  • TFSBuild.Proj and Manual SQL Server Work Help?

    - by ScSub
    Using the VS 2008 GDR update, I have created a database project. I have created a SQL Server deployment package. I have created a database unit test. Using some wizards, the stuff got into my tfsbuild.proj file so near the end of the automated build process a database is created. I lack a little control of the whole process, I now see. What I would like to do is manually deploy the DB, run 3 custom scripts against the DB, and then manually start the DB unit test. I have other non-DB unit tests that already run. I do not want to use VSMDI or ordered unit test stuff because in out multi-developer environment it gets messy. Help!

  • Redirecting from ASP.NET WebForms to MVC

    - by Paul Gordon
    Hi there, We have a large existing ASP.NET WebForms application, but we are now moving over to MVC. Rather than go through a painful process of trying to integrate MVC into the existing app, we're looking at creating a brand new VS project to completely isolate the new code. As a first step, we are wanting to use the existing login process of the WebForms app, then redirect over to the MVC app. Does anyone know of an easy way to do this (i.e. redirect from a WebForms project to the MVC project, in the same VS solution)? All the information I've found so far suggests either starting from scratch in MVC, or combing MVC into the existing Webforms project - neither of which is very feasible. Many thanks, Paul

  • .NET: IOException for permissions when creating new file?

    - by Rosarch
    I am trying to create a new file and write XML to it: FileStream output = File.Create(Path.Combine(PATH_TO_DATA_DIR, fileName)); The argument evaluates to: C:\path\to\Data\test.xml The exception is: The process cannot access the file 'C:\path\to\Data\test.xml' because it is being used by another process. What am I doing wrong here? UPDATE: This code throws the same exception: StreamWriter writer = new StreamWriter(Path.Combine(PATH_TO_DATA_DIR, fileName)); UPDATE 2: The file I am trying to create does not exist in the file system. So how can be it in use?

  • py2app prescripts

    - by yoav.aner
    The py2app documentation mentions prescripts, being run by __boot__.py prior to the main python script. I couldn't find a way to easily specify any prescript on the setup.py file or build process. I did however manage to 'hack' __boot__.py manually and add another _run(prescript) command before my main _run(main_script) and it seemed to work fine. It would however be much better using the standard py2app build process. What I'm essentially trying to do is monkey-patch my sites-packages.zip file prior to the main script being launched. The prescript essentially checks for updates on the server, and if there are any, downloads them, and then overwrites the site-packages.zip file. Much quicker than having to re-install the application from scratch. Any ideas?

  • Loading dynamic content and rewrite URL on Hashchange event with Jquery Mobile

    - by user3611500
    I'm building a mobile version for my website using Jquery Mobile API. The framework provides automate AJAX navigation processing. But as far as i know it require "real" pages for loading purpose. What i want to do is override the automate navigation process of it and process the hashchange on my own. But i can't not rewrite the url using window.hashChange, which is running well on my non-mobile website version : $(function () { $(window).off().hashchange(function () { if (location.hash.length > 1) { PageSelect(); } }); $(window).hashchange(); }); I just only want to take advantage on jquery mobile interfaces, i don't want anything with its automate ajax navigation stuff ! I tried to disable it using ajaxEnabled() but got no luck.

  • <100% Test coverage - best practices in selecting test areas

    - by Paul Nathan
    Suppose you're working on a project and the time/money budget does not allow 100% coverage of all code/paths. It then follows that some critical subset of your code needs to be tested. Clearly a 'gut-check' approach can be used to test the system, where intuition and manual analysis can produce some sort of test coverage that will be 'ok'. However, I'm presuming that there are best practices/approaches/processes that identify critical elements up to some threshold and let you focus your test elements on those blocks. For example, one popular process for identifying failures in manufacturing is Failure Mode and Effects Analysis. I'm looking for a process(es) to identify critical testing blocks in software.

  • 301 versus inline rewrites

    - by Kristoffer S Hansen
    I'm in the process of adding 'pretty' URLs to an existing CMS, the menu is auto generated and the new 'pretty' URLs are to be handled independently as a seperate module. The auto-generated menu allways has URLs that look like this index.php?menu_id=n which ofcourse we would like to see as eg. /news or /products I'm currently at the point where I have to decide if I'm going to rewrite all output of the current system or simply put in a hook where I redirect to the 'pretty' URL. To put it differently, should i connect to the database, fetch all 'pretty' URLs, run through the existing output from WYSIWYG's, news modules, forums etc. and do some str_replace or other string manipulation (which I think would be a rather tedious and boring process), or should I simply hook in and throw a 301 redirecting index.php?menu_id=3 to /news will Google (or other search engines) penalize me for having 301's in the menus?

  • android content provider robustness on provider crash

    - by user1298992
    On android platforms (confirmed on ICS), if a content provider dies while a client is in the middle of a query (i.e. has a open cursor) the framework decides to kill the client processes holding a open cursor. Here is a logcat output when i tried this with a download manager query that sleeps after doing a query. The "sleep" was to reproduce the problem. you can imagine it happening in a regular use case when the provider dies at the right/wrong time. And then do a kill of com.android.media (which hosts the downloadProvider). "Killing com.example (pid 12234) because provider com.android.providers.downloads.DownloadProvider is in dying process android.process.media" I tracked the code for this in ActivityManagerService::removeDyingProviderLocked Is this a policy decision or is the cursor access unsafe after the provider has died? It looks like the client cursor is holding a fd for an ashmem location populated by the CP. Is this the reason the clients are killed instead of throwing an exception like Binders when the server (provider) dies ?

  • MapViewOfFile shared between 32bit and 64bit processes

    - by MK
    Hi, I'm trying to use MapViewOfFile in a 64 bit process on a file that is already mapped to memory of another 32 bit process. It fails and gives me an "access denied" error. Is this a known Windows limitation or am I doing something wrong? Same code works fine with 2 32bit processes. The code sort of looks like this: hMapFile = OpenFileMapping(FILE_MAP_ALL_ACCESS, FALSE, szShmName); if (NULL == hMapFile) { /* failed to open - create new (this happens in the 32 bit app) */ SECURITY_ATTRIBUTES sa; sa.nLength = sizeof(SECURITY_ATTRIBUTES); sa.bInheritHandle = FALSE; /* give access to members of administrators group */ BOOL success = ConvertStringSecurityDescriptorToSecurityDescriptor( "D:(A;OICI;GA;;;BA)", SDDL_REVISION_1, &(sa.lpSecurityDescriptor), NULL); HANDLE hShmFile = CreateFile(FILE_FAXCOM_SHM, FILE_ALL_ACCESS, 0, &sa, OPEN_ALWAYS, 0, NULL); hMapFile = CreateFileMapping(hShmFile, &sa, PAGE_READWRITE, 0, SHM_SIZE, szShmName); CloseHandle(hShmFile); } // this one fails in 64 bit app pShm = MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS, 0, 0, SHM_SIZE);

  • what is the best way to generate fake data for classification problem ?

    - by Berkay
    i'm working on a project and i have a subset of user's key-stroke time data.This means that the user makes n attempts and i will use these recorded attempt time data in various kinds of classification algorithms for future user attempts to verify that the login process is done by the user or some another person. (Simply i can say that this is biometrics) I have 3 different times of the user login attempt process, ofcourse this is subset of the infinite data. until now it is an easy classification problem, i decided to use WEKA but as far as i understand i have to create some fake data to feed the classification algorithm. can i use some optimization algorithms ? or is there any way to create this fake data to get min false positives ? Thanks

  • Unable to install juju-gui locally?

    - by Maciek
    I'm attempting to setup juju-gui in a VM running Ubuntu 13.10 x64 Server. I intend to see if it's possible to deploy an openstack "all in one" node, using this method in that particular VM. I've installed and bootstrapped juju in a local environment : $sudo apt-get install juju-core $sudo apt-get install juju-local $juju switch local $sudo juju bootstrap Next I've executed the following : $juju deploy juju-gui $juju expose juju-gui $watch juju status I was expecting to see juju-gui open up some ports and become available via a web-browser but nothing like that happened - why? how do I fix that? I believe I've managed to follow the deployment guides to the letter? Are there any detailed walkthroughs regarding deploying openstack on 13.10, using juju? Cheers :)

  • Memory mapped files causes low physical memory

    - by harik
    I have a 2GB RAM and running a memory intensive application and going to low available physical memory state and system is not responding to user actions, like opening any application or menu invocation etc. How do I trigger or tell the system to swap the memory to pagefile and free physical memory? I'm using Windows XP. If I run the same application on 4GB RAM machine it is not the case, system response is good. After getting choked of available physical memory system automatically swaps to pagefile and free physical memory, not that bad as 2GB system. To overcome this problem (on 2GB machine) attempted to use memory mapped files for large dataset which are allocated by application. In this case virtual memory of the application(process) is fine but system cache is high and same problem as above that physical memory is less. Even though memory mapped file is not mapped to process virtual memory system cache is high. why???!!! :( Any help is appreciated. Thanks.

  • Announcing the New Windows Azure Web Sites Shared Scaling Tier

    - by Clint Edmonson
    Windows Azure Web Sites has added a new pricing tier that will solve the #1 blocker for the web development community. The shared tier now supports custom domain names mapped to shared-instance web sites. This post will outline the plan changes and elaborate on how the new pricing model makes Windows Azure Web Sites an even richer option for web development shops of all sizes. Free Shared Reserved # of Sites 10 100 100 Egress 165MB/Day 5GB/Month Included 5GB/Month Included Storage 1GB 1GB 10GB Throttling CPU/Memory/Egress CPU/Memory Unlimited Price Free $.02/hr per site, per instance $.08/hr per core Setting the Stage In June, we released the first public preview of Windows Azure Web Sites, which gave web developers a great platform on which to get web sites running using their web development framework of choice. PHP, Node.js, classic ASP, and ASP.NET developers can all utilize the Windows Azure platform to create and launch their web sites. Likewise, these developers have a series of data storage options using Windows Azure SQL Databases, MySQL, or Windows Azure Storage. The Windows Azure Web Sites free offer enabled startups to get their site up and running on Windows Azure with a minimal investment, and with multiple deployment and continuous integration features such as Git, Team Foundation Services, FTP, and Web Deploy.  The response to the Windows Azure Web Sites offer has been overwhelmingly positive. Since the addition of the service on June 12th, tens of thousands of web sites have been deployed to Windows Azure and the volume of adoption is increasing every week. Preview Feedback In spite of the growth and success of the product, the community has had questions about features lacking in the free preview offer. The main question web developers asked regarding Windows Azure Web Sites relates to the lack of the free offer’s support for domain name mapping. During the preview launch period, customer feedback made it obvious that the lack of domain name mapping support was an area of concern. We’re happy to announce that this #1 request has been delivered as a feature of the new shared plan. New Shared Tier Portal Features In the screen shot below, the “Scale” tab in the portal shows the new tiers – Free, Shared, and Reserved – and gives the user the ability to quickly move any of their free web sites into the shared tier. With a single mouse-click, the user can move their site into the shared tier. Once a site has been moved into the shared tier, a new Manage Domains button appears in the bottom action bar of the Windows Azure Portal giving site owners the ability to manage their domain names for a shared site. This button brings up the domain-management dialog, which can be used to enter in a specific domain name that will be mapped to the Windows Azure Web Site. Shared Tier Benefits Startups and large web agencies will both benefit from this plan change. Here are a few examples of scenarios which fit the new pricing model: Startups no longer have to select the reserved plan to map domain names to their sites. Instead, they can use the free option to develop their sites and choose on a site-by-site basis which sites they elect to move into the shared plan, paying only for the sites that are finished and ready to be domain-mapped Agencies who manage dozens of sites will realize a lower cost of ownership over the long term by moving their sites into reserved mode. Once multi-site companies reach a certain price point in the shared tier, it is much more cost-effective to move sites to a reserved tier.  Long-term, it’s easy to see how the new Windows Azure Web Sites shared pricing tier makes Windows Azure Web Sites it a great choice for both startups and agency customers, as it enables rapid growth and upgrades while keeping the cost to a minimum. Large agencies will be able to have all of their sites in their own instances, and startups will have the capability to scale up to multiple-shared instances for minimal cost and eventually move to reserved instances without worrying about the need to incur continually additional costs. Customers can feel confident they have the power of the Microsoft Windows Azure brand and our world-class support, at prices competitive in the market. Plus, in addition to realizing the cost savings, they’ll have the whole family of Windows Azure features available. Continuous Deployment from GitHub and CodePlex Along with this new announcement are two other exciting new features. I’m proud to announce that web developers can now publish their web sites directly from CodePlex or GitHub.com repositories. Once connections are established between these services and your web sites, Windows Azure will automatically be notified every time a check-in occurs. This will then trigger Windows Azure to pull the source and compile/deploy the new version of your app to your web site automatically. Walk-through videos on how to perform these functions are below: Publishing to an Azure Web Site from CodePlex Publishing to an Azure Web Site from GitHub.com These changes, as well as the enhancements to the reserved plan model, make Windows Azure Web Sites a truly competitive hosting option. It’s never been easier or cheaper for a web developer to get up and running. Check out the free Windows Azure web site offering and see for yourself. Stay tuned to my twitter feed for Windows Azure announcements, updates, and links: @clinted

  • Selecting the (right?) technology and environment

    - by Tor
    We are two developers on the edge of starting new web product development. We are both fans of lean start-up approach and would like to practice continuous deployment. Here comes the dilemma - we are both coming from a C# / Windows background and we need to decide between: Stick to .NET and Windows, we will not waste time on learning new technologies and put all our effort in the development. Switch to Ruby on Rails and Linux which has a good reputation of fast ramp up and vast open source support. The negative side is that we will need to put a lot of effort in learning Ruby, Rails and Linux... What would you do? What other considerations should we take?

  • Scheduling Swingworker threads

    - by Simonw
    Hi, I have a 2 processes to perform in my swing application, one to fill a list, and one to do operations on each element on the list. I've just moved the 2 processes into Swingworker threads to stop the GUI locking up while the tasks are performed, and because I will need to do this set of operations to several lists, so concurrency wouldn't be a bad idea in the first place. However, when I just ran fillList.execute();doStuffToList.execute(); the doStuffToList thread to ran on the empty list (duh...). How do I tell the second process to wait until the first one is done? I suppose I could just nest the second process at the end of the first one, but i dunno, it seems like bad practice.
