.NET guru: October 2012

Recently I bought a Samsung mobile phone Y Series. To activate the Samsung app store and Google play store, it's asking me to connect via WiFi . But i don't have a WiFi router with me. but i have 10 Mbps Airtel Broadband Connection

Now i have two options

I have to activate Air tel 3 G in my mobile to access all the Samsung apps
I need to buy the WiFi Router , so i could use my existing broad band connection

I don't want to spend extra money to activate 3G also WiFi router is extra overhead for me

I found this useful software for Windows 7, it will act as Virtual WiFi Router

Download the WiFi Router from here Download

You can create a WiFi hotspot for WiFi Reverse Tethering for wifi supported mobiles and other wifi enabled computer to create a network and to share internet. Convert your PC into a WiFi hot spot for free.

Follow this instructions to configure it for the first time

How to Configure?

Now enjoy the same speed in your mobile and save money

Read Event Log Information using LINQ PAD

Anyone tried the LINQ PAD. I found this is very useful to execute for query any short of information from different sources like database, xml, event logs, iis logs with the minimal code

In this blog, i am going to show a example, how we could pull the summary of the events using the LINQ PAD

Link to download LINQ PAD http://www.linqpad.net/

LINQPad is a free software utility for Microsoft .NET to interactively query SQL databases and other data sources such as OData or WCF Data Services using LINQ. LINQPad supports the following LINQ dialects:

LINQ to Objects
LINQ to SQL
Entity Framework
LINQ to XML

It also supports writing queries in SQL as well.

Download and install the LINQ PAD. Open the LINQ PAD and select a new query and select the language as C# Program

Code

void Main()
{
var serverList = new List
  {
  //List of Servers Name
  };
var eventCollection = new Dictionary();

int count = 0;
foreach (var list in serverList)
{
var eventLog = new EventLog(EVENTLOGNAME, list, SOURCENAME);
   foreach (EventLogEntry logEntry in eventLog.Entries)
   {
if (logEntry.TimeGenerated >= DateTime.Today)
{
if (eventCollection.ContainsKey(logEntry.InstanceId))
{
eventCollection[logEntry.InstanceId]++;
}
else
{
eventCollection.Add(logEntry.InstanceId, 1);
}
}

   }
Console.WriteLine("Summary of Server " + list);
foreach (var logs in eventCollection)
{
Console.WriteLine(logs.Key + " " + logs.Value);
}
eventCollection.Clear();
}

}

// Define other methods and classes here

Sample Output

Summary of the Server "ServerName1"
Event ID Number Of Times
100 7
106 15

Summary of the Server "ServerName2"
Event ID Number Of Times
100 70
106 8
