  • buttons and menu items in cocos2d/objective-c

    - by peter61
    In my app, I'd like a method called whenever the user taps the screen (anywhere on the screen). Normally, I'd make a transparent UIButton that covers the whole screen. If I'm using the cocos2d framework, what's the best way to do this? Is it good practice to still use UIButtons? I've been reading about MenuItems but haven't found an easy way to make one giant fully transparent menu item? Thanks.

  • How to display QuickContact card from widget

    - by alejom99
    I have a widget that displays the picture of some of my contacts and I would like to display the QuickContact card when the user taps on one of the pictures. I know I should be using the method ContactsContract.QuickContact.showQuickContact(), but it requires a View or a Rect as one of the input parameters. My problem is that Widgets only have RemoteViews, so I'm no sure what to pass as the View or Rect parameter. Any ideas would be appreciated.

  • Animation in a table view cell

    - by theomen
    I'm not sure if it is possible to achieve, but my costumer wants that when user taps a table view cell, an animation of a UIView sliding from left to right is committed, leaving the content under the UIView visible. My concern is about how to trigger gesture recognizer added to the upper UIVIew for the animation and do not enter in conflict with didSelectRowatIndex: table view delegate method. Is it possible to achieve? Mant thanks!

  • Windows 8.1 touchpad three-finger-multitouch gesture gone

    - by THEVAN3D
    Couple of days ago, i installed the Windows 8.1 Pro WMC and all of a sudden the touchpad gesture, which worked like a charm back in Win 8.1 preview, Win 8 and even Win 7, just stopped working. I am talking about the "Three Finger Flick" feature, which is used to go back and forward in folders and/or internet browsers at first i didnt even have the left edge pull feature, but then i added some values in this key into regedit, and now i have it [HKEY_CURRENT_USER\Software\Synaptics\SynTPEnh\ZoneConfig\TouchPadPS2\Left Edge Pull] I Googled that, i didnt know what to do by myself and i dont know where to write and what to write anything in order to get the three finger flick back too I installed various versions of drivers starting from about version 15 to the version 17.0.8.0 (the one that i currently have), and even though i have all the other gestures, taps and swipes working they are not in the device settings, there is no multitouch gestures in device settings so thats why i guess i have to write something in regedit, but again, i dont know what to write, and where to write. please help me if you can

  • [GEEK SCHOOL] Network Security 1: Securing User Accounts and Passwords in Windows

    - by Matt Klein
    This How-To Geek School class is intended for people who want to learn more about security when using Windows operating systems. You will learn many principles that will help you have a more secure computing experience and will get the chance to use all the important security tools and features that are bundled with Windows. Obviously, we will share everything you need to know about using them effectively. In this first lesson, we will talk about password security; the different ways of logging into Windows and how secure they are. In the proceeding lesson, we will explain where Windows stores all the user names and passwords you enter while working in this operating systems, how safe they are, and how to manage this data. Moving on in the series, we will talk about User Account Control, its role in improving the security of your system, and how to use Windows Defender in order to protect your system from malware. Then, we will talk about the Windows Firewall, how to use it in order to manage the apps that get access to the network and the Internet, and how to create your own filtering rules. After that, we will discuss the SmartScreen Filter – a security feature that gets more and more attention from Microsoft and is now widely used in its Windows 8.x operating systems. Moving on, we will discuss ways to keep your software and apps up-to-date, why this is important and which tools you can use to automate this process as much as possible. Last but not least, we will discuss the Action Center and its role in keeping you informed about what’s going on with your system and share several tips and tricks about how to stay safe when using your computer and the Internet. Let’s get started by discussing everyone’s favorite subject: passwords. The Types of Passwords Found in Windows In Windows 7, you have only local user accounts, which may or may not have a password. For example, you can easily set a blank password for any user account, even if that one is an administrator. The only exception to this rule are business networks where domain policies force all user accounts to use a non-blank password. In Windows 8.x, you have both local accounts and Microsoft accounts. If you would like to learn more about them, don’t hesitate to read the lesson on User Accounts, Groups, Permissions & Their Role in Sharing, in our Windows Networking series. Microsoft accounts are obliged to use a non-blank password due to the fact that a Microsoft account gives you access to Microsoft services. Using a blank password would mean exposing yourself to lots of problems. Local accounts in Windows 8.1 however, can use a blank password. On top of traditional passwords, any user account can create and use a 4-digit PIN or a picture password. These concepts were introduced by Microsoft to speed up the sign in process for the Windows 8.x operating system. However, they do not replace the use of a traditional password and can be used only in conjunction with a traditional user account password. Another type of password that you encounter in Windows operating systems is the Homegroup password. In a typical home network, users can use the Homegroup to easily share resources. A Homegroup can be joined by a Windows device only by using the Homegroup password. If you would like to learn more about the Homegroup and how to use it for network sharing, don’t hesitate to read our Windows Networking series. What to Keep in Mind When Creating Passwords, PINs and Picture Passwords When creating passwords, a PIN, or a picture password for your user account, we would like you keep in mind the following recommendations: Do not use blank passwords, even on the desktop computers in your home. You never know who may gain unwanted access to them. Also, malware can run more easily as administrator because you do not have a password. Trading your security for convenience when logging in is never a good idea. When creating a password, make it at least eight characters long. Make sure that it includes a random mix of upper and lowercase letters, numbers, and symbols. Ideally, it should not be related in any way to your name, username, or company name. Make sure that your passwords do not include complete words from any dictionary. Dictionaries are the first thing crackers use to hack passwords. Do not use the same password for more than one account. All of your passwords should be unique and you should use a system like LastPass, KeePass, Roboform or something similar to keep track of them. When creating a PIN use four different digits to make things slightly harder to crack. When creating a picture password, pick a photo that has at least 10 “points of interests”. Points of interests are areas that serve as a landmark for your gestures. Use a random mixture of gesture types and sequence and make sure that you do not repeat the same gesture twice. Be aware that smudges on the screen could potentially reveal your gestures to others. The Security of Your Password vs. the PIN and the Picture Password Any kind of password can be cracked with enough effort and the appropriate tools. There is no such thing as a completely secure password. However, passwords created using only a few security principles are much harder to crack than others. If you respect the recommendations shared in the previous section of this lesson, you will end up having reasonably secure passwords. Out of all the log in methods in Windows 8.x, the PIN is the easiest to brute force because PINs are restricted to four digits and there are only 10,000 possible unique combinations available. The picture password is more secure than the PIN because it provides many more opportunities for creating unique combinations of gestures. Microsoft have compared the two login options from a security perspective in this post: Signing in with a picture password. In order to discourage brute force attacks against picture passwords and PINs, Windows defaults to your traditional text password after five failed attempts. The PIN and the picture password function only as alternative login methods to Windows 8.x. Therefore, if someone cracks them, he or she doesn’t have access to your user account password. However, that person can use all the apps installed on your Windows 8.x device, access your files, data, and so on. How to Create a PIN in Windows 8.x If you log in to a Windows 8.x device with a user account that has a non-blank password, then you can create a 4-digit PIN for it, to use it as a complementary login method. In order to create one, you need to go to “PC Settings”. If you don’t know how, then press Windows + C on your keyboard or flick from the right edge of the screen, on a touch-enabled device, then press “Settings”. The Settings charm is now open. Click or tap the link that says “Change PC settings”, on the bottom of the charm. In PC settings, go to Accounts and then to “Sign-in options”. Here you will find all the necessary options for changing your existing password, creating a PIN, or a picture password. To create a PIN, press the “Add” button in the PIN section. The “Create a PIN” wizard is started and you are asked to enter the password of your user account. Type it and press “OK”. Now you are asked to enter a 4-digit pin in the “Enter PIN” and “Confirm PIN” fields. The PIN has been created and you can now use it to log in to Windows. How to Create a Picture Password in Windows 8.x If you log in to a Windows 8.x device with a user account that has a non-blank password, then you can also create a picture password and use it as a complementary login method. In order to create one, you need to go to “PC settings”. In PC Settings, go to Accounts and then to “Sign-in options”. Here you will find all the necessary options for changing your existing password, creating a PIN, or a picture password. To create a picture password, press the “Add” button in the “Picture password” section. The “Create a picture password” wizard is started and you are asked to enter the password of your user account. You are shown a guide on how the picture password works. Take a few seconds to watch it and learn the gestures that can be used for your picture password. You will learn that you can create a combination of circles, straight lines, and taps. When ready, press “Choose picture”. Browse your Windows 8.x device and select the picture you want to use for your password and press “Open”. Now you can drag the picture to position it the way you want. When you like how the picture is positioned, press “Use this picture” on the left. If you are not happy with the picture, press “Choose new picture” and select a new one, as shown during the previous step. After you have confirmed that you want to use this picture, you are asked to set up your gestures for the picture password. Draw three gestures on the picture, any combination you wish. Please remember that you can use only three gestures: circles, straight lines, and taps. Once you have drawn those three gestures, you are asked to confirm. Draw the same gestures one more time. If everything goes well, you are informed that you have created your picture password and that you can use it the next time you sign in to Windows. If you don’t confirm the gestures correctly, you will be asked to try again, until you draw the same gestures twice. To close the picture password wizard, press “Finish”. Where Does Windows Store Your Passwords? Are They Safe? All the passwords that you enter in Windows and save for future use are stored in the Credential Manager. This tool is a vault with the usernames and passwords that you use to log on to your computer, to other computers on the network, to apps from the Windows Store, or to websites using Internet Explorer. By storing these credentials, Windows can automatically log you the next time you access the same app, network share, or website. Everything that is stored in the Credential Manager is encrypted for your protection.

  • Sign of a Good Game

    - by Matt Christian
    (Warning: This post contains spoilers about SILENT HILL 2.  If you haven't played this game, you are dumb) What is one sign of a great game? One of the signs I realized recently is when a game continues to stun and surprise you years and years after you've played and beaten it.  As a major Silent Hill fan, I recently was reminded of Silent Hill 2 and even though see it as one of my favorite Silent Hill games, there are still things I'm learning about it that are neat little additions that add to the atmosphere (atmosphere also makes a great game!). For instance, when you start the game you are given a letter by your wife who has been deceased for years and years.  You are directed to Silent Hill and start treking through hell all by your lonesome (with the exception of a few psychos).  As you continue through the game, pieces of the letter begin to fade and disappear until eventually it is completely non-existent, thus implying the letter was never real and the letter was a delusion you created. Another example is the game's use of imagery the player knows about but might not notice at first.  For me, the most apparent of these was the dress you find near the start when you find the flashlight, which is the same dress you see Mary (your wife) wearing in the flashback sequences.  However, one thing I didn't know was that several deceased bodies you encounter laying around Silent Hill are actually the body of the main character (James) which invokes an idea you've seen that body before but can't pinpoint where... It's amazing to see a game go to such unique lengths to provide a psychological horror game.  Sure, all the dead bodies could be randomly modelled and the dress could be any ol' dress, but just the idea of your brain knowing something deep down but you can't pinpoint it is a really unique idea.  In my opinion, it ties less into subconscious and more into natural tendencies, it taps into the fear hidden inside us all.

  • T-Mobile releases an App to unlock mobile devices

    - by Gopinath
    T-Mobile is in no mood to stop innovating and outsmarting its rival wireless network providers in USA. Its been talk of the wireless community and rightly deserves the space for its push to make wireless providers more consumer friendly in USA. Just couple of days after US Government passed a law that made unlocking smartphones legal in USA, T-Mobile released an Android App to make unlocking smartphone as easy as few taps. The app aptly named Device Unlock is available in Android Play Store and at the moment it can unlock only Samsung Galaxy Avant smartphones. The app lets you either temporarily unlock your smartphone for 30 days(very helpful for those who travel and wants to use their phone with other carriers) or send a request to T-Mobile to permanently unlock the device for ever. When user tries to unlock the device, the App verifies the user account to make sure that the account complies with T-Mobile rules. If the rule check passes, the app automatically unlocks the phone. The process is very simple and T-Mobile users are going to love this; the other carrier users would envy to have such a simple process to unlock smartphones. Though this app is available for just Android Play Store and works only Samsung Galaxy Avant smartphone, it looks T-Mobile is testing out this feature on small set of users first to learn and improve unlocking process. Hope to see this app able unlock all T-Mobile devices soon.

  • PC On/Off Time Charts Windows Uptime; No Logging Necessary

    - by Jason Fitzpatrick
    Windows: PC On/Off Time is a graphical tool that displays your PC’s uptime, downtime, errors, and more all in a clear and portable package. One of the hassles of using logging tools is that you usually have to enable the logging and then wait for results to pile up before seeing anything useful (such as when you turn on the logging on your router). PC On/Off Time taps right into the event logs your Windows PC is already keeping so you get immediate access to your uptime history. If you look at the screenshot above you can see an accurate picture of the last few weeks of uptime on my computer. October 23-24 I didn’t boot down my PC, the rest of the time I hibernated it overnight when I wasn’t using it, November 1st I installed an SSD (you can see the burst of reboots and short uptimes) and then November 9th there was a brief power outage that caused an unexpected stop (the red arrows on the timeline for the 9th). The free version offers a three-week peek back into your uptime history (upgrade to the Pro version for $12.75 or for free using Trial Pay to unlock your completely uptime history).PC On/Off Time is Windows only.

  • How to account for speed of the vehicle when shooting shells from it?

    - by John Murdoch
    I'm developing a simple 3D ship game using libgdx and bullet. When a user taps the mouse I create a new shell object and send it in the direction of the mouse click. However, if the user has tapped the mouse in the direction where the ship is currently moving, the ship catches up to the shells very quickly and can sometimes even get hit by them - simply because the speed of shells and the ship are quite comparable. I think I need to account for ship speed when generating the initial impulse for the shells, and I tried doing that (see "new line added"), but I cannot figure out if what I'm doing is the proper way and if yes, how to calculate the correct coefficient. public void createShell(Vector3 origin, Vector3 direction, Vector3 platformVelocity, float velocity) { long shellId = System.currentTimeMillis(); // hack ShellState state = getState().createShellState(shellId, origin.x, origin.y, origin.z); ShellEntity entity = EntityFactory.getInstance().createShellEntity(shellId, state); add(entity); entity.getBody().applyCentralImpulse(platformVelocity.mul(velocity * 0.02f)); // new line added, to compensate for the moving platform, no idea how to calculate proper coefficient entity.getBody().applyCentralImpulse(direction.nor().mul(velocity)); } private final Vector3 v3 = new Vector3(); public void shootGun(Vector3 direction) { Vector3 shipVelocity = world.getShipEntities().get(id).getBody().getLinearVelocity(); world.getState().getShipStates().get(id).transform.getTranslation(v3); // current location of our ship v3.add(direction.nor().mul(10.0f)); // hack; this is to avoid shell immediately impacting the ship that it got shot out from world.createShell(v3, direction, shipVelocity, 500); }

  • Supporting copy 'n paste in your Windows Phone app

    - by Daniel Moth
    Some Windows Phone 7 owners already have the NoDo update, and others are getting it soon. This update brings, among other things, copy & paste support for text boxes. The user taps on a piece of text (and can drag in either direction to select more/less words), a popup icon appears that when tapped copies the text to the clipboard, and then at any app that shows the soft input panel there is an icon option to paste the copied text into the associated textbox. For more read this 'how to'. Note that there is no programmatic access to the clipboard, only the end user experience I just summarized, so there is nothing you need to do for your app's textboxes to support copy & paste: it just works. The only issue may be if in your app you use static TextBlock controls, for which the copy support will not appear, of course. That was the case with my Translator by Moth app where the translated text appears in a TextBlock. So, I wanted the user to be able to copy directly from the translated text (without offering an editable TextBox for an area where user input does not make sense). Take a look at a screenshot of my app before I made any changes to it. I then made changes to it preserving the look and feel, yet with additional copy support (see screenshot on the right)! So how did I achieve that? Simply by using my co-author's template (thanks Peter!): Copyable TextBlock for Windows Phone.   (aside: in my app even without this change there is a workaround, the user could use the "swap" feature to swap the source and target, so they can copy from the text box) Comments about this post welcome at the original blog.

  • Trouble with touch events on iPhone

    - by MrDatabase
    I'm making a simple 2D game for iPhone. Think of the game as a ball on the screen that goes up while the user is touching the screen and falls down when the user stops touching the screen. The ball starts moving up in touchesBegan:withEvent and starts moving down in touchesEnded:withEvent. This works fine almost all the time. However on occasion the ball will keep moving up after the user stops touching... or the ball will keep moving down while the user is touching. Why is this happening? Just fyi the ball is drawn on a UIWindow. The taps are handled by a UIImageview subclass that's clearColor and takes up the entire screen. This "touchLayer" is also moved to the front of the window in the game loop. Any idea why this control scheme occasionally fails? Perhaps the touch events just aren't firing? Or they're fired out of order? Cheers!

  • iOS and Server: OAuth strategy

    - by drekka
    I'm trying to working how to handle authentication when I have iOS clients accessing a Node.js server and want to use services such as Google, Facebook etc to provide basic authentication for my application. My current idea of a typical flow is this: User taps a Facebook/Google button which triggers the OAuth(2) dialogs and authenticates the user on the device. At this point the device has the users access token. This token is saved so that the next time the user uses the app it can be retrieved. The access token is transmitted to my Node.js server which stores it, and tags it as un-verified. The server verifies the token by making a call to Facebook/google for the users email address. If this works the token is flagged as verified and the server knows it has a verified user. If Facebook/google fail to authenticate the token, the server tells iOS client to re-authenticate and present a new token. The iOS client can now access api calls on my Node.js server passing the token each time. As long as the token matches the stored and verified token, the server accepts the call. Obviously the tokens have time limits. I suspect it's possible, but highly unlikely that someone could sniff an access token and attempt to use it within it's lifespan, but other than that I'm hoping this is a reasonably secure method for verification of users on iOS clients without having to roll my own security. Any opinions and advice welcome.

  • Touchpad issues on HP Pavilion dm4 (can't right click)

    - by Habstinat
    Can anyone help me with my touchpad issues? I have a HP Pavilion dm4 and it has two areas on the bottom of the touchpad to designate right and left clicks. This mostly doesn't work on Ubuntu in the fact that it recognizes any taps on either tap zone as a left click. Instead, I have it set so if I tap anywhere on the pad it makes a left click. There should be, and there are, many ways in the mouse configuration window to simulate a right click using only a touchpad. None of these work. Changing mouse orientation doesn't do anything, "dwell click" also does nothing, and, the oddest part of this problem, whenever I try to turn "Simulated Secondary Click" off (it doesn't work anyways, but just to try to toggle it), the entire theme of my desktop changes to a gray Windows '95ey look. The only way to get rid of this is to close and reopen the mouse preferences window. My computer is fairly new and the Ubuntu installation is less than a day old. I didn't do anything that I think could cause this. The problem is that I can't right click. Help, please?s that I can't right click. Help, please? Afterword: I installed two scripts from http://sansmicrosoft.blogspot.com/2010/10/pavilion-dm4-1160-erratic-touchpad.html . They didn't do anything I couldn't already do, and they did not make it possible for me to right click. :(

  • iphone - UITapGestureRecognizer problem

    - by Mike
    I have two UIImageViews one as subview of the other. The subview is smaller and is centered on the screen. Both have UITapGestureRecognizer assigned and both were intended to respond to single taps. A single tap on the main view (= the area outside the subview) is fine, but a tap inside the subview is seen as the main view as a tap too. How can I have this to work independently? both views have setCancelsTouchesInView and setDelaysTouchesEnded set to NO and both have the same delegate (yes, I need to have the same delegate and cannot change that). How may I force the main view to ignore any tap on the area that belongs to its subview? thanks for any help.

  • Reference from UITableViewCell to UITableView to UINavigationController

    - by Nick
    If the user taps and holds on a Foo table view cell for 2 seconds, a modal view should be shown. The modal view is also displayed when a new Foo is added to the cell. The modal view's delegate protocol is implemented by the parent UITableView subclass. My tap and hold detection code is in the Foo UITableViewCell class. I'm having difficulty referencing the parent tableview's navigation controller to display the modal view. FooModalViewController *modalController = [[FooModalViewController alloc] initWithNibName:@"FooModalViewController" bundle:nil]; FooTableViewController *tableView = (FooTableViewController *) self.superview; foo.delegate = tableView; Seems OK but I'm having problems referencing the navigation controller that contains the tableview.. The code below builds OK but throws an exception - NSOBject DoesNotRecognizeSelector. UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:modalController]; [[tableView.navigationController] presentModalViewController:navigationController animated:YES]; I think that perhaps my design is flawed..?

  • How can I manage the height of android spinner items?

    - by rushinge
    I have an android spinner that's populated by a list of strings using an ArrayAdapter and it operates fine, however because of the way the spinner is displayed I'm running into a display height problem with the list items. At first glance it would seem that the ArrayAdapter can use a single layout for displaying options which leads to the problem I'm having. When displaying the current item in the spinner (when the user is not selecting a new item from the list) the spinner pads the text so that the spinner is a reasonable size for clicking on. However when the user taps on it and brings up the list to select a new item, the list items presented are way to small height-wise. If I use an item layout that presents the list items at a reasonable height, then the spinner itself becomes exorbitantly huge due to it's own padding of the list item. Any ideas on how I can manage the height of these two item display modes so that effectively they display with the same height value instead of the spinner height being larger than the list item display height?

  • ScatterViewItems Containing Surface Interactive Elements

    This is an age old problem of interactive elements inside interactive elements, but I want a ScatterViewItem to contain other surface interactive elements such as a SurfaceButton or SurfaceCheckBox. I've got all my elements in there and they react to taps etc. The problem is that I only get the normal ScatterView behavior once I click on an area that does not contain a control. Is there an elegant solution to allow dragging even when the contact is on a SurfaceButton or SurfaceCheckbox? e.g. <s:ScatterView > <Grid Width="200" Height="200"> <s:SurfaceButton /> </Grid> </s:ScatterView>
