Asyc reader in .NET 2   
Is it possible to process data as it is pulled back in asyc mode? I want to 
process records as they come back from the SQL Server basically and convert 
them to local objects... which right now takes a lot of time doing it like 
this

Load data table from SQL Reader
Loop through each data row
    create object based on data row
End loop
Return collection of objects

I thought it would be neat to do it like this
Async Load of data from SQL Reader
    Async returned a row, convert to object (1 per row)
Wait For Async to end (WaitOne basically)
Return collection

is this possible? if so how? thanks!

Hi, Smokey:

    SocketPro at www.udaparts.com is able to do something like your way. 
Inside the package, there is a free remote database service available at 
http://www.udaparts.com/document/articles/dialupdb.htm with all of source 
and sample codes for you to experiement. Give it a try.

Re: Asyc reader in .NET 2   
ah ok, was hoping I could eliminate a bottleneck in returing a large data 
set by doing it async... oh well, guess now all I can do is execute multiple 
requests at once :)
