Good daytime to you, %username%!

This is sort of urgent. Our BizTalk server administrator quit and I'm left with urgent task on my hands with little knowlege about BizTalk 2004.

The task:

Files named tgDDMMYY.kol are dropped to a specified folder. These are delimited text files. They are picked by a file adapter, processed by biztalk map via recieve pipeline and sent to SQL server. I parse their content just fine. The only issue is to get the date from the filename I process and extract date from it.

Is there a way to get a filename by calling C# functions at scripts functiod? Is there a another way to process the content? FILE.ReceivedFileName doesn't do the trick. And many varations of it.

Google didn't give me working recipes, unfortunately.

Thanks in advance.
