Mouse movement

[Farabi]

Im making a mouse function, the task is I want to know if the value of X and Y are positive or negative and after it determined it the cursor reseted to the center of application, Its work, but when I set the cursor to the window center it keep give me a positive value. I am missing something?

Of course it will give only positive values.
What do you expect :} you even prevent mouse cursor from moving outside client area (if I'm right .. with ClipCursor)
You'll get negative values only when you'll use SetCapture AND u r holding mouse button while moving AND mouse cursor is outside active window area

No I mean, a less value than the center of the application, I called that a negativ value or a jmp less.

Nevermind, I found the mistake.
