• F# DataContractJsonSerializer StackOverflowException

  - by akaphenom

  dataElementsList : TypesAndData.DataElement list is a list of 50,000 records (actually many more but lest start small). I am trying to serialize to JSON file: let ser = Json.DataContractJsonSerializer(typeof<TypesAndData.DataElement list>) use ofs = File.OpenWrite(fileName) let result = ser.WriteObject(ofs, dataElementsList) and am getting the infamous StackOverflowException. to be precise: An unhandled exception of type 'System.StackOverflowException' occurred in FSharp.Core.dll any advice?

• StackOverFlowException - but oviously NO recursion/endless loop

  - by user567706

  Hi there, I'm now blocked by this problem the entire day, read thousands of google results, but nothing seems to reflect my problem or even come near to it... i hope any of you has a push into the right direction for me. I wrote a client-server-application (so more like 2 applications) - the client collects data about his system, as well as a screenshot, serializes all this into a XML stream (the picture as a byte[]-array]) and sends this to the server in regular intervals. The server receives the stream (via tcp), deserializes the xml to an information-object and shows the information on a windows form. This process is running stable for about 20-25 minutes at a submission interval of 3 seconds. When observing the memory usage there's nothing significant to see, also kinda stable. But after these 20-25 mins the server throws a StackOverflowException at the point where it deserializes the tcp-stream, especially when setting the Image property from the byte[]-array. I thoroughly searched for recursive or endless loops, and regarding the fact that it occurs after thousands of sucessfull intervals, i could hardly imagine that. public byte[] ImageBase { get { MemoryStream ms = new MemoryStream(); _screen.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); return ms.GetBuffer(); } set { if (_screen != null) _screen.Dispose(); //preventing well-known image memory leak MemoryStream ms = new MemoryStream(value); try { _screen = Image.FromStream(ms); //<< EXCEPTION THROWING HERE } catch (StackOverflowException ex) //thx to new CLR management this wont work anymore -.- { Console.WriteLine(ex.Message + Environment.NewLine + ex.StackTrace); } ms.Dispose(); ms = null; } } I hope that more code would be unnecessary, or it could get very complex... Please help, i have no clue at all anymore thx Chris

• Linq to SQL generates StackOverflowException in tight Insert loop

  - by ChrisW

  I'm parsing an XML file and inserting the rows into a table (and related tables) using LinqToSQL. I parse the XML file using LinqToXml into IEnumerable. Then, I create a foreach loop, where I build my LinqToSQL objects and call InsertOnSubmit and SubmitChanges at the end of each loop. Nothing special here. Usually, I make it through around 4,100 records before receiving a StackOverflowException from LinqToSql, right as I call SubmitChanges. It's not always on 4,100... sometimes it's 4102, sometimes, less, etc. I've tried inserting the records that generate the failure individually, but putting them in their own Xml file, but that inserts fine... so it's not the data. I'm running the whole process from an MVC2 app that is uploading the Xml file to the server. I've adjusted my WebRequest timeouts to appropriate values, and again, I'm not getting timeout errors, just StackOverflowExceptions. So is there some pattern that I should follow for times when I have to do many insertions into the database? I never encounter this exception on smaller Xml files, just larger ones.

• List<element> initialization fires "Process is terminated due to StackOverflowException"

  - by netmajor

  I have structs like below and when I do that initialization: ArrayList nodesMatrix = null; List<vertex> vertexMatrix = null; List<bool> odwiedzone = null; List<element> priorityQueue = null; vertexMatrix = new List<vertex>(nodesNr + 1); nodesMatrix = new ArrayList(nodesNr + 1); odwiedzone = new List<bool>(nodesNr + 1); priorityQueue = new List<element>(); arr.NodesMatrix = nodesMatrix; arr.VertexMatrix = vertexMatrix; arr.Odwiedzone = odwiedzone; arr.PriorityQueue = priorityQueue; //only here i have exception debuger fires Process is terminated due to StackOverflowException :/ Some idea why this collection fires this exception ? private struct arrays { ArrayList nodesMatrix; public ArrayList NodesMatrix { get { return nodesMatrix; } set { nodesMatrix = value; } } List<vertex> vertexMatrix; public List<vertex> VertexMatrix { get { return vertexMatrix; } set { vertexMatrix = value; } } List<bool> odwiedzone; public List<bool> Odwiedzone { get { return odwiedzone; } set { odwiedzone = value; } } public List<element> PriorityQueue { get { return PriorityQueue; } set { PriorityQueue = value; } } } public struct element : IComparable { public double priority { get { return priority; } set { priority = value; } } public int node { get { return node; } set { node = value; } } public element(double _prio, int _node) { priority = _prio; node = _node; } #region IComparable Members public int CompareTo(object obj) { element elem = (element)obj; return priority.CompareTo(elem.priority); } #endregion

• nhibernate/fluenthibernate throws StackOverflowException

  - by Gianluca Colucci

  Hi there! In my project I am using NHibernate/FluentNHibernate, and I am working with two entities, contracts and services. This is my contract type: [Serializable] public partial class TTLCContract { public virtual long? Id { get; set; } // other properties here public virtual Iesi.Collections.Generic.ISet<TTLCService> Services { get; set; } // implementation of Equals // and GetHashCode here } and this is my service type: [Serializable] public partial class TTLCService { public virtual long? Id { get; set; } // other properties here public virtual Activity.Models.TTLCContract Contract { get; set; } // implementation of Equals // and GetHashCode here } Ok, so as you can see, I want my contract object to have many services, and each Service needs to have a reference to the parent Contract. I am using FluentNhibernate. So my mappings file are the following: public TTLCContractMapping() { Table("tab_tlc_contracts"); Id(x => x.Id, "tlc_contract_id"); HasMany(x => x.Services) .Inverse() .Cascade.All() .KeyColumn("tlc_contract_id") .AsSet(); } and public TTLCServiceMapping() { Table("tab_tlc_services"); Id(x => x.Id, "tlc_service_id"); References(x => x.Contract) .Not.Nullable() .Column("tlc_contract_id"); } and here comes my problem: if I retrieve the list of all contracts in the db, it works. if I retrieve the list of all services in a given contract, I get a StackOverflowException.... Do you see anything wrong with what I wrote? Have I made any mistake? Please let me know if you need any additional information. Oh yes, I missed to say... looking at the stacktrace I see the system is loading all the services and then it is loading again the contracts related to those services. I don't really have the necessary experience nor ideas anymore to understand what's going on.. so any help would be really really great! Thanks in advance, Cheers, Gianluca.

• VB.NET 2.0 - StackOverflowException when using Thread Safe calls to Windows Forms Controls

  - by LamdaComplex

  I have a Windows Forms app that, unfortunately, must make calls to controls from a second thread. I've been using the thread-safe pattern described on the http://msdn.microsoft.com/en-us/library/ms171728.aspx. Which has worked great in the past. The specific problem I am having now: I have a WebBrowser control and I'm attempting to invoke the WebBrowser.Navigate() method using this Thread-Safe pattern and as a result I am getting StackOverflow exceptions. Here is the Thread-Safe Navigate method I've written. Private Delegate Sub NavigateControlCallback(ByRef wb As WebBrowser, ByVal url As String) Private Sub AsyncNavigate(ByRef wb As WebBrowser, ByVal URL As String) Try If wb.InvokeRequired Then Dim callback As New NavigateControlCallback(AddressOf AsyncNavigate) callback(wb, url) Else wb.Navigate(url) End If Catch ex As Exception End Try End Sub Is there a Thread-Safe way to interact with WinForms components without the side effect of these StackOverflowExceptions?

• An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll

  - by Tanner

  OK, Im trying to highlight keywords in a richtextbox, the problem is I've got the code to highlight only the visible text on textChanged event,so I tryed putting the code in the richtextbox VScroll, so when I scrolled up it would highlight the text that wasn't visible before, but every time I start to scroll I get this error: "An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll" Does any one know why? Or maybe a way I could highlight the words while scrolling? Thanks, Tanner. int selectionstart = richTextBox1.Selectionstart; int topIndex = richTextBox1.GetCharIndexFromPosition(new Point(1, 1));//This is where I get the error. int bottomIndex = richTextBox1.GetCharIndexFromPosition(new Point(1, richTextBox1.Height - 1)); int topLine = richTextBox1.GetLineFromCharIndex(topIndex); int bottomLine = richTextBox1.GetLineFromCharIndex(bottomIndex); int start = richTextBox1.GetFirstCharIndexFromLine(topLine); int end = richTextBox1.GetFirstCharIndexFromLine(bottomLine); int numLinesDisplayed = (bottomLine - topLine) + 2; richTextBox1.Focus(); richTextBox1.Select(start, end);

• Visual C++/CLI "An unhandled exception of type 'System.StackOverflowException' occurred in"

  - by JennyWong

  Hi, I have a game I am making, it is giving me this message... "An unhandled exception of type 'System.StackOverflowException' occurred in game.exe" To explain...I have a 2D array with 9 different opening moves and I am getting a random number to use as the array reference to retrieve the details needed for a move... you may get the same move again - but that's illegal. the move may be illegal for other reasons too So to try and fix this, I am calling the function again from within the function. The error occurs very randomly Is this bad practise to call a function from within itself? What would be a better way to randomly row from a 2D array, AND if it isn't accept to get another one.... Or better still, how can I retrieve a random LEGAL move?

• C# StackOverflowException

  - by KSwift87

  Problem: I am trying to update a List. If a certain item's ID already exists in the List, I want to add onto that item's quantity. If not, then I want to add another item to the list. cart = (List<OrderItem>)Session["cart"]; for(int counter = cart.Count-1; counter >= 0; counter--) { if (cart[counter].productId == item.productId) { cart[counter].productQuantity += item.productQuantity; } else if (counter == 0) { cart.Add(item); } } "cart[counter]" and "item" represent an instance(s) of a custom object of mine. Currently when I finally find a matching ID, everything APPEARS as though it should work, but I get a StackOverflowException thrown in my custom object class. public int productQuantity { get { return _productQuantity; } set { productQuantity = value; } } It gets thrown right at the open-bracket of the "set". Could somebody please tell me what the heck is wrong because I've been going at this for the past 2+ hours to no avail. Thank you in advance.

• F# Seq.initInfinite giving StackOverflowException

  - by TrueWill

  I'm learning F#, and I am having trouble understanding why this crashes. It's an attempt to solve Project Euler problem 2. let rec fibonacci n = if n = 1 then 1 elif n = 2 then 2 else fibonacci (n - 1) + fibonacci (n - 2) let debugfibonacci n = printfn "CALC: %d" n fibonacci n let isEven n = n % 2 = 0 let isUnderLimit n = n < 55 let getSequence = //[1..30] Seq.initInfinite (fun n -> n) |> Seq.map debugfibonacci |> Seq.filter isEven |> Seq.takeWhile isUnderLimit Seq.iter (fun x -> printfn "%d" x) getSequence The final version would call a sum function (and would have a higher limit than 55), but this is learning code. As is, this gives a StackOverflowException. However, if I comment in the [1..30] and comment out the Seq.initInfinite, I get: CALC: 1 CALC: 2 2 CALC: 3 CALC: 4 CALC: 5 8 CALC: 6 CALC: 7 CALC: 8 34 CALC: 9 CALC: 10 CALC: 11 It appears to be generating items on demand, as I would expect in LINQ. So why does it blow up when used with initInfinite?

• Json.Net Issues: StackOverflowException is thrown when serialising circular dependent ISerializable object with ReferenceLoopHandling.Ignore

  - by keyr

  I have a legacy application that used binary serialisation to persist the data. Now we wanted to use Json.net 4.5 to serialise the data without much changes to the existing classes. Things were working nice till we hit a circular dependent class. Is there any workaround to solve this problem? Sample code as shown below [Serializable] class Department : ISerializable { public Employee Manager { get; set; } public string Name { get; set; } public Department() { } public Department( SerializationInfo info, StreamingContext context ) { Manager = ( Employee )info.GetValue( "Manager", typeof( Employee ) ); Name = ( string )info.GetValue( "Name", typeof( string ) ); } public void GetObjectData( SerializationInfo info, StreamingContext context ) { info.AddValue( "Manager", Manager ); info.AddValue( "Name", Name ); } } [Serializable] class Employee : ISerializable { [NonSerialized] //This does not work [XmlIgnore]//This does not work private Department mDepartment; public Department Department { get { return mDepartment; } set { mDepartment = value; } } public string Name { get; set; } public Employee() { } public Employee( SerializationInfo info, StreamingContext context ) { Department = ( Department )info.GetValue( "Department", typeof( Department ) ); Name = ( string )info.GetValue( "Name", typeof( string ) ); } public void GetObjectData( SerializationInfo info, StreamingContext context ) { info.AddValue( "Department", Department ); info.AddValue( "Name", Name ); } } And the test code Department department = new Department(); department.Name = "Dept1"; Employee emp1 = new Employee { Name = "Emp1", Department = department }; department.Manager = emp1; Employee emp2 = new Employee() { Name = "Emp2", Department = department }; IList<Employee> employees = new List<Employee>(); employees.Add( emp1 ); employees.Add( emp2 ); var memoryStream = new MemoryStream(); var formatter = new BinaryFormatter(); formatter.Serialize( memoryStream, employees ); memoryStream.Seek( 0, SeekOrigin.Begin ); IList<Employee> deserialisedEmployees = formatter.Deserialize( memoryStream ) as IList<Employee>; //Works nicely JsonSerializerSettings jsonSS= new JsonSerializerSettings(); jsonSS.TypeNameHandling = TypeNameHandling.Objects; jsonSS.TypeNameAssemblyFormat = FormatterAssemblyStyle.Full; jsonSS.Formatting = Formatting.Indented; jsonSS.ReferenceLoopHandling = ReferenceLoopHandling.Ignore; //This is not working!! //jsonSS.ReferenceLoopHandling = ReferenceLoopHandling.Serialize; //This is also not working!! jsonSS.PreserveReferencesHandling = PreserveReferencesHandling.All; string jsonAll = JsonConvert.SerializeObject( employees, jsonSS ); //Throws stackoverflow exception Edit1: The issue has been reported to Json (http://json.codeplex.com/workitem/23668)

• An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll

  - by mazhar

  Ok the thing is that I am using asp.net mvc with linq to sql. I have a scenario where there are two tables group and features with many to many relationship with the third table groupfeatures. I have drag and drop all three table in the dbml file. The thing is that it runs fine with group but when I call the Feature things the above error occured and the compilers stops at this line in ((())). public partial class EgovtDataContext : System.Data.Linq.DataContext { private static System.Data.Linq.Mapping.MappingSource mappingSource = new AttributeMappingSource(); #region Extensibility Method Definitions partial void OnCreated(); partial void InsertGroup(Group instance); partial void UpdateGroup(Group instance); partial void DeleteGroup(Group instance); partial void InsertFeature(Feature instance); partial void UpdateFeature(Feature instance); partial void DeleteFeature(Feature instance); partial void InsertGroupFeature(GroupFeature instance); partial void UpdateGroupFeature(GroupFeature instance); partial void DeleteGroupFeature(GroupFeature instance); #endregion (((public EgovtDataContext() : base(global::System.Configuration.ConfigurationManager.ConnectionStrings["egovtsConnectionString"].ConnectionString, mappingSource)))) The code in both the controller Group and features file is ditto copied. Note the group things are working, the features things are not. FeaturesRepository.cs public IQueryable<Feature> FindAllFeatures() { return db.Features; } FeaturesController.cs FeaturesRepository FeatureRepository = new FeaturesRepository(); public ActionResult Index() { var Feature = FeatureRepository.FindAllFeatures(); return View(Feature); } So what could be wrong?

• NHibernate ManyToMany Relationship Cascading AllDeleteOrphan StackOverflowException

  - by Chris

  I have two objects that have a ManyToMany relationship with one another through a mapping table. Though, when I try to save it, I get a stack overflow exception. The following is the code for the mappings: //EventMapping.cs HasManyToMany(x => x.Performers).Table("EventPerformer").Inverse().Cascade.AllDeleteOrphan().LazyLoad().ParentKeyColumn("EventId").ChildKeyColumn("PerformerId"); //PerformerMapping.cs HasManyToMany<Event>(x => x.Events).Table("EventPerformer").Inverse().Cascade.AllDeleteOrphan().LazyLoad().ParentKeyColumn("PerformerId").ChildKeyColumn("EventId"); When I change the performermapping.cs to Cascade.None() I get rid of the exception but then my Event Object doesn't have the performer I associate with it. //In a unit test, paraphrased event.Performers.Add(performer); //Event eventRepository.Save<Event>(event); eventResult = eventRepository.GetById<Event>(event.id); //Event eventResult.Performers[0]; //is null, should have performer in it How should I be writing this properly? Thanks

• StackOverflowException in c# when no local variable in the function

  - by dnkulkarni

  when i do this static void Main() { Main(); } I receive stackoverflow exception. As i have read so far about C# they say ONLY local variable of value types (and short living ones) will go on stack. But here in the code there are no local variable to go on stack then what overflows it ? I know from assembly code line Perspective that reference to Main() will go on stack too ? Is that right ?

• Recursive QuickSort suffering a StackOverflowException -- Need fresh eyes

  - by jon

  I am working on a Recursive QuickSort method implementation in a GenericList Class. I will have a second method that accepts a compareDelegate to compare different types, but for development purposes I'm sorting a GenericList<int I am recieving stackoverflow areas in different places depending on the list size. I've been staring at and tracing through this code for hours and probably just need a fresh pair of (more experienced)eyes. Definitely wanting to learn why it is broken, not just how to fix it. public void QuickSort() { int i, j, lowPos, highPos, pivot; GenericList<T> leftList = new GenericList<T>(); GenericList<T> rightList = new GenericList<T>(); GenericList<T> tempList = new GenericList<T>(); lowPos = 1; highPos = this.Count; if (lowPos < highPos) { pivot = (lowPos + highPos) / 2; for (i = 1; i <= highPos; i++) { if (this[i].CompareTo(this[pivot]) <= 0) leftList.Add(this[i]); else rightList.Add(this[i]); } leftList.QuickSort(); rightList.QuickSort(); for(i=1;i<=leftList.Count;i++) tempList.Add(leftList[i]); for(i=1;i<=rightList.Count;i++) tempList.Add(rightList[i]); this.items = tempList.items; this.count = tempList.count; } }

• Suggestion for chkstk.asm stackoverfolw exception in C++ with Visual Studio 2010

  - by Gulshan

  I am working with an implementation of merge sort. I am doing C++ Visual Studio 2010. But when I took a array of 300000 integers for timing, it is showing an unhandled stackoverflow exception and taking me to a readonly file named "chkstk.asm". I reduced the size to 200000 and it worked. Again the same code worked with C-free 4 editor (mingw 2.95) without any problem while the size was 400000. Do you have any suggestion to get the code working in Visual Studio? May be the recursion in the mergesort is causing the problem.

• Tracking Down a Stack Overflow in My Linq Query

  - by Lazarus

  I've written the following Linq query: IQueryable<ISOCountry> entries = (from e in competitorRepository.Competitors join c in countries on e.countryID equals c.isoCountryCode where !e.Deleted orderby c.isoCountryCode select new ISOCountry() { isoCountryCode = e.countryID, Name = c.Name }).Distinct(); The objective is to retrieve a list of the countries represented by the competitors found in the system. 'countries' is an array of ISOCountry objects explicitly created and returned as an IQueryable (ISOCountry is an object of just two strings, isoCountryCode and Name). Competitors is an IQueryable which is bound to a database table through Linq2SQL though I created the objects from scratch and used the Linq data mapping decorators. For some reason this query causes a stack overflow when the system tries to execute it. I've no idea why, I've tried trimming the Distinct, returning an anonymous type of the two strings, using 'select c', all result in the overflow. The e.CountryID value is populated from a dropdown that was in itself populated from the IQueryable so I know the values are appropriate but even if not I wouldn't expect a stack overflow. Can anyone explain why the overflow is occurring or give good speculation as to why it might be happening? EDIT As requested, code for ISOCountry: public class ISOCountry { public string isoCountryCode { get; set; } public string Name { get; set; } }
