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:
I have a web app which displays some data in a GridView. This GridView is populated with a method called BindGrid. The user selectes one or more rows from the grid, then clicks the Process button. What needs to happen is that the selected rows are assembled into a CSV file which is downloaded to the browser, then the database is updated to reflect which rows were selected, and the grid is refreshed so the previously selected rows are no longer displayed. This all sort of works, except...
My code is below, which is very similar to lots of snippets found in this forum.
The problem is that if I uncomment Response.End(), or replace it with ApplicationInstance.CompleteRequest, it all works great except none of the code after Response.End() executes, and so the log entry is not made and the grid is not refreshed.
If I comment Response.End(), as in the snippet below, the code following does run, including the log entry and the call to BindGrid. (I know that because log entries inside BindGrid are made.) However, the page does not refresh. If I press F5 to refresh the page, it redraws correctly refreshed.
So the question is, how do I refresh the page after downloading the file?
I have tried calling both Response.Redirect and Server.Transfer after BindGrid
I'm getting tired figuring out this error. Well, Basically. I have uploaded my ASP.net website to a server (IIS installed) as well as the VB project I made.
BOTH are connecting to a DB named CLIENTS.
the website uses a datagrid to show data, while the VB Project updates the DB based on a monitored folder.
The Problem is If the website is opened first the VB project shows an error "Unable to open the physical file (MDF). Operating system error 32 (error not found)" and Vice Versa if the VB project is first started.
I have a link http://Test/Folder/file1.xls which is working fine But if I typehttp://Test/Folder/file1.xlsx it is not working. It is giving me a file not found error.So when I read online every one is suggesting me to add the correct MIME type at tyhe IIS level. I don't know if that's the correct thing to do.I opened IIS and navigated to folder FOLDER right clicked and selected properties -> HTTP Headers -> MIME Types->New -> Extension -> .Xlsx-> What should i be entering for MIME type?
I have an intranet site that i set up to windows authentication. It works fine most of the time but some departments wont be able to access the site and will be asked to enter user name and password.I checked their Active Directory account and the only difference i could see was that the organizational unit parameter was different than the rest of the users.
i am new to this, would like to ask how can i check which button user click when downloading file, either open, save or cancel ? I need to update to the Database after the user click the save/open button, if cancel, then do not do anythinghere is example of code:
I am creating an excel spreadsheet server side and downloading to the client via a Silverlight front-end. It is started by the user clicking a button and being presented with a SaveFileDialog. Once the user enters a file name then silverlight starts an asynchronous call to a web service and when finished returns a byte array which is written to wherever the user requested to save it. This all works fine.How do I then automatically open this file on the client's PC?
In our ASP.NET web site we have developed an aspx page that allows the user to download a file. The file path is sent as a parameter and then the file contents are read and written to the response stream. The code that we have used is the following:
Everything works as expected in our development environment, but when we use this piece of code in our production server, we noticed that when trying to download almost all kind of files, nothing happens in the browser. It just opens a new window for that aspx page, but then it gets closed almost inmediately. It is very weird since we have tried downloading .pdf, .doc, .xls, .txt and image files with no luck, except with some (not all) .msg files.
We have being looking for a clue sniffing the HTTP traffic that reach to the browser with Fiddler, but we have seen nothing strange. In all cases the file contents are sent to the browser with no differences, so it seems that it is the browser doesn´t show the open/save/cancel dialog. Here is a sample of the headers received in the browser with a failing file:
HTTP/1.1 200 OK Proxy-Connection: Keep-Alive Connection: Keep-Alive Content-Length: 421395 Via: 1.1 IBISA01 Date: Wed, 26 Jan 2011 12:02:54 GMT Content-Type: application/octet-stream Server: Microsoft-IIS/7.5 Cache-Control: private Content-Disposition: attachment;filename=P08-0656 Interflex EspecificaciÃ³n Inteface SGA ERP Version 0.1.pdf X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET
And these are the headers of a file that can be downloaded:
HTTP/1.1 200 OK Proxy-Connection: Keep-Alive Connection: Keep-Alive Content-Length: 290816 Via: 1.1 IBISA01 Date: Wed, 26 Jan 2011 12:03:29 GMT Content-Type: application/octet-stream Server: Microsoft-IIS/7.5 Cache-Control: private Content-Disposition: attachment;filename=Acalaracion final Fichero ascii proveedores Interflex.msg X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET
In all cases, the full contents of the file appear after the headers with apparently no problems related to encoding. We are wondering if there is some possibility to debug or trace the Internet Explorer activity to see why is rejecting to download the files. The web server has Windows Server 2008 R2 and IIS 7.5. The browsers that we are using are IE 8.0 over Windows 7.
I can't open "ONE" page of .pdf file using IE8 and give me an error message "the file is damaged and could not be repaired" when retrieved from SQL Server 2008, but more than one page I can open with no problem.
With Chrome I can open any number of .pdf pages.
The same page that I can't open using IE8 from DB, can be opened directly from hard disk using IE8.
i have some problem on downloading file which file types are .doc, .docx and .pdf.
I have wrote the code for downloading when the button is click. the button can download these three types of file when click.
But, i have some weird condition. when i test in my local pc using the firefox, the downloading box popup with the file type detected. but when i upload the code files in live server and test the download button using firefox, the downloading popup but it cannot detect the file type.
therefore, i can proceed the download process using the firefox but i failed to open the files coz it dun have the file type.
I able to successfully see all the Excel files in the given folder using the datagrid and code below. Now I would like to be able to click the link to the file, or add a button, to get a download file dialog box. [Code]....
CreateDirectoryIfDoesNotExist(); WebClient webClient = new WebClient(); [code]...
When i deploy it on the server; and run my program, i get a message saying that download has completed successfully. But the problem is that the file is downloaded on the server machine in the filefolder (LocalFileFolder). I want it to be downloaded on the local machine. What is it that I am doing wrong?
I've looked all over the web for something that would show me how to do this but can't find it. I have a page that uploads information about an individual including a resume in the form of a doc docx or pdf. I can upload the file okay but I do not know how to, on another page, To download the file that was loaded to that person's row in the database. Here is the upload code
I have copied a DB from one my computers and using it here. On trying to open the page which requires the fetching content from DB, on con.open I am getting this exception:
Unable to open the physical file "E:Program FilesMicrosoft SQL ServerMSSQL10.SQLEXPRESSMSSQLDATAcakephp.mdf". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)".
In Visual Studio, when I test the connection, it says "Test connection succeeded". However, there is one strange thing going on. When I login to the Management Studio, there is no + sign with the newly attached database, as shown.
