从用户控件中的文本框声明文本作为整个应用程序的变量 [英] declarion text from a textbox in a usercontrol as a variable for the whole app

问题描述

我的总体目标是为远程计算机获取不同的计算机信息.

我有几个用户控件都拉不同的信息.一个用户控件获取信息(机器名)，而我需要其他用户控件来查看它.

我的设置方法是，我有一个文本框和一个按钮，然后单击按钮，我希望应用程序提取机器信息.

我已经读过有关全局变量的信息，但是我是编程的新手.
我试过了:

My overall goal is pulling different machine information for remote machines.

I have several user controls all pull different information. One user controls gets the information (machine name) and I need the others user controls to see it.

The way I have it set up is I have a text box and a button and on button click I would like the application to pull the machine information.

I have read about global variables, but I am new to programming.
I have tried:

Dim comphost as string
comphost = machinename.text

我认为我走了正确的道路，但我需要帮助.

I think I am on the right path, but I need help.

推荐答案

这完全取决于您要对变量执行的操作. UserControls将如何处理此信息?

回答您的评论.您应该在主表单中创建一个公共属性，如下所示:-

It all depends on what you want to do with the variable. What will the UserControls do with this information ?

In answer to your comment. You should create a public property in your main form, something like this:-

Public Property CompHost() As String
Get
    return compHost
End Get
Set(ByVal Value As String)
    compHost = Value
End Set
End Property

然后在用户控件中创建一个构造函数，该构造函数将字符串作为参数，并在打开它时传递此属性，如下所示:-

公共

then in your user control you create a constructor that takes a string as a parameter and pass in this property when you open it, something like this:-

Public

Class myUserControl

    Public Sub myUserControl(compHost As String)
        'do something with compHost
    End Sub

End Class

也许这会给你一个更好的主意.祝你好运！

Maybe this will give you a better idea. Good luck!
