I'm trying to make a helper for parameters in ado.net,

Ex.

param= cmdCommand.parameters.add("@columnName",oledbtype.BigInt, size, "Value")

This is applicable to Update, Insert and Delete the record in my DataGrid. The problem was, I cannot get the Value of "SIZE" that set in my database.. How can i get that? Asumming that I will get that in my dataset.
