// Progress.cpp
//
// Progress dialog to Start, Stop, Pause, Resume and Restart a service.
//
// IMPLEMENTATION
// Since an operation (ie, Start, Stop, Pause, Resume or Restart) may take
// a while, a thread is created to do the actual work while a dialog
// is displayed to the user.
// 0. Allocate CServiceControlProgress object on the heap
// 1. Create a thread in suspended mode.
// 2. Create the dialog.
// 3. Dialog creates a timer to update the progress bar.
// 4. Dialog resumes the thread.
// 5. Thread opens the service and perform the requested operation(s).
// 6. Dialog updates UI using its timer.
// 7. Thread updates dialog UI as well.
// 8. Thread waits until the dialog is dismissed. Dialog can be
// dismissed for any of the following event:
// a) Operation completed successfully.
// b) User hit cancel button.
// c) An unexpected error occured.
// d) Operation times out.
// 9 Thread deletes CServiceControlProgress object.
//
// HISTORY
// 03-Oct-95 t-danmo Creation of (sysmgmt\dsui\services\progress.cxx)
// 30-Sep-96 t-danmo Renamed and adapted to MMC.
// 14-May-97 t-danm Fully implemented the "Restart" feature.
