Using serverStorage to save data on the Volt Server

AppStudio 6.1 brings a new Volt feature: serverStorage. It lets you save and retrieve data on the Volt server. Here are a few uses:

  • As a backup: Keep critical data in the server, so if the phone gets lost or damaged, information is not lost.
  • Multiple devices: If the user runs your app on multiple devices (desktop included), your app can pick up where it left off with the same data.
  • Support: As the owner of the app, you can examine what is in your user’s serverStorage.
  • Data Sharing: The owner of the app can read and write to users’ serverStorage using a different app. Use this to send specific information to users, or to get data the user has collected.

It’s easy to use. You save and retrieve values using a named key. The values can be of any data type: numbers, strings, arrays or objects. There are no limits on the number of values you keep, nor how big the values can be, other than that they be reasonable. If you need to use a lot of data, check with us at support. Here are some examples:

The manifestFile property and online apps

In Project Properties, there is a property named ‘manifestFile’. The setting of this property can have a big effect on how your app works, online and offline.

The default setting is appcache. This causes AppStudio to collect the names of the files in your project and put them in a special file called OfflineApp.appcache. When your app is downloaded to a device, this file is checked by the browser. The files named are stored in the browser’s persistent storage on the device. This allows your app to run even without an internet connection, since all the files needed are present.

Each time a cached app is started, the browser checks to see if the OfflineApp.appcache file has been updated on the server: if so, the new version of the app is downloaded. If it can’t reach the server (perhaps because the device is offline), it does nothing and runs normally.

If the OfflineApp.appcache file has been deleted on the server, the app is deleted from the device.

The manifestFile property can also be set to no caching. The OfflineApp.appcache file won’t be created, and the app will not work in offline mode. It’s worth doing if your app will only work if the device is online: for example, if it has a lot of Ajax calls which are necessary for operation. A side benefit is that you won’t get any “Cache Error” messages.

If you change an app from appcache to no caching, be sure to clear your browser’s cache. Otherwise, it will still think it’s a cached app.

The final choice for this setting is manifest. It’s an obsolete setting. When the standard was first set, it specified .manifest as the ending for the file. Microsoft pointed out that it already was using .manifest for something else. Oops. The standard was revised to call it .appcache instead. Some early AppStudio projects were created in the .manifest days – changing the file suffix now could cause cache errors.

Positioning Controls (II)

In our last post on positioning, we discussed the different ways of arranging controls on a form. This time, we’re going to have a closer look at static positioning and how you can get your controls to the proper place on your form.

You might want to open a new project in AppStudio and play along. Start a new form with position set to static. Add three Bootstrap buttons:

Notice how they position themselves? They automatically go to the left side of the screen, below the previous button. Let’s see what ways we have to put them on the same line.

Using Adsense with Volt

search-1Adsense is Google’s web ad service. If you agree to display Google’s ads on your site, you’ll collect money each time someone clicks on an add.

To do so, add the AdSense control to your app. Choose the size (320×50 up to 300×250) and position it. AdSense will automatically display ads in the space. You’ll need to set Client number and Adsense slot number.

Get the Client and slot numbers from Google Adsense when you sign up. Follow Google’s instructions for the rest: they are pretty good.

One of the requirements is to list the name of the site your app is hosted on. If you don’t have a site, no problem. You can use Volt. Simply supply the URL to your app on Volt:

screen-shot-2016-11-21-at-3-52-32-pm

Here’s an ad in an app:

screen-shot-2016-11-22-at-5-10-10-am

And here’s a link you can try yourself: https://adsense-wets-correctly.volt.live/

Now tell people about your app and watch the money roll in!
