Log4net Implementation in CRM 2011, log4net in CRM Plugins, WebServices and Custom aspx Pages.

This post is about log4net logger implementation in CRM 2011. I will provide details about log4net in CRM Plugins. It is as the same with Web-services and Custom aspx Pages.


1. First we will have a Config file for log4net so that, its configuration/settings can be read and applied to logger.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="D:\Logger\Log4net\logs\log.txt" />
      <appendToFile value="false" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="5" />
      <maximumFileSize value="1GB" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
      </layout>
    </appender>
    <appender name="MemoryAppender" type="log4net.Appender.MemoryAppender">
    </appender>
    <root>
      <level value="Info" />
      <appender-ref ref="RollingLogFileAppender" />
      <appender-ref ref="MemoryAppender" />
    </root>
  </log4net>
</configuration

Copy all this into a file named "log4net.config" and place it in D:\Logger\Log4net\Config\

2. Add log4net.dll to your Plugin.

3.

using log4net;
using log4net.Config;
public class MyPlugin: IPlugin
    {
    protected static readonly ILog Logger = LogManager.GetLogger(typeof(PublishToGRID));
    static MyPlugin()
    {
      XmlConfigurator.Configure(new System.IO.FileInfo(@"D:\Logger\Log4net\Config\log4net.config"));
    }
try
{
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
  Logger.Info("Plugin Executed");
}
}
catch (Exception ex)
{
  string ErrorMessage = "Exception Occured in CRM";
  Logger.Error(ErrorMessage,ex);              
}

After your plugin executed: you will se the log file generated in D drive.
containing the following text:

Logger.info: 6/15/2014  7:11 p.m
Plugin Excuted

Bridge Inspection and Management system in Asp Dot Net (.NET C#) with Source Code and Database in MS Sql Server 2008

I have developed Bridge Inspection System using Visual Studio Web-Site Project in Asp.net with C#, using my own CSS styling.
Database: in Microsoft SQL server 2008 R2.
Above is the Main Screen, Default Page.
Following are features in this Bridge Inspection System:

• Admin who can add more admins,Collectors,Inspectors and Bridges to be inspected in  System
  Delete Collectors, Inspectors and Bridges from the System.
• Bridge Inspector who can Inspect the Bridges that are currently added and make a report
• Bridge Collector who can View the final Reports added by BI.
• Reports Generation from Inspected Bridge Data and Export Reports in PDF format to be ready for download and printing.
• Profile Management.
• and more ..........................
• Sql Server 2008 Database, Normalized and Complete Relationships.

Following are some screen-shots of the system.

Assignment # 03

Artificial Intelligence, Fall 2012

Department of Computer Science & Software Engineering, IIUI

Submission Deadline: Monday 04:30 PM, December 10, 2012

The above diagram illustrates the working of Genetic Algorithm. For example the number 24748552 depict the position of the queens. The below diagram explain all.

8					Q

A pair of queen is attacking pair directly or indirectly if both are in same row or same column or in same diagonal.

You are required to perform following task

1. Take four states of the Queen table as Initial population. You are required to use to rand function to produce the position of each queen in each column in all four states.
2. Find the number of non-attacking pairs (fitness) for each state.
3. Perform selection step. The selection should be random in which one state can come either zero time or more than one times.
4. The cut for cross over should be decided randomly on each pair.
5. In mutation, mute only single element of each state.
6. Calculate the fitness again. If the fitness of even single state is better than all states in initial population then stop and display that state, otherwise repeat step 3 to 6
