   how to get the synchronization between the system mouse and the texture mouse?
  how to get the synchronization between the system mouse and the texture mouse.when i got the position of the mouse on the sreen,but i find it was not the exact position ,so i want to know how to make them synchronization.   
  Which operating system do you use? Which programming language do you use? And, what on earth is a texture mouse??? Do you mean you emulate a mouse pointer by a texture mapped face? You'll need to describe the problem in more detail ...   ;  the operating system i use is winXP ,and i use C++ language,yes i emulate a mouse pointer by a texture mapped face.   ;  So you want to use the OS-mousespeed for your own mouse.   ;  yes,and i use direct3D 9.0,i find that when i use getcursor funtion,the position is not synchronization with the mouse which paint by texture.so i want to make them synchronization and how??   ;  You don't need to synchonise with anything [smile].Mice work in terms of relative coordinates, that is, the driver only reports delta values, which are translated by the API into absolute coordinates. In your message loop you only need to get the delta values and transform them into absolute coordinates yourself.That way you are free to define mouse-sensitivity and custom cursor boundaries without any API calls.HTH,Pat
