MessageSet C++ Reference Documentation

CkMessageSet

Current Version: 11.0.0
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
CkMessageSet obj;

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

Properties

Count
int get_Count(void);

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

top
DebugLogFilePath
void get_DebugLogFilePath(CkString &str);
const char *debugLogFilePath(void);
void put_DebugLogFilePath(const char *ansiOrUtf8Str);

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

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
LastErrorHtml
void get_LastErrorHtml(CkString &str);
const char *lastErrorHtml(void);

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorText
void get_LastErrorText(CkString &str);
const char *lastErrorText(void);

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorXml
void get_LastErrorXml(CkString &str);
const char *lastErrorXml(void);

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

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

Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

top
Utf8
bool get_Utf8(void);
void put_Utf8(bool newVal);

When set to true, all const char * arguments and return values are interpreted as UTF-8 strings. When set to false, they are interpreted as ANSI strings.

In Chilkat v11.0.0 and later, the default value is true. Before v11.0.0, it was false.

top
VerboseLogging
bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
void get_Version(CkString &str);
const char *version(void);

Version of the component/library, such as "10.1.0"

Methods

ContainsId
bool ContainsId(unsigned long msgId);

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

top
FromCompactString
bool FromCompactString(const char *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(CkTask &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 char *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 char *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.
