• Impatient Customers Make Flawless Service Mission Critical for Midsize Companies

  - by Richard Lefebvre

  At times, I can be an impatient customer. But I’m not alone. Research by The Social Habit shows that among customers who contact a brand, product, or company through social media for support, 32% expect a response within 30 minutes and 42% expect a response within 60 minutes! 70% of respondents to another study expected their complaints to be addressed within 24 hours, irrespective of how they contacted the company. I was intrigued when I read a recent blog post by David Vap, Group Vice President of Product Development for Oracle Service Cloud. It’s about “Three Secrets to Innovation” in customer service. In David’s words: 1) Focus on making what’s hard simple 2) Solve real problems for real people 3) Don’t just spin a good vision. Do something about it  I believe midsize companies have a leg up in delivering on these three points, mainly because they have no other choice. How can you grow a business without listening to your customers and providing flawless service? Big companies are often weighed down by customer service practices that have been churning in bureaucracy for years or even decades. When the all-in-one printer/fax/scanner I bought my wife for Christmas (call me a romantic) failed after sixty days, I wasted hours of my time navigating the big brand manufacturer’s complex support and contact policies only to be offered a refurbished replacement after I shipped mine back to them. There was not a happy ending. Let's just say my wife still doesn't have a printer.  Young midsize companies need to innovate to grow. Established midsize company brands need to innovate to survive and reach the next level. Midsize Customer Case Study: The Boston Globe The Boston Globe, established in 1872 and the winner of 22 Pulitzer Prizes, is fighting the prevailing decline in the newspaper industry. Businessman John Henry invested in the Globe in 2013 because he, “…believes deeply in the future of this great community, and the Globe should play a vital role in determining that future”. How well the paper executes on its bold new strategy is truly mission critical—a matter of life or death for an industry icon. This customer case study tells how Oracle’s Service Cloud is helping The Boston Globe “do something about” and not just “spin” it’s strategy and vision via improved customer service. For example, Oracle RightNow Chat Cloud Service is now the preferred support channel for its online environments. The average e-mail or phone call can take three to four minutes to complete while the average chat is only 30 to 40 seconds. It’s a great example of one company leveraging technology to make things simpler to solve real problems for real people.

• OData &ndash; The easiest service I can create

  - by Jon Dalberg

  I wanted to create an OData service with the least amount of code so I fired up Visual Studio and got cracking. I decided to serve up a list of naughty words and make them read-only. Create a new web project. I created an empty MVC 2 application but MVC is not required for OData. Add a new WCF Data Service to the project. I named mine NastyWords.svc since I’m serving up a list of nasty words. Add a class to expose via the service: NastyWord 1: [DataServiceKey("Word")] 2: public class NastyWord 3: { 4: public string Word { get; set; } 5: }   I need to be able to uniquely identify instances of NastyWords for the DataService so I used the DataServiceKey attribute with the “Word” property as the key. I could have added an “ID” property which would have uniquely identified them and would then not need the “DataServiceKey” attribute because the DataService would apply some reflection and heuristics to guess at which property would be the unique identifier. However, the words themselves are unique so adding an “ID” property would be redundantly repetitive. Then I created a data source to expose my NastyWord objects to the service. This is just a simple class with IQueryable<T> properties exposing the entities for my service: 1: public class NastyWordsDataSource 2: { 3: private static IList<NastyWord> words = new List<NastyWord> 4: { 5: new NastyWord{ Word="crap"}, 6: new NastyWord{ Word="darn"}, 7: new NastyWord{ Word="hell"}, 8: new NastyWord{ Word="shucks"} 9: }; 10:   11: public NastyWordsDataSource() 12: { 13: NastyWords = words.AsQueryable(); 14: } 15:   16: public IQueryable<NastyWord> NastyWords { get; private set; } 17: }   Now I can go to the NastyWords.svc class and tell it which data source to use and which entities to expose: 1: public class NastyWords : DataService<NastyWordsDataSource> 2: { 3: // This method is called only once to initialize service-wide policies. 4: public static void InitializeService(DataServiceConfiguration config) 5: { 6: config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); 7: config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; 8: } 9: }   Compile and browse to my NastWords.svc and weep with joy Now I can query my service just like any other OData service. Next time, I’ll modify this service to allow updates to sent so I can build up my list of nasty words. Enjoy!

• Updating an Entity through a Service

  - by GeorgeK

  I'm separating my software into three main layers (maybe tiers would be a better term): Presentation ('Views') Business logic ('Services' and 'Repositories') Data access ('Entities' (e.g. ActiveRecords)) What do I have now? In Presentation, I use read-only access to Entities, returned from Repositories or Services, to display data. $banks = $banksRegistryService->getBanksRepository()->getBanksByCity( $city ); $banksViewModel = new PaginatedList( $banks ); // some way to display banks; // example, not real code I find this approach quite efficient in terms of performance and code maintanability and still safe as long as all write operations (create, update, delete) are preformed through a Service: namespace Service\BankRegistry; use Service\AbstractDatabaseService; use Service\IBankRegistryService; use Model\BankRegistry\Bank; class Service extends AbstractDatabaseService implements IBankRegistryService { /** * Registers a new Bank * * @param string $name Bank's name * @param string $bik Bank's Identification Code * @param string $correspondent_account Bank's correspondent account * * @return Bank */ public function registerBank( $name, $bik, $correspondent_account ) { $bank = new Bank(); $bank -> setName( $name ) -> setBik( $bik ) -> setCorrespondentAccount( $correspondent_account ); if( null === $this->getBanksRepository()->getDefaultBank() ) $this->setDefaultBank( $bank ); $this->getEntityManager()->persist( $bank ); return $bank; } /** * Makes the $bank system's default bank * * @param Bank $bank * @return IBankRegistryService */ public function setDefaultBank( Bank $bank ) { $default_bank = $this->getBanksRepository()->getDefaultBank(); if( null !== $default_bank ) $default_bank->setDefault( false ); $bank->setDefault( true ); return $this; } } Where am I stuck? I'm struggling about how to update certain fields in Bank Entity. Bad solution #1: Making a series of setters in Service for each setter in Bank; - seems to be quite reduntant, increases Service interface complexity and proportionally decreases it's simplicity - something to avoid if you care about code maitainability. I try to follow KISS and DRY principles. Bad solution #2: Modifying Bank directly through it's native setters; - really bad. If you'll ever need to move modification into the Service, it will be pain. Business logic should remain in Business logic layer. Plus, there are plans on logging all of the actions and maybe even involve user permissions (perhaps, through decorators) in future, so all modifications should be made only through the Service. Possible good solution: Creating an updateBank( Bank $bank, $array_of_fields_to_update) method; - makes the interface as simple as possible, but there is a problem: one should not try to manually set isDefault flag on a Bank, this operation should be performed through setDefaultBank method. It gets even worse when you have relations that you don't want to be directly modified. Of course, you can just limit the fields that can be modified by this method, but how do you tell method's user what they can and cannot modify? Exceptions?

• OSB, Service Callouts and OQL - Part 1

  - by Sabha

  Oracle Fusion Middleware customers use Oracle Service Bus (OSB) for virtualizing Service endpoints and implementing stateless service orchestrations. Behind the performance and speed of OSB, there are a couple of key design implementations that can affect application performance and behavior under heavy load. One of the heavily used feature in OSB is the Service Callout pipeline action for message enrichment and invoking multiple services as part of one single orchestration. Overuse of this feature, without understanding its internal implementation, can lead to serious problems. This post will delve into OSB internals, the problem associated with usage of Service Callout under high loads, diagnosing it via thread dump and heap dump analysis using tools like ThreadLogic and OQL (Object Query Language) and resolving it. The first section in the series will mainly cover the threading model used internally by OSB for implementing Route Vs. Service Callouts. Please refer to the blog post for more details.

• Java Cloud Service for developers

  - by JuergenKress

  The advent of cloud computing has reinvented application development for many companies. “That’s the beauty of the cloud,” says Cameron Purdy, vice president of development, Oracle. “It dramatically improves developer productivity because they can do what they do best without having to manage complex development, testing, staging, and production environments.” The key is to find a platform that doesn’t impose proprietary restrictions or force developers to learn new tools. For example, Oracle Java Cloud Service is an enterprise-grade platform as a service for building and deploying Java EE, Oracle WebLogic Server, and Oracle Application Development Framework (Oracle ADF) applications. “It’s designed to be flexible and easy to use,” says Purdy. “And it is also a standards-based solution -it’s not proprietary and there is no cloud lock-in. Developers get instant access to an enterprise-grade environment for a simple, monthly subscription.” Oracle Java Cloud Service instances are created with just a few clicks, so businesses can create a rich application development environment within minutes. Running on Oracle WebLogic Server and Oracle Exalogic, the underlying infrastructure also leverages Oracle Fusion Middleware’s integration with common services. For example, instances come integrated and preconfigured with optimized Oracle Database and Oracle Identity Management configurations. Based on Oracle Enterprise Manager, the Oracle Java Cloud Service console lets customers easily manage and monitor their Oracle Java Cloud Service instances. The open nature of the Oracle Java Cloud Service lets developers integrate through Web services such as SOAP and REST APIs, as well as use their favorite developer tools, whether they are out-of-the-box tools such as Maven and Ant or the productivity features built into Oracle JDeveloper, Oracle Enterprise Pack for Eclipse, or NetBeans IDE. The service allows for the seamless movement of applications between on-premise Oracle WebLogic Server domains and instances of Oracle Java Cloud Service within Oracle Cloud. This approach allows flexibility to mix and match the use of on-premise environments with cloud instances for development, test, and production environments.

• Defining a service layer: the text-based adventure

  - by Stacy Vicknair

  Applications these days have more options than ever for a user interface, and it’s only going to grow. A successful product might require native applications for mobile devices, a regular web implementation, or even a gaming console. These systems often will be centralized and data driven. The solution is one that’s fairly solitary, a service layer! Simply put, take what’s shared and put it behind a physical or abstract layer that defines the boundary between the specific user interface and the shared content.   I know, I know, none of this is complicated. But some times it can be difficult to discern what belongs on which side of the line. For instance, say we’re creating a service that will provide content for both an ASP.NET MVC application and a WP7 application. Although the content served to each application is the same, there are different paradigms and patterns for displaying that data in the different environments. In ASP.NET MVC, you may create a model specific to a page that combines necessary information. In the WP7 application you might require different sets of data that you will connect via MVVM with the view. The general rule of thumb is that any shared content, business rules, or data should exist separately. Any element that is specific to the current UI implementation should be included in a separate library or with the UI implementation itself. The WP7 application doesn’t need my MVC specific model classes. My MVC application doesn’t require those INotifyPropertyChanged viewmodels that the WP7 application depends on. In both cases, there should be additional processing done above the service layer to massage the data to the application’s specific needs.   Service-ocalypse: the text based adventure What helps me the most about deciding whether or not something belongs coupled to the UI implementation or in the shared implementation is thinking of the simplest implementation you could have: a console application. You might have played a game like Peasant’s Quest: The console app is the text based adventure game version of your application. If you’re service was consumed in its simplest form, you would simply have a console based API for it that issues requests. Maybe those requests aren’t SWIM TO BOAT, but they might be CREATE USER JOHN. If I issue a request, I expect that request to be issued to the service. If the service has any exceptions or issues with my input, that business logic should be encapsulated in that service, not implemented in the UI. The service layer should be your functional application in its entirety, and anything above that layer should only assist with the display of that information.

• Interaction of a GUI-based App and Windows Service

  - by psubsee2003

  I am working on personal project that will be designed to help manage my media library, specifically recordings created by Windows Media Center. So I am going to have the following parts to this application: A Windows Service that monitors the recording folder. Once a new recording is completed that meets specific criteria, it will call several 3rd party CLI Applications to remove the commercials and re-encode the video into a more hard-drive friendly format. A controller GUI to be able to modify settings of the service, specifically add new shows to watch for, and to modify parameters for the CLI Applications A standalone (GUI-based) desktop application that can perform many of the same functions as the windows service, expect manually on specific files instead of automatically based on specific criteria. (It should be mentioned that I have limited experience with an application of this complexity, and I have absolutely zero experience with Windows Services) Since the 1st and 3rd bullet share similar functionality, my design plan is to pull the common functionality into a separate library shared by both parts applications, but these 2 components do not need to interact otherwise. The 2nd and 3rd bullets seem to share some common functionality, both will have a GUI, both will have to help define similar parameters (one to send to the service and the other to send directly to the CLI applications), so I can see some advantage to combining them into the same application. On the other hand, the standalone application (bullet #3) really does not need to interact with the service at all, except for possibly sharing a few common default parameters that can easily be put into an XML in a common location, so it seems to make more sense to just keep everything separate. The controller GUI (2nd bullet) is where I am stuck at the moment. Do I just roll this functionality (allow for user interaction with the service to update settings and criteria) into the standalone application? Or would it be a better design decision to keep them separate? Specifically, I'm worried about adding the complexity of communicating with the Windows Service to the standalone application when it doesn't need it. Is WCF the right approach to allow the controller GUI to interact with the Windows Service? Or is there a better alternative? At the moment, I don't envision a need for a significant amount of interaction, maybe just adding a new task once in a while and occasionally tweaking a parameter, but when something is changed, I do expect the windows service to immediately use the new settings.

• Plugins in Ops Center and Cloud Control

  - by Owen Allen

  Cloud Control just released an updated plugin for Oracle Virtual Networking, so I thought I'd mention a bit about how both Ops Center and Cloud Control use plugins. On the Ops Center side, we have a plugin to connect Ops Center to Cloud Control, letting them share monitoring data. This guide explains how to install and use that plugin. In Cloud Control, they have a more extensive collection of plugins, letting you link Cloud Control with a variety of other products. The Cloud Control library plug-in tab goes into more detail about how you can use these plugins in your environment.

• 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.)

• Access violations in strange places when using Windows file dialogs

  - by Robert Oschler

  A long time ago I found out that I was getting access violations in my code due to the use of the Delphi Open File and/or Save File dialogs, which encapsulate the Windows dialogs. I asked some questions on a few forums and I was told that it may have been due to the way some programs add hooks to the shell system that result in DLLs getting injected in every process, some of which can cause havoc with a program. For the record, the programming environment I use is Delphi 6 Professional running on Windows XP 32-bit. At the time I got around it by not using Delphi's Dialog components and instead calling straight into comdlg32.dll. This solved the problem wonderfully. Today I was working with memory mapped files for the first time and sure enough, access violations started cropping up in weird parts of the code. I tried my comdlg32.dll direct calls and this time it didn't help. To isolate the problem as a test I created a list box with the exact same files I was using during testing. These are the exact same test files I was selecting from an Open File dialog and then launching my memory mapped file with. I set things up so that by clicking on a file in the list box, I would use that file in my memory mapped file test instead of calling into a comdlg32.dll dialog function to select a test file. Again, the access violatons vanished. To show you how dramatic a fix it was I went from experiencing an access violation within 1 to 3 trials to none at all. Unfortunately, it's going to bite me later on of course when I do need to use file dialogs. Has anyone else dealt with this issue too and found the real culprit? Did any of you find a solution I could use to fix this problem instead of dancing around it like I am now? Thanks in advance.

• Changes in Access DB are not saved since updating to Windows 7

  - by ytoledano

  Hi I'm working with a program that accesses an MS-Access DB. The problem is that if I open the db file with Access, the values I see aren't the values I see when I'm using the program. For example, There is a table PARAMS with various program variables, one of them is the date I last loaded a certain file. In access it reads April 12th 2010, while in the program it reads May 7th 2010 (this is correct). April 12th is about the time I upgraded the computer to Windows 7. Also, the mdb file sits next to the program executable in C:\Program Files (x86); and I know that Win7 doesn't allow programs to write to the program files dir. So where are the changes saved? What I've tried: I've tried opening the mdb file on another computer - still reads the wrong (old) values I've tried copying the entire program dir to a different folder - now both the program and ms-access read the wrong values. Can someone tell me how to get a version of the DB with all the values up to date with the program? Thanks.

• What's the best way to access a MS Access database using PHP?

  - by Jack Roscoe

  Hi, I need to access some data from an MS Access database and retrieve some data from it using PHP. I've looked around the web, and found the following line which seems to correctly connect to the database: $conn->Open("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=C:\wamp\www\data\MYDB.mdb"); However, I have tried to retrieve some data in the following way: $query = "SELECT pageid FROM pages_table"; $result = mysqli_query($conn, $query); $amount_of_pages = 0; if(mysqli_num_rows($result) <= 0) echo "No results found."; else while($row = mysqli_fetch_array($result, MYSQL_ASSOC)) $amount_of_pages++; And was presented with the following errors: Warning: mysqli_query() expects parameter 1 to be mysqli, object given in C:\wamp\www\data\index.php on line 19 Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, null given in C:\wamp\www\data\index.php on line 23 No results found. I don't really understand the connection to the Access database, is there something I should be doing differently? Thanks in advance for any help.

• Access Denied

  - by Tony Davis

  When Microsoft executives wake up in the night screaming, I suspect they are having a nightmare about their own version of Frankenstein's monster. Created with the best of intentions, without thinking too hard of the long-term strategy, and having long outlived its usefulness, the monster still lives on, occasionally wreaking vengeance on the innocent. Its name is Access; a living synthesis of disparate body parts that is resistant to all attempts at a mercy-killing. In 1986, Microsoft had no database products, and needed one for their new OS/2 operating system, the successor to MSDOS. In 1986, they bought exclusive rights to Sybase DataServer, and were also intent on developing a desktop database to capture Ashton-Tate's dominance of that market, with dbase. This project, first called 'Omega' and later 'Cirrus', eventually spawned two products: Visual Basic in 1991 and Access in late 1992. Whereas Visual Basic battled with PowerBuilder for dominance in the client-server market, Access easily won the desktop database battle, with Dbase III and DataEase falling away. Access did an excellent job of abstracting and simplifying the task of building small database applications in a short amount of time, for a small number of departmental users, and often for a transient requirement. There is an excellent front end and forms generator. We not only see it in Access but parts of it also reappear in SSMS. It's good. A business user can pull together useful reports, without relying on extensive technical support. A skilled Access programmer can deliver a fairly sophisticated application, whilst the traditional client-server programmer is still sharpening his pencil. Even for the SQL Server programmer, the forms generator of Access is useful for sketching out application designs. So far, so good, but here's where the problems start; Access ties together two different products and the backend of Access is the bugbear. The limitations of Jet/ACE are well-known and documented. They range from MDB files that are prone to corruption, especially as they grow in size, pathetic security, and "copy and paste" Backups. The biggest problem though, was an infamous lack of scalability. Because Microsoft never realized how long the product would last, they put little energy into improving the beast. Microsoft 'ate their own dog food' by using Access for Microsoft Exchange and Outlook. They choked on it. For years, scalability and performance problems with Exchange Server have been laid at the door of the Jet Blue engine on which it relies. Substantial development work in Exchange 2010 was required, just in order to improve the engine and storage schema so that it more efficiently handled the reading and writing of mails. The alternative of using SQL Server just never panned out. The Jet engine was designed to limit concurrent users to a small number (10-20). When Access applications outgrew this, bitter experience proved that there really is no easy upgrade path from Access to SQL Server, beyond rewriting the whole lot from scratch. The various initiatives to do this never quite bridged the cultural gulf between Access and a true relational database So, what are the obvious alternatives for small, strategic database applications? I know many users who, for simple 'list maintenance' requirements are very happy using Excel databases. Surely, now that PowerPivot has led the way, it is time for Microsoft to offer a new RAD package for database application development; namely an Excel-based front end for SQL Server Express. In that way, we'll have a powerful and familiar front end, to a scalable database, and a clear upgrade path when an app takes off and needs to go enterprise. Cheers, Tony.

• Sharepoint : Access denied when editing a page (because of page layout) or list item

  - by tinky05

  I'm logged in as the System Account, so it's probably not a "real access denied"! What I've done : - A custom master page - A custom page layout from a custom content type (with custom fields) If I add a custom field (aka "content field" in the tools in SPD) in my page layout, I get an access denied when I try to edit a page that comes from that page layout. So, for example, if I add in my page layout this line in a "asp:content" tag : I get an access denied. If I remove it, everyting is fine. (the field "test" is a field that comes from the content type). Any idea? UPDATE Well, I tried in a blank site and it worked fine, so there must be something wrong with my web application :( UPDATE #2 Looks like this line in the master page gives me the access denied : <SharePoint:DelegateControl runat="server" ControlId="PublishingConsole" Visible="false" PrefixHtml="&lt;tr&gt;&lt;td colspan=&quot;0&quot; id=&quot;mpdmconsole&quot; class=&quot;s2i-consolemptablerow&quot;&gt;" SuffixHtml="&lt;/td&gt;&lt;/tr&gt;"></SharePoint:DelegateControl> UPDATE #3 I Found http://odole.wordpress.com/2009/01/30/access-denied-error-message-while-editing-properties-of-any-document-in-a-moss-document-library/ Looks like a similar issue. But our Sharepoint versions are with the latest updates. I'll try to use the code that's supposed to fix the lists and post another update. ** UPDATE #4** OK... I tried the code that I found on the page above (see link) and it seems to fix the thing. I haven't tested the solution at 100% but so far, so good. Here's the code I made for a feature receiver (I used the code posted from the link above) : using System; using System.Collections.Generic; using System.Text; using Microsoft.SharePoint; using System.Xml; namespace MyWebsite.FixAccessDenied { class FixAccessDenied : SPFeatureReceiver { public override void FeatureActivated(SPFeatureReceiverProperties properties) { FixWebField(SPContext.Current.Web); } public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { //throw new Exception("The method or operation is not implemented."); } public override void FeatureInstalled(SPFeatureReceiverProperties properties) { //throw new Exception("The method or operation is not implemented."); } public override void FeatureUninstalling(SPFeatureReceiverProperties properties) { //throw new Exception("The method or operation is not implemented."); } static void FixWebField(SPWeb currentWeb) { string RenderXMLPattenAttribute = "RenderXMLUsingPattern"; SPSite site = new SPSite(currentWeb.Url); SPWeb web = site.OpenWeb(); web.AllowUnsafeUpdates = true; web.Update(); SPField f = web.Fields.GetFieldByInternalName("PermMask"); string s = f.SchemaXml; Console.WriteLine("schemaXml before: " + s); XmlDocument xd = new XmlDocument(); xd.LoadXml(s); XmlElement xe = xd.DocumentElement; if (xe.Attributes[RenderXMLPattenAttribute] == null) { XmlAttribute attr = xd.CreateAttribute(RenderXMLPattenAttribute); attr.Value = "TRUE"; xe.Attributes.Append(attr); } string strXml = xe.OuterXml; Console.WriteLine("schemaXml after: " + strXml); f.SchemaXml = strXml; foreach (SPWeb sites in site.AllWebs) { FixField(sites.Url); } } static void FixField(string weburl) { string RenderXMLPattenAttribute = "RenderXMLUsingPattern"; SPSite site = new SPSite(weburl); SPWeb web = site.OpenWeb(); web.AllowUnsafeUpdates = true; web.Update(); System.Collections.Generic.IList<Guid> guidArrayList = new System.Collections.Generic.List<Guid>(); foreach (SPList list in web.Lists) { guidArrayList.Add(list.ID); } foreach (Guid guid in guidArrayList) { SPList list = web.Lists[guid]; SPField f = list.Fields.GetFieldByInternalName("PermMask"); string s = f.SchemaXml; Console.WriteLine("schemaXml before: " + s); XmlDocument xd = new XmlDocument(); xd.LoadXml(s); XmlElement xe = xd.DocumentElement; if (xe.Attributes[RenderXMLPattenAttribute] == null) { XmlAttribute attr = xd.CreateAttribute(RenderXMLPattenAttribute); attr.Value = "TRUE"; xe.Attributes.Append(attr); } string strXml = xe.OuterXml; Console.WriteLine("schemaXml after: " + strXml); f.SchemaXml = strXml; } } } } Just put that code as a Feature Receiver, and activate it at the root site, it should loop trough all the subsites and fix the lists. SUMMARY You get an ACCESS DENIED when editing a PAGE or an ITEM You still get the error even if you're logged in as the Super Admin of the f****in world (sorry, I spent 3 days on that bug) For me, it happened after an import from another site definition (a cmp file) Actually, it's supposed to be a known bug and it's supposed to be fixed since February 2009, but it looks like it's not. The code I posted above should fix the thing.

• WebBrowser control won't display an https site that IE8 on the same PC will

  - by Velika

  In IE8, I get the follow warning, but if I choose to continue the site displays properly. There is a problem with this website's security certificate. The security certificate presented by this website was issued for a different website's address. Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server. We recommend that you close this webpage and do not continue to this website. Click here to close this webpage. Continue to this website (not recommended). More information In the WebBrowser control, I get this at first: Navigation to the webpage was canceled What you can try: Refresh the page. When I hit the refresh teh page, this time, I get the same wanting as I originally get in IE8, but when I click "Continue to this website (not recommended)", the page refresh again, displaying the same warning. What can I do to get the site to display in the WebBrowser control as it does in IE8. I would've thought that the control would be using the same core logic and therefore expected the same result.

• Web service SSL handshake fails in production environment unless SSL debugging enabled

  - by JST

  Scenario: calling a client web service over SSL (https) with mutual SSL authentication. Different service endpoint URLs and certs (both keystore and truststore) for test vs. production environments. Both test and production environments run tomcat / JBoss clustered. Production environment has load balancing / BigIP, runs Blade and non-Blade machines. Truststore is set (using -Djavax.net.ssl.trustStore=value) at startup. Keystore is set using System.setProperty("javax.net.ssl.keyStore", "value") in Java code. Web service call made using Axis2. All works fine in test environment, but when we moved to production environment (6 servers), it appears certs are not being forwarded for the handshake. Here's what we've done: in test environment, handshake using test versions of certs has been working all along, with no ssl debugging enabled confirmed in test environment that handshake with client production endpoint succeeds (production certs, both ours and theirs, are fine) -- this was done using -Djavax.net.debug=handshake,ssl confirmed that the error condition occurs on all 6 production servers took one server out of the cluster, turned on ssl debugging for just that one (with a restart), hit it directly, handshake works! switched to a different server without the debugging turned on, handshake error condition occurs turned debugging on on that second server (with a restart), hit it directly, handshake works! From the evidence, it seems like somehow the debugging being enabled causes the certificates to be properly retrieved/conveyed, although that makes no sense! I wonder whether somehow the enabled debugging makes the system pay attention to the System.setProperty call, and ignore it otherwise. However, in local and test environments, handshake worked without debugging enabled. Do I maybe need to be setting keystore on server startup like I'm setting truststore? Have been avoiding that because the keystore will differ for each of our test environments (16 of them).

• Error using ASP.NET 3.5 Chart control within a Repeater control

  - by tuseau

  Hi, I'm getting the error "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd" at runtime from my Chart control. I have read one solution to this error message as documented here: http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/thread/1dc4b352-c9a5-49dc-8f35-9b176509faa1/ but this does not solve my problem. I have the Chart within a Repeater control, which is within an ajax UpdatePanel. When I take the chart out of the Repeater (but leave it in the UpdatePanel), it works. So I'm thinking it is to do with the Repeater. Anyone got any ideas? Thanks in advance.

• Source Control - XCode - Visual Studio 2005/2008 / 2010

  - by Mick Walker

  My apologies if this has been asked before, I wasnt quite sure if this question should be asked on a programming forum, as it more relates to programming environment than a particular technology, so please accept my (double) appologies if I am posting this in the wrong place, my logic in this case was if it effects the code I write, then this is the place for it. At home, I do a lot of my development on a Mac Pro, I do development for the Mac, iPhone and Windows on this machine (Xcode & Visual Studio - (multiple versions installed in bootcamp, but generally I run it via Parallels)). When visiting a client, I have a similar setup, but on my MacBook Pro. What I want is a source control solution to install on the Mac Pro, that will support both XCode and multiple versions of visual studio, so that when I visit a client, I can simply grab the latest copy from source control via the MacBook Pro. Whilst visiting the client, he / she may suggest changes, and minor ones I would tend to make on site, so I need the ability to merge any modified code back into the trunk of the project / solution when I return home. At the moment, I am using no source control at all, and rely on simply coping folders and overwriting them when I return from a client- thats my 'merge'!!! I was wondering if anyone had any ideas of a source provider I could use, which would support both Windows and Mac development environments, and is cheap (free would be better).

• MDE Access decrypt JDBC

  - by michelemarcon

  I want to perform JDBC SQL queries on a MDE Access file. I've set up the data source ODBC and everything worked well for a MDE file. Now, I'm working with a newer version of the MDE file, and here is the result: java.sql.SQLException: [Microsoft][Driver ODBC Microsoft Access] Cannont read record. Read authorization unavailable for "tbl_mytable". If I open the MDE with Access Runtime I am asked for a password, and after leaving a blank password I can see all the data. Of course, "tbl_mytable" does exist inside the database.
