I am using Visual Studio 2003 and am getting lousy performance after using
a datatable select and then trying to assign a value to a column of the row
that was found:
DataTable dt = new DataTable();
dt.Columns.Add("Number", System.Type.GetType("System.Int32"));
dt.Columns.Add("Value", System.Type.GetType("System.Double"));
for(int i=0;i<2000;i++)

Hi,
I want to make sure I got the easiest way on how to bind a grid's datasource to a datatable.
I've made an in-memory datatable

Dim iPos As Integer = dv.Find(dr.Item("ID"))
Me.BindingContext(FacilitiesDS1, "Facilities").Position = iPos
That is the code.. dr is DataRow. If dr.Item("ID") = 3, the find will
return position 0, which it should have been 1, and if the ID = 2, it
will return 1, which should have been 0.. The DA has a connection string
that sorts it...

Hi.
I'm trying to make a criteria string to use in Select() method of a datatable, searching for a date, but it is apparently not working!
In one of my tests, I have a datatable with 1 row and a field containing the following value (extracted from Immediate Window):
?dtbSample.Rows(0).Item("COM_STARTDATE")
#5/8/2006 9:00:00 AM# {Date}
Date: #5/8/2006 9:00:00 AM#
(for better understand, consider this date as '2006/05/08')

Hi,
I am working with strongly typed datatables.
What is the most efficient way to build a new DataTAble based on the result
of DataTable.Select?
At this point I use a foreach loop to do the work manually. I am looking for
an automated way.
Thank you,
Max

Hi,
I"m new to c# and .net. I wrote a small program to add rows to an access
table.
the program goes thru the motions but the data never gets there.
here is my code. I am intentionaly not using the form controls. I"m trying
to do it solely thru code. You can safely assume I have an access datsabase
with one table called who with three columns(fields).
where did i go wrong ?

Hello,
I have a DataTable in which the items are of type MyClass.
How can I use Select to compare a MyClass instance with the DataTable?
Is there any overriden method (like the ToString()) to use it on
Select?
Thank you,
Nuno Magalhães.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
