FtpWebRequest And Large Files?
Jul 24, 2010The underlying connection was closed: An unexpected error occurred on a receive.If I look on te FTP server I can see that the file has been uploaded entirely which led me to believe that the control channel was timing out. I have tried modifying the timeout on the FTP server as well as the ReadWriteTimeout in my code to no avail.Here is my code...
Dim ftprequest As System.Net.FtpWebRequest = DirectCast(System.Net.WebRequest.Create(destination), System.Net.FtpWebRequest)
ftprequest.Credentials = New System.Net.NetworkCredential(username, password)

File I/O And Registry :: AVI Header - Program To Download And Play AVI Files The Files Are Large In Size And Long Time Wise
Dec 11, 2011I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
View 4 RepliesAsp.net - Zero Size Files Uploaded With FTP FileUpload?
Oct 12, 2011I've been reading gobs of articles on FTP upload in ASP.NET recently and they all seem to make sense, but every time I've tried implementing them I either get an empty file uploaded, or no file at all. Here are some of the articles I've been reading:Managing FTP Transfers from an ASP.NET Web Page By John Peterson FileUpload Control Doesn't Give Full Path...How to: Upload Files with the FileUpload Web Server Control I know exactly what the problem is but I don't know how to fix it. I can pass the file name from the FileUpload control, but the path does not exist for security concerns. However, the StreamReader object requires the fully qualified path of the file to be uploaded, so how the heck do I get that? I'm at my wits end!Let's use the example by John Peterson that I linked above. Here's the code:

VS 2005 Required On Getting Multiple Files Size
Jun 5, 2010I need to get file size of some files, which i can get very easily by using FileInfo class.. As of now, I'm looping through all files in My Directory and then taking their file sized into a notepad.But the real problem for me is,Like this, I'm having around 100 Root directories, each contains ~ 1000 subdirectories and each sub directory contains ~ 80 files..Yes, I know, that, I can use a recursive function and loop through all dirs and sub dirs and thus the files.. which was taking huge efforts in terms of time.I want to know, If there was any other alternative, which will make my task more easier and efficient.

My problem comes from when i try to save them to the ftp. Yes my user name and password are correct,otherwise i wouldn't be creating the directory.

Use A Wildcard In The Uri Of An FtpWebRequest To Get File Date?
Oct 14, 2009I am working on an application in vb.net to move files back and forth between a client and a ftp server. We will be creating, deleting, and renaming temporary files during our update process.I want to check for the existence of a temp file before I begin an upload process to keep different users from trying to update the same file at the same time. I have a method (below) to check if the FTP file exists (using ContentLength), but I want to be able to pass in a string with a wildcard such as:
FileServer.FtpFileExists("MyTestFile.*.txt") Can I use a wild card with a FtpWebRequest object? What about a regular expression?

View 2 RepliesBuffering Using Ftpwebrequest - Allows Users To Login To The System
Mar 15, 2011This will be my first post on this site, so I thought I would make it a doozy. I have an web application on our site at work that allows users to login to the system, and submit filings for dockets that our state agency governs. Without getting to involve with what that means, they basically upload mostly .pdf files, but there are others that are acceptable to upload as well. The current system that is being used, uses a simple FileUpload and saving it to a folder on the d: drive of the webserver. I ran into a problem that with anyone outside the building/network, the upload is extremely slow and seems to be limited files no larger than about 1.4MB. There have been a few cases where larger file have made it through, but those ar few and far between. I've tried a couple different 3rd party components, but seem to run into the same limits. So, I install the FTP server on the box with the IIS and am trying to go the FTP route using ftpwebrequest.
Below is what I have put together so far:
Imports System.Net
Imports System.IO
Partial Class _Default
[CODE]...
This seems to work as it is at the moment, but I know it has a long way to go for catch exeptions, speeding it up...
1.) The first problem I have run into is if you try to upload to large a file, you get Out of memory error. I'm needing to change the buffer so that it is buffering chunks instead of the entire file. I've googled over and over again and seem to find several good options in C#, but can't seem to convert them to VB. So, could some one give me some idea how to take what I have and change the buffering to use smaller chunks.
2.) I need to catch an empty UploadFile field.
3.) I will eventually be changing this so that it handle multiple file uploads like my current system uses. (Did I mention that I'm new to the ASP.NET and have been programming in .ASP)
4.) As you will notice from my list of acceptable file types, I might have a problem with some needing to be upload as Binary and some not. So I'm going to have to come up with a way to test and change the Requested.UseBinary = False as needed.
I'm sure that I'll find other items as I progress or the big bosses will find other things that they want to add, but for now.... I know that given enough time, I will get all of these items worked out.
By the way, we have a network adminstrator that leave a lot to be desired and most IIS and now FTP I'm having to learn, implement and configure. I'm wondering if there is anything else that could be causing these limits in file size. Since I've tried 4 completely different forms of uploads and they all seem to run into the same limits, I thought there might be something in a router, firewall, server configuration.... that I might need to look into as well.

I want to create new directories and then upload files into them but thought it best to check if the directory already exists. Although attmepting to create a directory that already exists does not seem to cause any errors, it does waste a bit of time.
This code reliably checks if a FILE exists:

I have attempted to modify this with ListDirectory in place of GetDateTimestamp (to check if a directory exists) but it seems no exception is thrown whether the directory exists or not. I've done lots of Googling but haven't found a satisfactory answer.
