This is a part of code that i try to make a shutdown with timer. I have 2 combo box, one is for shutdown/restart selection, one is for time selection. What should I code to make user press the apply button to process the selected process with the timer in that two combo box? And what is the code for shutdown and restart? system("shutdown") is unusable.

Please forgive my broken english

you may send CB_GETCURSEL to the combo box to check the selected item index
and you may use ExitWindowsEx to shutdown/ restart
