Inversarea directiei de mers a mouseului

[SlicK]

Un mic programel

#include <windows.h>

int main()
{
  POINT NewPoint,OldPoint; // coordonatele mouseului
  RECT rc;
  GetWindowRect(GetDesktopWindow(),&rc); // limitele ecranului
  GetCursorPos(&OldPoint); // coordonata mouseului la pornirea prog
  while(1)
  {
    Sleep(10);
    GetCursorPos(&NewPoint); // coordonata curenta
// daca noua pozitie se incadreaza in limitele ecranului o setam
    if(OldPoint.x*2-NewPoint.x>rc.left && OldPoint.x*2-NewPoint.x<rc.right)  NewPoint.x=OldPoint.x*2-NewPoint.x;
    if(OldPoint.y*2-NewPoint.y>rc.top  && OldPoint.y*2-NewPoint.x<rc.bottom) NewPoint.y=OldPoint.y*2-NewPoint.y;
    SetCursorPos(NewPoint.x,NewPoint.y); // mutam mouseul in noua pozitie
    OldPoint=NewPoint;
  }
}
