  • VS 11 with std::future - Is this a bug?

    - by cooky451
    I recently installed the Visual Studio 11 Developer Preview. While playing with threads and futures, I came around this setup: #include <future> #include <iostream> int foo(unsigned a, unsigned b) { return 5; } int main() { std::future<int> f = std::async(foo, 5, 7); std::cout << f.get(); } So, very simple. But since there are two arguments for "foo", VS 11 doesn't want to compile it. (However, g++ does: http://ideone.com/ANrPj) (The runtime error is no problem: std::future exception on gcc experimental implementation of C++0x) (VS 11 errormessage: http://pastebin.com/F9Xunh2s) I'm a little confused right now, since this error seems extremely obvious to me, even if it is a developer preview. So my questions are: Is this code correct according to the C++11 standard? Is this bug already known/reported?

  • New MySQL 5.6 Developer Certification and Training

    - by Breanne Cooley
    For those of you who work with MySQL, we've got some great news for you! A wide range of Oracle MySQL teams, including training, engineering, sales consulting and members of MySQL Support, collected content for the new MySQL 5.6 Developer Certification exam. These team members assist developers and DBAs with MySQL questions on a daily basis. They understand what developers need to know to successfully develop applications against MySQL Server 5.6. The MySQL 5.6 Developer Certification Exam details are listed here.  Naturally, this certification process covers the same ground as Oracle's MySQL Training for Developers course, making it ideal for reviewing topics to help you pass the exam. More importantly, you will learn how to develop successful applications that use MySQL Server 5.6 as a data store.  -Diana Gray, Principal Curriculum Project Manager, Oracle University

  • Upload An Excel File in Classic ASP On Windows 2003 x64 Using Office 2010 Drivers

    - by alphadogg
    So, we are migrating an old web app from a 32-bit server to a newer 64-bit server. The app is basically a Classic ASP app. The pool is set to run in 64-bit and cannot be set to 32-bit due to other components. However, this breaks the old usage of Jet drivers and subsequent parsing of Excel files. After some research, I downloaded the 64-bit version of the new 2010 Office System Driver Beta and installed it. Presumably, this allows one to open and read Excel and CSV files. Here's the snippet of code that errors out. Think I followed the lean guidelines on the download page: Set con = Server.CreateObject("ADODB.Connection") con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.14.0;Data Source=" & strPath & ";Extended Properties=""Excel 14.0;""" con.Open Any ideas why? UPDATE: My apologies. I did forget the important part, the error message: ADODB.Connection error '800a0e7a' Provider cannot be found. It may not be properly installed. /vendor/importZipList2.asp, line 56 I have installed, and uninstalled/reinstalled twice.

  • Password Cracking in 2010 and Beyond

    - by mttr
    I have looked a bit into cryptography and related matters during the last couple of days and am pretty confused by now. I have a question about password strength and am hoping that someone can clear up my confusion by sharing how they think through the following questions. I am becoming obsessed about these things, but need to spend my time otherwise :-) Let's assume we have an eight-digit password that consists of upper and lower-case alphabetic characters, numbers and common symbols. This means we have 8^96 ~= 7.2 quadrillion different possible passwords. As I understand there are at least two approaches to breaking this password. One is to try a brute-force attack where we try to guess each possible combination of characters. How many passwords can modern processors (in 2010, Core i7 Extreme for eg) guess per second (how many instructions does a single password guess take and why)? My guess would be that it takes a modern processor in the order of years to break such a password. Another approach would consist of obtaining a hash of my password as stored by operating systems and then search for collisions. Depending on the type of hash used, we might get the password a lot quicker than by the bruteforce attack. A number of questions about this: Is the assertion in the above sentence correct? How do I think about the time it takes to find collisions for MD4, MD5, etc. hashes? Where does my Snow Leopard store my password hash and what hashing algorithm does it use? And finally, regardless of the strength of file encryption using AES-128/256, the weak link is still my en/decryption password used. Even if breaking the ciphered text would take longer than the lifetime of the universe, a brute-force attack on my de/encryption password (guess password, then try to decrypt file, try next password...), might succeed a lot earlier than the end of the universe. Is that correct? I would be very grateful, if people could have mercy on me and help me think through these probably simple questions, so that I can get back to work.

  • What's the best way to move to linux from windows for web development ?

    - by rajesh pillai
    I am primarily a programmer developing on windows based OS using c# as my primary language. I am evaluating Ubuntu Linux as an alternate platform and would like to know the best stack for doing web development on this. I had gone through the following thread Moving development from Windows to Linux but it doesn't answer my questions fully. Some of the points I am interested are outlined below PHP/Ruby/Python (What would you recommend?) Is Mono mature enough for any large scale development? Has anyone any real experience using Mono. IDE (including debugging support, intellisense, source control integration,Unit testing) Unit testing framework based on the language recommended Web framework if any. Load Testing tools Web server (I know there are many webservers, but would like to know which one is primarily used by most people) Your inputs is greatly appreciated. Thanks.

  • Changing the background colour of lines in the stack

    - by Mongus Pong
    I have just changed the colour scheme of my Visual Studio 2008 environment to have a dark backround with light text. This is so much easier on the eyes. The only problem is lines that are on the call stack... Those lines that are referred to in this thread here in visual studio some lines of code have light grey background while debugging These lines have a bright grey background, which against my light text means I cannot read the text at all. I have been through every single colour in Tools - Options - Fonts and Colours and cannot find one that matches. How can I change the background for lines on the current call stack?

  • How to install Eclipse + PHP Development Tools (PDT) + Debugger on Mac in The Year 2010

    - by aphex5
    I had a lot of trouble installing Eclipse and PDT on my system. It took two days, largely because all the tutorials I could find were out of date (written in 2008, it's 2010 now) and various steps they included were no longer necessary, broken, or irrelevant. I wanted to write my process here so it could be improved upon (via wiki) as time goes on. Install Eclipse without PHP plugin ("Eclipse Classic"). This will give you a complete Eclipse, which I find preferable, as the UI is more fleshed out (e.g. you get a default list of Perspectives, which helps you understand what Perspectives are.) Install PDT SDK with the Help Install New Software menu item. You'd think you'd be done here, but if you try to run something, it'll fail complaining of not having a debugger. Install the Zend Debugger. It'll fail if you try to use the Install New Software option, as many tutorials suggest ("No repository found containing osgi.bundle.org.zend.php.debug.debugger.5.3.7.v20091116".) Instead, download it from http://www.zend.com/en/community/pdt, and manually copy the features/ and plugins/ directory into your Eclipse install (these instructions are not written anywhere). Restart Eclipse Monkey with preferences for a while -- if you followed a previous tutorial and tried to manually add your php executable to Eclipse prefs (/usr/bin/php), remove it (PHP PHP Executables). Set one of the Zend Debugger executables to the default. If you've already tried to execute a .php file, remove the existing "Run" profile you (maybe weren't aware that you) created (Run Debug Configurations...). Eclipse works! You should be able to run a .php file as a script just fine.

  • Custom Build Step Paths Between x86 and x64 in Visual Studio

    - by Bob Somers
    For reference, I'm using Visual Studio 2010. I have a custom build step defined as follows: if exist "$(TargetDir)"server.dll copy "$(TargetDir)"server.dll "c:\program files (x86)\myapp\server.dll" This works great on my desktop, which is running 64-bit Windows. However, when I build on my laptop, c:\Program Files (x86)\ doesn't exist because it's running 32-bit Windows. I'd like to put in something that will work between both editions of Windows, since the project files are under version control and it's a real pain to change the paths every time I work on my laptop. If this were a *nix environment I'd just create a symlink and be done with it. Any ideas?

  • svn vs git for the sole developer? [closed]

    - by nattyP
    If I am sole developer (I do not work in a team) working from my laptop (Windows OS and Linux VM) and backing up data to the cloud (Dropbox etc), then is git still better than svn for my version control needs? I was thinking not since I wont need any of git's distributed features. But is git such a better approach to version control that I should consider moving anyway? With so many articles saying how people are moving from svn to git? I was wondering, if they are talking about large or open projects with teams of developers vs the sole developer. What do you think?

  • Linking IronPython to WPF

    - by DonnyD
    I just installed VS2010 and the great new IronPython Tools extension. Currently this extension doesn't yet generate event handlers in code upon double-clicking wpf visual controls. Is there anyone that can provide or point me to an example as to how to code wpf event handlers manually in python. I've had no luck finding any and I am new to visual studio. Upon generating a new ipython wpf project the auto-generated code is: import clr clr.AddReference('PresentationFramework') from System.Windows.Markup import XamlReader from System.Windows import Application from System.IO import FileStream, FileMode app = Application() app.Run(XamlReader.Load(FileStream('WpfApplication7.xaml', FileMode.Open))) and the XAML is: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="WpfApplication7" Height="300" Width="300"> <Button>Click Me</Button> </Window> Any help would be appreciated.

  • Report Builder Error (Input string was not in a correct format) when filtering data

    - by JVZ
    Issue: the user is getting an error “The requested list could not be retrieved because the query is not valid or a connection could not be made to the data source.” while trying to filter a reporting using Report Builder 2.0. When you expand the details the message is “Input string was not in a correct format” I verified that when the user clicks to see the filter values the query is being sent to the underlying database (by using profiler). When I build the same report [I'm a server admin] I have no issues and see all the filtered values, which leads me to believe this is a permissions issue. I believe I granted all the correct permissions, see below: Report Server Setup [Project Name] Data Sources Models […other folders] We are using SQL Server 2005.

  • Working on a virtual machine as a developer

    - by Johnny000
    In the company I'm currently working in, they decided that each developer will move to a VM desktop (Citrix/WinServer2012) an develop/test from there with restricted/no rights to install new software. The Server we will be working on are in a remote Datacenter. So i.e. if for some reason or another the internet brake down, we can't work till the connection is up again. As a developer I don't want to use windows as OS for my working/development environment as there is no need because we don't develop OS specific software. What good points could I raise in an argumentation against moving to the VMs beside the loss/restriction of freedom and the loss of connection to the internet?

  • Using the Search API with Sharepoint Foundation 2010 - 0 results

    - by MB
    I am a sharepoint newbee and am having trouble getting any search results to return using the search API in Sharepoint 2010 Foundation. Here are the steps I have taken so far. The Service Sharepoint Foundation Search v4 is running and logged in as Local Service Under Team Site - Site Settings - Search and Offline Availability, Indexing Site Content is enabled. Running the PowerShell script Get-SPSearchServiceInstance returns TypeName : SharePoint Foundation Search Description : Search index file on the search server Id : 91e01ce1-016e-44e0-a938-035d37613b70 Server : SPServer Name=V-SP2010 Service : SPSearchService Name=SPSearch4 IndexLocation : C:\Program Files\Common Files\Microsoft Shared\Web Server Exten sions\14\Data\Applications ProxyType : Default Status : Online When I do a search using the search textbox on the team site I get a results as I would expect. Now, when I try to duplicate the search results using the Search API I either receive an error or 0 results. Here is some sample code: using Microsoft.SharePoint.Search.Query; using (var site = new SPSite(_sharepointUrl, token)) { // FullTextSqlQuery fullTextSqlQuery = new FullTextSqlQuery(site) { QueryText = String.Format("SELECT Title, SiteName, Path FROM Scope() WHERE \"scope\"='All Sites' AND CONTAINS('\"{0}\"')", searchPhrase), //QueryText = String.Format("SELECT Title, SiteName, Path FROM Scope()", searchPhrase), TrimDuplicates = true, StartRow = 0, RowLimit = 200, ResultTypes = ResultType.RelevantResults //IgnoreAllNoiseQuery = false }; ResultTableCollection resultTableCollection = fullTextSqlQuery.Execute(); ResultTable result = resultTableCollection[ResultType.RelevantResults]; DataTable tbl = new DataTable(); tbl.Load(result, LoadOption.OverwriteChanges); } When the scope is set to All Sites I retrieve an error about the search scope not being available. Other search just return 0 results. Any ideas about what I am doing wrong?

Can i get the output like below by using a query? I need the dates in one month to be columns and the value of the date columns will be values in the status column. The number of date records per studentID is the same its the number of dates in the attendanceDate filed that is unknown. studentID---------2010-03-17--------2010-03-19------2010-03-20 1004-----------------------------0----------------------0--------------------1 etc. This is for a creating a report so I need to do it in a query.

  • Web development for people who mainly do client side..

    - by kamziro
    Okay, I'm sure there are a lot of us that has plenty of experience developing c++/opengl/objective C on the iPhone, java development on android, python games, etc (any client side stuff) while having little to no experience on web-based development. So what skillset should one learn in order to be able to work on web projects, say, to make a facebook clone (I kid), or maybe a startup that specializes on connecting random fashionistas with pics etc. I actualy do have some experience with C#/VB.net back-end development a while back, but as part of a team, I had a lot of support from the senior devs. Is C# considered a decent web development language?

    Being new to node js magic world, i'm wondering how does a web application's setup look like on a real production server? So far all tutorials, create the js file that is started from a console...and that's it. Anyone has created a real world web app that uses node js in the back end? Can you please describe how is it setup, and how reliable this infrastructure is ? I'm coming from the asp.net and php world that require heavy web servers...and can't have a clear idea about node stuff.

  • Any info about book "Unix Internals: The New Frontiers" by Uresh Vahalia 2nd edition (Jan 2010)

    - by claws
    This summer I'm getting into UNIX (mostly *BSD) development. I've graduate level knowledge about operating systems. I can also understand the code & read from here and there but the thing is I want to make most of my time. Reading books are best for this. From my search I found that these two books The Design and Implementation of the 4.4 BSD Operating System "Unix Internals: The New Frontiers" by Uresh Vahalia are like established books on UNIX OS internals. But the thing is these books are pretty much outdated. yay!! Lucky me. "Unix Internals: The New Frontiers" by Uresh Vahalia 2 edition (Jan 2010) is released. I've been search for information on this book. Sadly, Amazon says "Out of Print--Limited Availability" & I couldn't find any info regarding this book. This is the information I'm looking for: Table of Contents Whats new in this edition? Where the hell can I buy soft-copy of this book? I really cannot afford buying a hardcopy. How can I contact the author? I've lot of hopes & expectations on this book. I've been waiting for its release for a long time. I've sent random mails to & & requesting to have a proper website for this book. I even contacted publisher for any further information but no replies from any one. If you have any other books that you think will help me. I again repeat, I want to get max possible out of these 2.5 months summer.

  • Windsor IHandlerSelector in RIA Services Visual Studio 2010 Beta2

    - by Savvas Sopiadis
    Hi everybody! I want to implement multi tenancy using Windsor and i don't know how to handle this situation: i succesfully used this technique in plain ASP.NET MVC projects and thought incorporating in a RIA Services project would be similar. So i used IHandlerSelector, registered some components and wrote an ASP.NET MVC view to verify it works in a plain ASP.NET MVC environment. And it did! Next step was to create a DomainService which got an IRepository injected in the constructor. This service is hosted in the ASP.NET MVC application. And it actually ... works:i can get data out of it to a Silverlight application. Sample snippet: public OrganizationDomainService(IRepository<Culture> cultureRepository) { this.cultureRepository = cultureRepository; } Last step is to see if it works multi-tenant-like: it does not! The weird thing is this: using some line of code and writing debug messages in a log file i verified that the correct handler is selected! BUT this handler seems not to be injected in the DomainService. I ALWAYS get the first handler (that's the logic in my SelectHandler) Can anybody verify this behavior? Is injection not working in RIA Services? Or am i missing something basic?? Development environment: Visual Studio 2010 Beta2 Thanks in advance

  • How would I pursue a track in front-end web development?

    - by Koviko
    I've recently been put on heavy JavaScript projects and have become fond of the front-end world in comparison to the back-end. I have always been good at proper markup and CSS, and coupled with AJAX, pretty animations, and dynamically generated content, it's become a much more interesting and flashy world for me. I would like to be able to continue to hone my craft in the same way that I was able to become proficient at back-end development with PHP: getting paid to do it. How would I market myself as a front-end web developer with a strong interest in dynamic JavaScript-driven websites? Due to my strong background in back-end development, how would I find the companies that wouldn't waste my front-end skill set on simple HTML/CSS development? And as a bonus, how would I apply this to being a contractor/freelance developer rather than a salaried employee? While I like the idea of being able to remain a part of my creations, I also dislike the maintenance phase of projects.

  • Implementing Multitasking on an iPhone/iOS4 Web App

    - by Peter Watts
    I am looking to build a web app that implements background audio and fast app switching. These features work out of the box, when run as regular Safari web pages, but as soon as you add the web-app-capable tag, and try to run in full screen mode, this functionality breaks. I did some testing and even the most basic web app will reload every time when you switch back to it. And seeing as it's a web app, we can't exactly implement the multitasking API. Has anyone found a work around? This isn't a deal-breaker, as you can just avoid full screen mode, but then you also lose the ability to use your own icon in the app switch tray. Perhaps this explains a lack of full screen mode in YouTube's new web app....
