Sending files over Winsock
I know how to send small amounts of text, but what about sending larger files in excess of 10kb? Please provide some source code as I have tried to do it, but utterly failed...I would be wanting to DUPLICATE EXACTLY a file from one PC to another PC. (They are already connected with winsock etc etc)
Would you go with ftp (small) and its source code?
Use filecopy (API) then if u are not developing a web application.
Private Const ftpDIR As Integer = 0

FILE: VBFTP.EXE: Implementing FTP Using WinInet API from VB
Last reviewed: October 24, 1997
Article ID: Q175179 The information in this article applies to:
Microsoft Visual Basic Professional and Enterprise Editions for Windows, versions 4.0, 5.0
SUMMARY
VBFTP.EXE is a sample that implements FTP connection, download, and upload using the WinInet FTP API from Visual Basic. It demonstrates the APIs and techniques to set FTP connection attributes and transfer mode that are not exposed inthe MS Internet Transfer Control.
The sample requires Visual Basic SP2 or Visual Studio SP2 installed to run because it uses the updated comctl32.ocx from those Service Packs.
When adding FTP functionality to your application, it is important to understand the capability and limitation of each of the different Internet technologies. At the lowest level, you could use the Microsoft Winsock Control to send commands directly to FTP server port 21. The sequence and syntax of the commands you send to the server would have to follow the specification of the FTP protocol. The WinInet FTP API wraps the socket code and most low-level FTP commands and provides a set of much simpler task-oriented APIs that do not require detailed knowledge of FTP protocol. However, there is a chance that some FTP servers use FTP commands not implemented by WinInet. If this happens, you have to use the Microsoft Winsock Control to communicate with the server directly at the protocol level. Test your FTP server with the VBFTPJR sample before you decide whether to choose WinInet API or the Winsock Control. The Microsoft Internet Transfer Control, on the other hand, offers a more simplified interface than WinInet but offers less flexibility and cannot be used if you want to customize the connection and transfer mode.
If you are using a proxy to access an FTP server, the proxy has to be capable of handling FTP commands and cannot be a CERN proxy. Please see the following article in the Microsoft Knowledge Base for more information:

Lots of ideas! Hmmm....most of them seem to use the INet control, and not winsock...Is there a way to do it with winsock? If not, I'll award the pts to whoever duz it with Inet(which I will be checking after this...)
ASKER
Nah....I can't figure out how to use the damned Inet...maybe just implement the code for simply sending a file...I dont need a fully pledged FTP client

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
P.S. If you wanna see some more cool winsock stuff, go to my web site. http://members.tripod.com/~Kacklehorn. Theres a OOB tester code out there, and a winsock mailer, to send email.
