What is the data type for parameter 30? datetime? In that case, try:

cmdAddMember.Parameters(30).Value = DateTime.Parse(txtCurrentDate.Text)

BTW, notice that you don't have to say "Me.".
 
Yes. The problem is that you're supplying strings to your smalldatetime
parameters. You need to use cmdAddMember.Parameter(n).Value =
DateTime.Parse(whatever.Text).

Once you get that working, I'd also recommend that you stop using numeric
indexes for the parameters. What happens to your code if the order of the
parameters changes? Try cmdAddMember.Parameter("@RenewalDate").Value
instead.

P.S. Don't you get tired of typing "Me." all the time?
