如何检测按键事件？

Question

当我单击此表单并按下键盘上的某个按钮时，

MessageBox不会显示。

Private Sub MainForm_KeyPress(sender As Object, e As KeyPressEventArgs) Handles Me.KeyPress
    MessageBox.Show(e.KeyChar.ToString)
End Sub

Answer 1

将表单的KeyPreview属性设置为true

Answer 2

将Me.KeyPress更改为MyBase.KeyPress ...这将有效

Private Sub MainForm_KeyPress(sender As Object, e As KeyPressEventArgs) Handles MyBase.KeyPress
    MessageBox.Show(e.KeyChar.ToString)
End Sub
