  • ASP.NET MVC based CMS - dynamic generation of form helpers

    - by user252160
    I am working on an ASP.NET MVC based CMS that presents a rather extreme case. The system must allow the user to add custom content types based on different fields, and for every field, one can add options and validations. The thing is that everything is stored in a complex DB and extracted at runtime using LINQ. I am pretty fresh with ASPNET MVC so the following dilemma came to mind How should I make the content creation view so that form helpers are not predefined int he view code but are loaded based on the type of the field ? Do I have to create a factory class that checks the value of the type property of the field, and then returns a helper based on that or there's a better way to do it. This one seems pretty rigid to me , because anytime I make a change in the Fieldtypes table, I will have to make sure to create a check for that new type too.

  • Interop: HmacSHA1 in Java and dotNet

    - by wilth
    Hello, In an app we are calculating a SHA1Hmac in java using the following: SecretKey key = new SecretKeySpec(secret, "HmacSHA1"); Mac m = Mac.getInstance("HmacSHA1"); m.init(secret); byte[] hmac = m.doFinal(data); And later, the hmac is verified in C# - on a SmartCard - using: HMACSHA1 hmacSha = new HMACSHA1(secret); hmacSha.Initialize(); byte[] hmac = hmacSha.ComputeHash(data); However, the result is not the same. Did I overlook something important? The inputs seem to be the same. Here some sample inputs: Data: 546573746461746131323341fa3c35 Key: 6d795472616e73616374696f6e536563726574 Result Java: 37dbde318b5e88acbd846775e38b08fe4d15dac6 Result C#: dd626b0be6ae78b09352a0e39f4d0e30bb3f8eb9 I wouldn't mind to implement my own hmacsha1 on both platforms, but using what already exists.... Thanks!

  • Async Socket Listener on separate thread - VB.net

    - by TheHockeyGeek
    I am trying to use the code from Microsoft for an Async Socket connection. It appears the listener runs in the main thread locking the GUI. I am new at both socket connections and multi-threading all at the same time. Having a hard time getting my mind wrapped around this all at once. The code used is at http://msdn.microsoft.com/en-us/library/fx6588te.aspx Using this example, how can I move the listener to its own thread? Public Shared Sub Main() ' Data buffer for incoming data. Dim bytes() As Byte = New [Byte](1023) {} ' Establish the local endpoint for the socket. Dim ipHostInfo As IPHostEntry = Dns.GetHostEntry(Dns.GetHostName()) Dim ipAddress As IPAddress = ipHostInfo.AddressList(1) Dim localEndPoint As New IPEndPoint(ipAddress, 11000) ' Create a TCP/IP socket. Dim listener As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) ' Bind the socket to the local endpoint and listen for incoming connections. listener.Bind(localEndPoint) listener.Listen(100)

  • Good Front end for PostgreSQL on Windows or Mac

    - by anjanb
    I'm considering using postgreSQL 8.4x db on windows/Mac for development and linux for production. wondering what front-end tools are out there that are comparable to Toad (for Oracle) ? PostgreSQL comes with PgAdminIII. It's OK but I feel there might be something better than that. I prefer free or open source but if something is NOT too expensive(we are a NON-PROFIT), would not mind evaluating. minimal tools that I want 1) connection manager 2) Nice SQL Editor 3) Explain Plan 4) help with SQL embedding into various languages. 5) E-R diagrams would be good but this would not be a killer feature for me. Anything work for you guys ? Will be using java 6 to build the application(s) if that is relevant at all. Thank you,

  • A public web API: What do developers prefer to consume?

    - by spender
    We've got a bunch of data that we'd like to expose to the world hosted on an asp-net.mvc website. I'd like to ensure that we deliver it using technology that is easy for end developers to implement and not tied to any particular platform, rather than using technology that is unpopular/incompatible with developers. The kind of requests we expect are mainly to retrieve search results (not many parameters), but down the like we'd like to be able to provide catalogue lookups and the like, which may be more complex. Bearing this in mind, what is the preferred means of doing this?

  • Managing Team Development on Shared Website

    - by stjowa
    I need to know the best way to manage team web-development on a shared server (hostgator). I have done some individual web development on a shared server in the past, and I have always setup SVN through SSH to have a pretty-nice development workflow (version control, quick-commits, work though eclipse/subclipse, etc). However, I also know that with that setup, I had to make some pretty-sophisticated post-commit hooks to export the repository to /public_html; and, therefore, making the repository code testable. This seems like a tedious and error-prone setup for an entire team. I would like to be able to: Easily test the latest code in the repository. Somewhat easily move the code in the repository to production. Use an IDE like eclipse/subclipse to easily work with the repository. With this in mind, does anyone know of a good version-control/repository setup for developing a website with a team of about 4-5 people? Thanks a lot.

  • Is it wrong to get feedback from Stack Overflow on a live system architecture?

    - by hal10001
    I am the technical director at a startup, and I will eventually be tasked with implementing a "real" system architecture when we hire more programmers. Right now our clients are small enough, and it is just me, so documented deployments, source control, unit tests and quality assurance servers are non-existent. Eventually I will need to devise a work-flow and architecture patterns for the majority of the work we will do (e-commerce). If I posted an architecture diagram, and asked for feedback, would that be a misuse of the Stack Overflow system? I don't want to get into that battle of "hey, don't ask us to do your job for you", but the reality is that any programmer who eventually moves into this realm will have to figure it out with feedback from other developers. HighScalability.com is what comes to mind when I think about this sorta thing in terms of the knowledge I need. So if this is not the right kind of forum for that, then any book recommendations or white papers you can recommend would be appreciated.

  • Can MYSQL filter by date if date is stored as text? ex "02/10/1984"

    - by Roeland
    Hello! I am trying to modify an app for a client which has already a database of over 1000 items. The dates are stored as text in the database with the format "02/10/1984". The system allows you to add and remove fields to the catalog dynamically and it also allows the advanced search to have specific fields be allowed. The problem is that it wasn't designed with dates in mind, so when I set a field as a date, and try to search by a range the query is trying to do a AND (cfv0.value = 01/02/2004 AND cfv0.value <= 05/03/2008) . I can make it so the date range passed is a numeric time value. Is there a way that when sending the query, it takes the text fields (with the date) and converts it to numeric time value so at that point I am basically just comparing numbers which would work fine. I do not have the option to change all the current date to numeric value due to the way the dynamic fields are set up. Thanks guys!

  • .NET AxWebBrowser can't open page "Navigation to the webpage was canceled" error

    - by Erdnod
    Oh, I am stuck again on this quiet annoying problem. I am trying to do a little automated browsing using the axWebBrowser component and it worked before. Now all of a sudden I get the following message when I try to browse to a page. Navigation to the webpage was canceled What you can try: Refresh the page. I totally disabled my firewall, ran VS2008 in Administrator mode, I even installed IE8 all to no avail. By the way IE8 doesn't work either. I don't know if the problem is related but all I get when I put a URL into IE8 is this message. Internet Explorer cannot display the webpage I don't so much mind that, I just really need to get my visual studio axWebBrowser working.

  • Why do we use HTTP and not remote invocations?

    - by BrokenClockwork
    Hey, first of all this is a conceptional question and I do not know if StackOverflow is the appropriate place - so my apologies if I am wrong. Nowadays the web is not only used for passing raw informations. Many and especially complex web applications are in use. These web application seem to be so complex that it seems irrational to use the HTTP protocol, which is based on so simple data exchange, plus it is stateless. Would it not be more convincing to use remote invocations for this web applications? The big advantage to my mind is a unified GUI by using HTML. But there are applications, which have no need for a graphical interfaces and then it comes to a point where the HTTP protocol is really cumbersome.

  • Visual Studio bug ~ can anyone duplicate?

    - by drachenstern
    In Visual Studio 2010 Pro (Version 10.0.30319.1 RTMRel), I noticed tonight that for some reason I kept getting a wider window for quick find, but thought I was losing my mind. So I exited, restarted, etc to verify. Here's my repro steps Open existing project (I don't think it matters which one) Press ctrlf and give it something to search for (?) Press enter Press ctrlf Press enter goto 4 Can you reproduce a slowly expanding quick find window? Do I have some sort of wacky bugged out system? I'ld obviously like to submit a bug report to MS if this is indeed a viable repro.

  • Anyone knows of a good addressbook implementation?

    - by Tsahi Levent-Levi
    I am looking to add an address book to one of my programs. For that purpose, I want to have something that is flexible and customizable to the point of allowing me to hook up additional metadata to contacts in it from third parties. I don't mind paying for a solution as long as I get something that is usable for me. My requirements: Optimized to run on embedded devices Preferably in source code form Ability to add my own fields to contacts over those the address book provides out of the box Ability to plugin "stuff" to it to enhance it without changing its base code too much Has a C or C++ interface

  • How to make a 3D UI for an application ?

    - by wacky_coder
    I'm building an application and I'd like its User Interface to be 3D, most probably a cylinder. The user would see the cylinder[Horizontally laid] and the cylinder's curved surface would have the buttons and any other controls that need to be placed. The cylinder needs to rotate and later, I'd like to add some other effects to the cylinder too. Someone told me that such a UI can be modelled using Maya or Blender and exported to openGL and then I could use C/C++ (with Qt) to carry out the actions. How can this be done?? Is there any other way to build the UI and do all the other things that I need ?? I really need some help because I have the UI in mind, but no idea on how to implement it. Thanks

  • How do I stop image spam from being uploaded to my (future) site?

    - by Pete Lacey
    I have in mind an idea for a generally accessible site that needs to allow images to be uploaded. But I'm stymied on how to prevent image spam: porn, ads in image form, etc. Assumptions: I'm assuming that the spammers are clever, even human. I'm skeptical of the efficacy of image analysis software. I do not have the resources to approve all uploads manually. I am willing to spend money on the solution -- within reason. This site will be location-aware, if that helps. How does Flickr do it or imgur? Or do they?

  • Need a list of all countries in the world, with a longitude and latitude coordinate

    - by ptrn
    I need a list of all the countries in the world, with one lat/long coordinate for the country. I had a look at GeoNames, but all I can seem to find are lists that have the countries as well as cities in the same list. I guess I can just parse it and filter out the countries, but I was hoping to avoid that. Basically, what I need; Country name - Lat/long coordinate (some sort of center of the country) It doesn't need to say anything about continent, but I wouldn't mind if it did. _L

  • How to correctly calculate address spaces?

    - by user337308
    Below is an example of a question given on my last test in a Computer Engineering course. Anyone mind explaining to me how to get the start/end addresses of each? I have listed the correct answers at the bottom... The MSP430F2410 device has an address space of 64 KB (the basic MSP430 architecture). Fill in the table below if we know the following. The first 16 bytes of the address space (starting at the address 0x0000) is reserved for special function registers (IE1, IE2, IFG1, IFG2, etc.), the next 240 bytes is reserved for 8-bit peripheral devices, and the next 256 bytes is reserved for 16-bit peripheral devices. The RAM memory capacity is 2 Kbytes and it starts at the address 0x1100. At the top of the address space is 56KB of flash memory reserved for code and interrupt vector table. What Start Address End Address Special Function Registers (16 bytes) 0x0000 0x000F 8-bit peripheral devices (240 bytes) 0x0010 0x00FF 16-bit peripheral devices (256 bytes) 0x0100 0x01FF RAM memory (2 Kbytes) 0x1100 0x18FF Flash Memory (56 Kbytes) 0x2000 0xFFFF

  • Setting up a web developer lab for learning purposes

    - by Saleh Al-Abbas
    I'm not a developer by profession. Therefore, I'm not exposed to real world technical problems that face professional developers. I read/heard about web farms, integration between different systems, load balancing ... etc. Therefore, I was wondering if there are ways for the individual developer to create an environment that simulates real world situations with minimal number of machines like: web farms & caching simulating many users accessing your website (Pressure tests?) Performance load balancing anything you think I should consider. By the way, I have a server machine and 1 PC. and I don't mind investing in tools and software. PS. I'm using Microsoft technologies for development but I hope this is not a limiting factor. Thanks

  • Test For CSS3 Radial Gradient Vendor Syntax

    - by Scott Christopherson
    I'm having an issue where I'm trying to update the background gradient of an element with JavaScript based on values I specify. I tried this route: elem.style.backgroundImage = '-webkit-gradient(radial, '+x+' '+y+', 0, '+x+' '+y+', 800, from(#ccc), to(#333)), -moz-radial-gradient('+x+'px '+y+'px, circle cover, #ccc 0, #333 100%)'; Since Webkit and Gecko have two different syntaxes for CSS3 gradients, I need to specify both. However, the above code doesn't work. It works if I only have just the Gecko syntax or just the Webkit syntax, not both. I think you can check for CSS gradient support, but my question is, is there a way to check which syntax needs to be used without browser sniffing? Keep in mind that I need to set my gradients this way since the x and y coordinates of the gradient change dynamically. Hope this makes sense, thanks.

  • correct approach to store in database

    - by John
    I'm developing an online website (using Django and Mysql). I have a Tests table and User table. I have 50 tests within the table and each user completes them at their own pace. How do I store the status of the tests in my DB? One idea that came to my mind is to create an additional column in User table. That column containing testid's separated by comma or any other delimiter. userid | username | testscompleted 1 john 1, 5, 34 2 tom 1, 10, 23, 25 Another idea was to create a seperate table to store userid and testid. So, I'll have only 2 columns but thousands of rows (no of tests * no of users) and they will always continue to increase. userid | testid 1 1 1 5 2 1 1 34 2 10

Now i have a wcf client and a wcf service . what should be the shortest way forward ?should i use soap auth header to send the user ID and password and how should the token be transported ( in which field ? http or soap's ?) . P.S: of course i shall enable ssl later.

  • Hiding members in a C struct

    - by Marlon
    I've been reading about OOP in C but I never liked how you can't have private data members like you can in C++. But then it came to my mind that you could create 2 structures. One is defined in the header file and the other is defined in the source file. // ========================================= // in somestruct.h typedef struct { int _public_member; } SomeStruct; // ========================================= // in somestruct.cpp #include "somestruct.h" typedef struct { int _public_member; int _private_member; } SomeStructSource; SomeStruct *SomeStruct_Create() { SomeStructSource *p = (SomeStructSource *)malloc(sizeof(SomeStructSource)); p->_private_member = 0xWHATEVER; return (SomeStruct *)p; } From here you can just cast one structure to the other. Is this considered bad practice? Or is it done often? (I think this is done with a lot of the structures when using the Win32 API, but you guys are the experts let me know!)

  • Why is Read-Modify-Write necessary for registers on embedded systems?

    - by Adam Shiemke
    I was reading http://embeddedgurus.com/embedded-bridge/2010/03/different-bit-types-in-different-registers/, which said: With read/write bits, firmware sets and clears bits when needed. It typically first reads the register, modifies the desired bit, then writes the modified value back out and I have run into that consrtuct while maintaining some production code coded by old salt embedded guys here. I don't understand why this is necessary. When I want to set/clear a bit, I always just or/nand with a bitmask. To my mind, this solves any threadsafe problems, since I assume setting (either by assignment or oring with a mask) a register only takes one cycle. On the other hand, if you first read the register, then modify, then write, an interrupt happening between the read and write may result in writing an old value to the register. So why read-modify-write? Is it still necessary?

  • Alternative design for a synonyms table?

    - by Majid
    I am working on an app which is to suggest alternative words/phrases for input text. I have doubts about what might be a good design for the synonyms table. Design considerations: number of synonyms is variable, i.e. football has one synonym (soccer), but in particular has two (particularly, specifically) if football is a synonym to soccer, the relation exists in the opposite direction as well. our goal is to query a word and find its synonyms we want to keep the table small and make adding new words easy What comes to my mind is a two column design with col a = word and col b = delimited list of synonyms Is there any better alternative? What about using two tables, one for words and the other for relations?

  • Use of Icons from a GPL'd program

    - by clartaq
    There is a GPL'd program that has some nice icons I would like to use in a project of my own. I would like to release my project under a more liberal license like Apache or BSD. After reading the GPL V3 license (a few times), I can't figure out how it applies to resources like icons. Can I use them at all? If so, must I release my new project under GPL instead of some other license? Of course, I plan to contact the original author and ask them what they had in mind and honor that intent. But what are the legal requirements for use of graphical resources from GPL'd software?
