEntityManager(EntityManager em) { this.entityManager = em; } @Transactional public void addConnectionToAccount(SocialConnection sc) { entityManager.persist(sc); } } The addConnectionToAccount() method is being called from another Spring bean in a normal method, and the ProfileService class is currently being injected there: public class HibernateConnectionRepository implements ConnectionRepository { @Inject private ProfileService profileService; @Override @Transactional public void addConnection(SocialConnection sc) { try { profileService.addConnectionToAccount(accountId, sc); } catch (Exception e) { e.printStackTrace(); } } I tried putting the @Transactional annotation on the calling method in the vain hope that it might make a difference but nothing. Previously I have experienced problems like this its been because the object being persisted does not satisfy table restrictions (such as non-nullable columns as null) or because the method is being called from within the same class and the calling method is not Transactional, but neither of those are the case here.. Any ideas? it just fails silently, the logs are as follows: 2012-03-26 22:25:04,702 [http-bio-8085-exec-9] DEBUG com.mchange.v2.resourcepool.BasicResourcePool - trace com.mchange.v2.resourcepool.BasicResourcePool@1bc25c8 [managed: 3, unused: 2, excluded: 0] (e.g. com.mchange.v2.c3p0.impl.NewPooledConnection@e5b006) 2012-03-26 22:25:04,710 [http-bio-8085-exec-9] DEBUG org.hibernate.SQL - select SEQ_COUNT from SEQUENCE where SEQ_NAME = 'PO_SEQ' for update 2012-03-26 22:25:04,711 [http-bio-8085-exec-9] DEBUG org.hibernate.SQL - update SEQUENCE set SEQ_COUNT = ? where SEQ_COUNT = ? and SEQ_NAME = 'PO_SEQ' 2012-03-26 22:25:04,723 [http-bio-8085-exec-9] DEBUG com.mchange.v2.resourcepool.BasicResourcePool - trace com.mchange.v2.resourcepool.BasicResourcePool@1bc25c8 [managed: 3, unused: 2, excluded: 0] (e.g. com.mchange.v2.c3p0.impl.NewPooledConnection@e5b006) 2012-03-26 22:25:04,723 [http-bio-8085-exec-9] DEBUG org.hibernate.event.internal.AbstractSaveEventListener - Generated identifier: 2200, using strategy: org.hibernate.id.MultipleHiLoPerTableGenerator UPDATE Also wanted to mention that the HibernateConnectionRepository bean is not annotated and is actually being configured in an @Configuration class (if this makes any difference? not used @Configuration classes much). The method to create the bean is as follows: @Bean @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES) public ConnectionRepository connectionRepository() { Authentication authentication = SecurityContextHolder.getContext().getAuthentication(); if (authentication == null) { throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in"); } ApplicationUser user = (ApplicationUser) authentication.getPrincipal(); return usersConnectionRepository().createConnectionRepository(String.valueOf(user.getAccountId())); } The bean is scoped to the logged in user, but may also be created multiple times for each user..
