If you don`t use a Playlist then you will need to use the AxWindowsMediaPlayer1.PlayStateChange event to detect when the media ends so you can start the next video.

Being you can`t start the next video from within the PlayStateChange event you will need to use a Timer with a small delay like 200 milliseconds and in the Tick event you start the next video.

I take it you want a loop effect so in this example i check if it is the last video that ended and if it is then i start the first video again.

You can test the code in a new Form project with 1 Button and 1 AxWindowsMediaPlayer added to the form. You will also need a folder in the Debug folder named "Videos" with your video files in it.
