  • Set up tunnel to HE.net and now only ipv6.google.com works, but other sites ping fine.

    - by AndrejaKo
    I'm setting up IPv6 using my router which is running OpenWRT, version Backfire 10.03.1-rc4. I made a tunnel using Hurricane Electric's tunnel broker and set it up on the router and I'm using RADVD to hand out IPv6 addresses. My problem is that on computers on the network, I can only access ipv6.google.com using a browser, but other sites seem to be loading forever and won't open in any browser. I can ping and traceroute to them fine, but can't open them with a browser. I can open any site normally with a browser from the router. Stopping firewall service on the router doesn't help, so it's probably not a firewall issue. All AAAA records resolve fine, so it's probably not a DNS issue. Computers on the network get their IPv6 addresses fine, so it's probably not a radvd issue. Similar setup worked fine for SixXs, but I'm having problems with my PoP there, so I decided to move to HE. Here are some traceroutes: From a client computer: Tracing route to ipv6.he.net [2001:470:0:64::2] over a maximum of 30 hops: 1 <1 ms 1 ms 1 ms 2001:470:1f0b:de5::1 2 62 ms 63 ms 62 ms andrejako-1.tunnel.tserv6.fra1.ipv6.he.net [2001:470:1f0a:de5::1] 3 60 ms 60 ms 63 ms gige-g2-4.core1.fra1.he.net [2001:470:0:69::1] 4 63 ms 68 ms 68 ms 10gigabitethernet1-4.core1.ams1.he.net [2001:470:0:47::1] 5 84 ms 74 ms 76 ms 10gigabitethernet1-4.core1.lon1.he.net [2001:470:0:3f::1] 6 146 ms 147 ms 151 ms 10gigabitethernet4-4.core1.nyc4.he.net [2001:470:0:128::1] 7 200 ms 198 ms 202 ms 10gigabitethernet5-3.core1.lax1.he.net [2001:470:0:10e::1] 8 219 ms * 210 ms 10gigabitethernet2-2.core1.fmt2.he.net [2001:470:0:18d::1] 9 221 ms 338 ms 209 ms gige-g4-18.core1.fmt1.he.net [2001:470:0:2d::1] 10 206 ms 210 ms 207 ms ipv6.he.net [2001:470:0:64::2] Trace complete. and another from a cliet computer Tracing route to whatismyipv6.com [2001:4870:a24f:2::90] over a maximum of 30 hops: 1 7 ms 1 ms 1 ms 2001:470:1f0b:de5::1 2 69 ms 70 ms 63 ms AndrejaKo-1.tunnel.tserv6.fra1.ipv6.he.net [2001:470:1f0a:de5::1] 3 57 ms 65 ms 58 ms gige-g2-4.core1.fra1.he.net [2001:470:0:69::1] 4 73 ms 74 ms 75 ms 10gigabitethernet1-4.core1.ams1.he.net [2001:470:0:47::1] 5 71 ms 74 ms 76 ms 10gigabitethernet1-4.core1.lon1.he.net [2001:470:0:3f::1] 6 141 ms 149 ms 148 ms 10gigabitethernet2-3.core1.nyc4.he.net [2001:470:0:3e::1] 7 141 ms 147 ms 143 ms 10gigabitethernet1-2.core1.nyc1.he.net [2001:470:0:37::2] 8 144 ms 145 ms 142 ms 2001:504:1::a500:4323:1 9 226 ms 225 ms 218 ms 2001:4870:a240::2 10 220 ms 224 ms 219 ms 2001:4870:a240::2 11 219 ms 218 ms 220 ms 2001:4870:a24f::2 12 221 ms 222 ms 220 ms www.whatismyipv6.com [2001:4870:a24f:2::90] Trace complete.

  • Update EntitySet<> LINQ to SQL references

    - by gtas
    I know that when attaching an entity into a DataContext you have to also attach the related referenced objects manually too. While I'm attaching the EntityRef<'s everything works as expected and my entities are updated to the database. But i have noticed that a problem occurs while trying to attach the EntitySet<'s. I dont use rowversion columns so I'm attaching for every entity on the EntitySet< using original values. Tried just attaching AttachAll() the EntitySet< with no luck and no exception too. There is no exception but the update is not really happening. What am i missing?

  • .NET COM Interop with references to other libraries

    - by user262190
    Hello,I'm up against a problem when loading a class in a managed library from a COM Interop library. basically I have some Unmanaged C++ code and a COM Interop library written in C#. And finally a 3rd library which is referenced by the COM Interop library which contains a class: public class MyClass{ public MyClass(){} } What I'd like to do is from my unmanaged c++ code, call a function in the Interop library The C++ code doesn't need to know of the existence of the third library, it's only used within the Interop. Init(){ MyClass _class = new MyClass(); } for some reason this line in Init fails "MyClass _class = new MyClass();", and I don't get very usefull error messages, all I have to go on is a few of these in my output window: "First-chance exception at 0x7c812afb in DotNet_Com_Call.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.." and the HRESULT of the "HRESULT hr = pDotNetCOMPtr-Init();" line in my C++ code is "The system cannot find the specified file" I'm new to COM so if anyone has any ideas or pointer to get me going the right direction, I'd appreciate it, Thanks

  • HTTP Authentication with Web References

    - by Thor
    I have a web reference created from the WSDL, but I'm not allowed to call the function unless I pass in the username / password; the original code for the XML toolkit was: Set client = CreateObject("MSSOAP.SOAPClient30") URL = "http://" & host & "/_common/webservices/Trend?wsdl" client.mssoapinit (URL) client.ConnectorProperty("WinHTTPAuthScheme") = 1 client.ConnectorProperty("AuthUser") = user client.ConnectorProperty("AuthPassword") = passwd On Error GoTo err Dim result1() As String result1 = client.getTrendData(expression, startDate, endDate, limitFromStart, maxRecords How do I add the AuthUser/AuthPassword to my new code? New code: ALCServer.TrendClient tc = new WindowsFormsApplication1.ALCServer.TrendClient(); foreach(string s in tc.getTrendData(textBox2.Text, "5/25/2009", "5/28/2009", false, 500)) textBox1.Text+= s;

  • keeping references to inflated custom views

    - by darren
    Hi While researching how to create custom compound views in Android, I have come across this pattern a lot (example comes from the Jteam blog) : public class FirstTab extends LinearLayout { private ImageView imageView; private TextView textView; private TextView anotherTextView; public FirstTab(Context context, AttributeSet attributeSet) { super(context, attributeSet); LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); inflater.inflate(R.layout.firstTab, this); } } I mostly understand how this is working, except for the part where inflate() is called. The documentation says that this method returns a View object, but in this example the author does not store the result anywhere. After inflation, how is the new View created fromt eh XML associated with this class? I thought about assigning it to "this", but that seems very wrong. thanks for any clarification.

  • ELF: linking: Why do I get undefined references in .so files

    - by ki.lya.online.fr
    Hi, I'm trying to build a program against wxWidgets, and I get a linker error. I'd like to really understand what it means. The error is: /usr/lib/libwx_baseu-2.8.so: undefined reference to `std::ctype<char>::_M_widen_init() const@GLIBCXX_3.4.11' What I don't understand is why the error is at libwx_baseu-2.8.so. I thought that .so files had all its symbols resolved, contrary to .o files that still need linking. When I ldd the .so, I get can resolve all its linked libraries, so there is no problem there: $ ldd /usr/lib/libwx_baseu-2.8.so linux-gate.so.1 => (0x00476000) libz.so.1 => /lib/libz.so.1 (0x00d9c000) libdl.so.2 => /lib/libdl.so.2 (0x002a8000) libm.so.6 => /lib/libm.so.6 (0x00759000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x002ad000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x0068d000) libpthread.so.0 => /lib/libpthread.so.0 (0x006f0000) libc.so.6 => /lib/libc.so.6 (0x00477000) /lib/ld-linux.so.2 (0x007f6000) Does it means that the .so file was not compiled correctly (in that case, it's a bug in my distribution package) or does it means that there are missing libraries on the linker command line for my particular program? Additionally, do you know how I can get a list on undefined symbols in an ELF file. I tried readelf -s but I can't find the missing symbol. Thank you. Mildred

  • How can I get PowerShell Added-Types to use Added References

    - by Scott Weinstein
    I'm working on a PoSh project that generates CSharp code, and then Add-Types it into memory. The new types use existing types in an on disk DLL, which is loaded via Add-Type. All is well and good untill I actualy try to invoke methods on the new types. Here's an example of what I'm doing: $PWD = "." rm -Force $PWD\TestClassOne* $code = " namespace TEST{ public class TestClassOne { public int DoNothing() { return 1; } } }" $code | Out-File tcone.cs Add-Type -OutputAssembly $PWD\TestClassOne.dll -OutputType Library -Path $PWD\tcone.cs Add-Type -Path $PWD\TestClassOne.dll $a = New-Object TEST.TestClassOne "Using TestClassOne" $a.DoNothing() "Compiling TestClassTwo" Add-Type -Language CSharpVersion3 -TypeDefinition " namespace TEST{ public class TestClassTwo { public int CallTestClassOne() { var a = new TEST.TestClassOne(); return a.DoNothing(); } } }" -ReferencedAssemblies $PWD\TestClassOne.dll "OK" $b = New-Object TEST.TestClassTwo "Using TestClassTwo" $b.CallTestClassOne() Running the above script gives the following error on the last line: Exception calling "CallTestClassOne" with "0" argument(s): "Could not load file or assembly 'TestClassOne,...' or one of its dependencies. The system cannot find the file specified." At AddTypeTest.ps1:39 char:20 + $b.CallTestClassOne <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException What am I doing wrong?

  • What are the best Perl Introductions and references?

    - by Kieveli
    I've been programming for 15+ years, and I've done perl programming 3 times in the past. Every time I come back to it, I remember nothing of the language. It's very bizarre. Now it's time to hit perl again, and I'm wondering what the best Intro / Reference / Best Practice sites are that people use. Which Perl Intro / Reference site do you recommend?

  • Attribute References in Python

    - by Jeune
    I do Java programming and recently started learning Python via the official documentation. I see that we can dynamically add data attributes to an instance object unlike in Java: class House: pass my_house = House() my_house.number = 40 my_house.rooms = 8 my_house.garden = 1 My question is, in what situations is this feature used? What are the advantages and disadvantages compared to the way it is done in Java?

  • Using Linq methods causes missing references to DependencyObject in WindowsBase

    - by Jason Coyne
    I have some c# source that I want to compile using CodeDom within my application (for a plugin) Everything works fine, except if I use a Linq extension function on some of my collections var dict = new Dictionary<KeyType, ValueType>(); .... dict.Any(KV=>KV.Key == "Some Key); When I try to compile source that has this code, it CodeDom complains that I am missing a reference to DependencyObject in WindowsBase. I do not understand why this is happening. Neither the Dictionary class, or the Any extension method reference that class, which apparently is part of Windows.Forms I would normally just ignore the quirk, make the CodeDom add a reference and move on, but Apparently WindowsBase is special and is not always distributed and I don't want to cause issues for users that may not have it installed correctly.

  • Const references when dereferencing iterator on set, starting from Visual Studio 2010

    - by Patrick
    Starting from Visual Studio 2010, iterating over a set seems to return an iterator that dereferences the data as 'const data' instead of non-const. The following code is an example of something that does compile on Visual Studio 2005, but not on 2010 (this is an artificial example, but clearly illustrates the problem we found on our own code). In this example, I have a class that stores a position together with a temperature. I define comparison operators (not all them, just enough to illustrate the problem) that only use the position, not the temperature. The point is that for me two instances are identical if the position is identical; I don't care about the temperature. #include <set> class DataPoint { public: DataPoint (int x, int y) : m_x(x), m_y(y), m_temperature(0) {} void setTemperature(double t) {m_temperature = t;} bool operator<(const DataPoint& rhs) const { if (m_x==rhs.m_x) return m_y<rhs.m_y; else return m_x<rhs.m_x; } bool operator==(const DataPoint& rhs) const { if (m_x!=rhs.m_x) return false; if (m_y!=rhs.m_y) return false; return true; } private: int m_x; int m_y; double m_temperature; }; typedef std::set<DataPoint> DataPointCollection; void main(void) { DataPointCollection points; points.insert (DataPoint(1,1)); points.insert (DataPoint(1,1)); points.insert (DataPoint(1,2)); points.insert (DataPoint(1,3)); points.insert (DataPoint(1,1)); for (DataPointCollection::iterator it=points.begin();it!=points.end();++it) { DataPoint &point = *it; point.setTemperature(10); } } In the main routine I have a set to which I add some points. To check the correctness of the comparison operator, I add data points with the same position multiple times. When writing the contents of the set, I can clearly see there are only 3 points in the set. The for-loop loops over the set, and sets the temperature. Logically this is allowed, since the temperature is not used in the comparison operators. This code compiles correctly in Visual Studio 2005, but gives compilation errors in Visual Studio 2010 on the following line (in the for-loop): DataPoint &point = *it; The error given is that it can't assign a "const DataPoint" to a [non-const] "DataPoint &". It seems that you have no decent (= non-dirty) way of writing this code in VS2010 if you have a comparison operator that only compares parts of the data members. Possible solutions are: Adding a const-cast to the line where it gives an error Making temperature mutable and making setTemperature a const method But to me both solutions seem rather 'dirty'. It looks like the C++ standards committee overlooked this situation. Or not? What are clean solutions to solve this problem? Did some of you encounter this same problem and how did you solve it?

  • eXML-PARSER output contains unwanted hash references

    - by seaworthy
    So I wrote a parser routine to take one xml file and reparse into another one. This code I later modified to split a large xml file into many small xml files.

  • castle IOC - resolving circular references

    - by Frederik
    Hi quick question for my MVP implementation: currently I have the code below, in which both the presenter and view are resolved via the container. Then the presenter calls View.Init to pass himself to the view. I was wondering however if there is a way to let the container fix my circular reference (view - presenter, presenter - view). class Presenter : IPresenter { private View _view; public Presenter(IView view, ...){ _view = view; _view.Init(this) } } class View : IView { private IPresenter _presenter; public void Init(IPresenter presenter){ _presenter = presenter; } } Kind regards Frederik

  • HttpModule to Write Out JavaScript Script References to the Response

    - by Chris
    On my page in the Page_Load event I add a collection of strings to the Context object. I have an HttpModule that will fire EndRequest and retrieve the collection of strings. What I then do is write out a script reference tag (based on the collection of strings) to the response. The problem is that the page reads the script reference but doesn't retrieve the contents of the file (I imagine because this is occurring in the EndRequest event). I can't fire the BeginRequest event because I won't have access to the Context Items collection. I tried to also registering an HttpHandler which Processes the request of the script reference but I can't access the collection of strings in the Context.Items from there. Any suggestions? Page_Load: protected void Page_Load(object sender, EventArgs e) { Context.Items.Add("ScriptFile", "/UserControls.js"); } HttpModule: public void OnEndRequest(Object s, EventArgs e) { HttpApplication app = s as HttpApplication; object script = app.Context.Items["ScriptFile"]; app.Response.Write("<script type='text/javascript' src='" + script + "'></script>"); }

  • How to avoid game rendering component circular references?

    - by CodexArcanum
    I'm working on a simple game design, and I wanted to break up my game objects into more reusable components. But I'm getting stuck on how exactly to implement the design I have in mind. Here's an example: I have a Logger object, whose job is simply to store a list of messages and render them to screen. You know, logging. Originally the Logger just held the list, and the game loop rendered it's contents. Then I moved the rendering logic into the Logger.Draw() method, and now I want to move it further into a LoggerRenderer object. In effect, I want to have the game loop call RenderAll, which will then call Logger.Render, which will in turn call the LoggerRenderer.Render and finally output the text. So the Logger needs to contain a Renderer object, but the Renderer needs access to the Logger's state (the message queue) in order to render. How do I resolve that? Should I be passing in the message queue and other state information explicitly to the Render method? Or should the game loop be calling the Renderer directly and it links back to the logger, but the RenderAll method never actually sees the logger object itself? This feels kind of like Command pattern, but I'm botching it up terribly.

  • undefined references

    - by Brandon
    Hello, I'm trying to compile some fortran code and I'm running into some confusing linking errors. I have some code that I compile and place into a static library: >gfortran -c -I../../inc -o bdout.o bdout.F >ar rv libgeo.a bdout.o I then try to compile against that library with some simple test code and get the following: >gfortran -o mytest -L -lgeo mytest.F /tmp/cc4uvcsj.o: In function `MAIN__': mytest.F:(.text+0xb0): undefined reference to `ncwrite1_' collect2: ld returned 1 exit status It's not in the object naming because everything looks fine: >nm -u libgeo.a bdout.o: U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ I can check the original object file too: >nm -u bdout.o U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ The test code simply contains a single call to a function defined in bdout.o: program hello print *,"Hello World!" call ncwrite1( istat, f, ix2, ix3, ix4, ix5, ih ) end program hello I can't figure out what the problem is. Does anyone have any suggestions? Maybe even just a way to track the problem down? Cheers.

  • Problem with persisting a collection, that references an internal property, at design time in winfor

    - by Jules
    ETA: Jesus, I'm sick of this. This problem was specifically about persisting an interface collection but now on further testing it doesn't work for a normal collection. Here's some even simpler code: Public Class Anger End Class Public Class MyButton Inherits Button Private _Annoyance As List(Of Anger) <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As List(Of Anger) Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New List(Of Anger) Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class The designer screws up the persistence code in the same way as the original problem. ---- Original Problem The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?
