Properties

DebugLogFilePath
Function ComDebugLogFilePath Returns String
Procedure Set ComDebugLogFilePath String value

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.

More Information and Examples
top
LastBinaryResult
Function ComLastBinaryResult Returns Variant

This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to True. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.

top
LastErrorHtml
Function ComLastErrorHtml Returns String

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
Function ComLastErrorText Returns String

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
Function ComLastErrorXml Returns String

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
Function ComLastMethodSuccess Returns Boolean
Procedure Set ComLastMethodSuccess Boolean value

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
LastStringResult
Function ComLastStringResult Returns String

In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.

top
LastStringResultLen
Function ComLastStringResultLen Returns Integer

The length, in characters, of the string contained in the LastStringResult property.

top
MessageCount
Function ComMessageCount Returns Integer

The number of emails in this bundle.

top
VerboseLogging
Function ComVerboseLogging Returns Boolean
Procedure Set ComVerboseLogging Boolean value

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
Function ComVersion Returns String

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

Methods

AddEmail
Function ComAddEmail cComChilkatEmail email Returns Boolean

Adds an email object to the bundle.

Returns True for success, False for failure.

top
AddMimeBytes
Function ComAddMimeBytes Variant mimeBytesOrText Returns Boolean

Adds an email to the bundle object. The mimeBytesOrText is the email in MIME format.

Returns True for success, False for failure.

top
FindByHeader
Function ComFindByHeader String headerFieldName String headerFieldValue Returns cComChilkatEmail

Returns the first email having a header field matching the headerFieldName and headerFieldValue exactly (case sensitive). If no matching email is found, returns null.

Returns null on failure

top
GetEmail
Function ComGetEmail Integer index Returns cComChilkatEmail

Returns the Nth Email in the bundle. The email returned is a copy of the email in the bundle. Updating the email object returned by GetEmail has no effect on the email within the bundle. To update/replace the email in the bundle, your program should call GetEmail to get a copy, make modifications, call RemoveEmailByIndex to remove the email (passing the same index used in the call to GetEmail), and then call AddEmail to insert the new/modified email into the bundle.

IMPORTANT: This method does NOT communicate with any mail server to download the email. It simply returns the Nth email object that exists within it's in-memory collection of email objects.

Returns null on failure

top
GetUidls
Function ComGetUidls Returns cComCkStringArray

Returns a StringArray object containing UIDLs for all Email objects in the bundle. UIDLs are only valid for emails retrieved from POP3 servers. An email on a POP3 server has a "UIDL", an email on IMAP servers has a "UID". If the email was retrieved from an IMAP server, the UID will be accessible via the "ckx-imap-uid" header field.

Returns null on failure

top
GetXml
Function ComGetXml Returns String

Converts the email bundle to an XML document in memory. Returns the XML document as a string.

Returns null on failure

top
LoadTaskResult
Function ComLoadTaskResult cComChilkatTask task Returns Boolean
Introduced in version 9.5.0.52

Loads the email bundle from a completed asynchronous task.

Returns True for success, False for failure.

top
LoadXml
Function ComLoadXml String filename Returns Boolean

Loads an email bundle from an XML file.

Returns True for success, False for failure.

top
LoadXmlString
Function ComLoadXmlString String xmlStr Returns Boolean

Loads an email bundle from an XML string.

Returns True for success, False for failure.

top
RemoveEmail
Function ComRemoveEmail cComChilkatEmail email Returns Boolean

Removes an email from the bundle. This does not remove the email from the mail server.

Returns True for success, False for failure.

top
RemoveEmailByIndex
Function ComRemoveEmailByIndex Integer index Returns Boolean

Removes the Nth email in a bundle. (Indexing begins at 0.)

Returns True for success, False for failure.

top
SaveXml
Function ComSaveXml String filename Returns Boolean

Converts each email to XML and persists the bundle to an XML file. The email bundle can later be re-instantiated by calling MailMan.LoadXmlFile

Returns True for success, False for failure.

top
SortByDate
Procedure ComSortByDate Boolean ascending

Sorts emails in the bundle by date.

top
SortByRecipient
Procedure ComSortByRecipient Boolean ascending

Sorts emails in the bundle by recipient.

top
SortBySender
Procedure ComSortBySender Boolean ascending

Sorts emails in the bundle by sender.

top
SortBySubject
Procedure ComSortBySubject Boolean ascending
