To upload a file via FTP to an HP3000 server, you would type something like this from an interactive FTP prompt: Put myfile.txt myfile;rec=-32,1,f,ascii;disc=250000 To duplicate this with Chilkat, call PutFile such that the remote filename is “myfile;rec=-32,1,f,ascii;disc=250000”. For example: // This is a C# example, but the same concept applies w/ using Chilkat in any of the supported // […]
This error can happen when trying to transfer a file or list a directory in Active (PORT) mode. The problem is usually solved by switching to Passive mode. Set the Ftp2.Passive property equal to True. Explanation of the problem: In Active mode, the data connection is setup like this: The client sends a PORT command telling the server the port […]
Question (solution is below) Today one of my customer’s got the following connect error when running my application. This same application works just fine on my system as well as almost 100 others. It had run correctly on her computer until she installed an upgrade. The connect error is: Port: 21 Host: www.***.com sockError: 10013 Connect: failed WSAEACCES An attempt […]
Question: We’re rather puzzled by what appears to be capped speeds on uploads, despite no cap being set. Testing uploads, we’re seeing about 350 KB/s via the Ck library to our (local network) FTP server. A FileZilla transfer of the same file to the same server can happily hit up to 7MB/s. I realize Ck supports bandwidth throttling, but those […]
Question: We are trying out the FTP2 ActiveX component for ASP. What we need to do is have people be able to upload files to the web server over the Internet. Is this component able to do this – or can it only FTP files that are already on the web server? Answer: This is a common question. The need […]
Question: There is a possibility that the file to be deleted does not actually exist, so can I do a test first so that i only delete if it is present and thus avoid any nasty warning about missing files? Answer: The Chilkat components/libraries never pop up warnings or display error messages — they simply return success/failure status and provide […]
Explicitly setting the date/time for a file on the FTP server is not a well defined task w/ the FTP protocol. Some servers support the MDTM command. However, MDTM is officially for getting a remote file’s date/time. Some FTP servers allow for using MDTM to set a remote file’s date/time (even though this is not a standard). Some FTP servers […]
One of the most common problems with FTP data transfers (including downloading directory listings) has to do with Passive vs. Active mode. Depending on your client/server/firewall situation, it’s probable that only one of the two modes will work (Active or Passive). Normally, if you choose the mode that doesn’t work, the data connection is blocked and you get a “WSAEWOULDBLOCK” […]
This post describes a strange error on one type of FTP/web server if FrontPage extensions are installed. The error message provided by the FTP server is very misleading. Here is an explanation: When FrontPage Extensions are installed on a domain, FTP access to the htdocs folder, and all of its child folders, is limited to read and list only. There […]
