PidTagAttachSize Canonical Property
Applies to: Office 2010 | Outlook 2010 | Visual Studio
Contains the sum, in bytes, of the sizes of all properties on an attachment.
Associated properties: |
PR_ATTACH_SIZE |
Identifier: |
0x0E20 |
Data type: |
PT_LONG |
Area: |
Message attachment |
Remarks
It is recommended that attachment subobjects expose the PR_ATTACH_SIZE property. The sum contained in PR_ATTACH_SIZE includes the size of the PR_ATTACH_DATA_BIN (PidTagAttachDataBinary) or PR_ATTACH_DATA_OBJ (PidTagAttachDataObject) property. Accordingly, PR_ATTACH_SIZE is usually larger than the contents of the attachment alone.
This property can be used to check the approximate size of the attachment before performing a remote transfer by modem and to display progress indicators when saving the attachment to disk. It is particularly useful with attached OLE objects.
