dynamic change the IIS Flat file connection manager property

Hello experts,
I am setting up a package to impoert text files into db, the file name was changing according to date, today's file name is AMD20081116.txt and tommorrow's file name would be AMD20081117.txt. I think I need to use expression for the connection manager property but could not find where to configure it. Or should I use a script task for this purpose? any sample I can use? Thanks for your help.
I used to accomplish this through DTS dynamic property for the datasource, can not figure out how to do it in SSIS.

dear Friend,
I made a SSIS project for you.
Create a new project, add the attached packaged, update the SSIS Variable with the path of the textfile folder, and see the results.
Helped?
regards!

Is it possible you could have more than one file? Possible that you are processing mulitiple days of files on a single day?
If so, use a Foreach Loop Container and look for files to process.

Thanks guys for quick response. thanks Pedro for complete pkg, I won't have to process multiple day files in a day, however I have files like Intel20081117.txt , Cisco20081117.txt  as well as AMD20081117.txt . They have the same format. Can I use a union all component to import them first then into the db?

Hi Tom,
You can do a Union to get data from several sources. But you do it better using a pre-defined list (AMD, CISCO, INTEL, MSFT...) that generate files with the format based on current date.
what you do in each file?

Can I know what you are doing with these stock data? :-) I'm doing my master dissertation on DataMining and StockMarkets...
