  • UpdateAllWindows() from within a worker thread?

    - by Harvey
    I have a worker thread in a class that is owned by a ChildView. (I intend to move this to the Doc eventually.) When the worker thread completes a task I want all the views to be updated. How can I make a call to tell the Doc to issue an UpdateAllViews()? Or is there a better approach? Thank you.

  • Why is my Extension Method not showing up in my test class?

    - by Robert Harvey
    I created an extension method called HasContentPermission on the System.Security.Principal.IIdentity interface: namespace System.Security.Principal { public static bool HasContentPermission (this IIdentity itentity, int contentID) { // I do stuff here return result; } } And I call it like this: bool hasPermission = User.Identity.HasPermission(contentID); Works like a charm. Now I want to unit test it. To do that, all I really need to do is call the extension method directly, so: using System.Security.Principal; namespace MyUnitTests { [TestMethod] public void HasContentPermission_PermissionRecordExists_ReturnsTrue() { IIdentity identity; bool result = identity.HasContentPermission(... But HasContentPermission won't intellisense. I tried creating a stub class that inherits from IIdentity, but that didn't work either. Why? Or am I going about this the wrong way?

  • Paste or Drop, copy data and release source?

    - by Harvey
    I have an MFC DocView SDI App that receives data from either the clipboard or drag and drop. The data is in either CF_HDROP or CF_TEXT format. I have a COleDropTarget derived CMyDropTarget member m_dropTarget of my CMainFrame class. I have two member functions of CMyDropTarget; OnDrop(...) and OnPaste() which each call another member function PostData(pDataObject). I want to get a copy of the pDataObject from either CF_... format and PostMessage to my CmainFrame which will call a member of my Doc class. What is a simple way of getting a copy of the global data to pass with the PostMessage() so that I can get the drop source released before I get around to processing the global data? NOTE that they are always treated as a copy of the source data, so there is no need for the source to delete anything when the operation is done. Or perhaps a better way of asking the question is: How can I release the Drop source before processing the global data? Can I pass the HGLOBAL via PostMessage and still release the source without making a copy of it?

  • Possible Performance Considerations using Linq to SQL Repositories

    - by Robert Harvey
    I have an ASP.NET MVC application that uses Linq to SQL repositories for all interactions with the database. To deal with data security, I do trimming to filter data to only those items to which the user has access. This occurs in several places: Data in list views Links in a menu bar A treeview on the left hand side containing links to content Role-based security A special security attribute, inheriting from AuthorizeAttribute, that implements content-based authorization on every controller method. Each of these places instantiates a repository, which opens a Linq to Sql DataContext and accesses the database. So, by my count, each request for a page access opens at least six separate Linq to SQL DataContexts. Should I be concerned about this from a performance perspective, and if so, what can be done to mitigate it?

  • Managing multiple customer databases in ASP.NET MVC application

    - by Robert Harvey
    I am building an application that requires separate SQL Server databases for each customer. To achieve this, I need to be able to create a new customer folder, put a copy of a prototype database in the folder, change the name of the database, and attach it as a new "database instance" to SQL Server. The prototype database contains all of the required table, field and index definitions, but no data records. I will be using SMO to manage attaching, detaching and renaming the databases. In the process of creating the prototype database, I tried attaching a copy of the database (companion .MDF, .LDF pair) to SQL Server, using Sql Server Management Studio, and discovered that SSMS expects the database to reside in c:\program files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabaseName.MDF Is this a "feature" of SQL Server? Is there a way to manage individual databases in separate directories? Or am I going to have to put all of the customer databases in the same directory? (I was hoping for a little better control than this). NOTE: I am currently using SQL Server Express, but for testing purposes only. The production database will be SQL Server 2008, Enterprise version. So "User Instances" are not an option.

  • Creating a standalone ASP.NET MVC application for Windows XP

    - by Robert Harvey
    Is there a way to create an installable (ideally XCopy installable) version of an ASP.NET MVC application that will run in a standalone fashion on a Windows XP machine? I don't mind installing SQL Server Express for this purpose, so I guess the question boils down to this: Can the Cassini web server that comes with Visual Studio 2008 be bundled with the application? Or are there other options? NOTE: The installation is for demo purposes only, so there are no licensing problems. Also, I am suggesting Cassini because I don't know of a way to install IIS7 on Windows XP. I can't do major hackage on the registry to get this to work.

  • What's the right tool for this job in Google Spreadsheets?

    - by Daniel Harvey
    Is it possible to nest simple programs within a Google doc spreadsheet, similar to how you would w/Basic in Excel? Or alternatively a simple = syntax using regex, if there is a way to do that in google docs? I want to take a list of multiple names(name1, name2, name3) in a single cell from across multiple identical sheets and transpose them to another sheet within the same spreadsheet, check for duplicates and ignore capitals, etc. Is there a way to do this?

  • How do you manage the namespaces of your extension methods?

    - by Robert Harvey
    Do you use a global, catchall namespace for all of your extension methods, or do you put the extension methods in the same namespace as the class(es) they extend? Or do you use some other method, like an application or library-specific namespace? EDIT: I ask because I have a need to extend System.Security.Principal.IIdentity, and putting the extension method in the System.Security.Principal namespace seems to make sense, but I've never seen it done this way.

  • Are today's young programmers getting wrapped around the axle with patterns and practices?

    - by Robert Harvey
    Recently I have noticed a number of questions on SO that look something like this: I am writing a small program to keep a list of the songs that I keep on my ipod. I'm thinking about writing it as a 3-tier MVC Ruby on Rails web application with TDD, DDD and IOC, using a factory pattern to create the classes and a singleton to store my application settings. Do you think I'm taking the right approach? Do you think that we're handing novice programmers a very sharp knife and telling them, "Don't cut yourself with this"? NOTE: Despite the humorous tone, this is a serious (and programming-related) question.

  • Modifying text files and executing programs with command line parameters in c# or c++ on Linux

    - by Robert Harvey
    I have a need to create a utility in Suze Linux. The utility will make modifications to some text files, and then use the information in those text files to program a device in the computer using a different executable which accepts command line parameters. I am fluent in c#, but have never worked with Linux. Should I take the time to learn Gnu C++ to do this, or install Mono? How would I execute the programming utility and pass it command line parameters?

  • OpenID PAM module

    - by Harvey Kwok
    I am looking for a PAM module that can use OpenID to do the authentication. My idea is that I want to logon my Linux box using my gmail account and password. I found there is a open source project in Google Code which seems to be doing the things I want but I don't see any code available for download. I saw there are so many examples or implementations but they are all about web apps. Is there any non-web based OpenID applications in the world? Is it technically possible to make a non-web based OpenID application? I naively think that it should be possible. I can emulate whatever packets the browser send out to the OpenID provider and get back the result. As long as my Linux box is connected to the Internet, I should be able to use my OpenID to login. Appreciate any comments, suggestions or pointers on how to make an OpenID PAM module. Thanks!

  • How do I pass Url Parameters on a POST?

    - by Robert Harvey
    I have a controller method with the following signature: [AcceptVerbs(HttpVerbs.Post)] public ActionResult UpdateValues(int id, MyViewModel[] array) { } The id is normally picked up as part of the Url on other GET controller methods (I have a working route that does this) I am successfully passing the array1 from the form in my view to the controller method, but how do I also put the id onto my Url so that when the user clicks the Submit button, the controller method will pick up the ID?

  • accessing variable sheet ranges within Google spreadsheet?

    - by Daniel Harvey
    I've been trying to keep this little project entirely within Google docs, but I may have hit a wall. The spreadsheet is being used as a way for multiple users to record individual events with a Template they duplicate. I want to be able to compile a list of names of those attended onto a "report" sheet from all of the unique sheets, which should be after a certain sheet index [3] to [infinite]. Is this sort of variable sheet range possible in Google spreadsheets or do I need to go to the API to get this accomplished?

  • Are there any C++ style and/or standard example files available?

    - by Harvey
    While there are lots of questions about coding style, beautifying, and enforcement, I haven't found any example C++ files that are used as a quick reference for style. The file should be one or two pages long and exemplify a given coding standard/style. For example, the Google C++ Style Guide is a great reference, but I think a one to two page piece of code written in their style pinned to a wall would be more useful in day-to-day use. Do any of these already exist?

  • Right-Time Retail Part 2

    - by David Dorf
    This is part two of the three-part series. Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Right-Time Integration Of course these real-time enabling technologies are only as good as the systems that utilize them, and it only takes one bottleneck to slow everyone else down. What good is an immediate stock-out notification if the supply chain can’t react until tomorrow? Since being formed in 2006, Oracle Retail has been not only adding more integrations between systems, but also modernizing integrations for appropriate speed. Notice I tossed in the word “appropriate.” Not everything needs to be real-time – again, we’re talking about Right-Time Retail. The speed of data capture, analysis, and execution must be synchronized or you’re wasting effort. Unfortunately, there isn’t an enterprise-wide dial that you can crank-up for your estate. You’ll need to improve things piecemeal, with people and processes as limiting factors while choosing the appropriate types of integrations. There are three integration styles we see in the retail industry. First is batch. I know, the word “batch” just sounds slow, but this pattern is less about velocity and more about volume. When there are large amounts of data to be moved, you’ll want to use batch processes. Our technology of choice here is Oracle Data Integrator (ODI), which provides a fast version of Extract-Transform-Load (ETL). Instead of the three-step process, the load and transform steps are combined to save time. ODI is a key technology for moving data into Retail Analytics where we can apply science. Performing analytics on each sale as it occurs doesn’t make any sense, so we batch up a statistically significant amount and submit all at once. The second style is fire-and-forget. For some types of data, we want the data to arrive ASAP but immediacy is not necessary. Speed is less important than guaranteed delivery, so we use message-oriented middleware available in both Weblogic and the Oracle database. For example, Point-of-Service transactions are queued for delivery to Central Office at corporate. If the network is offline, those transactions remain in the queue and will be delivered when the network returns. Transactions cannot be lost and they must be delivered in order. (Ever tried processing a return before the sale?) To enhance the standard queues, we offer the Retail Integration Bus (RIB) to help the management and monitoring of fire-and-forget messaging in the enterprise. The third style is request-response and is most commonly implemented as Web services. This is a synchronous message where the sender waits for a response. In this situation, the volume of data is small, guaranteed delivery is not necessary, but speed is very important. Examples include the website checking inventory, a price lookup, or processing a credit card authorization. The Oracle Service Bus (OSB) typically handles the routing of such messages, and we’ve enhanced its abilities with the Retail Service Backbone (RSB). To better understand these integration patterns and where they apply within the retail enterprise, we’re providing the Retail Reference Library (RRL) at no charge to Oracle Retail customers. The library is composed of a large number of industry business processes, including those necessary to support Commerce Anywhere, as well as detailed architectural diagrams. These diagrams allow implementers to understand the systems involved in integrations and the specific data payloads. Furthermore, with our upcoming release we’ll be providing a new tool called the Retail Integration Console (RIC) that allows IT to monitor and manage integrations from a single point. Using RIC, retailers can quickly discern where integration activity is occurring, volume statistics, average response times, and errors. The dashboards provide the ability to dive down into the architecture documentation to gather information all the way down to the specific payload. Retailers that want real-time integrations will also need real-time monitoring of those integrations to ensure service-level agreements are maintained. Part 3 looks at marketing.

  • Facebook likes reset after moving to HTTPS (URL manually set in script, though)

    - by aarondicks
    Hi fellow Facebook developers. I've got a question regarding the Facebook like button. We worked on a piece recently that embeds a number of social share buttons (please see the source code below or here on Harvey Water Softeners' website) When the piece was released, it was on HTTP, and received over 2k likes (the URL 'slug' hasn't changed at all). The site was recently migrated to permanent-on HTTPS, and the like data has been reset, and we've been left with 50 new, recent likes. If you see in the source code, the URL is set explicitly to like the HTTP version, which I believe to be correct. Can anyone help me work out what's happened here? Here's the HTML bit of the like button: <div class="fb-like" data-href="http://www.harveywatersofteners.co.uk/history-interior-design" data-layout="box_count" data-action="like" data-show-faces="false" data-share="false"></div> Thanks in advance Aaron

  • Get to Know a Candidate (6 of 25): Jill Stein&ndash;Green Party

    - by Brian Lanham
    DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Stein is a physician with degrees from Harvard College and Harvard Medical School.  She serves on the boards of Greater Boston Physicians for Social Responsibility and MassVoters for Fair Elections, and has been active with the Massachusetts Coalition for Healthy Communities Jill Stein advocates a "Green New Deal" in which renewable energy jobs would be created to address climate change and environmental issues with the objective of employing "every American willing and able to work". Citing the research of Dr. Phillip Harvey, Professor of Law & Economics at Rutgers University, as evidence of the successful economic effects of the 1930s' New Deal projects, Stein would fund the plan with a 30% reduction in the U.S. military budget, returning US troops home, and increasing taxes on areas such as capital gains, offshore tax havens and multimillion dollar real estate. Stein plans on impacting what she sees as a growing convergence of environmental crises in water, soil, fisheries and forests, through the creation of sustainable infrastructure based in clean renewable energy generation and sustainable communities principles such as increasing intra-city mass transit and inter-city railroads, creating 'complete streets' that safely encourage bike and pedestrian traffic and regional food systems based on sustainable organic agriculture The Green Party of the United States was founded in 1991 as a voluntary association of state green parties. With its founding, the Green Party of the United States became the primary national Green organization in the United States, eclipsing the Greens/Green Party USA, which emphasized non-electoral movement building. The Green Party of the United States of America emphasizes environmentalism, non-hierarchical participatory democracy, social justice, respect for diversity, peace and nonviolence. Their "Ten Key Values," which are described as non-authoritative guiding principles, are as follows: Grassroots democracy Social justice and equal opportunity Ecological wisdom Nonviolence Decentralization Community-based economics Feminism and gender equality Respect for diversity Personal and global responsibility Future focus and sustainability The Green Party does not accept donations from corporations. Thus, the party's platforms and rhetoric critique any corporate influence and control over government, media, and American society at large. Stein has access to 403 electoral votes and is a write-in candidate in GA, IN, and MS Learn more about Jill Stein and Green Party on Wikipedia.
