  • Return user to original page after logging in (rails session mgmt)

    - by keruilin
    I'm looking for some general guidance as to how to return a user back to the original page they were viewing after trying to log-in. The way I have the site setup now is that if a user visits the Store page, for example, and then clicks the login button in the upper right, the user is returned to the default landing page. Any help would be greatly appreciated!

  • mySQL JOIN wont return results with 0 count

    - by MPC
    SELECT categories.*, COUNT(categoryID) AS kritCount FROM categories AS categories LEFT JOIN krits ON categories.id = categoryID WHERE (krits.approved = '1') GROUP BY categories.id So this works great except that it does not return a category that has a 0 count of krits in the category. It will if I remove the WHERE statement but I need the WHERE to only select the krits where the field approved = 1

    - by Pauff
    I have a class that has a vector of objects. What do I need to do to return one of this objects and change it outside the class, keeping the changings? Is it possible to do with regular pointers? Is there a standard procedure? (And yes, my background is in Java.)

  • Return all users from group(s) specified as comma delimited value

    - by todor
    I have the following two table scenario: users id groups 1 1,2,3 2 2,3 3 1,3 4 3 and groups id 1 2 3 How do I return the IDs of all users that belong to group 2 and 1 for example? Should I look into join, a helper group_membership table or function to separate the comma delimited group IDs to get something like this: group_membership user_id group_id 1 1 1 2 1 3 2 2 2 3 ... ...

  • Give WPF design mode default objects

    - by Janko R
    In my application I have <Rectangle.Margin> <MultiBinding Converter="{StaticResource XYPosToThicknessConverter}"> <Binding Path="XPos"/> <Binding Path="YPos"/> </MultiBinding> </Rectangle.Margin> The Data Context is set during runtime. The application works, but the design window in VS does not show a preview but System.InvalidCastException. That’s why I added a default object in the XYPosToThicknessConverter which is ugly. class XYPosToThicknessConverter : IMultiValueConverter { public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { // stupid check to give the design window its default object. if (!(values[0] is IConvertible)) return new System.Windows.Thickness(3, 3, 0, 0); // useful code and exception throwing starts here // ... } } My Questions: What does VS/the process that builds the design window pass to XYPosToThicknessConverter and what is way to find it out by myself. How do I change my XAML code, so that the design window gets its default object and is this the best way to handle this problem? I’m using VS2010RC with Net4.0

  • What do you need to implement to provide a Content Set for an NSArrayController?

    - by whuuh
    Heys, I am writing something in Xcode. I use Core Data for persistency and link the view and the model together with Cocoa Bindings; pretty much your ordinary Core Data application. I have an array controller (NSArrayController) in my Xib. This has its managedObjectContext bound to the AppDelegate, as is convention, and tracks an entity. So far so good. Now, the "Content Set" biding of this NSArrayController limits its content set (as you'd expect), by a keyPath from the selection in another NSArrayController (otherAc.selection.detailsOfMaster). This is the usual way to implement a Master-Detail relationship. I want to variably change the key path at runtime, using other controls. This way, I sould return a content set that includes several other content sets, which is all advanced and beyond Interface Builder. To achieve this, I think I should bind the Content Set to my AppDelegate instead. I have tried to do this, but don't know what methods to implement. If I just create the KVC methods (objectSet, setObjectSet), then I can provide a Content Set for the Array Controller in the contentSet method. However, I don't think I'm binding this properly, because it doesn't "refresh". I'm new to binding; what do I need to implement to properly update the Content Set when other things, like the selection in the master NSArrayController, changes?

  • "2d Search" in Solr or how to get the best item of the multivalued field 'items'?

    - by Karussell
    The title is a bit awkward but I couldn't found a better one. My problem is as follows: I have several users stored as documents and I am storing several key-value-pairs or items (which have an id) for each document. Now, if I apply highlighting I can get the first n items. If you have several hundreds of such items this highlighting is necessary and works nicely. But there are two problems: The highlighted text won't contain the id and so retrieving additional information of the highlighted item text is ugly. E.g. you need to store the id in the text so that the highlighter returns it. Adding the id to the hl.fl parameter does not help. You will not get the most relevant n-items. You will get the first n items ... So how can I find the best items of a documents with multiple such items? I will now add my own findings as answers, but as I will point out. Each of them has its drawbacks. Hopefully anyone of you can point me to a better solution.

  • ASP.NET MVC3 ValueProvider drops string input to a double property

    - by Daniel Koverman
    I'm attempting to validate the input of a text box which corresponds to a property of type double in my model. If the user inputs "foo" I want to know about it so I can display an error. However, the ValueProvider is dropping the value silently (no errors are added to the ModelState). In a normal submission, I fill in "2" for the text box corresponding to myDouble and submit the form. Inspecting controllerContext.HttpContext.Request.Form shows that myDouble=2, among other correct inputs. bindingContext.ValueProvider.GetValue("myDouble") == 2, as expected. The bindingContext.ModelState.Count == 6 and bindingContext.ModelState["myDouble"].Errors.Count == 0. Everything is good and the model binds as expected. Then I fill in "foo" for the text box corresponding to myDouble and submitted the form. Inspecting controllerContext.HttpContext.Request.Form shows that myDouble=foo, which is what I expected. However, bindingContext.ValueProvider.GetValue("myDouble") == null and bindingContext.ModelState.Count == 5 (The exact number isn't important, but it's one less than before). Looking at the ValueProvider, is as if myDouble was never submitted and the model binding occurs as if it wasn't. This makes it difficult to differentiate between a bad input and no input. Is this the expected behavior of ValueProvider? Is there a way to get ValueProvider to report when conversion fails without implementing a custom ValueProvider? Thanks!

  • Pass value of a field to Silverlight ConverterParameter

    - by eidylon
    Hi all, I'm writing my very first Silverlight app. I have a datagrid with a column that has two labels, for the labels, i am using an IValueConverter to conditionally format the data. The label's "Content" is set as such: Content="{Binding HomeScore, Converter={StaticResource fmtshs}}" and Content="{Binding AwayScore, Converter={StaticResource fmtshs}}" The Convert method of my IValueConverter is such: Public Function Convert( ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert Dim score As Long = value, other As Long = parameter Return If(score < 0, "", If(score - other > 5, (other + 5).ToString, score.ToString) ) End Function So what i want to do is in the converter for HomeScore, i want to pass AwayScore to the ConverterParameter, and for AwayScore i want to pass the HomeScore to the converter. In the converter for either score i need to be able to know the value of the other score for formatting purposes. But i cannot figure out the syntax for binding the ConverterParameter to another field. I've tried the following: Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter=AwayScore}" Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter={AwayScore}}" Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter={Binding AwayScore}}" But none of those seem to work. How do i pass a field value to the ConverterParameter?

  • How to add a default value to a custom ASP.NET Profile property

    - by mr.moses
    I know you can add defaultValues using the web.config like this: <profile> <properties> <add name="AreCool" type="System.Boolean" defaultValue="False" /> </properties> </profile> but I have the Profile inherited from a class: <profile inherits="CustomProfile" defaultProvider="CustomProfileProvider" enabled="true"> <providers> <clear /> <add name="CustomProfileProvider" type="CustomProfileProvider" /> </providers> </profile> Heres the class: Public Class CustomProfile Inherits ProfileBase Public Property AreCool() As Boolean Get Return Me.GetPropertyValue("AreCool") End Get Set(ByVal value As Boolean) Me.SetPropertyValue("AreCool", value) End Set End Property End Class I don't know how to set the default value of the property. Its causing errors because without a default value, it uses an empty string, which cannot be converted to a Boolean. I tried adding <DefaultSettingValue("False")> _ but that didn't seem to make a difference. I'm also using a custom ProfileProvider (CustomProfileProvider).

  • WPF ComboBox IsSynchronised Default Value

    - by LnDCobra
    I am trying to display a default value (or even NO value) when selected index is -1, or selecteditem is null. This normally works perfectly fine but when I enable IsSynchronizedWithCurrentItem and set it to True, the first value in my DataTable gets displayed. How can I have both IsSynchronizedWithCurrentItem ="True" and show no/default value when it is loaded. My Combo Box XAML: <GroupBox Name="ClientGroup" Header="Client" Margin="63,182,0,177" FontSize="14" HorizontalAlignment="Left" Width="298"> <ComboBox Name="Supplier" Grid.IsSharedSizeScope="True" ItemsSource="{Binding}" IsEditable="True" Text="Please Choose..." TextSearch.TextPath="CompanyName" IsSynchronizedWithCurrentItem="True" Height="23" VerticalAlignment="Top" Margin="0,6,6,0" FontSize="11" StaysOpenOnEdit="True"> <ComboBox.ItemTemplate> <DataTemplate> <Grid Margin="0,5,0,5"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" SharedSizeGroup="CompanyName" /> <ColumnDefinition Width="Auto" SharedSizeGroup="EIC" /> </Grid.ColumnDefinitions> <TextBlock Text="{Binding CompanyName}" Grid.Column="0" /> <TextBlock Text="{Binding EIC, StringFormat=' ({0})'}" Grid.Column="1" FontFamily="Courier New" FontWeight="Bold" FontSize="12" /> </Grid> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> </GroupBox> My CS code behind: ClientGroup.DataContext = (new CompanyDealsDataSetTableAdapters.CompanyTableAdapter()).GetData(); When I start my application it automatically selects the first row in my data table. It works as expected when I remove IsSynchronizedWithCurrentItem. Any ideas?

  • How to I get the value of a custom soap header in WCF

    - by Jason Coyne
    I have created a custom soap header, and added it into my message via IClientMessageInspector public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel) { var header = new MessageHeader<AuthHeader>(); header.Content = new AuthHeader(Key); header.Actor = "Anyone"; var header2 = header.GetUntypedHeader("Auth", "xWow"); request.Headers.Add(header2); return null; } [DataContract(Name="Auth")] public class AuthHeader { public AuthHeader(string key) { this.Key = key; } [DataMember] public string Key { get; set; } } I also have an IDispatchMessageInspector, and I can find the correct header in the list. However, there is no value. I know that the value went across the wire correctly, because the message string is correct <s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">\r\n <s:Header>\r\n <Auth s:actor=\"Anyone\" xmlns=\"xWow\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">\r\n <Key xmlns=\"http://schemas.datacontract.org/2004/07/xWow.Lib\">HERE IS MY KEY VALUE!!!!</Key>\r\n </Auth>\r\n <To s:mustUnderstand=\"1\" xmlns=\"http://schemas.microsoft.com/ws/2005/05/addressing/none\">http://localhost:26443/AuthService.svc</To>\r\n <Action s:mustUnderstand=\"1\" xmlns=\"http://schemas.microsoft.com/ws/2005/05/addressing/none\">http://tempuri.org/IAuthService/GetPayload</Action>\r\n </s:Header>\r\n <s:Body>\r\n <GetPayload xmlns=\"http://tempuri.org/\" />\r\n </s:Body>\r\n</s:Envelope>" But there does not seem to be any property to retrieve this value. The MessageHeaderInfo class has Actor, etc, but nothing else useful I can find. On the client side I had to convert between Header and Untyped header, is there an equivalent operation on the server?

  • Setting ItemTemplate based on CheckBox value

    - by ph0enix
    I have a DataTemplate which contains a CheckBox and ListBox. When the CheckBox is checked, I want to change the ItemTemplate property on the ListBox to change the appearance of each item. Right now, it looks like this: <DataTemplate DataType={x:Type MyViewModel}> <DockPanel> <CheckBox DockPanel.Dock="Bottom" Content="Show Details" HorizontalAlignment="Right" IsChecked="{Binding ShowDetails}" Margin="0 5 10 5" /> <ListBox ItemsSource="{Binding Items}" ItemTemplate="{StaticResource SimpleItemTemplate}" Margin="10 0 10 5"> <ListBox.Triggers> <DataTrigger Binding="{Binding ShowDetails}" Value="True"> <Setter Property="ItemTemplate" Value="{StaticResource DetailedItemTemplate}" /> </DataTrigger> </ListBox.Triggers> </ListBox> </DockPanel> </DataTemplate> However, when I try to compile, I get the following error messages: Value 'ItemTemplate' cannot be assigned to property 'Property'. Invalid PropertyDescriptor value. and Cannot find the static member 'ItemTemplateProperty' on the type 'ContentPresenter'. I'm still fairly new to WPF, so perhaps there is something I'm not quite understanding?
