Allowing multiple selections on a combo box filter

CategoryTip of the Month

Imagine going to a buffet and being told you can only choose ONE item for your plate, and if you wanted more you'd first need to take that single-item plate back to your table, consume it, then return for the next item.  Wouldn't it be great if you could just load up your plate with two, three, four items or more and consume them all at once?  


Using an Exit Program with VVMAIL

CategoryTip of the Month

If you're creating NAB forms or custom apps that send emails using the VVMAIL service program module, as demonstrated in the "Send Email" utility nested inside the Examples app, you can set up a back-end routine to globally intercept all outbound messages using an exit program. The exit program you create can be used to override the mechanism through which emails are sent, or to store pertinent details in a custom "outbound email log" for auditing purposes. 


Quickly create a file upload app

Even as companies move toward a more paperless workplace, printed documents and paperwork remain an inevitable part of doing business. Whether it be a supplier invoice, a bill of lading, a certificate of quality, a signed contract, a proof-of-delivery or what-have-you, many business transactions are still supplemented with a piece of paper somewhere.


Add intuitive action buttons to your grid rows

CategoryTip of the Month

If a picture is worth a thousand words, how much more valuable is a button with an icon on it, compared to a string of words nested inside a row menu?  While a thousand times valuation differential may be a stretch, there's no doubt that a visible action button on a grid row is going to be considerably more intuitive to users, particularly new users who are exploring apps for the first time.  Such buttons also offer the added value of requiring one less click to trigger a row action.


Best Practices for Managing your Valence Instances

CategoryTip of the Month

With the end of the year approaching, most companies find they have a rare opportunity to do some significant system maintenance as users go offline for the holidays.  In addition to, say, upgrading to IBM i OS 7.4, this may also be a good opportunity to rearrange your Valence setup so it's following a "best practice" configuration.  In a proper setup you can download and test new Valence builds without affecting any of your production or test instances.

Introducing Valence Fusion5250 - Integrating Green Screen with Web

Since its introduction in 2008, Valence has helped countless IBM i developers create top-notch web and mobile apps using some of the slickest UI technology available.  As the customer base grew, CNX introduced a number of additional development tools to Valence, including AutoCode and App Builder, to make the process of creating and deploying apps as easy as possible. 


Convert your RPG-based reports into web apps

CategoryTip of the Month


If your company's ERP system dates back to the AS/400 glory days, your users are likely accustomed to running programs that generate "old school" spool file output.  While working with printed reports was quite common in the past, today most users prefer to work in a more paperless fashion, opting for on-screen apps or downloaded spreadsheets wherever possible.

Showcase Your Key Business Metrics Through a Kiosk-Style App

With the advent of low-cost "Smart TV" units — flat screen monitors with integrated web browsing capability — it's easier than ever (and cheaper) to adorn your company's front lobby, cafeteria, shop floor or other high-traffic areas with automatically-updating displays that depict important business metrics in real time.  Using these TVs, or even "dumb" monitors attached to low-end PCs, key stats like sales numbers, inventory levels, picking performance, etc. can be shown to employees and guests without the old-school hassle of printing and replacing paper displays.

IBM i Developers: It's a Great Time to Embrace Low-Code App Builders

Recently I've had some fascinating conversations with people regarding Nitro App Builder, the low-code app builder included with Valence.  In case you've never heard of it before, Nitro App Builder is a tool that's quickly taking over as the development method of choice for many apps that would have been coded manually in Valence just a year or two ago.  It creates really useful apps by configuring them interactively, with little or no programming required.

The Wild Evolution of AS/400 to IBM i

CategoryIBM iAS/400Valence

With IBM i turning 30 I thought it would be fun to recap the evolution of this amazing operating system over the years from my perspective. The first system I ever worked on was a model B50 way back in 1991, and of course it was called AS/400 at the time. I thought the machine was pure magic with its tan towers and reel-to-reel tape drive (some of you may have to look that up).

CNX Turns 22 Today!

CategoryValencePRMSBPCSAS/400IBM i

Twenty-two years ago today we officially registered CNX as an Illinois corporation (wow, that's a shocking thing for us to write), so we thought it might be fun to take a short trip down memory lane on this blog post.  So much has transpired in those years that we could write a book, so we will necessarily need to keep it brief here — perhaps one of us will write that book later!  

Anyway here it goes:
