In my application I have several datagrids databinded to various tables. Within these tables I use many times a date field. The database is made in access. At the beginning I had the date format on default as long date. When I saw that time was added I changed it to shortdate. Still I get the time in the various datagrids. How do I remove the time from the datagrid so no time is entered when I create a new field.

The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.

I'm trying to create an auction site using asp.net. My auction's start date & time and end date & time are stored in my sql server 2008 r2 database as datetime types. I'm using vb.net. I'm trying to create a select statement in which I can query the date and time portion relative to the current date and time (so as to only display current ongoing auctions). I can successfully query the date portion using the Date.Now function, but the time is giving me a hassle. DateAndTime.Now doesn't work. I've even tried to separate the time and date in the database, but I still can't get an effective query. Here are two examples of code which I've tried:

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?

The user enters information into a textbox and I would like to reflect these changes on the database. So say there is a value of 50 in the textbox and the user just deletes this and it is now "". When I try to update the database I receive an error as it expects a type of double. However, simple appending a 0 here when a value of "" is encountered will not work for me as I have a universal function to handle all of my updating needs. How would I go about determining the type of field I am dealing with (int, double, varchar) of the data table which I currently have in memory
