  • Checking for valid document files

    - by sweb
    I need a simple way to check if my files are valid documents (pdf, doc, docx, ppt, pptx, xls, xlsx, odt, ods, odp and etc). I can't use file because magic does not work well at all. For example, for PDF files, this is my output. sweb@sweb-laptop: /media/files/ebooks/PDF and CHM$ file --mime *. Pdf PHP 5 for Dummies. Pdf: application/pdf; charset=binary PHP 6 and MySQL 5 for Dynamic Web Sites. Pdf: application/octet-stream; charset=binary PHP6 and MySQL Bible. Pdf: application/pdf; charset=binary PHP6.pdf: application/octet-stream; charset=binary PHP and MySQL for Dummies SE. Pdf: application/pdf; charset=binary For example, I use abiword – which is a good tool – but it converts any format. It doesn't check for valid documents: abiword --to=txt --to-name=output.txt audio.mp3 Is there any command available to check for valid documents then?

  • C# creating a queue to handle jobs triggered by FileSystemWatcher

    - by John S
    I have built a small tray app that will watch a folder and when a new file is added it runs a job. The job is to watch for video files and convert them to .mp4 using handBrakeCli. I have all this logic worked out. The problem I run into is that if there is more than one file I want it to queue the job til the prior one is complete. I am fairly new to c# and I am not sure of the best way to handle this. one idea is to create a queue somehow, a file to store the commands in order maybe, then execute the next one after the process is complete. We are dealing with large movie files here so it can take a while. I am doing this on a quad core with 8gb of RAM and it seems to generally take about 30mins to complete a full length movie. here is the code I have so far. there are some bits in here that are for future functionality so it refers to some classes that you wont see but it doesnt matter as they arent used here. any suggestions are welcome. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; using System.Diagnostics; using System.Threading; namespace movie_converter { public partial class Form1 : Form { public Form1() { InitializeComponent(); } string hbCli; string cmd; string file; string strfilter = "*.*"; string[] filter = new string[3] { ".mkv", ".avi", ".wmv" }; //static list of types List<string> Ext = new List<string>(); //list of extensions to watch (dynamic) NotifyIcon notifyIcon = new System.Windows.Forms.NotifyIcon(); private void SetUpTrayIcon() { notifyIcon.BalloonTipText = "Movie Converter is running minimized."; notifyIcon.BalloonTipTitle = "I'm still here"; notifyIcon.Text = "John's movie converter"; notifyIcon.Icon = new Icon(@"C:\\Users\\John\\Pictures\\appicon.ico"); notifyIcon.Click += new EventHandler(notifyIcon_Click); if (notifyIcon != null) { notifyIcon.Visible = true; notifyIcon.ShowBalloonTip(2000); } } private void Form_Resize(object sender, EventArgs e) { if (WindowState == FormWindowState.Minimized) { this.Hide(); SetUpTrayIcon(); } } private void notifyIcon_Click(object sender, EventArgs e) { this.Show(); this.WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } public void Watcher() { FileSystemWatcher watcher = new FileSystemWatcher(); watcher.Path = textBox1.Text + "\\"; //path to watch watcher.Filter = strfilter; //what types to look for set to * and i will filter later as it cant accept an array watcher.NotifyFilter = NotifyFilters.FileName | NotifyFilters.DirectoryName; //properties to look at watcher.IncludeSubdirectories = true; //scan subdirs watcher.Created += new FileSystemEventHandler(OnChanged); //TODO: make this only run if the files are of a certain type watcher.EnableRaisingEvents = true; // start the watcher } static bool IsFileLocked(FileInfo file) { FileStream stream = null; try { stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None); } catch (IOException) { //the file is unavailable because it is: //still being written to //or being processed by another thread //or does not exist (has already been processed) return true; } finally { if (stream != null) stream.Close(); } //file is not locked return false; } // Define the event handlers. private void OnChanged(object source, FileSystemEventArgs e) { string sFile = e.FullPath; //check that file is available FileInfo fileInfo = new FileInfo(sFile); while (IsFileLocked(fileInfo)) { Thread.Sleep(500); } if (System.Diagnostics.Process.GetProcessesByName("HandBrakeCLI").Length != 0) { Thread.Sleep(500); } else { //hbOptions hbCl = new hbOptions(); //hbCli = hbCl.HbCliOptions(); if (textBox3.Text != "") { hbCli = textBox3.Text.ToString(); } else { hbCli = "-e x264 -q 20 -B 160"; } string t = e.Name; string s = t.Substring(0, t.Length - 4); //TODO: fix this its not reliable file = e.FullPath; string opath = textBox1.Text.ToString(); cmd = "-i \"" + file + "\" -o \"" + opath + "\\" + s + ".mp4\" " + hbCli; try { for (int i = 0; i < Ext.Count(); i++) { if (e.Name.Contains(Ext[i])) { Process hb = new Process(); hb.StartInfo.FileName = "D:\\Apps\\Handbrake\\Install\\Handbrake\\HandBrakeCLI.exe"; hb.StartInfo.Arguments = cmd; notifyIcon.BalloonTipTitle = "Now Converting"; notifyIcon.BalloonTipText = file; notifyIcon.ShowBalloonTip(2000); hb.Start(); } } } catch (Exception ex) { MessageBox.Show(ex.Message); } } } private void button1_Click(object sender, EventArgs e) //ok button { //add each array item to the list for (int i = 0; i < filter.Count(); i++) { Ext.Add(filter[i]); } if (textBox1.Text != "" && textBox1.Text.Length > 2) { Watcher(); //call watcher to run } this.WindowState = FormWindowState.Minimized; } private void button2_Click(object sender, EventArgs e) //browse button { //broswe button DialogResult result = folderBrowserDialog1.ShowDialog(); if (result == DialogResult.OK) { textBox1.Text = folderBrowserDialog1.SelectedPath; } } private void button3_Click(object sender, EventArgs e) //commands button { Process np = new Process(); np.StartInfo.FileName = "notepad.exe"; np.StartInfo.Arguments = "hbCLI.txt"; np.Start(); } private void button4_Click(object sender, EventArgs e) //options button { hbOptions options = new hbOptions(); options.ShowDialog(); } private void button5_Click(object sender, EventArgs e) //exit button { this.Close(); } private void Form1_Load(object sender, EventArgs e) { this.Resize += Form_Resize; } } }

  • Implementation of ZipCrypto / Zip 2.0 encryption in java

    - by gomesla
    I'm trying o implement the zipcrypto / zip 2.0 encryption algoritm to deal with encrypted zip files as discussed in http://www.pkware.com/documents/casestudies/APPNOTE.TXT I believe I've followed the specs but just can't seem to get it working. I'm fairly sure the issue has to do with my interpretation of the crc algorithm. The documentation states CRC-32: (4 bytes) The CRC-32 algorithm was generously contributed by David Schwaderer and can be found in his excellent book "C Programmers Guide to NetBIOS" published by Howard W. Sams & Co. Inc. The 'magic number' for the CRC is 0xdebb20e3. The proper CRC pre and post conditioning is used, meaning that the CRC register is pre-conditioned with all ones (a starting value of 0xffffffff) and the value is post-conditioned by taking the one's complement of the CRC residual. Here is the snippet that I'm using for the crc32 public class PKZIPCRC32 { private static final int CRC32_POLYNOMIAL = 0xdebb20e3; private int crc = 0xffffffff; private int CRCTable[]; public PKZIPCRC32() { buildCRCTable(); } private void buildCRCTable() { int i, j; CRCTable = new int[256]; for (i = 0; i <= 255; i++) { crc = i; for (j = 8; j > 0; j--) if ((crc & 1) == 1) crc = (crc >>> 1) ^ CRC32_POLYNOMIAL; else crc >>>= 1; CRCTable[i] = crc; } } private int crc32(byte buffer[], int start, int count, int lastcrc) { int temp1, temp2; int i = start; crc = lastcrc; while (count-- != 0) { temp1 = crc >>> 8; temp2 = CRCTable[(crc ^ buffer[i++]) & 0xFF]; crc = temp1 ^ temp2; } return crc; } public int crc32(int crc, byte buffer) { return crc32(new byte[] { buffer }, 0, 1, crc); } } Below is my complete code. Can anyone see what I'm doing wrong. package org.apache.commons.compress.archivers.zip; import java.io.IOException; import java.io.InputStream; public class ZipCryptoInputStream extends InputStream { public class PKZIPCRC32 { private static final int CRC32_POLYNOMIAL = 0xdebb20e3; private int crc = 0xffffffff; private int CRCTable[]; public PKZIPCRC32() { buildCRCTable(); } private void buildCRCTable() { int i, j; CRCTable = new int[256]; for (i = 0; i <= 255; i++) { crc = i; for (j = 8; j > 0; j--) if ((crc & 1) == 1) crc = (crc >>> 1) ^ CRC32_POLYNOMIAL; else crc >>>= 1; CRCTable[i] = crc; } } private int crc32(byte buffer[], int start, int count, int lastcrc) { int temp1, temp2; int i = start; crc = lastcrc; while (count-- != 0) { temp1 = crc >>> 8; temp2 = CRCTable[(crc ^ buffer[i++]) & 0xFF]; crc = temp1 ^ temp2; } return crc; } public int crc32(int crc, byte buffer) { return crc32(new byte[] { buffer }, 0, 1, crc); } } private static final long ENCRYPTION_KEY_1 = 0x12345678; private static final long ENCRYPTION_KEY_2 = 0x23456789; private static final long ENCRYPTION_KEY_3 = 0x34567890; private InputStream baseInputStream = null; private final PKZIPCRC32 checksumEngine = new PKZIPCRC32(); private long[] keys = null; public ZipCryptoInputStream(ZipArchiveEntry zipEntry, InputStream inputStream, String passwd) throws Exception { baseInputStream = inputStream; // Decryption // ---------- // PKZIP encrypts the compressed data stream.

  • .NET file Decryption - Bad Data

    - by Jon
    I am in the process of rewriting an old application. The old app stored data in a scoreboard file that was encrypted with the following code: private const String SSecretKey = @"?B?n?Mj?"; public DataTable GetScoreboardFromFile() { FileInfo f = new FileInfo(scoreBoardLocation); if (!f.Exists) { return setupNewScoreBoard(); } DESCryptoServiceProvider DES = new DESCryptoServiceProvider(); //A 64 bit key and IV is required for this provider. //Set secret key For DES algorithm. DES.Key = ASCIIEncoding.ASCII.GetBytes(SSecretKey); //Set initialization vector. DES.IV = ASCIIEncoding.ASCII.GetBytes(SSecretKey); //Create a file stream to read the encrypted file back. FileStream fsread = new FileStream(scoreBoardLocation, FileMode.Open, FileAccess.Read); //Create a DES decryptor from the DES instance. ICryptoTransform desdecrypt = DES.CreateDecryptor(); //Create crypto stream set to read and do a //DES decryption transform on incoming bytes. CryptoStream cryptostreamDecr = new CryptoStream(fsread, desdecrypt, CryptoStreamMode.Read); DataTable dTable = new DataTable("scoreboard"); dTable.ReadXml(new StreamReader(cryptostreamDecr)); cryptostreamDecr.Close(); fsread.Close(); return dTable; } This works fine. I have copied the code into my new app so that I can create a legacy loader and convert the data into the new format. The problem is I get a "Bad Data" error: System.Security.Cryptography.CryptographicException was unhandled Message="Bad Data.\r\n" Source="mscorlib" The error fires at this line: dTable.ReadXml(new StreamReader(cryptostreamDecr)); The encrypted file was created today on the same machine with the old code. I guess that maybe the encryption / decryption process uses the application name / file or something and therefore means I can not open it. Does anyone have an idea as to: A) Be able explain why this isn't working? B) Offer a solution that would allow me to be able to open files that were created with the legacy application and be able to convert them please? Here is the whole class that deals with loading and saving the scoreboard: using System; using System.Collections.Generic; using System.Text; using System.Security.Cryptography; using System.Runtime.InteropServices; using System.IO; using System.Data; using System.Xml; using System.Threading; namespace JawBreaker { [Serializable] class ScoreBoardLoader { private Jawbreaker jawbreaker; private String sSecretKey = @"?B?n?Mj?"; private String scoreBoardFileLocation = ""; private bool keepScoreBoardUpdated = true; private int intTimer = 180000; public ScoreBoardLoader(Jawbreaker jawbreaker, String scoreBoardFileLocation) { this.jawbreaker = jawbreaker; this.scoreBoardFileLocation = scoreBoardFileLocation; } // Call this function to remove the key from memory after use for security [System.Runtime.InteropServices.DllImport("KERNEL32.DLL", EntryPoint = "RtlZeroMemory")] public static extern bool ZeroMemory(IntPtr Destination, int Length); // Function to Generate a 64 bits Key. private string GenerateKey() { // Create an instance of Symetric Algorithm.

  • Communicating between C# application and Android app via bluetooth

    The android application acts as a server in this case. I have a main activity which creates a Thread to handle serverSocket and a different thread to handle the socket connection.

The errors i am facing are 1) My logcat shows this debug log Error while doing socket.connect()1 java.io.IOException: File descriptor in bad state Message: File descriptor in bad state Localized Message: File descriptor in bad state Received : Testing Connection Count of Thread is : 1 2) When i try to send something via C# app the second time, this exception is thrown: A first chance exception of type 'System.InvalidOperationException' occurred in System.dll System.InvalidOperationException: BeginConnect cannot be called while another asynchronous operation is in progress on the same Socket. at System.Net.Sockets.Socket.DoBeginConnect(EndPoint endPointSnapshot, SocketAddress socketAddress, LazyAsyncResult asyncResult) at System.Net.Sockets.Socket.BeginConnect(EndPoint remoteEP, AsyncCallback callback, Object state) at InTheHand.Net.Bluetooth.Msft.SocketBluetoothClient.BeginConnect(BluetoothEndPoint remoteEP, AsyncCallback requestCallback, Object state) at InTheHand.Net.Sockets.BluetoothClient.BeginConnect(BluetoothEndPoint remoteEP, AsyncCallback requestCallback, Object state) at InTheHand.Net.Sockets.BluetoothClient.BeginConnect(BluetoothAddress address, Guid service, AsyncCallback requestCallback, Object state) at BTSyncClient.Form1.connect() in c:\users\----\documents\visual studio 2010\Projects\TestClient\TestClient\Form1.cs:line 154 I only know android application programming and i designed the C# by learning bit and pieces.

  • Android - doInBackground() error in AsyncTask

    - by AimanB
    What my app here basically does is it captures a photo or import from gallery, and when the Upload button is pressed, the image will be uploaded to a localhost server. Before I implemented AsyncTask into the process, it doesn't have any problem uploading whatsoever. Now that I've put AsyncTask, everything went wrong. I don't know which part that I do wrong in this phase. This is what logcat shows when I try to upload an image file: 10-28 17:23:25.989: E/AndroidRuntime(3356): FATAL EXCEPTION: AsyncTask #5 10-28 17:23:25.989: E/AndroidRuntime(3356): java.lang.RuntimeException: An error occured while executing doInBackground() 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$3.done(AsyncTask.java:299) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:352) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.setException(FutureTask.java:219) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.run(FutureTask.java:239) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:230) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1080) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:573) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.lang.Thread.run(Thread.java:856) 10-28 17:23:25.989: E/AndroidRuntime(3356): Caused by: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.Handler.<init>(Handler.java:197) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.Handler.<init>(Handler.java:111) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast$TN.<init>(Toast.java:324) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast.<init>(Toast.java:91) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast.makeText(Toast.java:238) 10-28 17:23:25.989: E/AndroidRuntime(3356): at com.aiman.webshopper.UploadImageActivity$1execMultiPostAsync.doInBackground(UploadImageActivity.java:268) 10-28 17:23:25.989: E/AndroidRuntime(3356): at com.aiman.webshopper.UploadImageActivity$1execMultiPostAsync.doInBackground(UploadImageActivity.java:1) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$2.call(AsyncTask.java:287) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.run(FutureTask.java:234) This is my code for the Upload activity: public class UploadImageActivity extends Activity implements OnItemSelectedListener { InputStream inputStream;

  • Setting Key Usage attributes with Makecert

    - by nlawalker
    Is it possible to set Key Usage attributes using makecert, or any other tool I can use to generate my own test certificates? The reason I'm interested is that certificates used for BizTalk Server AS2 transport require a key usage of Digital Signature for signing and Data Encipherment or Key Encipherment for encryption/decryption, and I want to play around with this feature. I see how to set enhanced key usage attributes with makecert, but not key usage.

  • WCF: Using Streaming and Username/Password authentication at the same time

    - by Kay
    Hi, I have a WCF Service with the following requirements: a) The client requests a file from the server which is transferred as a Stream. Files may be 100MB or larger. I need streaming or chucking or whatever to make sure that IIS is not loading the whole package into memory before starting to send it. b) The client will transfer an ID to identify the file to be downloaded. The user should be authenticated by providing username/password. c) While the username/password part of the communication needs to be encrypted, encryption of the downloaded file is optional for our use case. My other services, where I am returning smaller files, I am using the following binding: <ws2007HttpBinding> <binding name="ws2007HttpExtern" maxReceivedMessageSize="65536000"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </ws2007HttpBinding> But, as I said, that is no good for streaming (Message encryption needs the complete message to encrypt and that is not the case when streaming). So, I asked Microsoft support and I got more or less the following proposal: <bindings> <basicHttpBinding> <binding name="basicStreaming" messageEncoding="Mtom" transferMode="StreamedResponse"> <security mode="Transport"> <transport clientCredentialType="Basic" /> </security> </binding> </bindings> <services> <service behaviorConfiguration="MyProject.WCFInterface.DownloadBehavior" name="MyProject.WCFInterface.DownloadFile"> <endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicStreaming" contract="MyProject.WCFInterface.IDownloadFile" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="MyProject.WCFInterface.DownloadBehavior"> <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> When I use this, I get the following error message: Could not find a base address that matches scheme https for the endpoint with binding BasicHttpBinding. Registered base address schemes are [http]. I am using the Web Development Server so far (for production IIS7). I have two questions. a) How would you configure WCF to achieve the goal? b) If the MS proposal is good: What I am doing wrong, the error message does not really help me. Thanks.

  • "No message serializer has been configured" error when starting NServiceBus endpoint

What is strange is that in my endpoint configuration, I am specifying to use the XmlSerializer for message serialization. I don't see any other errors in the console output preceding the error message. What am I missing? Thanks, Steve

  • "Content is not allowed in prolog" when parsing perfectly valid XML on GAE

    - by Adrian Petrescu
    Hey guys, I've been beating my head against this absolutely infuriating bug for the last 48 hours, so I thought I'd finally throw in the towel and try asking here before I throw my laptop out the window. I'm trying to parse the response XML from a call I made to AWS SimpleDB. The response is coming back on the wire just fine; for example, it may look like: <?xml version="1.0" encoding="utf-8"?> <ListDomainsResponse xmlns="http://sdb.amazonaws.com/doc/2009-04-15/"> <ListDomainsResult> <DomainName>Audio</DomainName> <DomainName>Course</DomainName> <DomainName>DocumentContents</DomainName> <DomainName>LectureSet</DomainName> <DomainName>MetaData</DomainName> <DomainName>Professors</DomainName> <DomainName>Tag</DomainName> </ListDomainsResult> <ResponseMetadata> <RequestId>42330b4a-e134-6aec-e62a-5869ac2b4575</RequestId> <BoxUsage>0.0000071759</BoxUsage> </ResponseMetadata> </ListDomainsResponse> I pass in this XML to a parser with XMLEventReader eventReader = xmlInputFactory.createXMLEventReader(response.getContent()); and call eventReader.nextEvent(); a bunch of times to get the data I want. Here's the bizarre part -- it works great inside the local server. The response comes in, I parse it, everyone's happy. The problem is that when I deploy the code to Google App Engine, the outgoing request still works, and the response XML seems 100% identical and correct to me, but the response fails to parse with the following exception: com.amazonaws.http.HttpClient handleResponse: Unable to unmarshall response (ParseError at [row,col]:[1,1] Message: Content is not allowed in prolog.): <?xml version="1.0" encoding="utf-8"?> <ListDomainsResponse xmlns="http://sdb.amazonaws.com/doc/2009-04-15/"><ListDomainsResult><DomainName>Audio</DomainName><DomainName>Course</DomainName><DomainName>DocumentContents</DomainName><DomainName>LectureSet</DomainName><DomainName>MetaData</DomainName><DomainName>Professors</DomainName><DomainName>Tag</DomainName></ListDomainsResult><ResponseMetadata><RequestId>42330b4a-e134-6aec-e62a-5869ac2b4575</RequestId><BoxUsage>0.0000071759</BoxUsage></ResponseMetadata></ListDomainsResponse> javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1] Message: Content is not allowed in prolog. at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(Unknown Source) at com.sun.xml.internal.stream.XMLEventReaderImpl.nextEvent(Unknown Source) at com.amazonaws.transform.StaxUnmarshallerContext.nextEvent(StaxUnmarshallerContext.java:153) ... (rest of lines omitted) I have double, triple, quadruple checked this XML for 'invisible characters' or non-UTF8 encoded characters, etc. I looked at it byte-by-byte in an array for byte-order-marks or something of that nature. Nothing; it passes every validation test I could throw at it. Even stranger, it happens if I use a Saxon-based parser as well -- but ONLY on GAE, it always works fine in my local environment. It makes it very hard to trace the code for problems when I can only run the debugger on an environment that works perfectly (I haven't found any good way to remotely debug on GAE). Nevertheless, using the primitive means I have, I've tried a million approaches including: XML with and without the prolog With and without newlines With and without the "encoding=" attribute in the prolog Both newline styles With and without the chunking information present in the HTTP stream And I've tried most of these in multiple combinations where it made sense they would interact -- nothing! I'm at my wit's end. Has anyone seen an issue like this before that can hopefully shed some light on it? Thanks!

  • WCF custom certificate validation with BasicHttpBinding

    - by Sprklnh2o
    I have a WCF application hosted on IIS 6 that needs to Have 2-way SSL authentication Validate client certificate content with some client host information Validate client certificate is issued by the valid subCA. I was able to do 1) successfully. I am trying to achieve 2) and 3) by following this - basically creating a class that inherits X509CertificateValidator and overriding the Validate method with my own validation implementation(step 2 and 3). I followed the MSDN instructions exactly however, it seem that the Validate method is not being called. I purposely throw a SecurityAccessDeniedException in the overidden Validate method and no exception is thrown when I tried to access the service via my browser. I can still access my website with any client certificate. I also read this thread but it didn't really help. Any help would be greatly appreciated! Here's my configuration: <system.serviceModel> <services> <service behaviorConfiguration="SimpleServiceBehavior" name="SampleNameSpace.SampleClass"> <endpoint address="" binding="basicHttpBinding" bindingConfiguration="NewBinding0" contract="SampleNameSpace.ISampleClass" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="SimpleServiceBehavior"> <serviceMetadata httpsGetEnabled="true" policyVersion="Default" /> <serviceCredentials> <clientCertificate> <authentication certificateValidationMode="Custom" customCertificateValidatorType="SampleNameSpace.MyX509CertificateValidator, SampleAssembly"/> </clientCertificate> </serviceCredentials> </behavior> </serviceBehaviors> </behaviors> <bindings> <basicHttpBinding> <binding name="NewBinding0"> <security mode="Transport"> <transport clientCredentialType="Certificate" /> </security> </binding> </basicHttpBinding> </bindings>

  • Ajax call to wcf windows service over ssl (https)

    - by bpatrick100
    I have a windows service which exposes an endpoint over http. Again this is a windows service (not a web service hosted in iis). I then call methods from this endpoint, using javascript/ajax. Everything works perfectly, and this the code I'm using in my windows service to create the endpoint: //Create host object WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri("http://192.168.0.100:1213")); //Add Https Endpoint WebHttpBinding binding = new WebHttpBinding(); webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); //Add MEX Behaivor and EndPoint ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); metadataBehavior.HttpGetEnabled = true; webServiceHost.Description.Behaviors.Add(metadataBehavior); webServiceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpBinding(), "mex"); webServiceHost.Open(); Now, my goal is to get this same model working over SSL (https not http). So, I have followed the guidance of several msdn pages, like the following: http://msdn.microsoft.com/en-us/library/ms733791(VS.100).aspx I have used makecert.exe to create a test cert called "bpCertTest". I have then used netsh.exe to configure my port (1213) with the test cert I created, all with no problem. Then, I've modified the endpoint code in my windows service to be able to work over https as follows: //Create host object WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri("https://192.168.0.100:1213")); //Add Https Endpoint WebHttpBinding binding = new WebHttpBinding(); binding.Security.Mode = WebHttpSecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate; webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); webServiceHost.Credentials.ServiceCertificate.SetCertificate("CN=bpCertTest", StoreLocation.LocalMachine, StoreName.My); //Add MEX Behaivor and EndPoint ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); metadataBehavior.HttpsGetEnabled = true; webServiceHost.Description.Behaviors.Add(metadataBehavior); webServiceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpsBinding(), "mex"); webServiceHost.Open(); The service creates the endpoint successfully, recognizes my cert in the SetCertificate() call, and the service starts up and running with success. Now, the problem is my javascript/ajax call cannot communicate with the service over https. I simply get some generic commication error (12031). So, as a test, I changed the port I was calling in the javascript to some other random port, and I get the same error - which tells me that I'm obviously not even reaching my service over https. I'm at a complete loss at this point, I feel like everything is in place, and I just can't see what the problem is. If anyone has experience in this scenario, please provide your insight and/or solution! Thanks!

  • How to consume PHP SOAP service using WCF

    - by mr.b
    I am new in web services so apologize me if I am making some cardinal mistake here, hehe. I have built SOAP service using PHP. Service is SOAP 1.2 compatible, and I have WSDL available. I have enabled sessions, so that I can track login status, etc. I don't need some super security here (ie message-level security), all I need is transport security (HTTPS), since this service will be used infrequently, and performances are not so much of an issue. I am having difficulties making it to work at all. C# throws some unclear exception ("Server returned an invalid SOAP Fault. Please see InnerException for more details.", which in turn says "Unbound prefix used in qualified name 'rpc:ProcedureNotPresent'."), but consuming service using PHP SOAP client behaves as expected (including session and all). So far, I have following code. note: due to amount of real code, I am posting minimal code configuration PHP SOAP server (using Zend Soap Server library), including class(es) exposed via service: <?php class Verification_LiteralDocumentProxy { protected $instance; public function __call($methodName, $args) { if ($this->instance === null) { $this->instance = new Verification(); } $result = call_user_func_array(array($this->instance, $methodName), $args[0]); return array($methodName.'Result' => $result); } } class Verification { private $guid = ''; private $hwid = ''; /** * Initialize connection * * @param string GUID * @param string HWID * @return bool */ public function Initialize($guid, $hwid) { $this->guid = $guid; $this->hwid = $hwid; return true; } /** * Closes session * * @return void */ public function Close() { // if session is working, $this->hwid and $this->guid // should contain non-empty values } } // start up session stuff $sess = Session::instance(); require_once 'Zend/Soap/Server.php'; $server = new Zend_Soap_Server('https://www.somesite.com/api?wsdl'); $server->setClass('Verification_LiteralDocumentProxy'); $server->setPersistence(SOAP_PERSISTENCE_SESSION); $server->handle(); WSDL: <definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="https://www.somesite.com/api" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" name="Verification" targetNamespace="https://www.somesite.com/api"> <types> <xsd:schema targetNamespace="https://www.somesite.com/api"> <xsd:element name="Initialize"> <xsd:complexType> <xsd:sequence> <xsd:element name="guid" type="xsd:string"/> <xsd:element name="hwid" type="xsd:string"/> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:element name="InitializeResponse"> <xsd:complexType> <xsd:sequence> <xsd:element name="InitializeResult" type="xsd:boolean"/> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:element name="Close"> <xsd:complexType/> </xsd:element> </xsd:schema> </types> <portType name="VerificationPort"> <operation name="Initialize"> <documentation> Initializes connection with server</documentation> <input message="tns:InitializeIn"/> <output message="tns:InitializeOut"/> </operation> <operation name="Close"> <documentation> Closes session between client and server</documentation> <input message="tns:CloseIn"/> </operation> </portType> <binding name="VerificationBinding" type="tns:VerificationPort"> <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="Initialize"> <soap:operation soapAction="https://www.somesite.com/api#Initialize"/> <input> <soap:body use="literal"/> </input> <output> <soap:body use="literal"/> </output> </operation> <operation name="Close"> <soap:operation soapAction="https://www.somesite.com/api#Close"/> <input> <soap:body use="literal"/> </input> <output> <soap:body use="literal"/> </output> </operation> </binding> <service name="VerificationService"> <port name="VerificationPort" binding="tns:VerificationBinding"> <soap:address location="https://www.somesite.com/api"/> </port> </service> <message name="InitializeIn"> <part name="parameters" element="tns:Initialize"/> </message> <message name="InitializeOut"> <part name="parameters" element="tns:InitializeResponse"/> </message> <message name="CloseIn"> <part name="parameters" element="tns:Close"/> </message> </definitions> And finally, WCF C# consumer code: [ServiceContract(SessionMode = SessionMode.Required)] public interface IVerification { [OperationContract(Action = "Initialize", IsInitiating = true)] bool Initialize(string guid, string hwid); [OperationContract(Action = "Close", IsInitiating = false, IsTerminating = true)] void Close(); } class Program { static void Main(string[] args) { WSHttpBinding whb = new WSHttpBinding(SecurityMode.Transport, true); ChannelFactory<IVerification> cf = new ChannelFactory<IVerification>( whb, "https://www.somesite.com/api"); IVerification client = cf.CreateChannel(); Console.WriteLine(client.Initialize("123451515", "15498518").ToString()); client.Close(); } } Any ideas? What am I doing wrong here? Thanks!

  • Streaming a webcam from Silverlight 4 (Beta)

    - by Ken Smith
    The new webcam stuff in Silverlight 4 is darned cool. By exposing it as a brush, it allows scenarios that are way beyond anything that Flash has. At the same time, accessing the webcam locally seems like it's only half the story. Nobody buys a webcam so they can take pictures of themselves and make funny faces out of them. They buy a webcam because they want other people to see the resulting video stream, i.e., they want to stream that video out to the Internet, a lay Skype or any of the dozens of other video chat sites/applications. And so far, I haven't figured out how to do that with It turns out that it's pretty simple to get a hold of the raw (Format32bppArgb formatted) bytestream, as demonstrated here. But unless we want to transmit that raw bytestream to a server (which would chew up way too much bandwidth), we need to encode that in some fashion. And that's more complicated. MS has implemented several codecs in Silverlight, but so far as I can tell, they're all focused on decoding a video stream, not encoding it in the first place. And that's apart from the fact that I can't figure out how to get direct access to, say, the H.264 codec in the first place. There are a ton of open-source codecs (for instance, in the ffmpeg project here), but they're all written in C, and they don't look easy to port to C#. Unless translating 10000+ lines of code that look like this is your idea of fun :-) const int b_xy= h->mb2b_xy[left_xy[i]] + 3; const int b8_xy= h->mb2b8_xy[left_xy[i]] + 1; *(uint32_t*)h->mv_cache[list][cache_idx ]= *(uint32_t*)s->current_picture.motion_val[list][b_xy + h->b_stride*left_block[0+i*2]]; *(uint32_t*)h->mv_cache[list][cache_idx+8]= *(uint32_t*)s->current_picture.motion_val[list][b_xy + h->b_stride*left_block[1+i*2]]; h->ref_cache[list][cache_idx ]= s->current_picture.ref_index[list][b8_xy + h->b8_stride*(left_block[0+i*2]>>1)]; h->ref_cache[list][cache_idx+8]= s->current_picture.ref_index[list][b8_xy + h->b8_stride*(left_block[1+i*2]>>1)]; The mooncodecs folder within the Mono project (here) has several audio codecs in C# (ADPCM and Ogg Vorbis), and one video codec (Dirac), but they all seem to implement just the decode portion of their respective formats, as do the java implementations from which they were ported. I found a C# codec for Ogg Theora (csTheora, http://www.wreckedgames.com/forum/index.php?topic=1053.0), but again, it's decode only, as is the jheora codec on which it's based. Of course, it would presumably be easier to port a codec from Java than from C or C++, but the only java video codecs that I found were decode-only (such as jheora, or jirac). So I'm kinda back at square one. It looks like our options for hooking up a webcam (or microphone) through Silverlight to the Internet are: (1) Wait for Microsoft to provide some guidance on this; (2) Spend the brain cycles porting one of the C or C++ codecs over to Silverlight-compatible C#; (3) Send the raw, uncompressed bytestream up to a server (or perhaps compressed slightly with something like zlib), and then encode it server-side; or (4) Wait for someone smarter than me to figure this out and provide a solution. Does anybody else have any better guidance? Have I missed something that's just blindingly obvious to everyone else? (For instance, does Silverlight 4 somewhere have some classes I've missed that take care of this?)

  • Asynchronous COMET query with Tornado and Prototype

    - by grundic
    Hello everyone. I'm trying to write simple web application using Tornado and JS Prototype library. So, the client can execute long running job on server. I wish, that this job runs Asynchronously - so that others clients could view page and do some stuff there. Here what i've got: #!/usr/bin/env/ pytthon import tornado.httpserver import tornado.ioloop import tornado.options import tornado.web from tornado.options import define, options import os import string from time import sleep from datetime import datetime define("port", default=8888, help="run on the given port", type=int) class MainHandler(tornado.web.RequestHandler): def get(self): self.render("templates/index.html", title="::Log watcher::", c_time=datetime.now()) class LongHandler(tornado.web.RequestHandler): @tornado.web.asynchronous def get(self): self.wait_for_smth(callback=self.async_callback(self.on_finish)) print("Exiting from async.") return def wait_for_smth(self, callback): t=0 while (t < 10): print "Sleeping 2 second, t={0}".format(t) sleep(2) t += 1 callback() def on_finish(self): print ("inside finish") self.write("Long running job complete") self.finish() def main(): tornado.options.parse_command_line() settings = { "static_path": os.path.join(os.path.dirname(__file__), "static"), } application = tornado.web.Application([ (r"/", MainHandler), (r"/longPolling", LongHandler) ], **settings ) http_server = tornado.httpserver.HTTPServer(application) http_server.listen(options.port) tornado.ioloop.IOLoop.instance().start() if __name__ == "__main__": main() This is server part. It has main view (shows little greeting, current server time and url for ajax query, that executes long running job. If you press a button, a long running job executes. And server hangs :( I can't view no pages, while this job is running. Here is template page: <html> <head> <title>{{ title }}</title> <script type="text/javascript" language="JavaScript" src="{{ static_url("js/prototype.js")}}"></script> <script type='text/javascript' language='JavaScript'> offset=0 last_read=0 function test(){ new Ajax.Request("http://172.22.22.22:8888/longPolling", { method:"get", asynchronous:true, onSuccess: function (transport){ alert(transport.responseText); } }) } </script> </head> <body> Current time is {{c_time}} <br> <input type="button" value="Test" onclick="test();"/> </body> </html> what am I doing wrong?

  • Why is "wsdl" namespace interjected into action name when using savon for ruby soap communication?

    - by Nick Gorbikoff
    I'm trying to access a SOAP service i don't control. One of the actions is called ProcessMessage. I follow example and generate a SOAP request, but I get an error back saying that the action doesn't exist. I traced the problem to the way the body of the envelope is generated. <env:Envelope ... "> <env:Header> <wsse:Security ... "> <wsse:UsernameToken ..."> <wsse:Username>USER</wsse:Username> <wsse:Nonce>658e702d5feff1777a6c741847239eb5d6d86e48</wsse:Nonce> <wsu:Created>2010-02-18T02:05:25Z</wsu:Created> <wsse:Password ... >password</wsse:Password> </wsse:UsernameToken> </wsse:Security> </env:Header> <env:Body> <wsdl:ProcessMessage> <payload> ...... </payload> </wsdl:ProcessMessage> </env:Body> </env:Envelope> That ProcessMessage tag should be : <ProcessMessage xmlns="http://www.starstandards.org/webservices/2005/10/transport"> That's what it is when it is generated by the sample java app, and it works. That tag is the only difference between what my ruby app generates and the sample java app. Is there any way to get rid of the "wsdl:" namesaplce in front of that one tag and add an attribute like that. Barring that, is there a way to make force the action to be not to be generated by just passed as a string like the rest of the body? Here is my code. require 'rubygems' require 'savon' client = Savon::Client.new "https://gmservices.pp.gm.com/ProcessMessage?wsdl" response = client.process_message! do | soap, wsse | wsse.username = "USER" wsse.password = "password" soap.namespace = "http://www.starstandards.org/webservices/2005/10/transport" #makes no difference soap.action = "ProcessMessage" #makes no difference soap.input = "ProcessMessage" #makes no difference #my body at this point is jsut one big xml string soap.body = "<payload>...</payload>" # putting <ProccessMessage> tag here doesn't help as it just creates a duplicate tag in the body, since Savon keeps interjecting <wsdl:ProcessMessage> tag. end Thank you P.S.: I tried handsoap but it doesn't support httpS and is confusing, and I tried soap4r but but it'even more confusing than handsoap.

  • JpegBitmapEncoder.Save() throws exception when writing image with metadata to MemoryStream

    - by Dmitry
    I am trying to set up metadata on JPG image what does not have it. You can't use in-place writer (InPlaceBitmapMetadataWriter) in this case, cuz there is no place for metadata in image. If I use FileStream as output - everything works fine. But if I try to use MemoryStream as output - JpegBitmapEncoder.Save() throws an exception (Exception from HRESULT: 0xC0000005). After some investigation I also found out what encoder can save image to memory stream if I supply null instead of metadata. I've made a very simplified and short example what reproduces the problem: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Drawing; using System.Drawing.Imaging; using System.Windows.Media.Imaging; namespace JpegSaveTest { class Program { public static JpegBitmapEncoder SetUpMetadataOnStream(Stream src, string title) { uint padding = 2048; BitmapDecoder original; BitmapFrame framecopy, newframe; BitmapMetadata metadata; JpegBitmapEncoder output = new JpegBitmapEncoder(); src.Seek(0, SeekOrigin.Begin); original = JpegBitmapDecoder.Create(src, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad); if (original.Frames[0] != null) { framecopy = (BitmapFrame)original.Frames[0].Clone(); if (original.Frames[0].Metadata != null) metadata = original.Frames[0].Metadata.Clone() as BitmapMetadata; else metadata = new BitmapMetadata("jpeg"); metadata.SetQuery("/app1/ifd/PaddingSchema:Padding", padding); metadata.SetQuery("/app1/ifd/exif/PaddingSchema:Padding", padding); metadata.SetQuery("/xmp/PaddingSchema:Padding", padding); metadata.SetQuery("System.Title", title); newframe = BitmapFrame.Create(framecopy, framecopy.Thumbnail, metadata, original.Frames[0].ColorContexts); output.Frames.Add(newframe); } else { Exception ex = new Exception("Image contains no frames."); throw ex; } return output; } public static MemoryStream SetTagsInMemory(string sfname, string title) { Stream src, dst; JpegBitmapEncoder output; src = File.Open(sfname, FileMode.Open, FileAccess.Read, FileShare.Read); output = SetUpMetadataOnStream(src, title); dst = new MemoryStream(); output.Save(dst); src.Close(); return (MemoryStream)dst; } static void Main(string[] args) { string filename = "Z:\\dotnet\\gnom4.jpg"; MemoryStream s; s = SetTagsInMemory(filename, "test title"); } } } It is simple console application. To run it, replace filename variable content with path to any .jpg file without metadata (or use mine). Ofc I can just save image to temporary file first, close it, then open and copy to MemoryStream, but its too dirty and slow workaround. Any ideas about getting this working are welcome :)
