Subject RE: Using AdoNetAppender

I may have to try that.  Currently it just fails with an "Oject
reference not set to an instance of an object."

Thanks,

James.

Have you already gotten AdoNetAppender to work from a app.config /
web.config first?  If not, I'd suggest getting that to work first.  You
may learn something in that process and it'll spark a realization of
what you're missing in the from-code approach?

Subject: Using AdoNetAppender

Hi All,
 
I've spent about 4 hours today trying to get this working and have
totally failed so far.
 
I can't even really find much info on how to configure this purely in
Code.  In fact there is precious little I can find on the net in fact.
 
Here is the code I'm using the set up the AdoNetAppender in my app:
 
 
public static void ConfigureDatabaseAppender(string connString)
{
PatternLayout layout = GetDefaultLayout();
_sqlDatabaseAppender = new AdoNetAppender();
_sqlDatabaseAppender.Layout = layout;
_sqlDatabaseAppender.UseTransactions = false;
_sqlDatabaseAppender.BufferSize = 1;
 
_sqlDatabaseAppender.CommandType = System.Data.CommandType.Text;
_sqlDatabaseAppender.ConnectionString = connString;
_sqlDatabaseAppender.CommandText = "INSERT INTO Log
([Date],[Level],[Thread],[Logger],[Message],[Exception]) VALUES
(@log_date, @log_level, @thread, @logger, @message, @exception)";
AdoNetAppenderParameter logDate = new AdoNetAppenderParameter();
RawTimeStampLayout dateLayout = new RawTimeStampLayout();
logDate.ParameterName = "@log_date";
logDate.Layout = dateLayout;
logDate.DbType = System.Data.DbType.DateTime;
_sqlDatabaseAppender.AddParameter(logDate);
AdoNetAppenderParameter logThread = new AdoNetAppenderParameter();
logThread.ParameterName = "@thread";
logThread.Size = 255;
logThread.DbType = System.Data.DbType.String;
_sqlDatabaseAppender.AddParameter(logThread);
AdoNetAppenderParameter logLevel = new AdoNetAppenderParameter();
logLevel.ParameterName = "@log_level";
logLevel.Size = 50;
logLevel.DbType = System.Data.DbType.String;
_sqlDatabaseAppender.AddParameter(logLevel);
AdoNetAppenderParameter logLogger = new AdoNetAppenderParameter();
logLogger.ParameterName = "@logger";
logLogger.Size = 255;
logLogger.DbType = System.Data.DbType.String;
_sqlDatabaseAppender.AddParameter(logLogger);
AdoNetAppenderParameter logMessage = new AdoNetAppenderParameter();
logMessage.ParameterName = "@message";
logMessage.Size = 4000;
logMessage.DbType = System.Data.DbType.String;
_sqlDatabaseAppender.AddParameter(logMessage);
AdoNetAppenderParameter logException = new AdoNetAppenderParameter();
logException.ParameterName = "@exception";
logException.Size = 2000;
logException.DbType = System.Data.DbType.String;
_sqlDatabaseAppender.AddParameter(logException);
_sqlDatabaseAppender.ActivateOptions();
 
BasicConfigurator.Configure(_sqlDatabaseAppender);
}

Any help would be great.

James.
