Mark,
| I couldn't find the method "BeginValidate" or "EndValidate" in the
ASPNetMX
| documentation at
http://www.aspnetmx.com/help/default.htm. Where does it
| come from?
"BeginValidate" or "EndValidate" are based on ASPNetMX being a Web Service,
ASPNetMX is not a web service, ergo they don't exist per se. You should be
able to use an asynchronous delegate with ASPNetMX.
http://msdn.microsoft.com/library/d...s/cpguide/html/cpovrasynchronousdelegates.asp
| Also, excuse my .Net ignorance but does "asynchronously" mean at the same
| time?
Yes. For details on asynchronous programming see:
http://msdn.microsoft.com/library/d...cpguide/html/cpconasynchronousprogramming.asp
| And, is "For index As Integer = 0 To 20 - 1" the same as:
|
| Dim index as Integer
| For index = 0 To 19
Yes
| I haven't really programmed much in VB.Net before just VBA.
Looking at
http://www.aspnetmx.com/help/default.htm, I would consider using
ValidateQty instead of Validate, as ValidateQty does a list of addresses.
Then I would not worry about getting multi-threading & asynchronous
programming to work. As Kevin suggests multi-threading is something to
consider not using, as it is a very advanced topic that is easy to make
things worse then better, although I have not specifically read Kevin's
response... Asynchronous programming ("BeginValidate" or "EndValidate") are
generally easier, however even then you need to be very careful as its still
multi-threaded programming.
Hope this helps
Jay
