.ashx Context.response.writefile - Use File On Remote Server?

Nov 27, 2010

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?

Javascript - Visually Format Remote Server XML Query Response?

Feb 9, 2011

I'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"> -->

[Code].....

Further information:

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.

C# - Can Retrieve Data From Server To Client During An Asynchronous Post - Back Using Ajax Library

Apr 9, 2010

ASP.NET Ajax Library provides some client-side events. For instance:

Sys.Application.add_load(
function(args) {
// handle the end of any asynchronous post-back. Every-time there's
// a server round-trip, this method will be called.
}
);

During the asynchronous post-back I want to retrieve information to the client. This information must be available in some event like the discribed above.

Does the UpdatePanel or the ScriptManager have any server-side way to retrieve data back to client during an asynchronous post-back?

Jquery Datatables Add Checkbox With Ajax Server Side Response?

Jun 18, 2010

I am using C# ASP .NET MVC and ajax calls. I am able to get the display of the table along with all features. But, I don't understand how do I add a checkbox and button. I have tried dom-checkbox as well but can't get it to work.

My code looks like this:

$(document).ready(function () {
$('#personTable').dataTable({
"bJQueryUI": true,
"sPaginationType": "full_numbers",
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "/Home/GetCustomData",
"aoColumns": [
{ "sSortDataType": "dom-checkbox", "sTitle": "Select",
sName": "" },
{ "sName": "ID", "sTitle": "ID" },
{ "sName": "FirstName", "sTitle": "First Name" },
{ "sName": "Email", "sTitle": "Email"}]
});
});

My Html is :

[table border="1" id="personTable" class="display"]
[/table]

AJAX :: How To Upload A File From Server To Client Without Attaching It To The Response

Mar 22, 2011

Basically I have to generate a rather large XPS document serverside and send this back to the client.

The issue I have whilst trying to do this is because the XPS document needs to be created on a STA thread, so either the response is sent back before the async operation is complete (in which case I can't attach the file using the transferfile method) OR I have to wait until the Async thread has completed and then I can send the file using the transferfile method (but this leaves the current page locked out for quite a while).

C# - Complete The Post Back After Writing Out A File To The Response?

Jan 28, 2011

I have a button that when clicked, will generate a PDF and write it out to the response.This is the basic structure of the code:

try
{
using(Stream stream = generatePdf())
{

[code]...

Downloading the file works fine, except that it doesn't complete the postback.If I were to throw an exception above file.Transmit, the error handling would work properly and I would see the message get displayed in my browser. However, if there is an exception after the file.Transmit then nothing happens. The user saves/opens the pdf and the page does not reload.How can I make it so that the postback always completes, that way I can display an appropriate message to the user?

Post Back Does Not Work After Writing Files To Response?

Feb 25, 2010

What I have?I have a ASP.NET page which allows the user to download file a on a button click. User can select the file he wants from a list of available files (RadioButtonList) and clicks on download button to download it. (I should not provide link for each file that can be downloaded - this is the requirement).What I want?I want the user to download multiple files one by one by selecting the required radio button and clicking on the button.What problem am I facing?I can download the file for the first time properly. But, after downloading, if I select some other file and click on the button to download it, click event of the button does not post back and the second file will not be downloaded.I use the follwoing code on the button click event:

protected void btnDownload_Click(object sender, EventArgs e)
{
string viewXml = exporter.Export();
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=views.cov");
Response.AddHeader("Content-Length", viewXml.Length.ToString());
Response.ContentType = "text/plain";
Response.Write(viewXml);
Response.End();
}

AJAX :: AsyncFileUpload - Server Response Error - Maximum Request Length Exceeded

May 6, 2010

When the user tries to upload a file with a size more than 4 MB, the AsyncFileUpload control gives a Confirmation alert (with "OK"/"Cancel" button) with the following message "Server Response error: Maximum Request Lengh Exceeded". But when the User clicks the "OK" button a new window popups and shows the server error and on clicking the cancel button the AsyncFileUpload background color turns red. Here I am not sure why the control is showing a Confirmation alert instead of a simple alert message. Is it possible to change the Confirmation alert with the simple alert message? Basically I don't want the popup window to show the server error as it is happening currently. Also, is there a better way to handle the file size error and show apporiate error message to the users?
