You're welcome sir! :)

Hello Donald,

Yes; certain controls base their functionallity in Array variables. This is good, because, we can creates Array variables too, and uses all the Arrays related actions for both control's Array variables and our own Array variables.

For example, if we are talking about Select controls, we always can get the currently selected item using a code like this:

The first argument is the Array from we want to get an specific item. In this case such Array is the Select control "Items" Array, but remember we can use this same action with any Array variable.

The second argument is the "index" we want to get from the Array. The Arrays stores the items in a zero based index, so the first item is the "0" (zero), the second item is the "1", and so on. The Select controls offer to us the "ItemIndex" variable, which stores the currently selected item in the control.

The third argument is the result variable, that is, the variable which stores the item we get from the specified Array.

Above we say the Select's "ItemIndex" stores the currently selected item in the control, and, we also can write this variable in order to select an item programatically, just by using the SetVar action:

The above action establish the first item in the Array (zero indexed, remember) as the selected item in the Select control.

As I said above, we can play with all the Arrays related actions, so, for example, we can add a new item at the end of a Select control:

We can add a new item at the start of a Select control:

We can concat a "Select2" control items into a "Select1" control items:

We can remove the last element form of a Select control:

Or remove the first element:

And finally we can continue using the other Array related actions to reverse the items, short them in various ways, search for items, etc., etc. You can start with the NewArray action in the help file and continue scrolling down for other Arrays related actions.

If you have any further question just post it Donald. :)

Hello,

Hi,
Will this logic work with audio file?

Yes, edunt. In principle, the HTMLContent control can contains any HTML and app variables.

Hello Donald,

The HtmlContent control is a bit special, since we can't access their HTML variable in runtime. In fact probably we can do it using Javascript, however, such variable is plained to used at designtime, commonly to put inside one or more variables. Then this variables are parsed in compile time and therefore become available at runtime.

Therefore, probably what you can do is to think about variables, because variables can be changed at runtime. Then, for example, if you shown an image in your HTMLContent control using a code similar to this:

In the app's view Show event we can set the variable to this:

And then, in every other place (a Push Button's Click event, for example) we can place another similar code:

Also, we can made the entire HTMLContent control a variable, that is, we can simply place inside something like "[MyVariable]", then we can change the content of that variable at runtime.

Hope this can help you in some manner Donald. :)

Always thanks you Donald. :)

Hello Donald,

One possible way (if you have the very latest release of App Builder published right now) is to use the "TextAlign" CSS property of the Label control. In the object inspector, you can view a "TextAlign" property in the "Normal", "Hover" and "Focus" tab. Just choose one of the available values for this property like "center", "right", etc.

Another possible way to align the Label can be using their "Classes" variable. In that variable we can put the value "text-center" or "text-right". These CSS clases are provided by Bootstrap CSS and has available from us.

Another possible way is to use the app's "Inlince CSS". Access to that from the app's options dialog or from the designer object inspector. In the CSS editor, write something like the below code, suposing your Label name is "Label1", change the identifier for your Label's name.

The above code center the label.

The above code align the label to the right. Other possible values for "text-align" can be found here. This way can be useful, because we can use media queries, for example:

The above code means "If the browser window is smaller than 500px, put the 'Label1' to the right".

Finally, we can also use some actions to change the Label's alignment programatically, for example:

Hope this can help you Donald. If you have any further question don't hesitate to post it.

Hello,

I was away little bit from the forum because we just got a new baby girl.

Don't worry, and congratulations edunt! :)

Hello,

A sample application can be good. Anyway, remember App Builder include a Chart and a Gauge control. Maybe not too complete like the library you linked, but, they works out of the box. Anyway thanks for the link edunt.

Hello,

I also note such behaviour using Apache Cordova. Certainly I think it's a problem in Apache Cordova I need to investigate too. If your target is the Firefox OS, for example, you can use the webapp option of App Builder, not the Cordova one. App Builder generates for you the appropiate manifest file, preparethe right icon and finally you can use the Zipper tool to get a valid Zip file to be uploaded into the Firefox Marketplace, just like the Calculator sample app.

P.S. Yes; of course if you need certain Apache Cordova stuff, then before the problem with Cordova must be solved, but I am not completely sure, since I am not try to upload (and corrupted?) Zip file.

Hello Donald,

Sorry the delay, I expend the day in the hospital with my mom. Certainly there is no option currently to made an image "fixed", that is, if you choose the "scaled" app's option, then all the control try to scale, also the Image controls. Currently the only way to maintain the image in a fixed size is to avoid the "scaled" app's option, or, may we can use it, and then, un runtime, use certain CSS classes or actions like "SetStyle" in order to maintain the size of our Image controls or may provide it with a more appropiate images for larger screens, for example. About the zoom feature, yes, it's the application who have an option like that, not the current Image controls.

Hola pesadillo,

No estoy muy seguro de hasta qué punto es el cliente el responsable del comportamiento que describe, puesto que también el servidor tiene algo que decir ahí, por no hablar ya del propio sistema operativo del teléfono en cuestión.

Si le he entendido bien, lo que quiere es, precisamente, que siempre se muestre "actualizado" (hasta donde el servidor entienda) el contenido de los "Iframes". Si esto es así, tal vez pueda usar un sencillo truco.

Se trata de asignar al "Iframe" una URL que ha de ser única, de modo que el servidor, así como el sistema operativo (si este tiene algo que ver) no la guarden los datos en caché alguno. Dicho truco puede resumirse así:

Como ve, primero obtenemos un núero del 100 al 9999 (podría variar, podríamos poner otros datos...) y después preparamos dicho número para ser añadido en una URL. A continuación asignamos la URL del "Iframe1", añadiendo el argumento "r" cuyo valor es el número aleatorio anterior.

Ojalá esta información pueda serle de ayuda.

Hello,

In my opinion the point is that build an application two times is more expensive than build the application one time. Not too much words to said, except that, since we need the release build ONLY when we are ready to upload the application into the Google Play Store, I think build an application's release everytime is a waste of time and resources.

Do you really thing we need both debug and release APKs during the application's development?

Hello,

Why build a debug and a release versions if we only need one of them? For that reason I separate the build in two files, one for debug, one for release. Maybe another approach can be taken, but build the application twice can be a waste of time, specially the first time we build an application.

Hola,

Me alegro de que al final diese con ello. Gracias por indicar la solución para su servidor.

Hola PoKeRGT,

Es raro que no pueda configurar los permisos CORS de alguna forma: al fin y al cabo se trata de un estándar que debería estar soportado por todos los servidores, so pena de dejar de dar servicio cuando se requiera. En los ejemplos de App Builder se habilita CORS usando PHP, pero, me consta que podría hacerse usando archivos ".htaccess" de Apache, por ejemplo.

En todo caso, le recuerdo que, para mostrar imágenes, no necesita usar un control "HttpClient", sino que basta con usar el control "Image", por ejemplo. De nuevo le remito a los ejemplos del programa, puesto que en muchos de ellos se hace uso del control "Image". En todo caso gracias por su interés en App Builder.
