Playing AVI through MCI [resolved]

[JasonC]

Ok, here is the problem...
I am playing with playing an AVI file through the MCI, and ran into a problem when it comes to the video.

The video has a background that's transparent, which keeps appearing at Magenta on my form.

Is there way to show it actually transparent?

Here is my code....
On a form, add:

3 command buttons
1 picture box
1 timer

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

Dim sAlias As String
Dim rReturn As Long


Private Sub Command1_Click()
Dim mssg As String * 255

    sTheFile = "c:\filecopy.avi"
    sAlias = Right$(sTheFile, 3) & Minute(Now)
    nReturn = mciSendString("Open " & sTheFile & " ALIAS " & sAlias & " TYPE AviVideo wait parent " & Picture1.hWnd & " Style " & &H40000000, "", 0, 0)

    nReturn = mciSendString("set " & sAlias & " time format ms", 0&, 0, 0)

    nReturn = mciSendString("status " & sAlias & " length", mssg, 255, 0)
    Timer1.Interval = mssg + 500
    Me.Caption = mssg

End Sub

Private Sub Command2_Click()
    nReturn = mciSendString("play " & sAlias, 0&, 0, 0)
    Timer1.Enabled = True
End Sub

Private Sub Command3_Click()
    nReturn = mciSendString("stop " & sAlias, 0&, 0, 0)
    nReturn = mciSendString("close " & sAlias, 0&, 0, 0)
    Timer1.Enabled = False
End Sub

Private Sub Timer1_Timer()
    nReturn = mciSendString("play " & sAlias & " from 0", 0&, 0, 0)
End Sub

The video is the FILECOPY.AVI from the Microsoft Visual Studio\Common\Graphics\Videos folder.

Any help would be greatly appreciated....
