• Strange bug with PHP on Windows 7

  - by chessweb

  This is the configuration: Windows 7 Home Premium, XAMPP 1.7.3 (Apache 2.2.14 , PHP 5.3.1), Firefox 3.6 This is the PHP-code in a file named 'test.php' in htdocs: <?php echo('04556-8978765'); ?> On http://localhost/test.php I would expect to see the string 04556-8978765 in the browser. This is not what happens, though. The string appears for a short time and then it disappears altogether. Firebug shows an empty body-tag. However, when I look at page source, the string is there alright. When I change the string in the echo-statement to e.g. 4556-8978765, everything is fine. Internet Explorer 8 does not show this strange behavior. I could not reproduce this with the same Apache/PHP/Firefox configuration on Windows XP. '04556-8978765' is by no means unique. The couple '02065-96047' and '02065-9604' behave exactly the same. Can anybody reproduce this and offer an explanation as to what is going on? PS: If you can not see the string '04556-8978765' in the echo-statement above, look at this post with IE8.

• How the Google Chrome Linux version handles automatic version updation

  - by AJ

  Hello, Can some one tell me how the Chrome's Linux beta version carry out automatic version updation using debian package manager. I need to implement something similar to my application on linux and information provided here would be of lot of help. I am currently checking out the postinst script present in the debian control package and I can see Chrome uses PGP publish/subscribe model for getting automated version updates in Linux. I just clear understanding of how that works. Any help would be greatly appreciated. Thanks

• Generate Spring bean definition from a Java object

  - by joeslice

  Let's suggest that I have a bean defined in Spring: <bean id="neatBean" class="com..." abstract="true">...</bean> Then we have many clients, each of which have slightly different configuration for their 'neatBean'. The old way we would do it was to have a new file for each client (e.g., clientX_NeatFeature.xml) that contained a bunch of beans for this client (these are hand-edited and part of the code base): <bean id="clientXNeatBean" parent="neatBean"> <property id="whatever" value="something"/> </bean> Now, I want to have a UI where we can edit and redefine a client's neatBean on the fly. My question is: given a neatBean, and a UI that can 'override' properties of this bean, what would be a straightforward way to serialize this to an XML file as we do [manually] today? For example, if the user set property whatever to be "17" for client Y, I'd want to generate: <bean id="clientYNeatBean" parent="neatBean"> <property id="whatever" value="17"/> </bean> Note that moving this configuration to a different format (e.g., database, other-schema'd-xml) is an option, but not really an answer to the question at hand.

• Linking Error Building 64bit Qt app on 32bit XP machine.

  - by photo_tom

  I'm trying to build a 64 bit version of my application (and yes I really do need the memory) on my 32bit xp dev box for production testing on our Vista64 server. Previously, I have built w/o any errors the Qt 4.6.2 DLL's in 64 bit mode. That step went vary smooth. Just to get started in building production, I'm trying to rebuild Qt's Star Delegate demo in 64bit mode. I converted the 32bit to 64bit app by changing the application configuration and adjusting the library's to the 64bit venisons. Now, when I go to link, I'm getting the following error when I link 1>------ Build started: Project: stardelegate, Configuration: Release x64 ------ 1>Linking... 1>MSVCRT.lib(crtexew.obj) : error LNK2001: unresolved external symbol WinMain 1>release64\stardelegate.exe : fatal error LNK1120: 1 unresolved externals Suggestions? edit - After some more searching, discovered if I link as a console app it will work and run. But not as a windows app. And I don't have this problem in 32 bit mode.

• VS 2010 IDE 2GB limt

  - by user561732

  I am using VS 2010 on a win 7 64 bit system with 8 GB of memory. My application is 32 bit. While in the VS 2010 .Net IDE, the app shows up in the Windows task manager as "MyApp.vshost.exe *32" while the VS IDE itself shows up as "devenv.exe *32". I checked and it appears that the VS 2010 IDE file (devenv.exe) is complied with the /LargeAddressAware flag. However, when debugging large models, the IDE fails with an Out of memory exception. In the Windows Task manager, the "MyApp.vshost.exe *32" process indicates about 1400 MB of memory usage (while the "devenv.exe *32" process is well under 500 MB). Is it possible to set the "MyApp.vshost.exe *32" process to be /LargeAddressAware in order to avoid this out of memory situation? If so, how can this be done in the IDE. While setting the final application binary to be /LargeAddressAware would work, I still need to be able to debug the app in the IDE with these type of large models. I should also note that my app has a deep object hierarchy with many collections that together required a lot of memory. However, my issue is not related to trying to create say 1 large array that requires greater then 2 GB of memory etc. I should note that I am able to run the same app in the VB6 IDE and not get an out of memory situation as long as the VB6 IDE is made /LargeAddressAware. In the case of VB6, the IDE and the app being debugged are part of the same process (and not split into 2 as is the case with VS 2010.) The VB6 process can be larger then 3 GB without running into out of memory issues. Ultimately, my objective is to have my app run completely in 64 bit to access more memory. I am hoping that in such cases, the IDE will allow the debugging process to exceed 2 GB without crashing (and certainly more then 1.4 GB as is the current case). However, for now, while 95% of my app is 64 bit, I am calling a legacy COM 32 bit DLL and as such, my entire app is forced to still run in 32 bit mode until I replace that DLL.

• Why is Java layout system so complicated to work with?

  - by Tom Brito

  Some points that make java swing layout system a nightmare: There's thousands of properties; Even if you learn all the properties, each layout manager ignores some properties; The only existing good RAD tool (NetBeans) does not work well; Layout managers behave different with components and containers inside it.

  - by Undgerman

  I am trying to make a ranking manager for a small project.The totals are stored in the database.I can easily get the max and min using mysql and also arrange the records descending.The problem comes in when there is a tie.I need to show a tie in the form:1,2,3,3,4,5,6,7,7,7,7, etc.The repeated numbers will show the ties.I have been thinking of ways of achieving the above but i need more ideas;mine is seems long and complicated. Can anybody share his/her idea of doing the ties.

• Pass command line arguments to JUnit test case being run programmatically

  - by __nv__

  I am attempting to run a JUnit Test from a Java Class with: JUnitCore core = new JUnitCore(); core.addListener(new RunListener()); core.run(classToRun); Problem is my JUnit test requires a database connection that is currently hardcoded in the JUnit test itself. What I am looking for is a way to run the JUnit test programmatically(above) but pass a database connection to it that I create in my Java Class that runs the test, and not hardcoded within the JUnit class. Basically something like JUnitCore core = new JUnitCore(); core.addListener(new RunListener()); core.addParameters(java.sql.Connection); core.run(classToRun); Then within the classToRun: @Test Public void Test1(Connection dbConnection){ Statement st = dbConnection.createStatement(); ResultSet rs = st.executeQuery("select total from dual"); rs.next(); String myTotal = rs.getString("TOTAL"); //btw my tests are selenium testcases:) selenium.isTextPresent(myTotal); } I know about The @Parameters, but it doesn't seem applicable here as it is more for running the same test case multiple times with differing values. I want all of my test cases to share a database connection that I pass in through a configuration file to my java client that then runs those test cases (also passed in through the configuration file). Is this possible? P.S. I understand this seems like an odd way of doing things.

• Maven exec bash script and save output as property

  - by djechlin

  I'm wondering if there exists a Maven plugin that runs a bash script and saves the results of it into a property. My actual use case is to get the git source version. I found one plugin available online but it didn't look well tested, and it occurred to me that a plugin as simple as the one in the title of this post is all I need. Plugin would look something like: <plugin>maven-run-script-plugin> <phase>process-resources</phase> <!-- not sure where most intelligent --> <configuration> <script>"git rev-parse HEAD"</script> <!-- must run from build directory --> <targetProperty>"properties.gitVersion"</targetProperty> </configuration> </plugin> Of course necessary to make sure this happens before the property will be needed, and in my case I want to use this property to process a source file.

• Make service indepented from activity (Android).

  - by shuwo

  I have an activity with two buttons, start and stop. If the user press the start button a service is created using Context.startService. And the stop button calls Context.stopService. I want the stop button to be the only way to destroy the service. Now, if i end the activity using a task manager, the service is killed as well. Is there any way to avoid this?

• PHP session corrupt

  - by Baversjo

  Using symfony framework 1.4 I have created a website. I'm using sfguard for authentication. Now, this is working great on WAMP (windows). I can login to several accounts on different browsers and use the website. I have ubuntu server 9.10 running apache (everything up to date and default configuration). On my server, when I login to the website in one browser it works great. When I on my other computer login with another user account on the public website, the login is successful. But when I refresh/go to another page the first user is shown as logged in instead! Also, when I press logout, It's not showing that I'm logged out after page load. When I press f5 again I'm logged out. As mentioned, all this works as expected on my local installation. I'm thinking there something wrong with my PHP session configuration on my ubuntu server, but I've never touched it.. Please help me. This is a school project and I'm presenting it today :(

• How do I conditionally compile C code snippets to my Perl module?

  - by mobrule

  I have a module that will target several different operating systems and configurations. Sometimes, some C code can make this module's task a little easier, so I have some C functions that I would like to bind the code. I don't have to bind the C functions -- I can't guarantee that the end-user even has a C compiler, for instance, and it's generally not a problem to failover gracefully to a pure Perl way of accomplishing the same thing -- but it would be nice if I could call the C functions from the Perl script. Still with me? Here's another tricky part. Just about all of the C code is system specific -- a function written for Windows won't compile on Linux and vice-versa, and the function that does a similar thing on Solaris will look totally different. #include <some/Windows/headerfile.h> int foo_for_Windows_c(int a,double b) { do_windows_stuff(); return 42; } #include <path/to/linux/headerfile.h> int foo_for_linux_c(int a,double b) { do_linux_stuff(7); return 42; } Furthermore, even for native code that targets the same system, it's possible that only some of them can be compiled on any particular configuration. #include <some/headerfile/that/might/not/even/exist.h> int bar_for_solaris_c(int a,double b) { call_solaris_library_that_might_be_installed_here(11); return 19; } But ideally we could still use the C functions that would compile with that configuration. So my questions are: how can I compile C functions conditionally (compile only the code that is appropriate for the current value of $^O)? how can I compile C functions individually (some functions might not compile, but we still want to use the ones that can)? can I do this at build-time (while the end-user is installing the module) or at run-time (with Inline::C, for example)? Which way is better? how would I tell which functions were successfully compiled and are available for use from Perl? All thoughts appreciated!

• How to avoid accidental deletions of databases in Lotus Notes?

  - by Saili

  I have always worried about users deleting lotus notes databases by accident. We had one such case last week and I want to know how we can lock the databases so that users cannot delete them. Is there a way in Lotus Notes - either at the Db level or server level where we can set up the database so that only the administer of the db or the user with Manager access can delete the database? Thanks!

• How do I execute a program using Maven?

  - by Will

  I would like to have a Maven goal trigger the execution of a java class. I'm trying to migrate over a Makefile with the lines: neotest: mvn exec:java -Dexec.mainClass="org.dhappy.test.NeoTraverse" And I would like mvn neotest to produce what make neotest does currently. Neither the exec plugin documentation nor the Maven Ant tasks pages had any sort of straightforward example. Currently, I'm at: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.1</version> <executions><execution> <goals><goal>java</goal></goals> </execution></executions> <configuration> <mainClass>org.dhappy.test.NeoTraverse</mainClass> </configuration> </plugin> I don't know how to trigger the plugin from the command line, though.

  I'm still new to Android, so, I'm still not so familiar with its libraries and APIs. My first major project is a download manager which supports segmented downloading. I could already download files, but, I still have no idea on how or where to start for segmented downloading. I have already browsed a lot of threads, but I really couldn't find any article or thread about segmented downloading in Android. Can anyone please help me?
