  • Link checker ; how to avoid false positives

    - by Burnzy
    I'm working a on a link checker/broken link finder and I am getting many false positives, after double checking I noticed that many error codes were returning webexceptions but they were actually downloadable, but in some other cases the statuscode is 404 and i can access the page from the browse. So here is the code, its pretty ugly, and id like to have something more, id say practical. All the status codes are in that big if are used to filter the ones i dont want to add to brokenlink because they are valid links ( i tested them all ). What i need to fix is the structure (if possible) and how to not get false 404. Thank you! try { HttpWebRequest request = ( HttpWebRequest ) WebRequest.Create ( uri ); request.Method = "Head"; request.MaximumResponseHeadersLength = 32; // FOR IE SLOW SPEED request.AllowAutoRedirect = true; using ( HttpWebResponse response = ( HttpWebResponse ) request.GetResponse() ) { request.Abort(); } /* WebClient wc = new WebClient(); wc.DownloadString( uri ); */ _validlinks.Add ( strUri ); } catch ( WebException wex ) { if ( !wex.Message.Contains ( "The remote name could not be resolved:" ) && wex.Status != WebExceptionStatus.ServerProtocolViolation ) { if ( wex.Status != WebExceptionStatus.Timeout ) { HttpStatusCode code = ( ( HttpWebResponse ) wex.Response ).StatusCode; if ( code != HttpStatusCode.OK && code != HttpStatusCode.BadRequest && code != HttpStatusCode.Accepted && code != HttpStatusCode.InternalServerError && code != HttpStatusCode.Forbidden && code != HttpStatusCode.Redirect && code != HttpStatusCode.Found ) { _brokenlinks.Add ( new Href ( new Uri ( strUri , UriKind.RelativeOrAbsolute ) , UrlType.External ) ); } else _validlinks.Add ( strUri ); } else _brokenlinks.Add ( new Href ( new Uri ( strUri , UriKind.RelativeOrAbsolute ) , UrlType.External ) ); } else _validlinks.Add ( strUri ); }

  • Checkbox in an email

    - by Austin
    I am creating an email using the c# MailMessage and I am trying to add a checkbox that doesn't need to be clicked. The checkboxes will be used for a checklist of what to bring to an event (like a packing list). I have: MailMessage objEmail = new MailMessage(); objEmail.From = new MailAddress("[email protected]"); objEmail.To.Add(new MailAddress("[email protected]")); objEmail.CC.Add(new MailAddress("[email protected]")); objEmail.Bcc.Add(new MailAddress("[email protected]")); objEmail.Subject = "Packing list!"; objEmail.IsBodyHtml = true; objEmail.Body = @"<div width=""800px""> <h3>WHAT TO BRING</h3> <form> <input type=""checkbox"" name=""item"" value=""shirt"">Shirt<br> <input type=""checkbox"" name=""item"" value=""shoes"">Shoes </form></div>"; but when I send the email the checkboxes do not appear in the list. Output in outlook using outlook.com: WHAT TO BRING I have a bike I have a car Output in outlook using Microsoft Outlook: WHAT TO BRING [ ]I have a bike [ ]I have a car Output in outlook using hotmail.com: WHAT TO BRING I have a bike []I have a car So the problem is with the mail client but it is inconsistent what the problem is. I s there any way to make a consistent output? Is there a way with html that works to create the checkboxes or do I just need to include images of a checkbox? Thanks in advance.

  • Can ASM method-visitors be used with interfaces?

    - by Olaf Mertens
    I need to write a tool that lists the classes that call methods of specified interfaces. It will be used as part of the build process of a large java application consisting of many modules. The goal is to automatically document the dependencies between certain java modules. I found several tools for dependency analysis, but they don't work on the method level, just for packages or jars. Finally I found ASM, that seems to do what I need. The following code prints the method dependencies of all class files in a given directory: import java.io.*; import java.util.*; import org.objectweb.asm.ClassReader; public class Test { public static void main(String[] args) throws Exception { File dir = new File(args[0]); List<File> classFiles = new LinkedList<File>(); findClassFiles(classFiles, dir); for (File classFile : classFiles) { InputStream input = new FileInputStream(classFile); new ClassReader(input).accept(new MyClassVisitor(), 0); input.close(); } } private static void findClassFiles(List<File> list, File dir) { for (File file : dir.listFiles()) { if (file.isDirectory()) { findClassFiles(list, file); } else if (file.getName().endsWith(".class")) { list.add(file); } } } } import org.objectweb.asm.MethodVisitor; import org.objectweb.asm.commons.EmptyVisitor; public class MyClassVisitor extends EmptyVisitor { private String className; @Override public void visit(int version, int access, String name, String signature, String superName, String[] interfaces) { this.className = name; } @Override public MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions) { System.out.println(className + "." + name); return new MyMethodVisitor(); } } import org.objectweb.asm.commons.EmptyVisitor; public class MyMethodVisitor extends EmptyVisitor { @Override public void visitMethodInsn(int opcode, String owner, String name, String desc) { String key = owner + "." + name; System.out.println(" " + key); } } The Problem: The code works for regular classes only! If the class file contains an interface, visitMethod is called, but not visitMethodInsn. I don't get any info about the callers of interface methods. Any ideas?

  • Rails show latest entry

    - by Danny McClelland
    Hi Everyone, I have a working Rails application on version 2.3.5 - I am using many to many model relations and have got almost everything working. What I would like to do is on my new kase page show the most recent kase job ref at the top. So for example, if I created a new kase with a job ref of "001", if I then went to create a new kase it would show at the top "Your previous kases reference was 001". I have the field of jobref in the new kase form, so I am trying to workout what I need to do to output only the last jobref. If that makes sense! Thanks, Danny

  • Qt drag & drop button; drop not detecting

  • UINavigationBar unresponsive after canceling a UITableView search in nav controller in tab bar in a popover

    - by Mark
    Ok, this is an odd one and I can reproduce it with a new project easily. Here is the setup: I have a UISplitViewController. In the left side I have a UITabBarController. In this tab bar controller I have two UINavigationControllers. In the navigation controllers I have UITableViewControllers. These table views have search bars on them. Ok, what happens with this setup is that if I'm in portrait mode and bring up this view in the popover and I start a search in one of the table views and cancel it, the navigation bar becomes unresponsive. That is, the "back" button as well as the right side button cannot be clicked. If I do the exact same thing in landscape mode so we are not in a popover, this doesn't happen. The navigation bar stays responsive. So, the problem only seems to happen inside a popover. I've also noticed that if I do the search but click on an item in the search results which ends up loading something into the "detail view" of the split view and dismissing the popover, and then come back to the popover and then click the Cancel button for the search, the navigation bar is responsive. My application is a universal app and uses the same tab bar controller in the iPhone interface and it works there without this issue. As I mentioned above, I can easily reproduce this with a new project. Here are the steps if you want to try it out yourself: start new project - split view create new UITableViewController class (i named TableViewController) uncomment out the viewDidLoad method as well as the rightBarButtonItem line in viewDidLoad (so we will have an Edit button in the navigation bar) enter any values you want to return from numberOfSectioinsInTableView and numberOfRowsInSection methods open MainWindow.xib and do the following: please note that you will need to be viewing the xib in the middle "view mode" so you can expand the contents of the items drag a Tab Bar Controller into the xib to replace the Navigation Controller item drag a Navigation Controller into the xib as another item under the Tab Bar Controller delete the other two view controllers that are under the Tab Bar Controller (so, now our tab bar has just the one navigation controller on it) inside the navigation controller, drag in a Table View Controller and use it to replace the View Controller (Root View Controller) change the class of the new Table View Controller to the class created above (TableViewController for me) double-click on the Table View under the new Table View Controller to open it up (will be displayed in the tab bar inside the split view controller) drag a "Search Bar and Search Display" onto the table view save the xib run the project in simulator while in portrait mode, click on the Root List button to bring up popover notice the Edit button is clickable click in the Search box - we go into search mode click the Cancel button to exit search mode notice the Edit button no longer works So, can anyone help me figure out why this is happening? Thanks, Mark

  • A linked list with multiple heads in Java

    - by Emile
    Hi, I have a list in which I'd like to keep several head pointers. I've tried to create multiple ListIterators on the same list but this forbid me to add new elements in my list... (see Concurrent Modification exception). I could create my own class but I'd rather use a built-in implementation ;) To be more specific, here is an inefficient implementation of two basic operations and the one wich doesn't work : class MyList <E { private int[] _heads; private List<E _l; public MyList ( int nbHeads ) { _heads = new int[nbHeads]; _l = new LinkedList<E(); } public void add ( E e ) { _l.add(e); } public E next ( int head ) { return _l.get(_heads[head++]); // ugly } } class MyList <E { private Vector<ListIterator<E _iters; private List<E _l; public MyList ( int nbHeads ) { _iters = new Vector<ListIterator<E(nbHeads); _l = new LinkedList<E(); for( ListIterator<E iter : _iters ) iter = _l.listIterator(); } public void add ( E e ) { _l.add(e); } public E next ( int head ) { // ConcurrentModificationException because of the add() return _iters.get(head).next(); } } Emile

  • Logging in with WebFinger and OpenID

    - by Ryan
    I would like to apologize in advance for the ugly formatting. In order to talk about the problem, I need to be posting a bunch of URLs, but the excessive URLs and my lack of reputation makes StackOverflow think I could be a spammer. Any instance of 'ht~tp' is supposed to be 'http'. '{dot}' is supposed to be '.' and '{colon}' is supposed to be ':'. Also, my lack of reputation has prevented me from tagging my question with 'webfinger' and 'google-profiles'. Onto my question: I am messing around with WebFinger and trying to create a small rails app that enables a user to log in using nothing but their WebFinger account. I can succesfully finger myself, and I get back an XRD file with the following snippet: Link rel="ht~tp://specs{dot}openid{dot}net/auth/2.0/provider" href="ht~tp://www{dot}google{dot}com/profiles/{redacted}"/ Which, to me, reads, "I have an OpenID 2.0 login at the url: ht~tp://www{dot}google{dot}com/profiles/{redacted}". But when I try to use that URL to log in, I get the following error OpenID::DiscoveryFailure (Failed to fetch identity URL ht~tp://www{dot}google{dot}com/profiles/{redacted} : Error encountered in redirect from ht~tp://www{dot}google{dot}com/profiles/{redacted}: Error fetching /profiles/{Redacted}: Connection refused - connect(2)): When I replace the profile URL with 'ht~tps://www{dot}google{dot}com/accounts/o8/id', the login works perfectly. here is the code that I am using (I'm using RedFinger as a plugin, and JanRain's ruby-openid, installed without the gem) require "openid" require 'openid/store/filesystem.rb' class SessionsController < ApplicationController def new @session = Session.new #render a textbox requesting a webfinger address, and a submit button end def create ####################### # # Pay Attention to this section right here # ####################### #use given webfinger address to retrieve openid login finger = Redfinger.finger(params[:session][:webfinger_address]) openid_url = finger.open_id.first.to_s #openid_url is now: ht~tp://www{dot}google{dot}com/profiles/{redacted} #Get needed info about the acquired OpenID login file_store = OpenID::Store::Filesystem.new("./noncedir/") consumer = OpenID::Consumer.new(session,file_store) response = consumer.begin(openid_url) #ERROR HAPPENS HERE #send user to OpenID login for verification redirect_to response.redirect_url('ht~tp://localhost{colon}3000/','ht~tp://localhost{colon}3000/sessions/complete') end def complete #interpret return parameters file_store = OpenID::Store::Filesystem.new("./noncedir/") consumer = OpenID::Consumer.new(session,file_store) response = consumer.complete params case response.status when OpenID::SUCCESS session[:openid] = response.identity_url #redirect somehwere here end end end Is it possible for me to use the URL I received from my WebFinger to log in with OpenID?

  • What are possible reasons for java.io.IOException: "The filename, directory name, or volume label sy

    - by Turismo
    I am trying to copy a file using the following code: File targetFile = new File(targetPath + File.separator + filename); ... targetFile.createNewFile(); fileInputStream = new FileInputStream(fileToCopy); fileOutputStream = new FileOutputStream(targetFile); byte[] buffer = new byte[64*1024]; int i = 0; while((i = fileInputStream.read(buffer)) != -1) { fileOutputStream.write(buffer, 0, i); } For some users the targetFile.createNewFile results in this exception: java.io.IOException: The filename, directory name, or volume label syntax is incorrect at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(File.java:850) Filename and directory name seem to be correct. The directory targetPath is even checked for existence before the copy code is executed and the filename looks like this: AB_timestamp.xml The user has write permissions to the targetPath and can copy the file without problems using the OS. As I don't have access to a machine this happens on yet and can't reproduce the problem on my own machine I turn to you for hints on the reason for this exception.

In the documentation I can find information about accessing Spreadsheets and how to "create/upload/copy" documents: http://code.google.com/apis/documents/overview.html Does anyone have a C# code example to do this in Silverlight, something like this: //PSEUDOCODE: WebClientGoogleDoc proxy = new WebClientGoogleDoc (); proxy.DownloadStringCompleted += new DownloadStringCompletedEventHandler(proxy_DownloadStringCompleted); proxy.DownloadProgressChanged += new DownloadProgressChangedEventHandler(proxy_DownloadProgressChanged); proxy.DownloadStringAsyncWithGoogleDocId("dc7gj86r_20dn2csqg3");

    - by PhOeNiX
    How can i validate a ComboBox for null entry? My combobox is in a model as i am generating it dynamically. Now what i want is that when the the columns are generated dynamically, the border of combobox should be red as no value is selected and once the value is selected the border shud become normal. The following is my combobox in model : DataGridTemplateColumn dataGridComboBoxTemplateColumnObj = new DataGridTemplateColumn(); dataGridComboBoxTemplateColumnObj.Header = column.Header; FrameworkElementFactory comboBoxFactory = new FrameworkElementFactory(typeof(ComboBox)); Binding bindingItemSourceObj = new Binding(column.ItemsSourcePropertyName); comboBoxFactory.SetValue(ComboBox.HorizontalAlignmentProperty, HorizontalAlignment.Stretch); comboBoxFactory.SetValue(ComboBox.ItemsSourceProperty, bindingItemSourceObj); comboBoxFactory.SetValue(ComboBox.SelectedValuePathProperty, column.ValuePropertyName); dataGridComboBoxTemplateColumnObj.CellTemplate = new DataTemplate(); dataGridComboBoxTemplateColumnObj.CellTemplate.VisualTree = comboBoxFactory;

  • using the ASP.NET Caching API via method annotations in C#

    - by craigmoliver
    In C#, is it possible to decorate a method with an annotation to populate the cache object with the return value of the method? Currently I'm using the following class to cache data objects: public class SiteCache { // 7 days + 6 hours (offset to avoid repeats peak time) private const int KeepForHours = 174; public static void Set(string cacheKey, Object o) { if (o != null) HttpContext.Current.Cache.Insert(cacheKey, o, null, DateTime.Now.AddHours(KeepForHours), TimeSpan.Zero); } public static object Get(string cacheKey) { return HttpContext.Current.Cache[cacheKey]; } public static void Clear(string sKey) { HttpContext.Current.Cache.Remove(sKey); } public static void Clear() { foreach (DictionaryEntry item in HttpContext.Current.Cache) { Clear(item.Key.ToString()); } } } In methods I want to cache I do this: [DataObjectMethod(DataObjectMethodType.Select)] public static SiteSettingsInfo SiteSettings_SelectOne_Name(string Name) { var ck = string.Format("SiteSettings_SelectOne_Name-Name_{0}-", Name.ToLower()); var dt = (DataTable)SiteCache.Get(ck); if (dt == null) { dt = new DataTable(); dt.Load(ModelProvider.SiteSettings_SelectOne_Name(Name)); SiteCache.Set(ck, dt); } var info = new SiteSettingsInfo(); foreach (DataRowView dr in dt.DefaultView) info = SiteSettingsInfo_Load(dr); return info; } Is it possible to separate those concerns like so: (notice the new annotation) [CacheReturnValue] [DataObjectMethod(DataObjectMethodType.Select)] public static SiteSettingsInfo SiteSettings_SelectOne_Name(string Name) { var dt = new DataTable(); dt.Load(ModelProvider.SiteSettings_SelectOne_Name(Name)); var info = new SiteSettingsInfo(); foreach (DataRowView dr in dt.DefaultView) info = SiteSettingsInfo_Load(dr); return info; }

  • How to get size of bytes?

    - by k80sg
    How do I obtain the number of bytes before allocating the byte size of the array 'handsize' as shown below as the incoming ByteArray data are sent in 3 different sizes. Thanks. BufferedInputStream bais = new BufferedInputStream(requestSocket.getInputStream()); DataInputStream datainput = new DataInputStream(bais); //need to read the number of bytes here before proceeding. byte[] handsize = new byte[bytesize]; datainput.readFully(handsize);

  • JPanel.addComponentListener does not work when the listener is a class variable

    - by Coder
    I have a public class which has the following method and instance variable: public void setImagePanel(JPanel value) { imagePanel = value; if (imagePanel != null) { //method 1 : works imagePanel.addComponentListener(new ComponentAdapter() { public void componentResized(ComponentEvent evt) { System.out.println("Here 1"); } }); //method 2 : does not work panelResizeListener = new ResizeListener(); imagePanel.addComponentListener(panelResizeListener); //method 3 : works //ResizeListener listener = new ResizeListener(); //imagePanel.addComponentListener(listener); //method 4 : works //imagePanel.addComponentListener(new ResizeListener()); //method 5 : does not work -- THIS IS THE DESIRED CODE I WANT TO USE imagePanel.addComponentListener(panelResizeListener); } } public class ResizeListener extends ComponentAdapter { @Override public void componentResized(ComponentEvent evt) { System.out.println("RESIZE 3"); } } private ResizeListener panelResizeListener = new ResizeListener(); Each of the methods above correspond the to code immediately below until the next //method comment. What i don't understand is why i can't use the class instance variable and add that to the JPanel as a component listener. What happens in the cases above where i say that the method does not work is that i don't get the "RESIZE 3" log messages. In all cases where i list that it works, then i get the "RESIZE 3" messages. The outer class is public with no other modification except that it implements an interface that i created (which has no methods or variables in common with the methods and variables listed above). If anyone can help me i would greatly appreciate it. This problem makes no sense to me, the code should be identical.

  • HttpClient response handler always returns closed stream

    - by Alex Ciminian
    I'm new to Java development so please bear with me. Also, I hope I'm not the champion of tl;dr :). I'm using HttpClient to make requests over Http (duh!) and I'd gotten it to work for a simple servlet that receives an URL as a query string parameter. I realized that my code could use some refactoring, so I decided to make my own HttpResponseHandler, to clean up the code, make it reusable and improve exception handling. I currently have something like this: public class HttpResponseHandler implements ResponseHandler<InputStream>{ public InputStream handleResponse(HttpResponse response) throws ClientProtocolException, IOException { int statusCode = response.getStatusLine().getStatusCode(); InputStream in = null; if (statusCode != HttpStatus.SC_OK) { throw new HttpResponseException(statusCode, null); } else { HttpEntity entity = response.getEntity(); if (entity != null) { in = entity.getContent(); // This works // for (int i;(i = in.read()) >= 0;) System.out.print((char)i); } } return in; } } And in the method where I make the actual request: HttpClient httpclient = new DefaultHttpClient(); HttpGet httpget = new HttpGet(target); ResponseHandler<InputStream> httpResponseHandler = new HttpResponseHandler(); try { InputStream in = httpclient.execute(httpget, httpResponseHandler); // This doesn't work // for (int i;(i = in.read()) >= 0;) System.out.print((char)i); return in; } catch (HttpResponseException e) { throw new HttpResponseException(e.getStatusCode(), null); } The problem is that the input stream returned from the handler is closed. I don't have any idea why, but I've checked it with the prints in my code (and no, I haven't used them both at the same time :). While the first print works, the other one gives a closed stream error. I need InputStreams, because all my other methods expect an InputStream and not a String. Also, I want to be able to retrieve images (or maybe other types of files), not just text files. I can work around this pretty easily by giving up on the response handler (I have a working implementation that doesn't use it), but I'm pretty curious about the following: Why does it do what it does? How do I open the stream, if something closes it? What's the right way to do this, anyway :)? I've checked the docs and I couldn't find anything useful regarding this issue. To save you a bit of Googling, here's the Javadoc and here's the HttpClient tutorial (Section 1.1.8 - Response handlers). Thanks, Alex
