  • How do you access config outside of a request in CherryPy?

    - by OrganicPanda
    I've got a webapp running on CherryPy that needs to access the CherryPy config files before a user creates a request. The docs say to use: host = cherrypy.request.app.config['database']['host'] But that won't work outside of a user request. You can also use the application object when you start the app like so: ... application = cherrypy.tree.mount(root, '/', app_conf) host = application.config['database']['host'] ... But I can see no way of accessing 'application' from other classes outside of a user request. I ask because our app looks at several databases and we set them up when the app starts rather than on user request. I have a feeling this would be useful in other places too; so is there any way to store a reference to 'application' somewhere or access it through the CherryPy API?

  • WIX: Using a temporary file during install

    - by madbadger
    Hello! I am writing a WIX installer and I have a following requirement: During installation, I need to pass an absolute path to a file (lets call it A) included in my installer to a COM component, which already exists on the hard drive and is a part of another program. I have already written an appropriate Custom Action which expects a path to the file A. I don't want to include A as a file installed in the Program Files folder and removed during the uninstallation process. Instead, I would like to put A only temporary on the hard drive, call my Custom Action which will cause the COM component to use the content of A, and then remove A from disk. Is there an easy way to accomplish this goal? I have tried to utilize the Binary Table and store A there, however I don't know how to reference A using absolute path. I know I could put A outside of MSI file but I would like to keep every file installer needs in a single MSI. Any help would be appreciated.

  • What is Mono Behaviour?

    - by Starkers
    I'm getting this message multiple times when I try to run my game: The referenced script on this Behaviour is missing For some reason, all my prefabs are missing a script that dictates something called their 'Mono Behaviour': What is the Mono Behaviour component, and what does it do? How can I fix this error? I can click the little target circle to bring up all my scripts, but that just gives me all of the scripts that I've written: So I don't really know how to replace my missing Mono Behaviour script... Maybe if I knew what it was I could have a clue how to fix it. I probably moved something. But how can I select the Mono Behaviour script (whatever it is) if the target just shows me my scripts? Update I've moved some assets in the project window, but not via the OS (Finder/Explorer) so why is this happening? Also I am told that Mono Behaviour is a script I've applied... Don't really get this...isn't the script component a reference to a script?

  • Entity framework (3.5): How to translate a certain LINQ query to eSQL?

    - by Sebastian P.R. Gingter
    Hi there, I have the following LINQ query that I need to translate to Entity SQL /eSQL): return (ObjectQuery<User>) from user in Users where !user.Roles.Any(r => r.AnIntegerProperty < 0) select user; User.Roles is an navigation property to the n:m relation to Roles and there also is a Role.Users navigation property the other way round. There aren't User_Roles or Roles_User Entities available in the model, and I can't add these. I also can't use the LINQ statement here, because I need to add .OrderBy("it." + propertyname) (comes from another source, can't change that too) later on which is not possible if the ObjectQuery is build with linq. So how do I translate this to eSQL? And where can I find good eSQL samples? I searched for a whole day until now and must admit that eSQL reference is lousy and there aren't any usable examples around the web.

  • MYSQL Inner Join two table over two keys

    - by bertsisterwanda
    I am doing a query to return all users shopping carts, stored in the sb_carts table. The product information stored in sb_carts is referenced over two keys product_sku and school_id. It needs to reference both to return a unique product with unique stock levels etc. When I execute the following query it returns one row, I am expecting 3 rows. I have tried breaking the inner join into two separate joins but this still returns only 1 result. joining only on one key has the desired result, but may be retuning the wrong product. A left join returns 3 rows but some data is missing product specific Here is a simplified example of what I am doing SELECT sb_carts.product_sku FROM sb_carts INNER JOIN sb_products ON sb_products.sku = sb_carts.product_sku AND sb_products.school_id = sb_carts.school_id WHERE sb_carts.order_id = 0 AND sb_carts.user_id = 2 GROUP BY sb_carts.cart_id

  • How do I do multiple assignment in MATLAB?

    - by Benjamin Oakes
    Here's an example of what I'm looking for: >> foo = [88, 12]; >> [x, y] = foo; I'd expect something like this afterwards: >> x x = 88 >> y y = 12 But instead I get errors like: ??? Too many output arguments. I thought deal() might do it, but it seems to only work on cells. >> [x, y] = deal(foo{:}); ??? Cell contents reference from a non-cell array object. How do I solve my problem? Must I constantly index by 1 and 2 if I want to deal with them separately?

  • Flex 4 how to layout spark controls in an html table type way

    - by Amy
    I have a group of controls and I want to organize them in a table like fashion. I want 1 row and 6 columns. Col 1,3,4,5,6 should all auto size to the contents and col 2 should take up the remaining available space. When the size of the group changes, only col2 width should change. I also want to be able to set the alignment of each cell. How can I do this in flex 4? I found a reference to mx:constraintColumns but this seems to be used with the canvas and in flex 4 adobe suggests not using canvases. Is there something similar in flex 4? I'm looking for something along the lines of Grid/Grid.ColumnDefinitions in silverlight.

  • Does retrieving an object from Doctrine2 cause __construct() of the model class to run?

    - by jiewmeng
    When I retrieve an object say by $em->find('Application\Models\User', 1); or other methods like DQL, findBy*() cause the __construct() of the model class to run? I am having a problem where I set variables there like reference to EntityManager and I find that its not set. I tried putting a die() in __construct() and it doesn't halt the application. Can I say that if I want to set other properties/fields like EntityManager $em I have to do it some other way? Perhaps something like protected function getEm() { if (!isset($this->em)) { $this->em = \Zend_Registry::get('em'); } return $this->em; }

  • With ASP .NET, how do I display a side submenu depending on what user picked from the main menu?

    - by Ole Media
    Hello, I come from PHP side, but I'm in need to develop a site using ASP .NET So far I manage to create a master page. Now I'm dealing with menus and submenus What I'm trying to do is, if the user picks "About Us" from the main menu, under the about us page I want to display a submenu with the options "who we are, what we do, contact us" If the user picks "Our Products" from the main menu, then under the products page I want to display a submenu with the options "product 1, product 2, product 3" Is this possible with only one master page? I read something about menu control but not sure that is what I need. So far I found how to display a sitemap, but not specific sections of a sitemap, if this is the way to do things. Any links, sample code, point of reference will be appreciated. Thanks

  • Optional Fields in Infopath; Getting the xml node with VBA

    - by Sunscreen
    Hi all, I use vb to get data through my form. I have some optional fileds in my form and I have this problem with the following code: MsgBox(myXPathNavigator.SelectSingleNode("/my:Status/my:Questions/my:Questions1", _ Me.NamespaceManager).IsNode.ToString) When the optional filed 'Questions1' is inserted to the form I get the value 'true' by the IsNode function. If the field it is not inserted I have an exception, stating that the reference is not correct (and it is indeed true). Is there a way to verify about a node, whether it is present or not in my form? Thanks in advance, Sun

  • Using C# Type as generic

    - by I Clark
    I'm trying to create a generic list from a specific Type that is retrieved from elsewhere: Type listType; // Passed in to function, could be anything var list = _service.GetAll<listType>(); However I get a build error of: The type or namespace name 'listType' could not be found (are you missing a using directive or an assembly reference?) Is this even possible or am I setting foot onto C# 4 Dynamic territory? As a background: I want to automatically load all lists with data from the repository. The code below get's passed a Form Model whose properties are iterated for any IEnum (where T inherits from DomainEntity). I want to fill the list with objects of the Type the list made of from the repository. public void LoadLists(object model) { foreach (var property in model.GetType() .GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.SetProperty)) { if (IsEnumerableOfNssEntities(property.PropertyType)) { var listType = property.PropertyType.GetGenericArguments()[0]; var list = _repository.Query<listType>().ToList(); property.SetValue(model, list, null); } } }

  • Android EditText within a ListView

    - by metalideath
    I have created a custom Array Adapter to bind a custom row that contains some static text and an editable EditText. I am trying to register to be notified when the user changes the text within the edit text and when notified to determine which ArrayList row the modified EditText corresponds to. In the past with other types of views such as a Spinner I could simply put a reference to the parent view and the row number into the tag for the Spinner view. And then when I was notified that the value changed I read the tag to determine how to correlate it back to the master ArrayList. The problem with registering to be notifed with an EditText change is that you do not get back a view but instead get a TextWatcher and I have no way to correlate back to the parent view or ArrayList row. What is the technique that you need to use in this circumstance?

  • LINQ and paging with a DataTable - can't get Skip working?

    - by Kit Menke
    Ok so this might be a dumb question, but I can't seem to figure it out. I thought I'd try out LINQ against a DataTable. I got my query working and now I'm trying to implement some simple paging. DataTable dataTable = null; dataTable = GetAllDataTables(); var query = from r in dataTable.AsEnumerable() orderby r.Field<string>(Constants.fileName) select r; query.Skip(WPP_PAGE_SIZE * pageIndex).Take(WPP_PAGE_SIZE); My problem is that I get an error at query.Skip(...). Error 1 'System.Data.OrderedEnumerableRowCollection' does not contain a definition for 'Skip' and no extension method 'Skip' accepting a first argument of type 'System.Data.OrderedEnumerableRowCollection' could be found (are you missing a using directive or an assembly reference?) References I have: Microsoft.SharePoint System System.Core System.Data System.Data.DataSetExtensions System.Web System.Xml What am I missing?

  • When does a MySQL Query actually execute in PHP?

    - by MJB
    This sounds like a really simple question, but I am new to PHP. If I have a statement like this: $r =& $db->query("insert into table (col1, col2) values (10, 20)"); Do I have to still execute it, or does it get executed when I reference it? I have another case where I have a select query, which seems logically to run only when I call fetchrow, but the code I am presented with (to fix) does not call execute or fetch.I would have expected it to, so I cannot tell if it is just that I don't get it, or that the missing execute statement is the problem. It also does not insert the record, but it does not throw an error I can find. Also, I am a little confused by the =& notation. I looked it up on google, and found a few mentions of it, but I am still not clear on it. Thanks.

  • Can I "inherit" a delegate? Looking for ways to combine Moq and MSpec without conflicts around It...

    - by Tomas Lycken
    I have started to use MSpec for BDD, and since long ago I use Moq as my mocking framework. However, they both define It, which means I can't have using Moq and using Machine.Specifications in the same code file without having to specify the namespace explicitly each time I use It. Anyone who's used MSpec knows this isn't really an option. I googled for solutions to this problem, and this blogger mentions having forked MSpec for himself, and implemented paralell support for Given, When, Then. I'd like to do this, but I can't figure out how to declare for example Given without having to go through the entire framework looking for references to Establish, and changing code there to match that I want either to be OK. For reference, the Establish, Because and It are declared in the following way: public delegate void Establish(); public delegate void Because(); public delegate void It(); What I need is to somehow declare Given, so that everywhere the code looks for an Establish, Given is also OK.

  • Qt compilation and stylesheet

    - by Yosko
    Each time I compile my Qt project after modifying my qss stylesheet file, the modifications aren't taken into account, unless I rebuild everything. Any idea on a workaround for this, so that I don't have to wait 5 minutes each time I change my qss ? Notes: I use Qt 4.8, and my stylsheet is declared in a resource file (qrc). EDIT: As suggested by Luca Carlon, when a qss is reference in the project through a .qrc file, the changes in the qss don't affect the qrc, and the compiler ignores it. To avoid that, I added a Custom Build Step to my project: before the qmake step! calls a .bat file without any argument the .bat contains the real command copy /b files.qrc +,,

  • InvalidOperationException when using soap client

    - by codymanix
    I've added as wsdl file using the add servece reference dialog in vs2008. MyService serviceproxy = new MyService(); When I instantiate the service proxy, I get an InvalidOperationException with the following text (translated from german): Could not find default endpoint element to the contract "ServiceName.ServiceInterface" in the service model refers client configuration section. This may be because: The application configuration file was not found or not an endpoint in the client element item is found, which corresponded to this contract. Where servicename is the name I give the service when I add it in vs2008 and ServiceInterface the interface which is automatically generated for it.

  • Most efficient approach for multilingual PHP website

    - by alexteg
    I am working on a large multilingual website and I am considering different approaches for making it multilingual. The possible alternatives I can think of are: The Gettext functions with generation of .po files One MySQL table with the translations and a unique string ID for each text PHP-files with arrays containing the different translations with unique string IDs As far as I have understood the Gettext functions should be most efficient, but my requirement is that it should be possible to change a text string in the original reference language (English) without the other translations of that string automatically reverting back to English just because a couple of words changed. Is this possible with Gettext? What is the least resource demanding solution? Is using the Gettext functions or PHP files with arrays more or less equally resource demanding? Any other suggestions for more efficient solutions?

  • PropertyInfo SetValue and nulls

    - by Nelson
    If I have something like: object value = null; Foo foo = new Foo(); PropertyInfo property = Foo.GetProperties().Single(p => p.Name == "IntProperty"); property.SetValue(foo, value, null); Then foo.IntProperty gets set to 0, even though value = null. It appears it's doing somemething like IntProperty = default(typeof(int)). I would like to throw an InvalidCastException if IntProperty is not a "nullable" type (Nullable< or reference). I'm using Reflection, so I don't know the type ahead of time. How would I go about doing this?

  • Dynamic classloading fails on runtime

    - by Henrik Paul
    I have the following snippet of java code: final Class<?> junitCoreClass = AccessController.doPrivileged( new PrivilegedAction<URLClassLoader>() { @Override public URLClassLoader run() { return new URLClassLoader(new URL[] { junitJarUrl }); } }).loadClass("org.junit.runner.JUnitCore"); System.out.println(junitCoreClass.getName()); final JUnitCore junitCore = (JUnitCore) junitCoreClass.newInstance(); This compiles fine. But when I try to run it, something weird happens; a java.lang.NoClassDefFoundError is thrown on that last line, referring to the class just loaded. The weird part is, the println prints the exact class name. I checked that if I keep the reference as an Object and manipulate it only through reflection, everything's fine, so the offending piece of code must be the explicit cast. Can someone explain to me why this happens, and also tell me how I can achieve what I'm trying to do?

  • How do I add multiple joins (Fetches) to a joined table using nhibernate and LINQ ?

    - by ooo
    i have these tables /entities VacationRequestDate table which has a VacationRequestId field that links with VacationRequest table VacationRequest has PersonId and RequestStatusId fields that links with Person and RequestStatus respectively. i have this query so far: IEnumerable<VacationRequestDate> dates = Session.Query<VacationRequestDate>().Fetch(r => r.VacationRequest).ThenFetch(p=>p.RequestStatus).ToList(); this works fine and joins with VacationRequest and then VacationRequest joins with RequestStatus but i can't figure out how to add an additional EAGER join to the VacationRequest table. If i add a Fetch at the end, it refers to the VacationRequestDate table If i add a ThenFetch at the end, it refers to the RequestStatus table I can't find any api that will refer to the VacationRequest table as the reference point. how would you add multiple joins to a joined table using nhibernate LINQ ?

  • C#: Problem trying to resolve a class when two namespaces are simmilar.

    - by rally25rs
    I'm running into an issue where I can't make a reference to a class in a different namespace. I have 2 classes: namespace Foo { public class Class1 { ... } } namespace My.App.Foo { public class Class2 { public void SomeMethod() { var x = new Foo.Class1; // compile error! } } } The compile error is: The type or namespace name 'Class1' does not exist in the namespace 'My.App.Foo' In this situation, I can't seem to get Visual Studio to recognize that "Foo.Class1" refers to the first class. If I mouse-over "Foo", it shows that its trying to resolve that to "My.App.Foo.Class1" If I put the line: using Foo; at the top of the .cs file that contains Class2, then it also resolves that to "My.App.Foo". Is there some trick to referencing the right "Foo" namespace without just renaming the namespaces so they don't conflict? Both of these namespaces are in the same assembly.

  • Lifetime of javacript variables.

    - by The Machine
    What is the lifetime of a variable in javascript, declared with "var". I am sure, it is definitely not according to expectation. <script> function(){ var a; var fun=function(){ // a is accessed and modified } }(); </script> Here how and when does javascript garbage collect the variable a? Since 'a' is a part of the closure of the inner function, it ideally should never get garbage collected, since the inner function 'fun', may be passed as a reference to an external context.So 'fun' should still be able to access 'a', from the external context. If my understanding is correct, how does garbage collection happen then, and how does it ensure to have enough memory space, since keeping all variables in memory until the execution of the program might not be tenable ?
