call

问题 What are some alternatives to the x86 call instruction? Maybe something like a push of the return address then a jump? Also is their a command for obtaining the current position in memory? 回答1: CALL actually does this for you for example CALL my_func would do something like push ret_address jmp my_func and a subsequent RET call would just use the address you just pushed to JMP back in a sense. Is there a specific reason that you don't want to use CALL or is it not available for you? For

问题 Why do the Silerlight-generated WCF proxy class(es) offer only async calls? There are cases where I don't really need the async pattern (for example in a BackgroundWorker) EDIT : Sometimes I need to process the results of two WCF calls. It would have been much simpler if I could have waited (the business of the app allows that) for both calls to end and then process.. but noooo.... async! :P 回答1: There's actually a technical reason you can't do sync calls, at least from the 'main' browser

问题 v is an object of Vertex , and Scale is a method for a pointer to Vertex . Then why is v.Scale(10) not wrong, given that v isn't a pointer to a Vertex object? Thanks. package main import ( "fmt" "math" ) type Vertex struct { X, Y float64 } func (v Vertex) Abs() float64 { return math.Sqrt(v.X*v.X + v.Y*v.Y) } func (v *Vertex) Scale(f float64) { v.X = v.X * f v.Y = v.Y * f } func main() { v := Vertex{3, 4} v.Scale(10) fmt.Println(v.Abs()) } 回答1: Spec: Calls: A method call x.m() is valid if the

问题 If from inside a bat file you called another batch file but still had a few remaining operations to complete, how can you make sure that the call to first bat file will after completion or error, will return to the file that called it in the first instance? Example: CD:\MyFolder\MyFiles Mybatfile.bat Copy afile toHere or CD:\MyFolder\MyFiles CALL Mybatfile.bat COPY afile toHere What is the difference between using CALL or START or none of them at all? Would this have any impact on whether it

问题 In the following call-by-value example, I cannot understand why this code is not changing the value of the 5 to a 6. Line 11 calls the function changeValue which has the value 6, so I would have thought 6 should be output, however 5 is still output? #include <iostream> using namespace std; void changeValue(int value); int main() { int value = 5; changeValue(value); cout << "The value is : " << value << "." << endl; return 0; } void changeValue(int value) { value = 6; } // This doesn't change

问题 I want to call a custom function I wrote within my Google Apps Script. When I execute a getJSON I suppose it'll automatically run my doGet(e). My Javascript: $.getJSON(https://script.google.com/macros/s/[ID]/exec, function(data){ //code here }); Is there a possible way to call one of my custom functions for example My Google Apps Script: function getNumberOfFans(e){ //code here } Do I have to add some kind of extra function parameter to my URL? 回答1: In either a "stand alone" or bound Apps

问题 Is there any way to detect global AJAX calls (particularly responses) on a web page with generic JavaScript (not with frameworks)? I've already reviewed the question "JavaScript detect an AJAX event", here on StackOverflow, and tried patching in the accepted answer's code into my application but it didn't work. I've never done anything with AJAX before either so, I don't know enough to modify it to work. I don't need anything fancy, I just need to detect all (specific, actually, but I'd have

问题 This question already has an answer here : subprocess.call using string vs using list (1 answer) Closed 5 years ago . I am trying to get python's subprocess.call method to accept some args commands through a list (consisting of a sequence of strings) as advised in the python documentation. To explore this behavior before putting it into my actual script, I opened up IPython, ran some commands involving different combinations of shell settings and args commands and got the following behavior:

问题 Now I have two classes allmethods.cs and caller.cs . I have some methods in class allmethods.cs . I want to write code in caller.cs in order to call a certain method in the allmethods class. Example on code: public class allmethods public static void Method1() { // Method1 } public static void Method2() { // Method2 } class caller { public static void Main(string[] args) { // I want to write a code here to call Method2 for example from allmethods Class } } How can I achieve that? 回答1: Because
