  • Android ignoring my setWidth() and setHeight()

    - by popoffka
    So, why does this code: package org.popoffka.apicross; import android.app.Activity; import android.os.Bundle; import android.widget.Button; public class Game extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Button testButton = new Button(this); testButton.setBackgroundResource(R.drawable.cell); testButton.setWidth(20); testButton.setHeight(20); setContentView(testButton); } } ...produce this thing: http://i42.tinypic.com/2hgdzme.png even though there's a setWidth(20) and setHeight(20) in the code? (R.drawable.cell is actually a 20x20 PNG image containing a white cell with a silver border)

  • Passing arguments to java vm from NSIS script

    - by CodeBuddy
    I'm developing my first java application using Eclipse. I've recently needed to adjust the amount of memory allocated by passing -Xmx256M to the JVM. The application is currently package up as a runnable jar and installed using the NSIS. I'm having a problem passing arguments to the jar file once its installed. What is the common practice for doing this? Here is what I'm currently doing in my nsi file: CreateShortcut "$SMPROGRAMS\$StartMenuGroup\$(^Name).lnk" "$SYSDIR\javaw.exe" "-jar -Xmx256M $INSTDIR\Foo.jar" This results in the following being created as the shortcut Target on windows: C:\WINDOWS\system32\javaw.exe -jar -Xmx256M C:\Program Files\Foo\Foo.jar Unfortunately this does not work due to the space in C:\Program Files, If I change the link created manually to include quotes all is well: C:\WINDOWS\system32\javaw.exe -jar -Xmx256M "C:\Program Files\Foo\Foo.jar"

  • Trees and macros with tikz

    - by Tsf
    I am trying to build my trees using macros but I don't get the result I want. Here is a minimal example: \documentclass{article} \usepackage{tikz} \usetikzlibrary{trees} \newcommand{\LeafNode}[1]{% child {node {#1}} } \newcommand{\InnerNode}[3]{% child {node {#3} #1 #2 } } \begin{document} \begin{tikzpicture} \node (A) {A} \LeafNode{B} \LeafNode{C} ; \end{tikzpicture}% \hspace{2cm}% \begin{tikzpicture} \node (A) {A} \InnerNode{\LeafNode{D}}{\LeafNode{E}}{B} \LeafNode{C} ; \end{tikzpicture} \end{document} I expected this to produce two trees: A A / \ / \ B C B C / \ D E but I am getting: A | A B | | B D | | C C Am I missing something or there is no way to do it? BTW, if I omit the label on my root node, I get a PGF error: ! Package pgf Error: No shape named is known. -- Tsf

  • don't wanna lose data on Android after uninstalling

    - by soclose
    Hi, Now I make a trial application. I'd like to store IMEI and other info in Android permanently. And I don't want to lose them after uninstalling it. I tested with shared preference but it deletes after un-installation. SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); SharedPreferences.Editor editor = settings.edit(); editor.putBoolean("silentMode", true); // Commit the edits! editor.commit(); let me know where to store.

  • Is javac enough to build an OSGi bundle?

    - by Chatanga
    To produce a bundle from source using a tool such as javac, you need to provide it with a linear classpath. Unfortunately, it won't work in some situations still perfectly legal from an OSGi point of view: dependencies with embedded JAR in them; same packages contained by different dependencies. Since javac doesn't understand OSGi metadata, I won't be able to simply but the dependencies in a classpath. A finer package grained approach seems necessary. How this problem is addressed by people using OSGi in an automated process (continuous integration)? Strangely, there is a lot of resources on the web on how to create bundle JAR (creating the metadata, creating the JAR) provided you have the classes/inner JAR to put inside, but very few things on how actually get theses classes compiled.

  • Visual Studio 2008. MFC event wizard broken

    - by G Forty
    OK, so it's almost a programming question - The VS2008 dialog event wizard has stopped working. Double-clicking on a button in an MFC dialog project does not fire the wizard as usual and a right-click to get to the 'Add Event Handler...' shows a dialog with no message types. Further to this the MFC message mapping and virtual class listing that generally appears in the properties window (Alt + Enter) is now empty. Has anyone elese seen this and if so, how'd they fix it? I have 'repaired' my VS08 installation ... Thx++ Jerry

  • readobject method throws ClassNotFoundException

    - by eruina
    Hi all, I'm trying to pick up Java and wanted to test around with Java's client/server to make the client send a simple object of a self defined class(Message) over to the server. The problem was that I kept getting a ClassNotFoundException on the server side. I think the rest of the codes seem to be alright because other objects such as String can go through without problems. I had two different netbeans projects in different locations for client and server each. Each of them have their own copy of Message class under their respective packages. Message class implements Serializable. On the client side, I attempt to send a Message object through. On the server side, upon calling the readObject method, it seems to be finding Message class from the client's package instead of it's own. printStackTrace showed: "java.lang.ClassNotFoundException: client.Message" on the server side I have not even tried to cast or store the object received yet. Is there something I left out?

  • Correct way to (re)launch a Java application with hardware-dependent VM parameters?

    - by LowLevelAbstraction
    EDIT I don't want to use Java Web Start I've got a Java application that I'd like to run with different VM parameters depending on the amount of memory the system it is launched on has. For example if the machine has 1 GB of memory or less I'd like to pass "-Xmx200m" and "-Xmx400m" if it has 2 GB and "-Xmx800m" if it has 8 GB (these are just examples). Is there a portable way to do this? I've tried having a first tiny Java app (hence portable) that determines the amount of memory available and then launches a new Java app but I don't think this is very clean. As of now I've written Bash shell scripts that invoke the Java app with the correct parameters depending on the config but it only works on Linux on OS X. What is the correct way to solve this? Would application packager package ;) help ?

  • Using MinGW to compile a SFML project

    - by Kyle Martin
    Okay, so I have a C++ project that uses SFML, and I want to be able to compile it from the CMD using MinGW. I have it so I can compile.cpp's, however, I just need to know what more I have to do in order for it to work with SFML. I tried compiling it with CodeBlocks and MinGW, and it works fine, until I try to run it, at which point it tells me that sfml-system.dll is missing from my computer. Does this mean I installed it incorrectly? I followed the CodeBlocks installation down to the letter, from what I could tell... I put the include\SFML in the include\ of MinGW, and I put all the *.a's from lib\ into the \lib of MinGW as well. Thank you for the help you can give! Kyle

  • Active Directory: User UPN or DN for NTLM name, using pure LDAP?

    - by Bernd Haug
    I have a Java app that can authenticate to LDAP by logging users into the AD LDAP server with the NTLM name (which they are used to - this is a requirement). I now also need to do authorization, and hence need to find a forest-unique identifier for the user (DN or UPN should work), from which I can further query the directory. The method needs to be absolutely portable, even if the AD is structured in an unusual fashion, otherwise I could just do a string replacement and search for a UPN of "${ntlm-user}@${ntlm-domain}.${configured-trailing-domain}" How can I do this, using pure LDAP? Currently, I'm using the java.naming.directory package, which I'd like to keep using, since it doesn't throw up problems when not binding with a DN but logging in with an NTLM name?

  • How do I structure a GWT project?

    - by smaye81
    Hello, I have followed the basic GWT tutorial for creating a project in Eclipse. Now, I am trying to build off what I learned in the tutorial. I created a static utility class to perform some database connection logic. However, when I try to compile I get: [ERROR] Line 46: No source code is available for type com.sample.server.ConnectionUtil; did you forget to inherit a required module? Where can I put simple classes that I've created on my own? Do they have to be outside the package structure of the basic module, 'com.sample'? Or do I have to specify a whole new module in the gwt.xml file and inherit from that? There has to be something simple I'm missing.

  • ASP.NET + GoDaddy Free Hosting?

    - by Sahat
    Has anyone successfully been able to deploy ASP.NET website to GoDaddy's free hosting? I am talking about free hosting that comes with a domain package from GoDaddy. The catch of the free hosting is having an annoying Google Ads banner in a frame on top of the page. I've searched Google, stackoverflow and GoDaddy forums but I can't find anywhere the solution to my problem. When I upload a ASP.NET website to GoDaddy, it gives me an error - something about TrustLevel. Someone told me that by default asp.net websites have Full Trust Level which GoDaddy doesn't allow. I've even tried changing Trust Level to Medium manually, but with no luck. What may be the problem?

  • Web app - Biometric system connection

    - by DMin
    Hi, I will be developing an application for a club where they will have visitors use biometric systems(finger print) or magnetic cards to mark their attendance. This application is planned as a web app, made using PHP/MySQL/Javascript. It does a lot of other things as well. What I wanted to find out is how is the interface between Biometric/Megnetic Card systems to a web app done? I've never worked on this and am hoping if someone who has experience with this can throw some light on this as to how this could be accomplished. Any pointers will be appreciated. (I'm afraid there's got to be some form of application installed on a pc that would interface with the hardware and probably makes calls to the web app. But, if there was a way to connect it to the web app directly, then the app would be easy to deploy to any location with minimal installation.) Thanks! :)

  • Usage CursorLoader without ContentProvider

    - by sealskej
    Android SDK documentation says that startManagingCursor() method is depracated: This method is deprecated. Use the new CursorLoader class with LoaderManager instead; this is also available on older platforms through the Android compatibility package. This method allows the activity to take care of managing the given Cursor's lifecycle for you based on the activity's lifecycle. That is, when the activity is stopped it will automatically call deactivate() on the given Cursor, and when it is later restarted it will call requery() for you. When the activity is destroyed, all managed Cursors will be closed automatically. If you are targeting HONEYCOMB or later, consider instead using LoaderManager instead, available via getLoaderManager() So I would like to use CursorLoader. But how can I use it with custom CursorAdapter and without ContentProvider, when I needs URI in constructor of CursorLoader?

  • Problem running gems in OS X

    - by akarnid
    I'm running Snow Leopard, and installed a custom built Ruby according to the guide here: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard . My ruby binary lives in usr/local/bin/ruby and my gems are installed in /usr/local/bin/gem . My gem env looks like so: RUBY VERSION: 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0] - INSTALLATION DIRECTORY: /Library/Ruby/Gems/1.8 - RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby - EXECUTABLE DIRECTORY: /usr/bin I think I may have borked the install since all actions taked on gems give the error: ERROR: While executing gem ... (Errno::EEXIST) File exists - /usr/local/bin/ruby How do you edit the environment variables for the gem environment? And for those of you on OS X and using ruby AND gems, what did you use to get yourself up and running? I'm thinking of just nuking everything and starting anew.

  • Extending an entity

    - by Kim L
    I have class named AbstractUser, which is annotated with @MappedSuperclass. Then I have a class named User (@Entity) which extends AbstractUser. Both of these exist in a package named foo.bar.framework. When I use these two classes, everything works just fine. But now I've imported a jar containing these files to another project. I'd like to reuse the User class and expand it with a few additional fields. I thought that @Entity public class User extends foo.bar.framework.User would do the trick, but I found out that this implementation of the User only inherits the fields from AbstractUser, but nothing from foo.bar.framework.User. The question is, how can I get my second User class to inherit all the fields from the first User entity class? Both User class implementation have different table names defined with @Table(name = "name").

  • Can a 32-bit RHEL4 userland work with a 64-bit kernel?

    - by James
    Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

  • Admin required for Visual Studio 2008 Setup Project

    - by user54064
    I have a VS 2008 Setup Project that is installing a very simple application in the local user's App Folder. When the Setup Project runs, it is requiring the Admin to login to run it. How can I allow a Standard User to run the installation. There are no Prerequisites. The MSI file is the only file to be run (no Setup.exe). I have signed the msi with a certificate that is installed on the user's machine as Trusted. I just can't get rid of the Admin login requirement.

  • MSXML2.ServerXMLHTTP.4.0 Source?

    - by Frank V
    Where does the object "MSXML2.ServerXMLHTTP.4.0" come from? Which install package? I'm attempting to do the following: Set oXMLHTTP = CreateObject("MSXML2.ServerXMLHTTP.4.0") This attempt fails on my development machine (no object is returned) but it is successful on my collage's development machine. Obviously he has something installed that I don't or vice versa but where does this object, dll, etc come from? What would I need to install to get this call to work. For the record, changing the object to a different version isn't an option because code that this depends on was tested for several days against this specific version. We'd have to go back and test again... To expand on this question, how can I tell which version of MS XML is currently installed?

  • Sharing a mex64 file across computers

    - by Shaihi
    I have a mex64 dll compiled on my machine. I used Matlab 2009b with VS2008 Pro to compile the dll. The dll works fine on my Matlab installation. I want a colleague to use the dll so I sent it to him and he gets the following error message when trying to use the dll: ??? Invalid MEX-file 'filename.mexw64': The specified module could not be found. My current assumption is that this is caused because he uses an older Matlab version or missing a dll that I have. I ran dependency checker and asked him to check that he has all the listed dlls. I am still waiting for him to confirm his Matlab version. What other reasons can cause this and can the Matlab version make a difference? (I mean R2009a when I have R2009B and not a huge version diff)

  • Mysqld Crashes immediately on running on Windows 7...?

    - by Cyril Gupta
    I am trying to run MySql 5.1 on Windows 7 Home Premium 64 bit. I have downloaded the MSI installer from the MYSql website and installed it. The installation is successful, but the service does not start. If I try to run MySql manually using the mysqld executable, it crashes immediately on running (error: mysqld.exe has stopped working). Earlier mysql was running on the machine, but I had some problem with it (wasn't executing big queries) and installed it again which somehow broke the program. I had installed it to work as a service which started giving me this isse, and now it won't work even if I don't install it as a service. I have tried removing the mysql folder and re-installing. Is there somewhere else where Mysql saves configuration info or other data? Has anyone else found this problem and solved it? How can I find out why the process is failing to run?

  • javac - differences between classpath and sourcepath options

    - by Alex
    Hi, I read the Sun documentation and a lot of Q/A on SO but I'm still a little bit confuse regarding the differences between the javac options -cp and -sourcepath. Let say I have this directory structure: c:\Java\project1\src (where the .java source files are) c:\Java\project1\bin (where the .class will be or are already) The class source MainClass.java is in a package "com.mypackage" and the directory structure is ok in src. I'm in the project1 directory. I run c:\Java\Project1\javac -d bin -sourcepath src src/com/mypackage/MainClass.java or c:\Java\Project1\javac -d bin -classpath src src/com/mypackage/MainClass.java and I obtain the same result. In verbose mode, the search path for source files is src in both cases. If anybody could help me figure out the specifics of these options, it would be great. Thank you.
