Matt Balent will be blogging about PowerBuilder for 100 days! Over those 'few' days he'll be looking at 'a series of discussions focused on basic PowerBuilder development. Note: These articles are written with examples created in PowerBuilder version 12.5.' He's two days into the blog and he's already covered Creating a Workspace on Day 1 and Creating a Main Application Window on Day 2. We'll be following he's exploits closely!

Many PowerBuilder developers are ISVs as well. Sybase recently published an interesting article about ISVs and in particular their relationship to the Cloud. About how hosting can be difficult for an ISV with limited resources:
- They must anticipate what customers will want and try to accommodate as many of these options as possible. Narrow solutions yield limited revenue.
- They must be prepared to accommodate special changes and customization, especially from high-value accounts.
- Because solutions frequently transact data from many different customers (and those customers are often close competitors), ISVs must pay extra heed to security to vouchsafe data seclusion.
- They must be sure that the technologies they use will be relevant and supportable indefinitely.
Different solutions exist for these problems, ISVs can turn to others in the community for products like Visual Guard for security and Customization Studio to tailor their product. Using known products, reduces the risk that ISVs will have to "back pedal their technology choices. A full rewrite of any customer-facing software system means taking their foot off the gas, the impact of which goes straight to the bottom line.
"I just stumbled on a neat new feature in the datawindow painter, specifically on the background tab of a column. The Gradient stuff was added in 10.5 (I believe) and now you can actually see the numeric value of the slider bar without having to pick through the source."

"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 noticeable if you were paying attention. Naturally I wanted to reproduce the effect in Powerbuilder (I used v12.5 but you could do the same thing in 10 or 11)."

This French blog entry goes over the basics of colours in PowerBuilder. The code is pretty comprehensible even if you're not a francophone!

"You get a call from customer support regarding a client who is reporting that the tab labels are all ?grayed out' on a particular window. You get a screen shot and see that, yes, they are. These tabs have been disabled within the application by various other processes."
