  • BroadcastReceiver not reading stored value from SharedPreferences

    - by bobby123
    In my app I have a broadcast receiver that turns on GPS upon receiving a set string of text. In the onLocationChanged method, I want to pass the GPS data and a value from my shared preferences to a thread in a string. I have the thread writing to log and can see all the GPS values in the string but the last value from my shared preferences is just showing up as 'prefPhoneNum' which I initialised the string to at the beginning of the receiver class. I have the same code to read the prefPhoneNum from shared preferences in the main class and it works there, can anyone see what I might be doing wrong? public class SmsReceiver extends BroadcastReceiver implements LocationListener { LocationManager lm; LocationListener loc; public SharedPreferences sharedpreferences; public static final String US = "usersettings"; public String prefPhoneNum = "prefPhoneNum"; @Override public void onReceive(Context context, Intent intent) { sharedpreferences = context.getSharedPreferences(US, Context.MODE_PRIVATE); prefPhoneNum = sharedpreferences.getString("prefPhoneNum" , ""); lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); loc = new SmsReceiver(); //---get the SMS message passed in--- Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String str = ""; if (bundle != null) { //---retrieve the SMS message received--- Object[] pdus = (Object[]) bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; for (int i=0; i<msgs.length; i++) { msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]); str += msgs[i].getMessageBody().toString() + "\n"; } Toast.makeText(context, str, Toast.LENGTH_SHORT).show(); //Display SMS if ((msgs[0].getMessageBody().toString().equals("Enable")) || (msgs[0].getMessageBody().toString().equals("enable"))) { enableGPS(); } else { /* Do Nothing*/ } } } public void enableGPS() { //new CountDownTimer(10000, 1000) { //10 seconds new CountDownTimer(300000, 1000) { //300 secs = 5 mins public void onTick(long millisUntilFinished) { lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, loc); } public void onFinish() { lm.removeUpdates(loc); } }.start(); } @Override public void onLocationChanged(Location location) { String s = ""; s += location.getLatitude() + "\n"; s += location.getLongitude() + "\n"; s += location.getAltitude() + "\n"; s += location.getAccuracy() + "\n" + prefPhoneNum; Thread cThread = new Thread(new SocketsClient(s)); cThread.start(); } @Override public void onProviderDisabled(String provider) { } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } } Here is the logcat for when the application shuts - D/LocationManager( 3912): requestLocationUpdates: provider = gps, listener = accel.working.TrackGPS@4628bce0 D/GpsLocationProvider( 96): setMinTime 0 D/GpsLocationProvider( 96): startNavigating D/GpsLocationProvider( 96): TTFF: 3227 D/AndroidRuntime( 3912): Shutting down VM W/dalvikvm( 3912): threadid=1: thread exiting with uncaught exception (group=0x400259f8) E/AndroidRuntime( 3912): FATAL EXCEPTION: main E/AndroidRuntime( 3912): java.lang.NullPointerException E/AndroidRuntime( 3912): at android.content.ContextWrapper.getSharedPreferences(ContextWrapper.java:146) E/AndroidRuntime( 3912): at accel.working.TrackGPS.onLocationChanged(TrackGPS.java:63) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport._handleMessage(LocationManager.java:191) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport.access$000(LocationManager.java:124) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport$1.handleMessage(LocationManager.java:140) E/AndroidRuntime( 3912): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 3912): at android.os.Looper.loop(Looper.java:144) E/AndroidRuntime( 3912): at android.app.ActivityThread.main(ActivityThread.java:4937) E/AndroidRuntime( 3912): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 3912): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 3912): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) E/AndroidRuntime( 3912): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) E/AndroidRuntime( 3912): at dalvik.system.NativeStart.main(Native Method)

  • Error Handling without Exceptions

    - by James
    While searching SO for approaches to error handling related to business rule validation , all I encounter are examples of structured exception handling. MSDN and many other reputable development resources are very clear that exceptions are not to be used to handle routine error cases. They are only to be used for exceptional circumstances and unexpected errors that may occur from improper use by the programmer (but not the user.) In many cases, user errors such as fields that are left blank are common, and things which our program should expect, and therefore are not exceptional and not candidates for use of exceptions. QUOTE: Remember that the use of the term exception in programming has to do with the thinking that an exception should represent an exceptional condition. Exceptional conditions, by their very nature, do not normally occur; so your code should not throw exceptions as part of its everyday operations. Do not throw exceptions to signal commonly occurring events. Consider using alternate methods to communicate to a caller the occurrence of those events and leave the exception throwing for when something truly out of the ordinary happens. For example, proper use: private void DoSomething(string requiredParameter) { if (requiredParameter == null) throw new ArgumentExpcetion("requiredParameter cannot be null"); // Remainder of method body... } Improper use: // Renames item to a name supplied by the user. Name must begin with an "F". public void RenameItem(string newName) { // Items must have names that begin with "F" if (!newName.StartsWith("F")) throw new RenameException("New name must begin with /"F/""); // Remainder of method body... } In the above case, according to best practices, it would have been better to pass the error up to the UI without involving/requiring .NET's exception handling mechanisms. Using the same example above, suppose one were to need to enforce a set of naming rules against items. What approach would be best? Having the method return a enumerated result? RenameResult.Success, RenameResult.TooShort, RenameResult.TooLong, RenameResult.InvalidCharacters, etc. Using an event in a controller class to report to the UI class? The UI calls the controller's RenameItem method, and then handles an AfterRename event that the controller raises and that has rename status as part of the event args? The controlling class directly references and calls a method from the UI class that handles the error, e.g. ReportError(string text). Something else... ? Essentially, I want to know how to perform complex validation in classes that may not be the Form class itself, and pass the errors back to the Form class for display -- but I do not want to involve exception handling where it should not be used (even though it seems much easier!) Based on responses to the question, I feel that I'll have to state the problem in terms that are more concrete: UI = User Interface, BLL = Business Logic Layer (in this case, just a different class) User enters value within UI. UI reports value to BLL. BLL performs routine validation of the value. BLL discovers rule violation. BLL returns rule violation to UI. UI recieves return from BLL and reports error to user. Since it is routine for a user to enter invalid values, exceptions should not be used. What is the right way to do this without exceptions?

  • Passing Variables between views / view controllers

    - by Dan
    Hi I'm new to ObjectiveC / IPhoneSDK and I'm informally trying to study it on my own. What I'm basically trying to do is from one view there are 12 zodiac signs. When a user clicks one, it proceeds to the second view (with animation) and loads the name of the zodiac sign it clicked in a UILabel, that's it. Here are my codes: Lovescopes = 1st page Horoscopes = 2nd page Lovescopes4AppDelegate.h #import <UIKit/UIKit.h> #import "HoroscopesViewController.h" #import "Lovescopes4AppDelegate.h" @class Lovescopes4ViewController; @interface Lovescopes4AppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; Lovescopes4ViewController *viewController; HoroscopesViewController *horoscopesViewController; } -(void)loadHoroscope; -(void)loadMainPage; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet Lovescopes4ViewController *viewController; @property (nonatomic, retain) HoroscopesViewController *horoscopesViewController; @end Lovescopes4AppDelegate.m #import "Lovescopes4AppDelegate.h" #import "Lovescopes4ViewController.h" @implementation Lovescopes4AppDelegate @synthesize window; @synthesize viewController; @synthesize horoscopesViewController; -(void)loadHoroscope { HoroscopesViewController *aHoroscopeViewController = [[HoroscopesViewController alloc] initWithNibName:@"HoroscopesViewController" bundle:nil]; [self setHoroscopesViewController:aHoroscopeViewController]; [aHoroscopeViewController release]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:window cache:YES]; [viewController.view removeFromSuperview]; [self.window addSubview:[horoscopesViewController view]]; [UIView commitAnimations]; } -(void)loadMainPage { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:window cache:NO]; [horoscopesViewController.view removeFromSuperview]; [self.window addSubview:[viewController view]]; [UIView commitAnimations]; [horoscopesViewController release]; horoscopesViewController = nil; } - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end Lovescopes4ViewController.h #import <UIKit/UIKit.h> #import "HoroscopesViewController.h" @interface Lovescopes4ViewController : UIViewController { HoroscopesViewController *hvc; } -(IBAction)loadAries; @property (nonatomic, retain) HoroscopesViewController *hvc; @end Lovescope4ViewController.m #import "Lovescopes4ViewController.h" #import "Lovescopes4AppDelegate.h" @implementation Lovescopes4ViewController @synthesize hvc; -(IBAction)loadAries { NSString *selected =@"Aries"; [hvc loadZodiac:selected]; Lovescopes4AppDelegate *mainDelegate = (Lovescopes4AppDelegate *) [[UIApplication sharedApplication] delegate]; [mainDelegate loadHoroscope]; } HoroscopesViewController.h #import <UIKit/UIKit.h> @interface HoroscopesViewController : UIViewController { IBOutlet UILabel *zodiacLabel; } -(void)loadZodiac:(id)zodiacSign; -(IBAction)back; @property (nonatomic, retain) IBOutlet UILabel *zodiacLabel; @end HoroscopesViewController.m #import "HoroscopesViewController.h" #import "Lovescopes4AppDelegate.h" @implementation HoroscopesViewController @synthesize zodiacLabel; /* // The designated initializer.

  • C program runs in Cygwin but not Linux (Malloc)

    - by Shawn
    I have a heap allocation error that I cant spot in my code that is picked up on vanguard/gdb on Linux but runs perfectly on a Windows cygwin environment. I understand that Linux could be tighter with its heap allocation than Windows but I would really like to have a response that discovers the issue/possible fix. I'm also aware that I shouldn't typecast malloc in C but it's a force of habit and doesn't change my problem from happening. My program actually compiles without error on both Linux & Windows but when I run it in Linux I get a scary looking result: malloc.c:3074: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)-bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) = (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)-size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.

  • JAXB marshals XML differently to OutputStream vs. StringWriter

    - by Andy
    I apologize if this has been answered, but the search terms I have been using (i.e. JAXB @XmlAttribute condensed or JAXB XML marshal to String different results) aren't coming up with anything. I am using JAXB to un/marshal objects annotated with @XmlElement and @XmlAttribute annotations. I have a formatter class which provides two methods -- one wraps the marshal method and accepts the object to marshal and an OutputStream, the other just accepts the object and returns the XML output as a String. Unfortunately, these methods do not provide the same output for the same objects. When marshaling to a file, simple object fields internally marked with @XmlAttribute are printed as: <element value="VALUE"></element> while when marshaling to a String, they are: <element value="VALUE"/> I would prefer the second format for both cases, but I am curious as to how to control the difference, and would settle for them being the same regardless. I even created one static marshaller that both methods use to eliminate different instance values. The formatting code follows: /** Marker interface for classes which are listed in jaxb.index */ public interface Marshalable {} /** Local exception class */ public class XMLMarshalException extends BaseException {} /** Class which un/marshals objects to XML */ public class XmlFormatter { private static Marshaller marshaller = null; private static Unmarshaller unmarshaller = null; static { try { JAXBContext context = JAXBContext.newInstance("path.to.package"); marshaller = context.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8"); unmarshaller = context.createUnmarshaller(); } catch (JAXBException e) { throw new RuntimeException("There was a problem creating a JAXBContext object for formatting the object to XML."); } } public void marshal(Marshalable obj, OutputStream os) throws XMLMarshalException { try { marshaller.marshal(obj, os); } catch (JAXBException jaxbe) { throw new XMLMarshalException(jaxbe); } } public String marshalToString(Marshalable obj) throws XMLMarshalException { try { StringWriter sw = new StringWriter(); marshaller.marshal(obj, sw); } catch (JAXBException jaxbe) { throw new XMLMarshalException(jaxbe); } } } /** Example data */ @XmlType @XmlAccessorType(XmlAccessType.FIELD) public class Data { @XmlAttribute(name = value) private String internalString; } /** Example POJO */ @XmlType @XmlRootElement(namespace = "project/schema") @XmlAccessorType(XmlAccessType.FIELD) public class Container implements Marshalable { @XmlElement(required = false, nillable = true) private int number; @XmlElement(required = false, nillable = true) private String word; @XmlElement(required = false, nillable = true) private Data data; } The result of calling marshal(container, new FileOutputStream("output.xml")) and marshalToString(container) are as follows: Output to file <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:container xmlns:ns2="project/schema"> <number>1</number> <word>stackoverflow</word> <data value="This is internal"></data> </ns2:container> and Output to String <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:container xmlns:ns2="project/schema"> <number>1</number> <word>stackoverflow</word> <data value="This is internal"/> </ns2:container>

    This is my 1st C# project so I may be doing something obviously improper in the code below. I am using .NET, WinForms (I think), and this is a desktop application until I get the bugs out. UpdateGui() uses Invoke((MethodInvoker)delegate to update various GUI controls based on received serial data and sends a GetStatus() command out the serial port 4 times a second. Thread Read() reads the response from serial port whenever it arrives which should be near immediate. SerialPortFixer is a SerialPort IOException Workaround in C# I found at http://zachsaw.blogspot.com/2010/07/serialport-ioexception-workaround-in-c.html. After one or both threads die I'll see something like The thread 0x1288 has exited with code 0 (0x0). in the debug code output. Why do UpdateGui() and/or Read() eventually die? public partial class UpdateStatus : Form { private readonly byte[] Command = new byte[32]; private readonly byte[] Status = new byte[32]; readonly Thread readThread; private static readonly Mutex commandMutex = new Mutex(); private static readonly Mutex statusMutex = new Mutex(); ... public UpdateStatus() { InitializeComponent(); SerialPortFixer.Execute("COM2"); if (serialPort1.IsOpen) { serialPort1.Close(); } try { serialPort1.Open(); } catch (Exception e) { labelWarning.Text = LOST_COMMUNICATIONS + e; labelStatus.Text = LOST_COMMUNICATIONS + e; labelWarning.Visible = true; } readThread = new Thread(Read); readThread.Start(); new Timer(UpdateGui, null, 0, 250); } static void ProcessStatus(byte[] status) { Status.State = (State) status[4]; Status.Speed = status[6]; // MSB Status.Speed *= 256; Status.Speed += status[5]; var Speed = Status.Speed/GEAR_RATIO; Status.Speed = (int) Speed; ... } public void Read() { while (serialPort1 != null) { try { serialPort1.Read(Status, 0, 1); if (Status[0] != StartCharacter[0]) continue; serialPort1.Read(Status, 1, 1); if (Status[1] != StartCharacter[1]) continue; serialPort1.Read(Status, 2, 1); if (Status[2] != (int)Command.GetStatus) continue; serialPort1.Read(Status, 3, 1); ... statusMutex.WaitOne(); ProcessStatus(Status); Status.update = true; statusMutex.ReleaseMutex(); } catch (Exception e) { Console.WriteLine(@"ERROR! Read() " + e); } } } public void GetStatus() { const int parameterLength = 0; // For GetStatus statusMutex.WaitOne(); Status.update = false; statusMutex.ReleaseMutex(); commandMutex.WaitOne(); if (!SendCommand(Command.GetStatus, parameterLength)) { Console.WriteLine(@"ERROR! SendCommand(GetStatus)"); } commandMutex.ReleaseMutex(); } private void UpdateGui(object x) { try { Invoke((MethodInvoker)delegate { Text = DateTime.Now.ToLongTimeString(); statusMutex.WaitOne(); if (Status.update) { if (Status.Speed > progressBarSpeed.Maximum) { Status.Speed = progressBarSpeed.Maximum; } progressBarSpeed.Value = Status.Speed; labelSpeed.Text = Status.Speed + RPM; ... } else { labelWarning.Text = LOST_COMMUNICATIONS; labelStatus.Text = LOST_COMMUNICATIONS; labelWarning.Visible = true; } statusMutex.ReleaseMutex(); GetStatus(); }); } catch (Exception e) { Console.WriteLine(@"ERROR! UpdateGui() " + e); } } }

  • Foreign Key constraint when persisting a many-to-one class

    - by tieTYT
    I'm getting an error when trying to persist a many to one entity: Internal Exception: org.postgresql.util.PSQLException: ERROR: insert or update on table "concept" violates foreign key constraint "concept_concept_class_fk" Detail: Key (concept_class_id)=(Concept) is not present in table "concept_class".

And also, what's important is the sql that's being generated: INSERT INTO concept_class (id, oid, description, label) VALUES (?, ?, ?, ?) bind = [LOINC_TEST, 2.16.212.31.231.54, This is a meta data file for LOINC_TEST, loinc_test] INSERT INTO concept (concept_key, description, label, code, concept_class_id) VALUES (?, ?, ?, ?, ?) bind = [27, description_1, label_1, code_1, Concept] The reason this is failing is obvious: It's inserting the word Concept for the concept_class_id. It should be inserting the word LOINC_TEST. I can't figure out why it's using this word. I've used the debugger to look at the Concept and the ConceptClass instance and neither of them contain this word. I'm using eclipselink. Does anyone know why this is happening?

  • jqgrid retrieving empty rows using webapi (REST)

    - by polonskyg
    I'm using jqgrid in an ASPNET MVC4 project with WebApi (REST), Entity Framework 5 using Unit Of Work and Repository patterns. My problem is that I see the data flowing as json to the browser and I see three rows in the grid, but those rows are empty, and the data is not shown (three empty rows in the grid). This is method to get the data in the WebApi controller: public dynamic GetGridData(int rows, int page, string sidx, string sord) { var pageSize = rows; var index = sidx; var order = sord; var categories = Uow.Categories.GetAll().OrderBy(t => (string.IsNullOrEmpty(index) ? "Id" : index) + " " + (order ?? "desc")); var pageIndex = Convert.ToInt32(page) - 1; var totalRecords = categories.Count(); var totalPages = (int)Math.Ceiling((float) totalRecords / (float) pageSize); var categoriesPage = categories.Skip(pageIndex * pageSize).Take(pageSize).ToList(); return new { total = totalPages, page = page, records = totalRecords, rows = (from category in categoriesPage select new { id = category.Id.ToString(), cell = new string[] { category.Id.ToString(), category.Name, category.Description } }).ToArray() }; } This is the json received in the browser { "total": 1, "page": 1, "records": 3, "rows": [{ "id": "1", "cell": ["1", "Category 1", null] }, { "id": "3", "cell": ["3", "Category 3", "asAS"] }, { "id": "4", "cell": ["4", "Category 4", null] }] } This is the .js file with jqgrid jQuery("#ajaxGrid").jqGrid({ url: $("#ServiceUrl").val(), datatype: "json", jsonReader: { repeatitems: false, id: "Id" }, colNames: ['Id', 'Name', 'Description'], colModel: [ { name: 'id', editable: true, sortable: true, hidden: true, align: 'left' }, { name: 'name', editable: true, sortable: true, hidden: false, align: 'left' }, { name: 'description', editable: true, sortable: true, hidden: false, align: 'left' } ], mtype: 'GET', rowNum: 15, pager: '#ajaxGridPager', rowList: [10, 20, 50, 100], caption: 'List of Categories', imgpath: $("#ServiceImagesUrl").val(), altRows: true, shrinkToFit: true, viewrecords: true, autowidth: true, height: 'auto', error: function(x, e) { alert(x.readyState + " "+ x.status +" "+ e.msg); } }); function updateDialog(action) { return { url: $("#ServiceUrl").val(), closeAfterAdd: true, closeAfterEdit: true, afterShowForm: function (formId) { }, modal: true, onclickSubmit: function (params) { var list = $("#ajaxGrid"); var selectedRow = list.getGridParam("selrow"); params.url += "/" + list.getRowData(selectedRow).Id; params.mtype = action; }, width: "300", ajaxEditOptions: { contentType: "application/json" }, serializeEditData: function (data) { delete data.oper; return JSON.stringify(data); } }; } jQuery("#ajaxGrid").jqGrid( 'navGrid', '#ajaxGridPager', { add: true, edit: true, del: true, search: false, refresh: false }, updateDialog('PUT'), updateDialog('POST'), updateDialog('DELETE') ); BTW, If I want to return jqGridData instead the dynamic, How should I do it? Did is showing empty rows as well: public class jqGridData<T> where T : class { public int page { get; set; } public int records { get; set; } public IEnumerable<T> rows { get; set; } public decimal total { get; set; } } public jqGridData<Category> GetGridData(int rows, int page, string sidx, string sord) { var pageSize = rows; var index = sidx; var order = sord; var categories = Uow.Categories.GetAll().OrderBy(t => (string.IsNullOrEmpty(index) ? "Id" : index) + " " + (order ?? "desc")); var pageIndex = Convert.ToInt32(page) - 1; var totalRecords = categories.Count(); var totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize); var categoriesPage = categories.Skip(pageIndex * pageSize).Take(pageSize); return new jqGridData<Category> { page = page, records = totalRecords, total = totalPages, rows = categoriesPage }; }

  • CrossPage PostBack in series of web pages

    - by Vishnu Reddy
    I had a requirement to pass data between pages in my application. I have a Page A where user will input some data and on submit User will be redirected to Page B where again user will enter some more data and on submitting user will be show a confirmation in Page C after doing some calculations and data saving.

  • WCF REST Question, Binding, Configuration

    - by Ethan McGee
    I am working on a WCF rest interface using json. I have wrapped the service in a windows service to host the service but I am now having trouble getting the service to be callable. I am not sure exactly what is wrong. The basic idea is that I want to host the service on a remote server so I want the service mapped to port localhost:7600 so that it can be invoked by posting data to [server_ip]:7600. The problem is most likely in the configuration file, since I am new to WCF and Rest I wasn't really sure what to type for the configuration so sorry if it's a total mess. I removed several chunks of code and comments to make it a little easier to read. These functions should have no bearing on the service since they call only C# functions. WCF Service Code using System; using System.Collections.Generic; using System.Linq; using System.ServiceModel; using System.ServiceModel.Activation; using System.ServiceModel.Web; using System.Text; namespace PCMiler_Connect { public class ZIP_List_Container { public string[] ZIP_List { get; set; } public string Optimized { get; set; } public string Calc_Type { get; set; } public string Cross_International_Borders { get; set; } public string Use_Kilometers { get; set; } public string Hazard_Level { get; set; } public string OK_To_Change_Destination { get; set; } } [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] public class PCMiler_Webservice { [WebInvoke(Method = "POST", UriTemplate = "", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json), OperationContract] public List<string> Calculate_Distance(ZIP_List_Container container) { return new List<string>(){ distance.ToString(), time.ToString() }; } } } XML Config File <?xml version="1.0" encoding="utf-8"?> <configuration> <system.serviceModel> <services> <service name="PCMiler_Connect.PCMiler_Webservice"> <endpoint address="" behaviorConfiguration="jsonBehavior" binding="webHttpBinding" bindingConfiguration="" contract="PCMiler_Connect.PCMiler_Webservice" /> <host> <baseAddresses> <add baseAddress="http://localhost:7600/" /> </baseAddresses> </host> </service> </services> <behaviors> <endpointBehaviors> <behavior name="jsonBehavior"> <enableWebScript/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> </configuration> Service Wrapper using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.Linq; using System.ServiceProcess; using System.ServiceModel; using System.Text; using System.Threading; namespace PCMiler_WIN_Service { public partial class Service1 : ServiceBase { ServiceHost host; public Service1() { InitializeComponent(); } protected override void OnStart(string[] args) { host = new ServiceHost(typeof(PCMiler_Connect.PCMiler_Webservice)); Thread thread = new Thread(new ThreadStart(host.Open)); } protected override void OnStop() { if (host != null) { host.Close(); host = null; } } } }

  • Javascript tabs: call event onclick

    - by Joris
    I got some code I need to change. it is build by others, and not very neat... There is a javascript tabcontrol, containing 4 tabs, which contains gridviews. All the 4 gridviews are build during the load of the page, but I want them to load, when you activate the tabs (as it is possible to watch the side, while you don't need the specific gridviews to see) So, my question is: how to call an event (that loads the gridview) from an javascript tab? how the tabs are generated: (generated code, I know, horrible) var obj = 0; var oid = 0; var otb = 0; var myTabs = new Array(); var myTabitems = new Array(); var myTabitem = new Array(); var myTabContent = new Array(); var myLists = new Array(); function showTabContent(tab) { tb = tab.obj; id = tab.nr; if (myTabs[tb].oid != -1) { myTabs[tb].myTabContent[myTabs[tb].oid].style.display = 'none'; myTabs[tb].myTabitem[myTabs[tb].oid].className -= " active"; } myTabs[tb].myTabContent[id].style.display = 'block'; myTabs[tb].myTabitem[id].className += " active"; myTabs[tb].oid = id; } function boTabs() { var myBlocks = new Array(); myBlocks = document.getElementsByTagName("div"); var stopit = myBlocks.length; for (var g = 0; g < stopit; g++) { if (myBlocks[g].className == "tabs") { myTabs.push(myBlocks[g]); } } var stopit2 = myTabs.length; for (var i = 0; i < stopit2; i++) { myTabs[i].myLists = myTabs[i].getElementsByTagName("ul"); if (myTabs[i].myLists[0].className == "tabs") { myTabs[i].myTabitems = myTabs[i].myLists[0].getElementsByTagName("li"); } var stopit3 = myTabs[i].myTabitems.length; myTabs[i].obj = i; myTabs[i].myTabitem = new Array(); myTabs[i].myTabContent = new Array(); for (var j = 0; j < stopit3; j++) { myTabs[i].myTabitem.push(myTabs[i].myTabitems[j]); myTabs[i].myTabitem[j].nr = j; myTabs[i].myTabitem[j].obj = i; myTabs[i].myTabitem[j].onclick = function() { showTabContent(this); }; } var myTabDivs = myTabs[i].getElementsByTagName("div"); for (var j = 0; j < myTabDivs.length; j++) { if (myTabDivs[j].className == "tabcontent") { myTabs[i].myTabContent.push(myTabDivs[j]); } } myTabs[i].myTabitem[0].className += " active"; myTabs[i].myTabContent[0].style.display = 'block'; myTabs[i].oid = 0; myTabDivs = null; } myBlocks = null; } onload = boTabs;

I also tried following this tutorial: link text But it doesn't work for me :( Here is my code: TiMTabBar.h @protocol TiMTabBarDelegate; @interface TiMTabBar : UIView { id<TiMTabBarDelegate> __delegate; ... int selectedItem; ... } //- (id)init; - (id)initWithDelegate:(id)aDelegate; - (void)setSelectedIndex:(int)item; .. @property (nonatomic) int selectedItem; @property(assign) id <TiMTabBarDelegate> __delegate; .. ... @end @protocol TiMTabBarDelegate<NSObject> //@optional - (void)tabBar:(TiMTabBar *)_tabBar didSelectIndex:(int)index; @end TiMTabBar.m: #import "TiMTabBar.h" ... @interface NSObject (TiMTabBarDelegate) - (void)tabBar:(TiMTabBar *)_tabBar didSelectIndex:(int)index; @end @implementation TiMTabBar @synthesize selectedItem; @synthesize __delegate; ... /* - (id)init { ... return self; } */ - (id)initWithDelegate:(id)aDelegate; { //[super init]; __delegate = aDelegate; return self; } - (void)awakeFromNib { //[self init]; //[self initWithDelegate:self]; ... } - (void)setSelectedIndex:(int)item { selectedItem = item; if (self.__delegate != NULL && [self.__delegate respondsToSelector:@selector(tabBar:didSelectIndex:)]) { [__delegate tabBar:self didSelectIndex:selectedItem]; } ... if (item == 0) { ... } else if (item == 1) { ... } else if (item == 2) { ... } else if (item == 3) { ... } else if (item == 4) { ... } else { ... } } /* - (void)tabBar:(TiMTabBar *)_tabBar didSelectIndex:(int)index; { //[delegate tabBar:self didSelectIndex:index]; //if (self.delegate != NULL && [self.delegate respondsToSelector:@selector(tabBar:didSelectIndex:)]) { //[delegate tabBar:self didSelectIndex:selectedItem]; //} NSLog(@"tabBarDelegate: %d",index); } */ @end The delegate only works works inside itself and not in any other files like: @interface XXXController : UIViewController <TiMTabBarDelegate> { ... ... IBOutlet TiMTabBar *tabBar; ... } ... @end XXXController.m: #import "XXXController.h" #import <QuartzCore/QuartzCore.h> @implementation XXXController - (void)viewDidLoad { [super viewDidLoad]; [self becomeFirstResponder]; ... tabBar = [[TiMTabBar alloc] initWithDelegate:self]; //tabBar.__delegate = self; ... } #pragma mark TiMTabBar Stuff - (void)tabBar:(TiMTabBar *)_tabBar didSelectIndex:(int)index; { NSLog(@"Controller/tabBarDelegate: %d",index); } @end None of this seems to work in XXXController. Anyone know how to make this work?

  • how to solve unhandled exception error when using visual C++ 2008?

    Hi, Could someone please help me to solve unhandled exception error when using visual C++ 2008? the error is displayed as follow: Unhandled exception at 0x00411690 in time.exe: 0xC0000005: Access violation reading location 0x00000008 Actually when I used visual c++ 6 in the past, there weren't any error and the program was running fine.

  • C# Accessing controls from an outside class without "public"

    - by Kurt W
    I know this has been asked before but I believe my situation is a bit different -- or I don't understand the answers given. I have spent about 4 hours working on this solidly and finally realized, I just don't know what to do. I have 2 Forms (Form1, Settings) and a class I created called Themes. I have get/set properties that currently work but are all within Form1 and I would like to move as much code related to themeing as I can OUTSIDE of Form1 and into Themes.cs. Changing Theme: To change the theme, the user opens up the Settings form and selects a theme from the dropdown menu and presses the 'Set' button -- this all works, but now I want to move it into my own class and I can't get the code to compile. Here is example code that works before moving -- note that this is only 2 different controls I want to modify but there are about 30 total. I am abridging the code: Form 1: public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void btnSettings_Click(object sender, EventArgs e) { Settings frm = new Settings(this); frm.Show(); } private Color txtRSSURLBGProperty; private Color txtRSSURLFGProperty; public Color TxtRSSURLBGProperty { get { return txtRSSURLBGProperty; } set { txtRSSURL.BackColor = value; } } public Color TxtRSSURLFGProperty { get { return txtRSSURLFGProperty; } set { txtRSSURL.ForeColor = value; } } Settings Form: public partial class Settings : Form { public Settings() { InitializeComponent(); } private Form1 rssReaderMain = null; public Settings(Form requestingForm) { rssReaderMain = requestingForm as Form1; InitializeComponent(); } private void button2_Click(object sender, EventArgs args) { // Appearence settings for DEFAULT THEME if (cbThemeSelect.SelectedIndex == 1) { this.rssReaderMain.TxtRSSURLBGProperty = Color.DarkSeaGreen; this.rssReaderMain.TxtRSSURLFGProperty = Color.White; [......about 25 more of these....] } The theme class is currently empty. Again, the goal is to move as much code into the themes class (specifically the get/set statements if at all possible!) and hopefully just use a method similar to this within the Settings form once the proper drowndown item is selected: SetTheme(Default); I hope someone can help, and I hope I explained it right! I have been racking my brain and I need to have this done fairly soon! Much thanks in advance as I'm sure everyone says. I have teamviewer or logmein if someone wants to remote in -- that is just as easy. I can also send my project as a zip if needed. Thanks so much, Kurt Modified code for review: Form1 form: public partial class Form1 : ThemeableForm { public Form1() { InitializeComponent(); } ThemeableForm form: internal abstract class ThemeableForm : Form { private Color rssLabelBGProperty; private Color rssLabelFGProperty; public Color RssLabelBGProperty { get { return rssLabelBGProperty; } set { lRSS.BackColor = value; } } public Color RssLabelFGProperty { get { return rssLabelFGProperty; } set { lRSS.ForeColor = value; } } Settings form: public Settings(ThemeableForm requestingForm) { rssReaderMain = requestingForm as ThemeableForm; InitializeComponent(); } private ThemeableForm rssReaderMain = null; private void button2_Click(object sender, EventArgs args) { // Appearence settings for DEFAULT THEME if (cbThemeSelect.SelectedIndex == 1) { this.rssReaderMain.LRSSBGProperty = Color.DarkSeaGreen; this.rssReaderMain.LRSSFGProperty = Color.White; } Now the all the controls in my get/set (lRSS in the example code above) error out with does not exist in the current context. I also get the warning: Warning 1The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: Form1 --- The base class 'RSSReader_BKRF.ThemeableForm' could not be loaded. Ensure the assembly has been referenced and that all projects have been built. 0 0

  • Need suggestions on how to extract data from .docx/.doc file then into mssql

    - by DarkPP
    I'm suppose to develop an automated application for my project, it will load past-year examination/exercises paper (word file), detect the sections accordingly, extract the questions and images in that section, and then store the questions and images into the database. (Preview of the question paper is at the bottom of this post) So I need some suggestions on how to extract data from a word file, then inserting them into a database. Currently I have a few methods to do so, however I have no idea how I could implement them when the file contains textboxes with background image. The question has to link with the image. Method One (Make use of ms office interop) Load the word file - Extract image, save into a folder - Extract text, save as .txt - Extract text from .txt then store in db Question: How i detect the section and question. How I link the image to the question. Extract text from word file (Working): private object missing = Type.Missing; private object sFilename = @"C:\temp\questionpaper.docx"; private object sFilename2 = @"C:\temp\temp.txt"; private object readOnly = true; object fileFormat = Word.WdSaveFormat.wdFormatText; private void button1_Click(object sender, EventArgs e) { Word.Application wWordApp = new Word.Application(); wWordApp.DisplayAlerts = Word.WdAlertLevel.wdAlertsNone; Word.Document dFile = wWordApp.Documents.Open(ref sFilename, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); dFile.SaveAs(ref sFilename2, ref fileFormat, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,ref missing, ref missing,ref missing,ref missing,ref missing,ref missing, ref missing,ref missing); dFile.Close(ref missing, ref missing, ref missing); } Extract image from word file (Doesn't work on image inside textbox): private Word.Application wWordApp; private int m_i; private object missing = Type.Missing; private object filename = @"C:\temp\questionpaper.docx"; private object readOnly = true; private void CopyFromClipbordInlineShape(String imageIndex) { Word.InlineShape inlineShape = wWordApp.ActiveDocument.InlineShapes[m_i]; inlineShape.Select(); wWordApp.Selection.Copy(); Computer computer = new Computer(); if (computer.Clipboard.GetDataObject() != null) { System.Windows.Forms.IDataObject data = computer.Clipboard.GetDataObject(); if (data.GetDataPresent(System.Windows.Forms.DataFormats.Bitmap)) { Image image = (Image)data.GetData(System.Windows.Forms.DataFormats.Bitmap, true); image.Save("C:\\temp\\DoCremoveImage" + imageIndex + ".png", System.Drawing.Imaging.ImageFormat.Png); } } } private void button1_Click(object sender, EventArgs e) { wWordApp = new Word.Application(); wWordApp.Documents.Open(ref filename, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); try { for (int i = 1; i <= wWordApp.ActiveDocument.InlineShapes.Count; i++) { m_i = i; CopyFromClipbordInlineShape(Convert.ToString(i)); } } finally { object save = false; wWordApp.Quit(ref save, ref missing, ref missing); wWordApp = null; } } Method Two Unzip the word file (.docx) - Copy the media(image) folder, store somewhere - Parse the XML file - Store the text in db Any suggestion/help would be greatly appreciated :D Preview of the word file: (backup link: http://i.stack.imgur.com/YF1Ap.png)
