Question: A quickie question about the FTP2 control. I have some clients with strange FTP servers that return the directory listings in formats that no control seems to be able to handle (although I have not tried yours!). However, it is next to impossible to test, since I do not have access to their server. For them, we use the […]
The Chilkat VC++ static libraries are for unmanaged C++ applications. A Managed C++ application (using Microsoft’s Managed Extensions for C++) runs within the .NET Framework and therefore must use the Chilkat .NET assembly. The Chilkat C++ online reference documentation and online examples are for unmanaged C++ applications. For Managed C++, the best choice is to read the C# online documentation […]
I get the following support problem about once per week from ASP developers: The ASP developer wants to upload a file from the client computer where the browser is running, to an FTP server. He writes ASP code to do the FTP upload, but cannot understand why the file is not found. The thing the ASP developer doesn’t realize is […]
There are many FTP2 component properties that affect how data connections are established between the FTP client (Chilkat FTP2) and the FTP server. Finding a workable combination of property settings for a given client/server situation can be difficult. This blog post can hopefully provide some guidance.

Question: I’ve downloaded the trial version of your FTP2 ActiveX control. I’m using it in Visual FoxPro 9, but need to have a progress bar to track an upload.

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 […]
