  • WCF Windows Service - Long operations/Callback to calling module

    - by A9S6
    I have a Windows Service that takes the name of a bunch of files and do operations on them (zip/unzip, updating db etc). The operations can take time depending on size and number of files sent to the service. (1) The module that is sending a request to this service waits until the files are processed. I want to know if there is a way to provide a callback in the service that will notify the calling module when it is finished processing the files. Please note that multiple modules can call the service at a time to process files so the service will need to provide some kind of a TaskId I guess. (2) If a service method is called and is running and another call is made to the same service, then how will that call be processed(I think there is only one thread asociated with the service). I have seen that when the service is taking time in processing a method, the threads associated with the service begin to increase.

  • What should a self-taught programmer with no degree learn/read?

    - by sjbotha
    I am a self-taught programmer and I do do not have any degrees. I started pretty young and I've got about 7 years of actual programming work experience. I believe I'm a pretty good programmer, but I admit that I have not played much with algorithms or delved into any really low-level aspects of programming such as how compilers work. I have worked with other programmers with and without degrees. Some were good and some not; having a degree didn't seem to make any difference as to which pot they fell into. Since then I've come to realize that it does depend on the school where the degree is obtained. Some people suggest that you really should get a degree; that there are things you'll learn in the process that you won't learn in the real world. Of course there is personal growth and discipline learned from completing a task of that magnitude, but let's just concentrate on the technical knowledge. What would I have been taught in a GOOD CS course that would aid me today and what can I read to fill the gap? I've heard the book "Algorithms" mentioned and I plan on reading that. What other books would you recommend? Edit: Clarification on 'actual work experience': Have worked for 2 small companies on teams with fewer than 5 people. About 2 years experience with Perl, Python, PHP, C, C++. About 5 years experience in Java, Applets, RMI, T-SQL, PL/SQL, VB6. 7 years experience in HTML, Javascript, bash, SQL. Most recently in Java designed and helped build an N-tier Java app with web frontend and RMI.

  • Where can a self-teacher learn general good programming habits and conventions?

    - by lucid
    A few mistakes and general childishness in early adulthood have left me in a situation where I work a menial job, with no possibility (in the near future) of attending school. I aspire to one day work in the programming field (gaming specifically), after proving myself on the indie end of things. I've gotten very confident in C++, java, and python, and I find I'm able to solve any problem I want either from previous experience, or from scouring the web for help. The solutions work, and with each attempt they become more readable, maintainable, and extensible. But this is because I'm learning from mistakes and bad programming and design habits I feel I might have avoided with actual schooling. General tips like: "if it's hard to read or getting long, or you're writing it twice, it should be in one or more functions." or "design all your classes before you start coding, so you don't have to rewrite classes later when you discover an unforeseen dependency" Is there a good book or website for learning general good programming practices and design habits? Also, naming and format conventions. I realize sometimes development houses have their own conventions, but things like "Classes in python usually have the first letter of each word capitalized". I'd like to be able to show some source code to a potential employer, and be prepared when for what's expected on a team. Is there some central database of naming and formatting conventions somewhere? Also, feel free to give any thoughts on whether or not the self-teach, garner some indie sales, use them as your resume' route is realistic

  • JSP/Struts2/Hibernate: loop through a self-referencing table.

    - by TBW
    Hello everyone, Let's say we have a self-referencing table called PERSON, with the following columns: ID, PARENT, where PARENT is a foreign key to the ID column of another element in the PERSON table. Of course, many persons can have the same parent. I use Hibernate 3 in lazy fetching mode to deal with the database. Hibernate fetches a person element from the database, which is then put in the ValueStack by the Struts2 action, to be used on the result JSP page. Now the question is : In JSP, how can I do to display all the child (and the child's child, and so on, like a family tree) of this person element? Of course, for the n+1 children I can use the < s:iterator tag over the person.person. I can also nest another < s:iterator tag over person.person.person to get the n+2 children. But what if I want to do this in an automated manner, up to the last n+p child, displaying in the process all the children of all the n+1..n+p elements? I hope I have been clear enough. Thank you all for your time. -- TBW.

  • C# WCF - Failed to invoke the service.

    - by Keith Barrows
    I am getting the following error when trying to use the WCF Test Client to hit my new web service. What is weird is every once in awhile it will execute once then start popping this error. Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.

  • Restarting service from a client computer without rights

    - by Jason
    I have already created the program to restart a SQL database but it only works if the client has the rights. This is going to be done on a local network from a client computer when they can't get a person that has the password on the phone. Any thoughts I'm currently using the servicecontroller to start and stop database. When I don't have the rights I get a access denied error, or This operation might require other privileges. Not sure if impersonation would work since I don't have the userid and password.

  • When is onBind or onCreate called in an android service browser plugin?

    - by anselm
    I have adapted the example plugin of the android source and the browser recognises the plugin without any problem. Here is an extract of AndroidManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> <service android:name="com.domain.plugin.PluginService"> <intent-filter> <action android:name="android.webkit.PLUGIN" /> </intent-filter> </service> </application> <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.webkit.permission.PLUGIN"></uses-permission> The actual Service class looks like so: public class PluginService extends Service { @Override public IBinder onBind(Intent arg0) { Log.d("PluginService", "onBind"); return null; } @Override public void onCreate() { Log.d("PluginService", "onCreate"); // TODO Auto-generated method stub super.onCreate(); AssetInstaller.getInstance(this).installAssets("/data/data/com.domain.plugin"); } } The AssetInstaller code is supposed to extract some files required by the actual plugin into the /data/data/com.domain.plugin directory, however wether onBind nor onCreate are called. But I get lot's of debug trace of the actual libnpplugin.so file I'm using. So the puzzle is when and under what circumstance is the Service bound or created in case of a browser plugin. As things look the service seems to be a dummy service. Having said that, is there another intent that can be executed at installation time probably? The only solution I see right now is installing the needed files from the native plugin code instead. Any ideas? I know this is quite a tricky question ;)

  • Should Service Depend on Many Repositories, or Break Them Up?

    - by Josh Pollard
    I'm using a repository pattern for my data access. So I basically have a repository per table/class. My UI currently uses service classes to actually get things done, and these service classes wrap, and therefore depend on repositories. In many cases my services are only dependent upon one or two repositories, so things aren't too crazy. Unfortunately, one of my forms in the UI expects the user to enter data that will span five different tables. For this form I made a single service class that depends upon five repositories. Then the methods within the service for saving and loading the data call the appropriate methods on all of the corresponding repositories. As you can imagine, the save and load methods in this service are really big. Also, unit testing this service is getting really difficult because I have to setup so many fake repositories. Would it have been a better choice to break this single service apart into a few smaller services? It would put more code at the UI layer, but would make the services smaller and more testable.

  • Android - How to decide wether to run a Service in a separate Process?

    - by pableu
    I am working on an Android application that collects sensor data over the course of multiple hours. For that, we have a Service that collects the Sensor Data (e.g. Acceleration, GPS, ..), does some processing and stores them remotely on a server. Currently, this Service runs in a separate process (using android:service=":background" in the manifest). This complicates the communication between the Activities and the Service, but my predecessors created the Application this way because they thought that separating the Service from the Activities would make it more stable. I would like some more factual reasons for the effort of running a separate process. What are the advantages? Does it really run more stable? Is the Service less likely to be killed by the OS (to free up resources) if it's in a separate process? Our Application uses startForeground() and friends to minimize the chance of getting killed by the OS. The Android docs are not very specific about this, the mostly state that it depends on the Application's purpose ;-) TL;DR What are objective reasons to put a long-running Service in a separate process (in Android)?

  • VMWare server host agent service won't start

    - by Bimo Arioseno
    I'm using VMWare Server 2.0 on Windows Server 2003 R2. Sometimes after restarting the host machine, the VMWare host agent service won't start due to an error. This is the error messages from Event Viewer: [Service control manager] Timeout (30000 milliseconds) waiting for the VMware Host Agent service to connect. [Service control manager] The VMware Host Agent service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. I've set the service to automatically restart after subsequent failure using services.msc (using a 10 min. delay), but it still won't start. Only starting the service manually seems to work. Has anyone experienced this before? What workarounds or fixes are there?

  • SMF restarting service whenever there's output?

    - by Phillip Oldham
    I'm trying to add a custom service to SMF's configuration, which seems successful in that the service starts and there is a log file, but therein lies the problem; the service, on start-up, prints some logging messages to the stderr. It seems that SMF is seeing those messages and, believing them to be errors, restarts the service, giving up after a number of tries and leaving the service off. What would be the best way to manage this service with SMF? The logging is needed for diagnosing problems, and would be problematic to disable. Is it possible to configure this service to only restart if the service exists?

  • tomcat start service NoClassDefFoundError?

    - by mobibob
    I am trying to redeploy my server on a new server with a different DNS and IP address. Therefore, I think my problem is in the configuration to find JAR files. Is there a way to get more detail as to which class is being requested so I can narrow down my problem. Does anyone have any suggested troubleshooting guidance for such problem? BTW - the configuration was working on the original server, and I tried to find all the locations in the files: conf/, worker.properties, server.xml, catalina.policy, web.xml. The jarkarta.log repeats the starting... error initializing ... forever. Very boring, therefore, the problem has to be fundamental. Apparently, the error message is recorded in the log across more than one line and would be this: Error occurred during initialization of VM java/lang/NoClassDefFoundError : java/lang/Object [2012-05-21 18:20:33] [info] Procrun (2.0.4.0) started [2012-05-21 18:20:33] [info] Running Service...

  • "service"-command and environment variables

    - by varesa
    I am trying to start a service that requires a env. variable to be set to certain path. I set this variable in "/etc/profile.d/". However when I start this service using the service command, it doesn't work. man service: service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. So it seems that service is removing my variables. How should I set the variables up to keep them from being removed. Or is that something i should not do. I could start the service manually using the init-scripts, or even hardcode the path into the script, but I'd like to know how to use it with the service command.

  • Why do I get a segmentation fault while redirecting sys.stdout to Tkinter.Text widget in Python?

    - by Brent Nash
    I'm in the process of building a GUI-based application with Python/Tkinter that builds on top of the existing Python bdb module. In this application, I want to silence all stdout/stderr from the console and redirect it to my GUI. To accomplish this purpose, I've written a specialized Tkinter.Text object (code at the end of the post). The basic idea is that when something is written to sys.stdout, it shows up as a line in the "Text" with the color black. If something is written to sys.stderr, it shows up as a line in the "Text" with the color red. As soon as something is written, the Text always scrolls down to view the most recent line. I'm using Python 2.6.1 at the moment. On Mac OS X 10.5, this seems to work great. I have had zero problems with it. On RedHat Enterprise Linux 5, however, I pretty reliably get a segmentation fault during the run of a script. The segmentation fault doesn't always occur in the same place, but it pretty much always occurs. If I comment out the sys.stdout= and sys.stderr= lines from my code, the segmentation faults seem to go away. I'm sure there are other ways around this that I will probably have to resort to, but can anyone see anything I'm doing blatantly wrong here that could be causing these segmentation faults? It's driving me nuts. Thanks! PS - I realize redirecting sys.stderr to the GUI might not be a great idea, but I still get segmentation faults even when I only redirect sys.stdout and not sys.stderr. I also realize that I'm allowing the Text to grow indefinitely at the moment. class ConsoleText(tk.Text): '''A Tkinter Text widget that provides a scrolling display of console stderr and stdout.''' class IORedirector(object): '''A general class for redirecting I/O to this Text widget.''' def __init__(self,text_area): self.text_area = text_area class StdoutRedirector(IORedirector): '''A class for redirecting stdout to this Text widget.''' def write(self,str): self.text_area.write(str,False) class StderrRedirector(IORedirector): '''A class for redirecting stderr to this Text widget.''' def write(self,str): self.text_area.write(str,True) def __init__(self, master=None, cnf={}, **kw): '''See the __init__ for Tkinter.Text for most of this stuff.''' tk.Text.__init__(self, master, cnf, **kw) self.started = False self.write_lock = threading.Lock() self.tag_configure('STDOUT',background='white',foreground='black') self.tag_configure('STDERR',background='white',foreground='red') self.config(state=tk.DISABLED) def start(self): if self.started: return self.started = True self.original_stdout = sys.stdout self.original_stderr = sys.stderr stdout_redirector = ConsoleText.StdoutRedirector(self) stderr_redirector = ConsoleText.StderrRedirector(self) sys.stdout = stdout_redirector sys.stderr = stderr_redirector def stop(self): if not self.started: return self.started = False sys.stdout = self.original_stdout sys.stderr = self.original_stderr def write(self,val,is_stderr=False): #Fun Fact: The way Tkinter Text objects work is that if they're disabled, #you can't write into them AT ALL (via the GUI or programatically).

  • Umbraco Permissions Script - Secure Version

    - by Vizioz Limited
    Back in May I blogged about how to set Permissions for Umbraco using SetACL to set the appropriate directory permissions based on the installation recommendations.Recently I have been working on a site for a client who wanted every security item to be locked down as tightly as possible. And so I modified the script based on the Umbraco security best practices, I thought I'd share it with everyone, if I have missed anything, or if anyone has any suggestions on how to improve this, please let me know :)Please refer to my previous post regarding the SetAcl command line application that you will need.I suggest you save the following into a batch file called: umbPermSecure.batecho offREM Script to setup the Security Permissions for an Umbraco siteREM This script will give your machine Network Service the minimum rights requiredREM for Umbraco to workREM I suggest you update this script to also remove any users who do not need REM access to the web foldersREM **** Pre-requisites ****REM You will need to download - http://setacl.sourceforge.net/REM It is assumed that you have stored SetACL in a directory called, C:\SetACL ifREM not, you will need to modify the script.REM **** Usage ****REM You need to pass in the path for the root of your Umbraco directoryREM E.g. umbPermSecure.bat C:\inetpub\umbracoroot@echo umbPermSecure.bat - Script to set Umbraco File and Directory Permissions@echo based on the Umbraco Security Best Practices Document (13th March 2009)@echo Published by Chris Houston - 19th October 2009@echo http://blog.vizioz.com@echo Adding READ only access SetACL.exe -on "%1" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\web.config" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\bin" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\umbraco" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"@echo Adding READ and EXECUTE access SetACL.exe -on "%1\app_code" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read_ex" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\usercontrols" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read_ex" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"@echo Adding READ, WRITE and MODIFY access SetACL.exe -on "%1\config" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\css" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\data" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\masterpages" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\media" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\python" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\scripts" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\xslt" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"

  • What arguments do I send a function being called by a button in python?

    - by Jared
    I have a UI, in that UI is 4 text fields and 1 int field, then I have a function that calls to another function based on what's inside of the text fields, this function has (self, *args). My function that is being called to takes five arguments and I don't know what to put in it to make it actually work with my UI because python button's send an argument of their own. I have tried self and *args, but it doesn't work. Here is my code, didn't include most of the UI code since it is self explanatory: def crBC(self, IKJoint, FKJoint, bindJoint, xQuan, switch): ''' You should have a controller with an attribute 'ikFkBlend' - The name can be changed after the script executes. Controller should contain an enum - FK/DYN(0), IK(1). Specify the IK joint, then either the dynamic or FK joint, then the bind joint. Then a quantity of joints to pass through and connect. Tested currently on 600 joints (200 x 3), executed in less than a second. Returns nothing. Please open your script editor for details.
