1. Start a new class library project in VS 2010
2. Add System.Web and System.Web.Mvc assemblies to the project
3. Implement Class1 as follows:
[Code]....
4. When you try to compile you will get these errors:
error CS0115: 'ClassLibrary1.Class1.WriteFile(System.Web.HttpResponseBase)': no suitable method found to override
error CS0534: 'ClassLibrary1.Class1' does not implement inherited abstract member 'System.Web.Mvc.FileResult.WriteFile(System.Web.HttpResponseBase)'
Notes:
1. This only happens in VS 2010. Works fine in VS 2008.
2. I tried it on two different machines with the same result.
I wanted to use the ASP.NET Chart Controls, but since all of the available examples used a code-behind page reminiscent of Web Forms, I shied away from this. Then I found an example returning the Chart Control as a FileResult, and tried it out. It worked, I was happy and all was good in the world. Except that occasionally I'll get a broken link showing instead of the image it should resolve to.
Here's how I have it set up:
In the View, the code is very simple. It's just an image tag that has its src attribute set to the Controller method. I didn't realize this was possible, and thought it pretty cool:
[Code]....
In the Controller, I instantiate and build the Chart Control in its entirety, and then output it as a FileResult:
[Code]....
Yes, it's a bit long and involves, but that's what you get when programmatically building something inititally set up to be a server control. All of this works, and even when I get the output that shows a broken link, if I refresh the page, it generally fixes itself. Here's the code from the FileResult created for this purpose - it's not a Controller, but I placed it in with the Controllers just while testing:
[Code]....
I'm thinking that the reason behind the occasional broken link is related to the DataContext object, not any of the above code. It seems reasonable that if the DataContext doesn't build and return a FileResult quickly enough, perhaps because it's doing too many other things, the broken link would show because no file had been built where it was expected. I've included the code anyway, in case someone can find an issue that would cause the problems I've been encountering. Any advice would be greatly appreciated. I had this working with Flex chart components that I genericized so that they worked with MVC methods, but they were way too slow to complete rendering. It often took 3-7 seconds, which was just too long for a user to wait for their page to load. These Chart Controls are really fast and are a perfect solution - if I can get them to render consistently.
I'm having problems with FileResult returning a file with a specific filename. In the database the filename is just and ID + extension (e.g: 456789.mp3)
Work well in every browser except Webkit browsers (Chrome, Safari). Chrome and Safari receive files as original filename (456789.mp3). When I add headers with
Safari receives the file as myfile.mp3attach (notice "attach" appended to the extension?), however Chrome receives this file as myfile.mp3,attach (it appends ",attach" to the extension)
how page update methods are normally done in a web page with multiple sections? I have a few web pages containing several sections. Each section contains different controls/values and can be saved/updated at any point. Can this be done without creating multiple save functions for each "save" button click in each section? Can this be done with one save class that accepts any number of different values?
Also, i have some page values that should insert if it does not exist and update if the value already exist. Currently, i have to check the database to see if the value exist before inserting and updating. Is there a better way of doing this in VS 2010?
I'm trying to implement a media player on my web page using Visual Studio 2010 and it's 'toolkit'.
In the toolbox i right click on general->Choose Item->Com Components and select Windows Media player.
But nothing is happening.
If I right click on the general tab and press 'Show All' both the windows media player accor but the icon are like 'invisible' and you can't drag it into the design window.
A second question, if I want to use a different media player, how does I do that? I.e. VLC...
I have a clean installation of Windows 7 with VS2010 RTM and am trying to get the ASP.NET Development Server to work. When I run the project, the WebDev server starts and shows that it's listening on port x on localhost. I've tried:telnet to the port. The port is not listening. running netstat -o shows that the WebDev server is in fact not listening on any port. manually changing the WebDev port to a different port and restarted VS without effect. I have Windows Firewall turned off entirely and am not running any other firewall software either.
I've wrote the comprehensive post within my blog: [URL] In brief words everything is simple:
1. I've downloaded free Visual Studio C# 2010 Express and Visual Studio Web Developer 2010 Express 2. I've successfully installed these versions. 3. I've tried registration online - and got the appropriate keys which I've used for registration.
Finally all the keys I've got are not valid for the system - and after 30 days evaluation (for free version?) period all these products are not running anymore because all the keys I am providing from online registration are invalid.
I have been ising TFS 2010 with VS 2010 Ultimately for a couple of months now. I have a client who is using Visual Web 2010, does anyone know if this integrated with TFS easily?

I have a piece of code which loads either french or english text and 2 link buttons that allow to switch between.
[code]....
What would be an efficient way of displaying the link buttons and text if both English and French exist and the session exists in either EN or FR.
I've thought of using panels to hide the buttons or text, but the main problem is having the page refresh to set the Session variable. Response.redirect(URL) to refresh the page i suppose and i can't find a better way to display the text other than to Response.write it since then i'd need a ton of labels.
