MessageSet ActiveX Reference Documentation

MessageSet

Current Version: 11.0.0

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

Object Creation

Note:
For versions of Chilkat < 10.0.0, use "Chilkat_9_5_0.MessageSet" instead of "Chilkat.MessageSet"
For a specific major version, use "Chilkat.MessageSet.<major_version>", such as "Chilkat.MessageSet.10" for Chilkat v10.*.*
See Chilkat ActiveX Object Creation

(ASP)
set obj = Server.CreateObject("Chilkat.MessageSet")

(AutoIt)
$obj = ObjCreate("Chilkat.MessageSet")

(Visual Basic 6.0)
Dim obj As New MessageSet

(VBScript)
set obj = CreateObject("Chilkat.MessageSet")

(VBA, such as Excel)
Dim obj As New MessageSet
See How to Use ActiveX in Excel

(Delphi)
obj := TMessageSet.Create(Self);

(FoxPro)
loObject = CreateObject('Chilkat.MessageSet')

(PowerBuilder)
lole_object = create oleobject
li_rc = lole_object.ConnectToNewObject("Chilkat.MessageSet")

(SQL Server)
EXEC @hr = sp_OACreate 'Chilkat.MessageSet', @obj OUT

(Javascript)
var obj = new ActiveXObject("Chilkat.MessageSet");

Properties

Count

Count As Long (read-only)

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

DebugLogFilePath

DebugLogFilePath As String

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.

HasUids

HasUids As Long

If 1 then the message set contains UIDs, otherwise it contains sequence numbers.

top

LastBinaryResult

LastBinaryResult As Variant (read-only)

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 1. 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

LastErrorHtml As String (read-only)

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

LastErrorText As String (read-only)

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

LastErrorXml As String (read-only)

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

LastMethodSuccess As Long

Indicates the success or failure of the most recent method call: 1 means success, 0 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

LastStringResult As String (read-only)

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

LastStringResultLen As Long (read-only)

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

top

VerboseLogging

VerboseLogging As Long

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
