  • javascript call url from different domain

    - by user246114
    Hi, I want to post some data via javascript to another domain. Something like: http://www.othersite.com/submitfunnyname?name=blah The other site (othersite.com) has a REST interface that you can call (well actually this is a get example) to submit a funny name to them. Can I do this already with javascript? I'm a little confused on this - I know if that service wants to return some data, I'd need to use something like JSON-P - even though here I'm submitting some data, I guess the service will return some message structure letting me know the result, so it would have to be JSON-P, right? Thanks

  • Call function by pointer and set parametrs in memory block

    - by Ellesmess Glain
    Hi, I've little problem : I'm solving problem with calling function by pointer and passing to it parameters in continuous memory block. My goal is to have function named e.g CallFunc(void * func,void *params, unsigned int param_length); that I'll send function pointer, pointer to function's parameters and eventually parameters length and this calling function will call passed function with it's parameters. I will like write this in C/C++, but if somebody has idea, how this resolve in other language, that supports DLL generation and exportet functions, it will be fine too. Thanks for answers, Ellesmess P.S. I'm sorry about my English, but I'm Czech, thanks :o)

  • Call Generic method using runtime type and cast return object

    - by markpirvine
    I'm using reflection to call a generic method with a type determined at runtime. My code is as follows: Type tType = Type.GetType(pLoadOut.Type); MethodInfo method = typeof(ApiSerialiseHelper).GetMethod("Deserialise", new Type[] { typeof(string) }); MethodInfo generic = method.MakeGenericMethod(tType); generic.Invoke(obj, new object[] { pLoadOut.Data }); This works ok. However the generic.Invoke method returns an object, but what I would like is the type determined at runtime. Is this possible with this approach, or is there a better option? Mark

  • How to call 3 threads sequentially many times?

    - by Hello
    How to call 3 threads sequentially many times? For example: In iteration 1, execution order should be "Thread0-thread1-thread2" then in iteration 2 should be same i.e "Thread0 - thread1-thread2" and so on. The sample code is just executing 3 threads only once. It is not going to 2nd iteration. Thread0 = CreateThread( NULL,0,ThreadProc0, NULL, CREATE_SUSPENDED, &ThreadID); Thread1 = CreateThread( NULL,0,ThreadProc1, NULL, CREATE_SUSPENDED, &ThreadID); Thread2 = CreateThread( NULL,0,ThreadProc2, NULL, CREATE_SUSPENDED, &ThreadID); for(i=0;i<iterations;i++) //Iterations in calling threads { ResumeThread(Thread0); WaitForSingleObject(Thread0, INFINITE); ResumeThread(Thread1); WaitForSingleObject(Thread1, INFINITE); ResumeThread(Thread2); WaitForSingleObject(Thread2, INFINITE); } // Close thread and semaphore handles

  • increasing speed and efficiency of ajax call

    - by user1048824
    I'm not the most disciplined dev, dont know standards and am self-taught so bear with me. I create stuff very logically and fast but not always using 'programming standards'. I have a mobile app using geolocation API. it gets thousands of places from my db and makes gmaps v3 markers for the ones around the user's current location. there is an ajax call from my JS to an aspx page that calls the database, makes a json string, and sends the json string to the javascript that then creates the google map markers. would i save time if the json string was in a flat file? im not sure if, generally speaking, accessing a sql db from an aspx page is faster than c# file i/o on a flat file with pre-rendered JSON. (of course, using the flat file, it would update everytime the db is updated)

  • Call java program on server through web request

    - by Rossella
    I need to develop an application where a Java client calls a Java application located on the server with certain parameters, the Java application on the server computes data and sends the data back to the client. Everything needs to go through port 80 on which I have a IIS webserver listening. I cannot open any other port on the server. Is there any way I can do this? The server can write files in a directory that the client can read but I am not sure how to handle the synchronization and I don't know how to call a script on the server from the client through port 80. Every suggestion would be highly appreciated Thanks a lot in advance, this problem is making me crazy

  • Call subclass constructor from abstract class in Java

    - by Joel
    public abstract class Parent { private Parent peer; public Parent() { peer = new ??????("to call overloaded constructor"); } public Parent(String someString) { } } public class Child1 extends parent { } public class Child2 extends parent { } When I construct an instance of Child1, I want a "peer" to automatically be constructed which is also of type Child1, and be stored in the peer property. Likewise for Child2, with a peer of type Child2. The problem is, on the assignment of the peer property in the parent class. I can't construct a new Child class by calling new Child1() because then it wouldn't work for Child2. How can I do this? Is there a keyword that I can use that would refer to the child class? Something like new self()?

  • Unable to call views

    - by Scott
    I'm using Sails and I when I attempt to call the login action of my UsersController. I know my routing is working, because the console.log successfully logs both the loginpassword and loginname. However, the res.view() doesn't work. Neither does returning res.view(). module.exports = { create: function(req, res) { }, destroy: function(req, res) { }, login: function(req, res) { var loginname = req.param("loginname"); var loginpassword = req.param("loginpassword"); console.log(loginname + ' ' + loginpassword); res.view(); }, logout: function(req, res) { }, _config: {} }; I have a /views/user/login.ejs and all it currently contains is a header block with some test text, but I can't get that to render at all. Any thoughts?

  • Why would Java app make RPC call to itself?

    - by amphibient
    I am working with a multithreaded homegrown multi-module app in my new job. We use the the Thrift protocol to communicate RPC calls between different stand-alone applications in a distributed system. One of them listens on multiple ports and I just noticed that it actually makes an RPC call to itself from one thread invoked from one socket it listens to (web service call) to another port within the same app. I verified that it could accomplish the same thing if it just went and directly called the method that the remote procedure ultimately invokes as it is all within the same application, same JVM. To make it even more mysterious, the call is completely synchronous, i.e. no callbacks involved. The first thread totally sits and waits until it makes a call across the wire to itself and comes back. Now, I am perplexed why anybody would do it this way. It seems like calling somebody on the phone that sits in the same room as you do. Can anybody provide an explanation why the developer before me would come up with the above mentioned model? Maybe there is a reason and I am missing something.

  • I can't delete a directory inside a junctioned directory

    - by Fredy Muñoz
    So this is the deal. A couple of days ago I moved my profile folder C:\Documents and Settings\fmunoz to a different drive D:\fmunoz. Today, I created a directory in my desktop using the point-and-click method: Right-click on an empty space in the desktop Select New Select Folder Leave the default name New Folder and press Enter I tried to delete the folder using the point-and-click method: Right-click the New Folder directory Select Delete After five seconds, I got the following message: --------------------------- Error Deleting File or Folder --------------------------- Cannot delete New Folder: Access is denied. Make sure the disk is not full or write-protected and that the file is not currently in use. --------------------------- Initially I thought that there must be some sort of indexing services locking the directory so I got a list of open files using the TuneUp Process Manager tool but the New Folder directory wasn't there. I double-clicked My Computer, navigated to the desktop directory C:\Documents and Settings\fmunoz\Destkop, tried to delete the New Folder directory using the same point-and-click method described above and got exactly the same message at the same amount of time. In the same window, I navigated to the actual location of the desktop directory D:\fmunoz\Desktop, tried to delete the New Folder directory and this time it worked. I thought that this behavior was due to some special treatment that Windows gives to the desktop or the profile directories so I tried doing the same thing with a different set of directories: Created a folder D:\dummy Created a junction C:\dummy pointing to D:\dummy Created a New Folder directory in C:\dummy Tried to delete New Folder from C:\dummy. Didn't work. Tried to delete New Folder from D:\dummy. It worked. I tried creating the folder in the actual directory rather than the junction directory: Created a New Folder directory in D:\dummy Tried to delete New Folder from C:\dummy. Didn't work. Tried to delete New Folder from D:\dummy. It worked. I also tried using the Delete button instead of using the Delete option of the context menu but it didn't work. When using the Shift+Delete sequence, it works. It also works by using the rd command in the console, but in both cases the deleted directory doesn't goes to the Recycle Bin, which is my intention when using the Delete context menu option or the Delete button.

  • Android remote service doesn't call service methods

    - by tarantel
    Hello, I'm developing a GPS tracking software on android. I need IPC to control the service from different activities. So I decide to develop a remote service with AIDL. This wasn't a big problem but now it's always running into the methods of the interface and not into those of my service class. Maybe someone could help me? Here my ADIL file: package test.de.android.tracker interface ITrackingServiceRemote { void startTracking(in long trackId); void stopTracking(); void pauseTracking(); void resumeTracking(in long trackId); long trackingState(); } And the here a short version of my service class: public class TrackingService extends Service implements LocationListener{ private LocationManager mLocationManager; private TrackDb db; private long trackId; private boolean isTracking = false; @Override public void onCreate() { super.onCreate(); mNotificationManager = (NotificationManager) this .getSystemService(NOTIFICATION_SERVICE); mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE); db = new TrackDb(this.getApplicationContext()); } @Override public void onStart(Intent intent, int startId) { super.onStart(intent, startId); } @Override public void onDestroy(){ //TODO super.onDestroy(); } @Override public IBinder onBind(Intent intent){ return this.mBinder; } private IBinder mBinder = new ITrackingServiceRemote.Stub() { public void startTracking(long trackId) throws RemoteException { TrackingService.this.startTracking(trackId); } public void pauseTracking() throws RemoteException { TrackingService.this.pauseTracking(); } public void resumeTracking(long trackId) throws RemoteException { TrackingService.this.resumeTracking(trackId); } public void stopTracking() throws RemoteException { TrackingService.this.stopTracking(); } public long trackingState() throws RemoteException { long state = TrackingService.this.trackingState(); return state; } }; public synchronized void startTracking(long trackId) { // request updates every 250 meters or 0 sec this.trackId = trackId; mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 250, this); isTracking = true; } public synchronized long trackingState() { if(isTracking){ return trackId; } else return -1; } public synchronized void stopTracking() { if(isTracking){ mLocationManager.removeUpdates(this); isTracking = false; } else Log.i(TAG, "Could not stop because service is not tracking at the moment"); } public synchronized void resumeTracking(long trackId) { if(!isTracking){ this.trackId = trackId; mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 250, this); isTracking = true; } else Log.i(TAG, "Could not resume because service is tracking already track " + this.trackId); } public synchronized void pauseTracking() { if(isTracking){ mLocationManager.removeUpdates(this); isTracking = false; } else Log.i(TAG, "Could not pause because service is not tracking at the moment"); } public void onLocationChanged(Location location) { //TODO } For easier access from the client I wrote a ServiceManager class which sets up the ServiceConnection and you can call the service methods. Here my code for this: public class TrackingServiceManager{ private static final String TAG = "TrackingServiceManager"; private ITrackingServiceRemote mService = null; private Context mContext; private Boolean isBound = false; private ServiceConnection mServiceConnection; public TrackingServiceManager(Context ctx){ this.mContext = ctx; } public void start(long trackId) { if (isBound && mService != null) { try { mService.startTracking(trackId); } catch (RemoteException e) { Log.e(TAG, "Could not start tracking!",e); } } else Log.i(TAG, "No Service bound! 1"); } public void stop(){ if (isBound && mService != null) { try { mService.stopTracking(); } catch (RemoteException e) { Log.e(TAG, "Could not stop tracking!",e); } } else Log.i(TAG, "No Service bound!"); } public void pause(){ if (isBound && mService != null) { try { mService.pauseTracking(); } catch (RemoteException e) { Log.e(TAG, "Could not pause tracking!",e); } } else Log.i(TAG, "No Service bound!"); } public void resume(long trackId){ if (isBound && mService != null) { try { mService.resumeTracking(trackId); } catch (RemoteException e) { Log.e(TAG, "Could not resume tracking!",e); } } else Log.i(TAG, "No Service bound!"); } public float state(){ if (isBound && mService != null) { try { return mService.trackingState(); } catch (RemoteException e) { Log.e(TAG, "Could not resume tracking!",e); return -1; } } else Log.i(TAG, "No Service bound!"); return -1; } /** * Method for binding the Service with client */ public boolean connectService(){ mServiceConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { TrackingServiceManager.this.mService = ITrackingServiceRemote.Stub.asInterface(service); } } @Override public void onServiceDisconnected(ComponentName name) { if (mService != null) { mService = null; } } }; Intent mIntent = new Intent("test.de.android.tracker.action.intent.TrackingService"); this.isBound = this.mContext.bindService(mIntent, mServiceConnection, Context.BIND_AUTO_CREATE); return this.isBound; } public void disconnectService(){ this.mContext.unbindService(mServiceConnection); this.isBound = false; } } If i now try to call a method from an activity for example start(trackId) nothing happens. The binding is OK. When debugging it always runs into the startTracking() in the generated ITrackingServiceRemote.java file and not into my TrackingService class. Where is the problem? I can't find anything wrong. Thanks in advance! Tobias

  • Exchange Web Service (EWS) call fails under ASP.NET but not a console application

    - by Vince Panuccio
    I'm getting an error when I attempt to connect to Exchange Web Services via ASP.NET. The following code works if I call it via a console application but the very same code fails when executed on a ASP.NET web forms page. Just as a side note, I am using my own credentials throughout this entire code sample. "When making a request as an account that does not have a mailbox, you must specify the mailbox primary SMTP address for any distinguished folder Ids." I thought I might be able to fix the issue by specifying an impersonated user. exchangeservice.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, "[email protected]"); But then I get a different error. "The account does not have permission to impersonate the requested user." The App Pool that the web application is running under is also my own account (same as the console application) so I have no idea what might be causing this issue. I am using .NET framework 3.5. Here is the code in full. var exchangeservice = new ExchangeService(ExchangeVersion.Exchange2010_SP1) { Timeout = 10000 }; var credentials = new System.Net.NetworkCredential("username", "pass", "domain"); exchangeservice.AutodiscoverUrl("[email protected]") FolderId rootFolderId = new FolderId(WellKnownFolderName.Inbox); var folderView = new FolderView(100) { Traversal = FolderTraversal.Shallow }; FindFoldersResults findFoldersResults = service.FindFolders(rootFolderId, folderView);

  • Named query not known error trying to call a stored proc using Fluent NHibernate

    - by Hamman359
    I'm working on setting up NHibernate for a project and I have a few queries that, due to their complexity, we will be leaving as stored procedures. I'd like to be able to use NHibernate to call the sprocs, but have run into an error I can't figure out. Since I'm using Fluent NHibernate I'm using mixed mode mapping as recommended here. However, when I run the app I get a "Named query not known: AccountsGetSingle" exception and I can't figure out why. I think I might have a problem with my HBM mapping since I'm not very familiar with using them but I'm not sure. My NHibernate configuration code is: private ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005 .ConnectionString((conn => conn.FromConnectionStringWithKey("CIDB"))) .ShowSql()) .Mappings(m => { m.HbmMappings.AddFromAssemblyOf<Account>(); m.FluentMappings.AddFromAssemblyOf<Account>(); }) .BuildSessionFactory(); } My hbm.xml file is: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <sql-query name="AccountsGetSingle"> <return alias="Account" class="Core, Account"></return> exec AccountsGetSingle </sql-query> </hibernate-mapping> And the code where I am calling the sproc looks like this: public Account Get() { return _conversation.Session .GetNamedQuery("AccountsGetSingle") .UniqueResult<Account>(); } Any thoughts or ideas would be appreciated. Thanks.

  • Using pinvoke in c# to call sprintf and friends on 64-bit

    - by bde
    I am having an interesting problem with using pinvoke in C# to call _snwprintf. It works for integer types, but not for floating point numbers. This is on 64-bit Windows, it works fine on 32-bit. My code is below, please keep in mind that this is a contrived example to show the behavior I am seeing. class Program { [DllImport("msvcrt.dll", CharSet = CharSet.Unicode, CallingConvention = CallingConvention.Cdecl)] private static extern int _snwprintf([MarshalAs(UnmanagedType.LPWStr)] StringBuilder str, uint length, String format, int p); [DllImport("msvcrt.dll", CharSet = CharSet.Unicode, CallingConvention = CallingConvention.Cdecl)] private static extern int _snwprintf([MarshalAs(UnmanagedType.LPWStr)] StringBuilder str, uint length, String format, double p); static void Main(string[] args) { Double d = 1.0f; Int32 i = 1; Object o = (object)d; StringBuilder str = new StringBuilder(); _snwprintf(str, 32, "%10.1f", (Double)o); Console.WriteLine(str.ToString()); o = (object)i; _snwprintf(str, 32, "%10d", (Int32)o); Console.WriteLine(str.ToString()); Console.ReadKey(); } } The output of this program is 0.0 1 It should print 1.0 on the first line and not 0.0, and so far I am stumped.

  • jQuery.ajax call to Twitter succeeds but returns null for Firefox

    - by Zhami
    I've got code that makes a simple get request to Twitter (search) using jQuery's ajax method. The code works fine on Safari, but fails on Firefox (3.6.3). In the Firefox case, my jQuery.ajax parameters 'success' method is invoked, but the supplied data is null. (In Safari, I receive a boatload of JSON data). My ajax call is: $.ajax({ url: 'http://search.twitter.com/search.json?q='+searchTerm, dataType: 'json', async: true, beforeSend: function(request) { window.console.log('starting AJAX request to get Twitter data'); }, success: function(data, textStatus, request) { window.console.log('AJAX request to get Twitter succeeded: status=' + textStatus); callback(data); }, error: function(request, status, error) { window.console.log('AJAX request to get user data --> Error: ' + status); errback(request, status, error); } }); Firebug shows Response headers: Date Sun, 11 Apr 2010 22:30:26 GMT Server hi Status 200 OK X-Served-From b021 X-Runtime 0.23841 Content-Type application/json; charset=utf-8 X-Served-By sjc1o024.prod.twitter.com X-Timeline-Cache-Hit Miss Cache-Control max-age=15, must-revalidate, max-age=300 Expires Sun, 11 Apr 2010 22:35:26 GMT Vary Accept-Encoding X-Varnish 1827846877 Age 0 Via 1.1 varnish X-Cache-Svr sjc1o024.prod.twitter.com X-Cache MISS Content-Encoding gzip Content-Length 2126 Connection close The HTTP status is OK (200), the Conetnt-Type is properly application/json, and the Content-Length of 2126 (gzip'd) implies data came back.

I am aware of a similar post on Stack Overflow: http://stackoverflow.com/questions/1188976/jquery-get-function-succeeds-with-200-but-returns-no-content-in-firefox and from that would assume this problem is possibly related to cross-domain security, but...

  • How to call SQL Function with multiple parameters from C# web page

    - by Marshall
    I have an MS SQL function that is called with the following syntax: SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = 7 AND LocationName = ''Default'' ', 10) The first parameter passes a specific WHERE clause that is used by the function for one of the internal queries. When I call this function in the front-end C# page, I need to send parameter values for the individual fields inside of the WHERE clause (in this example, both the ClientID & LocationName fields) The current C# code looks like this: String SQLText = "SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = @ClientID AND LocationName = @LocationName ',10)"; SqlCommand Cmd = new SqlCommand(SQLText, SqlConnection); Cmd.Parameters.Add("@ClientID", SqlDbType.Int).Value = 7; // Insert real ClientID Cmd.Parameters.Add("@LocationName", SqlDbType.NVarChar(20)).Value = "Default"; // Real code uses Location Name from user input SqlDataReader reader = Cmd.ExecuteReader(); When I do this, I get the following code from SQL profiler: exec sp_executesql N'SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationID nvarchar(20)', @ClientID=7,@LocationName=N'Default' When this executes, SQL throws an error that it cannot parse past the first mention of @ClientID stating that the Scalar Variable @ClientID must be defined. If I modify the code to declare the variables first (see below), then I receive an error at the second mention of @ClientID that the variable already exists. exec sp_executesql N'DECLARE @ClientID int; DECLARE @LocationName nvarchar(20); SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationName nvarchar(20)', @ClientID=7,@LocationName=N'Default' I know that this method of adding parameters and calling SQL code from C# works well when I am selecting data from tables, but I am not sure how to embed parameters inside of the ' quote marks for the embedded WHERE clause being passed to the function. Any ideas?

  • ASP.NET validation not executing in a JavaScript showModalDialog call

    - by Michael Kniskern
    I currently open a pop up window from my parent page using using a JavaScript .showModalDialog function. The pop up window contains some ASP.NET validation controls which do not display when the user clicks the ASP.NET button to submit the form. If there is an error on the page, the validation message(s) do not display, the record is not updated on the server side and the pop window closes. (The asp.net validation controls do not stop the pop up window from doing a server postback) Has anyone expereinced this behavior before and is there any way to prevent it? Here is my showModalDialong call source code: function OpenChildWindow(id) { var sFeatures = sFeatures="dialogHeight: 525px;"; sFeatures += "dialogWidth: 900px;"; sFeatures += "scroll: yes;"; sFeatures += "status: no;"; sFeatures += "resizeable: no;"; var url = "MyPopUp.aspx?ID=" + id; var childName = "ChildForm"; entryWindow = window.showModalDialog(url, childName, sFeatures); if (entryWindow == true) { window.document.getElementById("<%= btnUpdateParent.ClientID %>").click(); } } Note: When the pop up modal is closed, a ASP.NET button is "clicked" to update an ASP.NET UpdatePanel on the parent to show the changes to the record modified in the pop up window.

  • jquery ajax call from link loaded with ajax

The problem I'm having is some content loads with links which are intended to load content into a secondary window. I'm using the .live() method to allow jquery to listen for new links loaded into the primary content div. This works until the .ajax() method is called for these fresh links loaded with ajax, where the method begins, but follows the original link before data can be received. I'm assuming the problem is in the client-side scripting, but it may be a problem with the call made to the server. I'm using the wordpress loop to parse the url and generate the html loaded via jquery. Thanks for any tips!

  • WPF Dispatcher.UnhandledException within a ShowDialog call.

    - by Eric
    It appears that ShowDialog() invokes the Dispatcher message handling loop within. Thus, you have a stack that looks something like: Outer-most Dispatcher message loop ... x.ShowDialog() Inner Dispatcher message loop ... I am using the Dispatcher.UnhandledException to catch exceptions not handled by my code. However, it appears that the Inner Dispatcher message loop, above, is undesirably catching exceptions that my code would catch. Example: Outer-most Dispatcher message loop try/catch FooException ... x.ShowDialog() Inner Dispatcher message loop ... throw FooException What I would like is for the thrown FooException to get caught by the try/catch. However. It gets caught first by the (inner) Dispatcher.UnhandledException. I see there are ways to filter the exception. However, those filters will apply to both the inner and outer most handlers. What I am looking for is to have my Dispatcher.UnhandledException code run only on the outer-most dispatcher message loop. Does that make sense? I could, of course, reflect the call stack from within my handler to see if this is the outer-most dispatcher, but that seems a bit fragile. Other ideas? Thanks! Eric

  • NSCollectionView subclass doesn't call drawRect during drag session despite setNeedsDisplay

    - by Alain Vitry
    Greetings, I am puzzled as to how and when drawRect is supposed to be called in a NSCollectionView subclass. I implement drag and drop operation in order to move NSCollectionViewItems within the collection, and would like to draw a visual indication of where the drop would end. The subclass does not call drawRect during the drag session. (It does during scroll) Is this the intended operation ? Any hint on how to implement this behavior properly are welcome. A full xcode project of the following code is available at: http://babouk.ovh.org/dload/MyCollectionView.zip Best regards Code sample: @interface CollectionViewAppDelegate : NSObject <NSApplicationDelegate> { NSWindow *window; NSMutableArray *collectionContent; } /* properties declaration */ /* KVC compliance declarations */ @end @interface MyCollectionView : NSCollectionView @end @interface ItemModel { NSString *name; } @property (copy) NSString *name; @end @implementation MyCollectionView - (void)drawRect:(NSRect)rect { NSLog(@"DrawRect"); } - (void)mouseDragged:(NSEvent *)aEvent { NSPoint localPoint = [self convertPoint:[aEvent locationInWindow] fromView:nil]; [self dragImage:[NSImage imageNamed:@"Move.png"] at:localPoint offset:NSZeroSize event:aEvent pasteboard:nil source:self slideBack:NO]; } - (BOOL)prepareForDragOperation:(id < NSDraggingInfo >)sender { return YES; } - (NSDragOperation)draggingEntered:(id <NSDraggingInfo>)sender { return NSDragOperationEvery; } - (NSDragOperation)draggingUpdated:(id <NSDraggingInfo>)sender { [self setNeedsDisplay:YES]; return NSDragOperationEvery; } - (NSDragOperation)draggingSourceOperationMaskForLocal:(BOOL)isLocal { return NSDragOperationEvery; } - (void)mouseDown:(NSEvent *)theEvent { } @end @implementation CollectionViewAppDelegate @synthesize window, collectionContent, collectionView; - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { NSMutableArray *data = [[NSMutableArray alloc] init]; /* Fill in data */ [self setCollectionContent:data]; [data release]; } /* dealloc */ /* KVC implementation */ @end @implementation ItemModel @synthesize name; /* dealloc */ @end

    - by akenawell85x
    I recently decided to switch from Eclipse to Android Studio. I imported a project I was working on and am now getting this error when I try to run the project. Gradle: Execution failed for task ':project:dexDebug'. > Could not call IncrementalTask.taskAction() on task ':project:dexDebug' I've been cruising this site for 2 days now and trying different suggestions to no avail.

Any help would be greatly appreciated.

  • Call to undefined function query() - using PDO in PHP

    - by webworm
    I have a written a script in PHP that reads from data from a MySQL database. I am new to PHP and I have been using the PDO library. I have been developing on a Windows machine using the WAMP Server 2 and all has been working well. However, when I uploaded my script to the LINUX server where it will be used I get the following error when I run my script. Fatal error: Call to undefined function query() This is the line where the error is occuring ... foreach($dbconn->query($sql) as $row) The variable $dbconn is first defined in my dblogin.php include file which I am listing below. <?php // Login info for the database $db_hostname = 'localhost'; $db_database = 'MY_DATABASE_NAME'; $db_username = 'MY_DATABASE_USER'; $db_password = 'MY_DATABASE_PASSWORD'; $dsn = 'mysql:host=' . $db_hostname . ';dbname=' . $db_database . ';'; try { $dbconn = new PDO($dsn, $db_username, $db_password); $dbconn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { echo 'Error connecting to database: ' . $e->getMessage(); } ?> Inside the function where the error occurs I have the database connection defined as a superglobal as such ... global $dbconn; I am a bit confused as to what is happening since all worked well on my development machine. I was wondering if the PDO library was installed but from what I thought it was installed by default as part of PHP v5. The script is running on an Ubuntu (5.0.51a-3ubuntu5.4) machine and the PHP version is 5.2.4. Thank you for any suggestions. I am really lost on this.
