Handling Null Dates with Date Selectors

CategorycalendardateExt JSnull dateTip of the MonthValence

When working with dates on IBM i you will often need to deal with null date values of 0001-01-01.  Depending on the display format you’ve chosen, in a Valence UI designed with Ext JS a null date field will be rendered like this: date_picker_1 When the user clicks on the date selector trigger here, a calendar pops up based on the year and month specified in the field.

Styling .xlsx Spreadsheet Cells in Valence 4.2

CategoryExt JSTip of the MonthValenceVVOUTXLSX

The VVOUT spreadsheet procedures were enhanced in Valence 4.2 to support the generation of Excel spreadsheets in .xlsx format.  You can see a practical example of these procedures in action by clicking on the download button on any of the entities in the Portal Admin app (the corresponding backend RPG code is located in various VVADM*** source members). The procedure for applying styling to cells in these .xlsx-based spreadsheets is a bit different from the old .xls formatting used in prior versions of Valence.

You already know that installing Valence on IBM i and using it internally within your corporate network is fast and easy.  Your company’s employees should also be able to access your Valence instances through a standard VPN connection when they are located outside of your company’s physical network.  But what about when you need to provide secure access to Valence apps to the outside world directly through the Internet?

Using a Dynamically Set App Path

CategoryTip of the MonthValence

Normally the paths associated with Valence apps are hard-coded to specific values that never change. The users clicks on the app and the Valence Portal directs them to a specific IFS path or web page. But what if you had a special use case where you wanted to alter the IFS path or URL based on who is logged in, or depending on which environment they're using? This can be done using a special exit program technique that will dynamically alter the path of an app upon being launched from the Valence Portal.

Creating a JSON Web Service in Valence

REST-based web service, with the other end being the "consumer" of said service. Consider this scenario:  You want to give a VIP customer the ability to have their system automatically contact your system to obtain real-time shipment status updates for specific orders being fulfilled by your company.  And as luck would have it, you've already done the legwork to creat an order inquiry Valence app on your system, complete with an RPG program that provides the necessary data for these shipments in JSON format.

Making a Valence Portal app tab "sticky"

CategoryTip of the MonthValence

As you create and deploy more Valence apps within your organization, logging in to the Valence Portal becomes more of a daily routine for your IBM i users. In such cases, setting up a global auto-start tab (as done in Portal Admin > Settings > Session Options > Application to autostart) can be a handy way to convey daily news, bulletins and announcements to the office staff. This tip shows how to make that launched tab "stick" so that it's always open. You could also apply this concept to any other apps that are launched in the Valence Portal.

Using your own PC as a test machine for Valence apps

CategoryTip of the MonthValence

Ever wished you could save and test your front-end development work locally, on your own PC or laptop, then push it to your IBM i only when it's ready for user testing or production? Turns out this is indeed something you can do! Using this process, the changes you make during development are completely local to your PC, thereby not affecting any deployed Valence app in the interim.

Building a Bridge Between Your 5250 Programs and Valence Apps

CategoryIBM iPressTip of the MonthValence

Old UI habits die hard!  You may have developed some of the most beautifully functional and user-friendly Valence apps for your company, but the green screen legacy can still be hard to overcome. So long as your company's operations require at least some 5250 programs to be used -- as is typical for IBM i sites that have been around for a while -- then persuading users to flip from Client Access over to their web browser to do, say, a quick inventory or order look-up in Valence may pose a challenge.

When One App Talks to Another, Good Things Happen!

CategoryIBM iTip of the MonthValence

As your repository of Valence apps grows, you may soon find occasion where you'd like to “spawn” one app from another in the Valence Portal. For example, you may have a simple inventory lookup app that you could launch whenever someone clicks on a line on a customer order, passing in the corresponding product number so the user doesn’t have to re-enter it manually. That same inventory lookup app could also be launched when clicking on an item in, say, a purchase order app. And so on. This kind of functionality inter-app functionality can serve as a great convenience your users.
