  • What is a good alternative to the WPF WebBrowser Control?

    - by VoidDweller
    I have an MDI WPF app that I need to add web content to. At first, great it looks like I have 2 options built into the framework the Frame control and the WebBrowser control. Given that this is an MDI app it doesn't take long to discover that neither of these will work. The WPF WebBrowser control wraps up the IE WebBrowser ActiveX Control which uses the Win32 graphics pipeline. The "Airspace" issue pretty much sums this up as "Sorry, the layouts will not play nice together". Yes, I have thought about taking snapshots of the web content rendering these and mapping the mouse and keyboard events back to the browser control, but I can't afford the performance penalty and I really don't have time to write and thoroughly test it. I have looked for third party controls, but so far I have only found Chris Cavanagh's WPF Chromium Web Browser control. Which wraps up Awesomium 1.5. Together these are very cool, they play nice with the WPF layouts. But they do not meet my performance requirements. They are VERY HEAVY on memory consumption and not to friendly with CPU usage either. Not to mention still quite buggy. I'll elaborate if you are interested. So, do any of you know of a stable performant WPF web browser control? Thanks.

  • WCF GZip Compression Request/Response Processing

    - by IanT8
    How do I get a WCF client to process server responses which have been GZipped or Deflated by IIS? On IIS, I've followed the instructions here on how to make IIS 6 gzip all responses (where the request contained "Accept-Encoding: gzip, deflate") emitted by .svc wcf services. On the client, I've followed the instructions here and here on how to inject this header into the web request: "Accept-Encoding: gzip, deflate". Fiddler2 shows the response is binary and not plain old Xml. The client crashes with an exception which basically says there's no Xml header, which ofcourse is true. In my IClientMessageInspector, the app crashes before AfterReceiveReply is called. Some further notes: (1) I can't change the WCF service or client as they are supplied by a 3rd party. I can however attach behaviors and/or message inspectors via configuration if this is the right direction to take. (2) I don't want to compress/uncompress just the soap body, but the entire message. Any ideas/solutions? * SOLVED * It was not possible to write a WCF extension to achieve these goals. Instead I followed this CodeProject article which advocate a helper class: public class CompressibleHttpRequestCreator : IWebRequestCreate { public CompressibleHttpRequestCreator() { } WebRequest IWebRequestCreate.Create(Uri uri) { HttpWebRequest httpWebRequest = Activator.CreateInstance(typeof(HttpWebRequest), BindingFlags.CreateInstance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance, null, new object[] { uri, null }, null) as HttpWebRequest; if (httpWebRequest == null) { return null; } httpWebRequest.AutomaticDecompression =DecompressionMethods.GZip | DecompressionMethods.Deflate; return httpWebRequest; } } and also, an addition to the application configuration file: <configuration> <system.net> <webRequestModules> <remove prefix="http:"/> <add prefix="http:" type="Pajocomo.Net.CompressibleHttpRequestCreator, Pajocomo" /> </webRequestModules> </system.net> </configuration> What seems to be happening is that WCF eventually asks some factory or other deep down in system.net to provide an HttpWebRequest instance, and we provide the helper that will be asked to create the required instance. In the WCF client configuration file, a simple basicHttpBinding is all that is required, without the need for any custom extensions. When the application runs, the client Http request contains the header "Accept-Encoding: gzip, deflate", the server returns a gzipped web response, and the client transparently decompresses the http response before handing it over to WCF. When I tried to apply this technique to Web Services I found that it did NOT work. Although the helper class was executed in the same was as when used by the WCF client, the http request did not contain the "Accept-Encoding: ..." header. To make this work for Web Services, I had to edit the Web Proxy class, and add this method: protected override System.Net.WebRequest GetWebRequest(Uri uri) { System.Net.HttpWebRequest rq = (System.Net.HttpWebRequest)base.GetWebRequest(uri); rq.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate; return rq; } Note that it did not matter whether the CompressibleHttpRequestCreator and block from the application config file were present or not. For web services, only overriding GetWebRequest in the Web Service Proxy worked.

  • Is there any gmap's api function to concatenate address string from AddressDetails structure?

    - by Vadim
    Hello! I’am using Google Map’s GClientGeocoder for reversing map coordinates into string address. Exactly as shown in google’s example here http://code.google.com/apis/ajax/playground/?exp=maps#geocoding_reverse But, I would like to extract LocalityName (place.AddressDetails.Country.AdministrativeArea.Locality.LocalityName) from place.address. The straight way will be join all AddressDetails elements, excluding LocalityName. However order of the structure elements in final string representation is depends from geographical location. For example: Order for Australia city: ThoroughfareName + “, ” + LocalityName + “ ” + AdministrativeAreaName + “ ” + PostalCodeNumber + “, ” + CountryName Order for Russian city: CountryName + “, ” + PostalCodeNumber + “, ” + LocalityName + “, ” +ThoroughfareName Moreover PostalCodeNumber was not supplied in AddressDetails for the last example. Please, help!

  • Why SetUnhandledExceptionFilter cannot capture some exception but AddVectoredExceptionHandler can do

    - by wrongite
    I have experienced a problem that the function I passed to the SetUnhandledExceptionFilter didn't get called when the exception code c0000374 raising. But it works fine with the exception code c0000005. Then I tried to use the AddVectoredExceptionHandler instead, and it didn't have the problem, the handler function get called correctly. Is it the API bug? Can I use AddVectoredExceptionHandler instead of SetUnhandledExceptionFilter everywhere? The both functions work correctly with // Exception code c0000005 int* p1 = NULL; *p1 = 99; Only AddVectoredExceptionHandler can capture this exception. // Exception code c0000374 int* p2 = new int; delete p2; delete p2; Test program. #include <tchar.h> #include <fstream> #include <Windows.h> LONG WINAPI VectoredExceptionHandler(PEXCEPTION_POINTERS pExceptionInfo) { std::ofstream f; f.open("VectoredExceptionHandler.txt", std::ios::out | std::ios::trunc); f << std::hex << pExceptionInfo->ExceptionRecord->ExceptionCode << std::endl; f.close(); return EXCEPTION_CONTINUE_SEARCH; } LONG WINAPI TopLevelExceptionHandler(PEXCEPTION_POINTERS pExceptionInfo) { std::ofstream f; f.open("TopLevelExceptionHandler.txt", std::ios::out | std::ios::trunc); f << std::hex << pExceptionInfo->ExceptionRecord->ExceptionCode << std::endl; f.close(); return EXCEPTION_CONTINUE_SEARCH; } int _tmain(int argc, _TCHAR* argv[]) { AddVectoredExceptionHandler(1, VectoredExceptionHandler); SetUnhandledExceptionFilter(TopLevelExceptionHandler); // Exception code c0000374 int* p2 = new int; delete p2; delete p2; // Exception code c0000005 int* p1 = NULL; *p1 = 99; return 0; }

  • SSH / SFTP connection issue using Tamir.SharpSsh

    - by jinsungy
    This is my code to connect and send a file to a remote SFTP server. public static void SendDocument(string fileName, string host, string remoteFile, string user, string password) { Scp scp = new Scp(); scp.OnConnecting += new FileTansferEvent(scp_OnConnecting); scp.OnStart += new FileTansferEvent(scp_OnProgress); scp.OnEnd += new FileTansferEvent(scp_OnEnd); scp.OnProgress += new FileTansferEvent(scp_OnProgress); try { scp.To(fileName, host, remoteFile, user, password); } catch (Exception e) { throw e; } } I can successfully connect, send and receive files using CoreFTP. Thus, the issue is not with the server. When I run the above code, the process seems to stop at the scp.To method. It just hangs indefinitely. Anyone know what might my problem be? Maybe it has something to do with adding the key to the a SSH Cache? If so, how would I go about this? EDIT: I inspected the packets using wireshark and discovered that my computer is not executing the Diffie-Hellman Key Exchange Init. This must be the issue. EDIT: I ended up using the following code. Note, the StrictHostKeyChecking was turned off to make things easier. JSch jsch = new JSch(); jsch.setKnownHosts(host); Session session = jsch.getSession(user, host, 22); session.setPassword(password); System.Collections.Hashtable hashConfig = new System.Collections.Hashtable(); hashConfig.Add("StrictHostKeyChecking", "no"); session.setConfig(hashConfig); try { session.connect(); Channel channel = session.openChannel("sftp"); channel.connect(); ChannelSftp c = (ChannelSftp)channel; c.put(fileName, remoteFile); c.exit(); } catch (Exception e) { throw e; } Thanks.

  • Using telerik radGrid - how to set the Date format for autogenerated column in edit mode

    - by Mark Breen
    Hello All, Using VS2008, and Telerik radGrid version 2010.1.519.35 I have a about 50 DNN modules using telerik radgrid and I need to display my dates in dd/mm/yy format. It is possible to do this easily in view mode, but when I switch to edit mode, it is more of a struggle. I can write a snippit of code to reformat the displayed date values to dd/mm/yy, but for inserts the user must enter mm/dd/yy. IOW, I need to change the culture of the form to en-GB culture. In my DotnetNuke App, I have made a change to the web.config, but it still assumes en-US format. I am not sure whether I need to set this at web.config level, page level or at the column within the control. I am struggling with this for a month or more and any help would be appriciated, thanks Mark Breen Ireland BMW R80GS 1987

  • How can i add a checkbox for optional files during install? (innosetup)

    - by Globulorozzo
    i'm trying to make a custom checkbox in my custom page (because is a one page installer), is needed only a checkbox without dialogs or anything, the installer that i'm trying to compile is very linear and simple. i want to bind "FILE3.EXE" on a checkbox in this way: if checkbox is checked copy the file (FILE3.EXE) in DestDir, otherwise if checkbox is unchecked skip the file (FILE3.EXE) during installation.

  • How to Remove Header in LaTex

    Hi, I would like to not show the name of each chapter on the header of its each page. I also like to have nothing in the headers for abstract, acknowledgement, table of content, list of figures and list of tables.

  • Android RelativeLayout fill_parent unexpected behavior in a ListView with varying row heights

    - by Jameel Al-Aziz
    I'm currently working on a small update to a project and I'm having an issue with Relative_Layout and fill_parent in a list view. I'm trying to insert a divider between two sections in each row, much like the divider in the call log of the default dialer. I checked out the Android source code to see how they did it, but I encountered a problem when replicating their solution. To start, here is my row item layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:padding="10dip" android:layout_height="fill_parent" android:maxHeight="64dip" android:minHeight="?android:attr/listPreferredItemHeight"> <ImageView android:id="@+id/infoimage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:clickable="true" android:src="@drawable/info_icon_big" android:layout_alignParentRight="true" android:layout_centerVertical="true"/> <View android:id="@+id/divider" android:background="@drawable/divider_vertical_dark" android:layout_marginLeft="11dip" android:layout_toLeftOf="@+id/infoimage" android:layout_width="1px" android:layout_height="fill_parent" android:layout_marginTop="5dip" android:layout_marginBottom="5dip" android:layout_marginRight="4dip"/> <TextView android:id="@+id/TextView01" android:textAppearance="?android:attr/textAppearanceLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_toRightOf="@+id/ImageView01" android:layout_toLeftOf="@+id/divider" android:gravity="left|center_vertical" android:layout_marginLeft="4dip" android:layout_marginRight="4dip"/> <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:background="@drawable/bborder" android:layout_centerVertical="true"/> </RelativeLayout> The issue I'm facing is that each row has a thumbnail of varying height (ImageView01). If I set the RelativeLayout's layout_height property to fill_parent, the divider does not scale vertically to fill the row (it just remains a 1px dot). If I set layout_height to "?android:attr/listPreferredItemHeight", the divider fills the row, but the thumbnails shrink. I've done some debugging in the getView() method of the adapter, and it seems that the divider's height is not being set properly once the row has it's proper height. Here is a portion of the getView() method: public View getView(int position, View view, ViewGroup parent) { if (view == null) { view = inflater.inflate(R.layout.tag_list_item, parent, false); } The rest of the method simply sets the appropriate text and images for the row. Also, I create the inflater object in the adapter's constructor with: inflater = LayoutInflater.from(context); Am I missing something essential? Or does fill_parent just not work with dynamic heights?

  • Encryption is hard: AES encryption to Hex

    - by Rob Cameron
    So, I've got an app at work that encrypts a string using ColdFusion. ColdFusion's bulit-in encryption helpers make it pretty simple: encrypt('string_to_encrypt','key','AES','HEX') What I'm trying to do is use Ruby to create the same encrypted string as this ColdFusion script is creating. Unfortunately encryption is the most confusing computer science subject known to man. I found a couple helper methods that use the openssl library and give you a really simple encryption/decryption method. Here's the resulting string: "\370\354D\020\357A\227\377\261G\333\314\204\361\277\250" Which looks unicode-ish to me. I've tried several libraries to convert this to hex but they all say it contains invalid characters. Trying to unpack it results in this: string = "\370\354D\020\357A\227\377\261G\333\314\204\361\277\250" string.unpack('U') ArgumentError: malformed UTF-8 character from (irb):19:in `unpack' from (irb):19 At the end of the day it's supposed to look like this (the output of the ColdFusion encrypt method): F8E91A689565ED24541D2A0109F201EF Of course that's assuming that all the padding, initialization vectors, salts, cypher types and a million other possible differences all line up. Here's the simple script I'm using to encrypt/decrypt: def aes(m,k,t) (aes = OpenSSL::Cipher::Cipher.new('aes-256-cbc').send(m)).key = Digest::SHA256.digest(k) aes.update(t) << aes.final end def encrypt(key, text) aes(:encrypt, key, text) end def decrypt(key, text) aes(:decrypt, key, text) end Any help? Maybe just a simple option I can pass to OpenSSL::Cipher::Cipher that will tell it to hex-encode the final string?

  • XCode Build Parse Error 'Unexpected @ in Program'

    - by Grymjack
    I'm following a tutorial for creating an animation using Xcode Version 4.5.2 in Mountain Lion 10.8.2. When trying to build the code below, I get a Parse Error Unexpected '@' in program showing up for the 'hopAnimation=' line. While searching, I have found examples that build simple animations in a different way, but nothing that seems to address this particular problem. I'm a noob to XCode programming and if anyone could help me correct the syntax, I would highly appreciate it. I would also like to thank all the contributors to stackflow for making this such a valuable resource. Searching for the answers to most of my prior questions always seemed to have you guys at the top of the results list. ViewController.m - (void)viewDidLoad { // load all the frames of our animation into an array NSArray *hopAnimation; hopAnimation=[[NSArray alloc] arrayWithObjects: [UIImage imageNamed:@”frame-1.png”], [UIImage imageNamed:@”frame-2.png”], [UIImage imageNamed:@”frame-3.png”], [UIImage imageNamed:@”frame-4.png”], [UIImage imageNamed:@”frame-5.png”], [UIImage imageNamed:@”frame-6.png”], [UIImage imageNamed:@”frame-7.png”], [UIImage imageNamed:@”frame-8.png”], [UIImage imageNamed:@”frame-9.png”], [UIImage imageNamed:@”frame-10.png”], [UIImage imageNamed:@”frame-11.png”], [UIImage imageNamed:@”frame-12.png”], [UIImage imageNamed:@”frame-13.png”], [UIImage imageNamed:@”frame-14.png”], [UIImage imageNamed:@”frame-15.png”], [UIImage imageNamed:@”frame-16.png”], [UIImage imageNamed:@”frame-17.png”], [UIImage imageNamed:@”frame-18.png”], [UIImage imageNamed:@”frame-19.png”], [UIImage imageNamed:@”frame-20.png”],nil]; self.bunnyView1.animationImages=hopAnimation; self.bunnyView2.animationImages=hopAnimation; self.bunnyView3.animationImages=hopAnimation; self.bunnyView4.animationImages=hopAnimation; self.bunnyView5.animationImages=hopAnimation; self.bunnyView1.animationDuration=1; self.bunnyView2.animationDuration=1; self.bunnyView3.animationDuration=1; self.bunnyView4.animationDuration=1; self.bunnyView5.animationDuration=1; [super viewDidLoad]; }

  • UISplitViewController in a TabBar ( UITabBarController )?

    - by Madhup
    Hi all, I am in kind of situation that I need to start with a tab based application and in that I need a split view for one or more tabs. But it seems that split view controller object can not be added to the tabbarController. (Although tabbar object can be added to the splitviewcontroller). The problem can be seen otherways: I have a full screen in the left part I have a table view when any row is selected in the table a popover should come out pointing that row. Now when any row in the popover is selected the rows in this popover comes to the left under the selected row (only this row would be visible) and another popover comes out from the selected row. (Breadcrumb navigation type) I think I am clear in what I explained. So guys any ideas or work arounds? Please let me know if I am not clear in my question. Thanks, Madhup

    I am using an Ajax.ActionLink to call an Action in a Controller, nothing special there. I want to pass two parameters to the Action. Is this possible using an Ajax.ActionLink? I thought that it would just be a matter of including multiple values in the AjaxOptions: <%= Ajax.ActionLink("Link Text", "ActionName", "ControllerName", new { firstParameter = firstValueToPass, secondParameter = secondValueToPass }, new AjaxOptions{ UpdateTargetId = "updateTargetId"} )%> Is it possible to pass multiple parameters? Where is a good place to learn more about the AjaxOptions?

  • 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; } } }

  • Use MTOM/streaming from C# calling a webservice in java exposed via jaxws

    - by raticulin
    We have this webservice created with jax-ws @WebService(name = "Mywebser", targetNamespace = "http://namespace") @MTOM(threshold = 2048) @SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED) public class Mywebser { @WebMethod(operationName = "doStreaming", action = "urn:doStreaming") @WebResult(name = "return") public ResultInfo doStreaming(String username, String pwd, @XmlMimeType("application/octet-stream") DataHandler data, boolean overw){ ... } } The generated client side looks like this: @WebMethod(action = "urn:doStreaming") @WebResult(targetNamespace = "") @RequestWrapper(localName = "doStreaming", targetNamespace = "http://namespace", className = "com.mypack.client.doStreaming") @ResponseWrapper(localName = "doStreamingResponse", targetNamespace = "http://namespace", className = "com.mypack.client.doStreamingResponse") public ResultInfo doStreaming( @WebParam(name = "arg0", targetNamespace = "") String arg0, @WebParam(name = "arg1", targetNamespace = "") String arg1, @WebParam(name = "arg2", targetNamespace = "") DataHandler arg2, @WebParam(name = "arg3", targetNamespace = "") boolean arg3); By using it this way it uses streaming properly (verified we can pass an argument of 80mb when the jvm had less allowed. MywebserService serv = ...; Mywebser wso = serv.getMywebserPort(new MTOMFeature()); Map<String, Object> ctxt = ((BindingProvider) wso).getRequestContext(); ctxt.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192); DataHandler dataHandler = new DataHandler(new FileDataSource("c:\\temp\\A.dat")); arcres = wso.doStreaming("a", "b", dataHandler, true); We generate a clienet for .net, with VS2008, using "Add Web Reference", we get this C# code: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("urn:doStreaming",RequestNamespace="http://namespace",ResponseNamespace="http://namespace",Use=System.Web.Services.Description.SoapBindingUse.Literal,ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] [return: System.Xml.Serialization.XmlElementAttribute("return",Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] public ResultInfo doStreaming( [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string arg0, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string arg1, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified,DataType="base64Binary")] byte[] arg2, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] bool arg3) Apparently this is not using streaming? The type base64Binary of arg2 seems not the right one? In java it's a DataHandler. By testing it with low memory on the java side we can see it is not using streaming as it fails with OOM. Does someone knows if this is possible, and if so how? Our environment: server: jdk1.6, jaxws 2.1.7 client: C# 2.0, visual studio 2008

  • WPF ListBoxItem double-click?

    - by David Veeneman
    The WPF ListBox doesn't have a DoubleClick event, at least not as far as I can tell. Is there a workaround for this issue that would let me double-click on an item to have an event handler do something with it? Thanks for your help.

  • Sharepoint 2010 Managed Metadata - unable to get Term from TermSet

    - by Blakomen
    Hi guys, Having a really aggravating problem using Managed Metadata in SP2010 where I can get a Taxonomy Session, Term Store and Term set fine, but when I try to retrieve a term from the term set, I get a TermStoreOperationException which says that it "failed to read from or write to database". Does anyone have any idea as to why I can get the Term Set but not the terms? I can't quite understand why when they all reside in the same database I can get the set but not the terms within it. The code I'm using is below: TaxonomySession txSession = new TaxonomySession(site, true); TermStore termStore = txSession.DefaultSiteCollectionTermStore; TermSet termSet = termStore.GetTermSet(txField.TermSetId); TermCollection termCollection = termSet.GetTerms(xnField.InnerText.Trim(), true); //exception thrown on this line. Any ideas or insight or solutions would be really appreciated. Thanks heaps!

  • Jquery JQGrid trigger reloadGrid

    - by JK
    I'm using a jqgrid to display the results of a search. When the search button is clicked it does this: $("#Search").jqGrid('setGridParam', { url: url }).trigger("reloadGrid"); Where url contains the search params eg: var url ="/search?first=joe&last=smith" The web server is receiving this url and responding appropriately. But on the client side it throws this error in jqgrid.min.js line 21: Syntax error: }); b.fn.jqGrid = function(f) { What can I do to fix this? I'm using jqgrid sucessfully in many other places, but this is the only one where I'm changing the url and reloading.

  • No native symbols in symbol file

    - by Martin
    I am trying to remote debug a Windows Form app with VS2008. Attaching to process works fine (Remote (Native only with no authentication)), but when I open the modules window and try to load symbols I get No native symbols in symbol file. I realise it has something to do with how the app was build but cannot figure out what ?
