PowerBuilder – Fontheight method in Expressions
An enhancement was put into PB12.1 dealing with determining the height of a datawindow column based on its font setting. It’s called Fontheight and takes a string parameter. Unfortunately there does not appear to be any documentation on it in the PB help files (I’m looking in PB12.5). You can see a reference to it…

Windows Installer Error – “Installshield error 1500”
So I finally upgraded my laptop to Windows 7 from (shudder) Vista. Not a big deal, just pop in a new hard drive (four times larger than old one). Boot from the install CD and go to town. After the os install, now all the other Microsoft products (Visual Studio, SQL Server, Service Packs, etc.).…

PowerBuilder – Finding special folders – FDCC Compliance
Here is a link to an article by Bruce Armstrong (since broken) relating to new functionality in PB11.5. The article specifically deals with FDCC (Federal Desktop Core Configuration) Compliance in PB apps and specifically the SHGetFolderPath Windows API function.

PowerBuilder – Where is Autoscript?
The autoscript feature in Powerbuilder is something I’ve come to rely on quite heavily, especially when dealing with user objects and such which you may be unfamiliar with (…do I pass two ints and a string or two strings and an int?). However, it is a feature which can frustrate you in just trying to…
PowerBuilder – More Datawindow Mouseover Effects
So I download the latest Chrome browser beta the other day (v17) and I notice a neat effect on the tabs prior to applying my custom settings. A gradient centered on my mouse pointer passed across the tab as I moved it. It was very subtile but noticiable if you were paying attention. Naturally I…
