DataTable select command

[kasdoffe]

I want to use the select command on my datatable to select a subset of rows that match my criteria. However, I'm having trouble. Here's my code:

 

DataRow [] dra = myDataSet.Tables["Tasks"].Select(select);

 

select = (DueDate>Format('1/1/1','yyyy/MM/dd') And Due_Date<Now() And Completed=False) Or (Completed=False)

 

I get the following error message though: "The expression contains undefined function call Format()."

 

How can I check if my DueDate column is set to the default 1/1/1?

 

help please?
