i am developing file upload application,i have .ashx file where i have a value in a string variable mydata.
in my .aspx page when i click on any button then data which is store in mydata variable in ashx file it show in text box.
I'm currently developing a web application whose primary user function is uploading and downloading of files. The files will be stored on the hard disk (no cloud storage yet).
Taking into consideration the possibilities of gigabytes of data and a large number of files, do I need to organize files into sub folders to account for the fetching of a file or is the file system's indexing already very efficient and I can ignore this potential bottle neck?
Update:
On a side note, I plan to store file names and any additional information in a SQL database and only query the disk when a user actually wants to download the file. This is how I plan on retrieving files:
FileStream stream = File.Open("C:file.txt");
byte[] fileContent = new byte[stream.Length];
stream.Read(fileContent, 0, fileContent.Length;
Any file information will be retrieved from the database. The hard disk will only be used for saving and fetching files.
Update 2:
Files will be saved as GUID + EXTENSION on the hard disk while the actual file name is stored in the database.

The usee then fills out the rest of the form and then saves the document.With the image extraction, I was owndering if it was possible to do that as an ajax post. The other submit button can work as a normal http post

View 1 Repliesi m using asp.net fileUploader controle to upload file in mobile application but file is not uploading.
View 1 RepliesMy application allows a user to upload a file using the FileUpload control. The data contained in the uploaded file is then displayed to the user in a Grid for review if certain field validation criteria is met otherwise, a message is displayed stating that invalid data was encountered. If the data displayed is satisfactory, they have a 'Process Data' button to add the data to the system.
Initially, I used a simple If/Else block to determine if there was a file selected or not and if not, display a message to the user. As the coding got more complicated, this stopped working and I was told to use the RequiredFieldValidator control instead to get around the issues that arose.Now, I have a new issue: after the uploaded file data passes field criteria validation, the FileUpload box is cleared automatically and so when the user clicks the 'Process Data' button, the VC throws a message stating that the file name is missing from the FileUpload box.

View 2 RepliesI've read several questions explaining how to handle file uploads in asp.net mvc. I am trying to submit both the file as well as form fields describing it. That might be the issue. I'll go write to the code:
View code:
<% using (Html.BeginForm("CreateFile", "Video", FormMethod.Post, new { enctype = "multipart/form-data" }))
{%>
<fieldset>
<legend>Fields</legend>
<p>
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
</p>
<p>
<label for="Password">Password:</label>
<%= Html.TextBox("Password")%>
<%= Html.ValidationMessage("Password", "*")%>
</p>
<p>
<label for="Description">Description:</label>
<%= Html.TextBox("Description")%>
<%= Html.ValidationMessage("Description", "*")%>
</p>
<p>
<label for="DateUploaded">DateUploaded:</label>
<%= Html.TextBox("DateUploaded")%>
<%= Html.ValidationMessage("DateUploaded", "*")%>
</p>
<p>
<label for="DateRecorded">DateRecorded:</label>
<%= Html.TextBox("DateRecorded")%>
<%= Html.ValidationMessage("DateRecorded", "*")%>
</p>
<p>
<input type="submit" value="Submit" />
</p>
</fieldset>
<% } %>
Controller code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult CreateFile(VideoDTO video, HttpPostedFileBase f) //[Bind(Exclude="VideoId")]
{
foreach (string file in Request.Files)
{
HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
if (hpf.ContentLength == 0)
continue;
string savedFileName = Server.MapPath("Videos") + Path.GetFileName(hpf.FileName);
hpf.SaveAs(savedFileName);
video.FileName = hpf.FileName;
}
repository.CreateVideo(video);
return RedirectToAction("Index");
}
I've seen several examples, but haven't come across one that is trying to submit both a file and other form data. Some other things of note is other examples seem to not put a HttpVerb attribute on the action method at all and have an empty parameter string. The files I'm looking to accept will be video files of various types but they can be anywhere from 100-300 mb. The files I've attempted to use (locally) have been rather small comparatively (50 or so mb).I know it's been asked but I feel like my issue here is different somehow. When I submit the page I see:
The connection was reset
The connection to the server was reset while the page was loading.
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.
