Hi Mufi,

You need to assign the value of the parameter to be used in the DeleteCommand. Also I would make the capitalization the same for the "@Empid" and the adding of the parameter to the DeleteCommand.

myDataAdapter.DeleteCommand.CommandText = "DELETE FROM Employees WHERE Empid=@Empid"

Dim myparm As SqlParameter = Deletecommand.DeleteCommand.Parameters.Add("@Empid", SqlDbType.Int, "empid").Value = 123456
