implicit ftp - SSL problem

hi,

i've found out here:
http://forums.microsoft.com/MSDN/Sho...31195&SiteID=1
that FtpWebRequest does not support implicit connections. I have a
serious problem with that, because i need to talk to an Ftp server that
supports only the explicit connections. changing the server is out of
question. and i need ssl to keep login and password secure. to make
things worse i can only log in using ssl. then i need to use Clear Data
channel.

does anyone have any ideas what to do? i didn't dig too deep into this
but is it possible to implement the explicit ssl without rewriting the
whole FtpWebRequest class?

sorry guys, of course i meant *implicit* here :)

to make things clear: i need implicit ssl implementation.

If you really want to do this, your best bet is to write it as an FTP
proxy - but then, why not just buy an implicit SSL FTP proxy, which is far
cheaper than writing it, and use that?

While I'm here, I might as well note that implicit SSL FTP has been
deprecated for well over a year, and was deprecated well before the FTP over
SSL / TLS specification became an official RFC document. Supporting
implicit SSL FTP is a bad idea. It was a dead end before it got started.

use it instead of FtpWebRequest introduced in 2.0 framework.

Hi all, I'm working on migrating my code from KCC to gcc, and I'm having some issues with "implicit typename" warnings from gcc. Essentially, what happens is described by this example: template <typename cell_data_type> class cell {}; template <typename a> class c1 { public: typedef cell<a> T_cell;

Hi, I've a problem: I compile modules of embedded SQL (for a dynamic lib) on multiple platforms (AIX,Linux,Windows). They are compiled from the same source code. To be able to provide all platforms at the same time on ONE database (server), I want different package names - e.g. module1.sqc should produce packages AMOD1, LMOD1, and WMOD1. So I tried the following db2 call for preparing:

Could anyone please help me to understand what is happening here? The commented line produces an error, which is what I expected given that there is no conversion defined from type double to type Test. I expected the same error from the following line, but it compiles fine. The double is silently truncated to an int and then fed in to the implicit conversion operator. Why does this happen? Is there any way that I can keep the implicit...

Im trying to understand implicit type conversions from object -> string and vice versa. I have two classes, one Driver and one called StringWrapper. These are just test classes that try and emulate the pattern im trying to follow in an existing project. These are my steps: 1) I have a method "printMe" existing in the application which originally used to take in a string. This method is static and sits in the Driver

Hi All, Please excuse me, but the bulk of my post will be a code post. It describes some weirdness with regards to the implicit casting operator. The crux of the problem is this: I want to set a property on a class that takes an interface instance. I have a class that can cast implicit to a class that impliments said interface, but the compiler moans and says it cannot cast implicitly like that.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
