[Code]....
I am using this code to download and its working well for me.But i cant understand the code.Can someone explain me this code to me please?
Response.AddHeader is used to add a new HTML header,but what is an HTML header all about?and the parameters i am passing within it as the name and value;what are they?
Is it possible to use the Response.AddHeader particularly Im trying to use the "Refresh" of it. I need it to pause before it redirects but the place where the code is being ran is in a ASCX in the codebehind. It does nothing when I have the following in my Codebehind:
HttpContext.Current.Response.AddHeader("Refresh", "6;URL=Default.aspx");
Any way I can redirect a user in the codebehind on a ascx page?
I used the following code for the form download
[Code]....
But form is not posting back on execution of the above statement. What should I do , so that form postback also occurs after this statement.
I am using the following code to download the file from web server
[Code]....
my website www.findmyhomefromhome.com after a sucessful entry i redirect the users to their previous uploads which is the manageaccomm page. The code behind that does this is Response.AddHeader("REFRESH", "3;URL=manageaccomm.aspx");
This works in firefox but not in safari. In safari it goes to the following [url]
and the message "resource could not be found Requested URL: /manageaccomm.aspx, 3;URL=manageaccomm.aspx".
I'd like to fix this but keep it working on other browsers .
I am creating a web application that allows a user to download a csv file of a gridview. However, after looking at tutorials online such as http://www.aspsnippets.com/Articles/Export-GridView-To-Word-Excel-PDF-CSV-Formats-in-ASP.Net.aspxand such, I successfully got the table I wanted but there are HTML content appended to the table as well.There was also a similar problem being brought up on the forum,http://forums.asp.net/p/1528174/3692826.aspx. The solutions didn't help me much though. However, I am not really sure how Handlers can benefit this. Furthermore, I don't want the user to be navigated to a blank page just to download the csv file. I tried to debug and insert removal code to remove the html code before the response object is being wrote out but seems even at the end of the writing method, the response object seems to be holding just the table content only.
View 4 RepliesHow can I remove the html content and add new string to the Response object. If I use the Respose.Write method the page contains the string, but while taking the view source option from browser it will display some html tag like Doctype, head, body etc. My requirement is only the string should be displayed in the source.
View 2 RepliesI'm using Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.HtmlEncode(FileName)); to pop a 'open/save file' dialog for the users, so that they can download an file on to their local machines.
This is working good normally in IE7,But on IE6 the file is not opening when user click on the open button in 'open/save file' dialog. I gone through the net and found that Response.AddHeader("Content-Disposition", "inline; filename="+Server.HtmlEncode(FileName)); should be provide to work that in IE6,and its works fine..
But the issue is most of the files that can open in browser opens on the page itself.. ie user on a mail page and click download an image file it opens there,, i need it to open in another window as in case of IE7 what can i do... other files that cannot open in bowser open with current application in system ie(word,excel etc)..
The Code i used is here....
Response.AddHeader("Content-Disposition", "attachment; filename=" +FileName);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = ReturnExtension(file.Extension.ToLower());
Response.TransmitFile(file.FullName);
Response.End();
private string ReturnExtension(string fileExtension)
{
switch (fileExtension)
{
case ".txt":
return "text/plain";
case ".doc":
return "application/ms-word";
case ".xls":
return "application/vnd.ms-excel";
case ".gif":
return "image/gif";
case ".jpg":
case "jpeg":
return "image/jpeg";
case ".bmp":
return "image/bmp";
case ".wav":
return "audio/wav";
case ".ppt":
return "application/mspowerpoint";
case ".dwg":
return "image/vnd.dwg";
default:
return "application/octet-stream";
}
}
In my ASP.Net (2.0) Web Service implementation (The implementation class derives from
System.Web.Services.WebService with WebServiceBinding confirming to WsiProfiles.BasicProfile1_1 .
The SOAP response sent out by the Service has two elements missing :
1> The XML header itself : (<?xml version="1.0">)
2> The opening and closing Envelope tags with NameSpace ("<S:Envelope xmlns:S=http://schemas.xmlsoap.org/soap/envelope/>" and "</S:Envelope>" ).
This results in "breaking" of my client unless the above mentioned headers are inserted at the client end, and my intent is to avoid bypasses at the client end as far as popssible.Is this the default behavior ?
I have an asp.net appliction on the one server. There I've added code on server-side in Page_Load:
Response.AddHeader("key", "password-key-from-hotel");
On the client side I have a form:
<form ... action="www.link-to-another-domaint" >
<input type="hidden" id="asd" value="fgh" >
....
</form>
<script type="text/javascript">
document.forms[0].submit();
</script>
Then on the other domain - there is also my other application - I'm trying to get the hedaer "key" by this code:
Request.Headers["key"].ToString();
But there is no such header. Is there is a desicion? Where is my mistake?
've programmatically created a listview, for displaying images. When you click on the download the ItemCommand is fired, and the browser sends the user the image as a binary response, using the following:
SPFile ImageIfile = spfolder.Files[ServerName];
byte[] bs = ImageIfile.OpenBinary();
string res = Page.Response.ContentType;
Page.Response.ContentType = "image/jpeg";
Page.Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(fileName))
Page.Response.BinaryWrite(bs);
Page.Response.End();
This works, exactly once. Then neither the download link, nor the DataPage paging controls
work until you refresh (Indeed any postbacks).
EDIT: It's a SharePoint 2007 WebPart, this is the declaration of the ListView in the CreateChildControls method:
lv.ItemPlaceholderID = "itemPlaceholder";
lv.GroupPlaceholderID = "groupPlaceholder";
lv.ID = "MediaSearch";
lv.LayoutTemplate = new LayoutTemplate();
lv.GroupTemplate = new GroupTemplate();
lv.GroupItemCount = 4;
lv.ItemTemplate = new ItemTemplate();
lv.EmptyDataTemplate = this.Page.LoadTemplate("/usercontrols/MediaResults_Empty.ascx");
And this is the ItemTemplate and DataBinding
public class ItemTemplate : ITemplate
{
public void InstantiateIn(Control container)
{.....
Is there a way to get the raw response header and body from the HttpRequest.Response object for debugging when issues arrise?
View 4 RepliesI have a need to specify a custom response header from code when my web service is called. I know that from an ASPX page, you can easily modify response headers, but it is not so obvious from withing an ASMX page.
View 1 RepliesI am developing a web application which uses a third party Web service. It requires Username & Password in SOAP Header request. I am passing those credentials well and the web service returns an XML string in Response and also a SESSION ID in the SOAP Header.
I don't know how to read/access the soap header from the response sent from the web service.
I have the following code:
[WebMethod]
[SoapHeader("_webServiceAuth")]
public User GetUser(string username){
try
{
this._validationMethods.Validate(_webServiceAuth);
User user = new User(username);
[code]...
When I run the code below, nothing happens.
protected void Page_Load(object sender, EventArgs e)
{
System.IO.FileInfo file = new System.IO.FileInfo(Server.MapPath(Request.QueryString["path"].ToString()));
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "filename=" + file.Name);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.WriteFile(file.FullName);
Response.End();
}
The url of the page, is:
http://mysite.com/Lib/Rs/Download.aspx?path=/uploadedFiles/110210_CS_ADM-Coaching_SG_Final.pdf
If I add a param to the url and refresh, the file will load.
http://mysite.com/Lib/Rs/Download.aspx?path=/uploadedFiles/110210_CS_ADM-Coaching_SG_Final.pdf&ur=1223
Why wont the file load on the initial page load, or how do I get it to?
I am not able tto understand the differnce between REspose.Expire and Response.ExpiresAbsolute?
Is it mandatory to use both toghter?
So,I have this code:
[Code]...
Even though I have buffer set to false,no text is displayed.I have tried adding a response.flush,with and without changing the buffer value.What exactly is wrong?I've also tried it with and without the label(i.e. with or without just Response.Write)
I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:
[Code]....
This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?
I read this about the Response.Expires from the MSDN:"The Expires property specifies the duration of time before a page that is cached on a browser expires"what does the term "cached" stands for here?
View 5 RepliesMy problem today is that I am having trouble shifting some functionality, that is being used in multiple applications, from the applications themselves to a class library I have started building. The issue comes in the fact the code was written to utilize Response objects as seen below...
[Code]....
This is all currently within a function called "DownloadDocument". I continue to have issues running any of the Response object functionality. I usually get the error saying, "Response is not available in this context", is there anyway to use a Response object in a class library file?
Some of my users are getting the following error
HTTP 502 Proxy Error - The size of the response header is too large. Contact your ISA server administrator. (12216) Internet Security and Acceleration Server
I am guessing it has to do with the size of hidden "__ViewState" tag in my ASP.NET pages.
I also realize that this is restriction imposed to by IT on the users end and I have no contol over it.
I disabled ViewState on all the controls in my ASP.NET pages. However, __ViewState is still generated very large (as always) to persist control-state (e.g. checkbox, radiobutton, etc.)
What is actually meant by the request and response object in asp.net?
View 1 RepliesIs it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
View 5 RepliesI'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding
Here's the important stuff:
if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}
By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:
Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);
To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.
In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.
