binding

问题 MethodInfo method = typeof(T).GetMethod("Parse", new[] { typeof(string) }); parse = Delegate.CreateDelegate(typeof(Func<T,string>), method); T is a float in this case. However I am getting a Error binding to target method. Parse I believe is a static method. I have looked at other examples, but I can not figure out why it is not binding. 回答1: you have to swap T and string because the method returns a T not a string . I replaced T with float and following code works for me: MethodInfo method =

问题 I have a WPF application with a ListBox (called listMyItems) which is successfully bound to a class of MyItems that I created. I have a List of MyItems called currentMyItems which is then assigned as ItemSource to the ListBox. It all works fine, if I add an item to the currentMyItems it pops up on the list, etc. The problem occurs when I try to remove the selected item in the ListBox. This is the code that I use: currentMyItems.Remove((MyItem)listMyItems.SelectedItem); The item disappears

问题 So I have a class I want to bind to: public class Awesome { public bool OptionA1 { get; set; } public bool OptionA2 { get; set; } public bool OptionB1 { get; set; } public bool OptionB2 { get; set; } } When I expose this class in my GUI, I have two radio buttons (called radioButtonA and radioButtonB) which let the user pick between groups A and B, and I have two checkboxes to let the user change A1/A2 and B1/B2 respectively depending on which radiobutton ischecked. The logic in the class

问题 (define make (lambda (x) (lambda (y) (cons x (list y))))) (let ((x 7) (p (make 4))) (cons x (p 0))) I'm new to Scheme and functional program, so I am a bit clunky with walking through programs, but I get that if I used deep binding this program will return (7 4 0). Makes sense. What would this program do using shallow binding? I get this may sound dumb but is the p in the line with cons a redefinition? So in that case, we would return (7 0)? Basically, I understand the concept of deep v.

问题 I have inherited a project that uses JGoodies Binding to connect the domain model to the GUI. However, there are some inconsistencies that I have found which also cause some bugs. In this concrete case, the GUI is represented by two radio buttons and a label. Depending on which button is selected, the label should display a certain image. The buttons are bound to different Enum values, like this: AbstractValueModel enumSelectionModel = presentationModel.getModel("selection"); radioBtn1 =
