问题 I'm using Visual Studios. I wrote a method in a form1.cs file in a partial class private void TestMethod1() { } I want to call this method in form2.designer.cs, in the same partial class. I tried this: TestMethod1(); but I got the error method not found. this is the form.cs namespace classA { public partial class A : B {.... private void TestMethod1() { } } } this is the form.designer.cs namespace classA { partial class A { private void InitializaCOmponent() { ..... } (where I call my

问题 If we call a function directly in R, lazy evaluation takes place, so that the function arguments are not evaluated until they are encountered in the function body. An effect of this is that using match.call() at the beginning of a function, say a model fitter like lm , captures the call with unevaluated function arguments. Thus, the call to the function can be retrieved with promises instead of evaluated arguments by executing the model fitting function. The disadvantage of this is that the

问题 I have php function by multi parameter. I want to call this function with setting only last argument. Simple way is setting other argument empty . But it isn't good. Is any way to call this function with setting last argument and without setting other argument? See this example: function MyFunction($A, $B, $C, $D, $E, $F) { //// Do something } //// Simple way MyFunction("", "", "", "", "", "Value"); //// My example MyFunction(argument6: "Value") 回答1: My suggestion is use array instead of

问题 I recently asked how to test in RSpec if a block was called and the answers to that question seem to work in a simple case. The problem is when the initialization with the block is more complex. Then it is done in before and reused by a number of different tests in the context, among them the one testing if the block was evaluated. See the example: context "the node definition using block of code" do before do @n=node do # this block should be called end # some more complex setup concerning

问题 this is how i call a function from menu.lua at main.lua local menu = require("menu") menu.drawMenu() but how i gonna call a function from main.lua at menu.lua ? is it possible ? or set a listener or something like that 回答1: If you are simply looking to provide actions for the menu, would it not be better to use a set of call back functions (as used when building GUI elements) to be triggered when menu items are clicked?

问题 Let's say I have a private function addUser() in function.php that takes $username as an input variable and does some stuff: function addUser($username) { //do some stuff } Now I want to call this function and pass the value $username, if possible with PHP CLI. I guess that won't work from outside function.php since it's private, but how could I do this then? 回答1: php -r 'include("/absolute/path/to/function.php"); addUser("some user");' This should work. Because you are basically executing

问题 How (actual with which instuments like ReSharper) in VS10 developer can find "unsafe" method invokes - i.e. invokes, which unattainable by call stack in no one safe block (try-catch) ? class A { public static vois f() { try { ... B.DoSome(); // safe call, exceptions handled } catch(Exception e) { ... } } public static void f2() { ... //no try-catch block B.DoSome(); // possible unhandled exception } } class B { public static void DoSome() { ... //no try-catch block, possible to raise

问题 A previous post shows how to use quote() to create an unevaluated call to a function where the arguments are also unevaluated: foo <-function(arg1,arg2){ value <- arg1 + arg2 } foocall <- call("foo",arg1=quote(x),arg2=quote(y)) foocall # foo(arg1 = x, arg2 = y) How can I keep this quality but allow the specification of arg1 to change. E.g, I have two named objects n and m in my environment and sometimes I would like to pass over one and sometimes I would like to pass over the other. ## Named
