// 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.
