grabber = New Capture()

回答by IvanH
There should be something like
应该有类似的东西
Private Sub button1_Click(sender As System.Object, e As System.EventArgs) Handles button1.Click
or
或者
AddHandler button1.Click, AddressOf button1_Click
I suppose its vb.net and winforms. With VB6 or WPF is a solution little bit different.
我想它的 vb.net 和 winforms。使用 VB6 或 WPF 是一个有点不同的解决方案。

- Go to the Forms designer.
- Select the Button.
- In the Properties Pane, bottom right by default, click the "Lightning Bolt" Icon.
- Find the "Click" entry.
- Click the small dropdown arrow to the right and select "button1_click".
- 转到表单设计器。
- 选择按钮。
- 在属性窗格中，默认右下角，单击“闪电”图标。
- 找到“点击”条目。
- 单击右侧的小下拉箭头并选择“button1_click”。
The handler should now be again associated with your buttons click event.
处理程序现在应该再次与您的按钮单击事件相关联。

Change the declaration like this:
像这样更改声明：
Private Sub button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
