HttpHandlers / Modules :: Create A Thumbnail Of The Image Which Uses WebHandler?
Jan 18, 2010
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") %>" />
Now I want to create a thumbnail from image which will create from above line code.
i don't want to change the code for webhandler because it will reflect in all other pages.
how can i create thumbnail from that image in particular page in which webhandler called.

I have a website running on IIS7 in integrated mode (framework 4). I have added a <handler> to deal with page requests.
my web.config
[Code]....
my dll
[Code]....
When i run site.aspx in my browser, it loads for about 20 seconds, and then I get "Connection was reset" / "Webpage cannot be displayed". Google Chrome returns "Error 101 (net::ERR_CONNECTION_RESET): Unknown error".
It works well in the VS2010 development webserver. It works on IIS if the handler is an appcode cs file, but as soon as I move to a DLL, i get this error. After attempting to load the page a few times, the app pool crashes and has to be restarted.

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:
The image "view-source:[URL] cannot be displayed, because it contains errors.
Here are the details:
The column holding the image is an "image" data type.

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 :

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?

[Code]....
and on the other page I would like to retrieve the database image using :
<img alt="" src="ShowImage.ashx?ID=467711" />

I'm going to use aspx pages as templates for code-generator. I found two ways how to achieve it, but with both have troubles.
Test project consists of two files code.cs and test.aspx with only "Hello!" text.
[Code]....
1. GenerateA with GetDomainForGenerator failed with "This method cannot be called during the application's pre-start initialization stage."
in the out.txt and stack trace
[Code]....
2. GenerateB with copy-pasted CreateWorkerAppDomainWithHost from cassini source generates correct out.txt
But when I put smth related to my assembly in test.aspx (for ex.:<%@ Page Language="C#" %> <%@ Import Namespace="TestHost" %> Hello!)
the result is "Compilation Error" and the everything is good when import for example System.
I dislike both of listed approcahes.
The first is due to magic values in dom.SetData and the second one due to magic System.Web.Compilation.BuildManagerHost
and I don't know what is happaning in background.
So, how to create and configure AppDomain and Host?
Where can I read about background process of HttpRuntime?

I am wanting to create a url rewriting module and have investigated numerous examples on the web. However, most do not address the issues of handling postbacks and querystrings. I cam across a few examples, but don't fully understand how they work and thus customizing them to my needs becomes a problem. I understand the basic concepts of rewriting, but can someone explain, or point me to a resource on how postbacks and querystrings are handled?
