  • Const unsigned char* to char*

    - by BSchlinker
    So, I have two types at the moment: const unsigned char* unencrypted_data_char; string unencrypted_data; I'm attempting to perform a simple conversion of data from one to the other (string - const unsigned char*) As a result, I have the following: strcpy((unencrypted_data_char),(unencrypted_data.c_str())); However, I'm receiving the error: error C2664: 'strcpy' : cannot convert parameter 1 from 'const unsigned char *' to 'char *' Any advise? I thought using reinterpret_cast would help, but it doesn't seem to make a difference.

  • Android: getTag/setTag and IllegalArgumentException

    - by Sparafusile
    Yes, I know you need a unique resource id when calling the version of these functions that requires a key, but I cannot for the life of me figure out how to create a resource id that can be used in this way. A final variable in my class wont work and neither will a hard coded value. Both threw an IllegalArgumentException. So what gives, how do you use these methods? Spara

  • Python requests - saving cookie for later url usage

    - by PythonRocks
    I been trying to get a cookie and post it to a url in later use in the program, but I cant seem to get the cookie parameters to work. Right now I have response = requests.get("url") But how exactly do I retrive cookies from this url and post them to a new url (the same cookies). The tutorial in requests is somewhat vague on the topic and gives examples I cannot test. Hope someone can help with further examples. This is python 2.7 btw.

  • Possible to open a text file in a MYSQL stored procedure?

    - by futureelite7
    Is it possible to open and read from a text file in a MYSQL stored procedure? I have a text file with a list of about 50k telephone numbers, and want to write a stored procedure that will open the file, read the 50k lines and store it as rows in a table. I cannot load the file directly using LOAD IN FILE as the table has additional columns that I have to set. Thanks!

  • django-multilingual and switching between languages on template side

    - by israkir
    I am trying to use django-multilingual and setup it properly. But what I found is that everything is clear for django-multilingual except a template usage example. I just started to use django and I don't know, maybe because of this reason, I cannot figure out how to switch between languages on template side. Is there any example that you can give or any 'more' clear source/documentation about this?

  • running a python script where dependencies are not avail: distributed computing

    - by sadhu_
    Hi, I have access to a grid (running condor) that would (potentially) allow to very substantially reduce how long by nltk based nlp tasks take. unfortunately, i dont have root access on the cluster so cannot install new packages, only run whatever is available on the linux boxes. python is of course available, but nltk isnt - i was wondering however, if there might be a way around this somehow ? is there a way i can somehow still distribute the task in a self-contained 'package' of some sort? Thanks for your hel

  • Implement looped movement animation with tap to cancel

    - by Nader
    Hi All; My app is based around a grid and an image that moves within a grid that is contained within a scrollview. I have an imageview that I am animating from one cell to another in time with a slow finger movement and recentering the scrollview. That is rather straight forward. I have also implement the ability to detect a swipe and therefore move the image all the way to the end of the grid and the uiscrollview recentering. I have even implemented the ability to detect a subsequent tap and freeze the swiped movement. The issue with the swipe movement is that the UIScrollView will scroll all the way to the end before the Image reaches the end and so I have to wait for the image to arrive. Also, when I freeze the movement of the image, I have to re-align the image to a cell (which I can do). I have come to the realization that I have to animate the image one cell at a time for swipes and recentering the uiscrollview before moving the image to the next cell. I have attempted to implement this but I cannot come up with a solution that works or works properly. Can anyone suggest how I go about implementing this? Even if you are able to put up code from a different example or sudo code, it would help a lot as I cannot workout how this should be done, should I be using selectors, a listener in delegates, I just simply lack the experience to solve this design pattern. Here is some code: Note that the sprite is an UIImageView - (void)animateViewToPosition:(SpriteView *)sprite Position:(CGPoint)pos Duration:(CFTimeInterval)duration{ CGMutablePathRef traversePath = CGPathCreateMutable(); CGPathMoveToPoint(traversePath, NULL, sprite.center.x, sprite.center.y); CGPathAddLineToPoint(traversePath, NULL, pos.x, pos.y); CAKeyframeAnimation *traverseAnimation = [CAKeyframeAnimation animationWithKeyPath:kAnimatePosition]; traverseAnimation.duration = duration; traverseAnimation.removedOnCompletion = YES; traverseAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]; traverseAnimation.delegate = sprite; traverseAnimation.path = traversePath; CGPathRelease(traversePath); [sprite.layer addAnimation:traverseAnimation forKey:kAnimatePosition]; sprite.center = pos; }

  • Passing a ManagedObjectContext to a second view

    - by amo
    I'm writing my first iPhone/Cocoa app. It has two table views inside a navigation view. When you touch a row in the first table view, you are taken to the second table view. I would like the second view to display records from the CoreData entities related to the row you touched in the first view. I have the CoreData data showing up fine in the first table view. You can touch a row and go to the second table view. I'm able to pass info from the selected object from the first to the second view. But I cannot get the second view to do its own CoreData fetching. For the life of me I cannot get the managedObjectContext object to pass to the second view controller. I don't want to do the lookups in the first view and pass a dictionary because I want to be able to use a search field to refine results in the second view, as well as insert new entries to the CoreData data from there. Here's the function that transitions from the first to the second view. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here -- for example, create and push another view controller. NSManagedObject *selectedObject = [[self fetchedResultsController] objectAtIndexPath:indexPath]; SecondViewController *secondViewController = [[SecondViewController alloc] initWithNibName:@"SecondView" bundle:nil]; secondViewController.tName = [[selectedObject valueForKey:@"name"] description]; secondViewController.managedObjectContext = [self managedObjectContext]; [self.navigationController pushViewController:secondViewController animated:YES]; [secondViewController release]; } And this is the function inside SecondViewController that crashes: - (void)viewDidLoad { [super viewDidLoad]; self.title = tName; NSError *error; if (![[self fetchedResultsController] performFetch:&error]) { // <-- crashes here // Handle the error... } } - (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController != nil) { return fetchedResultsController; } /* Set up the fetched results controller. */ // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; // Edit the entity name as appropriate. // **** crashes on the next line because managedObjectContext == 0x0 NSEntityDescription *entity = [NSEntityDescription entityForName:@"SecondEntity" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // <snip> ... more code here from Apple template, never gets executed because of the crashing return fetchedResultsController; } Any ideas on what I am doing wrong here? managedObjectContext is a retained property. UPDATE: I inserted a NSLog([[managedObjectContext registeredObjects] description]); in viewDidLoad and it appears managedObjectContext is being passed just fine. Still crashing, though. Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '+entityForName: could not locate an NSManagedObjectModel for entity name 'SecondEntity''

  • How to read unix usage

    - by sixtyfootersdude
    I did some searching but I cannot find documentation on how unix usage works. I know somethings (mostly through trial and error) but for example how do I know that: /usr/bin/ls [-aAbcCdeEfFghHilLmnopqrRstuvVx1@] [file]... Means that you can include more than one option. Ie: ls -la Can someone point me to some documentation on what the usage syntax is.

  • Where is the node.js file in the stack trace located?

    - by user225189
    Obviously, I'm pretty new to node.js. I'm attempting to debug a node.js application and I see node.js in the stack trace. I would like to put some sys.puts calls in there, but I cannot locate the node.js that is being run by my server. Is there a way to tell where node.js is located? Is there an equivalent to Ruby's FILE in node? Thanks, Brian

  • Custom model in ASP.NET MVC controller: Custom display message for Date DataType

    - by Rita
    Hi I have an ASP.NET MVC Page that i have to display the fields in customized Text. For that I have built a CustomModel RequestViewModel with the following fields. Description, Event, UsageDate Corresponding to these my custom Model has the below code. So that, the DisplayName is displayed on the ASP.NET MVC View page. Now being the Description and Event string Datatype, both these fields are displaying Custom DisplayMessage. But I have problem with Date Datatype. Instead of "Date of Use of Slides", it is still displaying UsageDate from the actualModel. Anybody faced this issue with DateDatatype? Appreciate your responses. Custom Model: [Required(ErrorMessage="Please provide a description")] [DisplayName("Detail Description")] [StringLength(250, ErrorMessage = "Description cannot exceed 250 chars")] // also need min length 30 public string Description { get; set; } [Required(ErrorMessage="Please specify the name or location")] [DisplayName("Name/Location of the Event")] [StringLength(250, ErrorMessage = "Name/Location cannot exceed 250 chars")] public string Event { get; set; } [Required(ErrorMessage="Please specify a date", ErrorMessageResourceType = typeof(DateTime))] [DisplayName("Date of Use of Slides")] [DataType(DataType.Date)] public string UsageDate { get; set; } ViewCode: <p> <%= Html.LabelFor(model => model.Description) %> <%= Html.TextBoxFor(model => model.Description) %> <%= Html.ValidationMessageFor(model => model.Description) %> </p> <p> <%= Html.LabelFor(model => model.Event) %> <%= Html.TextBoxFor(model => model.Event) %> <%= Html.ValidationMessageFor(model => model.Event) %> </p> <p> <%= Html.LabelFor(model => model.UsageDate) %> <%= Html.TextBoxFor(model => model.UsageDate) %> <%= Html.ValidationMessageFor(model => model.UsageDate) %> </p>

  • HTML::Mason file upload

    - by marghi
    Recently I've been trying to get some files uploaded on to my server in my HTML::Mason application. All good no problems there apparently Mason a filehandle directly in the argument. The problem is that I cannot retrieve the filename from that filehandle in a elegant way. One method of resolving this issue is parsing the filename on the client before sending it to the server and placing the extracted value in a hidden field so that it gets sent upon submit. BUT that is very unsafe!

  • Possible to repair garbled Chinese filenames?

    - by futureelite7
    I'm downloading via FTP some files with chinese names (BIG5 encoded), and Filezilla displays those filenames as garbage (as FTP cannot handle any encoding other than ASCII and UTF-8, as least the standard compliant ones). Given a filename with garbled characters, is it possible for me to repair the encoding and get a proper filename String given that I already know the source encoding? Will the FTP client misinterpreting BIG5 as UTF-8 insert bytes that make conversion back to BIG5 difficult?

  • Any porting available of backtrace for uclibc?

    - by user303967
    We are running the uclibc linux on ARM 9. The problem is uclibc doesn't support backtrace. When a core dump happens, I cannot grab the call stack. Does anyone have a good solution for that? For example, an existing porting of backtrace for uclibc, or any good method to grab the call stack when a core dump happens (uclibc+ARM+Linux)?
