  • Does anyone know why my maps only show grid

    - by NickTFried
    I've doubled checked my API key is right and that is right I doubled checked that it was correct. Here is my source and XML could anyone check to see what is wrong. Also I make sure I have internet. <?xml version="1.0" encoding="utf-8"?> <uses-permission android:name="android.permissions.INTERNET"/> <uses-permission android:name="android.permissions.ACCESS_FINE_LOCATION"/> <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="com.google.android.maps" /> <activity android:name=".CadetCommand" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="RedLight"></activity> <activity android:name="PTCalculator"></activity> <activity android:name="LandNav"></activity> </application> <uses-sdk android:minSdkVersion="4"/> package edu.elon.cs.mobile; import com.google.android.maps.MapActivity; import com.google.android.maps.MapView; import android.os.Bundle; public class LandNav extends MapActivity{ public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.landnav); } @Override protected boolean isRouteDisplayed() { return false; } }

  • Components don't show in custom JPanel/JComponent

    - by Bart van Heukelom
    I've created a custom swing component. I can see it (the grid from the paint method is drawn), but the buttons that are added (verified by println) aren't shown. What am I doing wrong? Background information: I'm trying to build a tree of visible objects like the Flash/AS3 display list. public class MapPanel extends JComponent { // or extends JPanel, same effect private static final long serialVersionUID = 4844990579260312742L; public MapPanel(ShapeMap map) { setBackground(Color.LIGHT_GRAY); setPreferredSize(new Dimension(1000,1000)); setLayout(null); for (Layer l : map.getLayers()) { // LayerView layerView = new LayerView(l); // add(layerView); System.out.println(l); JButton test = new JButton(l.getName()); add(test); validate(); } } @Override protected void paintComponent(Graphics g) { // necessary? super.paintComponent(g); // background g.setColor(getBackground()); g.fillRect(0, 0, getWidth(), getHeight()); // grid g.setColor(Color.GRAY); for (double x = 0; x < getWidth(); x += 10) { g.drawLine((int)x, 0, (int)x, getHeight()); } for (double y = 0; y < getHeight(); y += 10) { g.drawLine(0, (int)y, getWidth(), (int)y); } } }

  • Best practice to structure large html-based project

    - by AntonAL
    I develop Rails based website, enjoying using partials for some common "components" Recently, i faced a problem, that states with CSS interference. Styles for one component (described in css) override styles for another components. For example, one component has ... <ul class="items"> ... and another component has it too. But that ul's has different meaning in these two components. On the other hand, i want to "inherit" some styles for one component from another. For example: Let, we have one component, called "post" <div class="post"> <!-- post's stuff --> <ul class="items"> ... </ul> </div And another component, called "new-post": <div class="new-post"> <!-- post's stuff --> <ul class="items"> ... </ul> <!-- new-post's stuff --> <div class="tools">...</div> </div Post and new-post have something similar ("post's stuff") and i want to make CSS rules to handle both "post" and "new-post" New post has "subcomponents", for example - editing tools, that has also: <ul class="items"> This is where CSS rules starting to interfer - some rules, targeted for ul.items (in post and new-post) applies subcomponent of new-post, called "tools" On the one hand - i want to inherit some styles On the other hand, i want to get better incapsulation What are the best practices, to avoid such kind of problems ?

  • Different behaviour of method overloading in C#

    - by Wondering
    Hi All, I was going through C# Brainteasers(http://www.yoda.arachsys.com/csharp/teasers.html) and came accross one question:what should be the o/p of below code class Base { public virtual void Foo(int x) { Console.WriteLine ("Base.Foo(int)"); } } class Derived : Base { public override void Foo(int x) { Console.WriteLine ("Derived.Foo(int)"); } public void Foo(object o) { Console.WriteLine ("Derived.Foo(object)"); } } class Test { static void Main() { Derived d = new Derived(); int i = 10; d.Foo(i); // it prints ("Derived.Foo(object)" } } but if I change the code to enter code here class Derived { public void Foo(int x) { Console.WriteLine("Derived.Foo(int)"); } public void Foo(object o) { Console.WriteLine("Derived.Foo(object)"); } } class Program { static void Main(string[] args) { Derived d = new Derived(); int i = 10; d.Foo(i); // prints Derived.Foo(int)"); Console.ReadKey(); } } I want to why the o/p is getting changde when we are inheriting vs not inheriting , why method overloading is behaving differently in both the cases

  • Xerces C++ SAX Parsing Problem: expected class-name before '{' token

    - by aduric
    I'm trying to run through an example given for the C++ Xerces XML library implementation. I've copied the code exactly, but I'm having trouble compiling it. error: expected class-name before '{' token I've looked around for a solution, and I know that this error can be caused by circular includes or not defining a class before it is used, but as you can see from the code, I only have 2 files: MySAXHandler.hpp and MySAXHandler.cpp. However, the MySAXHandler class is derived from HandlerBase, which is included. MyHandler.hpp #include <xercesc/sax/HandlerBase.hpp> class MySAXHandler : public HandlerBase { public: void startElement(const XMLCh* const, AttributeList&); void fatalError(const SAXParseException&); }; MySAXHandler.cpp #include "MySAXHandler.hpp" #include <iostream> using namespace std; MySAXHandler::MySAXHandler() { } void MySAXHandler::startElement(const XMLCh* const name, AttributeList& attributes) { char* message = XMLString::transcode(name); cout << "I saw element: "<< message << endl; XMLString::release(&message); } void MySAXHandler::fatalError(const SAXParseException& exception) { char* message = XMLString::transcode(exception.getMessage()); cout << "Fatal Error: " << message << " at line: " << exception.getLineNumber() << endl; XMLString::release(&message); } I'm compiling like so: g++ -L/usr/local/lib -lxerces-c -I/usr/local/include -c MySAXHandler.cpp I've looked through the HandlerBase and it is defined, so I don't know why I can't derive a class from it? Do I have to override all the virtual functions in HandlerBase? I'm kinda new to C++. Thanks in advance.

  • MyContainer derived from FrameworkElement with binding support.

    - by alex2k8
    To understand how the binding works, I implemented MyContainer derived from FrameworkElement. This container allowes to set Children and adds them into the logical tree. But the binding by ElementName does not work. What can I do with MyContainer to make it work, leaving the parent as FrameworkElement? C#: public class MyContainer : FrameworkElement { public MyContainer() { Children = new List<FrameworkElement>(); } public List<FrameworkElement> Children { get; set; } protected override IEnumerator LogicalChildren { get { return Children.GetEnumerator(); } } } XAML: <Window x:Class="WpfLogicalTree.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfLogicalTree" Title="Window1" Height="300" Width="300"> <StackPanel> <local:MyContainer> <local:MyContainer.Children> <TextBlock Text="Foo" x:Name="_source" /> <TextBlock Text="{Binding Path=Text, ElementName=_source}" x:Name="_target"/> </local:MyContainer.Children> </local:MyContainer> <Button Click="Button_Click">Test</Button> </StackPanel> </Window> Window1.cs private void Button_Click(object sender, RoutedEventArgs e) { MessageBox.Show(_target.Text); }

  • Best way to determine variable type and treat each one differently in F#

    - by James Black
    I have a function that will create a select where clause, but right now everything has to be a string. I would like to look at the variable passed in and determine what type it is and then treat it properly. For example, numeric values don't have single quotes around them, option type will either be null or have some value and boolean will actually be zero or one. member self.BuildSelectWhereQuery (oldUser:'a) = let properties = List.zip oldUser.ToSqlValuesList sqlColumnList let init = false, new StringBuilder() let anyChange, (formatted:StringBuilder) = properties |> Seq.fold (fun (anyChange, sb) (oldVal, name) -> match(anyChange) with | true -> true, sb.AppendFormat(" AND {0} = '{1}'", name, oldVal) | _ -> true, sb.AppendFormat("{0} = '{1}'", name, oldVal) ) init formatted.ToString() Here is one entity: type CityType() = inherit BaseType() let mutable name = "" let mutable stateId = 0 member this.Name with get() = name and set restnameval=name <- restnameval member this.StateId with get() = stateId and set stateidval=stateId <- stateidval override this.ToSqlValuesList = [this.Name; this.StateId.ToString()] So, if name was some other value besides a string, or stateId can be optional, then I have two changes to make: How do I modify ToSqlValuesList to have the variable so I can tell the variable type? How do I change my select function to handle this? I am thinking that I need a new function does the processing, but what is the best FP way to do this, rather than using something like typeof?

  • Android map performance with > 800 overlays of KML data

    - by span
    I have some a shape file which I have converted to a KML file that I wish to read coordinates from and then draw paths between the coordinates on a MapView. With the help of this great post: How to draw a path on a map using kml file? I have been able to read the the KML into an ArrayList of "Placemarks". This great blog post then showed how to take a list of GeoPoints and draw a path: http://djsolid.net/blog/android---draw-a-path-array-of-points-in-mapview The example in the above post only draws one path between some points however and since I have many more paths than that I am running into some performance problems. I'm currently adding a new RouteOverlay for each of the separate paths. This results in me having over 800 overlays when they have all been added. This has a performance hit and I would love some input on what I can do to improve it. Here are some options I have considered: Try to add all the points to a List which then can be passed into a class that will extend Overlay. In that new class perhaps it would be possible to add and draw the paths in a single Overlay layer? I'm not sure on how to implement this though since the paths are not always intersecting and they have different start and end points. At the moment I'm adding each path which has several points to it's own list and then I add that to an Overlay. That results in over 700 overlays... Simplify the KML or SHP. Instead of having over 700 different paths, perhaps there is someway to merge them into perhaps 100 paths or less? Since alot of paths are intersected at some point it should be possible to modify the original SHP file so that it merges all intersections. Since I have never worked with these kinds of files before I have not been able to find a way to do this in GQIS. If someone knows how to do this I would love for some input on that. Here is a link to the group of shape files if you are interested: http://danielkvist.net/cprg_bef_cbana_polyline.shp http://danielkvist.net/cprg_bef_cbana_polyline.shx http://danielkvist.net/cprg_bef_cbana_polyline.dbf http://danielkvist.net/cprg_bef_cbana_polyline.prj Anyway, here is the code I'm using to add the Overlays.

  • 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

  • EF/LINQ: Where() against a property of a subtype

    - by ladenedge
    I have a set of POCOs, all of which implement the following simple interface: interface IIdObject { int Id { get; set; } } A subset of these POCOs implement this additional interface: interface IDeletableObject : IIdObject { bool IsDeleted { get; set; } } I have a repository hierarchy that looks something like this: IRepository<T <: BasicRepository<T <: ValidatingRepository<T (where T is IIdObject) I'm trying to add a FilteringRepository to the hierarchy such that all of the POCOs that implement IDeletableObject have a Where(p => p.IsDeleted == false) filter applied before any other queries take place. My goal is to avoid duplicating the hierarchy solely for IDeletableObjects. My first attempt looked like this: public override IQueryable<T> Query() { return base.Query().Where(t => ((IDeletableObject)t).IsDeleted == false); } This works well with LINQ to Objects, but when I switch to an EF backend I get: "LINQ to Entities only supports casting Entity Data Model primitive types." I went on to try some fancier parameterized solutions, but they ultimately failed because I couldn't make T covariant in the following case for some reason I don't quite understand: interface IQueryFilter<out T> // error { Expression<Func<T, bool>> GetFilter(); } I'd be happy to go into more detail on my more complicated solutions if it would help, but I think I'll stop here for now in hope that someone might have an idea for me to try. Thanks very much in advance!

  • Does adding to a method group count as using a variable?

    - by Vaccano
    I have the following code example taken from the code of a Form: protected void SomeMethod() { SomeOtherMethod(this.OnPaint); } private void SomeOtherMethod(Action<PaintEventArgs> onPaint) { onPaint += MyPaint; } protected void MyPaint(PaintEventArgs e) { // paint some stuff } The second method (SomeOtherMethod) has resharper complaining at me. It says of onPaint that "Value assigned is not used in any execution path". To my mind it was used because I added a method to the list of methods called when a paint was done. But usually when resharper tells me something like this it is because I am not understanding some part of C#. Like maybe when the param goes out of goes out of scope the item I added to the list gets removed (or something like that). I thought I would ask here to see if any one knows what resharper is trying to tell me. (Side Note: I usually just override OnPaint. But I am trying to get OnPaint to call a method in another class. I don't want to expose that method publicly so I thought I would pass in the OnPaint group and add to it.)

  • Image overlapping in widget

    - by Hunt
    I am trying to create a widget in android in which when I click over image the image gets changed with a new one -- kind of toggle image. But when I click over it, the image overwrites over the old one rather then replacing the new one. I don't know whether this is the way the widget works or am I doing something wrong. My images are semi-transparent so in case one overrides another one can see the image which is being overlapped. This is the code that I have written in OnReceive by overriding it: @Override public void onReceive(Context context, Intent intent){ if (intent.getAction().equals(iAlertConstant.ACTION_WIDGET_UPDATE_FROM_WIDGET)) { RemoteViews remoteViews = new RemoteViews(context.getPackageName(),R.layout.mywidget); remoteViews.setImageViewResource(R.id.btnOnOff,R.drawable.offbtn); ComponentName thisWidget = new ComponentName(context, EmergencyWidget.class); AppWidgetManager.getInstance(context).updateAppWidget(thisWidget, remoteViews); } else super.onReceive(context, intent); } Layout <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:background="@drawable/widget_background" android:paddingLeft="10.0dip" android:paddingTop="8.0dip" android:paddingRight="10.0dip" android:paddingBottom="8.0dip" android:layout_width="fill_parent" android:layout_height="72dp" android:layout_marginLeft="10.0dip" android:layout_marginTop="10.0dip" android:layout_marginRight="10.0dip" android:id="@+id/emergencyWidget" android:orientation="horizontal"> <ImageView android:background="@drawable/offbtn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="7dp" android:layout_marginLeft="4dp" android:layout_marginRight="4dp" android:layout_gravity="right" android:id="@+id/btnOnOff" /> </LinearLayout>

  • Unable to step into interface implementation configured by unity application block

    - by Rahul
    I have configured a set of interface implementations with EntLib. unity block. The constructor of implementation classes work fine as soon as I run the application: 1. The interface to implement when I run the application the cctor runs fine, which shows that unity resolution was successful: But when I try to call a method of this class, the code just passes through without actually invoking the function of the implemented class: Edit: Added on June 11, 2012 Following is the Unity Configuration I have. (This is all the unity configuration I am doing) public class UnityControllerFactory : DefaultControllerFactory { private static readonly IUnityContainer container; private static UnityControllerFactory factory = null; static UnityControllerFactory() { container = new UnityContainer(); UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); section.Configure(container); factory = new UnityControllerFactory(); } public static UnityControllerFactory GetControllerFactory() { return factory; } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { return container.Resolve(controllerType) as IController; } } I am unable to step into this code and the implementation simply skips out without executing anything. What is wrong here?

    I am a new guy in Android. How to implement the Geo-tag for images? I have tried by myself but not getting expected result. My code is like: @Override protected Dialog onCreateDialog(int id) { jpgDialog = null;; switch(id){ case ID_JPGDIALOG: Context mContext = this; jpgDialog = new Dialog(mContext); jpgDialog.setContentView(R.layout.jpgdialog); exifText = (TextView) jpgDialog.findViewById(R.id.text); geoText = (TextView)jpgDialog.findViewById(R.id.geotext); bmImage = (ImageView)jpgDialog.findViewById(R.id.image); bmOptions = new BitmapFactory.Options(); bmOptions.inSampleSize = 2; Button okDialogButton = (Button)jpgDialog.findViewById(R.id.okdialogbutton); okDialogButton.setOnClickListener(okDialogButtonOnClickListener); mapviewButton = (Button)jpgDialog.findViewById(R.id.mapviewbutton); mapviewButton.setOnClickListener(mapviewButtonOnClickListener); break; default: break; } return jpgDialog; } Please help me how to proceed?

  • onDestroy() won't get called after this.finish()

    - by steff
    Hi everyone, I'm wondering why the Motorola Milestone with 2.1-update1 behaves differently from the Emulator or e.g. the Nexus One. I am trying to exit my app with: @Override protected void onPause() { if(mayDestroyActivity) this.finish(); super.onPause(); } This works well on either Emulator or Nexus One. onDestroy() gets called immediatly after onPause() and onStop. But not for the Milestone. Instead, onDestroy() gets called when another Activity is started. Its section in the Manifest looks like this: <activity android:name=".MyActivity" android:configChanges="orientation|keyboardHidden" android:label="@string/questionnaire_item" android:launchMode="singleInstance" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:windowSoftInputMode="adjustPan"> <intent-filter> <category android:name="android.intent.category.OPENABLE" /> </intent-filter> </activity> Does anyone have a hint on this? My app depends on exiting properly since I save all progress in onDestroy() Thanks, Steff

  • Force close on clicking on radio button

    Whenever I try to press a radio button on my emulator, it just force closes! public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button b = (Button)this.findViewById(R.id.btn_confirm); b.setOnClickListener(this); RadioButton radio_ctf = (RadioButton) findViewById(R.id.radio_ctf); RadioButton radio_ftc = (RadioButton) findViewById(R.id.radio_ftc); radio_ctf.setOnClickListener(this); radio_ftc.setOnClickListener(this); } @Override public void onClick(View v) { TextView tv = (TextView)this.findViewById(R.id.tv_result); EditText et = (EditText)this.findViewById(R.id.et_name); RadioButton radio_ctf = (RadioButton) findViewById(R.id.radio_ctf); RadioButton radio_ftc = (RadioButton) findViewById(R.id.radio_ftc); double y = 0; int x = Integer.parseInt(et.getText().toString()); if(radio_ctf.isChecked()) { y = ((double)x * 1.8) + 32; } if(radio_ftc.isChecked()) { y = ((double)x - 32) * 0.555; } String text = "Result:" + y; tv.setText(text);

  • Applying the Decorator Pattern to Forms

    - by devoured elysium
    I am trying to apply the Decorator Design Pattern to the following situation: I have 3 different kind of forms: Green, Yellow, Red. Now, each of those forms can have different set of attributes. They can have a minimize box disabled, a maximized box disabled and they can be always on top. I tried to model this the following way: Form <---------------------------------------FormDecorator /\ /\ |---------|-----------| |----------------------|-----------------| GreenForm YellowForm RedForm MinimizeButtonDisabled MaximizedButtonDisabled AlwaysOnTop Here is my GreenForm code: public class GreenForm : Form { public GreenForm() { this.BackColor = Color.GreenYellow; } public override sealed Color BackColor { get { return base.BackColor; } set { base.BackColor = value; } } } FormDecorator: public abstract class FormDecorator : Form { private Form _decoratorForm; protected FormDecorator(Form decoratorForm) { this._decoratorForm = decoratorForm; } } and finally NoMaximizeDecorator: public class NoMaximizeDecorator : FormDecorator { public NoMaximizeDecorator(Form decoratorForm) : base(decoratorForm) { this.MaximizeBox = false; } } So here is the running code: static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(CreateForm()); } static Form CreateForm() { Form form = new GreenForm(); form = new NoMaximizeDecorator(form); form = new NoMinimizeDecorator(form); return form; } The problem is that I get a form that isn't green and that still allows me to maximize it. It is only taking in consideration the NoMinimizeDecorator form. I do comprehend why this happens but I'm having trouble understanding how to make this work with this Pattern. I know probably there are better ways of achieving what I want. I made this example as an attempt to apply the Decorator Pattern to something. Maybe this wasn't the best pattern I could have used(if one, at all) to this kind of scenario. Is there any other pattern more suitable than the Decorator to accomplish this? Am I doing something wrong when trying to implement the Decorator Pattern? Thanks

  • Android: onListItemClick not opening up the .xml file

    - by Capsud
    Hi, public void onListItemClick(ListView l, View v, int position, long id) { if(position == 0){ setContentView(R.layout.cuisine); } } I have an array of Strings and i'm using the above method to try and open up a new xml file called 'cuisine' when it is clicked. but it keeps failing! Have I done this right, or what am I doing wrong? Thanks. Ok from looking at similar problems on the web, people have said to get the onListItemClick() to start a new activity and using that new activity to then open up the new view? So what i've done is this... protected void onListItemClick(ListView l, View v, int position, long id) { Intent dundrumIntent = new Intent(v.getContext(), DundrumSelector.class); dundrumIntent.putExtra("position", position); startActivityForResult(dundrumIntent, 0); } and then import android.app.Activity; import android.os.Bundle; public class DundrumSelector extends Activity { @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); int position = getIntent().getExtras().getInt("position"); if(position == 0){ setContentView(R.layout.cuisine); } } } Yet i'm still getting the same problem. The program crashes when I click on an item in the listView. And yes i've added the activity to the manifest. Does anyone have a resolution to this as alot of people seem to be having the same problem. Thanks alot.

  • ASP.NET Response Filter to Reformat the rendered output of ASPX pages?

    - by PropellerHead
    I've created a simple HttpModule and response stream to reformat the rendered output of web pages (see code snippets below). In the HttpModule I set the Response.Filter to my PageStream: m_Application.Context.Response.Filter = new PageStream(m_Application.Context); In the PageStream I overwrite the Write method in order to do my reformatting of the rendered output: public override void Write(byte[] buffer, int offset, int count) { string html = System.Text.Encoding.UTF8.GetString(buffer); //Do some string resplace operations here... byte[] input = System.Text.Encoding.UTF8.GetBytes(html); m_DefaultStream.Write(input, 0, input.Length); } And this work fine when using it on simple HTML pages (.html), but when I use this method on ASPX pages (.aspx), the Write method is called several times, splitting up the reformatting into different steps, and potentially destroying the string replacement operations. How do I solve this? Is there a way to let the ASPX page NOT call Write several times, e.g. by changing its buffer size, or have I chosen the wrong approach entirely, by using this Response.Filter method to manipulate the rendered output?

  • NSTimer Reset Not Working

    - by user355900
    hi, i have a nstimer and it works perfectly counting down from 2:00 but when i hit the reset button it does not work it just stops the timer and when i press start again it will carry on with the timer as if it had never been stopped. Here is my code `@implementation TimerAppDelegate @synthesize window; (void)applicationDidFinishLaunching:(UIApplication *)application { timerLabel.text = @"2:00"; seconds = 120; // Override point for customization after application launch [window makeKeyAndVisible]; } (void)viewDidLoad { [timer invalidate]; } (void)countDownOneSecond { seconds--; int currentTime = [timerLabel.text intValue]; int newTime = currentTime - 1; int displaySeconds = !(seconds % 60) ? 0 : seconds < 60 ? seconds : seconds - 60; int displayMinutes = floor(seconds / 60); NSString *time = [NSString stringWithFormat:@"%d:%@%d", displayMinutes, [[NSString stringWithFormat:@"%d", displaySeconds] length] == 1 ? @"0" : @"", displaySeconds ]; timerLabel.text = time; if(seconds == 0) { [timer invalidate]; } } (void)startOrStopTimer { if(timerIsRunning){ [timer invalidate]; [startOrStopButton setTitle:@"Start" forState:UIControlStateNormal]; } else { timer = [[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countDownOneSecond) userInfo:nil repeats:YES] retain]; [startOrStopButton setTitle:@"Stop" forState:UIControlStateNormal]; } timerIsRunning = !timerIsRunning; } (void)resetTimer { [timer invalidate]; [startOrStopButton setTitle:@"Start" forState:UIControlStateNormal]; [timer invalidate]; timerLabel.text = @"2:00"; } (void)dealloc { [window release]; [super dealloc]; } @end` thanks
