On top of what Duncan posted, CopyString has some SERIOUS limitations on it's use in the .NET Framework. Since an object can be moved at any time, CopyString can be passed invalid addresses unless the objects invloved are pinned in place.
What does this function do that you require the use of CopyString??

That's because you don't read anything from USB. It's a bus, not a port. You read data from the devices attached to the USB bus, but how you do that depends entirely on the device itself and what methods it's driver exposes.

I've not used Crystal for many years - but I seem to remember that there was an option for executing a "pass-through" query that would allow you to use native SQL-Server syntax (ie. "EXEC MyStoredProc 'ABC'").
I am trying to send an email using my program. How Many ways are ther to do it? Which is the best way, currently i have:
Dim m As New MailMessage(FromtextBox.Text, ToTextBox.Text, SubjectTextBox.Text, BodyTextBox.Text)<br />
Dim a As New Attachment(My.Settings.CurrentList)<br />
Dim c As New SmtpClient<br />
c.Host = ""<br />
My main problem however is that i have no host info, is there anyway to access the host information on the machine the program is running on and, if not, is there an alternative, other than manuel user entry?
If you don't have the host info, you need to use MAPI, there are .NET MAPI wrappers on the web.
