• Monitoring Windows Azure Service Bus Endpoint with BizTalk 360?

  - by Michael Stephenson

  I'm currently working with a customer who is undergoing an initiative to expose some of their line of business applications to external partners and SAAS applications and as part of this we have been looking at using the Windows Azure Service Bus. For the first part of the project we were focused on some synchronous request response scenarios where an external application would use the Service Bus relay functionality to get data from some internal applications. When we were looking at the operational monitoring side of the solution it was obvious that although most of the normal server monitoring capabilities would be required for the on premise components we would have to look at new approaches to validate that the operation of the service from outside of the organization was working as expected. A number of months ago one of my colleagues Elton Stoneman wrote about an approach I have introduced with a number of clients in the past where we implement a diagnostics service in each service component we build. This service would allow us to make a call which would flex some of the working parts of the system to prove it was working within any SLA. This approach is discussed on the following article: http://geekswithblogs.net/EltonStoneman/archive/2011/12/12/the-value-of-a-diagnostics-service.aspx In our solution we wanted to take the same approach but we had to consider that the service clients were external to the service. We also had to consider that by going through Windows Azure Service Bus it's not that easy to make most of your standard monitoring solutions just give you an easy way to do this. In a previous article I have described how you can use BizTalk 360 to monitor things using a custom extension to the Web Endpoint Manager and I felt that we could use this approach to provide an excellent way to monitor our service bus endpoint. The previous article is available on the following link: http://geekswithblogs.net/michaelstephenson/archive/2012/09/12/150696.aspx   The Monitoring Solution BizTalk 360 currently has an easy way to hook up the endpoint manager to a url which it will then call and if a successful response is returned it then considers the endpoint to be in a healthy state. We would take advantage of this by creating an ASP.net web page which would be called by BizTalk 360 and behind this page we would implement the functionality to call the diagnostics service on our Service Bus endpoint. The ASP.net page could include logic to work out how to handle the response from the diagnostics service. For example if the overall result of the diagnostics service was successful but the call to the diagnostics service was longer than a certain amount of time then we could return an error and indicate the service is taking too long. The following diagram illustrates the monitoring pattern.   The diagnostics service which is hosted in the line of business application allows us to ping a simple message through the Azure Service Bus relay to the WCF services in the LOB application and we they get a response back indicating that the service is working fine. To implement this I used the exact same approach I described in my previous post to create a custom web page which calls the diagnostics service and then it would return an HTTP response code which would depend on the error condition returned or a 200 if it was successful. One of the limitations of this approach is that the competing consumer pattern for listening to messages from service bus means that you cannot guarantee which server would process your diagnostics check message but with BizTalk 360 you could simply add multiple endpoint checks so that it could access the individual on-premise web servers directly to ensure that each server is working fine and then check that messages can also be processed through the cloud. Conclusion It took me about 15 minutes to get a proof of concept of this up and running which was able to monitor our web services which had been exposed via Windows Azure Service Bus. I was then able to inherit all of the monitoring benefits of BizTalk 360 to provide an enterprise class monitoring solution for our cloud enabled API.

• How to import this data set into excel? (column headings on each row delimited by a colon)

  - by Anonymous

  I'm trying to import the following data set into Excel. I've had no luck with the text import wizard. I'd like Excel to make id, name, street, etc the column names and insert each record onto a new row. , id: sdfg:435-345, name: Some Name, type: , street: Address Line 1, Some Place, postalcode: DN2 5FF, city: Cityhere, telephoneNumber: 01234 567890, mobileNumber: 01234 567890, faxNumber: /, url: http://www.website.co.uk, email: [email protected], remark: , geocode: 526.2456;-0.8520, category: some, more, info , id: sdfg:435-345f, name: Some Name, type: , street: Address Line 1, Some Place, postalcode: DN2 5FF, city: Cityhere, telephoneNumber: 01234 567890, mobileNumber: 01234 567890, faxNumber: /, url: http://www.website.co.uk, email: [email protected], remark: , geocode: 526.2456;-0.8520, category: some, more, info Is there any easy way to do this with Excel? I'm struggling to think of a way to convert this to a conventional CSV easily. As far as I can think, I'd have to remove the labels from each line, enclose each line in quotes, then delimit them with commas. Obviously that's made a little more difficult to script though seeing as some fields (address, for instance) contain comma-delimited data. I'm not good with regex at all. What's the best way to tackle this?

• Big and reaaaally strange problem with a web server (host InMotion Hosting)

  - by altar

  Hi. I have a terrible problem that I have tried to solve since three days ago: I browse my own web site and after a while I cannot access the web site. AT ALL! I can only see a 501 error message: "Method Not Implemented. GET to / not supported. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request." Once I get that error the site is totally and permanently inaccessible in that browser!! Reboot, browser restarts, clear cache, clear all history and cookies, etc., are not working. I have reproduced it in 4 different computers. Three computers are in one city, the 4th is in another city. Two different ISP's also. One computer is Linux, the others are on Windows (XP and 2000). Browsers are FF 3 to FF3.5 and IE 8. The error is ALMOST reproducible on demand (for me at least). It appears when I browse the forum under certain circumstances. I don't know which are these circumstances, but if I browse it long enough (10 sec to 5 minutes) it eventually appears. Just to make it clear, once the error appears (while browsing the forum) then the whole web site become inaccessible, not only the forum! My host is not willing to help because they say they cannot reproduce the error. I sent screenoshots but they don't care. NEWS Reseting browser's settings from the 'Tools-Clear private data' din't worked. However! When I have cleared the same settings (more exaclty) cookies from the special menu that appears when you right click website's icon, it worked. So it was something related to a cookie BUT it manifests in all browsers (FF, IE, Opera). So it cannot be a browser related problem.

• Reading input from a text file, omits the first and adds a nonsense value to the end?

  - by Greenhouse Gases

  Hi there When I input locations from a txt file I am getting a peculiar error where it seems to miss off the first entry, yet add a garbage entry to the end of the link list (it is designed to take the name, latitude and longitude for each location you will notice). I imagine this to be an issue with where it starts collecting the inputs and where it stops but I cant find the error!! It reads the first line correctly but then skips to the next before adding it because during testing for the bug it had no record of the first location Lisbon though whilst stepping into the method call it was reading it. Very bizarre but hopefully someone knows the issue. Here is firstly my header file: #include <string> struct locationNode { char nodeCityName [35]; double nodeLati; double nodeLongi; locationNode* Next; void CorrectCase() // Correct upper and lower case letters of input { int MAX_SIZE = 35; int firstLetVal = this->nodeCityName[0], letVal; int n = 1; // variable for name index from second letter onwards if((this->nodeCityName[0] >90) && (this->nodeCityName[0] < 123)) // First letter is lower case { firstLetVal = firstLetVal - 32; // Capitalise first letter this->nodeCityName[0] = firstLetVal; } while(n <= MAX_SIZE - 1) { if((this->nodeCityName[n] >= 65) && (this->nodeCityName[n] <= 90)) { letVal = this->nodeCityName[n] + 32; this->nodeCityName[n] = letVal; } n++; } //cityNameInput = this->nodeCityName; } }; class Locations { private: int size; public: Locations(){ }; // constructor for the class locationNode* Head; //int Add(locationNode* Item); }; And here is the file containing main: // U08221.cpp : main project file. #include "stdafx.h" #include "Locations.h" #include <iostream> #include <string> #include <fstream> using namespace std; int n = 0,x, locationCount = 0, MAX_SIZE = 35; string cityNameInput; char targetCity[35]; bool acceptedInput = false, userInputReq = true, match = false, nodeExists = false;// note: addLocation(), set to true to enable user input as opposed to txt file locationNode *start_ptr = NULL; // pointer to first entry in the list locationNode *temp, *temp2; // Part is a pointer to a new locationNode we can assign changing value followed by a call to Add locationNode *seek, *bridge; void setElementsNull(char cityParam[]) { int y=0, count =0; while(cityParam[y] != NULL) { y++; } while(y < MAX_SIZE) { cityParam[y] = NULL; y++; } } void addLocation() { temp = new locationNode; // declare the space for a pointer item and assign a temporary pointer to it if(!userInputReq) // bool that determines whether user input is required in adding the node to the list { cout << endl << "Enter the name of the location: "; cin >> temp->nodeCityName; temp->CorrectCase(); setElementsNull(temp->nodeCityName); cout << endl << "Please enter the latitude value for this location: "; cin >> temp->nodeLati; cout << endl << "Please enter the longitude value for this location: "; cin >> temp->nodeLongi; cout << endl; } temp->Next = NULL; //set to NULL as when one is added it is currently the last in the list and so can not point to the next if(start_ptr == NULL){ // if list is currently empty, start_ptr will point to this node start_ptr = temp; } else { temp2 = start_ptr; // We know this is not NULL - list not empty! while (temp2->Next != NULL) { temp2 = temp2->Next; // Move to next link in chain until reach end of list } temp2->Next = temp; } ++locationCount; // increment counter for number of records in list if(!userInputReq){ cout << "Location sucessfully added to the database!

• HTML5 Form: Page Is Reloading Instantly After Restyling (And It Shouldn't Be)

  - by user3689753

  I have a form. I have made it so that if your name is not put in, a red border is put on the name field. That works, BUT...it's for a split second, and then the page reloads. I want the red border to appear, and then stay there. For some reason it's for a split second. Can someone help me make it so the page doesn't reload after displaying the red border? Here's the script. window.onload = function() { document.getElementById("Hogwarts").onsubmit = function () { window.alert("Form submitted. Owl being sent..."); var fname = document.getElementById("fName"); if(!fName.value.match("^[A-Z][A-Za-z]+( [A-Z][A-Za-z]*)*$")) { window.alert("You must enter your name."); addClass(fName, "errorDisp"); document.getElementById("fName").focus(); } else return true; } } function addClass(element, classToAdd) { var currentClassValue = element.className; if (currentClassValue.indexOf(classToAdd) == -1) { if ((currentClassValue == null) || (currentClassValue === "")) { element.className = classToAdd;

• count specific values in a multidimensional array

  - by user1680701

  I have an odd set of arrays that I need to count how many times specific values show in the results. Currently I have this bit of code. $nested_arrays = shopp_orders( '2011-11-30 00:00:00', '2012-11-30 12:59:59', false, '', 2 ); print_r($nested_arrays); This code pulls multiple arrays (serialized

I need to count how many times each state, each city, shipmethod, etc occur in the array. I tried the following but it only counted the 2 large arrays. function count_nested_array_keys(array &$a, array &$res=array()) { $i = 0; foreach ($a as $key=>$value) { if (is_array($value)) { $i += count_nested_array_keys($value, &$res); } else { if(!isset($res[$key])) $res[$key] = 0; $res[$key]++; $i++; } } return $i; } $total_item_count = count_nested_array_keys($nested_arrays, $count_per_key); echo "count per key: ", print_r($count_per_key), "\n"; If someone could show me how to count how many times each state value occurs, example, VA = 2 NC = 1 I can take it from there. Thank You.

• How can I use external expressions in Linq with EF4 (and LINQKit)?

  - by neo

  I want to separate out often used expressions in linq queries. I'm using Entity Framework 4 and also LINQKit but I still don't know how I should do it the right way. Let me give you an example: Article article = dataContainer.Articles.FirstOrDefault(a => a.Id == id); IEnumerable<Comment> comments = (from c in container.Comments where CommentExpressions.IsApproved.Invoke(c) select c); public static class CommentExpressions { public static Expression<Func<Module, bool>> IsApproved { get { return m => m.IsApproved; } } } Of course the IsApproved expression would be something much more complicated. The problem is that the Invoke() won't work because I didn't call .asExpandable() from LINQKit on container.Comments but I can't call it because it's just an ICollection instead of an ObjectSet. So my question is: Do I always have to go through the data context when I want to include external expressions or can I somehow use it on the object I fetched (Article)? Any ideas or best practices? Thanks very much! neo

• thesis in LaTeX without memoir

  - by yCalleecharan

  Hi, I'm preparing a thesis report in LaTeX. I don't want to use the memoir class as I would like total control. I have two questions: My thesis consists of an introduction and then a series of articles pasted one after the other. Thus each article has its own abstract, introduction, etc... and a bibliography at its end. I understand that perhaps a package like multibib can help when we have multiple bibliographies. The idea that I came with is to write each article separately and then use pdfpages to combine the final document. Long time ago dvi files concatenation was popular but with graphics I think that pdfpages is better. I saw that another package exists, named combine which can help with what I am doing. I'm still exploring my options. Any suggestions? If I decide to use a book class instead to make my thesis resemble more into a book-like format which is better, then using the book class format gives me section headings like 0.1 Introduction with the leading 0. This 0 doesn't show in the article class format. How to change this default book class numbering format so that I'll have e.g. 1. Introduction? Thanks a lot...

• MySQL use certain columns, based on other columns

  - by Rabbott

  I have this query: SELECT COUNT(articles.id) AS count FROM articles, xml_documents, streams WHERE articles.xml_document_id = xml_documents.id AND xml_documents.stream_id = streams.id AND articles.published_at BETWEEN '2010-01-01' AND '2010-04-01' AND streams.brand_id = 7 Which just uses the default equajoin by specifying three tables in csv format in the FROM clause.. What I need to do is group this by a value found within articles.source (raw xml).. so it could turn into this: SELECT COUNT(articles.id) AS count, ExtractValue(articles.source, "/article/media_type") AS media_type FROM articles, xml_documents, streams WHERE articles.xml_document_id = xml_documents.id AND xml_documents.stream_id = streams.id AND articles.published_at BETWEEN '2010-01-01' AND '2010-04-01' AND streams.brand_id = 7 GROUP BY media_type which works fine, the problem is, I'm using rails, and using STI for the xml_documents table. The articles.source that is provided to the ExtractValue method will be of a couple different formats.. So what I need to be able to do is use "/article/media_type" IF xml_documents.type = 'source one' and use "/article/source" if xml_documents.type = 'source two' This is just because the two document types format their XML differently, but I don't want to have to run multiple queries to retrieve this information.. It would be nice if one could use a ternary operator, but i don't think this is possible.. EDIT At this Point I am looking at making a temp table, or simply using UNION to place multiple result sets together..

• Creating custom IP-STS for sharepoint foundation 2010 without ADFS

  - by user252229

  I plan to create very simple custom IP-STS for SharePoint foundation 2010 without ADFS server so anyone can integrate Windows Live ID to SharePoint foundation 2010 simply without ADFS, I can't use ADFS server because it could not install on Windows Web Server 2008 (Web Edition), also I found many article use LDAP provider but it does not exists in SharePoint Foundation too (it requires Sharepoint Server Edition). After too much searching I just found the following article and find all technique except one problem. 1) Creating Custom Claim Provider: blogs.technet.com/b/speschka/archive/2010/03/13/writing-a-custom-claims-provider-for-sharepoint-2010-part-1.aspx 2) Creating Custom STS Provider: http://blogs.msdn.com/b/chunliu/archive/2010/04/02/how-to-make-use-of-a-custom-ip-sts-with-sharepoint-2010-part-1.aspx Only one step remains: I got following error after enter username in STS site and redirect to localhost/_trust/default.aspx , ( I leave EncryptingCertificateName empty). Operation is not valid due to the current state of the object I expect to get access denied error instead of that error. 1.Is it possible anyway? 2.Can anyone help me where can I find working article to create custom IP-STS without ADFS server Any idea will help me Thanks

• HTML5 for IE6.0

  Hello! Do you know any method to optimize this HTML Code to IE6 or 7 (or 8) without adding any HTML elements, or the IE is skipping all the HTML5 elements? If i just want to format elements with CSS, - i dont want to use other features - is the document.createElement("nav") DOM element create enough to scam IE and make a plain HTML document? <!DOCTYPE HTML> <head> <meta charset="UTF-8"> <title>title</title> <link type="text/css" rel="stylesheet" href="reset.css"> <link type="text/css" rel="stylesheet" href="style.css"> </head> <body> <header>code of header</header> <nav> code of nav </nav> <section> code of gallery </section> <article> code of article </article> <footer>code of footer</footer> </body> </html> Thank you.

• Pagination in Joomla!

  Hi every one. I'm a bit new to Joomla! and I'm building my new web site using Joomla! 1.5.8 with a template bought from RocketTheme. The long article in question is a gallery of photos, and I wanted to create a horizontal pagination nav-bar in the footer of the gallery, I just clicked pagebreak where I wanted to paginate in my article in the WYSIWYG editor and thought that it's actually all I have to do. What I got was ugly; a vertically directed navigation bar placed in the top right side of my gallery with the links to each part of the article, the all without the minimum styling. And as I see it's a table! Why not outputting a list instead of a table! (Well this is not actually my concern right now). I can understand CSS and html, but I'm not really a PHP guy, so I don't understand how to use pagination.php or pagenavigation.php! Do I have to customize one of them to have my nav-bar? What I have to do to get that horizontal nav-bar? Really thanks in advance. Wassim

• Does the COM server have to call SysFreeString() for an [out] parameter?

  - by sharptooth

  We have the following interface: [object, uuid("uuidhere"), dual ] interface IInterface : IDispatch { [id(1), propget] HRESULT CoolProperty( [out, retval] BSTR* result ); } Now there's a minor problem. On one hand the parameter is "out" and so any value can be passed as input, the parameter will become valid only upon the successful return. On the other hand, there's this MSDN article which is linked to from many pages that basically says (the last paragraph) that if any function is passed a BSTR* it must free the string before assigning a new string. That's horrifying. If that article is right it means that all the callers must surely pass valid BSTRs (maybe null BSTRs), otherwise BSTR passed can be leaked. If the caller passed a random value and the callee tries to call SysFreeString() it runs into undefined behavior, so the convention is critical. Then what's the point in the [out] attribute? What will be the difference between the [in, out] and [out] in this situation? Is that article right? Do I need to free the passed BSTR [out] parameter before assigning a new one?

• Is there an easier way with jQuery accordions?

  - by Josh

  I've been struggling with a feature I've been trying to create for sometime. The idea here is that the user sees the little thumbnail + headline, as well as the Posted By information. They can then click on the headline to expand to the article or click on the "Comments" link to expand directly to the comments made on the article. Or, if they want they can view comments by clicking on the headline(to expand to the article), then click on View Comments (to expand to the comments). In the end, a modular yet flexible and functional open/close system to view latest news. Here is what I've been working on: (I put all my code in one place so its easier on whomever may look at this to view) http://notedls.com/pointtest.html This is what I'm shooting for, but it's far from what I want ;( It's using the jQuery 1.6 plugin, which 1.8 is out but I'm far from being a master or expert at this and I don't think I could build from the ground up. I've already edited this plugin to get it to work like this, but as you can see, the AUTHOR and Comments start making shit hit the fan ;; It's because the code is calling the "A TAG" for the header; which is the headline. Does anyone know any easier way to achieve what I'm envisioning or possible a way to fix this current code? I'm pretty desperate at this point ;;

• sql server 2005 stored procedure unexpected behaviour

  - by user283405

  i have written a simple stored procedure (run as job) that checks user subscribe keyword alerts. when article posted the stored procedure sends email to those users if the subscribed keyword matched with article title. One section of my stored procedure is: OPEN @getInputBuffer FETCH NEXT FROM @getInputBuffer INTO @String WHILE @@FETCH_STATUS = 0 BEGIN --PRINT @String INSERT INTO #Temp(ArticleID,UserID) SELECT A.ID,@UserID FROM CONTAINSTABLE(Question,(Text),@String) QQ JOIN Article A WITH (NOLOCK) ON A.ID = QQ.[Key] WHERE A.ID > @ArticleID FETCH NEXT FROM @getInputBuffer INTO @String END CLOSE @getInputBuffer DEALLOCATE @getInputBuffer This job run every 5 minute and it checks last 50 articles. It was working fine for last 3 months but a week before it behaved unexpectedly. The problem is that it sends irrelevant results. The @String contains user alert keyword and it matches to the latest articles using Full text search. The normal execution time is 3 minutes but its execution time is 3 days (in problem). Now the current status is its working fine but we are unable to find any reason why it sent irrelevant results. Note: I am already removing noise words from user alert keyword. I am using SQL Server 2005 Enterprise Edition.

Do you know any method to optimize this HTML Code to IE6 or 7 (or 8) without adding any HTML elements, or the IE is skipping all the HTML5 elements? <!DOCTYPE HTML> <head> <meta charset="UTF-8"> <title>title</title> <link type="text/css" rel="stylesheet" href="reset.css"> <link type="text/css" rel="stylesheet" href="style.css"> </head> <body> <header>code of header</header> <nav> code of nav </nav> <section> code of gallery </section> <article> code of article </article> <footer>code of footer</footer> </body> </html> Thank you.

• MEF and ASP.NET MVC

  - by denis_n

  I want to use MEF with asp.net mvc. I wrote following controller factory: public class MefControllerFactory : DefaultControllerFactory { private CompositionContainer _Container; public MefControllerFactory(Assembly assembly) { _Container = new CompositionContainer(new AssemblyCatalog(assembly)); } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { if (controllerType != null) { var controllers = _Container.GetExports<IController>(); var controllerExport = controllers.Where(x => x.Value.GetType() == controllerType).FirstOrDefault(); if (controllerExport == null) { return base.GetControllerInstance(requestContext, controllerType); } return controllerExport.Value; } else { throw new HttpException((Int32)HttpStatusCode.NotFound, String.Format( "The controller for path '{0}' could not be found or it does not implement IController.", requestContext.HttpContext.Request.Path ) ); } } } In Global.asax.cs I'm setting my controller factory: protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); ControllerBuilder.Current.SetControllerFactory(new MefControllerFactory.MefControllerFactory(Assembly.GetExecutingAssembly())); } I have an area: [Export(typeof(IController))] [PartCreationPolicy(CreationPolicy.NonShared)] public class HomeController : Controller { private readonly IArticleService _articleService; [ImportingConstructor] public HomeController(IArticleService articleService) { _articleService = articleService; } // // GET: /Articles/Home/ public ActionResult Index() { Article article = _articleService.GetById(55); return View(article); } } IArticleService is an interface. There is a class which implements IArticleService and Exports it. It works. Is this everything what I need for working with MEF? How can I skip setting PartCreationPolicy and ImportingConstructor for controller? I want to set my dependencies using constructor. When PartCreationPolicy is missing, I get following exception: A single instance of controller 'MvcApplication4.Areas.Articles.Controllers.HomeController' cannot be used to handle multiple requests. If a custom controller factory is in use, make sure that it creates a new instance of the controller for each request.

• Avoid loading unnecessary data from db into objects (web pages)

  - by GmGr

  Really newbie question coming up. Is there a standard (or good) way to deal with not needing all of the information that a database table contains loaded into every associated object. I'm thinking in the context of web pages where you're only going to use the objects to build a single page rather than an application with longer lived objects. For example, lets say you have an Article table containing id, title, author, date, summary and fullContents fields. You don't need the fullContents to be loaded into the associated objects if you're just showing a page containing a list of articles with their summaries. On the other hand if you're displaying a specific article you might want every field loaded for that one article and maybe just the titles for the other articles (e.g. for display in a recent articles sidebar). Some techniques I can think of: Don't worry about it, just load everything from the database every time. Have several different, possibly inherited, classes for each table and create the appropriate one for the situation (e.g. SummaryArticle, FullArticle). Use one class but set unused properties to null at creation if that field is not needed and be careful. Give the objects access to the database so they can load some fields on demand. Something else? All of the above seem to have fairly major disadvantages. I'm fairly new to programming, very new to OOP and totally new to databases so I might be completely missing the obvious answer here. :)

• Prevent comment form re-submission

  - by Rob

  I'm got a comment form for an article and i'd to prevent re-submission. I notice that Worpdress handles this very well (going back doesn't cause the browser to request a form re-submission), but I can't figure out how they do it, even though our methods are very similar. My Script User visits mydomain.com/article/1/article_title.html Fills in a form which posts to mydomain.com/addnewcomment/1.html I then do a 302 redirect back to mydomain.com/article/1/article_title.html Now if I press back from this position it doesn't request a redirect. However, if I go to another page e.g. mydomain.com/tag/1/my_tag.html and press back it does resubmit the form. Obviously I want to prevent this. What Wordpress does User visits mydomain.com/?p=1 Fills in a form which posts to mydomain.com/wp-comments-post.php This then does a 302 redirect back to mydomain.com/?p=1 Pressing back or visiting another page and pressing back doesn't cause a re-submission. I've had a look through the WP code but I can't see how they manage this. Obviously it's something i'd like to achieve. Does anyone have any thoughts on where I may be going wrong? (I'm only using Wordpress as an example to prove that it's possible, obviously i'm not trying to exactly duplicate WP, that would be pointless)

• Differences between Assembly Code output of the same program

  - by ultrajohn

  I have been trying to replicate the buffer overflow example3 from this article aleph one I'm doing this as a practice for a project in a computer security course i'm taking so please, I badly need your help. I've been the following the example, performing the tasks as I go along. My problem is the assembly code dumped by gdb in my computer (i'm doing this on a debian linux image running on VM Ware) is different from that of the example in the article. There are some constructs which I find confusing. Here is the one from my computer: here is the one from the article... Dump of assembler code for function main: 0x8000490 <main>: pushl %ebp 0x8000491 <main+1>: movl %esp,%ebp 0x8000493 <main+3>: subl $0x4,%esp 0x8000496 <main+6>: movl $0x0,0xfffffffc(%ebp) 0x800049d <main+13>: pushl $0x3 0x800049f <main+15>: pushl $0x2 0x80004a1 <main+17>: pushl $0x1 0x80004a3 <main+19>: call 0x8000470 <function> 0x80004a8 <main+24>: addl $0xc,%esp 0x80004ab <main+27>: movl $0x1,0xfffffffc(%ebp) 0x80004b2 <main+34>: movl 0xfffffffc(%ebp),%eax 0x80004b5 <main+37>: pushl %eax 0x80004b6 <main+38>: pushl $0x80004f8 0x80004bb <main+43>: call 0x8000378 <printf> 0x80004c0 <main+48>: addl $0x8,%esp 0x80004c3 <main+51>: movl %ebp,%esp 0x80004c5 <main+53>: popl %ebp 0x80004c6 <main+54>: ret 0x80004c7 <main+55>: nop As you can see, there are differences between the two. I'm confuse and I can't understand totally the assembly code from my computer. I would like to know the differences between the two. How is pushl different from push, mov vs movl , and so on... what does the expression 0xhexavalue(%register) means? I am sorry If I'm asking a lot, But I badly need your help. Thanks for the help really...

• Content Management Systems for Adaptive Content [closed]

  - by andrewap

  Content management systems (CMS) allow us to easily maintain blogs, news sites, general websites, and so on. Many of them are designed to manage pages of content, and provide tools to organize and customize how that content is displayed on the web. However, as explained by Mark Boulton in his Adaptive Content Management article, and by Karen McGrane in her talk on Adapting Ourselves to Adaptive Content, we are increasingly delivering content not just to the web, but also to other platforms and channels. We need tools to manage pieces of content with meaningful metadata attached. Create once, publish everywhere. The main idea is to store content cleanly, without intertwining it with presentation markup specific to the web. Because pieces of content is compartmentalized semantically, it can easily adapt to fit in different platforms and channels. Hence, it's called adaptive content. Let's look at a quick example to compare: Say I manage news articles and events. To create a news article, I would tell the CMS the type of content I'm creating, and be asked to fill in a form with individual fields tailored to news articles (e.g. headline, subtitle, full text, short snippet, and images). — i.e. pieces of content With a traditional web publishing tool, I would probably have had to create a new page under News, and then type in and format the news article in a blank WYSIWYG text editor. — i.e. pages of content As you can see, the first design allows me to individually specify content in its smallest semantic unit. When I want to display or consume it, the system can easily provide the pieces I need. So here's my question: Is there a CMS that is designed specifically with adaptive content in mind, and that is decoupled with the presentation layer? Note: This is not a discussion about the best CMS, or which CMS I should use. I am asking whether a very specific type of tool — CMS designed for adaptive content — exists for developers to use.

• Adding an ASP.NET Web User Control to a Control Dynamically

  - by RandomBen

  I have a simple ASP.NET Web User Control. It looks like this: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="NewsArticle.ascx.cs" Inherits="Website.Controls.NewsArticle" %> <div> <asp:Literal ID="ltlBody" runat="server" /> </div> My code behind looks like this: namespace Website.Controls { public partial class NewsArticle : System.Web.UI.UserControl { public String bodyText { //get { return ltlBody.Text; } set { ltlBody.Text = value; } } } } On a .aspx page I have <asp:Panel ID="pNews" runat="server" /> In the code behind I have: foreach (vwNews news in newsQuery) { NewsArticle article = new NewsArticle(); aticle.bodyText = news.Body; pNews.Controls.Add(article); } Every time I run this code the newsQuery is populated correctly and I get to the line aticle.bodyText = news.Body; and then I received the error article.bodyText threw an exception of type 'System.NullReferenceException' I am not sure what is causing this error message or how to fix it. I would think that there should not be an issue. I tried creating a constructor for my Web User Control so that it would give default values to my properties but that didn't work. Any idea how to make this work? It doesn't seem like it should be that

• Does unboxing just return a pointer to the value within the boxed object on the heap?

  - by Charles

  I this MSDN Magazine article, the author states (emphasis mine): Note that boxing always creates a new object and copies the unboxed value's bits to the object. On the other hand, unboxing simply returns a pointer to the data within a boxed object: no memory copy occurs. However, it is commonly the case that your code will cause the data pointed to by the unboxed reference to be copied anyway. I'm confused by the sentence I've bolded and the sentence that follows it. From everything else I've read, including this MSDN page, I've never before heard that unboxing just returns a pointer to the value on the heap. I was under the impression that unboxing would result in you having a variable containing a copy of the value on the stack, just as you began with. After all, if my variable contains "a pointer to the value on the heap", then I haven't got a value type, I've got a pointer. Can someone explain what this means? Was the author on crack? (There is at least one other glaring error in the article). And if this is true, what are the cases where "your code will cause the data pointed to by the unboxed reference to be copied anyway"? I just noticed that the article is nearly 10 years old, so maybe this is something that changed very early on in the life of .Net.
