Dim log As New Chilkat.Log

' Initialize the log object with an initial context tag:
log.Clear("myLog")

' Add some information..
log.LogInfo("Hello, I'm here...")

' Open a sub-context
log.EnterContext("abc")

' New information is now logged within the "abc" context.
log.LogInfo("This is inside the abc context")
log.LogError("File not found.")

' Perhaps open a new context...
log.EnterContext("fileInfo")
log.LogData("filename","something.txt")
log.LogData("path","/somedir/xyz")
log.LeaveContext()

' Close the "abc" context.
log.LeaveContext()


' Examine the content of the log:
Debug.WriteLine(log.LastErrorText)

' This is the output:

' myLog:
'   Hello, I'm here...
'   abc:
'     This is inside the abc context
'     File not found.
'     fileInfo:
'       filename: something.txt
'       path: /somedir/xyz
'     --fileInfo
'   --abc
' --myLog
