Tcl 8.6 shipped with the Tcl Database Connectivity (TDBC) API for accessing
disparate SQL database implementations in a standard manner. I happened
to need it for the first time recently and collected my notes
into an introductory article
for the benefit of those who, like me, prefer to be spoon fed.
There is no shortage of hotkey programs for Windows, many of them of high
quality. And of course Windows itself allows you to define hotkeys.
However, a hotkey program in Tcl is not only very simple to write,
it offers the full flexibility and power of Tcl
behind it. Meaning what exactly? Read on.
There are times during software development when you want to run
in interactive mode with
maximum privileges on a system, be God as it were. One might think
running as Administrator would do it but it doesn't.
To be truly omnipotent
on Windows, you have to run under the LocalSystem
It is easy enough with Tcl and this post shows you how.
As a side bonus, it also describes how to inject processes into the interactive
user's desktop to run under the user's account as well.
One of the strengths of Tcl
is the ease of integration with other software, whether they
be COM components, libraries or even executable programs that
are not designed for interaction with other programs. Here we look
the facilities Tcl offers related to the last of these --
running external programs and optionally
interacting with them using standard I/O mechanisms.
This post may be partially, or even completely, out of date. Both
OpenSSL and the TLS extension have had major updates since it was written.
Building the Tcl TLS extension on Unix/Linux is straightforward
because OpenSSL libraries are already present and installed. It's a
different matter on Windows where you need to build OpenSSL yourself.
This short article describes the process.
As for many pieces of software, one of the issues in testing
TWAPI is the number of different platform
configurations under which the test suites need to be run. Manual
configuration is tedious and error-prone so automation of the process
using VMware and the vix package is a big win.
