I'm currently looking to replace the in-built "DirectoryListingModule" in IIS 7.5 with a custom version to make the listing a little prettier. The problem is I cannot seem to find anything on the subject of writing a managed module to do this myself. I've read the IIS 7 module/handler tutorials over on Microsoft's site, which are helpful albeit very basic. I've also seen Mike Volodarsky's implementation but unfortunately no source code is provided. The only other resources I can find link back to either Volodarsky's blog or the Microsoft page (which is also written by Volodarsky!). I guess what I'm saying is I don't know how to get from the basic module in the Microsoft tutorial to the directory listing functionality of Volodarsky's example.
If anyone can provide a hint on how to tackle this I'd be very grateful. Also please let me know if any of this isn't clear (I'm terrible at writing).
Thanks in advance :)
Edit - Just to be clear, I realise I have a lot of reading to do and am not looking for anyone to do my work for me.
Mike Volodarsky's implementation is really simple:
you create a module that intercepts requests to "directory" urls within your application.
This module will create a collection of object that rappresents directory structure and save it in the httpcontext
Then you load an aspx page which binds to the httpcontext saved content.
I don't get what you are asking for?
If you are not able to develop that module you can use the Mike Volodarsky's one and just customize the aspx page...
The PreRequestHandlerExecute event in an ASP.NET Application is where you can process and replace the default IIS handlers.
You have two option:
Use the Application_PreRequestHandlerExecute event in the Global.asax file.
Write a custom IHttpModule and use the OnPreRequestHandlerExecute event.
Regardless of which method you prefer to use, you must ensure that the request is a directory not a file, other registered handler, and so on.
Use the below code to check for it:
if (!Directory.Exists(context.Request.PhysicalPath))
return;

I need to change some styling on my webpage based on if it's being called from one website it's embedded in vs the other (as an iframe). I looked up a bunch of stuff about it; uri, requests, httprequests, using the "object sender", but nothing seemed to show any differences. I am trying to do this inside the "Site.Master.cs" in asp.net. Any help or tips are appreciated, thanks!
I think what you're looking for is HttpContext.Request object. Has lots of properties about the requestor,
specifically HttpContext.Request.UrlReferrer,HttpContext.Request.UserAgent, HttpContext.Request.UserHostAddress and HttpContext.Request.UserHostName

I'm trying to generate an xml sitemap for published Umbraco content. Ideally I'd like to access UmbracoHelper.TypedContentAtRoot() or something similar that gives easy access to published items. I need to access it outside the web solution, inside a supporting assembly where I'm generating xml sitemaps and sitemap index for dynamic content outside the direct control of Umbraco.
Any ideas about the easiest way to go about this? I've tried referencing various Umbraco assemblies and digging into what's readily available but haven't found anything immediately useful yet.
I have stumbled across
UmbracoContext.Current.Application.Services.ContentService.GetRootContent()
but this seems to require a much deeper understanding about how Umbraco content works under the covers in order to drill down to extract published content for me to index.
Can anyone point me in the right direction? Thanks in advance!
Assuming the DLL you are creating is going to be using IN the umbraco site, you will be able to access UmbracoContent.Current in your classes, as long as you've got a reference to the Umbraco.Core package, as Mivaweb states.
If on the other hand you want to access the UmbracoContext from a completely unrelated external application (say an executable file), then that it MUCH harder to do. A few people have got it sort of working, but it's a bit flakey. Usually in this case, you're better off adding some kind of WebAPI controller action that you can call via HTTP from your executable file, so you have full access to Umbraco on the site.
Update:
If you just want to access the typed content, you can get at it by using:
UmbracoContext.Current.ContentCache
This will allow you to do stuff like:
UmbracoContext.Current.ContentCache.GetAtRoot();
Which will get you all of the root content of the cache.
If you have a seperated project where you would like to do Umbraco stuff then go to the nuget package manager and install Umbraco.Core.
This will install only the necessary Umbraco dll's that you then can use.
Then you just need to include the namespace and you are ready to go.
I'm trying to create a wpf application such as a movies library because i would like to manage and sort out my movies with a pretty interface.
I'd like to create a library with all my movies getting information from the web, but i don't know how very well.
I thought to get the information from a web site, for example imdb, but i don't know if it's legally to capture html from page to get the nested information.
It's my first desktop application and I would also like to know if it is necessary to create a database within the project and then create a setup project with specified script for deploy it.
Sorry for the confusion but i would like to know too much things :)
Thanks a lot in advance.
The legality of web scraping is a grey area. See my question, "Legality of Web Scraping vs Normal Use" and the corresponding answers for some insight.
Even if the legality is not a problem, web scraping is a flimsy approach because the webpage structure may change without notice, making your application suddenly useless until you update it to the new format. You are much better off using some sort of web API (if the site providing the information offers it).
Whether you need a database or not depends entirely on what your application will be doing and how you design it - it's not something any of us can tell you.
Same goes for the setup project - in fact I wouldn't worry about that until you actually have a working application. Take it step by step and keep the scope within control.
Yes I did not think about api.
It's a great idea, maybe use "themoviedb".
But if i create an application based on it, that has to show all the movies that you have stored on your hdd and get , for example, the posters, the description and the ranking, i have to create a database according to you?
Thanks a lot.
I'm trying to implement a drag-n-drop fileupload to my website and found a piece of java called Dropzone.js, it holds everything i need . . . i just have no idea of how to use it!
So far I've been programming only in razor ASP.NET (c#) / HTML / CSS, but so far no javascript / jquery.
It's razor webpages, so no mvc.
Due to my current lack of knowledge in java, i apologize in advance but i'm stuck !!
What i'd like to know is:
I'f i've understood things correct, i should not modify Dropzone.js directly, i should use it as a library and integrate it in my other scripts, e.g. in another .js file. Correct?
Any help in this will be greatly appreciated.
Kind regards,
Daniel A. Rischel
.. Edited as per requested.
Well, you're wrong somewhat. It might not be related to the question but please note these scripts are JavaScript and
java != javascript
Got the point? :) Please try to note this in future. Also, Java code cannot be added to these server-side language, because java itself is a language. You can use JavaScript or its library (jQuery) and create some plugins.
I'f i've understood things correct, i should not modify Dropzone.js directly, i should use it as a library and integrate it in my other scripts, e.g. in another .js file. Correct?
True, you need to link this plugin dropzone.js to the site using
<script href="/link/to/dropzone.js"></script>
Then you'll use this script on the whole of the page where it is linked.
And you should never edit the source code of a plugin, untill or unless you know what you're doing. Because you might mess up with the code.
I'd really like to see some source code examples of what a single file drag-n-drop fileupload form would look like. I've googled extensively but not found something i can use yet.
Did you try to read their documentations? They have a good code explaination on the default (main) page of their website too. And really it depends on just the way you style it. Its just a plugin, you will need to add your own CSS code to style the form. This plugin won't style the form for you, all it will do is to handle the upload events and get back with the result. So, which means that form creation and elements is all upto you!
If there is a dummies tutorial in making this work, i'd really like to be pointed in the right direction!
There is no perfect answer to provide you with, however I will provide you with some basics
http://www.javascriptoo.com/dropzone-js
https://stackoverflow.com/questions/tagged/dropzone.js?sort=newest&pageSize=15 (stackoverflow tag)
In the second link, you can go and see what are the very basic of the issues that are handled with what code. Easy methods will be hanlded by you! You'll need some guidance in just the hard jobs. Good luck for that!
My suggestion for you is to first undertand and learn jQuery, then learn how to make ajax calls. After that you'll know how to create and handle the events. The basic code will be
$('input[type=file]').change(function () { // change in value
// send the file via ajax
}
http://jquery.com
This method will be best as you will know what code you're using and what it will do. Using plugin is easy method then this one. But my preference is with the second one; creating your own plugin.
I have an web based application. The content for the Home page has been currently mentioned in the HTML code for the Home page using , and tags. To change the content anytime in future, it needs to be changed in the HTML code. :(
Is there a way that we can pick up the content from some external place and get it reflected through the website. This ways, any change if required can be made at the external location without referring to the application's code.
Please advise if there is any solution for it.
Thanks.
You can
Use a database
Include external files using Server Side Includes
Read external files and write their contents and an alternative method
Sounds like you're looking for a Content Management System (CMS), which will allow your content editors access to modify only specific blocks of a page that you specify.
There are a ton out there to do what you want, so you don't have to start from scratch. Just Google 'CMS'.
Although I haven't used it myself, DotNetNuke is a popular one these days and has a free version.
