  • How can I seperate my TransactionScope so they don't interfere with each other?

    - by shenku
    I have some business logic that executes within a simple TransactionScope. using (var scope = new TransactionScope()) { // does some logic. // then some more... scope.Complete(); } During execution an ado exception ocurres and the transaction is on it's way to being disposed. In the mean time the exception is captured further upstream, and I try to log it to my database, via another connection. At this point I get another error saying The operation is not valid for the state of the transaction. Eeek! Now I can see I am able to use IsolationLevel, to change the way my transactions interact, but is this the right thing to do? And which should I use?

  • How do I validate that my the openid.op_endpoint when a request is completed.

    - by Sam Saffron
    I have an Open ID based authentication system on my site. Occasionally users will have an account registered under [email protected] and they will attempt to login using the google open id provider https://www.google.com/accounts/o8/id, in this case I would like to automatically associate the account and log them in. When the process is done I get a payload from somewhere claiming that openid.op_endpoint=https://www.google.com/accounts/o8/id. My question: Can I trust openid.op_endpoint to be correct? Can this be spoofed somehow by a malicious openid provider? For illustration, lets say someone types in http://evil.org as their openid provider, can I somehow end up getting a request back that claims openid.op_endpoint is google? Do I need to store extra information against the nonce to validate? The spec is kind of tricky to understand

  • Backgroundworker haults in between

    - by Dharmendra
    I am starting a process lets say abc.exe in a background worker. In the begining everything works fine but in between the newly created process i.e. abc.exe haults.

  • Is it possible to get Logged in user Non Restricted token from a service on Vista?

    - by coolcake
    Hello All, I need to create a process with integrity level high, so that it can do all the administrative tasks. But the created process should run in the current logged in desktop i.e. it should not run in session 0. By default only administrators will log on to the console. The service should launch the process, as service is running in session 0 and system account. Can it any how get the non restricted token and use it in CreateProcessAsUser, so that the process created does have integrity level of high or system. Is it possible? One more thing is i should get the non restricted token with out prompting for user name or password of the logged in user. Thanks

  • Can I change the datsource of report model at runtime

    - by Manab De
    I've some adhoc reports developed on some report models which are published on Report Server (we're using SSRS 2008). Everything is running well. Now in our production environment we've near about forty (40) customers who have their own database (each have the same table structures and other database objects). Now the challenge is whenever a customer will log into the report server using windows authentication and trying to view those reports we need to get the SQL data from the proper database only. Reports are designed using the report model and each model has a valid data source which is connected to particular database. We can create forty separate data sources each will be connected to specific database. My question is, is there any way through which we can change the report model data source name dynamically or during runtime based on the customer name so that during execution of the report, SSRS would fetch the data from the correct database but not from any other database. Please help me.

  • Rails + RSpec problem

    - by FancyDancy
    I have just installed Rspec and Rspec-rails. When i try to run the test, it says: rake aborted! Command /opt/local/bin/ruby -I"lib" "/opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/bin/spec" "spec/controllers/free_controller_spec.rb" --options "/Volumes/Trash/dev/app/trunk/spec/spec.opts" failed Full log here: http://pastie.org/939211 However, my second "test" application with sqlite works with it. I think the problem is in my DB. My ruby version is 1.8.7, i use mysql as database. My files: specs/spec_helper.rb config/environment.rb config/environments/test.rb List of my gems My test is just: require 'spec_helper' describe FreeController do it "should respond with success" do get 'index' response.should be_success end end I really can't understand the error, so i don't know how to fix it.. Additional question: should i use a fixtures and ActiveRecord, if i going to use Machinist for creating test data? What should i do to disable them?

  • Is this an injection attempt or a normal request?

    - by CheeseConQueso
    In cPanel's Analog Stats statistics module, I've noticed countless requests to connect to the following example: /?x=19&y=15 The numbers are random, but its always setting x and y variables. Another category of mysterious requests: /?id=http://nic.bupt.edu.cn/media/j1.txt?? There are other attempts at injections in the request log that have straight sql written into them as well. Example: /jobs/jobinfo.php?id=-999.9 UNION ALL SELECT 1,(SELECT concat(0x7e,0x27,count(table_name),0x27,0x7e) FROM information_schema.tables WHERE table_schema=0x73636363726F6F745F7075626C6963),3,4,5,6,7,8,9,10,11,12,13-- It looks like they are all reaching a 404, but I'm still wondering about the intent behind these. I know this is vague, but maybe someone knows that this is normal while using cPanel & phpMyAdmin services. Also, there was a search box installed on the site which could be the reason. Any suggestions as to what all these are?

  • Prepared statement initialized tiwice and closed once

    - by sonam
    Hi, I want to know that if a PreparedStatement object is initialized twice the way shown in code snippet below and closed only once in finally block, will it fail to close? I am not getting any error in this code but will it be a better idea to use 2 different preparedStatements instead of one. I think it fails to close the preparedStatement at #1. Connection conn = null; PreparedStatement ps = null; try { conn = getConnection(); ps = conn.prepareStatement(QueryUtil.UPDATE_POLICY_DETAILS); // #1 ps.setInt(1, iCancellationPolicyId); ps.executeUpdate(); //some code here ps = conn.prepareStatement(QueryUtil.UPDATE_POLICY_CHARGES); // #2 ps.setInt(1, iCancellationPolicyId); ps.executeUpdate(); //some code here } catch (SQLException sqlExp) { sqlExp.printStackTrace(); LOG.fatal(sqlExp); } finally { conn.close(); ps.close(); }

  • How Proxy server works with tcp/http connections?

    - by Vivek
    Since I am a beginner in the world of internet/networking, I always mess up with these kinds of doubts in my head while programming ;) .. My doubts are, While working behind a proxy, how my requests and responses work? Means my request headers and data will first reach to Proxy server- then proxy server sends it(same headers and data) to corresponding server. And server responses to it with a response header and body to the proxy server-then proxy server sends it to my computer. Wright? While using websockets we are upgrading our http connection to tcp. At this time what is happening @ Proxy server? Does the proxyserver also upgrades its connection to plain TCP? After opening such TCP connections, does the proxy server able to track/log those socket messsages? And most importantly, Is the proxy server transparent or acting like an original server infront of a client? Thanks for any answers or helpful links in advance.

  • jQuery Running a function in a context and adding to a variable

    - by Mark
    For this question I'm going to give a simplified example of what I want to do, and the function I want to learn to write. var collection = ''; <div id='container'> <span>1</span> <span>2</span> <span>3</span> </div> What I want to do this, for every span in the div, take its text, add it to the collection. So ideally it would look like: $('#container').addtoCollection(collection); The method would be something like: $(this).find('span').each(function () { collection = collection + $(this).text(); }). Where the first this would equal #container. So in the end you can do: console.log(collection); and get: 123 How do I write the function that does this? Thanks!

  • How do detect that transaction has already been started?

    - by xelurg
    I am using Zend_Db to insert some data inside a transaction. My function starts a transaction and then calls another method that also attempts to start a transaction and of course fails(I am using MySQL5). So, the question is - how do I detect that transaction has already been started? Here is a sample bit of code: try { Zend_Registry::get('database')->beginTransaction(); $totals = self::calculateTotals($Cart); $PaymentInstrument = new PaymentInstrument; $PaymentInstrument->create(); $PaymentInstrument->validate(); $PaymentInstrument->save(); Zend_Registry::get('database')->commit(); return true; } catch(Zend_Exception $e) { Bootstrap::$Log->err($e->getMessage()); Zend_Registry::get('database')->rollBack(); return false; } Inside PaymentInstrument::create there is another beginTransaction statement that produces the exception that says that transaction has already been started.

  • .net exception pool

    - by javier
    I want to create a mecanism in a large .net application to handle all the exceptions in the application, and to save the error messages (in db or log file) so these errors can be fixed, and so we are aware of the problems in the application. Does anyone know a good way of creating a library to handle and process all the exceptions?. Are there any tools around that can simplify my task. What aproach would you suggest me to take.... If you previously implemented something similar to what I want to do, I do want to heard from you Thanks all

  • Backdoor Strategy- opinion needed.

    - by the Hampster
    I'm creating an application to track publications and grants for a university. Professors will need to put they CV into the system when it is up and running. Yeah, right. The person in charge is planning on hiring someone to input all of the information, but my questions is how? The strategy I'm thinking of is to install a backdoor. The lucky undergrad can log in as any professor using the backdoor. Once all the data is removed, the backdoor can be removed. Doing so would probably be as simple as editing out a comment in the config file. The IT guys would still have access, but since they control the machines, they would have access anyway. Are there any flaws to this strategy?

  • Error in vb.net windows service when connecting to SQL

    - by Clint
    I've installed a vb.net windows service on a Windows 2008 machine, that is attempting to connect to SQL 2005. The service starts succesfully, but can't see the database. The event log has the following entry. The description for Event ID 0 from source SU4.ESMR.DAL.Job.FillPriorityJobByType(oJobDS, TypeID: 3 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. This was tested locally on both XP and 2008. All environments are 32 bit.

  • Recieveing "EXC_BAD_ACCESS" before any UI elements load (on device only)

    - by morgancodes
    Everything works fine on the simulator, but I gete EXC_BAD_ACCESS when I try to load my app on the device. I've put in a bunch of NSLogs to try and catch where it happens, but the log statements are never reached. Also, the UI doesn't load. So, seems the problem is happening before any of my code is reached. I tried a clean build, no luck. Also tried building and installing a different app, which works fine. So, looks like there's something wrong with my app, but it's something that happens before any of my code gets called. So, any ideas?

  • Using locks inside a loop

    - by Xaqron
    // Member Variable private readonly object _syncLock = new object(); // Now inside a static method foreach (var lazyObject in plugins) { if ((string)lazyObject.Metadata["key"] = "something") { lock (_syncLock) { if (!lazyObject.IsValueCreated) lazyObject.value.DoSomething(); } return lazyObject.value; } } Here I need synchronized access per loop. There are many threads iterating this loop and based on the key they are looking for, a lazy instance is created and returned. lazyObject should not be created more that one time. Although Lazy class is for doing so and despite of the used lock, under high threading I have more than one instance created (I track this with a Interlocked.Increment on a volatile shared int and log it somewhere). The problem is I don't have access to definition of Lazy and MEF defines how the Lazy class create objects. My questions: 1) Why the lock doesn't work ? 2) Should I use an array of locks instead of one lock for performance improvement ?

  • write cache and write sequence order

    - by excanoe
    ok, here i have some weird question: let say we have some binary file (.log), and sequence of write operations, for example log1, log2, log3 and each has some block size n (raw data). question: can I be sure that log1,log2 and log3 sequences can be written in the correct order in ONE file, even if i have few cache levels (disk hardware and os level)? update very interested in what will be with records order (not with records) if we have software or hardware failure (reboot or another reason). update there can be some percent of write failures, but main question is: will write order stay correct?
