Receive the read-only list of IMAP mailboxes populated by
Use the mailbox count and index-based methods to retrieve each mailbox
name in the returned collection.
Inspect IMAP flags associated with each mailbox, including standard and
server-specific attributes.
Determine whether a mailbox can be selected and opened for message
access.
Check whether a mailbox has child mailboxes or whether children may be
created beneath it.
Detect whether a mailbox is marked or unmarked according to the
attributes returned by the IMAP server.

Inspect IMAP mailbox names and attributes returned by Chilkat.Imap.
Chilkat.Mailboxes is a read-only result collection populated by
Chilkat.Imap.MbxList. Applications inspect the returned mailbox
names and attributes but do not directly add, remove, or modify entries. The
class provides indexed access to mailbox flags, selectable status, marked
status, whether child mailboxes exist, and whether child mailboxes may be
created.

Chilkat.Imap.MbxList to populate a
Mailboxes object, loop from 0 to
Count - 1, retrieve each mailbox name, and inspect its flags or
selectable status. Mailbox names are exposed as normal Unicode text; Chilkat
automatically handles modified UTF-7 or IMAP UTF-8 at the protocol level.
Create/Dispose
HCkMailboxes instance = CkMailboxes_Create(); // ... CkMailboxes_Dispose(instance);
Creates an instance of the HCkMailboxes object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.
Objects created by calling CkMailboxes_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkMailboxes_Dispose.
Properties
Count
Returns the number of mailboxes in this collection. An empty collection has a count of 0.
Mailboxes is a read-only result container populated by Imap.MbxList. Applications inspect the returned entries but do not directly add, remove, or modify mailboxes in this object.
DebugLogFilePath
void CkMailboxes_putDebugLogFilePath(HCkMailboxes cHandle, const char *newVal);
const char *CkMailboxes_debugLogFilePath(HCkMailboxes cHandle);
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.
LastErrorHtml
const char *CkMailboxes_lastErrorHtml(HCkMailboxes cHandle);
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.
topLastErrorText
const char *CkMailboxes_lastErrorText(HCkMailboxes cHandle);
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.
LastErrorXml
const char *CkMailboxes_lastErrorXml(HCkMailboxes cHandle);
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.
topLastMethodSuccess
void CkMailboxes_putLastMethodSuccess(HCkMailboxes cHandle, 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. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.
Utf8
void CkMailboxes_putUtf8(HCkMailboxes cHandle, 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.
VerboseLogging
void CkMailboxes_putVerboseLogging(HCkMailboxes cHandle, 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.
Version
const char *CkMailboxes_version(HCkMailboxes cHandle);
Methods
GetFlags
const char *CkMailboxes_getFlags(HCkMailboxes cHandle, int index);
Returns a comma-separated list of flags for the mailbox at the zero-based index specified by index.
For example:
\HasNoChildren,\Important
To inspect the flags individually, use GetNumFlags and GetNthFlag.
Returns TRUE for success, FALSE for failure.
GetMailboxIndex
Returns the zero-based index of the mailbox whose name matches mbxName.
Pass mbxName as a normal Unicode mailbox name. Chilkat automatically handles the protocol-level modified UTF-7 or IMAP UTF-8 representation; the application should not encode the mailbox name manually.
The returned index can be used with methods such as GetName, GetFlags, and IsSelectable.
GetName
const char *CkMailboxes_getName(HCkMailboxes cHandle, int index);
Returns the name of the mailbox at the zero-based index specified by index.
The name is returned as normal Unicode text. Chilkat automatically decodes modified UTF-7 or IMAP UTF-8 mailbox names received from the server and automatically performs the corresponding encoding when the name is passed to an Imap method.
The returned name can therefore be passed directly to methods that select, examine, create, rename, delete, copy to, or otherwise operate on a mailbox. Do not manually encode or decode the mailbox name.
Returns TRUE for success, FALSE for failure.
GetNthFlag
const char *CkMailboxes_getNthFlag(HCkMailboxes cHandle, int index, int flagIndex);
Returns one flag from a mailbox in the collection.
indexis the zero-based mailbox index.flagIndexis the zero-based flag index within that mailbox.
Call GetNumFlags to determine the number of flags available for the mailbox.
Returns TRUE for success, FALSE for failure.
GetNumFlags
Returns the number of flags associated with the mailbox at the zero-based index specified by index.
Returns -1 if index is outside the valid mailbox-index range. Use GetNthFlag to retrieve the individual flags.
HasFlag
Returns TRUE if the mailbox at the zero-based index specified by index contains the flag named by flagName.
Flag-name comparison is case-insensitive. Include the leading backslash when checking an IMAP system flag or mailbox attribute, for example \Marked, \Noselect, or \HasChildren.
HasInferiors
Returns TRUE if the mailbox at the zero-based index specified by index either has child mailboxes or permits child mailboxes to be created beneath it.
\HasNoChildren means that no child mailboxes currently exist. It does not mean that children cannot be created. The IMAP \Noinferiors attribute means that child mailboxes cannot be created.
IsMarked
Returns TRUE if the mailbox at the zero-based index specified by index has the IMAP \Marked attribute.
\Marked is a server-provided hint that the mailbox may contain messages added since it was last selected. It is advisory information returned by the mailbox-listing operation.
IsSelectable
Returns TRUE if the mailbox at the zero-based index specified by index can be selected or examined for message access.
A mailbox having the IMAP \Noselect attribute is not selectable, even though it may appear in the mailbox hierarchy and may contain selectable child mailboxes.
LoadTaskResult
Loads this object from a completed asynchronous task whose result is a Mailboxes collection.
task must reference a completed Task returned by the asynchronous form of an operation that produces mailbox-listing results.
Returns TRUE for success, FALSE for failure.
