I have this concern that I never found out an answer to. If people are on a page on the site that are processing something on that page and at the same time I upload class and/or aspx and .vb page to the server while they are still processing, what happens? Will their data get corrupt? will they be using whatever was there before the new upload until they refresh their page? how does it work?

I wanted to know how to prevent more than one user from uploading the report at a time .
This is a Windos based app written in c# . When User A clicks Upload option on one server from the menu to upload the files and at the same time when User B clicks Upload option on different server , User B should be alerted a message saying "User A's uploading is in progress,pls wait" . How to achieve this, with the code..I am thinking this logic should be kept in a stored proc, How do I write that proc?
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 am using a file uploader to upload files. Now when i am using this on a mobile emulator with default browser IE it is uploading only those files whose name is less than 6 character. the files with name more than 6 character is not uploading through mobile emulator or mobile phone (PDA). I need this solution very soon.

I've dug around in the SDK and managed to connect to my instance of S3, go into my bucket and create an empty file, but can't figure out how to take a file from my computer and upload it. If I have dragged a file upload control onto the designer surface how do I set the properties for it in the code behind?(If I absolutely need to have a 3rd party uploader which should I use). Here is the code I have so far.
static string bucketName = "myBucket";
static string keyName = "sampleKey";
static AmazonS3 client;
protected void Page_Load(object sender, EventArgs e)
{
string accessKeyID = System.Configuration.ConfigurationManager.AppSettings["AWSAccessKey"];
string secretAccessKeyID = System.Configuration.ConfigurationManager.AppSettings["AWSSecretKey"];
using (client = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID))
{
// simple object put
PutObjectRequest request = new PutObjectRequest();
request.WithContentBody("this is a test")
.WithBucketName(bucketName)
.WithKey(keyName);
S3Response response = client.PutObject(request);
response.Dispose();
// put a more complex object with some metadata and http headers.
PutObjectRequest titledRequest = new PutObjectRequest();
titledRequest.WithMetaData("title", "the title")
.WithContentBody("this object has a title")
.WithBucketName(bucketName)
.WithKey(keyName);
using (S3Response responseWithMetadata = client.PutObject(request))
{
WebHeaderCollection headers = response.Headers;
foreach (string key in headers.Keys)
{
Console.WriteLine("Response Header: {0}, Value: {1}", key, headers.Get(key));
}
}
}
}
On a web page, I need to allow users to input the path to a file (on shares on servers) - which will be stored in a database so I can subsequently display 'a list of documents that apply to this project'.If I put an input type="file" on the page, it makes it easy for the user to browse to the document ... but, when the form is submitted, the document will be uploaded to the server. I don't want the document, I just want the path.
How would you provide the functionality to allow a user to browse to a file so that you could record the path to the file without actually uploading the file itself?I just want to end up showing, on a web page, a list of files like:
myserverfolder20somefoldersomefile.doc
myserver2folder50somefoldersomefile2.doc
I need to give users an easy way to locate those files in the first place - without having to laboriously open Windows Explorer, find the file, and copy and paste the path. A file upload control gives you access to the path - which is what I need - but I don't want the file uploadedIf I do end up using a file upload control - I don't want to save the file on server - how can I dispose of it so I don't end up with hundreds of temp files?
I'm rather new to the topic of designing web applications, and during my attempts to create something i stumbled upon a rather tricky question. For my application I want to do a user control with which user will be able to select a file from a hard drive and upload details about this file. I dont want the user to send the whole file, just the details about it. For example lets say user selects a mp3 file. I dont want the whole song to be uploaded but i want the details about that song like the Author, on Album etc. Is something like this possible without uploading the whole file?
I tried looking up that topic on the internet but i found nothing... though i dont believe I am the first one with such a dilema;]
I'm completely new to web design and am looking to add the programming functionality to back the form I've created for my website, so hopefully someone can point me in the right direction.
I have a form that has both data and file fields and I need to be able to have the form contents transferred to a file on my server. I want the contents of the form to be accessible only to me when I access my server.
I don't really understand how ASP.net works but was hoping someone could either offer me the proper script or point me to a novice-level tutorial that will explain what I need to do.

How to upload a file(any format) into DB columns by changing it into binary format??What data type should we use for it?
View 15 RepliesI am uploading files using HttpWebRequest to an ASP.Net MVC application but, for some reason unknown to me, it is failing to upload consistently.
I know the file is good since if you try enough times it does eventually upload and can be viewed on the server just fine. When it fails, neither the server nor client reports any errors directly related to the upload, the upload just stops partway through at a random location and time and my MVC action method is called without the file being loaded (Request.Files.Count == 0).
This only seems to be a problem in our production environment over DSL. The test and development environment works fine and the production environment works fine from in the office (really fast connection to servers) but fails when running it from home over DSL.
As you can see below, the point where it fails is basic.

View 1 Repliesi ve deployed many applications with file uploading feature on dedicated server and never got any issue. but it is not working on shared sever :( .. i think Server.MapPath("~") is not working on shared server. as in shared sever i am unable to find those directories which must for uploading.
m using following code for creating directories
string RootLocation = Server.MapPath("~") + "\";
string siteUploads = RootLocation + "uploads" + "\";
Directory.CreateDirectory(siteUploads );
i am working on a project in which I want user to upload files on to my website so for that i created a folder in which i'll store all those stuffs.now the thing is that it is all working fine on localhost but when i use it on server ,,it provides an error which is
Access to the path 'C:inetpubvhostsebas.co.inhttpdocsuploadsfile.exe' is denied.
i think this probably has something to do with the access permission for the folder...So could you tell me what are the permissions required to be set for this job to be done on server.
while 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 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?
Alright, so i have a silverlight application,
it opens a filedialog, gets the selected file, transfers it to asp.net which saves it to the server, but i want to know how to implement a progress bar for it. for big files, and multiple file uploads, i will need to know the progress of the file upload to the server, is this possible?

View 6 Repliesi have an application with an upload page and require it to be able to upload large files. Everything works well with small files but when it comes time to uploading bigger files i am having troubles... I added <httpRuntime maxRequestLength="2048576" /> in web config but still when i tried uploading a 500MB file it crashes after a few minutes with an error application offline or unavailable after some searching i went to my application in IIS 7.0 went in "Request Filtering" > "Edit Feature Settings" and changed the default value "Maximum allowed content length (Bytes)" to 1500000000 and restarted my app now i do not get the application offline error after i start my upload but instead in seems to go in a never ending loop.. I tried with Google chrome and it displays the percentage of the upload but every time it reaches 100% it restarts back to 0%.
EDIT: It is not a never ending loop after like 40 minutes i get "The webpage is not availale" same message i used to get before i made the changes
I'm developing a httpHandler, in my source code if some conditions aren't met i would like to stop uploading file to the server ( for example file extension is not allowed)
When I try to quit ProcessRequest function with return null;, asp.net tries and uploads the file automatically before I quit the httpHandler...
How can I stop asp.net to automatically upload posted files?
Here is the list of thing I've tested so far and no luck:
public void ProcessRequest(HttpContext context) {
var worker = (HttpWorkerRequest)provider.GetService(typeof(HttpWorkerRequest));
..........
worker.CloseConnection();
context.Response.End();
Environment.Exit(0);
return null;
}
