The SocketTools .NET Edition includes the InternetServer class that was designed to simplify the implementation of a TCP/IP server application. With only a few lines of code, you can create the framework for a multi-threaded server that is completely event driven. You only need to create event handlers and then write your server code to respond to those […]

SocketTools provides both 32-bit and 64-bit components and libraries for the Windows platform. Although most applications today continue to be 32-bit, there is no question that 64-bit platforms are growing along with demand for native 64-bit applications. It’s estimated that over 90% of Windows 10 desktop installations are the 64-bit version, and virtually all desktop and laptop PCs have 64-bit processors.

One of the errors that developers occasionally ask about is the "Handle not owned by the current thread error"; what it actually means and the situations in which it can occur. This doesn't tend to be an error message that developers using the SocketTools ActiveX controls encounter. It is almost exclusively an issue related to

SocketTools includes components for sending e-mail using SMTP, downloading and managing messages using POP3 or IMAP4 and a general purpose MIME component that can be used to parse messages and create new ones. However, one of the problems that developers often face is what to actually do with those messages once they have been sent

In older versions of Windows, it was common for regular users to run with administrative privileges. In fact, most Windows applications made the assumption that the user was a member of the Administrators group and therefore had unrestricted access to the entire system. This has changed with the User Account Control (UAC) system, which limits access to critical system resources,

The Secure Shell protocol provides a secure, encrypted connection between the local host and a remote computer, ensuring that third-parties cannot decipher any intercepted network traffic. Originally SSH was used primarily on UNIX based systems as a secure alternative to the insecure TELNET protocol, in which private information such as passwords would be sent as

SocketTools provides methods that allow an application to verify that the contents of a file on the local system are the same as a file on the server. This can be used to either ensure that a file was uploaded correctly, or to check whether or not a file should be downloaded. For example, an application could check

SocketTools includes a component that makes it simple to access news feeds that use RSS. Really Simple Syndication (RSS) is a collection of standardized formats that are used to publish information about content that is frequently changed. A news feed is published in XML format, which contains one or more items that includes summary text, hyperlinks to

One typical requirement for many applications today is the ability to transfer files between the local system and a remote server, and the File Transfer Protocol (FTP) and Hyptertext Transfer Protocol (HTTP) are the two most commonly used Internet protocols for this purpose. SocketTools has components that support both of these protocols, making it a

When people think of the Secure Shell (SSH) protocol, interactive terminal sessions and secure file transfers using SFTP are typically what to come to mind. In addition to these common functions, SSH also supports securely executing a command on a remote host and returning the output of that command back to the local system. The
