• Show extra info for Preference screens when CheckboxPreference summary field is not enough long?

  - by Pentium10

  I have situation when you can enabled/disable modules for my Android application. For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines. Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window. I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, where ever you click on the line the checkbox is toggled. So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox. How would you do it? I am open to other ideas too, if they do work.

• What are the pro and cons of having localization files vs hard coded variables in source code?

  - by corgrath

  Definitions: Files: Having the localization phrases stored in a physical file that gets read at application start-up and the phrases are stored in the memory to be accessed via util-methods. The phrases are stored in key-value format. One file per language. Variables: The localization texts are stored as hard code variables in the application's source code. The variables are complex data types and depending on the current language, the appropriate phrase is returned. Background: The application is a Java Servlet and the developers use Eclipse as their primary IDE. Some brief pro and cons: Since Eclipse is use, tracking and finding unused localizations are easier when they are saved as variables, compared to having them in a file. However the application's source code becomes bigger and bloated. What are the pro and cons of having localization text in files versus hard coded varibles in source code? What do you do and why?

• Android - LinearLayout Horizontal with wrapping children

  - by kape123

  Is there a property to set for Android's LinearLayout that will enable it to properly wrap child controls? Meaning - I have changeable number of children and would like to lay out them horizontally like: Example: Control1, Control2, Control3, ... I do that by setting: ll.setOrientation(LinearLayout.HORIZONTAL); foreach (Child c in children) ll.addView(c); However, if I have large number of children, last one gets cuts off, instead of going to next line. Any idea how this can be fixed?

• How can I stop a default event when using a named function in addEvent?

  - by Rupert

  Normally, if I wish to stop a default event in mootools I can do this: $('form').addEvent('submit', function(e) { e.stop(); //Do stuff here } However, I don't like using an anonymous function in events because I often want to reuse the code. Lets say I have a validate function. I could do this: $('form').addEvent('submit', validate); which works fine until I want to stop the default event. validate obviously doesn't know what e is so I can't just do e.stop(). Also I've tried passing the event as a variable to validate but whenever I use a named function with parameters, the function gets called automatically on domready, rather than on the event firing. Even worse, an error is thrown when the event is fired: What am I doing wrong?

• How can invoke a shell to make a new environment to run a make inside another make?

  - by WilliamKF

  I would like in my GNUmakefile to have a target rule that invokes a new shell and then with the clean slate of the new shell invokes a new make. What is the syntax to do this? I tried this but it didn't work: .PHONY: setup setup: shell cd myDir; make; cd .. It gets infinite repeat of the following error: make[1]: Entering directory `/disk4/home/user/parent' shell cd myDir; make; cd .. /bin/sh: shell: command not found make[1]: Entering directory `/disk4/home/user/parent' shell cd myDir; make; cd .. /bin/sh: shell: command not found [...]

• Kohana controller shows blank page if missing URI segment/argument

  - by Petruza

  When accessing http://www.nowplayingnashville.com/event2/detail/440698386/Whatever the controller shows normally. But when omitting the last parameter (event's title, which can be any string), http://www.nowplayingnashville.com/event2/detail/440698386/ It shows blank. I added a default value and tried to hardcode the title on the first line of the controller, but it doesn't work anyway. It looks like a view issue, because I can add an echo at the end of the controller and it gets printed, so the controller is executing to the end, but the views aren't displayed. This problem is present on the live site, but I checked out the code on my local machine and it works perfectly without a title. That's strange. Could it be a Kohana or Apache configuration issue?

• Queue remote calls to a Python Twisted perspective broker?

  - by agartland

  The strength of Twisted (for python) is its asynchronous framework (I think). I've written an image processing server that takes requests via Perspective Broker. It works great as long as I feed it less than a couple hundred images at a time. However, sometimes it gets spiked with hundreds of images at virtually the same time. Because it tries to process them all concurrently the server crashes. As a solution I'd like to queue up the remote_calls on the server so that it only processes ~100 images at a time. It seems like this might be something that Twisted already does, but I can't seem to find it. Any ideas on how to start implementing this? A point in the right direction? Thanks!

• In MVVM are DataTemplates considered Views as UserControls are Views?

  - by Edward Tanguay

  In MVVM, every View has a ViewModel. A View I understand to be a Window, Page or UserControl to which you can attach a ViewModel from which the view gets its data. But a DataTemplate can also render a ViewModel's data. So I understand a DataTemplate to be another "View", but there seem to be differences, e.g. Windows, Pages, and UserControls can define their own .dlls, one type is bound with DataContect the other through attaching a template so that Windows, Pages, UserControls can can be attached to ViewModels dynamically by a ServiceLocator/Container, etc. How else are DataTemplates different than Windows/Pages/UserControls when it comes to rendering a ViewModel's data on the UI? And are there other types of "Views" other than these four?

• Custom "Very Long Int" Division Issue

  - by befall

  Hey everyone, So, for a very silly project in C++, we are making our own long integer class, called VLI (Very Long Int). The way it works (they backboned it, blame them for stupidity) is this: User inputs up to 50 digits, which are input as string. String is stored in pre-made Sequence class, which stores the string in an array, in reverse order. That means, when "1234" is input, it gets stored as [4|3|2|1]. So, my question is this: How can I go about doing division using only these arrays of chars? If the input answer is over 32 digits, I can't use ints to check for stuff, and they basically saying using long ints here is cheating. Any input is welcome, and I can give more clarification if need be, thanks everyone.

• Setting date from selectInputDate to object

  - by DD

  I have a date controller which does various things. Once a calendar date is set, I want to pass the value from the date controller to another bean. The problem I have is that the setPropertyActionListener gets called before the user clicks on a date. Is there a way to get the date from the selectInputDate after selection and pass to a bean? This is what I tried: <ice:selectInputDate popupDateFormat="dd-MMM-yyyy" renderAsPopup="true" value="#{dateRangeDateContoller.end}" > <f:setPropertyActionListener target="#{searchParameters.endDate}" value="#{dateRangeDateContoller.end}" /> </ice:selectInputDate>

• Mysql query taking too much time

  - by aditya

  I have problem related to mysql database. i am linux webserver admin and i am facing a problem with a mysql query. The database is very small. I tried to track in logs and found that a query is taking minimum 5 sec to respond . The first page of site is coming from the database. Client are using cms. when the server gets some number of hits database server starts to give response very slowly and wait time increases from 5 sec to several seconds. I checked slow query logs { Query_time: 11.480138 Lock_time: 0.003837 Rows_sent: 921 Rows_examined: 3333 SET timestamp=1346656767; SELECT `Tender`.`id`, `Tender`.`department_id`, `Tender`.`title_english`, `Tender`.`content_english`, `Tender`.`title_hindi`, `Tender`.`content_hindi`, `Tender`.`file_name`, `Tender`.`start_publish`, `Tender`.`end_publish`, `Tender`.`publish`, `Tender`.`status`, `Tender`.`createdBy`, `Tender`.`created`, `Tender`.`modifyBy`, `Tender`.`modified` FROM `mcms_tenders` AS `Tender` WHERE `Tender`.`department_id` IN ( 31, 33, 32, 30 ); } Every line in the log is same only there is diff in Query time. Is there any way tweak the performance?

• How to build the ViewModel in MVVM not to violate the Single Responsibility Principle?

  - by Przemek

  Robert Martin says: "There should never be more than one reason for a class to change". Let's consider the ViewModel class which is bound to a View. It is possible (or even probable) that the ViewModel consists of properties that are not really related to each other. For small views the ViewModel may be quite coherent, but while the application gets more complex the ViewModel will expose data that will be subject to change for different and unrelated reasons. Should we worry about the SRP principle in the case of ViewModel class or not?

• SQL Server Express 2008 Stored Procedure execution time spikes periodically

  - by user156241

  I have a big stored procedure on a SQL Server 2008 Express SP2 database that gets run about every 200 ms. Normal execution time is about 50ms. What I am seeing is large inconsistencies in this run time. It will execute for while, say 50-100 times at 40-60ms which is expected, then seemingly at random the same stored procedure will take way longer, say 900ms or 1.5 seconds to run. Sometimes more than one call of the same procedure in a row will take longer too. It appears that something is causing sql server to slow down dramatically every minute or so, but I can't figure out what. There is no timing pattern between the occurences. I have the same setup on two different computers, one of which is a clean XP Pro load with no virus checking and nothing installed except SQL server. Also, The recovery options for all the databases are set to "Simple".

• How to make an scrollable UITextField Inside UItableViewCell?

  - by user333624

  Hello everyone. I created a bunch of editable UITableViewCell by embedding an UITextField inside, but I have seen some apps that allows you to scroll the UItableview by scrolling inside an inactive editable cell. How can I do that? And how can I also dismiss the keyboard when tapping somewhere else? I know about the method: - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; if (touch.tapCount == 1) { [self resignFirstResponder]; } else { }} I put it inside my custom table view controller but the method doesn't seem to be called upon a tap, and I don't know if even if it gets called will dismiss the keyboard. Any help will be appreciated.

• Objective-C: when does an assigned object get deallocated

  - by Stefan Klumpp

  If I have a instance method and within this method I do something like this: NSString *peopleString = [peopleList componentsJoinedByString: @", "]; ... UILabel *likeLabel = [[UILabel alloc] initWithFrame:CGRectMake(16.0+6.0f, 4.0f, 252.0f, 12.0f)]; [likeLabel setText:peopleString]; [likeLabel setFont:[UIFont fontWithName:@"Arial" size:12]]; [likeRow addSubview:likeLabel]; [likeLabel release]; The componentsJoinedByString doesn't contain a new, copy or alloc, thus I don't have to release it. What I'm wondering though is, when my peopleString gets deallocated. Might it happen to early? Meaning, before I can set the text in my label. Should I better use a [[NSString alloc] initWithString:[peopleList componentsJoinedByString: @", "]]; and release it at the end of this method?

• Scriptaculous Slider stops working in iFrame

  - by KcYxA

  Hi there, I am stumped! I have a form for leaving reviews that uses a slider from the Scriptaculous library. The form is retrieved through Ajax once a user clicks on a link to leave a review and all works fine. In order to enable ajax-looking file uploading, I'm using an iFrame to submit the review. My problem occurs when the form is returned due to user input errors. The slider stops working! No Javascript errors. The Control.Slider gets initialized, yet it doesn't work. Any ideas on why this could be happening? Thanks!

• How to rotate a UIImageView?

  - by jkally

  It's quite frustrating not to be able to do such a simple task: I have an "app" with a single viewcontroller, and in it a single UIImageView, that's initialized to a specific image at potrtait mode. Now when the iPhone gets roteated to landscape mode and the shouldAutorotateToInterfaceOrientation event fires, at which I return YES, my resulting UIImageView looks totally screwed up: either the image is stretched so to fill landscape mode frame (which looks ridiculuous of course) or the top and bottom of the image are cropped. How can I have my UIImageview and the contained image handle the device rotation gracefully, and display normal looking image at landscape mode as well?

• How to preload local javascript everytime a new tab or page is opened?

  - by Klerk

  I would like to autoload a local javascript file, everytime a new page/tab is opened in a browser. I tried the bookmarklet approach, but it gets tiresome as the button needs to be pressed everytime a new page/tab is opened. Chrome extensions also seem to work along the same lines (where you have to press an icon to run the js). Googling for javascript and preload seems to return everything except what I am looking for. Is there a browser indepent way of autoloading (no user action required) a local js file? If not, any browser specific info to do this would be appreciated (even if they mean reducing security by turning off required options). Thanks!

• Instantiate ItemsPanelTemplate

  - by Stephan

  I'm trying to create a ItemsControl that has a separator between items, for example a control to create a navigation bread crumb. I want the control to be completely generic. My original method was to create extend ItemsControl, add a SeparatorTemplate property, and then have the class add separators to the ItemsHost of the ItemsControl. The problem with this approach is that if you add extra items to the container panel, the ItemGenerator gets confused and the items are out of order and don't get removed correctly. So my second plan was to create a completely new control that would emulate an ItemsControl, but the problem I'm running into is that I can't find a way to instantiate an ItemsPanelTemplate. I would like to provide an ItemsPanel property just like ItemsControl, but I can't then create a panel from that template. Can anyone think of a way to either instantiate an ItemsPanelTemplate or way to add controls to an ItemsControl's panel without breaking the ItemGenerator?

• How does one implement a truly asynchronous java thread

  - by Ritesh M Nayak

  I have a function that needs to perfom two operations, one which finishes fast and one which takes a long time to run. I want to be able to delegate the long running operation to a thread and I dont care when the thread finishes, but the threads needs to complete. I implemented this as shown below , but, my secondoperation never gets done as the function exits after the start() call. How I can ensure that the function returns but the second operation thread finishes its execution as well and is not dependent on the parent thread ? public void someFunction(String data) { smallOperation() Blah a = new Blah(); Thread th = new Thread(a); th.Start(); } class SecondOperation implements Runnable { public void run(){ // doSomething long running } }

• Android RelativeLayout spacing

  - by fordays

  Hi, I'm just putting the finishing touches to my Android app. Unfortunately, I dug straight into development without reading the documentation and built my layout with AbsoluteLayout and it turned out to look terrible when I loaded the app on my phone. Now I'm redoing the UI in a RelativeLayout and I want to put empty canvas space in between my ViewGroups in the y-direction. I am currently achieving this by putting random TextView sentences that are of the same color as my View's background in order to make psuedo-empty space. Is there a better way to do this, because right now when I define a specific ViewGroup to be placed below another View, it gets stuck right below the top View. As I was writing this, it dawned upon me that using padding might be the answer.... Any other suggestions?

• IntelliJ: Including jars in a jar artifact

  - by skiaddict1

  Developing on the Mac with IntelliJ 9.0.2. I have a program which depends on two library jars. I have figured out how to get IntelliJ to make me a jar of my source (with the Artifact tab), and even to include the two jars in it. However, if I get a listing of the jar file it produces, it looks like this: com/acme/MyClass1.class com/acme/MyClass2.class ... mylib1.jar myLib2.jar And, no surprises, if I double-click the jar file, it gets a NoClassDefFoundError the first time it tries to access a class in one or other library jar. How do I get IntelliJ to include the two library jars such that the classes are visible?

• CSS and control name mangling in content pages

  - by flashnik

  I have a simple website with a master-page. To set properties to elements on a content page (such as Textbox) I use CSS. In designer it works well but when I launch a site a style isn't apllied to controls. The reason is simple. To say, I have a TextBox with id="TextBox1" in content page, it is placed in ContentPlaceHolder1. In CSS file I set properties for object with id #TextBox1. When I launch a site due to master page name mangling it gets an id like ctl00_ContentPlaceHolder1_TextBox1 which is not defined in CSS file included in masterpage. What is a correct solution of this problem? Hardcoding mangled name doesn't seem to be good.
