全局变量 [英] Global variables

问题描述

如何在表单回发后创建保持其值

的全局变量（例如，当点击按钮时单击
等等）非常感谢你。

解决方案

你能更具体一点吗？如果你在谈论全局

变量，那么Application对象可以存储可在整个应用程序中访问的变量

。

例如，我想要从我的潜艇和

函数中读取和写入四到五个变量

。我遇到的问题是，每次点击一个按钮（asp：按钮）时，

这些

可变的松散值。当我尝试只有DIM的

变量时，当Page.IsPostBack = False时，函数

最初看不到变量而我收到了

恭维错误。谢谢

How do i create global variables that keep their values
after the form is postback, (i.e. when a button is
clicked, etc.) Thank you very much.

解决方案

Can you be more specific? If you are talking about global
variables, then the Application object can store variables
that are accessible within the whole application.

.

For instance, i would like to have four or five variables
than can be read and written to from my subs and
functions. The problem that i am having is that
everytime a button (asp:button) is clicked these
varaibles loose there values. When i try to only DIM the
variables, when Page.IsPostBack = False, the functions
can''t initially see the variables and I recieve
compliation errors. Thank you
