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 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 have been supplied this example for a force download[URL]However, what I would like to know what to do is to hide from the users the physical file path from the users as they do not have direct access to this server. Is there away for me to keep this file path private on a download?
I am dynamically generating a file from server based on user input. I need to provide a download button which, upon clicking, downloads a file to the user's file system. Also, the user might click the same button twice, upon which the file should download again.The dynamic generation of file rules out the HttpResponse.TransmitFile() option, which suports mutliple download.Almost every other option I have come across needs Response.End() to be invoked, which prevents a second download.How do I satisfy the 'multiple download" requirement?Read up on Virtual Path providers, which might enable me to use TransmitFile(), but that looks like an overkill for such a simple requirement.
I am using asp.net 3.5 with C#. I can able to upload the .doc file in the server but i now want to download the .doc file from the server and show it in a text file.I can able to download the file but it show with a save/open window. I just want to show the contents of the .doc file in a text box..

I have a mail list where i can select many mails and download (with/without opening the mail). During the download process i update the mail status(download/open) and show the content in pdf. In normal browser dialog opens where user can save open or cancel options exits. But if the user cancel then the update process done on the mail should not happen. so i think about doing the update process if the user clicks open or save but how can i identity that client control (i think it depend on the browser)
The issue is present if i download and unopened mail and click cancel button in the dialog box the pdf creation code i have done is in this link

which i used to open that dialog in browser to save pdf
Assume a simple aspx data entry page in which admin user can upload an image as well as some other data. They are stored in database and the next time admin visits that page to edit record, image data fetched and a preview generated and saved to disk (using GDI+) and the preview is shown in an image control.
This procedure works fine for the first time however if the image changes (a new one uploaded) the next time the page is surfed it shows previously uploaded image. I debugged the application and everything works correct. The new image data is in database and new preview is stored in Temp location however the page shows previous one. If I refresh the page it shows the new image preview. I should mention that preview is always saved to disk with one name (id of each record as the name).
I think that is because of IE and other browsers use client cache instead of loading images each time a page is surfed. I wonder if there is a way to force the client browser to refresh itself so the newly uploaded image is shown without user intervention.
I am exporting a datatable to an excel sheet. When the ExportToExcel event is fire it pops up a "file download dialog" asking if I want to open or save. What I want to do is right after user clicks on open, or save I would like to show a modal popup saying "Do you want to finalize this download?".
Here is some code, it all works except it won't show modal popup after exporting to excel. Why won't mpeFinalizeDownload.Show() run unless I comment out the line above it?
I am using the following code to export a datset to excel sheet.
[Code]....
Problem is that its not raising file download and hence no export is taking place.The same code works fine in a normal method.But with the webmethod its not working.
have a Page that automatically generates a file and sends it to the Response. I need a Dialog to be shown during the file creation and hidden after the browser download dialog appears.
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.
The problem I am having is that I get an exception after this code runs. I believe it's due to the fact that I call Response.End(). So, every time a user downloads a file it redirects them to the generic error page because all generic exceptions redirect to that page.
how I can write text out to a file and not get this error? If I remove Response.End() I get my text and then the rest of the HttpResponse text, but I don't get the error.
I think my title says it all. I have a modal dialog showing up and the user can make some changes and then click a 'Save' button. I need that to totally post back the whole page. I just assumed the button would fire off regardless of the jQuery.
I have a button event when forces a download to the users browser, but I would like to know whether there is a way for the download open in a new sized browser window. Is there away to do this?
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
Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene
