DonManfred Expert Licensed User Longtime User Mar 1, 2014 #3 Code: Copy Sub Button3_Click camEx.Release End Sub Code: Copy Sub Button3_Click camEx.StopPreview End Sub If you want preview again later then you should use StopPreview and later StartPreview... If you want to leave to activity then i would say Release is more what you want... If you leave due to calling a new activity and later when you come back from this activity your activity would be resumed. Due to the release you must do a new initialization i think... Upvote 0
