  • How do I implement page authorizaton in ASP.NET using a SQL store instead of web.config?

    - by drachenstern
    For instance, the way we're doing it now is like thus: (in the web.config) <location path="somePath"> <system.web> <authorization> <allow roles="approvedRoles"/> <deny users="*"/> </authorization> </system.web> </location> And what I would like to do instead is to store this information in SQL somewhere so that we can manipulate the information more easily. But we want to keep the same functionality that having the information in web.config provides, just like we can use a SqlRoleProvider instead of hardcoding roles in the app. So in other words, if a user currently tries to goto "somePath" and they're not a member of "approvedRoles" then they get redirected back to default.aspx, and if they are a member of "approvedRoles" then they get the page. I want to do the same thing, but without using web.config as the authorization mechanism. So what I'm NOT asking is how do I go about defining roles, or how do I handle logging in to the database, but specifically how do I store the above information in SQL instead of web.config. Actually, I'll take "anywhere but web.config" for now. Any ideas? Is this possible using a "Provider" class? I'm just looking for pointers on what to inherit and maybe some technet documentation. In this regard my googlefoo is lacking since I don't really know where to point. Am I really only looking for AzMan? Is this location-authorization-via-SQL already defined in the default aspnetdb somewhere and I'm missing it? For that matter, has this question already been asked on SO and I've missed it? What would you google?

  • python NameError: name '<anything>' is not defined (but it is!)

    - by BenjaminGolder
    Note: Solved. It turned out that I was importing a previous version of the same module. It is easy to find similar topics on StackOverflow, where someone ran into a NameError. But most of the questions deal with specific modules and the solution is often to update the module. In my case, I am trying to import a function from a module that I wrote myself. The module is named InfraPy, and it is definitely on sys.path. One particular function (called listToText) in InfraPy returns a NameError, but only when I try to import it into another script. Inside InfraPy, under if __name__=='__main__':, the listToText function works just fine. From InfraPy I can import other functions with no problems. Including from InfraPy import * in my script does not return any errors until I try to use the listToText function. How can this occur? How can importing one particular function return a NameError, while importing all the other functions in the same module works fine? Using python 2.6 on MacOSX 10.6, also encountered the same error running the script on Windows 7, using IronPython 2.6 for .NET 4.0 Thanks. If there are other details you think would be helpful in solving this, I'd be happy to provide them. As requested, here is the function definition inside of InfraPy: def listToText(inputList, folder=None, outputName='list.txt'): ''' Creates a text file from a list (with each list item on a separate line). May be placed in any given folder, but will otherwise be created in the working directory of the python interpreter. ''' fname = outputName if folder != None: fname = folder+'/'+fname f = open(fname, 'w') for file in inputList: f.write(file+'\n') f.close() This function is defined above and outside of if __name__=='__main__': I've tried moving InfraPy around in relation to the script. The most baffling situation is that when InfraPy is in the same folder as the script, and I import using from InfraPy import listToText, I receive this error: NameError: name listToText is not defined. Again, the other functions import fine, they are all defined outside of if __name__=='__main__': in InfraPy.

  • How to build Android for Samsung Galaxy Note

    - by Tr?n Ð?i
    I'd like to modify and build my own Android for my Samsung Galaxy Note I've downloaded Android 4.1.2 from http://source.android.com and Samsung open source for my Samsung Galaxy Note. After extract Samsung open source, I get 2 folders: Kernel and Platform, and 2 README text file README_Kernel.txt 1. How to Build - get Toolchain From android git server , codesourcery and etc .. - arm-eabi-4.6 - edit build_kernel.sh edit "CROSS_COMPILE" to right toolchain path(You downloaded). EX) CROSS_COMPILE= $(android platform directory you download)/android/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi- Ex) CROSS_COMPILE=/usr/local/toolchain/arm-eabi-4.6/bin/arm-eabi- // check the location of toolchain - execute Kernel script $ ./build_kernel.sh 2. Output files - Kernel : arch/arm/boot/zImage - module : drivers/*/*.ko 3. How to Clean $ make clean README_Platform.txt [Step to build] 1. Get android open source. : version info - Android 4.1 ( Download site : http://source.android.com ) 2. Copy module that you want to build - to original android open source If same module exist in android open source, you should replace it. (no overwrite) # It is possible to build all modules at once. 3. You should add module name to 'PRODUCT_PACKAGES' in 'build\target\product\core.mk' as following case. case 1) bluetooth : should add 'audio.a2dp.default' to PRODUCT_PACKAGES case 2) e2fsprog : should add 'e2fsck' to PRODUCT_PACKAGES case 3) libexifa : should add 'libexifa' to PRODUCT_PACKAGES case 4) libjpega : should add 'libjpega' to PRODUCT_PACKAGES case 5) KeyUtils : should add 'libkeyutils' to PRODUCT_PACKAGES case 6) bluetoothtest\bcm_dut : should add 'bcm_dut' to PRODUCT_PACKAGES ex.) [build\target\product\core.mk] - add all module name for case 1 ~ 6 at once PRODUCT_PACKAGES += \ e2fsck \ libexifa \ libjpega \ libkeyutils \ bcm_dut \ audio.a2dp.default 4. In case of 'bluetooth', you should add following text in 'build\target\board\generic\BoardConfig.mk' BOARD_HAVE_BLUETOOTH := true BOARD_HAVE_BLUETOOTH_BCM := true 5. excute build command ./build.sh user What I need to do after followed 2 above files

  • Java EE6 App + EJB in Glassfish 3.0/Netbeans 6.8?

    - by egbokul
    Has anyone got this configuration working? Latest Netbeans, latest Glassfish, I created an EJB project, also an EE Application. The EJB in itself builds & deploys to Glassfish OK. Now when I want to reference the EJB, I have to add the EJB jar to the EE Application path, if I don't do this the code does not compile. But, the EJB jar gets packaged in the App jar and as a result when I try to deploy the app to Glassfish it says: "java.lang.IllegalArgumentException: Sniffers with type [ejb] and type [appclient] should not claim the archive at the same time. Please check the packaging of your archive" How do I tell Netbeans NOT TO package the EJB in the App jar? Or is the problem somewhere else? btw. if I remove the EJB manually from the JAR then the app deploys successfully (with asadmin deploy), but when I try to run it with appclient, I get a NullPointerException. Surely there must be a solution to this, I thought Netbeans was for web application development after all...

  • Unregistering COM dll with a C# Setup Project

    - by lb
    Hi All. I've been stuck on this one for a while. I'll try explain in the simplest terms and at the best of my knowledge. I will honour any help. I've got a C# project which uses a VB6 compiled ActiveX DLL that I'm constantly updating. I compile the setup project, send it to the client and they run the setup. When building the updated setup project, I would increase the 'Version' of the setup project so it wouldn't bother with 'Another version is already installed'. What started happening after a few updates I began to notice the DLL would not be updated to the new version in the installer. The client computer had the original DLL both installed and registered. First symptom: method not found exceptions from the client C# code. This is not a shared DLL and only this application needs it. I've noticed that when uninstalling the application (through the usual procedure) the DLL is also not removed from the application folder although I would set this file's property 'Permanent' to false. The registration entries in the registry are mantained also. I do update in VS6.0 the version of the DLL (usually increase the build number) before building it. Then in VS2008, I remove it from the References, and add it again from the 'Browse tab', without re-registering it on my dev machine and adding it from the COM tab. I've thought of these options. Custom step in Setup project to regsvr32.exe /u 'hardcoded path of my dll' at uninstall (ugly) Somehow find out how the 'Isolate' property can work for me without registering Find out how to execute setup project 'Conditions' that would actually check the version of the library and to update the file accordingly at every install) Any help would be incredibly welcome.

  • MVVM- How can I bind to a property, which is not a DependancyProperty?

    - by highone
    I have found this question http://stackoverflow.com/questions/2245928/mvvm-and-the-textboxs-selectedtext-property. However, I am having trouble getting the solution given to work. This is my non-working code: View: SelectedText and Text are just string properties from my ViewModel. <TextBox Text="{Binding Path=Text, UpdateSourceTrigger=PropertyChanged}" Height="155" HorizontalAlignment="Left" Margin="68,31,0,0" Name="textBox1" VerticalAlignment="Top" Width="264" AcceptsReturn="True" AcceptsTab="True" local:TextBoxHelper.SelectedText="{Binding SelectedText, UpdateSourceTrigger=PropertyChanged}" /> <TextBox Text="{Binding SelectedText, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}" Height="154" HorizontalAlignment="Left" Margin="82,287,0,0" Name="textBox2" VerticalAlignment="Top" Width="239" /> TextBoxHelper public static class TextBoxHelper { #region "Selected Text" public static string GetSelectedText(DependencyObject obj) { return (string)obj.GetValue(SelectedTextProperty); } public static void SetSelectedText(DependencyObject obj, string value) { obj.SetValue(SelectedTextProperty, value); } // Using a DependencyProperty as the backing store for SelectedText. This enables animation, styling, binding, etc... public static readonly DependencyProperty SelectedTextProperty = DependencyProperty.RegisterAttached( "SelectedText", typeof(string), typeof(TextBoxHelper), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, SelectedTextChanged)); private static void SelectedTextChanged(DependencyObject obj, DependencyPropertyChangedEventArgs e) { TextBox tb = obj as TextBox; if (tb != null) { if (e.OldValue == null && e.NewValue != null) { tb.SelectionChanged += tb_SelectionChanged; } else if (e.OldValue != null && e.NewValue == null) { tb.SelectionChanged -= tb_SelectionChanged; } string newValue = e.NewValue as string; if (newValue != null && newValue != tb.SelectedText) { tb.SelectedText = newValue as string; } } } static void tb_SelectionChanged(object sender, RoutedEventArgs e) { TextBox tb = sender as TextBox; if (tb != null) { SetSelectedText(tb, tb.SelectedText); } } #endregion } What am I doing wrong?

  • WPF: Invert OpacityMask

    - by Meleak
    Consider the following piece of Xaml <Grid Background="Blue"> <Border Width="100" Height="60" BorderBrush="Black" BorderThickness="2"> <Border Background="Red"> <Border.OpacityMask> <VisualBrush> <VisualBrush.Visual> <TextBlock Text="Text" Foreground="#FF000000" Background="#00000000"/> </VisualBrush.Visual> </VisualBrush> </Border.OpacityMask> </Border> </Border> </Grid> It will look like this because of the OpacityMask whos only non-transparent part is the Foreground of the TextBlock. Now if I switch the Colors for Foreground and Background in the TextBlock like this <TextBlock Text="Text" Foreground="#00000000" Background="#FF000000"/> I get this because the even though the Foreground is transparent the Background behind it is not, resulting in a useless OpacityMask :) Is there anyway I can get this? Basically an inverted OpacityMask The reason I'm asking this is because of the answer I made in this question, using the approach from this link. Even though it works, it feels very "hacky". Am I missing some other way to do this here? Update To clarify, even though my example is about a TextBlock, it could be anything. Ellipse/Image/Path etc. The feature I'm after is "Invert OpacityMask"

  • nginx with passenger

    - by Luc
    Hello, I'm trying to move from Apache + Passenger to Nginx + passenger on my Ubuntu Lucid Lynx box. When I install passenger, sudo gem install passenger and cd /var/lib/gems/1.9.1/gems/passenger-2.2.14/bin sudo ./passenger-install-nginx-module everything is fine (no error). Nginx is downloaded / compiled and installed at the same time (when selecting the first option during passenger installation). By default it is installed in /opt/nginx. I end up with the configuration file /opt/nginx/conf/nginx.conf (this conf file was automatically updated with passenger config). The thing I do not understand is that I also have the configuration file /etc/nginx/nginx.conf... what is the purpose of this one when it seems that the conf file in /opt/... is the main one ? When I run /etc/init.d/nginx start, it starts correclty saying that /etc/nginx/nginx.conf is ok... Does it mean that it does not check the other conf file ? I have updated /etc/init.d/nginx script and add /opt/nginx/sbin at the beginning of the PATH and it seems the correct conf file is taken into account. It seems like I have 2 nginx installations where I only relied on passenger to install it... Thanks a lot for your help, I am kind of lost here :) Luc

  • Windows Azure ASP.NET MVC Role behaves strangely when redirecting from HTTP to HTTPS

    - by Rinat Abdullin
    Subj. I've got an ASP.NET 2 MVC Worker Role Application, that does not differ much from the default template. When attempting redirect from HTTP to HTTPS (this happens when we access constroller secured by the usual RequireSSL attribute implementation) we get blank page with "Bad Request" message. IntelliTrace shows this: Thrown: "The file '/Views/Home/LogOnUserControl.aspx' does not exist." (System.Web.HttpException) Call stack is really short: [External Code] App_Web_vfahw7gz.dll!ASP.views_shared_site_master.__Render__control1(System.Web.UI.HtmlTextWriter __w = {unknown}, System.Web.UI.Control parameterContainer = {unknown}) [External Code] App_Web_bsbqxr44.dll!ASP.views_home_index_aspx.ProcessRequest(System.Web.HttpContext context = {unknown}) [External Code] User control reference is the usual one in /Views/Shared/Site.Master: <div id="logindisplay"> <% Html.RenderPartial("LogOnUserControl"); %> </div> And partial view LogOnUserControl.ashx is located in Views/Shared (and it is ASHX, not ASPX). Problem shows up, when we try to access site pages, that require auth and redirect. These pages are secured by RequireSSL attribute (Redirect == true): [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = false)] public sealed class RequireSslAttribute : FilterAttribute, IAuthorizationFilter { public bool Redirect { get; set; } // Methods public void OnAuthorization(AuthorizationContext filterContext) { // this get's messy, when we are running custom ports // within the local dev fabric. // hence we disable code in the debug #if !DEBUG if (filterContext == null) { throw new ArgumentNullException("filterContext"); } if (filterContext.HttpContext.Request.IsSecureConnection) return; var canRedirect = string.Equals(filterContext.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase); if (canRedirect && Redirect) { var builder = new UriBuilder { Scheme = "https", Host = filterContext.HttpContext.Request.Url.Host, Path = filterContext.HttpContext.Request.RawUrl }; filterContext.Result = new RedirectResult(builder.ToString()); } else { throw new HttpException(0x193, "Access forbidden. The requested resource requires an SSL connection."); } #endif } } Obviously we compile in RELEASE for this case. Does anybody have any idea, what could cause this strange exception and how to get rid of it?

  • Properly using Log4r in Ruby Application

    - by Spencer
    I must really be missing something obvious, but I'm having trouble with general use of Log4r in my Ruby application. I am able to log without issue, but the overhead seems clunky the way I have it setup. I'm basically passing the full path to a filename to log in each class in my application. The ruby script that is called pulls the log file from one of the arguments in ARGV which is then passed around and set in each class that I call in ruby. In each class I use the patternFormatter to insert the class/file name into the log statement. Is there a better way to make this work? It feels like no matter what I think of will require something to be passed to each class in my ruby application. I could set the log file in a yaml configuration file instead, but then I would be passing around the configuration file to each class as well. Any advice? If this doesn't make sense I could try and post some more specific code samples to further explain what I mean. Thanks!

  • Recursive Perl detail need help

    - by Catarrunas
    Hi everybody, i think this is a simple problem, but i'm stuck with it for some time now! I need a fresh pair of eyes on this. The thing is i have this code in perl: #!c:/Perl/bin/perl use CGI qw/param/; use URI::Escape; print "Content-type: text/html\n\n"; my $directory = param ('directory'); $directory = uri_unescape ($directory); my @contents; readDir($directory); foreach (@contents) { print "$_\n"; } #------------------------------------------------------------------------ sub readDir(){ my $dir = shift; opendir(DIR, $dir) or die $!; while (my $file = readdir(DIR)) { next if ($file =~ m/^\./); if(-d $dir.$file) { #print $dir.$file. " ----- DIR\n"; readDir($dir.$file); } push @contents, ($dir . $file); } closedir(DIR); } I've tried to make it recursive. I need to have all the files of all of the directories and subdirectories, with the full path, so that i can open the files in the future. But my output only returns the files in the current directory and the files in the first directory that it finds. If i have 3 folders inside the directory it only shows the first one. Ex. of cmd call: "perl readDir.pl directory=C:/PerlTest/" Thanks

  • Intelligent web features, algorithms (people you may follow, similar to you ...)

    - by hilal
    I have 3 main questions about the algorithms in intelligent web (web 2.0) Here the book I'm reading http://www.amazon.com/Algorithms-Intelligent-Web-Haralambos-Marmanis/dp/1933988665 and I want to learn the algorithms in deeper 1. People You may follow (Twitter) How can one determine the nearest result to my requests ? Data mining? which algorithms? 2. How you’re connected feature (Linkedin) Simply algorithm works like that. It draws the path between two nodes let say between Me and the other person is C. Me - A, B - A connections - C . It is not any brute force algorithms or any other like graph algorithms :) 3. Similar to you (Twitter, Facebook) This algorithms is similar to 1. Does it simply work the max(count) friend in common (facebook) or the max(count) follower in Twitter? or any other algorithms they implement? I think the second part is true because running the loop dict{count, person} for person in contacts: dict.add(count(common(person))) return dict(max) is a silly act in every refreshing page. 4. Did you mean (Google) I know that they may implement it with phonetic algorithm http://en.wikipedia.org/wiki/Phonetic_algorithm simply soundex http://en.wikipedia.org/wiki/Soundex and here is the Google VP of Engineering and CIO Douglas Merrill speak http://www.youtube.com/watch?v=syKY8CrHkck#t=22m03s What about first 3 questions?

  • How to configure oracle instantclient for mono?

    - by funwithcoding
    Mono is really awesome. Some of our applications worked in linux out of the box even without recompiling the binary. However I am having tough time to configure oracle instantclient to use it with mono. I installed instantclient on a CentOS VM(by installing instantclient rpm) but however I did not find TNSNAMES.ORA anywhere. I searched for oracle and I found the following path contains the oracle libraries. [root@bagvapp rupert]# ll /usr/lib/oracle/11.2/client/lib/ total 143280 -rw-r--r-- 1 root root 7456 Aug 14 2009 cobsqlintf.o -rw-r--r-- 1 root root 342 Aug 14 2009 glogin.sql lrwxrwxrwx 1 root root 17 Mar 9 06:52 libclntsh.so -> libclntsh.so.11.1 -rw-r--r-- 1 root root 40088477 Aug 14 2009 libclntsh.so.11.1 -rw-r--r-- 1 root root 6986848 Aug 14 2009 libnnz11.so lrwxrwxrwx 1 root root 15 Mar 9 06:52 libocci.so -> libocci.so.11.1 -rw-r--r-- 1 root root 1879549 Aug 14 2009 libocci.so.11.1 -rw-r--r-- 1 root root 89377610 Aug 14 2009 libociei.so -rw-r--r-- 1 root root 152304 Aug 14 2009 libocijdbc11.so -rw-r--r-- 1 root root 1501651 Aug 14 2009 libsqlplusic.so -rw-r--r-- 1 root root 1218075 Aug 14 2009 libsqlplus.so -rw-r--r-- 1 root root 777979 Aug 14 2009 libsqora.so.11.1 -rw-r--r-- 1 root root 1996228 Aug 14 2009 ojdbc5.jar -rw-r--r-- 1 root root 2111220 Aug 14 2009 ojdbc6.jar -rw-r--r-- 1 root root 298388 Aug 14 2009 ottclasses.zip drwxr-xr-x 3 root root 4096 Mar 9 06:52 precomp -rw-r--r-- 1 root root 37807 Aug 14 2009 xstreams.jar no TNSPING available, no TNSNAMES.ORA, Now how to configure the mono to use this as the oracle client? and how to specify oracle database in app.config connection string section? Though mono is a powerful framework, seems like it is having problems like linux does, all the documentation is only available in mailing lists and whatever is available on official site is either outdated or not clear for normal user. Hope things will change soon and Mono will THE programming framework for linux.

  • Problems referencing build output from TFS Build and Visual Studio

    - by pmdarrow
    Here's what I'm trying to do: I have two solutions - one for my main application and its associated projects and another for my database (VS .dbproj) and its associated projects. What I'd like to do is include the output from the database project (a .dbschema and some SQL scripts) in my WiX installer (which exists in the main application solution.) This involves having TFS build the DB solution immediately before the main application solution. I've got that part working properly, but I'm having trouble referencing the output of the DB solution from my installer. I'm using relative paths to reference the DB project output in my WiX installer (e.g. <?define DBProjectOutputDir = "..\..\MyDatabaseSolution\MyDatabaseProject\sql\"?>) which works fine locally, but fails when building via TFS build. This is because TFS Build apparently changes the output dir of each project to one common location. Instead of the path to my database project being ..\..\MyDatabaseSolution\MyDatabaseProject\sql\ like it is when building locally, it gets set to something like ..\..\..\Binaries\Release\. How can I get around this and have a consistent output location to reference from my installer project? I'm using TFS 2005 and VS 2008.

  • Unit Testing Error - The unit test adapter failed to connect to the data source or to read the data

    - by michael.lukatchik
    I'm using VSTS 2K8 and I've set up a Unit Test Project. In it, I have a test class with a method that does a simple assertion. I'm using an Excel 2007 spreadsheet as my data source. My test method looks like this: [DataSource("System.Data.Odbc", "Dsn=Excel Files;dbq=|DataDirectory|\\MyTestData.xlsx;defaultdir=C:\\TestData;driverid=1046;maxbuffersize=2048;pagetimeout=5", "Sheet1", DataAccessMethod.Sequential)] [DeploymentItem("MyTestData.xlsx")] [TestMethod()] public void State_Value_Is_Set() { string expected = "MD"; string actual = TestContext.DataRow["State"] as string; Assert.AreEqual(expected, actual); } As indicated in the method decoration attributes, my Excel spreadsheet is on my local C:/ Drive. In it, the sheet where all of my data is located is named "Sheet1". I've copied the Excel spreadsheet into my project and I've set its Build Action = "Content" and I've set its Copy to Output Directory = "Copy if Newer". When trying to run this simple unit test, I receive the following error: The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library. Error details: ERROR [42S02] [Microsoft][ODBC Excel Driver] The Microsoft Office Access database engine could not find the object 'Sheet1'. Make sure the object exists and that you spell its name and the path name correctly. I've verified that the sheet name is spelled correctly (i.e. Sheet1) and I've verified that my data sources are set correctly. Web searches haven't turned up much at all. And I'm totally stumped. All help or input is appreciated!!!!

  • Documentation and Build system for Mono/C#

    - by dcolish
    I'm starting out on a new project and a team member has decided to use C# as the implementation language. I don't have a lot of experience in C#, but a brief reading shows that it's very capable of being a complete cross-platform vm. Beyond the language, I've been having trouble selecting tools and workflows for managing the code as the project grows. It should be fairly small (<10K lines) but I would like to have the ability to generate documentation as the project grows, manage any external dependencies that we decide to use, and automate builds and testing. I am wondering what tools are commonly used or considered best practices for this language. I am mainly concerned with how would a build system potentially work on *nix as well as windows? Are there C# specific tools or is Make more common? In addition, I'd like to use a dvcs, but it doesn't look like Visual Studio and MonoDevelop support the same ones. What's the common vcs of choice for C#? For testing sort of Unit testing is available for C#/Mono? Finally, I know that there are good doc generators, but with the question of the build system, I would really like to have that just be a single step in the build similar to how testing is a step. Normally I'd automate with Hudson, but I am wondering if there is something more specific to the platform. Overall, I'd love to see a solution that provides a decent workflow on both windows and *nix without a heavy admin burden. I am pretty sure this is the holy grail of project management, so anything that puts me on that path is awesome.

  • Multiple Application Support Directories for iPhone Simulator?

    - by Alex G
    I am developing an iPhone app with someone else. The app works fine for me, but he is running into a bug. We think this bug is related to the fact that he is getting multiple Application directories for this same app. In my ~/Library/Application Support/iPhone Simulator/User/Applications, I only have one folder at all times. He says that he will get 3 or 4 directories when he is only working on this one app. We think this is our problem because our bug has to do with displaying images that are stored in the app's Documents folder. Does anyone know why he is ending up with multiple directories or how to stop it? Edit: Here is the code for writing the image to a file: NSData *image = [NSData dataWithContentsOfURL:[NSURL URLWithString:[currentArticle articleImage]]]; NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *imagePath = [array objectAtIndex:0]; NSFileManager *NSFM = [NSFileManager defaultManager]; BOOL isDir = YES; if(![NSFM fileExistsAtPath:imagePath isDirectory:&isDir]) if(![NSFM createDirectoryAtPath:imagePath attributes:nil]) NSLog(@"error"); imagePath = [imagePath stringByAppendingFormat:@"/images"]; if(![NSFM fileExistsAtPath:imagePath isDirectory:&isDir]) if(![NSFM createDirectoryAtPath:imagePath attributes:nil]) NSLog(@"error"); imagePath = [imagePath stringByAppendingFormat:@"/%@.jpg", [currentArticle uniqueID]]; [image writeToFile:imagePath atomically:NO]; And here is the code for getting the path when I need the image: - (NSString *)imagePath { NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *imagePath = [array objectAtIndex:0]; return [imagePath stringByAppendingFormat:@"/images/%@.jpg", [self uniqueID]]; } The app works great for me, but my partner says that the images don't show up intermittently, and he notices that he gets multiple directories in his Applications folder.

  • Enable cross app redirects

    - by Gogster
    Hi all, We have load balancing set up on out two web server, however, a few users are being asked to login when they are being re-directed to a particular server to upload a document (we are trying to keep all uploaded documents on one server only), here is the code from web.config: <authentication mode="Forms"> <forms name="EAAAuthCookie" loginUrl="/login" defaultUrl="/members/home" protection="All" path="/" timeout="60000" slidingExpiration="true" enableCrossAppRedirects="true" /> </authentication> <machineKey decryption="AES" validation="SHA1" decryptionKey="7B4EC5B0C83631DF25D5B179EDDBF91B1C175B81C6F52102267D3D097FBF272A" validationKey="7D1F50788629CC342EE4985D85DE3D14F10654695912C0FFD439F54BED64F76A57A2D5E8180BC6FF052E0385C30558F5527D6C197C577A7F32DD8FF1CAC9F794" /> Here is the transfer code to the upload form: $('#addReport').click(function() { if ($.cookie('TransferURL') != '') { $("#iframeUploadReport").attr('src', $.cookie('TransferURL')); }; $('#overlay').fadeIn('slow'); }); <script type="text/C#" runat="server"> void Page_Load() { string cookieName = FormsAuthentication.FormsCookieName; string userName = Request.Cookies["HiddenUsername"].ToString(); string cookieValue = FormsAuthentication.GetAuthCookie(userName, false).Value; Response.Cookies["TransferURL"].Value = "http://eaa.cms.necinteractive.net/members/media-upload" + String.Format("?{0}={1}", cookieName, cookieValue); } </script> <iframe id="iframeUploadReport" src="http://eaa.cms.necinteractive.net/members/media-upload" width="500px" height="336px" frameborder="0" scrolling="no"></iframe> Can you see any obvious step we are missing? Thanks

  • TFS and Forms Authentication

    - by George
    I don't know squat about TFS, other than as a user who has performed simple check in/outs. I just installed it locally and would like to do joint development with a friend. I was having trouble making my TFS web site on port 8080 visible (the whole scoop is here if your interested) and I wonder if it could be related to the fact that TFS is probably using Windows Authentication to identify the user. Can TFS be set up to use forms authentication? We probably need to set up a VPN, though that's a learning curve too. To use TFS, do our machines have to belong to a domain? We're not admin types, though he is better than me, though I would be interested in any feedback or advice on which path is likely to pan out the best. I already got AxoSoft OneTime working in this type of an environment and it suits us well, but I am tempted at all the bells & whistles with TFS and the ability to tie tracked bug items to code changes. As far as finding a good way to share code, do sites like SourceForge allow one to keep code secure among members only?

  • Can't create new xib files in Xcode projects

    - by Reed Olsen
    This one is a doozy... My buddy just downloaded the iPhone SDK on his Snow Leopard MacBook Pro. No matter what kind of project he creates (Window Based, View Based, etc...,) he can't create or use his own xib files. The project will compile and run fine until he adds a new xib file. Here are some symptoms: When he selects a pre-generated xib in Xcode (such as MainWindow.xib), no preview is shown on the right hand side. Double clicking on this file will open it in interface builder (This is correct behavior). When he selects his own custom xib, the preview pane displays the XML content of the xib. Double clicking on his custom xib opens up the XML file in Xcode - as if it were a standard code file (This is jacked up). Opening his custom xib from finder opens it in Interface Builder. When building the application, the build warning says something to the effect of "Warning: No rule to process file /path/to/CustomXib of type sourcecode.xib for architecture i386" At runtime he gets the error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] was unable to load a nib named "MyCustomXib"' We've uninstalled Xcode from the command line and reinstalled. I've verified that it's the right version for his machine. I'm stumped!
