Display Charts on a Large Screen

[gwilburn]

I'm trying to display a NAB Chart application on a screen in our warehouses. The app has several chart widgets.
I want to:
1. Have a simple URL to hit the screen without a login prompt, and
2. Have the all the screens refresh every 5 minutes

I was able to get the app opening using a URL shortcut:
https://oursystemname:8060/build/production/Runner/index.html?autoLogout=false&app=1042&autoLock=true &portal=false&user=valenceuser&password=goofypassw ord

I created the user/password in Valence Admin - I'm good with it showing in the URL if this doesn't pose a security risk. I can't quite follow the documentation on calling VVLOGIN to create a session ID to use instead of the user/password. Where would this take place?

Secondly, I know a refresh interval can be set at the widget level. But is there a way to set an app-level auto refresh interval? Script?

TIA,
Greg

Hi Greg,

If you're attempting to create a session ID on-the-fly, you could make a call to VVLOGIN in a separate program, then use the "customSid" token it returns in your URL, as described in Method 2 here:

This might be more trouble than it's worth if you already have a URL with an embedded, low-authority user/password that's getting you what you need.


To mass-set the refresh interval on every widget in your app, you could try this:

• Create a single app variable named "reloadWidgets" or similar.
• Link the "refresh" property of each widget to this app variable.
• Place the following in Behaviors > Startup > Execute Script:

[COLOR=#222222][FONT=Arial][FONT=monospace]setInterval(function() {
setAppVar('reloadWidgets', true);
}, 90 * 1000); // 90 seconds in milliseconds

success();[/FONT][/FONT][/COLOR]

Thanks Rob!

I guess the piece I'm missing is how to invoke the program call to generate the customSid value, then get that into the URL.
The PC that drives our screens simply load the browser at startup with the predetermined URL.

I'm good with having the user/password in the URL since we can create a low-authority user in the Valence portal that is not an IBM i user. It can't be used to log on to the IBM i.

This is EXCELLENT!

So I had some trouble with the above suggestion. After some period of time, the screen would revert to a Valence login. This was SOMETIMES the "lock" screen.

My URL is

https://tbfpwr9.totalbiz.local:8060/build/production/Runner/index.html?[B]autoLogout=false[/B]&app=1076&user=myuser &password=mypassword&autoLock=true&portal=false

I cleared the browser cache, but that didn't seem to help.

So I changed my script to also reload the entire app every hour.

// Refresh the Widgets every 2 minutes
setInterval(function() {
setAppVar('reloadAll', true);
}, 120 * 1000); // 2 minutes in milliseconds

// Reload the App/Screen every 60 minutes
setInterval(function() {
location.reload();
}, 3600 * 1000); // 60 minutes in milliseconds
success();
