  • Autofac: Reference from a SingleInstance'd type to a HttpRequestScoped

    - by Michael Wagner
    I've got an application where a shared object needs a reference to a per-request object. Shared: Engine | Per Req: IExtensions() | Request If i try to inject the IExtensions directly into the constructor of Engine, even as Lazy(Of IExtension), I get a "No scope matching [Request] is visible from the scope in which the instance was requested." exception when it tries to instantiate each IExtension. How can I create a HttpRequestScoped instance and then inject it into a shared instance? Would it be considered good practice to set it in the Request's factory (and therefore inject Engine into RequestFactory)?

  • Where is the taglib definition of PrimeFaces 4?

    - by Michael Wölm
    I am looking around how to define custom components in JSF. According to the Java EE tutorial, any custom component needs to be described in a taglib. When I take a look into the PrimeFaces source, I cannot find any taglib file or any hint where the namespace is bound and the available components are defined. I am adding primefaces jar to my dependencies, adding xmlns:p="http://primefaces.org/ui to the xml namespace, defining some primfaces components on my page and it works... Ok, but neither I can find the related taglib in the source or binary package nor my IDE (IntelliJ) is able to find where "xmlns:p="http://primefaces.org/ui" is pointing to. Therefore, code completion is also not possible. (all other mojarra taglibs are found.) Is it possible that PrimeFaces is defining the taglib via annotations directly in Java classes or is it generating it during runtime? I can easily find the UIComponents, primefaces defines in its source, but the configuration of the taglib seems to be missing. I am sure I just don't know how PrimeFaces is doing it, but the javaeetutorial is not describing any other opportunity than defining a ...-taglib.xml

  • If a nonblocking recv with MSG_PEEK succeeds, will a subsequent recv without MSG_PEEK also succeed?

    - by Michael Wolf
    Here's a simplified version of some code I'm working on: void stuff(int fd) { int ret1, ret2; char buffer[32]; ret1 = recv(fd, buffer, 32, MSG_PEEK | MSG_DONTWAIT); /* Error handling -- and EAGAIN handling -- would go here. Bail if necessary. Otherwise, keep going. */ /* Can this call to recv fail, setting errno to EAGAIN? */ ret2 = recv(fd, buffer, ret1, 0); } If we assume that the first call to recv succeeds, returning a value between 1 and 32, is it safe to assume that the second call will also succeed? Can ret2 ever be less than ret1? In which cases? (For clarity's sake, assume that there are no other error conditions during the second call to recv: that no signal is delivered, that it won't set ENOMEM, etc. Also assume that no other threads will look at fd. I'm on Linux, but MSG_DONTWAIT is, I believe, the only Linux-specific thing here. Assume that the right fnctl was set previously on other platforms.)

  • Is it safe to catch EXCEPTION_GUARD_PAGE

    - by Michael J
    Environment is VC++ 9 on various Win platforms (XP and later) I'm writing an unhandled exception handler. I have a vague recollection from my kernel days that it was bad to catch an EXCEPTION_GUARD_PAGE, as this was generated to tell the OS to enlarge the stack. My question is twofold: Can such an exception occur in user space? If so, is it safe to catch it? I'm not especially interested in doing anything with it. I just want to know if I need to put special code in to not catch it (as I'm catching everything at the moment).

  • Systematically resolve conflicting styles in css

    - by Frank Michael Kraft
    I have some stylesheets from different sources in my web project. I want to harmonize them. Some styles I need from the one, some from the other. Is there a tool or method how to systematically resolve style conflicts? I tried IE8 developer tool, and yes, it is possible to view conflicts at the level of each element. But I have many elemens, so if I do it element by element I think this takes too long. Theoretically there could be a tool that shows conflicts of two css files at design time?!? I think this would save me a lot of time.

  • Rails - Why is HAML showing the full hash?

    - by Mr. Demetrius Michael
    View: !!! %html %head %title= full_title(yield(:title)) =stylesheet_link_tag "application", media: "all" =javascript_include_tag "application" =csrf_meta_tags =render 'layouts/shim' %body =render 'layouts/header' .container =flash.each do |key, value| %div{class: "alert alert-#{key}"} #{value} Controller def create @user = User.new(params[:user]) if @user.save flash[:success] = "This is Correct" redirect_to @user else flash[:wrong] = "no" render 'new' end end Regardless of the flash (:success or :wrong or otherwise) it always compiles the entire hash as html (below) Output: <!DOCTYPE html> .... <div class='container'> <div class='alert alert-wrong'>no</div> {:wrong=&gt;&quot;no&quot;} </div> </body> </html> I have no idea why {:wrong=&gt;&quot;no&quot;} is being displayed. I've been staring at this terminal for hours. What's interesting is that the hash is being outputted with the container id, but not in the alert class. It feels like an indentation problem, but I went through several permutations with no success.

  • .NET C# setting the value of a field defined by a lambda selector

    - by Frank Michael Kraft
    I have a generic class HierarchicalBusinessObject. In the constructor of the class I pass a lambda expression that defines a selector to a field of TModel. protected HierarchicalBusinessObject (Expression<Func<TModel,string>> parentSelector) A call would look like this, for example: public class WorkitemBusinessObject : HierarchicalBusinessObject<Workitem,WorkitemDataContext> { public WorkitemBusinessObject() : base(w => w.SuperWorkitem, w => w.TopLevel == true) { } } I am able to use the selector for read within the class. For example: sourceList.Select(_parentSelector.Compile()).Where(... Now I am asking myself how I could use the selector to set a value to the field. Something like selector.Body() .... Field...

  • Is it safe to call a function to intialize a class in a ctor list?

    - by Michael Dorgan
    I have Angle class that I want initialized to a random value. The Angle constructor can accept an int from a random() function. Is it safe to place this call in the ctor list: foo::foo() : Angle(random(0xFFFF)) {...} or do I have to do it in the body of the constructor? foo::foo() { Angle = Angle(random(0xFFFF)); ...} If it matters, the foo class is derived from another class and does have virtual methods. In addition, no exception handling is allowed in our app.

  • Problem with absolute positioning div over SWF and IE 8.

    - by Michael S. Kelly
    I'm attempting to use the old IFrame-over-SWF trick to get HTML to display "inside" a SWF. I'm following the example provided by Brian Deitte at: http://www.deitte.com/IFrameDemo3/IFrameDemo.html. (The source code can be viewed and downloaded by right-clicking on the SWF and selecting "View Source".) In the latest versions of Firefox, Google, Opera, and Safari on the Mac, it all looks good. But in IE 8 the absolutely positioned div containing the IFrame is positioned too far up and left, and the height and width are considerably smaller. Thoughts?

  • php/mysql show data from chosen checkboxes

    - by Michael
    Hi. I have a table called FRUIT id type daysold 1 banana 5 2 apple 6 3 apple 4 4 peach 2 5 banana 6 What I would like is to have 3 checkboxes: Banana [ ] Apple [ ] Peach [ ] SUBMIT Then if I've only checked "Banana" and "Peach" the mysql output should only show me the rows that matches those two types. And the checkboxes should remain checked to highlight what was chosen. I can make the checkboxes but then that's about it really. I don't know how to properly get the info from the checkboxes and down to the WHERE argument in the MYSQL-code. Especially not with two types chosen. If it was just a dropdown menu with a single choice then I'd add the choice to the url and put WHERE type='$choice' - but I'm struggling with the multiple choices. I'm a bit of a novice at both php and mysql, so I'm a bit lost on this one.

  • iPhone iOS4: API for AVRCP (ff/rewind commands on Bluetooth headsets)

    - by Michael Kessler
    Hi, I know that AVRCP abilities were added to iOS 4.1 (in iPod application now you can forward and rewind songs by using hardware buttons on supporting headsets). I am trying to find any API for using these abilities in a music application that I work on. The requirement is to catch play/stop, forward and rewind buttons events from the headset. Any information will be more than welcome. Thank you.

  • MVC Entity Framework: Cannot open user default database. Login failed.

    - by Michael
    This type of stuff drives me nuts. I'm having trouble finding the exact issue that I'm having, maybe I just don't know the terminology. Anyway, I had a working website using MVC and Entity Framework, but then I coded an error in a partial view page (ascx). Then all of a sudden I started to get this message. Cannot open user default database. Login failed. Login failed for user 'NT AUTHORITY\SYSTEM' I've found plenty of suggestions about opening SQL Server Management Studio, Double Click on Security, Double Click on Logins, Double click on NT AUTHORITY\SYSTEM and then double click on User Mapping. In this view I'm suppose to check the box for my database so that this user is mapped to this login. However, since I created my database in Visio Studio 2008 as part of my solution, it doesn't show up to allow me to click on it. So what do I do now? What drives me nuts is that everything was working fine. I was using my computer name to access the website and everything was working fine until the coding error. I've fix the error but still getting the error. I should also mention that this error started yesterday too around the same time but later cleared itself up. If I use localhost to access the site, it works just fine. IIS7 configuration for my website: Application Pool = DefaultAppPool Physical Path Credentials Logon = ClearText With in connection strings. I do see the one for my database in this solution. Entry Type is local metadata=res://*/Models.DataModel.csdl|res://*/Models.DataModel.ssdl|res://*/Models.DataModel.msl; provider=System.Data.SqlClient; provider connection string="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\FFBall.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True" And somewhere I remember changing the identity from Network Service to LocalSystem. Because when I first stared I was getting this same message, but I changed this value and it started working. I saw that suggested somewhere too but I do not recall. Wait I remember now, I believe in IIS7, under Application Pools, DefaultAppPool identity is set to LocalSystem. Additional things I've tried. Restart the computer Recycle the application pool. Antivirus isn't running. Any help would be appreciated. Thank you in advance.

  • .NET 3.5 C# does not offer what I need for locking: Count async saves until 0 again.

    - by Frank Michael Kraft
    I have some records, that I want to save to database asynchronously. I organize them into batches, then send them. As time passes, the batches are processed. In the meanwhile the user can work on. There are some critical operations, that I want to lock him out from, while any save batch is still running asynchronously. The save is done using a TableServiceContext and method .BeginSave() - but I think this should be irrelevant. What I want to do is whenever an async save is started, increase a lock count, and when it completes, decrease the lock count so that it will be zero as soon as all have finished. I want to lock out the critical operation as long as the count is not zero. Furthermore I want to qualify the lock - by business object - for example. I did not find a .NET 3.5 c# locking method, that does fulfil this requirement. A semaphore does not contain a method to check, if the count is 0. Otherwise a semaphore with unlimited max count would do.

  • SqlCE DB occasionally freezes on one handheld, not another

    - by Michael
    I have two types of custom handhelds which are similar, but slightly different, each running the same WinForm application and a WinCE database: Type 1: WinCE 4.2, 400 mhz, 93244 kb Type 2: WinCE 5.0, 520 mhz, 84208 kb Type 1 will happily proceed through a large batch db operation (initiated) by the app, by Type 2 will consistently begin c-r-a-w-l-i-n-g (for several to many cycles) at around the 200 cycle mark. As several points it will begin running normally and then crawl again. The app does several db op's (inserts, updates and selects, no deletes). To simplify my situation, I've built a small test app which essentially does this: command_s.CommandText = "select dvr from vr where vid = 2211250"; command_u.CommandText = "update pvr set LocationID=81 where Status='OK' and vri = 27861"; while(going) { command_s.ExecuteScalar(); command_u.ExecuteNonQuery(); } and set it off running on the two units side by side. Sure enough, the slower (400 mhz) unit is outpacing the faster (520 mhz) unit (it's about 5000 cycles ahead right now) and I can see noticable pauses on the 520 mhz unit. What is causing this?

  • Using a Resource as an Attribute to a HTML Element in ASP.net

    - by Michael Stum
    I would like to have this piece of code in my .aspx file: <input class="ms-ButtonHeightWidth" type="button" name="BtnOK" id="Button2" value="Close" onclick="javascript:HandleOKButtonClick()" accesskey="<%$Resources:wss,okbutton_accesskey%>" /> Unfortunately, ASP.net doesn't seem to like that: An error occurred during the processing of /_layouts/MyPage/Info.aspx. Literal expressions like '<%$Resources:wss,okbutton_accesskey%>' are not allowed. Use <asp:Literal runat="server" Text="<%$Resources:wss,okbutton_accesskey%>" /> instead That doesn't work in this situation as that would mean nesting the Literal between the quotes of the accesskey attribute, which causes a "The tag contains duplicate 'ID' attributes" error. Is there a way to use a string from a resource without having to change the input to an asp:Button? I guess there has to be a way using <%=, but I don't know how I would address the resource itself?

  • Where would async calls make sense in an ASP.net (MVC) Web Application?

    - by Michael Stum
    I'm just wondering, if I have an ASP.net Web Application, either WebForms or MVC, is there any situation where doing stuff asynchronously would make sense? The Web Server already handles threading for me in that it spins up multiple threads to handle requests, and most request processing is rather simple and straight forward. I see some use for when stuff truly is a) expensive and b) can be parallelized. but these are the minority cases (at least from what I've encountered). Is there any gain from async in the simple "Read some input, do some CRUD, display some output" scenario?

  • Can I get Androis OS?

    I bought a umpc on ebay, A Ipad touchscreen like device. I had been looking at a particular hardware model that many sellers had, on which was running Android (1.6). I based my choice on the one that offered "free" shipping via UPS (3-5 day) delivery. after the purchase I noticed that the one I bought has Windows CE, not android (!#$^%!!!). Now I want to know if I can get a copy of Android 1.6 or higher and put it on this device. I have looked on google, Torrent sites and ebay, but cannot find a copy of Android OS
