View 4 RepliesI 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?

View 1 RepliesI need large file upload support in my hosted (godaddy) medium trust asp.net app.It obviously needs to be responsive with indication of progress, so handling the stream myself is important.This all seems pretty simple and works well when in full trust:
1.Write an HttpModule that listens for file uploads.
2.Get the HttpWorkerRequest object from the Context using reflection.
3.Write out stream to a FileStream
All very well and good except that I keep getting permission exceptions when trying to get the HttpWorkerRequest object from the context in medium trust. Whether I use reflection or I use System.IServiceProvider.GetService() to get the object (which is clearly using reflection), I get the same error.
I have also tried using System.Web.HttpPostedFile. It has a property InputStream. But it seems this object is uploading the entire file on initialization, so no good.I have googled myself tired, and can't find another alternative.
Even if it is a security risk to let users have the HttpWorkerRequest object, surely the framework provides another way to handle the stream of files when Method="POST" and enctype="multipart/form-data"

View 3 RepliesThis works in other browsers but not in chrome. I am trying to allow users to upload large files and have an ajax call to update them on the progress of the file upload.
So a unique ID is generated on the client side and added to the action of the form before sending. Then the form is submitted (form only contains a file upload input) and an ajax call is made to get the progress of the upload. The ajax call goes to another page and uses the ID to lookup the upload.
I am using JQuery 1.5.1. Debugging this and putting something on the error function give me nothing other than "error". Not very helpful. I used Chrome's debugger and it just says failed to load resource xxxx.aspx. xxx.aspx is the URL i needed. Turns out that there seems to be some sort of conflict between the form and the ajax call.
There is a requirement like in a web page having FileUpload control and button. I need to upload excel records to sql database. If the excel file having less than 1000 records then it is executing fine and if the excel file having more than 1000 records then it's giving me the error message like bad request (error code: 400). As per my requirement need to upload minimum 4000 to 5000 records on button click. Some times it is working fine in IE browser but not all the times. In mozilla not at all working if records having more than 1000. How can i over come this issue.
View 1 Replies after i can copy my file to another folder i realised that if this webapplication is used by multiple users at once, then some users are going to get locked out because each one is trying to copy those files.
so how do i tell the user thats trying to use a file to wait untill the file is available.
StreamWriter WriterTotxt = new StreamWriter("date.txt", false);
DateTime LastAccess = File.GetLastWriteTime("path.dbf");
WriterTotxt.Write(LastAccess);
WriterTotxt.Flush();
WriterTotxt.Close();
string ReadTextFile = File.ReadAllText(txtFile);
DateTime test = Convert.ToDateTime(ReadTextFile);
if (File.GetLastWriteTime(LatestUpdatedTime).CompareTo(test) > 0)
{
File.Copy(Path.Combine(sourcefile, fName), Path.Combine(destinationfile, fName), true);
}
I have a async file upload control.What I want is when the file is loading on the server I want show a progress message "Loading...." not the default image in async file upload and disable the upload button during this period. Sometimes when the file size is large it takes time to load the file on the server and in between user may click the upload button where the file is not loaded on the server yet.
