How can I pass a null value for date in vb.net to sql stored procedure?

Question

My application is asp.net with vb.

In my page I have a textbox for passing date. If I didn't enter date and on clicking submit, I have to pass null value to the stored procedure.

I tried following codes such as DBNull.Value and DateTime.MinValue. In that case instead of null, "#12:00:00#" is passing. I have to pass Null.

Just assign the parameter the value DBNull.Value

[EDIT]

If you are using SqlParameter (thanks Jon) then you can set it like this if it gives any error

parameter.Value = DBNull.Value
