  • Responding to preference updates in Android

    - by hgpc
    I am calling a PreferenceActivity from another activity and then updating the application state (ie: changing the font size) on onActivityResult, based on the preference changes. I was thinking it would be better to put the state update logic in the PreferenceActivity. That way I don't have the duplicate the logic in each activity that calls the PreferenceActivity. What's the best or correct way to do this?

  • PHP problem with getimagesize()

    - by RobHardgood
    I'm using the getimagesize() function in PHP and it keeps returning an error: getimagesize(image.php?name=username&pic=picture) [function.getimagesize]: failed to open stream: No such file or directory I'm not doing anything strange with it. The only problem I can imagine is that the path URL is another PHP script that returns a page with an image header, and there is an ampersand in that URL. Here is my code: $location = "image.php?name=username&pic=picture"; $size = getimagesize($location);

  • Damaged data when gzipping

    - by RadiantHeart
    This is the script I hva written for gzipping content on my site, which is located in 'gzip.php'. The way i use it is that on pages where I want to enable gzipping i include the file at the top and at the bottom i call the output function like this: print_gzipped_page('javascript') If the file is a css-file i use 'css' as the $type-argument and if its a php file i call the function without declaring any arguments. The script works fine in all browsers except Opera which gives an error saying it could not decode the page due to damaged data. Can anyone tell me what I have done wrong? <?php function print_gzipped_page($type = false) { if(headers_sent()){ $encoding = false; } elseif( strpos($_SERVER['HTTP_ACCEPT_ENCODING'], 'x-gzip') !== false ){ $encoding = 'x-gzip'; } elseif( strpos($_SERVER['HTTP_ACCEPT_ENCODING'],'gzip') !== false ){ $encoding = 'gzip'; } else{ $encoding = false; } if ($type!=false) { $type_header_array = array("css" => "Content-Type: text/css", "javascript" => "Content-Type: application/x-javascript"); $type_header = $type_header_array[$type]; } $contents = ob_get_contents(); ob_end_clean(); $etag = '"' . md5($contents) . '"'; $etag_header = 'Etag: ' . $etag; header($etag_header); if ($type!=false) { header($type_header); } if (isset($_SERVER['HTTP_IF_NONE_MATCH']) and $_SERVER['HTTP_IF_NONE_MATCH']==$etag) { header("HTTP/1.1 304 Not Modified"); exit(); } if($encoding){ header('Content-Encoding: '.$encoding); print("\x1f\x8b\x08\x00\x00\x00\x00\x00"); $size = strlen($contents); $contents = gzcompress($contents, 9); $contents = substr($contents, 0, $size); } echo $contents; exit(); } ob_start(); ob_implicit_flush(0); ?> Additional info: The script works if the length og the document beeing compressed is only 10-15 characters.

  • Reading server-side XML with JavaScript and jQuery

    - by Nick Lowman
    Hello, this is quite a simple question hopefully. Our client currently has a Flash banner ad on their site which they can change the text size, colour, position etc. by editing an XML file. They want to scrap flash and use JavaScript and jQuery. Now, as long as the XML file is at a readable URL I should be able make an AJAX request for the file and use it. Is that correct? Many thanks

  • Prevent abuse of public HTTP directory meant for images

    - by sutre
    The situation: Each user has their own public HTTP directory, meant for images only. This could easily be abused by users using it to serve large files, wasting bandwidth. The question: Is there any fairly simple way to prevent this abuse? Either by allowing the webserver to only images to be served, restricting size, or some other method.

  • Checking an empty Core Data relationship (SQLite)

    - by rwat
    I have a to-many relationship in my data model, and I'd like to get all the objects that have no corresponding objects in the relationship. For example: Customer - Purchases I want to get all Customers that have 0 Purchases. I've read somewhere that I could use "Purchases[SIZE] = 0", but this gives me an unsupported function expression error, which I think means it doesn't work with a SQLite backing store (which I don't want to switch from, due to some performance constraints). Any ideas?

  • Why use buffers to read/write Streams

    - by James Hay
    Following reading various questions on reading and writing Streams, all the various answers define something like this as the correct way to do it: private void CopyStream(Stream input, Stream output) { byte[] buffer = new byte[16 * 1024]; int read; while ((read = input.Read(buffer, 0, buffer.Length)) > 0) { output.Write(buffer, 0, read); } } Two questions: Why read and write in these smaller chunks? What is the significance of the buffer size used?

  • Best options for image resizing

    - by Claudio Redi
    Hi, I have resize images exceeding a max size. Methods I tried so far are not good enough :-( System.Drawing.Image.GetThumbnailImage generates very poor quality images in general. Playing with options like this one I can generate better images in quality but heavier than the original one. Probably the second option (or something similar) is the best option and I would need to resize using the proper options. Any advice?

  • proper fill an image larger than screen

    - by madcat
    what I wanted to achieve here is simply fit the image width to the screen on both orientations and use UIScrollView to just allow scroll vertically to see the whole image. both viewController and view are created pragmatically. the image loaded is larger than screen on both width and height. here is the related code in my viewController: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)loadView { UIScreen *screen = [UIScreen mainScreen]; CGRect rect = [screen applicationFrame]; self.view = [[UIView alloc] initWithFrame:rect]; self.view.contentMode = UIViewContentModeScaleAspectFill; self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; UIImage *img=[[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"image" ofType:@"png"]]; UIImageView *imgView =[[UIImageView alloc] initWithImage:img]; [img release]; imgView.contentMode = UIViewContentModeScaleAspectFill; imgView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.view addSubview:imgView]; [imgView release]; } tried all combinations for both contentMode above, did not give me correct result. the most close I am getting now: I manually resize imgView in loadView, portrait mode would display correctly since app always starts with portrait mode, but in landscape mode, the width fits correctly, but image is centered vertically rather than top aligned. if I add the imgView to a scrollView, in landscape mode it looks like contentSize is not set to full image size. but when I scroll bounce I can see the image is there in full size. question: why I need to resize it manually? in landscape mode how and where I can 'move' the imgView, so imgView.frame.origin is (0,0) and works correctly with a scroll view? Thanks! UPDATE: I added: imgView.clipsToBounds = YES; and find out in landscape mode the image bounds is smaller than screen in height. so the question becomes how to have the image view keeps original ratio (thus shows the full image always) when rotated to landscape? do I need to manually resize it after rotation again?

  • Centering fonts in VB6

    - by James Musser
    How do you determine the length of a string of text in Arial Bold font, and then center it in VB6? If not here, can you point me in a direction where I might be able to find this information? We're not using a "label" or "picture box" do print the text to the screen. We are sizing the text on the fly, and allowing the user to scale the size of our application to their liking. We write the text to screen using code.

  • WCF: intercept message send/receive progress in client

    - by Cullen Tsering
    Hello gurus, I have a desktop application sending/receiving messages (not files) to/from a WCF service. How do I intercept the total size of the message to be transferred and receive feedback (number of bytes transferred) during the transmission so a progress bar maybe displayed to the desktop app user? How many approaches are there? What is the best one given my application scenario? Any comments or suggestions will be greatly appreciated, Cullen

  • Determining if Memory Pointer is Valid - C++

    - by Jim Fell
    It has been my observation that if free( ptr ) is called where ptr is not a valid pointer to system-allocated memory, an access violation occurs. Let's say that I call free like this: LPVOID ptr = (LPVOID)0x12345678; free( ptr ); This will most definitely cause an access violation. Is there a way to test that the memory location pointed to by ptr is valid system-allocated memory? It seems to me that the the memory management part of the Windows OS kernel must know what memory has been allocated and what memory remains for allocation. Otherwise, how could it know if enough memory remains to satisfy a given request? (rhetorical) That said, it seems reasonable to conclude that there must be a function (or set of functions) that would allow a user to determine if a pointer is valid system-allocated memory. Perhaps Microsoft has not made these functions public. If Microsoft has not provided such an API, I can only presume that it was for an intentional and specific reason. Would providing such a hook into the system prose a significant threat to system security? Situation Report Although knowing whether a memory pointer is valid could be useful in many scenarios, this is my particular situation: I am writing a driver for a new piece of hardware that is to replace an existing piece of hardware that connects to the PC via USB. My mandate is to write the new driver such that calls to the existing API for the current driver will continue to work in the PC applications in which it is used. Thus the only required changes to existing applications is to load the appropriate driver DLL(s) at startup. The problem here is that the existing driver uses a callback to send received serial messages to the application; a pointer to allocated memory containing the message is passed from the driver to the application via the callback. It is then the responsibility of the application to call another driver API to free the memory by passing back the same pointer from the application to the driver. In this scenario the second API has no way to determine if the application has actually passed back a pointer to valid memory.

  • How does compiler understand the pointer type?

    - by Narek
    How c++ compiler understands the pointer type? As I know pointer has a size equal to WORD of the OS (32 or 64). So does it store dome info in that 32(or 64) bits about type? Just because you can not have a pointer on one type and assign to that pointer another pointer with a different type.
