  • Writing to a new log file each day with TraceSource

    - by Cipher
    I am using a logger in my application to write to files. The source, switch and listeners have been defined in the app.config file as follows: <system.diagnostics> <sources> <source name="LoggerApp" switchName="sourceSwitch" switchType="System.Diagnostics.SourceSwitch"> <listeners> <add name="myListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="myListener.log" /> </listeners> </source> </sources> <switches> <add name="sourceSwitch" value="Information" /> </switches> </system.diagnostics> Inside, my .cs code, I use the logger as follows: private static TraceSource logger = new TraceSource("LoggerApp"); logger.TraceEvent(TraceEventType.Information, 1, "{0} : Started the application", DateTime.Now); What would I have to do to create a new log file each day instead of writing to the same log file every time?

    i am trying to display a random string each time a button is pressed from a set of strings defined in strings.xml . this is an example of the strings ID's <string name="q0"> <string name="q1"> <string name="q2"> <string name="q3"> <string name="q4"> java code for getting a random string. private static final Random rgenerator = null; int RandomQ = R.string.q0 (rgenerator.nextInt(5) + 1); String q = getString(RandomQ); if i try to use this java code i get an error at "q0" in R.string.q0 which is The method q0(int) is undefined for the type R.string if i try to use the quick fix and create a method, it works. but it wont let me save or run the app because it replaces my create method and shows this message R.java was modified manually! Reverting to generated version! thanks for reading.

  • BlackBerry Deployment Strategies

    - by cagreen
    I'm new to large scale BB app deployment and I'm looking for some clarification on the various methods of deployment. Please bear with me as I'm sure there is more to it than my naive view would lead me to believe. My app is very targeted to corporate users and requires a subscription to some additional services before it can be used. In other words, it's not targeted towards the consumer market, so I'm not worried about people not being able to easily find it online. What do I need to be aware of when looking at deployment strategies? Any gotchas? From my understanding my choices are: - App World small upfront vendor fee users can easily search for and find my app billing handled by RIM 4 licensing models (static, single, pool, dynamic). Though I'm not sure I've seen enough info on the pool and dynamic to fully appreciate how it might help me. - Download from my website billing is handled by me can I enforce the number of licenses that are in use within an organization? is this easier/harder for a user? - What else am I missing?

  • .htacces Rewrite Rule to Keep .php File Extensions

    - by user2672112
    I'm upgrading my static website that had .php extensions on the content pages. I've created my own simple cms which will start retrieving data from mysql database from now on, keeping the url structure same as the old once. The cms has get function to retrieve url structure from the database. Overall it started working fine with .html when i tested. But when i change the .html extension to .php in my .htaccess code the content pages starts reflecting "Internal Server Error. The server encountered an internal error or misconfiguration and was unable to complete your request." Here is my .htaccess code which i've used: RewriteBase / Options +FollowSymLinks RewriteEngine On RewriteRule ^([^?]*).php$ content.php?pid=$1 Perhaps there is a conflict, here is the code with .html extension that actually works fine. RewriteBase / Options +FollowSymLinks RewriteEngine On RewriteRule ^([^?]*).html$ content.php?pid=$1 So basically, content pages with .html are working & .php are not working. But i need my content pages to be with .php Please help. Thanks in advance... :)

  • Approaches for animating a C# property over time?

    - by Mario Fritsch
    I'm currently trying to animate a bunch of public properties on certain objects. Usually they are of type float or vectors of floats (the type is known at compile-time). I want to be able to: assign a static value to them (MyObject.Duration = 10f;) or assign a random value to them by specifying a minimum and maximum value and optionally also a weight (MyObject.Duration = new RandomFloat(5f, 20f, 2f);) or "bind" this property to the property of another object (think of a child object binding some of its properties to its parent object, like its color or size or sth.) or assign sort of a keyframe animation to them, specifying a variable number of keyframes with timecode and the property's value at that specific point in time as well as information about how to interpolate between these frames The keyframes should be able to accept random values for each frame, both for the time and the property's value. What would be a practical approach for this kind of system? Currently I'm thinking about polymorphism: implement a base class or interface with a public Value-property and/or GetValue(float time)-method and then creating different sub classes like StaticValue, RandomValue, BindingValue and AnimatedValue implementing this base class or interface. Doesn't seem very elegant, though, and the initialization of even simple objects becomes a bit tedious. Another idea would be to implement these properties just as regular floats or vectors and create special "Modifier"-types binding to these properties. To retrieve the "real" value of the property, I'd first call any Modifier bound to the property, which would in turn update the actual object's property for me to retrieve later on. That would most likely mean using reflection at some point, which could be quite bad for performance as I'll probably have thousands of properties to update dozens of times per second. Any suggestions on this? Being a novice I'm (hopefully) missing some far more elegant and/or practical solution than I'm already playing around with :( Edit: Probably should have mentioned this earlier, but WPF isn't an option - it's not available on all targetted platforms, so I can't rely on it. I'm aware of its powerful databinding and animation capabilities, but I need to roll my own (or find some other lightweight alternative meeting my needs).

  • JAVA MySql multiple word search

    - by user1703849
    i have a database in MySql that has a name column in it which contains several words(description). I am connected to database with java through eclipse. I have a search, that returns results if only name field contains one word. id: name: info: type: 1 balloon big red balloon big 2 house expensive beautiful luxury 3 chicken wings deep fried wings tasty these are just random words but as an example my search can only see ex. balloon and then show info, but if i type chicken wings, it does nothing. so it possible somehow to search from columns with multiple words? this is my search code below import java.io.*; import java.sql.*; import java.util.*; class Search { public static void main(String[] args) { Scanner inp``ut = new Scanner(System.in); try { Connection con = DriverManager.getConnection( "jdbc:mysql://example/mydb", "user", "password"); Statement stmt = (Statement) con.createStatement(); System.out.print("enter search: "); String name = input.next(); String SQL = "SELECT * FROM menu where name LIKE '" + name + "'"; ResultSet rs = stmt.executeQuery(SQL); while (rs.next()) { System.out.println("Name: " +rs.getString("name")); System.out.println("Description: " + rs.getString("info") ); System.out.println("Price: " + rs.getString("Price")); } } catch (Exception e) { System.out.println("ERROR: " + e.getMessage()); } } }

  • Images from url to listview

    - by Andres
    I have a listview which I show video results from YouTube. Everything works fine but one thing I noticed is that the way it works seems to be a bit slow and it might be due to my code. Are there any suggestions on how I can make this better? Maybe loading the images directly from the url instead of using a webclient? I am adding the listview items in a loop from video feeds returned from a query using the YouTube API. The piece of code which I think is slowing it down is this: Feed<Video> videoFeed = request.Get<Video>(query); int i = 0; foreach (Video entry in videoFeed.Entries) { string[] info = printVideoEntry(entry).Split(','); WebClient wc = new WebClient(); wc.DownloadFile(@"http://img.youtube.com/vi/" + info[0].ToString() + "/hqdefault.jpg", info[0].ToString() + ".jpg"); string[] row1 = { "", info[0].ToString(), info[1].ToString() }; ListViewItem item = new ListViewItem(row1, i); YoutubeList.Items.Add(item); imageListSmall.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); imageListLarge.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); } public static string printVideoEntry(Video video) { return video.VideoId + "," + video.Title; } As you can see I use a Webclient which downloads the images so then I can use them as image in my listview. It works but what I'm concerned about is speed..any suggestions? maybe a different control all together?

  • PHP strtotime without leap-years

    - by Christian Sciberras
    With regards to this thread, I've developed a partial solution: function strtosecs($time,$now=null){ static $LEAPDIFF=86400; $time=strtotime($time,$now); return $time-((date('Y',$time)-1968)/4*$LEAPDIFF); } The function is supposed to get the number of seconds given a string without checking leap-years. It does this calculating the number of leap-years 1970 [(year-1986)/4], multiplying it by the difference in seconds between a leap-year and a normal year (which in the end, it's just the number of seconds in a day). Finally, I simply remove all those excess leap-year seconds from the calculated time. Here's some examples of the inputs/outputs: // test code echo strtosecs('+20 years',0).'=>'.(strtosecs('+20 years',0)/31536000); echo strtosecs('+1 years',0).'=>'.(strtosecs('+1 years',0)/31536000); // test output 630676800 => 19.998630136986 31471200 => 0.99794520547945 You will probably ask why am I doing a division on the output? It's to test it out; 31536000 is the number of seconds in a year, so that 19.99... should be 20 and 0.99... should be a 1. Sure, I could round it all and get "correct" answer, but I'm worried about the inaccuracies.

  • Android Camera intent creating two files

    - by Kyle Ramstad
    I am making a program that takes a picture and then shows it's thumbnail. When using the emulator all goes well and the discard button deletes the photo. But on a real device the camera intent saves the image at the imageUri variable and a second one that is named like if I had just opened up the camera and took a picture by itself. private static final int CAMERA_PIC_REQUEST = 1337; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.camera); //start camera values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, "New Picture"); values.put(MediaStore.Images.Media.DESCRIPTION,"From your Camera"); imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); image = (ImageView) findViewById(R.id.ImageView01); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); startActivityForResult(intent, CAMERA_PIC_REQUEST); //save the image buttons Button save = (Button) findViewById(R.id.Button01); Button close = (Button) findViewById(R.id.Button02); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) { try{ thumbnail = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri); image.setImageBitmap(thumbnail); } catch(Exception e){ e.printStackTrace(); } } else{ finish(); } } public void myClickHandler(View view) { switch (view.getId()) { case R.id.Button01: finish(); break; case R.id.Button02: dicard(); } } private void dicard(){ getContentResolver().delete(imageUri, null, null); finish(); }

  • How do I create an exception-wrapping fubumvc behaviour?

    - by Jon M
    How can I create a fubumvc behaviour that wraps actions with a particular return type, and if an exception occurs while executing the action, then the behaviour logs the exception and populates some fields on the return object? I have tried the following: public class JsonExceptionHandlingBehaviour : IActionBehavior { private static readonly Logger logger = LogManager.GetCurrentClassLogger(); private readonly IActionBehavior _innerBehavior; private readonly IFubuRequest _request; public JsonExceptionHandlingBehaviour(IActionBehavior innerBehavior, IFubuRequest request) { _innerBehavior = innerBehavior; _request = request; } public void Invoke() { try { _innerBehavior.Invoke(); var response = _request.Get<AjaxResponse>(); response.Success = true; } catch(Exception ex) { logger.ErrorException("Error processing JSON request", ex); var response = _request.Get<AjaxResponse>(); response.Success = false; response.Exception = ex.ToString(); } } public void InvokePartial() { _innerBehavior.InvokePartial(); } } But, although I get the AjaxResponse object from the request, any changes I make don't get sent back to the client. Also, any exceptions thrown by the action don't make it as far as this, the request is terminated before execution gets to the catch block. What am I doing wrong? For completeness, the behaviour is wired up with the following in my WebRegistry: Policies .EnrichCallsWith<JsonExceptionHandlingBehaviour>(action => typeof(AjaxResponse).IsAssignableFrom(action.Method.ReturnType)); And AjaxResponse looks like: public class AjaxResponse { public bool Success { get; set; } public object Data { get; set; } public string Exception { get; set; } }

  • Do not get the rootLayoutContainer in a Fragment (Android 3.0 Preview)

    - by Hawk66
    Hello, I'm currently getting into the fragment API of the Android 3.0 Preview and have built the following minimal coding: I have an Activty, which shall embed Fragment(s), which is currently implemented like this: public class Cockpit extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.cockpit); } public static class InfoFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment ViewGroup infoFragmentRoot = (ViewGroup) getActivity().findViewById( R.id.infoFragmentRoot) ; return inflater.inflate(R.id.infoFragment, container, false); } } } The corresponding layout of the activity: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <fragment android:name="test.android.ui.cockpit.Cockpit$InfoFragment" android:id="@+id/infoFragment" android:layout_weight="1" android:layout_width="10dp" android:layout_height="match_parent" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="12dp" android:id="@+id/infoFragmentRoot" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> </fragment> Now, I do not understand why the ViewGroup container in the onCreateView() in the internal class InfoFragment is a nullpointer, nor do I understand, why ViewGroup infoFragmentRoot = (ViewGroup) getActivity().findViewById( R.id.infoFragmentRoot) ; returns also null. Thanks for feedback.

  • In which year was the date the same as the original year?

    - by Marta
    It's my first question on this site, but I always found this site really useful. What I mean with my question is: you ask the person to give a date (eg. Fill in a date [dd-mm-yyyy]: 16-10-2013) you than have to ask an interval between 2 years (eg. Give an interval [yyyy-yyyy]:1800-2000) When the program runs, it has to show what day of the week the given date is. In this case it was a Wednesday. Than the program has to look in which year, in between the interval, the date 16 October also fell on a Wednesday. So in the end it has to look something like this: Fill in a date: [dd-mm-yyyy]: 16-10-2013 Give an interval [yyyy-yyyy]: 1900-2000 16 October was a wednesday in the following years: 1905 1911 1916 1922 1933 1939 1944 1950 1961 1967 1972 1978 1989 1995 2000 The full date is Wednesday 16 October, 2013 The small (or biggest) problem is, I am not allowed to use the DATE.function in java. If someone can help me with the second part I would be really really happy, cause I have no idea how I am supposed to do this To find out what day of the week the given date falls, I use the Zeller Congruence class Day { Date date; //To grab the month and year form the Date class int day; final static String[] DAYS_OF_WEEK = { "Saturday", "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday" }; public void dayWeekInterval{ //code to grab the interval from interval Class, and doing stuff here } public void dayOfTheWeek { int m = date.getMonth(); int y = date.getYear(); if (m < 3) { m += 12; y -= 1; } int k = y % 100; int j = y / 100; int day = ((q + (((m + 1) * 26) / 10) + k + (k / 4) + (j / 4)) + (5 * j)) % 7; return day; } public string ToString(){ return "" + DAYS_OF_WEEK[day] + day; } }

  • Android - Where to store generated bitmaps?

    - by Josh
    I've got an app which dynamically generates anywhere from 6 to 100 small bitmaps for the user to move around the screen in a given session. I currently generate them in onCreate and store them to the sd card, so that after an orientation change I can grab them out of external storage and display them again. However, this takes time (the loading) and I'd like to keep the bitmap references around between lifecyle changes for quicker access. My question is, is there a better place to store my generated bitmaps? I was thinking about creating a static storage library in my base activity, something that would only need to be reloaded when the app is completely removed from memory (shutdown, other apps need resources, 30 minute restart, etc). Ideally, I'd like the user to be able to back out to the title screen, click a "Resume" button, and in onCreate I just have access to those resident bitmap references instead of having to load them from storage again. For this reason I don't think Activity.onRetainNonConfigurationInstance is what I need. Alternatively, is there a better way to handle multiple generated bitmaps than what I'm doing or the plan I described?

  • Does everything after my try statement have to be encompassed in that try statement to access variab

    - by Mithrax
    I'm learning java and one thing I've found that I don't like, is generally when I have code like this: import java.util.*; import java.io.*; public class GraphProblem { public static void main(String[] args) { if (args.length < 2) { System.out.println("Error: Please specify a graph file!"); return; } FileReader in = new FileReader(args[1]); Scanner input = new Scanner(in); int size = input.nextInt(); WeightedGraph graph = new WeightedGraph(size); for(int i = 0; i < size; i++) { graph.setLabel(i,Character.toString((char)('A' + i))); } for(int i = 0; i < size; i++) { for(int j = 0; j < size; j++) { graph.addEdge(i, j, input.nextInt()); } } // .. lots more code } } I have an uncaught exception around my FileReader. So, I have to wrap it in a try-catch to catch that specific exception. My question is does that try { } have to encompass everything after that in my method that wants to use either my FileReader (in) or my Scanner (input)? If I don't wrap the whole remainder of the program in that try statement, then anything outside of it can't access the in/input because it may of not been initialized or has been initialized outside of its scope. So I can't isolate the try-catch to just say the portion that intializes the FileReader and close the try statement immediately after that. So, is it the "best practice" to have the try statement wrapping all portions of the code that are going to access variables initialized in it? Thanks!

I can change the state of the thread that is not a problem Thanks again

  • WPF Binding to variable / DependencyProperty

    I'm playing around with WPF Binding and variables. Apparently one can only bind DependencyProperties. I have come up with the following, which works perfectly fine: The code-behind file: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } public string Test { get { return (string)this.GetValue(TestProperty); } set { this.SetValue(TestProperty, value); } //set { this.SetValue(TestProperty, "BBB"); } } public static readonly DependencyProperty TestProperty = DependencyProperty.Register( "Test", typeof(string), typeof(MainWindow), new PropertyMetadata("CCC")); private void button1_Click(object sender, RoutedEventArgs e) { MessageBox.Show(Test); Test = "AAA"; MessageBox.Show(Test); } } XAML: <Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" Title="MainWindow" Height="350" Width="525" DataContext="{Binding RelativeSource={RelativeSource Self}}"> <Grid> <TextBox Height="31" HorizontalAlignment="Left" Margin="84,86,0,0" Name="textBox1" VerticalAlignment="Top" Width="152" Text="{Binding Test, Mode=TwoWay, diag:PresentationTraceSources.TraceLevel=High}"/> <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="320,85,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> <TextBox Height="31" HorizontalAlignment="Left" Margin="84,138,0,0" Name="textBox2" Text="{Binding Test, Mode=TwoWay}" VerticalAlignment="Top" Width="152" /> </Grid> The two TextBoxes update one an other. And the Button sets them to "AAA". But now I replaced the Setter function with the one that is commented out (simulating some manipulation of the given value). I would expect that whenever the property value is changed it will be reset to "BBB". It does so when you press the button, that is when you set the property in code. But it does for some reason not affect the WPF Bindings, that is you can change the TextBox contents and thus the property, but apparently the Setter is never called. I wonder why that is so, and how one would go about to achive the expected behaviour.

  • How to use a rewrite rule to force calls for "domain.tld/subdir/file.html" to show as "subdir.domain.tld/file.html"?

    - by Wion
    Hi! First time poster. Very new to mod_rewrite. I'm on a shared server and the context of this problem is with a virtual directory under my root account. The domain (domain.tld) will have subdirectories representing annual mini-sites of static .html files. Subdirectory names (yyyy) will be the 4-digit year (e.g., "2010"). I want any call to domain.tld/yyyy/file.html to appear as yyyy.domain.tld/file.html in the browser address bar, and (of course) for the page to load properly. I already force dropping “www” by using… RewriteCond %{HTTP_HOST} ^www\.domain\.tld [NC] RewriteRule (.*) http://domain.tld/$1 [R=301,L] So far so good. But no matter what I try after that, I can’t get the subdomain to force to the front of the domain. Here’s one of the more complicated examples I’ve tried (no doubt wrong)… RewriteCond %{HTTP_HOST} ^domain\.tld/([0-9]+)/([a-z-]+)\.html [NC] RewriteRule (.*) %1.domain.tld/%2.html [NC] This doesn’t break anything (that I can tell), but it doesn’t do what I want either. I.e., if I type yyyy.domain.tld, I’ll see yyyy.domain.tld in the address bar, and navigating around will give me yyyy.domain.tld/file.html, etc. Fine. But if also type domain.tld/yyyy I’ll see domain.tld/yyyy, etc, which is not how I want people to see it. It doesn’t redirect or mask or alias or whatever you call it. Is it even possible to force one look over the other like that? Should I be handling this with DNS instead? Thanks in advance!

  • Generating authentication header from azure table through objective-c

    - by user923370
    I'm fetching data from iCloud and for that I need to generate a header (azure table storage). I used the code below for that and it is generating the headers. But when I use these headers in my project it is showing "make sure that the value of authorization header is formed correctly including the signature." I googled a lot and tried many codes but in vain. Can anyone kindly please help me with where I'm going wrong in this code. -(id)generat{ NSString *messageToSign = [NSString stringWithFormat:@"%@/%@/%@", dateString,AZURE_ACCOUNT_NAME, tableName]; NSString *key = @"asasasasasasasasasasasasasasasasasasasasas=="; const char *cKey = [key cStringUsingEncoding:NSUTF8StringEncoding]; const char *cData = [messageToSign cStringUsingEncoding:NSUTF8StringEncoding]; unsigned char cHMAC[CC_SHA256_DIGEST_LENGTH]; CCHmac(kCCHmacAlgSHA256, cKey, strlen(cKey), cData, strlen(cData), cHMAC); NSData *HMAC = [[NSData alloc] initWithBytes:cHMAC length:sizeof(cHMAC)]; NSString *hash = [Base64 encode:HMAC]; NSLog(@"Encoded hash: %@", hash); NSURL *url=[NSURL URLWithString: @"http://my url"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request addValue:[NSString stringWithFormat:@"SharedKeyLite %@:%@",AZURE_ACCOUNT_NAME, hash] forHTTPHeaderField:@"Authorization"]; [request addValue:dateString forHTTPHeaderField:@"x-ms-date"]; [request addValue:@"application/atom+xml, application/xml"forHTTPHeaderField:@"Accept"]; [request addValue:@"UTF-8" forHTTPHeaderField:@"Accept-Charset"]; NSLog(@"Headers: %@", [request allHTTPHeaderFields]); NSLog(@"URL: %@", [[request URL] absoluteString]); return request; } -(NSString*)rfc1123String:(NSDate *)date { static NSDateFormatter *df = nil; if(df == nil) { df = [[NSDateFormatter alloc] init]; df.locale = [[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"] autorelease]; df.timeZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"]; df.dateFormat = @"EEE',' dd MMM yyyy HH':'mm':'ss 'GMT'"; } return [df stringFromDate:date]; }

  • Manually wiring up unobtrusive jquery validation client-side without Model/Data Annotations, MVC3

    - by cmorganmcp
    After searching and experimenting for 2 days I relent. What I'd like to do is manually wire up injected html with jquery validation. I'm getting a simple string array back from the server and creating a select with the strings as options. The static fields on the form are validating fine. I've been trying the following: var dates = $("<select id='ShiftDate' data-val='true' data-val-required='Please select a date'>"); dates.append("<option value=''>-Select a Date-</option>"); for (var i = 0; i < data.length; i++) { dates.append("<option value='" + data[i] + "'>" + data[i] + "</option>"); } $("fieldset", addShift).append($("<p>").append("<label for='ShiftDate'>Shift Date</label>\r").append(dates).append("<span class='field-validation-valid' data-valmsg-for='ShiftDate' data-valmsg-replace='true'></span>")); // I tried the code below as well instead of adding the data-val attributes and span manually with no luck dates.rules("add", { required: true, messages: { required: "Please select a date" } }); // Thought this would do it when I came across several posts but it didn't $.validator.unobtrusive.parse(dates.closest("form")); I know I could create a view model ,decorate it with a required attribute, create a SelectList server-side and send that, but it's more of a "how would I do this" situation now. Can anyone shed light on why the above code wouldn't work as I expect? -chad
