How to detect the end of a parsed XML file?

Hi guys,

I am stumbled on this silly issue...

I am parsing a XML file and it's working fine. However I would like to perform an action after the file has been completely parsed by XMLSax (1.11).

Is there a way to detect when the parsing ends?

Thanks!

Arranging the .txt file

Hi,

I have this saved .txt file in my app where it will record down the datas when I click save. However, the .txt file shows it in an arrangement like this:

0
1
2
3

I would like it to be like this:
0 1 2 3

It would be better if I can add in coma in between as well. How do I arrange it that way?

'In AppStart:
Dim x = Rnd(0,2) As Int
If x = 0 Then

End If

event auto-suggest should include events from classes in project

I just added an event to a class module, but when I go back to write an event listenener, and type "sub" then space then tab (to trigger the event auto-complete), the list does not include the event I defined in my class module.

I'm assuming that the event list only shows events from libraries?

Is it possible to include events from classes used in the project? Or did I miss something?

How to destroy a B4X object?

To protect my B4J web socket server, in some cases I want to destroy "web socket handler instances" automatically created when a user connects to my b4j web socket server.

Actually, we (or at least I) do not know how to destroy any object in B4X.
Using VB.Net (or C#) you can use the method Dispose; with B4X?

I have not found documentation in this regard, on site.

B4A v6.0 (which was not yet released) adds support for runtime permissions. The nice thing about runtime permissions is that the user is not asked for any permission when they install your application from Google Play. Instead they will be asked to approve...

Iconify (Button, Label, Togglebutton, Toast with IconFont Icons)

This is a wrap for this Github Project: Iconify2
It is basically the same as my wrap for the IconicFontEngine but it has some cool advantages.

More exactly this wrap is a mix out of Iconify2 and PrettyToast in one Library.

Note that you need B4A 6+ to use the Library as the...
