  • Disable cache in Silverlight HttpWebRequest

    - by synergetic
    My Silverlight4 app is hosted in ASP.NET MVC 2 web application. I do web request through HttpWebRequest class but it gives back a result previously cached. How to disable this caching behavior? There are some links which talks about HttpWebRequest in .NET but Silverlight HttpWebrequest is different. Someone suggested to add unique dummy query string on every web request, but I'd prefer more elegant solution. I also tried the following, but it didn't work: _myHttpWebRequest.BeginGetRequestStream(new AsyncCallback(BeginRequest), new Guid()); In fact, by setting browser history settings it is possible to disable caching. See the following link: http://stackoverflow.com/questions/3027145/asp-net-mvc-with-sql-server-backend-returns-old-data-when-query-is-executed But asking a user to change browser settings is not an option for me.

  • SQLCEException was unhandled: Internal Error: Cannot open the shared memory region

    - by dwaz
    I am trying to do a TableAdapter.Fill(dataTable) and it fails with the above error. Here is the code in Zenware.DataSet.Designer.cs [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.ComponentModel.DataObjectMethodAttribute(global::System.ComponentModel.DataObjectMethodType.Fill, true)] public virtual int Fill(ZenwareDataSet.BatchPDADataTable dataTable) { this.Adapter.SelectCommand = this.CommandCollection[0]; if ((this.ClearBeforeFill == true)) { dataTable.Clear(); } int returnValue = this.Adapter.Fill(dataTable); // <---Fails here. return returnValue; } This is generated code. Maybe there is something that I need to change? I am wondering if my app has multiple connections to the database. What can this be? Thanks for any help you can provide.

  • Advice? SSO in N-tiered SOA with mixture of REST and SOAP services

    - by Tyler
    Hi gang, We are moving to SSO in our N-tiered SOA applications. If all the services were SOAP, I'd be ok with just the WS-Security, WS-Trust, WS-Federation set of protocols. My problem is that many of the services are RESTful (ironic) and those protocols do not address REST services. What is your advice for SSO protecting the REST services in an N-tiered SOA architecture with the following requirements: ideally claims-based identity information available to the REST services original user (eg. bootstrap) information must flow through the tiers so that each service can "ActAs" or "OnBehalfOf" the user support sequences like: WebApp -- REST Svc -- SOAP Svc WebApp -- REST Svc1 -- REST Svc2 WebApp -- SOAP Svc -- REST Svc WebApp -- SOAP Svc1 -- SOAP Svc2 support SSO (and SSOff) service/web app platforms: ASP.Net and WCF Java end-user client platforms: .Net (WSE 3.0 and WCF) flash 10 java javascript and AJAX Normally I'm good at climbing / bashing my way through walls, but this one's knocked me flat. Hopefully with your help, we can get over this one. Thanks, Tyler

  • Remote Backup User Data on iPhone

    - by Eric
    I wrote a few iPhone apps using Core Data for persistent storage. Everything is working great but I would like to add the ability for users to back up their data to a PC (via WiFi to a PC app) or to a web server. This is new to me and I can't seem to figure out where to begin researching the problem. I don't want to overcomplicate the issue if there is an easy way to implement this. Is anyone familiar enough with what I am looking to do to point me in the right direction or give me a high level overview of what I should be considering? The data is all text and would be perfectly stored in .csv files if that matters.

  • itunes connect rejection: "The binary you uploaded was invalid. A pre-release beta version of the SD

    - by Adam
    I'm having trouble submitting apps on Apple's app store. I was using a beta version of xcode- 3.2.3/iphone sdk 4.0- and I assumed that if I set the base sdk and deployment target to an acceptable version it would work, but it didn't. I deleted the beta version of xcode/sdk using "sudo /Developer/Library/uninstall-devtools --mode=all" and did a fresh install of the old release version- xcode 3.2.2/iphone sdk 3.2- but I still have the same problem. Has anyone run into this before? Is there something left over from the beta version that could still be hanging around causing problems?

  • Building Eclipse RCP application, running fails

    - by Raven
    Hi, after successfully building my application the start fails because it relies on config files which are located in the META-INF directory and after the build this directory is zipped into a jar file, hence making it unable to access the config files. After manually unzipping the jar, deleting the jar and renaming the directory with xxx.jar the program runs without a problem. The config files are needed for SSO login (Kerberos). Here is the code: Bundle bundle = Platform.getBundle(Application.PLUGIN_ID); String path; try { path = new URL(bundle.getLocation().substring(18)).getPath(); } catch (MalformedURLException e1) { System.out.println(e1); path=""; } System.setProperty("java.security.auth.login.config",path+"META-INF/jaas-win.config"); Path variable contains something like "plugin/mydomain.pluginame-xxxx.jar/" But it seems that the System needs the jar unzipped. That am I doing wrong building the app? Thanks

  • NSFetchedResultsController when navigating from one UITableViewController to another ...

    - by wgpubs
    In my core data model I have a Person entity that has a "to many" relationship a Course entity (I also have an inverse "to one" relationship from Course to Person). Now I have a subclassed UITableViewController that uses a NSFetchedResultsController to display Person objects which works fine. I have this set up so that when you click on a Person it publishes another subclassed UITableViewController that uses a NSFetchedController as well to display the Courses associated to the person. PROBLEM: I get this exception whenever I click on the Person and attempt to display the Course UITableViewController ... "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'keypath name not found in entity '" Any ideas on how to resolve or troubleshoot? The code between the two ViewControllers is almost identical except for the NSFetchedResultsController being configured for "Person" entities in one and "Course" entities in another

  • How do I turn off accelerometer input for my flipside view

    - by user308050
    I have an iPhone 3.1.3 app which has only 2 methods of input in its main view. It has an info button to switch to a flipside view, and the only other input it takes in the main view is accelerometer movement. I want to switch off the accelerometer input when in the flipside view but haven't been able to find out how. I have the main view controller set as an accelerometer delegate, but did not do the same for the flipside view controller, though I suspect that it inherited it from the main view controller. I am really new to xcode and objective c, I have been reading these forums and a couple of developer books, but if anyone has any tips on other good places to look, please let me know.

  • Comparison between Tigase, Openfire and any other open-source XMPP servers

    - by John
    I've been looking at these too, both seem to provide fully functional XMPP servers in Java. I know Tigase is designed in a very modular way, not looked at Openfire in as much detail yet. My intended use would be to create a custom IM-based app, using XMPP for convenience rather than to open my server up to talk to other XMPP servers. I'm trying to evaluate my needs based on the following, roughly in order of importance: Documentation coverage & community How easy to plug in own functionality Licensing/cost - I don't plan to release my code Maturity and stability

  • How do I setup ASP.NET MVC 2 with MySQL?

    - by NovaJoe
    Okay, so I'm cheating and not actually a question, but instead making a flat-out post. I know that goes against the grain of Stack Overflow, but this is too valuable not to share. I'm assuming that you have Visual Studio Professional 2008 and access to an instance of MySQL server. This MAY work with VS2008 Web edition, but not at all sure. If you haven't, install MySQL Connector for .NET (6.2.2.0 at the time of this write-up) Optional: install MySQL GUI Tools If you haven't, install MVC 2 RTM, or better yet, use Microsoft's Web Platform Installer. Create an empty MySQL database. If you don't want to access your application with the MySQL root user account (insecure), create a user account and assign the appropriate privileges (outside the scope of this write-up). Create a new MVC 2 application in Visual Studio In the MVC 2 app, reference MySql.Web.dll. It will either be in your GAC, or in the folder that the MySQL Connector installer put it. Modify the connection strings portion of your web.config: <connectionStrings> <remove name="LocalMySqlServer"/> <add name="MySqlMembershipConnection" connectionString="Data Source=[MySql server host name];user id=[user];password=[password];database=[database name];" providerName="MySql.Data.MySqlClient"/> </connectionStrings> Modify the membership portion of your web.config: <membership defaultProvider="MySqlMembershipProvider"> <providers> <clear/> <add name="MySqlMembershipProvider" type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="MySqlMembershipConnection" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" autogenerateschema="true"/> </providers> </membership> Modify the role manager portion of your web.config: <roleManager enabled="true" defaultProvider="MySqlRoleProvider"> <providers> <clear /> <add connectionStringName="MySqlMembershipConnection" applicationName="/" name="MySqlRoleProvider" type="MySql.Web.Security.MySQLRoleProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" autogenerateschema="true"/> </providers> </roleManager> Modify the profile portion of your web.config: <profile> <providers> <clear/> <add type="MySql.Web.Security.MySQLProfileProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" name="MySqlProfileProvider" applicationName="/" connectionStringName="MySqlMembershipConnection" autogenerateschema="true"/> </providers> </profile> At this point, you ought to be able to run the app and have the default ASP.NET MVC 2 home page come up in your browser. However, it may be a better idea to first run the ASP.NET Web configuration Tool (in Visual Studio top menus: Project - ASP.NET Configuration). Once the tool launches, check out each of the tabs; no errors = all good. The configuration tool Nathan Bridgewater's blog was essential to getting this working. Kudos, Nathan. Look for the "Configuration Tool" heading half way down the page. The public key token on the MySql.web.dll that I've posted here ought not change any time soon. But in case you suspect a bad token string from copying and pasting or whatever, just use the Visual Studio command line to run: "sn -T [Path\to\your.dll]" in order to get the correct public key token. There you have it, ASP.NET MVC 2 running over MySQL. Cheers!

  • Objective-C runtime reflection (objc_msgSend): does it violate the iPhone Developer License Agreemen

    - by GamingHorror
    Does code like this (potentially) violate the iPhone Developer License Agreement? Class clazz = NSClassFromString(@"WNEntity"); id entity = [clazz entityWithImage:@"Icon.png"]; SEL setPositionSelector = NSSelectorFromString(@"setPosition:"); objc_msgSend(entity, setPositionSelector, CGPointMake(200, 100)); I'm working on code that dynamically allocates classes from XML and calls methods on them via objc_msgSend. It's just very convenient constructing my objects that way but it worries me because i have no idea whether this is ok or violates the License by dynamically executing code or maybe even calling private (?) API functions. They wouldn't be documented if they were private, right? Can someone shed some light on this? Have you had an App approved or rejected using code similar to the above? I'm pretty sure that this is ok but i wan't to hear it from someone else! :)

  • wpf toolkit (Feb 2010) datagrid with MVVM - style reveals name of view model on 'spare column'

    - by Andy Clarke
    Hi, I've just updated my app with the latest WPF toolkit and I've now got an issue with my styling. When I bind some data with, for example, two columns to the grid, the spare area at the right shows the name of the ViewModel in the header. I can understand why, because the data grids data context is the ViewModel and I'm defining my header style as follows ... <WpfToolkit:DataGridHeaderBorder <Border BorderBrush="Blue" BorderThickness="0,1,0,0"> <TextBlock Text="{Binding}" Margin="4,0,4,0" /> </Border> </WpfToolkit:DataGridHeaderBorder> Do I now need a separate style for the 'spare column' or something? Can anyone assist please? Cheers, Andy

    - by CStreel
    I'm trying to use Segue to present then dismiss a Popover view a UIBarButtonItem is clicked.

  • Error when starting a tab activity in Android?

    - by ATDeveloper
    I followed the directions verbatim in this Android tutorial, copying/pasting the code from the site to my app. http://developer.android.com/resources/tutorials/views/hello-tabwidget.html However, when I try to run in the Android emulator, I get the error: "The application Hello Tab Widget has stopped unexpectedly. Please try again." I tried debugging by introducing a breakpoint in the first line of the onCreate method, but the error occurs before the breakpoint is even hit. Any idea of what is going wrong, or any other way I can debug this issue? I am using Eclipse.

  • Cannot get NLogViewer to receive msgs from local machine

    - by slolife
    I cannot get NLogViewer to receive msgs from local machine. My machine is Windows 7. I am able to get a remote machine to send NLog messages to my local box and NLogViewer on my local box shows the message fine. But, if I run an app locally, and config NLog to spit messages to my local box, NLogViewer doesn't get the messages. Here's my config: <targets> <target name="viewer" xsi:type="NLogViewer" address="udp://localhost:4050"/> </targets> <rules> <logger name="*" minlevel="Info" writeTo="viewer" /> <rules> Is it Windows 7 security? I have config'd Windows Firewall to allow UDP port 4050 inbound and outbound. My apps are an ASP.NET site and a few windows services.

  • setting enablesReturnKeyAutomatically on UISearchBar

    - by Erik Carlson
    Hi There, I'm writing for iphone OS 3.1.3. I want the search button in the keyboard from my UISearchBar to have the search button enabled all the time. If this was any old UITextField (not a search bar) the property would be enablesReturnKeyAutomatically. I have tried setting this using the example given at http://discussions.apple.com/thread.jspa?messageID=8457910 which suggests: UITextField *searchTextField ; searchTextField = [[searchBar subviews]objectAtIndex:0]; searchTextField.enablesReturnKeyAutomatically = NO ; Should work. unfortunately it crashes: 2010-05-20 08:36:18.284 ARemote[5929:207] *** -[UISearchBarBackground setEnablesReturnKeyAutomatically:]: unrecognized selector sent to instance 0x3b31980 2010-05-20 08:36:18.284 ARemote[5929:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UISearchBarBackground setEnablesReturnKeyAutomatically:]: unrecognized selector sent to instance 0x3b31980' I have also tried ((UITextField *)[(NSArray *)[searchBar subviews] objectAtIndex:0]).enablesReturnKeyAutomatically = NO;</code> Which gives similar results. Any ideas? Cheers Erik

  • Problem with Richfaces running with NGinx proxy

    - by Michael
    Hi, I got a problem with my Richfaces application. I am using it with JSF and GlassFish v.2 on my localhost and combination od dataTable and dataScroller works fine. While moving the app to the VPS running Tomcat but proxied by Nginx server, everything crashes. Exactly the scroller is working, but the dataTable view is not refreshed! I looked at responses with Firebug and figured out, that even on VPS the response contains 2nd page of the dataTable, but it is not shown on the screen. I tried everything - changing page attribute of dataScroller (it was taken from session bean, I changed that to request bean). I also removed page attribute from dataScroller - did not help either. Finally I added my table to reRender attribute of dataScroller - still whichever page I choose I am seeing only the first one. Does anyone even heard about such problem? I am going crazy with this. Best regards, Michael

  • WPF Resource Dictionary in a separate assembly

    - by Gustavo Cavalcanti
    I have resource dictionary files (MenuTemplate.xaml, ButtonTemplate.xaml, etc) that I want to use in multiple separate applications. I could add them to the applications' assemblies, but it's better if I compile these resources in one single assembly and have my applications reference it, right? After the resource assembly is built, how can I reference it in the App.xaml of my applications? Currently I use ResourceDictionary.MergedDictionaries to merge the individual dictionary files. If I have them in an assembly, how can I reference them in xaml? Thanks for your help! Gustavo

  • Convert byte array from Oracle RAW to System.Guid?

    - by Cory McCarty
    My app interacts with both Oracle and SQL Server databases using a custom data access layer written in ADO.NET using DataReaders. Right now I'm having a problem with the conversion between GUIDs (which we use for primary keys) and the Oracle RAW datatype. Inserts into oracle are fine (I just use the ToByteArray() method on System.Guid). The problem is converting back to System.Guid when I load records from the database. Currently, I'm using the byte array I get from ADO.NET to pass into the constructor for System.Guid. This appears to be working, but the Guids that appear in the database do not correspond to the Guids I'm generating in this manner. I can't change the database schema or the query (since it's reused for SQL Server). I need code to convert the byte array from Oracle into the correct Guid.

  • How to structure VB.NET windows forms applications

    - by Jon
    What is the best way to structure a VB.NET windows forms application so that code can be reused and the app can be extended easily. I used to create lots of new forms. This lead to lots of repeated code and forms which did similar things. Now, for forms which do similar jobs, such as view/edit/delete items from a specific db table, I create a form with the required controls, have the form create an instance of a class with params such as a collection of the controls and a string containing the db table name. Then the individual controls call functions of the class. Advanced forms will inherit and extend this basic form class. 1) Has there already been work done in this area? 2) Are there books / articles available which discuss the options available on this topic? Thanks!

  • Rails cookie session sharing and "www.example.com" or "example.com" problem

    - by Rafael Mueller
    When people access my app on www.example.com and log in, they get a cookie. I'm using the cookie option to store session on Rails. Accessing example.com (without the www), they must log in again, because Firefox does not recognize the previous session. So, what do you think is the best way to avoid this? I guess I will use a small .htaccess rule (Apache + Passenger) like this: RewriteEngine on RewriteCond %{HTTP_HOST} ^example\.com RewriteRule ^(.*)$ http://www.example.com/$1 [R=permanent,L] Do you guys think that is a good solution?

  • Facebook Application Tab URL

    - by Paul
    I have a facebook application that can be added to fan pages as a tab. The application requires that users are authenticated in order to use it. This can be accomplished by using requirelogin=1 in a link which is visible only to users who have NOT added the application. This part works fine. However, after the user has given my application permission from the dhtml pop up that requirelogin opens, I want the tab to reload. In order to do that, I need the full URL to be included in the link as follows: <a href="http://www.facebook.com/pages/PAGE_NAME/PAGE_ID?v=app_APP_ID" requirelogin=1>Authorize</a> I cannot figure out how to get the full url or, at least, the PAGE_NAME to build this url dynamically. Seems like the app should be able to know where it is without any special permissions.
