I'm using an .ashx handler to retrieve an image file... It queries a local database, which retrieves the URL of an image which is hosted on Amazon S3.
But I can't use context.response.write(AmazonS3URL) because it returns the error '...is not a virtual path'.
Can context.response.write only return files that are on the local machine? Or is there another function to call remote files?
I'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)
I have written simple HttpModule. context.Response.Output.Write is working fine. but not context.Response.Write().
View 2 RepliesIs is possible to write to the http response stream from a dynamically created bitmap using the Response.Write/WriteFile without saving the image to the hard drive?
View 4 RepliesI have a button that calls a click event to download a picture. In my click event I have some code to change my display as the Save dialog pops up. The issue I am having is that when the dialog comes up it stops the previous line of code from executing. How can I check to see that my code has executed before calling the function?

how to write two files using Response.WriteFile?
I tried the following
Response.AddHeader("Content-Disposition", "attachment; filename=" + textFile);
Response.Flush();
Response.WriteFile(FilePath);
Response.End();
streamWriter2.WriteLine(CodeFileText);
streamWriter2.Close();
Response.AddHeader("Content-Disposition", "attachment; filename=" + textFile2);
Response.Flush();
Response.WriteFile(FilePath2);
Response.End();
But it downloads the first and stops.
It doesnot go for second one.
Response.ContentType = "pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=test.pdf");
Response.WriteFile(this.txtFileName, true);
Response.Flush();
Response.End();
which shows a prompt to download the file and the prompt by default has "Open", "Save" and "Cancel" buttons with "Cancel" selected by default.Is it possible for me to hide the "Open" button and force users to eitehr save or cancel?
I've made a user control with several LinkButtons on it. On click of any of these buttons executing following code:
Response.ContentType = "Response.ContentType";
Response.AddHeader("Content-Disposition", "filename=" + CorrectFileName);
Response.WriteFile(filename);
Response.End();
And I have to problems with it:
1. after user click on one of the buttons another ones doesn't response
2. I need to execute some code after user received file (delete copy of it from the server)
I suppose I need to open another window and call SaveFile dialog from it. But how can exactly do this? I've found example code of opening window or starting SaveFile dialog but not two of them together and I can't figure out how to put them together...
I have an asp.net page.
Which is used to download files from server.
The page is using Response.WriteFile method to start download.
Every thing is working fine.
But download does not have resume support.
if I redirect user to that file without using Response.WriteFile method then it supports resume.
I've just installed VS 2010 RC and IIS7 with .NET framework 4.0 on a Windows 7 laptop (and I'm very new to this).
I'm trying to use Response.WriteFile to add a menu to an .aspx page, and it works but it also adds two square/unknown characters before the inserted text. Also, when I view the source of the displayed webpage in IE8, the source gets up to the point of the two squares, then shows an opening angle bracket (<) and then stops, although the rest of the webpage displays fine.
It doesn't matter whether the included file has any text in it or not, or whether it is an .html or .aspx file.
Response.Write doesn't have the problem.
(In FF and Opera, the inserted text is displayed as html code with a space (opera) or unknown character (FF) between each normal character. I'm not worried about those browsers as I'm developing soley for IE8)
I'm using a custom ashx handler to handle a file upload. When run locally, the file uploads fine.When I use the same setup on the web server I get a "Index out of range" error.In firebug I see the binary contents of the file in the post data and the file name is also passed in the query string.Any one seen this before?I`m sure its something minor, but its driving me up the wall.

AJAX is under the same origin policy. Is there a clean way to use ajax to post data to a remote .aspx page and get response ?
View 2 RepliesI'll preface this by stating I am a rank amateur when it comes to web dev.
I have a web appliance that provides XML data when issued a query string such as:
[URL]
I created a simple form that allows users to modify values of this query and have the appropriate XML returned. Here is that form:
<form id= "report" action="https://mysite.com/api/reporting.ns?" name="report">
Username: <input name="username"><br />
Password: <input type="password" name="password"><br />
<input type="hidden" name="generate_report" value="SupportSession">
Start Date: <input name="start_date">
<input type="hidden" name="duration" value="0">
<input type="hidden" name="limit" value="all">
<input type="submit" value="Show Report">
What I have not been able to accomplish is formatting that XML response so it looks pretty.
I have created an XSLT that formats the XML nicely and have used javascript to transform the XML using the XSLT like this:
function loadXMLDoc(dname)
{
if (window.XMLHttpRequest)
{
xhttp=new XMLHttpRequest();
}
else
{
xhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET",dname,false);
xhttp.send("");
return xhttp.responseXML;
}
function displayResult()
{
xml=loadXMLDoc("Report.xml");
xsl=loadXMLDoc("Report.xsl");
// code for IE
if (window.ActiveXObject)
{
ex=xml.transformNode(xsl);
document.getElementById("content").innerHTML=ex;
}
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation && document.implementation.createDocument)
{
xsltProcessor=new XSLTProcessor();
xsltProcessor.importStylesheet(xsl);
resultDocument = xsltProcessor.transformToFragment(xml,document);
document.getElementById("content").appendChild(resultDocument);
}
}
Which works locally but I run up against the cross domain security problem as the web appliance is hardened and I am not able to place any code on it.
I have been searching this site and the web for a couple days looking for a method to accomplish this using other means [asp?] and have been largely unsuccessful. The main reason this is so is that I don't know asp so I'm not sure how to attack it.
I think creating the query string in a form, then loading the resulting xml response from the web appliance to a string and applying the XSLT that resides on the server to it might be an option but haven't been able to make it work; again because I'm not really sure what I'm doing.
Here is my XSLT:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<div class="contentBox"> -->

I found a way in asp to retrieve remote xml that works for URL's like http://site.com/file.xml but doesnt work for my URL. Maybe because it is a query? I've looked at way to encode/encapsulate my URL but haven't found anything that works.

"Unable to connect to the remote server" on line :

Note: I was able to connect to both of these ftp through filezilla, via a webbrowser, and through windows command line.
I have deployed my site in Win 2003 server. In this, it copies file from Another server and copies it in local. It is working with my local computer, but not in the server i have deployed. I hope access credentials may be the first reason. But are there any other reasons for this.

My Question is can we extend one context to another in Entity Framework 4. Following is the problem background.
I am using EF4 for developing a Web-Application. My Web Application has 3 projects.
One project is for storing candidate CV information.
Another project is for storing customer information.
Final project is called CORE. this CORE contains a edmx file that should be extended by CV and CRM.
As an example email address table can be shared by both customer (CRM) and CV. To share one table with another, we should be able to extend one context (CV context) with other context (customer context). Could some one having experience using Entity Framework share your experience with me to find whether this is possible.
We have 3 edmx files in three class libraries:
Person class library(Core) with core.edmx-Basic details related to a person(name, email) CV Class library with CV.edmx wich have CV related data(Experiance,skills) Customer Relationship management system(CRM) which have customer data(sales data...)
Then we want to use core class library edmx file(Core.edmx) with cv.edmx (basically cv tables should be able to use tables from core tables) . Same way we want to use the core.edmx with CRM.edmx for the 3 rd project
I have configured my web application session timeout to 30 mnts and kept the code
Response.Redirect("Login.aspx")
in the Session End. But when ever my session is ending its giving exception "HttpException was unhandled by user code, Response is not available in this context.".
The below code works fine for downloading a file from a current pc.plz suggest me how to download it from remote server using ip address or any method
protected void Button1_Click(object sender, EventArgs e)
{
const string fName = @"C:ITFSPDFbillsFebruaryAA.pdf";
FileInfo fi = new FileInfo(fName);
long sz = fi.Length;
Response.ClearContent();
Response.ContentType = MimeType(Path.GetExtension(fName));
Response.AddHeader("Content-Disposition", string.Format("attachment; filename = {0}", System.IO.Path.GetFileName(fName)));
Response.AddHeader("Content-Length", sz.ToString("F0"));
Response.TransmitFile(fName);
Response.End();
}
public static string MimeType(string Extension)
{
string mime = "application/octetstream";
if (string.IsNullOrEmpty(Extension))
return mime;
string ext = Extension.ToLower();
Microsoft.Win32.RegistryKey rk = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
if (rk != null && rk.GetValue("Content Type") != null)
mime = rk.GetValue("Content Type").ToString();
return mime;
}
When my asp.net aspx page unloads i am trying to check if the current session is expired. I have this code in the Page_unlaod and i get a "Response is not available in this context" error. What is the problem placing this code in the Page_unlaod?
[Code]....
the page is in a frame with 3 other pages so when the page is doing a postback, there is client side code that will the page 2 in the frameset to 100% visible, then when page is laoded and the document is ready it sets itself 100% visible in the frame. I have tried placing the code in page_load but when the session has timedout the pageload is never executed again. I have tried to place the code in the pageload of page 2 in the frameset but that causes some funny behavior and unwanted redirects.
filetoread = Server.MapPath("\servernamesharefile.csv")
filestream = File.OpenText(filetoread)
readcontents = filestream.ReadToEnd()
It works fine if I put the file in the local directory and use "filetoread = Server.MapPath("file.csv")", but won't do it over the UNC path.I'm guessing the problem is security related but can't find any info related to it, do I need to somehow specify a username/password somewhere ?
I have many images on remote server say [URL] & i want to access file names of all files that resides in the folder 222 on [URL]
i have tried following code but getting error "virtual path is not valid" :

DirectoryInfo di = new DirectoryInfo(imageserver); // line giving exception
FileInfo[] rgFiles = di.GetFiles();
string simagename = "";
if (rgFiles.Count() > 0)
{
foreach (FileInfo fi in rgFiles)
{
//collect each filename from here
}
