For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
When to use Frames

Frames are an HTML feature that people seem to love or hate. They do provide an extra power to how information can be navigated on a web page by allowing partial page refreshes and partial page scrolls BUT there are a number of things on the "downside" too. Gary White will tell you all about the downside on his "rant" page.

I'm not a great fan of frames and you'll find that we don't use them on our main web site nor on most of the addition sites and client sites, but they do have their uses. Indeed - the subject has come up twice in the past two days with two different customers ... the general consensus is "best not used in most cases, but there are a few occasions".

Coding of frames is non-trivial and testing needs to be carefully and thoroughly done over a number of browsers. So I have written a PHP example where Frames ARE useful ..
* A file selector window on the left of the screen
* A feedback window on the right of the screen
* Upper and lower frames to give instructions and extra buttons
