  • Kohana 3 jQuery/AJAX request not working

    - by dscher
    I am trying to post some data to a controller in Kohana 3 using the jQuery AJAX method. I seem to have an issue with the data not getting to where I want it to be. I want the data to go to the /application/classes/controller/stock.php file where the file will process the data. I can't seem to figure this one out. Hopefully someone can help. My jQuery ajax call is: $.ajax({ type: 'POST', url: 'add_stock', data: { 'links': 'link_array' } }); 'add_stock' is the name of the action within the controller. I didn't know what else to try. I've also tried '.' and './' hoping that would be right but it's not. In Firebug, although it says the request was 200 OK, I see that the "RESPONSE" is "Failed to load source for: http://localhost/ddm/v2/stocks/add_stock" and my script in my controller which grabs the data isn't working. Here is that code in case it helps: $links = $_POST['links']; $link_obj = Jelly::factory('link') ->set('stock', $stock->id) ->set('links', $links); $link_obj->save(); I think that the problem is that I'm giving the ajax call the ROUTE and not the actual page it needs to deliver the POST data to. I just can't figure it out here. Any help?

  • 3 tier application pattern suggestion

    - by Maxim Gershkovich
    I have attempted to make my first 3 tier application. In the process I have run into one problem I am yet to find an optimal solution for. Basically all my objects use an IFillable interface which forces the implementation of a sub as follows Public Sub Fill(ByVal Datareader As Data.IDataReader) Implements IFillable.Fill This sub then expects the Ids from the datareader will be identical to the properties of the object as such. Me.m_StockID = Datareader.GetGuid(Datareader.GetOrdinal("StockID")) In the end I end up with a datalayer that looks something like this. Public Shared Function GetStockByID(ByVal ConnectionString As String, ByVal StockID As Guid) As Stock Dim res As New Stock Using sqlConn As New SqlConnection(ConnectionString) sqlConn.Open() res.Fill(StockDataLayer.GetStockByIDQuery(sqlConn, StockID)) End Using Return res End Function Mostly this pattern seems to make sense. However my problem is, lets say I want to implement a property for Stock called StockBarcodeList. Under the above mentioned pattern any way I implement this property I will need to pass a connectionstring to it which obviously breaks my attempt at layer separation. Does anyone have any suggestions on how I might be able to solve this problem or am I going about this the completely wrong way? Does anyone have any suggestions on how I might improve my implementation? Please note however I am deliberately trying to avoid using the dataset in any form.

  • Updating MS Access Database from Datagridview

    - by Peter Roche
    I am trying to update an ms access database from a datagridview. The datagridview is populated on a button click and the database is updated when any cell is modified. The code example I have been using populates on form load and uses the cellendedit event. private OleDbConnection connection = null; private OleDbDataAdapter dataadapter = null; private DataSet ds = null; private void Form2_Load(object sender, EventArgs e) { string connetionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='C:\\Users\\Peter\\Documents\\Visual Studio 2010\\Projects\\StockIT\\StockIT\\bin\\Debug\\StockManagement.accdb';Persist Security Info=True;Jet OLEDB:Database Password="; string sql = "SELECT * FROM StockCount"; connection = new OleDbConnection(connetionString); dataadapter = new OleDbDataAdapter(sql, connection); ds = new DataSet(); connection.Open(); dataadapter.Fill(ds, "Stock"); connection.Close(); dataGridView1.DataSource = ds; dataGridView1.DataMember = "Stock"; } private void addUpadateButton_Click(object sender, EventArgs e) { } private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e) { try { dataadapter.Update(ds,"Stock"); } catch (Exception exceptionObj) { MessageBox.Show(exceptionObj.Message.ToString()); } } The error I receive is Update requires a valid UpdateCommand when passed DataRow collection with modified rows. I'm not sure where this command needs to go and how to reference the cell to update the value in the database.

  • How do I rewrite a for loop with a shared dependency using actors

    - by Thomas Rynne
    We have some code which needs to run faster. Its already profiled so we would like to make use of multiple threads. Usually I would setup an in memory queue, and have a number of threads taking jobs of the queue and calculating the results. For the shared data I would use a ConcurrentHashMap or similar. I don't really want to go down that route again. From what I have read using actors will result in cleaner code and if I use akka migrating to more than 1 jvm should be easier. Is that true? However, I don't know how to think in actors so I am not sure where to start. To give a better idea of the problem here is some sample code: case class Trade(price:Double, volume:Int, stock:String) { def value(priceCalculator:PriceCalculator) = (priceCalculator.priceFor(stock)-> price)*volume } class PriceCalculator { def priceFor(stock:String) = { Thread.sleep(20)//a slow operation which can be cached 50.0 } } object ValueTrades { def valueAll(trades:List[Trade], priceCalculator:PriceCalculator):List[(Trade,Double)] = { trades.map { trade => (trade,trade.value(priceCalculator)) } } def main(args:Array[String]) { val trades = List( Trade(30.5, 10, "Foo"), Trade(30.5, 20, "Foo") //usually much longer ) val priceCalculator = new PriceCalculator val values = valueAll(trades, priceCalculator) } } I'd appreciate it if someone with experience using actors could suggest how this would map on to actors.

  • PHP mobile browser detection?

    - by TreyK
    I'm in need of a way to detect mobile browsers server-side. I'd like a way that requires me to do little to set up and little to maintain, yet still provide me with accurate detection of (at the VERY least) Android, Mobile Safari and Blackberry browsers, along with alternatives like Opera. I'd like to have at least the majority of the mobile market covered, and I'd really prefer virtually all of the market if it doesn't take much.

    - by Helper Method
    Is there still a market for C system programmers? I love Java and some of the newer JVM languages but at the same time I really enjoy low-level system programming under Unix, using C and the GNU toolchain (it makes you feel elitist ;-)). Now I wonder a) is there still a market for C system programmers and b) how much do you earn compared to an app programmer c) is it that much fun in a large scale project?

  • Implementing In App purchases in Android?

    - by hgpc
    It looks like Android won't natively support in-app purchases for a while, and when it does there might be a huge user base with devices that don't support them. What's the best way to implement iPhone-like (additional content or services) in-app purchases in Android using the Android Market if possible? The solution should consider in particular: For all kinds of in-app purchases: Android Market's 24-hour cancellation policy For consumables/non-consumables: storage of additional content (ie: use precious application memory to avoid piracy, or use SD card to avoid bloating application memory) Thanks!

  • Microsoft Declares the Future of ASP.NET is Web API

    - by sbwalker
    Sitting on a plane on my way home from Tech Ed 2012 in Orlando, I thought it would be a good time to jot down some key takeaways from this year’s conference. Some of these items I have known since the Microsoft MVP Summit which occurred in Redmond in late February ( but due to NDA restrictions I could not share them with the developer community at large ) and some of them are a result of insightful conversations with a wide variety of industry insiders and Microsoft employees at the conference. First, let’s travel back in time 4 years to the Microsoft MVP Summit in 2008. Microsoft was facing some heat from market newcomer Ruby on Rails and responded with a new web development framework of its own, ASP.NET MVC. At the Summit they estimated that MVC would only be applicable for ~10% of all new web development projects. Based on that prediction I questioned why they were investing such considerable resources for such a relative edge case, but my guess is that they felt it was an important edge case at the time as some of the more vocal .NET evangelists as well as some very high profile start-ups ( ie. Twitter ) had publicly announced their intent to use Rails. Microsoft made a lot of noise about MVC. In fact, they focused so much of their messaging and marketing hype around MVC that it appeared that WebForms was essentially dead. Yes, it may have been true that Microsoft continued to invest in WebForms, but from an outside perspective it really appeared that MVC was the only framework getting any real attention. As a result, MVC started to gain market share. An inside source at Microsoft told me that MVC usage has grown at a rate of about 5% per year and now sits at ~30%. Essentially by focusing so much marketing effort on MVC, Microsoft actually created a larger market demand for it.  This is because in the Microsoft ecosystem there is somewhat of a bandwagon mentality amongst developers. If Microsoft spends a lot of time talking about a specific technology, developers get the perception that it must be really important. So rather than choosing the right tool for the job, they often choose the tool with the most marketing hype and then try to sell it to the customer. In 2010, I blogged about the fact that MVC did not make any business sense for the DotNetNuke platform. This was because our ecosystem relied on third party extensions which were dependent on the WebForms model. If we migrated the core to MVC it would mean that all of the third party extensions would no longer be compatible, which would be an irresponsible business decision for us to make at the expense of our users and customers. However, this did not stop the debate from continuing to occur in our ecosystem. Clearly some developers had drunk Microsoft’s Kool-Aid about MVC and were of the mindset, to paraphrase an old Scottish saying, “If its not MVC, it’s crap”. Now, this is a rather ignorant position to take as most of the benefits of MVC can be achieved in WebForms with solid architecture and responsible coding practices. Clean separation of concerns, unit testing, and direct control over page output are all possible in the WebForms model – it just requires diligence and discipline. So over the past few years some horror stories have begun to bubble to the surface of software development projects focused on ground-up rewrites of web applications for the sole purpose of migrating from WebForms to MVC. These large scale rewrites were typically initiated by engineering teams with only a single argument driving the business decision, that Microsoft was promoting MVC as “the future”. These ill-fated rewrites offered no benefit to end users or customers and in fact resulted in a less stable, less scalable and more complicated systems – basically taking one step forward and two full steps back. A case in point is the announcement earlier this week that a popular open source .NET CMS provider has decided to pull the plug on their new MVC product which has been under active development for more than 18 months and revert back to WebForms. The availability of multiple server-side development models has deeply fragmented the Microsoft developer community. Some folks like to compare it to the age-old VB vs. C# language debate. However, the VB vs. C# language debate was ultimately more of a religious war because at least the two dominant programming languages were compatible with one another and could be used interchangeably. The issue with WebForms vs. MVC is much more challenging. This is because the messaging from Microsoft has positioned the two solutions as being incompatible with one another and as a result web developers feel like they are forced to choose one path or another. Yes, it is true that it has always been technically possible to use WebForms and MVC in the same project, but the tooling support has always made this feel “dirty”. The fragmentation has also made it difficult to attract newcomers as the perceived barrier to entry for learning ASP.NET has become higher. As a result many new software developers entering the market are gravitating to environments where the development model seems more simple and intuitive ( ie. PHP or Ruby ). At the same time that the Web Platform team was busy promoting ASP.NET MVC, the Microsoft Office team has been promoting Sharepoint as a platform for building internal enterprise web applications. Sharepoint has great penetration in the enterprise and over time has been enhanced with improved extensibility capabilities for software developers. But, like many other mature enterprise ASP.NET web applications, it is built on the WebForms development model. Similar to DotNetNuke, Sharepoint leverages a rich third party ecosystem for both generic web controls and more specialized WebParts – both of which rely on WebForms. So basically this resulted in a situation where the Web Platform group had headed off in one direction and the Office team had gone in another direction, and the end customer was stuck in the middle trying to figure out what to do with their existing investments in Microsoft technology. It really emphasized the perception that the left hand was not speaking to the right hand, as strategically speaking there did not seem to be any high level plan from Microsoft to ensure consistency and continuity across the different product lines. With the introduction of ASP.NET MVC, it also made some of the third party control vendors scratch their heads, and wonder what the heck Microsoft was thinking. The original value proposition of ASP.NET over Classic ASP was the ability for web developers to emulate the highly productive desktop development model by using abstract components for creating rich, interactive web interfaces. Web control vendors like Telerik, Infragistics, DevExpress, and ComponentArt had all built sizable businesses offering powerful user interface components to WebForms developers. And even after MVC was introduced these vendors continued to improve their products, offering greater productivity and a superior user experience via AJAX to what was possible in MVC. And since many developers were comfortable and satisfied with these third party solutions, the demand remained strong and the third party web control market continued to prosper despite the availability of MVC. While all of this was going on in the Microsoft ecosystem, there has also been a fundamental shift in the general software development industry. Driven by the explosion of Internet-enabled devices, the focus has now centered on service-oriented architecture (SOA). Service-oriented architecture is all about defining a public API for your product that any client can consume; whether it’s a native application running on a smart phone or tablet, a web browser taking advantage of HTML5 and Javascript, or a rich desktop application running on a PC. REST-based services which utilize the less verbose characteristics of JSON as a transport mechanism, have become the preferred approach over older, more bloated SOAP-based techniques. SOA also has the benefit of producing a cross-platform API, as every major technology stack is able to interact with standard REST-based web services. And for web applications, more and more developers are turning to robust Javascript libraries like JQuery and Knockout for browser-based client-side development techniques for calling web services and rendering content to end users. In fact, traditional server-side page rendering has largely fallen out of favor, resulting in decreased demand for server-side frameworks like Ruby on Rails, WebForms, and (gasp) MVC. In response to these new industry trends, Microsoft did what it always does – it immediately poured some resources into developing a solution which will ensure they remain relevant and competitive in the web space. This work culminated in a new framework which was branded as Web API. It is convention-based and designed to embrace native HTTP standards without copious layers of abstraction. This framework is designed to be the ultimate replacement for both the REST aspects of WCF and ASP.NET MVC Web Services. And since it was developed out of band with a dependency only on ASP.NET 4.0, it means that it can be used immediately in a variety of production scenarios. So at Tech Ed 2012 it was made abundantly clear in numerous sessions that Microsoft views Web API as the “Future of ASP.NET”. In fact, one Microsoft PM even went as far as to say that if we look 3-4 years into the future, that all ASP.NET web applications will be developed using the Web API approach. This is a fairly bold prediction and clearly telegraphs where Microsoft plans to allocate its resources going forward. Currently Web API is being delivered as part of the MVC4 package, but this is only temporary for the sake of convenience. It also sounds like there are still internal discussions going on in terms of how to brand the various aspects of ASP.NET going forward – perhaps the moniker of “ASP.NET Web Stack” coined a couple years ago by Scott Hanselman and utilized as part of the open source release of ASP.NET bits on Codeplex a few months back will eventually stick. Web API is being positioned as the unification of ASP.NET – the glue that is able to pull this fragmented mess back together again. The  “One ASP.NET” strategy will promote the use of all frameworks - WebForms, MVC, and Web API, even within the same web project. Basically the message is utilize the appropriate aspects of each framework to solve your business problems. Instead of navigating developers to a fork in the road, the plan is to educate them that “hybrid” applications are a great strategy for delivering solutions to customers. In addition, the service-oriented approach coupled with client-side development promoted by Web API can effectively be used in both WebForms and MVC applications. So this means it is also relevant to application platforms like DotNetNuke and Sharepoint, which means that it starts to create a unified development strategy across all ASP.NET product lines once again. And so what about MVC? There have actually been rumors floated that MVC has reached a stage of maturity where, similar to WebForms, it will be treated more as a maintenance product line going forward ( MVC4 may in fact be the last significant iteration of this framework ). This may sound alarming to some folks who have recently adopted MVC but it really shouldn’t, as both WebForms and MVC will continue to play a vital role in delivering solutions to customers. They will just not be the primary area where Microsoft is spending the majority of its R&D resources. That distinction will obviously go to Web API. And when the question comes up of why not enhance MVC to make it work with Web API, you must take a step back and look at this from the higher level to see that it really makes no sense. MVC is a server-side page compositing framework; whereas, Web API promotes client-side page compositing with a heavy focus on web services. In order to make MVC work well with Web API, would require a complete rewrite of MVC and at the end of the day, there would be no upgrade path for existing MVC applications. So it really does not make much business sense. So what does this have to do with DotNetNuke? Well, around 8-12 months ago we recognized the software industry trends towards web services and client-side development. We decided to utilize a “hybrid” model which would provide compatibility for existing modules while at the same time provide a bridge for developers who wanted to utilize more modern web techniques. Customers who like the productivity and familiarity of WebForms can continue to build custom modules using the traditional approach. However, in DotNetNuke 6.2 we also introduced a new Service Framework which is actually built on top of MVC2 ( we chose to leverage MVC because it had the most intuitive, light-weight REST implementation in the .NET stack ). The Services Framework allowed us to build some rich interactive features in DotNetNuke 6.2, including the Messaging and Notification Center and Activity Feed. But based on where we know Microsoft is heading, it makes sense for the next major version of DotNetNuke ( which is expected to be released in Q4 2012 ) to migrate from MVC2 to Web API. This will likely result in some breaking changes in the Services Framework but we feel it is the best approach for ensuring the platform remains highly modern and relevant. The fact that our development strategy is perfectly aligned with the “One ASP.NET” strategy from Microsoft means that our customers and developer community can be confident in their current and future investments in the DotNetNuke platform.

  • Laptop battery: is voltage really important to respect?

    - by Marc-Andre R.
    I got an Acer Aspire 5100 and I just bought a new battery (after the stock battery just died yesterday). But I saw something after buying and I'm wondering whether it's really important or not. My stock battery was a 6-cell 4000mah 11.1v and the new battery is an 8-cell 4800mah 14.8v . I know that 8-cell and 4800mah is okay, but what about the 14.8v instead of 11.1v? The battery description says it's compatible with my laptop model (AS5100, model BL51), but the voltage difference makes me wonder. Will the laptop only take what it needs? Or will it be getting 14.8v straight in the brain? I know that my wall plug claims to output 19v, so logically I'm thinking a higher voltage battery shouldn't be a problem. Am I correct in thinking this? Thanks in advance for your answers!

  • Automatically keeping two excel data tables in-sync (w/out VBA)

    - by Neil
    I'm putting together a workbook for tracking a stock portfolio. The primary sheet contains a table with the list of the transactions. From this I would like to create an overview table on another sheet with only one row per unique stock symbol that includes things like cost basis, returns, etc. The problem is that nothing I've tried updates the overview table correctly when rows are added to the transaction table. The closest I've got is something like the following: http://www.get-digital-help.com/2009/04/14/create-a-unique-alphabetically-sorted-list-extracted-from-a-column/ However, this requires applying that formula to every cell in the primary column of the overview sheet. And even then the range of the table isn't extended down to include new rows as they become valid. Essentially I'm looking for a way that auto-adds rows to a table and copies the formula based on a different table changing without using VBA. Trivial example data Sheet1 Symbol Type Shares Price F Buy 100 12 MSFT Buy 100 25 MSFT Sell 50 28 F Buy 100 16 Sheet2 Symbol Quantity F 200 MSFT 50

  • Win 7 BSOD stucks at dumping

    - by AFO
    Recently Ive been getting frequent bsods, which always gets stuck at dumping without finishing it, with most of them showing no error messages. This never happened before i upgraded to new rams, but 2 passes of memtest86 turned out fine. Tried reinstalling windows, problem still there. Tried initiating a manual crash, and that did create a successful dump. The SSD win 7 is on doesn't seem to have any problems, crystaldisk says its healthy. Varied the cpu multiplier between stock and +500Mhz, crashed regardless. Left voltage control to auto. Im fairly sure its a hardware problem, just cant pinpoint which specific part(s). The specs- Windows 7 x64 (1 day old) 955 x4 BE c3 (running at stock) (3.5 years old) GA-970A-D3 (1.5 years old) Gigabyte 6950, unlocked to 6970 (still at 6950 speeds) (<3 years old) 2x4GB 1600 CL9 HyperX Blu (running at 11-11-11, default motherboard setting) (<1 month old) Plextor M5s (around 5 months)
