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.

I really need to know if its possible because I'm making a messaging client since me and my friend find believe MSN is getting buggier. I've looked on how to do it but none of them worked for me, or were server to client. I want to make it client to server to clients but I don't know how! I know I shouldn't tell you to give me code but maybe give me a few tips on this. Me and my friend share files nearly everyday.
View 11 RepliesI have created an FTP client that uses pasv mode to transfer file in VB.NET.while downloading a list of files the often times the application will hang on the socket.recieve command of the data channel and never return.I have tried setting the timeout to forever, and waited hours.We control the ftp server, it is IIS 7.5.I can not duplicate the issue in house.It only seems to be happening in the client enviroment
I examined the ftp logs of our server and there is no difference between a successfull transfer and a failed.I also examinid our firewall and no port blocking has occured
I create an automatic ftp file downloader by using FTPwebrequest. In which, is there any possible to download multiple files simultaneously using Asynchrounous and threading concept?

I am using Peter Huber's POP3 client to connect to gmail and download messages.The inboxes being accessed are transactional inboxes used only for code-access. That is, a message comes in with a order file attached, code will process it and then delete the message. One stipulation of the code though was a DEBUG flag, which if set would prevent the code from deleting the message so that you can run the program again later without the debug flag and reprocess the message. So, in my code I have If Not Arguments.Debug Then pop.DeleteEmail(eid)
This works fine. Problem is, even when not deleting the message, running the program a second time will not re-retrieve the message, even though if I login to gmail and look at the inbox, it is still there. The only way I can get the program to see the message again is to forward the message back to the same inbox. But in Peter's code I do not see anywhere where he is keeping track of seen messages between sessions.
Is this something that is done on gmail's end? Refusing to deliver a message to the same client a second time? If so, is there any way I can change my gmail account so that it will always show all messages in the inbox to a client when retrieving the list of messages, even ones already "seen"? I don't see anything in the gmail settings screen.adding a method to send a RSET command to the server, as per this comment on the codeproject page.
they need to make some compare version between host version and client version.. and each 1 version different will download the file to the client..[URL]..with both example, how can i make a program in VB.NET just like i said just now?
View 15 RepliesI'm converting a bunch of FOXPRO / FOXWEB apps to ASP.NET.
The underlying DB is still foxpro (for the moment).
I am passing a table to some VB.NET code that I want to have converted to a CSV file and sent back to the client for download. And it works! Sort of ... It works sometimes, but at other times, instead of asking me if I want to download the CSV file, it just spews the file to the browser window. [code]...
when i transfer the bytes sent by the client program to a string the string length is affected.when i put the bytes sent by the client program to a message box. it returns the corrrect text. but when i check the length it will return 8192 or higher. but the actual size is just 5.

View 1 RepliesI have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.

I want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds.
Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files?

View 2 RepliesI 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.

We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.
