• ADF Business Components

  - by Arda Eralp

  ADF Business Components and JDeveloper simplify the development, delivery, and customization of business applications for the Java EE platform. With ADF Business Components, developers aren't required to write the application infrastructure code required by the typical Java EE application to: Connect to the database Retrieve data Lock database records Manage transactions   ADF Business Components addresses these tasks through its library of reusable software components and through the supporting design time facilities in JDeveloper. Most importantly, developers save time using ADF Business Components since the JDeveloper design time makes typical development tasks entirely declarative. In particular, JDeveloper supports declarative development with ADF Business Components to: Author and test business logic in components which automatically integrate with databases Reuse business logic through multiple SQL-based views of data, supporting different application tasks Access and update the views from browser, desktop, mobile, and web service clients Customize application functionality in layers without requiring modification of the delivered application The goal of ADF Business Components is to make the business services developer more productive.   ADF Business Components provides a foundation of Java classes that allow your business-tier application components to leverage the functionality provided in the following areas: Simplifying Data Access Design a data model for client displays, including only necessary data Include master-detail hierarchies of any complexity as part of the data model Implement end-user Query-by-Example data filtering without code Automatically coordinate data model changes with business services layer Automatically validate and save any changes to the database   Enforcing Business Domain Validation and Business Logic Declaratively enforce required fields, primary key uniqueness, data precision-scale, and foreign key references Easily capture and enforce both simple and complex business rules, programmatically or declaratively, with multilevel validation support Navigate relationships between business domain objects and enforce constraints related to compound components   Supporting Sophisticated UIs with Multipage Units of Work Automatically reflect changes made by business service application logic in the user interface Retrieve reference information from related tables, and automatically maintain the information when the user changes foreign-key values Simplify multistep web-based business transactions with automatic web-tier state management Handle images, video, sound, and documents without having to use code Synchronize pending data changes across multiple views of data Consistently apply prompts, tooltips, format masks, and error messages in any application Define custom metadata for any business components to support metadata-driven user interface or application functionality Add dynamic attributes at runtime to simplify per-row state management   Implementing High-Performance Service-Oriented Architecture Support highly functional web service interfaces for business integration without writing code Enforce best-practice interface-based programming style Simplify application security with automatic JAAS integration and audit maintenance "Write once, run anywhere": use the same business service as plain Java class, EJB session bean, or web service   Streamlining Application Customization Extend component functionality after delivery without modifying source code Globally substitute delivered components with extended ones without modifying the application   ADF Business Components implements the business service through the following set of cooperating components: Entity object An entity object represents a row in a database table and simplifies modifying its data by handling all data manipulation language (DML) operations for you. These are basically your 1 to 1 representation of a database table. Each table in the database will have 1 and only 1 EO. The EO contains the mapping between columns and attributes. EO's also contain the business logic and validation. These are you core data services. They are responsible for updating, inserting and deleting records. The Attributes tab displays the actual mapping between attributes and columns, the mapping has following fields: Name : contains the name of the attribute we expose in our data model. Type : defines the data type of the attribute in our application. Column : specifies the column to which we want to map the attribute with Column Type : contains the type of the column in the database   View object A view object represents a SQL query. You use the full power of the familiar SQL language to join, filter, sort, and aggregate data into exactly the shape required by the end-user task. The attributes in the View Objects are actually coming from the Entity Object. In the end the VO will generate a query but you basically build a VO by selecting which EO need to participate in the VO and which attributes of those EO you want to use. That's why you have the Entity Usage column so you can see the relation between VO and EO. In the query tab you can clearly see the query that will be generated for the VO. At this stage we don't need it and just use it for information purpose. In later stages we might use it. Application module An application module is the controller of your data layer. It is responsible for keeping hold of the transaction. It exposes the data model to the view layer. You expose the VO's through the Application Module. This is the abstraction of your data layer which you want to show to the outside word.It defines an updatable data model and top-level procedures and functions (called service methods) related to a logical unit of work related to an end-user task. While the base components handle all the common cases through built-in behavior, customization is always possible and the default behavior provided by the base components can be easily overridden or augmented. When you create EO's, a foreign key will be translated into an association in our model. It defines the type of relation and who is the master and child as well as how the visibility of the association looks like. A similar concept exists to identify relations between view objects. These are called view links. These are almost identical as association except that a view link is based upon attributes defined in the view object. It can also be based upon an association. Here's a short summary: Entity Objects: representations of tables Association: Relations between EO's. Representations of foreign keys View Objects: Logical model View Links: Relationships between view objects Application Model: interface to your application

• Windows Phone 8 Announcement

  - by Tim Murphy

  As if the Surface announcement on Monday wasn’t exciting enough, today Microsoft announce that Windows Phone 8 will be coming this fall.  That itself is great news, but the features coming were like confetti flying in all different directions.  Given this speed I couldn’t capture every feature they covered.  A summary of what I did capture is listed below starting with their eight main features. Common Core The first thing that they covered is that Windows Phone 8 will share a core OS with Windows 8.  It will also run natively on multiple cores.  They mentioned that they have run it on up to 64 cores to this point.  The phones as you might expect will at least start as dual core.  If you remember there were metrics saying that Windows Phone 7 performed operations faster on a single core than other platforms did with dual cores.  The metrics they showed here indicate that Windows Phone 8 runs faster on comparable dual core hardware than other platforms. New Screen Resolutions Screen resolution has never been an issue for me, but it has been a criticism of Windows Phone 7 in the media.  Windows Phone 8 will supports three screen resolutions: WVGA 800 x 480, WXGA 1280 x 768, and 720 1280x720.  Hopefully this makes pixel counters a little happier. MicroSD Support This was one of my pet peeves when I got my Samsung Focus. With Windows Phone 8 the operating system will support adding MicroSD cards after initial setup.  Of course this is dependent on the hardware company on implementing it, but I think we have seen that even feature phone manufacturers have not had a problem supporting this in the past. NFC NFC has been an anticipated feature for some time.  What Microsoft showed today included the fact that they didn’t just want it to be for the phone.  There is cross platform NFC functionality between Windows Phone 8 and Windows 8.  The demos , while possibly a bit fanciful, showed would could be achieved even in a retail environment.  We are getting closer and closer to a Minority Report world with these technologies. Wallet Windows Phone 8 isn’t the first platform to have a wallet concept.  What they have done to differentiate themselves is to make it sot that it is not dependent on a SIM type chip like other platforms.  They have also expanded the concept beyond just banks to other types of credits such as airline miles. Nokia Mapping People have been envious of the Lumia phones having the Nokia mapping software.  Now all Windows Phone 8 devices will use NavTeq data and will have the capability to run in an offline fashion.  This is a major step forward from the Bing “touch for the next turn” maps. IT Administration The lack of features for enterprise administration and deployment was a complaint even before the Windows Phone 7 was released.  With the Windows Phone 8 release such features as Bitlocker and Secure boot will be baked into the OS. We will also have the ability to privately sign and distribute applications. Changing Start Screen Joe Belfiore made a big deal about this aspect of the new release.  Users will have more color themes available to them and the live tiles will be highly customizable. You will have the ability to resize and organize the tiles in a more dynamic way.  This allows for less important tiles or ones with less information to be made smaller.  And There Is More So what other tidbits came out of the presentation?  Later this summer the API for WP8 will be available.  There will be developer events coming to a city near you.  Another announcement of interest to developers is the ability to write applications at a native code level.  This is a boon for game developers and those who need highly efficient applications. As a topper on the cake there was mention of in app payment. On the consumer side we also found out that all updates will be available over the air.  Along with this came the fact that Microsoft will support all devices with updates for at least 18 month and you will be able to subscribe for early updates.  Update coming for Windows Phone 7.5 customers to WP7.8.  The main enhancement will be the new live tile features.  The big bonus is that the update will bypass the carriers.  I would assume though that you will be brought up to date with all previous patches that your carrier may not have released. There is so much more, but that is enough for one post.  Needless to say, EXCITING! del.icio.us Tags: Windows Phone 8,WP8,Windows Phone 7,WP7,Announcements,Microsoft

• UIView with IrrlichtScene - iOS

  - by user1459024

  i have a UIViewController in a Storyboard and want to draw a IrrlichtScene in this View Controller. My Code: WWSViewController.h #import <UIKit/UIKit.h> @interface WWSViewController : UIViewController { IBOutlet UILabel *errorLabel; } @end WWSViewController.mm #import "WWSViewController.h" #include "../../ressources/irrlicht/include/irrlicht.h" using namespace irr; using namespace core; using namespace scene; using namespace video; using namespace io; using namespace gui; @interface WWSViewController () @end @implementation WWSViewController -(void)awakeFromNib { errorLabel = [[UILabel alloc] init]; errorLabel.text = @""; IrrlichtDevice *device = createDevice( video::EDT_OGLES1, dimension2d<u32>(640, 480), 16, false, false, false, 0); /* Set the caption of the window to some nice text.

Furthermore I'm getting this Error: Could not load sprite bank because the file does not exist: #DefaultFont How can i fix it ?

• Clouds, Clouds, Clouds Everywhere, Not a Drop of Rain!

  - by sxkumar

  At the recently concluded Oracle OpenWorld 2012, the center of discussion was clearly Cloud. Over the five action packed days, I got to meet a large number of customers and most of them had serious interest in all things cloud.  Public Cloud - particularly the Oracle Cloud - clearly got a lot of attention and interest. I think the use cases and the value proposition for public cloud is pretty straight forward. However, when it comes to private cloud, there were some interesting revelations.  Well, I shouldn’t really call them revelations since they are pretty consistent with what I have heard from customers at other conferences as well as during 1:1 interactions. While the interest in enterprise private cloud remains to be very high, only a handful of enterprises have truly embarked on a journey to create what the purists would call true private cloud - with capabilities such as self-service and chargeback/show back. For a large majority, today's reality is simply consolidation and virtualization - and they are quite far off from creating an agile, self-service and transparent IT infrastructure which is what the enterprise cloud is all about.  Even a handful of those who have actually implemented a close-to-real enterprise private cloud have taken an infrastructure centric approach and are seeing only limited business upside. Quite a few were frank enough to admit that chargeback and self-service isn’t something that they see an immediate need for.  This is in quite contrast to the picture being painted by all those surveys out there that show a large number of enterprises having already implemented an enterprise private cloud.  On the face of it, this seems quite contrary to the observations outlined above. So what exactly is the reality? Well, the reality is that there is undoubtedly a huge amount of interest among enterprises about transforming their legacy IT environment - which is often seen as too rigid, too fragmented, and ultimately too expensive - to something more agile, transparent and business-focused. At the same time however, there is a great deal of confusion among CIOs and architects about how to get there. This isn't very surprising given all the buzz and hype surrounding cloud computing. Every IT vendor claims to have the most unique solution and there isn't a single IT product out there that does not have a cloud angle to it. Add to this the chatter on the blogosphere, it will get even a sane mind spinning.  Consequently, most  enterprises are still struggling to fully understand the concept and value of enterprise private cloud.  Even among those who have chosen to move forward relatively early, quite a few have made their decisions more based on vendor influence/preferences rather than what their businesses actually need.  Clearly, there is a disconnect between the promise of the enterprise private cloud and the current adoption trends.  So what is the way forward?  I certainly do not claim to have all the answers. But here is a perspective that many cloud practitioners have found useful and thus worth sharing. To take a step back, the fundamental premise of the enterprise private cloud is IT transformation. It is the quest to create a more agile, transparent and efficient IT infrastructure that is driven more by business needs rather than constrained by operational and procedural inefficiencies. It is the new way of delivering and consuming IT services - where the IT organizations operate more like enablers of  strategic services rather than just being the gatekeepers of IT resources. In an enterprise private cloud environment, IT organizations are expected to empower the end users via self-service access/control and provide the business stakeholders a transparent view of how the resources are being used, what’s the cost of delivering a given service, how well are the customers being served, etc.  But the most important thing to note here is the enterprise private cloud is not just an IT project, rather it is a business initiative to create an IT setup that is more aligned with the needs of today's dynamic and highly competitive business environment. Surprised? You shouldn’t be. Just remember how the business users have been at the forefront of public cloud adoption within enterprises and private cloud is no exception.   Such a broad-based transformation makes cloud more than a technology initiative. It requires people (organizational) and process changes as well, and these changes are as critical as is the choice of right tools and technology. In my next blog,  I will share how essential it is for enterprise cloud technology to go hand-in hand with process re-engineering and organization changes to unlock true value of  enterprise cloud. I am sharing a short video from my session "Managing your private Cloud" at Oracle OpenWorld 2012. More videos from this session will be posted at the recently introduced Zero to Cloud resource page. Many other experts of Oracle enterprise private cloud solution will join me on this blog "Zero to Cloud"  and share best practices , deployment tips and information on how to plan, build, deploy, monitor, manage , meter and optimize the enterprise private cloud. We look forward to your feedback, suggestions and having an engaging conversion with you on this blog.

• Who could ask for more with LESS CSS? (Part 1 of 3&ndash;Features)

  - by ToStringTheory

  It wasn’t very long ago that I first began to get into CSS precompilers such as SASS (Syntactically Awesome Stylesheets) and LESS (The Dynamic Stylesheet Language) and I had been hooked on the idea since.  When I finally had a new project come up, I leapt at the opportunity to try out one of these languages. Introduction To be honest, I was hesitant at first to add either framework as I didn’t really know much more than what I had read on their homepages, and I didn’t like the idea of adding too much complexity to a project - I couldn’t guarantee I would be the only person to support it in the future. Thankfully, both of these languages just add things into CSS.  You don’t HAVE to know LESS or SASS to do anything, you can still do your old school CSS, and your output will be the same.  However, when you want to start doing more advanced things such as variables, mixins, and color functions, the functionality is all there for you to utilize. From what I had read, SASS has a few more features than LESS, which is why I initially tried to figure out how to incorporate it into a MVC 4 project. However, through my research, I couldn’t find a way to accomplish this without including some bit of the Ruby on Rails framework on the computer running it, and I hated the fact that I had to do that.  Besides SASS, there is little chance of me getting into the RoR framework, at least in the next couple years.  So in the end, I settled with using LESS. Features So, what can LESS (or SASS) do for you?  There are several reasons I have come to love it in the past few weeks. 1 – Constants Using LESS, you can finally declare a constant and use its value across an entire CSS file. The case that most people would be familiar with is colors.  Wanting to declare one or two color variables that comprise the theme of the site, and not have to retype out their specific hex code each time, but rather a variable name.  What’s great about this is that if you end up having to change it, you only have to change it in one place.  An important thing to note is that you aren’t limited to creating constants just for colors, but for strings and measurements as well. 2 – Inheritance This is a cool feature in my mind for simplicity and organization.  Both LESS and SASS allow you to place selectors within other selectors, and when it is compiled, the languages will break the rules out as necessary and keep the inheritance chain you created in the selectors. Example LESS Code: #header {   h1 {     font-size: 26px;     font-weight: bold;   }   p {     font-size: 12px;     a     {       text-decoration: none;       &:hover {         border-width: 1px       }     }   } } Example Compiled CSS: #header h1 {   font-size: 26px;   font-weight: bold; } #header p {   font-size: 12px; } #header p a {   text-decoration: none; } #header p a:hover {   border-width: 1px; } 3 - Mixins Mixins are where languages like this really shine.  The ability to mixin other definitions setup a parametric mixin.  There is really a lot of content in this area, so I would suggest looking at http://lesscss.org for more information.  One of the things I would suggest if you do begin to use LESS is to also grab the mixins.less file from the Twitter Bootstrap project.  This file already has a bunch of predefined mixins for things like border-radius with all of the browser specific prefixes.  This alone is of great use! 4 – Color Functions This is the last thing I wanted to point out as my final post in this series will be utilizing these functions in a more drawn out manner.  Both LESS and SASS provide functions for getting information from a color (R,G,B,H,S,L).  Using these, it is easy to define a primary color, and then darken or lighten it a little for your needs.  Example: Example LESS Code: @base-color: #111; @red:        #842210; #footer {   color: (@base-color + #003300);   border-left:  2px;   border-right: 2px;   border-color: desaturate(@red, 10%); } Example Compiled CSS: #footer {    color: #114411;    border-left:  2px;    border-right: 2px;    border-color: #7d2717; } I have found that these can be very useful and powerful when constructing a site theme. Conclusion I came across LESS and SASS when looking for the best way to implement some type of CSS variables for colors, because I hated having to do a Find and Replace in all of the files using the colors, and in some instances, you couldn’t just find/replace because of the color choices interfering with other colors (color to replace of #000, yet come colors existed like #0002bc).  So in many cases I would end up having to do a Find and manually check each one. In my next post, I am going to cover how I’ve come to set up these items and the structure for the items in the project, as well as the conventions that I have come to start using.  In the final post in the series, I will cover a neat little side project I built in LESS dealing with colors!

• Windows service - COM class factory error 80070583

  - by jawonlee

  I have a Windows service that periodically scrapes some web pages, using mshtml and HtmlAgilityPack. For this particular C# code snippet: HTMLDocumentClass doc = new HTMLDocumentClass(); doc.write(new object[] { responseFromServer }); doc.close(); I get this error: Retrieving the COM class factory for component with CLSID {25336920-03F9-11CF-8FD0-00AA00686F13} failed due to the following error: 80070583. I tracked down the CLSID in the registry, and it turned out to be mshtml.dll. I also noticed that the version I actually have is version 7.0.6000.17023, and the registry version is listed as Version=7.0.3300.0. The error code 80070583 means "Class does not exist"; interestingly, I've also gotten an error from the same program with error code 80070582, or "Class already exists". What does it all mean? Edit: Since there are no answers, I ended up working around the problem, by ditching MSHTML and using HTML Agility Pack to parse HTML. How do I close this question?

• Google.com and clients1.google.com/generate_204

  - by David Murdoch

  I was looking into google.com's Net activity in firebug just because I was curious and noticed a request was returning "204 No Content." It turns out that a 204 No Content "is primarily intended to allow input for actions to take place without causing a change to the user agent's active document view, although any new or updated metainformation SHOULD be applied to the document currently in the user agent's active view." Whatever. I've looked into the JS source code and saw that "generate_204" is requested like this: (new Image).src="http://clients1.google.com/generate_204" No variable declaration/assignment at all. My first idea is that it was being used to track if Javascript is enabled. But the "(new Image).src='...'" call is called from a dynamically loaded external JS file anyway, so that would be pointless. Anyone have any ideas as to what the point could be? UPDATE "/generate_204" appears to be available on many google services/servers (e.g., maps.google.com/generate_204, maps.gstatic.com/generate_204, etc...). You can take advantage of this by pre-fetching the generate_204 pages for each google-owned service your web app may use. Like This: window.onload = function(){ var two_o_fours = [ // google maps domain ... "http://maps.google.com/generate_204", // google maps images domains ... "http://mt0.google.com/generate_204", "http://mt1.google.com/generate_204", "http://mt2.google.com/generate_204", "http://mt3.google.com/generate_204", // you can add your own 204 page for your subdomains too! "http://sub.domain.com/generate_204" ]; for(var i = 0, l = two_o_fours.length; i < l; ++i){ (new Image).src = two_o_fours[i]; } };

• Mixing AJAX requests with Flash scope objects not working

  - by AlanObject

  I have a JSF page that displays a table from an object called TableQuery that supports stateful pagination, sorting, etc. The bean that accesses the object is a RequestScoped object, and it attempts to preserve the TableQuery by storing it the flash map. The accessor method looks like this: public TableQuery<SysLog> getQuery() { if (query != null) return query; Flash flash = FacesContext.getCurrentInstance(). getExternalContext().getFlash(); query = (TableQuery) flash.get("Query"); if (query != null) System.out.println("TableSysLog.getQuery() Got query from flash!"); if (query == null) { query = slc.getNewTableQuery(); System.out.println("TableSysLog.getQuery() Created new query"); } flash.put("Query", query); return query; } The Links to go between pages are implemented with *p:commandLInk*s. I use Primefaces command link in AJAX mode so just the link gets processed when it is clicked. The action listener looks like this: public void doNextPage(ActionEvent evt) { getQuery().doNextPage(); } When it doesn't work I get the error message: WARNING: JSF1095: The response was already committed by the time we tried to set the outgoing cookie for the flash. Any values stored to the flash will not be available on the next request. I found this thread when looking up this problem. When I turned of HTTP chunking as the article suggests, the error message went away but the problem remained. Does anyone know what is going on and how this might be fixed?

• Cannot convert lambda expression to type 'string' because it is not a delegate type

  - by RememberME

  I have the following code written by another developer on 2 pages of my site. This used to work just fine, but now is giving the error "Cannot convert lambda expression to type 'string' because it is not a delegate type" on the Delete line with Ajax.ThemeRollerActionLink. I don't go into this section of the site often, and we recently upgraded from MVC 1.0 to 2.0. I'm guessing that's probably when it stopped working. I've looked up this error and the recommended fix seems to be add using System.Linq However, the page already has <%@ Import Namespace="System.Linq" %> <% Html.Grid(Model).Columns(col => { col.For(c => "<a href='" + Url.Action("Edit", new { userName = c }) + "' class=\"fg-button fg-button-icon-solo ui-state-default ui-corner-all\"><span class=\"ui-icon ui-icon-pencil\"></span></a>").Named("Edit").DoNotEncode(); col.For(c => Ajax.ThemeRollerActionLink("fg-button fg-button-icon-solo ui-state-default ui-corner-all", "ui-icon ui-icon-close", "Delete", new { userName = c }, new AjaxOptions { Confirm = "Delete User?", HttpMethod = "Delete", InsertionMode = InsertionMode.Replace, UpdateTargetId = "gridcontainer", OnSuccess = "successDeleteAssignment", OnFailure = "failureDeleteAssignment" })).Named("Delete").DoNotEncode(); col.For(c => c).Named("User"); }).Attributes(id => "userlist").Render(); %>

• WPF application with MS Access database as a data source

  - by Kay Zed

  I have a Microsoft Access 2010 database. Now, using Visual Studio 2010, I want to create a WPF application and add the database as a data source. The app will have a window with a frame that provides navigation through pages. No problem so far. But: -What is the right way to set up the database in this scenario? Tables only? Or must everything go via queries? (VS2010 talks about views which I assume (?) are queries) -Database data must be updatable and records can be added. Some relationships go through link tables (many-to-many) and there are nullable foreign key relationships. Must I take manual steps to make it work? -While adding the data source VS2010 created an xsd from my Access database. I think the xsd might need further tweaking for the application to work the right way. What if I change my Access database design, I'd have to regenerate the xsd again as well. Is this right, and is it the way it is usually done? OR, should I let the original Access database go and give the application the capability to create new empty databases? -How do you provide controls in a page to step through the records in a table? Is there a special database control? -What is the way (WPF class?) to load records into the data context that displays in a page? (At this level it probably does not matter what type of data source it is.)

• Struggling running ASP MVC2 on IIS6.0

  - by Luke

  Hi I could use a little Help using MVC2 on an IIS6.0 Its an MVC2 RC2 [.NET 3.5]. I followed the famous Haacked Tutorial, created a virtual folder, created a Default.aspx Website for my Project, put everything to my virtual folder. The routing is modified, using wildcard mapping [anyway its not running without, too], according to the Tutorial. I also checked, that all Webservices are running [asp.net 2 / asp.net 4 / active server pages]. The routing is working fine on my development machine, even checked it using Haacks routing debugger ... [http://haacked.com/archive/2008/03/13/url-routing-debugger.aspx] Seems fine so far, but I get only 404 - not found errors. Is there something I might be missing ? Global.asax.cs public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}.mvc/{action}/{id}", new { action = "Index", id = "" } ); routes.MapRoute( "Root", "", new { controller = "Home", action = "Index", id = "" } ); } Default.aspx.cs public void Page_Load(object sender, System.EventArgs e) { // Change the current path so that the Routing handler can correctly interpret // the request, then restore the original path so that the OutputCache module // can correctly process the response (if caching is enabled). string originalPath = Request.Path; HttpContext.Current.RewritePath(Request.ApplicationPath, false); IHttpHandler httpHandler = new MvcHttpHandler(); httpHandler.ProcessRequest(HttpContext.Current); HttpContext.Current.RewritePath(originalPath, false); }

• Is it OK to set "Cache-Control: public" when sending “304 Not Modified” for images stored in the dat

  - by Emilien

  After asking a question about sending “304 Not Modified” for images stored in the in the Google App Engine datastore, I now have a question about Cache-Control. My app now sends Last-Modified and Etag, but by default GAE alsto sends Cache-Control: no-cache. According to this page: The “no-cache” directive, according to the RFC, tells the browser that it should revalidate with the server before serving the page from the cache. [...] In practice, IE and Firefox have started treating the no-cache directive as if it instructs the browser not to even cache the page. As I DO want browsers to cache the image, I've added the following line to my code: self.response.headers['Cache-Control'] = "public" According to the same page as before: The “cache-control: public” directive [...] tells the browser and proxies [...] that the page may be cached. This is good for non-sensitive pages, as caching improves performance. The question is if this could be harmful to the application in some way? Would it be best to send Cache-Control: must-revalidate to "force" the browser to revalidate (I suppose that is the behavior that was originally the reason behind sending Cache-Control: no-cache) This directive insists that the browser must revalidate the page against the server before serving it from cache. Note that it implicitly lets the browser cache the page.

• MVC: Nested Views, and Controllers (for a website)

  - by incrediman

  I'm doing a PHP website using the MVC pattern. I am not using a framework as the site is fairly simple and I feel that this will give me a good opportunity to learn about the pattern directly. I have a couple questions. Question 1: How should I organize my views? I'm thinking of having a Page view which will have the header and footer, and which will allow for a Content view to be nested between them. Question 2: If I have 5 Content pages, should I make 5 different views that can be used as the content that is nested within the Page view? Or, should I make them all extend an abstract view called AbstractContent? Question 3: What about controllers? I think there should be one main controller at least. But then where does the request go from there? To another controller? Or should I just call the Page view and leave it at that? I thought that controllers were supposed to handle input, possibly modify a model, and select a view. But what if one of the views nested within the view that a controller calls requires additional input to be parsed? Question 4: Are controllers allowed to pass parameters into the view? Or should the controller simply modify the model, which will then affect the view? Or is the model only for DB access and other such things?

• Want custom title / image / description in facebook share link

  - by Ezop

  Hi! I am making a flash app that demonstrates potensial traffic injuries when driving at different speeds. I want the user to be able to share this information on facebook. However this demands that i can customize the text that will appear on facebook in some manner. I am making an url that is opened in a blank window (from the flash app itself). I specify the u and t parameters, putting the generated message as the t parameter. But this seems to always be overridden by the pages title. If i omit the title tag from the html code, the file name is used (also overriding the specified title). http://www.facebook.com/sharer.php?u=http://espentokerud.com/face/addiste.html&t=test; I also tried url-encoding the url, but to no avail. http://www.facebook.com/sharer.php?u=http%3a%2f%2fespentokerud.com%2fface%2faddiste.html&t=test; I also tried using the addthis API, but experience the same shortcomings. The funny thing is that if i post a swf, the title and description can be customized, and it is also possible to specify a screenshot. But if i dont post a swf, this seems to be ignored. I am aware that I can use meta tags on the html page to specify the thumbnail image, title and description, but some of this content has to be based on calculations inside the flash app. Can anyone help me out or point me in the right direction? I am thankful for any help!

• Cannot debug views in MVC2 project, getting "The resource cannot be found" error

  - by schefdev

  I'm running Visual Studio 2008 sp1 on Win7, with MVC2 RTM installed. I created a new MVC2 project using the wizard and am unable to debug specific pages. With webforms and even MVC1, I was able to sit on a View page, hit F5, and then have the integrated web server in VS2008 start on the page I was working on. Very handy for building up app logic. When I try this now I get a "The resource cannot be found" error page. I retried this just now with a stock new MVC2 Web Application project. Here are the steps I took after creating the new project to reproduce: Open up project settings. Under the Web subtab, set the Start Action to "Current Page". Leave all the other settings as is. Open one of the views up (e.g. Account/Register.aspx) Hit F5 to debug the project Note that the browser window which displays shows the error message "The resource cannot be found". The link I saw in my browser for this run was: http://localhost:49471/Views/Account/Register.aspx I did some googling and found suggestions related to ensuring all HTTP server pieces were installed. I double checked and made sure that "HTTP Errors" and "HTTP Redirection" were both installed. If I leave the project setting as it was originally, set to "Specific Page" with nothing in the text box, then routing works and I always get the default home page. I'm hoping this isn't the only option. Thanks!

• ASP.NET MVC DropDownList SelectedValue works on Edit action, but not Create action

  - by davekaro

  I have the following code in my controller (for Edit and Create): model.Templates = new SelectList(PageManagementService.PageTemplateFetchList(), "PageId", "Title", 213); the "213" is an Id for one of the pages - just using it for testing. And this is in my view (for Edit and Create): <%= this.Html.DropDownListFor(model => model.Page.TemplateId, this.Model.Templates)%> <%= this.Model.Templates.SelectedValue %> When I go to the Create form, I see the dropdown list, but the tag with value="213" is not selected. I even output the SelectedValue to make sure it's 213 - and I see 213. When I go to the Edit form, I see the dropdown list, and the tag with value="213" is selected. On the Create form, none of the tags have a "selected" attribute. On the Edit form, the tag with value="213" has the "selected" attribute. Am I missing something? What could be causing this? Anyone see this behavior before?

• How can I put multiple markers on Google maps with Javascript API v3?

  - by Doe

  Hi, I'd like to know how to put multiple markers for Google Maps using Javascript API v3. I tried the solution posted here: http://stackoverflow.com/questions/1621991/multiple-markers-in-googe-maps-api-v3-that-link-to-different-pages-when-clicked but it does not work for me for some reason. var directionDisplay; function initialize() { var myOptions = { zoom: 9, center: new google.maps.LatLng(40.81940575,-73.95647955), mapTypeId: google.maps.MapTypeId.TERRAIN } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); setMarkers(map, properties); var properties = [ ['106 Ft Washington Avenue',40.8388485,-73.9436015,'Mjg4'], ]; function setMarkers(map, buildings) { var image = new google.maps.MarkerImage('map_marker.png', new google.maps.Size(19,32), new google.maps.Point(0,0), new google.maps.Point(10,32)); var shadow = new google.maps.MarkerImage('map_marker_shadow.png', new google.maps.Size(28,32), new google.maps.Point(0,0), new google.maps.Point(10,32)); var bounds = new google.maps.LatLngBounds; for (var i in buildings) { var myLatLng = new google.maps.LatLng(buildings[i][1], buildings[i][2]); bounds.extend(myLatLng); var marker = new google.maps.Marker({ position: myLatLng, map: map, shadow: shadow, icon: image, title: buildings[i][0] }); google.maps.event.addListener(marker, 'click', function() { window.location = ('detail?b=' + buildings[i][3]); }); } map.fitBounds(bounds); } } </script> Could anyone kindly explain why this doesn't work for me?

• Crystal Reports Reportviewer - Set Datasource Dynamically Not Working :argh:

  - by Albert

  I'm running CR XI, and accessing .RPT files through a ReportViewer in my ASP.NET pages. I've already got the following code, which is supposed to set the Report Datasource dynamically. rptSP = New ReportDocument Dim rptPath As String = Request.QueryString("report") rptSP.Load(rptPath.ToString, 0) Dim SConn As New System.Data.SqlClient.SqlConnectionStringBuilder(ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString) rptSP.DataSourceConnections(SConn.DataSource, SConn.InitialCatalog).SetConnection(SConn.DataSource, SConn.InitialCatalog, SConn.UserID, SConn.Password) Dim myConnectionInfo As ConnectionInfo = New ConnectionInfo myConnectionInfo.ServerName = SConn.DataSource myConnectionInfo.DatabaseName = SConn.InitialCatalog myConnectionInfo.UserID = SConn.UserID myConnectionInfo.Password = SConn.Password 'Two new methods to loop through all objects and tables contained in the requested report and set 'login credentials for each object and table. SetDBLogonForReport(myConnectionInfo, rptSP) SetDBLogonForSubreports(myConnectionInfo, rptSP) Me.CrystalReportViewer1.ReportSource = rptSP But when I go into each .RPT file, and open up the Database Expert section, there is obviously still servernames hardcoded in there, and the code listed above doesn't seem to be able to change the servernames that are hardcoded there. I say this because I have training and production environments. When the .RPT file is hardcoded with my production server, and I open it on my training server with the code above (and the web.config has the training server in the connection string), I get the ol: Object reference not set to an instance of an object. And then if I go into the .RPT file, and change over the datasource to the training server, and try to open it again, it works fine. Why doesn't the code above overwrite the .RPT files datasource? How can I avoid having to open up each .RPT and change the datasource when migrating reports from server to server? Is there a setting in the .RPT file I'm missing or something?

• Instantiate an .aspx that is an embedded resource of an assembly

  - by asbjornu

  I have an ASP.NET (MVC) application in which I would like to load WebForms .aspx files that are embedded as resources in 3rd party assemblies. The reason I want to do this is to make a sort of "plug-in" system where a .dll file can be dropped in a folder and then picked up at runtime to provide additional functionality to the base application. I've gotten the plugin system to work (I'm using MEF) with plugins written in ASP.NET MVC (Views and Controllers), but for plain old ASP.NET (Pages), I've got myself into a bit of a problem. For the execution of the embedded .aspx file (which, in the usual WebForm way Inherits="My.BasePage") I've created a custom VirtualPathProvider, ResourceFile ControllerFactory and PageController. Within the PageController I've overridden the Execute(RequestContext) method and within it I'm trying to compile the .aspx with BuildManager.CreateInstanceFromVirtualPath(virtualPath, type). When doing this, I get the error message "Could not load type 'My.BasePage'", even though I'm giving the BuildManager the System.Type of My.BasePage in the call to CreateInstanceFromVirtualPath. I seem to be stuck at this point. I've tried to Server.Transfer() to the custom VirtualPathProvider handled URL to the same .aspx file, but that fails with the same error message. How can I help BuildManager find out where My.BasePage is defined and how come the Type requiredBaseType parameter of CreateInstanceFromVirtualPath seems to be ignored? I've tried to call BuildManager.AddReferencedAssembly(), but that only fails with "This method can only be called during the application's pre-start initialization stage". MSDN says: "The method must be called during the Application_PreStartInit stage of the application", but I have no such event in my HttpApplication object and find absolutely zero information about it on the internet. Either way, I don't want to be calling BuildManager.AddReferencedAssembly() in or before the Application_Start event, since that makes me have to recycle the whole application to be able to add new plugins to the system. Does anyone have any clues? Any other ideas on how I can "execute" an .aspx file that is embedded as a resource within an assembly through reflection? Can I for instance pre-compile the .aspx file within the same assembly as the base Page class it inherits?

• VS2010 Ultimate - Unable to launch ASP.NET Development Server

  - by sohum

  I've worked with ASP.NET once before and had a project where it was potentially useful, so I started creating an ASP.NET website as part of a solution that contained several C# class libraries. I'm using Visual Studio 2010 Ultimate Edition and Windows 7 Professional x64. The issue is that when I try to debug my website project, I get the following error message: Unable to launch the ASP.NET Development Server There's no other information (it seems a popular variant is the "port in use" error). Interestingly, I can run single pages on the application by right-clicking on the ASPX and selecting "View in Browser". This does not allow me to debug into my breakpoints, though. I have no clue what the problem could be. I'm running VS2010 in Administrator mode. One of the questions that popped up here suggested I uncomment the "127.0.0.1 localhost" line from my HOSTS file, which I did, and restarted VS with no luck. I also tried both setting a static port for the web server to run on as well as let it dynamically generate one. Both do not help the situation. Any help? Thanks.

• Jquery.get() not returning any data

  - by David Waters

  Hi I am trying to scrape other people web pages (for the forces of good not evil). I am currently trying to do this with javascript/jquery from with in a browser. I am finding that the no data is returned from the jquery.get() success call back function. My code. $.get('http://www.google.co.uk/', function (data, textStatus, XMLHttpRequest){ alert("status " + textStatus); alert('data:' + data); window.data=data; window.textStatus=textStatus; window.httpReq = XMLHttpRequest}); In my mind this should simply do a get on google store the data in window.data and we are all good. What happens is we get textStatus == success and data == "". the status on the XMLHttpRequest is 4(success). I have looked at the network traffic using a transparent proxy (Charles) and everything looks find there http status 200 plenty of data being returned. I am running this just from the Firebug console in Firefox. Any ideas?

• How to programmatically show & hide BalloonPopupExtender?

  - by Danferd

  I have a page that will be having few buttons that will redirect user to certain pages that required them to login before to proceed to the page. I would like to have something like, when user click on the button that required login and if user is not logged in prior to the click, a tooltip will show up beside the 'User ID' textbox to inform user to login in order to proceed. So, I implemented the jQuery Tooltipster in the page to show the tooltip message. I'm having problem on IE8 in Windows XP where the first click on the button, the tooltip would show up, but the second click it wouldn't then the third click, it shows up again and then the fourth click, it wouldn't! But for IE8 in Windows 7, IE9 & IE10, they have no such problem. Any idea how to fix this? The 'imgBtnKISS' & 'lnkBtnKISS' buttons are located in a content page but the tooltip and the 'User ID' textbox are in a master page. Below is the code that how I call the tooltip: function loginAlertMsg() { $('.tooltip').tooltipster({ trigger: 'custom', position: 'left', onlyOne: false, content: 'Login required! Please login to proceed.' }); $('#ctl00_txtID').tooltipster('show'); $('#ctl00_txtID').focus(); } Private Sub KISS_Click() Handles imgBtnKISS.Click, lnkBtnKISS.Click If Not bIsRefresh Then '==Detect User Login Status== Session(sesClickFromIcon) = toKISS If Session(USR.sesLogin) Is Nothing Then '//User NOT LOGIN. If (Not Page.ClientScript.IsStartupScriptRegistered("loginAlertMsg")) Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "loginAlertMsg", "loginAlertMsg();", True) End If Exit Sub Else If Trim(CType(Session.Item(USR.sesLogin), Boolean)) <> True Then '//User NOT LOGIN.
