I'm running into an issue where in IE the security dialog is popping up and if I click download File the file is never downloaded..it just goes back to the main page.
View 3 RepliesI am completely stuck here. Basically, I am serving a file to the user by sending it using Respnse.BinaryWrite. I am also sending this on a redirected page so as not to destroy the Response stream of the webpage which fired the filedownload. This works perfect on my development machine, it also works perfect on Firefox.However, if I publish to my test server, on IE 8 (and 7 I presume) a security warning bar appears (does not appear in dev mode on my pc), asking the user to accept or decline the file. Now the not-so-funny thing: If the user accepts, the file is NOT served, I just get back to my main webpage. If the user tries a second time to get the file the security question will NOT pop up again and the file is served.How can I make sure the file is served in the first instance if the user accepts the security warning and wants to download?
Code used:
HttpContext.Current.Response.Clear()
HttpContext.Current.Response.AppendHeader("Content-Disposition", String.Format("attachment; filename={0}", Session("FileName")))
HttpContext.Current.Response.AppendHeader("Content-Length", myReportData.Length.ToString())
HttpContext.Current.Response.ContentType = "application/pdf"
HttpContext.Current.Response.BinaryWrite(myReportData.ToArray)
HttpContext.Current.Response.Flush()
HttpContext.Current.Response.End()
I have an application whereby a user browses to an Ajax enabled page, sets up some filters, and then clicks on download report. When the user clicks on this button, they are redirected to a Download.aspx page, which builds up the report and appends it to the response as binary (the file may either be zip/pdf or excel). The issue I am having is that everytime the user goes to the page and hits the download button the warning message from IE pops up "To help protect your security internet explorer has blocked this site from download files to your computer". This is not a huge issue, but the problem is that when the user clicks this warning to accept the file, it reloads the page, and all my filters are lost, so the user has to set up all the filters to filter out the data they dont want and then re-download the file.
The interesting thing is that I thought I could track the filters using session variables, so that when the page reloads after accepting the warning message it could be restored, but IE for some reason is not loading the page in the way it should, and so the Page_Load method is never fired when IE reloads it after the user accepting the warning, so I cannot restore the filter settings on the page because I have no event to do it from!
I have searched and searched for a solution.. I have tried changing the mime headers - I am using content-disposition tag set to "attachment; filename=report.zip", I have tried changing the mime type descriptions to different things to see if I can avoid the warning but to no avail. I have tried using an iframe but couldnt quite get it to do what I want it to do, the page was still being refreshed..
I am using SharePoint Server 2007 Enterprise with Windows Server 2008 Enterprise. And I am developing using VSTS 2008 + C# + .Net 3.5 + ASP.Net + javascript (jQuery).
I met with the following security warning in browser (at the top of the page in IE) when browse a page -- "An add-on for this web site failed to run. Check the security settings in Internet Options for potential conflicts." The function I developed works fine besides the security warnings. I am using IE 8. why there is security warnings and how to resolve?

View 1 RepliesI need to used openForecast.jar in my asp.net app, for that i read here and there and found IKVM, when i wrote in cmd

I also found that openForecast consist of about 6 class files and 3 subFolder which each contains several class files..how to fix it (since the documentation of IKVM itself still getting me nowhere)
So I have an ASP.net application, with an ActiveX Control which brings up a pop up
When I point to the application directly through IP there is no problem with the pop up eg. xxx.xxx.xxx.xxx/MyApp (under Default Website in the IIS -- IIS 7) Problem arises when I set up the IIS to point it to a domain [URL] which points to the above IP (under another "Site" i.e. not the "Default Site in IIS 7)
I then get this weird
Microsoft .net Security Warning Never enter personal information or passwords into a window unless you can verify and trust the source of the request.
Source: [URL]
The site is in the trusted list -- just like when I was using the IP only . Is there any setting in the IIS I need to tweak for IE to trust me fully.
I'm creating an ASP.NET application which uses Facebook Connect and fbml tags. It also uses the LinkedIn widget. When I run this app in any browser, there are no warnings and everything works. However, in IE, a message like this comes up:
Security Warning:
The current webpage is trying to open a site in your Trusted sites list. Do you want to allow this?
Current site:http://www.facebook.com
Trusted site:http://localhost
(same for LinkedIn.com). I know how to fix this from a client perspective and to stop the security warning showing up. However, is it possible to ensure this message doesn't come up as it could be off putting for users who don't know how to suppress this warning? I haven't tried uploading it to my webhost, so not sure if this message will appear for everyone in production. However, I always get it on my local machine.
(None of my pages use SSL, so I don't think that's the issue. I tried using FB's HTTPS urls but that didn't make a difference).
I am implementing membership provider. For example, anonymous users are not allowed to acces pages under the folder, namely XXX.
When user clicks to navigate any of those pages I would like to display a popup window. I know I can implement button clikc events. But there are many buttons and links. What is the most effective way to do that?

View 1 RepliesI added the create user wizard to my page, have everything working, but have a question about the continue button that shows up after words..If it was successful, it shows complete and then a continue button, but when you click on it it doesnt do anything. So i'd like to either have it return to the create new user window since i have this wizard on a page where the admin can manage all users. so after a successful insert, return to the create user so they can create another OR change the continue button to a create new user button which then displays the wizard again.

View 2 RepliesI 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'm working on a website where it should be possible for registered users to upload word documents. The administration of users is done through Membership and Profiles. When the documents have been uploaded, the following needs to be achieved:Non-registered users should not be allowed to download documents I should be able to control which users that has access to which documents I should be able to register which user downloads which documents I should be able to track how many times a document has been downloaded
Can this be achieved be using Membership and Profiles?
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.
File.Copy(
sPath + dataReader["url"].ToString(),
Path.GetTempPath() + dataReader["url"].ToString(),
true);
This below code i have used in my aspx page for file download.

Response.End();

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).
View 1 RepliesI 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:
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.AddHeader("Content-Disposition", "attachment;filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.End();
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:
