  • Can I use feature detection to know if css hover works for this client?

    - by user366061
    I've got a website that provides labels when the user hovers over an image. You can see the example at: http://www.185vfx.com/ For touchscreens, I'd like to have those hints on by default (since hover isn't usually available). I'd prefer not to browser-sniff and try to maintain that list as new devices/versions arrive. Any reliable way to detect if a browser can respond to hover or otherwise know about a touchscreen user via javascript or css?

  • Enterprise Native Mobile Application Development

    - by ahsteele
    I tend to believe that developing mobile applications in an enterprise environment is best suited by developing intranet web applications. That said I have been asked to think about whether there are specific enterprise applications that could only be accomplished or would be more successful as native applications. I am curious as to what the Stack Overflow community thinks. Note: As an organization we primarily use BlackBerry devices but are other platform curious.

  • Android Emulator and adb problems

    - by Richard
    I'm having a problem in that whenever I start a emulator, either manually through the command line, or when debugging from Eclipse, it is never recognized by adb, i.e. 'adb devices' will not list it. I have to manually kill and restart adb every time I want to recognize a new emulator. Surely, something is wrong here? (I'm on Vista 64-bit)

  • How to keep iPhone app out of iPad store?

    - by Eric
    I have an iPhone app that I have started to turn into a universal app, however the process is not complete and I want to release an update to the iPhone version. I know that you can specify device capabilities in the Info.plist file to restrict your app to certain devices, but how can I do this to prevent the unfinished universal version from appearing in the iPad store? Is checking the LSRequiresiPhoneOS BOOL entry (in the Info.plist file) enough? Thanks!

  • Calculating Connection/Download Speed

    - by kdbdallas
    I have a client and server program (both in Obj-C) and I am transferring files between two devices using the programs. The transferring is working fine, but I would like to display to the user what transfer rate they are getting. So I know the total size of the file, and how much of the file has been transferred, is there a way to figure out the transfer rate from this information, and if not, what information do I need to calculate the transfer rate? Thanks

    I have a gridview and when a user selects a row I want to change the view in my multiview and display several new gridviews. A user would be clicking on a computer, and then it will display the computer stats/atached devices/etc. The new gridviews are going to need a column from the row that was selected, how do I get that? Thanks.

  • How do I aggregate activerecord model data for a specific time period?

    - by gsiener
    I'm collecting data from a system every ~10s (this time difference varies due to communication time with networked devices). I'd like to calculate averages and sums of the stored values for this activerecord model on a daily basis. All records are stored in UTC. What's the correct way to sum and average values for, e.g., the previous day from midnight to midnight EST? I can do this in sql but don't know the "rails way" to make this calculation.

  • BlackBerry specific stylesheet

    - by Luke
    We want to use the same page to service the desktop, iPhone, and BlackBerry, so we have to come up with a way for the different devices to load different stylesheets. So, is there a way to specify a stylesheet to run on BlackBerry? For example, iPhone's use the media attribute: <link media="only screen and (max-device-width: 320px)" href="style.css" ...

  • Windows Question: RunOnce/Second Boot Issues [closed]

    - by Greg
    Moved to Super User: Windows Question: RunOnce/Second Boot Issues I am attempting to create a Windows XP SP3 image that will run my application on Second Boot. Here is the intended workflow. 1) Run Image Prep Utility (I wrote) on windows to add my runonce entries and clean a few things up. 2) Reboot to ghost, make image file. 3) Package into my ISO and distribute. 4) System will be imaged by user. 5) On first boot, I have about 5 things that run, one of which includes a driver updater (I wrote) for my own specific devices. 6) One of the entries inside of HKCU/../runonce is a reg file, which adds another key to HKLM/../runonce. This is how second boot is acquired. 7) As a result of the driver updater, user is prompted to reboot. 8) My application is then launched from HKLM/../runonce on second boot. This workflow works perfectly, except for a select few legacy systems that contain devices that cause the add hardware wizard to pop up. When the add hardware wizard pops up is when I begin to see problems. It's important to note, that if I manually inspect the registry after the add hardware wizard pops up, it appears as I would expect, with all the first boot scripts having run, and it's sitting in a state I would correctly expect it to be in for a second boot scenario. The problem comes when I click next on the add hardware wizard, it seems to re-run the single entry I've added, and re-executes the runonce scripts. (only one script now as it's already executed and cleared out the initial entries). This causes my application to open as if it were a second boot, only when next is clicked on the add hardware wizard. If I click cancel, and reboot, then it also works as expected. I don't care as much about other solutions, because I could design a system that doesn't fully rely on Microsoft's registry. I simply can't find any information as to WHY this is happening. I believe this is some type of Microsoft issue that's presenting itself as a result of an overstretched image that's expected to support too many legacy platforms, but any help that can be provided would be appreciated. Thanks,

  • Android: how to detect a private number programmatically

    - by Bao Le
    I use BroadcastReceiver to intercept incoming call on Android phone as below tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); Bundle bundle = intent.getExtras(); String number = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER); In the "private number" case, I tested on two devices, it shows the number as -1 on HTC Wildfire and -2 on Galaxy S. I checked the android.telephony.PhoneNumberUtils but it could't help me. Is there a function or a generic way to detect a private number on Android phone? Thanks

  • iPhone Application Deploy without using iTunes

    - by Paulo Correia
    I want to build an application for the iPhone to be used inside a customer enterprise (very small, only 5 to 10 devices). But since they will be paying the application development, I don't want to distribute that application to the world inside the App Store in iTunes. How can I distribute this app to my customer? Should I get the Enterprise level subscription from the Apple Developer Program? Since I work as a freelancer, I think I can't subscribe to that program.

  • Statistics of IMAP vs POP vs Exchange ?

    - by Antares
    Hello, I'm desperately looking for some statistics about usage of POP versus IMAP versus Exchange-MAPI, especially in professional context. I know IMAP is used for accessing mails from mobile devices with limited bandwidth, whereas POP is the good old standard, and Exchange is more business-oriented. Does someone know the approximate percentage of usage of each protocol ? Thanks !

  • Javascript Mp3 Player, NONE FLASH

    - by Yo Momma
    I currently have a simple flash Mp3 player on my site which works lovely. The issue is, most cell phones do not support flash and a large portion of my visitors come through via a mobile device. The alternative to this is to replace the flash player with a javascript player. I found a JQuery one but it only works on HTML5 compatible browsers. Does anyone know of a good alternative that would work on mobile devices as well as most desktop web browsers?

  • Windows Mobile: "My network card connects to" registry settings

    - by Martin Robins
    Can anybody please tell me the registry setting(s) that are affected in Windows Mobile 6.1 when a user selects Start - Settings - Connections - Wi-Fi and then changes the value of the "My network card connects to" drop down list on the "Network Adapters" tab? I have a device that seems to default this to "The Internet" when in fact the Wi-Fi connects to the corporate network and I would like to be able to change this programatically rather than expecting 250+ users to have to do it manually every time they reboot their devices. Thanks.

    I'm building a web site that needs to stream video and be friendly for handheld devices (especially the iPhone). Some handhelds don't support Flash so I'm avoiding the use of a Flash player. How does Youtube stream its videos so that they play on both desktops and iPhones? I'm looking for a player, or multiple players, which can be somehow activated based on the user's device. Your help and guidance are much appreciated. Thanks.

  • optimizing any OS for maximum informix client/server performance

    - by Frank Developer
    Is there any Informix documentation for optimizing any operating system where an ifx engine is running? For example, in Linux, strip-down to a bare minimum all unnecessary binaries, daemons, utilities, tune kernel parameters, optimize raw and cooked devices (hdparm), place swap space on beginning tracks of a disk, etc. Someday, maybe, Informix can create its own proprietary and dedicated PICK-like O/S to provide the most optimized environment for a standalone ifx server? The general idea is for the OS where ifx sits on have the smallest footprint and lowest overhead impact.
