How To Upload More Than One Large Images At Same Time
Jun 28, 2010
internet Explorer cannot display the webpage when trying to upload a large image.I have a webform for inserting images. There are four FileUpload controls on the page, allowing the user to upload 4 images at the same time. It inserts them directly into database, in Image field, but before that I am resizing them to 200px x 160 px.
The problem I am having is as follows: If I try to upload larger images (over 2MB), one at the time, everything goes fine. But if I try to upload 2 or more larger images at the same time, I get the message: Internet Explorer cannot display the webpage, and there is a button below: Diagnose Connection Problems.
Can you please point me to what could be an issue? It obviously has something to do with the image size, but I have no idea what.
how to upload images to server(application/images folder) and retrive(display) from and on client PC for asp.net. its just for uplaoding logo directly to server folder and retriving from server to client. i am not getting server path on client pc for image.
I'm looking for a way to have user upload as many images as they want (perhaps via drag and drop) or dynamically adding more upload box.I thought statically fixing (say 6) HTML upload input box is slightly limiting and the user have to click "Browse" button (6 times in this example) and navigating to the folder to pick the file.What is the best practice to achieve this so users find it easy to use? Perhaps with some AJAX magic?I also wouldn't mind having the user click "Upload more" to reveal (say 6 more) HTML upload input box.
im trying to implement a gallery of sorts where the usercan view and upload images (he can only upload once signed in). Does anyone know where i can find a gallery like this, or do i have to code it myself?
What is better way to large upload file.using a web service or in application itself.If in application, how can we check that files is to upload in a regular interval.actually i dont want user to wait for complete uploading, when it starts uploading user will get response of uploaded and uploading will be done in backgroud.I am not sure this type of task can be done in webservice also so that user doesnot need to wait for complete uploading.and one more query which event fires when the page redirects to another page.Is it Page_UnLoad or Dispose
We use the MojoPortal to a website and have some problems to upload files that is around 100 MB with the upload module. (Pleas note that this has probably nothing to do with MojoPortal but with the ASP.NET and the IIS)
The MojoPortal is set to use regular file Upload(not Neat Uploader) and to be able to upload big files we have set the following :
The problem is that the upload will cacel after a couple of minuts (Aborted).
Is there any other values that I need to set to make this possible? The MojoPortal itself should not have any settings for this as far as I know so its regular ASP.NET 4.0.
Anyone got some good pointers at an open source (article for creating your own would even be better) component to upload large files.SlickUpload for instance works great, and surely worth the money, but as this is for a pet project, a paid solution is just not what I'm after.
I am trying to upload file in WCF.When I try to upload file I am getting following error message. System.ServiceModel.CommunicationException:The socket connection was aborted.
I am building a website where i need a page where user can upload large video files, i have created WCF service with streaming but i am calling that WCF service from Button_Click event of web page.
I have used below mentioned article for WCF service creation
WCF Streaming
I have used streaming as it should be efficient and should not be buffered in memory of server.
Now questions
1) I am having doubts that the entire file is uploaded to the web server and then it is transferred to WCF Service server...if this is true then i am not getting advantage of streaming as well as iis and web server will be down very soon if user uploads large file or multiple user are uploading files con currently
2) Is there any other efficient way to do same operation with some other technique
EDIT :
If I am not calling WCF Service method from ASP .Net code in that case also it is transferring bytes to the web server which i have checked with HTTPFox
I have checked above thing with upload control and putting one button on UI whose click event is bound to one method in code behind.
So, still i am having that confusion that how data is transferred
Client Machine - Web Server (ASP .Net Application) - Service Server (WCF Service) Client Machine - Service Server (WCF Service)
NOTE : If i am putting a debug point on button_click and uploading 10 kb file it hits that in less then 1 sec. but if i am uploading 50 mb file then it is taking time.
I placed code of calling WCF service inside that button_click event
I need to create an upload site to upload large files over 2GB I want ot create a site like [URL]. Once these files get upload i want them to have a link to the file created but the link encrypted. I know there is a limit to http upload. I have used a bunch of the flash upload web apps but are capped at a specfic mb becuase of .net. What options are out there.
I have a scenario which I am looking at where large files which are about 30-40 MB are being FTPed to a server. I am looking at creating a .net screen with the FTP control to upload the file to a Unix server. I need to know how much of a performance hit it is to work with such large files, is it a feasible option in this scenario? I might have to create a .net component for the same and call from ASP application. Is it doable?
We'd like to restrict the maximum upload file size in our web site. We've already set the appropriate limits in our web.config. The problem we're encountering is if a really large file (1 GB, for example) is uploaded, the entire file is uploaded before a server-side error is generated, and the type of the error is different whether the file is huge or not. Is there a way to detect the size of a pending file upload before the actual upload takes place?
Here's my relevant web.config settings that restrict requests to 16 MB:
[Code]....
Update:
I know that client-side technologies like Flash can detect file sizes before upload, but we need a server-side workaround because we're wanting to target platforms that have no Flash/Java/ActiveX/Silverlight support. I believe that IIS or ASP.NET has a bug that's allowing large files to be uploaded despite the limits, so I've filed a bug here.
Would an ISAPI extension give me more control over request processing than HTTP modules and handlers, such as allowing me to abort an upload if the Content-Length header is seen to be larger than the allowed limit?
Update 2:
Sigh. Microsoft has closed the bug I filed as a duplicate but has provided no additional information. Hopefully they didn't just drop the ball on this.
I have standard asp.net file upload control on a page. If a user try to upload large file they get all the cryptic error messages like page not found etc.I dont want them to be able to upload large files, but still want to show gracefull error message saying that file is too large to upload or something like that. Is there any way to do that?
I am trying to figure out a solution to upload large files under a web page. I know WCF + Streaming is a proper solution for large file transfers, but I am not sure how to get the WCF client implemented under ASP.NET. Here is the link: [URL] Besides, is there anyway I could implement a progress bar showing the upload progress while the file is being uploaded, and voiding page timeout?
i have a large excel file which has 1 lakh row , i want to insert these data in my table i am using entity framework for insert but it takes more than 45 minutes to insert which is too much, i want to speed up the uploading process what should i do. can I use multithreading for it if yes then how i can use? if any other way to do this process.
