I am unable to show images in CR reports. I'm developing a MVC 2 project in VS 2008 with Crystal Reports that comes with it (10.5). Everything works fine, except for images. I can see them in the preview mode within the CR designer, but not when the app is deployed, which means I am loading data OK but something's wrong with IIS and/or routing.
When running the app, images appear with the red cross and if I navigate to the following url directly I get a 404 error.
http://localhost:1234/CrystalImageHandler.aspx
I think my problem is similar to the one here but that workaround doesn't seem to work for me.
I should also comment that I'm using the Areas feature within MVC.
EDIT: Forgot to add: When exporting the report to PDF the images are shown ok.
I don't know much about crystal reports, but is there an Http Handler? If there is and you are running IIS 7 on the live server, is the handler registered in the web.config under both system.web/httpHandlers and under system.webServer/handlers?
I forget to register the handlers under system.webServer/handlers for our IIS 7 server sometimes and we were having a similar issue with the Microsoft Charting Controls.

Umbraco 7.6.6, running under IIS 8.5 on fully patched Windows Server 2011 R2 Standard, 64bit.
Our content editors notice that often when they create a new article (which has some graphics specified) the system hangs after they try to browse to a different article... or indeed anywhere in the front-end site, too. It only affects them; other users are still able to browse and/or create content.
F12 dev tools shows that browser is pending the result of this type of call:
http://whatever.com/media/1101/thumbnail_pmc-1x2.jpg?width=500&mode=max&animationprocessmode=first
If I try to view that thumbnail without the querystring data, it loads instantly... while the first call is still hanging in it's unresponsive tab:
http://whatever.com/media/1101/thumbnail_pmc-1x2.jpg
DEBUG level Umbraco logs just show this:
2017-10-10 17:02:53,120 [P2816/D6/T57] DEBUG Umbraco.Web.UmbracoModule - Begin request: http://whatever.com/media/1101/thumbnail_pmc-1x2.jpg?width=500&mode=max&animationprocessmode=first.
No errors in the umbraco logs, no errors in IIS logs, nothing in event viewer.
Best I can tell, something is going wonky in the browser. Can anybody please advise on how I can troubleshoot further?
Thanks!
I have a web app with asp.net mvc 5 on running on iis 7.5. I have a photo upload page that I made with DropZone (a javascript ajax upload plugin). In my asp.net controller during certain errors, I return an httpstatuscode of 500 with a status description with a descriptive error. DropZone then displays this descriptive error. Everything works as it should on desktop devices, however when used on an iOS device it displays a generic "Internal Server Error" message.
I'm lost at how to troubleshoot this issue. I've placed javascript alerts throughout my javascript code to try and figure out what the issue is but that didn't reveal anything helpful. I've tried using the MIHTool ipad app and the HttpWatchBasic ipad app to try and set breakpoints but that was not helpful either.
Is there a way to remotely debug an asp.net web app from an iPad? (I have visual studio 2013 premium) Or does anyone have any ideas what may be causing a different status code to be sent?
UPDATE: It appears that iOS devices ignore any custom xhr.statusText and uses the standard default statusText (i.e. code 500 is Internal Server Error). As a work around (which I hate doing, but since this is primarily for use on company iPads I didn't have much choice) I've returned a different 500 class code for each possible exception and then in the javascript code check the status code and assign my own custom error message in the javascript code.
Quickest and easiest way to see the actual exception is to turn off custom errors in your Web.config - you'll then be able to view the actual stacktrace on the iPad.
If you'd like to be able to debug the exception, you should be able to trigger it by accessing the site from the iPad by hitting your windows development machine while running in the debugger. You'll need to configure IIS express to allow remote connections (editing application host.config), adding a urlacl, and opening the Windows firewall if necessary. There are numerous guides in setting this up online.
If you want to actually debug the JS in mobile Safari, this is possible from the Mac version of Safari - see http://webdesign.tutsplus.com/articles/quick-tip-using-web-inspector-to-debug-mobile-safari--webdesign-8787 for details.
I have an app that takes a screenshot of web pages and creates a resized image. The app is basically loading a web page that calls an ActiveX to load a web page using IE resources and take the screenshot. This app has been running on a Windows Server 2003 without any problems for a couple of years.
But now that I have upgraded the server to Windows Server 2008, the screenshot action is timing out. From tests I can see that it successfully takes a screenshot of any web page hosted on the Internet... except pages hosted on the same server.
Whenever it tries to capture a page loaded on a site hosted on the same server as the app, it times out. ESC is disabled and it seems that all other permissions are ok, ie: it works for remote pages but for home pages.
Any ideas as to what can be causing this and how to fix it?
After further testing I have narrowed down the reason for failure being due to the page being popluated from a MS-SQL database record on the same server as the one taking the screenshot. The same page generated on a remote server captures ok. I have further established that the error is not peculiar to the ACASystems DLL because it also affects another DLL for creating MHT files from web pages. This DLL (Chilkat.MHT) also uses IE to load and assemble the web page on the fly and then saves it as a.mht file.
So the problem is more related to IE assembling web pages from MS-SQL while running ActiveX. But to resolve this enigma?
Maybe a routing issue (DNS/hostfile..) ? Does the page loads on local session with IE ?
There is no solution for this without editing the ActiveX code. Since the DLLs in question are third party resources, such editing is not possible.
After testing 3 different ActiveX that load a web page that either take a screenshot or save as .mht, it was found that they all failed when loading a page that was querying SQL on the same server. After contacting the 3 DLL developers we were informed by all of them that their ActiveX has no impact on MS-SQL.
Unfortunately, our tests tell us otherwise. At this stage we are left guessing however this article about in-process vs out-process execution may be related.
The workaround for us to solve this problem was to assemble the page to be captured from request queries passed to the page rather than populate from SQL queries. This alternate works perfectly.
I want to get away from developing in PHP but doing that is proving to be a massive headache.
I am trying to set up a website with MVC 4, ASP.NET 4.0, on Win7 Professional (64-bit). The website is just the basic site that is set up with Visual Web Developer 2010 Express selecting New Project > C# > Website > ASP.NET MVC 4 Application.
After setting up the application in IIS7.5 I am getting an HTTP Error 403.14 - Forbidden. I've done a ton of research and tried multiple different suggestions on how to solve the problem but NOTHING is working. Here are some things I tried:
Install/Register v4 of ASP.NET. This has been the most annoying
thing because everyone else's issue is fixed when they do this but
mine is not.
Changing the application pool settings:
Set to classic/integrated mode
Change the user/permissions used by the application pool
Made sure 32-bit applications were enabled
Added security permissions to folders related to the website (on multiple accounts)
I can get a regular html document to show up if I add it to the websites root directory. It seems that the MVC stack is not being called at all. The server wants to display the directory, which I can enable/disable, but the website is not being displayed.
Please can I have more potential fixes before I resort to my last desperate act? A baseball bat.
p.s. I'm more than willing to do a skype conversation or a share screen kind of thing if someone wants to dig in deep. I am beyond frustrated with this.
So it seems, in my indefinite well of stupidity, I was pointing the webserver to the incorrect folder. I needed to point the webserver to the folder with actual files of the application rather than the folder containing the .SLN file. Sorry to waste your time!

I have reading posts all night looking for an answer to my issue and haven't found anything that works for me yet. I am sure there is a simple way to do this but I haven't been able to discover it yet.
Details:
MVC 2 Preview
Asp.net 3.5 sp1 framework
VS 2008 C# web application
Windows Server 2008
IIS 7
I have the application running well through VS 2008 no problem. When I hit the play to run in debug mode it starts the ASP.NET Development Server the application loads fine and works as expected, great!
When I publish the application locally or to my web server both on IIS 7 the application doesn't run correctly. Some of the icons are missing and the google maps map is missing. When I view the source it appears correct at first glance, but I can see the paths to the images are looking for the MVC paths and it isn't finding them. It appears the app is running as a regular asp.net app and not an mvc app, maybe?
I also tried to just hit the full source code locally on localhost and the exact same issue is present.
So, I guess my question is how do I deploy a MVC application to run the same in IIS as it does through the development server.
PS The environments are clean and pretty much out of the box.
#user68137 is correct in saying that you need to use relative paths for the images.
I got caught out on this one too, and here's my previous SO question about it...
In short, you need to do something like this...
<img src='<%= Url.Content( "~/Content/Images/banner.jpg" ) %>' alt="Banner" />
Hope this helps!
I had the relative paths set, but what I didn't realize is when I deployed it to the server it went to wwwroot\subsite... I had the relative paths set to src="....\image.jpg" to get back to the root of the site. My error was that if the site is not in the root then the subsite drills back to the root to find the images and of course doesn't find them. Same thing was happening with the JS files. I used the Url.Content and it worked great! problem solved!
The interesting this is when running through the VS dev server with a subsite it still worked well and found the paths even though it shouldn't have. VS dev server <> IIS
Thanks for your help on this!

Once you know the virtual path to the location you are deploying the project to, you should go into the project configuration in Visual Studio and add it to your project. This way the visual studio development server will use the same path structure as the deployment server. This will save you countless hours of work when deploying.
When you run your website through Visual Studio, every single request gets processed through the ASP.NET pipeline, including images, CSS and other resources. IIS by default only processes specific extensions (e.g., aspx) unless you tell it otherwise through configuration. Paths like '/content/images/yourimage.jpg' should work just fine...I suspect it's something amiss in your IIS configuration.
Another possibility which I've run into is any custom ISAPI filters you may have installed on the IIS server (e.g., ISAPI_rewrite). It's easy to set up rules in its configuration that lead to some very unexpected results.
