MVC Alongside WebForms With Custom HttpHandlers?
Dec 20, 2010
I am researching phasing MVC into our WebForms site. The caveat is that we already have our own SEO mechanism for mapping/rewriting URLs via an httpHandler. So in the web.config:
[Code]....
Now my existing URL mapping code is not called, so a request like "http://mySite/sally/admin.aspx" throws a 404 when it should be rewriting the URL as "http://mySite/admin.aspx?userId=2". I found that all is well until I call routes.MapRoute...it seems that is the point where MVC takes over for all requests, even though I have code to explicitly ignore requests for "*.aspx".

I created tables in my database for managing a user's profile.I have the user table (username, password, passwordSalt, etc.) report (1 to 1) with a table ProfiloUser (idprofilouser, iduser, name, sex, DoB, email, etc.), the latter table reports (1 to 1) with the table ProfiloAzienda (idprofilouser, idprofiloutente)
and finally I have another table that is related profilodestinazioni (1 to many) with the table profilouser.
how I can create a custom profile is on web.config, which side code.I've created this in web.config:

I have a very simple query. I have added custom header to my website. Now I want to read the custom header. I am using IIS 6.0 on windows XP. I have already tried using using the Request.ServerVariables and and Request.header method. But none of them give me the custom header added to website.

I'm trying to secure my web application so XML files it contains can't be downloaded. I thought it would be as simple as adding these to the "httpHandlers" section of web.config:
<remove verb="*" path="*.xml"/>
<add verb="*" path="*.xml" type="System.Web.HttpForbiddenHandler"/>
This failed - the XML files could still be downloaded easily. I tried different browsers in case they were caching, but everything could download the XML files without any trouble. I thought this might be due to some special handling of XML, so I tried mocking up an alternative based on ".txt123" files. I added this file with some dummy content:

We have a handler to deal with .dat files.. everything is already setup and server is acknowledging the file type and doing its thing to handle it..
But the handler requires 1 bit of information along with the HTTP request which is a physical file path.. the file name it knows based on the file we call , but how can i pass a custom header along with the request so that the handler will use that when the request is made?
Basically when on our player.aspx page, i will have a button, when you click that button a request is made to the .dat file, but along with that request i need to send the physical file path.. how can i do that?

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'm looking to implement my own basic webforms authentication. I don't want to use the 'membership' features in this case because I don't want to modify the database schema with all the membership elements that I won't use, and I don't need to support users across multiple applications. I want to wind up with one simple 'users' table that has username, password, passwordSalt, and several other fields to support custom user attributes specific to this application.
I was looking at this:
http://www.xoc.net/works/tips/forms-authentication.asp
but it's rather dated... is this still valid? I'm looking for guidance on what I need to do to implement a custom webforms auth solution. A very basic skeleton I can expand upon, or a good tutorial/guide that illustrates the necessary parts... just the basics..

I'd like to create a custom datasource that is shared between a Winforms and Webforms project. This functions as a middle layer for a reporting tool(DevExpress Reporting). The Webforms project is a designer for these reports. So we want for the reports to be capable of going to the server to get data and such. So our datasource would abstract away all the communication overhead. Then, for consistency, the datasource would also run on the server for reporting, except for their would be no communication.
What would be the best course of action? There doesn't seem to be such a thing as a DataSource in Winforms. Is DataSource not the thing I'm looking for?
Edit: After some research, it appears that IDataAdapter may be good for my purpose. Any opinion on that?

i have a custom handler which captures user's book mark entry. To debug this handler, i have created a file "test1.txt" in code behind which saves the user entry. After the debug, i removed the text file (test1.txt) then re-complied the web app and deployed new DLLs for the site. But, the site is still looking for test1.txt file. i dont know how to confirm if the handler is really removed from the new DLL. Also, looked at the handler code behind file and didn't find any entry with test1.txt. So,

I am writing a custom HTTP module to implement user authentication and appropriate access rights. And for identifying access rights for the user also depends on identifying the client's machine details like IP address, machine name, etc. The access rights will depend based on from which location or machine the user is trying to login.
Can we get these details from the HttpApplication or HttpContext object?

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)Code is as follows.

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.

Is there a preferred way to configure an ASP.net solution so that OpenRasta can run alongside an existing application asp.net application.
I'm interested in what the process would be for a request coming in to the server for:
a resource OR knew about
a resource the old web app knew about
a resource neither app know how to handle
I'd like to keep the 2 projects separated so that we can gradually move over functionality to being based on OpenRasta and away from our legacy app.
As an example, on a machine with a virtual directory of /api
Requests to /api/contacts <-- handled by OpenRasta.
Requests to /api/v0.1/contacts <-- handled by Legacy web app.
Requests to /api/junk <-- handled by Neither web app.

I am updating a project I wrote some time ago. At the time my preference was for DataSets and DataSetTableAdapters, but I've now moved on to use Linq to SQL DataClasses. I would like to convert the project to Linq to SQL, but I am tight on time and it's a big job. My question is, is there any reasons I can't develop new modules using Linq to SQL DataClasses along side DataSets and convert the DataSets overtime?
Apart from the obvious confusion it will cause, are there any technical problems I should be aware of i.e. will there be any performance problems using the two methods?

I'm currently using Validation controls to validate a form. I tried adding a separate onclientclick javascript method to do some extra validation but it now appears to only run this and not continue on to run through the Validation controls. The extra javascript method is returning true, so I'm not sure if the onclientclick is clobbering the scripts from the Validation controls. Can anyone explain what I've done wrong?

I have a datagrid which pulls data from a single database table to display it. However, this database table also contains information on the thumbnail URL for each record, and I would like to display the thumbnails for each record in the 1st column of the datagrid.
At present I have added the following to my datagrid:

So I presume the main challenge now is to set the Thumbnail.ImageUrl property to the correct file path in the VB.NET code. But how do I do this for each record? I am using a function to retrieve data for the gridview, which is based on the following:

I'm writing an ASP.NET MVC site where I need to have a "Tasks" application that runs alongside the website. Such a "Tasks" application would collect data at set intervals and insert it into the database.
Of course, I could write a simple Console Application and use the Windows Task Scheduler to run it, but my site is being hosted by GoDaddy and I only have medium trust permissions.
Are there any methods for implementing such functionality while not violating medium trust permissions?
One method that I'm considering is a method in the site itself that gathers data, waits for a long time, and then gathers data again. Would that interupt users' connection to the site?

I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:

I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.

I need to get an image from a SQL Server as a byte[], and load it to a WebControl.Image. The only seemingly good way to do it that I found is to implement IHttpHandler and handle the request accordingly.But I'm stuck to using asp.net 1.1. Does it support ashx files?
