Windows 7 ‘Gotcha’ – PowerBuilder Application Control Fonts Too Large

Posted on February 21, 2013 at 7:17 am in

So I finally got my computer upgraded to Windows 7 at work.  I was very happy to have it since XP was really starting to annoy me and I couldn’t really do some of the development tasks I needed to get done. After a week or so I started looking through the applications I work…

PowerBuilder – Update the Datawindow object definition programatically

Posted on October 11, 2012 at 6:31 pm in

I’m doing some work on an application to aid in the mass update of various datawindow attributes. It’s not rocket science since you are dealing with a series of text files and doing some basic ‘find and replace’ operations. However, if you have ever worked on a project which has been around for a while…

PowerBuilder – The RAD tool on the Edge of Forever

Posted on September 18, 2012 at 9:05 am in

I’ve often considered the significance of this graphic on the Welcome screen in PowerBuilder. However, it’s quickly forgotten since I only see it if I am installing the software for the first time on a new machine (I deselect the option to show it when PB starts).

This is more of a database driver error but I encountered it within a datawindow I was working on so PB gets credit. I was working on a generic data drill down control which has a filtering process to eliminate data based on a date argument. Since I also wanted this date value for other…

PowerBuilder ‘Gotcha’ – Strings, Describe and Position Attributes

Posted on September 6, 2012 at 6:40 pm in

So I’m getting the position attributes of a column in a datawindow to aid in the display of another visual object. What I initially coded was this: ll_open_x = Long(adw.describe(as_colname + ‘.X’) + & adw.describe(as_colname + ‘.height’)) + 10 I run the window and my visual object is no where to be seen. Looking in…
