generating MS-Excel report through ASP.Net without installing MS-E

[hari krishna]

hi,
I want to send the data from dataset information to Excel through ASP.Net.
there will be no XL installed on web server. web server is win 2000 server
machine. I am using visual basic code in asp.net.
The Xl sheet should not be opened in the browser. All the information from
dataset(datatable,datarows) should be sent to XL and the file name should be
given dynamically through program and the xl file should be saved dynamically
through program. it should not ask for file name and it should not ask to
save.
Kindly let me know if any body has done this or any body knows how to do.
pls send me the code to vh***********@rediffmail.com

regards,
Hari,

hi srini thanks,
But i want a code in vb code.
And also i gave permissions through dcomconfig to launch permissions ,
access permissions to excel application. but it did not work through asp.net.
it still gave permissions denied.
and more over i know that excel is not recommended for automation through
server side. that is why i don't want to install xl, and create reports with
..xls extension and when i open it on a machine where xl is installed it
should open in xl.
Is there any code using response object sending to xl like that.
pls reply.

There is also a number of alternatives that may suit your purpose.

If there is no specific reason about writing in MS Excel format, I'll
suggest you to output the data in
XML format.

..NET framework have come with good support in handling XML files, and MS
Excel can read XML
data elegantly as through it were Excel file.

If you are using MS Office 2003, you may also generate a web page and let
the Excel's import wizard
to update the data each time the file is open.

If u don't install Excel library on ur Server how ur vb code will create
object for Excel files? I had done this on IIS 5.0 with office installed on
server and I code that all upon users request from website. It does
automatically and make attachment and send email to waterver user input
email address. It makes a temp folder and create .xls file and attach for
email and delete it. That is not a good practice but we do for users
request.
I also want to conevert it for PDF, any one has idea how to make dynamic PDF
upon users given criteria on web and send that report as email attachment in
PDF format?
Let's discuss more if any one had done. Hari if u need any furhter
assistance let me know.

HI Shamshad,
Thanks for the advise.
I need ur help in this regard.
I don't want to open the xl in browser, and it should not ask for the name
of the file to save?open etc.. it should automatically generate the xl file
and store it to the physical folder dynamically. This is our users request.
my web server is on Win 2000 server machine and IIS 5.0, ASP.NET 1.1
installed.
the code i wrote is giving permissions problem. I did give Launch and Access
permissions through DCOMCNFG for MSExcel application. But still it denied the
permissions. At the line "Dim oExcel As Excel.Application = New
Excel.Application", it gave the following error. pls help me how to do this.
Access is denied.

I don't know, but adding "MACHINENAME\ASPNET" account to the MS Office
directory with
execute permission may help.

Users can't create process from files in a directory if they do not have
execute permission of the
directory.

Since .xls is a closed format, I don't think you can generate one without
using MS Excel. (Although you
may be able to create compatiable one after studying the code of
OpenOffice.org etc.)

For this reason, you can see that I always suggest you to create the file in
another format that can be
opened by MS Excel. By saving the file as xml, all you need to do is save
some data with the structure
you'll use in XML format by Excel and study the tags it used. The time will
need to study is relatively
much shorter.
