Web Forms :: Finding Client File Size Before Uploading?
Sep 28, 2010
I need to upload images from client to server as follows:
1. Server is passing the client a file name
2. Client is checking file extensins to ensure it's an image then issues a __dopostback to the server.
3. Server uses the FileUpload control to save the image on the server.
I have that all covered, but, if image is too large, the upload fails with the following error: 'System.Web.HttpException: Maximum request length exceeded.'
Is there a way to check file size on the client (without the use of ActievX which also errors out), before it is passed back to the server?

With the ajax file uploader, would it be possible to check the size of the image before uploading?Currently, it uploads the file to the server and then lets me know that it's bigger than the limit size.

I have figured out that javascript cannot obtain the filesize of a to-be-uploaded file because it is a security risk and it is not allowed access to the clients HD. But I want to see if it is possible to get the file size before uploading the file, perhaps using AJAX.
So by looking at the requests, when you click the submit button on a form that contains a input type=file, the Request actually has the filesize inside of it, so you could therefore get the first request, cancel the request there, and send the file-size data back to the client without actually uploading the file.
I want to do this via AJAX so that it doesn't post back and also without clicking the submit button. It seems impossible to create a submit request with javascript because there is no way to get the file size. But is there a way to fake a submit? How does the submit button get the information? Is there any documentation on how the submit button actually works?

I have written a website and let the user upload their photo. It also resizes the picture to 400 x 400 and crops automatically to the center part of the picture. All of this works good but each file is about 355K each for JPG and PNG file formats. I just tried GIF and it is 49K but the picture is grainy when saved this way. Is there any way I can get the picture to a smaller file size with keeping it at 400 x 400? I really thought PNG would be the way to go and was surprised by it being the same as jpg. I don't want to lower the quality either for JPG files.

My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

Users of my C# web application can upload images. I have configured the max upload size in the web.config file to maxRequestLength="1024" and executionTimeout="180".
How can I check the upload size before uploading? (do you have examlpe or url?)
Another option might be to check the dimensions?...
Some web application allow the user to crop the image at client side. Do you have an example of this or url?

i 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

I am using a sql server 2008 database and I am uploading images to the server using an asp.net webapplication. I have an image column that I use to store the images. I have chosen the database to store the image and not a folder on the server, because the database table will contain only very few rows. maybe close to 10 or 15 rows.
My question is, Do I have to reduce the size (dimensions and quality affecting size on disc in kbs) of the image in code behind before uploading it to the database or do I keep it as is. The total upload size permitted is 200kb. I am thinking that when the image size (size in kbs) is small my webapplication performance will not be affected when displaying them from the database.

In uploading files and determining their length, I want to know if there is any alternative to
<code>
file1.PostedFile.ContentLength
</code>
It seems that this quantity is counted up as the actual uploading is taking place.
Once the customer has selected his file-to-be-uploaded and put it in the textbox, is there any
other way for my script immediately to say "This file is 5 Mb and it is therefore too big" ?

Is there such a thing as an optimum chunk size for processing large files? I have an upload service (WCF) which is used to accept file uploads ranging from several hundred megabytes.
I've experimented with 4KB, 8KB through to 1MB chunk sizes. Bigger chunk sizes is good for performance (faster processing) but it comes at the cost of memory.
So, is there way to work out the optimum chunk size at the moment of uploading files. How would one go about doing such calculations? Would it be a combination of available memory and the client, CPU and network bandwidth which determines the optimum size?
EDIT: Probably should mention that the client app will be in silverlight.

I am Developing a mid-size application and want to implement Application Architecture, I've read some Architecture Books and Approach and think about
AAFN (Application Arcitecture For .net) presented by Microsoft
SOA
SDLM
SDO
MVC
and vice versa ...
this is a web application that will extended with some other small application ( just think about something like a M.I.S with a (or two) core)
Whitch Projects I should have I think about
Common // to use in all projects
Framework // main framework
DAO // data access object ( entityframework or nHibernate )
UI // will available in 2 variant web and windows(wpf) interface )
BusinessEntities // all subApplication project logic will goes there
ApplicationNameProject // each application have their Own Logic (in BussinessEntities)
ApplicationUnit // each application Entity will place here
ApplicationNameProject // each application data Entity (in Application Unit)
Services // WCF Services goes here to contribute with all applications
this is the architecture witch I think about, I do not have any force to use this, I want to know whats the best fit for me, can Change all of it or add some other projects and remove these projects

Without reading the whole text below, since this is on the ASP.Net side ... basically I think I need to know if there is a way to reduce the size of the forms authentication cookie. When using a DotNet 2.0 website, the ASPXAUTH cookie is about 232 bytes ... when using the same source code but upgraded to DotNet 4.0. the cookie is approximately 264 bytes, setting the ticketCompatabilityMode does not reduce the size since I think the default setting is Framework20. I length of the cookie, including the its' name can not be larger than 256 bytes in order to use it with the "Client Application Services".
I only did a cursory search of the asp.net forums, but will dilligently look for an existing solution.
----- BACKGROUND AND RESEARCH -----
I have been using all three features of client application services (authentication, profiles, and roles) in my windows app (DotNet 3.5 framework) for almost two years now. Up until now, I have not had any problems. This week I hit a brick wall and am pretty stumped with two seperate but related issues.
Issues:
In development, we decided to upgrade our websites/services to DotNet 4.0. All applications upgraded successfully. However we are unable to log into our application using Client Application services. No matter what user we use, Membership.ValidateUser returns false. Since we know the username and passwords, we thought this was strange. When debugging the application, we found that Membership.ValidateUser was throwing an InvalidOperationException (see below for complete exception) stating that the ASPXAUTH property was too long, longer that the schema created in the SQL/CE database. (See below for things tried).
In production .. A user all of the sudden could no longer gain access to the application. Upon inspection, his ASPXAUTH cookie was 264 characters long (9 characters longer than the schemas nvarchar(256)). Even though the user was being authenticated on the "server side", and the JSON query returned "{"d":true}", Membership.ValidateUser returned false. Again, as in the case above, the actual error was ...
Message=@PropValue : String truncation: max=256, len=264 ...
I am assuming I am missing something very simple or that I overlooked a settings. In development, this is not a huge issue as I can release the Dotnet 4.0 websites when I am ready. But now that this has happened to a client on a production system, it is very worrisome.
