Set value to single view on specific TabStripViewPager panel
On a TabStripViewPager with more than 1 loaded layout the views defined in Sub Global are only valid for the last loaded panel. Change of values on previous loaded panels require some extra effort. With this code you can access a specific view on any tabstrip control panel by using Erel''s RemovePage function.

Example of #Extends in Service
Starting from B4A v6.50 services support the #Extends attribute. This is useful for libraries that need to extend a service. The previous solution was to communicate with a B4A service with a specific name. This was more cumbersome and limited. The #Extends attribute allows the B4A service to directly extend the library service.

Version safe themes
Update: If you are using B4A v8.0+ then you should just add: CreateResourceFromFile(Macro, Themes.DarkTheme) ''or Themes.LightTheme Older versions: If you are not explicitly setting the theme in the manifest editor then it will change based on the device version and targetSdkVersion value. Assuming that targetSdkVersion is set to 26 (as soon required by Google) then the theme used by default will be: Device version Android 2.x - Always the old Android 2.x theme Android 4.x - Theme.Holo (dark background) Android 5.x - 6.x - Theme.Material (dark background) Android 7.x+ - Theme.Material.Light.DarkActionBar (light background) This behavior can be problematic. In most cases it is better to explicitly set the theme. The correct way to set it is with manifest code

Password generator Sub
I needed to generate passwords in my app, so I wrote the code below, but calling the sub with strings, like "(6, "NUMBERS")", or "(8, "NUMBERS_UPPERCASE_SYMBOLS")". When I was going to share the code here as a snippet I saw this thread, and then I took the idea of calling the sub with arguments (True, True, False, False), instead of using a string. So, although the library exists, perhaps someone prefers or finds easier to use a Sub, or wants to customize the characters to use (to avoid similar characters, like "I1", "O0", for example).

How to add a custom sound from File.DirAssets [Notification Builder]
I want to share with you my solution, using the Notification Builder (Thanks to @barx for this awesome library <3 ), to play a custom sound from your DirAssets folder. I did it because this method use the notification volume for this sound (instead of the Soundpool solution, that use the media volume).

Sending email via SMTP with POP before SMTP
The emailing (via SMTP) trouble is solved: to avoid server auth error before using SMTP server we have to check email, say by POP3. This class is tested during 3 days on popular app with around 70-80 emails from an app to the chosen GMAIL box to self. No sending errors now. Before there were 2-3 sending errors per day.
