Asp.net - Make The ASP File Upload Control Accept Large Files?
May 9, 2011
I would like to upload files using the ASP FileUpload control. However, if I try and increase the limit to about 10000 kB, it doesn't work and accepts files only upto 4 MB in size and I get an error saying that the connection to the server was reset. I referred: [URL]..but when I modified the web.config.comments file, nothing happened. Where am I going wrong?
Also, I wanted to know how this would work when I deploy it on the web server. I'm asking because in the code behind, I'm still giving a hard coded value for the path where the file is to be uploaded. How does this work?

I am trying to upload 2 large files to a ftp server by uploading as one file to a location. I have it working if the files are small but it crashes with large files.
For i As Integer = 0 To filelist.Count() - 1
Dim fRequest As FtpWebRequest = WebRequest.Create(ftpPath & "/Reports/" & filelist.Item(i))
fRequest.Credentials = New NetworkCredential(username, psswd)

I'm trying to upload a large file (over 50Mb) to my webserver but my app hangs when trying to close the stream. If the file uploaded is larger than 50Mb then the .Close() causes it to hang - no error message at all - however a file less than 50Mb succeeds.
What do you suggest to get around the fstream.Close() hanging my app?
Dim target As New Uri(uploadedFilePath)
Dim fRequest As System.Net.FtpWebRequest = System.Net.WebRequest.Create(target)

I want to upload a large file of tracking numbers and process them into our ordering system.
I used to use Server.ScriptTimeout = 3000
It worked until we upgraded our servers and now it crashes.
I'm Getting This webpage is not available The connection to www.YourSite.com was interrupted.
I could see the .csv file has been uploaded, but many tracking numbers do not get processed.
I'm thinking of maybe switching to a asynchronous update. But I cannot find any good source for it.
If you have any good ideas, please let me know.

How do I make a textbox control to accept dates only and convert to a valid date format? I don't want to use the calander control. e.g. if I enter 2/17 or 2-17 or 02/17 or 2/17/2012; it will convert to 2/17/2012

I 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.

I'm wanting to create a control that allows users to upload PDF files and PDF files only. I know that there are object properties for windows forms that allow certain file types, is there anything for win apps? Or do you just have to check the end file extension after they tried to upload it and display an error? I've never done anything with web app uploading before.

I need to find a good control for VB.Net to upload big files to an FTP server:
Can upload files up to 10GB
Uses passive mode
Provides feedback during upload, to make sure it's going OK
Can cancel and resume
Up to two concurrent connections
I read about WebClient + NetworkCredential, but it doesn't seem to provide progress infos. There are also the FTPWebRequest/FTPWebResponse classes from WebRequest/WebResponse, as well as WebClient.UploadFileAsync.

[Code] each file is about 30 kilobytes in size, and they contain raw hardware statistical information in a comma-deliminted format. I want to do the following with these files as my end-result.
NEWFILE.CVS contains the contents in this format:
metric_group_001 metric_group_002 metric_group_003 metric_group_004 etc.
I don't want APPEND, I want to concatenate the contents of these files into one large master file. I am able to do this MANUALLY, but I need to have a DYNAMIC method of doing this because of the number of files will change depending on the test we are doing with the hardware. This is the code I am using to do this process manually and it does work, but I need a DYNAMIC method in place. [Code]

I am using zipforge.net to archive files in a small backup program I am creating. Everything works fine however if I try to archive a large number of files the process of zipping them gets slower the further along in the job it gets.
Example: I have a directory that contains a little over 100,000 files in it. Each file is only about 200k of text. When I use the zipforge zip class it starts zip'ing very quickly but as it gets about 40% of the way through the directory it starts to slow down... at about 60% its working at a snails pace.
Memory usage for my solution also goes up proportionate to the archive file size as it grows. Currently it takes around 26hours to backup this directory which only contains 4 gigs worth of information.
If I use a program like winzip I can zip the folder in less than an hour. I am thinking there has to be a way to write to the end of the zip file without having to open it every time or without keeping it open. My backup software scans the specified folder and writes each file path and name into a text file. Then it reads the text file line by line and passes the path + file info to the zipforge addfile().

I wrote a cleanup program to go through some directories and delete files based on if the creation date is older than say 6 months. It works fine with some of the directories I have that contain around a few thousand small files. However, there is one directory (that contains small backup files from another program) that is loaded with over 300,000 files and it locks up on me as soon as I read in the first file in that directory.I am convinced it is the directory has too many files in it to open it. The server that the directory is on is slow. It takes a half hour to open the directory while on the server itself. I know it will take forever to delete the amount of files I want to delete, but I don't understand why it gets stuck and hangs there with no error message.Here is where I get stuck. Listbox1 is the directory I'm attempting to access

I'm using "My.Computer.FileSystem.CopyDirectory(...)" to copy large directories (30-50gb) from one mapped share folder to another. Using "FileInfo.length" to add up all file and subfolder sizes, determines the 'origin directory' size just fine. However, if I use the same method for determining the size of the 'destination directory', mid copy, it returns the full file size, despite the copy not yet being complete.I'm at a loss as to why, as this method works fine in testing, going from a local PC t

I am trying to develop an app that will export a large amount of zip files all of which have the same single file in them - simply named 'dw' (with no extension). They will all be in the same directory. I want the file 'dw' to be renamed to the zip file name + .tif. (I will actually eventually need for this to use the magic number to determine if the file is a .tif or a .rtf.) I have been able to get it to cycle through, if the file is NOT renamed. I seem to run into issues when I want the file renamed. It just creates the first .tif file and thats it. I think its actually just cycling through but everything is getting that same name. For the record i am not a programmer by trade, just trying to help with something at work - thus I know the code I have peiced together probably isn't 'by the book'

I am pretty new at VB but am trying to design an application that will allow a user to select from files on his or her PC, hit a '>>' button, and those files will appear in a list on the right side of the button (so I can then have the application upload those files via ftp). I am planning to use a TreeView control to act as a file explorer in the application. I have been unable to find any resources on the internet to populate the tree view with the user's local file structure, and was wondering if anyone could point me in the right direction.
