Date Fields in VB 2005

[Tony K]

I have a form that involves a datagrid view to be filled after a start and
end date are selected from 2 DateTimePicker fields using the Short Format.
The query works without error but...

I have records to be returned that have dates such as 5/14/2008 and when the
start date is selected as 5/14/2008 the query doesn't include it unless I
select 5/13/2008.

I'm guessing this has to do with the time?? Is there a way to have it
ignore the time or make it the date + 12:00:00AM??


code:
Try
Me.TotalsTableAdapter.FillPOTotalByDate(Me.Inventory_management_databaseDataSet.Totals,
New System.Nullable(Of Date)(CType(StartDateTimePicker.Value, Date)), New
System.Nullable(Of Date)(CType(StopDateTimePicker.Value, Date)))

Catch ex As System.Exception
System.Windows.Forms.MessageBox.Show(ex.Message)
End Try

query:
SELECT [Purchase Orders].OrderDate, [Purchase
Orders].PurchaseOrderNumber, Suppliers.SupplierName, SUM([Inventory
Transactions].UnitPrice)
AS [Sum Of UnitPrice]
FROM (([Purchase Orders] INNER JOIN
Suppliers ON [Purchase Orders].SupplierID =
Suppliers.SupplierID) INNER JOIN
[Inventory Transactions] ON [Purchase
Orders].PurchaseOrderID = [Inventory Transactions].PurchaseOrderID)
WHERE ([Purchase Orders].OrderDate >= ?) AND ([Purchase
Orders].OrderDate <= ?)
GROUP BY [Purchase Orders].OrderDate, [Purchase Orders].PurchaseOrderNumber,
Suppliers.SupplierName

Thank you,

Tony K

Tony,

A DateTime structure is based on ticks in a long which starts at 01 01 00 .

As it is used as DateTime, then it contains a Date part and a Time part
which are given back in the format as is set in the local setting of the
computer.

However, as Steve wrote, you can select only the date part.
