  • Why is my web page left-aligned on iPad?

    - by Andrew
    I recently built a site and centered it using margin: 0 auto. I also wrapped elements in a .wrapper class with a width set to 960px and then had the parent element extend across the whole browser. When I view the Brands screen on an iPad though, the site is left-aligned and does not extend across the whole window. Any thoughts to why this might be happening, and how to correct it? See below for a screenshot:

  • How do you make the scale animation begin at the middle of the object instead of the top left?

    - by Roy
    What I am trying to accomplish: 10 percent increase scale transformation of a rectangle via Silverlight storyboard animation. What I currently doing: While in Expression Blend 3, I created a rectangle, created a storyboard, and created the scale transformation. The preview looked correct because the increase in scale begins in the middle of the object. When I run the project the scale transformation begins at the top left. Is there some piece of code missing? Here is my current code: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="TestingGroundsWebsite.MainPage" Width="640" Height="480"> <UserControl.Resources> <Storyboard x:Name="RectangleAppear"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="rectangle" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)"> <EasingDoubleKeyFrame KeyTime="00:00:00" Value="0.1"/> <EasingDoubleKeyFrame KeyTime="00:00:01" Value="1.1"/> <EasingDoubleKeyFrame KeyTime="00:00:02" Value="1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="rectangle" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)"> <EasingDoubleKeyFrame KeyTime="00:00:00" Value="0.1"/> <EasingDoubleKeyFrame KeyTime="00:00:01" Value="1.1"/> <EasingDoubleKeyFrame KeyTime="00:00:02" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </UserControl.Resources> <Canvas x:Name="LayoutRoot" Background="White"> <Rectangle x:Name="rectangle" Fill="#FFE80000" Stroke="Black" Height="75" Width="76" Canvas.Left="227" Canvas.Top="167" RenderTransformOrigin="0.5,0.5"> <Rectangle.RenderTransform> <TransformGroup> <ScaleTransform/> <SkewTransform/> <RotateTransform/> <TranslateTransform/> </TransformGroup> </Rectangle.RenderTransform> </Rectangle> </Canvas> </UserControl> Thanks

  • How can I left-justify numerical output in fortran?

    - by mishaF
    I am writing some simple output in fortran, but I want whitespace delimiters. If use the following statement, however: format(A20,ES18.8,A12,ES18.8) I get output like this: p001t0000 3.49141273E+01obsgp_oden 1.00000000E+00 I would prefer this: p001t0000 3.49141273E+01 obsgp_oden 1.00000000E+00 I tried using negative values for width (like in Python) but no dice. So, is there a way to left-justify the numbers? Many thanks in advance!

  • jquery position changing with .css() behaving strange

    - by 11684
    I tried to make a moving img, and it works partially. If I press the right, up or down button, it moves right, up or down. But, if I press the left button, it jumps very fast very far to the right, and then back to the left and doesn't stop moving (I believe. I said it was fast). JSFiddle; Javascript: $(document).ready(function() { var up = down = left = right = false; var top = 100, left = 500; $("body").on("keydown", function(e) { if(e.keyCode == 39) {e.preventDefault(); if (right == false) right = setInterval(moveRight, 80);} else if(e.keyCode == 37) {e.preventDefault(); if (left == false) left = setInterval(moveLeft, 80);} else if(e.keyCode == 38) {e.preventDefault(); if (up == false) up = setInterval(moveUp, 80);} else if(e.keyCode == 40) {e.preventDefault(); if (down == false) down = setInterval(moveDown, 80);} }); $("body").on("keyup", function(e) { if(e.keyCode == 39) {clearInterval(right); right = false;} else if(e.keyCode == 37) {clearInterval(left); left = false;} else if(e.keyCode == 38) {clearInterval(up); up = false;} else if(e.keyCode == 40) {clearInterval(down); down = false;} }); function moveUp() { top -= 2; $("#player").css("top", top + "px"); } function moveDown() { top += 2; $("#player").css("top", top + "px"); } function moveLeft() { left -= 2; $("#player").css("left", left + "px"); } function moveRight() { left += 2; $("#player").css("left", left + "px"); } }); This is probably not the best way to do this, I'm open for better suggestions. Thanks for reading!

  • Working with Joins in LINQ

    - by vik20000in
    While working with data most of the time we have to work with relation between different lists of data. Many a times we want to fetch data from both the list at once. This requires us to make different kind of joins between the lists of data. LINQ support different kinds of join Inner Join     List<Customer> customers = GetCustomerList();     List<Supplier> suppliers = GetSupplierList();      var custSupJoin =         from sup in suppliers         join cust in customers on sup.Country equals cust.Country         select new { Country = sup.Country, SupplierName = sup.SupplierName, CustomerName = cust.CompanyName }; Group Join – where By the joined dataset is also grouped.     List<Customer> customers = GetCustomerList();     List<Supplier> suppliers = GetSupplierList();      var custSupQuery =         from sup in suppliers         join cust in customers on sup.Country equals cust.Country into cs         select new { Key = sup.Country, Items = cs }; We can also work with the Left outer join in LINQ like this.     List<Customer> customers = GetCustomerList();     List<Supplier> suppliers = GetSupplierList();      var supplierCusts =         from sup in suppliers         join cust in customers on sup.Country equals cust.Country into cs         from c in cs.DefaultIfEmpty()  // DefaultIfEmpty preserves left-hand elements that have no matches on the right side         orderby sup.SupplierName         select new { Country = sup.Country, CompanyName = c == null ? "(No customers)" : c.CompanyName,                      SupplierName = sup.SupplierName};Vikram

  • HTML5 CSS3 layout not working

    - by John.Weland
    I have been asked by a local MMA (Mixed Martial Arts) School to help them develop a website. For the life of me I CANNOT get the layout to work correctly. When I get one section set where it should be another moves out of place! here is a pic of the layout: here The header should be a set height as should the footer the entire site at its widest point should be 1250px with the header/content area/footer and the like being 1240px the black in the picture is a scaling background to expand wider as larger resolution systems are viewing them. The full site should be a minimum-height of 100% but scale virtually as content in the target area deems necessary. My biggest issue currently is that my "sticky" footer doesn't stick once the content has stretched the content target area virtually. the Code is not pretty but here it is: HTML5 <!doctype html> <html> <head> <link rel="stylesheet" href="menu.css" type="text/css" media="screen"> <link rel="stylesheet" href="master.css" type="text/css" media="screen"> <meta charset="utf-8"> <title>Untitled Document</title> </head> <body bottommargin="0" leftmargin="0" rightmargin="0" topmargin="0"> <div id="wrap" class="wrap"><div id="logo" class="logo"><img src="images/comalogo.png" width="100" height="150"></div> <div id="header" class="header">College of Martial Arts</div> <div id="nav" class="nav"> <ul id="menu"><b> <li><a href="#">News</a></li> <li>·</li> <li><a href="#">About Us</a> <ul> <li><a href="#">The Instructors</a></li> <li><a href="#">Our Arts</a></li> </li> </ul> <li>·</li> <li><a href="#">Location</a></li> <li>·</li> <li><a href="#">Gallery</a></li> <li>·</li> <li><a href="#">MMA.tv</a></li> <li>·</li> <li><a href="#">Schedule</a></li> <li>·</li> <li><a href="#">Fight Gear</a></li></b> </div> <div id="social" class="social"> <a href="http://www.facebook.com/pages/Canyon-Lake-College-of-Martial-Arts/189432551104674"><img src="images/soc/facebook.png"></a> <a href="https://twitter.com/#!/CanyonLakeMMA"><img src="images/soc/twitter.png"></a> <a href="https://plus.google.com/108252414577423199314/"><img src="images/soc/google+.png"></a> <a href="http://youtube.com/user/clmmatv"><img src="images/soc/youtube.png"></a></div> <div id="mid" class="mid">test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br>test <br></div> <div id="footer" class="footer"> <div id="contact" style="left:0px;">tel: (830) 214-4591<br /> e: [email protected]<br /> add: 1273 FM 2673, Sattler, TX 78133<br /> </div> <div id="affiliates" style="right:0px;">Hwa Rang World Tang soo Do</div> <div id="copyright">Copyright © College of Martial Arts</div> </div> </body> </html> CSS3 -Dropdown Menu- @charset "utf-8";

  • VirtualBox reinstalling & updating has left me with Too Many Network Adapters. How Do i remove them?

    - by S3curityPlu5
    I have too many network adapters. I have had to reinstall, repair VirtualBox a few times, and I have three NICs in my laptop. I definitely don't need to have 14 bridged networking drivers though, and I cannot uninstall them. I only want to keep the new ones that came with VirtualBox 4.1.20. When I go into the registry there are tons of places with these adapters. I have searched online up to 10 pages of Google, and VirtualBox forums, and no one has mentioned this problem nor explained how to delete these annoying extra network adapters. Please offer some assistance or at least tell me how anybody else has dealt with this. I only need 1 host-only network adapter, 1 bridged networking adapter for each of my network cards. Take a look:

  • Computer crashes if left unattended AND running uTorrent, what could be?

    - by DiegoDD
    I have a weird problem in which, if I leave my computer unattended, AND I leave uTorrent open, downloading/seeding, the computer simply crashes after about 20 / 30 minutes (don't know exactly since if I leave it, and come back later, it has already restarted or has a BSOD.) If I leave the computer alone for undefined time WITHOUT uTorrent, nothing happens, and if I am constantly using the computer while using uTorrent, no problem either (I could be using it all day with uT open and it doesn't crash). So what could it be that the combination of those cases makes the computer crash? I have already checked the power management so the computer never enters stand by mode, sleep, hibernate, etc. (the only thing I do is turn off the display). A first guess is that maybe one of my external hard drives DO sleep or enters in a "low power" mode or something if I don't use the PC. but since uT is running MAYBE tries to use that drive, and makes it crash. Could that be possible? How to know for sure if the external drive does that, and to prevent it from doing so. Any more ideas of what may be causing that? Specs: Windows 7 Pro, 64-bit, 2 GB RAM. Latest version of uTorrent (although it has been happening for a while now). UPDATE: i just found out that uTorrent has Disk cache options ( preferences - advanced - disk cache ). I have no idea if that may be causing problems with my external drive, hence causing the crash.

  • Multi-level navigation controller on left-hand side of UISplitView with a small twist.

    - by user141146
    Hi. I'm trying make something similar to (but not exactly like) the email app found on the iPad. Specifically, I'd like to create a tab-based app, but each tab would present the user with a different UISplitView. Each UISplitView contains a Master and a Detail view (obviously). In each UISplitView I would like the Master to be a multi-level navigational controller where new UIViewControllers are pushed onto (or popped off of) the stack. This type of navigation within the UISplitView is where the application is similar to the native email app. To the best of my knowledge, the only place that has described a decent "splitviewcontroller inside of a uitabbarcontroller" is here: http://stackoverflow.com/questions/2475139/uisplitviewcontroller-in-a-tabbar-uitabbarcontroller and I've tried to follow the accepted answer. The accepted solution seems to work for me (i.e., I get a tab-bar controller that allows me to switch between different UISplitViews). The problem is that I don't know how to make the left-hand side of the UISplitView to be a multi-level navigation controller. Here is the code I used within my app delegate to create the initial "split view 'inside' of a tab bar controller" (it's pretty much as suggested in the aforementioned link). - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSMutableArray *tabArray = [NSMutableArray array]; NSMutableArray *array = [NSMutableArray array]; UISplitViewController *splitViewController = [[UISplitViewController alloc] init]; MainViewController *viewCont = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil]; [array addObject:viewCont]; [viewCont release]; viewCont = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; [array addObject:viewCont]; [viewCont release]; [splitViewController setViewControllers:array]; [tabArray addObject:splitViewController]; [splitViewController release]; array = [NSMutableArray array]; splitViewController = [[UISplitViewController alloc] init]; viewCont = [[Master2 alloc] initWithNibName:@"Master2" bundle:nil]; [array addObject:viewCont]; [viewCont release]; viewCont = [[Slave2 alloc] initWithNibName:@"Slave2" bundle:nil]; [array addObject:viewCont]; [viewCont release]; [splitViewController setViewControllers:array]; [tabArray addObject:splitViewController]; [splitViewController release]; // Add the tab bar controller's current view as a subview of the window [tabBarController setViewControllers:tabArray]; [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; return YES; } the class MainViewController is a UIViewController that contains the following method: - (IBAction)push_me:(id)sender { M2 *m2 = [[[M2 alloc] initWithNibName:@"M2" bundle:nil] autorelease]; [self.navigationController pushViewController:m2 animated:YES]; } this method is attached (via interface builder) to a UIButton found within MainViewController.xib Obviously, the method above (push_me) is supposed to create a second UIViewController (called m2) and push m2 into view on the left-side of the split-view when the UIButton is pressed. And yet it does nothing when the button is pressed (even though I can tell that the method is called). Thoughts on where I'm going wrong? TIA!
