Open EXCEL file that exists on the network from a webcontrol

I have an ASP.NET page that invokes a web control written in C#. What I want
to do is (based on the session ID) display a certain spreadsheet that exists
on a
network drive. I want the webcontrol to open the spreadsheet using my
log on credentials since they won't have priviliges to access their particular
file from the network drive. BTW, I am guessing I will have to use HTTP as
this file exists in a Sharepoint document library.

I can use OLEDB but don't really want to rebuild the spreadsheet. I would like
to open the existing one for them so they could do what they wished with it.
It also contains many graphs and charts so I definitely would like to open the
existing one for them. I guess I could FTP the file locally and then open it
for them. Are there any other easier methods I can use to accomplish this?

If it is a plain user control (no embedded activex objects) the best you can
do is read the data and push it out to the page formated with content type
excel. That will get your entire page, not your user control, as a
spreadsheet. To solve that problem, you can wrap the control in a frame and
stream the excel file to the frame instead.

On the other hand, if your user control is an activex object, OWC for
instance, you can simply read the file in from the share.

hope this helps

It sounds reasonable. So would I pull the file using the Excel .COM library
then push that out to the frame? Are there any examples out there that you
might be able to point me to?

The ultimate would be to open up another browser window. I tried both
HttpContext.Cur rent.Response.R edirect("file:///C:/myfile.xls")
HttpContext.Cur rent.Response.W ritefile("file:///C:/myfile.xls")
but nothing happened. What I am thinking of doing is mapping a local
network drive and replace "C:" with "I:" for example.

How do I open an Excel file as a read only document? It would be okay if it opened in the browser window but I don't want the user to save any changes and stomp over my original file on the network.
