单击主窗体上的按钮时如何更改辅助窗体上按钮的功能

Question

我正在制作一个程序，我希望链接 form2 上的按钮以根据我在 form1 中单击的按钮播放不同的声音。

如何做到这一点？

Answer 1

Form1.vb

Public beepButtonClicked As Boolean = False
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    beepButtonClicked = True
End Sub

Form2.vb

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    If Form1.beepButtonClicked = True Then
        MessageBox.Show("Button clicked after beepButton was clicked")
    End If
End Sub

或者如果你想要多种声音：

Form1.vb

Public beepButtonClicked As String = "sounds/sound1.wav"
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    beepButtonClicked = "sounds/sound2.wav"
End Sub

Form2.vb

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    axWindowsMediaPlayer1.URL = beepButtonClicked
End Sub
