• Why packets injected with libpcap are duplicated?

  - by r0u1i

  I'm using sharppcap in order to send packets as part of a monitoring system. Usually it works well but I've encountered the strangest bug on a hosted vista machine and I would like your help. On that virtual vista machine, injected packets are duplicated. That is, if I send a ping request using libpcap, it somehow gets duplicated and I get two requests on the destination machine. The two requests are almost identical byte-wise, and the only difference between them is that the second packet's TTL field is one minus the original packet's value. Using wireshark I can see the packet gets duplicated before it (and its clone) leave the vista machine. The problem is manifested even when using other tools for injecting packets using libpcap (namely PlayCap). Any ideas?

• NHibernate Validator - how to validate enum type

  - by Herr W.

  I'm using nhibernate validator in my current solution. Everythings is almost fine but... My view model has a property of type Gender (see example below) public virtual Gender Gender { get; set; } public enum Gender { Female = 1, Male = 2 } Now i like to have some validation to ensure that the gender property ist set. But neither the NotEmpty nor the NotNull Attribute fulfil the requirement. Is there a kind of a generic solution or best practice to handle enum validations. Thanks in advance.

• allowDefinition='MachineToApplication' error when publishing from VS2010 (but only after a previous

  - by burnt_hand

  I can run my Asp.Net MVC 2 application without an issue on my local computer. Just Run / Debug. But if I have already built it, I can't publish it! I have to clean the solution and publish it again. I know this is not system critical, but it's really annoying. "One Click Publish" is not "Clean solution and then One click publish" The exact error is as follows: Error 11 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. I suspect it's something to do with the Web.Config in the Views folder, but then why only after I build once previously. And just to note, the app works fine once published.

• Dns caching for sockets

  - by Poma

  I'm connecting to some websites through socks proxy server. In my case its very good to implement dns cache, so proxy don't need to resolve website's ip address. So, I performed DNS lookup, but don't know where to supply IP address. mySocket.Connect uses proxy's ip address so it isn't right place. I tried to place it in http header GET http://11.22.33.44/index.html HTTP/1.1 - this doesn't work (even in browser) since website is on virtual hosting. It seems that Host header is right place for resolved ip address. Am I right? Will proxy resolve host name (since it's still there in GET header) or not?

• Delphi 2010: whatever happened to TRTTIConstructor?

  - by conciliator

  I've got two questions (of which at least one is regarding RTTI in D2010 and dynamic instancing) I was reading what appears to be the foils for a conference talk by Barry Kelly, and found on p. 13 something that looked really interesting: TRTTIConstructor.Invoke. In an adjacent bullet point, on finds "Dynamically construct instances without needing virtual constructors and metaclasses". This seems like a great feature (and exactly what I need, btw)! However, when I look in the D2010 docs (ms-help://embarcadero.rs2010/vcl/Rtti.html), I can't find it. Did it get revoked? What is the minimal way of creating an instance of a class, provided the class name is stored in a string?

• c++ webservice having problems with Mozilla Firefox browser

  - by prasanna

  Hi , About Problem:- We have a webservice written in c++.And we use cgi scripts in HTML pages to run our own exe which will output HTML. With IE i am not seeing any problem. But With Mozilla FireFox 3.0 there is error showing up as " You have chosen to open gefebt.exe which is a : Application from http:\3.212.219.180\test Would you like to save this file" Also i did some investigation :- i have created a virtual directory using IIS where when i click hyperlink i have made gefebt.exe to execute. With IIS there is no problem untill Execute Permissions is set to "Scripts and Executables" . If i select scripts i could see the same message in IE and mozilla plugin. At the same time i not seeing any difference with the code of Webservice. The way we are reffering the executable in HTML is href=gefebt.exe?xyz.bclInvoke xyz.bcl - I have also tries with IFrames and frames .

• xval get message from resource file

  - by Rob

  I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this? Below the code which should make the relation to the resourcefile en specify the error when the field is left empty. [Property] [Required(ErrorMessageResourceType = typeof(CMSMessages), ErrorMessageResourceName = "EnterValidMoney")] public virtual Double ShippingCost { get; set; }

• Drag and Drop to explorer causing invalid FORMATETC (DV_E_FORMATETC) error

  - by JustABill

  I'm trying to use this excellent example to implement dropping virtual files into Windows Explorer. However, I'm stymied by this error. Towards the bottom, inside void System.Runtime.InteropServices.ComTypes.IDataObject.GetData(ref System.Runtime.InteropServices.ComTypes.FORMATETC formatetc, out System.Runtime.InteropServices.ComTypes.STGMEDIUM medium) on the first call to ((System.Runtime.InteropServices.ComTypes.IDataObject)this).GetDataHere(ref formatetc, ref medium); I'm getting back a DV_E_FORMATETC error. As far as I can tell, all the elements of the FORMATETC struct that are being passed in are valid: cfFormat is "Shell IDList Array" (-16141), ptd is 0, dwAspect is DVASPECT_CONTENT, lindex is -1, and tymed is TYMED_HGLOBAL. I'm kind of confused how there'd be a problem anyway, since this was generated by explorer. I know very little about COM interaction, so any help would be greatly appreciated.

• Why is the modal dialog in MFC actually internally modeless?

  - by pythiyam

  This question arose in my miind after reading this article: http://www.codeproject.com/Articles/3911/The-singular-non-modality-of-MFC-modal-dialogs. He mentions that the modal dialog in MFC is not strictly modal, but implemented as a modeless dialog(internally) with bells and whistles to make it behave as a modal one. Specifically, he says: The MFC command routing mechanism uses a combination of message maps and virtual functions to achieve what it does and a true modal dialog will totally wreck this mechanism because then the modal message loop is controlled outside the scope of the MFC command routing machinery Could anyone elucidate this statement? An example of what would have gone wrong if they had tried to implement a truly modal dialog would greatly clear things up.

• Redirect away from HTTPS with ASP.NET MVC App

  - by Amadiere

  I'm using ASP.NET MVC 2 and have a login page that is secured via HTTPS. To ensure that the user always accesses those pages via SSL, I've added the attribute [RequiresHttps] to the controller. This does the job perfectly. When they have successfully logged in, I'd like to redirect them back to HTTP version. However, there isn't a [RequiresHttp] attribute and I'm struggling to get my head around how I might achieve this. The added (potential) complication is that the website when in production is hosted at the route of the domain, but for development and testing purposes it is within a sub directory / virtual directory / application. Am I over-thinking this and is there an easy solution staring me in the face? Or is it a little more complex?

• Java bytecode compiler benchmarks

  - by Dave Jarvis

  Q.1. What free compiler produces the fastest executable Java bytecode? Q.2. What free virtual machine executes Java bytecode the fastest (on 64-bit multi-core CPUs)? Q.3. What other (currently active) compiler projects are missing from this list: http://www.ibm.com/developerworks/java/jdk/ http://gcc.gnu.org/java/ http://openjdk.java.net/groups/compiler/ http://java.sun.com/javase/downloads/ http://download.eclipse.org/eclipse/downloads/ Q.4. What performance improvements can compilers do that JITs cannot (or do not)? Q.5. Where are some recent benchmarks, comparisons, or shoot-outs (for Q1 or Q2)? Thank you!

• Redirect Using htaccess

  - by manyxcxi

  I am trying to redirect /folder to / using .htaccess but all am I getting is the Apache HTTP Server Test Page. My root directory looks like this: / .htaccess -/folder -/folder2 -/folder3 My .htaccess looks like this: RewriteEngine On RewriteCond %{REQUEST_URI} !^/folder/ RewriteRule ^(.*)$ folder/$1 [L] What am I doing wrong? I checked my httpd.conf (I'm running Centos 5.3) and the mod_rewrite library is being loaded. As a side note, my server is not a www server, its simply a virtual machine so its hostname is centosvm. Addition: I have found that the mod_rewrite module is loaded, but none of my .htaccess redirects seem to be working.

• Marshal a C++ class to C#

  - by Adam Haile

  I need to access code in a native C++ DLL in some C# code but am having issues figuring out the marshaling. I've done this before with code that was straight C, but seem to have found that it's not directly possible with C++ classes. Made even more complicated by the fact that many of the classes contain virtual or inline functions. I even tried passing the headers through the PInvoke Interop Assistant, but it would choke on just about everything and not really no what to do... I'm guessing because it's not really supported. So how, if at all possible, can you use a native C++ class DLL from .NET code. If I have to use some intermediary (CLR C++?) that's fine.

• Fluent Nhibernate expression to select on flagged enum

  - by mbalkema

  I have a domain entity that has a flagged enum as a property. The flagged enum is the target audience for the these entities. The user then has a flagged enum value of the entities they should see. I am trying to figure out the correct expression to select entities that meet the target audience for the user. public class File { public virtual TargetAudience TargetAudience { get; set; } } [Flags] public enum TargetAudience { Audience1 = 1, Audience2 = 2, Audience3 = 4, Audience4 = 8 } Expression: (This works when performed on a IList<File>, but doesn't work on a query to the database.) public Expression<Func<File, bool>> Expression { get { return ((x.TargetAudience & UserTargetedAudience) > 0); } } Any suggestions would be helpful.

• MIDI on Android: Java and/or AIR libraries

  - by yar

  I've been contemplating (re)building an app on iPad for some time, where I would use objective-C and DSMI to send MIDI signals to a host computer. This is not bad (I mean, except for actually writing the app). Now I'm contemplating perhaps developing the app for Android tablets (TBA). In Java, what options are available for MIDI message communication? I'm quite familiar with javax.sound.midi, but then I would need a virtual MIDI port to send messages to the host. On the other hand, if the app were done in Adobe AIR, what options would I have available for communicating with MIDI? Obviously another option is to send/receive messages over a TCP/IP socket to a Java host, and talk that way, but it sounds a tad cumbersome... or perhaps not? DSMI does use a host program, after all.

• Other users on my Server?

  - by Jennifer Weinberg

  I'm buying a Server from a person (that I don't know really well) and I want to make sure that the previous owner hasn't got any access anymore. It's an Ubuntu Virtual Server and I already received the admin access (via shell). How can I find out if there are still other accounts left, who are still able to access my server (e.g. with a still existing shell account, ftp or another type of user account)? And how can I delete them if these accounts exist? Best regards, Jennifer

  So for my programming class we have had a project to create a virtual machine including a memory unit, cpu, Input, Output, Instruction Register, Program Counter, MAR, MDR and so on. Now we need to create a compiler using Java Code that will take a .exe file written in some txt editor and convert it to java byte code and run the code. The code we will be writing in the .exe file is machine code along the lines of: IN X IN Y ADD X STO Y OUT Y STOP DC X 0 DC Y 0 I am just a beginner and only have 2 days to write this and am very lost and have no idea where to start....Any Help will be much appreciated.

• IIS 6.0 - ASP Error 0126 Include file not found

  - by André

  Hello, I have a Win Sever 2003 running IIS 6.0 which has only my main website on it and now I am trying to setup a test website which currently is an exact duplicate of the main site. When accessing my main site everything works fine, and has done for a long time. If I access the test site (through 'test.' subdomain) I get this error: Active Server Pages error 'ASP 0126' Include file not found /html/shop/asp/admin/inc/incWeeklySpecialswide3.asp, line 71 The include file '/html/asp/quickfindwithSuburbs31.asp' was not found. The file actually exists, and the paths are correct. I have enabled Parent Paths, replaced the include file path to the full path (http://foo.com/html/asp -etc.), removing the ' / ' at the start of the path and changing the code from ' include ' to ' virtual '. Thanks in advance.

• ASP.NET How expensive is it to call an Application Variable many times?

  - by Matias Nino

  The short of it is: Is it costly to check an Application Variable such as Application("WebAppName") more 10-20 times each time a page loads? Background: (feel free to critique) Some includes in my site contain many links and images which cannot use relative urls due to their inclusion in different paths. Hence these includes contain frequent instances of <img src="<%=Application("Webroot")%>images\image.gif"> Is it expensive to keep calling an Application variable like this? Should I just put the Application value in some local variable to use where needed? IMPORTANT NOTE: I need my webapp to run fine on a server whether it be in the root web ("/") or in a virtual subweb ("/app"). Thanks in advance for any wisdom shared.

• CrossDomain error

  - by Jayesh

  Hi, I have hosted my Silverlight application in IIS, now when I try to access the application I get the following error System.ServiceModel.CommunicationException: an error occured while trying to make request to URI This could be due to attempting to access a service in a cross-domain way without proper cross-domain policy in place, or policy that is unsuitable for SOAP services..... I have placed the cross-domain policy properly in wwwroot as well as in the virtual directory. <?xml version="1.0"?> <cross-domain-policy> <allow-http-request-headers-from domain="*" headers="*"/> </cross-domain-policy> Please help! Thanks

• Can Fluent nhibernate's automapper be configured to handle private readonly backing fields?

  - by Mark Rogers

  I like private readonly backing fields because some objects are mostly read-only after creation, and for collections, which rarely need to be set wholesale (instead using collection methods to modify the collection). For example: public class BuildingType : DomainEntity { /* rest of class */ public IEnumerable<ActionType> ActionsGranted { get { return _actionsGranted; } } private readonly IList<ActionType> _actionsGranted = new List<ActionType>(); private readonly Image _buildingTile; public virtual Image BuildingTile { get { return _buildingTile; } } } But as far as I remember fluent-nhibernate's automapper never had a solution for private readonly backing fields, I'm wondering if that's changed in the last few months. So here's my question: How do I configure automapper or create an automapping convention to map private readonly backing fields?

• InvalidOperationException When XML Serializing Inherited Class

  - by Nick

  I am having an issue serializing a c# class to an XML file that has a base class... here is a simple example: namespace Domain { [Serializable] public class ClassA { public virtual int MyProperty { get; set; } } } namespace Derived { public class ClassA : Domain.ClassA { public override int MyProperty { get { return 1; } set { /* Do Nothing */ } } } } When I attempt to serialize an instance of Derived.ClassA, I receive the following exception: InvalidOperationException(Types 'Domain.ClassA' and 'Derived.ClassA' both use the XML type name 'ClassA', from the namespace ". Use XML attributes to specify a unique XML name and/or namespace for the type.) The problem is that I want to create a single base class that simply defines the structure of the XML file, and then allow anyone else to derive from that class to insert business rules, but that the formatting will come through from the base. Is this possible, and if so, how do I attribute the base class to allow this?
