[求助]救命啊，要死人啦，引用DLL为什么报错？一切语法正确啊！ Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 　　 Private AUTO Declare Function PlaySound lib "winmm.dll" (ByVal lpszSoundName As String, ByVal hModule As Integer, ByVal dwFlags As Integer) As Integer Const SND_FILENAME As Integer = &H20000 Const SND_ALIAS As Integer = &H10000 Const SND_SYNC As Integer = &H0 Dim mstrfileName As String = "c:\test.wav" PlaySound(mstrfileName, 0, SND_FILENAME) End Sub C:\OziExplorer\ozitest\Form1.vb(70): AUTO关键字作为标识符无效。 C:\OziExplorer\ozitest\Form1.vb(75): 名称“PlaySound”未声明。 图片可以点击放大看现场：

你是不是应该把  Private AUTO Declare Function PlaySound lib "winmm.dll" (ByVal lpszSoundName As String, ByVal hModule As Integer, ByVal dwFlags As Integer) As Integer
写在Button1_Click的上边啊，试一下
