windows - Hooking mouse input and moving cursor -

i'm setting global mouse hook:

hmousehook = setwindowshookex(wh_mouse_ll, llmouseproc, getmodulehandle(0), 0); 

and hooking mouse move messages , moves mouse cursor.

lresult callback llmouseproc(int ncode, wparam wparam, lparam lparam) {     lpmsllhookstruct lpmh = reinterpret_cast<lpmsllhookstruct>(lparam);     uint             nmsg = static_cast<uint>(wparam);     point            ptscreen = { 0 };      if (ncode >= 0)     {         ptscreen = lpmh->pt;         if (wm_mousemove == nmsg)         {             // ptscreen coordinates receiving in physical units (pixels)             // convert them logical             point logpos = { ptscreen.x, ptscreen.y };             convertphysicaltological(&logpos);              // move mouse cursor new position             // setcursotpos() requires coordinates in logical units             setcursorpos(logpos.x, logpos.y);              // don't want propagate message             return 1l;         }     }     return 0l; } 

everything works if scale factor 1.0... ok how works. move mouse physical coordinate [29,94], let say, our scale factor 1.5, logical coordinates [19,62]. call

setcursorpos(19, 62); 

it triggers sending wm_mousemove , somewhere internally converts our logical coordinates physical 19 * 1.5 = 28, 62 * 1.5 = 93, our new input coordinates [28,93] instead of [29,94]. we're repeating everything, converting [28,93] logical [18, 62] , call

setcursorpos(18, 62); 

and on...

so, know calling setcursorpos() llmouseproc isn't correct , i'm trying find solution - there proper way it?

p.s.> clipcursor() doesn't because calls setcursorpos()

thank you!
