  • File not found on RSACryptoServiceProvider, service account permissions?

    - by Ben Scheirman
    Our web service wraps around a third party library that contains the following code. We are using an Active Directory service account in the IIS 6 app pool (no interactive login abilities). Our service fails with the error “The system cannot find the file specified”. We’ve traced the error to the “RSACryptoServiceProvider provider = new RSACryptoServiceProvider();”. The third party assembly depends on a x509 file based certificate for its encryption process and the Service Account has Read / Write access to the keys folder. Additionally, the service account has Read, Write, Modify rights to “C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys”. Code: StringBuilder builder = new StringBuilder(publicKeyData); builder.Replace("-----BEGIN CERTIFICATE-----", ""); builder.Replace("-----END CERTIFICATE-----", ""); X509Certificate2 certificate = new X509Certificate2( Convert.FromBase64String(builder.ToString())); string xmlString = certificate.PublicKey.Key.ToXmlString(false); RSACryptoServiceProvider provider = new RSACryptoServiceProvider(); //BOOM CspKeyContainerInfo containerInfo = provider.CspKeyContainerInfo; provider.PersistKeyInCsp = false; provider.FromXmlString(xmlString); loadedKeys.Add(key, provider); provider2 = provider; We cracked open FileMon and noticed that there is a FILE NOT FOUND for that AppPool, followed by another SUCCESS for the same exact file. I'm out of my element here, anybody have an idea as to why we're seeing this?

  • HTML inside webView

    - by Samuh
    I am posting some data to a server using DefaultHttpClient class and in the response stream I am getting a HTML file. I save the stream as a string and pass it onto another activity which contains a WebView to render this HTML on the screen: response = httpClient.execute(get); InputStream is = response.getEntity().getContent(); BufferedReader br = new BufferedReader(new InputStreamReader(is,"utf-8")); StringBuffer sb = new StringBuffer(); String line; while((line=br.readLine())!=null){ sb.append(line); sb.append("\n"); } is.close(); Intent intent = new Intent(this,Trial.class); intent.putExtra("trial",sb.toString()); startActivity(intent); Log.i("SB",sb.toString()); In Second Activity, the code to load the WebView reads: WebView browser = ((WebView)findViewById(R.id.trial_web)); browser.getSettings().setJavaScriptEnabled(true); browser.loadData(html,"text/html", "utf-8"); When I run this code, the WebView is not able to render the HTML content properly. It actually shows the HTML string in URL encoded format on the screen. Interestingly, If I copy the Loggers output to HTML file and then load this HTML in my WebView(using webview.loadurl(file:///assets/xyz.html)) everything works fine. I suspect some problem with character encoding. What is going wrong here? Please help. Thanks.

  • using System.Net.Mail To send smtp mail via google gets me a time out exception.

    - by Anicho
    Hey guys, I guess I got another asp.net question I am trying to send email using smtp authentication through google but I am constantly getting a timed out error and no idea what it might be from the following code its not my firewall or my isp blocking smtp ports so its most probably the code: MailMessage msg = new MailMessage(); String BodyMsg; BodyMsg = "Hey " + TxtBoxUsername.Text + "@" + "Welcome to Tiamo your username and password are:@Username: " + TxtBoxUsername.Text + "@Password: " + PasswordString + "@You have succesffully registered, you can now login." + "@Thank You@Tiamo Team"; BodyMsg = BodyMsg.Replace("@", System.Environment.NewLine); msg.To.Add(new MailAddress(TxtBoxEmail.Text)); msg.From = new MailAddress("[email protected]"); msg.Subject = "Re: Welcome to Tiamo"; msg.Body = BodyMsg; SmtpClient client = new SmtpClient() ; client.EnableSsl = true; client.Send(msg); and this is my web.config email smtp settings: <system.net> <mailSettings> <smtp from="[email protected]"> <network host="smtp.gmail.com" port="465" userName="[email protected]" password="MyLovelyPassword" defaultCredentials="true"/> </smtp> </mailSettings> Im completely exhausted so I thought the best thing is to pop up a question, hope you can help it will all be much appreciated... thanks anicho.

  • WPF Memory Leak on XP (CMilChannel, HWND)

    - by vanja.
    My WPF application leaks memory at about 4kb/s. The memory usage in Task Manager climbs constantly until the application crashes with an "Out of Memory" exception. By doing my own research I have found that the problem is discussed here: http://stackoverflow.com/questions/801589/track-down-memory-leak-in-wpf and #8 here: http://blogs.msdn.com/jgoldb/archive/2008/02/04/finding-memory-leaks-in-wpf-based-applications.aspx The problem described is: This is a leak in WPF present in versions of the framework up to and including .NET 3.5 SP1. This occurs because of the way WPF selects which HWND to use to send messages from the render thread to the UI thread. This sample destroys the first HWND created and starts an animation in a new Window. This causes messages sent from the render thread to pile up without being processed, effectively leaking memory. The solution offered is: The workaround is to create a new HwndSource first thing in your App class constructor. This MUST be created before any other HWND is created by WPF. Simply by creating this HwndSource, WPF will use this to send messages from the render thread to the UI thread. This assures all messages will be processed, and that none will leak. But I don't understand the solution! I have a subclass of Application that I am using and I have tried creating a window in that constructor but that has not solved the problem. Following the instructions given literally, it looks like I just need to add this to my Application constructor: new HwndSource(new HwndSourceParameters("MyApplication"));

  • Invalid Cast Exception ASP.NET C#

    I have a problem in this code: public static T[] GetExtras <T>(Type[] Types) { List<T> Res = new List<T>(); foreach (object Current in GetExtras(typeof(T), Types)) { Res.Add((T)Current);//this is the error } return Res.ToArray(); } public static object[] GetExtras(Type ExtraType, Type[] Types) { lock (ExtraType) { if (!ExtraType.IsInterface) return new object[] { }; List<object> Res = new List<object>(); bool found = false; found = (ExtraType == typeof(IExtra)); foreach (Type CurInterFace in ExtraType.GetInterfaces()) { if (found = (CurInterFace == typeof(IExtra))) break; } if (!found) return new object[] { }; foreach (Type CurType in Types) { found = false; if (!CurType.IsClass) continue; foreach (Type CurInterface in CurType.GetInterfaces()) { try { if (found = (CurInterface.FullName == ExtraType.FullName)) break; } catch { } } try { if (found) Res.Add(Activator.CreateInstance(CurType)); } catch { } } return Res.ToArray(); } } When I'm using this code in windows application it works! But I cant use it on ASP page. Why?

  • Multiple overlay items in android

    - by Bostjan
    I seem to be having a problem with using ItemizedOverlay and OveralyItems in it. I can get the first overlayItem to appear on the map but not any items after that. Code sample is on: http://www.anddev.org/multiple_overlay_items-t12171.html Quick overview here: public class Markers extends ItemizedOverlay { private Context ctx; private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); public Markers(Drawable defaultMarker, Context cont) { super(boundCenterBottom(defaultMarker)); this.ctx = cont; // TODO Auto-generated constructor stub } @Override protected OverlayItem createItem(int i) { // TODO Auto-generated method stub return mOverlays.get(i); } @Override public boolean onTap(GeoPoint p, MapView mapView) { // TODO Auto-generated method stub return super.onTap(p, mapView); } @Override protected boolean onTap(int index) { // TODO Auto-generated method stub Toast.makeText(this.ctx, mOverlays.get(index).getTitle().toString()+", Latitude: "+mOverlays.get(index).getPoint().getLatitudeE6(), Toast.LENGTH_SHORT).show(); return super.onTap(index); } @Override public int size() { // TODO Auto-generated method stub return mOverlays.size(); } public void addOverlay(OverlayItem item) { mOverlays.add(item); setLastFocusedIndex(-1); populate(); } public void clear() { mOverlays.clear(); setLastFocusedIndex(-1); populate(); }} Markers usersMarker = new Markers(user,overview.this); GeoPoint p = new GeoPoint((int) (lat * 1E6),(int) (lon * 1E6)); OverlayItem item = new OverlayItem(p,userData[0],userData[3]); item.setMarker(this.user); usersMarker.addOverlay(item); The lines after the class are just samples of how it's used the first marker shows up on the map but if I add any more they don't show up? Is there a problem with the populate() method? I tried calling it manually after adding all markers but it still didn't help. Please, if you have any idea what could be wrong, say so.

  • Resharper Live Template Macro that changes variable name upon exit

    - by Luhmann
    I would like to create a Resharper Live Template that changes all spaces to underscores ind my "fact" Live template variable $testname$: <Fact()> _ Public Sub $testnames$() ' Arrange $END$ ' Act ' Assert End Sub I have this: [Macro("applyRegex", ShortDescription = "Run on {#0:variable}", LongDescription = "")] class ApplyRegexMacro : IMacro { public string EvaluateQuickResult(IHotspotContext context, IList<string> arguments) { return Regex.Replace(arguments[0], " ", "_", RegexOptions.IgnoreCase); } public HotspotItems GetLookupItems(IHotspotContext context, IList<string> arguments) { return null; } public string GetPlaceholder() { return "placeholder"; } public bool HandleExpansion(IHotspotContext context, IList<string> arguments) { return false; } public ParameterInfo[] Parameters { get { return new[] { new ParameterInfo(ParameterType.String), new ParameterInfo(ParameterType.String), new ParameterInfo(ParameterType.VariableReference) }; } } } But this only runs when i press tab. I want the macro to run after I tab out of $testname$. I want to be able to just write the test name in a single line of text with spaces, and then the Macro turns all the spaces into underscores. Is this possible?

  • Seperating Javascript and Html, when dynamically adding html via javascript

    - by optician
    I am currently building a very dynamic table for a list application, which will basically perform basic CRUD functions via AJAX. What I would like to do is separate the visual design and javascript to the point where I can change the design side without touching the JS side. This would only work where the design stays roughly the same(i would like to use it for rapid protyping) Here is an example. <table> <tr><td>record-123</td><td>I am line 123</td><td>delete row</td></tr> <tr><td>record-124</td><td>I am line 124</td><td>delete row</td></tr> <tr><td>record-125</td><td>I am line 125</td><td>delete row</td></tr> <tr><td>add new record</td></tr> </table> Now, when I add a new record, I would like to insert a new row of html, but I would rather not put this html into the javascript file. What I am considering is creating a row like this on the page, near the table. <tr style='visble:none;' id='template-row'><td>record-id</td><td>content-area</td><td>delete row</td></tr> And when I come to add the new row, I search the page for the tags with the id=template-row , and then grab it, do a string replace on it, and then put it in the right place in the page. As long as the design doesn't shift radically, and I keep the placeholder strings the same, it means designs can be quickly modified without touching the js. Can any give any advice on a methodology like this?

  • AlertDialog in if-stetement doesn't show()

    - by Steffen Kern
    I have the following code: public void button_login(View view) { // Instantiate an AlertDialog.Builder with its constructor AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { /* User clicked OK button */ } }); // Preserve EditText values. EditText ET_username = (EditText) findViewById(R.id.username); EditText ET_password = (EditText) findViewById(R.id.password); String str_username = ET_username.toString(); String str_password = ET_password.toString(); // Intercept missing username and password. if(str_username.length() == 0) { builder.setMessage(R.string.hint_username_empty); AlertDialog dialog = builder.create(); dialog.show(); } } I have an activity that includes the two EditText-Views and a button. When I click the button the shown method will be called. My problem: The AlertDialog doesnt show up! When I put the create and show at beginning like this: // Instantiate an AlertDialog.Builder with its constructor AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { /* User clicked OK button */ } }); builder.setMessage(R.string.hint_username_empty); AlertDialog dialog = builder.create(); dialog.show(); // Preserve EditText values.

Any ideas why the dialog doesnt show up in the first place? Greetz, Steffen

  • saving WPF InkCanvas to a JPG - image is getting cropped

    - by Jason
    I have a WPF InkCanvas control I'm using to capture a signature in my application. The control looks like this - it's 700x300 However, when I save it as a JPG, the resulting image looks like this, also 700x300 The code I'm using to save sigPath = System.IO.Path.GetTempFileName(); MemoryStream ms = new MemoryStream(); FileStream fs = new FileStream(sigPath, FileMode.Create); RenderTargetBitmap rtb = new RenderTargetBitmap((int)inkSig.Width, (int)inkSig.Height, 96d, 96d, PixelFormats.Default); rtb.Render(inkSig); JpegBitmapEncoder encoder = new JpegBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(rtb)); encoder.Save(fs); fs.Close(); This is the XAML I'm using: <Window x:Class="Consent.Client.SigPanel" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Background="Transparent" Topmost="True" AllowsTransparency="True" Title="SigPanel" Left="0" Top="0" Height="1024" Width="768" WindowStyle ="None" ShowInTaskbar="False" ResizeMode="NoResize" WindowStartupLocation="CenterScreen" > <Border BorderThickness="1" BorderBrush="Black" Background='#FFFFFFFF' x:Name='DocumentRoot' Width='750' Height='400' CornerRadius='10'> <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center"> <TextBlock Name="txtLabel" FontSize="24" HorizontalAlignment="Center" >Label</TextBlock> <InkCanvas Opacity="1" Background="Beige" Name="inkSig" Width="700" Height="300" /> <StackPanel HorizontalAlignment="Center" Orientation="Horizontal"> <Button FontSize="24" Margin="10" Width="150" Name="btnSave" Click="btnSave_Click">Save</Button> <Button FontSize="24" Margin="10" Width="150" Name="btnCancel" Click="btnCancel_Click">Cancel</Button> <Button FontSize="24" Margin="10" Width="150" Name="btnClear" Click="btnClear_Click">Clear</Button> </StackPanel> </StackPanel> </Border> In the past this worked perfectly.

  • Trouble converting an MP3 file to a WAV file using Naudio

    - by WebDevHobo
    Naudio Library: http://naudio.codeplex.com/ I'm trying to convert an MP3 file to a WAV file, but I've run in to a small error. I know what's going wrong, but I don't really know how to go about fixing it. Here's the piece of code I'm running: private void button1_Click(object sender, EventArgs e) { using(Mp3FileReader reader = new Mp3FileReader(@"path\to\MP3")) { using(WaveFileWriter writer = new WaveFileWriter(@"C:\test.wav", new WaveFormat())) { int counter = 0; while(reader.Read(test, counter, test.Length + counter) != 0) { writer.WriteData(test, counter, test.Length + counter); counter += 512; } } } } reader.Read() goes into the Mp3FileReader class, and the method looks like this: public override int Read(byte[] sampleBuffer, int offset, int numBytes) { if (numBytes % waveFormat.BlockAlign != 0) //throw new ApplicationException("Must read complete blocks"); numBytes -= (numBytes % waveFormat.BlockAlign); return mp3Stream.Read(sampleBuffer, offset, numBytes); } mp3Stream is an object of the Stream class. The problem is: I'm getting an ArgumentException. MSDN says that this is because the sum of offset and numBytes is greater than the length of sampleBuffer. Documentation: http://msdn.microsoft.com/en-us/library/system.io.stream.read.aspx This happens because I increase the counter every time, but the size of the byte array test remains the same. What I've been wondering is: do I need to increase the size of the array dynamically, or do I need to find out the needed size at the beginning and set it right away? And also, instead of 512, the method in Mp3FileReader returns 365 the first time. Which is the size of a whole block. But I'm writing the full 512. I'm basically just using the read to check if I'm not at the end of the file yet. Do I need to catch the return value and do something with that, or am I good here?

  • C# unaccurate timer?

    - by Ivan
    Hi there, I'm developing an application and I need to get the current date from a server (it differs from the machine's date). I receive the date from the server and with a simple Split I create a new DateTime: globalVars.fec = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, int.Parse(infoHour[0]), int.Parse(infoHour[1]), int.Parse(infoHour[2])); globalVars is a class and fec is a public static variable so that I can access it anywhere in the application (bad coding I know...). Now I need to have a timer checking if that date is equal to some dates I have stored in a List and if it is equal I just call a function. List<DateTime> fechas = new List<DateTime>(); Before having to obtain the date from a server I was using computer's date, so to check if the dates matched I was using this: private void timerDatesMatch_Tick(object sender, EventArgs e) { DateTime tick = DateTime.Now; foreach (DateTime dt in fechas) { if (dt == tick) { //blahblah } } } Now I have the date from the server so DateTime.Now can't be used here. Instead I have created a new timer with Interval=1000 and on tick I'm adding 1 second to globalVars.fec using: globalVars.fec = globalVars.fec.AddSeconds(1); But the clock isn't accurate and every 30 mins the clock loses about 30 seconds. Is there another way of doing what I'm trying to do? I've thought about using threading.timer instead but I need to have access to other threads and non-static functions. Thanks in advance, Ivan

  • Reading a POP3 server with only TcpClient and StreamWriter/StreamReader

    - by WebDevHobo
    I'm trying to read mails from my live.com account, via the POP3 protocol. I've found the the server is pop3.live.com and the port if 587. I'm not planning on using a pre-made library, I'm using NetworkStream and StreamReader/StreamWriter for the job. I need to figure this out. So, any of the answers given here: http://stackoverflow.com/questions/44383/reading-email-using-pop3-in-c are not usefull. It's part of a larger program, but I made a small test to see if it works. Eitherway, i'm not getting anything. Here's the code I'm using, which I think should be correct. public Program() { string temp = ""; using(TcpClient tc = new TcpClient(new IPEndPoint(IPAddress.Parse("127.0.0.1"),8000))) { tc.Connect("pop3.live.com",587); using(NetworkStream nws = tc.GetStream()) { using(StreamReader sr = new StreamReader(nws)) { using(StreamWriter sw = new StreamWriter(nws)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); while(temp != ".") { temp += sr.ReadLine(); } } } } } Console.WriteLine(temp); } So, I'm sending from port 8000 on my machine to port 587, the hotmail pop3 port. And I'm getting nothing, and I'm out of ideas.

  • XML deserialization doubling up on entities

    - by Nathan Loding
    I have an XML file that I am attempting to deserialize into it's respective objects. It works great on most of these objects, except for one item that is being doubled up on. Here's the relevant portion of the XML: <Clients> <Client Name="My Company" SiteID="1" GUID="xxx-xxx-xxx-xxx"> <Reports> <Report Name="First Report" Path="/Custom/FirstReport"> <Generate>true</Generate> </Report> </Reports> </Client> </Clients> "Clients" is a List<Client> object. Each Client object has a List<Report> object within it. The issue is that when this XML is deserialized, the List<Report> object has a count of 2 -- the "First Report" Report object is in there twice. Why? Here's the C#: public class Client { [System.Xml.Serialization.XmlArray("Reports"), System.Xml.Serialization.XmlArrayItem(typeof(Report))] public List<Report> Reports; } public class Report { [System.Xml.Serialization.XmlAttribute("Name")] public string Name; public bool Generate; [System.Xml.Serialization.XmlAttribute("Path")] public string Path; } class Program { static void Main(string[] args) { List<Client> _clients = new List<Client>(); string xmlFile = "myxmlfile.xml"; System.Xml.Serialization.XmlSerializer xmlSerializer = new System.Xml.Serialization.XmlSerializer(typeof(List<Client>), new System.Xml.Serialization.XmlRootAttribute("Clients")); using (FileStream stream = new FileStream(xmlFile, FileMode.Open)) { _clients = xmlSerializer.Deserialize(stream) as List<Client>; } foreach(Client _client in _clients) { Console.WriteLine("Count: " + _client.Reports.Count); // This write "2" foreach(Report _report in _client.Reports) { Console.WriteLine("Name: " + _report.Name); // Writes "First Report" twice } } } }

  • Can't ssh to ec2 permission denied (publickey)

    - by Chris Barnes
    I have existing instances running and I can connect to them fine.

  • String assembly by StringBuilder vs StringWriter and PrintWriter

    - by CPerkins
    I recently encountered an idiom I haven't seen before: string assembly by StringWriter and PrintWriter. I mean, I know how to use them, but I've always used StringBuilder. Is there a concrete reason for preferring one over the other? The StringBuilder method seems much more natural to me, but is it just style? I've looked at several questions here (including this one which comes closest: http://stackoverflow.com/questions/602279/stringwriter-or-stringbuilder ), but none in which the answers actually address the question of whether there's a reason to prefer one over the other for simple string assembly. This is the idiom I've seen and used many many times: string assembly by StringBuilder: public static String newline = System.getProperty("line.separator"); public String viaStringBuilder () { StringBuilder builder = new StringBuilder(); builder.append("first thing" + newline); builder.append("second thing" + newline); // ... several things builder.append("last thing" + newline); return builder.toString(); } And this is the new idiom: string assembly by StringWriter and PrintWriter: public String viaWriters() { StringWriter stringWriter = new StringWriter(); PrintWriter printWriter = new PrintWriter(stringWriter); printWriter.println("first thing"); printWriter.println("second thing"); // ... several things printWriter.println("last thing"); printWriter.flush(); printWriter.close(); return stringWriter.toString(); }

  • Eclipse Plugin does not work in FlashBuilder/FlexBuilder Standalone

    - by Janosch
    Hi, created an Eclipse plugin that contributes to the UI by a new project wizard a new menu in the context menu of projects in the Package Explorer a new project nature + builder a new preference page for the plugin The plugin works fine when installed in a normal Eclipse instance with Flex/Flashbuilder as plugin. The problem now is, that the plugin never gets activated when i install it in a Flex/Flashbuilder Standalone instance. Neither of the features described above is available. I even have no idea how to debug this, error-log (workspace/.metadata/.log) the following message appears, (but i dont think it is related to the problem) !ENTRY org.eclipse.ui.workbench 2 0 2009-07-20 17:51:17.984 !MESSAGE A handler conflict occurred. This may disable some commands. !SUBENTRY 1 org.eclipse.ui.workbench 2 0 2009-07-20 17:51:17.984 !MESSAGE Conflict for 'org.eclipse.ui.navigate.openResource': HandlerActivation(commandId=org.eclipse.ui.navigate.openResource, handler=ActionDelegateHandlerProxy(null,org.eclipse.ui.internal.ide.handlers.OpenResourceHandler), expression=AndExpression(ActionSetExpression(org.eclipse.ui.NavigateActionSet,org.eclipse.ui.internal.WorkbenchWindow@1c45731),WorkbenchWindowExpression(org.eclipse.ui.internal.WorkbenchWindow@1c45731)),sourcePriority=16640) HandlerActivation(commandId=org.eclipse.ui.navigate.openResource, handler=ActionDelegateHandlerProxy(null,org.eclipse.ui.internal.ide.handlers.OpenResourceHandler), expression=AndExpression(ActionSetExpression(com.adobe.flexbuilder.standalone.navigate,org.eclipse.ui.internal.WorkbenchWindow@1c45731),WorkbenchWindowExpression(org.eclipse.ui.internal.WorkbenchWindow@1c45731)),sourcePriority=16640) In the "Configuration Details" my feature doesn't show up in the *** Features: section and my plugin doesn't show up in the *** Plugin-in Registry: section. But they appear under Configured features and Configured plug-ins. Starting FlashBuilder with -clean didn't solve the problem. (the start command is now "C:\Programme\Adobe\Flash Builder Beta\Gumbo.exe" -clean) My plugin depends on org.eclipse.ui, org.eclipse.core.runtime, org.eclipse.core.resources, com.adobe.flexbuilder.project com.adobe.flexbuilder.project.ui com.adobe.flexbuilder.ui All of these should be available, as i see it. (and an error should be generated if they were not, i hope)

  • Can I tell Castle Windsor to create a component in a separate AppDomain?

    - by Michael L Perry
    I've created a multi-threaded service that uses Castle Windsor to create components to run on separate threads. I Resolve an component by name with parameters for each thread. I'm running into concurrency problems with a 3rd party library used by the components. I suspect that isolating those components in separate AppDomains will resolve the problem. Is there a way to have Resolve create the component using a different AppDomain? private ActivityThread NewActivityThread(ActivityInstance activityInstance) { // Set up the creation arguments. System.Collections.IDictionary arguments = new Dictionary<string, string>(); activityInstance.Parameters.ForEach(p => arguments.Add(p.Name, p.Value)); // Get the activity handler from the container. IActivity activity = Program.Container.Resolve<IActivity>(activityInstance.Name, arguments); // Create a thread for the activity. ActivityThread thread = new ActivityThread(activity, activityInstance, _nextActivityID++); return thread; } public ActivityThread(IActivity activity, ActivityInstance instance, int id) { _activity = activity; _instance = instance; _id = id; } public void Start() { if (_thread == null) { // Create a new thread to run this activity. _thread = new Thread(delegate() { _activity.Run(); }); _thread.Name = _activity.ToString(); _thread.SetApartmentState(ApartmentState.STA); _thread.Start(); } }

  • Generating scala AST for recursive method.

    - by scout
    I am generating the scala AST using the following code: val setting = new Settings(error) val reporter = new ConsoleReporter(setting, in, out) { override def displayPrompt = () } val compiler = new Global(setting, reporter) with ASTExtractor{ override def onlyPresentation = true } //setting.PhasesSetting("parser", "parserPhase") val run = new compiler.Run val sourceFiles:List[String] = List("Test.scala") run.compile(sourceFiles.toList) I guess this is the standard code used to run the compiler in the code and generate the AST to work with. The above code worked fine for any valid scala code in Test.scala till now. When I use a recursive function in Test.scala, like def xMethod(x:Int):Int = if(x == 0) -1 else xMethod(x-1) It gives me a java.lang.NullPointerException. The top few lines of the stack trace look like this at scala.tools.nsc.typechecker.Typers$Typer.checkNoDoubleDefsAndAddSynthetics$1(Typers.scala:2170) at scala.tools.nsc.typechecker.Typers$Typer.typedStats(Typers.scala:2196) at scala.tools.nsc.typechecker.Typers$Typer.typedBlock(Typers.scala:1951) at scala.tools.nsc.typechecker.Typers$Typer.typed1(Typers.scala:3815) at scala.tools.nsc.typechecker.Typers$Typer.typed(Typers.scala:4124) at scala.tools.nsc.typechecker.Typers$Typer.typed(Typers.scala:4177) at scala.tools.nsc.transform.TailCalls$TailCallElimination.transform(TailCalls.scala:199) The code works fine for a method like def aMethod(c:Int):Int = { bMethod(c) } def bMethod(x:Int):Int = aMethod(x) Please let me know if recursive functions need any other setting.

  • Static factory pattern with EJB3/JBoss

    - by purecharger
    I'm fairly new to EJBs and full blown application servers like JBoss, having written and worked with special purpose standalone Java applications for most of my career, with limited use of JEE. I'm wondering about the best way to adapt a commonly used design pattern to EJB3 and JBoss: the static factory pattern. In fact this is Item #1 in Joshua Bloch's Effective Java book (2nd edition) I'm currently working with the following factory: public class CredentialsProcessorFactory { private static final Log log = LogFactory.getLog(CredentialsProcessorFactory.class); private static Map<CredentialsType, CredentialsProcessor> PROCESSORS = new HashMap<CredentialsType, CredentialsProcessor>(); static { PROCESSORS.put(CredentialsType.CSV, new CSVCredentialsProcessor()); } private CredentialsProcessorFactory() {} public static CredentialsProcessor getProcessor(CredentialsType type) { CredentialsProcessor p = PROCESSORS.get(type); if(p == null) throw new IllegalArgumentException("No CredentialsProcessor registered for type " + type.toString()); return p; } However, in the implementation classes of CredentialsProcessor, I require injected resources such as a PersistenceContext, so I have made the CredentialsProcessor interface a @Local interface, and each of the impl's marked with @Stateless. Now I can look them up in JNDI and use the injected resources. But now I have a disconnect because I am not using the factory anymore. My first thought was to change the getProcessor(CredentialsType) method to do a JNDI lookup and return the SLSB instance that is required, but then I need to configure and pass the proper qualified JNDI name. Before I go down that path, I wanted to do more research on accepted practices. How is this design pattern treated in EJB3 / JEE?

  • Soap Negotiation Exception with BasicHttpBinding

    - by kyliod
    I have a wcf client/server application that I'm trying to get deployed at a client location. I believe it's a cross-domain issue, as we've deployed it successfully on the same computer. I'm currently using basichttpbinding and a custombinding that just uses Soap1.2: if (!useBasic) { CustomBinding binding = new CustomBinding(); TextMessageEncodingBindingElement encoding = new TextMessageEncodingBindingElement(MessageVersion.Soap12, System.Text.Encoding.UTF8); HttpTransportBindingElement transport = new HttpTransportBindingElement(); transport.MaxReceivedMessageSize = BindingConstants.MaxStringContentLength; binding.Elements.Add(encoding); binding.Elements.Add(transport); return binding; } else { BasicHttpBinding binding = new BasicHttpBinding(); binding.MaxReceivedMessageSize = BindingConstants.MaxStringContentLength; return binding; } However the client tells me that they get an error "SOAP security negotiation with 'XXXXXXXXXXXX' for target 'XXXXXXXXXXX' failed. See inner exception for details." Now I haven't gotten the inner exceptions yet, but everything I research online tells me that BasicHttpBinding should fix this, however they tell me they are using BasicHttpBinding. Is this error possible with BasicHttpBinding like how I have mine set up above? Also, when I check my BasicHttpBinding.Security.Message.ClientCredentialType, it says UserName. Does this even matter if my Security.Mode is "None"? Thanks.
