//  ConnectionScheduleDialog ()
//
//  Invoke a dialog to set/modify a schedule, for example
//      -- the logon hours for a particular user
//      -- the schedule for a connection
//
//  RETURNS
//  Return S_OK if the user clicked on the OK button.
//  Return S_FALSE if the user clicked on the Cancel button.
//  Return E_OUTOFMEMORY if there is not enough memory.
/// Return E_UNEXPECTED if an expected error occured (eg: bad parameter)
//
//  INTERFACE NOTES
//  Each bit in the array represents one hour.  As a result, the
//  expected length of the array should be (24 / 8) * 7 = 21 bytes.
//  For convenience, the first day of the week is Sunday and
//  the last day is Saturday.
//  Consequently, the first bit of the array represents the schedule
//  for Sunday during period 12 AM to 1 AM.
//  - If *pprgbData is NULL, then the routine will allocate
//    an array of 21 bytes using LocalAlloc ().  The caller
//    is responsible of releasing the memory using LocalFree ().
//  - If *pprgbData is not NULL, the routine re-use the array as its
//    output parameter.
//

//  17-Jul-97   t-danm      Creation.
