    - Locate ending bracket in VS for obfuscated code ! Hi, I am using Visual Studio 2005 to debug a program. It is like obfuscated code, so I wonder if given a starting bracket, VS can tell me where the closing bracket is. By the way, I also wonder if this is the right group to ask these questions. Otherwise suggestions are welcome ! Thanks in advance Tag: Best Book for WorkFlow Tag: 138029

    - distribuzione di un'applicazione Ho finito di sviluppare un'applicazione Windows (C# 2005), composta di un .exe di avvio e vari .dll, e la devo distribuire. Domanda: come faccio a impedire che le dll che distribuisco insieme allâ??applicazione siano open source, cioÃ¨ utilizzabili per un altro progetto (non mio) semplicemente aggiungendole come riferimento a questo progetto?

    - LINQ question This is a multi-part message in MIME format. ------=_NextPart_000_00EE_01C884E8.00DD6E90 Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original Content-Transfer-Encoding: 7bit I have a desktop aplication which use an embeded database engine (embeded in the application that is) to store its data. And I used LINQ 2 SQL as an ORMapper to synchronize the database with my object representation in memory. What I want to do is load most object at the start, do in memory work, and occasionaly load additional big data or save the changes. I have a problem with the DataContext.GetTable<T>() mehod. It seems everytime I do a foreach on its retur it will query the database, is that true? So in my particular case I'm better off working with an List<T> which I will initialize from the GetTable<T> result? Just in case I wrote such a list (Code attached) and I wonder if I did it the proper way, if anyone can take a look? Also I have a table like that Data -------- ID int summary nvarchar(256) content image which I loaded in [Table("Data")] class Data { [Column(...)] public int ID {get; set; } [Column(...)] public sring Sumary { get; set; } [Column(...)] public byte[] Content { get; set; } } Now Content is potentially big and I want to use lazy loading, i.e. I DON'T want to load the 'byte[] Content' with the rest of the data (I guess it's easy, just remove the ColumnAttribute), but I DO want to save the Content, if it's not null (i.e. if it has been explicitely loaded/set/modified) when SubmitChanges() is called on the Context. Any tip on how to do that? Moreover, if I only change the content (which will have no ColumnAttribute) how do I mark my entity as dirty in the context? (i.e. I would need an 'UpdateOnSubmit()' method in the table, but it doesn't exists..) ------=_NextPart_000_00EE_01C884E8.00DD6E90 Content-Type: text/plain; format=flowed; name="LinqList.cs"; reply-type=original Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="LinqList.cs" =EF=BB=BFusing System; using System.Collections.Generic; using System.Data.Linq; using System.Linq; using System.Linq.Expressions; using System.Text; namespace Galador.Utils.SQL { /// <summary> /// This will hol an in memory representation of some LINQ data. /// All data will be loaded at creation time and furter work would /// be done in memory. /// </summary> /// <typeparam name=3D"T"></typeparam> public class LinqList<T> : IList<T> where T : class { List<T> data; public LinqList(DataContext ctxt) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>()); } public LinqList(DataContext ctxt, Expression<Func<T, bool>> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Expression<Func<T, int, bool>> = predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Func<T, bool> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public LinqList(DataContext ctxt, Func<T, int, bool> predicate) { if (ctxt =3D=3D null) throw new ArgumentNullException("ctxt"); data =3D new List<T>(ctxt.GetTable<T>().Where<T>(predicate)); } public DataContext Context { get; private set; } #region IList<T> Members public int IndexOf(T item) { return data.IndexOf(item); } public void Insert(int index, T item) { if (item !=3D null) Context.GetTable<T>().InsertOnSubmit(item); data.Insert(index, item); } public void RemoveAt(int index) { T item =3D data[index]; if (item !=3D null) Context.GetTable<T>().DeleteOnSubmit(item); data.RemoveAt(index); ; } public T this[int index] { get { return data[index]; } set { RemoveAt(index); Insert(index, value); } } #endregion #region ICollection<T> Members public void Add(T item) { Insert(Count, item); } public void Clear() { Context.GetTable<T>().DeleteAllOnSubmit<T>(data); data.Clear(); } public bool Contains(T item) { return data.Contains(item); } public void CopyTo(T[] array, int arrayIndex) { data.CopyTo(array, arrayIndex); } public int Count { get { return data.Count; } } public bool IsReadOnly { get { return false; } } public bool Remove(T item) { int index =3D IndexOf(item); if (index < 0) return false; RemoveAt(index); return true; } #endregion #region IEnumerable<T> Members public IEnumerator<T> GetEnumerator() { return data.GetEnumerator(); } #endregion #region IEnumerable Members System.Collections.IEnumerator = System.Collections.IEnumerable.GetEnumerator() { return GetEnumerator(); = } #endregion } } ------=_NextPart_000_00EE_01C884E8.00DD6E90-- Tag: Best Book for WorkFlow Tag: 138024

    - How to capture "printfs" from unmanaged C++ I posted this to the interop group. I'm reposting to troll for a few more ideas. In my managed C# app we capture trace statements and direct them to a log file using trace listeners. Part of the app uses unmanaged C++ dlls, and unfortunately, the C++ printfs don't get picked up and are simply printed to the console window. Is there any way I can capture the output of the printfs and then redirect them to the same file that the trace listener is writing to? I do have access to the unmanaged C++ code if the solution involves not using printfs. The important thing is that the C++ printfs and the C# trace messages end up in the same file. One solution from the interop group was to compile the C++ with /clr and then replace the printfs with Trace.WriteLine(). Any less invasive techniques. Maybe somehow redirecting the printfs to someplace that can be picked up by .Net. Thanks Mitch Tag: Best Book for WorkFlow Tag: 138023

    - System.Timers.Timer and Close/Dispose The short form of this post is as follows. For an instance of System.Timers.Timer, after setting Enabled to False, is there a foolproof way to tell if an Elapsed event will or will not fire? The long form follows. I have a class, MyClass, that declares Private WithEvents MyTimer As System.Timers.Timer Sub New for MyClass initializes MyTimer to fire Elapsed events every second. I have an Elapsed event handler and some public methods. With SyncLock, I've made MyClass instances thread safe. Everything works fine. System.Timers.Timer has Close and Dispose methods, so I when I want to destroy an instance of MyClass, I should Close or Dispose MyTimer. I've coded MyClass.Close to look like this: MyTimer.Enabled = False ' some cleanup I need to do Sleep(100) ' let fire an enroute MyTimer.Elapsed MyTimer.Dispose() ' per IDisposable ' some more cleanup I need to do The reason for the Sleep is because of how Windows/.NET executes MyTimer.Elapsed events. The Timer.Stop documentation says: "The Elapsed event is raised on a ThreadPool thread, so the event-handling method might run on one thread at the same time that a call to the Stop method runs on another thread. This might result in the Elapsed event being raised after the Stop method is called." Stop and Enabled=False do the same thing. The Timer.Stop documentation goes on to give a somewhat elaborate mechanism to overcome contention and race conditions that might arise. My solution is Sleep(100). I don't like my use of Sleep. I don't like the elaborate mechanism in the documentation because it looks like it could fail if someone is messing with thread priorities (note that the mechanism uses Sleep(0)). So, the question is: For an instance of System.Timers.Timer, after setting Enabled to False, is there a foolproof way to tell if an Elapsed event will or will not fire?

    - Good C# profilers? Hi... I was just wondering what recommendations people had for C# code profilers? I'm trying to figure out where a lot of our app's time is going. I downloaded and am trying ProfileSharp Enterprise Edition, but I'm finding the interface awkward and the results suspect (profiling for cpu cycles, it says Thread.Sleep is the most expensive function). Has anyone had particularly good experience with a C# code profiler? Thanks Mark Tag: Best Book for WorkFlow Tag: 138003

    - EnterpriseLibrary.Logging Hi all, I have installed EnterpriseLibrary v3.1 (latest version) on my pc. When I create the app.config file using the "EnterpriseLibrary Configuration" utility, I get an error saying it can't detect the EL.Logging.dll file. I fixed the problem by setting the PublicKeyToken= "null" instead of its default PublicKeyToken="b03f5f7f11d50a3a". eg. configSections> <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" /> <section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" /> </configSections> The thing is that I can't understnad why this error is occuring in the first place. This pc is newly set-up and it has never had any prior versions of EL installed on it. The "EnterpriseLibrary Configuration" utility comes with this v3.1 setup. Thanks for your reply. regards, Andrew Tag: Best Book for WorkFlow Tag: 137998

    - GDI and Rotating Text Hi, I want to use GDI to rotate some text at an angle and output the resultant image to the asp.net response stream. I can do that all fine, however what I'm struggling with is trimming the whitespace from the resultant image. What im doing is creating a blank canvas image (of arbitrarily large size) and doing a translate transform to the centre, then applying a rotate transform, then writing my text. What i want to do is trim all the whitespace from around the edges. Is there some way i can determine the width and height of the text ive written to the image (after the transform) ? I know i can manually get the text dimensions before the rotate, then use some trig to work out how high and wide it would be after rotating it but thats a bit of a pain if theres some function that will do it for me Thanks for any advice Andrew Tag: Best Book for WorkFlow Tag: 137996

    - Windows service startUp error Hi all, My question consists of 2 parts: 1) I have installed my windows service [by right-click on Setup.exe in SolutionExplorer, then Install ... ] onto a folder on my desktop. When I click on the MyNewService.exe file, I got the following error message: " Cannot start service from the command line or a debugger. A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command. " 2) Is the problem because I need to install using "installutil /i C:\MyNewService3.exe" ? I tried that and i got the error message: " Exception occurred while initializing the installation: System.IO.FileNotFoundException: File or assembly name Documents, or one of its dependencies, was not found.

    - Caching of DateTime.Now? Hi... We have some elapsed time stopwatches using the QueryPerformanceCounter() win32 api, but since I was getting tired of doing the arithmatic all the time I added some DateTime.Now.ToString("HH:mm:ss.fff")'s to the log and I noticed an interesting quirk. There's often about a 5ms difference between the calculations of QueryPerformanceCounter() values and DateTime.Now and DateTime.Now is always the one behind. Is DateTime.Now cached for some period of time to avoid the expense of recalculation? Thanks Mark Tag: Best Book for WorkFlow Tag: 137977

    - File Copy exception Hi all, I have created a windows service (my first service). I am normally an ASP.NET developer... The service is simple. All it does is to watch a directory and copy any files that land in it to another folder (in this case, the parent folder). This works fine most of the time, but my first sample file crashed it. It seems to be down to a file type problem. My sample file was a .bat file. I have now put a try/catch around the file copy and come up with _COMPlusExceptionCode -532459699 At the moment, it only seems to crash with .bat files. I have done a successful copy of app.config, *.txt. Any ideas? My code... public MyService() { InitializeComponent(); } protected override void OnStart(string[] args) { // TODO: Add code here to start your service. FSWatcher.Path = ConfigurationManager.AppSettings["WatchPath"]; } protected override void OnStop() { // TODO: Add code here to perform any tear-down necessary to stop your service. } private void FSWatcher_Created(object sender, System.IO.FileSystemEventArgs e) { try { System.IO.File.Copy(e.FullPath, "C:\\temp\\" + e.Name); } catch (Exception ex) { } } -- Best regards, Dave Colliver. http://www.AshfieldFOCUS.com ~~ http://www.FOCUSPortals.com - Local franchises available Tag: Best Book for WorkFlow Tag: 137975

    - Metafile & Graphics I have a Metafile and a Graphics attached to it and I do several drawings on the Metafile through the Graphics. After the drawings I need to print the metafile. If I try to print the Metafile right away, nothing shows on the page, now, If I do a Graphics.Dispose() and then print the Metafile, it works without any problem. My problem is that after printing the Metafile I still need to work on it through the Graphics, but if I try to reinitializate the Graphics object with a call of Graphics.FromImage(metafile), I get a "out of memory" error. Is there a different way to create a Graphics from a Metafile ? Is it possible to have access to a Metafile which is attached to a Graphics, without having to dispose the Graphics ?

    - Compiling WF assemblies with /platform:x64 Hello, I have a service application that uses Windows Workflow Foundation as part of its processes. One of the class libraries in this application is a collection of custom WF activities that I have written to represent the bits of business process. The solution compiles fine when compiling with the /platform:anycpu flag and all is good, but when I try to compile the same solution with the /platform:x64 the class library with the WF activities fail with a "error 348: Compilation failed." It goes on to say "Unable to load one or more of the requested types." but that's all the help I get. I'm trying to build the application in a 32 bits machine running Windows XP SP2, but I will run it in a Windows Server 2003 64 bits. On the destination machine I have installed the 64 bit version of the Framework 3.5 and when looking in "C:\WINDOWS\Microsoft.NET\Framework64\v3.0" I can see only two sub-folders: "Windows Communication Foundation" and "WPF", whereas in the 32 bit version of the Framework 3.0 I can see a third folder called "Windows Workflow Foundation". Does it have any relevance? Any help is appreciated. Tag: Best Book for WorkFlow Tag: 137972

    - Need help diagnosing WCF timeout exception Hello, I have a Windows Service-hosted WCF service that occasionally throws an timeout exception, or something that looks like one. The call chain looks like this: Client->WCF Service->COM Server->COM App The exception seems to appear as the call to the service is completing. Interestingly, these exceptions do not seem to affect the tasks the service is performing at the time of the error. If the errors are ignored all subsequent dependent actions are successful. The exception message is: The maximum retry count has been exceeded with no response from the remote endpoint. The reliable session was faulted. This is often an indication that the remote endpoint is no longer available. The inner exception says: The HTTP request to 'http://xpsp2client:8000/CubularityServies/CuIWfcService' has exceeded the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout. I also occasionally see an exception claiming that I've exceeded the inactivityTimeout of 00:10:00. OK. When I started seeing these I set all the timeout values I could find to 00:20:00 and the behavior was not affected. I'm setting the following timeouts in the .config file: For <binding> : receiveTimeout sendTimeout openTimeout closeTimeout For <reliableSession> : inactivityTimeout For <host> : openTimeout closeTimeout I'm wondering if there are timeout settings that I'm missing. I don't have any values less than 20min yet I get errors telling me I've exceeded timeouts of 1 and 10 minutes. I've used Intellisense to poke around and try to find properties that aren't obvious in the WCF Config Editor, but haven't turned up anything. Any suggestions? Keith P.S. I've turned on verbose logging for the service and am trying to understand them. Some exceptions are shown in the logs but not enough detail is given to pinpoint the source of these faliure.

One project contains datasets with table adapters. When I opened a usercontrol in design mode, it used to have all datasets and tableadapters in toolbox, under a tab name with the name of the datasets project However, I had to upgrate to a new hdd, and did a clean Windows install, with VS2005, etc Now, when I open te solution and open a usercontrol in designer, I see only the other user controls, but no datasets or table adapters as I used to have before. Sometimes I see a tab with the name of the datasets project, but on it there is a text telling "There are no usable controls in this group" What happend? I mention, on old HDD I had instaled VS2003 and VS2005, on new one I have only VS2005 and installed VS2008 express, but then I removed it (as I thought maybe it caused the issue).

    - Updating a collection using a lambda Hi - I have a situation where I'd like to use a lambda, but I'm not sure how. Basically, I have a collection of objects and I want to set a property on each object that meets a condition. Right now, I have this: IEnumerable<VariableCode> codes = variable.VariableCodeList.Where(c => c.Type == "MyCondition"); foreach (VariableCode code in codes) { code.IsShown = true; }//foreach I'm thinking that I can replace the foreach bit with a single lambda expression. Can anyone help me with that syntax? Thanks. -- -Paul Prewett Tag: Best Book for WorkFlow Tag: 137920

    - web deployed assembly I have a windows forms assembly that needs to be deployed via a webpage. This bit of code must provide a fully automated printing solution; in that it must accept a parameter containing a graphic image to print, and print it without any interaction. The issue I'm having is that it throws a security exception [Request for permission of type: System.drawing.printing.printingpermission ... failed]. This bit of code seems to work just fine if I use the print dialogbox and select the appropriate printer, and of course fails if I don't use the dialogbox. This seems to be a security issue, but I'm not sure where to look, or how to fix it. And, so as to head off a couple of other issues; I need to pass a parameter to it from the HTML page, and it has to be served by Linux. Thanks. Tag: Best Book for WorkFlow Tag: 137919

    - AccessViolationException with AutoCompleteStringCollection Update Hi, i have form with a text box that uses a AutoCompleteStringCollection for auto completion. Now if a new value (one not yet contained in the collection) is entered, the new value should be added to the collection. Sounds simple, but i often (not always) get a System.NullReferenceException: with as Stack trace as follows: bei System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW bei System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop bei System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner bei System.Windows.Forms.Application.ThreadContext.RunMessageLoop bei System.Windows.Forms.Application.Run bei FwO.Entry.MainClass.Main and with that my application crashes. Does anyone have any idea of what might cause this error and how i can prevent it? Thanks for any info./suggestion! Regards, Frank Tag: Best Book for WorkFlow Tag: 137918

    - is there difference between XP Pro and Server2003? Hi, my local machine is XP Pro. when I built the WCF hosted in IIS, it works fine. (create virtual directory on IIS and open that website and coding.. that's it.) but When I try to built the WCF hosted in IIS in server machine, it causes error. (create virtual directory on IIS and open that website and coding. same with xp pro) my server machine is Server2003. After I publish this on the different location in server2003 IIS, it works fine. Do I have to publish the WCFservice? Is there difference between XP Pro and Server2003? When I publish this, I have to be very careful since they just clean that folder automatically.

    - Does HttpListener have the same quirk as HttpWebRequest Hi... We've implemented a server process using HttpListener to get and process certain requests, but we've been noticing some odd serialization that reminded me of a quirk in the client code. We recently discovered an odd behavior of HttpWebRequest in the client code where mixing sync and async methods resulted in everything quietly being sync. Specifically, we were using GetRequestStream() to send the data up synchronously then calling BeginGetResponse() to wait for the answer async. Well, it turned out that if you call a sync method first the async calls magically turn into synchronized ones - a rather undocumented behavior. Now we're seeing some similar quirks on the server side with HttpListener. We use BeginGetContext() to listen for a request. Our callback calls EndGetContext() to get the details and then immediately calls BeginGetContext() again to wait for another request. But then we read the request synchronously, post the work in a queue with the associated response object and move on. What we're seeing is that if the client sends several requests in a row, it blasts right through them but the server doesn't acknowledge even reading the 2nd request until after the response to the first request is written to and closed. Does HttpListener have some implicit serialization behavior like HttpWebRequest? Thanks Mark Tag: Best Book for WorkFlow Tag: 137904

    - Any CPU assemblies, Framework64, and Process Explorer Hi... We're building our assemblies Any CPU and just now trying to throw them up on an x64 box. I was using Process Explorer to look at something else, and I noticed something peculiar. All of our assemblies were in the Framework64 temporary assembly cache for the running process but Process Explorer had flagged them all as being 32-bit code. Is this a quirk of Process Explorer not having a mind-meld of the .Net framework and understanding how the code is being executed, or is Process Explorer right and it's running in 32-bit mode, despite where it's running from?

    - New Information on Error 1603 when installing .NET Framework all I was having major issues with installing Visual Studio 2008 on my computer. In particular the .NET 3.5 component required to run Visual Studio 2008. I tried everything that was online from editing registry settings, setting access permissions and all. I was able to install up to .NET FW 2.0 but past that I kept getting error 1603. This error is usually an access error telling the user that the target drive, folder or file is unaccessible. I found when doing a verbose log with the install the Microsoft IIS installation on my computer was corrupted and I needed to reinstall IIS on my computer. The best fix for this issue is 1st: Uninstall the IIS server off of the computer. 2nd: Run the .NET FW 3.5 Installer 3rd: Re-Install IIS from the Windows CD-ROM. 4th: I was then able to install Visual Studio 2008 on my computer after fixing this. I hope this helps everyone out and sheds some light on installing. Tag: Best Book for WorkFlow Tag: 137902

    - Call for speakers for DataServices World (June 24, New York City) Call for Speakers Closes March 15 DataServices World New York City (June 24, 2008) The complexities of distributed processing and the importance of middleware can elude even senior technical people, including enterprise architects, IT managers, consultants and designers. Enterprise developers embraced the separation of presentation, data services and application logic. Internet computing, web services and service-oriented architecture (SOA) continued a trend towards moving data access and data integration logic into a separate data services layer. The data services layer, databases and data access are the focus of DataServices World. We're looking for technical presentations about architecture and solutions for data access and data integration from heterogeneous data sources including SQL tables, geo-coded data, content management systems, enterprise resource planning (ERP) systems, data warehouses, and web data. Topics of interest include: · End-to-end performance optimization: (database, metadata, data distribution, caching, query tuning, load balancing, protocols, data services) · Information as a service · Data services development: architecture, tools, LINQ, ADO.NET Entity Framework, Astoria · Essential capabilities for effective, robust, secure data services If you're interested in speaking, you must submit a proposal by March 15, 2008.

    - 403: Forbidden exception Hi there, I'm traying to consume a web service over an https:// connection (see some threads before ;-) ), and I got it: System.Net.WebException The request failed with HTTP status 403: Forbidden. at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) ... Is this because I need to authenticate with username and password? Or is because of som certificate-related issue? In the first case (authentication), should I use the following? Service proxy = new Service(); //new web service proxy instance; string username = ConfigurationManager.AppSettings["Username"]; //read username from the config file string password = ConfigurationManager.AppSettings["Password"]; //read password from the config file System.Net.NetworkCredential credentials = new System.Net.NetworkCredential(username, password); proxy.Credentials = credentials; Thanks in advance, Giulio - Italia -- OnAir: Emily Loizeau - "Sur la route" http://www.giuliopetrucci.it Tag: Best Book for WorkFlow Tag: 137893

    - Passing a Generic as a Parameter This seems like something that should be possible, but I am having trouble setting up a function to accept a generic type as a parameter.

    - 1.1 install and 3.0 uninstall My computer runs Windows XP. I have a perpetual automatic update message for an Express Install. It is trying to install .NET Framework 1.1 Service Pack 1. It fails, says simply it was unable to install, and then goes back into the windows update queue. I have read on other posts to try and uninstall from 3.0 downward and then reinstall from 1.1 forward. I am also unable to uninstall 3.0. It says that a newer version is on my computer and I need to remove from Add/Remove programs. The problem is I was trying to uninstall FROM Add/Remove programs. I have also tried the 3.0 uninstaller on the Microsoft website but it says "We did not find specified products to be installed." Excuse me - didn't the download say "Uninstall?" HELP!!! I'm so confused! Tag: Best Book for WorkFlow Tag: 137864

    - Socket connection was forcibly closed by the remote host Hy everyone, I have a little problem doing socket-programming. I've made a console-application with a socket listening on a sertain port to accept connections from other clients. The only thing my application has to do is accept the incomming clients, read the data and send it to a database. Everything works fine, but now and then my socket server seems to crash/hang. When I check my error-handling I see that my application is throwing this exception : "An existing connection was forcibly closed by the remote host" Restarting my application solves this problem. I don't know the reason, nor how to solve it. I've already surfed the internet al lot, but dit not come to an satisfying answer. Someone who can help me or who has experienced the same problem ?
