New pc causing “namespace of type specified in the imports doesn't contain any public member” in VB.NET

由 删除回忆录丶 提交于 2019-12-08 19:58:57
问题 I just got a new PC (Win 7) with VS 2010 (same version as my old PC). I got a VB.NET solution from source control that contains two projects. One of the projects builds fine. The other project flags every non-MS Imports statement with: Namespace or type specified in the Imports &1 doesn't contain any public members or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. The ironic

public method returns private class instance in Java?

问题 I have a method that returns an instance of a private class and I need access to its methods from a different package for unit testing. These classes live in the same file. It goes like this: file: A.java public class A{ B b; public B getB(){ return b; } public setB(B b){ this->b = b; } } class B{ C c; public C getC(){ return c; } public setC(C c){ this->c = c; } } class C{ public int getInt(){ return 1; } } So... Basically the question is: are any of the methods in B or C reachable somehow?

Is there a way to make a value accessible only to the parent of a nested class VB.NET?

问题 In general, according to the OOP paradigm, my understanding of encapsulation basically says: If a member is private, it can only be accessed by the class. If a member is protected, it can only be accessed by the base class and any derived classes. If a member is public, it can be accessed by anyone. If I have a nested class, can I declare a property to be accessible only to that class and the parent class it's nested within? For example: Public Class ContainerClass Public Class NestedClass

Why fragment class should be public?

问题 I found some threads that explain why a Fragment class should be static (not non-static inner ) like this. But can't understand the reason for this error message: This fragment class should be public (...) I use Android Studio 3.1.2 and this is a part of my codes: public class MainActivity extends android.support.v7.app.AppCompatActivity { // ... } class DefaultFragment extends android.support.v4.app.Fragment { // ... } The fragment is supposed to be used only in MainActivity . EDIT: There is

问题 I have a class that has A LOT of public variables and I need to be able to get a list of them. Here's an example of my class: public class FeatList: MonoBehaviour { public static Feat Acrobatic = new Feat("Acrobatic", false, ""); public static Feat AgileManeuvers = new Feat("Agile Maneuvers", false, "" ); void Start(){}} Except there are about 100 more variables. Is there any possible way to get all these member variables in one manageable array? Or have I screwed myself over? 回答1: If by

Confusion on when to use private vs protected fields

由 牧云@^-^@ 提交于 2019-12-07 07:35:12
问题 I have seen users in SO saying that protected fields are bad, because it can introduce problems as the code grows. Please refer to the following code. public class Car { private String modelName; private int yearReleased; //getters and setters } If the Car class is extended by a class named ToyotaCar public class ToyotaCar extends Car{ // Toyota specific stuff } I want my ToyotaCar object to have a modelName and yearReleased fields. And that is why I decided to extend from Car class. But

Access Modifiers - what's the purpose?

由 廉价感情. 提交于 2019-12-07 05:00:47
问题 I'm relatively new to programming in general and I was wondering if anyone could help me understand the purpose of access modifiers? I understand the fact that they set different levels of access for classes and variables etc. but why would you want to limit what has access to these? What is the point in not allowing access for different things? why not just allow access for everything? Sorry if this is a stupid question! 回答1: There are thousands of reasons, but I'll quote a few from here and

Besides accessibility, what else access-specifiers effects?

由 烈酒焚心 提交于 2019-12-07 01:32:37
问题 Besides the normal explenation of being visible or not to derived classes, is their any other difference? If you make it more visible, is it taking more or less memory, does it slow thing down or...? 回答1: Apart from the accessibility of members outside or to the derived classes, access specifiers might affect the object layout. Quoting from my other answer: Usually, memory address for data members increases in the order they're defined in the class . But this order may be disrupted at any

Visual C# 2010 Express: Specify default access modifier for new classes?

由 陌路散爱 提交于 2019-12-06 22:11:27
问题 Whenever I create new classes using Visual Studio 2010 Express C# it creates them with no access modifier. 9 times out of 10 I want my new classes to be public. How can I have Visual Studio create empty class templates with the "public" modifier by default? 回答1: The trick is to create a new item template named Class. Then when you do Add > New Class, your template will be selected by default rather than the built-in Class template. (I am not sure if this behaviour is guaranteed but it Works
