  • Velocity Templates - New Line.

    - by LdSe
    Hello all, I've been working with Apache's Velocity engine and a custom template. The thing is, that I haven't been able to generate a String with the corresponding line breaks. I tried almost everything that I found, such as using $esc.n and $esc.newline (I'm already using escape tools on my project) but it seems that the version I'm currently using doesn't support it (1.4), checked if putting '\n', '\\n' and even '\\\n' would work, but same thing. Does anyone have any solution to this? Thanks a lot in advance! Regards.

  • level of control of the os on the phone hardware

    - by gurnisht
    Hello. I am new to Android and mobile phones development. I want to develop an application that needs to have a total control over the "phone" of the smartphone, i.e. controlling all the communication of the GSM chip with the cellular system, accessing the SIM card identity that it sends (encrypted) to the cellular system, disabling the cellular antenna and resuming it back, and more of that kind... Can it be done with Android? Does the software (OS) have control over all of the phone components in a smartphone, or there are some parts that are done in the hardware level only? (I guess that the Android API won't enable me to do everything i want, but even theoretically is it possible if I recompile the OS after making the changes there?) Thanks!

  • can't make svn store password, even though the configuration is set to allow it

    - by davka
    did everything the book says, i.e. removed the authentication files from .subversion/auth, and explicitly set the relevant config parameters to 'yes' even though this is a default, and yet the shell svn commands ask for password each time. The repository is on cvsdude.com, the client is linux. I also use the subclipse plugin that caches the password ok. I vaguely remember that when I started working with it, the command asked interactively if I wanted to save clear password, and I said no. Can this choice be stored somewhere and take precedence over the configuration? Thanks!

  • iPad --- managedObject problem when [self.tableViewSection reloadData]

    - by user345777
    Hi , I am creating a news aggregator application that fetches a xml feed every 4 minutes. After the xml is loaded, I clear everything by deleting all the objects in the database, then save the new objects back into the database. I then call [self.tableViewSection reloadData]; to reload the tableView. Thats when I get a problem. As soon as the code gets to a section where i access the new [[managedObject valueForKey:@"event_text"] description] content it fails with a : * Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x4b3f6a0 '' Now from the flow I described on top, it seems odd to me that the tableView is populated properly the next time i launch the application, with the "new" data I fetched in the previous session. So its not that data thats corrupt , but seems to me something goes wrong when I refetch the managedObject after saving new data. Also keep in mind thats this app runs fine on the iPhone, its the iPad thats is giving me this problem.

  • Toolbar disappeared in Visual Studio

    - by j-t-s
    Visual Studio ate my toolbar, I opened a solution for a project I've been working on for a few months, and the toolbar has 135 buttons on it, and while it was loading, the whole toolbar flickered like it was trying to give me a seizure or something, and then it dissappeared. Now when I click Debug, it won't let me do it because all the resources are missing!? I'm using: Visual Studio 2010 C# Express Windows 7 Home Premium 64-bit. I have searched Google and found nothing related. I'm hoping that Visual Studio can also somehow make bowel movements so I can find those missing resources and put everything back together again, but I don't think that's a likely scenario... Has anybody ever experienced this before, and if so, are there any updates/fixes for this?

  • In few words, what can be said about Func<>

    - by Richard77
    Hello, I've been seing Func< for sometime now, and I've manage to avoid it (for now). But, now it looks like I can't dodge it forever. For instance, I tried Dynamic Linq, but almost everything was in terms of Func<. I've tried one of my book (C# 2008/Deitel&Deitel) and also MSDN but I'm not getting it yet. They all jump straight in the subject. What can be said (in few words) about Func< Can I get some links on the web that can get me started on that matter? Thanks for helping

  • Issues with start activity for result

    - by rodkarom
    I have written an Activity using Theme.Holo.Dialog so that it works as an AlertDialog as a login/password notice. I've started this activity with startActivityForResult(...) using a request code I defined. The thing is, whenever I start the activity ´onActivityResult(...)´ is triggered immediately, the buttons get loaded and everything, but once I press them, even though I know the Activity is working because login does happen, there is no result sent back to the first Activity and I am calling setResult(...) and finish() after the buttons are pressed. Thanks in advance, first time using startActivityForResult so I'm sure I must be missing something.

  • What happens when a OSGi service using JNI is unregistered while in use?

    - by schngrg
    As I understand, OSGi services can be unregistered anytime, including when they are in use. Consider an OSGi service which internally makes a long-running JNI call. And while that JNI call is executing, the service is unregistered by OSGi. Will the JNI call be allowed to finish or terminated mid-way? What if it was just a normal non-jni long running Java call? Will that call be allowed to finish execution or will OSGi terminate everything immediately and unregister? What is the expected behavior in such a case? Does the expected behavior depend on if the service was loaded using a 'tracker' or not? SG

  • Importing specific ( in my case - Themes.ThemesService.ThemesEnabled ) function / procedure in runet

    - by HX_unbanned
    Hi again :) I think subject tells everything ... I need this method only. No need to waste about 6Mb of included unit if only thing I need is one method from that unit ( Themes ) ... I was thinking of UxTheme unit, but it did not contain proper function. What Windows DLL do I need to import and what API function this method stands for? Thanks. P.S. Question is intended to cover not only this particular method, but others too as I will need to do same in MSXML and MM units ...

  • TDBGrid columns design time or run time?

    - by Mawg
    I am using TDBGrid for the first time. I didn't even notice the Columns property in the object inspector and everything went just fine: the grid was filled. Then I saw the Columns property and tried it. When I use the object insector to add items to the Columns property of the grid, they do not all of them show up at run time. To me, it looks like the FieldName property is important. It looks like it is correct, but there are no values in some columns. If I leave this property blank (no columns at all) it seems that the control populates it itself at run time and I do see all the columns. I could live with that. When I set column titles at run time it works, but setting column width does not.

  • multiple threads writting to a same socket problem

    - by alex
    Hi: My program uses sockets for inter-process communication. There is one server listening on a socket port(B) on localhost waiting for a list of TCP clients to connect. And on the other end of the server is another a socket(A) that sends out data to internet. The server is designed to take everything the TCP clients send him and forward to a server on the internet. My question is if two of the TCP clients happened to send data at the same time, is this going to be a problem for the server's outgoing socket(A)? Thanks

  • NullPointerException when accessing image files in a .jar file

    - by user548240
    Hi, I have pretty much tried everything but still have this same problem. I have the following setup: I have a images.jar containing a folder called 'images' in which there are multiple image files. I add images.jar to the java build path of the project in eclipse, and i've been trying to use the following code to access the individual images in the jar: URL url = this.getClass().getResource("images/a.png"); ImageIcon icon = new ImageIcon (url); Unfortunately, the URL object is always NULL. I don't think this has anything to do with where I put images.jar file as it is added to the classpath in eclipse. I have also tried using the path '/images/a.png', but still the same problem. Any suggestion would be extremely welcome! Thanks.

  • Cross domain secure cookie usage?

    - by asdasda
    I have a website that came with a SSL site for HTTPS but its on a different server. Example being my website: http://example.com my SSL site: http://myhostingcompany.com/~myuseraccount/ So I can do transactions over HTTPS and we have user accounts and everything but it is located on a different domain. The cookie domain is set for that one. Is there a way I can check on my actual site to see if a cookie is set for the other one? And possibly grab its data and auth a user? I think this violates a major principle of security and can't be done for good reasons, but am i wrong? is this possible?

  • Do you have to use zf tool when creating controller, model, action etc... in zend framework

    - by Andy
    I am using zend framework 1.10. I use the zf tool to create controllers, actions and everything else. It is handy, but I am now seeing that when it modifies existing controller files to add new actions it realigns my code and removes some function closing brackets. I then see all these errors in eclipse. I see that everytime i issue a zf command it modifies the .zfproject file. Is this file critical at all? I want to be able to create whatever I want by myself without the zf tool and worrying about that .zfproject file.

  • Getting the size of an opening window in WebKit

    - by ThereSkippy
    Hi, I'm implementing a "WebKit Browser In An Application" which basically embeds WebViews in Qt widgets (we're using the WebKit browser instead of Qt's since it's stabler and more up-to-date). So far everything's great, until someone clicks on a link which invokes a Javascript "Window.open" function with a custom width and height for the new window. I've set the various delegates for the parent window: setFrameLoadDelegate, setResourceLoadDelegate, setPolicyDelegate, and setUIDelegate. I am getting a createWebViewWithRequest in the UI delegate as expected when the window opens (with a null request, as others have noted). I then get a decidePolicyForNavigationAction for the new window, but it doesn't have the proposed window's width or height. I NEVER get a decidePolicyForNewWindowAction for JavaScript window.open (also noted by others). So I'm at a loss. Is there a way to get this information so I can set the Qt Widget's size correctly?

  • Using flash for videoconferencing

    - by PHP
    Hi I'd like to set up a videoconferencing (1-1 initially) system using Flash as the client. I've tried some web searches but couldn't find much; any pointers on the following would be great: Does the standard browser Flash 10 plugin contain everything needed for P2P video conferencing, or is server support needed? Does anyone have any experience of opensource server videoconferencing products to be used with Flash on the browser side? E.g. would Asterisk work? Something like http://www.red5chat.com/ ? (ideally I'd like to be able to record videoconferences also). Any licencing issues? Many thanks

  • Android App crashing on one device only

    - by Daniel1402
    I am working on a new game that works perfectly on my test devices, 7-inch tablets and smartphones. But it crashes on my Galaxy Tab2 10-inch tablet with an Out of memory error. It always crashes when I start to play a second game! I have spent a full week checking the codes and I cannot figure out what is wrong. When I play from the menu screen, everything works fine. When I want to replay a game level from the level screen, the game will crash on the second launch. The level screen is made of 3 fragments, each with 32 buttons (4kB in size). I tried to keep only one fragment in memory with viewPager.setOffscreenPageLimit(1); but it does not solve the problem. Could someone stir me in some direction as to where to look for the potential problem? Why is the 10-inch tablet the only one to crash? Thanks.

  • The best approach to customize Bootstrap Less files and keep it easy to be updated to future versions

    - by user322896
    I'm wondering what the best way would be to customize the less files in Bootstrap and, at the mean time, keep it easy to be updated to future Bootstrap versions. It's straightforward to just modify the less files, but the problem is that when the next version of Bootstrap comes out, it might be painful to upgrade (because all the changes are already deeply mixed with the original sources.) Another approach would be similar to the open closed principle, that is, keeping the original less files unchanged, and adding my customized less files to overwrite the CSS rules I need. When Bootstrap gets updated, (hopefully) I can simply replace the less files and everything would work magically. However, regardless of the correctness of my assumption, the same CSS rules would be scattered in even more places and hard to manage. Also, the more we overwrite the CSS (not for compatibility or other purposes), the more bandwidth we waste. I know this highly depends on how the author of Bootstrap would handle the structure of the framework or even the naming of CSS rules, but I'd still like to hear everybody's opinions. Thanks.

  • OpenGL multitexture tessellation

    - by user1715296
    I have to tessellate some surface in OpenGL with rectangular textures. Let it be a single triangle for simplicity. The textures touch each other by sides, and do not overlap. That is done by setting GL_TEXTURE_WRAP_S and GL_TEXTURE_WRAP_T to GL_CLAMP_TO_BORDER and adjusting texture coords properly. Everything goes fine while GL_TEXTURE_MIN_FILTER and GL_TEXTURE_MAG_FILTER is set to GL_NEAREST, but when I want to apply GL_LINEAR filering and/or anisotropic filtering following arifact apperas: textures border pixel's alpha gradually fall to transparent, so that line of background color is visible between neighbouring textures. How can I avoid this artifact without merging multiple textures to one while linear filtering is preserved?
