How To Specify Metadata Location In Connection String When Using An Edmx File
Jan 29, 2010I have a web project with a data model defined in an edmx file. The connection string starts like this:
metadata=res://*/;
This has worked fine for a while. But somebody else working on the project created a dll that also uses the entity framework and added it to the bin folder. Now when I try to create my connection there is an error loading the metadata.
Aside from totally changing the way one or both of us is doing things, I wonder if the problem can be fixed if my connection string can be changed to only look for the metadata defined in my edmx file. The problem is, for the life of me I can't find the right syntax to do this. The metadata is embedded in the output assembly, so there are no physical metadata files to point to. How exactly should I specify the metadata location in the connection string?

View 1 RepliesMVC :: Extend The HtmlHelper By Using Metadata / Access Metadata In HtmlHelper Extension Method?
Jan 9, 2010I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

Mar 24, 2011I've configured progressive video player on my website. When I'm passing direct url to .mp4 file everything works fine.
when I'm trying to pass file bytes from my .ashx file. Player begins to play but if you try to seek it'll write buffering, buffer video till the seekpoint and continue to play.
here is my file download script in .ashx handler
FileStream sourceFile = new FileStream(FileName, FileMode.Open); long FileSize; FileSize = sourceFile.Length; byte[] buffer = new byte[(int)FileSize]; sourceFile.Read(buffer, 0, (int)sourceFile.Length); sourceFile.Close(); context.Response.AddHeader("Content-Disposition", "attachment;filename=file.mp4"); context.Response.ContentType = "application/octet-stream"; context.Response.BinaryWrite(buffer);
Web Forms :: Browser Hangs On File (video) Streaming?
May 4, 2010I'm having a problem with file streaming where this file is a video that is streamed to a FLV player.
Essential components for understanding the problem:
- An asp.net page called Viewer.aspx that has de FLV player incorporated in the HTML.
- An asp.net page (It could be an http handler but in this case it's not) called Downloader.aspx that gets a flv file from somewhere on the web and writes it to the Response Output Stream.
Everytime Viewer.aspx is called, it makes Downloader.aspx the source of the the FLV player and the video is correclty presented and streamed into the player.
The problem I am having now is that any user interaction with the page (even typing an URL inside the same website domain on the browser address bar) becames hung until the video download ends.
I can measure this video download with HTTP Watch for example, and confirm that just after the video download into the player ends, the command issued by the user is immediately processed (or the browser goes to another page if the user typed a new address in the browser address bar).
I tought that it could be the limit of 2 connections per domain, but HTTP Watch only shows one active connection (the video download into the FLV player).
Even if it was this 2 connections limit, I think a nice solution would be to somewhat detect the user interaction with the page and abort that video download.

how to retrieve this file information in ASP.NET? I am building an upload page and want to retrieve more information than just the basic file-name, file extension etc info. I am coding in VB. It is written into the file itself so it must be possible to access this information somehow. However, my search efforts so far have not got me very far...

Feb 23, 2011I have a form that will accept and save a MP4 video file. I need to be able to get the dimensions of the video as well. This will be running on a server running ASP.NET 2.0 so any external libs must be able to be placed in the Bin folder as they can not be installed on the server.
how to get the information? If the same lib would let me transcode the video to flv that would be a huge bonus.
Update: The server is XP Service Pack 2 with .NET Framework (2,0,50727,0)
