Properties

Day
Function ComDay Returns Integer
Procedure Set ComDay Integer value

The day of the month. The valid values for this member are 1 through 31.

top
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

Hour
Function ComHour Returns Integer
Procedure Set ComHour Integer value

The hour. The valid values for this member are 0 through 23.

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
Minute
Function ComMinute Returns Integer
Procedure Set ComMinute Integer value

The minute. The valid values for this member are 0 through 59.

top
Month
Function ComMonth Returns Integer
Procedure Set ComMonth Integer value

The month. The valid values for this member are 1 through 12 where 1 = January and 12 = December.

top
Second
Function ComSecond Returns Integer
Procedure Set ComSecond Integer value

The second. The valid values for this member are 0 through 59.

top
StructTmMonth
Function ComStructTmMonth Returns Integer
Procedure Set ComStructTmMonth Integer value

The month. The valid values for this member are 0 through 11 where 0 = January and 11 = December.

top
StructTmYear
Function ComStructTmYear Returns Integer
Procedure Set ComStructTmYear Integer value

The year represented as the number of years since 1900.

top
Utc
Function ComUtc Returns Boolean
Procedure Set ComUtc Boolean value

True if this is a UTC time, otherwise False if this is a local time.

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"

More Information and Examples
top
Year
Function ComYear Returns Integer
Procedure Set ComYear Integer value

The year, such as 2012.

Methods

DeSerialize
Procedure ComDeSerialize String serializedDtObj

Loads the date/time with a string having the format as produced by the Serialize method, which is a string of SPACE separated integers containing (in this order) year, month, day, hour, minutes, seconds, and a UTC flag having the value of 1/0.

top
Serialize
Function ComSerialize Returns String

Serializes the date/time to a us-ascii string that can be imported at a later time via the DeSerialize method. The format of the string returned by this method is not intended to match any published standard. It is formatted to a string with SPACE separated integers containing (in this order) year, month, day, hour, minutes, seconds, and a UTC flag having the value of 1/0.

Returns null on failure
