  • stop android emulator call

    - by Shahzad Younis
    I am working on an Android application, having functionality like voicemail. I am using BroadcastReceiver to get dialing events. I have to get the event "WHEN CALL IS UNANSWERED (not picked after few rings) FROM RECEIVER". I will do some actions on caller end against this event. I am using AVD emulator, and I do call from one instance to another instance and it calls perfectly, but the problem is: It continuously calls until I reject or accept the call. This way I cannot detect that "CALL IS UNANSWERED AFTER A NUMBER OF RINGS". So I want the Caller emulator to drop the call after a number of rings (if unanswered) like a normal phone. I can do it (drop the call after some time) by writing some code, but I need the natural functionality of phone in the emulator. Can anyone please guide me? Is there any settings in the emulator? Or something else? The code is shown below in case it helps: public class MyPhoneReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Bundle extras = intent.getExtras(); if (extras != null) { String state = "my call state = " + extras.getString(TelephonyManager.EXTRA_STATE); Log.w("DEBUG", state); } }

  • Calculated group-by fields in MongoDB

    - by Navin Viswanath
    For this example from the MongoDB documentation, how do I write the query using MongoTemplate? db.sales.aggregate( [ { $group : { _id : { month: { $month: "$date" }, day: { $dayOfMonth: "$date" }, year: { $year: "$date" } }, totalPrice: { $sum: { $multiply: [ "$price", "$quantity" ] } }, averageQuantity: { $avg: "$quantity" }, count: { $sum: 1 } } } ] ) Or in general, how do I group by a calculated field?

  • How to establish a socket connection from iPhone to a Apache server and communicate via PHP?

    - by candoyo
    Hi, I am working on an iPhone game which is depended on a LAMP server. I want to create a "event" based system where the apache server sends an event to the iphone. For this, I am thinking of using "CFStreamCreatePairWithSocketToHost" to connect to port 80 of the apache server. I am able to successfully connect to the server and open a read and write stream via the iPhone, but I am not sure how to send data to the iphone using PHP running from the LAMP server to the iPhone. I think I can use fsockopen in php to open a socket connection and write data to that socket. I tired running this code $fp = fsockopen("tcp://localhost", 80, $errno, $errstr); if (!$fp) { echo "ERROR: $errno - $errstr<br />\n"; } else { echo"writing to socket "; fwrite($fp, "wwqeqweqw eqwe qwe \n"); //echo fread($fp, 26); fclose($fp); echo "done"; } But, I dont see anything being read on the iphone.. Any idea what's going on, or how to accomplish this? Thanks!

  • Exporting classes containing std:: objects (vector, map, etc) from a dll

    - by RnR
    I'm trying to export classes from a DLL that contain objects such as std::vectors and std::stings - the whole class is declared as dll export through: class DLL_EXPORT FontManager { The problem is that for members of the complex types I get this warning: warning C4251: 'FontManager::m__fonts' : class 'std::map<_Kty,_Ty' needs to have dll-interface to be used by clients of class 'FontManager' with [ _Kty=std::string, _Ty=tFontInfoRef ] I'm able to remove some of the warnings by putting the following forward class declaration before them even though I'm not changing the type of the member variables themselves: template class DLL_EXPORT std::allocator<tCharGlyphProviderRef>; template class DLL_EXPORT std::vector<tCharGlyphProviderRef,std::allocator<tCharGlyphProviderRef> >; std::vector<tCharGlyphProviderRef> m_glyphProviders; Looks like the forward declaration "injects" the DLL_EXPORT for when the member is compiled but is it safe? Does it realy change anything when the client compiles this header and uses the std container on his side? Will it make all future uses of such a container DLL_EXPORT (and possibly not inline?)? And does it really solve the problem that the warning tries to warn about? Is this warning anything I should be worried about or would it be best to disable it in the scope of these constructs? The clients and the dll will always be built using the same set of libraries and compilers and those are header only classes... I'm using Visual Studio 2003 with the standard STD library. ---- Update ---- I'd like to target you more though as I see the answers are general and here we're talking about std containers and types (such as std::string) - maybe the question really is: Can we disable the warning for standard containers and types available to both the client and the dll through the same library headers and treat them just as we'd treat an int or any other built-in type? (It does seem to work correctly on my side.) If so would should be the conditions under which we can do this? Or should maybe using such containers be prohibited or at least ultra care taken to make sure no assignment operators, copy constructors etc will get inlined into the dll client? In general I'd like to know if you feel designing a dll interface having such objects (and for example using them to return stuff to the client as return value types) is a good idea or not and why - I'd like to have a "high level" interface to this functionality... maybe the best solution is what Neil Butterworth suggested - creating a static library?

  • Best practice to create WPF wrapper application displaying screens on demand.

    - by Robbie
    Context: I'm developing a WPF application which will contain a lot of different "screens". Each screen contains a which on its turn contains all the visual elements. Some elements trigger events (e.g., checkboxes), a screen has individual resources, etc. The main application is "wrapper" around these screens: it contains a menubar, toolbar, statusbar and alike (in a DockPanel) and space to display one screen. Through the menubar, the user can choose which screen he wants to display. Goal: I want to dynamically load & display & (event)handle one screen in the space in the main application. I don't want to copy & paste all the "wrapper" stuff in all the different screens. And As I have many complex screens (around 300 - luckily auto-generated), I don't want to load all of them at the start of the application, but only upon request. Question: What do you recommend as the best way to realize this? What kind of things should I use and investigate: Pages or windows or User Control for the screens? Does this affect the event handling?

  • SQL Server 2008 Optimization

    - by hgulyan
    I've learned today, if you append to your query OPTION (MAXDOP 0) your query will run on multiple processors and if it's huge query, query will perform faster. I know general guidelines on query optimizations (using indexes, selecting only needed fields etc.), my question is about SQL Server optimization. Maybe changing some options in configurations or anything else. What guidelines are there for SQL Server Optimization? Thank you.

  • Cucumber and Silverlight 4

    - by weijiajun
    So I am wondering if anyone is familiar or has done any work with cucumber and Silverlight. I currently have a template directory and build file that will create RSpec tests using Bacon (light weight RSpec). I have been looking into SpecFlow and Cuke2Nuke but almost everything I have seen works with general .net code not silverlight code. Thanks.

  • Why am I getting "Message sent to deallocated instance" in Objective-C?

    - by Dave C
    I have several buttons on my app that are being created dynamically. They are all pointed at the button click event when pressed. When the button pressed method is called, the sender's tag (int value) is parsed into the controller's house ID. It works with one of the buttons — the first one created, to be specific — but the others throw the following error: -[CFNumber intValue]: message sent to deallocated instance 0xc4bb0ff0 I am not releasing these buttons anywhere in my code. I haven't set them to autorelease or anything like that. I'm just wondering why they are doing this on the click. The button click event: - (IBAction) ButtonClick: (id) sender { HouseholdViewController *controller = [[HouseholdViewController alloc] initWithNibName:@"HouseholdViewController" bundle:nil]; controller.delegate = self; controller.HouseID = [(NSInteger)[(UIButton *)sender tag] intValue]; //this line throws an error controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Where I am creating the buttons: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(MyLongInScreenCoords, MyLatInScreenCoords, 50, 50); UIImage *buttonImageNormal = [UIImage imageNamed:@"blue_pin.png"]; UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:50 topCapHeight:50]; [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal]; [self.view addSubview:button]; button.tag = [NSNumber numberWithInt:[[words objectAtIndex: i] intValue]]; ButtonPoints[CurrentHouseCount][0] = button; ButtonPoints[CurrentHouseCount][1] = [NSValue valueWithCGPoint:CGPointMake(MyActualLat, MyActualLong)]; [button addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside]; CurrentHouseCount++;

  • What Getters and Setters should and shouldn't do.

    - by cyclotis04
    I've run into a lot of differing opinions on Getters and Setters lately, so I figured I should make it into it's own question. A previous question of mine received an immediate comment (later deleted) that stated setters shouldn't have any side effects, and a SetProperty method would be a better choice. Indeed, this seems to be Microsoft's opinion as well. However, their properties often raise events, such as Resized when a form's Width or Height property is set. OwenP also states "you shouldn't let a property throw exceptions, properties shouldn't have side effects, order shouldn't matter, and properties should return relatively quickly." Yet Michael Stum states that exceptions should be thrown while validating data within a setter. If your setter doesn't throw an exception, how could you effectively validate data, as so many of the answers to this question suggest? What about when you need to raise an event, like nearly all of Microsoft's Control's do? Aren't you then at the mercy of whomever subscribed to your event? If their handler performs a massive amount of information, or throws an error itself, what happens to your setter? Finally, what about lazy loading within the getter? This too could violate the previous guidelines. What is acceptable to place in a getter or setter, and what should be kept in only accessor methods?

  • How to properly set button phase after dragging over button?

    - by irobeth
    I have a class (mxml) that extends Button while implementing drag/drop support. When I drag one of them onto another, the drag receiver stays stuck in its 'over' phase until I click on it (As if something about DragManager.acceptDragDrop is preventing the MouseEvent from getting to button) Is there a way to make a button re-evaluate its phase after the drop? I've tried fabricating a MouseEvent and sending it to rollOverHandler with no luck. This resembles the scenario in Button.as (lines 2606-2647) described like Drag over and up mouse down while out of Button roll over Button - stay in "up" phase mouse up while over Button - "over" phase continue with step 2 of first three sequences above This is my drag/drop handler private function dragDropHandler(event:DragEvent):void { trace("dropped"); var ib : IconButton = (event.dragInitiator as IconButton); if(this.data is Section) { if(ib.data is Item) { trace("ITEM"); //move an item into a section. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } else if(ib.data is Section) { trace("SECTION"); //change a section's parent. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } } //you can only drag stuff into sections. }

  • calling java script function then C# function after clicking ASP.NET button

    - by Eyla
    I have this serious: I have ASP.NET page, This page contents Update panel with ASP.NET control. I have Java script function to do validation so when I click the button I will use onclientclick to call the java function to do the validation and after this one done should call then event click button function from code behind. I tried vew methods but they did not work for me. here is sample of my code that after I click the button onclientclick will call the java script function for validation and if the validation is OK should call onclick event. .................... java script function ........................ <script type="text/javascript" > function add(){ if (tag == trye) { document.getElementById('<%=btnInfor.ClientID%>').click(); alert("DataAdded") } else { alert("Requiered Field Missing.") return false; } } </script> ..................... ASP.NET button ................... <asp:Button ID="btnInfor" runat="server" Text="Add Information" Style="position: absolute; top: 1659px; left: 433px;" onclientclick="JavaScript: return myAdd()" /> .................... code behind in C# ...................... protected void btnInfor_Click(object sender, EventArgs e) { \\mycode }

  • How can I find out if the MainActivity is being paused from my Java class?

    - by quinestor
    I am using motion sensor detection in my application. My design is this: a class gets the sensor services references from the main activity and then it implements SensorEventListener. That is, the MainActivity does not listen for sensor event changes: public void onCreate(Bundle savedInstanceState) { // ... code mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); // The following is my java class, it does not extends any android fragment/activty mShakeUtil = new ShakeUtil(mSensorManager,mAccelerometer,this); // ..more code.. } I can't redesign ShakeUtil so it is a fragment nor activity, unfortunately. Now to illustrate the problem consider: MainActivity is on its way to be destroyed/paused. I.e screen rotation ShakeUtil's onSensorChanged(SensorEvent event) gets called in the process.. One of the things that happen inside onSensorChanged is a dialog interaction, which gives the error: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState When the previous happens between MainActivity's onSaveInstanceState and onPause. I know this can be prevented if I successfully detect that MainActivity is being pause in ShakeUtil. How can I detect that MainActivity is being paused or onSaveInstanceState was called from ShakeUtil? Alternatively, how can I avoid this issue without making Shakeutil extend activity? So far I have tried with flag variables but that isn't good enough, I guess these are not atomic operations. I tried using Activity's isChangingConfigurations(), but I get an undocummented "NoSuchMethodFound" error.. I am unregistering the sensors by calling ShakeUtil when onPause in main ACtivity

  • effective functional sort

    I'm programming a function for a TI-NSpire, so I can't use the builtins from inside a function. What is the most generally efficient algorithm for sorting a list of numbers without modifying the list itself? (recursion and list-splitting are fair game, as is general use of math.)

  • doubt in javascript name validation

    - by raja
    Hi: I am using the below validation for textbox which accepts only alphabets and maximum of 50 characters. I am passing the object directly in the parameter. The below case by giving the field name i.e "my_text" directly is working is working fine. But if i pass it in variable, that time it is not working(commented the if statement). Please help me. My requirement is each time when we enter the charater, the hardcode field name should not be used in the validation. <html><head> <script language=JavaScript> function check_length(my_form,fieldName) { alert(fieldName); // if (my_form.fieldName.value.length >= maxLen) { if (my_form.my_text.value.length >= maxLen) { var msg = "You have reached your maximum limit of characters allowed"; alert(msg); my_form.my_text.value = my_form.my_text.value.substring(0, maxLen); } else{ var keyCode = window.event.keyCode; if ((keyCode < 65 || keyCode > 90) && (keyCode < 97 || keyCode > 123) && keyCode != 32) { window.event.returnValue = false; alert("Enter only Alphabets"); } my_form.text_num.value = maxLen - my_form.my_text.value.length;} } </script> </head> <body> <form name=my_form method=post> <input type="text" onKeyPress=check_length(this.form,this.name); name=my_text rows=4 cols=30> <br> <input size=1 value=50 name=text_num> Characters Left </form> </body> </html>

  • .NET MissingMethodException occuring on one of thousands of end-user machines -- any insight?

    - by Yoooder
    This issue has me baffled, it's affecting a single user (to my knowledge) and hasn't been reproduced by us... The user is receiving a MissingMethodException, our trace file indicates it's occuring after we create a new instance of a component, when we're calling an Initialize/Setup method in preparation to have it do work (InitializeWorkerByArgument in the example) The Method specified by the error is an interface method, which a base class implements and classes derived from the base class can override as-needed The user has the latest release of our application All the provided code is shipped within a single assembly Here's a very distilled version of the component: class Widget : UserControl { public void DoSomething(string argument) { InitializeWorkerByArgument(argument); this.Worker.DoWork(); } private void InitializeWorkerByArgument(string argument) { switch (argument) { case "SomeArgument": this.Worker = new SomeWidgetWorker(); break; } // The issue I'm tracking down would have occured during "new SomeWidgetWorker()" // and would have resulted in a missing method exception stating that // method "DoWork" could not be found. this.Worker.DoWorkComplete += new EventHandler(Worker_DoWorkComplete); } private IWidgetWorker Worker { get; set; } void Worker_DoWorkComplete(object sender, EventArgs e) { MessageBox.Show("All done"); } } interface IWidgetWorker { void DoWork(); event EventHandler DoWorkComplete; } abstract class BaseWorker : IWidgetWorker { virtual public void DoWork() { System.Threading.Thread.Sleep(1000); RaiseDoWorkComplete(this, null); } internal void RaiseDoWorkComplete(object sender, EventArgs e) { if (DoWorkComplete != null) { DoWorkComplete(this, null); } } public event EventHandler DoWorkComplete; } class SomeWidgetWorker : BaseWorker { public override void DoWork() { System.Threading.Thread.Sleep(2000); RaiseDoWorkComplete(this, null); } }

  • ASP.net MVC Routing on Postback

    - by Mark Kadlec
    In my ASP.net MVC View I have a dropdown that I want to get details on selection and asynchronously update a div. My aspx is as follows: <% using (Html.BeginForm("Index", "Portal", FormMethod.Post, new { id = "TheForm" })) {%> <h2>Index</h2> <% using (Ajax.BeginForm("Details", new AjaxOptions { UpdateTargetId = "mpkResults" })) { %> <%=Html.DropDownList("Docs", (IEnumerable<SelectListItem>)ViewData["Docs"], new { onchange = "document.getElementById('TheForm').submit();" })%> <p><input type="submit" value="Details" /></p> <% } %> <div id="mpkResults" style="margin:10px 0px 0px 0px;"></div> ... The onchange event fires correctly on selection of the dropdown, but instead of the Details method in my code behind firing, it hits my Index method. Why is the details method not getting hit on the onchange event? My Details() method in the controller is: public ActionResult Details() { ... < It never gets here, just goes to the index() method } It's a little frustrating right now since I'm sure it is a simple mistake but not sure what it could be. I looked at the Source of my page and sure enough, the form looks like it should be routing to the Details Action: <form action="/Portal/Details" method="post" ... Any help would be appreciated.

  • What is a de-compiler how does it work?

    So is a decompiler really a thing that gives gives the source of a compiled/interpreted piece of code? Because to me that sounds impossible. How would you get the names of the functions, variables, classes, etc if it is compiled. Or am I misinterpreting the definition? How does it work? And what is the general principal behind making one?

  • Eclipse vs Netbeans

    - by Zenzen
    Some time ago (~4-5months ago) I attented a lecture about JEE and at some point the lecturer started talking about webservices and how hard it is to create a good one because all the IDEs make them in a bit different way (or something like that) and that in general it's better to use Netbeans to create them as Eclipse has some issues, the thing is he didn't really say why Eclipse is bad. Now I'm wondering is what he said true and why, is it really better to use Netbeans for webservices and why?

  • [AS3] Calling Php Script with UTF-8 POST variables

    - by kornelijepetak
    AS3 documentation says that Strings in AS3 are in UTF-16 format. There is a textbox on a Flash Clip where user can type some data. When a button is clicked, I want this data to be sent to a php script. I have everything set up, but it seems that the PHP script gets the data in UTF-16 format. The data in the database (which is utf-8) shows some unrecognizable characters (where special characters are used), meaning that the data has not been sent in a correct encoding. var variables:URLVariables=new URLVariables; var varSend:URLRequest=new URLRequest("http://website.com/systematic/accept.php"); varSend.method=URLRequestMethod.POST; varSend.data=variables; var varLoader:URLLoader=new URLLoader; varLoader.dataFormat=URLLoaderDataFormat.VARIABLES; varLoader.addEventListener(Event.COMPLETE, completeHandler); When submit button is clicked, the following handler gets executed. function sendData(event:MouseEvent) : void { // i guess here is the problem (tbName.text is UTF-16) variables.name = tbName.text; varLoader.load(varSend); } Is there any way to send the data so that PHP script gets the data in UTF-8 format? (PHP script is retrieving the value using the $_POST['name']).
