Working hard....

I could not write blog since last 4 months because in new organization i am not getting time at all :-(. We all (i and team) working too hard to acheive project milestones with timefrawork. In project execution ,too many unexpected things croped up but management and client did not change target date. I had to fight with my managers (yes not single manager ...here i have to report multiple managers)with respect to timeline and unexpected items...but managers are manager -:)...

Joined New Organization

After working almost 5 years in small size software company in Pune, i decided to work with one of the biggest IT company in India. I joined new company on 11th April 2011. Probably i am going to work on Sharepooint 2010 and Commerce Server 2009 ( CS 2009). I have experience of Commerce Server 2007 already and this can be helpful for me to implement CS 2009.

Sharepoint is completely new for me though it should not be tough for me to learn it.

I would definitly try to write my expereince on Sharepoint and CS 2009 on my blog (At least twice a week).

Backup Script

If you want to create backup script of data that you want to take backup on daily basis using some batch process and windows scheduler then below is the right option to go with. Copy below stuff in notepad and save it as .bat file and add to scheduler.

@ECHO OFF
CLS
SET DD=%DATE:~7,2%
SET MM=%DATE:~4,2%
SET YYYY=%DATE:~10,4%
SET HH=%TIME:~0,2%
SET MN=%TIME:~3,2%
SET SS=%TIME:~6,2%
SET FOLDER="%YYYY%-%MM%-%DD%-%HH%-%MN%-%SS%"
::START COPY WSSERVICE
xcopy "\\sharedlocation\website\wsService" d:\buildbackup\%FOLDER%\wsService /i /S /E /H /R /Y
::END COPY WSSERVICE

Silverlight - WCF Exception Handling

We cannot handle WCF exception handling(using Fault Exception) in Silverlight in routine way. I mean when you pass fault exception to client silverlight applcation it does not get exception details through fault contract. For this we have to change HttpStatusCode from 500 to 200[OK].

Follow below stuff to get it done

<DataContract()> _

Public Class MYFaultException

Private _reason As String

Private _code As String

<DataMember()> _

Public Property Reason() As String

Get

Return _reason

End Get

Set(ByVal value As String)

_reason = value

End Set

End Property

<DataMember()> _

Public Property Code() As String

Get

Return _code

End Get

Set(ByVal value As String)

_code = value

End Set

End Property

End Class

Dim [property] As New HttpResponseMessageProperty()

' Here the response code is changed to 200.

[property].StatusCode = System.Net.HttpStatusCode.OK

reply.Properties(HttpResponseMessageProperty.Name) = [property]

End If

End Sub

Enable Tracing for Console Application

For enabling Tracing you need to put following settings in app.config.

<configuration>

<system.diagnostics>

<trace autoflush="false" indentsize="4">

<listeners>

<add name="myListener" type="System.Diagnostics.EventLogTraceListener" initializeData="Solstice" />

<remove name="Default" />

</listeners>

</trace>

</system.diagnostics>

</configuration>

NOTE - "ApplicationName" should be available in registry. We can use following lines to create Registry for "ApplicationName" (copy below text in notepad and save it with extension .reg and run it)

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\ApplicationName]
