  • Software tools for allowing end users to reprogram interfaces

    - by iceman
    What would be the examples of commercial software products (specially web-services) which allow the end user to reprogram their user-interface? I mean end users who do not know programming and they are allowed to add more functionality. One way of doing it is allowing XML gadgets like iGoogle does. What are the other approaches and also the technologies enabling them? This would be a futuristic application like collaborative software development for users.

  • What's your all-time creativity problem?

    - by furtelwart
    Sometimes, you stumble with programming. Sometimes, it's a lack of creativity, sometimes, you need a new solution. But there are a lot of situations, you stick in, every time they occur. For myself, it's when I have to create the interface between model and viewer. I designed my data structure very well and drew a GUI prototype, but the missing link won't be written. What are your personal barricades in developing projects?

    What is the best method of performing an scp transfer via the Java programming language? It seems I may be able to perform this via JSSE, JSch or the bouncy castle java libraries. None of these solutions seem to have an easy answer.

  • What was your most useful/inspiring computer science course?

    - by MPelletier
    I'm currently taking one course per semester, remotely, in a short 5 year program. My aim is to get better at my trade (programming and analysis, not surprisingly). However, I find that I'm not inspired by my choice of classes for next semester. Maybe I'm being too judgmental. I'd like to know what positive experience was gained from a course in particular. Have ou had a course that turned out to be an idea catalyst?

  • How to reuse layouts in WPF

    - by Ingó Vals
    I'm trying to create a application that will be tabbed where each tab will have a button area and a view area. Now each tab will essentially have the same layout just different things in the layout and I wanted to be able to reuse the same layout so that I won't have to change at many places ( it's just not good programming ). Can I accomplish this using resources or perhaps Styles. Please supply a light code example if possible.

  • Render public html's for dynamic banners in Rails ?

    - by benoror
    Hi, I would like to render specific HTML snippets for displaying banners, because each banner has a different nature (some images, some flash, etc). Every banner file is under app/public/banners/. I tried many ways, like: render :file => "/banners/somebanner.html" But it can't locate the file, because rails looks under app/views. Any Ideas ? Thanks! Missing template banners/somebanner.html in view path app/views

  • iPhone Safari localStorage does not persist after device reboot

    - by Tom
    Hi, I write a simple iPhone web app using HTML5's localStorage. Tests on a 2G device show the data does not persist after an iPhone reboot. This is a test code: <html> <head> <meta name="viewport" content="height=device-height, width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /> </head> <body> <script> alert("1:" + localStorage.getItem("test")); localStorage.setItem("test", "123"); alert("2:" + localStorage.getItem("test")); </script> </body> As far as I understand the data should persist even after a device reboot. Can anyone shed some light on this behavior? Thanks! Tom.

  • What are the most common SQL anti-patterns?

    - by le dorfier
    All of us who work with relational databases have learned (or are learning) that SQL is different. Eliciting the desired results, and doing so efficiently, involves a tedious process partly characterized by learning unfamiliar paradigms, and finding out that some of our most familiar programming patterns don't work here. What are the most common antipatterns you've seen (or your self committed), whether generic or product-specific, whether in SQL statements directly, or in the ways applications build and apply them?

  • "Go To Definition" in Visual Studio only brings up the Metadata

    - by pfunk
    I am working in a Web Project in Visual Studio 2008. When I hit F12 (or right-click and select Go To Definition) Visual Studio is consistently going to the Meta data file instead of going to the source. Some Points: All the source code is C#, there is no VB.Net All the projects are in the same solution Yes, everything is a project reference (checked and double-checked) I have tried the Clean/Rebuild Solution approach (even to the point of clearing out the Temp directory, Temporary ASP.NET Files directory, etc). Has anyone else seen this behavior and/or know how to fix it?

  • Getting XML parse error in coldfusion. Can the packet returned be validated?

    - by jeff
    Getting an error on occasion on a specific CF page. Offending code listed below. Very odd because when I rebooted CF it went away. Can the XML be checked via XMLValidate to prevent this from happening? Is this some sort of CF bug since the error disappeared after reboot of CF? I have a feeling that the error will resurface at some point. An error occured while Parsing an XML document. The element type "meta" must be terminated by the matching end-tag "". <cfhttp method="get" url="http://bs.mysite.com/webservice/rec/get.sbs?customerId=345S4BE8x&itemId=#product_id#&number=20&ruleId=#product.location_tab_accessories#"> <cfset result = xmlParse(cfhttp.FileContent)> <cfset recs = xmlSearch(result, "/result/thsite/site/itemId")>
