  • Monotouch Example for QuickLook PDF

    - by nbonwit
    I am looking for a bare-bones pdf viewer example using the QuickLook Monotouch API. I have searched and have found bits and pieces but just can't seem to get it all integrated. I will be reading the pdf from a file pre-saved to the Personal folder on the iPad and would like to show the pdf as a modal view. If someone could post a bare-bones example, that would be much appreciated. What I have so far is below. Thanks! path = Environment.GetFolderPath(Environment.SpecialFolder.Personal); pdfPath = System.IO.Path.Combine(path, "pdfReport.pdf"); QLPreviewController myPdfController = new QLPreviewController(); MyPdf pdfToShow = new MyPdf("", new Uri("")); // Not sure about this line myPdfController.DataSource = pdfPath; // Not sure what this line should be PresentModalViewController(myPdfController, true);

  • HTML Upload Form will only upload files found in the directory of the PHP file.

    - by vette982
    I have an image uploader that uses the imgur.com API and jQuery's .ajax() function to upload images to their servers. However, if I browse for an image using the <input type="file"/> element of the form, it will only be successful in uploading an image if the image file is found in the same directory as the page.php file that the form is found in (shown below). How can I allow the form to upload images from any directory on my computer? page.php: <form action="page.php" method="post"> <input type="file" name="doc" id="doc" /><br/> <input type="image" src="go.gif" name="submit" id="submit" /> </form>

  • Facebook Is it possible to grab a user's data and populate a form in an iframe?

    - by super9
    I am trying to create an iframe tab for a Facebook Page. On this page, I am loading in an iframe which consists of a form from another domain/site. Is it possible to use javascript to query the graph api to load the user's data into this iframe loaded form using javascript such that is appears pre-populated to the user? I am aware that there is a cross domain security issue. In that case, suppose that my iframe tab is now hosted on the same domain as the iframe loaded form, will this be doable now?

  • Patterns for simulating optional "out" parameters in C#?

    - by Jesse McGrew
    I'm translating an API from C to C#, and one of the functions allocates a number of related objects, some of which are optional. The C version accepts several pointer parameters which are used to return integer handles to the objects, and the caller can pass NULL for some of the pointers to avoid allocating those objects: void initialize(int *mainObjPtr, int *subObjPtr, int *anotherSubObjPtr); initialize(&mainObj, &subObj, NULL); For the C# version, the obvious translation would use out parameters instead of pointers: public static void Initialize(out int mainObj, out int subObj, out int anotherSubObj); ... but this leaves no way to indicate which objects are unwanted. Are there any well-known examples of C# APIs doing something similar that I could imitate? If not, any suggestions?

  • Windows secure pinned website tile

    - by Stijn de Voogd
    I'm currently working on a pinned website tile for my website and instead of using a static XML file i'm linking the tile to a web api that returns user specific XML. My question is: Is it possible to secure this tile so that a user needs to be logged in before the data loads? The pinned website livetile doesn't send any security request headers/ cookies: - Http: Request, GET /v1/livetile/firsttile Command: GET + URI: /v1/livetile/firsttile ProtocolVersion: HTTP/1.1 UserAgent: Microsoft-WNS/6.3 Host: 192.168.14.109:2089 Cache-Control: no-cache HeaderEnd: CRLF Sidenote: Notice how it's not even sending an accept header even though it only wants xml.

  • Retrieve binary data from S3 storage through AWS.NET in C#

    - by BerggreenDK
    I've tested most of the included samples in the AWS SDK for .NET and they all works fine. I can PUT objects, LIST objects and DELETE objects in a bucket, but... lets say I delete the original and want to sync those files missing locally? I would like to make a GET object (by key/name and bucket ofcause). I can find the object, but how do I read the binary data from S3 through the API? Do I have to write my own SOAP wrapper for this or is there some kinda sample for this out "here" ? :o) In hope of a sample. It does not have to tollerate execeptions etc. I just need to see the main parts that connects, retreives and stores the file back on my ASP.net or C# project. Anyone???

  • How do I blur (ios7 style) a section of an image in a UITableViewCell?

    - by George McKibbin
    I've got a UIImageView that takes up the whole cell and shows an image. I'd like to blur the bottom third of the view in the iOS7 style (we're targeting iOS7). There will be a label over the blurred part. The issue seems to be that I can't "screenshot" the UIImageView right as I am setting up the cell in tableView:cellForRowAtIndexPath: as it hasn't loaded yet. Although i've even tried setting up a timer for a 0.1 second delay and that also doesn't work. I've tried the stuff on http://damir.me/posts/ios7-blurring-techniques I've tried https://github.com/justinmfischer/7blur I'd like to use the new screenshotting API drawViewHierarchyInRect:afterScreenUpdates: I'd also like to use apple's sample code UIImage+ImageEffects The only thing that has worked so far has been to just put a UIToolbar in but the performance is really slow. I don't need dynamic updates. I've managed to get the following effect a few times but it has just tinted the view and hasn't actually blurred anything so I'm a bit confused.

  • Are there any free .NET OCR libraries that will perform OCR on an application window directly?

    - by Kelsey
    I am looking for a free .NET OCR library that will be able to do OCR on a given application window or even a image in memory (I can take a snapshot of the application window myself). I have looked at tessnet2 and MODI but both require an image located on disk. I need to use OCR because the application I am trying to write a script for does some wacky stuff that cannot be read using windows API and I need to scrape data from the screen. I have tested both of tessnet2 and MODI and they both can read the text mostly but because this has to run in an enviroment that will not be able to write to disk, I need it to be able to read directly from the applciation window or some type of memory stream. I am thinking OCR is my only soution but there could be other methods that I am not thinking of. Suggestions?

  • Interface Design Problem: Storing Result of Transactions

    - by jboyd
    Requirements: multiple sources of input (social media content) into a system multiple destinations of output (social media api's) sources and destinations WILL be added some pseudo: IContentProvider contentProvider = context.getBean("contentProvider"); List<Content> toPost = contentProvider.getContent(); for (Content c : toPost) { SocialMediaPresence smPresence = socialMediaService.getSMPresenceBySomeId(c.getDestId()); smPresence.hasTwitter(); smPresence.hasFacebook(); //just to show what this is smPresence.postContent(c); //post content could fail for some SM platforms, but shoulnd't be lost forever } So now I run out of steam, I need to know what content has been successfully posted, and if it hasn't gone too all platforms, or if another platform were added in the future that content needs to go out for it as well (therefore my content provider will need to not only know if content has gone out, but for what platforms). I'm not looking for code, although sample/pseudo is fine... I'm looking for an approach to this problem that I can implement

  • Efficient way to calculate byte length of a character, depending on the encoding

    - by BalusC
    What's the most efficient way to calculate the byte length of a character, taking the character encoding into account? In UTF-8 for example the characters have a variable byte length, so each character needs to be determined individually. As far now I've come up with this: char c = getItSomehow(); String encoding = "UTF-8"; int length = new String(new char[] { c }).getBytes(encoding).length; But this is clumsy and inefficient in a loop since a new String needs to be created everytime. I can't find other and more efficient ways in the Java API. I imagine that this can be done with bitwise operations like bit shifting, but that's my weak point and I'm unsure how to take the encoding into account here :) If you question the need for this, check this topic.

  • Using sphinx to create context sensitive html help

    - by bluebill
    Hi all, I am currently using AsciiDoc (http://www.methods.co.nz/asciidoc/) for documenting my software projects because it supports pdf and html help generation. I am currently running it through cygwin so that the a2x tool chain functions properly. This works well for me but is a pain to setup on other windows computers. I have been looking for alternative methods and recently revisited Sphinx. Noticing that it now produces html help files I gave it a try and it seems to work well in the small tests I performed. My question is, is there a way to specify map id's for context sensitive help in the text so that my windows programs can call the proper help api and the file is launched and opened to the desired location? In AsciiDoc I am using "pass::[]". By using these constructs a context.h and alias.h are generated along with the other html help files (context sensitive help information).

  • What is the correct way to specify dimensions in DIP from Java code ?

    - by Pavel Lahoda
    Trying to digest docs about design Multiple resolutions (http://d.android.com/guide/practices/screens_support.html#dips-pels) I found that it is possible to set dimensions of my interface elements in XML layouts using DIPs as in following fragment : "android:layout_width="10dip" But all Java interface takes integer as arguments and there is no way to specify dimensions in DIPs. What is the correct way to calculate this ? I figured that I have to use property density of DisplayMetrics class but is this a correct way ? May I relly that formula : pixels * DisplayMetrics.density = dip is always correct ? Will there be API in DIPs for Java ?

  • Real-time data on webpage with jQuery

    - by Steven Hepting
    I would like a webpage that constantly updates a graph with new data as it arrives. Regularly, all the data you have is passed to the page at the beginning of the request. However, I need the page to be able to update itself with fresh information every few seconds to redraw the graph. Background The webpage will be similar to this http://www.panic.com/blog/2010/03/the-panic-status-board/. The data coming in will temperature values to be graphed measured by an Arduino and saved to the Django database (this part is already complete). Update It sounds as though the solution is to use the jQuery.ajax() function ( http://api.jquery.com/jQuery.ajax/) with a function as the .complete callback that will schedule another request several seconds later to a URL that will return the data in JSON format. How can that method be scheduled? With the .delay() function?

  • Classloader problems Tomcat 6 javagent

    - by alecswan
    I am using Salve Dependency Injection library that instruments the byte code of the web application. I specified -javaagent in Tomcat VM options and pointed it to the Salve agent jar. The agent jar gets loaded, but then it throws a java.lang.NoClassDefFoundError unable to find classes that are in other Salve jars which are located in WEB-INF/lib folder of my web app. I can solve this problem by putting those JARs in Tomcat/endorsed folder. However, some of those jars depend on third-party libraries, such as Spring and servlet-api.jar. Therefore, I am forced to put all these dependencies in Tomcat/endorsed as well. Could anybody suggest a better way for handling dependencies of a Tomcat javaagent? Thanks.

  • Example code of libssh2 being used for port forwarding

    - by flxkid
    I'm looking for an example of how to use libssh2 to setup ssh port forwarding. I've looked at the API, but there is very little in the way of documentation in the area of port forwarding. For instance, using PuTTY plink, There is the remote port to listen on, but also the local port that traffic should be sent to. Is it the developers responsibility to do this part? Can an example be developed of this? Also, for the opposite, where a remote port is brought to a local port, do I use libssh2_channel_direct_tcpip_ex? What about an example of this? I really need to do this exact thing on a project right now. How hard would it be to develop a couple of samples of this? I'm willing to put up a bounty if need be to get a couple of working examples of this.

  • ec2_bundle_vol fails with error LoadError

  • Windows disassembler: looking for a tool...

    - by SigTerm
    Hello. I'm looking for a (preferably free) tool that can produce "proper" disassembly listing from a (non-.NET) windows PE file (*.exe or *.dll). Important requirement: it should be possible to run the listing through a windows assembler (nasm, masm or whatever) and get working exe again (not necessarily identical to original one, but it should behave in the same way). Intended usage is adding new subroutines into existing code, when source is not available. Ideally, tool should be able to detect function/segment boundaries, API calls, and generate proper labels for jumps (I can live without labels for loops/jumps, though, but function boundary detection would be nice), and keep program resources/segments in place. I'm already aware of IdaPRO(not free), OllyDBG (useful for in-place hacking, doesn't generate disassembly listing, AFAIK), ndisasm (output isn't suitable for assembler), dumpbin (useful, but AFAIK, output isn't suitable for assembler) and "proxy dll" technique. Ideas? Or maybe there is a book/tutorial that explains some kind of alternative approach?

  • Not-quite-JSON string deserialization in Python

    - by cpharmston
    I get the following text as a string from an XML-based REST API 'd':4 'ca':5 'sen':1 'diann':2,6,8 'feinstein':3,7,9 that I'm looking to deserialize into a pretty little Python dictionary: { 'd': [4], 'ca': [5], 'sen': [1], 'diann': [2, 6, 8], 'feinstein': [3, 7, 9] } I'm hoping to avoid using regular expressions or heavy string manipulation, as this format isn't documented and may change. The best I've been able to come up with: members = {} for m in elem.text.split(' '): m = m.split(':') members[m[0].replace("'", '')] = map(int, m[1].split(',')) return members Obviously a terrible approach, but it works, and that's better than anything else I've got right now. Any suggestions on better approaches?

  • Code Profiling in the Windows Sidebar Environment

    - by Matt
    Does anyone know of a way I can code-profile my Windows Sidebar Gadget? I've played around with the code-profiling tool in IE8's "Developer Tools" and the code-profiling included in Visual Studio 2010, but I can't find a way to include the System.* API, which my gadget relies on (as it is standard in the Sidebar environment). The gadget also relies on cross-domain AJAX requests; which is normally permitted in the Sidebar environment. By code-profiling I primarily mean: Function call count Function execution time Any ideas would be much appreciated. Regards, Matt

  • Why is the class wrong for NSFetchRequest?

    - by Stephen Furlani
    Hello, I am working with an undocumented API (Osirix) and I have a sister-question to the one I posted here. I am having trouble loading objects from a managed object context. With loading from API, using their instance of _context and _model 2010-05-28 14:05:13.588 OsiriX[44012:a0f] Entity: Study 2010-05-28 14:05:13.589 OsiriX[44012:a0f] EntityClassName: DicomStudy 2010-05-28 14:05:13.589 OsiriX[44012:a0f] ClassName: DicomStudy With loading from Fetch Request (and my own instance of _context, and _model) 2010-05-28 14:19:09.956 rcOsirix[44431:7a03] Entity: Study 2010-05-28 14:19:09.957 rcOsirix[44431:7a03] EntityClassName: DicomStudy 2010-05-28 14:19:09.958 rcOsirix[44431:7a03] ClassName: NSManagedObject output given by: NSLog(@"Entity: %@",[[item entity] name]); NSLog(@"EntityClassName: %@", [[item entity] managedObjectClassName]); NSLog(@"ClassName: %s", class_getName(object_getClass([item class]))); So it is obvious that even though the Entity thinks it is a DicomSeries - it is not. It is just a NSManagedObject. DicomSeries has some "hard-coded" KVC stuff that I ran into a problem with in my other question. I'm pursuing a different line of reasoning in this thread - with the loading of the objects. The following is their code: - (NSManagedObjectModel *)managedObjectModel { if (managedObjectModel) return managedObjectModel; NSMutableSet *allBundles = [[NSMutableSet alloc] init]; [allBundles addObject: [NSBundle mainBundle]]; [allBundles addObjectsFromArray: [NSBundle allFrameworks]]; managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL: [NSURL fileURLWithPath: [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"/OsiriXDB_DataModel.mom"]]]; [allBundles release]; return managedObjectModel; } - (NSManagedObjectContext *) managedObjectContextLoadIfNecessary:(BOOL) loadIfNecessary { NSError *error = nil; NSString *localizedDescription; NSFileManager *fileManager; if( currentDatabasePath == nil) return nil; if (managedObjectContext) return managedObjectContext; if( loadIfNecessary == NO) return nil; fileManager = [NSFileManager defaultManager]; [persistentStoreCoordinator release]; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: self.managedObjectModel]; managedObjectContext = [[NSManagedObjectContext alloc] init]; [managedObjectContext setPersistentStoreCoordinator: persistentStoreCoordinator]; NSURL *url = [NSURL fileURLWithPath: currentDatabasePath]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:url options:nil error:&error]) { NSLog(@"********** managedObjectContextLoadIfNecessary FAILED: %@", error); localizedDescription = [error localizedDescription]; error = [NSError errorWithDomain:@"OsiriXDomain" code:0 userInfo:[NSDictionary dictionaryWithObjectsAndKeys:error, NSUnderlyingErrorKey, [NSString stringWithFormat:@"Store Configuration Failure: %@", ((localizedDescription != nil) ? localizedDescription : @"Unknown Error")], NSLocalizedDescriptionKey, nil]]; } [[managedObjectContext undoManager] setLevelsOfUndo: 1]; [[managedObjectContext undoManager] disableUndoRegistration]; // This line is very important, if there is NO database.sql file [self saveDatabase: currentDatabasePath]; return managedObjectContext; } This is my code: NSManagedObjectModel* DataModule::managedObjectModel() { if (_managedObjectModel) return _managedObjectModel; NSMutableSet *allBundles = [[NSMutableSet alloc] init]; [allBundles addObject: [NSBundle mainBundle]]; [allBundles addObjectsFromArray: [NSBundle allFrameworks]]; _managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL: [NSURL fileURLWithPath: [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"/OsiriXDB_DataModel.mom"]]]; [allBundles release]; return [_managedObjectModel retain]; } ... NSError *error = nil; [_storeCoordinator release]; _storeCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: managedObjectModel()]; _context = [[NSManagedObjectContext alloc] init]; [_context setPersistentStoreCoordinator: _storeCoordinator]; NSURL *url = [NSURL fileURLWithPath: [[NSString alloc] initWithCString:_DBPath.c_str()]]; if (url == nil) { [pool release]; _loadLock = false; return nil; } if (![_storeCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:url options:nil error:&error]) { NSLog(@"********** managedObjectContextLoadIfNecessary FAILED: %@", error); NSString *localizedDescription = [error localizedDescription]; error = [NSError errorWithDomain:@"OsiriXDomain" code:0 userInfo:[NSDictionary dictionaryWithObjectsAndKeys:error, NSUnderlyingErrorKey, [NSString stringWithFormat:@"Store Configuration Failure: %@", ((localizedDescription != nil) ? localizedDescription : @"Unknown Error")], NSLocalizedDescriptionKey, nil]]; //Exit Failure [pool release]; _loadLock = false; return nil; } [[_context undoManager] setLevelsOfUndo: 1]; [[_context undoManager] disableUndoRegistration]; ... I am including all the same frameworks.... but _allBundles isn't even used to create the managedObjectModel so I don't know what it's supposed to do except load them into memory so that the mom can look at them while loading. Totally lost. Help! Why would objects returned by my FetchRequest with the same Entity come out as NSManagedObjects and not DicomStudys? I'm including DicomStudy.h so it should see the object during creation of the model, context, and fetch request. [request setEntity: [[managedObjectModel() entitiesByName] objectForKey:@"Study"]]; Thanks in advance, -Stephen

  • FIPS-compliant encryption in .NET 2.0

    - by Odrade
    We have a .NET 2.0 application that uses the RijindaelManaged class to encrypt some sensitive data. This was fine until we ran into some machines that require the use of FIPS-compliant algorithms. We'd like to switch to AesCryptoServiceProvider, but most of our target machines haven't upgraded past .NET 2.0. Requiring an upgrade is out of the question. After all, upgrades are scary! Is there any way we could use AesCryptoServiceProvider in a .NET 2.0 application? Since 3.5 uses the 2.0 CLR, I was hoping there might be a way to build the needed libraries into the app. Failing that, could someone point me to a reference on the native API that's wrapped by AesCryptoServiceProvider?
