View 2 RepliesWCF / ASMX :: Accessing Streaming Photos Server Side?
Jan 4, 2011The more I think about it, the more confused I get. Is this even an ASP.NET question? Maybe it's a Silverlight question, or maybe it's an IIS question. Maybe it's a C/C++ question?!
I rent a server from a server farm. I also subscribe to a security service that streams, over the Internet, once every three seconds, via https, a series of JPG photos from four outdoor security cameras at a certain location.
I want to collect these photos on my rented server (server side). Keep in mind these are photos, not video, though after two weeks of streaming you can get around 50 GB of photos I am told, so I'll have to track storage consumed and delete the old ones, but that's a minor issue.
I researched how to capture streaming photos in ASP.NET and found nothing. I researched it in Silverlight and found a number of links for client side video chatting (a new feature supported by Silverlight 4) both multi-user and single-user, assuming they have web-cams attached to their client side PC. Not quite the same problem as what I have, since I don't care to attach any process to the four security cameras (the security company already wrote the software to do that, and is streaming it live). I just want to know how I can capture and store the streamed photos on my server.
Streaming The File From Memory?
Oct 21, 2010The users have requested the option to "generate" an excel file representation of GridView contents.
Does anyone know how to do this without saving the file to the server but rather just streaming it to the user from memory?
My below code is working
streaming directly from memory instead of using physical path of server machine then saving the file on client machine

Web Forms :: Browser Hangs On File (video) Streaming?
May 4, 2010I'm having a problem with file streaming where this file is a video that is streamed to a FLV player.
Essential components for understanding the problem:
- An asp.net page called Viewer.aspx that has de FLV player incorporated in the HTML.
- An asp.net page (It could be an http handler but in this case it's not) called Downloader.aspx that gets a flv file from somewhere on the web and writes it to the Response Output Stream.
Everytime Viewer.aspx is called, it makes Downloader.aspx the source of the the FLV player and the video is correclty presented and streamed into the player.
The problem I am having now is that any user interaction with the page (even typing an URL inside the same website domain on the browser address bar) becames hung until the video download ends.
I can measure this video download with HTTP Watch for example, and confirm that just after the video download into the player ends, the command issued by the user is immediately processed (or the browser goes to another page if the user typed a new address in the browser address bar).
I tought that it could be the limit of 2 connections per domain, but HTTP Watch only shows one active connection (the video download into the FLV player).
Even if it was this 2 connections limit, I think a nice solution would be to somewhat detect the user interaction with the page and abort that video download.

View 2 RepliesWeb Forms :: Controlling File Name Of The File Opened Directly From File Download Dialog?
Jul 26, 2010I 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?

View 2 RepliesViewing File Using .net / To Copy/download File To Local User Machine And To Open
Nov 16, 2010In 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(),

View 1 RepliesIE Errors On File Download Through .ashx File With Caching Turned Off?
Feb 1, 2011I 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?
Intermittent Bug - IE6 Showing File As Text In Browser Rather Than As File Download
Dec 30, 2010In 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.
