• Android Round Button and Spinner inside Activity Group

  - by vaishali

  I have a Spinner and 2 buttons in an Activity Group. I want to apply rounded corner to the buttons. I have created shape xml resource file for round button in Android. I have assigned this resource file as background to the button while creating the button in Layout. But the change is not reflected after executing the application. I have set the ContentView for that screen as : setContentView(LayoutInflater.from(getParent()).inflate(R.layout.textmessage,null)); This has to be done to make spinner work in an Activity Group. How can I make the Button as round corner in an Activity Group having Spinner? Any help would be appreciated. Thanks in Advance.

• Software to cd (change directories) into .jar/.ear files?

  - by Segphault

  Is there any software/script that will allow me to cd (change directories) into .jar/.ear/.zip files and edit the contents of the files it contains? I'm working on a large EJB project (yuck), and I frequently find myself in situations like the following: something.ear/ |-- something.jar/ | `-- fileINeedToEdit.xml I work primarily via the command line (Mac/Linux), so I find myself decompressing the files with jar -xvf, editing the file I need to edit, and then recompressing with jar -cvf. Obviously, this becomes a major headache after the first few times. I'd like to be able to treat the compressed files as directories, and simply cd (or some alternate command) to the file I want to edit. Does anyone know how I can accomplish this?

• RSS feed per tag

  - by niaher

  Hi. Suppose stackoverflow.com wanted to have an RSS feed per each tag. They would probably have requests like stackoverflow.com/rss?tag=aspnet to return appropriate RSS feeds. This is the easy part. Now when the user requested stackoverflow.com/rss?tag=aspnet he would see some XML. Instead it would be better to show a page where user can choose which RSS reader he wants to subscribe with (just like feedburner.com). My question is: is there any ready-made code (html+javascript) that I can copy-paste to create such a subscription page? Basically I want to copy feedburner.com's subscription page onto my own site. PS - I would be happy using feedburner.com, but it would require me to create a feed for each tag manually, which is impractical.

• NoMethodError using Memcached Sinatra-style

  - by sevennineteen

  I've just installed Memcached on my Mac and updated my Sinatra app configuration as described in Heroku's documentation, but I'm getting a NoMethodError when trying to use the hash-based syntax they specify: >> CACHE['color'] = 'blue' >> CACHE['color'] Using explicit get and set methods as below seems to work fine. >> CACHE.set('color', 'blue') >> CACHE.get('color') If necessary I can use the latter syntax, but the former seems more elegant. I haven't tested this on Heroku's environment since I'd like whatever implementation I use to work on my local environment as well. Thanks!

• TimePicker Android and a Database

  - by user1820528

  I have a database with a table which contains a start time and an end time. The user has to select both through the Android app, and then I have to retrieve the two times into my database. For now, I have 2 TimePicker in my xml file, and I have 2 TimePicker in my java file TimePicker start_time = (TimePicker) findViewById(R.id.timePickerStart); Can someone help me know how I should retrieve the times, and use them in java (add a listener, etc.). And also, should I use TimeStamp or Date in the database ? My purpose is to send a notification (Toast?) to the user at those times. So should I retrieve the hour and the minute separately ? I'm sorry for asking so many questions, but I'm really lost here :( Thank you!

• Android preferencesActivity setDefaultValue() not working?

  - by Nick

  I'm extending PreferenceActivity for my settings screen. In this preference activity i have a couple of preferences one of which is custom made. The problem is as follows: in this custom preference (which extends from ListPreference) i want to be able to set the default value, so i override the setDefaultValue() method. In this method i do some parsing so it'll take the correct value. When i'm trying to read this value with the getValue() function it just returns null. So i figured, what happens when i just put some hardcoded value in there (you know, maybe i did something wrong, wouldn't be the first time). Well, i still get null back. Any ideas what i'm doing wrong? Edit: Setting the defaultValue in the xml file isn't really an option because the values aren't known until i retrieve them. I made a workaround: When app is started for the first time: get data Set the values in the preference. This way i set the default preference when i'm collection the data

• R.java doesn't exist...but it does! Problem started after installing ADT 10.0.0

  - by TenFour04

  I get this error when I try to clean a project: ERROR: Unable to open class file ....R.java: No such file or directory So I can't build my projects any more. But R.java is there in the gen folder and looks fine when I open it. This happens to every one of my projects. I tried completely deleting the Eclipse folder and reinstalling it (Helios on Windows) and Android ADT. No luck. I have also tried moving my workspace to a different drive. No luck. I made sure all folders in my workspace are not read only. This worked the first time, but immediately the error came back when I cleaned my project. This all started right after installing ADT 10.0. I am wondering if it somehow is building R.java as a read-only file. EDIT: Is deleting the eclipse directory sufficient to reset all of its configuration?

• vb express / visual studio - is it possible to run / debug one form only in a multi form application

  - by Luay

  hi, I have a vb application consisting of several winForms and code files. Is it possible to run / debug only one form without having to run the whole application? To be more specific, one of the forms in my application is the settings form where the user sets his/her desired options. These options are read/written to an xml file. Is it possible to debug just this one form (and not the whole program) to see if the reading/writing went well, if everything displayed correctly... ? If I am thinking the wrong way about this, could you point me in the right direction? By the way, I am using visual basic express / visual studio.

• How do I change the number of thumbnails seen in the Android sample Home application?

  - by Todd

  I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options. When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown. I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered. I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point. How do I show all four of my wallpaper options?

• Caching in Ruby Gem, possibly not using Rails

  - by corprew

  I am rewriting an existing Ruby Gem to include caching. This is for a gem that is relatively commonly used, and accesses a large amount of static data on a web service. Currently, I have a small number of gem users doing a large number of accesses to the service that under normal conditions would be swamping / downing the service, and we're going to put the gem up on github for general consumption. Right now, users can choose between using the rails cache mechanism, a simple disk cache, or no cache. What is best practice for letting people choose what cache to use like this (being able to use this outside of rails is a priority so i can't just bail to the underlying caching mechanism)? I'm looking for suggestions/examples for configuration and interface, especially. Thanks for your suggestions

• How to deal with multiple screensizes + dynamic controls in Android?

  - by chobo2

  Hi I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions. I read the tutorial on the android site and still unsure how to do it. First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files. So I am not sure how to android to re size dynamic controls based on the screen size. I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do. So is there some other way to do it that is considered good practice?

• Android layout issue - table/grid/linear

  - by phpmysqlguy

  I am trying to wrap my head around some basic layout issues in android. Here is what I want as my final goal: As you can see, various fields set up like that. The fields get filled in based on XML data. There could be 1 set of fields, or there could be more. I tried a tablelayout, but couldn't get it set up right even when layout_span for Field 7. It worked ok, but when I tried to change the widths of Field 1 thru 5, the spanned row below it didn't conform to the changes (not like an HTML table would). The fields in each group need to lineup if there are more than one (see red lines in image). Can someone point me in the right direction on how I should approach this? Thanks

• Create "INSERT" statements from mySQL database in Java

  - by girdus

  Does anyone know of any good libraries or scripts out there which will allow me to point to any mySQL table and automatically get a list of all the INSERT statements for the data in the table? DdlUtils allows me to create an XML file from a database model but I would like to have it in INSERT statements format and preferably the ability to choose a couple of tables instead of dumping the entire database. Thanks. EDIT: I need it to be a Java API because I want to programatically call it from my Java method.

• Accessing hard-coded data in a C# application.

  - by haymansfield

  I'm trying to avaid hardcoding in a .net 2.0 soon to be 3.5 application. I have a large enumneration which I wish to map 1 to 1 to a set of strings. Each enumerated value will also map to 1 of 2 values indicating an action. The existing code does this with a big switch statement but this seems ugly to me. Is there a better way of storing and accessing the data? I've thought about resx files but when you consider that the designer file contains just as many hardcoded values it seems a little pointless. Is embedding an xml file in the assembly a good idea? Is a big switch statement not as bad as it seems? Is there a better solution?

• Nuget and Source Control Files to Exclude?

  - by Peter Kellner

  I know I should be using nuget more but at this point I don't completely understand the nuances so I still tend to either get source and build the project, then reference the project, or I create my own "dlls" folder and hand copy the dll's in. As part of my learning process, I'm trying to understand what is critical and what is not when using nuget. For example, I've done install-package restsharp and now when I check into source control, I get files like "packages/RestSharp.103.4/lib/net4/RestSharp.xml". I'm assuming that nuget will help me with upgrading and such and it needs to have certain meta data type files. My question is: Should I be ignoring any or all files in the "packages" directory? If so, what and why. Thanks

  - by sebbrousse

  I would like to set/change the delay of a File consumer at runtime through JMX.

• StructureMap: How can i unit test the registry class?

  - by Marius

  I have a registry class like this: public class StructureMapRegistry : Registry { public StructureMapRegistry() { For<IDateTimeProvider>().Singleton().Use<DateTimeProviderReturningDateTimeNow>(); } I want to test that the configuration is according to my intent, so i start writing a test: public class WhenConfiguringIOCContainer : Scenario { private TfsTimeMachine.Domain.StructureMapRegistry registry; private Container container; protected override void Given() { registry = new TfsTimeMachine.Domain.StructureMapRegistry(); container = new Container(); } protected override void When() { container.Configure(i => i.AddRegistry(registry)); } [Then] public void DateTimeProviderIsRegisteredAsSingleton() { // I want to say "verify that the container contains the expected type and that the expected type // is registered as a singleton } } How can verify that the registry is accoring to my expectations? Note: I introduced the container because I didn't see any sort of verification methods available on the Registry class. Idealy, I want to test on the registry class directly.

• acts_as_ferret with multiple hosts

  - by Nick

  I've got everything working with ferret and acts_as_ferret for development (or localhost DRb), but I can't get my multiple host deployment working. All of the remote systems get ECONNREFUSED when accessing the port. On the ferret server, the daemon is listening on localhost only despite the configuration listing the FQDN as the host. I also tried switching to a UNIX socket to share data between the ferret DRb daemon and the app code but it too gets ECONNREFUSED. (The socket is available to all of the machines via an NFS mount). Is there a better way to do this or should I be looking for another search indexer? Thanks.

• Upgrading IIS web sever framework 2.0 to 3.5 considerations

  - by Grant

  Hi, i will be responcible for upgrading an IIS web server from the Microsoft .NET framework v2.0 to v3.5. I am wondering if there is anything special i need to know or any caveats i should be aware of before proceding? The site gets a fair number of hits per day and I will be taking it down and performing the upgrade at an off-peak time. Aside from double clicking the installer is there anything i need to know? Will the server need to be rebooted afterwards, does the installer handle all of the configuration changes? etc.. Thanks.

• Binding to an XElement

  - by twreid

  I need help binding to an XElement. Basically I am making a editor for certain elements in a web.config and I extract them as XElements and my View binds to a Collection of DataItems which has a property that contains my XElement. When I do Text="{Binding Path=Data, Mode=OneWay, NotifyOnSourceUpdated=True}"/> I get all the text of the Element, but If I try Text="{Binding Path=Data.Elements[], Mode=OneWay, NotifyOnSourceUpdated=True}"/> It doesn't work the TextBox is empty. I am trying to find a way to Template different sections dynamically to make them easier to edit instead of editing raw XMl.

• Forms Authentication Across Applications Stopped Working

  - by colleski

  Hi, I have a .net 1.1 ASP application (domain.com) which has a .net 2 virtual directory (domain.com/v2) beneath it, both applications run within their own app pool on the same machine running IIS 6. The web.config files for both apps are setup for Forms Authentication as described here - http://msdn.microsoft.com/en-us/library/eb0zx8fc(v=VS.80).aspx. Users would be directed to the domain.com/v2/login.aspx page which would authenticate for both applications, this configuration has been working fine for the last few years until installing one of the recent Windows 2003 security updates today. Now after authenticating under /v2 users keep getting redirected back to domain.com/v2/Login.aspx as domain.com doesnt see them as authenticated anymore. Any ideas as to which security update would have caused this and if its possible to rollback? I've looked at a few suggestions on this (e.g. Cross app on subdomain form authentication not working) and other sites but no luck so far Any help would be appreciated. Thanks

• Can I learn the iPhone SDK and complete an app by September?

  - by Kuro

  Hi everyone, I'm wondering if it's realistically possible to learn the iPhone SDK and complete an app by the end of this summer. The app shouldn't be too difficult, it would just interact with my site's API and essentially just fetch, create, and edit resources. I already have a little experience with the SDK (and I'm comfortable with Objective-C), so I'm not completely new to it. Although here I things I don't know how to do and what I'd need to learn: Log in to my site using basic http authentication and store the user's username/password for all future requests Implement a toolbar at the bottom to navigate between different views Fetch and parse xml into list items Do POST/PUT requests to create/edit a resource on my server Are there any good resources available to learn how to do those tasks above? Thanks!
