afspille et video klip i en form
			hvordan afspiller jeg et videoklip i en form. Den skal ikke åbne en player i et nyt vindue, og man skal i formen ikke kunne se fx. knapperne som er på win meiaplayer komponenten?

			du kan ogsaa bruge en picturebox og nogle api kald
blandt andet
Private Declare Function mciSendCommand Lib "winmm.dll" Alias "mciSendCommandA" (ByVal wDeviceID As Long, ByVal uMessage As Long, ByVal dwParam1 As Long, ByRef dwParam2 As Any) As Long
du kan jo soege paa google efter mci api der er en masse eks. derude.

			det her kan du ikke gøre med WindowsMediaPlayer :
i et modul:
Option Explicit
Const WS_CHILD = &H40000000
Private Declare Function mciSendString Lib "winmm.dll" Alias _
    "mciSendStringA" (ByVal lpstrCommand As String, _
    ByVal lpstrReturnString As String, ByVal uReturnLength As Long, _

    ByVal lpstrBuffer As String, ByVal uLength As Long) As Long
Private Declare Function GetShortPathName Lib "kernel32.dll" Alias _
    "GetShortPathNameA" (ByVal lpszLongPath As String, _
    ByVal lpszShortPath As String, ByVal cchBuffer As Long) As Long
Public deviceIsOpen As Boolean
Public Function PlayVideo(FileName As String, ByVal VideoBox As PictureBox)
    Dim RetVal As Long
    Dim CommandString As String
    Dim ShortFileName As String * 260
    ' Retrieve short file name format
    RetVal = GetShortPathName(FileName, ShortFileName, Len(ShortFileName))
    FileName = Left$(ShortFileName, RetVal)
    
    ' Open the device
    CommandString = "Open " & FileName & " type AVIVideo alias AVIFile parent " & _
    CStr(VideoBox.hWnd) & " style " & CStr(WS_CHILD)
    RetVal = mciSendString(CommandString, vbNullString, 0, 0&)
    If RetVal Then GoTo error
        ' remember that the device is now open
        deviceIsOpen = True
        ' Resize the movie to PictureBox size
        CommandString = "put AVIFile window at 0 0 " & CStr _
        (VideoBox.ScaleWidth / Screen.TwipsPerPixelX) & " " & _
        CStr(VideoBox.ScaleHeight / Screen.TwipsPerPixelY)
        RetVal = mciSendString(CommandString, vbNullString, 0, 0&)
    If RetVal <> 0 Then GoTo error
   
    ' Play the file
    CommandString = "Play AVIFile" 'wait"
    RetVal = mciSendString(CommandString, vbNullString, 0, 0&)
    If RetVal <> 0 Then GoTo error
    
'    ' Close the device
'    CommandString = "Close AVIFile"
'    RetVal = mciSendString(CommandString, vbNullString, 0, 0&)
'    If RetVal <> 0 Then GoTo error
    Exit Function
    
error:
    ' An error occurred.
    ' Get the error description
    Dim ErrorString As String
    ErrorString = Space$(256)
    mciGetErrorString RetVal, ErrorString, Len(ErrorString)
    ErrorString = Left$(ErrorString, InStr(ErrorString, vbNullChar) - 1)
    ' close the device if necessary
    If deviceIsOpen Then
        CommandString = "Close AVIFile"
        mciSendString CommandString, vbNullString, 0, 0&
    End If
    ' raise a custom error, with the proper description
    Err.Raise 999, , ErrorString
    
End Function
Public Function CloseVideo()
mciSendString "Close AVIFile", vbNullString, 0, 0&
        
End Function
Public Function StopPlaying()
mciSendString "Stop AVIFile", vbNullString, 0, 0&
        
End Function
