    Hi I keep getting SQL syntax error when i'm running my code in php, however when i remove the variables and do it manually in MYSQL, not a problem. I've tried 2 different versions of query one with (') and other with (") and nothing. Could you please help?

  • Why doesn't `unity --reset` work?

    - by Elshaer
    I want to reset Unity. But when I type unity --reset I get the following error: Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Compiz (opengl) - Fatal: glXCreateContext failed Compiz (bailer) - Info: Ensuring a shell for your session ... I am not using Compiz! I am using Metacity. Thanks a lot :) EDIT: I am using Unity. And I want to reset it as the sidebar is always shown when I am viewing my desktop (although it hides automatically if I am using other applications) and Alt+Tab switches the windows in a different, poor way (not the default one of Ubuntu 11.10).

  • Confusion over manual/automatic sizing of Flash Sprite Objects

    - by John
    If I have a custom class subclassing Sprite and it draws some simple objects, how does this work with respect to the Sprite.width & Sprite.height properties? It seems I can draw (for example) a rectangle of any size, bigger than the Sprite size. Similarly if I set the width/height properties, what happens to the content already drawn? As a use-case, I might have a stick-man which is drawn as a set of lines, I want to set the man's height and the rendering is scaled to this. Are there any issues with width/height being auto-calculated or am I misunderstanding what these properties actually mean?

  • Why is this javascript function so slow on Firefox?

    - by macrael
    This function was adapted from the website: http://eriwen.com/javascript/measure-ems-for-layout/ function getEmSize(el) { var tempDiv = document.createElement("div"); tempDiv.style.height = "1em"; el.appendChild(tempDiv); var emSize = tempDiv.offsetHeight; el.removeChild(tempDiv); return emSize; } I am running this function as part of another function on window.resize, and it is causing performance problems on Firefox 3.6 that do not exist on current Safari or Chrome. Firefox's profiler says I'm spending the most time in this function and I'm curious as to why that is. Is there a way to get the em size in javascript without doing all this work? I would like to recalculate the size on resize incase the user has changed it.

  • How big can a SQL Server row be before it's a problem?

    - by John Leidegren
    Occasionally I run into this limitation using SQL Server 2000 that a row size can not exceed 8K bytes. SQL Server 2000 isn't really state of the art, but it's still in production code and because some tables are denormalized that's a problem. However, this seems to be a non issue with SQL Server 2005. At least, it won't complain that row sizes are bigger than 8K, but what happens instead and why was this a problem in SQL Server 2000? Do I need to care about my rows growing? Should I try and avoid large rows? Are varchar(max) and varbinary(max) a solution or expensive, in terms of size in database and/or CPU time? Why do I care at all about specifying the length of a particular column, when it seems like it's just a matter of time before someones going to hit that upper limit?

  • Popper Email Notifier not working

    - by Joel
    Using Maverick 64bit I downloaded Popper Email Notifier today. Installed it from the v023 deb. https://launchpad.net/popper I configured it, and the TEST tab shows I configured everything properly. I can't get Popper to appear in the notification menu. I have restarted gnome-pannel, restarted my computer, reinstalled the app. No luck. I checked the /usr/share/indicators/messages/applications/ folder, and there's only the defaults there. Anyone know how to fix this? Even if someone knows what file I can drop into that folder to make it work that'd be great. Edit: I wonder if it's because I removed the evolution-indicator package? Thanks!

  • Issue when rotating a UIScrollView

    - by leachianus.gecko
    I am having issues trying to get the pageControl sample code to work with rotation. I managed to get it to rotate but it does not visually load correctly until I start to scroll (then it works fine). Any Idea on how I can fix this problem? Here is a link to the project if you want to see it in action. This code is based off the PageControl example apple has provided. here is the code: #import "ScrollingViewController.h" #import "MyViewController.h" @interface ScrollingViewController (PrivateMethods) - (void)loadScrollViewWithPage:(int)page; @end @implementation ScrollingViewController @synthesize scrollView; @synthesize viewControllers; - (void)viewDidLoad { amount = 5; [super viewDidLoad]; [self setupPage]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [scrollView release]; } - (void)dealloc { [super dealloc]; } - (void)setupPage { NSMutableArray *controllers = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < amount; i++) { [controllers addObject:[NSNull null]]; } self.viewControllers = controllers; [controllers release]; // a page is the width of the scroll view scrollView.pagingEnabled = YES; scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * amount, 200); scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = NO; scrollView.scrollsToTop = NO; scrollView.delegate = self; [self loadScrollViewWithPage:0]; [self loadScrollViewWithPage:1]; } #pragma mark - #pragma mark UIScrollViewDelegate stuff - (void)scrollViewDidScroll:(UIScrollView *)_scrollView { if (pageControlIsChangingPage) { return; } /* * We switch page at 50% across */ CGFloat pageWidth = _scrollView.frame.size.width; int dog = floor((_scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1; // pageControl.currentPage = page; [self loadScrollViewWithPage:dog - 1]; [self loadScrollViewWithPage:dog]; [self loadScrollViewWithPage:dog + 1]; } - (void)loadScrollViewWithPage:(int)page { if (page < 0) return; if (page >= amount) return; MyViewController *controller = [viewControllers objectAtIndex:page]; if ((NSNull *)controller == [NSNull null]) { controller = [[MyViewController alloc] initWithPageNumber:page]; [viewControllers replaceObjectAtIndex:page withObject:controller]; [controller release]; } if (nil == controller.view.superview) { CGRect frame = scrollView.frame; frame.origin.x = frame.size.width * page; frame.origin.y = 0; controller.view.frame = frame; [scrollView addSubview:controller.view]; } } - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { [self setupPage]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return YES; } @end

  • Game Objects Talking To Each Other

    - by PhilCK
    What is a good way of dealing with objects and having them talk to each other? Up until now all my games hobby/student have been small so this problem was generally solved in a rather ugly way, which lead to tight integration and circular dependencies. Which was fine for the size of projects I was doing. However my projects have been getting bigger in size and complexity and now I want to start re-using code, and making my head a simpler place. The main problem I have is generally along the lines of Player needs to know about the Map and so does the Enemy, this has usually descended into setting lots of pointers and having lots of dependencies, and this becomes a mess quickly. I have thought along the lines of a message style system. but I cant really see how this reduces the dependencies, as I would still be sending the pointers everywhere. Thanks. PS: I guess this has been discussed before, but I don't know what its called just the need I have.

  • Converting a Matrix to a grid of colors

    - by Zach
    I'm currently making a console application in C# (will be going to a Windows Form application in the future. Sooner if needed). My current objective is to have a matrix (current size 52x42) be exported as an image (bitmap, jpeg, png, I'm flexible) where each value in the matrix (0, 1, 2, 3) is portrayed as a white, black, blue, or red square of size 20px x 20px with a grid 1px wide seperating each 'cell'. Can this even be done in a console application, and if so how? If not, what would I need to get it working in a Windows Form application?

  • Drawing Image onto Canvas Stretches Image?

    - by Fred Finkle
    I have this code (stolen from the web): function readIt() { var reader = new FileReader(); reader.onload = (function(e) { var img = new Image(); img.src = e.target.result; var c = document.getElementById("canvas"); var ctx = c.getContext("2d"); ctx.drawImage(img, 0, 0); } ); reader.readAsDataURL(document.getElementById('userImage').files[0]); } Which works up to a point. The canvas's width and height are set to the size of the image, but only the top left of the image appears - It appears to be stretched so it fits all the space allocated to the canvas (enough to display the whole image - 615px x 615px). If I add an <img> element sized the same size as the canvas and point the src to the image in the file system it appears perfect. I'm using Chrome, but it appears the same in Firefox. Thanks in advance.

  • jQuery resize event for div children

    - by Frank Michael Kraft
    $("div.content-left > *, div.content-main > *" ).live('resize',function(){alert("Size changed")}); does not work, because the resize event only applies to window resizes. But in my case the divs change size late, because the content is loaded late by an ajax request - or by clicking a panel menu. I definatley need to avoid to register on all individual events of the children (ajax, click), because that can be very many different events and then it is not maintainable.

  • Continuously reading from a stream in C#?

    - by Damien Wildfire
    I have a Stream object that occasionally gets some data on it, but at unpredictable intervals. Messages that appear on the Stream are well-defined and declare the size of their payload in advance (the size is a 16-bit integer contained in the first two bytes of each message). I'd like to have a StreamWatcher class which detects when the Stream has some data on it. Once it does, I'd like an event to be raised so that a subscribed StreamProcessor instance can process the new message. Can this be done with C# events without using Threads directly? It seems like it should be straightforward, but I can't get quite get my head around the right way to design this.

  • How do I fix the audio on my laptop. model Fujitsu B6220

    - by user89756
    I reinstalled Ubuntu 12.04 on my laptop because the Unity desktop was freezing. Reinstalling 12.04 seems to have fixed the freezing problem, but now the audio does not work. When I go to SettingsAudio and under the Output tab it only has the option for Digital Output. There is no option for Analog Output. The sound card show up under lspci as: "00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)" What would be the command to reinstall the audio subsystem? If that would fix it...

  • How can I make these Google Analytics numbers add up? (Frequency & Recency)

    - by Joe
    Here's a screen shot from Google Analytics. It's my last months traffic, and this is the 'Frequency & Recency' tab. So I believe that if I add up all the numbers under 'visits' I get 11,432, which is right, and if I add up all the numbers under 'pageviews' I get 14,785 and that's right as well. But, let's take the last line - the last line appears to say that 71 people, visited more than 51 times each, and they viewed a total of 243 pages between them - that doesn't seam to make any sense - did they view 9% of a page each time? So that's clearly wrong - what's the error in my calculation?

  • How are files (especially audio files) organized internally?

    - by mystify
    I try to grok that: Apple is talking about "packets" in audio files, and there is a fancy function called AudioFileReadPackets which takes a lot of arguments. One of them specifies the "start packet", and another one the number of packets which you want to read. So I imagine an audio file to look like this, internally: It's made up of a lot of packets. If it's an audio file which has an variable bit rate format, then every packet may have a different size. If the file has an constant bit rate format, then every packet is the same size. So an audio file is like a truck full of boxes, and every box contains some interesting stuff. Is that correct? Does it apply to any kind of file? Is this how files actually look like?

  • const member functions can call const member functions only?

    - by Abhi
    Hi all. Do const member functions call only const member functions? class Transmitter{ const static string msg; mutable int size; public: void xmit() const{ size = compute(); cout<<msg; } private: int compute() const{return 5;} }; string const Transmitter::msg = "beep"; int main(){ Transmitter t; t.xmit(); return EXIT_SUCCESS; } If i dont make compute() a const, then the compiler complains. Is it because since a const member function is not allowed to modify members, it wont allow any calls to non-consts since it would mean that the const member function would be 'indirectly' modifying the data members?

  • How to speed up saving a UIImagePickerController image from the camera to the filesystem via UIImagePNGRepresentation()?

    - by kazuhito0000
    I'm making an applications that let users take a photo and show them both in thumbnail and photo viewer. I have NSManagedObject class called photo and photo has a method that takes UIImage and converts it to PNG using UIImagePNGRepresentation() and saves it to filesystem. After this operation, resize the image to thumbnail size and save it. The problem here is UIImagePNGRepresentation() and conversion of image size seems to be really slow and I don't know if this is a right way to do it. Tell me if anyone know the best way to accomplish what I want to do. Thank you in advance.
