  • Preventing sleep in Titanium for iPhone

    - by Morten J
    I'm trying to read the accelerometer for a longer period of time (between one and two hours). However, when the iPhone goes to sleep and locks, the reading of the accelerometer readout is paused. My setInterval timer seems to be running fine though. I can also play sounds. I see two solutions a) Find a way to read the accelerometer while locked b) Find a way to prevent the lock I'm using Titanium with JavaScript.

  • Matlab Simulink version control with multiple developers

    - by Jon Mills
    We're using Matlab Simulink for model development (and Real-Time Workshop autocoding) within a team of several developers. We currently use Visual Source Safe (yes, I know its terrible) for version control, using locks to prevent conflicting changes. We'd like to migrate our programme to a different version control system (svn, hg or git), but we're concerned about performing merges and diffs on Simulink .mdl files. Does anybody have useful experience in performing merges on Simulink files?

  • How to refresh an Android RelativeLayout when orientation changes without restarting the Activity?

    - by johnrock
    I have an Android Activity with a RelativeLayout and I have implemented the following method to prevent the activity from being recreated on change of Orientation: @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); } I am obviously not doing anything in this method, but it worked perfect when using a LinearLayout. Now however, using RelativeLayout, my layout is all messed up when changing to landscape orientation. What is the most efficient way to have the screen redraw correctly without having the activity restarted again with a call to onCreate?

  • Private constructor and public parameter constructor -C#

    - by Amutha
    I heard that private constructor prevent object creation from outside world. When i have a code public class Product { public string Name { get;set;} public double Price {get;set;} Product() { } public Product(string _name,double _price) { } } here still i can declare public constructor(parameter),won't it spoil the purpose of private constructor? When do we need both private and public constructor(parameter) in code? I need detailed explanation please.

  • My images are blurry! Why isn't WPF's SnapsToDevicePixels working?

    - by Zack Peterson
    I'm using some Images in my WPF applcation. XAML: <Image Name="ImageOrderedList" Source="images/OrderedList.png" ToolTip="Ordered List" Margin="0,0,5,5" Width="20" Height="20" SnapsToDevicePixels="True" MouseUp="Image_MouseUp" MouseEnter="Image_MouseEnter" MouseLeave="Image_MouseLeave" /> But, they appear fuzzy: Here's a zoomed-in, side-by-side comparison. An original is on the left: Why doesn't that SnapsToDevicePixels="True" line prevent this problem?

  • MySql, InnoDB & Null Values

    - by pws5068
    Formerly I was using MyISAM storage engine for MySql and I had defined the combination of three fields to be unique. Now I have switched to InnoDB, which I assume caused this problem, and now NULL != NULL. So for the following table: ID (Auto) | Field_A | Field_B | Field_C I can insert (Field_A,Field_B,Field_C) Values(1,2,NULL) (1,2,NULL) (1,2,NULL) infinitely many times. How can I prevent this behavior?

  • Casting of interfaces

    - by Srinivas Reddy Thatiparthy
    interfaces provide a useful abstraction capability. One can have a class Foo implement some interfaces, say A, B, and C. Some client code may get a reference of type A, others one of type B, etc. each actually the same Foo object but the interface exposing only a narrow subset of the functionality. Of course, evil client code can try to cast the A reference to Foo, then access the other functionality.How to prevent this?

  • Preventing a WPF Expander from expanding when header is clicked

    - by emddudley
    How can I prevent a WPF Expander from expanding when its header is clicked? I would like my Expander to expand or collapse only when the expand button itself is clicked. I imagine the answer has something to do with canceling a bubbled event. If possible I would like to implement the solution in XAML while avoiding retemplating the entire Expander.

  • The Main Purpose of Events in C#

    - by Tarik
    I've been examining one of my c# books and I just saw a sentence about Events in C#:  The main purpose of events is to prevent subscribers from interfering with each other. Whatever it means, yeah actually events are working pretty much like delegates. I've been wondering why I should use events instead of delegates. So is there any one who can explain the bold part? Thanks in advance.

  • Flex 3.5 Accordion and TabNavigator Index Change Bug

    - by majgis
    I'm using Flex 3.5 with Adobe Flex Builder 3. I have found that if you very rapidly click between multiple headers of an accordion component or the tabs of TabNavigator, these components will begin to exhibit odd, unexpected behavior. Has anyone else experienced this behavior and do you know of a patch that can prevent the user from getting in a situation where the tab/header they click on is not the one made visible?

  • How do I rollback capistrano tasks upon failure?

    - by dchua
    In my Capistrano deploy.rb, I have a couple of daemons like delayed_jobs and fetcher, starting and stopping depending on where they are in the deployment process. This method would create problems if a deployment fails, because the daemons wouldn't be managed properly (ie. two processes spawned instead of one, or processes were shutdown without restarting itself until the next deployment). Is there anyway to prevent this from happening like a rollback code? How is deployment of daemons normally done over capistrano?

  • Why Is ToString() Rounding My Double Value?

    - by user163757
    How do I prevent my double value from being rounded when converting to a string? I have tried both Convert.ToString and ToString() with the same result. For example my double may look something like 77.987654321, and the two strings conversions convert to to 77.98765. I need to keep the precision of the value as is.

  • Restricting empty elements in xsd

    - by Chris Welsh
    Is there a way to prevent empty elements of the form <myElement/> being used in your xml? In other words, can you specify in your xsd that <myElement/> is invalid? Using nillable="false" doesn't work, nor does minOccurs="1" - both of those allow <myElement/>.
