• Is there a work around for setAppCacheEnabled on WebView for an Android 2.1 application causing the

  - by Kevin

  We have an HTML 5.0 web application that we ported to Android. It's our intention to run this in a Native Wrapper. Our application uses the ApplicationCache to run offline. This works find when running under the browser. While being hosted in a WebView within a native application, after the last file is downloaded and stored in the ApplicationCache from the manifest the application is terminated and does a core dump. This appears to be a documented bug. http://code.google.com/p/android/issues/detail?id=7939 Has anyone doing anything similar found a work around for this issue?

• Creating a folder inside Mac OS App

  - by Negative Zero

  I want a an app that is "self-contained" (I don't know if i use the right word. "putting the app into trash bin will remove everything" is what I meant). But the app requires some resources to run. I usually put those resources into a folder. I want to move those resources into the App folder ( package contents). Can I do that? Is it a good practice to do that? When I test the app directly running from Xcode, the App runs fine. But if i run it from finder, the app will say fails to create resources folder because permission denied. I checked the app's folder permission - User(me) has read/write access. I am wondering what is causing this different behavior. The last option is to use Application Support folder, but I don't want to leave trails when user deletes the app. Can someone help me out here?

• Is there any difference between SQL running in code vs the MySQL command line?

  - by MJB

  I have a SQL update statement I am running from inside a PHP program. It is prepared and then executed. When I run it in PHP, it reports a constraint violation. When I run the exact same statement from the command line (which I am getting via dBug()), it works with no errors. This sounds impossible, so I keep looking for differences between the statements. The only thing I can see is that when I execute it with an array of arguments, they all appear to be chars, when some should be integers. Any suggestions for where to look? I can post the code, but that does not seem like it would be helpful, because the code works.

• T-SQL Specific Syntax problem (Simple no doubt)

  - by Yoda

  Hi guys, I have an issue with a query I'm trying to run on some data, I guess the place to start is to describe the data. Ok so I have a list of email addresses, each email address has a unique ID and an account ID Also in my tables I have a set number which auto incrememnts, this will allow me to target duplicate email addresses What I need to do is something like this. Insert into duplicates (EMAIL,ACCOUNTID,ID) SELECT Email,AccountID,ID FROM EmailAddresses Group by Email,AccountID Having Count(email)>1 Order by AccountID, Email So essentially I want to select all duplicate email addresses and insert them (and their relative fields) into a new table broken down by accountID so I can run some further querys on it. I have been battling with this for way too long and could just use a fresh perspective. Cheers in advance

• C++ execution error: This application has requested the Runtime to terminate it in an unusual way.

  - by user1846547

  I am trying to run a C++ program and am getting the following error message when I try to run the program using - Codeblocks IDE and SQL API: "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Process returned 3 (0x3) execution time : 7.547 s Press any key to continue." The program compiles fine but on execution throws this error. My current OS is Windows server 2003 - SP2 (32 bit). Also program compiles and executes fine on Windows XP (32 bit) without any hassles. I checked the services (services.msc) running on my XP machine and compared with Windows server 2003 and found the settings same. Can someone please have a look and help me resolve the issue? thanks, Dhruv

• Handling file upload in a non-blocking manner

  - by Kaliyug Antagonist

  The background thread is here Just to make objective clear - the user will upload a large file and must be redirected immediately to another page for proceeding different operations. But the file being large, will take time to be read from the controller's InputStream. So I unwillingly decided to fork a new Thread to handle this I/O. The code is as follows : The controller servlet /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse * response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub System.out.println("In Controller.doPost(...)"); TempModel tempModel = new TempModel(); tempModel.uploadSegYFile(request, response); System.out.println("Forwarding to Accepted.jsp"); /*try { Thread.sleep(1000 * 60); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); }*/ request.getRequestDispatcher("/jsp/Accepted.jsp").forward(request, response); } The model class package com.model; import java.io.IOException; import java.util.concurrent.ExecutionException; import java.util.concurrent.Future; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.utils.ProcessUtils; public class TempModel { public void uploadSegYFile(HttpServletRequest request, HttpServletResponse response) { // TODO Auto-generated method stub System.out.println("In TempModel.uploadSegYFile(...)"); /* * Trigger the upload/processing code in a thread, return immediately * and notify when the thread completes */ try { FileUploaderRunnable fileUploadRunnable = new FileUploaderRunnable( request.getInputStream()); /* * Future<FileUploaderRunnable> future = ProcessUtils.submitTask( * fileUploadRunnable, fileUploadRunnable); * * FileUploaderRunnable processed = future.get(); * * System.out.println("Is file uploaded : " + * processed.isFileUploaded()); */ Thread uploadThread = new Thread(fileUploadRunnable); uploadThread.start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } /* * catch (InterruptedException e) { // TODO Auto-generated catch block * e.printStackTrace(); } catch (ExecutionException e) { // TODO * Auto-generated catch block e.printStackTrace(); } */ System.out.println("Returning from TempModel.uploadSegYFile(...)"); } } The Runnable package com.model; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.nio.ByteBuffer; import java.nio.channels.Channels; import java.nio.channels.ReadableByteChannel; public class FileUploaderRunnable implements Runnable { private boolean isFileUploaded = false; private InputStream inputStream = null; public FileUploaderRunnable(InputStream inputStream) { // TODO Auto-generated constructor stub this.inputStream = inputStream; } public void run() { // TODO Auto-generated method stub /* Read from InputStream. If success, set isFileUploaded = true */ System.out.println("Starting upload in a thread"); File outputFile = new File("D:/06c01_output.seg");/* * This will be changed * later */ FileOutputStream fos; ReadableByteChannel readable = Channels.newChannel(inputStream); ByteBuffer buffer = ByteBuffer.allocate(1000000); try { fos = new FileOutputStream(outputFile); while (readable.read(buffer) != -1) { fos.write(buffer.array()); buffer.clear(); } fos.flush(); fos.close(); readable.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("File upload thread completed"); } public boolean isFileUploaded() { return isFileUploaded; } } My queries/doubts : Spawning threads manually from the Servlet makes sense to me logically but scares me coding wise - the container isn't aware of these threads after all(I think so!) The current code is giving an Exception which is quite obvious - the stream is inaccessible as the doPost(...) method returns before the run() method completes : In Controller.doPost(...) In TempModel.uploadSegYFile(...) Returning from TempModel.uploadSegYFile(...) Forwarding to Accepted.jsp Starting upload in a thread Exception in thread "Thread-4" java.lang.NullPointerException at org.apache.coyote.http11.InternalInputBuffer.fill(InternalInputBuffer.java:512) at org.apache.coyote.http11.InternalInputBuffer.fill(InternalInputBuffer.java:497) at org.apache.coyote.http11.InternalInputBuffer$InputStreamInputBuffer.doRead(InternalInputBuffer.java:559) at org.apache.coyote.http11.AbstractInputBuffer.doRead(AbstractInputBuffer.java:324) at org.apache.coyote.Request.doRead(Request.java:422) at org.apache.catalina.connector.InputBuffer.realReadBytes(InputBuffer.java:287) at org.apache.tomcat.util.buf.ByteChunk.substract(ByteChunk.java:407) at org.apache.catalina.connector.InputBuffer.read(InputBuffer.java:310) at org.apache.catalina.connector.CoyoteInputStream.read(CoyoteInputStream.java:202) at java.nio.channels.Channels$ReadableByteChannelImpl.read(Unknown Source) at com.model.FileUploaderRunnable.run(FileUploaderRunnable.java:39) at java.lang.Thread.run(Unknown Source) Keeping in mind the point 1., does the use of Executor framework help me in anyway ? package com.utils; import java.util.concurrent.Future; import java.util.concurrent.ScheduledThreadPoolExecutor; public final class ProcessUtils { /* Ensure that no more than 2 uploads,processing req. are allowed */ private static final ScheduledThreadPoolExecutor threadPoolExec = new ScheduledThreadPoolExecutor( 2); public static <T> Future<T> submitTask(Runnable task, T result) { return threadPoolExec.submit(task, result); } } So how should I ensure that the user doesn't block and the stream remains accessible so that the (uploaded)file can be read from it?

• Can a shell loop unzip all the files in a directory?

  - by helpwithshell

  I've seen loops to unzip all zip files in a directory. However, before I run this, I would rather make sure what I'm about to run will work right: for i in dir; do cd $i; unzip '*.zip'; rm -rf *.zip; cd ..; done Basically I want it to look at the output of "dir" see all the folders, for each directory cd into it, unzip all the zip archives, then remove them, then cd back and do it again until there are no more. Is this something I should do in a single command or should I consider doing this in Perl?

• How to find that 'runas' execution finished?

  - by Radek

  I use ruby 1.9.3p194 (2012-04-20) [i386-mingw32] on Windows7 To do mySQL backup I run runas /savecred /user:yogurt\administrator "cmd.exe /k mysqldump --user=#{dbuser} --password=#{dbpassword} #{dbname} > #{dump}" - mysqldump must be executed as administrator. I do not run my ruby scripts under administrator account. runas starts new cmd.exe and ruby doesn't wait for it to finish. Dump process takes about one minute to finish. After that I zip the dump file and delete it. But I have to make sure that the dump process already finished before I do any other action on that file. Right now I use sleep(60) that works but I wonder if there any better more systematic solution.

• how to controller (start/kill) a background process (server app) in ruby

  - by rubiii

  hey guys, i'm trying to set up a server for integration tests (specs actually) via ruby and can't figure out how to control the process. so, what i'm trying to do is: run a rake task for my gem that executes the integration specs the task needs to first start a server (i use webrick) and then run the specs after executing the specs it should kill the webrick so i'm not left with some unused background process webrick is not a requirement, but it's included in the ruby standard library so being able to use it would be great. hope anyone is able to help! ps. i'm running on linux, so having this work for windows is not my main priority (right now).

• Controlling rsync with Python?

  - by Cheesemold

  I've been wanting to write a python script that would run several instances of rsync in sequence for backing up data to a different computer. At the moment I just have this text file with the commands I use and I've just been copy-pasting them into the terminal, and it seems kinda silly. I want to be able to use python to do this for me. I know very vaguely how to use subprocess.popen, but I have no clue how to get python to interact with rsync directly, like for entering my password for me. Can python do that? Something like: if theProccess.proccessResponse == "Password:" : theProccess.respond(string) Or is the best that I can do is just have it, or even a bash script, just run the rsyncs in sequence and have to type my password in over and over again? Thanks in advance.

• Tomcat thread waiting on and locking the same resource

• ExpandEnvironmentStrings Not Expanding My Variables

  - by Adam Driscoll

  I have a process under the Run key in the registry. It is trying to access an environment variable that I have defined in a previous session. I'm using ExpandEnvironmentStrings to expand the variable within a path. The environment variable is a user profile variable. When I run my process on the command line it does not expand as well. If I call 'set' I can see the variable. Some code... CString strPath = "\\\\server\\%share%" TCHAR cOutputPath[32000]; DWORD result = ExpandEnvironmentStrings((LPSTR)&strPath, (LPSTR)&cOutputPath, _tcslen(strPath) + 1); if ( !result ) { int lastError = GetLastError(); pLog->Log(_T( "Failed to expand environment strings. GetLastError=%d"),1, lastError); } When debugging Output path is exactly the same as Path. No error code is returned. What is goin on?

• How can I write an autostarting dock app for the Mac?

  - by TreeUK

  I have an application I'd like to build that starts when you start the mac and will appear in the dock. I have some experience with Objective-C and iPhone dev but none with Mac dev, I'm also a PC user normally so I'm not au fait with the norms of Mac usage. Any guidance here is appreciated. How do you get an application to autostart? Can you run an app in the tray bar? (with the clock etc in) or do apps only run in the dock?

• Jython: Is there any difference between adding to sys.path vs passing -D?

  - by trinth

  I have a python application that is trying to load some Java libraries (specifically Axis2 web services). When I add the necessary jars in Eclipse via PyDev Project Source Folders, everything seems to work fine. However, I want to be able to do this at run time by adding to sys.path, but then my application doesn't seem to work. In both cases I can load the jars just fine, but something must be different for there to be different results. My question is, is there a difference between adding jars via the sys.path at run time with sys.path.append() versus passing -D to the jython interpreter?

• Log your SQL in Rails application inside unit test

  - by Phuong Nguy?n

  I want to install a logger so that I can dump all executed SQL of my rails application. Problem is, such logger is associated with AbstractAdapter which initialized very soon under test mode, and thus cannot be set by my initializer code. I try to put ActiveRecord::Base.logger = MyCustomLogger.new(STDOUT) in the end of environment.rb like someone advised but it only works when being run in console environment (kicked by script/console), not when run under test mode. I wonder if there is any way to config such logger so that I will sure to be invoked under any environment (test, development, production, console)

• Android: Communication with host computer

  - by dannyn382

  I am looking for ideas as to how all of you can think to solve this issue. I am going to be using an Android Tablet as basically a touch screen input for a project. I need to be able to control servos and solenoids and such, so I will be using a Raspberry Pi to do this. I am looking for ideas on how to get the tablet and the Raspberry Pi to talk. Here are a few that I have though of so far. Use Wifi (which I really do not want to, Ethernet would be okay) to ssh into the Raspberry Pi (with an external library) and run scripts that way from the Android app. Use a com port for Android (maybe Andropod if there hardware becomes available?) and run scripts on the Raspberry Pi. Those are probably two of the "best" ideas that I can think of for now. Can anyone think of any other "better" ideas? Thanks in advance for the help, Dan

• Junit test that creates other tests

  - by Benju

  Normally I would have one junit test that shows up in my integration server of choice as one test that passes or fails (in this case I use teamcity). What I need for this specific test is the ability to loop through a directory structure testing that our data files can all be parsed without throwing an exception. Because we have 30,000+ files that that 1-5 seconds each to parse this test will be run in its own suite. The problem is that I need a way to have one piece of code run as one junit test per file so that if 12 files out of 30,000 files fail I can see which 12 failed not just that one failed, threw a runtimeexception and stopped the test. I realize that this is not a true "unit" test way of doing things but this simulation is very important to make sure that our content providers are kept in check and do not check in invalid files. Any suggestions?

• Blackberry browser problem

  Hi all, I have one site to test, when I run it with my BrowserFieldDemo (in JDE sample)m just display text site, but with the same link, run on Blackberry native browser, it displays properly, and have Zoom in function to zoom. I think the problem here is the size of my site, it's too large. I've tried some different sites and see that the result is same on two browsers, but with this test site, it's unexpected result. Anyone can suggest some solutions for me to fix it? Or explain for me how Blackberry browser can know to resize web page automatically (when it loads the large web page). Thank for any help,

• Passing arguments to a python service

  - by Grim

  Hi, I need some help with a python service. I have a service written in Python. What I need to do is to pass it some arguments. Let me give you an example to explain it a bit better. Lets say I have a service, that does nothing but writes something to a log. I'd like to write the same thing into the log several times, so I use a loop. I would like to pass the counter for the loop when I start the service, but I have no idea how. I start the service with: win32serviceutil.HandleCommandLine(WinService) I'm looking for something like win32serviceutil.HandleCommandLine(WinService,10) I don't really care how its done, as long as I can pass arguments to it. Have been trying to get this to work for the better part of the day with no luck. Also, the service isn't run directly, but is imported and then run from there.

• Debugging (displaying) SQL command sent to the db by SQLAlchemy

  - by morpheous

  I have an ORM class called Person, which wraps around a person table: After setting up the connection to the db etc, I run the ff statement. people = session.query(Person).all() The person table does not contain any data (as yet), so when I print the variable people, I get an empty list. I renamed the table referred to in my ORM class People, to people_foo (which does not exist). I then run the script again. I was surprised that no exception was thrown when attempting to access a table that does not exist. I therefore have the following 2 questions: How may I setup SQLAlchemy so that it propagates db errors back to the script? How may I view (i.e. print) the SQL that is being sent to the db engine If it helps, I am using PostgreSQL as the db
