A standard synchronizing program will not work if NTP (Network Time Protocol) is suppressed by a proxy or a firewall.
This synchronizer uses plain access to WWW pages that show standard GMT time. It will work if you have access to Internet Web pages.
The unique Time Offset feature of the program allows setting up your PC clock to gain or to lose for a specified interval. Many our users value this feature greatly. Clock in your PC needs to be corrected only several times a month. And it is this fact that defines the way the program works: the program runs when Windows starts, checks whether synchronization has been done this day already, and stops immediately if so. Otherwise the program checks for Internet connection, then tries to synchronize your clock and ends its work if succeeded. So as you see mostly the program is idle and is not wasting resources of your PC. Synchronization is done automatically while you are receiving your e-mail or surfing the web and no actions are to be done by you. The program uses three different time sources.

WeOnlyDo! SmtpServer ActiveX control is a component that can be easily integrated into your applications to provide full non-relaying Smtp (Simple Mail Transfer Protocol) server implementation.
All you need to do is to put it on VB form, call it's Start method and it's immediately accepting connections by your clients! It fully supports commands defined in RFC2821.

Use your favorite mail client (such as Outlook Express or Eudora) to send mail to other users on your network . How? That's easy part: just put SmtpServer control on your form, add some code around and it's all setup to be used.
If you dislike adding additional code - it's fine by Smtp. It will still work, and accept all emails but delete them immediately after user disconnects. But, if you define real filename on your disk, all the emails will be stored to that file. Still, if you want to make real Smtp server application, look no more for native support for socket related material - you just found it.
Smtp server will deal with clients and connections - you must deal with messages. Once new user connects to your Smtp server, you need to provide some way of storing message posted by user to some file on disk, or just read it from Body property and store manually to, for example, database. This is really easy task. If you keep all the emails in separate files, that's just great for usage with WeOnlyDo! Smtp server.
If you prefer to keep it in one large file - we will not argue about it. You can specify filename, make Smtp server Append to that file, and everything will still work just great. As a result, you will have one mailbox for each user just like on UNIX computers.
Together with WeOnlyDo! Pop3 server, you can make powerful fully maintained mail service application that will share emails in your company, receive them from internet and anything else you can imagine. You can even create emails for your employees on the fly. You can make Smtp store to same files from where Pop3 reads them.

Client component that provides support for communication with remote console-type services.
Most commonly, it will be used for Telnet based servers (running on UNIX OS), but wodSSH does even more: it allows you to communicate encrypted (and secured, of course) with SSH1 and SSH2 (secure-shell) servers, as well as any other non-encrypted server (such as SMTP or POP3).
For ones that don't know - the SSH transport layer is a secure low level transport protocol. It provides strong encryption, cryptographic host authentication, and integrity protection.

Using wodSSH is easily - just put it on your form, set Protocol type and issue Connect method - and just wait for things to happen.
When in secure mode - you can connect to SSH servers, which are standard today in remote console communication. wodSSH is able to automatically determine if remote server is based on SSH1 or SSH2 protocol version, and communicate accordingly. It will provide you with information about remote server Fingerprint, so you can always get authenticated information about remote server.

wodSSH can be used as scripting client. Easily, you can set it up to connect to server, execute one or more commands, wait for response, and just disconnect. And all of it fully automated. It also supports blocking and non-blocking operations, thus it's suitable for many environments, such as ASP. Using WaitFor and Execute methods, it will behave just like expect command known from UNIX systems.

When you're unsure when to send actual command, wodSSH may help also. Using it's unique Prompt property, it can fire event for you whenever remote server sent command prompt to enter new command. All you have to do is send new command once this event is fired.
