dispatch

问题 I am new in using Bot Builder Framework. I was following this tutorial from Microsoft https://docs.microsoft.com/en-us/azure/cognitive-services/qnamaker/tutorials/integrate-qnamaker-luis. I am using the code from GitHub(NLP-with-dispatch) and set up all the necessary requirements DISPATCH, Luis, Qnamaker, etc. But after running the code using the bot emulator I got this error message. "No such host is known". BTW, I already updated the appsettings.json and bot config. Anyone experience this?

问题 i have implemented textToSpeech in my project and want to display an alertview while text is spoken. here i am calling the methods for textToSpeech: //-----before TTS starts i try to display alertView with Cancelbutton //[self performSelectorOnMainThread:@selector(alertWhileTTS) withObject:nil waitUntilDone:YES]; //gray view and no alertview //[self performSelector:@selector(alertWhileTTS)]; //gray view and no alertview //[self alertWhileTTS]; //gray view and no alertview //this part here is

问题 Consider the following code: internal static class Program { public static string ExtensionMethod(this string format, dynamic args) { return format + args.ToString(); } private static void Main() { string test = "hello "; dynamic d = new { World = "world" }; // Error CS1973 'string' has no applicable method named 'ExtensionMethod' // but appears to have an extension method by that name. // Extension methods cannot be dynamically dispatched. // Consider casting the dynamic arguments or calling

问题 I'm new to assembly and I'm trying to figure out how C++ handles dynamic dispatch in assembly. When looking through assembly code, I saw that there were 2 unusual calls: call _Znwm call _ZdlPv These did not have a subroutine that I could trace them to. From examining the code, Znwm seemed to return the address of the object when its constructor was called, but I'm not sure about that. ZdlPv was in a block of code that could never be reached (it was jumped over). C++: Fruit * f; f = new Apple(

问题 I have this simple method which calculates the weighted average of a collection of vectors function meanw{T <: Number}(x::AbstractArray{AbstractVector{T}, 1}, w::AbstractVector{T}) x̄ = sum(x .* w) x̃ = map(z -> z - x̄, x) x̄, x̃ end but the dispatch cannot match my method when I try to use it. ERROR: `meanw` has no method matching meanw(::Array{Array{Float64,1},1}, ::Array{Float64,1}) I suspect that I have misunderstood how to use type restrictions when there is nesting involved. How should

问题 This may be a stupid question, I suspect I know the answer (no) because I seem to be hitting a wall here. Given I have a collection of objects derived from certain class: class BaseClass; class DerivedA: public BaseClass; class DerivedB: public BaseClass; class DerivedC: public BaseClass; std::vector<BaseClass> myCollection; I want to call a method depending on the types of the specific class: class Processor { void doSomething(DerivedA a, DerivedB b); void doSomething(DerivedA a, DerivedC c)

问题 I'm trying to speed up a variable-bitwidth integer compression scheme and I'm interested in generating and executing assembly code on-the-fly. Currently a lot of time is spent on mispredicted indirect branches, and generating code based on the series of bitwidths as found seems to be the only way avoid this penalty. The general technique is referred to as "subroutine threading" (or "call threading", although this has other definitions as well). The goal is to take advantage of the processors

问题 I´m trying to set up an iteration for downloading images. The whole process works, but taking a look in the console´s output, something seems to be wrong. func download() { let logos = [Logos]() let group = DispatchGroup() logos.forEach { logo in print("enter") group.enter() if logo?.data == nil { let id = logo?.id as! String if let checkedUrl = URL(string: "http://www.apple.com/euro/ios/ios8/a/generic/images/\(id).png") { print(checkedUrl) LogoRequest.init().downloadImage(url: checkedUrl) {

问题 Given the following Haskell code snapshot: class Foo a where bar :: a -> ... quux :: a -> ... ... Where the value of a is determined at runtime - the class dispatches on this value. I'm assuming that the compiler can statically check the types at compile-time, and ensure that no invalid types can dispatch on it. Now if we compare this to a dynamic dispatch in Java: interface Flippable { Flippable flip(); } class Left implements Flippable { Right flip(); } class Right implements Flippable {

问题 I am trying to create a loop like this: while (TRUE){ dispatch_after(...{ <some action> }); } After a viewDidLoad. The idea is to repeat the dispatch_after repeatedly. The dispatch_after waits two seconds before doing the action. This does not work - the screen just blanks? Is it stuck in looping or ...? 回答1: The dispatch_after(...) call returns immediately no matter when it is scheduled to run. This means that your loop is not waiting two seconds between dispatching them. Instead you are
