  • xslt and xpath: match preceding comments

    - by miasbeck
    given this xml: <root> <list> <!-- foo's comment --> <item name="foo" /> <item name="bar" /> <!-- another foo's comment --> <item name="another foo" /> </list> </root> I'd like to use a XPath to select all item-nodes that have a comment immediately preceding them, that is I like to select the "foo" and "another foo" items, but not the "bar" item. I already fiddled about the preceding-sibling axis and the comment() function but to no avail.

  • Forcing LINQ to SQL to make one single call for all child rows

    - by zaph0d
    Let say I have a method (example taken from another post): public IQueryable<CityBlock> GetCityBlocks(){ var results = from o in db.city_blocks let buildings = GetBuildingsOnBlock(o.block_id) //returns Iqueryable select new CityBlock { BuildingsOnBlock = buildings, BlockOwner = o.block_owner }; return results; } In the calling method I add Skip() and Take() methods plus some filtering and then do a ToList(). The trouble is that I am getting dozens of database calls - one for all the city blocks and then a separate one for each building. Is there a way that I can refactor this code to just make two calls: one for the city blocks and one for all the buildings

  • How to make a div expand vertically to wrpa the content within it?

    - by MalcomTucker
    I have a div which wraps a number of images that are generated dynamically. I don't know how high the list of images is. My problem is the div that contains the dynamically generated images doesn't behave like it is housing any content - I want it to extend to the height of the list of images. Each image is itself wrapped in a div. This is the wrapper div: .block { padding:10px; margin-top:10px; height:auto; background-color:#f9f9f9; } This is the markup dynamically generated for (one of) the images: <div class="block"> <div style="float: left; padding: 2px 2px 2px 2px;"><IMG SRC="45.jpg" BORDER="0"/></div> ..... How do I get the block div to extend down with the images? Thanks

  • Pretty-print HTML via PHP without validation?

    - by brianjcohen
    I'd like to automatically pretty-print (indentation, mostly) the HTML output that my PHP scripts generate. I've been messing with Tidy, but have found that in its efforts to validate and clean my code, Tidy is changing way too much. I know Tidy's intentions are good but I'm really just looking for an HTML beautifier. Is there a simpler library out there that can run in PHP and just do the pretty-printing? Or, is there a way to configure Tidy to skip all the validation stuff and just beautify?

  • Android Contact Picker

    - by user1066398
    I was wondering: Is it possible to customize the Android Contact Picker so that it can also allow adding a new contact as a menu option in the default contact list? At the moment, if I invoke the contact picker from my activity, it only displays the default contact list. I would also like the user to be able to create a new contact if it did not exist already. I have searched this quite a lot but do not find appropriate API to do this. There is nothing in ContactContract as far as I can see.

  • Sorting an NSArray of NSString

    - by Robert Eisinger
    Can someone please show me the code for sorting an NSMutableArray? I have the following NSMutableArray: NSMutableArray *arr = [[NSMutableArray alloc] init]; with elements such as "2", "4", "5", "1", "9", etc which are all NSString. I'd like to sort the list in descending order so that the largest valued integer is highest in the list (index 0). I tried the following: [arr sortUsingSelector:@selector(compare:)]; but it did not seem to sort my values properly. Can someone show me code for properly doing what I am trying to accomplish? Thanks!

    I'm new to java and I wonder if there is simple way to know flow like the following of object creation, I'm using eclipse and when I write new ObjectInputStream and press CTRL+SPACE. I don't see any option that I can enter new BufferedInputStream (I have copied the code from example) and than to create new object for FileInputStream etc. in = new ObjectInputStream(new BufferedInputStream(new FileInputStream("emp.dat"))); List temp = (List)in.readObject(); I give that example since this is the first time that I saw this kind of creation new object flow and I want to use some best practice for the next times.

  • trying to set a dropdown in MVC

    - by RJ
    I almost have this solved but need a little push. Here's what I have: In the database I have a field called active that is a bit field (True/False) I have placed a dropdownlist on the View form like this: <%= Html.DropDownList("lstActive", new SelectList((IEnumerable)ViewData["ActiveList"])) %> In my controller, I simply have this code to generate the True/False in the dropdown: List<string> activeList = new List<string>(); activeList.Add("True"); activeList.Add("False"); ViewData["ActiveList"] = new SelectList(activeList); I want to bind to the field in the database called active and select it in the dropdown. When I view it like this I get this: So the questions are these: Obviously I am not pointing to the Value and Text property but what is that in this case? And how do I select the value that is in the database? Any help would be appreciated.

  • How to improve the speed of a loop containing a sqlalchemy query statement as conditional

    - by LtPinback
    This loop checks if a record is in the sqlite database and builds a list of dictionaries for those records that are missing and then executes a multiple insert statement with the list. This works but it is very slow (at least i think it is slow) as it takes 5 minutes to loop over 3500 queries. I am a complete newbie in python, sqlite and sqlalchemy so I wonder if there is a faster way of doing this. list_dict = [] session = Session() for data in data_list: if session.query(Class_object).filter(Class_object.column_name_01 == data[2]).filter(Class_object.column_name_00 == an_id).count() == 0: list_dict.append({'column_name_00':a_id, 'column_name_01':data[2]}) conn = engine.connect() conn.execute(prices.insert(),list_dict) conn.close() session.close() edit: I moved session = Session() outside the loop. Did not make a difference.

  • Is C# compiler not reporting all errors at once at each compile?

    - by Joan Venge
    When I am compiling this project, it show like 400+ errors in the Error List window, then I go to error sites, fix some, and the number goes to say 120+ errors, and then after fixing some more, the next compile reports like 400+ again. I can see that different files are coming in in the Error List window, so I am thinking the compiler aborts after a certain number of errors? If so, what's the reason for this? Is it not supposed to gather all the errors that are present in the project even if they are over 10K+?

  • Do I have to hash twice in C#?

    - by Joe H
    I have code like the following: class MyClass { string Name; int NewInfo; } List<MyClass> newInfo = .... // initialize list with some values Dictionary<string, int> myDict = .... // initialize dictionary with some values foreach(var item in newInfo) { if(myDict.ContainsKey(item.Name)) // 'A' I hash the first time here myDict[item.Name] += item.NewInfo // 'B' I hash the second (and third?) time here else myDict.Add(item.Name, item.NewInfo); } Is there any way to avoid doing two lookups in the Dictionary -- the first time to see if contains an entry, and the second time to update the value? There may even be two hash lookups on line 'B' -- one to get the int value and another to update it.

  • SQL change "like" to "contains"

    - by Paul
    products table (mySQL) record_id categories (comma-delimited list) --------- -------------------------------- 1 960|1,957|1,958|1 I have the following dynamic query (simplified for the purposes of this question). The query is passed specified categories, each in the format xxxx|yyyy, and I need to return products having the passed category in its comma-delimited list of categories. The current query looks like: select p.* from products p where (p.categories like '%27|0%' or p.categories like '%972|1%' or p.categories like '%969|1%') But, the LIKE clause sometimes permits anomalies. I would like to write the query more like: select p.* from products p where (p.categories contains '27|0' or p.categories contains'972|1' or p.categories contains '969|1') How would I do this?

  • What's the best way to handle modules that use each other?

    - by Axeman
    What's the best way to handle modules that use each other? Let's say I have a module which has functions for hashes: # Really::Useful::Functions::On::Hash.pm use base qw<Exporter>; use strict; use warnings; use Really::Useful::Functions::On::List qw<transform_list>; our @EXPORT_OK = qw<transform_hash transform_hash_as_list ...>; #... sub transform_hash { ... } #... sub transform_hash_as_list { return transform_list( %{ shift() } ); } #... 1 And another module has been segmented out for lists: # Really::Useful::Functions::On::List.pm use base qw<Exporter>; use strict; use warnings; use Really::Useful::Functions::On::Hash qw<transform_hash>; our @EXPORT_OK = qw<transform_list some_func ...>; #... sub transform_list { ... } #... sub some_func { my %params = transform_hash @_; #... } #... 1 Suppose that enough of these utility functions are handy enough that I'll want to use them in BEGIN statements and import functions to process parameter lists or configuration data. I have been putting sub definitions into BEGIN blocks to make sure they are ready to use whenever somebody includes the module. But I have gotten into hairy race conditions where a definition is not completed in a BEGIN block. I put evolving code idioms into modules so that I can reuse any idiom I find myself coding over and over again. For instance: sub list_if { my $condition = shift; return unless $condition; my $more_args = scalar @_; my $arg_list = @_ > 1 ? \@_ : @_ ? shift : $condition; if (( reftype( $arg_list ) || '' ) eq 'ARRAY' ) { return wantarray ? @$arg_list : $arg_list; } elsif ( $more_args ) { return $arg_list; } return; } captures two idioms that I'm kind of tired of typing: @{ func_I_hope_returns_a_listref() || [] } and ( $condition ? LIST : ()) The more I define functions in BEGIN blocks, the more likely I'll use these idiom bricks to express the logic the more likely that bricks are needed in BEGIN blocks. Do people have standard ways of dealing with this sort of language-idiom-brick model? I've been doing mostly Pure-Perl; will XS alleviate some of this?

  • How to make image's background transparency to 0?

    There are images displayed inside a HTML table in a PHP code : The code of this table is : for ($i = 0; $i < $data['list']['cnt']; $i++) { $tabRows[$i][1]['width'] = "45%"; $tabRows[$i][1]['align'] = "center"; $tabRows[$i][1]['value'] = '<img src="'.HTTP_FIGURES.$data['list'][$i]['fig_image'].'" />'; } As you can see the background of the images are seen and they make the page dirty. So I want to remove the background of each image. How to do that ?

  • MySQL does not work on localhost without Local Area Connection

    - by user985171
    I use WampServer(Apache, PHP, MySQL) and have no problems when some kind of network adapter(wireless or lan) is connected(i-e Local Area Connection has status connected) 'even if i am not connected to the internet'(for example when i am connected to the router but that is not connected to the internet). When there is no network connection, i get a php error like MySQL could not connect to 127.0.0.1 on port 3306. Interestingly, 'telnet 127.0.0.1 3306' says that it could not connect to the port, even when the server and MySQL are running fine(i-e when some kind of local area connection is connected). So i turned off all kinds of firewall(antivirus and windows) but still no difference in anything. And that is why this issue is quite puzzling. Things i have already tried(will update this list along the way):- -The skip-networking directive in my.ini.

  • how to avoid repeating code?

    - by helloWorld
    I have some technical question, I have repeating code in my work, and I want to get rid of it, so I know that in C++ it is not good idea to use macro, but instead I must use inline function, is it good idea to use this function as inline: list<Data>::iterator foo(int data){ if(dataExists(data)){ list<Data>::iterator i; for(i = Data.begin(); i != Data.end(); ++i){ if(i->getData() == data){ break; } return i; //here I have one more problem, what can I return if data doesn't exist? } I'm beginner, and I think that this function is very unsafe, can somebody please give me advice, how can I improve my code, thanks in advance P.S. what usually do You use to avoid repeating code?

  • setting value to a parameter - always saying that it is null REALLY NEED INPUT

    - by Amina
    So I have this schedule visit page with two groups. Group 1 contains a list of: Cases. Group 2 contains a list of: Parties. each group has a checkboxes next to its item for the user to select. My Issue when i select a case and/or a party and save -- then go to the edit page of the visit i just saved and only my selected case is checked and the party i selected is not checked. After debugging i realized that the partyId is not being saved properly during the create page and thus not showing as selected or saved on the edit page. I really need help on how to properly save the party selected and setting for it a value from the parameter. Here is my code of what i have for saving a case and would like to know how to properly save with party. Controller [HttpPost] [ValidateInput(false)] public ActionResult Create(VisitViewModel viewModel, Guid[] associatedCasesSelected, Guid[] selectedParties) { if (!ModelState.IsValid) { viewModel.Time = _timeEntryHelper.Value; AddLookupsToViewModel(viewModel); return View(viewModel); } var visitEntry = Mapper.Map<VisitViewModel, VisitEntry>(viewModel); ... viewModel.CasePartyIds = selectedParties; try { _visitEntryService.Create(visitEntry, associatedCasesSelected); this.FlashInfo(string.Format(Message.ConfirmationMessageCreate, Resources.Entities.Visit.EntityName)); } catch (RulesException ex) { ex.CopyTo(ModelState); } if (ModelState.IsValid) return RedirectToAction("Edit", "Case", new { caseId = viewModel.CaseId }); AddLookupsToViewModel(viewModel); return View(viewModel); } VisitEntryService public void Create(VisitEntry visitEntry,IList<Guid>caseIds) { EnsureValid(visitEntry); _visitEntryRepository.Save(visitEntry); caseIds = AddCurrentCaseToCases(visitEntry.CaseId, caseIds); foreach (var caseId in caseIds.Distinct()) { var visit = new Visit {CaseId = caseId, VisitEntryId = visitEntry.VisitEntryId}; _visitService.Create(visit); } } AddCurrentCaseToCases private static IList<Guid>AddCurrentCaseToCases(Guid caseId, IEnumerable<Guid>caseIds) { var cases = new List<Guid>(); if (caseIds != null) { cases.AddRange(caseIds); if(!caseIds.Contains(caseId)) cases.Add(caseId); } else cases.Add(caseId); return cases; } VisitService public Visit Get(Guid visitId) { return DataContext.Visits.SingleOrDefault(v => v.VisitId == visitId); } public void Save(Visit visit) { if(visit.VisitId == Guid.Empty) { visit.VisitId = Guid.NewGuid(); DataContext.Visits.InsertOnSubmit(visit); } else { var currentVisit = Get(visit.VisitId); if (currentVisit == null) throw RepositoryExceptionFactory.Create("Visit", "VisitId"); } DataContext.SubmitChanges(); } Any TIPS or IDEAS is greatly appreciated at this time :) The entitiy for the parties will be VisitEntryParty
