  • Android ImageButton with a selected state?

    - by Joren
    If I was using an ImageButton with a selector for its background, is there a state I can change which will make it change its appearance? Right now I can get it to change images when pressed, but there seems to be no "highlighted" or "selected" or similar state which lets me toggle it's appearance at will. Here's my XML, it only changes appearance when pressed. <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/map_toolbar_details_selected" /> <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/map_toolbar_details_selected" /> <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/map_toolbar_details_selected" /> <item android:drawable="@drawable/map_toolbar_details" />

  • Elasticsearch Shard stuck in INITIALIZING state

    - by Peeyush
    I stopped one of my elastic search node & as a normal behavior elastic search started relocating my shard on that node to another node. But even after 15 hours it is still stuck in INITIALIZING state. Also that shard is fluctuating between two nodes,for some time it stays on one node then automatically shift to another node & keep on doing that after every few hours. Main issue is it is still in INITIALIZING state after so many hours. I am using version 1.2.1. This shard which is stuck, it is a replica. I am getting this error in logs: [ERROR][index.engine.internal ] [mynode] [myindex][3] failed to acquire searcher, source delete_by_query java.lang.NullPointerException [WARN ][index.engine.internal ] [mynode] [myindex][3] failed engine [deleteByQuery/shard failed on replica] [WARN ][cluster.action.shard ] [mynode] [myindex][3] sending failed shard for [myindex][3], node[Sp3URfNVQlq2i4i3EjCakw], [R], s[INITIALIZING], indexUUID [kTikCHshQMKEQ_jAuWWWnw], reason [engine failure, message [deleteByQuery/shard failed on replica][EngineException[[myindex][3] failed to acquire searcher, source delete_by_query]; nested: NullPointerException; ]]

  • ASP.NET Session State Error only on default document

    - by schmidty
    I have a site where when accessing via site.com/default.aspx everything is fine, however when accessing via site.com/ I get a session error as follows: "Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration." I have confirmed that default.aspx is the highest priority default document and that it is the page being loaded. However why is this session error only occurring when accessing via the default document? The server is 2008 R2 and IIS 7.5.

  • Locking on an object...

    - by Mystere Man
    I often see code like that which is shown here, ie where an object is allocated and then used as a "lock object". It seems to me that you could use any object for this, including the event itself as the lock object. Why allocate a new object that does nothing? My understanding is that calling lock() on an object doesn't actually alter the object itself, nor does it actually lock it from being used, it's simply used as a placeholder for multiple lock statements to anchor on. So my question is, is this really a good thing to do?

  • saving iPhone program state with a deep UINavigationController

    - by jr
    Can someone a good way to save the program state (UINavigationController stack, etc) of an iPhone application. My application obtains a bunch of information from the network and I want to return the person back to the last screen they were on, even if it was 3 or 4 screens deep. I assume that I will need to reload the data from the network along the way as I recreate the UINavigation controllers. I don't necessarily have a problem with this. I'm thinking about maybe having my UINavigationController objects implement some type of protocol which allow me to save/set their state? I'm looking to hear from others who may have needed to implement a similar scenario and how they accomplished it. My application has a UITabbarController at the root and UINavigationController items for each tab bar item. thanks!

  • Bug when adding a sprite to 1 <s:State>

    - by lostincode
    I'm working within a skin for a button that has some <s:State> normal over In the tag, I'm drawing a circle private var theshape:Sprite; private function drawShape():void { theshape = new Sprite(); theshape.graphics.beginFill(0x666666); theshape.graphics.drawCircle(3,5,10); theshape.graphics.endFill(); //i then add it to a Spite Visual Element that's defined in mxml canv.addChild(theshape); } This works fine, until I try to control under which states that canv SpriteVisualElement appears. If I just add an includeIn like this <s:SpriteVisualElement id="canv" includeIn="over" /> I get a run-time error TypeError: Error #1009: Cannot access a property or method of a null object reference. Any ideas what the problem is, or a different way I can accomplish the same thing. What I need is to simply include the circle in the button when it's in the hover state.

  • Sessionstate not being saved between pages

    - by Grant
    Hi, i am having problems with an asp.net c# site whereby i am setting a session state object to true and then redirecting to another page that needs to check the value of the session state object and it is null. Sometimes it is set correctly and other times is is simply null. When i debug on my local machine it works perfectly every time. Only when i upload to my web server does this temperamental behaviour happen. As it is based around the security of the site it is obviously important that the session data be valid and accurate every time. Is session state data unreliable? AFAIK its set to inproc, cookieless, 30 min timeout, vanilla installation of IIS. Does anyone have any suggestions? Perhaps i need to thread.sleep inbetween the storing of the session data and the reading? NB: the time between the write and the read is about 70ms.. ample time for the data to be written to RAM.....

  • How to handle model state errors in ajax-invoked controller action that returns a PartialView

    - by Robert Koritnik
    I have a POST controller action that returns a partial view. Everything seems really easy. but. I load it using $.ajax(), setting type as html. But when my model validation fails I thought I should just throw an error with model state errors. But my reply always returns 500 Server error. How can I report back model state errors without returning Json with whatever result. I would still like to return partial view that I can directly append to some HTML element. Edit I would also like to avoid returning error partial view. This would look like a success on the client. Having the client parse the result to see whether it's an actual success is prone to errors. Designers may change the partial view output and this alone would break the functionality. So I want to throw an exception, but with the correct error message returned to the ajax client.

  • Modelling multiple simultaneous states

    - by James P.
    How can you go about modelling an object that can have multiple simultaneous states? For example, you could have a person that's waiting for a bus. That's one state. But they could also be reading a newspaper while waiting for the bus. Furthermore, they could be thinking about something while reading the newspaper. They could also be sniffing their nose because they have a cold. That's a four states in all taking place at the same time. Obviously using booleans would be tedious and unflexible. Also, a conventional state pattern would mean that states are exclusive and can't be simultaneous in nature. The only thing I can think of is a State pattern combined with a Composite. Would this do or is there a way of taking things further?

  • Asp.net error object not set to a reference

    - by Frank
    Hi all, Because I rush in development (a lot of whip cracking here) and declare my objects at the top of the function and instantiate inside my try-catch block, I get a lot of the good old "object not set to an instance of an object" errors while doing TDD, and later if I do miss a branch that object was used in (doing VB now, would prefer C#) or just in every day coding, object not set to an instance of an object is a bit vague. Sure the stack trace sends me to the line the error occured at, but it would be nice if I could modify my logging to either name the object or its type because sometimes I have multiple objects on the same line. It's not the end of the world, but in the end it would save me a few minutes each day. Any ideas on how I can pass the info on which object wasn't set? Thanks

  • What comes first in Ruby's object model?

    - by Timothy
    I've been reading Metaprogramming Ruby and the object model like the chicken or egg dilemma. In Ruby 1.8, the Object class is an instance of Class. Module's superclass is Object and is an instance of Class. Class' superclass is Module, and it is an instance of Class (self-referential). Say class SomeClass; end is defined somewhere; SomeClass is an instance of Class, however its superclass is Object. Why does an instance of Class have Object as the superclass instead of nil? Also, if Object is to exist, then Class has to exist, but then Module has to exist, but for Module to exist Object has to exist. How are these classes created?

  • Powershell Select-Object from array not working

    - by Andrew
    I am trying to seperate values in an array so i can pass them to another function. Am using the select-Object function within a for loop to go through each line and separate the timestamp and value fields. However, it doesn't matter what i do the below code only displays the first select-object variable for each line. The second select-object command doesn't seem to work as my output is a blank line for each of the 6 rows. Any ideas on how to get both values $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data) $csv2 = convertFrom-CSV $csvdata $newarray = $csv2 | Where-Object {$_.utilization -ne "0.0000000000e+00" -and $_.utilization -ne "nan" } for ( $n = 0; $n -lt $newarray.Length; $n++) { $nTime = $newarray[$n] $nUtil = $newarray[$n] $util = $nUtil | select-object Utilization $util $tstamp = $nTime | select-object timestamp $tstamp }

  • Asp.Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea? Update : The error occur in a page extending System.Web.UI.Page in the method InitializeCulture() which is an override.

  • Best way to map/join two autogenerated enums

    - by tomlip
    What is the best C++ (not C++11) way of joining two enums from autogenerated class similar to one presented below: namespace A { namespace B { ... class CarInfo { enum State { // basically same enums defined in different classes Running, Stopped, Broken } } class BikeInfo { enum State { // basically same enums defined in different classes Running, Stopped, Broken } } } } What is needed is unified enum State for both classes that is seen to outside world alongside with safe type conversion. The best and probably most straightforward way I came up with is to create external enum: enum State { Running, Stopped, Broken } together with conversion functions State stateEnumConv(A::B::CarInfo::State aState); State stateEnumConv(A::B::BikeInfo::State aState); A::B::CarInfo::State stateEnumConv(State aState); A::B::BikeInfo::State stateEnumConv(State aState); Direction into right approach is needed. Gosh coming from C I hate those long namespaces everywhere an I wish it could be only A::B level like in presented example. Four conversion functions seem redundant note that CarInfo::State and BikeInfo::State has same enum "members".

  • Passing an object as a parameter to a windows service

    - by user220723
    Is there some way to pass an object to a windows service? I know the method myServiceController.Star(string[] arg) but i need to pass a more complex object than a string array. Actually, i don't need the object to be passed as a parameter, what i really needs is that the service can use an object created in a windows forms application. I've tried using System.Web.Script.Serialization.JavaScriptSerializer.Serialize method to convert the object into a Json but i couldn't because the object contains a circular reference. I also tried using pointers, but i couldn't becouse it is a managed type object. Any idea what can i do?

  • How did My Object Get into ASP.NET Page State?

    - by Paul Knopf
    I know what this error is, how to fix it, etc. My question is that I don't know why my current page I am developing is throwing this error when I am not using the foo class directly in any way, nor am I setting anything to the viewstate. I am using postbacks alot, but like I said, I am not storing anything in the viewstate etc one integer. I am using nhibernate if that is relevant.
