  • PLPGSQL : Return a record from function executed by INSERT/UPDATE rule

    - by seas
    Do the following scheme for my database: create sequence data_sequence; create table data_table { id integer primary key; field varchar(100); }; create view data_view as select id, field from data_table; create function data_insert(_new data_view) returns data_view as $$declare _id integer; _result data_view%rowtype; begin _id := nextval('data_sequence'); insert into data_table(id, field) values(_id, _new.field); select * into _result from data_view where id = _id; return _result; end; $$ language plpgsql; create rule insert as on insert to data_view do instead select data_insert(new); Then type in psql: insert into data_view(field) values('abc'); Would like to see something like: id | field ----+--------- 1 | abc Instead see: data_insert ------------- (1, "abc") Is it possible to fix this somehow? Thanks for any ideas.

  • PriorityQueue update problems

    - by Bharat
    After going through a bunch of questions here on SO, I still have no idea what exactly is going wrong with my code and would appreciate some help. I'm trying to implement a priority queue based on f-costs for an A* algorithm, and while the algorithm works fine for short pathfinding distances, it seems to go wrong when there's an obstacle or when the distance between start and goal points is greater than about 30 squares (although sometimes it screws up for less too). while(!m_qOpenList.isEmpty()) { m_xCurrent=m_qOpenList.poll(); m_xCurrent.setBackground(Color.red); m_qClosedList.add(m_xCurrent); if(m_xCurrent.getStatus()==2) { System.out.println("Target Reached"); solved=true; break; } iX=m_xCurrent.getXCo(); iY=m_xCurrent.getYCo(); for(i=iX-1;i<=iX+1;i++) for(j=iY-1;j<=iY+1;j++) { if(i<0||j<0||i>m_iMazeX||j>m_iMazeX||(i==iX&&j==iY) || m_xNode[i][j].getStatus()==4|| m_qClosedList.contains(m_xNode[i][j])) continue; m_xNode[i][j].score(m_xCurrent,m_xGoal); m_qOpenList.add(m_xNode[i][j]); } } It's quite rudimentary as I'm just trying to get it to work for now. m_qOpenList is the PriorityQueue. The problem is that when I debug the program, at some point (near an obstacle), a Node with a fcost of say 84 has higher priority than a node with an fcost of 70. I am not attempting to modify the values once they're on the priority queue. You'll notice that I add at the end of the while loop (I read somewhere that the priorityqueue reorders itself when stuff is added to it), and poll right after that at the beginning. Status of 2 means the Node is the goal, and a status of 4 means that it is unwalkable. public int compareTo(Node o) { if(m_iF<o.m_iF) return -1; if(m_iF>o.m_iF) return 1; return 0; } And that's the compareTo function. Can you see a problem? =(

  • WPF Using commands to slow to update UI controls

    - by toni
    Hi, I bind a command to a button through command property and doing a command binding in the page it is placed. In execute method I create an instance of a class that contains the background worker and I start it (this is a long task). The background worker (bw) class contains a variable isRunning that it is set to true before DoWork method is executed and to false when RunWorkerCompleted is executed. So from the code behind of the page where button is placed, in CanExecute method I set e.canExecute to true if bw is no running (isRunning = false), and e.canExecute to false if isRunning = true. WHen I press the button, it launch bw process for a long time and the button gets disabled. Ok this is correct, but when background worker (bw) finishes, the button doesn't returns to enabled until I press it again. When it is disabled and I press (when bw is finished) it gets enabled. Why the button is not returning automatically to enabled at the end of the bw? my code snippet: <Page x:Class="GParts.Pages.MyPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes; assembly=PresentationFramework.Aero" xmlns:local="clr-namespace:GParts" Loaded="Page_Loaded" Unloaded="Page_Unloaded" Height="Auto"> <Page.CommandBindings> <CommandBinding Command="{x:Static local:Pages.MyPage.rcmd}" Executed="CommandBinding_Executed" CanExecute="CommandBinding_CanExecute"/> </Page.CommandBindings> <...> <Button Command="{x:Static local:Pages.MyPage.rcmd}" /> <...> </Page> The code behind of the page: namespace GParts.Pages { public partial class MyPage : Page { public static RoutedCommand rcmd = new RoutedCommand(); private cBgWorker bw; <...> // ExecutedRoutedEventHandler for the custom button remove all command. private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e) { // get an isntance of the background worker class bw = new cBgWorker(); // start the long task bw.StartTask(); } // CanExecuteRoutedEventHandler for the custom button remove all command. private void CommandBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e) { // bw is the instance of background worker class if (bw == null) { e.CanExecute = true; } else { e.CanExecute = !bw.isRunning;// isRunning indicates if bw is //executing now } } <...> } // end class } // end namespace

  • FireFox Toolbar Prefwindow unload/acceptdialog Event to Update the toolbar

    - by Mark
    Hi all, I'm trying to develop a firefox toolbar ;) so my structure is In the options.xul is an PrefWindow which i'm opening over an <toolbarbutton oncommand="esbTb_OpenPreferences()"/> function esbTb_OpenPreferences() { window.openDialog("chrome://Toolbar/content/options.xul", "einstellungen", "chrome,titlebar,toolbar,centerscreen,modal", this);} so in my preferences i can set some checkboxes which indicates what links are presented in my toolbar. So when the preferences window is Closed or the "Ok" button is hitted I want to raise an event or an function which updates via DOM my toolbar. So this is the function which is called when the toolbar is loaded. It sets the links visibility of the toolbar. function esbTB_LoadMenue() { var MenuItemNews = document.getElementById("esbTb_rss_reader"); var MenuItemEservice = document.getElementById("esbTb_estv"); if (!(prefManager.getBoolPref("extensions.esbtoolbar.ShowNews"))) { MenuItemNews.style.display = 'none'; } if (!(prefManager.getBoolPref("extensions.esbtoolbar.ShowEservice"))) { MenuItemEservice.style.display = 'none'; } } So I tried some thinks like adding an eventlistener to the dialog which doesn't work... in the way I tried... And i also tried to hand over the window object from the root window( the toolbar) as an argument of the opendialog function changed the function to this. function esbTB_LoadMenue(RootWindow) { var MenuItemNews = RootWindow.getElementById("esbTb_rss_reader"); var MenuItemEservice = RootWindow.getElementById("esbTb_estv");} And then tried to Access the elements over the handover object, but this also not changed my toolbar at runtime. So what i'm trying to do is to change the visibile links in my toolbar during the runtime and I don't get it how I should do that... thanks in advance

  • Lobo Cobra HtmlPanel does not update GUI after JavaScript action

    - by Markus Lausberg
    HI, I started implementing a HTML Browser in Swing. I want to use the Lobo Cobra toolkit because this toolkit inclused a renderer and parser for CSS and JavaScript. The pages are looking very nice and it is easy to use (one class implementation to show a html page). I want to show HTML pages in swing which can show javascript generated and modified objects, like a flashing circle. As far as i know, the cobra toolkit can show static javascript commands like 'document.write' or closwWindow() implementations, but not updating the GUI from a JavaScript. Did someone works with Lobo Cobra Toolkit before and give me some sample code or tips for showing HTML pages with animated JavaScript objects inside.

  • Rails 3.2 Ajax Update Div when Text Field Populated

    - by ctilley79
    In the end I would like a text field that passes a client_id to the partial. I would like to do this asynchronously so the shipment_products partial would dynamically change when the textfield value was updated. What is the best way to do this? In index.html.erb <!-- Text Field Here--> <div id="available_products"> <%= render "shipment_products" %> </div> In _shipment_products.html.erb <div id="shipment_products_container"> <h3>Assign Products to Ship<\h3> <ul class="shipment_products" id="shipment_products"> <% Product.by_client(client_id).each do |product|%> <!-- TextField value passed here --> <%= content_tag_for :li, product, :value => product.id do %> <%= hidden_field_tag("shipment[product_ids][]", product.id) %> <%= product.product_name %> <% end %> <% end %> <\ul> </div> This is similar to what I want in the end.

  • Silverlight DataGrid's sort by column doesn't update programmatically changed cells

    - by David Seiler
    For my first Silverlight app, I've written a program that sends user-supplied search strings to the Flickr REST API and displays the results in a DataGrid. Said grid is defined like so: <data:DataGrid x:Name="PhotoGrid" AutoGenerateColumns="False"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="Photo Title" Binding="{Binding Title}" CanUserSort="True" CanUserReorder="True" CanUserResize="True" IsReadOnly="True" /> <data:DataGridTemplateColumn Header="Photo" SortMemberPath="ImageUrl"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" VerticalAlignment="Center"> <TextBlock Text="Click here to show image" MouseLeftButtonUp="ShowPhoto"/> <Image Visibility="Collapsed" MouseLeftButtonUp="HidePhoto"/> </StackPanel> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> </data:DataGrid.Columns> </data:DataGrid> It's a simple two-column table. The first column contains the title of the photo, while the second contains the text 'Click here to show image'. Clicks there call ShowPhoto(), which updates the Image element's Source property with a BitmapImage derived from the URI of the Flickr photo, and sets the image's visibility to Visible. Clicking on the image thus revealed hides it again. All of this was easy to implement and works perfectly. But whenever I click on one of the column headers to sort by that column, the cells that I've updated in this way do not change. The rest of the DataGrid is resorted and updated appropriately, but those cells remain behind, detached from the rest of their row. This is very strange, and not at all what I want. What am I doing wrong? Should I be freshening the DataGrid somehow in response to the sort event, and if so how? Or if I'm not supposed to be messing with the contents of the grid directly, what's the right way to get the behavior I want?

    - by Barry
    I have run into a problem which have searched and tried everything i can to find a solution but to no avail. I am using the same repository and context throughout the process I have a booking entity and a userExtension Entity Below is my image i then get my form collection back from my page and create a new booking public ActionResult Create(FormCollection collection) { Booking toBooking = new Booking(); i then do some validation and property assignment and find an associated BidInstance toBooking.BidInstance = bid; i have checked and the bid is not null. finally i get the user extension file from the Current IPRINCIPAL USER as below UserExtension loggedInUser = m_BookingRepository.GetBookingCurrentUser(User); toBooking.UserExtension = loggedInUser; The Code to do the getUserExtension is : public UserExtension GetBookingCurrentUser(IPrincipal currentUser) { var user = (from u in Context.aspnet_Users .Include("UserExtension") where u.UserName == currentUser.Identity.Name select u).FirstOrDefault(); if (user != null) { var userextension = (from u in Context.UserExtension.Include("aspnet_Users") where u.aspnet_Users.UserId == user.UserId select u).FirstOrDefault(); return userextension; } else{ return null; } } It returns the userextension fine and assigns it fine. i originally used the aspnet_users but encountered this problem so tried to change it to the extension entity. as soon as i call the : Context.AddToBooking(booking); Context.SaveChanges(); i get the following exception and im completely baffled by how to fix it Entities in 'FutureFlyersEntityModel.Booking' participate in the 'FK_Booking_UserExtension' relationship. 0 related 'UserExtension' were found. 1 'UserExtension' is expected. then the final error that comes to the front end is: Metadata information for the relationship 'FutureFlyersModel.FK_Booking_BidInstance' could not be retrieved. Make sure that the EdmRelationshipAttribute for the relationship has been defined in the assembly. Parameter name: relationshipName.. But both the related entities are set in the booking entity passed thruogh PLEASE HELP Im at wits end with this

  • DataTrigger inside ControlTemplate doesn't update

    - by kennethkryger
    I have a ListBox that is bound to a list of CustomerViewModel-objects, that each has two dependency properties: - Name (string) - Description (string) - IsVisible (bool) (the IsVisible property is True by default and is reversed via the ToggleVisibility Command on the CustomerViewModel) I would like to display the Name and Description to the right of a Border-control, that is has a Transparent background when the IsVisible property is True and Green when the False. My problem is that the DataTrigger part of the code below doesn't work the way I want, because the Setter-part isn't triggered when the IsVisible is changed. What am I doing wrong? Here's my code: <UserControl.Resources> <Style x:Key="ListBoxStyle" TargetType="{x:Type ListBox}"> <Setter Property="Margin" Value="-1,-1,0,0" /> <Setter Property="BorderThickness" Value="0" /> <Setter Property="Background" Value="Transparent" /> <Setter Property="ItemContainerStyle" Value="{DynamicResource ListboxItemStyle}" /> <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled" /> </Style> <Style x:Key="ListboxItemStyle" TargetType="{x:Type ListBoxItem}"> <Setter Property="Background" Value="Transparent" /> <Setter Property="FocusVisualStyle" Value="{x:Null}" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type ListBoxItem}"> <Grid> <Border x:Name="border" Background="{TemplateBinding Background}" BorderBrush="#FFD4D6D5" BorderThickness="0,0,0,1"> <Grid Height="70" Margin="0,0,10,0"> <Grid.RowDefinitions> <RowDefinition Height="10" /> <RowDefinition Height="Auto" /> <RowDefinition /> <RowDefinition Height="10" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition /> </Grid.ColumnDefinitions> <Border x:Name="visibilityColumn" Grid.Row="0" Grid.Column="0" Grid.RowSpan="4" Background="Transparent" Width="4" Margin="0,0,4,0" /> <TextBlock x:Name="customerName" Grid.Row="1" Grid.Column="1" Foreground="#FF191919" FontWeight="Bold" Text="{Binding Name}" VerticalAlignment="Top" /> <TextBlock Grid.Row="2" Grid.Column="1" VerticalAlignment="Stretch" Text="{Binding Description}" TextWrapping="Wrap" Foreground="#FFB4B4B4" TextTrimming="CharacterEllipsis" /> </Grid> <Border.ContextMenu> <ContextMenu> <MenuItem Header="Edit..." /> <MenuItem Header="Visible" IsCheckable="True" IsChecked="{Binding IsVisible}" Command="{Binding ToggleVisibility}"/> </ContextMenu> </Border.ContextMenu> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background" Value="#FFEEEEEE" /> </Trigger> <Trigger Property="IsSelected" Value="True"> <Setter Property="Background" Value="#FFF5F5F5" /> <Setter TargetName="customerName" Property="Foreground" Value="Green" /> </Trigger> <DataTrigger Binding="{Binding IsVisible}" Value="False"> <!--If Value="True" the customerName Border shows up green!--> <Setter Property="Background" Value="Green" /> </DataTrigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <ListBox Style="{StaticResource ListBoxStyle}" ItemsSource="{Binding CustomerViewModels}" />

  • Calling SubmitChanges on DataContext does not update database.

    - by drasto
    In C# ASP.NET MVC application I use Link to SQL to provide data for my application. I have got simple database schema like this: In my controller class I reference this data context called Model (as you can see on the right side of picture in properties) like this: private Model model = new Model(); I've got a table (List) of Series rendered on my page. It renders properly and I was able to add delete functionality to delete Series like this: public ActionResult Delete(int id) { model.Series.DeleteOnSubmit(model.Series.SingleOrDefault(s => s.ID == id)); model.SubmitChanges(); return RedirectToAction("Index"); } Where appropriate action link looks like this: <%: Html.ActionLink("Delete", "Delete", new { id=item.ID })%> Also create (implemented in similar way) works fine. However edit does not work. My edit looks like this: public ActionResult Edit(int id) { return View(model.Series.SingleOrDefault(s => s.ID == id)); } [HttpPost] public ActionResult Edit(Series series) { if (ModelState.IsValid) { UpdateModel(series); series.Title = series.Title + " some string to ensure title has changed"; model.SubmitChanges(); return RedirectToAction("Index"); } I have controlled that my database has a primary key set up correctly. I debugged my application and found out that everything works as expected until the line with model.SubmitChanges();. This command does not apply the changes of Title property(or any other) against the database. Please help.

  • How to update QStandartItemModel without freezing the main UI

    - by user1044002
    I'm starting to learn PyQt4 and have been stuck on something for a long time now and can't figure it out myself: Here is the concept: There is a TreeView with custom QStandartItemModel, which gets rebuild every couple of seconds, and can have a lot (hundreds at least) of entries, there also will be additional delegates for the different columns etc. It's fairly complex and the building time for even plain model, without delegates, goes up to .3 sec, which makes the TreeView to freeze. Please advice me for the best approach on solving this. I was thing of somehow building the model in different thread, and eventually sending it to the TreeView, where it would just perform setModel() with the new one, but couldn't make that work. here is some code that may illustrate the problem a bit: from PyQt4.QtCore import * from PyQt4.QtGui import * import sys, os, re, time app = QApplication(sys.argv) REFRESH = 1 class Reloader_Thread(QThread): def __init__(self, parent = None): QThread.__init__(self, parent) self.loaders = ['\\', '--', '|', '/', '--'] self.emit(SIGNAL('refresh')) def run(self): format = '|%d/%b/%Y %H:%M:%S| ' while True: self.emit(SIGNAL('refresh')) self.sleep(REFRESH) class Model(QStandardItemModel): def __init__(self, viewer=None): QStandardItemModel.__init__(self,None) self.build() def build(self): stTime = time.clock() newRows = [] for r in range(1000): row = [] for c in range(12): item = QStandardItem('%s %02d%02d' % (time.strftime('%H"%M\'%S'), r,c)) row.append(item) newRows.append(row) eTime = time.clock() - stTime outStr = 'Build %03f' % eTime format = '|%d/%b/%Y %H:%M:%S| ' stTime = time.clock() self.beginRemoveRows(QModelIndex(), 0, self.rowCount()) self.removeRows(0, self.rowCount()) self.endRemoveRows() eTime = time.clock() - stTime outStr += ', Remove %03f' % eTime stTime = time.clock() numNew = len(newRows) for r in range(numNew): self.appendRow(newRows[r]) eTime = time.clock() - stTime outStr += ', Set %03f' % eTime self.emit(SIGNAL('status'), outStr) self.reset() w = QWidget() w.setGeometry(200,200,800,600) hb = QVBoxLayout(w) tv = QTreeView() tvm = Model(tv) tv.setModel(tvm) sb = QStatusBar() reloader = Reloader_Thread() tvm.connect(tvm, SIGNAL('status'), sb.showMessage) reloader.connect(reloader, SIGNAL('refresh'), tvm.build) reloader.start() hb.addWidget(tv) hb.addWidget(sb) w.show() app.setStyle('plastique') app.processEvents(QEventLoop.AllEvents) app.aboutToQuit.connect(reloader.quit) app.exec_()

  • Has there been a Firefox update recently?

    - by Rob Nicholson
    Trying again to ask a PROGRAMMING question because of the over-zealous closing off of what is equally a programming question before allowing the poster to clarify. The latest version of Firefox (v3.6.3) is breaking websites, mine included. I make heavy use of the Infragistic NetAdvantage controls. These, because of their heavy JavaScript reliance and occasional lack of quality control, tend to suffer through browser updates sometimes requiring a hotfix. So the question is... has there been a Firefox release recently that has either introduced a bug, tightening up of some standard, bug fix which might have broken a previous workaround (often the case) etc? I'm guessing around JavaScript but that's a guess hence the reason for asking a group of programmers...

  • Receiving DB update events in .NET from SQLite

    - by Dan Tao
    I've recently discovered the awesomeness of SQLite, specifically the .NET wrapper for SQLite at http://sqlite.phxsoftware.com/. Now, suppose I'm developing software that will be running on multiple machines on the same network. Nothing crazy, probably only 5 or 6 machines. And each of these instances of the software will be accessing an SQLite database stored in a file in a shared directory (is this a bad idea? If so, tell me!). Is there a way for each instance of the app to be notifiied if one instance updates the database file? One obvious way would be to use the FileSystemWatcher class, read the entire database into a DataSet, and then ... you know ... enumerate through the entire thing to see what's new ... but yeah, that seems pretty idiotic, actually. Is there such a thing as a provider of SQLite updates? Does this even make sense as a question? I'm also pretty much a newbie when it comes to ADO.NET, so I might be approaching the problem from the entirely wrong angle.

I want to be able to stretch an event that stretches over couple of days in a div that spans those days in the calendar. Basically I would like to know how to achieve what these guys have achieved with the event that stretches out from 21st to 22nd with the yellow div background. I have been trying to see how I can do it with PHP but I feel like I might be trying the wrong thing. Perhaps this is done with javascript?

  • Can you update/add records in SQL using a datagridview and LINQ to SQL
