A sign of a vibrant developer community is the active blogosphere that surrounds a technology. Here's a more or less random selection of what's being talked about this month in the PowerBuilder community's blogs.

Specifying Null Values as Retrieval Arguments in the DataWindow Painter
by Dave Fish
from http://powerbuilderevangelist.blogspot.com
Some of you have been asking for this enhancement for a long time now. Well, it's finally here (in version 11.1). You can now have a null value for a retrieval argument in the DataWindow painter.
Just tick the Null check box for any argument where you want the value to be null. If you type in a value, the check box will be cleared.
This enhancement and several others in PowerBuilder 11 came through the ISUG enhancement request system. Anyone can enter an enhancement request, but only ISUG members can vote. ISUG Memberships are available for as little as U.S. $20, so check it out (www.isug.com/common/EnhancementsProcess.html).
