The scope and accessibility of js variables are discussed in every language. variables are an element used to store information. For example, the following function:
The Code is as follows:
Function Student (name, age, from){This. name = name;This. age = age;This. from = from;This. ToString = function (){Return "my information is name:" + this. name + ", age:" + this. age + ", from:" + this. from;}}
The Student class has three variables: name, age

Every language has the concept of variables, which are an element used to store information. For example, the following function:1 function Student (name, age, from)2 {3 this. name = name;4 this. age = age;5 this. from = from;6 this. ToString = function ()7 {8 return "my information is name:" + this. name + ", age:" + this. age + ", from:" + this. from;9}10}The Stud

Public:
Double test (double dvalue) {return dvalue * 13 ;};

If your answer is 169, you are wrong!Because the above functions cannot be compiled at all! The compiler will give you an error that cannot access private members.Surprised? Can the compiler not find the public member function Double test (double dvalue
The Reasons and methods for my Google search are as follows:Http://blog.csdn.net/SkyIsland/archive/2006/04/15/664716.aspx
Cause: one of them is that the access level of the returned parameter is lower than the access level of the function,What should I do?That is, when defining a method for returning parameters, if the access level of the returned parameters is lower than the access level of the method, this error will occur. From Oo, this is understandable, if the returned parameters cannot be

base class A in B). Because the members in base class A are already private in Class B, Class C does not inherit any members of Class A and cannot be converted to a base class. (4) In the case of protected inheritance, a member of a subsequent derived class (a derived class C of Class B) can be converted to a base class type (Class A) (a member function, by virtue of its own member function) (because protected inherits, the natural derived class can access the base class member, A member of a b
(); }}The output is as follows: The overridden method of the parent class can be called inside a subclass, but the overridden method of the parent class cannot be called externally.This is due to encapsulation considerations, to avoid external programs calling the overridden method of the parent class directly, and avoiding the subclass's new validation logic for the overridden method. Also for encapsulation purposes, the subclass can invoke the overridden method of the parent class, such as

When the project is upgraded to VS2010 or 2012 (and the NET version is also upgraded to 4.0), the following error message is displayed:
The "XXX" type violates the inherited security rules. The derived type must match the Security accessibility of the base type or be less accessible than the base type.

Environment: ArcGIS Server 9.3
The brand-new ArcGIS lelesdk in ArcGIS Server 9.3 has extended the charm of ArcGIS Server to the Windows Mobile platform, filling in the gaps of ArcGIS enterprise-level mobile platform applications; the ArcGIS API forFlex/JS that will be launched later will make heavy makeup in the WebGIS field and bring a good user experience.

The so-called keyboard accessibility options are defined by Microsoft as "adjusting computer settings for visual, listening, and operational capabilities." This is very important for users.

You can use the Reg property to make validation more powerful, and you can use several regular expressions preset in $.panzer.reg to determine the format of mailboxes:
maintenance because programmers can quickly understand these modules and can debug them without harming other modules. Although the encapsulation itself, both internal and external, will not bring better performance, but it makes effective performance tuning possible. Once a system has been completed and analyzed to see which modules affect the performance of the system, these modules can be further optimized without affecting the correctness of the other modules. Encapsulation can improve soft
