View 2 RepliesWe 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 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:

Also, how can I show the user the image they uploade
<form id="form1" runat="server"> <div id="dvforimage"> <asp:TextBox ID="Txtimage" runat="server"></asp:TextBox> <b>This is text</b> <img id="imgforconvert" src="images.jpg" alt="img1" /> </div> <asp:Button ID="btnforimage" runat="server" Height="28px" Width="72px" Text="ok" onclick="btnforimage_Click" /> </form>
I want to convert all data present in div to jpeg.I mean image,text or whatever i write inside div tag.You have given me previous cod e which only convert text to image.
i am developing an application usinf ASP.NET 3.5 with C#.
in my application i have to display the image in Title pf ASP.NET page.My application has master pages and content pages.The image is in Images folder which is there in my application.
How to display the image in master page and content pages
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.

View 1 RepliesI need to write a routine which uploads a largish (2-4 meg) jpg photo and shrink it down to a small size. Adobe image ready does what I need but I need to develop it in my web application. Basically I need to reduce the image file size so it is web friendly.
View 9 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 be able to export PDF's that I am creating to JPEG, so that users can have a screenshot/thumbnail of the end product, which is faster than opening the whole PDF.
I am running this on an ASP.NET website running in Medium Trust in the Rackspace Mosso Cloud.
I have yet to find a library that will either work in Medium trust, or in the case of ABC PDF, which works great locally, wont load in Mosso. Maybe Mosso has a custom trust level?
I know that iTextSharp works on Mosso, but I haven't been able to figure how to "screenshot" a single page of a PDF, or export a page to JPEG.

Every time I create a new aspx page and add some new photos and text, after I finish, I have to update page title, Web.sitemap, Sitemap.xml to feed search engines, static sitemap.aspx page, add photos to proper folders, update database to display feeds etc, and I have to remember to upload all new files including links to any new pdfs....This routine eats my time and drives me crazy.
I was wondering if there is such interface, where you need to create only 1 aspx page, for example "Articles" which can populate Texts, photos etc into pre-defined sections, but at the same time it displays with different URL's, so there is a permanent link to it. After you finish it creates a title automatically, based on article title, populates Web.sitemap - does all the dirty work. Similar to how blog engines, Joomla and Drupal work.
