  • Cannot implicitly convert type System.Collection.Generic.IEnumberable

    - by Cen
    I'm receiving this error in my Linq statement --- Cannot implicitly convert type 'System.Collections.Generic.IEnumerable' to 'hcgames.ObjectClasses.ShoppingCart.ShoppingCartCartAddon'. An explicit conversion exists (are you missing a cast?) From this query ShoppingCartItems items = Cart.GetAllItems(); ShoppingCartCartAddons addons = Cart.GetAllAddons(); var stuff = from x in items select new ShoppingCartItem() { ProductID = x.ProductID, Quantity = x.Quantity, Name = x.Name, Price = x.Price, Weight = x.Weight, Addons = (from y in addons where y.ShoppingCartItemID == x.ID select y) }; I can not figure out how to cast this properly. Any suggestions? Thanks for your help!

  • Play youtube video in full screen ?

    - by Madhup
    Hi all, First of all sorry, If somebody finds this question is repeated (haven't found any by myself). I am developing for an iPad application and trying to play youtube videos using this code: NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, youTubeUrl, 142.0, 129.5]; [wbView loadHTMLString:html baseURL:nil]; The code works fine when used in an iphone application (i.e. you touch on the webview and it starts playing the youtube video in fullscreen.) But when used in the iPad, on clicking the web view it starts playing the video in the web view itself and shows options to go to full screen, while I want to start the playback in the full screen from the beginning, like it does in the iPhone. Anybody having some ideas or people who have done it before please help. Thanks, Madhup

  • Synchronising scripts / db / files from dev system to web server

    - by Spoonface
    I work as a freelance web dev, and up until now have been ftping my scripts / databases / static files to my web server manually, but I'm finding that is too error prone. So I'm looking for an app to automate uploading new and updated scripts / files / databases / etc. I know a lot of independent devs use WinSCP or Unison, but I don't think those apps can synch databases. Does anyone have any other suggestions? It doesn't need to be anything overly feature rich as I'm not working within a team or across multiple operating systems or anything like that. I can purchase any reasonably priced license if necesary. My work is primarily for PHP / MySQL / Apache on a Windows system, and then uploaded to a Linux / Apache server. thanks for your time!

  • System::IDisposable woes

    - by shadeMe
    public ref class ScriptEditor : public Form { public: typedef map<UInt32, ScriptEditor^> AlMap; static AlMap AllocationMap; Form^ EditorForm; RichTextBox^ EditorBox; StatusBar^ EditorStatusBar; StatusBarPanel^ StatusBarLineNo; void Destroy() { EditorForm->Close(); } ScriptEditor(unsigned int PosX, unsigned int PosY); }; The above code throws an Error C2039: '{dtor}' : is not a member of 'System::IDisposable'. I'm quite lost after having looked into articles that explain how the CLR manages memory. Any advice on getting rid of it would be appreciated. My first dabble in C+++/CLI isn't going too well.

  • Best approach to design a service oriented system

    - by Gustavo Paulillo
    Thinking about service orientation, our team are involved on new application designs. We consist in a group of 4 developers and a manager (that knows something about programming and distributed systems). Each one, having own opinion on service design. It consists in a distributed system: a user interface (web app) accessing the services in a dedicated server (inside the firewall), to obtain the business logic operations. So we got 2 main approachs that I list above : Modular services Having many modules, each one consisting of a service (WCF). Example: namespaces SystemX.DebtService, SystemX.CreditService, SystemX.SimulatorService Unique service All the business logic is centralized in a unique service. Example: SystemX.OperationService. The web app calls the same service for all operations. In your opinion, whats the best? Or having another approach is better for this scenario?

  • Compile time float packing/punning

    - by detly
    I'm writing C for the PIC32MX, compiled with Microchip's PIC32 C compiler (based on GCC 3.4). My problem is this: I have some reprogrammable numeric data that is stored either on EEPROM or in the program flash of the chip. This means that when I want to store a float, I have to do some type punning: typedef union { int intval; float floatval; } IntFloat; unsigned int float_as_int(float fval) { IntFloat intf; intf.floatval = fval; return intf.intval; } // Stores an int of data in whatever storage we're using void StoreInt(unsigned int data, unsigned int address); void StoreFPVal(float data, unsigned int address) { StoreInt(float_as_int(data), address); } I also include default values as an array of compile time constants. For (unsigned) integer values this is trivial, I just use the integer literal. For floats, though, I have to use this Python snippet to convert them to their word representation to include them in the array: import struct hex(struct.unpack("I", struct.pack("f", float_value))[0]) ...and so my array of defaults has these indecipherable values like: const unsigned int DEFAULTS[] = { 0x00000001, // Some default integer value, 1 0x3C83126F, // Some default float value, 0.005 } (These actually take the form of X macro constructs, but that doesn't make a difference here.) Commenting is nice, but is there a better way? It's be great to be able to do something like: const unsigned int DEFAULTS[] = { 0x00000001, // Some default integer value, 1 COMPILE_TIME_CONVERT(0.005), // Some default float value, 0.005 } ...but I'm completely at a loss, and I don't even know if such a thing is possible. Notes Obviously "no, it isn't possible" is an acceptable answer if true. I'm not overly concerned about portability, so implementation defined behaviour is fine, undefined behaviour is not (I have the IDB appendix sitting in front of me). As fas as I'm aware, this needs to be a compile time conversion, since DEFAULTS is in the global scope. Please correct me if I'm wrong about this.

  • How can I find file system concurrency issues ?

    - by krosenvold
    I have an application running on Linux, and I find myself wanting windows (!). The problem is that every 1000 times or so I run into concurrency problems that are consistent with concurrent reading/writing of files. I am fairly sure that this behavior would be prohibited by file locking under Windows, but I don't have any sufficiently fast windows box to check. There is simply too much file access (too much data) to expect strace to work reliably - the sheer volume of output is likely to change the problem too. It also happens on different files every time. Ideally I would like to change/reconfigure the linux file system to be more restrictive (as in fail-fast) wrt concurrent access. Are there any tools/settings I can use to achieve this ?

  • FileInputStream for a generic file System

    - by Akhil
    I have a file that contains java serialized objects like "Vector". I have stored this file over Hadoop Distributed File System(HDFS). Now I intend to read this file (using method readObject) in one of the map task. I suppose FileInputStream in = new FileInputStream("hdfs/path/to/file"); wont' work as the file is stored over HDFS. So I thought of using org.apache.hadoop.fs.FileSystem class. But Unfortunately it does not have any method that returns FileInputStream. All it has is a method that returns FSDataInputStream but I want a inputstream that can read serialized java objects like vector from a file rather than just primitive data types that FSDataInputStream would do. Please help!

  • Database layout tagging system

    - by Kurresmack
    I am creating a web site for a customer and they want to be able to create articles. My idea is to tag them so I am going to implement the system. What is the best design, both from an architectural and a perfomance perspective: 1. To have table with all tags and then have a one to many relationship table that links a tag like this: articles table with ID tags table with ID one to many table with columns Article.ID and Tags.ID 2. To have one table with articles and one with tags for articles like this: articles table with ID tags table with Article.ID and tag text Thanks in advance!

  • Implementing Communication Protocols on CC2420 motes powered by TinyOS

    - by stanigator
    I would like to load TinyOS on CC2420 radio motes to operate on certain communication protocols (e.g. epidemic routing, probabilistic routing, etc.). However, I have no prior experience in programming motes to perform the protocols I want. I'm just wondering about the most applicable resources for reference and how difficult (if not impossible) was implementing such mentioned protocols. It would be great to hear from you. Thanks in advance!

  • Sign Up/Login system for multi-domain/multi-server

    - by David
    I'm thinking about a good solution for implementing a sign up/login system that works across different domains and servers. A working example is Olx (you can register in one domain, and your login will work in the rest of domains). The scenario is that every domain (one per country) has its own database. And there will be 2 servers (for example), each one will have the 50% of the domains (and so the 50% of databases). What would you suggest to start with? Database: MySQL 5.1 Server-side language: PHP 5.3 (I will be using Symfony 1.4, so if someone has some suggestion for this framework, it will be interesting too, although it is optional)

  • Use a light font weight with Sifr

    - by Smickie
    Hi, With sifr, how do I make a font use the light weight version. I have... var gillsans = { src: '/resources/swf/gillsans.swf' }; sIFR.activate(gillsans); sIFR.replace(gillsans, { selector: 'h1', css: '.sIFR-root { background-color: #FFFFFF; color: #000000; text-transform:uppercase; }' }); which is displaying regular Gill Sans, the light version has been exported with the swf (said so in the export report), but how do I get it to display in sifr?

  • System.Web.HttpException in asp.net mvc 2 on images and javascript files

    - by Rippo
    Hi I am getting the following errors reported by ELMAH on my asp.net mvc 2 site for javascript files, images etc. System.Web.HttpException: The remote host closed the connection I have done some research and it appears that the user/bot is clicking a link on the site before the page has fully loaded. Now this error never occurs on a controller action but always on a file that is on disk. e.g. /Content/CmsImages/logo.png /Content/CmsImages/MemberImages/Photo-001605.jpg /Content/jquery.tickertype.js So this means that all static files are being routed through the mvc pipeline. What options do I have?

  • Compiler error when casting to function pointer

    - by detly
    I'm writing a bootloader for the PIC32MX, using HiTech's PICC32 compiler (similar to C90). At some point I need to jump to the real main routine, so somewhere in the bootloader I have void (*user_main) (void); user_main = (void (*) (void)) 0x9D003000; user_main(); (Note that in the actual code, the function signature is typedef'd and the address is a macro.) I would rather calculate that (virtual) address from the physical address, and have something like: void (*user_main) (void); user_main = (void (*) (void)) (0x1D003000 | 0x80000000); user_main(); ...but when I try that I get a compiler error: Error #474: ; 0: no psect specified for function variable/argument allocation Have I tripped over some vagarity of C syntax here? This error doesn't reference any particular line, but if I comment out the user_main() call, it goes away. (This might be the compiler removing a redundant code branch, but the HiTech PICC32 isn't particularly smart in Lite mode, so maybe not.)

  • What XSS/CSRF attacks (if any) to be aware of when allowing video embeds?

    - by fireeyedboy
    I've been assigned a project for a website where users will be allowed to upload video's (using a YouTube API) but more importantly (for me) they will also be allowed to submit video embed codes (from numerous video sites, YouTube, Vimeo, etc. etc.). Having no experience with allowing users to embed video: How can I best protect against cross site scripting and/or cross site request forgery attacks specifically for video embedding? What are some of the common pitfalls to watch for? At a minumum I would think to strip all tags except <object> and <embed>. But I have a feeling this will not be enough, will it? If it is of importance, the environment will be: PHP/Zend Framework MySQL Bonuspoints: Is there a common minimum golden rule/code template for video embed codes that are valid across all video sites that I could use to filter the input?
