问题 i'm sort of a n00b to VB and was wondering how to make a variable available across multiple Subs. It's just a test app to get familiar with VB.

Main_Menu.Show() Me.Close() End If End Sub Private Sub ABCs_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase

问题 I'm building a HTML-app with the AngularJS framework. I have some legacy JavaScript actions that needs to access a function within the Angular-object, and I can't get it to work. This is the Angular-object (function I need to access is the $scope.info() ): function content($scope) { $scope.info = function (id) { console.log('Got a call from '+id); $scope.text = "Hello, "+id; }; } I have attempted to access it through angular.element('content').scope().info('me') , but with no result (console

问题 I was wondering how to access a global function fn in ruby from a class which also defined a method fn . I have made a workaround by aliasing the function like so: def fn end class Bar alias global_fn fn def fn # how to access the global fn here without the alias global_fn end end I'm looking for something along the lines of c++'s :: to access global scope but I can't seem to locate any information about it. I guess I don't know specifically what I'm looking for. 回答1: At the top-level a def

问题 This might be a really dumb question but I'm learning .NET, so I'm quite clueless... Let's say I have two files default.aspx and the associated default.aspx.cs. default.aspx.cs: protected void Page_Load(object sender, EventArgs e) { var myObject = new MyObject(); } Is there a way that in the default.aspx I could do something like: <%= myObject.SomePropertyOfThisObject%> ... or something similar, without having to use databinders or something complicated like this? And if there's no way around

问题 This question already has answers here : How to write a transaction to cover Moving a file and Inserting record in database? (4 answers) Closed 2 years ago . I've been using TransactionScope to work with the database and it feels nice. What I'm looking for is the following: using(var scope=new TransactionScope()) { // Do something with a few files... scope.Complete(); } but obviously this doesn't work -- if there are 20 files, and an exception occurs on the 9th file, all previous 8 remain

问题 What's the difference between: class Person(name: String, age: Int) { def say = "My name is " + name + ", age " + age } and class Person(val name: String, val age: Int) { def say = "My name is " + name + ", age " + age } Can I declare parameters as var s, and change their values later? For instance, class Person(var name: String, var age: Int) { age = happyBirthday(5) def happyBirthday(n: Int) { println("happy " + n + " birthday") n } } 回答1: For the first part the answer is scope: scala>

问题 Here's a very simplified version of my project. I have a class file: class MyClass{ public var myNumberStoredInClass:Number; // constructor function MyClass(myNumber:Number){ this.myNumberStoredInClass = myNumber; }; // some method function DoStuffMethod(){ trace(this.myNumberStoredInClass); }; }; // end class I have a normal .as file from which I can access this.myNumberStoredInClass with no problems with MyClass.myNumberStoredInClass until I call setTimeout for a method in the class:
