  • Using a Cross Thread Boolean to Abort Thread

    - by Jon
    Possible Duplicate: Can a C# thread really cache a value and ignore changes to that value on other threads? Lets say we have this code: bool KeepGoing = true; DataInThread = new Thread(new ThreadStart(DataInThreadMethod)); DataInThread.Start(); //bla bla time goes on KeepGoing = false; private void DataInThreadMethod() { while (KeepGoing) { //Do stuff } } } Now the idea is that using the boolean is a safe way to terminate the thread however because that boolean exists on the calling thread does that cause any issue? That boolean is only used on the calling thread to stop the thread so its not like its being used elsewhere

  • XCOPY-deploying Microsoft Sync Framework in a no admin rights scenario (i.e. ClickOnce install)

    - by Mike Bouck
    I'm currently designing a smart client app (WPF) which needs to operate in an "occasionally disconnected" mode. For the offline scenario, I'm looking at using: Disconnected Service Agent Application Block (from the Smart Client Software Factory) Microsoft Sync Framework I should mention that I want my smart client app to be XCOPY-deployable, auto-updating, and installable without administrative privledges -- basically a ClickOnce-deployed app. From what I can tell this means the Microsoft Sync Framework is out because it has some COM in it's implementation that needs to get registered on the client which requires admin rights. Is it possible to XCOPY deploy and run MSF from a ClickOnce app? Any other ideas for data synchronization?

    - by CoffeeCode

  • Validation not bubbling up to my other models.

    - by DJTripleThreat
    Ok, I have a relationship between People, Users and Employees such that All Employees are Users and all Users are People. Person is an abstract class that User is derived from and Employee is derived from that. Now... I have an EmployeesController class and the create method looks like this: def create @employee = Employee.new(params[:employee]) @employee.user = User.new(params[:user]) @employee.user.person = Person.new(params[:person]) respond_to do |format| if @employee.save flash[:notice] = 'Employee was successfully created.' format.html { redirect_to(@employee) } format.xml { render :xml => @employee, :status => :created, :location => @employee } else format.html { render :action => "new" } format.xml { render :xml => @employee.errors, :status => :unprocessable_entity } end end end As you can see, when I'm using the :polymorphic => true clause, the way you access the super class is by doing something like @derived_class_variable.super_class_variable.super_super_etc. The Person class has a validates_presence_of :first_name and when it is satisfied, on my form, everything is OK. However, if I leave out the first name, it won't prevent the employee from being saved. What happens is that the employee record is saved but the person record isn't (because of the validation). How can I get the validation errors to show up in the flash object?

  • gcalFeed is not a function?

    - by fossildesigns
    I set up a calendar for the department at the university where I work (http://www.uwsp.edu/conted/calendar/default.aspx), this works just great. I then turned around and uploaded all the jquery files and fullcalendar.css to my development server (http://fossilfoundry.com/test/test.htm). When the page loads I get a JavaScript Error stating that $.fullCalendar.gcalFeed is not a function. All the files are local to the .htm page. I've checked everything I can think of. Any ideas why this won't run?

  • Error openin microsoft.com with google chrome

    - by Ilnur
    Hi! I need help with my browsers. In my OS (windows 7 basic) installed 2 browsers: IE 8 and Google Chrome. When I trying to open pages, which associated with microsoft.com (like ms live and others), my browser crashes. IE 8 crashes too. But Opera (I've installed it later) works fine with that pages. P.S. I tried to search the trojan software and viruses. But my PC is clean.

  • Libraries/Solutions for using XSL to create interactive web forms from XML

    - by Brabster
    This seems like a pretty straightforward thing to do, but I can't find anything off the open-source shelf. Is there a solution already out there that does the following: can be configured with an arbitrary XSL stylesheet generates a web form based on an arbitrary XML document and the XSL creates edit functionality in appropriate places in the rendered form updates the local representation of the XML document provides capabilities to view, save the new XML document Ideally, one that plugs into a Java web application. Even better if it can generate the XSL based on schema documents - but that might not be feasible, not really thought it through. For context, I'm thinking things like pleasant-for-humans editing of Maven POMs, ANT build.xml, etc. Cheers,

  • SQL Reporting Services Daylight saving time query (pt 2)

    - by ross-starkey
    I posted a question a couple of days ago (SQL Reporting Services Daylight saving time query) which was I received an answer for (thanks very much) but did not elaborate on the whole problem I am experiencing. Not only did I require the returned date time format to account for day light saving but I also need the search parameter @StartDate to allow for DST. Currently if I key in a scheduled start time of 31/03/2010 11:00 and because the SQL DB has already taken the hours difference into consideration I get no results back. If I key in 31/03/2010 10:00 then the correct details are returned. Is there away using T-SQL or the like to get the search parameter to pass the adjusted time to the DB?

  • if cookies are disabled, does asp.net store the cookie as a session cookie instead or not?

    - by Erx_VB.NExT.Coder
    basically, if cookeis are disabled on the client, im wondering if this... dim newCookie = New HttpCookie("cookieName", "cookieValue") newCookie.Expires = DateTime.Now.AddDays(1) response.cookies.add(newCookie) notice i set a date, so it should be stored on disk, if cookies are disabled does asp.net automatically store this cookie as a session cookie (which is a cookie that lasts in browser memory until the user closes the browser, if i am not mistaken).... OR does asp.net not add the cookie at all (anywhere) in which case i would have to re-add the cookie to the collection without the date (which stores as a session cookie)... of course, this would require me doing the addition of a cookie twice... perhaps the second time unnecessarily if it is being stored in browsers memory anyway... im just trying not to store it twice as it's just bad code!! any ideas if i need to write another line or not? (which would be)... response.cookies.add(New HttpCookie("cookieName", "cookieValue") ' session cookie in client browser memory thanks guys

I have tried a lot to filter this but unsuccessful for me.

  • Why isn't the reference counter in boost::shared_ptr volatile?

    - by Johann Gerell
    In the boost::shared_ptr destructor, this is done: if(--*pn == 0) { boost::checked_delete(px); delete pn; } where pn is a pointer to the reference counter, which is typedefed as shared_ptr::count_type -> detail::atomic_count -> long I would have expected the long to be volatile long, given threaded usage and the non-atomic 0-check-and-deletion in the shared_ptr destructor above. Why isn't it volatile?
