Web Forms :: FileUpload Validate File Size Before Upload Starts Not Working
Jul 5, 2010I do not want to change the default settings for file upload, 4Mb is more than enough for the project I'm working on. After quite a bit of searching I found two approaches that were purported to work but neither one is preventing the "Maximum request length exceeded" error. The first approach[see ref. #1 below] performs validation with a custom validator and in code behind on the page that contains the FileUpload control. It doesn't work. The second approach [see ref #2 below] performs validation in the Application_BeginRequest event in Global.asax. The author stated that validation must be handled by this event. Quoting: "The way to get past is to use your Application_BeginRequest event to handle the problem.. This event takes place for each request to your application BEFORE the data has been completely uploaded. Here you can check for the content length of the request and then redirect to the some error page or the same page with some value in session or query string so that the page can show appropriate message to the user." Here is my code from Golbal.asax based on the above. As noted, this approach doesn't work either.
protected void Application_BeginRequest(object sender, EventArgs e)
{
const int maxFileSize = 4 * 1000000; // Slightly less than 4Mb
if (Request.ContentLength > maxFileSize)
{
Response.Redirect("~/FileUploadError.aspx");
}
}
One comment by a reader of the Global.asax approach was that the value returned by Request.Content.Length would include everything on the page, i.e. viewstate, image and text content, etc. I suppose one work-around would be to set the limit higher in web.config but validate for max. file size in code behind, but that seems kind of silly because I'm manipulating the uploaded files (images) to reduce the size anyway; storage space isn't the issue, performance is. Has anyone managed to solve this poblem?

Web Forms :: Validation On File Upload Size?
Oct 18, 2010I have an application that lets the use upload a pdf, I wanted to put a limit on the size the pdf can be. If the user tried to upload something too big I wanted to display a message to the user. I am trying to use a custom validator where it checks the size of the file and if it is too big it will set the "IsValid" to false. Is this the correct way to go about doing this? Is there a better way? When I test it, everything works in IE 8 and FF, but it does not work in IE 7 and can't figure out why.Here is what I have so far, this is on my aspx page:

Web Forms :: Image Upload Control Which Strips The Size Before Uploading?
Nov 5, 2010i am working on an ecommerce application, user will be uploading several images of a product, instead of stripping the size (i.e the KB or MB size) after uploading it on the server, i want to strip the size of image before uploading it to the server ( bringing the size from any thing over 30KB down to 30KB) i.e on the client machine itself and then upload it to the server. i understand that this requires a download on the client machine which makes me ask the following questions :
a. can i use a java control in dotnet since java control can be used on all OSes
b. is there any dotnet control that might be userfriendly to all OSes

Feb 9, 2010I have to make an interface to upload large videos up to 30MB then stream and convert it into FLV format and then play it in a browser... this is required on my site in the "Video Gallery" module. My web application is in C# and ASP.NET. I can also use jQuery.
I have to send the video file in chunks then merge it at the server, stream it, create thumbnail for the video and then play it.
I found some code but it is all in PHP. I haven't found any C#, ASP.NET code.
Finally I got the code to upload the video file in chunks... like create its thumbnail and display the video in a browser.
Here is code to upload the video in chunks.
Upload button click

UploadVideoFile obj = new UploadVideoFile();
string FileName = fuUploadVideo.FileName;
