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 LongPrivate Sub Command1_Click () Timer1.Enabled = TrueTimer1.Interval = 100Call McISendstring ("Close All", 0, 0, 0) 'First closes all MCI devices, avoid playing multiple music files, overlapping Call McISendstring ("Open" "C: /Winnt/Media/ringin.wav" , 0, 0, 0) 'Open the MCI device Call McIndString ("Play" "C: /Winnt/Media/ringin.wav", 0, 0, 0) play MCI device end subsprivate sub timer1_timer ()

Dim Buffer AS String * 128Dim POS AS Integer McIndstring "Status C: /Winnt/Media/ringin.wav Mode", Buffer, 128, 0 &

POS = INSTR (Buffer, Chr (0)) IF Left (Buffer, POS - 1) = "Stopped" THEN CALL MCISENDSTRING ("Close All", 0, 0, 0) Call McIndString ("Open" "C: / Winnt / Media / Ringin.wav ", 0, 0, 0) Call McIndstring (" Play " " C: /Winnt/Media/ringin.wav ", 0, 0, 0) End IFEND SUB
