I've been searching for various posts on Excel and ASP.Net, and wanted to try and figure out if what I'm attempting has any chance of working. I have a special Excel workbook with a worksheet that has a bunch of calculations and such for various fields that creates an order for his crew. My client uses this Excel worksheet for everything. He's asking me to be able to see online orders (which I have), click a link and have the worksheet be passed down to the client all populated and formatted exactly as is (just adding/editing data).
Is this even possible? I'd have to load this specific .xls file, then open it on the server, save data to various cells, and then do a Save As and then binarystream it down to the client. I'm quite certain there is no version of Excel loaded on the server. So I'm perplexed as to how to accomplish this. Has anyone encountered this situation before and been able to accomplish what's being asked?
I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.
I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db. My question is what can anyone give me code to open an excel file, know what line the data starts on in the file, and import the data into a datable object?

i have winform application with method to generate excel report, now i want to transfer this to asp .net.
User click button and on the server side start method (generate excel report to temp file), then ready temp file transfer to client side. That's how i imagine this process in asp .net. There's no problem to transfer file from server side to client. Problem in process of generation excel report. Excisting code doesn't work, because excel application must be started and visible and how can i do this on server side?
Maybe this is absolutely wrong way and such things doing different way?

My code is running on local correctly. but at iis5.1 it's not working & giving an exception :-
System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
