• Search and highlight html - ignoring and maintaining tags

  - by Sleepwalker

  I am looking for a good way to highlight key words in a block of html with stripping the html tags. I can regex to search for key words within html tags, but I haven't found a great way to search across tags. For example, if the key word phrase is "not bound" I want to be able to make this <p>I am not<strong>bound to please thee</strong> with my answers.</p> become wrapped in highlight tags, without breaking the "strong" tag (and making the html invalid) and become: <p>I am <span class="highlight">not</span><strong><span class="highlight">bound</span> to please thee</strong> with my answers.</p> The main issue is maintaining the html as it is AND wrapping blocks of text with highlight tags. I need to maintain the original html. Otherwise I would strip the tags. The best solution to this that I can think of right now would entail making a copy of the html and placing counter tokens where each space occurs, then stripping all tags and search for matching phrases, then looking back to the original and the tokenized strings and figuring out where to start building the highlight tags, then start walking forward, starting and ending highlight spans as needed from the beginning of the match until the end. This seems like overkill. I would like to something more elegant if possible. The solution would be written in C# or perhaps javascript, depending.

• Play framework does not return page and static content

  - by Anton

  I'm using play framework in production for one of my web projects. From time to time Play does not render main page or does not return some of the static content files. I have attached few screenshots below. First screenshot displays firebug console, loading of the site is stucked at the beginning, when serving home page. Second screenshot display fiddler console, when 2 static resources are not loading. This issue is hard to reproduce, it happens 1 of 15 time, I have to delete cache data and reload page. (pressing CRTL-F5 in FF). Issue can be reproduced in most of the browsers. Initially, I was thinging that there is something wrong with hosting provider. But I have changed hosting provided and issue has not gone. Version of the play is 1.2.2. Play is running as standalone server. Not sure, but probably deploying Play to Jetty/Tomcat/Resin would help. Also I'm thinging about rewriting application to another stack (well-known for me - j2ee, spring, whatever) I have no idea how to debug and resolve this issue. Any clue ? Has anyone faced same issue with Play before ?

• C#: Take Out Image Portion of JPEG to Backup Metadata?

  - by Carlo Mendoza

  This will be a little backwards from the typical approach. I've used ExifTool for metadata manipulation before, but I really want to keep the best metadata backup I can before I make anything permanent. What I want to do is remove the compressed image portion of a JPEG file to leave everything else intact. That's backing up EXIF, Makernotes, IPTC, XMP, etc whether at the beginning or end of the file. What I've tried so far is to strip all metadata from a copy of the original JPEG, and use it as a basis of what bytes will be taken out of the original. After looking at the raw data, it doesn't seem like the stripped copy is contiguous in the original copy. There may be some header information still remaining in the stripped version. I don't really know. Not a good way to do it, I suppose. Are there any markers that will absolutely tell me where the compressed JPEG image data starts and ends? I understand that JPEG files have 0xFFD8 and 0xFFD9 to mark the start and end of the image, but have come to find out that metadata is actually between those markers. I'm using C#. Thank you.

• Problem with document.location.href

  - by novellino

  Hello, I am new to Javascript and Web development and I have a question regarding the document.location.href. I am using a cookie for storing the language the user prefers and then load the english or the swedish version depending on the language. The default language in the beginning is the same as the browser's language, and my index.jsp is the swedish one. The first time everything works fine. The problem is when the cookie exists already. The basic code is: if (language!=null && language!=""){ if (language=="en-US" || language=="en-us") document.location.href = "en/index.jsp"; } else{ //Explorer if (navigator.userLanguage) language = navigator.userLanguage; //other browsers else language = (navigator.language) ? navigator.language : navigator.userLanguage; if (language!=null && language!=""){ setCookie('language', language, 365, '/', 'onCheck'); if (language=="en-US" || language=="en-us") document.location.href = "en/index.jsp"; else if(language=="sv") document.location.href="index.jsp"; } } When the cookie exists we enter the first "if", and there, if the language is swedish it opens the default blabla/index.jsp page. When the language is set to engish it should open the blabla/en/index.jsp but instead it opens the blabla/en/en/index.jsp which of course is wrong. Does anyone know what I am doing wrong?? Thanks

• Why doesn't this simple regex match what I think it should?

  - by Kevin Stargel

  I have a data file that looks like the following example. I've added '%' in lieu of \t, the tab control character. 1234:56% Alice Worthington alicew% Jan 1, 2010 10:20:30 AM% Closed% Development Digg: Reddit: Update%% file-one.txt% 1.1% c:/foo/bar/quux Add%% file-two.txt% 2.5.2% c:/foo/bar/quux Remove%% file-three.txt% 3.4% c:/bar/quux Update%% file-four.txt% 4.6.5.3% c:/zzz ... many more records of the above form The records I'm interested in are the lines beginning with "Update", "Add", "Remove", and so on. I won't know what the lines begin with ahead of time, or how many lines precede them. I do know that they always begin with a string of letters followed by two tabs. So I wrote this regex: generate-report-for 1234:56 | egrep "^[[:alpha:]]+\t\t.+" But this matches zero lines. Where did I go wrong? Edit: I get the same results whether I use '...' or "..." for the egrep expression, so I'm not sure it's a shell thing.

• python: help defining/installing simple script to setup machine-specific information

  - by Jason S

  (This is related to scons but I think most of the following should be fairly general to python) I would like to define a python file/library that I put in a Well-Known Place somewhere on my computer that I can use to define machine-specific paths, and was looking for help on how to do this well, since I'm a beginner to Python & really only use it for my scons work. scons uses a SConstruct file which can execute python code. What I would like to do is something like this: My SConstruct file would contain this at the beginning: defaultEnv = JJJJJ.getMachineSpecificPaths() or (do both of these syntaxes work?) import JJJJJ defaultEnv = getMachineSpecificPaths() I define a JJJJJ.py file somewhere installed in the python dir which contains the following def getMachineSpecificPaths(): ... does something here, I don't know what ... that reads a file machine-specific-paths.txt (maybe it has the code Ross Rogers mentioned in my other question) located in the same directory as JJJJJ.py containing the following: machine-specific-paths.txt TI_C28_ROOT C:/appl/ti/ccs/?4.1.1/ccsv4/tools/co?mpiler/c2000 JSDB c:/bin/jsdb/jsdb.exe PYTHON_PATH c:/appl/python/2.6.4 The thing is, I don't really know much about the conventions in Python about where you put system-wide libraries and files. This is probably really simple to get right but I don't know how.

• How do I create a new project in TFS from an existing project (breaking history)?

  - by Lindsay

  My team is taking over a project from a previous team. We use a different TFS server than the original team, and we are also not interested in keeping the history of the project because we are accepting the latest version of the code as the beginning of our history with the project. Branching is not an option since we want to start our history from the current version of the code. We just want a fresh project with the existing code. I have not been able to create the new project from the old code successfully. I keep getting an error: "Source control cannot add the solution: Solution would span multiple workspaces" My process for attempting the new project creation: Create a workspace for the previous team's version of the code. Get latest version of that code into local mapped workspace directory Open the solution. Unbind all projects and solution. Close solution. Create a workspace for the new version of the code on our TFS server. Copy the unbound code on my local box to the new local workspace mapped folder. Open the solution from the new directory. "Add to source control" from the new solution. Then I get the error. I have tried removing the TFS security files out of the code directories in the unbound version and tried changing source control instead of adding to source control (but it just binds back to the original instead of letting me bind to the new). Is there any other way to do this besides recreating the solution/projects and adding back all the files and references? It doesn't seem like it should be this difficult... Any advice much appreciated!

• Play youtube video in full screen ?

  - by Madhup

  Hi all, First of all sorry, If somebody finds this question is repeated (haven't found any by myself). I am developing for an iPad application and trying to play youtube videos using this code: NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, youTubeUrl, 142.0, 129.5]; [wbView loadHTMLString:html baseURL:nil]; The code works fine when used in an iphone application (i.e. you touch on the webview and it starts playing the youtube video in fullscreen.) But when used in the iPad, on clicking the web view it starts playing the video in the web view itself and shows options to go to full screen, while I want to start the playback in the full screen from the beginning, like it does in the iPhone. Anybody having some ideas or people who have done it before please help. Thanks, Madhup

• problem with evolutionary algorithms degrading into simulated annealing: mutation too small?

  - by Schnalle

  i have a problem understanding evolutionary algorithms. i tried using this technique several times, but i always ran into the same problem: degeneration into simulated annealing. lets say my initial population, with fitness in brackets, is: A (7), B (9), C (14), D (19) after mating and mutation i have following children: AB (8.3), AC (12.2), AD (14.1), BC(11), BD (14.7), CD (17) after elimination of the weakest, we get A, AB, B, AC next turn, AB will mate again with a result around 8, pushing AC out. next turn, AB again, pushing B out (assuming mutation changes fitness mostly in the 1 range). now, after only a few turns the pool is populated with the originally fittest candidates (A, B) and mutations of those two (AB). this happens regardless of the size of the initial pool, it just takes a bit longer. say, with an initial population of 50 it takes 50 turns, then all others are eliminated, turning the whole setup in a more complicated simulated annealing. in the beginning i also mated canditates with themselves, worsening the problem. so, what do i miss? are my mutation rates simply too small and will it go away if i increase them? here's the project i'm using it for: http://stefan.schallerl.com/simuan-grid-grad/ yeah, the code is buggy and the interface sucks, but i'm too lazy to fix it right now - and be careful, it may lock up your browser. better use chrome, even thought firefox is not slower than chrome for once (probably the tracing for the image comparison pays off, yay!). if anyone is interested, the code can be found here. here i just dropped the ev-alg idea and went for simulated annealing. ps: i'm not even sure about simulated annealing - it is like evolutionary algorithms, just with a population size of one, right?

• how often should the entire suite of a system's unit tests be run?

  - by gerryLowry

  Generally, I'm still very much a unit testing neophyte. BTW, you may also see this question on other forums like xUnit.net, et cetera, because it's an important question to me. I apoligize in advance for my cross posting; your opinions are very important to me and not everyone in this forum belongs to the other forums too. I was looking at a large decade old legacy system which has had over 700 unit tests written recently (700 is just a small beginning). The tests happen to be written in MSTest but this question applies to all testing frameworks AFAIK. When I ran, via vs2008 "ALL TESTS", the final count was only seven tests. That's about 1% of the total tests that have been written to date. MORE INFORMATION: The ASP.NET MVC 2 RTM source code, including its unit tests, is available on CodePlex; those unit tests are also written in MSTest even though (an irrelevant fact) Brad Wilson later joined the ASP.NET MVC team as its Senior Programmer. All 2000 plus tests get run, not just a few. QUESTION: given that AFAIK the purpose of unit tests is to identify breakages in the SUT, am I correct in thinking that the "best practice" is to always, or at least very frequently, run all of the tests? Thank you. Regards, Gerry (Lowry)

• Long running operations (threads) in a web (asp.net) environment

  - by rrejc

  I have an asp.net (mvc) web site. As the part of the functions I will have to support some long running operations, for example: Initiated from user: User can upload (xml) file to the server. On the server I need to extract file, do some manipulation (insert into the db) etc... This can take from one minute to ten minutes (or even more - depends on file size). Of course I don't want to block the request when the import is running , but I want to redirect user to some progress page where he will have a chance to watch the status, errors or even cancel the import. This operation will not be frequently used, but it may happen that two users at the same time will try to import the data. It would be nice to run the imports in parallel. At the beginning I was thinking to create a new thread in the iis (controller action) and run the import in a new thread. But I am not sure if this is a good idea (to create working threads on a web server). Should I use windows services or any other approach? Initiated from system: - I will have to periodically update lucene index with the new data. - I will have to send mass emails (in the future). Should I implement this as a job in the site and run the job via Quartz.net or should I also create a windows service or something? What are the best practices when it comes to running site "jobs"? Thanks!

• Is it possible to use SqlGeography with Linq to Sql?

  - by cofiem

  I've been having quite a few problems trying to use Microsoft.SqlServer.Types.SqlGeography. I know full well that support for this in Ling to Sql is not great. I've tried numerous ways, beginning with what would the expected way (Database type of geography, CLR type of SqlGeography). This produces the NotSupportedException, which is widely discussed via blogs. I've then gone down the path of treating the geography column as a varbinary(max), as geography is a UDT stored as binary. This seems to work fine (with some binary reading and writing extension methods). However, I'm now running into a rather obscure issue, which does not seem to have happened to many other people. System.InvalidCastException: Unable to cast object of type 'Microsoft.SqlServer.Types.SqlGeography' to type 'System.Byte[]'. This error is thrown from an ObjectMaterializer when iterating through a query. It seems to only occur when the tables containing geography columns are included in a query implicitly (ie. using the EntityRef<> properties to do joins). System.Data.Linq.SqlClient.ObjectReaderCompiler.ObjectReader`2.MoveNext() My question: If I'm retrieving the geography column as varbinary(max), I might expect the reverse error: can't cast byte[] to SqlGeography. That I would understand. This I don't. I do have some properies on the partial LINQ to SQL classes that hide the binary conversion... could those be the issue? Any help appreciated, and I know there's probably not enough information.

• Understanding MongoDB (and NoSQL in general) and how to make the best use of it

  - by Earlz

  Hello, I am beginning to think that my next project I am wanting to do would work better with a NoSQL solution. The project would either involve a ton of 2-column tables or a ton of dynamic queries with dynamically generated columns in a traditional SQL database. So I feel a NoSQL database would be much cleaner. I'm looking at MongoDB and it looks pretty promising. Anyway, I'm attempting to make sense of it all. Also, I will be using MongoMapper in Ruby. Anyway though, I'm confused as to how to layout things in such a freeform database. I've read http://stackoverflow.com/questions/2170152/nosql-best-practices and the answer there says that normalization is usually bad in a NoSQL DB. So how would be the best way of laying out say a simple blog with users, posts, and comments? My natural thought was to have three collections for each and then link them by a unique ID. But this apparently is wrong? So, what are some of the ways to lay out such a thing? My concern with the answer given in the other question is, what if the author's name changed? You'd have to go through updating a ton of posts and comments. But is this an okay thing to do with NoSQL?

• Sorting a list in PHP

  - by Andy

  Alright, so I've just (almost) finished my first little php script. Basically all it does is handling forms. It writes whatever the user put in to the fields of the form to a text file, then I include that text file in the index of the little page I have set up. So, currently it writes to the beginning of the text file (but doesn't overwrite previous data). But, several users wants this list to be alphabetically sorted instead. So what I want to do is make whatever they submit fall into the list in alphabetical order. The thing here is also that all I use in the text file are divs. The list is basically 'divided' into 3 parts. 'Title', 'Link', and 'Poster'. All I have done is positioned them with css. So, can I sort this list (the titles, in this case) alphabetically and still have the 'link' and 'poster' information assigned the way they already are, but just with the titles sorted? It don't use databases at all on my site, so there is no database handling at all used in this script (mainly because I'm not experienced at all in this).

• Is JPA persistence.xml classpath located?

  - by Vinnie

  Here's what I'm trying to do. I'm using JPA persistence in a web application, but I have a set of unit tests that I want to run outside of a container. I have my primary persistence.xml in the META_INF folder of my main app and it works great in the container (Glassfish). I placed a second persistence.xml in the META-INF folder of my test-classes directory. This contains a separate persistence unit that I want to use for test only. In eclipse, I placed this folder higher in the classpath than the default folder and it seems to work. Now when I run the maven build directly from the command line and it attempts to run the unit tests, the persistence.xml override is ignored. I can see the override in the META-INF folder of the maven generated test-classes directory and I expected the maven tests to use this file, but it isn't. My Spring test configuration overrides, achieved in a similar fashion are working. I'm confused at to whether the persistence.xml is located through the classpath. If it were, my override should work like the spring override since the maven surefire plugin explains "[The test class directory] will be included at the beginning the test classpath". Did I wrongly anticipate how the persistence.xml file is located? I could (and have) create a second persistence unit in the production persistence.xml file, but it feels dirty to place test configuration into this production file. Any other ideas on how to achieve my goal is welcome.

• symfony doctrine build-sql error

  - by user313571

  I have some big problems with symfony and doctrine at the beginning of a new project. I have created database diagram with mysql workbench, inserted the sql into phpmyadmin and then I've tried symfony doctrine:build-schema to generate the YAML schema. It generates a wrong schema (relations don't have on delete/on update) and after this I've tried symfony doctrine:build --sql and symfony doctrine:insert-sql The insert-sql statement generates error (can't create table ... failing query alter table add constraint ....), so I've decided to take a look over the generated sql and I've found out some differences between the sql generated from mysql workbench (which works perfect, including relations) and the sql generated by doctrine. I'll be short from now: I have to tables, EVENT and FORM and a 1 to n relation (each event may have multiple forms) so the correct constraint (generated with workbench) is ALTER TABLE `form` ADD CONSTRAINT `fk_form_event1` FOREIGN KEY (`event_id`) REFERENCES `event` (`id`) ON DELETE CASCADE ON UPDATE CASCADE; doctrine generated statement is: ALTER TABLE event ADD CONSTRAINT event_id_form_event_id FOREIGN KEY (id) REFERENCES form(event_id); It's totally reversed and I am sure here is the error. What should I do? It's also correct like this?

• gcc, strict-aliasing, and horror stories

  - by Joseph Quinsey

  In http://stackoverflow.com/questions/2906365/gcc-strict-aliasing-and-casting-through-a-union I asked whether anyone had encountered problems with union punning through pointers. So far, the answer seems to be No. This question is broader: do you have any horror stories about gcc and strict-aliasing? Background: Quoting from AndreyT's answer in http://stackoverflow.com/questions/2771023/c99-strict-aliasing-rules-in-c-gcc/2771041#2771041: "Strict aliasing rules are rooted in parts of the standard that were present in C and C++ since the beginning of [standardized] times. The clause that prohibits accessing object of one type through a lvalue of another type is present in C89/90 (6.3) as well as in C++98 (3.10/15). ... It is just that not all compilers wanted (or dared) to enforce it or rely on it." Well, gcc is now daring to do so, with its -fstrict-aliasing switch. And this has caused some problems. See, for example, the excellent article http://davmac.wordpress.com/2009/10/ about a Mysql bug, and the equally excellent discussion in http://cellperformance.beyond3d.com/articles/2006/06/understanding-strict-aliasing.html. Some other less-relevant links: http://stackoverflow.com/questions/1225741/performance-impact-of-fno-strict-aliasing http://stackoverflow.com/questions/754929/strict-aliasing http://stackoverflow.com/questions/262379/when-is-char-safe-for-strict-pointer-aliasing http://stackoverflow.com/questions/725138/how-to-detect-strict-aliasing-at-compile-time So to repeat, do you have a horror story of your own? Problems not indicated by -Wstrict-aliasing would, of course, be preferred. And other C compilers are also welcome.

• Web Shop Schema - Document Db

  - by Maxem

  I'd like to evaluate a document db, probably mongo db in an ASP.Net MVC web shop. A little reasoning at the beginning: There are about 2 million products. The product model would be pretty bad for rdbms as there'd be many different kinds of products with unique attributes. For example, there'd be books which have isbn, authors, title, pages etc as well as dvds with play time, directors, artists etc and quite a few more types. In the end, I'd have about 9 different products with a combined column count (counting common columns like title only once) of about 70 to 100 whereas each individual product has 15 columns at most. The three commonly used ways in RDBMS would be: EAV model which would have pretty bad performance characteristics and would make it either impractical or perform even worse if I'd like to display the author of a book in a list of different products (think start page, recommended products etc.). Ignore the column count and put it all in the product table: Although I deal with somewhat bigger databases (row wise), I don't have any experience with tables with more than 20 columns as far as performance is concered but I guess 100 columns would have some implications. Create a table for each product type: I personally don't like this approach as it complicates everything else. C# Driver / Classes: I'd like to use the NoRM driver and so far I think i'll try to create a product dto that contains all properties (grouped within detail classes like book details, except for those properties that should be displayed on list views etc.). In the app I'll use BookBehavior / DvdBehaviour which are wrappers around a product dto but only expose the revelent Properties. My questions now: Are my performance concerns with the many columns approach valid? Did I overlook something and there is a much better way to do it in an RDBMS? Is MongoDb on Windows stable enough? Does my approach with different behaviour wrappers make sense?

• Protected and Private methods

  - by cabaret

  I'm reading through Beginning Ruby and I'm stuck at the part about private and protected methods. This is a newbie question, I know. I searched through SO for a bit but I couldn't manage to find a clear and newbie-friendly explanation of the difference between private and protected methods. The book gives two examples, the first one for private methods: class Person def initialize(name) set_name(name) end def name @first_name + ' ' + @last_name end private def set_name(name) first_name, last_name = name.split(/\s+/) set_first_name(first_name) set_last_name(last_name) end def set_first_name(name) @first_name = name end def set_last_name(name) @last_name = name end end In this case, if I try p = Person.new("Fred Bloggs") p.set_last_name("Smith") It will tell me that I can't use the set_last_name method, because it's private. All good till there. However, in the other example, they define an age method as protected and when I do fred = Person.new(34) chris = Person.new(25) puts chris.age_difference_with(fred) puts chris.age It gives an error: :20: protected method 'age' called for #<Person:0x1e5f28 @age=25> (NoMethodError) I honestly fail to see the difference between the private and protected methods, it sounds the same to me. Could someone provide me with a clear explanation so I'll never get confused about this again? I'll provide the code for the second example if necessary.

• accessing a value of a nested hash

I know that's an easy question, but perl is somewhat cryptic at the beginning. Thank you, St.

• Blackberry application works in simulator but not device

  - by Kai

  I read some of the similar posts on this site that deal with what seems to be the same issue and the responses didn't really seem to clarify things for me. My application works fine in the simulator. I believe I'm on Bold 9000 with OS 4.6. The app is signed. My app makes an HTTP call via 3G to fetch an XML result. type is application/xhtml+xml. In the device, it gives no error. it makes no visual sign of error. I tell the try catch to print the results to the screen and I get nothing. HttpConnection was taken right out of the demos and works fine in sim. Since it gives no error, I begin to reflect back on things I recall reading back when the project began. deviceside=true? Something like that? My request is simply HttpConnection connection = (HttpConnection)Connector.open(url); where url is just a standard url, no get vars. Based on the amount of time I see the connection arrows in the corner of the screen, I assume the app is launching the initial communication to my server, then either getting a bad result, or it gets results and the persistent store is not functioning as expected. I have no idea where to begin with this. Posting code would be ridiculous since it would be basically my whole app. I guess my question is if anyone knows of any major differences with device versus simulator that could cause something like http connection or persistent store to fail? A build setting? An OS restriction? Any standard procedure I may have just not known about that everyone should do before beginning device testing? Thanks

• SharePoint randomly replacing file names in web parts?

  - by nvuono

  Ok SharePoint is driving me crazy and I need to see if anyone has encountered a similar problem or knows of a solution: I have a content editor webpart with some HTML including links to PDF files that I've modified slightly to append an employee number querystring ie: <a href="http://moss.company.com/group/home/EPermits /Blank%20Form%20Templates/_blank_breach_permit.pdf?empNum=">New Breach Permit</a> And SharePoint seems to randomly replace the filename with aab04168 or some other similar characters: <a href="http://moss.company.com/group/home/EPermits /Blank%20Form%20Templates/aab04168?empNum=">New Breach Permit</a> After this happened a few times with no explanation I tried changing the content editor webpart to look directly at a documentLinks.html file located in the Shared Documents folder of the SharePoint site and guess what... SharePoint edited that document and replaced my filenames with random characters in there too! Figuring that filenames beginning with an underscore could be triggering some internal SharePoint procedures I've renamed all the files to remove the starting underscore--unfortunately the problem isn't immediately reproducible and I'm waiting right now to see if I run into any more trouble. edit: the underscore in the filename didn't help... my documentLinks.html wound up getting modified and all the hrefs were replaced with random characters again. Now I'm setting the hrefs in javascript with the filename text concatenated together from multiple strings. linkEle.href = ".../EPermits/Blank%20Form%20Templates/blank" + "_Chemical_Usage.pdf?empNum=" + empNumber;

• Microsoft products such as Visual Studio 2010 does not require to enter serial number

  - by MainMa

  Hi, I am member of WebsiteSpark and was member of DreamSpark. Both programs enable to download software and provide serial keys to use. Some software like Windows Server has an ISO file to download and a serial number displayed on the website which I must enter during installation. Some other software does not have any serial key. For example, when I downloaded Visual Studio 2010, there was just a link to an ISO file. During installation, there was no such a field as serial number (whereas Visual Studio 2008 had this field at the beginning of installation process). There is the same thing with SQL Server 2008 and Microsoft Expression Studio 3. Even when I've downloaded the public trial RTM version of Windows Seven Enterprise, there were no serial number to enter. I don't think that such expensive products as SQL Server 2008 Enterprise are delivered without serials and online validation, so I suppose that the serial is embedded into the product itself, either in installation binaries or in a separate config file, so is already in the ISO I download so I do not have to enter it. So my question is, how it is done technically? Is each 2 GBs ISO generated on-demand on the server to embed a serial each time this ISO is requested? I suppose that if it is done, it has a huge impact on servers performance (no caching, no streaming...), so what may be the techniques used behind? I want to implement the same feature in a product I intend to ship (to simplify installation by avoiding to ask to enter serial number), but I really don't see how to do it with low impact on server performance.
