I 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.
Here is the Handler:

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.

The image is missing from the webpage generated.
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 want to download images from third-party server. for that third-party provide url link for each page.
samples are provideded below.

when click on each link it will give an image in browser window.
i want to store each image automatic in server.
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.

I wrote a generic handler like this:
[Code]....
and on the other page I would like to retrieve the database image using :
<img alt="" src="ShowImage.ashx?ID=467711" />
but I am getting nothing in this case. The picture exists and there are 91000 bytes in array.
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.
GetProductData return correct image url but in my ashx page it doesn't appear.
List<ProductItem> p = ProductFactory.GetProductData(); foreach (ProductItem c in p) { rss.WriteStartElement("item"); rss.WriteElementString("title", c.Page_Title); rss.WriteElementString("link",

I am bulding a site that will create word documents from templates and fill in the bookmarks. Its working fine when running locally in VS but when I publish to the webserver it seems to have an issue opening word. Durning testing I created a new site that only has the code below and its still not working - you click on a button and it looks to have worked but word never opens. I have done 2 days of fault finding to no avail. The server has office 2003 installed and I have put the correct dlls in the bin folder of the project and still no joy - I have played around with as many settings as I can in IIS and still nothing.

View 3 RepliesI've read different posts on both of these issues and maybe I'm just not understanding what needs to be done. Here is my dilimma. I am running Windows Vista with IIS 6 and coding in VS 2010 using .NET 4 for the ASP.NET site. I installed the AjaxControlToolkit.NET4 in VS 2010 with no issues. I even used the TabContainer and had no problems on my machine, at least when debugging. When I publish it out and install on my remote Webserver 2008 with IIS6, I get the following errors:
Webpage error details
Message: ASP.NET Ajax client-side framework failed to load.

I can't see the tab container...Likewise My reports (using reportviewer) on local machine are displaying perfectly but on my webserver they are not showing...
