• Find directory on different server C#

  - by rainhider

  I have a website on Server A and it needs to find a directory on Server B. On my aspx page, I have: <mb:FileSystemDataSource ID="fileSystemDataSource" runat="server" RootPath="\\servername\Folder\Subfolder" FoldersOnly="true" /> mb is assembly name alias. On my aspx.cs page, I have: protected void Page_Load(object sender, EventArgs e) { DataTable gridviewSource = DisplayFilesInGridView(); DataRow gridviewRow; //sets the server path so it does not default to current server string ServerPath = System.IO.Path.Combine( "//", this.fileSystemDataSource.RootPath); //Get All Folders Or Directories and add in table DirectoryInfo directory = new DirectoryInfo(Server.MapPath(ServerPath)); DirectoryInfo[] subDirectories = directory.GetDirectories(); } Well, it throws an error on the Server.MapPath because it cannot find the server. I am connected to the network. I looked at IIS, and I am pretty sure that is not the problem. If so, I would really need specifics. Any help would be appreciated.

• How to have multiple paths display URL as root

  - by Verdi Erel Ergün

  I want users#new and tasks#index to display as the root path URL, i.e. / When a user logs in on the path users#new (set as root) they are redirected to tasks#index and URL does not change. Can this be done in the routes.rb file? This is my routes.rb file: Todo::Application.routes.draw do resources :sessions resources :subscriptions resources :users resources :tasks do collection do post :sort end end root :to => "users#new" match "sessions#new" => "tasks#index" match "sessions#" => "tasks#index"

  Hi, I have a dump created from StarTeam 2008 R 2 (10.4.7.-64) using svn importer 1.1-M8. But when I am trying to import the dump its giving me error: * adding path : tags/Test/GH/13_Environment/Process/Capgemini EN Template - Business Case.doc ...svnadmin: File already exists: filesystem 'help\db', transaction '2-2', path 'tags/Test/GH/13_Environment/Process/Capgemini EN Template - Business Case.doc' I can see from the svn admin load o/p that the file has been added already. May be the dump created by SVN Importer is not correct. Can anyone guide me how to solve this ?

• Use a "User Macro" in .vcproj RelativePath

  - by Tom Leys

  Inside .vcproj files There is a list of all source files in your project. How can we use a macro to specify the path to a source file? If we do this: <File RelativePath="$(Lib3rdParty)\Qt\qtwinmigrate-2.5-commercial\src\qmfcapp.cpp"> </File> The compiler cannot find the folder: qmfcapp.cpp c1xx : fatal error C1083: Cannot open source file: '.\$(lib3rdparty)\qt\qtwinmigrate- 2.5-commercial\src\qmfcapp.cpp': No such file or directory As you can see, our project compiles in several source files from QT. QT lives inside a folder of external libraries, and we don't want hardcode the path from our project to that folder (we have a very large solution)

• Playing audio from a wav file in iPhone SpeakHere example

  - by Mo

  I'm working with the iPhone SpeakHere example, and I would like to be able to play audio from either the mic (as in the example) or from a wav file. I have working code to play from a particular wav file, which looks like this: NSString *path = [[NSBundle mainBundle] pathForResource:@"basketBall" ofType:@"wav"]; AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio play]; So I'm fine with actually getting the wav to play in the application (I can hook it up to a button, etc.) but I would like it to also behave the same way pushing the "Play" button does after recorded speech, in that it should be connected to the same visualization (which I have modified quite a bit, but essentially shows the current volume, among other things). Thanks for your help!

• linq NullReferenceException while checking for null reference

  - by Odrade

  I have the following LINQ query: List<FileInputItem> inputList = GetInputList(); var results = from FileInputItem f in inputList where ( Path.GetDirectoryName(f.Folder).ToLower().Trim() == somePath || Path.GetDirectoryName(f.Folder).ToLower().Trim() == someOtherPath ) && f.Expression == null select f; Every time this query is executed, it generates a NullReferenceException. If I remove the condition f.Expression == null or change it to f.Expression != null, the query executes normally (giving the wrong results, of course). The relevant bits of FileInputItem look like this: [Serializable] public class FileInputItem { [XmlElement("Folder")] public string Folder { get; set; } [XmlElement("Expression")] public string Expression { get; set; } /*SNIP. Irrelevant properties */ } I'm new to LINQ to objects, so I'm probably missing something fundamental here. What's the deal?

• Core Data deleteObject: sets attributes to nil

  - by SG1

  I am implementing an undo/redo mechanism in my app. This works fine for lots of cases. However, I can't undo past deleteObject:. the object is correctly saved in the undo queue, and I get it back and reinsterted into the Core Data stack just fine when calling undo. The problem is that all it's attributes are getting set to nil when I delete it. I have an entity "Canvas" with a to-many relationship called "graphics" to a "Graphic" entity, which has its inverse set to "canvas". Deleting a Graphic, then inserting it back, doesn't work. Here's the code (the redo method is basically the same): - (void)deleteGraphic:(id)aGraphic { //NSLog(@"undo drawing"); //Prepare the undo/redo [self.undoManager beginUndoGrouping]; [self.undoManager setActionName:@"Delete Graphic"]; [[self.detailItem valueForKey:@"graphics"] removeObject:aGraphic]; [[self managedObjectContext] deleteObject:aGraphic]; //End undo/redo [self.undoManager registerUndoWithTarget:self selector:@selector(insertGraphic:) object:aGraphic]; [self.undoManager endUndoGrouping]; NSLog(@"graphics are %@", [self sortedGraphics]); //Update drawing [self.quartzView setNeedsDisplay]; } and here's the wierdness: Before delete: graphics are ( <NSManagedObject: 0x1cc3f0> (entity: Graphic; id: 0x1c05f0 <x-coredata:///Graphic/t840FE8AD-F2E7-4214-822F-7994FF93D4754> ; data: { canvas = 0x162b70 <x-coredata://A919979E-75AD-474D-9561-E0E8F3388718/Canvas/p20>; content = <62706c69 73743030 d4010203 04050609 0a582476 65727369 6f6e5424 746f7059 24617263 68697665 7258246f 626a6563 7473>; frameRect = nil; label = nil; order = 1; path = "(...not nil..)"; traits = "(...not nil..)"; type = Path; }) After redo: graphics are ( <NSManagedObject: 0x1cc3f0> (entity: Graphic; id: 0x1c05f0 <x-coredata:///Graphic/t840FE8AD-F2E7-4214-822F-7994FF93D4754> ; data: { canvas = nil; content = nil; frameRect = nil; label = nil; order = 0; path = nil; traits = nil; type = nil; }), You can see it's the same object, just totally bleached by Core Data. The relationship delete rouls apparently have nothing to do with it as I've set them to "No Action" in a test.

• How to make script paths inside user control independent of page hierarchy.

  - by Rohit

  My website is organized in the following folder structure Root Pages CustomerManagement DepartMentManagement Script UserControls Now i have a user control inside userControl Folder. I have to use a external js file. So i use it this way <script type="text/javascript" language="javascript" src="../Script/slider.js"></script> My understanding is that since both are under root so i have used a single .. Now what happens is that when this usercontrol is used inside DepartMentManagement it checks for script folder inside CustomerManagement as .. refers to one hierarchy above and script file is not found.Even using a ~ doesnot work. I want to make this script path independent of the path where this control is used. I don't want to move script reference code to the page as control requires script mot page.Please tell me how to achieve this.

• How can I read JSON file from disk and store to array in Swift

  - by Ezekiel Elin

  I want to read a file from Disk in a swift file. It can be a relative or direct path, that doesn't matter. How can I do that? I've been playing with something like this let classesData = NSData .dataWithContentsOfMappedFile("path/to/classes.json"); And it finds the file (i.e. doesn't return nil) but I don't know how to manipulate and convert to JSON, the data returned. It isn't in a string format and String() isn't working on it.

• Cast/initialize submodels of a Backbone Model

  - by nambrot

  I think I have a pretty simple problem that is just pretty difficult to word and therefore hard to find a solution for. Setup: PathCollection is a Backbone.Collection of Paths Path is a Backbone.Model which contains NodeCollection (which is a Backbone.Collection) and EdgeCollection (which is a Backbone.Collection). When I fetch PathCollection paths = new PathCollection() paths.fetch() obviously, Paths get instantiated. However, I'm missing the spot where I can allow a Path to instantiate its submodels from the attribute hashes. I can't really use parse, right? Basically im looking for the entry point for a model when its instantiated and set with attributes. I feel like there must be some convention for it.

• How to Key-Value-Observe the rotation of a CALayer?

  - by HelloMoon

  I can access the value like this: NSNumber* rotationZ = [myLayer valueForKeyPath:@"transform.rotation.z"]; But for some reason, if I try to KV-observe that key path, I get a compiler error. First, this is how I try to do it: [myLayer addObserver:self forKeyPath:@"transform.rotation.z" options:0 context:nil]; The compiler tells me: *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ addObserver: forKeyPath:@"rotation.z" options:0x0 context:0x528890] was sent to an object that is not KVC-compliant for the "rotation" property.' what I don't get is, why I can access that z value by KVC key path, but not add an observer to it. Does this make sense? How else could I observe the z value of that matrix? I don't care about the other values of the matrix. Only the z rotation. Any other way to access and observe it?

• Assembly.CodeBase: when is it no file-URI?

  - by Marc Wittke

  Assembly.Location gives a plain path to the assembly. Unfortunately this is empty when running in a shadowed environment, such as unit test or ASP.NET. Hovever, the Codebase property is available and provides a URI that can be used instead. In which cases it returns no URI starting with file:///? Or in other words: what are the cases in which this won't work or will return unusable results? Assembly assembly = GetType().Assembly; Uri codeBaseUri = new Uri(assembly.CodeBase); string path = codeBaseUri.LocalPath;

• Why addming permissions to an existing AppDomain has no effect?

  - by MainMa

  Hi, I have a following code which behaves strangely in .NET 4.0: // AppDomain is created, and permissions which were added to `sandboxPermissions` are added successfully. sandboxAppDomain = AppDomain.CreateDomain("SandboxDomain", null, appDomainSetup, sandboxPermissions, new[] { commonStrongName }); // Trying to add a new permission to an AppDomain which is already created. sandboxAppDomain.PermissionSet.AddPermission(new FileIOPermission(FileIOPermissionAccess.AllAccess, @"C:\Some\Path\Here")); // Setting breakpoint to this line: `permissions` contains every permission which was added to `sandboxPermissions`, but no trace of C:\Some\Path\Here related permission. var permissions = sandboxAppDomain.PermissionSet.ToXml(); Every permission added before creating an AppDomain is just here, as expected. But adding permissions after an AppDomain is created has no effect at all. There are no exceptions thrown (nor first-chance ones). What can it be? If the framework method (AddPermission) fails to do what it was expected to do, mustn't it throw an exception?

• Avoiding dispose of underlying stream

  - by danbystrom

  I'm attempting to mock some file operations. In the "real" object I have: StreamWriter createFile( string name ) { return new StreamWriter( Path.Combine( _outFolder, name ), false, Encoding.UTF8 ) ); } In the mock object I'd like to have: StreamWriter createFile( string name ) { var ms = new MemoryStream(); _files.Add( Path.Combine( _outFolder, name ), ms ); return new StreamWriter( ms, Encoding.UTF8 ) ); } where _files is a dictionary to store created files for later inspection. However, when the consumer closes the StreamWriter, it also disposes the MeamoryStream... :-( Any thoughts on how to pursue this?

• Java regex replace multiple file paths in a large String

  - by Joe Goble

  So a Regex pro I am not, and I'm looking for a good way to do this. I have a large string which contains a variable number <img> tags. I need to change the path on all of these images to images/. The large string also contains other stuff not just these img's. <img src='http://server.com/stuff1/img1.jpg' /> <img src='http://server.com/stuff2/img2.png' /> Replacing the server name with a ReplaceAll() I could do, it's the variable path in the middle I'm clueless on how to include. It doesn't necessarily need to be a regex, but looping through the entire string just seems wasteful.

• Rmagick Fails To Manipulate PNG

  - by Tyler DeWitt

  Following the Railscast episode on CarrierWave: I installed ImageMagick on Mountain Lion via homebrew, exported the following path: export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH" Symlinked the following: ln -s /usr/local/include/ImageMagick/wand /usr/local/include/wand ln -s /usr/local/include/ImageMagick/magick /usr/local/include/magick And installed rmagick via bundler. In my uploader I have the following: include CarrierWave::RMagick version :thumb do process :resize_to_limit => [85, 85] end Which creates thumbnails just fine, but not for png files. I've tried a handful of png images and it always fails with this error: Failed to manipulate with rmagick, maybe it is not an image? Original Error: no decode delegate for this image format `<path>/public/uploads/tmp/20121022-2133-9885-3333/thumb_cat_vs_internet.png' @ error/constitute.c/ReadImage/544 jpeg images work just fine. EDIT identify -list format | grep -i png returns nothing, indicating the png decode delegate is probably missing. Now what?

• Vibrations when exploding/repacking movie

  - by Stefano Borini

  Please bear with me, I know that what I'm doing can sound strange, but I can guarantee there's a very good reason for that. I took a movie with my camera, as avi. I imported the movie into iMovie and then exploded the single frames as PNG. Then I repacked these frames into mov using the following code movie, error = QTMovie.alloc().initToWritableFile_error_(out_path, None) mt = QTMakeTime(v, scale) attrib = {QTAddImageCodecType: "jpeg"} for path in png_paths: image = NSImage.alloc().initWithContentsOfFile_(path) movie.addImage_forDuration_withAttributes_(image, mt, attrib) movie.updateMovieFile() The resulting mov works, but it looks like the frames are "nervous" and shaky when compared to the original avi, which appears smoother. The size of the two files is approximately the same, and both the export and repacking occurred at 30 fps. The pics also appear to be aligned, so it's not due to accidental shift of the frames. My question is: by knowing the file formats and the process I performed, what is the probable cause of such result ? How can I fix it ?

• Make xargs execute the command once for each line of input

  - by Readonly

  How can I make xargs execute the command exactly once for each line of input given? It's default behavior is to chunk the lines and execute the command once, passing multiple lines to each instance. From http://en.wikipedia.org/wiki/Xargs: find /path -type f -print0 | xargs -0 rm In this example, find feeds the input of xargs with a long list of file names. xargs then splits this list into sublists and calls rm once for every sublist. This is more efficient than this functionally equivalent version: find /path -type f -exec rm '{}' \; I know that find has the "exec" flag. I am just quoting an illustrative example from another resource.
