A Couple of Winmm API Calls
There are 2 API Calls to the Winnmm API. One Detects if a Sound Card is installed. The other Plays an .AVI. You need to have Windows Media Player installed.
Original Author: Charles Davis
Assumptions
This code is very simple and pretty self explanatory.
Side Effects
As far as I know there are none.
API Declarations
'For SoundCard Function
Private Declare Function waveOutGetNumDevs Lib "winmm.dll" () As Long
'To Play Avi
Private Declare Function mciSendString Lib "winmm.dll" Alias _
"mciSendStringA" (ByVal lpstrCommand As String, _
ByVal lpstrReturnString As Any, ByVal uReturnLength As Long, _
ByVal hwndCallback As Long) As Long
Code
Public Function SoundCard() As Boolean
Dim lng As Long
lng = waveOutGetNumDevs()
If lng > 0 Then
SoundCard = True
Exit Function
Else
SoundCard = False
Exit Function
End If
End Function
Public Sub PlayAvi()
Dim strAviPath As String
Dim strCmdStr As String
Dim lngReturnVal As Long
strAviPath = "C:winntclock.avi"
strCmdStr = "play " & strAviPath & " fullscreen "
lngReturnVal = mciSendString(strCmdStr, 0&, 0, 0&)
End Sub
