Hi Nahald,
Something as this

Dim Conn As New OleDbConnection ("Provider=Micr osoft.Jet.OLEDB .4.0;" & "Data
Source=C:\SERVI CIOS.MDB;" )
Try
Dim cmd As New OleDbCommand("S elect * from tabla", Conn)

MessageBox.Show (oledbExc.ToStr ing)

MessageBox.Show (ex.Message)
Finally
Conn.Close()
End Try
The item from the first row is
dim a as string = ds.tables("tabl a").rows(0).ite m("companyiaPar te").tostring

ok, thanks I think this line.
If I have to do a insert, update o delete in database, I will change this

Is this true?

Nahald,
Yes and than add them to the dataAdapter with
da.DeleteComman d = cmd (to do for the insertcommand, the deletecommand and
the updatecommand)
But for an update for a select as you are using it is more simple to add
after the da = New OleDbDataAdapte r(cmd)
Dim cb As New OleDbCommandBui lder(da)
(that makes and add the update, delete and insert for you, but they said it
is buggy with a lot of parameters).
When you have done that you can do to update
\\\
if ds.haschanges
da.update(ds.ge tchanges)
end if
///

Hi,
I'm using the System.Web.Mail class to send an e-mail from my ASP.Net
application, but when sending the e-mail, I'm getting the above error. It
seems to be because I have Office XP installed, and the version of CDO is
replaced by this installation. I haven't been able to find this error
anywhere on any MS site. Anyone have a clue on how to then actually send the
e-mail?
Thanks

Hi everyone
I was hoping someone might be able to help me with this. I'm just starting to try to work with MS Access tables through VB.net. In Access I can take an existing table and add a new field with the type AutoNumber. I can then set this up as a key. Then if I go into the table I will see sequential numbers have been inserted into that field for me. Can I do this through VB.net
I'd appreciate any help or alternative suggestions...

The syntax I would like to end up with is something like:

where handle would represent, in this case, the PCI config space, vendor_id is a particular offset into that space, and get is a method to retrieve the current value.
To add complexity, some registers are a set of bits or bit...
