• Sending JSON collection to ASMX webservice

  - by Mironline

  I have got this json collection in page : var json= { "Elements": [ {"Alignment":null,"Bold":false}, {"Alignment":null,"Bold":false} ], "Front":true, "ThemeID":"9" }; I've generated this JSON in run-time & posted to page. my question is , What is the best solution to send this json to web-service using jQuery. should I use the JSON.stringify method and sent it as as string ? if yes what is the input type in web-service ? can I send it as an object to web-service and set the List<CusomeObject> as input ? in this case how can I implement that ?

• 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 ?

• Sharepoint 2010 - AAM - SPSite(SPContext.Current.Site.ID) RootWeb.Url is from wrong zone

  - by user2026343

  I have a sharepoint 2010 web application with 2 different zones, default zone with windows login (for search crawl), internet with Claims (FBA) for users to login. I have custom webparts that uses using (SPSite mySite = new SPSite(SPContext.Current.Site.ID)) using (SPWeb web = mySite.RootWeb) { string url = web.Url I use this url to include to emails etc... Problem is: when user connects to FBA (extended zone), and goes to the webpart,string url in my code returns the url of the default zone(windows auth) where user should not be touching. I have different host headers for these zones, any help would be very appreciated. Update: fixed it with using (SPSite newsite =new SPSite(SPContext.Current.Site.ID,SPContext.Current.Site.Zone)) using (SPWeb web = newsite.RootWeb) { //do your implementation here }

• C# Async call garbage collection

  - by Troy

  Hello. I am working on a Silverlight/WCF application and of course have numerous async calls throughout the Silverlight program. I was wondering on how is the best way to handle the creation of the client classes and subscribing. Specifically, if I subscribe to an event in a method, after it returns does it fall out of scope? internal MyClass { public void OnMyButtonClicked() { var wcfClient = new WcfClient(); wcfClient.SomeMethodFinished += OnMethodCompleted; wcfClient.SomeMethodAsync(); } private void OnMethodCompleted(object sender, EventArgs args) { //Do something with the result //After this method does the subscription to the event //fall out of scope for garbage collection? } } Will I run into problems if I call the function again and create another subscription? Thanks in advance to anyone who responds.

  Hi, I'm reflecting a property 'Blah' its Type is ICollection public ICollection<string> Blah { get; set; } private void button1_Click(object sender, RoutedEventArgs e) { var pi = GetType().GetProperty("Blah"); MessageBox.Show(pi.PropertyType.ToString()); } This gives me (as you'd expect!) ICollection<string> ... But really I want to get the collection type i.e. ICollection (rather than ICollection<string>) - does anyone know how i'd do this please?

• any way to get sharepoint groups with a given site url

  - by standley-nguyen

  Hi all. I'm getting a stuck. Suppose that I create 5 sites. For each one, I create a few sharepoint groups. So, I create a dropdownlist control to bind 5 sites and when I click on any site there, I will get sharepoint groups created on it. But I always see the dropdownlist used to bind these groups still never change. I mean it only binds a few default groups in sahrepoint everytime. The new created groups is not. And I have confusion like this web.AssociatedGroups web.Groups web.SiteGroups which one we will use this case ? Please guide me Here my snippet code private void BindSPGroupsToDropDownList(DropDownList ddl, string siteUrl) { ddl.Items.Clear(); try { SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(siteUrl)) { using (SPWeb web = site.OpenWeb()) { //web.SiteGroups foreach (SPGroup spGroup in web.Groups) { ddl.Items.Add(new ListItem(spGroup.Name.Trim(), spGroup.ID.ToString())); } } } }); } } thanks in advance

• Re-ordering collection C#

  - by Adam

  Hi - I have a problem which I cant seem to find answer to through searches (either that or I am searching for the completely wrong thing!). I have a list of items called "Top 10" in a sortedlist item that is populated from my DB (SortedList where int is position and string is item). I want to be able to move items up & down the list order at the click of a button and then save the new order back to the DB. I am OK with the DB part it is just the re-ordering I am really struggling with - is a sortedlist the correct collection for this? Many thanks for any advice offered.

• Lookup Field as a Site Column via CAML

  - by Rob Windsor

  I'm trying to create a Lookup Field as a Site Column via CAML. The list I want to use as the source of the lookup is created in the Feature Receiver so I don't know it's ID. I've read several blog posts that indicate that I can just put the path to the list in the List attribute. It seems from the comments on these post that this solution works for some people but not for others. I'm in the latter group. When I try to associate a content type that uses the lookup site column I: "Exception from HRESULT: 0x80040E07" <Field ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" StaticName="Test_x0020_Lookup_x0020_Column" DisplayName="Test Lookup Column" Type="Lookup" Required="FALSE" List="Lists/Test" ShowField="Title" PrependId="TRUE" Group="Test Site Columns" /> <ContentType ID="0x0100B6D92594DDCE8E479D0EB0C414C463B0" Name="Test Lookup Content Type" Version="0" Group="Test Content Types"> <FieldRefs> <FieldRef ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" Required="TRUE" /> </FieldRefs> </ContentType>

• C# - implementing GetEnumerator() for a collection inherited from List<string>

  - by Vojtech

  Hi, I am trying to implement FilePathCollection. Its items would be simple file names (without a path - such as "image.jpg"). Once the collection is used via foreach cycle, it should return the full path created by concatenating with "baseDirectory". How can I do that? public class FilePathCollection : List<string> { string baseDirectory; public FileCollection(string baseDirectory) { this.baseDirectory = baseDirectory; } new public System.Collections.IEnumerator GetEnumerator() { foreach (string value in this._list) //this does not work because _list is private yield return baseDirectory + value; } } Thanks in advance! :-)

• How to tell which thread(s) are producing all the garbage?

  - by Brad Hein

  I have an app with about 15 threads. Most do mundane tasks and sleep most of their lives. Others collect information and cache it in hashmaps. The hashmaps grow to a moderate size and level out. The number of keys and size of value remains constant, but the contents of the values changes (at 33 keys per second average). When I start my app, I notice the garbage collection interval goes from minutes to once per second, and the amount of garbage is 700k+ each time. In fact as I was writing this, it caused my phone to reboot with an error "Referencetable Overflow". Here's my question: Are there any tricks to identifying which threads are producing the garbage, or even finding out more about what garbage they are producing?

• Oracle data provider hangs IIS worker process when web site is stopped

  - by Greg

  We're experiencing a nasty issue in Oracle 11g Release 2 where the w3wp process takes over and entire processor core, and debugging shows that the Oracle data provider is throwing ThreadAbortExceptions infinitely. A developer found this issue by doing the following: 1) Browse a web site that uses Oracle data connections locally (http://localhost/OracleWebSite) - we use IIS, not the ASP.NET dev server, for all of our sites. This ensures that the w3wp process is running and that an active Oracle pool of connections exists in the app pool. 2) Stop the web site (or perform a Rebuild All operation in Visual Studio on the web site in question). Our Oracle connection handling in the affected applications (all Oracle web apps) is well-established and robust. This issue does not occur if we disable connection pooling. This issue does not occur in Oracle 11g Release 1.

• SSRS Dynamic Returning Dataset Collection Field in Expression

  - by Ray Clark

  I wrote a custom assembly to take a parameter value from the report and return a field from the dataset collection. My assembly returns the correct fields!name.value, but it shows me the string representation of it. How can I get it to resolve as the actual fields!name.value to display the actual data in the dataset? If I enter fields!name.value in manually it works fine showing me the value. If I resolve it with my custom code it display "fields!name.value" to me in the cell.

• Finding parents where child collection does not contain an item

  - by Colin Bowern

  I am trying to get a list of parents where the child collection does not contain an item of a specific type. The LINQ equivalent would be something like: dataset.Where(x => x.Items.FirstOrDefault(y => y.Type.Code == "ABC") == null) The object model is Parent Child (Items) Type Code If Parent is my aggregate root, how would I model this in NHibernate criteria/query? Here's my first attempt: var results = session.CreateCriteria<Parent>() .CreateCriteria("Items") .CreateCriteria("Type") .Add(Restrictions.Not(Restrictions.Eq("Code", "ABC"))) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Parent>(); This doesn't seem to return the right entities - it just returns them all.

• Hide other domains' menus from node edit form on a Drupal site using domain access

  - by monkeyninja

  I'm in the process of making some improvements to a live Drupal site that's using the Domain Access module to run a number of microsites. I'm trying to find a way of restricting the menus a user can post content to from the node edit screen. A user on one of the domains should only be able to post content to menus associated with that domain. Is there a simple way of achieving this? I'm guessing there are some hooks I could use, but so far I have been unable to identify them. I'd prefer not to have to install further modules to achieve this and to be able to add some code to the current site to alter the forms. The site is struggling with the large number of modules we've had to install on it already.

• C5 Generics Collection IntervalHeap<T> -- getting an IPriorityQueueHandle from a T for Replace or De

  - by Jared Updike

  I'm using the Generics Collection library C5 (server down :-( ) and I have an IntervalHeap(T) and I need to Delete or Replace a T that is not the Max or Min. How do I get an IPriorityQueueHandle from my T? The C5 library source code shows that IPriorityQueueHandle(T) has no methods or properties to implement and the compiler thinks my implementation of IPriorityQueueHandle(T) for my T is acceptable. I try to use a T like this: q.Replace(t, t); and the C5 library throws an InvalidCastException because it cannot convert my T to a (Handle).

• Moved X-cart site to Sub Directory - Need Help setting up Redirects

  - by Rich G

  I recently moved an x-cart site from a root directory to a sub directory, and also built a new Wordpress site under the root directory. The problem I am having is that I am trying to figure out a redorect combo that will show the search engines that the product pages are now under the sub directory (/store) but do not want the search engines to exclude the brand new site under the Root directory. I was thinking that if I could just have redirect any .html file (all of the product pages link to .html pages) that it would redirect to the same page just under the sub directory. The reason I cannot do everything one by one is because there are about 50k+ products that would need be changed. Any information and help would be greatly appreciated! Thank you in advanced!

• Using git to sync existing file collection?

  - by chrish

  I've got a collection of files that formerly lived in a Subversion repo; on my new server I've imported them into a git repo so I could start getting more experience with that. On several other machines, I've got mostly up-to-date copies of the existing svn repo files. Is there any way to sync to the new git repo, but use these existing files so I don't have to re-transfer all of the data? Is git smart enough that if I do a fetch? or checkout? that it'll notice the files are identical and not re-transfer them?

• Empty dict-like collection problem in SQLAlchemy

  - by maksymko

  I have a mapping in SQLAlchemy that looks like this: t_property_value = sa.Table('property_value', MetaData, autoload = True, autoload_with = engine) orm.mapper(PropertyValue, t_property_value) t_estate = sa.Table('estate', MetaData, autoload = True, autoload_with = engine) orm.mapper(Estate, t_estate, properties = dict( property_hash = orm.relation(PropertyValue, collection_class = column_mapped_collection(t_property_value.c.property_id)) )) Now, everything seems to be fine, when I load the Estate object and it has some relations to PropertyValue objects. However, when it does not, then property_hash attribute is None, instead of being something dict-like, so I can not add new relations like this: estate.property_hash[prop_id] = PropertyValue(...) because I get the "'NoneType' object does not support item assignment" error. So, is there any way to force SQLAlchemy to create proper empty collection?

• Django i18n: makemessages only on site level possible?

  - by AndiDog

  I have several strings in my site that don't belong to any app, for example {% block title %}{% trans "Login" %}{% endblock %} or a modified authentication form used to set the locale cookie class AuthenticationFormWithLocaleOption(AuthenticationForm): locale = forms.ChoiceField(choices = settings.LANGUAGES, required = False, initial = preselectedLocale, label = _("Locale/language")) Now when I execute django-admin.py makemessages --all -e .html,.template in the site directory, it extracts the strings from all Python, .html and .template files, including those in my apps. That is because I develop my apps inside that directory: Directory structure: sitename myapp1 myapp2 Is there any way to extract all strings that are not in my apps? The only solution I found is to move the app directories outside the site directory structure, but I'm using bzr-externals (similar to git submodules or svn externals) so that doesn't make sense in my case. Moving stuff that needs translation into a new app is also possible but I don't know if that is the only reasonable solution.

• how to "lock" live site when doing (phing) deployment

  - by Jorre

  On http://www.slideshare.net/eljefe/automated-deployment-with-phing in slide 15 they are talking about "locking the live site" when doing deployment. We are running multiple webshops in a SAAS application where it is possible that users are adding products, buying products and paying for products online, and so on... When deploying we want to do this as clean as possible, so that not payments or orders or other critical data will be lost. We have a deployment scenario set up using phing (amazing tool!) but we are missing one crucial step being the "locking of the live site" while deploying. What is a possible way to lock a live site and bring it back online after deploying?

• Pre-cache site as user visits

  - by strager

  I am making a static site which is 'forced' to be cached via Cache-control, etc. When a user visits my site, I want the browser to crawl my site, caching pages, so when the user navigates to a page, the load is almost instant. (I do not need a recursive crawl, as that will probably happen as the user navigates between pages. I just need to crawl the links on the current page, and of course not re-caching a page which has already been cached.) (Also, I am not changing pages using Ajax-like techniques. These are essentially normal flat HTML files with normal links.) How can I do this pre-caching using Javascript? (I am using jQuery.)

• unable to add objects to saved collection in GAE

  - by Jeffrey Chee

  I have a ClassA containing an ArrayList of another ClassB I can save a new instance of ClassA with ClassB instances also saved using JDO. However, When I retrieve the instance of Class A, I try to do like the below: ClassA instance = PMF.get().getPersistenceManager().GetObjectByID( someid ); instance.GetClassBArrayList().add( new ClassB(...) ); I get an Exception like the below: Uncaught exception from servlet com.google.appengine.api.datastore.DatastoreNeedIndexException: no matching index found.. So I was wondering, Is it possible to add a new item to the previously saved collection? Or was it something I missed out. Best Regards

• Re-ordering a collection of UIView's based on their CGPoint

  - by Chris

  Hi all, I have a NSMutableArray that holds a collection of UIViewControllers Amongst other properties and methods an instance of each of the viewControllers are placed in a parent view The user will place these objects individually when desired to. So essentially I use - (void)addSubview:(UIView *)view when a new view is added to the parent view controller. Because the UI is isometric it's made things a tad more complicated What I am trying to do is re-order the views based on their co-ordinate position, so items higher up the parent UIView frame is indexed lower then views lower in the parent UIview frame. And items that are on the left side of the view are positioned at a higher index to those on the right I think the solution may have to do with re-ordering the NSMutableArray but how can I compare the CGpoints? Do I need to compare the x and y separately?

• Consolidating data in SharePoint from different sites based on variable site naming

  - by Mughrabi

  Hi, am working on a project where I want to pull data from different lists in SharePoint and have these data imported into a single list. The list has the same attribute everywhere; it is located in different sites. I have a list which contains all the site names and URL to those sites. The idea is to read from this list all the site names and then go to each one of those sites and try and pull the information from the list under that particular site, in synchronies matter. Data that are pulled from last week’s process do not need to be pulled again. Can someone guide me in explaining what would be the best way to doing this solution? Am using SharePoint 2007
