I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?

View 3 RepliesMy website is allowing the web.config file to be downloaded. However in my C:WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGweb.config file I have this line
<add
path="*.config" verb="*" type="System.Web.HttpForbiddenHandler" validate="true"/>
Which should mean any config file can't be downloaded.
When I have a HttpHandler class in C#/ASP.NET mapped to a file extension in IIS any file with that extension fails to download/display in web browsers (it's downloaded as a 0-byte file in some browsers and nothing at all in other browsers). After removing the application mapping for the HttpHandler in IIS so it doesn't call the IHttpHandler class in C#, the web browser downloads the file successfully.
This was tested with an IHttpHandler class in C# that has an empty ProcessRequest method.

I'm having a heck of a time getting an image to display from a SQL database. When I view the source of the page in Firefox and then click on the link in the source for the image control, I see the following message:

I have 50 sites for 50 states. When a company uploads their contact info their image is stored in a folder relative to the site they are uploading from. When you view this company on the other sites the image is not present. So, I was thinking I would store the path of where the file is originally and then access it through the handler, but I can't seem to get the handler to recognize locations other than virtual directories.

a silverlight app sends an image to a webservice which store the image in a database and then a handler retrieves the image from the db to display it... quite common so far.
Everything is working absolutely fine on my test server (IIS on my development machine) but, as soon as i try it on the production server : no way, the image is never displaying (in any browser). Firefox says that it cannot display it because it contains error...
I tried to download the database from the production server just after saving an image to the db and, locally, the image is displaying...
The image is in png format.
Here is my code :

I use http handler for loading images.
View 1 RepliesI had a Handler to display User's Image by UserId. it worked when I debug in Microsoft Visual Studio 2010, But when I published to the web server the Image did not display. I also used Microsoft Visual Studio 2010 to debug from the the Directory on the web server, it worked too. But when I tried it through browser it doesn't work.

Environment: IE7, ASP.NET 3.5 SP1, C#, IIS 7, intranet, SQL server 2008 R2 enterprise. I'm trying to implement a page with 3 pictures in it (each picture is up to 1MB, jpg format), and switch them with the next 3 each 250 milliseconds. I thought of several methods for implementation:
1. Store all the pictures in a virtual folder, then switching the src attribute of img html element by javascript, and manipulate caching by storing the next 9 pictures also as img element, but with display:none for css.
2. Store the images in a database table and than send it to the client using DIME (don't know how to do it yet).
3. Store the images in a database table and use custom http handler to retrieve the picture (don't know how to do it yet).
4. Client invocation of webservice? Which of the above results the best performance? Is there another method for caching pictures?
I am working with ihttphandler.It works well in IE,Opera,FireFox. But,in chrome the image is not shown.

and on the other page I would like to retrieve the database image using :

In my project there is webhandler to create image and display it in all pages of site like below.
<img id="imgpro" runat="server" ImageUrl="/images/imagedisplay.ashx?ID=<%#Eval("ID") %>&Table=ProductPhotos&Thumbnail=true&DefaultImage=true" AlternateText="<%#Eval("Name") %>" />

how can i create thumbnail from that image in particular page in which webhandler called.
