直接用API函数mciSendString就行了:

Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" _
(ByVal lpstrCommand As String, ByVal lpstrReturnString As String, _
ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long

Private Sub Command1_Click()
'开始录音
Dim iRet As Long
iRet = mciSendString("open new type waveaudio alias MyRecord", 0&, 0, 0)
iRet = mciSendString("set MyRecord bitspersample 16 samplespersec 16384", 0&, 0, 0)
iRet = mciSendString("record MyRecord overwrite", 0&, 0, 0)
End Sub

Private Sub Command2_Click()
'保存录音
Dim iRet As Long
iRet = mciSendString("save MyRecord c:\1.wav", 0&, 0, 0)
iRet = mciSendString("close MyRecord", 0&, 0, 0)
End Sub

追问

这是用c++语言写的吗？Private Sub Command1_Click()........End Sub是什么？
