Thanks for suggestion, but HxW it self is too small to become full screen , so I have to set a size of screen (1024*768+) , this way I get almost full screens but controls (tracker + play stop buttons ) won't go. By increasing height to 780 approx controls goes out of screen. But still it's not perfect full screen.
Got the solution :- if you see I was using classid of WMP 6.4, this code works well on win2k systems with wmp6.4 as native default.
But in xp by default it is 7+, and with sp2/3 it's wmp9.
From wmp7 onwords classid of wmp changed . after changing the classid I was able to use parameters like full screen and ui.mode=none.
This did the trick and now it is playing in full screen without any issues.
Will post the full code if some one needs it in future.
