BizTalk Event Log error: The source was not found, but some or all event logs could not be searched.

My BizTalk development machine runs on Windows 7. In an orchestration I've wrote
System.Diagnostics.EventLog.WriteEntry("Payment Automation","Instantiated the Process Engine");

When it runs, i can see following error in the event log. But I wont get this in Windows 2003 R2 server.

4. Insert a new String Value called "EventMessageFile" under the "Payment Automation"
5. Double click on "EventMessageFile" set Value Data as "C:\Windows\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll"

Final windows registry editor will look like this,

Restoring Deferential backups in SQL Server (T-SQL)

In my previous post I demonstrated, how to restore deferential backups with SQL Management Studio. In this post, I'll show the same thing with T-SQL.

1. Select the Master database.
   USE Master
   GO
2. Restore the latest full back up with REPLACE and RECOVERY option
   RESTORE DATABASE RESTORE_COSTSHEET
   FROM DISK = 'e:\backup_201007282300.bak'
   WITH REPLACE,NORECOVERY;
3. Restore all deferential backups except last one
   RESTORE DATABASE RESTORE_COSTSHEET
   FROM DISK = 'e:\201006110800.incr'
   WITH NORECOVERY;
4. Restoration of Last back up file should be like this.
   RESTORE DATABASE RESTORE_COSTSHEET
   FROM DISK = 'e:\201006111200.incr'
   WITH RECOVERY;

Restoring Deferential backups in SQL Server

Did you have ever restored a SQL data base? If you are a developer probably not. With this post I'm going to show how to restore deferential backups step by step.

1. One important thing, to restore deferential backups, you need to have latest full backup and subsequent deferential backups.
   
   Go to the SQL Server Management Studio, and select "Restore Database..." option by right clicking on Databases node in the Object Explorer. Follow the steps as shown in following screen shot.



Figure 1

2. Select "Options" from the left of the dialog and select the following option.



Figure 2

3. Now, note your data base's status has been changed to "Restoring".



Figure 3

4. Restore the number of subsequent deferential backups, except the last one, only with "RESTORE WITH NORECOVERY" option on.
5. Restore last backup with default values of the option dialog box. That is with "RESTORE WITH RECOVERY" option. And also note the database status has changed back to normal.

Considerations:

• This demonstration was done with SQL Server 2005 with SP2
• Adhere necessary procedures with you company if you are going touch live data base.

Social Networks: The Other Aspect

As we know, social networks increasingly becoming new communication tool among us. Surprisingly the Public adopt such tools more quickly even without training. According to the Forrester Research two third of internet users (total internet users 625 million¹ ) have joined a social network.

Why this becomes so popular? We can find very old friends, probably haven’t been meet them after high school, which is very good thing . Also social networking can use as mechanism of promoting your business. We have to pay less than TV or printed media advertisements.

Well, did you think about its other side?

1. This will be affected to the country's productivity.
   Most of the companies in the world now blocking them in working hours. Some countries completely blocked such tools.
2. People losing their privacy.
   It is found that more than 85% of users has crossed their line and suffering or will suffer consequence. This is a great place for being Identity theft. Also, I read some news someone had been robbed, because he or she put everything in the network including days he/she out of the town.
   Had several cases ended up with death.
3. Law Enforcement
   Who will be the responsible for cases such as defamatory, obscene work? We can clearly see rules and regulations completely differ from country to country. Hence no guarantee for protecting such cases.
4. Protection of Data
   The most important thing is, do these social networks can protect or have compliances on their users’ data. Very recently, one social network had information flaw and it’s been there since first release.

Ok. What we can do then? Should be completely dined?

1. Don’t expose your too much information.
2. Don not trusts anybody in the cyberspace.
3. Avoid giving personal data.
4. Limit the use of them and don’t be addicted.
