title: SSIS Excel Date empty in first rows not in last rows => date is always empty
body: <p>I do a ssis package which I read an Excel file. I have a column with a date. If the first row the date is empty all lines are concidered empty, if I put a line with a date is ok.
  The file is automacly genereted, not by me, so I can change the order of line. How I can force to have a date ??</p>
  
  <p>I know in input the date is like a string (DT_WSTR) because it could be empty. So after I know how to convert it. So don't explain me how convert it. I just want to know how to have the date when it's on the line.</p>
  
  <p>sorry for my english </p>
  
  <p>Thx,</p>
