变量的适当位置 [英] proper place for a variable
问题描述
您好，
我需要在所有应用程序特定表单和类中使用一个特定值
我的应用程序。什么是适当的地方？目前我使用带有公共常量的
模块，这似乎是一个方便的地方。传递它
作为参数似乎并不是非常有效。你有什么建议？
谢谢
Frank
Hello,
I need one specific value in all the applicationspecific forms and classes
of my application. What is the proper place to put it? At the moment I use a
module with a public constant and that seems to be a handy place. Passing it
as a parameter doesn''t seem to be very efficient. What do you suggest?
Thanks
Frank

Even though allowing global variables is a decidedly non-OO feature brought
forward from previous VB versions, I would be very tempted to do exactly as
you are now doing. I would not agree if it were a variable instead of a
named constant, but I see no harm in a global named constant.

记住，模块是一个''密封''类自动导入，所有
成员和属性都是''共享''。
就个人而言，我避免使用模块和显式使用类，这个
避免了模块周围的所有混淆。

Remember, a module is a ''Sealed'' Class which in imported automatically, all
members and properties are ''Shared''.
Personally, I avoid Modules and perfer to explicitly use Classes, this
avoids all the confusion surrounding Modules.

你应该在一个类中声明你的公共常量，让GLOBALS
公共类GLOBALS
Public Const PI As Double = 3.142
结束班
Dim a As Double = GLOBALS.PI

You should declare your public constants in a class, lets GLOBALS
Public Class GLOBALS
Public Const PI As Double = 3.142
End Class
Dim a As Double = GLOBALS.PI
