your conversion is strange. Your source line says >if cint(eventid) = 0
then
while your destination line says >if cint(eventid) = "0" then

In the source line, you are taking a string (eventid) and converting to an
integer, and comparing against zero (note that cint will return a zero for
any non-numeric value, including a null string). In the new line, you are
taking a string, converting to an integer, and then comparing against the
string "0" which is not valid. In addition, the cint() function may not be
as forgiving in vb.net as it was in vb.

Why not check to make sure that the value isn't null or non-numeric, instead
of attempting to convert it and looking for a failure?
