SSH & Telnet client

In my previous post I created a very basic telnet only application. So in order to add some new features to the application I will be using the ExtraPutty library.

We need to leverage the ExtraPuTTY.dll in order to use it’s functions in C#. So because ExtraPuTTY.dll is not a COM .dll we can use the DllImport attribute to call the functions within the library.

Calling the methods from ExtraPuTTY.dll

You can use dependency walker to take a closer look at the methods within a .dll file. This is especially useful when you’re building a program and want to see the capabilities of the library you are using.

Dependency Walker is a free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.)
