I have ran into a "small" brick wall. Hoping that I can find a couple
of log4net guru's here. My situation.
In trying to make my logging as configurable as possible in my
application, I have been tinkering with trying to set the boolean values
for appendToFile and staticLogFileName as dynamic values. These have a
default value (currently stored in the My.Settings metadata). My
problem is that when I go to configure the values at runtime I get this
error in my stack trace:

The way that I am configuring the values is by trying to use the code
displayed here:
'In Main
Private Shared Log As ILog
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles MyBase.Load
'[...]
primeLogging()
configLog4Net()
Log =
LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().Dec
laringType)
Log.Info("This is the start of the application.")
End Sub
Private Sub primeLogging()
If Not My.Settings.LogPath = "" Then
_LogPath = My.Settings.LogPath
Else
_LogPath = My.Application.Info.DirectoryPath &
"\Logs\"
End If
'[...]
_MaxRollBacks = My.Settings.MaxRollBacks
_MaxFileSize = My.Settings.MaxFileSize
_isAppendToFile = My.Settings.isAppendToFile
_isStaticLogFile = My.Settings.isStaticLogFile
End Sub
Private Sub configLog4Net()
log4net.GlobalContext.Properties("LogPath") = _LogPath
log4net.GlobalContext.Properties("LogName") = _LogName
log4net.GlobalContext.Properties("RollStyle") =
_tempRollStyle
log4net.GlobalContext.Properties("MaxRollBacks") =
_MaxRollBacks
log4net.GlobalContext.Properties("MaxFileSize") =
_MaxFileSize
log4net.GlobalContext.Properties("isAppendToFile") =
_isAppendToFile
log4net.GlobalContext.Properties("isStaticLogFile") =
_isStaticLogFile
'My attempts to cast as a boolean (did not work)
'log4net.Util.OptionConverter.ToBoolean(log4net.GlobalContext.Properties
("isAppendToFile"), _isAppendToFile)
'log4net.Util.OptionConverter.ToBoolean(log4net.GlobalContext.Properties
("isStaticLogFile"), _isStaticLogFile)
End Sub

All of my other appenders work (ConsoleLog, EventLog and ErrLogFile
(when I remove the appendToFile paramter).
Please any assistance would be most appreciated.
