  • How? Encrypt and Decrypt user membership passwords in ASP.NET

    - by smdrager
    We are creating a new site using ASP.NET membership provider for user registration and log in. Our old system encrypted user passwords so that we could recover them if we needed to. I am having a great deal of trouble figuring out if it is possible to use ASP.NET membership functions to simply encrypt the password when the user registers and then unencrypt it so I can see it. Documentation for this is neigh non-existant. I know how to configure Web.config to have it store passwords as encrypted ala passwordFormat="Hashed" in the provider and assigning a validationKey in the machineKey, however it seems like the password still gets hashed (though perhaps it is just well encrypted). Either way I cannot decifer how the password can be recovered (by us) if neccessary. Thanks!

  • c++11 atomic ordering: extended total order memory_order_seq_cst for locks

    - by itaj
    There's this note in c++11 29.3-p3: [ Note: Although it is not explicitly required that S include locks, it can always be extended to an order that does include lock and unlock operations, since the ordering between those is already included in the "happens before" ordering. - end note ] What does it mean by "always"? I can understand that any certain implementation can be designed to support such an extended S. But in some general implementation that wasn't designed for it, I don't see that S can be extended so. I had sent this question to comp.std.c++ but got no answers there. http://groups.google.com/group/comp.std.c++/browse_frm/thread/5242fa70d0594d1b#

  • MySQL Import Database Error because of Extended Inserts

    - by Castgame
    Hello all, I'm importing a 400MB(uncompressed) MySQL database. I'm using BIGDUMP, and I am getting this error: Stopped at the line 387. At this place the current query includes more than 300 dump lines. That can happen if your dump file was created by some tool which doesn't place a semicolon followed by a linebreak at the end of each query, or if your dump contains extended inserts. Please read the BigDump FAQs for more infos. I believe the file does contain Extended Inserts, however I have no way to regenerate the database as it has been deleted from the old server. How can I import this database or convert it to be imported? Thanks for any help. Best Nick EDIT: It appears the only viable answer is to separate the extended inserts, but I still need help figuring out how to split the file as the answer below suggests. Please help. Thank you.

  • Good way to fetch XML from a remote URL, convert it to HTML and display it in a ASP.NET-page

    - by Binary255
    Hi, The use case I want to achive is. 1. Fetch XML from a remote URL. 2. Convert it to HTML using XSLT 3. Insert the generated HTML at a position in my ASP.NET web forms page. Alternative on the above, if 1 returns a 404: 2. Generate HTML which display an error message to the user. Only step 3 is left as I've completed 1-2. As there are logic for handling the two execution paths and performing the XSLT-transformation I thought it would be suitable to keep it in the code-behind file. What's a good, clean way of inserting generated HTML at a position in my ASP.NET web forms page?

  • What's the most simple way to retrieve all data from a table and save it back in .NET 3.5?

    - by zoman
    I have a number of tables containing some basic (business related) mapping data. What's the most simple way to load the data from those tables, then save the modified values back. (all data should be replaced in the tables) An ORM is out of question as I would like to avoid creating domain objects for each table. The actual editing of the data is not an issue. (it is exported into Excel where the data is edited, then the file is uploaded with the modified data) The technology is .NET 3.5 (ASP.NET MVC) and SQL Server 2005. Thanks.

  • Does Windows 7 have .NET 4 installed by default?

    - by Nasenbaer
    I offered software where .NET 4.0 is needed and promised, that Windows 7 already comes with this framework. If not, the user can use the integrated "Windows Update" function to install the framework. My client said to me there is no Framework on Windows 7 Professional installed already. What are details about the situation of Windows 7 and is there an option to install .NET by using the update function of Windows 7?

  • Oracle Utilities Application Framework V4.1 Group Fix 4 available

    - by ACShorten
    Oracle Utilities Application Framework V4.1 Group Fix 4 is available from My Oracle Support as Patch 13523301. This Group Fix contains a number of enhancements and keeps fixes up to date to the latest patch level. The enhancements included in this Group Fix include: UI Hints - In previous group fixes of the Oracle Utilities Application Framework the infrastructure to support UI Hints was introduced. This group fix completes the release of this functionality. Prior to this enhancement, products and implementers typically would build at least one UI Map per Business Object to display and/or maintain the object. Whilst, this can be generated using the UI Map maintenance function and stored, this enhancement allows additional tags and elements to be added to the Business Object directly to allow dynamic generation of the UI Map for maintenance and viewing the object. This reduces the need to generate and build a UI Map at all for that object. This will reduce maintenance effort of maintaining the product and implementation by eliminating the need to maintain the HTML for the UI Map. This also allows lower skilled personnel to maintain the system. Help and working examples are available from the View schema attributes and node names option from the Schema Tips dashboard zone. For example: Note: For examples of the hints, refer to an of the following Business Objects F1_OutcomeStyleLookup, F1-TodoSumEmailType, F1-BOStatusReason or F1-BIGeneralMasterConfig. Setting batch log file names -  By default the batch infrastructure supplied with the Oracle Utilities Application Framework sets the name and location of the log files to set values. In Group Fix 4 a set of user exits have been added to allow implementers and partners to set their own filename and location.  Refer to the Release Notes in the download for more details.

  • CoffeeScript Test Framework

    - by Liam McLennan
    Tonight the Brisbane Alt.NET group is doing a coding dojo. I am hoping to talk someone into pairing with me to solve the kata in CoffeeScript. CoffeeScript is an awesome language, half javascript, half ruby, that compiles to javascript. To assist with tonight’s dojo I wrote the following micro test framework for CoffeeScript: <html> <body> <div> <h2>Test Results:</h2> <p class='results' /> </div> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script> <script type="text/coffeescript"> # super simple test framework test: { write: (s) -> $('.results').append(s + '<br/>') assert: (b, message...) -> test.write(if b then "pass" else "fail: " + message) tests: [] exec: () -> for t in test.tests test.write("<br/><b>$t.name</b>") t.func() } # add some tests test.tests.push { name: "First Test" func: () -> test.assert(true) } test.tests.push { name: "Another Test" func: () -> test.assert(false, "You loose") } # run them test.exec(test.tests) </script> <script type="text/javascript" src="coffee-script.js"></script> </body> </html> It’s not the prettiest, but as far as I know it is the only CoffeeScript test framework in existence. Of course, I could just use one of the javascript test frameworks but that would be no fun. To get this example to run you need the coffeescript compiler in the same directory as the page.

  • Creating a Website Without a Framework [closed]

    - by James Jeffery
    I've been using PHP Frameworks for so long that I've actually forgot the "best practices" for create websites without one. Usually I will use Symfony, or more recently I've been using Laravel. A client wants a very simple website, but with certain parts of it dynamic. Due to the nature of the site using Wordpress, or a Framework, is out of the question. I'm a sucker for priding myself on my code, but I feel like I'm asking such a basic question that it's killing me to ask. But, what are the best practices for creating websites without a Framework? I like to live by the K.I.S.S (Keep It Simple Stupid!) method of thinking. So, my idea was to just create the .php pages that are required, do any page processing or database interaction on that page, then have the HTML below the closing PHP tag. I would have any helpers/functions in a functions.php file. This is what I remember doing way before I was using Frameworks, and to me it seems like a very old school way of doing things. I've not created a site without a Framework for literally 2+ years, so I've lost my way with the basics. Any advice would be greatly appreciated.

  • Introducing the New Boot Framework in CE 7

    - by Kate Moss' Open Space
    CE 7 introduces a new boot loader framework, BLDR (platform\common\src\common\bldr\). Some people like its powerful and flexbility, others may feel its too complicate as a boot loader framework. Despite to the favor, it is already there; so let's take a look at its features. Unlike the previous BL framwork (CE7 still provides it in platform\common\src\common\boot\) is a monolithic library, the new framework has more architecture structure. It not only defines main body but also provides rich components, such as filesystem (BinFS/FAT), download transportations, display, logging and block devices: bios INT13, FAL, IDE, Flash ( and etc. Note that in the block device category, the FAL is for legacy FMD/FAL, Flash is for latest MSFlash. Some of you may have encountered MSFlash MDD/PDD compatible partition is hard to created in bootloader and now it provides a clean solution! (Since this is a big topic, I will introduce it in future post) Today, I am going to show you some basic helper components - Image Loading functions. When OS image stored in the block device, it can be a file format, says your NK.BIN in the FAT volume or a RAW format, says the image is programmed to a BINFS partition. For the first one you can use BootFileSystemReadBinFile (platform\common\src\common\bldr\fileSystem\utils\fileSystemReadBinFile.c) and use BootBlockLoadBinFsImage (platform\common\src\common\bldr\block\utils\loadBinFs.c) to load from a partition. Need a sample code? No problem, the BootLoaderLoadOs in platform\cepc\src\boot\bldr\loados.c just provide a perfect example.

  • Resons why I'm using php rather then asp.net [closed]

    - by spirytus
    I have basic idea of how asp .Net works, but finds all framework hard to use if you are a newbie. I found compiling, web applications vs websites and all that stuff you should know to program in asp .net a bit tedious and so personally I go with php to create small, to medium applications for my clients. There are couple of reasons for it: php is easy scripting language, top to bottom and you done. You still can create objects, classes and if you have idea of MVC its fairly easy to create basic structure yourself so you can keep you presentation layer "relatively" clean. Although I find myself still mixing basic logic in my view's, I am trying to stick to booleans, and for each loops. ASP .net keeps it cleaner as far as I know and I agree that this is great. Heaps of free stuff for php and lots of help everywhere Although choice of IDE's for php is very limited, I still don't have to be stuck with VisualStudio. Lets be honest.. you can program in whatever you like but does anyone uses anything else other than VS? For basic applications I create, Visual Studio doesn't come even close to notepad :) / phpEdit (or similar) combination. It lacks of many features I constantly use, although armies of developers are using it and it must be for good reason. Personally not a big fan of VS though. Being on the market for that long should make editing much easier. I know .Net comes with awesome set of controls, validators etc. which is truly awesome. For me the problem starts if I want my validator to behave slightly different way and lets say fade in/out error messages. I know its possible to extend it behavior, plug into lifecycle and output different JS to the client and so on. I just never see it happen in places I work, and honestly, I don't even think most of .net developers I worked with during last couple of years would know how to do that. In php I have to grab some plugin for jQuery and use it for validation, which is fairly easy task once you had done it before. Again I'm sure its easy for .net gurus, but for newbie like me its almost impossible. I found that many asp .net programmers are very limited in what they are able to do and basically whack together .net applications using same lame set of controls, not even bothering in looking into how it works and what if? Now I don't want to anger anyone :) I know there is huge number of excellent .Net developers who know their stuff and are able to extend controls and do all that magic in no time. I found it a bit annoying though that many of them stick to what is provided without even trying to make it better. Nothing against .net here, just a thought really :) I remember when asp.net came out the idea was that front-end people will not be able to screw anything up and do their fron-end stuff without worrying what happens behind. Now its never that easy and I always tend to get server side people to fix this and that during development. Things like ID's assigned to controls can very easily make your application break and if someone is pure HTML guy using VS its easy to break something. Thats my thoughs on php and .net and reasons why for my work I go with php. I know that once learned asp .net is awesome technology and summing all up php doesn't even come close to it. For someone like me however, individually developing small basic applications for clients, php seems to work much better. Please let me know your thoughts on the above :)

  • Multi-threaded .NET application blocks during file I/O when protected by Themida

    - by Erik Jensen
    As the title says I have a .NET application that is the GUI which uses multiple threads to perform separate file I/O and notice that the threads occasionally block when the application is protected by Themida. One thread is devoted to reading from serial COM port and another thread is devoted to copying files. What I experience is occasionally when the file copy thread encounters a network delay, it will block the other thread that is reading from the serial port. In addition to slow network (which can be transient), I can cause the problem to happen more frequently by making a PathFileExists call to a bad path e.g. PathFileExists("\\\\BadPath\\file.txt"); The COM port reading function will block during the call to ReadFile. This only happens when the application is protected by Themida. I have tried under WinXP, Win7, and Server 2012. In a streamlined test project, if I replace the .NET application with a MFC unmanaged application and still utilize the same threads I see no issue even when protected with Themida. I have contacted Oreans support and here is their response: The way that a .NET application is protected is very different from a native application. To protect a .NET application, we need to hook most of the file access APIs in order to "cheat" the .NET Framework that the application is protected. I guess that those special hooks (on CreateFile, ReadFile...) are delaying a bit the execution in your application and the problem appears. We did a test making those hooks as light as possible (with minimum code on them) but the problem still appeared in your application. The rest of software protectors that we tried (like Enigma, Molebox...) also use a similar hooking approach as it's the only way to make the .NET packed file to work. If those hooks are not present, the .NET Framework will abort execution as it will see that the original file was tampered (due to all Microsoft checks on .NET files) Those hooks are not present in a native application, that's why it should be working fine on your native application. Oreans support tried other software protectors such as Enigma Protector, Engima VirtualBox, and Molebox and all exhibit the exact same problem. What I have found as a work around is to separate out the file copy logic (where the file exists call is being made) to be performed in a completely separate process. I have experimented with converting the thread functions from unmanaged C++ to VB.NET equivalents (PathFileExists - System.IO.File.Exists and CreateFile/ReadFile - System.IO.Ports.SerialPort.Open/Read) and still see the same serial port read blocked when the file check or copy call is delayed. I have also tried setting the ReadFile to work asynchronously but that had no effect. I believe I am dealing with some low-level windows layer that no matter the language it exhibits a block on a shared resource -- and only when the application is executing under a single .NET process protected by Themida which evidently installs some hooks to allow .NET execution. At this time converting the entire application away from .NET is not an option. Nor is separating out the file copy logic to a separate task. I am wondering if anyone else has more knowledge of how a file operation can block another thread reading from a system port. I have included here example applications that show the problem: https://db.tt/cNMYfEIg - VB.NET https://db.tt/Y2lnTqw7 - MFC They are Visual Studio 2010 solutions. When running the themida protected exe, you can see when the FileThread counter pauses (executing the File.Exists call) while the ReadThread counter also pauses. When running non-protected visual studio output exe, the ReadThread counter does not pause which is how we expect it to function. Thanks!

  • JavaScript Data Binding Frameworks

    - by dwahlin
    Data binding is where it’s at now days when it comes to building client-centric Web applications. Developers experienced with desktop frameworks like WPF or web frameworks like ASP.NET, Silverlight, or others are used to being able to take model objects containing data and bind them to UI controls quickly and easily. When moving to client-side Web development the data binding story hasn’t been great since neither HTML nor JavaScript natively support data binding. This means that you have to write code to place data in a control and write code to extract it. Although it’s certainly feasible to do it from scratch (many of us have done it this way for years), it’s definitely tedious and not exactly the best solution when it comes to maintenance and re-use. Over the last few years several different script libraries have been released to simply the process of binding data to HTML controls. In fact, the subject of data binding is becoming so popular that it seems like a new script library is being released nearly every week. Many of the libraries provide MVC/MVVM pattern support in client-side JavaScript apps and some even integrate directly with server frameworks like Node.js. Here’s a quick list of a few of the available libraries that support data binding (if you like any others please add a comment and I’ll try to keep the list updated): AngularJS MVC framework for data binding (although closely follows the MVVM pattern). Backbone.js MVC framework with support for models, key/value binding, custom events, and more. Derby Provides a real-time environment that runs in the browser an in Node.js. The library supports data binding and templates. Ember Provides support for templates that automatically update as data changes. JsViews Data binding framework that provides “interactive data-driven views built on top of JsRender templates”. jQXB Expression Binder Lightweight jQuery plugin that supports bi-directional data binding support. KnockoutJS MVVM framework with robust support for data binding. For an excellent look at using KnockoutJS check out John Papa’s course on Pluralsight. Meteor End to end framework that uses Node.js on the server and provides support for data binding on  the client. Simpli5 JavaScript framework that provides support for two-way data binding. WinRT with HTML5/JavaScript If you’re building Windows 8 applications using HTML5 and JavaScript there’s built-in support for data binding in the WinJS library.   I won’t have time to write about each of these frameworks, but in the next post I’m going to talk about my (current) favorite when it comes to client-side JavaScript data binding libraries which is AngularJS. AngularJS provides an extremely clean way – in my opinion - to extend HTML syntax to support data binding while keeping model objects (the objects that hold the data) free from custom framework method calls or other weirdness. While I’m writing up the next post, feel free to visit the AngularJS developer guide if you’d like additional details about the API and want to get started using it.
