Example

Here is example or playlist initialization and adding a file to it:

Dim myPlaylist As New MPlaylistClass()
myPlaylist.PreviewWindowSet("", panelPreview.Handle.ToInt32())
myPlaylist.PreviewEnable("", 1, 1)
myPlaylist.ObjectStart(New Object())
'Insert clip at the end of playlist
Dim nIndex As Integer = -1
Dim pFile As MItem
Dim strPath As String = "d:\clips\SampleClip1.wmv"
myPlaylist.PlaylistAdd(Nothing, strPath, "", nIndex, pFile)
myPlaylist.FilePlayStart()
MPlaylistClass myPlaylist = new MPlaylistClass();
myPlaylist.PreviewWindowSet("", panelPreview.Handle.ToInt32()); 
myPlaylist.PreviewEnable("", 1, 1);
myPlaylist.ObjectStart(new object());
//Insert clip at the end of playlist
int nIndex = -1;
MItem pFile;
string strPath = @"d:\clips\SampleClip1.wmv";
myPlaylist.PlaylistAdd(null, strPath, "", ref nIndex, out pFile);
myPlaylist.FilePlayStart();
var
nIndex: integer;
pItem: MItem;
myPlaylist: MPlaylist;
myPreview: IMPreview;
myEvents: TEvents;
myFile:IMFile;
myObject:IMObject;
cookie: LONG_PTR;
begin
myPlaylist:= CreateComObject(CLASS_MPlaylist) as MPlaylist;
myPreview:= myPlaylist as IMPreview;
myObject:= myPlaylist as IMObject;
myEvents:=TEvents.Create();
myObject.ObjectCallbackSet(myEvents, cookie);
myFile:=myPlaylist as IMFile;
myPreview.PreviewWindowSet('', panelPreview.Handle);
myPreview.PreviewEnable('', 1, 1);
nIndex:=-1;
myPlaylist.PlaylistAdd(nil, 'c:\myFile.avi', '', nIndex, pItem);
