Hello,

I am working on a B2B web serivce application. I am
Systems Architect for this application. I am in the
process of desigining my components. I would like to know
which one is better over the other for parsing 30MB
files. We would like to use one of the following two
choices: ATL/COM or VB/COM. Can you please share your
thoughts on this ?

Regards,
Ramie

Until another response is posted, I would go with VB only
because of future maintainability.

Obviously I don't know your requirements.

Is this file created from the webservice?, and after it's
creation you need to call a component to do something
with it?

Or is the file a feed from a partner that's updated at
different times (outside of the web service)? If so you
might consider using an NT service and filewatcher.

Sorry. I did not specify my requirements cleary. Web
Service gets the input file (as big as 30MB) via HTTP
post. The user posts file to an ASP page. Then, the ASP
page will call MTS component, which will parse the file to
extract three piece of info: User Id, Password, and some
text data (called as BLOB). Now, the question is on
choosing the language to develop the MTS component (called
as App Controller), in VB/COM or ATL/COM ?

XML may not be the best method of moving 30mb of data across the internet,
especially is most of it is a BLOB.

Let me bounce this idea off you:

1. Store your BLOB in a text or binary file, store any header or
structured info in a smaller .xml or comma delimited file.

2. ZIP the files on the client and then FTP to the server.

3. Bulk load the data into SQL Server using DTS or BCP.

Depends on the format of the files and what information you are
parsing for.

Review your architectural design. I mean, 30 megs via a web service
using asp, then processing through an mts component.....

>2. ZIP the files on the client and then FTP to the server.

Better still use a compressing stream, i.e.
GZIPInputStream/GZIPOutputStream or the like of

Yeah - I've used Gzip and it's good. I serialized a large
dataset using the binaryFormatter to a memorystream, get
and Gzipped it, and converted it to a byte() to send it
accross the wire and it worked great!

Architecture for the Web Service is fixed, or shoud say,
dictated by the user. We must use HTTP as the
transportation protocol, and data is in ASCII (X12)
format, which is encrypted before posted to the web
service. Data is posted to an ASP page in multi-part
binary post. Therefore, I do not have architecture design
choice between HTTP and FTP.
