What's New - June, 2011
[Home]
June 6, 2011: Program production has slowed the past few weeks. I blame graduations, some nice summer weather (finally), upgrading the wife's computer from XP to Windows 7, and the 7-year-old germ carrying grandson who put us both under the weather for a few days.
Here is a Delphi Techniques program which might be useful to me and hopefully to others in the future: OnIdleExit Demo demonstrates the technique for performing background calculations in your Delphi programs without impacting the user's ability to interact with the program.
June 12, 2011: Version 2.3 of our Print Preview Demo program in the Delphi techniques was updated to improve margin handling again. There are subtle differences in the way that the non-printable area around the edges of paper are treated relative to displaying an accurate preview image on a screen. Maybe I have it right this time.
June 17, 2011: Lessons learned from last week's OnIdleExit Demo was put to good use this week with Version 2 of Spellbound which adds user play to the original program search code. Spellbound V2 asks you to find as many words of a given length as you can from a given set of letters. In this version the program does its search in the background, usually completing in about the time it will take you to find and enter your first word. Spellbound runs a standalone program or as a selection from our Wordstuff3 set of word oriented programs.
June 28, 2011: Another Delphi Techniques entry
today. TPageControl is a Delphi component that displays and controls
multiple tabbed pages,
PageControlColorsDemo illustrates how to add colored background to the
individual pages and how to use color, font, or graphics on the tabs to show
which one is currently selected. Oh, and how to draw a simple
"Smiley"
