CkMessageSetW Unicode C++ Reference Documentation

CkMessageSetW

Current Version: 10.1.0
Requires Chilkat Bundle License

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

Object Creation

// Local variable on the stack
CkMessageSetW obj;

// Dynamically allocate/delete
CkMessageSetW *pObj = new CkMessageSetW();
// ...
delete pObj;

Properties

Count
int get_Count(void);

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

top
HasUids
bool get_HasUids(void);
void put_HasUids(bool newVal);

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

top
LastMethodSuccess
bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false 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 = true and failure = false.
  • 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 true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

Methods

ContainsId
bool ContainsId(unsigned long msgId);

Returns true if the msgId is contained in the message set.

top
FromCompactString
bool FromCompactString(const wchar_t *str);

Loads the message set from a compact-string representation. Here are some examples:

Non-Compact String

Compact String

1,2,3,4,5

1:5

1,2,3,4,5,8,9,10

1:5,8:10

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

1,3:5,8:10

top
GetId
unsigned long GetId(int index);

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

top
InsertId
void InsertId(unsigned long id);

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

top
LoadTaskResult
bool LoadTaskResult(CkTaskW &task);
Introduced in version 9.5.0.52

Loads the message set from a completed asynchronous task.

Returns true for success, false for failure.

top
RemoveId
void RemoveId(unsigned long id);

Removes a message ID from the set.

top
ToCommaSeparatedStr
bool ToCommaSeparatedStr(CkString &outStr);
const wchar_t *toCommaSeparatedStr(void);

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

Returns true for success, false for failure.

top
ToCompactString
bool ToCompactString(CkString &outStr);
const wchar_t *toCompactString(void);

Returns the set of message IDs represented as a compact string. Here are some examples:

Non-Compact String

Compact String

1,2,3,4,5

1:5

1,2,3,4,5,8,9,10

1:5,8:10

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

1,3:5,8:10

Returns true for success, false for failure.
