Log Lianja Reference Documentation

Log

Current Version: 10.1.2

Handy logging class exposing much of the functionality used internally by Chilkat for LastErrorText, LastErrorXml, and LastErrorHtml.

Object Creation

loObject = createobject("CkLog")

Properties

DebugLogFilePath
DebugLogFilePath As Character

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
LastErrorHtml
LastErrorHtml As Character (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 Character (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 Character (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 Boolean

Indicates the success or failure of the most recent method call: .T. means success, .F. 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
VerboseLogging
VerboseLogging As Boolean

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

Methods

Clear
Clear(initialTag As Character)

Introduced in version 9.5.0.44

Enters a new context labelled with the given tag. Must be paired with a matching call to LeaveContext.

More Information and Examples
top
LeaveContext
LeaveContext()
Introduced in version 9.5.0.44

Leaves the current context. A context that is entered and exited without any logging within the context is automatically removed from the log. (To say it another way: Empty contexts are automaticallly removed from the log upon leaving the context.)

top
LogData
LogData(tag As Character, message As Character)
Introduced in version 9.5.0.44

Adds a tagged message to the log (i.e. a name/value pair).

top
LogDataMax
LogDataMax(tag As Character, message As Character, maxNumChars As Numeric)
Introduced in version 9.5.0.44

Logs a string, but only up to the 1st maxNumChars characters of the string.

top
LogDateTime
LogDateTime(tag As Character, gmt As Boolean)
Introduced in version 9.5.0.44

Logs the current date/time in RFC822 format. If gmt is .T., then the GMT/UTC time is logged. Otherwise it is the local time.

top

Introduced in version 9.5.0.44

Logs an informational message within the current context.

top
LogInt
LogInt(tag As Character, value As Numeric)
Introduced in version 9.5.0.44

Logs an integer.

top
LogInt64
LogInt64(tag As Character, value As Numeric)
Introduced in version 9.5.0.44

Logs a 64-bit integer.

top
LogTimestamp
