SQL Server :: Export To Excel In Store Procedure And Transfer To Web Server?
Jul 23, 2010
I have a large dataset (35,000+ rows) that I need to export to excel and then let the user download. I have done this the conventional way (with a gridview), but the data has grown, causing a OutOfMemoryException on the web server.
So I thought, would it not be better if I can export the data into excel on the sql server, and then transfer this data to the web server.
Note that this is not a one-off job. This will be ran regularly (twice a month), but the user. Hence I need something that the user can initiate.

We are deveopingawebiste in asp.net. There are tempelates of each aspx page made in the form of excel sheet. Upon completion of the online calculation, the user is to be allowed to export the results to excel and save them. There would be obviously no formulae in such sheet
I do not want to install Excel on theserver and instead want to utilize the Excel installed on the user's computer for this purpose as every user's computer is expected to have Excel installed. Is this possible to do? How to do this?
I am not an expert in this. let me know if you would need any more information or clarification.

Im newbie in asp .net, and maybe for asp this task can be solved different way... but...
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?

I had a little problem with the value that one of my SPs returns. In my SP, I create some temporary tables to store certain data from multiple tables and contains some queries for an advanced calculationBut precisely yesterday, the value that the SP returns was incorrect. I tried to look at the SP and the data again and everything was OK, but not the result from the SP.And what the heck!!..today the value is totally right ...I truly have no idea what's wrong with the SP..Is there anyone knows what the root of cause is?

In my .net 2.0 application, i have used export / import excel option. In local, its working perfectly but in server i am getting the below errors,
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005.Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

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.

I have a web application (ASP.NET 3.5) that allows the users to upload their own excel sheet. This sheet contains information about items that needs to be inserted to SQL Server 2005.
I already have this functionality, however, it's very slow (it takes almost 20 minutes to finish the request). I need a better way to handle this problem.
The sheet contains information about an item. These properties will be inserted into multiple tables for example (Books, Authors, Titles ... etc ...).
What I'm currently doing is the following:
The user uploads the file. The application opens the file. Read each row and update the database accordingly.
I'm using Microsoft.Office.Interop.Excel
Edit: I'm working with 10.000+ rows per sheet.

I have a class which implements IHttpHandler that is designed to handle image resize requests. It handles Urls like so [URL] Currently the handler looks for myimg.jpg on disk, cuts a 100x100 thumbnail (if it isn't already present) and redirects the client to the thumbnail like so Response.RedirectPermanent("/some/virtualPath/to/thumbnail.jpg");
This has been working great, but I would like to avoid forcing the client to issue a second HTTP request. Is it safe to do the following? Server.Transfer("/some/virtualPath/to/thumbnail.jpg") All the MSDN documentation talks about using Server.Transfer() to redirect to an aspx page, so I'm not sure if this is the right thing to do or not.

I would love to create a "daemon" which in specified time intervals will move-transfer any zip files uploaded by the users from a.example.com to b.example.com
From the info i gathered so far,
The daemon will be an .ashx generic handler. The daemon will be triggered at the specified time intervals via a plesk cron job The daemon (thanks to SLaks) will consist of two FtpWebRequest's (One for reading and one for writing).
So the question is how could i implement step 3?
Do i have to read into to a memory() array the whole file and try to write that in b.example.com ? How could i write the info i read to b.example.com? Could i perform reading and writing of the file at the same time?
No i am not asking for the full code, i just can figure out, how could i perform reading and writing on the fly, without user interaction.
I mean i could download the file locally from a.example.com and upload it at b.example.com but that is not the point.
