Excerpt of article text...
One of the features introduced in RB 5.5 is the InterProcess Communication Socket, aka the IPC Socket. Originally a Unix feature, it is now also available on Windows, which makes it a good cross-platform solution. IPC sockets are also faster than normal sockets -- slightly on Unix systems and quite a bit on Windows, at least according to RS engineers. In this column, we will see how to put these sockets to good use: we will build a minimal GUI framework for Python scripts, using IPC sockets as the communication medium. While you may not, dear reader, care for Python -- just don't mention it to me -- the example developed here will still provide you with the basics necessary to write your own communication framework.
Objectives
We will build a communication framework ("physical" connection and vocabulary) between a REALbasic application (also named "the framework") and a foreign application (here in Python, just to show that IPCSocket is not restricted to RB apps), with the framework providing GUI services to the faceless application (the Python script).
