What's The Best Way To Write And Download Xml File
Aug 19, 2010
I have a web form, that needs to save the data that the user enters, into a file and on the client pc, that will also be able to read from the saved file and repopulate the fields at a later time. No files will be saved to the server side, so I expect streaming needs to be involved at writing time.
I decided XML would be an easy way to do this, but I'm stymied on methodology. XML documents? XML Writers?
I'm stumped on the right search terms to even get what I want.
I have some information I am pulling from my db into a table. Can anyone direct me to a tutorial that shows how to dynamically create a file and allow a user to download that file with the table contents. All this must be dynamic.
There are files stored in sql server (datatype of column is varbinary in the database).
each record is in one record in that table (FILE_TABLE).
And there is another table (PATH_TABLE) to store the files paths.
for example,
when the user download the folder A (select an item on the tree and click a button on the client side),
there is one sub-folder B and two files A-1 and A-2.
in folder B, there is two files B-1 and B-2.
then, at the code behind (server), the server will get the files from the database and convert them (including the files and subfolders) to a .zip file (or other compressed files)
and then write a response (using the method HttpResponse.BinaryWrite(Byte[] xxx) )
to client side and let the user download.
after the download, the user can extract the compressed file and the structure of the folders and files keep unchanged.
I am trying to change the text of a asp:textbox and collapse some ajaxToolkit:CollapsiblePanelExtenders within some ascx controls on my page as well as output a dynamically generated file. I have no problem collapsing the CollapsiblePanelExtenders and changing the text of the textbox from the codebehind or outputting a file. The problem arises when I want BOTH of these events to happen on the same postback. Unfortunately using Response.Write negates all of the other changes to the page.
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 am planning to sell digital goods on my website (Asp.net). After successful payment the customer will be redirected to the download page of my website, which will display the link to download the digital content stored in my server.
I want to secure the location of the file, by creating a disposable link to the file. Every time a customer visits this page a new download link will be generated for the same file. Also this link should expire after it is downloaded for the first time.
Is it possible to do it in asp.net ( C# preferably )? if yes how can i do it?
I've a gridview which I am rendering to a html text writer and allowing clients to download as an excel spreadsheet using Response.Write. I'm using AJAX in my website now and suddenly it stopped working. This is the code I'm using
public static void Convert(DataSet ds, HttpResponse response) { try { //1. declare filename to export string filename = "export"; //2. clear response object response.Clear(); response.Charset = ""; //3. set response mime type to excel response.ContentType = "application/vnd.ms-excel"; //4. prompt user to download the file response.AppendHeader("content-disposition", "attachment; filename=" + filename + ".xls"); //5. create a string writer StringWriter stringWrite = new StringWriter(); //6. create html writer which uses the string writer HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); //7. instantiate a gridview GridView gv = new GridView(); //8. set gridview datasource to the dataset gv.DataSource = ds.Tables[0]; //9. bind gridview gv.DataBind(); //10. tell the gridview to render itself into htmltextwriter gv.RenderControl(htmlWrite); //11. output html response.Write(stringWrite.ToString()); //12. end response response.End(); } catch (Exception ex) { string str = ex.Message; } }
I've found that Response.Write doesn't work with AJAX. Are there any alternatives to this?
i m creating asp.net Mobile website page to download symbian .sis file to mobile ,but its not geting download properly.its working perfectly on desktop.
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?
In our application, we allow user to upload documents which can be PDF, Doc, XLS, TXT. Uploaded documents will be saved on web server. We need to display link for each document user uploaded and when user click on that link, it should open relevant document. it is expected to have required software to open relevant documents.
To upload document, we use saveAs method of FileUpload control and it works absolutely fine.Now, how to view it?I believe, i need to copy/download file to local user machine and need to open it using Process.Start.For that i need to find user local temp directory. if i put path.GetTempPath(), it gives me web server directory and copy file there.
This block of code display Download file Dialog for Open or Save the attached file.It's working fine in Mozila Firefox and IE8 but doesn't display Download file Dialog box in IE 7
I have made an application where I am displaying the .pdf , .doc , .docx files. These files are uploading from an Admin Panel.When user place a mouse pointer on download icon provided in front of every file, it shows the complete path where it’s get saved.I want to avoid this path visibility even when user place mouse on download icon and even if it Inspect an element (as most modern browser will have this functionality).
I have a simple 'file download' generic handler which sets the response contenttype and headers before sending the file through the same response.
I also have Response.Cache.SetCacheability(HttpCacheability.server) set in the global.asax.
As I have noticed from various sources, Internet Explorer doesn't like this no-cache setting and gives an error when trying to download the file (requested site unavailable or cannot be found).
I thought maybe I could override this setting in the .ashx page, so I alter the response's cacheability setting to public. This did not solve the issue. removing the line from global.asax does solve the problem but obviously affects the whole site.
Is there a way of setting the cachability just for my generic handler?
In an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is:
This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this:
HttpResponse response = HttpContext.Current.Response; response.ClearHeaders(); // Setting cache to NoCache was recommended, but doing so results in a security // warning in IE6 //response.Cache.SetCacheability(HttpCacheability.NoCache); response.AppendHeader("Content-Disposition", "attachment; filename="theFilename.pdf""); response.ContentType = "application/pdf"; response.BinaryWrite(MethodThatReturnsFileContents()); response.Flush(); response.End();
However, I don't believe that any of the changes made will fix the issue.
I'm trying to force a large (200+ MB) file to download that's on a remote server. The problem is that I can't use the "WriteFile()" function, since I'm not using a virtual path. Then, when I try:
I have a full working web site that i ported to a new hosting company. In some pages i have links to PDF on the server (they do exist!) On the old server no problem. On the new one when user clicks on the link : error 404 file does not exist.. Should i look in the web.config ? i don't know where to start
