I'm studying how to use Visual basics 2010, and I have been asked to create a program that transfers a audio file to one machine, then plays that file when it receives it on the other machine. I have made a basic file transfer, but when I install it onto a computer, the server crashes for some reason. But it will work on some computers. Here is my code for the server:
I also have to make the program so that the client can click a button and then it will play a preset audio file. (example: User clicks button to play a fire drill)So to sum it all up, The server app goes onto the computer that will be playing the audio and the client app allows you to send audio files to it and play
I will use the Background Intelligent Transfer Service (BITS) to transfer files from a client (laptop) to a shared folder on a server within our local network.The problem is a very slow network bandwith, if we transfer a file, the other clients canīt work, all requests to other clients (application) or viewing internet pages needs a long time.My idea is to use BITS in my tool to copy/transfer a file from client to server, also I hope to get more performance for the internet requests.
i would like my application to transfer over two peices of string two a second form, it will be the forename and the surname and i would like them to keep the information entered
Form 1 Public Class Form1 Private Sub Your_DetailsBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
am writing the pgm using vb.net to get the file from reomte machine & store it on local machine using FTP . but am always getting an error like "remote machine returned an error :(550) file un avaliable (e.g , file not found, no access)
Dim reqFTP As FtpWebRequest Dim filepath As String Dim filename As String Dim filename1 As String
I'm creating a database management program and I just got started. I will be using a login form and a form that is the management part. The MySQL connection will be created on the login form and I was wondering how to get it to the other form. What I thought I should do is create a public mysqlconnection property on the login form and just use it from there. I don't think I have ever known the correct way of transferring a mysqlconnection over 2 forms.
I'm trying to make a program that takes my old records from Access and moves them to MySQL. Its supposed to take records from 3 different tables in Access to 3 different tables in MySQL. The first table is "Orders" and it sorts the ones to pull to the dataset, taxDS, by "Where Status = 'Waiting Payment' OR 'Cancelled'". Then the second table pulls its info(this is where i'm having trouble) by the "Control_Number" in the "Orders" table, so basically if the control number isnt already in the dataset its not going to pull the data into the new table "FNF Taxes".

I wrote some code to share files throughout my network. The thing is that i don't understand how to determine how much the client has sent already and how much is left. I have posted my code below so you guys can see what I'm talking about.[code]...
I need to transfer files from one server to multiple cients (using the internet) in the fastest possible way in .NET . What are the different types of transfer protocols which can be used in .NET or VB.NET so that the files are sent in a very short time ? I have tried using FTP, but that is slow because it requires authentication, handshaking etc. What i want to know is the options which we have in .NET for sending files in the fastest possible way between a server and multiple clients.
I am writing a program in vb.net 2008 and need to be able to send and receive files using Zmodem through the a comport. I have search the net and have not found much to do with Zmodem in VB.net. I am already using the System.IO.Ports.SerialPort to send and receive commands through the comport but how to send or receive a file using the Zmodem protocol.
I want to transfer a file from one computer to another computer by giving the port number and IP address. There will be an other software waiting for the file to be received.
Basically I want to take My Client.Then for example Lets say in my client I have "A = 1" Then my 2nd file which has random data in it.So Client= My Client File = The File which I want in the end result
How could I Inject "A = TextBox1.Text" from Client to File.I heard it's called "End Of File" or something like that.
I need to transfer a block of pixel values as quickly as possible to a picturebox control. The data will be in a byte array representing 512 pixels by 4 lines. The data is greyscale values from 0 to 255 but I could easily store each value three times to represent R, G and B if that made it easier/quicker to write the values to the picturebox.I've used fastpix (by Vic Joseph "Boops Boops") in the past but this seems more geared towards fast plotting of individual pixels and as I have a pre-formatted block of pixel data I was wondering about alternatives. I've done a bit of research and BitBlt seems interesting, but can this be used with a byte array as the "source"? All the examples I've seen are for transferring/merging between bitmaps/pictureboxes. How about Direct Memory Access? I just need a simple "brute force" method of getting my pre-formatted data into the picturebox. Oh, when I say "fast" I mean I'd like to plot my 512 x 4 pixels in less than 10mS.
How will I transfer deleted record into another table instead of deleting it permanently? I think it is what we call "history"..somehow..For example I have 2 tables. 1 is Original_Record the other is Deleted_Record. If I deleted one record in Original_Record, the deleted record will be transfered into Deleted_Record table.
I am writing a chat program and im adding a transfer file function but Ive hit i bit of a snag..The way my program knows its a file coming and not a regular text message is i added a 3-6 bytes prefix depending on what is being sent.
[Code]...
Ive tried the copyto method but since my file byte array is empty it throws an exception. If i wasn't clear with something let me know and i will try to explain better.
I'm encountering problems when i want to download files from my server to my clients. My client is able to connect to my server but it will never transfer the file over to my client and i am unable to solve it.
Is the FTM available for .net users to use on our web solutions or sites?I have some large install files on my site that the regular download will quit in the middle.the ftm at least allows for interruptions.I tried the FTP route, but turns out most users out there have no idea what ftp is. I saw a library that eluded to IDownloadManager, but I wasn't sure if this was the same thing as the ftm.
I'm transferring from one FTP (a Dev site) to another FTP (a Test site). Spare me the thoughts of changing this process. In any case, here's my method:
Public Function TransferFile(originalFile As String, destinationFile As String) As String Try 'FileStream for holding the file Dim uploadRequest As FtpWebRequest = WebRequest.Create(destinationFile) uploadRequest.Method = WebRequestMethods.Ftp.UploadFile [Code] .....
This works perfectly for ASPX files and their .vb code behinds. When we try to transfer .DLL files, they show up on the server as 0 bytes, and sometimes actually transfer. The problem is that, despite being the same size as the original, they act as if they are corrupt.
1. How much load or data size our custom encryption/decryption algorithm can handle? E.g. what's the limit of file size that normal encryption/decryption algorithm supports.
2. What's the best way to use encryption while file transfer via internet?
3. Where and when encryption and decryption has to apply while uploading and downloading content from internet(Hosting on client or server machines)?
4. What type of algorithms suites for above approaches?
5. How much time it takes to encrypt / decrypt data for 10 MB, 100 MB, 1 GB etc
