VB4/16 BIT/hWndDisplay/AVI

I am using the hWndDisplay property of a multimedia control to display AVIs in a picture box.  The AVI to be displayed is selected by the user from a list.  I would like to automatically adjust the size of the picture box to fit the AVI, but I don't know what aspect/property of the AVI to address.  Is there a way to do this?

Have you tried to change the PictureBox to AutoSize?

Send mci command to the Avi to resize to coordinates you will give it (in pixels).
I've also paste how do I place the Avi on a windows since  don't know how you did it. (You would be nice to tell me.)
Here is the code:

===========================
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
    Public Const MCI_WINDOW = &H841
        Public Const MCI_OVLY_WINDOW_ENABLE_STRETCH = &H100000
        Public Const MCI_OVLY_WINDOW_HWND = &H10000
        Type MCI_OVLY_WINDOW_PARMS
            dwCallback As Long
            hwnd As Long
            nCmdShow As Long
            lpstrText As String
        End Type
    Public Const MCI_PUT = &H842
        Public Const MCI_OVLY_PUT_DESTINATION = &H40000
        Public Const MCI_OVLY_RECT = &H10000
        Type MCI_OVLY_RECT_PARMS
            dwCallback As Long
            rc As RECT
        End Type



Dim API As Integer
Dim AviWindows As MCI_OVLY_WINDOW_PARMS
Dim AviPutRect As MCI_OVLY_RECT_PARMS
        'Put in Window
            AviWindows.hwnd = frmMain.hwnd
            AviWindows.dwCallback = frmMain.hwnd
            API = mciSendCommand(frmMain.MMCtrl.DeviceID, MCI_WINDOW, MCI_OVLY_WINDOW_ENABLE_STRETCH + MCI_OVLY_WINDOW_HWND, AviWindows)
        'Scale to full Windows
           
            AviPutRect.rc.Bottom = frmMain.ScaleHeight
            AviPutRect.rc.Top = 0
            AviPutRect.rc.Left = 0
            AviPutRect.rc.Right = frmMain.ScaleWidth
            AviPutRect.dwCallback = frmMain.hwnd
            API = mciSendCommand(frmMain.MMCtrl.DeviceID, MCI_PUT, MCI_OVLY_PUT_DESTINATION + MCI_OVLY_RECT, AviPutRect)

I placed the AVI into the picture box with the following code:
MMControl1.hWndDisplay = Picture1.hWnd
MMControl1.command = "open"
MMControl1.command = "play"

P.S.  I tried setting the picture box autosize property to True, but apparantly that only works for graphics and not AVIs.
