代碼是沒有錯的，但是其中關鍵是聲音文件資源定義字串必須使用根命名空間，不能用程序集名稱；還有就是聲音文件必須選屬性為嵌入資源。
My.Computer.Audio.Play(My.Resources.xxxmusic1xxx, AudioPlayMode.Background)
首先要確定播放的視頻格式是什么格式，如果是windows media player支持的格式，直接使用該控件就行了，如果是單個視頻的話，比如命名為myPlayer,則：
myPlayer.url="視頻文件完整路徑"
首先將swf文件添加進資源，方法：
假設資源文件是workergame.swf（你按照自己的改），將其釋放到臨時文件，供AxShockwaveFlash控件播放，完整代碼：
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim size As Long = My.Resources.workergame.Length - 1
Dim buffer(CInt(size)) As Byte
buffer = My.Resources.workergame.ToArray
Dim fn As String = IO.Path.Combine(My.Computer.FileSystem.SpecialDirectories.Temp, "workergame.swf")
Dim fs As New IO.FileStream(fn, IO.FileMode.Create)
fs.Write(buffer, 0, buffer.Length)
fs.Close()
AxShockwaveFlash1.Movie = fn
End Sub
