I'm using VirtualPathProvider and VirtualFile to send some Assembly Resource. The files are plain text files and I need to garantee that MIME "application/xml", "text/plain" or something like gets to the client Content-Type Response.Header.
I've tried setting:
[Code]....
But, still, "application/octet-stream" reaches the client side.
how to set ContentType on a VirtualPathProvider/VirtualFile scenario?
We are running ASP.NET MVC on IIS6. We have started to notice a problem with IE8 clients. Almost all the time, the ContentType returned is 'text/html' but occasionally, it will be returned as 'application/xhtml+xml'. This is causing IE8 to try and download the file instead of rendering the contents in the browsers.
Where is the ContentType set in the ASP.NET/MVC pipeline?
How do I set the contentType of an image I download?
I only need jpg, png and gif.
I want to set the contentType immediately after upload.
I would like to validate the .txt or .csv file that is uploaded using PostedFile.ContentType:
<asp:FileUpload ID="fileUpload" runat="server" Width="525px" />
Is "text/plain" the correct value?
if (fileUpload.PostedFile.ContentType != "text/plain") ...
Can we get the doc type and contenttype of a file from the filestream field?
View 2 RepliesSimple upload has been working for quite a while now, yet it seems to all the sudden not work (but only for specific file types). mp3 can upload, flv cannot (remember, this was all working before).After a little debugging, I discovered that a portion of my code is never being entered because I test something first:
[Code]....
I have discovered that resourceMediaFile.PostedFile is not null, resourceMediaFile.PostedFile.ContentLength is the correct size for the uploaded file, yet resourceMediaFile.PostedFile.ContentType is now null. I've literally had this work over 1,000 times with several files (including the one I'm testing with) and it consistently came back "application/flv".
What would cause ContentType to be null if the other attributes are not?
I am having a simple web service method which returns JSON serialized response. The attribute to web method is
[WebMethod, ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
As security of the return data is not a problem, I am Get enabling the HTTP response. On the client (browser) end, my code is as below
[Code]....
Everything works smoothly but occasionally on the web server's event viewer, I see the following error
"Request format is unrecognised for URL unexpectedly ending in /SomeWebServiceWebMethod"
After fiddling through the request headers using Fiddler, I figured out that if I make direct request to the webservice link, contentType header attribute is missing and that is what throws the error. There is a good post by scott guthrie explaining this. I am not able to replicate the issue and not sure what removes the contentType attribute from the request header occasionally.
I am using VB to upload image files to my server but am having problems. How can I use the ContentType to filter only image files? This is my code for my upload button which does not seem to be working. I can only upload bmp files:
[Code]....
Also, how can I show the user the image they uploade
how can i set Title for a page with Response.ContentType = "image/jpeg" ?
View 2 RepliesI've got an odd issue.I'm creating a DataTable type my application then converting it to a CSV so the user can download the data.
I set the content type like this:
context.Response.Clear();
context.Response.ContentType = "text/csv";
context.Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName + ".csv");
var responseBuilder = new StringBuilder(data.Rows.Count * data.Columns.Count * 30);
Now, this works well for all data sizes in my development environment, and for small amounts of data on my production environment, but when it gets to a larger size (say, more than about 4000 rows) on production Firefox gives me the error:
XML Parsing Error: no element found
I need to send an image (as a downloadable file) from an ASP web page. It is working correctly in every browser except for IE (all versions).
Here is the server side code:
bool export = Request.QueryString["Export"] != null;
if (export)
{
byte[] allBytes = File.ReadAllBytes(@"C:MyImage.tif");
Response.ContentType = "image/tiff";
Response.AddHeader("content-disposition", "attachment; filename="MyImage.tif"");
Response.OutputStream.Write(allBytes, 0, allBytes.Length);
Response.OutputStream.Flush();
Response.End();
return;
}
And here is the JavaScript:
$('#ExportFrame').attr('src', 'Default.aspx?Export=true'); // ExportFrame is an iframe
In IE, I keep getting an error saying "Internet Explorer cannot download Default.aspx from localhost". I thought it might be an issue with loading it in an iframe element, but redirecting to the URL is not working either. The really odd thing is that going to the URL (/Default.aspx?Export=true) does not work the first time, but works every time after that. Again, this works in every browser I've tried except IE.
Update:
The aspx page has the following code to keep the page from getting cached:
// Never cache this page
Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "no-cache");
Response.Expires = -1;
Removing the first 2 lines and leaving only Response.Expires = -1 resolved the issue.
This page contains the following errors:
error on line 1 at column 2: StartTag: invalid element name Below is a rendering of the page up to the first error.
Why am i getting this error in while browsing a page from dreamweaver? Here is my source code:
<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="utf-8" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">; <html xmlns="w3.org/1999/xhtml">; <head><link rel="stylesheet" type="text/css" href="test.css"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> </body> </html>
I am using the async file upload control to upload to a image file. I want the user to upload only jpg files. And for that I am checking the uploadedfile content type in server side, after the upload complets. I wanna check this, before upload starts. There is one javascript method
function startUpload(sender, args){}
but how to access the content type of the file selected by user.
I am getting this error on a website. does that mean the server is not competible with asp.net 3.5

Is there any way that I can make it so that to use a "Production" publish profile, it would require that the build configuration was set to Release?
I believe you're supposed to be able to customize the profiles with add-ons or something...?

I built my ASP.NET website using vs2008 professional.
Now I have purchased vs2010 professional edition.
I do format my computer and then installed vs2010.
Now I want to deploy my website in vs2010, but it is giving configuration error in <add assemblies...
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

We can retrieve configuration sections from web.config in the following two ways:
Configuration config = WebConfigurationManager.OpenWebConfiguration("/");
AuthenticationSection authSection = (AuthenticationSection)
config.GetSection(@"system.web/authentication");
[code]...
Web.config is the main settings and configuration file for an ASP.NET web application. The file is an XML document that defines configuration information regarding the web application. The web.config file contains information that control module loading, security configuration, session state configuration, and application language and compilation settings. Web.config files can also contain application specific items such as database connection strings
Example 1:
<!-- This is an example Web.config file -->
[Code]....
In this article, we will see how to read the configuration settings in the web.config using 'JavaScript'.
Step 1: Create a new ASP.NET website. Add a button control to the Default.aspx.
Step 2: Right click the project > Add New Item > Web Configuration File
Add the following sample entry to the appSettings section in the web.config between the <configuration> tag as shown in the example 1:
<add key="var1" value="SomeValue"/>
Step 3: To read these entries using JavaScript, add the following script in the <head> tag of your Default.aspx page as shown below:
<head runat="server">
<title></title>
<script type="text/javascript">
function ReadConfigSettings()
{
var v1 = '<%=ConfigurationManager.AppSettings["var1"].ToString() %>'
alert(v1);
}
</script>
</head>
Step 4: Call this function on a button click and display the values of the configuration settings
<input type="button" value="Get" onclick="ReadConfigSettings();" />
That's it. Run the application and click the button. The value of the key in the appSettings will be displayed in the alert window. I hope you liked this short article.

We are going develop a web application using asp.net. This applicaton is going to server 50 users per day and 40 users concurrently. As the user count is less, we are planning to have two webservers clustered under a webfarm. We are planning to go for a Sticky Session. Netscaler is the load balancing and reverse proxy we are using at hardware level to route to the same webserver till the end of the client session.
1. Do I need to implement any handler at asp.net level to route the session or to provide browser cookie details of session to NetScaler? If so, what should be implemented in detail. Any sample code will also be helpful.
2. I need to maintain a big chunk of object information in session. Does a webserver can handle it?
3. At the hardware level how ReverseProxy works to navigate it to the same webserver? I want conceptual details of it from a web application end.
