MessageSet Lianja Reference Documentation

MessageSet

Current Version: 9.5.0.75

Represents a collection of email message sequence numbers or UIDs on an IMAP server.

Object Creation

loObject = createobject("CkMessageSet")

Properties

Count
Count As Numeric (read-only)

The number of message UIDs (or sequence numbers) in this message set.

top
HasUids
HasUids As Boolean

If .T. then the message set contains UIDs, otherwise it contains sequence numbers.

top
LastMethodSuccess
LastMethodSuccess As Boolean

Indicate whether the last method call succeeded or failed. A value of .T. indicates success, a value of .F. indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = .T. and failure = .F..
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to .T.. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

1:5,8:10

1,3,4,5,8,9,10

1,3:5,8:10

top
GetId
GetId(index As Numeric) As Numeric

Returns the message ID of the Nth message in the set. (indexing begins at 0). Returns -1 if the index is out of range.

top
InsertId
InsertId(id As Numeric)

Inserts a message ID into the set. If the ID already exists, a duplicate is not inserted.

top
LoadTaskResult

Introduced in version 9.5.0.52

Loads the message set from a completed asynchronous task.

Returns .T. for success, .F. for failure.

top
RemoveId
RemoveId(id As Numeric)

Removes a message ID from the set.

top
ToCommaSeparatedStr
ToCommaSeparatedStr() As Character

Returns a string of comma-separated message IDs. (This is the non-compact string format.)

Returns .F. on failure

top
ToCompactString
ToCompactString() As Character
