  • Me As Child Type In General Function

    - by Steven
    I have a MustInherit Parent class with two Child classes which Inherit from the Parent. How can I use (or Cast) Me in a Parent function as the the child type of that instance? EDIT: My actual goal is to be able to serialize (BinaryFormatter.Serialize(Stream, Object)) either of my child classes. However, "repeating the code" in each child "seems" wrong. EDIT2: This is my Serialize function. Where should I implement this function? Copying and pasting to each child doesn't seem right, but casting the parent to a child doesn't seem right either. Public Function Serialize() As Byte() Dim bFmt As New BinaryFormatter() Dim mStr As New MemoryStream() bFmt.Serialize(mStr, Me) Return mStr.ToArray() End Function

  • In C# how can I serialize a List<int> to a byte[] in order to store it in a DB field?

    - by Matt
    In C# how can I serialize a List to a byte[] in order to store it in a DB field? I know how to serialize to a file on the disk, but how do I just serialize to a variable? Here is how I serialized to the disk: List<int> l = IenumerableofInts.ToList(); Stream s = File.OpenWrite("file.bin"); BinaryFormatter bf = new BinaryFormatter(); bf.Serialize(s, lR); s.Close(); I'm sure it's much the same but I just can't wrap my head around it.

  • Debugger Visualizer, ElementHost, and Edit and Continue problems

    - by Frank Fella
    I recently wrote a custom Debugger Visualizer for Visual Studio 2008 for one of the custom types in my application. The UI for the visualizer is written in WPF and is hosted in an element host and shown using the IDialogVisualizerService windowService object. Everything works great, and my visualizer loads and shows the relevant information, but if try to "edit and continue" in my application after loading the visualizer, Visual Studio crashes with no useful error message. In trying to debug this I removed almost all of my code from the solution to the point where I was only serializing a string with the ObjectSource and displaying just an empty element host and I still get the crash on edit and continue. If I remove the element host and show a WinForms control or form there is no crash. Here is the Visualizer code: using System; using System.Drawing; using System.IO; using System.Runtime.Serialization.Formatters.Binary; using System.Windows.Forms; using System.Windows.Forms.Integration; using Microsoft.VisualStudio.DebuggerVisualizers; using ObjectVisualizerShared; using ObjectVisualizerUI; namespace ObjectVisualizer { public class Visualizer : DialogDebuggerVisualizer { protected override void Show(IDialogVisualizerService windowService, IVisualizerObjectProvider objectProvider) { try { Stream stream = objectProvider.GetData(); if (stream.Length > 0) { BinaryFormatter formatter = new BinaryFormatter(); VisualizerNode node = (VisualizerNode)formatter.Deserialize(stream); if (node != null) { VisualizerWindow window = new VisualizerWindow(node); ElementHost host = new ElementHost(); host.Child = window; host.Dock = DockStyle.Fill; host.Size = new Size(800, 600); windowService.ShowDialog(host); } } } catch (Exception ex) { MessageBox.Show(string.Format("Error!\n{0}", ex), "Object Visualizer"); } } } } Any ideas?

  • DeSerialization doesn't work though i Implement GetObjectData method and Constructor

    - by Punit Singhi
    Hi, I have a static generic dictionary in a class. As static memeber cannot serialized so i have implented ISerializable interface and method GetObjectData to serialize. I have a constructor which will also accept SerializationInfo and StreamingContext to deserliaze the dictionay. Now when i try to serialize and deserialize , it always return 1(thoug i added 2 entries). please find the pseduo code- [Serializable] public class MyClass : ISerializable { internal static Dictionary<long, string> dict = new Dictionary<long,string>(); public void GetObjectData(SerializationInfo info, StreamingContext context) { info.AddValue("static.dic", MyClass1.dict, typeof(Dictionary<long, string>)); } public MyClass(SerializationInfo info, StreamingContext context) { MyClass.dict= (Dictionary<long, string>)info.GetValue("static.dic", typeof(Dictionary<long, string>)); } public void Add() { dict.Add(21, "11"); } public MyClass() { dict.Add(21, "11"); } } public class MyClass { MyClass myClass = new MyClass(); public static void Main() { myClass.Add(); FileStream fileStream = new FileStream("test.binary", FileMode.Create); IFormatter bf = new BinaryFormatter(); bf.Serialize(fileStream, myClass); fileStream.Dispose(); fileStream.Close(); fileStream = new FileStream("test.binary", FileMode.Open); bf = new BinaryFormatter(); myClass = (MyClass1)bf.Deserialize(fileStream); } }

I know that encoding is important, I've already tried ASCII, UTF-8, UTF-7 and this: BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); bf.Serialize(ms, clean); ms.Seek(0, 0); byte[] blob = ms.ToArray(); I dont know what else to do. I'll appreciate if somebody can help me. Thanks

  • How did My Object Get into ASP.NET Page State?

    - by Paul Knopf
    I know what this error is, how to fix it, etc. My question is that I don't know why my current page I am developing is throwing this error when I am not using the foo class directly in any way, nor am I setting anything to the viewstate. I am using postbacks alot, but like I said, I am not storing anything in the viewstate etc one integer. I am using nhibernate if that is relevant. Any idea why I need to mark this classes as serializable that arent being used? Where should I start investigating?

  • Is deserializing complex objects instead of creating them a good idea, in test setup?

    - by Chris Bye
    I'm writing tests for a component that takes very complex objects as input. These tests are mixes of tests against already existing components, and test-first tests for new features. Instead of re-creating my input objects (this would be a large chunk of code) or reading one from our data store, I had the thought to serialize a live instance of one of these objects, and just deserialize it into test setup. I can't decide if this is a reasonable idea that will save effort in long run, or whether it's the worst idea that I've ever had, causing those that will maintain this code will hunt me down as soon as they read it. Is deserialization of inputs a valid means of test setup in some cases? To give a sense of scale of what I'm dealing with, the size of serialization output for one of these input objects is 93KB. Obtained by, in C#: new BinaryFormatter().Serialize((Stream)fileStream, myObject);

  • Different Azure blob streams when using .Net client vs. REST interface

    - by knightpfhor
    I have encountered an unusual difference in the way that the .Net client for Azure and the direct REST API bring back streams of binary data. If I use the CloundBlob.DownloadToStream() vs. getting the response stream from the HTTP response, I get streams with the same length, but different content. Specifically the REST response seems to 0 out a series of bytes. I've discovered this issue because I'm trying to use the byte range feature for blobs which is currently not supported in the .Net client (if I'm wrong on this point and someone can point at where I can do this it might make the rest of this question irrelevant). If I upload a binary representation of the first 2k unicode characters with this code: Public Sub WriteFoo() Dim Blob As CloudBlob Dim Stream1 As MemoryStream Dim Container As CloudBlobContainer Dim Builder As StringBuilder Dim NextCharacter As String Dim Formatter As BinaryFormatter Container = CloudStorageAccount.DevelopmentStorageAccount.CreateCloudBlobClient.GetContainerReference("testcontainer") Container.CreateIfNotExist() Blob = Container.GetBlobReference("Foo") Stream1 = New MemoryStream() Builder = New Text.StringBuilder() For Index As Integer = 1 To 2000 Select Case Index Case Is <= 9 NextCharacter = ChrW(9) Case Is <= 31 NextCharacter = Environment.NewLine Case 127 NextCharacter = Environment.NewLine Case Else NextCharacter = ChrW(Index) End Select Builder.Append(NextCharacter) Next Formatter = New BinaryFormatter() Formatter.Serialize(Stream1, Builder.ToString()) Stream1.Position = 0 Blob.UploadFromStream(Stream1) End Sub Then try to access it with the following code: Public Sub ReadFoo() Dim Blob As CloudBlob Dim Request As System.Net.HttpWebRequest Dim Response As System.Net.WebResponse Dim ResponseSize As Integer Dim ResponseBuffer As Byte() Dim ResponseStream As Stream Dim Stream1 As MemoryStream Dim Stream2 As MemoryStream Dim Container As CloudBlobContainer Dim Byte1 As Integer Dim Byte2 As Integer Container = CloudStorageAccount.DevelopmentStorageAccount.CreateCloudBlobClient.GetContainerReference("testcontainer") Container.CreateIfNotExist() Blob = Container.GetBlobReference("Foo") Stream1 = New MemoryStream() Stream2 = New MemoryStream() Blob.DownloadToStream(Stream1) Request = DirectCast(System.Net.WebRequest.Create(Blob.Uri), System.Net.HttpWebRequest) Request.Headers.Add("x-ms-version", "2009-09-19") Request.Headers.Add("x-ms-range", String.Format("bytes={0}-{1}", 0, Integer.MaxValue)) Blob.Container.ServiceClient.Credentials.SignRequest(Request) Response = Request.GetResponse() ResponseStream = Response.GetResponseStream() ResponseSize = CInt(Response.ContentLength) ReDim ResponseBuffer(ResponseSize - 1) ResponseStream.Read(ResponseBuffer, 0, ResponseSize) Stream2.Write(ResponseBuffer, 0, ResponseSize) Stream1.Position = 0 Stream2.Position = 0 If Stream1.Length <> Stream2.Length Then System.Diagnostics.Debug.WriteLine(String.Format("Streams a different length. 1: {0}. 2: {1}", Stream1.Length, Stream2.Length)) Else While Stream1.Position < Stream1.Length Byte1 = Stream1.ReadByte() Byte2 = Stream2.ReadByte() If Byte1 <> Byte2 Then System.Diagnostics.Debug.WriteLine(String.Format("Streams differ at position {0}, 1: {1}. 2: {2}", Stream1.Position - 1, Byte1, Byte2)) End If End While End If End Sub Past all certain point all of the data in Stream2 (the data I've retrieved from the REST api) ends up being 0. To make matters even more confusing, when I reverse the order that I put the characters in the string e.g. For Index As Integer = 2000 To 1 rather than For Index As Integer = 1To 2000 it all works OK. Any help is much appreciated. My computer is sick of me swearing at it.

What is the problem? I dont understand. Thank you for your helps.

    I am serializing a generic dictionary in VB.net and I am very surprised that it is about 1.3kb with a single item. Am I doing something wrong, or is there something else I should be doing? I have a large number of dictionaries and it is killing me to send them all across the wire. The code I use for serialization is Dim dictionary As New Dictionary(Of Integer, Integer) Dim stream As New MemoryStream Dim bformatter As New BinaryFormatter() dictionary.Add(1, 1) bformatter.Serialize(stream, dictionary) Dim len As Long = stream.Length

  • Reinject dependencies of a freshly deserialized object

    - by NathanE
    If a program has literally just deserialized an object (doesn't really matter how, but just say BinaryFormatter was used). What is a good design to use for re-injecting the dependencies of this object? Is there a common pattern for this? I suppose I would need to wrap the Deserialize() method up to act as a factory inside the container. Thanks!

  • Add new property to a class at runtime using reflection...

    - by Lee
    I have some serialized data (using BinaryFormatter), and wanting to deserialise it. However the deserialise method failed since the current assembly does not have the deleted field. I want to be able to reconstruct earlier assembly at run-time in order to deserialise the data. Appreciated any pointer. Thanks.

  • mod_mono 'Service Temporarily Unavailable' issue

    - by Charlie Somerville
    I've deployed an ASP.NET web application on a Linux (Debian) server running Apache 2.2 and mod_mono 1.9 It's working well, however Mono occasionally segfaults and uses the entire CPU which causes the website to stop working and display 'Service Temporarily Unavailable' Killing mono fixes it, but obviously this isn't a good solution. I tailed the system log after this happened and I saw the following error messages from the kernel: Apr 20 01:49:37 charliesomerville kernel: [1596436.204158] mono[17909]: segfault at b645f671 ip b645f671 sp b4ffb604 error 4<6>mono[19047]: segfault at b645f66e ip b645f66e sp b4bf7604 error 4<6>mono[18017]: segfault at b645f66e ip b645f66e sp b52fe604 error 4<6>mono[19668]: segfault at b645f5e6 ip b645f5e6 sp b48f4604 error 4<6>mono[22565]: segfault at b645f674 ip b645f674 sp b45f1604 error 4<6>mono[17700]: segfault at b645f661 ip b645f661 sp b51fd604 error 4<6>mono[19596]: segfault at b645f5e6 ip b645f5e6 sp b49f5604 error 4 Apr 20 01:49:37 charliesomerville kernel: [1596436.208172] mono[23219]: segfault at b645f66e ip b645f66e sp b44f0604 error 4 At the end of Apache's error.log are the following errors: [Tue Apr 20 03:10:23 2010] [error] (70014)End of file found: read_data failed [Tue Apr 20 03:10:23 2010] [error] Command stream corrupted, last command was 1 [Tue Apr 20 03:10:23 2010] [error] Command stream corrupted, last command was 1 [Tue Apr 20 03:10:23 2010] [error] Command stream corrupted, last command was 1 System.ArgumentNullException: null key Parameter name: key at System.Collections.Hashtable.get_Item (System.Object key) [0x00000] at System.Runtime.Serialization.SerializationCallbacks.GetSerializationCallbacks (System.Type t) [0x00000] at System.Runtime.Serialization.ObjectManager.RaiseOnDeserializingEvent (System.Object obj) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadObjectContent (System.IO.BinaryReader reader, System.Runtime.Serialization.Formatters.Binary.TypeMetadata metadata, Int64 objectId, System.Object& objectInstance, System.Runtime.Serialization.SerializationInfo& info) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadObjectInstance (System.IO.BinaryReader reader, Boolean isRuntimeObject, Boolean hasTypeInfo, System.Int64& objectId, System.Object& value, System.Runtime.Serialization.SerializationInfo& info) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadObject (BinaryElement element, System.IO.BinaryReader reader, System.Int64& objectId, System.Object& value, System.Runtime.Serialization.SerializationInfo& info) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadNextObject (System.IO.BinaryReader reader) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadObjectGraph (System.IO.BinaryReader reader, Boolean readHeaders, System.Object& result, System.Runtime.Remoting.Messaging.Header[]& headers) [0x00000] at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.NoCheckDeserialize (System.IO.Stream serializationStream, System.Runtime.Remoting.Messaging.HeaderHandler handler) [0x00000] at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize (System.IO.Stream serializationStream) [0x00000] at System.Runtime.Remoting.Channels.CADSerializer.DeserializeObject (System.IO.MemoryStream mem) [0x00000] at System.Runtime.Remoting.RemotingServices.GetDomainProxy (System.AppDomain domain) [0x00000] at System.AppDomain.CreateDomain (System.String friendlyName, System.Security.Policy.Evidence securityInfo, System.AppDomainSetup info) [0x00000] at System.Web.Hosting.ApplicationHost.CreateApplicationHost (System.Type hostType, System.String virtualDir, System.String physicalDir) [0x00000] at Mono.WebServer.VPathToHost.CreateHost (Mono.WebServer.ApplicationServer server, Mono.WebServer.WebSource webSource) [0x00000] at Mono.WebServer.ApplicationServer.GetApplicationForPath (System.String vhost, Int32 port, System.String path, Boolean defaultToRoot) [0x00000] at (wrapper remoting-invoke-with-check) Mono.WebServer.ApplicationServer:GetApplicationForPath (string,int,string,bool) at Mono.WebServer.ModMonoWorker.GetOrCreateApplication (System.String vhost, Int32 port, System.String filepath, System.String virt) [0x00000] at Mono.WebServer.ModMonoWorker.InnerRun (System.Object state) [0x00000] at Mono.WebServer.ModMonoWorker.Run (System.Object state) [0x00000] [Tue Apr 20 03:10:26 2010] [error] (70014)End of file found: read_data failed [Tue Apr 20 03:10:26 2010] [error] Command stream corrupted, last command was -1 Along with the above errors, Apache's error.log is packed with hundreds (if not thousands) of the following error: Maximum number (20) of concurrent mod_mono requests to /tmp/mod_mono_dashboard_default_2.lock reached.

  • Microsoft SyncFramework - Sync different tables into one

    - by evnu
    Hello, we are trying to get the Microsoft SyncFramework running in our application to synchronize an oracle db with a mobile device. Problem The queries that we need to gather the data on the oracle db take much time (and we haven't found a way to speed them up yet), so we try to split them up in as much portions as possible. One big part of the whole problem is, that we need different information out of one big table, that bloats a query if combined. Unfortunately, the SyncFramework allows only one TableAdapter per SyncTable. Now this is a problem for our application: If we were able to use more than one TableAdapter per SyncTable, we could easily spread the queries in a more efficient way. Using one query per Table which combines all the needed data takes way too much time. Ideas I thought of creating different TableAdapters for each one of the required queries and then merge the resulting datasets afterwards (preferably on the server). This seems to work, but is a rather awkward solution. Does someone of you know a better solution? Or do you have some ideas that could help? Thanks in advance, evnu EDIT: So, I implemented the merge solution. If you are interested, take a look at the following code. I'll give more details if there are questions. <WebMethod()> _ Public Function GetChanges(ByVal groupMetadata As SyncGroupMetadata, ByVal syncSession As SyncSession) As SyncContext Dim stream As MemoryStream Dim format As BinaryFormatter = New BinaryFormatter Dim anchors As Dictionary(Of String, Byte()) ' keep track of the tables that will be updated Dim addTables As Dictionary(Of String, List(Of SyncTableMetadata)) = New Dictionary(Of String, List(Of SyncTableMetadata)) ' list of all present anchors Dim allAnchors As Dictionary(Of String, Byte()) = New Dictionary(Of String, Byte()) ' fill allAnchors - deserialize all given anchors For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata If Table.LastReceivedAnchor Is Nothing Or Table.LastReceivedAnchor.IsNull Then Continue For stream = New MemoryStream(Table.LastReceivedAnchor.Anchor) anchors = format.Deserialize(stream) For Each item As KeyValuePair(Of String, Byte()) In anchors allAnchors.Add(item.Key, item.Value) Next stream.Dispose() Next For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata If allAnchors.ContainsKey(Table.TableName) Then Table.LastReceivedAnchor.Anchor = allAnchors(Table.TableName) End If Dim addSyncTables As List(Of SyncTableMetadata) If syncSession.SyncParameters.Contains(Table.TableName) Then Dim tableNames() As String = syncSession.SyncParameters(Table.TableName).Value.ToString.Split(":") addSyncTables = New List(Of SyncTableMetadata) For Each tableName As String In tableNames Dim newSynctable As SyncTableMetadata = New SyncTableMetadata newSynctable.TableName = tableName If allAnchors.ContainsKey(tableName) Then Dim anker As SyncAnchor = New SyncAnchor(allAnchors(tableName)) newSynctable.LastReceivedAnchor = anker Else newSynctable.LastReceivedAnchor = Nothing End If newSynctable.SyncDirection = Table.SyncDirection addSyncTables.Add(newSynctable) Next addTables.Add(Table.TableName, addSyncTables) End If Next ' add the newly created synctables For Each item As KeyValuePair(Of String, List(Of SyncTableMetadata)) In addTables For Each Table As SyncTableMetadata In item.Value groupMetadata.TablesMetadata.Add(Table) Next Next ' fire queries Dim context As SyncContext = servSyncProvider.GetChanges(groupMetadata, syncSession) ' merge resulting datasets For Each item As KeyValuePair(Of String, List(Of SyncTableMetadata)) In addTables For Each Table As SyncTableMetadata In item.Value If context.DataSet.Tables.Contains(Table.TableName) Then If Not context.DataSet.Tables.Contains(item.Key) Then Dim tmp As DataTable = context.DataSet.Tables(Table.TableName).Copy tmp.TableName = item.Key context.DataSet.Tables.Add(tmp) Else context.DataSet.Tables(item.Key).Merge(context.DataSet.Tables(Table.TableName)) context.DataSet.Tables.Remove(Table.TableName) End If End If Next Next ' create new anchors Dim allAnchorsDict As Dictionary(Of String, Byte()) = New Dictionary(Of String, Byte()) For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata allAnchorsDict.Add(Table.TableName, context.NewAnchor.Anchor) Next stream = New MemoryStream format.Serialize(stream, allAnchorsDict) context.NewAnchor.Anchor = stream.ToArray stream.Dispose() Return context End Function

  • Deserializing Metafile

    - by Kildareflare
    I have an application that works with Enhanced Metafiles. I am able to create them, save them to disk as .emf and load them again no problem. I do this by using the gdi32.dll methods and the DLLImport attribute. However, to enable Version Tolerant Serialization I want to save the metafile in an object along with other data. This essentially means that I need to serialize the metafile data as a byte array and then deserialize it again in order to reconstruct the metafile. The problem I have is that the deserialized data would appear to be corrupted in some way, since the method that I use to reconstruct the Metafile raises a "Parameter not valid exception". At the very least the pixel format and resolutions have changed. Code use is below. [DllImport("gdi32.dll")] public static extern uint GetEnhMetaFileBits(IntPtr hemf, uint cbBuffer, byte[] lpbBuffer); [DllImport("gdi32.dll")] public static extern IntPtr SetEnhMetaFileBits(uint cbBuffer, byte[] lpBuffer); [DllImport("gdi32.dll")] public static extern bool DeleteEnhMetaFile(IntPtr hemf); The application creates a metafile image and passes it to the method below. private byte[] ConvertMetaFileToByteArray(Image image) { byte[] dataArray = null; Metafile mf = (Metafile)image; IntPtr enhMetafileHandle = mf.GetHenhmetafile(); uint bufferSize = GetEnhMetaFileBits(enhMetafileHandle, 0, null); if (enhMetafileHandle != IntPtr.Zero) { dataArray = new byte[bufferSize]; GetEnhMetaFileBits(enhMetafileHandle, bufferSize, dataArray); } DeleteEnhMetaFile(enhMetafileHandle); return dataArray; } At this point the dataArray is inserted into an object and serialized using a BinaryFormatter. The saved file is then deserialized again using a BinaryFormatter and the dataArray retrieved from the object. The dataArray is then used to reconstruct the original Metafile using the following method. public static Image ConvertByteArrayToMetafile(byte[] data) { Metafile mf = null; try { IntPtr hemf = SetEnhMetaFileBits((uint)data.Length, data); mf = new Metafile(hemf, true); } catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message); } return (Image)mf; } The reconstructed metafile is then saved saved to disk as a .emf (Model) at which point it can be accessed by the Presenter for display. private static void SaveFile(Image image, String filepath) { try { byte[] buffer = ConvertMetafileToByteArray(image); File.WriteAllBytes(filepath, buffer); //will overwrite file if it exists } catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message); } } The problem is that the save to disk fails. If this same method is used to save the original Metafile before it is serialized everything is OK. So something is happening to the data during serialization/deserializtion. Indeed if I check the Metafile properties in the debugger I can see that the ImageFlags, PropertyID, resolution and pixelformats change. Original Format32bppRgb changes to Format32bppArgb Original Resolution 81 changes to 96 I've trawled though google and SO and this has helped me get this far but Im now stuck. Does any one have enough experience with Metafiles / serialization to help..? EDIT: If I serialize/deserialize the byte array directly (without embedding in another object) I get the same problem.

  • WCF Stream.Read always returns 0 in client

    - by G_M
    I've spent most of my day trying to figure out why this isn't working. I have a WCF service that streams an object to the client. The client is then supposed to write the file to its disk. But when I call stream.Read(buffer, 0, bufferLength) it always returns 0. Here's my code: namespace StreamServiceNS { [ServiceContract] public interface IStreamService { [OperationContract] Stream downloadStreamFile(); } } class StreamService : IStreamService { public Stream downloadStreamFile() { ISSSteamFile sFile = getStreamFile(); BinaryFormatter bf = new BinaryFormatter(); MemoryStream stream = new MemoryStream(); bf.Serialize(stream, sFile); return stream; } } Service config file: <system.serviceModel> <services> <service name="StreamServiceNS.StreamService"> <endpoint address="stream" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IStreamService" name="BasicHttpEndpoint_IStreamService" contract="SWUpdaterService.ISWUService" /> </service> </services> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_IStreamService" transferMode="StreamedResponse" maxReceivedMessageSize="209715200"></binding> </basicHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior> <serviceThrottling maxConcurrentCalls ="100" maxConcurrentSessions="400"/> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> </system.serviceModel> Client: TestApp.StreamServiceRef.StreamServiceClient client = new StreamServiceRef.StreamServiceClient(); try { Stream stream = client.downloadStreamFile(); int bufferLength = 8 * 1024; byte[] buffer = new byte[bufferLength]; FileStream fs = new FileStream(@"C:\test\testFile.exe", FileMode.Create, FileAccess.Write); int bytesRead; while ((bytesRead = stream.Read(buffer, 0, bufferLength)) > 0) { fs.Write(buffer, 0, bytesRead); } stream.Close(); fs.Close(); } catch (Exception e) { Console.WriteLine("Error: " + e.Message); } Client app.config: <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpEndpoint_IStreamService" maxReceivedMessageSize="209715200" transferMode="StreamedResponse"> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://[server]/StreamServices/streamservice.svc/stream" binding="basicHttpBinding" bindingConfiguration="BasicHttpEndpoint_IStreamService" contract="StreamServiceRef.IStreamService" name="BasicHttpEndpoint_IStreamService" /> </client> </system.serviceModel> (some code clipped for brevity) I've read everything I can find on making WCF streaming services, and my code looks no different than theirs. I can replace the streaming with buffering and send an object that way fine, but when I try to stream, the client always sees the stream as "empty". The testFile.exe gets created, but its size is 0KB. What am I missing?

  • nginx bad gateway 502 with mono fastcgi

    - by Bradley Lederholz Leatherwood
    Hello so I have been trying to get my website to run on mono (on ubuntu server) and I have followed these tutorials almost to the letter: However when my directory is not blank fastcgi logs reveal this: Notice Beginning to receive records on connection. Error Failed to process connection. Reason: Exception has been thrown by the target of an invocation. I am not really sure what this means, and depending on what I do I can get another error that tells me the resource cannot be found: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /Default.aspx/ Version information: Mono Runtime Version: 2.10.8 (tarball Thu Aug 16 23:46:03 UTC 2012) ASP.NET Version: 4.0.30319.1 If I should provide some more information please let me know. Edit: I am now getting a nginx gateway error. My nginx configuration file looks like this: server { listen 2194; server_name localhost; access_log $HOME/WWW/nginx.log; location / { root $HOME/WWW/dev/; index index.html index.html default.aspx Default.aspx Index.cshtml; fastcgi_index Views/Home/; fastcgi_pass 127.0.0.1:8000; include /etc/nginx/fastcgi_params; } } Running the entire thing with xsp4 I have discovered what the "Exception has been thrown by the target of an invocation."
