How To Download Excel File From Site
Jan 17, 2011
I am trying to automate the creation of an excel workbook from data retrieved from a SQL server. I have successfully automated the process and the file successfully saves in a pre-determined location as a 57kb xlsx file. However, when I run the Response.TransferFile code, a file is downloaded that is 18kb in size, and when you try to open the file, it says that the file has an invalid extension. Here is the relevent code:
[Code]....
I have tried multiple content types and different ways of specifying the content type (Response.ContentType = XXX, Response.ContentType = "application/excel","vnd.ms-excel",etc). Nothing works. I can't figure out why the filesize is different even if the extension is wrong.
I can navigate to H:/test/filename and open it just fine, so the excel portion of the code is working fine. I don't understand because this code is so simple yet goes so horribly wrong.

I want to push a file to the browser from a website using a webservice. I'm currently reading the file into a base64 byte array, and returning that from the webservice. This webservice is called from a website, and i'm stuck on how to push this as the original file to the browser. Ideally I would like to read the byte array into a memory stream, and then just write it to the Response stream if possible so the end user just downloads the file.

I have created a CSV file on the server and want to send it to the user using the following code:
Dim strPhysicalPath As String
strPhysicalPath = Server.MapPath( "CSV/" & PathVirtual)
Dim objFileInfo As System.IO.FileInfo = New System.IO.FileInfo(strPhysicalPath)
Response.Clear()
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("Content-Disposition", "attachment; filename=" & objFileInfo.Name)
Response.AddHeader("Content-Length", objFileInfo.Length.ToString())
Response.WriteFile(strPhysicalPath)
Response.Flush()
Response.End()
This seems to work fine except when the downloaded file is viewed in Excell the html code behind the page from which it came is also appended to the file. Does anyone have any idea why it does this?

I get the following error when downloading excel file in SSL site:
Internet Explorer cannot download xxxx.aspx from mysite.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.
After googling, I suspect that it's the problem of the response header. I try the solution in this page and set the header:
[URL]
HttpContext.Current.Response.AddHeader("Pragma", "no-cache");
HttpContext.Current.Response.CacheControl = "private";

I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?

I have a download which is in a class below
[Code]....
and on my page i have a download button which runs a webhandler like below
[Code]....
when the download button is clicked it runs the code below
[Code]....
the dtresults is a datatable that is created on the page. the problem i have is if the cell has commas in like '12 london road, london, le126yr' in the database then its putting it onto the next line in the exported csv file and treating it as a carriage return rather than keeping all on the same line. I have done a replace in the code to replace the comma's to replace them with nothing but it doesnt seem to be working.

I am downloading file from database using the following code. This code downloads an excel file from the database which has a macro attached to it when it is opened. This macro reads file name of the excel file and uses it for its computation. Everthing works file if user saves the file on his harddisk and then open if but if he directly opens the file from the dialog(by hitting 'Open' button) then file name of the opened excel file comes out be the name of the webform that has the above code and this leads to error in the macro. Is there any option through which i can control the name of the file if user directly opens the file from dialog or the option to disable or remove 'Open' button form the dialog?

I am running asp storefront version 9. I am creating a website that offers audio therapy to people. I want to make it so they have an option to preview a clip of the audio (maybe 30 secs). Then also have an option to pay for the audio file then download it from the site.
I am not sure of the best way to go about this. Right now I have each product set up as a generic product calling xml package .product.simpleproduct.xml.config.(I just set it up)
Is there a way to have the two options (preview or buy) for each product right on the product page?

I have an asp.net that produces a Word document. I want to allow users to download the file to their local drive. I use a hyperlink to achieve this and it works fine from my development site. However, when the website is accessed from a non development machine, I am sent to the proper directory, but instead of the open/save/cancel dialog I am presented with a "Convert File" dialog. Any of the selected file types I select download unusable files. I think this has to do with office being installed on the local machine on which I am attempting the download. Is there any way I can simply download a file from a virtual file to my local drive?
