ya i have seen that message..but rotation angle will be dynamically i want to mention..how should i calculate that rotation angle..when mouse moves on form..

well clearly he is saying that from the mouse click you can get the point where it was clicked ... then you can track the movement from that point to figure out a direction and hence the angle no? i think...

try storing the initial mouse click position then use that point, along with the center point of the object and the current mouse pos and use pythagaros (not sure on spelling) thery to calculate angle base on three point, oh you will also have to calculate the distance from points

My opinion is... If someone has already posted an answer, dont post the SAME answer
