dynamic

问题 I'm not really expert in VBA and I have a problem with my code and I don't know how to solve it. (The code is from: http://siddharthrout.wordpress.com/2011/07/29/excel-data-validationcreate-dynamic-dependent-lists-vba/) I'm working with 8 dynamic dependent lists, and I thought the best way to automate the process and avoid to modify the macro in a future if I modify the lists was a VBA code. Trying to find the correct code, I'm just working with to lists. For after, apply it for all lists. I

问题 spent some time again with the scripting interface of my app. i guess i now have an advanced dlr problem here. I have a python script I have an .NET object [o1] I call a method on the python script from .NET via Iron Python. The python code creates an object [o2] The python code calls an method on object [o1] passing [o2] as an argument (Via subclassing DynamicMetaObject) In the .NET code of the o1-method i want to dynamically call methods on o2 For example i could do that via ((dynamic)o2)

问题 I have a set of so called fluent interfaces, so I can use syntax like this: a.With("abc").Do("this").Then("that); Each method returns an object cast to a corresponding interface. At design time I can use Intellisense to easily navigate between API methods. However I can no longer do it if I cast one of the arguments to a dynamic: a.With((dynamic)"abc").Do("this").Then("that); Not only I lose Intellisense at design time, this cast affects runtime execution: all subsequent calls after With

问题 In the example syntax below, how can I add each element to a new array instead of printing? I am unsure how to do such as I would not know the size of the array, since it could be 0 (no need to ever initialize the array) or it could be the Ubound of the array it is iterating. Option Compare Database Option Explicit Function TestIt() Dim animalarray As Variant, xyz As Variant animalarray = Array("Cat", "Cow", "Camel", "Dire Wolf", "Dog", "Coyote", "Rabbit", "Road runner", "Cougar") For Each

问题 RESOLVED Issue was that onChange took a wrong value. public onChange = (e:any, key:any) => { this.setState({ [key]: e.target.value }); }; I seem to have trouble getting rid of an error when entering data into my form. I am using TSX React. The goal is to be able to create a form dynamically. The issue I kept running into is that the value of my inputs cannot be read. I was wondering if anyone could look at my code and maybe spot my mistake, I am pretty clueless at this point. I am using the

问题 So let's say I have an acyclic, directed graph G with nodes a0, a1, a2, b0, b1, b2, c0, c1, c2 and I know both the outgoing distance for each node to any of it's neighbors. What algorithm can I use to find the longest path between any two nodes that is less than a given length? EDIT: I have looked at the Wikipedia page for the Longest path problem but I don't know whether to use the algorithm outlined in the 'Acyclic graphs and critical paths' section or the one in the 'Parameterized

问题 As far as I've searched it appears to be impossible to load modules (=plugins/libraries?) dynamically (I'm very new to React Native..). What I'd like to accomplish is to let the user of the app load additional functions as she/he desires. Example: A user wants to add a music plugin to the app. Intuitively, I'd long for something like dynamic library loading. The user would fetch the library, it'll be loaded into the code and can then be executed. However, in React Native it seems like there

问题 In python, to dynamically load a module, you can simply use the _____import_____ statement and assign the module to a variable, I.e(from the docs): spam = __import__('spam', globals(), locals(), [], -1) I have used this several times in python in order to simulate dynamic module loading/unloading, because to "unload" the module, you can simply remove all references to it, I.e: spam = None Is there an equivalent to this in Ruby? I looked at a few other questions (this, this, and this), but I

问题 I adapted a roll-your-own Input box based on this. I modified the code to the following: using System; using System.Windows.Forms; public static class PromptForText { public static string ShowDialog(string caption, string text) { Form prompt = new Form(); prompt.Width = 280; prompt.Height = 150; prompt.Text = caption; Label textLabel = new Label() { Left = 16, Top = 20, Width = 240, Text = text }; TextBox textBox = new TextBox() { Left = 16, Top = 40, Width = 240 }; Button confirmation = new
