  • How to create a RESTful web service in asp.net?

    - by jonhobbs
    Hi Guys, I simply want to create a fairly basic REST service, so that I can expose some of the data in my asp.net/SQL server application to the outside works, like this..... http://domain.com/api/offices - would return an xml set of office locations. http://domain.com/api/offices/15 - would return all the details of office 15. It's all fairly standard stuff (including basic authentication) but there seem to be several ways to achieve this using Microsoft technologies and I don't really know where to start. These seem to be the options... 1) WCF 2) ASP.NET MVC 3) ADO.NET Data Services 4) Rest Starter Kit project templates? Which of these is the easiest and most "up-to-date" solution to creating a web service?

  • Simplest way to flatten document to a view in RavenDB

    - by degorolls
    Given the following classes: public class Lookup { public string Code { get; set; } public string Name { get; set; } } public class DocA { public string Id { get; set; } public string Name { get; set; } public Lookup Currency { get; set; } } public class ViewA // Simply a flattened version of the doc { public string Id { get; set; } public string Name { get; set; } public string CurrencyName { get; set; } // View just gets the name of the currency } I can create an index that allows client to query the view as follows: public class A_View : AbstractIndexCreationTask<DocA, ViewA> { public A_View() { Map = docs => from doc in docs select new ViewA { Id = doc.Id, Name = doc.Name, CurrencyName = doc.Currency.Name }; Reduce = results => from result in results group on new ViewA { Id = result.Id, Name = result.Name, CurrencyName = result.CurrencyName } into g select new ViewA { Id = g.Key.Id, Name = g.Key.Name, CurrencyName = g.Key.CurrencyName }; } } This certainly works and produces the desired result of a view with the data transformed to the structure required at the client application. However, it is unworkably verbose, will be a maintenance nightmare and is probably fairly inefficient with all the redundant object construction. Is there a simpler way of creating an index with the required structure (ViewA) given a collection of documents (DocA)? FURTHER INFORMATION The issue appears to be that in order to have the index hold the data in the transformed structure (ViewA), we have to do a Reduce. It appears that a Reduce must have both a GROUP ON and a SELECT in order to work as expected so the following are not valid: INVALID REDUCE CLAUSE 1: Reduce = results => from result in results group on new ViewA { Id = result.Id, Name = result.Name, CurrencyName = result.CurrencyName } into g select g.Key; This produces: System.InvalidOperationException: Variable initializer select must have a lambda expression with an object create expression Clearly we need to have the 'select new'. INVALID REDUCE CLAUSE 2: Reduce = results => from result in results select new ViewA { Id = result.Id, Name = result.Name, CurrencyName = result.CurrencyName }; This prduces: System.InvalidCastException: Unable to cast object of type 'ICSharpCode.NRefactory.Ast.IdentifierExpression' to type 'ICSharpCode.NRefactory.Ast.InvocationExpression'. Clearly, we also need to have the 'group on new'. Thanks for any assistance you can provide. (Note: removing the type (ViewA) from the constructor calls has no effect on the above)

  • How do I display non-normalized data in a hierarchical structure?

    - by rofly
    My issue is that I want to display data in a hierarchal structure as so: Democrat County Clerk Candidate 1 Candidate 2 Magistrate Candidate 1 Candidate 2 Candidate 3 But I'm retrieving the dataset like this: Party | Office | Candidate Democrat | County Clerk | Candidate 1 Democrat | County Clerk | Candidate 2 Democrat | Magistrate | Candidate 1 Democrat | Magistrate | Candidate 2 Democrat | Magistrate | Candidate 3 I planned on using nested repeaters, but I need a distinct value of Party, and then distinct values of office name within that party in order to do it. Are there any .NET functions to easily do what I'm attempting to? Would there be a better way of displaying the information other than repeaters? Thanks in advance!

  • Reducer getting fewer records than expected

    - by sathishs
    We have a scenario of generating unique key for every single row in a file. we have a timestamp column but the are multiple rows available for a same timestamp in few scenarios. We decided unique values to be timestamp appended with their respective count as mentioned in the below program. Mapper will just emit the timestamp as key and the entire row as its value, and in reducer the key is generated. Problem is Map outputs about 236 rows, of which only 230 records are fed as an input for reducer which outputs the same 230 records. public class UniqueKeyGenerator extends Configured implements Tool { private static final String SEPERATOR = "\t"; private static final int TIME_INDEX = 10; private static final String COUNT_FORMAT_DIGITS = "%010d"; public static class Map extends Mapper<LongWritable, Text, Text, Text> { @Override protected void map(LongWritable key, Text row, Context context) throws IOException, InterruptedException { String input = row.toString(); String[] vals = input.split(SEPERATOR); if (vals != null && vals.length >= TIME_INDEX) { context.write(new Text(vals[TIME_INDEX - 1]), row); } } } public static class Reduce extends Reducer<Text, Text, NullWritable, Text> { @Override protected void reduce(Text eventTimeKey, Iterable<Text> timeGroupedRows, Context context) throws IOException, InterruptedException { int cnt = 1; final String eventTime = eventTimeKey.toString(); for (Text val : timeGroupedRows) { final String res = SEPERATOR.concat(getDate( Long.valueOf(eventTime)).concat( String.format(COUNT_FORMAT_DIGITS, cnt))); val.append(res.getBytes(), 0, res.length()); cnt++; context.write(NullWritable.get(), val); } } } public static String getDate(long time) { SimpleDateFormat utcSdf = new SimpleDateFormat("yyyyMMddhhmmss"); utcSdf.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles")); return utcSdf.format(new Date(time)); } public int run(String[] args) throws Exception { conf(args); return 0; } public static void main(String[] args) throws Exception { conf(args); } private static void conf(String[] args) throws IOException, InterruptedException, ClassNotFoundException { Configuration conf = new Configuration(); Job job = new Job(conf, "uniquekeygen"); job.setJarByClass(UniqueKeyGenerator.class); job.setOutputKeyClass(Text.class); job.setOutputValueClass(Text.class); job.setMapperClass(Map.class); job.setReducerClass(Reduce.class); job.setInputFormatClass(TextInputFormat.class); job.setOutputFormatClass(TextOutputFormat.class); // job.setNumReduceTasks(400); FileInputFormat.addInputPath(job, new Path(args[0])); FileOutputFormat.setOutputPath(job, new Path(args[1])); job.waitForCompletion(true); } } It is consistent for higher no of lines and the difference is as huge as 208969 records for an input of 20855982 lines. what might be the reason for reduced inputs to reducer?

  • How to return the date value from DatePickerDialog in Android?

    - by user1855222
    I am new to android . I ve created a Date picker in android using following guide .http://developer.android.com/guide/topics/ui/controls/pickers.html public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener { StringBuilder sb = new StringBuilder(); public static String date; @Override public Dialog onCreateDialog(Bundle savedInstanceState) { // Use the current date as the default date in the picker final Calendar c = Calendar.getInstance(); int year = c.get(Calendar.YEAR); int month = c.get(Calendar.MONTH); int day = c.get(Calendar.DAY_OF_MONTH); // Create a new instance of DatePickerDialog and return it return new DatePickerDialog(getActivity(), this, year, month, day); } public void onDateSet(DatePicker view, int year, int month, int day) { // Do something with the date chosen by the user sb.append(year); sb.append('-'); sb.append(month+1); sb.append('-'); sb.append(day); date = sb.toString(); System.out.println("The date is "+date); } I need to return this date value (date = sb.toString()) to my MainActivity . Since the onDateSet method is void what should I do ? Additional Information - DatePickerDialog Triggers at the MainActivity class ,But not with single button click . There are several processes happens in side a single button , Date picker will triggers only when certain condition is met . I do not want to display the date value either . Just want it returned for further processing. Appreciate any kind of guidance Changed onDataset method and justshow() public void onDateSet(DatePicker view, int year, int month, int day) { // Do something with the date chosen by the user sb.append(year); sb.append('-'); sb.append(month+1); sb.append('-'); sb.append(day); date = sb.toString(); MainActivity.newdate=sb.toString(); System.out.println("The date is "+MainActivity.newdate); } public void justShow(){ System.out.println("The date is "+MainActivity.newdate); } This is the relevant Part From Main(After making changes suggested in first reply ) DateToken mydate=new DateToken(); String test=dayvals.get(0); DialogFragment df=new DatePickerFragment(); if(test.equalsIgnoreCase("day")){ df.show(getSupportFragmentManager(), "DatePik"); } System.out.println("Date is on Main"+newdate); DatePickerFragment dpf=new DatePickerFragment(); dpf.justShow(); newdate is the static String , but still outputs null. In both MainActivity and justShow methods . But in onDataSet method date outputs correctly

  • JSON.Net: deserializing polymorphic types without specifying the assembly

    - by Frank Schwieterman
    I see that using JSON.Net, I can decode polymorphic objects if a $type attribute specifies the specific type of the JSON object. In all the examples I've seen, $type includes the namespace. Is it possible to make this work including just a simple typename without the assembly? I'd be happy to specify a default assembly to the JsonSerializer if thats possible I am able to deserialize the JSON using: public class SingleAssemblyJsonTypeBinder : SerializationBinder { private readonly Assembly _assembly; private Dictionary _typesBySimpleName = new Dictionary(StringComparer.OrdinalIgnoreCase); private Dictionary _simpleNameByType = new Dictionary(); public SingleAssemblyJsonTypeBinder(Assembly assembly) { _assembly = assembly; _typesBySimpleName = new Dictionary<string, Type>(); foreach (var type in _assembly.GetTypes().Where(t => t.IsPublic)) { if (_typesBySimpleName.ContainsKey(type.Name)) throw new InvalidOperationException("Cannot user PolymorphicBinder on a namespace where multiple public types have same name."); _typesBySimpleName[type.Name] = type; _simpleNameByType[type] = type.Name; } } public override Type BindToType(string assemblyName, string typeName) { Type result; if (_typesBySimpleName.TryGetValue(typeName.Trim(), out result)) return result; return null; } public override void BindToName(Type serializedType, out string assemblyName, out string typeName) { string name; if (_simpleNameByType.TryGetValue(serializedType, out name)) { typeName = name; assemblyName = null;// _assembly.FullName; } else { typeName = null; assemblyName = null; } } } ... public static JsonSerializerSettings GetJsonSerializationSettings() { var settings = new JsonSerializerSettings(); settings.Binder = new SingleAssemblyJsonTypeBinder(typeof(MvcApplication).Assembly); settings.TypeNameHandling = TypeNameHandling.Objects; return settings; } .... var serializer = JsonSerializer.Create(settings); I haven't been able to make this work with MVC though, I'm configuring json deserialization per the code below in Application_Start, and the object is deserialized, but using the base type one. GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Binder = new SingleAssemblyJsonTypeBinder(this.GetType().Assembly); GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.TypeNameHandling = TypeNameHandling.All; GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.TypeNameAssemblyFormat = FormatterAssemblyStyle.Simple;

  • I have to select the checkbox two times to check/uncheck in jTable

    - by 117526709403775781607
    I have a jTable code i intend to use, but the problem with it is that when i click on the checkbox once it doesn't select/deselect it, instead i have to click twice. But if i select any other cell in the row except the one containing the checkbox the purpose is solved. HERE IS MY CODE : public class TableSelectionTest extends JFrame implements ListSelectionListener { private final int COLUMN_COUNT = 5; private TblModel model; public TableSelectionTest() { initialize(); setDefaultCloseOperation(EXIT_ON_CLOSE); pack(); } private void initialize() { List data = new ArrayList(); for (int i = 0; i < 10; i++) { Object record[] = new Object[COLUMN_COUNT]; record[0] = Boolean.FALSE; for (int j = 1; j < COLUMN_COUNT; j++) { record[j] = new Integer(j); } data.add(record); } model = new TblModel(data); JTable table = new JTable(model); table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION); table.getSelectionModel().addListSelectionListener (this); JScrollPane scroll = new JScrollPane(table); getContentPane().add(scroll, BorderLayout.CENTER); } public static void main(String[] args) { TableSelectionTest f = new TableSelectionTest(); f.show(); } class TblModel extends AbstractTableModel { private List data; public TblModel(List data) { this.data = data; } public int getColumnCount() { return COLUMN_COUNT; } public int getRowCount() { return data == null ? 0 : data.size(); } public void setValueAt(Object value, int rowIndex, int columnIndex) { getRecord(rowIndex)[columnIndex] = value; super.fireTableCellUpdated(rowIndex, columnIndex); } public Object getValueAt(int rowIndex, int columnIndex) { return getRecord(rowIndex)[columnIndex]; } public boolean isCellEditable(int rowIndex, int columnIndex) { if(columnIndex == 0) return true; else return false; } public Class getColumnClass(int columnIndex) { if (data == null || data.size() == 0) { return Object.class; } Object o = getValueAt(0, columnIndex); return o == null ? Object.class : o.getClass(); } private Object[] getRecord(int rowIndex) { return (Object[]) data.get(rowIndex); } } public void valueChanged(ListSelectionEvent e) { if (!e.getValueIsAdjusting()) { ListSelectionModel lsm = (ListSelectionModel) e.getSource(); int index = lsm.getMinSelectionIndex(); if(model.getRecord(index)[0] == Boolean.FALSE) model.setValueAt(Boolean.TRUE, index, 0); else if(model.getRecord(index)[0] == Boolean.TRUE) model.setValueAt(Boolean.FALSE, index, 0); } } } Please reply soon as it is bugging me a lot Thank you in advance :)

  • Java program has errors, 80 lines of code

    - by user2961687
    I have a problem with a program. It contains a lot of errors in Eclipse. Sorry for my english and thank you in advance. Here is the task: I. Declare a class that contains private fields Jam: String taste, double weight Create constructors containing variables as parameters: (String taste, double weight), (double weight), (String taste). Parameters constructors should initialize class fields. In case the constructor does not provide the necessary parameter, it must be assumed that the field taste must have the value "No Name" and weight - 100.0. Introduce the use of all constructors creating objects that represent three kinds of jams. Note: it must be assumed that the only constructor with two parameters can be assigned to fields of the class. Declare a class Jar that contains the field Jam jam, a dedicated constructor initiating all declared fields and methods: open close isItOpen Next, create an object of class Jar and fill it with the selected type of jam, operations repeat for all the kinds of jams. This is my code this far: public class App { public static void main(String[] args) { Jam strawberry = new Jam("strawberry", 20.45); Jam raspberry = new Jam(40.50); Jam peach = new Jam("peach"); Jar jar_1 = new Jar(); Jar jar_2 = new Jar(); Jar jar_3 = new Jar(); jar_1.open(); jar_1.fillIn(strawberry); jar_2.fillIn(peach); jar_3.fillIn(raspberry); } } class Jam { String taste; double weight; public Jam(String taste, double weight) { this.taste = taste; this.weight = weight; } public Jam(double weight) { this.taste = "No name"; this.weight = weight; } public Jam(String taste) { this.taste = taste; this.weight = 100.0; } } class Jar { public Jam Jam = new Jam(); private String state_jar; public Jar() { Jam.weight = 0; Jam.taste = ""; state_jar = "closed"; } public static String open() { state_jar = open; return state_jar; } public static String close() { state_jar = "closed"; return state_jar; } public static boolean isItOpen() { return state_jar; } public void fillIn(Jam jam) { if (isItOpen == false) open(); this.Jam.weight = jam.weight; this.Jam.taste = jam.taste; this.Jam.close(); } }

  • How do you reach a "flow" state while programming?

    - by acrosman
    I'm not talking about program flow, but as in the state of working called flow, the state where you can get great work done the most effectively. I find that my current work environment while good in many ways does not allow me to get into a good state of mind for writing code most of the time (my job includes many other functions). If it's critical to get something done I'll often put on head-phones with classical music and try to drown out the office noise around me (and discourage co-workings from asking me questions). I am best able to get work done late in the evening when the house is quite and I've been thinking about the project for most of the day. What tricks have you found when working in less then perfect office environments?

  • SQL/Schema comparison and upgrade

    - by Workshop Alex
    I have a simple situation. A large organisation is using several different versions of some (desktop) application and each version has it's own database structure. There are about 200 offices and each office will have it's own version, which can be one of 7 different ones. The company wants to upgrade all applications to the latest versions, which will be version 8. The problem is that they don't have a separate database for each version. Nor do they have a separate database for each office. They have one single database which is handled by a dedicated server, thus keeping things like management and backups easier. Every office has it's own database schema and within the schema there's the whole database structure for their specific application version. As a result, I'm dealing with 200 different schema's which need to be upgraded, each with 7 possible versions. Fortunately, every schema knows the proper version so checking the version isn't difficult. But my problem is that I need to create upgrade scripts which can upgrade from version 1 to version 2 to version 3 to etc... Basically, all schema's need to be bumped up one version until they're all version 8. Writing the code that will do this is no problem. the challenge is how to create the upgrade script from one version to the other? Preferably with some automated tool. I've examined RedGate's SQL Compare and Altova's DatabaseSpy but they're not practical. Altova is way too slow. RedGate requires too much processing afterwards, since the generated SQL Script still has a few errors and it refers to the schema name. Furthermore, the code needs to become part of a stored procedure and the code generated by RedGate doesn't really fit inside a single procedure. (Plus, it's doing too much transaction-handling, while I need everything within a single transaction. I have been considering using another SQL Comparison tool but it seems to me that my case is just too different from what standard tools can deliver. So I'm going to write my own comparison tool. To do this, I'll be using ADOX with Delphi to read the catalogues for every schema version in the database, then use this to write the SQL Statements that will need to upgrade these schema's to their next version. (Comparing 1 with 2, 2 with 3, 3 with 4, etc.) I'm not unfamiliar with generating SQL-Script-Generators so I don't expect too many problems. And I'll only be upgrading the table structures, not any of the other database objects. So, does anyone have some good tips and tricks to apply when doing this kind of comparisons? Things to be aware of? Practical tips to increase speed?

  • How should Application.Run() be called for the main presenter a MVP WinForms app?

    - by Mr Roys
    I'm learning to apply MVP to a simple WinForms app (only one form) in C# and encountered an issue while creating the main presenter in static void Main(). Is it a good idea to expose a View from the Presenter in order to supply it as a parameter to Application.Run()? Currently, I've implemented an approach which allows me to not expose the View as a property of Presenter: static void Main() { IView view = new View(); Model model = new Model(); Presenter presenter = new Presenter(view, model); presenter.Start(); Application.Run(); } The Start and Stop methods in Presenter: public void Start() { view.Start(); } public void Stop() { view.Stop(); } The Start and Stop methods in View (a Windows Form): public void Start() { this.Show(); } public void Stop() { // only way to close a message loop called // via Application.Run(); without a Form parameter Application.Exit(); } The Application.Exit() call seems like an inelegant way to close the Form (and the application). The other alternative would be to expose the View as a public property of the Presenter in order to call Application.Run() with a Form parameter. static void Main() { IView view = new View(); Model model = new Model(); Presenter presenter = new Presenter(view, model); Application.Run(presenter.View); } The Start and Stop methods in Presenter remain the same. An additional property is added to return the View as a Form: public void Start() { view.Start(); } public void Stop() { view.Stop(); } // New property to return view as a Form for Application.Run(Form form); public System.Windows.Form View { get { return view as Form(); } } The Start and Stop methods in View (a Windows Form) would then be written as below: public void Start() { this.Show(); } public void Stop() { this.Close(); } Could anyone suggest which is the better approach and why? Or there even better ways to resolve this issue?

  • Beginning VSTO development

    - by idazuwaika
    Hi, I'm quite confused with what are the necessary tools for VSTO develpment. Specifically I want to manipulate Excel 2003/2007 documents programmatically. I did quite a lot of VBA before, if you want to relate any answer to that. Few questions I have about VSTO: Can I use Visual Studio 2008 Express Edition C#/C++ for this? Do I need to have .NET framework installed? Does the resulting VSTO program need to have a copy of Office installed in the same system to run? Direct links to the relevant tools/plugins/IDE will be appreciated. Note: I'm totally new to VSTO and .NET but an Office power user. Have experience with COM programming. Thanks.

  • WPF windows locked when calling webservice. Even when run asynchronously

    - by SumGuy
    Hi there. I'm having a big problem when calling a web service from my WPF application. The application/window locks until the process has completed. I've attempted to run this asynchronously but the problem still persists. Currently, the web service call I'm making can last 45-60 seconds. It runs a process on the server to fetch a big chunk of data. As it take a little while I wanted to have a progress bar moving indeterminately for the user to see that the application hasn't stalled or anything (you know how impatatient they get). So: private void btnSelect_Click(object sender, RoutedEventArgs e) { wDrawingList = new WindowDrawingList(systemManager); AsyncMethodHandler caller = default(AsyncMethodHandler); caller = new AsyncMethodHandler(setupDrawingList); // open new thread with callback method caller.BeginInvoke((Guid)((Button)sender).Tag, MyAsyncCallback, null); } Click a button and the app will create the form that the async stuff will be posted to and set up the async stuff calling the async method. public bool setupDrawingList(Guid ID) { if (systemManager.set(ID)) { wDrawingList.Dispatcher.Invoke(DispatcherPriority.Background, new Action(() => { wDrawingList.ShowForm(); Hide(); })); return true; } return false; } This is the async method. The showForm method contains the calls to setup the new form including the monster web service call public void MyAsyncCallback(IAsyncResult ar) { // Because you passed your original delegate in the asyncState parameter of the Begin call, you can get it back here to complete the call. MethodDelegate dlgt = (MethodDelegate)ar.AsyncState; // Complete the call. bool output = dlgt.EndInvoke(ar); try { // Retrieve the delegate. AsyncResult result = (AsyncResult)ar; AsyncMethodHandler caller = (AsyncMethodHandler)result.AsyncDelegate; // Because this method is running from secondary thread it can never access ui objects because they are created // on the primary thread. // Call EndInvoke to retrieve the results. bool returnValue = caller.EndInvoke(ar); // Still on secondary thread, must update ui on primary thread UpdateUI(returnValue == true ? "Success" : "Failed"); } catch (Exception ex) { string exMessage = null; exMessage = "Error: " + ex.Message; UpdateUI(exMessage); } } public void UpdateUI(string outputValue) { // Get back to primary thread to update ui UpdateUIHandler uiHandler = new UpdateUIHandler(UpdateUIIndicators); string results = outputValue; // Run new thread off Dispatched (primary thread) this.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, uiHandler, results); } public void UpdateUIIndicators(string outputValue) { // update user interface controls from primary UI thread sbi3.Content = "Processing Completed."; } Any help or theories are appreciated. I'm at a loss. Thanks in advance

  • C# Program gets stuck

  • Serialize problem with cookie

    - by cagin
    Hi there, I want use cookie in my web project. I must serialize my classes. Although my code can seralize an int or string value, it cant seralize my classes. This is my seralize and cookie code : public static bool f_SetCookie(string _sCookieName, object _oCookieValue, DateTime _dtimeExpirationDate) { bool retval = true; try { if (HttpContext.Current.Request[_sCookieName] != null) { HttpContext.Current.Request.Cookies.Remove(_sCookieName); } BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); bf.Serialize(ms, _oCookieValue); byte[] bArr = ms.ToArray(); MemoryStream objStream = new MemoryStream(); DeflateStream objZS = new DeflateStream(objStream, CompressionMode.Compress); objZS.Write(bArr, 0, bArr.Length); objZS.Flush(); objZS.Close(); byte[] bytes = objStream.ToArray(); string sCookieVal = Convert.ToBase64String(bytes); HttpCookie cook = new HttpCookie(_sCookieName); cook.Value = sCookieVal; cook.Expires = _dtimeExpirationDate; HttpContext.Current.Response.Cookies.Add(cook); } catch { retval = false; } return retval; } And here is one of my classes: [Serializable] public class Tahlil { #region Props & Fields public string M_KlinikKodu{ get; set; } public DateTime M_AlinmaTarihi { get; set; } private List<Test> m_Tesler; public List<Test> M_Tesler { get { return m_Tesler; } set { m_Tesler = value; } } #endregion public Tahlil() {} Tahlil(DataRow _rwTahlil){} } I m calling my Set Cookie method: Tahlil t = new Tahlil(); t.M_AlinmaTarihi = DateTime.Now; t.M_KlinikKodu = "2"; t.M_Tesler = new List<Test>(); f_SetCookie("Tahlil", t, DateTime.Now.AddDays(1)); I cant see cookie in Cookie folder and Temporary Internet Files but if i will call method like that: f_SetCookie("TRY", 5, DateTime.Now.AddDays(1)); I can see cookie. What is the problem? I dont understand. Thank you for your helps.

    - by Pierre
    I need to determine the location of (mobiles) users within the enterprise buildings & floors. They are all using Microsoft Exchange & Office Communicator. If I have access to the IP address, I can know the location. Is there a way to retrieve the last IP address of the user by using Microsoft Exchange or Office Communication Server API ? If yes how ? Thanks a lot in advance.

  • Changing Data in ListView

    - by legr3c
    Hi In my app I use a ListView to display data from the database. The data changes sometimes, for example when the user applies new filters or changes the sorting method. I use AsyncTask to get the databsase cursor that points to the new data set because sometimes data needs to be loaded from the net which can take some time. What I do now looks something like this: private class updateTask extends AsyncTask<Void, Void, Void> { /* * runs on the UI thread before doInBackground */ @Override protected void onPreExecute(){ // prepare some stuff... } /* * runs in a separate thread * used for time-consuming loading operation */ @Override protected Void doInBackground() { //get new database cursor mCursor = mDbAdapter.getCursor(); return null; } /* * runs on the UI thread after doInBackground */ @Override protected void onPostExecute(Void result){ if(mCursor!=null){ MyActivity.this.startManagingCursor(mCursor); mCursorAdapter = new MyCustomCursorAdapter(MyActivity.this, mCursor); mListView.setAdapter(mCursorAdapter); } } } This works so far but I realize that creating a new CursorAdapter and calling setAdapter on my ListView each time isn't the correct way to do it. Also, after setAdapter the scroll position of the list is set back to the top. I found this post which describes how to do it properly. So now I want to do something like this: onCreate(){ // ... // create the CursorAdapter using null as the initial cursor MyCustomCursorAdapter cursorAdapter = new MyCustomCursorAdapter(this, null); mListView.setAdapter(cursorAdapter); // ... } private class updateTask extends AsyncTask<Void, Void, Void> { /* * runs on the UI thread before doInBackground */ @Override protected void onPreExecute(){ // prepare some stuff... } /* * runs in a separate thread * used for time-consuming loading operation */ @Override protected Void doInBackground() { //get new database cursor mCursor = mDbAdapter.getCursor(); return null; } /* * runs on the UI thread after doInBackground */ @Override protected void onPostExecute(Void result){ // this returns null! MyCustomCursorAdapter cursorAdapter = (MyCustomCursorAdapter)mListView.getAdapter(); Cursor oldCursor = cursorAdapter.getCursor(); if(oldCursor!=null){ MyActivity.this.stopManagingCursor(oldCursor); oldCursor.close(); } if(mCursor!=null){ MyActivity.this.startManagingCursor(mCursor); cursorAdapter.changeCursor(mCursor); } } } This however doesn't work for me because (MyCustomCursorAdapter)mListView.getAdapter(); always returns null. Why does this happen? What am I doing wrong? Edit: Some additional information: my adapter implements SectionIndexer. I don't really think that this has anything to do with my problem but it has caused me some troubles before so I thought I'd mention it.

  • GUI design techniques to enhance user experience

    - by aku
    What techniques do you know\use to create user-friendly GUI ? I can name following techniques that I find especially useful: Non-blocking notifications (floating dialogs like in Firefox3 or Vista's pop-up messages in tray area) Absence of "Save" button MS OneNote as an example. IM clients can save conversation history automatically Integrated search Search not only through help files but rather make UI elements searchable. Vista made a good step toward such GUI. Scout addin Microsoft Office was a really great idea. Context oriented UI (Ribbon bar in MS Office 2007) Do you implement something like listed techniques in your software? Edit: As Ryan P mentioned, one of the best way to create usable app is to put yourself in user's place. I totally agree with it, but what I want to see in this topic is specific techniques (like those I mentioned above) rather than general recommendations.

  • Java Best Practice for type resolution at runtime.

    - by Brian
    I'm trying to define a class (or set of classes which implement the same interface) that will behave as a loosely typed object (like JavaScript). They can hold any sort of data and operations on them depend on the underlying type. I have it working in three different ways but none seem ideal. These test versions only allow strings and integers and the only operation is add. Adding integers results in the sum of the integer values, adding strings concatenates the strings and adding an integer to a string converts the integer to a string and concatenates it with the string. The final version will have more types (Doubles, Arrays, JavaScript-like objects where new properties can be added dynamically) and more operations. Way 1: public interface DynObject1 { @Override public String toString(); public DynObject1 add(DynObject1 d); public DynObject1 addTo(DynInteger1 d); public DynObject1 addTo(DynString1 d); } public class DynInteger1 implements DynObject1 { private int value; public DynInteger1(int v) { value = v; } @Override public String toString() { return Integer.toString(value); } public DynObject1 add(DynObject1 d) { return d.addTo(this); } public DynObject1 addTo(DynInteger1 d) { return new DynInteger1(d.value + value); } public DynObject1 addTo(DynString1 d) { return new DynString1(d.toString()+Integer.toString(value)); } } ...and similar for DynString1 Way 2: public interface DynObject2 { @Override public String toString(); public DynObject2 add(DynObject2 d); } public class DynInteger2 implements DynObject2 { private int value; public DynInteger2(int v) { value = v; } @Override public String toString() { return Integer.toString(value); } public DynObject2 add(DynObject2 d) { Class c = d.getClass(); if(c==DynInteger2.class) { return new DynInteger2(value + ((DynInteger2)d).value); } else { return new DynString2(toString() + d.toString()); } } } ...and similar for DynString2 Way 3: public class DynObject3 { private enum ObjectType { Integer, String }; Object value; ObjectType type; public DynObject3(Integer v) { value = v; type = ObjectType.Integer; } public DynObject3(String v) { value = v; type = ObjectType.String; } @Override public String toString() { return value.toString(); } public DynObject3 add(DynObject3 d) { if(type==ObjectType.Integer && d.type==ObjectType.Integer) { return new DynObject3(Integer.valueOf(((Integer)value).intValue()+((Integer)value).intValue())); } else { return new DynObject3(value.toString()+d.value.toString()); } } } With the if-else logic I could use value.getClass()==Integer.class instead of storing the type but with more types I'd change this to use a switch statement and Java doesn't allow switch to use Classes. Anyway... My question is what is the best way to go about something thike this?
