  • Interpreting type codes in sys.objects in SQL Server

    - by fatcat1111
    On SQL Server, the sys.objects table includes "Type" and "Type_Desc" attributes. For example: SELECT DISTINCT [Type], Type_Desc FROM Sys.Objects ORDER BY [Type] Returns: C CHECK_CONSTRAINT D DEFAULT_CONSTRAINT F FOREIGN_KEY_CONSTRAINT FN SQL_SCALAR_FUNCTION FS CLR_SCALAR_FUNCTION IT INTERNAL_TABLE P SQL_STORED_PROCEDURE PK PRIMARY_KEY_CONSTRAINT S SYSTEM_TABLE SQ SERVICE_QUEUE TR SQL_TRIGGER U USER_TABLE UQ UNIQUE_CONSTRAINT V VIEW Is there a comprehensive list of these types somewhere? There isn't a constraint on sys.objects that points me to table of these, and sys.types contains data types. I've searched SQL BOL but haven't found it. Any help would be appreciated. EDIT: Some DBs use only a subset of these types. For example, if I have a database with no views, when I query Sys.Objects as above, there are no "V" rows in the results. I am looking for a list of all possible types and descriptions used by SQL Server.

  • HTML Dynamic Number of Dropdowns

    - by Evilsithgirl
    I have this form on which I would like to create a dynamic number of dropdowns. I have a list of categorized applications which I would like each to have its own dropdown that submits data for each dropdown. The dropdown options will be the same for each. Here is my code. I am not sure how to pass the unique data to the server. As you can see I currently have an iteration over a list of applications that I would like to make each select in that iteration its own dropdown. Thanks in advance. <html:form action="/CategorizeApps.do"> <h3>Uncategorized</h3> <br/> Categorize each application using the dropdown menu then click categorize.<br/> <table class="list"> <thead> <tr class="controls"> <td><input type="submit" name="btnAction" value="Categorize"/></td> </tr> <tr class="fields"> <td>ID</td> <td>Name</td> <td></td> </tr> </thead> <tbody> <logic:iterate id="uncat" name="appsUncat" scope="session"> <tr class="hlist"> <td><bean:write property="id" name="uncat" scope="page"/></td> <td><bean:write property="name" name="uncat" scope="page"/></td> <td><select id="category" name="category"> <logic:iterate id="categories" name="Categories" scope="session"> <option value="<bean:write name="categories" property="id" scope="page"/>"><bean:write name="categories" property="name" scope="page"/></option> </logic:iterate> </select></td> </tr> </logic:iterate> </tbody> </table> </html:form>

  • Expand Expandable Listview in android on button Click

    - by user3146145
    I am implementing expandable list view with its custom adapter. The group element needs to have 2 buttons, first as a parent group element and a button below it. My problem is, I want to expand the list view on click of the button below instead of the group element. Also, The group element onClick needs to call another activity. I can disable the expanding of the expandablelistview by `mainExpListView.setOnGroupClickListener(new OnGroupClickListener() { @Override public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) { return false; }` So my questions: Is there any way to disable the group element and get it to perform other functions (Like navigate to another activity?) How to set an onclick method on them bottom image to expand? Thank you.

  • Another Permutation Word Conundrum... With Linq?

    - by CraigF
    I have seen many examples of getting all permutations of a given set of letters. Recursion seems to work well to get all possible combinations of a set of letters (though it doesn't seem to take into account if 2 of the letters are the same). What I would like to figure out is, could you use linq (or not) to get all possible combinations of letters down to 3 letter combinations. For example, given the letters: P I G G Y I want an array of all possible cominations of these letters so I can check against a word list (scrabble?) and eventually get a list of all possible words that you can make using those letters (from 3 letters up to the total, in this case 5 letters).

  • Is there a difference between `==` and `is` in python?

    - by Bernard
    My Google-fu has failed me. In Python, are these: n = 5 # Test one. if n == 5: print 'Yay!' # Test two. if n is 5: print 'Yay!' two tests for equality equivalent (ha!)? Does this hold true for objects where you would be comparing instances (a list say)? Okay, so this kind of answers my question: l = list() l.append(1) if l == [1]: print 'Yay!' # Holds true, but... if l is [1]: print 'Yay!' # Doesn't. So == tests value where is tests to see if they are the same object?

  • AutoMapper: How to transform object graph to into?

    - by epitka
    If I have a one-to-many relationship and I want to transorm this into a list of flat Dto-s where some attributes of parent and some of child appear in a dto, is this something that is supported out-of-box with AutoMapper? For example if I have something like this Parent 1. ParentId 2. ParentAttr1 3. List<Child> Child 1. ChildId 2. ChildAttr1 2. ChildAttr2 Dto 1. ParentId 2. ChildId 2. ChildAttr1 3. ChildAttr2 How do I project Parent into a Dto where for each child in parent I will get an instace of Dto? I've setup two maps Parent-Dto and Child-Dto but just doing _mapper.Map(parentInstance) only projects parents attributes. Does this have to be done in two steps, where I would iterate children myself?

  • How do i translate this to "simpler" JavaScript?

    - by Julian Weimer
    Since i'm working with Titanium i realzed that its current JavaScript Interpreter doesn't accept specific coding-styles. So for for-loops and if-statements i have to have braces, even though i only want to span one line. Furthermore there is more i have to change if i want to use a Javascript Library like underscore.js. This is what Titanium doesn't want to see: if (!(result = result && iterator.call(context, value, index, list))) {_.breakLoop();} if (nativeSome && obj.some === nativeSome) {return obj.some(iterator, context);} var computed = iterator ? iterator.call(context, value, index, list) : value; computed >= result.computed && (result = {value : value, computed : computed}); Can i use a simpler syntax to describe the logic behind those lines of code?

  • Listing and deleting Git commits that are under no branch (dangling?)

    - by Samer Abukhait
    I've got a git repository with plenty of commits that are under no particular branch, I can git show them but when I try to list branches that contain them, it reports back nothing: I thought this is the dangling commits/tree issue (as a result of -D branch), so I pruned the repo, but I still see the case after that: $ git fetch origin $ git fsck --unreachable $ git fsck No output, nothing dangling (right?) $ git show 793db7f272ba4bbdd1e32f14410a52a412667042 commit 793db7f272ba4bbdd1e32f14410a52a412667042 Author: .. But $ git branch --contains 793db7f272ba4bbdd1e32f14410a52a412667042 Gives no output What exactly is the state of that commit? How can I list all commits with similar state, How can I delete commits like those?

  • Drupal form being rendered before submit action

    - by alxp
    I have a Drupal module page where I am populating a form with a drop-down that contains a list of available parts of a set of files that the user can upload. Once the user uploads a file of a certain type, it removes that option from the list, and when all the available files are uploaded the form will not be rendered. The problem is that Drupal is drawing the form before it carries out the submit action, so it appears to the user that the operation didn't work until they reload the page. What is the common way to deal with this? Setting form_state['redirect'] to go to the page doesn't seem to work.

  • Regular expression replacing only if contained withing a regular expression match?

    - by Tower
    Hi, I have the following: [list] [*] test [*] test [*] test [/list] and I would like to create a regular expression that turns that into: <ul> <li>test</li> <li>test</li> <li>test</li> </ul> I know regex enough to replace simple tags, but in this case I need to replace li tags only if they are contained inside ul. Is there a way to check that before replacing? I am using JavaScript if that matters.

  • RESTful API: How to handle translated textfields in representations?

    - by Jan P.
    I am designing a RESTful API for a booking application. There are accommodations that you can request a list or the details. As the application targets a multi-language audience, the descriptions are (sometimes) available in different languages. Now I'm not sure how to handle these translations in the representation of an accommodation. Without the multiple languages I would make "description" a field or the accommodation object, quite simple. Any idea how to solve this elegantly? My current idea: Add a list of descriptions with text<-culture pairs instead of the description field and an additional subressource /descriptions to the accommodation for the creating (POST), updating (PUT) and deleting (DELETE) of new translations.

  • How to organise a many to many relationship in MongoDB

    - by Gareth Elms
    I have two tables/collections; Users and Groups. A user can be a member of any number of groups and a user can also be an owner of any number of groups. In a relational database I'd probably have a third table called UserGroups with a UserID column, a GroupID column and an IsOwner column. I'm using MongoDB and I'm sure there is a different approach for this kind of relationship in a document database. Should I embed the list of groups and groups-as-owner inside the Users table as two arrays of ObjectIDs? Should I also store the list of members and owners in the Groups table as two arrays, effectively mirroring the relationship causing a duplication of relationship information? Or is a bridging UserGroups table a legitimate concept in document databases for many to many relationships? Thanks

  • What are good uses for Python3's "Function Annotations"

    - by agscala
    Function Annotations: PEP-3107 I ran across a snippet of code demonstrating Python3's function annotations. The concept is simple but I can't think of why these were implemented in Python3 or any good uses for them. Perhaps SO can enlighten me? How it works: def foo(a: 'x', b: 5 + 6, c: list) -> max(2, 9): ... function body ... Everything following the colon after an argument is an 'annotation', and the information following the -> is an annotation for the function's return value. foo.func_annotations would return a dictionary: {'a': 'x', 'b': 11, 'c': list, 'return': 9} What's the significance of having this available?

  • Finding a Eulerian Tour

    - by user590903
    I am trying to solve a problem on Udacity described as follows: # Find Eulerian Tour # # Write a function that takes in a graph # represented as a list of tuples # and return a list of nodes that # you would follow on an Eulerian Tour # # For example, if the input graph was # [(1, 2), (2, 3), (3, 1)] # A possible Eulerian tour would be [1, 2, 3, 1] I came up with the following solution, which, while not as elegant as some of the recursive algorithms, does seem to work within my test case. def find_eulerian_tour(graph): tour = [] start_vertex = graph[0][0] tour.append(start_vertex) while len(graph) > 0: current_vertex = tour[len(tour) - 1] for edge in graph: if current_vertex in edge: if edge[0] == current_vertex: current_vertex = edge[1] else: current_vertex = edge[0] graph.remove(edge) tour.append(current_vertex) break return tour graph = [(1, 2), (2, 3), (3, 1)] print find_eulerian_tour(graph) >> [1, 2, 3, 1] However, when submitting this, I get rejected by the grader. I am doing something wrong? I can't see any errors.

  • Core Data strategy using in memory cache, or no core data at all?

    - by randombits
    I have a user interface where the user can check off a bunch of items from a tableview, almost like a todo list. The items are populated from a Core Data stack. I need to be able to take all of the items they're clicking through and put them into a "temporary" shopping cart. Once they're in the shopping cart, users can go through the list and remove the items, or just submit them to a server. The thing is, the selected items are temporary just like an internet based shopping cart. It's nothing something that gets persisted once the application closes. Once the view is no longer in display, I can assume that the shopping cart is safe to discard. What's the best way to approach this? Since the user is essentially clicking on instances that map back to a Core Data entity .. should I setup a different persistence store such as in memory and add that store to my managed object context?

  • The type{0} does not support direct content - WPF / XAML

    - by Levo
    Hi there: I defined in my code two classes: a "Person" class with public "Age" and "Name" property, and a "People" class that inherits from Generic.List(of T). The code for People class is as followed: Public Class People Inherits Collections.Generic.List(Of Person) ... End Class What I want to achieve is to directly initialize the People class, and add individual Person to it in XAML, i.e.: <local:People x:Key="Familty"> <local:Person Age="11" Name="John" /> <local:Person Age="12" Name="John2" /> ... </local:People> But I keep getting an error in XAML saying: The type 'People' does not support direct content. Any idea as for how to solve this problem? Thank you very much!

  • What is the purpose of this delegate usage?

    - by Kev
    Whilst poking around some code in .NET Reflector in an app I don't have the source code for I found this: if (DeleteDisks) { using (List<XenRef<VDI>>.Enumerator enumerator3 = list.GetEnumerator()) { MethodInvoker invoker2 = null; XenRef<VDI> vdiRef; while (enumerator3.MoveNext()) { vdiRef = enumerator3.Current; if (invoker2 == null) { // // Why do this? // invoker2 = delegate { VDI.destroy(session, vdiRef.opaque_ref); }; } bestEffort(ref caught, invoker2); } } } if (caught != null) { throw caught; } private static void bestEffort(ref Exception caught, MethodInvoker func) { try { func(); } catch (Exception exception) { log.Error(exception, exception); if (caught == null) { caught = exception; } } } Why not call VDI.destroy() directly. Is this just a way of wrapping the same pattern of try { do something } catch { log error } if it's used a lot?

The logs are logged in a logfile process ID appended to each line. Prog to find out if the test case has passed or failed. The program shoud be running till the processes are running and display output.

  • Json Object to a Multidimensional C# Array?

    - by Nick Brooks
    Is there a way to convert a Json Object to a Multidimensional C# Array? I know it might be impractical but I can't be bothered to write classes and then deserialize the strings into them. List<string> ohyeah = (List<string>)JsonConvert.DeserializeObject(g.CommToken); That returns an Invalid Cast exception! Example: {"method":"getCommunicationToken","header":{"uuid":"9B39AAB0-49A6-AC7A-BA74-DE9DA66C62B7","clientRevision":"20100323.02","session":"c0d3e8b5d661f74c68ad72af17aeb5a1","client":"gslite"},"parameters":{"secretKey":"d9b687fa10c927f102cde9c085f9377f"}} I need to get something like that : j["method"]; //This will equal to getCommunicationToken j["header"]["uuid"]; //This will equal to 9B39AAB0-49A6-AC7A-BA74-DE9DA66C62B7 I literally need to parse the json object into an array.

  • Is it possible to start an activity in a different apk using startActivity on Android using the acti

    - by icecream
    I have tried to write an Android application with an activity that should be launched from a different application. It is not a content provider, just an app with a gui that should not be listed among the installed applications. I have tried the code examples here and it seems to be quite easy to launch existing providers and so on, but I fail to figure out how to just write a "hidden" app and launch it from a different one. The basic use case is: App A is a normal apk launchable from the application list. App B is a different apk with known package and activity names, but is is not visible or launchable from the application list. App A launches app B using the package and class names (or perhaps a URI constructed from these?). I fail in the third step. Is it possible to do this?

  • How can I implement drag-out-to-delete in Flex?

    - by Chris R
    I have a List component from which I'd like to be able to remove items using drag & drop, but without having a specific target. If you use the mac, the behaviour I'm looking for is something like what the Dock uses; when you drag something out of the bounds of the control it should get an icon that indicates that it'll be deleted (OSX uses a cloud or something?) and then if you release it it will be removed from the list. How can I do this? (If I need to provide a more clear description, please comment; I'll fill in what I can)
