• extracting SWF gives compiler errors in adobe flash CS4

  - by Andy

  Hey, I have been given an SWF to edit a link in the AS code. The fact is the SWF uses some XML that is generated (actually retrieved) by PHP code from a database. menuXML.load("/sub/page/dynamic.php?genre=" + genre); so the point is we can use the same SWF 'mainfraim' and fill them with different animations/sources based on the link provided in dynamic.php?genre=### Now, I've used Flash Decompiler Gold to extract all files in the SWF and can open it again in Adobe Flash to edit it. When done I enter CTRL+ENTER and there are immediately 4 compiler errors!! Errors: 1x < Unexpected 'if' encountered 2x < Statement block must be terminated by '}' 1x < Ecpected a field name after '.' operator. How can these errors be present, when the original SWF works perfectly??! If I don't manage to solve this, I'll have to find out how to create an .php file the SWF tries to use which can select the proper resources (from a database I guess) to show them (using ?genre=###) Thanks!

• Is it possible to handle User Defined Exception using JAX WS Dispatch API ?

  - by snowflake

  Hello, I'm performing dynamic webservices call using following code snippet: JAXBContext jc = getJAXBContext(requestClass, responseClass, jaxbContextExtraClasses); Dispatch<Object> dispatch = service.createDispatch(portQName, jc, Service.Mode.PAYLOAD); Object requestValue = getRequestValue(requestClass, pOrderedParameters); JAXBElement<?> request = new JAXBElement(new QName(serviceQNameStr, pOperationName), requestValue.getClass(), null, requestValue); Object tmpResponse = dispatch.invoke(request); Invocation works perfectly, except if I add a user defined exception on the service (a basic UserException extends java.lang.Exception). First I get: javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). Expected elements are <{http://my.namespace/}myMethod,<{http://my.namespace/}myResponse Then I added the UserException_Exception JAX-WS generated type to my JAXB Context, and then get: Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions java.lang.StackTraceElement does not have a no-arg default constructor. this problem is related to the following location: at java.lang.StackTraceElement at public java.lang.StackTraceElement[] java.lang.Throwable.getStackTrace() at java.lang.Throwable at java.lang.Exception Only solution available I found are: dispatch directly a Soap message and handle Soap fault directly (this is the way Jboss JAX-WS implementation performs a standard JAX-WS call using services interfaces). This is not an available solution for me, I want to use a high level implementation (the more I get close to Soap message the less dynamic my code can be) usage of JAXBRIContext.ANNOTATION_READER, which is implementation specific and not an available solution for me, in order to annotate annotates java.lang.Exception as @XmlTransient The service with a user defined exception performs well using the JAX-WS generated standard client stubs and using a tool such Soap UI. Problem occurs in deserialization of the message when I have no user defined exception artifact in the JAXB context, and during invocation when I add those non JAXB compatible artifacts in the JAXB context. I'm usign Jboss WS webservice stack within Jboss 4.2.3.GA Any elegant solution to this problem is welcomed !

• Why do properties require explicit typing during compilation?

  - by ctpenrose

  Compilation using property syntax requires the type of the receiver to be known at compile time. I may not understand something, but this seems like a broken or incomplete compiler implementation considering that Objective-C is a dynamic language. The property "comment" is defined with: @property (nonatomic, retain) NSString *comment; and synthesized with: @synthesize comment; "document" is an instance of one of several classes which conform to: @protocol DocumentComment <NSObject> @property (nonatomic, retain) NSString *comment; @end and is simply declared as: id document; When using the following property syntax: stringObject = document.comment; the following error is generated by gcc: error: request for member 'comment' in something not a structure or union However, the following equivalent receiver-method syntax, compiles without warning or error and works fine, as expected, at run-time: stringObject = [document comment]; I don't understand why properties require the type of the receiver to be known at compile time. Is there something I am missing? I simply use the latter syntax to avoid the error in situations where the receiving object has a dynamic type. Properties seem half-baked.

• How to know when StatusBar size changed (iPhone)

  - by JOM

  I have UITabBarController with 2 tabs. One resizes just fine, when StatusBar size changes (emulator "Toggle In-Call Status Bar" menu item). The other one doesn't. The problematic tab item contains a static view, which dynamically loads one or another view depending on certain things. While getting this setup working I discovered that main tab view did NOT automagically send e.g. viewWillAppear and viewWillDisappear messages to my dynamic subviews. Apple docs explained this was because dynamically added views were not recognized by the system. @interface MyTabViewController : UIViewController { UIView *mainView; FirstViewController *aController; SecondViewController *bController; } ... if (index == 0) { self.aController = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil]; [self.mainView addSubview:aController.view]; [self.aController viewWillAppear:YES]; } How can I get StatusBar size changed event into my dynamic subviews? The "didChangeStatusBarFrame" doesn't work, as documented elsewhere.

• How do I compress a Json result from ASP.NET MVC with IIS 7.5

  - by Gareth Saul

  I'm having difficulty making IIS 7 correctly compress a Json result from ASP.NET MVC. I've enabled static and dynamic compression in IIS. I can verify with Fiddler that normal text/html and similar records are compressed. Viewing the request, the accept-encoding gzip header is present. The response has the mimetype "application/json", but is not compressed. I've identified that the issue appears to relate to the MimeType. When I include mimeType="*/*", I can see that the response is correctly gzipped. How can I get IIS to compress WITHOUT using a wildcard mimeType? I assume that this issue has something to do with the way that ASP.NET MVC generates content type headers. The CPU usage is well below the dynamic throttling threshold. When I examine the trace logs from IIS, I can see that it fails to compress due to not finding a matching mime type. <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" noCompressionForProxies="false"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" /> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/json" enabled="true" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/atom+xml" enabled="true" /> <add mimeType="application/xaml+xml" enabled="true" /> <add mimeType="application/json" enabled="true" /> </staticTypes> </httpCompression>

• How do people know so much about programming?

  - by Luciano

  I see people in this forums with a lot of points, so I assume they know about a lot of different programming stuff. When I was young I knew about basic (commodore) and the turbo pascal (pc). Then in college I learnt about C, memory management, x86 set, loop invariants, graphs, db query optimization, oop, functional, lambda calculus, prolog, concurrency, polymorphism, newton method, simplex, backtracking, dynamic programming, heuristics, np completeness, LR, LALR, neural networks, static & dynamic typing, turing, godel, and more in between. Then in industry I started with Java several years ago and learnt about it, and its variety of frameworks, and also design patterns, architecture patterns, web development, server development, mobile development, tdd, bdd, uml, use cases, bug trackers, process management, people management if you are a tech lead, profiling, security concerns, etc. I started to forget what I learnt in college... And then there is the stuff I don't know yet, like python, .net, perl, JVM stuff like groovy or scala.. Of course Google is a must for rapid documentation access to know if a problem has been solved already and how, and to keep informed about new stuff by blogs and places like this one. It's just too much or I just have a bad memory.. how do you guys manage it?

• NHibernate with nothing but stored procedures

  - by ChrisB2010

  I'd like to have NHibernate call a stored procedure when ISession.Get is called to fetch an entity by its key instead of using dynamic SQL. We have been using NHibernate and allowing it to generate our SQL for queries and inserts/updates/deletes, but now may have to deploy our application to an environment that requires us to use stored procedures for all database access. We can use sql-insert, sql-update, and sql-delete in our .hbm.xml mapping files for inserts/updates/deletes. Our hql and criteria queries will have to be replaced with stored procedure calls. However, I have not figured out how to force NHibernate to use a custom stored procedure to fetch an entity by its key. I still want to be able to call ISession.Get, as in: using (ISession session = MySessionFactory.OpenSession()) { return session.Get<Customer>(customerId); } and also lazy load objects, but I want NHibernate to call my "GetCustomerById" stored procedure instead of generating the dynamic SQL. Can this be done? Perhaps NHibernate is no longer a fit given this new environment we must support.

• one page has more than one url. search engines give penalty please help me out.

  - by Ali Demirtas

  Hi I am using prestashop as the cart for my website. I have a problem; the website used to be in dynamic urls. I enabled friendly url writing. The problem is that one page has more than one url. You can access a same page from the dynamic url and static url. In fact a single page has 9 different urls. This obviously creates problems for seo as search engiones penalize my website for this.

• Sorting, Filtering and Paging in ASP.NET MVC

  - by ali62b

  What is the best approach to implement these features and which part of project would involved? I see some example of JavaScript grids, but I'm talking about a general approach which best fits the MVC architecture. I've considered configuring routes and models to implement these features but I don't have a clear idea that if this is the right approach to implementing such features. On the one hand, I think if we put logic in routes (item/page/sort/), we would have benefits like bookmarking and avoiding JavaScript. On the other hand if we use JavaScript grids, we can have behavior like the old school grid views in ASP.NET web forms. I find that using HTML helpers may be useful for paging, but have no idea if they are good for sorting or not. I've looked at jQuery, tableSorter and quick search plug-ins, but they work just on the currently-fetched data and won't help in real sorting and filtering that may need to touch the database. I have some thoughts on using these tools side by side with AJAX to get something which works, but I have no idea if there are similar efforts done yet anywhere. Another approach I looked at was using Dynamic Data on web forms, but I didn't find any suggestions out there as to whether or not it is a good idea to integrate MVC and DD. I know implementing filtering and sorting for an individual case is simple (although it has some issues like using Dynamic LINQ, which is not yet a standard approach), but creating a sorting or filtering tool which works in all cases is the idea I'm looking for. (Maybe this is because I want have something in hand when web form developers are wondering why I'm writing same code each time I want to implement a sort scenario for different Entities).

• Ruby on Rails - Static page as start page

  - by meetraghu28

  Hello! I am developing an app in RoR which has static and dynamic parts. The static portion is placed in the public/ folder of the app. Now if i have an index.html in my public folder then i will not be able to use the routes configured in my routes.rb The default configurations like map.connect /:controller/:action will not be usable if i have an index.html. So i removed the index html. Now i have a static page startpage.html in my public/ folder which has to be the starting page of the app. And the i have links in it for other static/dynamic pages. The RoR app is hosted in apache and i tried to configure the Virtual Host configuration by adding the DirectoryIndex param so that when ever a request comes for the site it will direct it to the startpage.html but still it takes me to the default controller that i have specified in routes.rb with map.root I dont want to add a dummy controller and action and create a view which has the startpage and configure routes.rb to use it as the root. What i am looking to do here is Basically startpage.html should be my first page in the app served as a static page from the public/ folder. This will then have links to other pages and controllers/actions Here i am not able to apache to redirect to the html page instead of passing on the control to rails application. Directory listing is also enabled by using Options Indexes but still no change. Any pointers anyone?

• priority queue with limited space: looking for a good algorithm

  - by SigTerm

  This is not a homework. I'm using a small "priority queue" (implemented as array at the moment) for storing last N items with smallest value. This is a bit slow - O(N) item insertion time. Current implementation keeps track of largest item in array and discards any items that wouldn't fit into array, but I still would like to reduce number of operations further. looking for a priority queue algorithm that matches following requirements: queue can be implemented as array, which has fixed size and _cannot_ grow. Dynamic memory allocation during any queue operation is strictly forbidden. Anything that doesn't fit into array is discarded, but queue keeps all smallest elements ever encountered. O(log(N)) insertion time (i.e. adding element into queue should take up to O(log(N))). (optional) O(1) access for *largest* item in queue (queue stores *smallest* items, so the largest item will be discarded first and I'll need them to reduce number of operations) Easy to implement/understand. Ideally - something similar to binary search - once you understand it, you remember it forever. Elements need not to be sorted in any way. I just need to keep N smallest value ever encountered. When I'll need them, I'll access all of them at once. So technically it doesn't have to be a queue, I just need N last smallest values to be stored. I initially thought about using binary heaps (they can be easily implemented via arrays), but apparently they don't behave well when array can't grow anymore. Linked lists and arrays will require extra time for moving things around. stl priority queue grows and uses dynamic allocation (I may be wrong about it, though). So, any other ideas?

• How to improve Java performance on Informix for Windows

  - by Michal Niklas

  I have problem with performance of Java UDR functions on Informix on Windows. On this server I already have some functions in C and SPL. I chose one function to write it in those 3 languages and I measured performance of this function on test table. Function calculates some kind of checksum so it does not use any db libraries etc. only string and math operations. I observed performance on 30k records with SQL like: select function(txt) from _tmp_perf_test and I changed function to 'function_c, function_spl or function_java. My performance tests showed that C function is the fastest, SPL function is about 5 times slower, where Java is 100 (one hundred!) times slower than C. I checked it few times and 1:100 ratio didn't improve. I changed Java function to simply return length of the string but even this do not help so it looks, that there is general problem with Java function invocation, because there was no difference in time between Java function that calculate checksum and Java function that returns length of the string. I increased JVM_MAX_HEAP_SIZE to 128 and it not helped too. I use IBM Informix Dynamic Server Version 11.50.TC6DE. The same test on Linux server: IBM Informix Dynamic Server Version 11.50.FC6 show more "normal" results, i.e. Java is slower from C and SPL but only 2 to 5 times. What can I do to improve Java performance on Informix server on Windows?

• Server.Execute(path).. executed page returns the calling pages' url from request.url..

  - by ClarkeyBoy

  Hey, As explained in the title, I am having a problem with getting the URL of the page being executed from within a page. Basically I have a dynamic catalogue, where customers select products they are interested in. The manager of the company I am doing this for would like to be able to create an up to date offline catalogue at any given time, to send out to customers who dont have an internet connection. So far its going really well. I am using Server.Execute to get the content for each page, then putting it in static html pages and changing the dynamic links to static html links (ie changing all aspx links to htm). I am able to output all the pages for about us, contact us, home, and the entire catalogue. However, one of the stylesheets which is included in the page based on the URL (if the page is in the administration section then it is not included, otherwise it is) is not being included in the pages when it should be. I have tried outputting the URL but it just returns the URL of the calling page, not the page being called. Does anyone have any idea why this is happening? Any help would be greatly appreciated. Regards, Richard Clarke

• Hybrid EAV/CR model via WCF (and statically-typed language)?

  - by Pat

  Background I'm working on the architecture for a cloud-based LOB application, using Silverlight for the client, WCF, ASP.NET/C# for server and SQL Server for storage. The data model requires some flexibility per user (ability to add custom properties and define validation rules for them, for example), and a hybrid EAV/CR persistence model on the server side will suit nicely. Problem I need an efficient and maintainable technology and approach to handle the transformation from the persisted EAV model to/from WCF (and similarly allow the client to bind to the resulting data - DataGrid is a key UI element)? Admission: I don't yet know enough about WCF to understand if it supports ExpandoObject directly, but I suspect it will. Options I started off looking at WCF RIA services, but quickly discovered they're heavily dependent upon both static type data and compile-time code generation. Neither of these appeal. The options I'm considering include: Using WCF RIA services and pass the data over the network directly in EAV form (i.e. Dictionary), and handle the binding issue purely on the client side (like this) Using a dynamic language (probably IronPython) to handle both ends of the communication, with plumbing to generate the necessary CLR type data on the client to allow binding, and transform to/from EAV form on the server (spam preventer stopped me from posting a URL here, I'll try it in a comment). Dynamic LINQ (CreateClass() and friends), although I'm way out of my depth there and don't know what the limitations on that approach might be yet. I'm interested in comments on these approaches as well as alternative approaches that might solve the problem. Other Notes The Silverlight client will not be the only consumer of the service, making me slightly uncomfortable with option #1 above. While the data model is flexible, it's not expected to be modified heavily. For argument's sake, we could assume that we might have 25 distinct data models active at a given time, with something like 10-20 unique data fields/rules each. Modifications to the data model will happen infrequently (typically when a new user is initially configured).

• Extand legacy site with another server-side programming platform best practice

  - by Andrew Florko

  Company I work for have a site developed 6-8 years ago by a team that was enthusiastic enough to use their own private PHP-based CMS. I have to put dynamic data from one intranet company database on this site in one week: 2-3 pages. I contacted company site administrator and she showed me administrative part - CMS allows only to insert html blocks & manage site map (site is deployed on machine that is inside company & fully accessible & upgradable). I'm not a PHP-guy & I don't want to dive into legacy hardly-who-ever-heard-about CMS engine I also don't want to contact developers team, 'cos I'm not sure they are still present and capable enough to extend this old days site and it'll take too much time anyway. I am about to deploy helper asp.net site on iis with 2-3 pages required & refer helper site via iframe from present site. New pages will allow to download some dynamic content from present site also. Is it ok and what are the pitfalls with iframe approach?

• Super simple CSS tooltip in a table, why is it not displaying and can I make it work?

  - by Kyle Sevenoaks

  Hi, I have been trying to implement many different tooltips on this page for my client, he's adamant that we have a picture of the product show up when you hover over the product name in the order page. I decided to use the super simple CSS tooltip, it's very easy to implement and does exactly what we want. It works on a dynamic page, the others I tried didn't. I have made an example here: CSS tooltip in table example. This page used to be displayed using divs, I have since changed it to a table, as it's tabular data and easier to work with. It worked fine when it used divs, now it's in a table, it won't display the span on hover. My questions are: Why is it not working? How can I make it work? If not, does anyone know another super easy to implement tooltip that can work properly on a dynamic page? Here's the DIV tooltip for reference: DIV display tooltip. Edit: Just noticed it kinda half works in IE8. Thanks.

• Custom webserver caching

  - by Mark Kinsella

  I'm working with a custom webserver on an embedded system and having some problems correctly setting my HTTP Headers for caching. Our webserver is generating all dynamic content as XML and we're using semi-static XSL files to display it with some dynamic JSON requests thrown in for good measure along with semi-static images. I say "semi-static" because the problems occur when we need to do a firmware update which might change the XSL and image files. Here's what needs to be done: cache the XSL and image files and do not cache the XML and JSON responses. I have full control over the HTTP response and am currently: Using ETags with the XSL and image files, using the modified time and size to generate the ETag Setting Cache-Control: no-cache on the XML and JSON responses As I said, everything works dandy until a firmware update when the XSL and image files are sometimes cached. I've seen it work fine with the latest versions of Firefox and Safari but have had some problems with IE. I know one solution to this problem would be simply rename the XSL and image files after each version (eg. logo-v1.1.png, logo-v1.2.png) and set the Expires header to a date in the future but this would be difficult with the XSL files and I'd like to avoid this. Note: There is a clock on the unit but requires the user to set it and might not be 100% reliable which is what might be causing my caching issues when using ETags. What's the best practice that I should employ? I'd like to avoid as many webserver requests as possible but invalidating old XSL and image files after a software update is the #1 priority.

• Truncating long strings with CSS: feasible yet?

  - by Sam Stokes

  Is there any good way of truncating text with plain HTML and CSS, so that dynamic content can fit in a fixed-width-and-height layout? I've been truncating server-side by logical width (i.e. a blindly-guessed number of characters), but since a 'w' is wider than an 'i' this tends to be suboptimal, and also requires me to re-guess (and keep tweaking) the number of characters for every fixed width. Ideally the truncation would happen in the browser, which knows the physical width of the rendered text. I've found that IE has a text-overflow: ellipsis property that does exactly what I want, but I need this to be cross-browser. This property seems to be (somewhat?) standard but isn't supported by Firefox. I've found various workarounds based on overflow: hidden, but they either don't display an ellipsis (I want the user to know the content was truncated), or display it all the time (even if the content wasn't truncated). Does anyone have a good way of fitting dynamic text in a fixed layout, or is server-side truncation by logical width as good as I'm going to get for now?

• MySQL multidimensional arrays...

  - by jay

  What is the best way to store data that is dynamic in nature using MySQL? Let's say I have a table in which one item is "dynamic". For some entries I need to store one value, but for others it could be one hundred values. For example let's say I have the following simple table: CREATE TABLE manager ( name char(50), worker_1_name(50), worker_2_name(50), ... worker_N_name(50) ); Clearly, this is not an ideal way to set up a database. Because I have to accommodate the largest group that a manager could potentially have, I am wasting a lot of space in the database. What I would prefer is to have a table that I can use as a member of another table (like I would do in C++ through inheritance) that can be used by the "manager" table to handle the variable number of employees. It might look something like this. CREATE TABLE manager ( name char(50), underlings WORKERS ); CREATE TABLE WORKERS ( name char(50), ); I would like to be able to add a variable number of workers to each manager. Is this possible or am I constrained to enumerating all the possible number of employees even though I will use the full complement only rarely?

• How should child views of UIScrollView report their bounds for contentSize?

  - by Mike

  I'm looking more for advice on the correct design for a view. What I have is a UIScrollView that contains one or more custom Views I have created. My problem is, who reports to the scrollview what it's contentSize should be? I have the following: UIView +-UIScrollView +-CustomView 1 with dynamic height depending on data +-CustomView 2 with dynamic Height depending on data The UIViewController creates new instances of the custom views with data and then adds them as subviews to the UIScrollView. The problem I'm having is how to set the value of the scrollview's contentSize? Right now, I'm not doing that and the contents of the scrollview are clipped with no scrolling possible. Should the custom view call [parent setContentSize:] in its drawRect:? Should the UIViewController query the custom view after creation to get its bounds and then call setContentSize? Should I subclass the UIScrollView to override addSubView to query each subview's height? Is there something else I'm missing? I hope I explained that properly. I'm new to this and still getting a handle on things.

• How to debug/break in codedom compiled code

  - by Jason Coyne

  I have an application which loads up c# source files dynamically and runs them as plugins. When I am running the main application in debug mode, is it possible to debug into the dynamic assembly? Obviously setting breakpoints is problematic, since the source is not part of the original project, but should I be able to step into, or break on exceptions for the code? Is there a way to get codedom to generate PDBs for this or something? Here is the code I am using for dynamic compliation. CSharpCodeProvider codeProvider = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } }); //codeProvider. ICodeCompiler icc = codeProvider.CreateCompiler(); CompilerParameters parameters = new CompilerParameters(); parameters.GenerateExecutable = false; parameters.GenerateInMemory = true; parameters.CompilerOptions = string.Format("/lib:\"{0}\"", Application.StartupPath); parameters.ReferencedAssemblies.Add("System.dll"); parameters.ReferencedAssemblies.Add("System.Core.dll"); CompilerResults results = icc.CompileAssemblyFromSource(parameters, Source); DLL.CreateInstance(t.FullName, false, BindingFlags.Default, null, new object[] { engine }, null, null);

• Malware - Technical anlaysis

  - by nullptr

  Note: Please do not mod down or close. Im not a stupid PC user asking to fix my pc problem. I am intrigued and am having a deep technical look at whats going on. I have come across a Windows XP machine that is sending unwanted p2p traffic. I have done a 'netstat -b' command and explorer.exe is sending out the traffic. When I kill this process the traffic stops and obviously Windows Explorer dies. Here is the header of the stream from the Wireshark dump (x.x.x.x) is the machines IP. GNUTELLA CONNECT/0.6 Listen-IP: x.x.x.x:8059 Remote-IP: 76.164.224.103 User-Agent: LimeWire/5.3.6 X-Requeries: false X-Ultrapeer: True X-Degree: 32 X-Query-Routing: 0.1 X-Ultrapeer-Query-Routing: 0.1 X-Max-TTL: 3 X-Dynamic-Querying: 0.1 X-Locale-Pref: en GGEP: 0.5 Bye-Packet: 0.1 GNUTELLA/0.6 200 OK Pong-Caching: 0.1 X-Ultrapeer-Needed: false Accept-Encoding: deflate X-Requeries: false X-Locale-Pref: en X-Guess: 0.1 X-Max-TTL: 3 Vendor-Message: 0.2 X-Ultrapeer-Query-Routing: 0.1 X-Query-Routing: 0.1 Listen-IP: 76.164.224.103:15649 X-Ext-Probes: 0.1 Remote-IP: x.x.x.x GGEP: 0.5 X-Dynamic-Querying: 0.1 X-Degree: 32 User-Agent: LimeWire/4.18.7 X-Ultrapeer: True X-Try-Ultrapeers: 121.54.32.36:3279,173.19.233.80:3714,65.182.97.15:5807,115.147.231.81:9751,72.134.30.181:15810,71.59.97.180:24295,74.76.84.250:25497,96.234.62.221:32344,69.44.246.38:42254,98.199.75.23:51230 GNUTELLA/0.6 200 OK So it seems that the malware has hooked into explorer.exe and hidden its self quite well as a Norton Scan doesn't pick anything up. I have looked in Windows firewall and it shouldn't be letting this traffic through. I have had a look into the messages explorer.exe is sending in Spy++ and the only related ones I can see are socket connections etc... My question is what can I do to look into this deeper? What does malware achieve by sending p2p traffic? I know to fix the problem the easiest way is to reinstall Windows but I want to get to the bottom of it first, just out of interest.
