To move the mouse cursor, use the SetCursorPos function.

POINT pt;
::GetCursorPos(&pt);

pt.x += 3;
pt.y += 7;

::SetCursorPos(pt.x, pt.y);

I'm trying to move the cursor, using postmessage function, and sending WM_MOUSEMOVE signal to windows.

If you want to set the x,y coords in the LPARAM then you can use the MAKELPARAM macro.

MAKELPARAM(low,high)  so for you this would be MAKELPARAM(x,y)

NOTE: x,y must be in screen coords

pWnd->PostMessage(WM_MOUSEMOVE, 0, MAKELPARAM(x, y));

The x and y are coordinate relative to the upper-left corner of the client area of pWnd.
