Well... you've got a variable 'dDate' that supposed contains a date value,
but it is declared as an Integer. You are passing that variable to the
Month() and Year() static methods. These methods require that you pass a
Date value, not an Integer. There is no direct conversion from one to
another. Therefore, the convert fails.

First of all, read this article:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvb600/html/vb6tovbdotnet.asp

If the date value in the file is an ASP date value, you can use the ToOADate
and FromOADate methods to convert.
