DODownloadPropertyEx enumeration

Important

The DODownloadPropertyEx enumeration is deprecated. Instead, use the DODownloadProperty enumeration with IDODownload::GetProperty and IDODownload::SetProperty.

The DODownloadPropertyEx enumeration specifies the ID of extended properties for the Delivery Optimization download operation. This enumeration is used by the IDODownloadInternal interface, and a VARIANT value is used to get and set the property value.

  DODownloadPropertyEx_IntegrityCheckMandatory, 
  DODownloadPropertyEx_TotalSizeBytes, 
  DODownloadPropertyEx_TempLocalFileUsage 
} DODownloadPropertyEx;
