访问另一个进程中的控件对象 [英] Access a control object in another process

问题描述

首先，我不知道这个问题包含在这个论坛部分。
如果没有，抱歉。
...例如，这是两个过程（winform风格和每个winform都有一个按钮）。我称这两个winform为'A'和'B'。
我想从B访问A的按钮，如下所示。
（假设我知道A按钮的窗口句柄。

- B侧码 -
按钮A_button = new Button（）; //创建一个表示A按钮的按钮对象。
A_button = ....（A的句柄）//输入按钮的窗口是A_button对象的一个​​窗口。

然后从B侧自由控制A_button。
A_button.Click（）;
...

是否可能？
如果那时，我想知道如何在另一个过程中将句柄信息输入到同一类型的对象。
从这里工作，我想从B winform远程控制一个winform。
请告诉我。

Firstly, I do not know this my question is included in this forum section.
If not, sorry.
...
For example, threre are two process(winform style and each winform has a button).
I called that two winform as 'A' and 'B'.
I want to access A's button from B as like below.
(Assume I know the window handle of A's button.

-- B side code --
Button A_button = new Button(); // create a button object that meaning A's button.
A_button = ....(handle of A's) // input A button's window hanle to A_button object.

// and then control freely A_button from B side.
A_button.Click();
...

Is it possible?
If then, I want to know how to input the handle information to the same type object in another process.
from this work, I want to remote control A winform from B winform.
Please advise to me.

推荐答案

在Form2中创建一个公共方法并从Form1中调用它

Create a public method in Form2 and call it from Form1

'Code for Form 1

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim frm As New Form2
        frm.Show()
        frm.MyButtonClick()
    End Sub
End Class




'Code for Form 2
Public Class Form2

    Public Sub MyButtonClick()
        Button1.PerformClick()
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        MsgBox("Hello from Form 2")
    End Sub
End Class

您也可以在Form2 public中创建Button1_Click，然后使用以下代码

You can also create Button1_Click in Form2 public and then use following code

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim frm As New Form2
        frm.Show()
        frm.Button1_Click(Me, e)
    End Sub
