问题描述

Public Class Form1

    Public Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ComboBox1.Items.Add("thankyou")
        ComboBox1.Items.Add("myproject")


        If ComboBox1.Text = "thankyou" Then


    Public AxWindowsMediaPlayer1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AxWindowsMediaPlayer1.enter
            Dim startSoundPlayer As System.Media.SoundPlayer
            startSoundPlayer = New System.Media.SoundPlayer("C:\Users\Natasha\Music\migente.wav")


            InitializeComponent()
            AxWindowsMediaPlayer1.URL = "C:\Users\Natasha\Music\migente.wav"

            startSoundPlayer.Play()


            MessageBox.Show("Congratulations!")
            Close()

        ElseIf ComboBox1.Text = "myproject" Then
              Public AxWindowsMediaPlayer1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AxWindowsMediaPlayer1.Enter
            Dim startSoundPlayer As System.Media.SoundPlayer
            startSoundPlayer = New System.Media.SoundPlayer("C:\Users\Natasha\Music\pooja.wav")


            InitializeComponent()
            AxWindowsMediaPlayer1.URL = "C:\Users\Natasha\Music\pooja.wav"

            startSoundPlayer.Play()


            MessageBox.Show("Congratulations!")
            Close()

        End If
    End Sub
End Class

What I have tried:

i have tried changing handles,but i dnt know how to change it,im only getting an error on the> ByVal .

推荐答案

也许你应该在开始声明之前结束你的 Form1_Load 方法 AxWindowsMediaPlayer1_Enter 处理程序方法？



你不能坚持

Perhaps you should end your Form1_Load method before you start declaring the AxWindowsMediaPlayer1_Enter handler method?

You can't just stick

Public AxWindowsMediaPlayer1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AxWindowsMediaPlayer1.Enter

在另一个方法中随机出现，根本不起作用。

randomly inside another method, that won't work at all.
