  • Getting the .NET Class associated with a process

    - by John P. Grieb
    As part of a WMI Coupled provider that I'm creating I need to write an instance enumerator. The code I have is below. What I need to do is get the Class instance associated with the process. Any ideas? static public WMIProviderSample GetInstance([ManagementName("ID")] int processId) { try { Process[] processes = Process.GetProcessesByName("WMI Provider Sample"); foreach (Process process in processes) { if (process.Id == processId) { // Need to convert the process to an instance of WMIProviderSampel } } return null; } catch (ArgumentException) { return null; } }

  • source control when starting up a new project

    - by jaras
    when starting with a project and using source control i find it hard to separate the things people are working on so they don't either write duplicate code or think it should be named one thing and so on. this problem diminishes over time because the general foundation is in place and it's easier to separate the tasks so they don't overlap as much how do you manage working with source control in the beginning phase? EDIT: I can see that it don't really have anything to do with source control, but it gets more apparent when you have source control too. so the question becomes more along the lines of "how do you manage to separate the tasks so they don't overlap too much. I think it's really hard and i haven't really seen much about how to do it.

  • Error running celeryd

    - by Eric Palakovich Carr
    I'm posting this question (and answer) so if anybody else has this problem in the future, you'll be able to google it. If you are trying to run celeryd in Django like so: python manage.py celeryd You can receive the following error immediately after it has started: celery@eric-desktop-dev has started. Traceback (most recent call last): File "manage.py", line 11, in <module> execute_manager(settings) <... snip ...> File "/usr/local/lib/python2.6/dist-packages/amqplib-0.6.1-py2.6.egg/amqplib/client_0_8/connection.py", line 134, in __init__ self._x_start_ok(d, login_method, login_response, locale) File "/usr/local/lib/python2.6/dist-packages/amqplib-0.6.1-py2.6.egg/amqplib/client_0_8/connection.py", line 704, in _x_start_ok args.write_longstr(response) File "/usr/local/lib/python2.6/dist-packages/amqplib-0.6.1-py2.6.egg/amqplib/client_0_8/serialization.py", line 352, in write_longstr self.write_long(len(s)) TypeError: object of type 'NoneType' has no len() A rather cryptic error message, with no real clue as to where to go to fix the problem. See below for the answer so you don't waste a bunch of time on this error like I did today :)

  • SQL 2008 Encryption Scan

    - by Mike K.
    We recently upgraded a database server from SQL 2005 to SQL 2008 64 bit. CPU utilization is oftentimes running at 100% on all four processors now (this never happended on the SQL 2005 server). When I run sp_lock I see a number of processes waiting on a resource called [ENCRYPTION_SCAN]. I am not using any SQL 2008 encryption features. Does anyone know why I would have tasks waiting on this resource? It appears that whenever I have four processes waiting on this resource, CPU hits 100% on all four processors.

  • See if any application has a DLL from the GAC loaded

    - by rwmnau
    I'm trying to deploy new copies of my DLL to the GAC on remote servers, but I need to identify if any processes currently running have a loaded copy of the DLL I'm replacing - I'd like to restart them, or at least tell the user. For example, Biztalk seems to load the DLLs it needs the first time they're used, and then replacing them keeps the old copy in memory until the Host Instances are restarted - something I could easily do as part of my deployment. Is there a way to tell using .NET which processes have loaded a particular DLL from the GAC? UPDATE: Some further investigation shows that both Process Explorer has this functionality, and another Sysinternals tool, ListDLL, does exactly what I want to be able to do. I'd like to know how they do it, since I'd love to replicate this functionality in my application without having to include and screen-scrape ListDLL (if that's even allowed inside the license).

  • Mysql adapter for Zend_Translate

    - by Peter
    Hi everybody, I'm currently in the planning phase of a rather large project that I'll develop in the Zend Framework. One of the problems I'm facing is that the customers will want to translate not only the content but also the interface. I'm currently using gettext and poedit to manage my language files but this is not an option for the customer as they, for one, want have FTP access to the site. Hence, I'm thinking of a mysql back end with an interface in the front end for the customer to manage his own translations of the interface. There is however still no mysql adapater for Zend_Translate. So, does anybody now of an adapter script for Zend_Translate so it can work with a mysql table? Or any arguments against using mysql and possible other solutions for this problem?

  • Job queue manager with RPC interface

    - by admr
    I need a job queue manager that I can control over the Internet. It should be able to execute and stop processes, check on their status (ideally notice and execute some code when a process exits), respond to commands and also be able to report back to a server. Background: I have a GWT application that allows to create jobs to execute on a cloud instance (currently EC2). I want to push a "job packet" (data for a process to operate on etc) to S3, start a Linux EC2 instance (or use one that's already running), and tell a job manager on the instance to execute that job (possibly parallel to other jobs). It should then pull the "job packet" from S3, run a process that operates on that data and report back to the server that is running the server part of my GWT application with some information (e.g. exit code, stdout, stderr). If I have to write e.g. stdour/err to a file from the process and read that file, that's OK too. I would really like the manager to be "close" to the processes it runs, meaning I want to avoid using something like Runtime.exec from the JDK. It seems like I would have to do that if I used Quartz for example. I'm fine with the calls in both directions being asynchronous. I'm fine with any reasonable technology for the calls as long as I can easily build an interface for that in my GWT server side (e.g. HTTP requests to a servlet over SSL would be nice and trivial). The job manager does not need to have a very sophisticated queueing system. Running several processes either sequentially or in parallel should be fine. Determining how much compute time a process received during its lifetime would be nice (AFAIK, this might be challenging). I did not yet find any existing software that does this, including http://java-source.net/open-source/job-schedulers. I suspect I might have to build an RPC interface (with authentication etc, of course) around a job manager; maybe use something like Apache Commons Exec. In that case, I would prefer Java or Python for the job manager part. I would be happy to hear suggestions for either the former or latter scenario!

  • Eclipse Basic Web Development?

    - by Sean Ochoa
    I want to start doing web development with Eclipse. Not Java, tomcat, axis2, or anything else anymore complicated than basic XHTML / JS / CSS development, at this time. Problem 1: I realize that it can edit those files, but its trying to manage my HTML docs as part of "my workspace", and all I want it to do is manage the files as part of my local www server HTdocs directory. Problem 2: I would like to edit WYSIWYG-style, if possible. I tried installing a plug-in for that, but I wasn't able to get w4 toolkit to function properly. This would really help me to speed up development, I think. Follow-up: I've installed WTP and its dependencies (except for the tests portion, which had install problems due to dependencies that were seemingly irreconcilable).

  • Keeping a database structure up to date in a project where code is on subversion?

    - by Bruno De Barros
    I have been working with Subversion for a while now, and it's been incredible for the management of my projects, and even to help managing the deployment to several different servers, but there is just the one thing that still annoys me. Whenever I make any changes to the database structure, I need to update every server manually, I have to keep track of any changes I made, and because some of my servers run branches of the project (modifications that are still being worked on, or were made for different purposes), it's a bit awkward. Until now, I've been using a "database.sql" file, which is a dump of the database structure for a specific revision. But it just seems like such a bad way to manage this. And I was wondering, how does everyone else manage their MySQL databases when they're working on a project and using Subversion?

  • Ad/Banner Management/Rotation for Ruby on Rails?

    - by David N. Welton
    Hi, I have a niche site that I'd like to sell banners for directly, rather than going through adsense. I need a system to manage the whole process: displaying ads and an administrative interface to manage them. It doesn't have to be anything terribly fancy, although open source is greatly preferred so that I can grow the system as needs be. Since the site itself is in Rails, I would prefer something for that environment. Googling turns up bunches of them in PHP, but the results are a bit polluted and I didn't have any luck finding one that was done in/for Rails. If I don't find one, I suppose I'll see what I can do to hack together something and release it myself under an open license. Another possibility is this: http://www.google.com/admanager - anyone have anything to say about it? Is it right for someone just selling a few ads for a not-so-big site? Thanks, Dave

  • Killing Mysql prcoesses staying in sleep command.

    - by Shino88
    Hey I am connecting a MYSQL database through hibernate and i seem to have processes that are not being killed after they are finished in the session. I have called flush and close on each session but when i check the server the last processes are still there with a sleep command. This is a new problem which i am having and was not the case yesterday. Is there any way i can ensure the killng of theses processes when i am done with a session. Below is an example of one of my classes. public JSONObject check() { //creates a new session needed to add elements to a database Session session = null; //holds the result of the check in the database JSONObject check = new JSONObject(); try{ //creates a new session needed to add elements to a database SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); session = sessionFactory.openSession(); if (justusername){ //query created to select a username from user table String hquery = "Select username from User user Where username = ? "; //query created Query query = session.createQuery(hquery); //sets the username of the query the values JSONObject contents query.setString(0, username); // executes query and adds username string variable String user = (String) query.uniqueResult(); //checks to see if result is found (null if not found) if (user == null) { //adds false to Jobject if not found check.put("indatabase", "false"); } else { check.put("indatabase", "true"); } //adds check to Jobject to say just to check username check.put("justusername", true); } else { //query created to select a username and password from user table String hquery = "Select username from User user Where username = :user and password = :pass "; Query query = session.createQuery(hquery); query.setString("user", username); query.setString("pass", password); String user = (String) query.uniqueResult(); if(user ==null) { check.put("indatabase", false); } else { check.put("indatabase", true); } check.put("justusername", false); } }catch(Exception e){ System.out.println(e.getMessage()); //logg.log(Level.WARNING, " Exception", e.getMessage()); }finally{ // Actual contact insertion will happen at this step session.flush(); session.close(); } //returns Jobject return check; }

  • Version control for Adobe Flash projects

    - by Guss
    I'm working with a very complex Flash project which is part of a full range of services that we deploy for the use of our clients. For most of our software sources (Java, PHP, Javascript, HTML and a some supporting scripts in other languages) we use subversion for version control and management, so we do the same for our Flash projects, even though we gain little benefits from version controlling that (except being able revert to previous versions) as FLA files are stored as just binaries which we cannot get meaningful diffs from. We're putting as much code as we can into AS files which we can properly manage using subversion, but due to the requirements of our architecture and our deployment strategy (both we cannot change because of our clients needs), we still maintain a large collection of FLA files that we need to manage. I've looked at Adobe Version Cue and while I do not really understand what it does in terms of version control, will moving our Flash projects to hosting on Version Cue will give me better control then I currently get from Subversion? Also - if people can share their experience and suggestions regarding version control of Flash projects, it will be very helpful.

  • Mercurial Messing Up csproj Files?

    - by alphadogg
    I am using Hg to manage and merge code with three other developers involved in a VS2008 project. We do have an .hgignore file that ignores a fair number of files not necessary to track, such as *.pdb, *.obj, etc. However, we do track .csproj files. Periodically, it would seem that files go missing after a merge. We would get build issues, and have to relocate files which were in the project folders, but not in the csproj file. Eventually, I noted during a merge conflict that sometimes Hg seems to merge incorrectly. Here's a screenshot below. The actual conflict that requires manual intervention is lower in the file. But in this section, hg incorrectly replaces DirectoryTasks.cs with a new, different file called ReportTasks.cs, when in fact, both should be added. How do people manage to avoid this?

  • Large Scale VHDL techniques

    - by oxinabox.ucc.asn.au
    I'm thinking about implimenting a 16 bit CPU in VHDL. A simplish CPU. ADD, MULS, NEG, BitShift, JUMP, Relitive Jump, BREQ, Relitive BREQ, i don't know somethign along these lines Probably all only working with 16bit operands. I might even cut it down and use only a single operand and a accumulator. With Some status regitsters, Carry, Zero, Neg (unless i use a Accumlator), I know how to design all the parts from logic gates, and plan to build them up from first priciples, So for my ALU I'll need to 'build' a ADDer, proably a Carry Look ahead, group adder, this adder it self is make up oa a couple of parts, wich are themselves made up of a couple of parts. Anyway, my problem is not the CPU design, or the VHDL (i know the language, more or less). It's how i should keep things organised. How should I use packages, How should I name my processes and port maps? (i've never seen the benifit of naming the port maps, or processes)

  • Obtain Update Table Lock at start of Stored Procedure in SQL Server

    - by Jim Hurne
    I'm writing a SQL Server stored procedure in which I want to lock a table for update before executing the body of the stored procedure. I don't want to prevent other processes from reading the table, but I do want to prevent other processes updating the table. Here is my first attempt: CREATE PROCEDURE someProcedure BEGIN SET TRANSACTION ISOLATION LEVEL READ COMITTED BEGIN TRANSANCTION SELECT COUNT(*) FROM TheTable WITH (UPDLOCK, TABLOCK) -- Pause procedure so that we can view the locks with sp_lock WAITFOR DELAY '00:15' -- Do stuff COMMIT END When I execute the stored procedure, and invoke sp_lock, I see that the table is indeed locked. However, it's locked with an Exclusive lock instead of an update lock: spid | dbid | ObjId | IndId | Type | Resource | Mode | Status ------------------------------------------------------------------ 63 | 10 | 233208031 | 0 | TAB | | X | GRANT How can I get an update (U) lock instead?

  • Distinct rand() sequences yielding the same results in an expression

    - by suszterpatt
    Ok, this is a really weird one. I have an MPI program, where each process has to generate random numbers in a fixed range (the range is read from file). What happens is that even though I seed each process with a different value, and the numbers generated by rand() are different in each process, the expression to generate the random numbers still yields the same sequence between them. Here's all relevant code: // 'rank' will be unique for each process int rank; MPI_Comm_rank(MPI_COMM_WORLD, &rank); // seed the RNG with a different value for each process srand(time(NULL) + rank); // print some random numbers to see if we get a unique sequence in each process // 'log' is a uniquely named file, each process has its own log << rand() << " " << rand() << " " << rand() << std::endl; // do boring deterministic stuff while (true) { // waitTimeMin and waitTimeMax are integers, Max is always greater than Min waitSecs = waitTimeMin + rand() % (waitTimeMax - waitTimeMin); log << "waiting " << waitSecs << " seconds" << std::endl; sleep(waitSecs); // do more boring deterministic stuff } Here's the output of each process, with 3 processes generating numbers in the range [1,9]. process 1: 15190 28284 3149 waiting 6 seconds waiting 8 seconds waiting 9 seconds waiting 4 seconds process 2: 286 6264 3153 waiting 6 seconds waiting 8 seconds waiting 9 seconds waiting 4 seconds process 3: 18151 17013 3156 waiting 6 seconds waiting 8 seconds waiting 9 seconds waiting 4 seconds So while rand() clearly generates different numbers, the expression to calculate waitSecs still evaluates to the same sequence on all processes. What's even weirder: if I run the program with the same parameteres again, only the first 3 random numbers will change, the rest of the "random" sequence will be exactly the same in each run! Changing the range of numbers will obviously produce a different result from this one, but the same parameters always yield the same sequence, between processes and between executions: except for the first 3 numbers. Just what the hell is going on here?

  • Redirect application's graphical output in Windows Vista/7 (with DWM)

    - by puri
    I want to create a desktop manager that takes informations of all running applications including states and screenshots to display and manipulate them in my virtual space (probably in 3D). It can be considered as another layer of abstraction on top of Windows itself. Because many native Windows Vista/7 features like Flip 3D and Live Thumbnails are able to show each window's activities in real-time e.g. video keeps playing in taskbar's thumbnail, I think DWM allows an application to redirect its output to somewhere else or some special processes are able to collect other applications' graphical outputs (maybe of child processes only). Has Microsoft released a set of public APIs to do so? If not, is it technically possible? And is it easier if I limit my scope to just .NET applications with WPF?

  • simple process rollback question

    - by OckhamsRazor
    hi folks! while revising for an exam, i came across this simple question asking about rollbacks in processes. i understand how rollbacks occur, but i need some validation on my answer. The question: my confusion results from the fact that there is interprocess communication between the processes. does that change anything in terms of where to rollback? my answer would be R13, R23, R32 and R43. any help is greatly appreciated! thanks!

  • PHP Sessions - Locking and Sharing questions

    - by Nuno Peralta
    Hi, I would like to know if it is possible to read $_SESSION attributes without locking it. Currently, session_start() locks SESSION, that means other PHP processes will wait until it is unlocked. But, some processes just want to get some $_SESSION variables, not to write on them. Is that possible to implement some function like session_get(string $id) which doesn't lock SESSION? Also, it is possible to share SESSIONs between browsers, once the user is logged in the same account, for example, using session_id('shared_vars_of_'.$userid). But, is that secure? Is this discouraged? Thanks, Nuno

  • Creating managed file transfer software in java

    - by Shekhar
    Hello, I have been asked to do some POC on how we can provide a software solution which will be able to manage files. Manage files means it will be able to move files from source to destination servers. The client gave us 4 page document detailing what sort of software they are looking for. They dont want to use existing commercial softwares. They want to build their own customizable software. Has anybody worked on this type of project? Please provide your inputs on how should i approach this project. The software should be platform independent and should be built in java.

Why would that happen? Why it did not generate 5 processes and exit? Why do I need the if statement?

  • Django "Error: cannot import name escape" on windows

    - by Sam
    I cannot run the dev server because of this error ("Error: cannot import name escape"). I assume its because of modifications I've done to the project, but i have no idea how to find where the error is originating from to fix it. I don't import anything called escape anywhere. Update Using django-admin.py rather than the projects manage.py, don't know why... Update 2 Now manage.py is working. This may be because I had a file called email.py which was trying to import email.mime.text (ie trying to import itself) renaming to sendemail.py solved this problem.

  • iPhone StoreKit development: Can't create a test user?

    - by Cruinh
    I'm trying to get up to speed on how to develop an in-app store using the new 3.0 SDK... but I'm a bit stuck in that I don't seem to be able to create a test account. The iTunes Connect FAQ states "To create test users for your sandbox environment, go to the Manage Users section of iTunes Connect and select In App Purchase Test User. Your test users will not have iTunes Connect access. They will just have access to the sandbox environment." ...but when I go to that Manage Users section, there's no mention of any sort of "In App Purschase Test User" or how to make one. Did I miss doing something to enable that? There is another section of that same FAQ that seems to suggest I need to have a paid app in the store first? Is that the reason I can't even use the test environment?
