  • beforeClose not working in jGrowl?

    - by sparkymark75
    I have the following code which pulls json data from an ASP.NET page and displays these as notifications. The code will also take a note of what's been pulled through and store it in an array to prevent it being shown again in the same session. I'm now trying to implement functionality so that when the user closes a message, it's ID is recorded in a cookie to prevent it ever being shown again. To do this, I'm trying to write to the cookie when the beforeClose event fires. Everything else works fine apart from the saving to a cookie bit. Is there something wrong with my code that I'm missing? var alreadyGrowled = new Array(); var noteCookie = $.cookie("notificationsViewed"); if (noteCookie != null) { alreadyGrowled = noteCookie.split(","); } function growlCheckNew() { $.getJSON('getNotifications.aspx', function(data) { $(data).each(function(entryIndex, entry) { var newMessage = true; $(alreadyGrowled).each(function(index, msg_id) { if (entry['ID'] == msg_id) { newMessage = false; } }); if (newMessage == true) { $.jGrowl(entry['Message'], { sticky: true, header: entry['Title'], beforeClose: function(e, m) { $.cookie("notificationsViewed", entry['ID']); } }); } alreadyGrowled.push(entry['ID']); }); }); }

  • Problem with displaying image from DB using asp.net MVC 2

    - by Renato
    Hello! I'm having trouble with displaying image from db. I think that method for saving image is working, because I see in DB that varbinary fields have some value, and that image type is correct. Also the size of image. But when I want to display image for product i don't get anything. Just blank space.. here is my code... public byte[] GetImage(int productID) { Product product = products.GetByID(productID); byte[] imageData = product.ImageData.ToArray(); return imageData; } That code is in my controller. Second is code from view : <% if (product.ImageData != null) { %> <img src='/product/getimage/<%= Html.Encode(product.ID) %>' alt=""/> <% } %> I tried some solutions found here on stack overflow, and everyone do it like this, but it's working for them. I dont have any idea why images aren't displayed. When i look at source code of page at debugging i have : <img src='/product/getimage/18' alt=""/> I'm using .net 4.0, MVC 2, VS 2010... Thanks in advance

  • HTTP Handler error when downloading files - SSL

    - by Chiefy
    Ok big problem as this is affecting two projects on our new server. We have a file that is downloaded by users, the files are downloaded using a HTTPHandler. Since moving the site to the server and setting SSL the downloads have stopped working and we get an error message "Unable to download DownloadDocument.ashx" from site". DownloadDocument.ashx is the handler page that is set in the web.config and the button that goes there is a hyperlink with the id of the document as a querystring. Ive read the article on http://support.microsoft.com/kb/316431 and read a few other requests on this site but nothing seems to be working. This problem only happens in IE and works fine when I run it on the server in http instead of https. public override void HandleRequest(HttpContext context) { Guid guid = new Guid(context.Request.QueryString["ID"]); DataTable dt = Documents.GetDocument(guid); if (dt != null) { context.Response.Cache.SetCacheability(HttpCacheability.Private); context.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", dt.Rows[0]["DocumentName"].ToString())); context.Response.AddHeader("Content-Transfer-Encoding", "binary"); context.Response.AddHeader("Content-Length", ((byte[])dt.Rows[0]["Document"]).Length.ToString()); context.Response.ContentType = string.Format("application/{0}", dt.Rows[0]["Extension"].ToString().Remove(0, 1)); context.Response.Buffer = true; context.Response.BinaryWrite((byte[])dt.Rows[0]["Document"]); context.Response.Flush(); context.Response.End(); } } The above is my current code for the request. Ive used the base handler on http://haacked.com/archive/2005/03/17/AnAbstractBoilerplateHttpHandler.aspx. Any ideas on what this might be and how we can fix it. Thanks in advance for all responses.

  • Can't access resource from Generic.xaml within the Custom Control constructor.

  • JPA concatenating table names for parent/child @OneToMany

    - by Robert
    We are trying to use a basic @OneToMany relationship: @Entity @Table(name = "PARENT_MESSAGE") public class ParentMessage { @Id @Column(name = "PARENT_ID") @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer parentId; @OneToMany(fetch=FetchType.LAZY) private List childMessages; public List getChildMessages() { return this.childMessages; } ... } @Entity @Table(name = "CHILD_MSG_USER_MAP") public class ChildMessage { @Id @Column(name = "CHILD_ID") @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer childId; @ManyToOne(optional=false,targetEntity=ParentMessage.class,cascade={CascadeType.REFRESH}, fetch=FetchType.LAZY) private ParentMessage parentMsg; public ParentMessage getParentMsg() { return parentMsg; } ... } ChildMessage child = new ChildMessage(); em.getTransaction().begin(); ParentMessage parentMessage = (ParentMessage) em.find(ParentMessage.class, parentId); child.setParentMsg(parentMessage); List list = parentMessage.getChildMessages(); if(list == null) list = new ArrayList(); list.add(child); em.getTransaction().commit(); We receive the following error. Why is OpenJPA concatenating the table names to APP.PARENT_MESSAGE_CHILD_MSG_USER_MAP?

  • How to close all tabs in Safari using AppleScript?

    - by Form
    I have made a very simple AppleScript to close all tabs in Safari. The problem is, it works, but not completely. Here's the code: tell application "Safari" repeat with aWindow in windows repeat with aTab in tabs of aWindow aTab close end repeat end repeat end tell I've also tried this script: tell application "Safari" repeat with i from 0 to the number of items in windows set aWindow to item i of windows repeat with j from 0 to the number of tabs in aWindow set aTab to item j of tabs of aWindow aTab close end repeat end repeat end tell ... but it does not work either. I tried that on my system (MacBook Pro jan 2008), as well as on a Mac Pro G5 under Tiger and the script fails on both, albeit with a much less descriptive error on Tiger. The problem is that only a couple of tabs are closed. Running the script a few times closes a few tab each time until none is left, but always fails with the same error after closing a few tabs. Under Leopard I get an out of bounds error. Since I am using fast enumeration (not using "repeat from 0 to number of items in windows") I don't see how I can get an out of bounds error with this... My goal is to use the Cocoa Scripting Bridge to close tabs in Safari from my Objective-C Cocoa application but the Scripting Bridge fails in the same manner. The non-deletable tabs show as NULL in the Xcode debugger, while the other tabs are valid objects from which I can get values back (such as their title). In fact I tried with the Scripting Bridge first then told myself why not try this directly in AppleScript and I was surprised to see the same results. I must have a glaring omission or something in there... (seems like a bug in Safari AppleScript support to me... :S) I've used repeat loops and Obj-C 2.0 fast enumeration to iterate through collections before with zero problems, so I really don't see what's wrong here. Anyone can help? Thanks in advance!

  • How to refresh/redraw the screen (not the program window)

    - by mohrphium
    I'm having a bit of a hard time figuring out, how to remove a drawn ellipse after it has been drawn somewhere else. I need a circle to follow my mouse all the time and this is all the program should do. I get the mousepositions and draw my circle but how can I remove the last one? #include <Windows.h> #include <iostream> void drawRect(int a1, int a2){ HDC screenDC = ::GetDC(0); //Draw circle at mouse position ::Ellipse(screenDC, a1, a2+5, a1+9, a2+14); ::ReleaseDC(0, screenDC); //::InvalidateRect(0, NULL, TRUE); //<- I tried that but then everything flickers //Also, the refresh rate is not fast enough... still some circles left } int main(void) { int a1; int a2; bool exit=false; while (exit!=true) { POINT cursorPos; GetCursorPos(&cursorPos); float x = 0; x = cursorPos.x; float y = 0; y = cursorPos.y; a1=(int)cursorPos.x; a2=(int)cursorPos.y; drawRect(a1, a2); } } I am working with graphics and all that stuff for the first time. Im kinda stuck here... once again. Thanks.

  • WPF data-bound ComboBox only shows first item of ItemsSource list

    - by Mark
    Hi all, I'm sure I'm doing something stupid but for the life of me I can't think of right now. I have a ComboBox that is data-bound to a list of Layout objects. The list is initially empty but things are added over time. When the list is updated by the model the first time, this update reflects properly in the ComboBox. However, subsequent updates never show up in the ComboBox even though I can see that the list itself contains these items. Since the first update works, I know the data-binding is OK - so what am I doing wrong here? Here's the XAML (abridged): <Grid HorizontalAlignment="Stretch"> <ComboBox ItemsSource="{Binding Path=SavedLayouts, diagnostics:PresentationTraceSources.TraceLevel=High}" DisplayMemberPath="Name" SelectedValuePath="Name" SelectedItem="{Binding LoadLayout}" Height="25" Grid.Row="1" Grid.Column="0"></ComboBox> </Grid> And the related part of the model: public IList<Layout> SavedLayouts { get { return _layouts; } } public Layout SaveLayout( String data_ ) { Layout theLayout = new Layout( SaveLayoutName ); _layouts.Add( theLayout ); try { return theLayout; } finally { PropertyChangedEventHandler handler = PropertyChanged; if( handler != null ) { handler( this, new PropertyChangedEventArgs( "SavedLayouts" ) ); } } } And finally, the layout class (abridged): public class Layout { public String Name { get; private set; } } In the output window, I can see the update occurring: System.Windows.Data Warning: 91 : BindingExpression (hash=64564967): Got PropertyChanged event from TickerzModel (hash=43624632) System.Windows.Data Warning: 97 : BindingExpression (hash=64564967): GetValue at level 0 from TickerzModel (hash=43624632) using RuntimePropertyInfo(SavedLayouts): List`1 (hash=16951421 Count=11) System.Windows.Data Warning: 76 : BindingExpression (hash=64564967): TransferValue - got raw value List`1 (hash=16951421 Count=11) System.Windows.Data Warning: 85 : BindingExpression (hash=64564967): TransferValue - using final value List`1 (hash=16951421 Count=11) But I get do not get this 11th item in the ComboBox. Any ideas?

  • Multiple generic parameters on a html helper extension method

    - by WestDiscGolf
    What I'm trying to do is create an extension method for the HtmlHelper to create a specific output and associated details like TextBoxFor<. What I want to do is specify the property from the model class as per TextBoxFor<, then an associated controller action and other parameters. So far the signature of the method looks like: public static MvcHtmlString Create<TModel, TProperty, TController>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, Expression<Action<TController>> action, object htmlAttributes) where TController : Controller where TModel : class The issue occurs when I go to call it. In my view if I call it as per the TextBoxFor without specifying the Model type I am able to specify the lambda expression to set the property which it's for, but when I go to specify the action I am unable to. However, when I specify the controller type Html.Create<HomeController>( ... ) I am unable to specify the model property that the control is to be created for. I want to be able to call it like <%= Html.Create(x => x.Title, controller => controller.action, null) %> I've been hitting my head for a few hours now on this issue over the past day, can anyone point me in the right direction?

  • IE "Microsoft JScript runtime error: Object expected"

    - by Stephen Borg
    Hi there, I have problems with regards to javascript only when using IE. The error I am getting is "Microsoft JScript runtime error: Object expected" and I have no idea why. It is then jumping into the JQuery 1.4.2 file, without giving me a proper error message. All I am doing is simply reading on page load the raw URL, and getting a query string named Search. Using that in an AJAX call to return products and put then into a DIV. No biggies, but somehow IE is managing to blow my page up :-( Any ideas? Code as follows : <script type="text/javascript"> $(document).ready(function (e) { $('.boxLoader').show(); function getParameterByName(name) { name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regexS = "[\\?&]" + name + "=([^&#]*)"; var regex = new RegExp(regexS); var results = regex.exec(window.location.href); if (results == null) return ""; else return decodeURIComponent(results[1].replace(/\+/g, " ")); } var Search; Search = getParameterByName("search"); $('#searchCriteria').text(Search); $.get("/Handlers/processProducts.aspx", { SearchCriteria: Search }, function (data) { $('#innercontent').html(data); $('#innercontent').fadeIn(200); $('.boxLoader').fadeOut(200); }); $('#searchBox').live("click", function () { $.get("/Handlers/processProducts.aspx", { SearchCriteria: $('#searchCriteria').val() }, function (data) { $('#innercontent').html(data); $('#innercontent').fadeIn(200); $('.boxLoader').fadeOut(200); }); }); }); </script>

  • Sharepoint user details not visible to other users

    - by richardoz
    I am managing a SharePoint site that uses Form Based Authentication. We have several generic lists, document libraries and active task lists that users can create update and delete. Users can use the people pickers to select/search for everyone. But the users cannot see other users names, email addresses etc. in display lists or the people pickers. If I log in as the site collection administrator, I can see everyones details. So I know the data is available. Updated details on this problem (non-administrators) SharePoint users cannot see other users information. Example: User A assigns a task to user B. User A creates a new task and uses the people picker to find user B. User B is only visible by the login name “bname” and any information about user B is not visible or searchable within the people picker. Once user B is assigned the task, user A no longer sees the name in the task list – even though user A created it. No modified by, created by, assigned to or owner field data is visible to non-administrator users. Facts: Extranet site is configured to use Forms Based Authentication. Intranet uses windows based authentication Users of both the intranet and extranet have the same problem All databases are local The site uses SSRS integration SharePoint WSS on Windows 2003 Std -- After activating the verbose logging it looks like SharePoint is definately asking SQL server for only the user info for the currently logged in user: SELECT TOP 6 /lots-of-columns/ FROM UserData INNER MERGE JOIN Docs AS t1 ON ( 1 = 1 AND UserData.[tp_RowOrdinal] = 0 AND t1.SiteId = UserData.tp_SiteId AND t1.SiteId = @L2 AND t1.DirName = UserData.tp_DirName AND t1.LeafName = UserData.tp_LeafName AND t1.Level = UserData.tp_Level AND t1.IsCurrentVersion = 1 AND (1 = 1) ) LEFT OUTER JOIN AllUserData AS t2 ON ( UserData.[tp_Author]=t2.[tp_ID] AND UserData.[tp_RowOrdinal] = 0 AND t2.[tp_RowOrdinal] = 0 AND ( (t2.tp_IsCurrent = 1) ) AND t2.[tp_CalculatedVersion] = 0 AND t2.[tp_DeleteTransactionId] = 0x AND t2.tp_ListId = @L3 AND UserData.tp_ListId = @L4 AND t2.[tp_Author]=162 /* this is the currently logged in user */ ) WHERE (UserData.tp_IsCurrent = 1) AND UserData.tp_SiteId=@L2 AND (UserData.tp_DirName=@DN) AND UserData.tp_RowOrdinal=0 AND ( ( (UserData.[datetime1] IS NULL ) OR (UserData.[datetime1] = @L5DTP) ) AND t1.SiteId=@L2 AND (t1.DirName=@DN) ) ORDER BY UserData.[tp_Modified] Desc, UserData.[tp_ID] Asc Again, any ideas would be appreciated.

  • How to join results from two different sets in LINQ?

    - by Inez
    Hi, I get some data about customers in my database with this method: public List<KlientViewModel> GetListOfKlientViewModel() { List<KlientViewModel> list = _klientRepository.List().Select(k => new KlientViewModel { Id = k.Id, Imie = k.Imie, Nazwisko = k.Nazwisko, Nazwa = k.Nazwa, SposobPlatnosci = k.SposobPlatnosci, }).ToList(); return list; } but also I have another method which counts value for extra field in KlientViewModel - field called 'Naleznosci'. I have another method which counts value for this field based on customers ids, it looks like this: public Dictionary<int, decimal> GetNaleznosc(List<int> klientIds) { return klientIds.ToDictionary(klientId => klientId, klientId => (from z in _zdarzenieRepository.List() from c in z.Klient.Cennik where z.TypZdarzenia == (int) TypyZdarzen.Sprzedaz && z.IdTowar == c.IdTowar && z.Sprzedaz.Data >= c.Od && (z.Sprzedaz.Data < c.Do || c.Do == null) && z.Klient.Id == klientId select z.Ilosc*(z.Kwota > 0 ? z.Kwota : c.Cena)).Sum() ?? 0); } So what I want to do is to join data from method GetNaleznosc with data generated in method GetListOfKlientViewModel. I call GetNaleznosc like this: GetNaleznosc(list.Select(k => k.Id).ToList()) but don't know what to do next.

  • What is wrong with locking non-static fields? What is the correct way to lock a particular instance?

    - by smartcaveman
    Why is it considered bad practice to lock non-static fields? And, if I am not locking non-static fields, then how do I lock an instance method without locking the method on all other instances of the same or derived class? I wrote an example to make my question more clear. public abstract class BaseClass { private readonly object NonStaticLockObject = new object(); private static readonly object StaticLockObject = new object(); protected void DoThreadSafeAction<T>(Action<T> action) where T: BaseClass { var derived = this as T; if(derived == null) { throw new Exception(); } lock(NonStaticLockObject) { action(derived); } } } public class DerivedClass :BaseClass { private readonly Queue<object> _queue; public void Enqueue(object obj) { DoThreadSafeAction<DerivedClass>(x=>x._queue.Enqueue(obj)); } } If I make the lock on the StaticLockObject, then the DoThreadSafeAction method will be locked for all instances of all classes that derive from BaseClass and that is not what I want. I want to make sure that no other threads can call a method on a particular instance of an object while it is locked.

If on another screen Categories are updated (or from another user in the network), we would like to be able to reload the Categories, while preserving the context we currently use, since we could be in the middle of editing data, and we do not want changes to be lost (and we cannot depend on saving, since we have incomplete data). Since there is no easy way to tell EF to get fresh data (added, removed and modified), we thought of twp possible ways: 1) Getting products attached to context, and categories detached from context. This would mean that we loose the ability to access Product.Category.Name, which we do sometimes require, so we would need to manually resolve it (example when printing data). 2) detaching / attaching all Categories from current context. Context.ChangeTracker.Entries().Where(x => x.Entity.GetType() == typeof(T)).ForEach(x => x.State = EntityState.Detached); And then reload the categories, which will get fresh data. Do you find any problem with this second approach? We understand that this will require all constraints to be put on foreign keys, and not navigation properties, since when detaching all Categories, Product.Category navigation properties would be reset to null also. Also, there could be a potential performance problem, which we did not test, since there could be couple of thousand products loaded, and all would need to resolve navigation property when reloading. Which of the two do you prefer, and is there a better way (EF6 + .NET 4.0)?

  • Components don't show in custom JPanel/JComponent

    - by Bart van Heukelom
    I've created a custom swing component. I can see it (the grid from the paint method is drawn), but the buttons that are added (verified by println) aren't shown. What am I doing wrong? Background information: I'm trying to build a tree of visible objects like the Flash/AS3 display list. public class MapPanel extends JComponent { // or extends JPanel, same effect private static final long serialVersionUID = 4844990579260312742L; public MapPanel(ShapeMap map) { setBackground(Color.LIGHT_GRAY); setPreferredSize(new Dimension(1000,1000)); setLayout(null); for (Layer l : map.getLayers()) { // LayerView layerView = new LayerView(l); // add(layerView); System.out.println(l); JButton test = new JButton(l.getName()); add(test); validate(); } } @Override protected void paintComponent(Graphics g) { // necessary? super.paintComponent(g); // background g.setColor(getBackground()); g.fillRect(0, 0, getWidth(), getHeight()); // grid g.setColor(Color.GRAY); for (double x = 0; x < getWidth(); x += 10) { g.drawLine((int)x, 0, (int)x, getHeight()); } for (double y = 0; y < getHeight(); y += 10) { g.drawLine(0, (int)y, getWidth(), (int)y); } } }

  • Drupal administration theme doesn't apply to Blocks pages (admin/build/block)

    - by hfidgen
    A site I'm creating for a customer in D6 has various images overlaying parts of the main content area. It looks very pretty and they have to be there for the general effect. The problem is, if you use this theme in the administration pages, the images get in the way of everything. My solution was to create a custom admin theme, based on the default one, which has these image areas disabled in the output template files - page.tpl.php The problem is that when you try and edit the blocks page, it uses the default theme and half the blocks admin settings are unclickable behind the images. I KNOW this is by design in Drupal, but it's annoying the hell out of me and is edging towards "bug" rather than "feature" in my mind. It also appears that there is no way of getting around it. You can edit /modules/blocks/block.admin.inc to force Drupal to show the blocks page in the chosen admin theme. BUT whichever changes you then make will not be transferred to the default theme, as Drupal treats each theme separately and each theme can have different block layouts. :x function block_admin_display($theme = NULL) { global $custom_theme; // If non-default theme configuration has been selected, set the custom theme. // $custom_theme = isset($theme) ? $theme : variable_get('theme_default', 'garland'); // Display admin theme $custom_theme = variable_get('admin_theme', '0'); // Fetch and sort blocks $blocks = _block_rehash(); usort($blocks, '_block_compare'); return drupal_get_form('block_admin_display_form', $blocks, $theme); } Can anyone help? the only thing I can think of is to push the $content area well below the areas where the image appear and use blocks only for content display. Thanks!

  • AS3 trouble instantiating Document Class of loaded SWF

    - by Marcy Sutton
    I am loading one swf into another using the Loader class, but when the child swf finishes loading and is added to the display list, its Document Class is not instantiated. I have a few trace statements should execute when the object is created. When I compile the child SWF on its own, the Document Class runs as expected. So I'm wondering... how do I associate a child SWF's Document Class with Loader.content? // code in parent SWF's Document Class (Preloader) public function Preloader(){ swfLoader = new Loader(); swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderDone); swfLoader.load(new URLRequest("mainmovie.swf")); } private function loaderDone(e:Event):void { // Add Loader.content to new Sprite mainMovie = Sprite(e.target.content); mainMovie.alpha = 0; swfLoader = null; addChildAt(mainMovie, 0); mainMovie.addEventListener(Event.ADDED_TO_STAGE, mainMovieAddedListener); } // functions in MainMovie.as not ever running, // even though it is listed as the child SWF's Document Class Cheers!
