how to execute an command during shut down or restart

[ask_you]

i have developed and application where i handle the WM_ENDSESSION ON_MESSAGE(WM_ENDSESSION,OnMyEndSession) LRESULT CMyDlg::OnMyEndSession(WPARAM wParam, LPARAM lParam) { ShellExecute ( NULL, "open", "C:\\abc.exe, NULL, NULL, SW_HIDE ) ; } But the executable(abc.exe) is not executed.

What does OnMyEndSession() return? What is the value of wParam? You should probably handle the WM_QUERYENDSESSION message instead. This message is sent first, and if all applications respond with TRUE, Windows is going to shut down/restart. It wouldn't make sense to start up another application at this point since it would have not had a chance to respond to the WM_QUERYENDSESSION message.
