When we create server side controls we do it properly. We code
in C# for unsurpassed performance, control and stability. All our
classes are 100% CLS compliant and 100% Managed*.
Uploads are only copied to memory when required. This means that
even for large uploads ABCUpload will use only a small amount of
memory. Caching on disk is invisible to the user and uses advanced
Windows techniques to ensure that the division of data between disk
and memory is handled optimally.
ABCUpload is multithreaded to take full advantage of multiple
processors. In particular, time wasteful operations such as disk
access, are serialized to other threads to ensure that no
* All core operations within our .NET products
are 100% managed code and most users will only ever want to use
these core operations. However .NET does not currently support all
the features that the Windows API allows access to and the only way
to get at these features is via unmanaged calls into the OS. We
don't want to limit you unnecessarily so we isolate and clearly
mark any methods that might use unmanaged code. If you want to use
these methods you will need to ensure that your ASP.NET permission
allows you to call unmanaged code via ABCUpload.
In ABCUpload the only method that uses unmanaged
code is the UploadedFile.SaveSFM method for saving files in
Services for Macintosh format.
