"I can't found a way to disable controls and make then invisible... but i got the same effect by dragging an image box just over the Window Media Controls, so user can't operate and see them..."
Answer to this, since i can't add a comment:
To hide Windows Media Controls:
Click on properties on the player > Controls Layout > None
(This will hide the controls)
To make it invisible:
Put a timer and put enabled = true on properties > right click on the timer and Show Code
Here put in:
If you want to close the player:
axWindowsMediaPlayer1.close();
if you want to hide the player, but still play in the background:
axWindowsMediaPlayer1.Hide();
Click properties on the timer again and choose a interval
This will make Windows Media Player close/hide after a time (interval)
