Need to stream and zip a .CSV file to the clients browser!

Hello,

I need to stream data from a "DataTable" to the client's machine. The data
first need to be converted to .CSV , and ziped before streaming it to the
client.

Does anyone has any experience with this? Any code snippet will be very
welcome.

Many thanks in advance

Cheers

Rendering to CSV is pretty staright-forward.
How important is it to zip it? Must the user download datafile.zip containing
data.csv ?

If it's "just" for performance of transferring a large amount of data, it
might be a
lot easier to apply http compression which all modern browsers support.

Just set the metabase attribute DoDynamicCompre ssion for your GenerateCSV.asp x
page -
more details on msdn.

Hello Smith,

I'd like just add a note to Neils post, that there is http://weblogs.asp.net/owscott/archi.../12/57916.aspx
a good description how to set the gzip compression on the IIS

Hi Smith,

Here is a sample app that does precisely that.

This perl script goes through a list of files in IFILE and for each file, it sends it on to sendmail. Attachments need special handling and are signified in the email-file by having a line start with 3@ folowed by the name of the file that should be attached. There are 3 problems: 1) There has to be a way of doing this without all those system calls, no? 2) this Line does not always get processed: "cp $base /usr/mailAttached/`date +%d`/"...

Hi, We have an application, written in ASP, that uses the ADODB.Stream to be able to open files and write byte arrays to the Response object. If one of our administrators patches the web servers this application runs on in Windows Update, I'm screwed, right? You've essentially just disabled this COM object, for not only its evil purposes, but its useful ones? Richard
