  • Best way to parse XMPP-like XML streams?

    - by codethief
    I am working on a server application which receives data over a TCP socket in an XMPP-like XML format, i.e. every child of the <root> element essentially represents one separate request (stanza). The connection is closed as soon as </root> is received. I do know that I must use a stream parser like SAX, somehow. Though, for convenience, I'd prefer to have a tree-like interface to access each stanza's child elements. (The data sent with every request is not large so I think it makes sense to read each stanza as a whole.) What's the best way to realize that in Python (preferably v3)? This is the code I'd like to build it in. Feel free to point me in a totally different direction to solve this issue. import socketserver import settings class MyServer(socketserver.ThreadingMixIn, socketserver.TCPServer): pass class MyRequestHandler(socketserver.StreamRequestHandler): def handle(self): pass if __name__ == '__main__': server = MyServer((settings.host, settings.port), MyRequestHandler) server.serve_forever()

    - by Risma
    hi i have a textview and i want to get the selectedRange.location value from that textview. in the first time when the keyboard appear, the location value always show an integer point such as 110, or others. But if i dissappear the keyboard and then appear the keyboard again, the location value always show 2147483647. What is this 2147483647 mean and how to get the real location value? This is my code in the keyboard will appear method : -(void)keyboardWillAppear:(NSNotification *)notification { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:[[[notification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]]; CGRect keyboardEndingUncorrectedFrame = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey ] CGRectValue]; CGRect keyboardEndingFrame = [self.view convertRect:keyboardEndingUncorrectedFrame fromView:nil]; [UIView commitAnimations]; NSRange selectedRange = textview.selectedRange; NSLog(@"selected Range location : %f", selectedRange.location); }

  • Change Interval Of CADisplayLink

    - by user3679109
    I have replaced an NSTimer with a CADisplayLink. I have it working properly but it is running too slowly. How could I go about speeding this up? This is the code that I'm using: ViewController.h (In {} with @interface: CADisplayLink *displayLink; ViewController.m (viewDidLoad): displayLink = [CADisplayLink displayLinkWithTarget:self selector:@selector(onTimer)]; [displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes]; onTimer is the method that it is calling. So my question is how do I speed up how often this is being called? Thanks

  • TabBars and iOS 7

    - by MichaelScaria
    I have a UITabbarController that I'm pushing another controller on top of using a UINavigationController. On iOS 6 and below, the tabBar of the parent controller slides away and the toolbar of the new view controller is presented. But on iOS 7 the tabBar doesn't animate away even if I run the code [self.navigationController setToolbarHidden:YES animated:NO]; EDIT - Okay I narrowed my problem to iOS 7 not respecting the hidesBottomBarWhenPushed property, I followed the answers in hidesBottomBarWhenPushed ignored in iOS 7 but it didn't work. The view that is pushed has a toolbar with buttons and the buttons are responding to touches, it's just that the tabBar is on top of the toolbar.

  • MonoTouch- 'curated' bindings?

    - by Glinkot
    I'm just converting a video player sample to MT and came to this part: self.view.layer.sublayerTransform = CATransform3DMakePerspective(1000); In Monotouch, I've started with: this.View.Layer.SublayerTransform(CATransform3D.... But no perspective option is available. There is a 'scale' and 'rotate' one - does this mean this functionality is unavailable in MT? Or that I need to start creating my own bindings even though this one has been processed by the binding creation tool Xamarin uses? If anyone could advise how I would apply that transform I'd appreciate it. Cheers

  • iPhone: Switching Views From Outside Root Controller

    - by senfo
    I am using a UINavigationController to switch between views. What I would like is for each view to have the ability to control when it is swapped out for another view by having buttons within the view. All of the samples I've seen thus far have placed buttons on a toolbar, which is located on the root view containing the Switch View Controller rather than the views, them self. Is it possible to do what I want? I can't figure how to wire up the connection back to the UINavigationController. I'm having a difficult time wording this, so please feel free to let me know if you need additional clarification.

  • How can I make text in a UILabel non-centered?

    - by Sheehan Alam
    I have a UILabel: descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(200, 30, 130, 150)]; [descriptionLabel setFont:[Utils getSystemFontWithSize:14]]; [descriptionLabel setBackgroundColor:[UIColor clearColor]]; [descriptionLabel setTextColor:[UIColor whiteColor]]; descriptionLabel.numberOfLines = 0; descriptionLabel.lineBreakMode = UILineBreakModeWordWrap; [self addSubview:descriptionLabel]; If the text is only 1 line long it will appear in the middle of the label. Is there anyway I can have the text display from the top left corner of the label instead of the middle center?

    I'm trying to call a method of the below (Scroll animation class) type from a viewcontroller class. -(void)CreateLabel:(CGRect )frame andLabel:(UILabel *[NUM_LABELS])label andview:(UIView *)view; I got some errors when I tried passing the argument.

  • video streaming

    - by mawia
    Hi! all I am designing an application for streaming video.I have developed a model in which a server wait for incoming request.The server it self is serving to a good number of clients and it can't afford to serve any more clients.Now when the new connection comes,the server chooses from among it's clients a candidate client who will serve the request of the incoming client.Now the thing is that this choice should be very intelligent.Now I am using various heuristic like bandwidth of the selected client,it's location,distance from the requesting client to come at a decision.Now my question is,IS THERE AVAILABLE ANY TOOL TO FIND OUT BANDWIDTH,LOCATION of a host,and DISTANCE(my be in hop number)?for hop number I can use traceroute but that will be too expensive as it take long time sending reply from every intermediate router. Any help will be appreciated. Thanks!

  • SQL: joining multiples tables into one.

    - by Graveen
    I have 4 tables. r1, r2, r3 and r4. The table columns are the following: rId | rName I want to have, in fine, an unique table - let's call it R. Obviously, R will have the following structure: rTableName | rId | rName I'm looking for a solution, and the more natural for me is to: add a single column to all rX insert this column the table name i'm processing generate SQLs and concatenate them all Although I see exactly how to perform 1 and 3 with batching, editing, etc... (I have only to perform it once and for all), I don't see how to do the point 2: self-getting the tablename to insert into SQL. Have you an idea / or a different way to do that could solve my problem? Note: In fact, there are 250+ rX tables. That's why i can't do this manually. Note2: Precisely, this is with MySQL.

  • Urban Airship Tags issue

    - by Moshe
    I modified the alias sample code from: [request addRequestHeader: @"Content-Type" value: @"application/json"]; [request appendPostData:[[NSString stringWithFormat: @"{\"alias\": \"%@\"}", self.deviceAlias] dataUsingEncoding:NSUTF8StringEncoding]]; to: [request addRequestHeader: @"Content-Type" value: @"application/json"]; [request appendPostData:[[NSString stringWithFormat: @"{\"tags\": \"%@\"}", offsetStr] dataUsingEncoding:NSUTF8StringEncoding]]; offsetStr is a string containing a Timezone offset (which can be any number between -12 and 12). For some reason, Urban Airship is making each character of the string into its own tag. I've tried to substitute the - for a string neg with the same results. What's wrong?

  • ParentViewController returns nil

    - by Andreas Johannessen
    Hi I know there are many questions on this, but I don't get it to work. I present a UITabBarController with the presentModalViewController. However when I try to get title from the navigationItem title attribute in the UINavigationController class that presents the tabcontroller, it returns nil no matter what I do. I have the NSLog in the viewDidLoad method in tabcontroller class. I also cast the UIViewController which is returned by the self.parentViewController property. Then I try to access the title through: NSLog(@"%@", castedViewController.navigationItem.title); Any suggestions?

    - by luc
    Hello, I have the following table in the model with a recursive structure (a page can have children pages) class DynamicPage(models.Model): name = models.CharField("Titre",max_length=200) parent = models.ForeignKey('self',null=True,blank=True) I want to create another table with manytomany relation with this one: class UserMessage(models.Model): name = models.CharField("Nom", max_length=100) page = models.ManyToManyField(DynamicPage) The generated SQL creates the following constraint: ALTER TABLE `website_dynamicpage` ADD CONSTRAINT `parent_id_refs_id_29c58e1b` FOREIGN KEY (`parent_id`) REFERENCES `website_dynamicpage` (`id`); I would like to have the ManyToMany with the page itself (the id) and not with the parent field. How to modify the model to make the constraint using the id and not the parent? Thanks in advance

  • Creating a folder inside Mac OS App

    - by Negative Zero
    I want a an app that is "self-contained" (I don't know if i use the right word. "putting the app into trash bin will remove everything" is what I meant). But the app requires some resources to run. I usually put those resources into a folder. I want to move those resources into the App folder ( package contents). Can I do that? Is it a good practice to do that? When I test the app directly running from Xcode, the App runs fine. But if i run it from finder, the app will say fails to create resources folder because permission denied. I checked the app's folder permission - User(me) has read/write access. I am wondering what is causing this different behavior. The last option is to use Application Support folder, but I don't want to leave trails when user deletes the app. Can someone help me out here?

  • how to dynamically recolor a CGGradientRef

    I have three CGGradientRef's that I need to be able to dynamically recolor. When I Initialise the CGGradientRef's the first time I get the expected result, but every time I attempt to change the colors nothing happens. Why? gradient is an instance variable ins a subclass of CALayer: @interface GradientLayer : CALayer { CGGradientRef gradient; //other stuff } @end Code: if (gradient != NULL) { CGGradientRelease(gradient); gradient = NULL; } RGBA color[360]; //set up array CGColorSpaceRef rgb = CGColorSpaceCreateDeviceRGB(); gradient = CGGradientCreateWithColorComponents ( rgb, color, NULL, sizeof (color) / sizeof (color[0]) ); CGColorSpaceRelease(rgb); [self setNeedsDisplay];

  • Including full LaTeX documents within others.

    - by Chris Clarke
    I'm currently finishing off my dissertation, and would like to be able to include some documents within my LaTeX document. The files I'd like to include are weekly reports done in LaTeX to my supervisor. Obviously all documents are page numbered seperately. I would like them to be included in the final document. I could concatenate all the final PDFs using GhostScript or some other tool, but I would like to have consistent numbering throughout the document. I have tried including the LaTeX from each document in the main document, but the preamble etc causes problems and the small title I have in each report takes a whole page... In summary, I'm looking for a way of including a number of 1 or 2 page self-complete LaTeX files in a large report, keeping their original layouts, but changing the page numbering.
