One Day of Vacation

Finally, a nice day of no work and time spent swimming and relaxing. Recharged the batteries and ready for work next week.

LogParser Examples in c#

Seems like many people are downloading my examples in c# for logparser. I will work on some more examples and post them up for you guys.

AzMan Bulk Import/Export Tool V2

Some people have been asking me for this. I have been a bit busy lately on other things...but I promise I will get to it soon.

Backup files/folder structure with Powershell

I was asked to look at a network share and backup the share and folder structure exactly how it is laid out to another location. I am sure this probably could be written with less code, but here is what I did.

$sourceDir = '\\MySrcShare\d$\\MySrcFolder'
$backupDir = 'K:\DestShare\Bkp'

function NormalizePath($path)
{
   if($null -eq $path)
   {
       return $path
   }
  
   [System.IO.Path]::GetDirectoryName($path + "\")
}

$sourceDir = NormalizePath($sourceDir)
$backupDir = NormalizePath($backupDir)

$backupDir = [System.IO.Path]::Combine($backupDir, [System.IO.Path]::GetFileName($sourceDir))


dir $sourceDir -Recurse | % {
  
   $relativePath = $_.FullName.Substring($sourceDir.length + 1)
   $dest = [System.IO.Path]::Combine($backupDir, $relativePath)
  
   if(Test-Path $_.FullName -PathType container)
   {
       New-Item -Path $dest -ItemType Directory -ErrorAction SilentlyContinue
   }
   else
   {
       $ext = [System.IO.Path]::GetExtension($_);
      
       if(($ext.ToLower() -eq '.xml') -or ($ext.ToLower() -eq '.config'))
       {
           Copy $_.FullName -Destination $dest
       }
   }
}

This will copy the folder structure of source (including all sub-directories) to the destination and it will also copy *.config and *.xml files to their respective folders on the destination drive.

Anyone know how to tweak this or make it smaller?

Audit using Log4Net

I had taken a web service off the hands of someone and it had no logging. I needed a quick way to log everything from every method in the code. I also needed to pull the user executing the method. In most cases this would be simple, but not in this webservice...I figured I would read it from a cookie that we had. Nothing would be easy as I knew I had to place statements in some methods, but I wanted to at least make a reusable class.

I used Log4Net and have the log spit out xml to make it easy to import or work with. The code is fairly simple to use:

//In the try
Auditor.Audit.Method(this.Context, "MethodName", new object[] { request });

//in the catch:
Auditor.Audit.Method(this.Context, "MethodName", new object[] { request }, ex);

The code that does the simple audit:

    public class Audit
  {
      private static AuditorCore m_core = new AuditorCore();
      private static bool enabled = false;
    
      static Audit()
      {
          log4net.Config.XmlConfigurator.Configure();

          try
          {
              enabled = bool.Parse(ConfigurationSettings.AppSettings["Audit.Enabled"]);
          }
          catch(Exception)
          {
              enabled = false;
          }
      }

      public static void Method(HttpContext context, string methodName, IEnumerable arguments, Exception exception)
      {
          if (enabled)
          {
              m_core.Method(context, methodName, arguments, exception);
          }
      }
      public static void Method(HttpContext context, string methodName, IEnumerable arguments)
      {
          if (enabled)
          {
              m_core.Method(context, methodName, arguments);
          }
      }
  }

The core class:

internal class AuditorCore
  {
      private log4net.ILog log = log4net.LogManager.GetLogger("Audit");

      private Dictionary m_serializers =
          new Dictionary();

      public void Method(HttpContext context, string methodName, IEnumerable arguments)
      {
          Method(context, methodName, arguments, null);
      }

      public void Method(HttpContext context, string methodName, IEnumerable arguments, Exception exception)
      {
          lock (m_serializers)
          {
              log.Info(string.Format("",
                  methodName,
                  GetUserId(context)));

              foreach (object argument in arguments)
              {
                  string xmlText = SerializeToXmlString(argument);
                  log.Info(xmlText);
              }

              if (exception != null)
              {
                  log.Error("");
              }

              log.Info("");
          }
      }

      private string SerializeToXmlString(object obj)
      {
          if(obj == null)
          {
              return "";
          }

          // Use below object to avoid namespaces in result xml.
          XmlSerializerNamespaces xmlnsEmpty = new XmlSerializerNamespaces();
          xmlnsEmpty.Add("", "");

          XmlSerializer serializer = GetSerializer(obj.GetType());
          using (StringWriter stringWriter = new StringWriter())
          {
              using (XmlWriter xmlWriter = XmlWriter.Create(stringWriter))
              {
                  serializer.Serialize(xmlWriter, obj, xmlnsEmpty);
              }

              // Strip out the  header.
              string xmlText = stringWriter.ToString();
              xmlText = xmlText.Substring(xmlText.IndexOf('>') + 1);

              return xmlText;
          }
      }

      private XmlSerializer GetSerializer(Type type)
      {
          if (!m_serializers.ContainsKey(type))
          {
              m_serializers[type] = new XmlSerializer(type);
          }

          return m_serializers[type];
      }

      private string GetUserId(HttpContext context)
      {
          if (context.Request.Cookies["MyCookie"] != null)
          {
              return context.Request.Cookies["MyCookie"]["userid"];
          }
          else
          {
              return null;
          }
      }
  }

I came across this today...very cool.
