  • Android - ListView click HOWTO?

    - by teepusink
    Hi, How do I listen to click event on a ListView? This is what I have now ListView list = (ListView)findViewById(R.id.ListView01); ... list.setAdapter(adapter); When I do the following list.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { public void onItemSelected(AdapterView parentView, View childView, int position, long id) { setDetail(position); } public void onNothingSelected(AdapterView parentView) { } }); That doesn't seem to do anything on click. And all those code live within a class that extends Activity. Thanks, Tee

  • NHibernate: QueryOver<> help

    - by Andy Baker
    Hi, I'm just starting out with NHibernate and I'm having trouble with running more complex queries. I have entities with a list of tags attached. The user will provide two lists of tags, include and exclude. I need to find all the entities that have all of the include tags, and exclude any entites that have any tag in the exclude list. Below is my first effort- which is clearly wrong as its listing all Display objects that have any of the include tags rather than all! Any assistance is greatly appeciated. var includeTagIds = (from tag in regime.IncludeTags select tag.Id).ToList<int>(); var excludeTagIds = from tag in regime.ExcludeTags select tag.Id; var displays = session.QueryOver<Display>() .JoinQueryOver<DisplayTag>(display => display.Tags) .WhereRestrictionOn(tag => tag.Id) .IsIn(includeTagIds).List().Distinct(); return displays.ToList();

  • How to create an ObservableCollection using LINQ in Silverlight

    - by sonofpirate
    In a non-Silverlight world, it is easy to use LINQ to create an ObservableCollection. This is because the ObservableCollection class has constructors that accept any IEnumerable<T or List<T. However, the Silverlight version does not! This means that code such as: var list = (from item in e.Result select new ViewModel(item)).ToList(); Items = new System.Collections.ObjectModel.ObservableCollection<ViewModel>(list); will not work in Silverlight. Is there another option to make this work besides resorting to a for-each statement?

  • C# How can I tell if an IEnumerable is Mutable?

    - by Logan
    I want a method to update certain entries of an IEnumerable. I found that doing a foreach over the entries and updating the values failed as in the background I was cloning the collection. This was because my IEnumerable was backed by some LINQ-SQL queries. By changing the method to take a List I have changed this behavior, Lists are always mutable and hence the method changes the actual objects in the list. Rather than demand a List is passed is there a Mutable interface I can use? // Will not behave as consistently for all IEnumerables public void UpdateYesterday (IEnumerable<Job> jobs) { foreach (var job : jobs) { if (job.date == Yesterday) { job.done = true; } } }

  • new[n] and delete every location with delete instead the whole chunk with delete[]

    - by pmr
    Is this valid C++ (e.g. not invoking UB) and does it achieve what I want without leaking memory? valgrinds complains about mismatching free and delete but says "no leaks are possible" in the end. int main() { int* a = new int[5]; for(int i = 0; i < 5; ++i) a[i] = i; for(int i = 0; i < 5; ++i) delete &a[i]; } The reason I'm asking: I have a class that uses boost::intrusive::list and I new every object that is added to that list. Sometimes I know how many objects I want to add to the list and was thinking about using new[] to allocate a chunk and still be able to delete every object on its own with the Disposer-style of boost::intrusive.

  • Finding all domains registered in a nameserver

    - by Florian
    Up until now, I was pretty confident that it was pretty much impossible to list all the domains handled by a nameserver. But apparently, there exists a couple of websites on the Internet that are able to list all the domains registered in a namerserver. For example: http://www.gwebtools.com/ns-spy/udns1.ultradns.net Or all domains pointing to a specific IP : http://www.robtex.com/ip/190.7.200.92.html (These DNS/IP were picked at random) Do you know how it's done ?

  • How to Zip one IEnumerable with itself

    - by wageoghe
    I am implementing some math algorithms based on lists of points, like Distance, Area, Centroid, etc. Just like in this post: http://stackoverflow.com/questions/2227828/find-the-distance-required-to-navigate-a-list-of-points-using-linq That post describes how to calculate the total distance of a sequence of points (taken in order) by essentially zipping the sequence "with itself", generating the sequence for Zip by offsetting the start position of the original IEnumerable by 1. So, given the Zip extension in .Net 4.0, assuming Point for the point type, and a reasonable Distance formula, you can make calls like this to generate a sequence of distances from one point to the next and then to sum the distances: var distances = points.Zip(points.Skip(1),Distance); double totalDistance = distances.Sum(); Area and Centroid calculations are similar in that they need to iterate over the sequence, processing each pair of points (points[i] and points[i+1]). I thought of making a generic IEnumerable extension suitable for implementing these (and possibly other) algorithms that operate over sequences, taking two items at a time (points[0] and points[1], points[1] and points[2], ..., points[n-1] and points[n] (or is it n-2 and n-1 ...) and applying a function. My generic iterator would have a similar signature to Zip, but it would not receive a second sequence to zip with as it is really just going to zip with itself. My first try looks like this: public static IEnumerable<TResult> ZipMyself<TSequence, TResult>(this IEnumerable<TSequence> seq, Func<TSequence, TSequence, TResult> resultSelector) { return seq.Zip(seq.Skip(1),resultSelector); } With my generic iterator in place, I can write functions like this: public static double Length(this IEnumerable<Point> points) { return points.ZipMyself(Distance).Sum(); } and call it like this: double d = points.Length(); and double GreensTheorem(Point p1, Point p1) { return p1.X * p2.Y - p1.Y * p2.X; } public static double SignedArea(this IEnumerable<Point> points) { return points.ZipMyself(GreensTheorem).Sum() / 2.0 } public static double Area(this IEnumerable<Point> points) { return Math.Abs(points.SignedArea()); } public static bool IsClockwise(this IEnumerable<Point> points) { return SignedArea(points) < 0; } and call them like this: double a = points.Area(); bool isClockwise = points.IsClockwise(); In this case, is there any reason NOT to implement "ZipMyself" in terms of Zip and Skip(1)? Is there already something in LINQ that automates this (zipping a list with itself) - not that it needs to be made that much easier ;-) Also, is there better name for the extension that might reflect that it is a well-known pattern (if, indeed it is a well-known pattern)? Had a link here for a StackOverflow question about area calculation. It is question 2432428. Also had a link to Wikipedia article on Centroid. Just go to Wikipedia and search for Centroid if interested. Just starting out, so don't have enough rep to post more than one link,

  • issues horizontal scrolling using jQuery.ScrollTo / jQuery.SerialScroll

    - by kapil.israni
    Hi, I am trying to develop auto horizontal scrolling for our website using - jQuery.ScrollTo / jQuery.SerialScroll. I am not sure if this is the best jquery library to do that, but if there's something better, please let me know. Here's the behavior that I want, check out foursquare's "Recent Activity" list. The data that will refresh will come from a ajax request that I make every few seconds using window.setInterval. I am not really a CSS/java script guy so I havent been able to figure out jQuery.SerialScroll. Here's the website - look at the "Live job Feeds" list. Currently the list does refresh the data coming from the ajax call, but I dont see the effect, the animation, in fact I dont even think serialScroll is being used. Right now I am doing a - $('#feed-ticker').prepend(content) to pre-append the newly arrived data. You can do a view source to look at the current code. Any help would be really appreciated. Thanks.

  • Wpf datagrid row not updating when binded collection updated?

    - by RAJ K
    I have product class class Products { public int ProductID { get; set; } public int Quantity { get; set; } public string Description { get; set; } public decimal Price { get; set; } public decimal SubTotal { get; set; } } public List<Products> ProductsList = new List<Products>(); I have binded this "ProductList" to wpf datagrid. This datagrid shows item already in collection (before DataGrid.DataContext applied) but not showing new item added. I am using List< instead of ObservableCollection< because I want to update items if user changes quantity. I don't know how to do that using ObservableCollection<. Some code will help thanks

  • Can I create a custom plist structure definition?

    - by Ed Marty
    When editing plist files in XCode, it can detect the type of plist and show human-readable strings to make it more easy to edit the file. The Info.plist, for example. Thanks to This question, I found the (or a) place where it stores that structure definition, as InfoPlistStructDefs.xcodeplugin. If I put my own file in there, however, nothing interesting happens. That is, it doesn't show up in the list of possible property list types. So does anybody know how to make XCode or the external property list editor application recognize a custom plist structure definition?

  • nmake makefile, linking objects files in a subfolder

    - by Gauthier
    My makefile defines a link command: prod_link = $(LINK) $(LINK_FLAGS) -o$(PROD_OUT) $(PROD_OBJS) where $(PROD_OBJS) is a list of object files of the form: PROD_OBJS = objfile1.obj objfile2.obj objfile3.obj ... objfileN.obj Now the makefile itself is at the root of my project directory. It gets messy to have object and listing files at the root, I'd like to put them in a subfolder. Building and outputing the obj files to a subfolder works, I'm doing it with suffixes and inference: .s.obj: $(ASSEMBLY) $(FLAGS) $*.s -o Objects\$*.obj The problem is to pass the Objects folder to the link command. I tried: prod_link = $(LINK) $(LINK_FLAGS) -o$(PROD_OUT) Objects\$(PROD_OBJS) but only the first file in the list of object files gets the folder's name. How can I pass the Objects subfolder to all files of my list $(PROD_OBJS)? EDIT I tried also PROD_OBJS = $(patsubst %.ss,Object\%.obj, $(PROD_SRC)) but got: makefile(51) : fatal error U1000: syntax error : ')' missing in macro invocation Stop. This is quite strange...

  • naming conventions for buttons in user interface

    - by Samuel
    User interface for web applications in general contain various buttons for performing CRUD operations. What would be the suggested naming convention for button labels while performing the following actions.. User creation (Add User... or Add User or Add user) Event creation (Add Event... or Add Event or Add event) View users button (List All Users or List All users or List all users ) Most of the sites seem to contain the last option (e.g. Add user) where the first alphabet in the word is capitalized and rest all are lower case). What would be a better practice here?

  • Inspecting Lucene.NET index with Luke want to replicate NHibernate.Search view

    - by Tim Peel
    Hi, I am trying to put together an index using terms, which I specify as a comma separated list. I want to replicate the display in Luke as seen here: http://ayende.com/Blog/archive/2009/05/03/nhibernate-search-again.aspx But my index value just shows as a single field with the comma separate list value. For example: Tags term,anotherterm When I search my index, it will return results if I search with "term" but will not return anything if I search with "anotherterm" I thought the indexing process would break the comma separate list apart into separate values but this does not seem to be the case. Anyone got any ideas? Thanks

  • How to overcome Local Group Policy Editor's 1023 character limit?

    - by Louis
    I want to reorder the SSL Cipher Suite Order applied as part of KB2919355, prioritizing the forward secrecy suites above all else. Trying to do this with gpedit at Computer Configuration Administrative Templates Network SSL Configuration Settings SSL Cipher Suite Order is a problem because the new list goes over the tool's character limit. Is there anyway to overcome this limit so I don't have to keep the current priority or omit something from the list?

  • GAE/Django Templates (0.96) filters to get LENGTH of GqlQuery and filter it

    - by Halst
    I pass the query with comments to my template: COMM = CommentModel.gql("ORDER BY created") doRender(self,CP.template,{'CP':CP,'COMM':COMM, 'authorize':authorize()}) And I want to output the number of comments as a result, and I try to do things like that: <a href="...">{{ COMM|length }} comments</a> Thats does not work (yeah, since COMM is GqlQuery, not a list). What can I do with that? Is there a way to convert GqlQuery to list or is there another solution? (first question) Second question is, how to filter this list in template? Is there a construct like this: <a href="...">{{ COMM|where(reference=smth)|length }} comments</a> so that I can get not only the number of all comments, but only comments with certain db.ReferenceProperty() property, for example. Last question: is it weird to do such things using templates?

  • java serial I/O: handling USB serial connection/disconnection in a robust manner

    - by Jason S
    I'm using rxtx for serial I/O handling in Java with an FTDI2232H that provides a USB comm port. It works great, with one exception: if I unplug the USB cable, so that the COM port disappears at runtime, it spews exceptions left and right: java.io.IOException: No error in nativeavailable at gnu.io.RXTXPort.nativeavailable(Native Method) at gnu.io.RXTXPort$SerialInputStream.read(RXTXPort.java:1427) at gnu.io.RXTXPort$SerialInputStream.read(RXTXPort.java:1339) and when I re-plug the cable in again, it does not recover. Is there any way to get rxtx to work properly with USB comm port connection/disconnection? (I've tried to post to the rxtx mailing list but for some strange reason I cannot send messages even though I am subscribed to the list. I've emailed the list admin and have gotten no response.) If not, is there another serial I/O framework that does?

  • Why Html.DropDownListFor requires extra cast?

    - by dcompiled
    In my controller I create a list of SelectListItems and store this in the ViewData. When I read the ViewData in my View it gives me an error about incorrect types. If I manually cast the types it works but seems like this should happen automatically. Can someone explain? Controller: enum TitleEnum { Mr, Ms, Mrs, Dr }; var titles = new List<SelectListItem>(); foreach(var t in Enum.GetValues(typeof(TitleEnum))) titles.Add(new SelectListItem() { Value = t.ToString(), Text = t.ToString() }); ViewData["TitleList"] = titles; View: // Doesn't work Html.DropDownListFor(x => x.Title, ViewData["TitleList"]) // This Works Html.DropDownListFor(x => x.Title, (List<SelectListItem>) ViewData["TitleList"])

  • Lambda Contains in SimpleRepository.Find

    In SubSonic 3.04's SimpleRepository, I cannot seem to perform a Contains operation within a lambda expression. Here's a trivial example: SimpleRepository repo = new SimpleRepository("ConnectionString"); List<int> userIds = new List<int>(); userIds.Add(1); userIds.Add(3); List<User> users = repo.Find<User>(x => userIds.Contains(x.Id)).ToList(); I get the error message: variable 'x' of type 'User' referenced from scope '', but it is not defined Am I missing something here, or does SubSonic not support Contains in lambda expressions? If not, how would this be done?

  • RDLC - Adding a Data Source in VS2010

    - by Kezzer
    Greetings. I have an RDLC file and am wanting to add a data source to it, although without any luck so far. The data source is a custom class written by myself (just to add, we do this all the time). We recently converted over to the VS2010 RDLC format which caused some problems, but we've made some changes to our implementation that workaround the more major issues. So, back to the issue at hand, when I attempt to add my data source to the DummyDataSource list in the RDLC view in VS2010 it just does nothing, however it does add the data source to the list of data sources, but you can't select it from the drop-down list in the RDLC view which means I can't add the data source at all. Has anyone come across this problem? Is there anything I need to check? I've searched with fervour and had no luck.

  • JavaScriptSerializer with custom Type

    - by balint
    Hi, I have a function with a List return type. I'm using this in a JSON-enabled WebService like: [WebMethod(EnableSession = true)] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public List<Product> GetProducts(string dummy) /* without a parameter, it will not go through */ { return new x.GetProducts(); } this returns: {"d":[{"__type":"Product","Id":"2316","Name":"Big Something ","Price":"3000","Quantity":"5"}]} I need to use this code in a simple aspx file too, so I created a JavaScriptSerializer: JavaScriptSerializer js = new JavaScriptSerializer(); StringBuilder sb = new StringBuilder(); List<Product> products = base.GetProducts(); js.RegisterConverters(new JavaScriptConverter[] { new ProductConverter() }); js.Serialize(products, sb); string _jsonShopbasket = sb.ToString(); but it returns without a type: [{"Id":"2316","Name":"Big One ","Price":"3000","Quantity":"5"}] Does anyone have any clue how to get the second Serialization work like the first? Thanks!

  • OS X: Finder error -36 when using SMB shares on a Samba server bound to AD

    - by Frenchie
    We're looking at deploying SMB homes on Debian (5.0.3) for our mac clients rather than purchasing four new Xserves. We've got our test servers built and functioning properly. Windows clients behave perfectly, but we've run into an issue with OS X (10.6.x and 10.5.x). We're going this route instead of Windows file servers due to a whole bunch of other issues that arise when going that way. Specifically, when mounting a SMB share with unix extensions switched on and the remote server bound to AD, the finder cannot save files on the share, instead touching the file and then bombing out with a -36 IO error, folder creation is fine. Copying files in the terminal behaves fine and the problem seems to be limited to the finder. The issue arises (I think) as the remote UID/GID is passed across when using unix extensions. OS X uses its own winbind idmap (odsam) to work out the effective UID/GID from AD users and groups whilst we're using a rid map on the server. Consequently, there is a mismatch in ownership which the finder chooses to honour. How OS X appears to handle this is to use the remote uid and gid at the file permission level (see below) and then set an OS X acl granting the local uid/gid to have the appropriate permissions on the file. I think the finder touches the file (which the kernel allows because of the ACL) and then checks the filesystem perms and drops out with the IO error.
