• How to bind data in silverlight? In case I don't know which columns would be retrieved from database

  - by kwon

  I am trying to bind data from database to datagrid in silverlight. When I get typed data from DB, it is no problem since I use List<'EntityObject' collection object for example. However, sometimes I need data which I won't be able to know how many and what columns will be generated in design time. In this case, I cannot use typed collection like List<'EntityObject'. In addition, it is not able to use DataSet in silverlight. So, in this case and situation, how to solve this kind of problem? Thanks in advance Kwon

• 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?

• 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!

• 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.

• 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?

• How do you check individual SqlCommands ran during a SqlTransactions to see if they will run?

  - by Sam F

  I've been reading up on SqlTransactions and have found a great load of examples like: http://www.devhood.com/tutorials/tutorial_details.aspx?tutorial_id=451 The problem is, when I do a BeginTransaction() (Execute all the commands) and then Commit() at the end all the commands I execute get run and the ones with syntax errors or other errors just get skipped. This is where I would also like to run a roll back, not skip over them. I found a few articles on the subject but they were not very helpful and purely in SQL. Is there any way to find out if one of the ExecuteNonQuery()'s failed before the commit and not just skipped? Thanks.

• Highlight row of form when input is focussed

  - by Jeepstone

  I have the following piece of Mootools 1.11 code (not upgradable as this is within Joomla), which I want to highlight the form row, when an item within it is focussed. However, this doesn't work. I need to know how to access the parent div of the form item. window.addEvent('domready', function() { var list = $$('#ChronoContact_lensorder div.formrow'); list.each(function(element) { var fx = new Fx.Styles(element, {duration:200, wait:false}); element.addEvent('focus', function(){ fx.start({ 'background-color': '#e6f0f2', color: '#FFF' }); }); element.addEvent('focus', function(){ fx.start({ 'background-color': '#FFF', 'color': '#2F9AD0' }); }); }); }); HTML is: <div class="formrow"> <label for="ud">Uncut Diameter:</label> <input type="text" id="ud" name="ud" /> </div> 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?

• [Seamless Handover of WiFi] Can we program to automatically join the WiFi with the most strongest si

  - by Dobby

  Hi all, I am making a iphone program, I wish that: it can sense and display the current signals of wifi, with strength, - as I checked, this cannot be done by official SDK, but there were some private library that can handle. 2. i wish it can always automatically join the best wifi with the most highest strength ( assume that all wifi APs have no password, and all are not remembered into the used-list inside iphone), which is something like "seamless handover"... I just guess that, there should be some APIs to let the system join one designated wifi signal from the list, and wish someone could help me. I would like to appreciate a lot : ) Thanks a lot!

• custom Filter Android won't show me the results

  - by TiGer

  Hi, I have been implementing a class which class extends ArrayAdapter and implements Filterable. The filtering part (in the performFiltering method()) seems to go ok, it fills the FilterResults object just as expected. But then I think I'm not doing it right on how to publish the results, atm I have : protected void publishResults(CharSequence prefix, FilterResults results) { // NOTE: this function is *always* called from the UI thread. subItems = (Vector)results.values; notifyDataSetChanged(); } But this simply won't "populate" my List with the received data. So now my question is how do I populate my List with the received results ? Do I have to do that programmatically ?

• 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.

• Select next element in the page source using jQuery

  - by Travis

  I have an arbitrarily deep list of the form: <ul> <li></li> <li> <ul> <li></li> </ul> </li> </ul> I am trying to build a function "nextElement" that returns a jQuery selector. The first time the function is called, it returns the first li in the list. The second time it is called, it returns the next li in the page. Etc. I'd like this function to pay no attention to siblings, parents, children, etc. All I care about is that everytime it is called, the next li in the source gets chosen. Any suggestions on how to go about approaching this? Thanks

• 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?

Also, what would be the best method to simply grab a new time from the server when it is updated without having to pull the whole list again? Thanks!

• Understanding flow of object creation

  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.

• jQuery cookie behaves differently on local machine vs production server

  - by user1810414

  I'm setting a jQuery cookie for some site javascript effects. I'm setting expiration date to 30 days. On local development machine cookie expiration is set properly, whereas on production expiration is being set to end of session. After inspecting the created cookies with web develoer tools, everything is identical except production machine cookie is marked as "session cookie" and setting expiration is disallowed, while cookie created on local development machine is not set to "session" and expiration date is editable. Is there a way to make production machine cookie accept the expiration date? This is how I set the cookie: $.cookie('skip_animation','skip', 2592000); Using jQuery 1.6.4 (legacy site) All browsers behave the same way
