What is wrong with this code

[Bonio Lopez <bo...@gmx.de>]

Dear All,
I am very new with log4Net. Since use 1.2.9 version no log file is written.
I beleave that I missconfigured something, since the configuration is
changed. 
Below is the full configuration. Can somebody please comment, did I forgot
something? How can I debug this?
Thank you in advance,
boni

 
Private Shared m_FileAppender As log4net.Appender.FileAppender
...
m_FileAppender = New log4net.Appender.FileAppender
m_FileAppender.Layout = New log4net.Layout.PatternLayout("%timestamp
[%thread] %level %logger %ndc - %message%newline")
m_FileAppender.File = path_to_log + "\" + m_logger_file_name
m_FileAppender.LockingModel = m_LockingModel
log4net.Util.LogLog.InternalDebugging = True
log4net.Config.BasicConfigurator.Configure(m_FileAppender)

LogManager.GetLogger("Mylogger").Error("Hello")
