  • Scanner's Read Line returning NoSuchElementException

    - by Brian
    This is my first time using StackOverflow. I am trying to read a text file which consists of a single number one the first line. try { Scanner s = new Scanner(new File("HighScores.txt")); int temp =Integer.parseInt(s.nextLine()); s.close(); return temp; } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } However, I get an error: java.util.NoSuchElementException: No line found at java.util.Scanner.nextLine(Unknown Source) at GameStart.getHighScore(GameStart.java:334) at GameStart.init(GameStart.java:82) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source) I know that HighScores.txt is not empty, so why is this problem occuring? I tried using BufferedReader, and BufferReader.readLine() return null.

  • JQUERY common function library create script errors. How to avoid?

    - by Cesar Lopez
    Hi all, I am building a common function library but the functions inside need to reference different jquery files, which they may need to be referenced in some pages but not in others. When I called this common function library in one web page which is only going to use one function, and I don't reference the files need it for the other function, then it will create a script error. My question is if it would be possible to stop this script errors like... //This if statement is what I was thinking to stop going through if ($(".objectdate") != null){ //This is the function that is calling other jquery files and creates error. $(document).ready(function() { $(".objectdate").datepicker({ //Code inside. }); }); } Thanks.

  • C# Creating thumbnail (low quality and big size problem)

    - by ile
    public void CreateThumbnail(Image img1, Photo photo, string targetDirectoryThumbs) { int newWidth = 700; int newHeight = 700; double ratio = 0; if (img1.Width > img1.Height) { ratio = img1.Width / (double)img1.Height; newHeight = (int)(newHeight / ratio); } else { ratio = img1.Height / (double)img1.Width; newWidth = (int)(newWidth / ratio); } Image bmp1 = img1.GetThumbnailImage(newWidth, newHeight, null, IntPtr.Zero); bmp1.Save(targetDirectoryThumbs + photo.PhotoID + ".jpg"); img1.Dispose(); bmp1.Dispose(); } I've put 700px so that you can have better insight of the problem. Here is original image and resized one. Any good recommendation? Thanks, Ile

  • How do I build a python string from a raw (binary) ctype buffer?

    - by fcrazy
    I'm playing with Python and ctypes and I can't figure out how to resolve this problem. I call to a C function which fills a raw binary data. My code looks like this: class Client(): def __init__(self): self.__BUFSIZE = 1024*1024 self.__buf = ctypes.create_string_buffer(self.__BUFSIZE) self.client = ctypes.cdll.LoadLibrary(r"I:\bin\client.dll") def do_something(self): len_written = self.client.fill_raw_buffer(self.__buf, self.__BUFSIZE) my_string = repr(self.__buf.value) print my_string The problem is that I'm receiving binary data (with 0x00) and it's truncated when I tried to build my_string. How can I build my_string if self._buf contains null bytes 0x00? Any idea is welcome. Thanks

  • Multithreaded Win32 GUI message loop

    When do you need to use this type of modified message loop in multithreaded application? DWORD nWaitCount; HANDLE hWaitArray[4]; BOOL quit; int exitCode; while (!quit) { MSG msg; int rc; rc = MsgWaitForMultipleObjects(nWaitCount, hWaitArray, FALSE, INFINITE,QS_ALLINPUT); if (rc == WAIT_OBJECT_O + nWaitCount) { while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) { if (msg.message == WM_QUIT) { quit = TRUE; exitCode = msg.wParam; break; } TranslateMessage(&msg); DispatchMessage(&msg); } } else if (rc >= WAIT_OBJECT_0 && rc < WAIT_OBJECT_0 + nwaitCount) { int nlndex = rc - WAIT_OBJECT_0; } else if (rc >= WAIT_ABANDONED_0 && rc < WAIT_ABANDONED_0+ nWaitCount) { int nlndex = rc - WAIT_ABANDONED_O; } }

  • Custom validatior in ASP.net

    - by DJPB
    Hi there. I'm working on an ASP.NET/C# app. I have 2 text boxes and I need to validate if the input text for both of them are not both null ex: if(string.IsNullOrEmpty(TextBox1.Text) && string.IsNullOrEmpty(TextBox2.Text) ) //FAIL!!! else // OK! that is, at least one txtBox has values I was planning on using a custom validator but it seems that the validation function only gets called when something is written on the textBox i'm using has the 'control to validate'. Now, that doesn't work for me since I want to show an error message when both text boxes are empty. Is there a way to make the validation function to be called with, for example a postback? Or is there any other better approach to this case than the custom validator? tks

  • Freeing Java memory at a specific point in time

    - by Marcus
    Given this code, where we load a lot of data, write it to a file, and then run an exe.. void myMethod() { Map stuff = createMap(); //Consumes 250 MB memory File file = createFileInput(stuff); //Create input for exe runExectuable(file); //Run Windows exe } What is the best way to release the memory consumed by stuff prior to running the exe? We don't need this in memory any more as we have dumped the data to a file for input to the exe... Is the best method to just set stuff = null prior to runExecutable(file)?

  • Entity Framework (4.0) how to exclude a related table.

    - by Kohan
    I have just updated to using EF 4.0 where before i was using Linq 2 SQL. I have a query: var UserList = this.repository.GetUsers(); return Json(UserList, JsonRequestBehavior.AllowGet); This was generating an error: "A circular reference was detected while serializing an object of type" This prompted this code which worked fine in L2S: var UserList = this.repository.GetUsers(); foreach (User u in UserList){ u.Subscriptions = null; } return Json(UserList, JsonRequestBehavior.AllowGet); How can i stop EF from looking into the Subscriptions table, i just want the Userlist, none of the related properties and the above example does not seem to work for this. Cheers, Kohan

  • using NEWSEQUENTIALID() with UPDATE Trigger

    - by Ram
    I am adding a new GUID/Uniqueidentifier column to my table. ALTER TABLE table_name ADD VersionNumber UNIQUEIDENTIFIER UNIQUE NOT NULL DEFAULT NEWSEQUENTIALID() GO And when ever a record is updated in the table, I would want to update this column "VersionNumber". So I create a new trigger CREATE TRIGGER [DBO].[TR_TABLE_NAMWE] ON [DBO].[TABLE_NAME] AFTER UPDATE AS BEGIN UPDATE TABLE_NAME SET VERSIONNUMBER=NEWSEQUENTIALID() FROM TABLE_NAME D JOIN INSERTED I ON D.ID=I.ID/* some ID which is used to join*/ END GO But just realized that NEWSEQUENTIALID() can only be used with CREATE TABLE or ALTER TABLE. I got this error The newsequentialid() built-in function can only be used in a DEFAULT expression for a column of type 'uniqueidentifier' in a CREATE TABLE or ALTER TABLE statement. It cannot be combined with other operators to form a complex scalar expression. Is there a workaround for this ? Edit1: Changing NEWSEQUENTIALID() to NEWID() in the trigger solves this, but I am indexing this column and using NEWID() would be sub-optimal

  • Case insensitive expectations in Rhino Mocks

    - by user313886
    I'm using Rhino Mocks to expect a call. There is a single parameter which is a string. But I'm not bothered about the case of the string. I want the test to pass even if the case is wrong. So I'm doing the following: //expect log message to be called with a string parameter. //We want to ignore case when verifiyig so we use a constraint instead of a direct parameter Expect.Call(delegate { logger.LogMessage(null); }).Constraints(Is.Matching<string>(x => x.ToLower()=="f2")); It seems a bit log winded. Is there a more sensible way of doing this?

  • Need to get to the foreign keys of an entity marked as "Deleted" for auditing

    - by Abhijeet Patel
    I'm using v1 of EF(.NET 3.5 SP1). I'm subscribing to the SavingChanges event of the ObjectContext wherein I audit deletes for a particular entity type. I need to get to the foreign keys of the entity being deleted i.e EntityKeys of the related entities (RelatedEnds) but the EntityKeys of the related entities are nulls. Is there any way to get to the foreign keys of an entity which has been marked for deletion? Does EF null out the EntityKeys of all RelatedEnds for an entity which has been marked for deletion? If so, is there a way I can get hold of the foreign keys?

  • sqlite & python - only pulls the first result

    - by pencilNero
    This is pretty strange (admitedly, this is my first attempt with python / sqlite), but I can seem to get all of the rows if I do a fetchAll(), but other than that - no matter what I try, always ends up in the db only returning the first row - the second iteration stops because a null is returned. Wondering if there is something wrong with how I am coding this up in python? The db seems ok.. con = sqlite3.connect('backup.db') con.row_factory = sqlite3.Row cur = con.cursor() cur.execute('select * from tb1;') for row in cur: try: # row = dataCur.fetchone() #if row == None: break print type(row) print ' Starting on: %i' % row[0] cleaner = Cleaner(scripts=True, remove_tags=['img'], embedded=True) try: cleaned = cleaner.clean_html(row[2]) #data stored in second col cur.execute('update tb1 set data = ? where id = ?;', (cleaned, row[0])) except AttributeError: print 'Attribute error' print ' Ended on: %i' % row[0] except IOError: print 'IOexception'

  • How to detect if a form input element of type file is empty

    I have some code which reads a file through a form field of type file <input type="file" ... /> I want to give the user another option of providing a url to a file rather than having to upload it as many are already online.

  • 42000 Syntax error in query when executing prepared statement

  • .NET 3.5 SP1 Code from Network - "The system cannot find the file specified."

    - by DaMoose
    This issue has nothing to do with whether the assemblies have been signed or caspol has been run for the shared network folder. Apparently, the location of the files is the issue, but I cannot find what the real problem is. I have one executable that references 5 dll's. I can run the app from a local drive without any problem. When I run the app from a network share, I get an error stating that "Could not load file or assembly 'homer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." If all the files are in the same folder, what is the error really telling me? I should note also that the framework used is 3.5 SP1, which does not require changing code access policy. I had tried that anyhow, and I received the same error in both cases. Thanks, DaMoose

  • Is an object still connected to a list after FirstOrDefault?

    - by Cynthia
    Here's my code: Event thisEvent = (from i in list where (i.eventID == eventID) select i).FirstOrDefault(); if (thisEvent != null) { thisEvent.eventResolved = resolved; thisEvent.eventSequence.Add(item); } "list" is a collection of IEnumerable, i.e. IEnumerable<Event> list; What I'm wondering is: after creating thisEvent using FirstOrDefault, is thisEvent still connected to list? In other words, when I change the two properties, eventResolved and eventSequence, is "list" actually changed, or is thisEvent just some totally disconnected copy of an item in "list"?

  • Problem mapping data located in a NSMutableArray

    - by Graeme
    I have an NSMutableArray which contains some addresses which I need to map using Apple's MapKit SDK which I can't seem to get to load. The NSLog keeps telling me that the data source is (null) and a 0x0 error displays when I attempt to print out the array. Any ideas? The data is parsed and stored from another class, perhaps I'm not linking it across properly? The data is originally gathered from an RSS feed, bought into the app with an IMporter class, and then displayed in a table view. I want to be able to connect into that data with my mapping class, but am struggling to do so.

  • how to create resources without VS C++ 2008 creating MFC files

    - by numerical25
    I am creating a WIN32 application and I want most of all my application events to be made through the message queue. But everytime I create a dialog box or any resource like that. The IDE auto generates code that I don't necessarily need. I believe it's MFC code not sure. here it is. // dlgChangeDevice.cpp : implementation file // #include "stdafx.h" #include "ZFXD3D.h" #include "dlgChangeDevice.h" // dlgChangeDevice dialog IMPLEMENT_DYNAMIC(dlgChangeDevice, CDialog) dlgChangeDevice::dlgChangeDevice(CWnd* pParent /*=NULL*/) : CDialog(dlgChangeDevice::IDD, pParent) { } dlgChangeDevice::~dlgChangeDevice() { } void dlgChangeDevice::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); } BEGIN_MESSAGE_MAP(dlgChangeDevice, CDialog) ON_CBN_SELCHANGE(IDC_COMBO5, &dlgChangeDevice::OnCbnSelchangeCombo5) END_MESSAGE_MAP() // dlgChangeDevice message handlers void dlgChangeDevice::OnCbnSelchangeCombo5() { // TODO: Add your control notification handler code here } Not sure what it is but I don't need it. I want to retrieve all my code through the dialog message queue. So what should I do ?? Just disregard it and delete it. Will a hurt anything by doing so ??
