  • Updating an application OTA

    - by Bostjan
    I'm developing an application that will be available from a website (market probably as well). The problem I'm having at the moment is how to handle the updates to the app. I know how to check the version against the current one and I know if I need to update it. Question is...how? Is there a way I can download an APK from the website and start the install process? The user will have to confirm of course, but I just want to be able to start it for him. At the moment I'm doing this: private void doUpgrade() { // TODO Auto-generated method stub Builder builder = new AlertDialog.Builder(this); builder.setTitle(getString(R.string.upgrade)); builder.setIcon(R.drawable.help); builder.setMessage(getString(R.string.needUpgrade)); builder.setPositiveButton(getString(R.string.ok), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub Map<String, String> data = new HashMap<String, String>(); try { HttpResponse re = Registration.doPost("http://www.android-town.com/appRelease/AndroidTown.apk",data); int statusCode = re.getStatusLine().getStatusCode(); closeApp(); } catch (ClientProtocolException e) { e.printStackTrace(); Toast.makeText(getApplicationContext(), getString(R.string.noURLAccess), Toast.LENGTH_SHORT).show(); closeApp(); } catch (IOException e) { e.printStackTrace(); Toast.makeText(getApplicationContext(), getString(R.string.noURLAccess), Toast.LENGTH_SHORT).show(); closeApp(); } } }); builder.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub dialog.cancel(); closeApp(); } }); builder.show(); } But it doesn't really do anything...should I open a webView with the URL? A new runnable thread? Any other way? Please help :) Cheers

  • How to programmatically generate WSDL from WCF service (Integration Testing)

    - by David Christiansen
    Hi All, I am looking to write some integration tests to compare the WSDL generated by WCF services against previous (and published) versions. This is to ensure the service contracts don't differ from time of release. I would like my tests to be self contained and not rely on any external resources such as hosting on IIS. I am thinking that I could recreate my IIS hosting environment within the test with something like... using (ServiceHost host = new ServiceHost(typeof(NSTest.HelloNS), new Uri("http://localhost:8000/Omega"))) { host.AddServiceEndpoint(typeof(NSTest.IMy_NS), new BasicHttpBinding(), "Primary"); ServiceMetadataBehavior behavior = new ServiceMetadataBehavior(); behavior.HttpGetEnabled = true; host.Description.Behaviors.Add(behavior); host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexHttpBinding(), "mex"); host.Open(); } Does anyone else have any better ideas?

  • Why does this work?

    - by jsoldi
    I was googling trying to find a way to call Control.DataBindings.Add without using a string literal but getting the property name from the property itself, which I think would be less error prone, at least for my particular case, since I normally let Visual Studio do the renaming when renaming a property. So my code would look something like DataBindings.Add(GetName(myInstance.myObject)... instead of DataBindings.Add("myObject".... So I found this: static string GetName<T>(T item) where T : class { var properties = typeof(T).GetProperties(); if (properties.Length != 1) throw new Exception("Length must be 1"); return properties[0].Name; } That would be called, assuming I have a property called One, this way: string name = GetName(new { this.One }); which would give me "One". I have no clue why does it work and whether is safe to use it or not. I don't even know what that new { this.One } means. And I don't know on which case could it happens that properties.Length is not 1. By the way, I just tested to rename my property One to Two and Visual Studio turned new { this.One } into new { One = this.Two }, which when used with the GetName function gave me "One", which make the whole thing useless since the name I would be passing to Control.DataBindings.Add would be still "One" after renaming the property.

  • How to remove multiple instances and just have one instance while multiple function calls in php ?

    - by Rachel
    public function getHelperInstance() { $user = new Helper(); $user->set($result['data']); return $user; } I am calling getHelper() class multiple times and if $user is not empty than am calling getHelperInstance(), now in my case getHelperInstance() always creates a new instance of Helper() class and so every time I call getHelperInstance() function am creating a new instance of Helper() so is there any way where can I can just create one instance of Helper() and use it multiple times instead of creating a new instance everytime. Any suggestions !!! public function getHelper() { $user = array(); if (!empty($user)) { $user = $this->getHelperInstance(); } return $user; }

  • Best way to return result from business layer to presentation layer when using LINQ-to-SQL

    - by samsur
    I have a business layer that has DTOs that are used in the presentation layer. This application uses entity framework. Here is an example of a class called RoleDTO: public class RoleDTO { public Guid RoleId { get; set; } public string RoleName { get; set; } public string RoleDescription { get; set; } public int? OrganizationId { get; set; } } In the BLL I want to have a method that returns a list of DTO. I would like to know which is the better approach: returning IQueryable or list of DTOs. Although I feel that returning IQueryable is not a good idea because the connection needs to be open. Here are the 2 different methods using the different approaches: First approach public class RoleBLL { private servicedeskEntities sde; public RoleBLL() { sde = new servicedeskEntities(); } public IQueryable<RoleDTO> GetAllRoles() { IQueryable<RoleDTO> role = from r in sde.Roles select new RoleDTO() { RoleId = r.RoleID, RoleName = r.RoleName, RoleDescription = r.RoleDescription, OrganizationId = r.OrganizationId }; return role; } Note: in the above method the DataContext is a private attribute and set in the constructor, so that the connection stays opened. Second approach public static List<RoleDTO> GetAllRoles() { List<RoleDTO> roleDTO = new List<RoleDTO>(); using (servicedeskEntities sde = new servicedeskEntities()) { var roles = from pri in sde.Roles select new { pri.RoleID, pri.RoleName, pri.RoleDescription }; //Add the role entites to the DTO list and return. This is necessary as anonymous types can be returned acrosss methods foreach (var item in roles) { RoleDTO roleItem = new RoleDTO(); roleItem.RoleId = item.RoleID; roleItem.RoleDescription = item.RoleDescription; roleItem.RoleName = item.RoleName; roleDTO.Add(roleItem); } return roleDTO; } } Please let me know, if there is a better approach.

  • What is the best way to handle the Connections to MySql from c#

    - by srk
    I am working on a c# application which connects to MySql server. There are about 20 functions which will connect to database. This application will be deployed in 200 over machines. I am using the below code to connect to my database which is identical for all the functions. The problem is, i can some connections were not closed and still alive when deployed in 200 over machines. Connection String : <add key="Con_Admin" value="server=test-dbserver; database=test_admindb; uid=admin; password=1Password; Use Procedure Bodies=false;" /> Declaration of the connection string Globally in application [Global.cs] : public static MySqlConnection myConn_Instructor = new MySqlConnection(ConfigurationSettings.AppSettings["Con_Admin"]); Function to query database : public static DataSet CheckLogin_Instructor(string UserName, string Password) { DataSet dsValue = new DataSet(); //MySqlConnection myConn = new MySqlConnection(ConfigurationSettings.AppSettings["Con_Admin"]); try { string Query = "SELECT accounts.str_nric AS Nric, accounts.str_password AS `Password`," + " FROM accounts " + " WHERE accounts.str_nric = '" + UserName + "' AND accounts.str_password = '" + Password + "\'"; MySqlCommand cmd = new MySqlCommand(Query, Global.myConn_Instructor); MySqlDataAdapter da = new MySqlDataAdapter(); if (Global.myConn_Instructor.State == ConnectionState.Closed) { Global.myConn_Instructor.Open(); } cmd.ExecuteScalar(); da.SelectCommand = cmd; da.Fill(dsValue); Global.myConn_Instructor.Close(); } catch (Exception ex) { Global.myConn_Instructor.Close(); ExceptionHandler.writeToLogFile(System.Environment.NewLine + "Target : " + ex.TargetSite.ToString() + System.Environment.NewLine + "Message : " + ex.Message.ToString() + System.Environment.NewLine + "Stack : " + ex.StackTrace.ToString()); } return dsValue; }

  • Inserting variables into a query string - it won't work!

    - by Jonesy
    Basically i have a query string that when i hardcode in the catalogue value its fine. when I try adding it via a variable it just doesn't pick it up. This works: Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=WaspTrackAsset_NROI;User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';") This doesn't: Public Sub GetWASPAcr() connection.Open() Dim dt As New DataTable() Dim username As String = HttpContext.Current.User.Identity.Name Dim sqlCmd As New SqlCommand("SELECT WASPDatabase FROM dbo.aspnet_Users WHERE UserName = '" & username & "'", connection) Dim sqlDa As New SqlDataAdapter(sqlCmd) sqlDa.Fill(dt) If dt.Rows.Count > 0 Then For i As Integer = 0 To dt.Rows.Count - 1 If dt.Rows(i)("WASPDatabase") Is DBNull.Value Then WASP = "" Else WASP = "WaspTrackAsset_" + dt.Rows(i)("WASPDatabase") End If Next End If connection.Close() End Sub Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=" & WASP & ";User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';") When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI" Any idea's why?

  • PendingIntent sent from a notication.

    - by totem
    Hi, What im trying to accomplish is to send a notification through the notification manager that once clicked will do something in the application only if its currently running. i have tried to use: notification.contentIntent = PendingIntent.getActivity(this, nNotificationCounter, Someintent, PendingIntent.FLAG_NO_CREATE) Which allways caused an exception once trying to use the notify. I switched to: Notification notification = new Notification(icon, tickerText, when); RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.some_notification); contentView.setTextViewText(R.id.title, sTitle); contentView.setTextViewText(R.id.text, sText); notification.contentView = contentView; notification.defaults |= Notification.DEFAULT_SOUND; notification.number = nNotificationCounter; Intent notificationIntent = new Intent(this, MainWindow.class).setAction(ACTION_RESET_MESSGE_COUNTER); notification.contentIntent = PendingIntent.getBroadcast(this, nNotificationCounter, notificationIntent, 0); and although this code doesn't cause an exception. it doesnt call my BroadcastReceiver which is defined as follows: public class IncomingReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(ACTION_RESET_MESSGE_COUNTER)) { System.out.println("GOT THE INTENT"); return; } } } and set in the onCreate: IntentFilter filter = new IntentFilter(ACTION_RESET_MESSGE_COUNTER); IncomingReceiver receiver = new IncomingReceiver(); context.registerReceiver(receiver, filter); Does anyone see something wrong with the code? Or how would i go about to get messages when the notification is clicked, but not create any activity if it isn't already created. edit: added the intent creation and notification creation. Thanks, Tom

  • Best evidence to offer a sandboxed appdomain for a C# evaluator.

    - by scope-creep
    I have a c# evaluator which uses the (I think) the .Net 4 new simplified sandboxed appdomain model to host the c# assembly, with remoting doing the rest. The call to create the appdomain is Evidence ev = new Evidence(); ev.AddHostEvidence(new Zone(SecurityZone.Trusted)); PermissionSet pset = SecurityManager.GetStandardSandbox(ev); AppDomainSetup ads = new AppDomainSetup(); ads.ApplicationBase = "C:\\Sandbox"; // Create the sandboxed domain. AppDomain sandbox = AppDomain.CreateDomain( "Sandboxed Domain", ev, ads, pset, null); The c# eval is embedded in a server app, but I don't want give the sandbox to much control unless it bo bo's the caller. What i'm looking for is regarding some clarification as to what to provide as Evidence from the caller. I'm looking for advice and guidance. Any help would be appreciated.

  • Correct way to close database connection in event of exception.

  • Failing to add different items in combobox on dynamic radiobutton click

    - by Steven Wilson
    I am working on radiobuttons and combobox in my wpf App. Although I am a C++ developer, I recently moved to C#. My app deals with dynamic generation of the above mentioned components. Basically I have created 4 dynamic radiobuttons in my app and on clicking each, i should should add different items to my combobox. Here is the code: XAML: <ItemsControl ItemsSource="{Binding Children}"> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel Orientation="Vertical" > <RadioButton Content="{Binding RadioBase}" Margin="0,10,0,0" IsChecked="{Binding BaseCheck}" GroupName="SlotGroup" Height="15" Width="80" HorizontalAlignment="Center" VerticalAlignment="Center"/> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <ComboBox Visibility="{Binding IsRegisterItemsVisible}" ItemsSource="{Binding RegComboList}" SelectedItem="{Binding SelectedRegComboList, Mode=TwoWay}" SelectedIndex="0" /> FPGARadioWidgetViewModel Class: public ObservableCollection<FPGAViewModel> Children { get; set; } public FPGARadioWidgetViewModel() { Children = new ObservableCollection<FPGAViewModel>(); Children.Add(new FPGAViewModel() { RadioBase = "Base 0x0", ID = 0 }); Children.Add(new FPGAViewModel() { RadioBase = "Base 0x40", ID = 1 }); Children.Add(new FPGAViewModel() { RadioBase = "Base 0x80", ID = 2 }); Children.Add(new FPGAViewModel() { RadioBase = "Base 0xc0", ID = 3 }); } FPGAViewModel Class: private bool sBaseCheck; public bool BaseCheck { get { return this.sBaseCheck; } set { this.sBaseCheck = value; AddComboItems(); this.OnPropertyChanged("BaseCheck"); } } private ObservableCollection<string> _RegComboList; public ObservableCollection<string> RegComboList { get { return _RegComboList; } set { _RegComboList = value; OnPropertyChanged("RegComboList"); } } private void AddComboItems() { int baseRegister = 0x40 * ID; ObservableCollection<string> combo = new ObservableCollection<string>(); for (int i = 0; i < 0x40; i++) { int reg = (i * 8) + baseRegister; combo[i] = "0x" + reg.ToString("X"); } RegComboList = new ObservableCollection<String>(combo); OnPropertyChanged("RegComboList"); } private bool isRegisterItemsVisible = false; public bool IsRegisterItemsVisible { get { return isRegisterItemsVisible; } set { isRegisterItemsVisible = value; OnPropertyChanged("IsRegisterItemsVisible"); OnPropertyChanged("RegComboList"); } } If you notice, on clicking a particular radiobutton, it should add items with different value in combobox based on ID. It has to be made sure that on clicking any radiobutton only the items of that should be added and previous content of combobox should be cleared. I am trying to do the same thing using my above code but nothing seems to appear in combobox when i debug. Please help :)

  • Add a listener inside or outside get method

  • Nhibernate Migration from 1.0.2.0 to 2.1.2 and many-to-one save problems

    - by Meska
    Hi, we have an old, big asp.net application with nhibernate, which we are extending and upgrading some parts of it. NHibernate that was used was pretty old ( 1.0.2.0), so we decided to upgrade to ( 2.1.2) for the new features. HBM files are generated through custom template with MyGeneration. Everything went quite smoothly, except for one thing. Lets say we have to objects Blog and Post. Blog can have many posts, so Post will have many-to-one relationship. Due to the way that this application operates, relationship is done not through primary keys, but through Blog.Reference column. Sample mapings and .cs files: <?xml version="1.0" encoding="utf-8" ?> <id name="Id" column="Id" type="Guid"> <generator class="assigned"/> </id> <property column="Reference" type="Int32" name="Reference" not-null="true" /> <property column="Name" type="String" name="Name" length="250" /> </class> <?xml version="1.0" encoding="utf-8" ?> <id name="Id" column="Id" type="Guid"> <generator class="assigned"/> </id> <property column="Reference" type="Int32" name="Reference" not-null="true" /> <property column="Name" type="String" name="Name" length="250" /> <many-to-one name="Blog" column="BlogId" class="SampleNamespace.BlogEntity,SampleNamespace" property-ref="Reference" /> </class> And class files class BlogEntity { public Guid Id { get; set; } public int Reference { get; set; } public string Name { get; set; } } class PostEntity { public Guid Id { get; set; } public int Reference { get; set; } public string Name { get; set; } public BlogEntity Blog { get; set; } } Now lets say that i have a Blog with Id 1D270C7B-090D-47E2-8CC5-A3D145838D9C and with Reference 1 In old nhibernate such thing was possible: //this Blog already exists in database BlogEntity blog = new BlogEntity(); blog.Id = Guid.Empty; blog.Reference = 1; //Reference is unique, so we can distinguish Blog by this field blog.Name = "My blog"; //this is new Post, that we are trying to insert PostEntity post = new PostEntity(); post.Id = Guid.NewGuid(); post.Name = "New post"; post.Reference = 1234; post.Blog = blog; session.Save(post); However, in new version, i get an exception that cannot insert NULL into Post.BlogId. As i understand, in old version, for nhibernate it was enough to have Blog.Reference field, and it could retrieve entity by that field, and attach it to PostEntity, and when saving PostEntity, everything would work correctly. And as i understand, new NHibernate tries only to retrieve by Blog.Id. How to solve this? I cannot change DB design, nor can i assign an Id to BlogEntity, as objects are out of my control (they come prefilled as generic "ojbects" like this from external source)

  • Java Socket Returns True

    - by ikurtz
    I hope you can help. Im fairly new to progamming and Im playing around with java Sockets. The problem is the code below. for some reason commSocket = new Socket(hostName, portNumber); is returning true even when it has not connected with the server (server not implemented yet!). Any ideas regarding this situation? For hostName Im passing my local machine IP and for port a manually selected port. public void networkConnect(String hostName, int portNumber){ try { networkConnected = false; netMessage = "Attempting Connection"; NetworkMessage networkMessage = new NetworkMessage(networkConnected, netMessage); commSocket = new Socket(hostName, portNumber); // this returns true!! System.out.println(commSocket.isConnected()); networkConnected = true; netMessage = "Connected: "; System.out.println("hellooo"); } catch (UnknownHostException e){ System.out.println(e.getMessage()); } catch (IOException e){ System.out.println(e.getMessage()); } } Many thanks. EDIT: new Socket(.., ..); is blocking isnt it? i thought in that case if that was processed without exceptions then we have a true connection?

  • Excel - referenced values via OleDB from .Net client

    - by ho
    I'm trying to read an Excel file (.xls, I think Excel 2003 compatible) via OleDB, but it fails to get the values for referenced fields.

I can get around this by automating Excel instead, but would prefer not to have to use Excel automation so wondering if anyone knows how to do it.

    Hello, I have these code: Mypage.cs string[] strParameterName = new string[2] {"?FirstName", "?LastName"}; string[] strParameterValue = new string[2] {"Josef", "Stalin"}; MyConnection.MySqlLink(strConnection, strCommand, strParameterName, strParameterValue, dtTable); Myclass.cs public static void MySqlLink(string strConnection, string strCommand, string[] strParameterName, string[] strParameterValue, DataTable dtTable) { dtTable.Clear(); MySqlConnection MyConnection = new MySqlConnection(strConnection); MySqlCommand MyCommand = new MySqlCommand(strCommand, MyConnection); for (int i = 0; i < strParameterName.Length; i++) { MyCommand.Parameters.AddWithValue(strParameterName[i].ToString(), strParameterValue[i].ToString()); } MySqlDataAdapter MyDataAdapter = new MySqlDataAdapter(MyCommand); MyDataAdapter.Fill(dtTable); } And then my Sql Command will be something like "SELECT * FROM MyTable WHERE FirstName=?FirstName AND LastName=?LastName" As you can see, I am using arrays for the Parameter Name and Parameter Value and they both have to "match" with each other and ofcourse the Sql Command. Someone recommended to me that I use .NET "Dictionary" instead of arrays. Now I have never used that before. Can someone show me a relative example of how I am to use .NET Dictionary here?

  • Windows Phone period task, function not executing

    - by Special K.
    I'm trying to execute a code (to parse an XML to be more precisely, and after that I'll toast message the user with some new info's), but the class function AccDetailsDownloaded is not executed (is simply skipped), also the memory usage is ~2mb out of 6, here is my code: if (task is PeriodicTask) { getData(); } else { getData(); } // If debugging is enabled, launch the agent again in one minute. #if DEBUG_AGENT ScheduledActionService.LaunchForTest(task.Name, TimeSpan.FromSeconds(60)); #endif // Call NotifyComplete to let the system know the agent is done working. NotifyComplete(); } public void getData() { var settings = IsolatedStorageSettings.ApplicationSettings; string url = "http://example.com/example.xml"; if (!System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable()) { MessageBox.Show("No network connection available!"); return; } // start loading XML-data WebClient downloader = new WebClient(); Uri uri = new Uri(url, UriKind.Absolute); downloader.DownloadStringCompleted += new DownloadStringCompletedEventHandler(AccDetailsDownloaded); downloader.DownloadStringAsync(uri); string toastTitle = ""; toastTitle = "Periodic "; string toastMessage = "Mem usage: " + DeviceStatus.ApplicationPeakMemoryUsage + "/" + DeviceStatus.ApplicationMemoryUsageLimit; // Launch a toast to show that the agent is running. // The toast will not be shown if the foreground application is running. ShellToast toast = new ShellToast(); toast.Title = toastTitle; toast.Content = toastMessage; toast.Show(); } void AccDetailsDownloaded(object sender, DownloadStringCompletedEventArgs e) { if (e.Result == null || e.Error != null) { MessageBox.Show("There was an error downloading the XML-file!"); } else { string toastTitle = ""; toastTitle = "Periodic "; string toastMessage = "Mem usage: " + DeviceStatus.ApplicationPeakMemoryUsage + "/" + DeviceStatus.ApplicationMemoryUsageLimit; // Launch a toast to show that the agent is running. // The toast will not be shown if the foreground application is running. ShellToast toast = new ShellToast(); toast.Title = toastTitle; toast.Content = toastMessage; toast.Show(); } } Thank you.

  • Why is a .net generic dictionary so big

    - by thefroatgt
    I am serializing a generic dictionary in VB.net and I am very surprised that it is about 1.3kb with a single item. Am I doing something wrong, or is there something else I should be doing? I have a large number of dictionaries and it is killing me to send them all across the wire. The code I use for serialization is Dim dictionary As New Dictionary(Of Integer, Integer) Dim stream As New MemoryStream Dim bformatter As New BinaryFormatter() dictionary.Add(1, 1) bformatter.Serialize(stream, dictionary) Dim len As Long = stream.Length

  • For loop index out of range ArgumentOutOfRangeException when multithreading

    - by Lirik
    I'm getting some strange behavior... when I iterate over the dummyText List in the ThreadTest method I get an index out of range exception (ArgumentOutOfRangeException), but if I remove the threads and I just print out the text, then everything works fine. This is my main method: public static Object sync = new Object(); static void Main(string[] args) { ThreadTest(); Console.WriteLine("Press any key to continue."); Console.ReadKey(); } This method throws the exception: private static void ThreadTest() { Console.WriteLine("Running ThreadTest"); Console.WriteLine("Running ThreadTest"); List<String> dummyText = new List<string>() { "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten"}; for (int i = 0; i < dummyText.Count; i++) { Thread t = new Thread(() => PrintThreadName(dummyText[i])); // <-- Index out of range?!? t.Name = ("Thread " + (i)); t.IsBackground = true; t.Start(); } } private static void PrintThreadName(String text) { Random rand = new Random(DateTime.Now.Millisecond); while (true) { lock (sync) { Console.WriteLine(Thread.CurrentThread.Name + " running " + text); Thread.Sleep(1000+rand.Next(0,2000)); } } } This does not throw the exception: private static void ThreadTest() { Console.WriteLine("Running ThreadTest"); List<String> dummyText = new List<string>() { "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten"}; for (int i = 0; i < dummyText.Count; i++) { Console.WriteLine(dummyText[i]); // <-- No exception here } } Does anybody know why this is happening?
