I try to use all 4 options in my 'program'. I can change video position with SendMessage(hwndFW,WM_COMMAND,904,0) same as JumpForward(large),or SendMessage(hwndFW,WM_COMMAND,893,0) same as 'Go to',and last option is using webinterface of MPC-HC,and it works fine 'localhost:13579/command.html?wm_command=-1&position=00:06:55' in browser. I can set position when i start MPC with CreateProcessA with argument '/startpos 00:05:01'. I try to make my own control to MPC HC64.
