VS 2008 Upload File With Bytes Uploaded And Multithreading?
May 10, 2011
Dim length As Integer
Dim intOffset As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim clsRequest As System.Net.FtpWebRequest = _
[code]....
What I'm trying to do is get the bytes already uploaded. I cannot seem to do this.Another problem: When uploading, the form will not move or change Label1.text. When pbUpload.value == 100, THEN it changes to a different number than label3.text.

What exactly does this line do?
i = stream.Read(bytes, 0, bytes.Length)
Does it read the entire message string sent by the client? I have a line to write to the stream later in the code and that does not seem to be sending anything back to the client, although the code around is excuting.
i = stream.Read(bytes, 0, bytes.Length)
While (i <> 0)
Try
' Translate data bytes to a ASCII string.

My intention is to open an image file as bytes, Convert the bytes to a string, send bytes to server and server stores bytes in a database. Then I need to reverse the process and be able to convert the bytes to an image.

I have 10 parts of a file. Each part is 10,000 bytes.Now say I receive these parts out of order meaning I cannot simply just write them in order as I receive them, but I am able to detect what part it is.
If I received part 3 how would I write those bytes in the 20,000-30,000 byte section of a file?

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'd like to get both C# and VB.NET sugestion.
I have an ASP.NET FileUpload control, which allows only image type. I used RegularExpressionValidator like below.
<asp:FileUpload ID="fuPhoto" runat="server" TabIndex="40" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator3"
runat="server" ControlToValidate="fuPhoto" Display="Dynamic"
[Code]....
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.
How do I examine the file content being uploaded?

Alright here's my situation: I have a form. This is a very small form that can be moved with the mouse (formborderstyle=none). The transparencyKey is 0,0,1. The form back color is 0,0,1. There is a label on the form. I drag files to this label(its backcolor is black[0,0,0]). What I want is for the filesize to be checked. I already have the uploading to ftpcode, I just want to know if the file is above my limit I set. (250mb per file)

I'm trying to get a specific error message posted when a user tries to upload a file that exceeds the maxrequestlength of 10MB for my asp:fileupload object. However, adding the onError attribute to my fileupload object, the user does not get the error I want displayed; the page just crashes. Setting customerrors mode to on and setting up a redirect page doesn't work either; the page still crashes. How am I supposed to get the page to display a specific error without crashing?

I am developing an application that will do 2 things:
- connect to a webservice
- Upload/download files through WebDAV.
Seems to work fine, but I am having an issue with debugging. Since WebDAV is installed on the server, i have to publish the webservices there aswell, as the webservice is going to access the file locally (serverside) after upload to the server. This makes it impossible for me to debug the webservices. When i switch to the local services for debug, they cannot reach the file that was uploaded to a remote location (the server). Is it possible to install a local WebDAV server, even if i do not have IIS set up? Just for testing purposes?

I am writing a code that downloads alot of information from different servers. Puts the information in an excel spreadsheet, saves the sheet, and uploads it to an FTP page for each server. The code is running into an OutOfMemoryException. Is there a way to clear the memory after each servers file is uploaded to the FTP?Or is there another way to fix the problem with out adding memory to the server the code is running on?

Having no real experience with updater-style applications, basically I want a secondary EXE to be bundled with my application which will update the program file. Its a one file application - so its a simple process. Its just for the PC's inside the business.Currently, I think it will be easiest to get the updater to check a text file uploaded onto our server, and determine whether the running version number is above or below that. The new application will then be downloaded from a simple http link.
-I have an interface designed, so that will be attached to my request.
-Is it possible for the updater to update itself? How could I request that?
-Is there any way I can ask that the link which the updated file will be downloaded from is definitely hidden from the user?
-Will the developer incorporate error handling for if the program is running when the updater runs? How do I ask for that?
Is there a better way for the updating process to run? What other things should I ask the developer to include?

What would be the best way to input the password when uploading a file to FTP? The file gets uploaded behind the scenes without the user inputting any details (the username + password gets used)
So far I've used the network.upload method but the password is in plain text and obviously readable. I need to upload the file without anyone obtaining the password when doing so, would obtaining the password from a mysql database or some sort of encryption be better?

I want to upload a file to a sharepoint document library. This looks extremely easy and trivial but I haven't written any VB in about 10 years, so it's kicking my strASS I have tried looking into using the web services for this, but all of the solutions posted are incomplete, so I've punted and gone after the http put methods. I found this vbscript which works very well, tested on files up to 23MB and it works great.

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.

I want it to do is that you input a string, then you select an algorithm (Theres only going to be one RijnDael) then you input a key, then the Initialization Vector comes from "txtIV.text" then you select the key bytes and the block bytes from the numeric up/down, then you either encrypt or decrypt.
