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?
currently we are configured execution Timeout="1200" (The default is 110 seconds) and maxRequestLength="12288" (The default is 4096 KB)but some times users upload files above 12MB so we are getting "Maximum request length exceeded" error.we are checking the file size using client side javascript ActiveXObject object. but ActiveXObject only works in IE not in others like mozilla,crome,..Jacescript Code are

how can i check the file size before uploading process with support all the browser.any posiblities for checking file size before server side script/object?
when i upload a pdf file on button click it shows no of pages in that file on a label.if the file size is more than 4 mb then it shows ===
This webpage is not available
The connection to localhost was interrupted.
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.
View 1 RepliesUsers 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?

View 1 Repliesi 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

View 1 RepliesI 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.
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.

View 3 Replieswhile uploading the file on the local host it works fine.but the same coding does not work on the webserver. is there anything to do with the foldr read and write permissions.i m using the server.map for finding the path of the browsed file.
protected void btnLogin_Click(object sender, EventArgs e)
{
try
{
string fold = "images";
string Name = FileUpload1.FileName;
sring path = Server.MapPath("~" + "/" + fold + "/" + Name);

i hv not used any database for storing the path of the image.
I have a Web application in which I'm trying to use the new AJAX AsyncFileUpload control. I want to use it in the ModalPopupExtender, and I want to embed these two AJAX controls in a user control (photo_upload.ascx) for re-use in different parts of the application. (I understand that this wasn't possible with the older FileUpload control but that it is with this most recent AJAX tool.)
Presently, I merely redirect the user to an upload.aspx page that includes the photo_upload.ascx control (see the sequential screenshots in the attached image); but while this way of doing things "works," it becomes very confusing for the user who has already clicked an upload button or two. In other words, when the "Add Yours" button is clicked, the panel with the "(1) Upload Photo" button unhides; and when the Upload Photo button is then clicked, the user is redirected to the control in the bottom screen. I would gladly bypass the 1, 2, 3 steps in the second screen after the "Add Yours" button is clicked and redirect straightway to the upload control (in the bottom screen, which I will like to be in a ModalPopupExtender), but I also need a way for them to enter a caption that will go with the uploaded photo.

My VB code for the above steps is included below. I would appreciate any fresh ideas on how to accomplish my above objectives.

I've got a script below that uploads multiple files and works fine. I am trying to rename them as I upload them and I'm having some trouble figuring it out.
[Code]....
From this line
Path.GetFileName(hpf.FileName + "-" + recordID + "-" + i));
I am trying to rename the file with the record ID (from a querystring) and also the upload number of the file that is being uploaded (2 of 3 etc).
how can i achieve this?
Where can i find a good source to accomplish this? It needs to allow only excel or csv file uploads, which would be inserted into the database.
