  • Facebook - generating fb tag in Jquery - not working

    - by Gublooo
    Hey guys Kind of stuck here - I have this functionality on my site where I display 10 user comments along with their photo and when a user clicks on "More" - using Jquery more results are fetched from DB and the results are displayed via string generated in the Jquery method. This is a shortened version of my Jquery function $(".more_swipes").live('click',function() { var profile_id = 'profile-user_id; ?'; $.getJSON("/profile/more-swipes", { user_id: profile_id},function(swipes) { $.each(swipes, function(i,data){ newcomment="<div"; newcomment +="<fb:profile-pic uid='"+data.fb_userid+"' linked='false'/"; newcomment +="Name="+data.user_name+"-Comment="+data.comment; $("#moreswipes").append(newcomment); }); }); return false; }); Here as you can see I'm using the tag <fb:profile-pic uid='"+data.fb_userid+"' linked='false'/ Now when more results get displayed, the profile pic of the user is not getting displayed - when I look at the source code - this is how the fb tag looks when its generated thru Jquery <fb:profile-pic uid="222222" linked="false" height="50" width="50" Whereas the FB tags not generated thru the Jquery code look like <fb:profile-pic uid="222222" linked="false" height="50" width="50" class="FB_profile_pic <fb_profile_pic_rendered FB_ElementReady" style="width:px;height:50px" <img src="http://profile.atk......2025.jpg" alt="User Name" title="User Name" style="width:px;height:50px" class="FB_profile_pic"/ </fb:profile-pic So when I add it as a String in JQuery function - facebook is not identifying it and executing it Any idea how to fix this Thanks a bunch

  • In jQuery datepicker beforeShowDay if fails

    - by michalzuber
    HI. I'm having problem to highlight more days. Somehow the if statement in beforeShowDay isn't true when it should be :( dateString typeof is string and an example is available in the screenshot at http://mikaelz.host.sk/datepicker.png Pasted code: var dates = new Array(); function addDate(date) {if (jQuery.inArray(date, dates) < 0) dates.push(date);} function removeDate(index) {dates.splice(index, 1);} function addOrRemoveDate(date) { var index = jQuery.inArray(date, dates); if (index >= 0) removeDate(index); else addDate(date); } function padNumber(number) { var ret = new String(number); if (ret.length == 1) ret = "0" + ret; return ret; } jQuery(document).ready(function(){ jQuery("#pick-date").datepicker({ onSelect: function(dateText, inst) { addOrRemoveDate(dateText); }, beforeShowDay: function (date){ var year = date.getFullYear(); var month = padNumber(date.getMonth()); var day = padNumber(date.getDate()); var dateString = day + "." + month + "." + year; if (dates.indexOf(dateString) >= 0) { return [true,"ui-state-highlight"]; } return [true, ""]; } }); }); Big thanks for any good ideas what could be wrong.

  • ASP.MVC 2 Model Data Persistance

    - by toccig
    I'm and MVC1 programmer, new to the MVC2. The data will not persist to the database in an edit scenario. Create works fine. Controller: // // POST: /Attendee/Edit/5 [Authorize(Roles = "Admin")] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Attendee attendee) { if (ModelState.IsValid) { UpdateModel(attendee, "Attendee"); repository.Save(); return RedirectToAction("Details", attendee); } else { return View(attendee); } } Model: [MetadataType(typeof(Attendee_Validation))] public partial class Attendee { } public class Attendee_Validation { [HiddenInput(DisplayValue = false)] public int attendee_id { get; set; } [HiddenInput(DisplayValue = false)] public int attendee_pin { get; set; } [Required(ErrorMessage = "* required")] [StringLength(50, ErrorMessage = "* Must be under 50 characters")] public string attendee_fname { get; set; } [StringLength(50, ErrorMessage = "* Must be under 50 characters")] public string attendee_mname { get; set; } } I tried to add [Bind(Exclude="attendee_id")] above the Class declaration, but then the value of the attendee_id attribute is set to '0'. View (Strongly-Typed): <% using (Html.BeginForm()) {%> ... <%=Html.Hidden("attendee_id", Model.attendee_id) %> ... <%=Html.SubmitButton("btnSubmit", "Save") %> <% } %> Basically, the repository.Save(); function seems to do nothing. I imagine it has something to do with a primary key constraint violation. But I'm not getting any errors from SQL Server. The application appears to runs fine, but the data is never persisted to the Database.

  • Facebook Android SDK. Error validating access token

    - by Mj1992
    I am trying to access user information from facebook sdk.But I keep getting this error. {"error":{"message":"Error validating access token: The session has been invalidated because the user has changed the password.","type":"OAuthException","code":190,"error_subcode":460}} Here is the call which returns me the error in the response parameter of the oncomplete function. mAsyncRunner.request("me", new RequestListener() { @Override public void onComplete(String response, Object state) { Log.d("Profile", response); String json = response; //<-- error in response try { JSONObject profile = new JSONObject(json); MainActivity.this.userid = profile.getString("id"); new GetUserProfilePic().execute(); runOnUiThread(new Runnable() { @Override public void run() { Toast.makeText(getApplicationContext(), "Name: " + MainActivity.this.userid, Toast.LENGTH_LONG).show(); } }); } catch (JSONException e) { e.printStackTrace(); Log.e("jsonexception",e.getMessage()); facebook.extendAccessTokenIfNeeded(MainActivity.this, null); GetUserInfo(); } } @Override public void onIOException(IOException e, Object state) { } @Override public void onFileNotFoundException(FileNotFoundException e, Object state) { } @Override public void onMalformedURLException(MalformedURLException e, Object state) { } @Override public void onFacebookError(FacebookError e, Object state) { } }); Sometimes I get the correct response also.I think this is due to the access token expiration if I am right. So can you guys tell me how to extend the access token although I've used this facebook.extendAccessTokenIfNeeded(this, null); in the onResume method of the activity. How to solve this?

  • Android Java writing text file to sd card

    - by Paul
    I have a strange problem I've come across. My app can write a simple textfile to SD card and sometimes it works for some people but not for others and I have no idea why. Some people it force closes if they put some characters like "..." in it and such. I cannot seem to reproduce it as I've had no troubles but this is the code that handles it. Can anyone think of something that may lead to problems or a better to way to do it? public void generateNoteOnSD(String sFileName, String sBody){ try { File root = new File(Environment.getExternalStorageDirectory(), "Notes"); if (!root.exists()) { root.mkdirs(); } File gpxfile = new File(root, sFileName); FileWriter writer = new FileWriter(gpxfile); writer.append(sBody); writer.flush(); writer.close(); Toast.makeText(this, "Saved", Toast.LENGTH_SHORT).show(); } catch(IOException e) { e.printStackTrace(); importError = e.getMessage(); iError(); } }

  • Bruteforcing Blackberry PersistentStore?

    - by Haoest
    Hello, I am experimenting with Blackberry's Persistent Store, but I have gotten nowhere so far, which is good, I guess. So I have written a a short program that attempts iterator through 0 to a specific upper bound to search for persisted objects. Blackberry seems to intentionally slow the loop. Check this out: String result = "result: \n"; int ub = 3000; Date start = Calendar.getInstance().getTime(); for(int i=0; i<ub; i++){ PersistentObject o = PersistentStore.getPersistentObject(i); if (o.getContents() != null){ result += (String) o.getContents() + "\n"; } } result += "end result\n"; result += "from 0 to " + ub + " took " + (Calendar.getInstance().getTime().getTime() - start.getTime()) / 1000 + " seconds"; From 0 to 3000 took 20 seconds. Is this enough to conclude that brute-forcing is not a practical method to breach the Blackberry? In general, how secure is BB Persistent Store?

  • Can this code cause a memory leak (Arduino)

    - by tbraun89
    I have a arduino project and I created this struct: struct Project { boolean status; String name; struct Project* nextProject; }; In my application I parse some data and create Project objects. To have them in a list there is a pointer to the nextProject in each Project object expect the last. This is the code where I add new projects: void RssParser::addProject(boolean tempProjectStatus, String tempData) { if (!startProject) { startProject = true; firstProject.status = tempProjectStatus; firstProject.name = tempData; firstProject.nextProject = NULL; ptrToLastProject = &firstProject; } else { ptrToLastProject->nextProject = new Project(); ptrToLastProject->nextProject->status = tempProjectStatus; ptrToLastProject->nextProject->name = tempData; ptrToLastProject->nextProject->nextProject = NULL; ptrToLastProject = ptrToLastProject->nextProject; } } firstProject is an private instance variable and defined in the header file like this: Project firstProject; So if there actually no project was added, I use firstProject, to add a new one, if firstProject is set I use the nextProject pointer. Also I have a reset() method that deletes the pointer to the projects: void RssParser::reset() { delete ptrToLastProject; delete firstProject.nextProject; startProject = false; } After each parsing run I call reset() the problem is that the memory used is not released. If I comment out the addProject method there are no issues with my memory. Someone can tell me what could cause the memory leak?

  • Get active window title in X

    - by dutt
    I'm trying to get the title of the active window. The application is a background task so if the user has Eclipse open the function returns "Eclipse - blabla", so it's not getting the window title of my own window. I'm developing this in Python 2.6 using PyQt4. My current solution, borrowed and slightly modified from an old answer here at SO, looks like this: def get_active_window_title(): title = '' root_check = '' root = Popen(['xprop', '-root'], stdout=PIPE) if root.stdout != root_check: root_check = root.stdout for i in root.stdout: if '_NET_ACTIVE_WINDOW(WINDOW):' in i: id_ = i.split()[4] id_w = Popen(['xprop', '-id', id_], stdout=PIPE) for j in id_w.stdout: if 'WM_ICON_NAME(STRING)' in j: if title != j.split()[2]: return j.split("= ")[1].strip(' \n\"') It works for most windows, but not all. For example it can't find my kopete chat windows, or the name of the application i'm currently developing. My next try looks like this: def get_active_window_title(self): screen = wnck.screen_get_default() if screen == None: return "Could not get screen" window = screen.get_active_window() if window == None: return "Could not get window" title = window.get_name() return title; But for some reason window is always None. Does somebody have a better way of getting the current window title, or how to modify one of my ways, that works for all windows? Edit: In case anybody is wondering this is the way I found that seems to work for all windows. def get_active_window_title(self): root_check = '' root = Popen(['xprop', '-root'], stdout=PIPE) if root.stdout != root_check: root_check = root.stdout for i in root.stdout: if '_NET_ACTIVE_WINDOW(WINDOW):' in i: id_ = i.split()[4] id_w = Popen(['xprop', '-id', id_], stdout=PIPE) id_w.wait() buff = [] for j in id_w.stdout: buff.append(j) for line in buff: match = re.match("WM_NAME\((?P<type>.+)\) = (?P<name>.+)", line) if match != None: type = match.group("type") if type == "STRING" or type == "COMPOUND_TEXT": return match.group("name") return "Active window not found"

  • Need a refresher course on property access...

    - by Code Sherpa
    Hi. I need help with accessing class properties within a given class. For example, take the below class: public partial class Account { private Profile _profile; private Email _email; private HostInfo _hostInfo; public Profile Profile { get { return _profile; } set { _profile = value; } } public Email Email { get { return _email; } set { _email = value; } } public HostInfo HostInfo { get { return _hostInfo; } set { _hostInfo = value; } } In the class "Account" exists a bunch of class properties such as Email or Profile. Now, when I want to access those properties at run-time, I do something like this (for Email): _accountRepository = ObjectFactory.GetInstance<IAccountRepository>(); string username = Cryptography.Decrypt(_webContext.UserNameToVerify, "verify"); Account account = _accountRepository.GetAccountByUserName(username); if(account != null) { account.Email.IsConfirmed = true; But, I get "Object reference not set..." for account.Email... Why is that? How do I access Account such that account.Email, account.Profile, and so on returns the correct data for a given AccountId or UserName. Here is a method that returns Account: public Account GetAccountByUserName(string userName) { Account account = null; using (MyDataContext dc = _conn.GetContext()) { try { account = (from a in dc.Accounts where a.UserName == userName select a).FirstOrDefault(); } catch { //oops } } return account; } The above works but when I try: account = (from a in dc.Accounts join em in dc.Emails on a.AccountId equals em.AccountId join p in dc.Profiles on em.AccountId equals p.AccountId where a.UserName == userName select a).FirstOrDefault(); I am still getting object reference exceptions for my Email and Profile properties. Is this simply a SQL problem or is there something else I need to be doing to be able to fully access all the properties within my Account class? Thanks!

  • Null Pointer Exception in my BroadcastReceiver class

    - by user1760007
    I want to search a db and toast a specific column on the startup of the phone. The app keeps crashing and getting an exception even though I feel as the code is correct. @Override public void onReceive(Context ctx, Intent intent) { Log.d("omg", "1"); DBAdapter do = new DBAdapter(ctx); Log.d("omg", "2"); Cursor cursor = do.fetchAllItems(); Log.d("omg", "3"); if (cursor.moveToFirst()) { Log.d("omg", "4"); do { Log.d("omg", "5"); String title = cursor.getString(cursor.getColumnIndex("item")); Log.d("omg", "6"); // i = cursor.getInt(cursor.getColumnIndex("id")); Toast.makeText(ctx, title, Toast.LENGTH_LONG).show(); } while (cursor.moveToNext()); } cursor.close(); } The frustrating part is that I don't see any of my "omg" logs show up in logcat. I only see when my application crashes. I get three lines of errors in logcat. 10-19 12:31:11.656: E/AndroidRuntime(1471): java.lang.RuntimeException: Unable to start receiver com.test.toaster.MyReciever: java.lang.NullPointerException 10-19 12:31:11.656: E/AndroidRuntime(1471): at com.test.toaster.DBAdapter.fetchAllItems(DBAdapter.java:96) 10-19 12:31:11.656: E/AndroidRuntime(1471): at com.test.toaster.MyReciever.onReceive(MyReciever.java:26) For anyone interested, here is my DBAdapter fetchAllItems code: public Cursor fetchAllItems() { return mDb.query(DATABASE_TABLE, new String[] { KEY_ITEM, KEY_PRIORITY, KEY_ROWID }, null, null, null, null, null); }

  • Rails load path questions

    - by HelpMe
    Say I have some custom classes that don't belong in models, controllers etc, I should put this in /lib correct? In rails < 3 I would add this directory to my loadpath and in rails 3+ I would add this to my autoload_path. Is this correct? Now say I have some classes that extends already defined classes. Where should I put this so its run on startup. Forexample say I want to add the method 'foo' on String. class String def foo 'foo; end end Where should I put this class so it's defined on startup? Another weird bug I have is when I try to namespace classes in lib. module MyProject class Foo end end Now in a console: ruby-1.9.2-p136 :004 Bags::Foo LoadError: Expected /Users/me/workspace/my_project/lib/foo.rb to define Foo from /Users/rob/.rvm/gems/ruby-1.9.2-p136/gems/activesupport-3.0.3/lib/active_support/dependencies.rb:492:in `load_missing_constant' from /Users/rob/.rvm/gems/ruby-1.9.2-p136/gems/activesupport-3.0.3/lib/active_support/dependencies.rb:183:in `block in const_missing' I keep getting this error.

  • Android 2.1 How to get Phone Numbers of contacts.

    - by Brandon Delany
    Hi, I am new to Android and have been working on an app that needs to get all of the user's contact's phone numbers. Apparently the code I have does not work with the 2.1 SDK. So far here is the code I am using: String[] projection = new String[] { Phone.NUMBER }; Cursor c = managedQuery( Phone.CONTENT_URI, projection, null, null, null ); int colIndex = -1; try { colIndex = c.getColumnIndexOrThrow( Phone.NUMBER ); } catch( Exception e ) { print( e.getMessage() ); } print( "Column Index = " + colIndex ); //count is equal to 3 for( int i = 0; i < count; i++ ){ try { print( c.getString( 2 ) ); //the 2 used to be colIndex } catch ( Exception e ) { print( e.getMessage() ); } } It seems that no matter what I pass into c.getString() it keeps telling me that I passed in -1. But I even hardcoded the 2, and it says the same thing. Any help would be much appreciated.

  • ASP.NET: Page HTML head rendering

    - by Fabian
    I've been trying to figure out the best way to custom render the <head> element of a pag to get rid of the extra line breaks which is caused by <head runat="server">, so its properly formatted. So far the only thing i've found which works is the following: protected override void Render(HtmlTextWriter writer) { StringWriter stringWriter = new StringWriter(); HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter); base.Render(htmlTextWriter); htmlTextWriter.Close(); string html = stringWriter.ToString(); string newHTML = html.Replace("\r\n\r\n<!DOCTYPE", "<!DOCTYPE") .Replace("\r\n<html", "<html") .Replace("<title>\r\n\t", "<title>") .Replace("\r\n</title>", "</title>") .Replace("</head>", "\n</head>"); writer.Write(newHTML); } I define my had tag like Now i have 2 questions: How does the above code affect the performance (so is this viable in an production environment)? Is there a better way to do this, for example a method which i can override to just custom render the <head>? Oh yeah ASP.NET MVC is not an option.

    Hey everyone, Currently I have a file that I named JQuery.ext.js which I am including in all of my pages. Inside this file I have numerous functions that do things like the following, (function($) { /** * Checks to see is the value inside ele is blank * @param message string The message that needs to be displayed if the element is blank * @return bool */ $.fn.isEmpty = function(message) { var b_IsEmpty = false; //Loop through all elements this.each(function() { //Check to see if an empty value is found if($(this).val().length <= 0) { //If message is not blank if(message) { alert(message); $(this).focus().select(); } b_IsEmpty = true; return false; } return true; }); //Return false if the evaluation failed, otherwise return the jquery object so we can reuse it return (b_IsEmpty) ? true : false; }; /** * Checks to see if the value inside ele is numbers only * @param message string The message that needs to be displayed if the element is not numeric * @return bool */ $.fn.isNumeric = function(message) { var expression = /^[0-9]+$/; var b_IsNumeric = true; //Loop through elements checking each one this.each( function() { //Check to see if this value is not numeric if(!$(this).val().match(expression) && $(this).val().length > 0) { //If message is not blank if(message) { alert(message); $(this).focus().select(); } b_IsNumeric = false; } return b_IsNumeric; }); return b_IsNumeric; }; })(jQuery); Is there another way to do this? or is this the way most people do it? Thanks for any help, Metropolis

  • How to check at runtime if a class implements certain interface?

    - by mare
    Let's say I have some content classes like Page, TabGroup, Tab, etc. Certain of those will be implementing my IWidgetContainer interface - it means they will geet an additional field named ContainedItems from the interface and some methods for manipulating this field. Now I need to reflect the fact that some class implements this interface by rendering out some special custom controls in my ASP.NET MVC Views (like jQuery Add/Remove/Move/Reorder buttons). For instance, TabGroup will implement IWidgetContainer because it will contain tabs but a tab will not implement it because it won't have the ability to contain anything. So I have to somehow check in my view, when I render my content objects (The problem is, I use my base class as strong type in my view not concrete classes), whether it implements IWidgetContainer. How is that possible or have I completely missed something? To rephrase the question, how do you reflect some special properties of a class (like interface implementation) in the UI in general (not necessarily ASP.NET MVC)? Here's my code so far: [DataContract] public class ContentClass { [DataMember] public string Slug; [DataMember] public string Title; [DataMember] protected ContentType Type; } [DataContract] public class Group : ContentClass, IWidgetContainer { public Group() { Type = ContentType.TabGroup; } public ContentList ContainedItems { get; set; } public void AddContent(ContentListItem toAdd) { throw new NotImplementedException(); } public void RemoveContent(ContentListItem toRemove) { throw new NotImplementedException(); } } [DataContract] public class GroupElement : ContentClass { public GroupElement() { Type = ContentType.Tab; } } Interface: interface IWidgetContainer { [DataMember] ContentList ContainedItems { get; set; } void AddContent(ContentListItem toAdd); void RemoveContent(ContentListItem toRemove); }

  • Using linq2xml to query a single item deep within

    - by BrettRobi
    I'm wondering if there is a robust and graceful way using linq2xml to query an item deep within an xml hierarchy. For example: <?xml version="1.0" encoding="utf-8" ?> <data> <core id="01234"> <field1>some data</field1> <field2>more data</field2> <metadata> <response> <status code="0">Success</status> <content> <job>f1b5c3f8-e6b1-4ae4-905a-a7c5de3f13c6</job> <id>id of the content</id> </content> </response> </metadata> </core> </data> With this xml how do I query the value of without using something like this: var doc = XElement.Load("file.xml"); string id = (string)doc.Element("core") .Element("metadata") .Element("response") .Element("content") .Element("id"); I don't like the above approach because it is error prone (throws exception if any tag is missing in the hierarchy) and honestly ugly. Is there a more robust and graceful approach, perhaps using the sql-like syntax of linq?

  • C++ STL Map vs Vector speed

    - by sub
    In the interpreter for my experimental programming language I have a symbol table. Each symbol consists of a name and a value (the value can be e.g.: of type string, int, function, etc.). At first I represented the table with a vector and iterated through the symbols checking if the given symbol name fitted. Then I though using a map, in my case map<string,symbol>, would be better than iterating through the vector all the time but: It's a bit hard to explain this part but I'll try. If a variable is retrieved the first time in a program in my language, of course its position in the symbol table has to be found (using vector now). If I would iterate through the vector every time the line gets executed (think of a loop), it would be terribly slow (as it currently is, nearly as slow as microsoft's batch). So I could use a map to retrieve the variable: SymbolTable[ myVar.Name ] But think of the following: If the variable, still using vector, is found the first time, I can store its exact integer position in the vector with it. That means: The next time it is needed, my interpreter knows that it has been "cached" and doesn't search the symbol table for it but does something like SymbolTable.at( myVar.CachedPosition ). Now my (rather hard?) question: Should I use a vector for the symbol table together with caching the position of the variable in the vector? Should I rather use a map? Why? How fast is the [] operator? Should I use something completely different?

  • How does asp.net MVC remember my false values on postback?

    - by Michel
    Hi, This is working, but how??? I have a controller action for a post: [AcceptVerbs(HttpVerbs.Post )] public ActionResult Edit(Person person) { bool isvalid = ModelState.IsValid; etc. The Person object has a property BirthDate, type DateTime. When i enter some invalid data in the form, say 'blabla' which is obvious not a valid Datetime, it fills all the (other) Person properties with the correct data and the BirthDate property with a new blank DateTime. The bool isvalid has the value 'false'. So far so good. Then i do this: return View(p); and in the view i have this: <%= Html.TextBox("BirthDate", String.Format("{0:g}", Model.BirthDate)) %> <%= Html.ValidationMessage("BirthDate", "*") %> Ant there it comes: i EXPECTED the model to contain the new, blank DateTime because i didn't put any new data in. Second, when the View displays something, it must be a DateTime, because Model.BirthDate can't hold anything but a DateTime. But to my surprise, it shows a textbox with the 'blabla' value! (and the red * behind it) Which ofcourse is nice because the user can seee what he typed wrong, but how can that (blabla)string be transferred to the View in a DateTime field?

  • NUnit - Multiple properties of the same name? Linking to requirements

    - by Ryan Ternier
    I'm linking all our our System Tests to test cases and to our Requirements. Every requirement has an ID. Every Test Case / System Tests tests a variety of requirements. Every module of code links to multiple requirements. I'm trying to find the best way to link every system test to its driving requirements. I was hoping to do something like: [NUnit.Framework.Property("Release", "6.0.0")] [NUnit.Framework.Property("Requirement", "FR50082")] [NUnit.Framework.Property("Requirement", "FR50084")] [NUnit.Framework.Property("Requirement", "FR50085")] [TestCase(....)] public void TestSomething(string a, string b...) However, that will break because Property is a Key-Value pair. The system will not allow me to have multiple Properties with the same key. The reason I'm wanting this is to be able to test specific requirements in our system if a module changes that touches these requirements. Rather than run over 1,000 system tests on every build, this would allow us to target what to test based on changes done to our code. Some system tests run upwards of 5 minutes (Enterprise healthcare system), so "Just run all of them" isn't a viable solution. We do that, but only before promoting through our environments. Thoughts?
