  • Calling webservice via server causes java.net.MalformedURLException: no protocol

    - by Thomas
    I am writing a web-service, which parses an xml file. In the client, I read the whole content of the xml into a String then I give it to the web-service. If I run my web-service with main as a Java-Application (for tests) there is no problem, no error messages. However when I try to call it via the server, I get the following error: java.net.MalformedURLException: no protocol I use the same xml file, the same code (without main), and I just cannot figure out, what the cause of the error can be. here is my code: DOMParser parser=new DOMParser(); try { parser.setFeature("http://xml.org/sax/features/validation", true); parser.setFeature("http://apache.org/xml/features/validation/schema",true); parser.setFeature("http://apache.org/xml/features/validation/dynamic",true); parser.setErrorHandler(new myErrorHandler()); parser.parse(new InputSource(new StringReader(xmlFile))); document=parser.getDocument(); xmlFile is constructed in the client so: String myFile ="C:/test.xml"; File file=new File(myFile); String myString=""; FileInputStream fis=new FileInputStream(file); BufferedInputStream bis=new BufferedInputStream(fis); DataInputStream dis=new DataInputStream(bis); while (dis.available()!=0) { myString=myString+dis.readLine(); } fis.close(); bis.close(); dis.close(); Any suggestions will be appreciated!

  • How do I find a source code position from an address given by a crash in Window CE

    - by Shane MacLaughlin
    I have a Windows mobile 4.0 application, written using EVC++ 4.0 SP4 with MFC, that is exhibiting a random occasional crash in the field. e.g. Exception ox800000002 at 00112584. It does not happen under various emulators and simulators, hence is very difficult to trace using a debugger. The crash throws up and address and exception type. Given that I have the PDB is there any way to track this address to the source. I can't recompile using VC++ 8 as it doesn't support the mobile 4 SDK. My guess is that without a stack trace I'm not going to have much joy, as the chances are that the exception may not be in my source. Worth a try all the same. Edit As suggested, I have looked at the address in the context of the .MAP file for the program. This reveals the following Address Publics by Value Rva+Base Lib:Object 0001:00000000 ?GetUnduValue@@YANMM@Z 00011000 f 7Par.obj ' ' ' 0001:001124b8 ?OnLButtonUp@CGXGridUserDragSelectRangeImp@@UAAHPAVCGXGridCore@@AAVCPoint@@AAI@Z 001234b8 f gxseldrg.obj 0001:001126d8 ?OnSelDragStart@CGXGridUserDragSelectRangeImp@@UAAHPAVCGXGridCore@@KK@Z 001236d8 f gxseldrg.obj Which suggests the error occured during CGXGridUserDragSelectRangeImp::OnLButtonUp(), which seems a bit odd as I don't think there was a mouse / keyboard / screen button pressed at the time. Could be the stack got fragged before the crash got reported, and I'm wasting my time. I'll recompile with assembler output to try to isolate it to a given line, but don't hold out much hope :( Does the fact that the map file reports segmented addresses e.g. 0001:xxxxxxxxx and the crash report unsegmented addresses mean I have to carry out some computation to get the map address from the crash address?

  • Syncing data between devel/live databases in Django

    - by T. Stone
    With Django's new multi-db functionality in the development version, I've been trying to work on creating a management command that let's me synchronize the data from the live site down to a developer machine for extended testing. (Having actual data, particularly user-entered data, allows me to test a broader range of inputs.) Right now I've got a "mostly" working command. It can sync "simple" model data but the problem I'm having is that it ignores ManyToMany fields which I don't see any reason for it do so. Anyone have any ideas of either how to fix that or a better want to handle this? Should I be exporting that first query to a fixture first and then re-importing it? from django.core.management.base import LabelCommand from django.db.utils import IntegrityError from django.db import models from django.conf import settings LIVE_DATABASE_KEY = 'live' class Command(LabelCommand): help = ("Synchronizes the data between the local machine and the live server") args = "APP_NAME" label = 'application name' requires_model_validation = False can_import_settings = True def handle_label(self, label, **options): # Make sure we're running the command on a developer machine and that we've got the right settings db_settings = getattr(settings, 'DATABASES', {}) if not LIVE_DATABASE_KEY in db_settings: print 'Could not find "%s" in database settings.' % LIVE_DATABASE_KEY return if db_settings.get('default') == db_settings.get(LIVE_DATABASE_KEY): print 'Data cannot synchronize with self. This command must be run on a non-production server.' return # Fetch all models for the given app try: app = models.get_app(label) app_models = models.get_models(app) except: print "The app '%s' could not be found or models could not be loaded for it." % label for model in app_models: print 'Syncing %s.%s ...' % (model._meta.app_label, model._meta.object_name) # Query each model from the live site qs = model.objects.all().using(LIVE_DATABASE_KEY) # ...and save it to the local database for record in qs: try: record.save(using='default') except IntegrityError: # Skip as the record probably already exists pass

  • How to move/drag multiple images with CALayer???

    - by gbf.sara
    I have more than 10 images in screen and i want to move each image using CALayer concept. While am trying to move first image,its working. Even when i drag my second image also, its working. But after that when i get back to first image and when i try to move , am struck up. its not working. I dono where it went wrong. Here's ma code //Assigning Layer to UIImage// layer = [CALayer layer]; UIImage *image1 = [UIImage imageNamed:[NSString stringWithFormat:@"%@_thumb.png",[tiv imageName]]]; layer.contents = (id)image1.CGImage; layer.position=CGPointMake(200,200); layer.frame = CGRectMake(110, 180, 100, 100); [self.view.layer addSublayer:layer]; [layer needsDisplay]; [self.view.layer needsDisplay]; [layer needsLayout]; //Here i try to move my image// - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesMoved:touches withEvent:event]; NSArray *allTouches = [touches allObjects]; int count = [allTouches count]; if (count == 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:0] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } if (count > 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:-1] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } } Also ive planned to use single CALayer for multiple images.. When i click an image, it should be placed in that CALayer and when i click another, the same CALayer should take the latter one. So tat whenever i drag an image it should move(no matter how many images r there) . Do u think this concept will work out or is there any other idea??? My concept may seems to be a basic one. Am new to this environment n so kindly help me..

  • Avoiding shutdown hook

    Through the following code I can play and cut and audio file. Is there any other way to avoid using a shutdown hook? The problem is that whenever I push the cut button , the file doesn't get saved until I close the application thanks ...................... void play_cut() { try { // First, we get the format of the input file final AudioFileFormat.Type fileType = AudioSystem.getAudioFileFormat(inputAudio).getType(); // Then, we get a clip for playing the audio. c = AudioSystem.getClip(); // We get a stream for playing the input file.

Runtime.getRuntime().addShutdownHook(new Thread() { public void run() { // We're now in the hook, which means the program is shutting down. // You would need to use better exception handling in a production application. try { // Stop the audio clip. c.stop(); // Create a new input stream, with the duration set to the frame count we reached.

  • How to synchronize placing an object in JNDI across processes?

    - by indra
    I am trying to place an object in JNDI, so that only one of the progam should be able to place it in JNDI. is there any global lock that can be used in J2EE environment. Is RMI can be used for this purpose? please provide any reference links. Thanks in advance. Also, what is NameAlreadyBoundexception? I am trying to use it as a method to synchronize, i.e, only one program places it in JNDI and if other trying to bind should get that exception. But when i am testing the multiple binding I am not getting the Exception.And second binding is done. look up is giving the second object bound. here is my code: private static String JNDI_NAME = "java:comp/env/test/something"; public class TestJNDI { private static String JNDI_NAME = "java:comp/env/test/something"; public static void main(String[] args) throws NamingException { Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); env.put(Context.PROVIDER_URL,"t3://127.0.0.1:7001"); Context ctx = new InitialContext(env); System.out.println("Initial Context created"); String obj1 = "obj1"; String obj2 = "obj2"; try{ ctx.bind(JNDI_NAME, obj1); System.out.println("Bind Sucess"); }catch(NameAlreadyBoundException ne ){ // already bound System.out.println("Name already bound"); } ctx.close(); Context ctx2 = new InitialContext(env); try{ // Second binding to the same name not giving the Exception?? ctx2.bind(JNDI_NAME, obj2); System.out.println("Re Bind Sucess"); }catch(NameAlreadyBoundException ne ){ // already bound System.out.println("Name already bound"); } String lookedUp = (String) ctx2.lookup(JNDI_NAME); System.out.println("LookedUp Object"+lookedUp); ctx2.close(); } }

  • Performance Difference between HttpContext user and Thread user

    - by atrueresistance
    I am wondering what the difference between HttpContext.Current.User.Identity.Name.ToString.ToLower and Thread.CurrentPrincipal.Identity.Name.ToString.ToLower. Both methods grab the username in my asp.net 3.5 web service. I decided to figure out if there was any difference in performance using a little program. Running from full Stop to Start Debugging in every run. Dim st As DateTime = DateAndTime.Now Try 'user = HttpContext.Current.User.Identity.Name.ToString.ToLower user = Thread.CurrentPrincipal.Identity.Name.ToString.ToLower Dim dif As TimeSpan = Now.Subtract(st) Dim break As String = "nothing" Catch ex As Exception user = "Undefined" End Try I set a breakpoint on break to read the value of dif. The results were the same for both methods. dif.Milliseconds 0 Integer dif.Ticks 0 Long Using a longer duration, loop 5,000 times results in these figures. Thread Method run 1 dif.Milliseconds 125 Integer dif.Ticks 1250000 Long run 2 dif.Milliseconds 0 Integer dif.Ticks 0 Long run 3 dif.Milliseconds 0 Integer dif.Ticks 0 Long HttpContext Method run 1 dif.Milliseconds 15 Integer dif.Ticks 156250 Long run 2 dif.Milliseconds 156 Integer dif.Ticks 1562500 Long run 3 dif.Milliseconds 0 Integer dif.Ticks 0 Long So I guess what is more prefered, or more compliant with webservice standards? If there is some type of a performance advantage, I can't really tell. Which one scales to larger environments easier?

  • Can a class inherit from LambdaExpression in .NET? Or is this not recommended?

    - by d.
    Consider the following code (C# 4.0): public class Foo : LambdaExpression { } This throws the following design-time error: Foo does not implement inherited abstract member System.Linq.Expressions.LambdaExpression.Accept(System.Linq.Expressions.Compiler.StackSpiller) There's absolutely no problem with public class Foo : Expression { } but, out of curiosity and for the sake of learning, I've searched in Google System.Linq.Expressions.LambdaExpression.Accept(System.Linq.Expressions.Compiler.StackSpiller) and guess what: zero results returned (when was the last time you saw that?). Needless to say, I haven't found any documentation on this method anywhere else. As I said, one can easily inherit from Expression; on the other hand LambdaExpression, while not marked as sealed (Expression<TDelegate> inherits from it), seems to be designed to prevent inheriting from it. Is this actually the case? Does anyone out there know what this method is about? EDIT (1): More info based on the first answers - If you try to implement Accept, the editor (C# 2010 Express) automatically gives you the following stub: protected override Expression Accept(System.Linq.Expressions.ExpressionVisitor visitor) { return base.Accept(visitor); } But you still get the same error. If you try to use a parameter of type StackSpiller directly, the compiler throws a different error: System.Linq.Expressions.Compiler.StackSpiller is inaccessible due to its protection level. EDIT (2): Based on other answers, inheriting from LambdaExpression is not possible so the question as to whether or not it is recommended becomes irrelevant. I wonder if, in cases like this, the error message should be Foo cannot implement inherited abstract member System.Linq.Expressions.LambdaExpression.Accept(System.Linq.Expressions.Compiler.StackSpiller) because [reasons go here]; the current error message (as some answers prove) seems to tell me that all I need to do is implement Accept (which I can't do).

  • call lynx from jsp script

    - by Piero
    Hi, I have an execute(String cmd) in a jsp script that calls the exec method from the Runtime class. It works when I call a local command, like a php script stored on the server. for example: /usr/bin/php /path/to/php/script arg1 arg2 So I guess my execute command is ok, since it is working with that. Now when I try to call lynx, the text-based web browser, it does not work. If I call it in a terminal, it works fine: /usr/bin/lynx -dump -accept_all_cookies 'http://www.someurl.net/?arg1=1&arg2=2' But when I call this from my execute command, nothing happens... Any idea why? This is my execute method: public String execute(String cmd){ Runtime r = Runtime.getRuntime(); Process p = null; String res = ""; try { p = r.exec(cmd); InputStreamReader isr = new InputStreamReader(p.getInputStream()); BufferedReader br = new BufferedReader(isr); String line = null; //out.println(res); while ((line = br.readLine()) != null) { res += line; } p.waitFor(); } catch (Exception e) { res += e; } System.out.println(p.exitValue()); return res; }

  • Flex 3 Close UrlLoader throws exception

    - by gmoniey
    I am trying to simulate a 'HEAD' method using UrlLoader; essentially, I just want to check for the presence of a file without downloading the entire thing. I figured I would just use HttpStatusEvent, but the following code throws an exception (one that I can't wrap in a try/catch block) when you run in debug mode. <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="init()"> <mx:Script> <![CDATA[ private static const BIG_FILE:String = "http://www.archive.org/download/gspmovvideotestIMG0021mov/IMG_0021.mov"; private var _loader:URLLoader; private function init():void { _loader = new URLLoader(); _loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, statusHandler); _loader.addEventListener(IOErrorEvent.IO_ERROR, errorHandler); _loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, errorHandler); _loader.load(new URLRequest(BIG_FILE)); } public function unload():void { try { _loader.close(); _loader.removeEventListener(HTTPStatusEvent.HTTP_STATUS, statusHandler); _loader.removeEventListener(IOErrorEvent.IO_ERROR, errorHandler); _loader.removeEventListener(SecurityErrorEvent.SECURITY_ERROR, errorHandler); } catch(error:Error) { status.text = error.message; } } private function errorHandler(event:Event):void { status.text = "error"; unload(); } private function statusHandler(event:HTTPStatusEvent):void { if(event.status.toString().match(/^2/)) { status.text = "success"; unload(); } else { errorHandler(event); } } ]]> </mx:Script> <mx:Label id="status" /> I tried using ProgressEvents instead, but it seems that some 404 pages return content, so the status event will correctly identify if the page exists. Anyone have any ideas?

  • How to open AsyncTask from a Thread

    - by Abhishek
    In my application I have created a SplashScreen that will b shown for 5 Seconds and after that it executes an if else case depending upon the values stored in the Preference file. If Preference file contains values then the AsyncTask code will run else the Login form will load. When i try to run my application. The thread is going to the Login form with the help of intent but when it comes to AsyncTask my application shows a force close error message. This is my SplashScreen code: public class SplashScreen extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.splashscreen); Thread timer = new Thread() { public void run() { try { sleep(5000); } catch(InterruptedException e) { e.printStackTrace(); } finally { if(GoGolfPref.getEmail(SplashScreen.this)!=null && GoGolfPref.getPass(SplashScreen.this)!=null) { new LoadingScreen(SplashScreen.this, SplashScreen.this).execute("login_page", Login.url+GoGolfPref.getEmail(SplashScreen.this)+"/"+GoGolfPref.getPass(SplashScreen.this)); } else { Intent in = new Intent(SplashScreen.this, Login.class); startActivity(in); finish(); } } } }; timer.start(); } } This is the error I am getting: 08-29 07:25:58.040: E/AndroidRuntime(2365): FATAL EXCEPTION: Thread-10 08-29 07:25:58.040: E/AndroidRuntime(2365): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.os.Handler.<init>(Handler.java:121) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.Dialog.<init>(Dialog.java:101) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.AlertDialog.<init>(AlertDialog.java:63) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:80) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:76) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.LoadingScreen.<init>(LoadingScreen.java:130) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.SplashScreen$1.run(SplashScreen.java:32) How to get this working?

  • How can I use a class with the same name from another namespace in my class?

    - by Beau Simensen
    I have two classes with the same name in different namespaces. I want one of these classes to reference the other class. The reason is that I am migrating to some newer code and I want to update the old code to simply pass through to the newer code. Here is a super basic example: namespace project { namespace legacy { class Content { public: Content(const string& url) : url_(url) { } string url() { return url_; } private: string url_; }; }} // namespace project::legacy; namespace project { namespace current { class Content { public: Content(const string& url) : url_(url) {} string url() { return url_; } private: string url_; }} // namespace project::current; I expected to be able to do the following to project::legacy::Content, but I am having trouble with some linker issues. Is this an issue with how I'm trying to do this, or do I need to look more closely at my project files to see if I have some sort of weird dependency issues? #include "project/current/Content.h" namespace project { namespace legacy { class Content { public: Content(const string& url) : actualContent_(url) { } string url() { return actualContent_.url(); } private: project::current::Content actualContent_; }; }} // namespace project::legacy; The test application compiles fine if I try to reference an instance of project::current::Content but if I try to reference project::current::Content from project::legacy::Content I get an: undefined reference to `project::current::Content::Content(...)` UPDATE As it turns out, this was a GNU Autotoolset issue and was unrelated to the actual topic. Thanks to everyone for their help and suggestions!

  • How to simulate inner exception in C++

    - by Siva Chandran
    Basically I want to simulate .NET Exception.InnerException in C++. I want to catch exception from bottom layer and wrap it with another exception and throw again to upper layer. The problem here is I don't know how to wrap the catched exception inside another exception. struct base_exception : public std::exception { std::exception& InnerException; base_exception() : InnerException(???) { } // <---- what to initialize with base_exception(std::exception& innerException) : InnerException(innerException) { } }; struct func1_exception : public base_exception { const char* what() const throw() { return "func1 exception"; } }; struct func2_exception : public base_exception { const char* what() const throw() { return "func2 exception"; } }; void func2() { throw func2_exception(); } void func1() { try { func2(); } catch(std::exception& e) { throw func2_exception(e); // <--- is this correct? will the temporary object will be alive? } } int main(void) { try { func1(); } catch(base_exception& e) { std::cout << "Got exception" << std::endl; std::cout << e.what(); std::cout << "InnerException" << std::endl; std::cout << e.InnerException.what(); // <---- how to make sure it has inner exception ? } } In the above code listing I am not sure how to initialize the "InnerException" member when there is no inner exception. Also I am not sure whether the temporary object that is thrown from func1 will survive even after func2 throw?

  • NSMutableDictionary memory / address problem, release does not work?

    - by phil
    I am trying to create a NSMutableDictionary(dictA) with objectA. When I try to view my dictionary(NSLog), each key is pointing to the same address. I have an objectA_1 which is type objectA and used to setup the dictionary. Also, if I try to getObject, I always get the last key/value that was added to the dictionary. I tried setValue and got the same results. Is there something wrong with my objectA? Is the release method not working properly? Am I retaining when I shouldn't? Thank you. dictA = [[NSMutableDictionary alloc] init]; objectA *objectA = [[objectA alloc] init]; [dictA setObject:objectA_1 forKey:@"apple"]; [objectA_1 release]; [dictA setObject:objectA_1 forKey:@"japan"]; [objectA_1 release]; [dictA setObject:objectA_1 forKey:@"paris"]; [objectA_1 release]; [dictA setObject:objectA_1 forKey:@"pizza"]; [objectA_1 release]; //NSlog: apple = ""; japan = ""; paris = ""; pizza = "";

  • GoDaddy Subdomain Hosting Issue/Question with Disk Access (C#/ASP.NET 3.5)

    - by Vogel
    This isn't a very complicated scenario really, but as I start to type out the problem I'm realizing how convoluted it can become textually. Let me try and be very clear: First, the set up... I have a C#/ASP.NET web application that is publicly facing on my main domain (www), let's call it www.mysite.com. Nothing fancy, just a front-end that connects to SQL to display records. Then, I have a second C#/ASP.NET web application that is secured using forms authentication running on a subdomain, let's call it admin.mysite.com. This is a very light-weight CMS system to administer the public site. Now, the problem... Both of these sites run fine for basic tasks, however, my problem arises when I try to gain access to the file system for uploading. GoDaddy requires subdomains to run as a virtual directories under the main application in IIS (so the subdomains actually resolve/re-direct to www.mysite.com/admin when you type in admin.mysite.com), but because of this I am unable to write to my website root from the subfolder. Let me explain a little more... The CMS system (running as a virtual directory) gives the admin the ability to upload photos for display on the main site, the target folder of which is www.mysite.com/images - when attempting disk access from the root app, I am able to write to the virtual directory, but cannot do the opposite -- that is, write to the root from the virtual directory, getting security violations. If I can only upload to the /admin/ virtual directory, the entire point is moot because it's a secured folder that the public can't see! The only solution I can think of is to upload the files to the /admin/ virtual directory, then call a URL in the root that moves files from /admin/ back to the root, but that is entirely ghetto. I hope this post makes sense. Anyone else experience anything like this? The bottom line is that it seems virtual directories ONLY have access to themselves, and not their parent directories, no matter what credentials are used. Thanks!

  • Is there some advantage to filling a stack with nils and interpreting the "top" as the last non-nil value?

    - by dwilbank
    While working on a rubymonk exercise, I am asked to implement a stack with a hard size limit. It should return 'nil' if I try to push too many values, or if I try to pop an empty stack. My solution is below, followed by their solution. Mine passes every test I can give it in my IDE, while it fails rubymonk's test. But that isn't my question. Question is, why did they choose to fill the stack with nils instead of letting it shrink and grow like it does in my version? It just makes their code more complex. Here's my solution: class Stack def initialize(size) @max = size @store = Array.new end def pop empty? ? nil : @store.pop end def push(element) return nil if full? @store.push(element) end def size @store.size end def look @store.last end private def full? @store.size == @max end def empty? @store.size == 0 end end and here is the accepted answer class Stack def initialize(size) @size = size @store = Array.new(@size) @top = -1 end def pop if empty? nil else popped = @store[@top] @store[@top] = nil @top = @top.pred popped end end def push(element) if full? or element.nil? nil else @top = @top.succ @store[@top] = element self end end def size @size end def look @store[@top] end private def full? @top == (@size - 1) end def empty? @top == -1 end end

  • Rijndael managed: plaintext length detction

    - by sheepsimulator
    I am spending some time learning how to use the RijndaelManaged library in .NET, and developed the following function to test encrypting text with slight modifications from the MSDN library: Function encryptBytesToBytes_AES(ByVal plainText As Byte(), ByVal Key() As Byte, ByVal IV() As Byte) As Byte() ' Check arguments. If plainText Is Nothing OrElse plainText.Length <= 0 Then Throw New ArgumentNullException("plainText") End If If Key Is Nothing OrElse Key.Length <= 0 Then Throw New ArgumentNullException("Key") End If If IV Is Nothing OrElse IV.Length <= 0 Then Throw New ArgumentNullException("IV") End If ' Declare the RijndaelManaged object ' used to encrypt the data. Dim aesAlg As RijndaelManaged = Nothing ' Declare the stream used to encrypt to an in memory ' array of bytes. Dim msEncrypt As MemoryStream = Nothing Try ' Create a RijndaelManaged object ' with the specified key and IV. aesAlg = New RijndaelManaged() aesAlg.BlockSize = 128 aesAlg.KeySize = 128 aesAlg.Mode = CipherMode.ECB aesAlg.Padding = PaddingMode.None aesAlg.Key = Key aesAlg.IV = IV ' Create a decrytor to perform the stream transform. Dim encryptor As ICryptoTransform = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV) ' Create the streams used for encryption. msEncrypt = New MemoryStream() Using csEncrypt As New CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write) Using swEncrypt As New StreamWriter(csEncrypt) 'Write all data to the stream. swEncrypt.Write(plainText) End Using End Using Finally ' Clear the RijndaelManaged object. If Not (aesAlg Is Nothing) Then aesAlg.Clear() End If End Try ' Return the encrypted bytes from the memory stream. Return msEncrypt.ToArray() End Function Here's the actual code I am calling encryptBytesToBytes_AES() with: Private Sub btnEncrypt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEncrypt.Click Dim bZeroKey As Byte() = {&H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0} PrintBytesToRTF(encryptBytesToBytes_AES(bZeroKey, bZeroKey, bZeroKey)) End Sub However, I get an exception thrown on swEncrypt.Write(plainText) stating that the 'Length of the data to encrypt is invalid.' However, I know that the size of my key, iv, and plaintext are 16 bytes == 128 bits == aesAlg.BlockSize. Why is it throwing this exception? Is it because the StreamWriter is trying to make a String (ostensibly with some encoding) and it doesn't like &H0 as a value?

  • unable to implement HTTP Tunneling correctly in order to enable Java rmi calls over internet(and und

    - by Lokesh Kumar
    in my previous question :-How to Setup RMI Server under(NAT/ISP) Now,i m able to start my RMI server by Installing apache Tomcat 6.0 server. i have also installed servlet programs into apache Tomcat server in order to enable HTTP tunneling. my servlet codes:- (1) [SimplifiedServletHandler.java][2] (2) [ServletForwardCommand.java][3] these servlets resides inside :- C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\examples\WEB-INF\classes\ one more thing that i hv added to my CalcultorClient.java program:- try { RMISocketFactory. setSocketFactory(new sun.rmi.transport.proxy .RMIHttpToCGISocketFactory( )); }catch (IOException ignored) { System.out.println("Error :- ignored.getMessage()"); } But,when i try to make client connect with server(under ISP/NAT) i get the following Exception :- RemoteException java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is: java.io.IOException: HTTP request failed i don't know the correct reason behind this Exception.. but,i think that i haven't installed or invoke my servlet programs properly on server side. so,can anybody tell me the correct reason behind this error/Exception????? and if u think that it is servlet problem then tell me the correct procedure to run my serlvet program inside tomcat server.

  • Iphone: TabView + TableView

    - by OneTrickPonySoft
    I think I'm missing something simple, but I can't figure out exactly what it is. I'm trying to set up an App with a UITabViewController, and one of the Tabs will have a UITableView and UISearchBar (but no Navigation Controller). I set up the UITabViewController with all the tabs in interface builder, and the views are in their own xib files. The xib file for the tab with the UITableView is set up and connected as follows. Stuff in the browser: File's owner (Class is my custom class that is a child of UITableViewController) view - View View (class UIView, reference view - File's owner) contains: UITableView (if i try and set references to the data source / delegate, the app breaks) UISearchBar (unconfigured at the moment) This setup displays all the items and doesn't lock up, but I can't assign a DataSource without it crashing when i try and load the tab with the UITableView. What should I do to get data into this table, either in IB or code? My ideas are as follows: Implement custom UITableView class, hook up to table view in IB or to custom tableviewcontroller in Xcode. Pound head or laptop against the wall until it works. Update: Here's the error the simulator pushes to the console when I connect the Tableview's data source and delegate to File Owner (who's class is my custom tableviewcontroller). 2/14/09 6:59:12 PM TabBarWillbeRight[33172] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x523760'

  • Render action return View(); form problem

    - by Roger Rogers
    I'm new to MVC, so please bear with me. :-) I've got a strongly typed "Story" View. This View (story) can have Comments. I've created two Views (not partials) for my Comments controller "ListStoryComments" and "CreateStoryComment", which do what their names imply. These Views are included in the Story View using RenderAction, e.g.: <!-- List comments --> <h2>All Comments</h2> <% Html.RenderAction("ListStoryComments", "Comments", new { id = Model.Story.Id }); %> <!-- Create new comment --> <% Html.RenderAction("CreateStoryComment", "Comments", new { id = Model.Story.Id }); %> (I pass in the Story id in order to list related comments). All works as I hoped, except, when I post a new comment using the form, it returns the current (parent) View, but the Comments form field is still showing the last content I typed in and the ListStoryComments View isn’t updated to show the new story. Basically, the page is being loaded from cache, as if I had pressed the browser’s back button. If I press f5 it will try to repost the form. If I reload the page manually (reenter the URL in the browser's address bar), and then press f5, I will see my new content and the empty form field, which is my desired result. For completeness, my CreateStoryComment action looks like this: [HttpPost] public ActionResult CreateStoryComment([Bind(Exclude = "Id, Timestamp, ByUserId, ForUserId")]Comment commentToCreate) { try { commentToCreate.ByUserId = userGuid; commentToCreate.ForUserId = userGuid; commentToCreate.StoryId = 2; // hard-coded for testing _repository.CreateComment(commentToCreate); return View(); } catch { return View(); } }

  • Winforms, databinding, Listbox and textbox

    - by Snake
    Hi dear friends, I have a ListBox (MyListBox) on my screen, and a Textbox (MyTextBox). The ListBox is filled with a List(Of T), which are all custom items. Now I try to do this: The ListBox' datasource is the List(Of T). Now when an Item changes I want the textbox to be updated to a particular property of the selected item in my ListBox. In code this means: Me.MyListBox.DisplayMember = "SelectionName" Me.MyListBox.ValueMember = "Id" MyTextbox.DataBindings.Add(New Binding("Text", Me._listOfItems, "SelectedItem.Comment", True, DataSourceUpdateMode.OnPropertyChanged)) Me.MyListBox.DataSource = Me._listOfItems this does not work. But when I bind to SelectedValue instead of SelectedItem it works perfectly. The _listOfItems is declared as this: Dim _listOfItems As List(Of MyItem) = New List(Of MyItem)() Where MyItem is this: public class MyItem { public string SelectionName { get; set; } public int Id { get; set; } public string Comment { get; set; } } I tried overriding the ToString() in MyItem so that it would use that. But that doesn't work either. Anybody care to give it a try? Thanks! -Snakiej
