问题 I have created a self-signed SSL certificate via C# (bouncycastle). It shows up in the local computer / personal store and looks exactly like the already existing localhost certificate from Microsoft. If I show the properties, it says: SSL Certificate add failed, Error: 1312 A specified logon session does not exist. It may already have been terminated. However, if I want to register this certificate via netsh, I get an error: netsh.exe http add sslcert ipport=0.0.0.0:{0} certhash={1} appid={2

问题 somehow I am going in circles here. Please forgive me if the answer to this question is obvious. I want to react to changed properties in the ViewModel in the View. When the properties (bool) change the View should start an animation (BeginStoryBoard). Actually in my application there are 4 of these properties each with its own name in the VM and two desired animations each (hide/show) for the respective 4 container view elements. When setting these Triggers (tried DataTrigger/Trigger

问题 Something like: <TextBlock Text="{Binding Text,Converter={StaticResource ccc},ConverterParameter=PersonName}"/> when Person name is Property of the class for example. Update: I've seen a solution that tells to inherit from DependencyObject and to implement IValueConverter. I want to know if there is something simpler. 回答1: The answer is straight-forward, but not what you want to hear. You can only target a binding at DependencyProperty on a DependencyObject. Binding does not inherit from DO,

问题 Lately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes). So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp? Thanks in advance 回答1: <Injectors target="

问题 I have using a DelegateCommand and i want to pass the UserControl with Command. #region OpenViewCommand private DelegateCommand<UserControl> _openViewCommand; public ICommand OpenViewCommand { get { if (_openViewCommand == null) _openViewCommand = new DelegateCommand<UserControl>(new Action<UserControl>(OpenView)); return _openViewCommand; } } public void OpenView(UserControl ViewName) { UserControl ctrl = (UserControl)ViewName; JIMS.Controls.Message.Show(ViewName.ToString()); } #endregion

问题 I am going through the Sams book "Teach Yourself WPF in 24 Hours". At one point the authors show how you can bind a ListBox's selected-item value to a property. I get that, it's pretty straightforward. But when I try to create my own ListBox control with my own ListBoxItems, I can't seem to get it to work. The ListBox that works uses a system collection as its ItemsSource property: <ListBox x:Name="FontList" DockPanel.Dock="Left" ItemsSource="{x:Static Fonts.SystemFontFamilies}" Width="160" /

问题 I have a dependency property defined in my window as below: public static readonly DependencyProperty IsGenericUserProperty = DependencyProperty.Register("IsGenericUser", typeof (bool), typeof (MainWindow)); public bool IsGenericUser { get { return (bool) GetValue(IsGenericUserProperty); } set { SetValue(IsGenericUserProperty, value); } } On my window's constructor I set the data context of the container holding the button: QuickListButtonsStackPanel.DataContext = this; I am binding the

问题 In my Application there is a Service and an AccessibilityService . Now the Service is bound by the accessibility Service in order to receive information. My Service periodically checks if the AccessibilityService is enabled, and if it is not, it sends a notification to the user that it has to enable it. Once enabled, AccessibilityService starts to work. First it binds to my Service , and after, it begins to send information. The problem is if AccessibilityService crashes. It remains enabled
