Read Binary Data which is nothing but a Zip file and unzip through SSIS 2005 SP2

Hi ALL, I need some help in developing a task. I have a source database which is Oracle and it has a ZIP file stored inside the database in Binary format. When I move this data into the sql server 2005 database I get the data as binary data. Now the task begins with SSIS, I need to read the binary data which gives us a zip file and then unzip this zip file and read the XML data which is present inside the Zip file. I beleive some one might have already developed this task can you share the solution with us. Note: As this has to be moved into production I dont have permission to use third party tools like Cozy roc or install winrar.exe and simpy calling this exe from the execute process task in SSIS.  Raju

unable to unzip XML file with unicode characters in it's name.


Finally I did manage to build an application that supports unicode characters..

Now my application generates a zip file which contains an XML file. I want to unzip the zip file to view the contents of an XML file.

i am unable to unzip because the name of the zip file/as well as XMl file has Unicode characters(i.e. japanese Name) and it gives some error.


If i generate the XML file  with same contents but name of the files in English then i can view the contents of the XML file.


My query is i want to be able to unzip the XML file when the name of the file contains unicode characters in it.

as per my research up till now,  we either require a compatible winzip software or we have to create an utility for the same.

I need to know how to go about it. It's a little urgent as well.

Thnx in advance.

The following helper class demonstrates a few techniques that allow documents to be uploaded to a SharePoint document library programmatically without using the API or a custom web service.

SmtpClient and Locked File Attachments

Got a note a couple of days ago from a client using one of my generic routines that wraps SmtpClient. Apparently whenever a file has been attached to a message and emailed with SmtpClient the file remains locked after the message has been sent. Oddly this particular issue hasn't cropped up before for me although these routines are in use in a number of applications I've built.

ClientAccessPolicy file in SharePoint 2010

I am upgrading my Silverlight demo code from the old beta to beta 2 and see that there are a few new considerations for the deployment of ClientAccessPolicy.xml files. In a previous post I demonstrated how to do this for SharePoint 2007. The heartburn that I get with that approach is any site collection owner or designer can drag the file into the site collection and open the site up to unwanted client access issues. In 2010 the virtual path provider no longer serves the files from the root of the site collection
