Asp.net - Zero Size Files Uploaded With FTP FileUpload?
Oct 12, 2011
I'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:
Protected Sub btnUploadFile_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myFtpWebRequest As FtpWebRequest
Dim myFtpWebResponse As FtpWebResponse
Normally when user upload a picture, how do u control the size of the picture uploaded by the user?
is there a way to change the size picture (scale the image according my size 300 x 150). Let say an user upload an image with (500 x 300), using picturebox, can i scale the image (500 x 300) to my picturebox size so that it can looks perfectly nice?
I have deployed my Website on Windows Server 2007. in IIS..I have added asp:FileUpload control..i have set <httpRuntime maxRequestLength="60000"/> under the <system.web> in my Web.Config file but website doesn't allowed to Save the the file of maxlength as specified in web.config file.
I'm working on a form where a user can submit a file through asp:fileupload, but want to display a specific error message if the user uploads a file exceeding 10MB. However, when I put a try catch statement, my error message does not get displayed, only the default one.How do I make sure it gets displayed?
Try If fuAttach.HasFile Then Dim filename As String = fuAttach.FileName
If you were to upload a project to any site but are concerned about the large file size, what are the only files you need to zip up for your project to work for either VB 2008 or VB 2010? So far I know you don't need the exe's, the pdbs, and xml files.
So, in this program I added 2 necessary login codes let's say, first a code that I will provide and then the username and password from my website. I implemented both ways, the first one worked perfectly, however, the second one is giving me some problems, my idea for that control was not using a database of users, that was going to be too complicated for a 14 year old guy, so I decided to take the source code for my website and I took a fragment, the boxes for the login, username, password, forgot your password, remember me and some other boxes, great, that worked perfectly, I uploaded the HTML modified document to my website's files and linked it to the URL of the webbrowser control in one new form, good, it's working, but I wanted a simple condition that works for this function "When the webbrowser loads the success website, hide me and show the past login form, when this one shows the failed login, popup a messagebox that says the error.". I have been looking for that simple condition for a long time. I am using Visual Basic 2010 Express Edition.
I want to be able to select multiple files when I click browse on the FileUpload browse button. I have it now to where I can choose one file and add it as a list using a jquery but would I would like is to select multiple files to be added when I click open. Is there a simple way of doing this and is there maybe some kind of javascript that might be able to handle this event?
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 have created an vb.net windows application. In the application i have 2 xml files (e.g., Pre.xml & Post.xml) & the 2 files are same structure.
My requirement is compare the pre & post xml files and get the differences between xml files. Like what are all the newly added nodes, removed nodes and modified nodes as well.
I tried with XmlDiffPatch.Dll, it is working for small size xml files, but in my case xml file size should be upto 100+ mb.
I 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.
Is there an easy way to edit the code below so that it copes (works the same) if the embedded resource is not a plain text file, but a compressed text file?
Dim tempList() As String tempList = My.Resources.ENABLE.Split({Environment.NewLine}, StringSplitOptions.None) For Each strWord In tempList enableFullList.Add(New Words(strWord)) Next
I have seen System.IO.Compression but can't work out what to do, DeflateStream, GZipStream etc.
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
Private Function FolderSize(ByVal dir As String) As Long Dim Size As Long = 0 Dim d As New DirectoryInfo(dir)
I made a form in ASP.NET with VB background code.my problem is I want to make that the file which is been uploaded to by the form to change to "Resemey.doc" instead for example "012 MaraCSD.doc"did a bit of research and found out I need to add some code to my vb code.but couldn't find what, and where to put it.
this is my code:
'Add the namespace for the email-related classes Imports System.Net.Mail Partial Class SendAttachment
I need a snippet to check file for validity (I'm allowing users to upload xml files). So I need to check whether uploaded file is XML. The best I can think of is just check if extension is ".xml". What if its replaced?
I put in the iframe tag as follows in my .aspx page - Now what code do I put in javascript or vb.net to make this auto resizable depending on the size of the page that comes in?
This method will only verify the file's extension, not its actual type. Once I receive the file, I want to examine its contents to determine what it really is, in this case image only.
i would like to create a fixed size frame for user photos uploaded. I've tought: i, can create a fixed sized image (200 width x 600 height for example), with my personal frame (top, left, bottom, right element graphics) , and in the center a transparency.
Ok, but i don't know how to merge the photo into the frame and save the new photo format.
I'm using the code below to send large strings (500kB) to a server. I'd like to show the upload speed and in order to do that, I need to calculate the amount uploaded every second.
In a Timer that fires every second I get the BytesUploaded, divide it by 1024 in order to get KiloBytes (kB/s) and show it to the user. Then I set BytesUploaded to 0 and one second later do the same process.
The uploading is done asynchronously and the size of the data is added to BytesUploaded at once. This means that BytesUploaded is not being updated in a constant flow and has a totally different value almost every second.
