Hi Team,
I have a Script task(VB code),I have the output as filename to pick the most recent file from my folder but how do I pass this filename as input to my data flow task??
Any ideas or suggestions will be appreciated.

Put the file name into a package-scoped SSIS variable. It's not clear how you want to use this in your data flow, but this should work, depending on your requirement.

Thanks for your reply Phil,
It's not clear how you want to use this in your data flow:
To Answer your question I need to pass three columns from my output file to my dataflow task. -
create all your variables you need in your SSIS package.
Pass them to your script task.
then in your code, read them into a variable, assign a value to them in your code, and finally send them back to SSIS; your subsequent processes can use the variables, and your script task assigns the new value.
string FullFileName= (string)Dts.Variables["FullFileName"].Value;
//some logic to get some values
FullFileName = GetLastRecord();
Dts.Variables["FullFileName"].Value = FullFileNameLowell

So is your question about how to configure the data flow to use the dynamic file name stored in the package variable as a data source? If not, please clarify what you are asking for.

Phil-Yes can you let me know the process of configuring the data flow task to use the filename stored in the variable as a datasource??

OK, easy enough. Create a connection to your flat file in the usual way.
Then, open the Expressions property for the connection and override the ConnectionString property for the connection, using the variable you have created.

Or you can change the connection string for the flat file connection manager in code in you script. This example is setting the zip file connection for a load process:
Dts.Connections("CWC-COUNTY-RIVERSIDE-DEPT_OF_PUBLIC_SOCIAL_SERVICE.zip").ConnectionString = Dts.Variables("User::ZipFile").Value.ToString
