<PEDANT WARNING !> 'Cast' not 'Casted' for 'can be ...' Erels's English has improved leaps and bounds since I first 'knew' him back in 2007 but he still slips up occasionally which is why I'm here to help 😁 </PEDANT WARNING !>

It's done as an easy way to reset the printer to a default state so that any setup done for the previous demo/test will be reset for the next one.

If you mean the link Download the latest version (1.12) in the first post then it has just worked fine for me though you may get a security warning - ignore it and keep the file.

Do you want the users to be able to write some code? There's a Basic interpreter library in this on-device IDE you could use together with the IDE editor. https://www.b4x.com/android/forum/threads/basicide-suite-4-now-even-further-improved.134964/#content

Check the length of b(). You only seem to be specifying two bytes but ByteConverter needs four bytes to create an Int as it divides the length of the byte array by 4 to know the length of the Int array to create for the conversion so you are getting a zero length i() array. As an aside I wrote...

As @Daestrum says above, there is no need to explicitly destroy class instances in Java. As long as you have no references to it stored anywhere then the Java Garbage Collector will take care of reclaiming its memory - that's what it is designed to do!

You are writing to a network port from the main thread and recent versions of Android don't like that. You should be using AsyncStreams in the RandomAccessFile library.

Oooh! - you big tease you! :icon_clap:

"FF FE" is a little-endian UTF-16 BOM! "22 00" is the UTF-16 quote character which might be expected to be the first character in a csv file.

Perhaps the UTF-8 encoded data starts with a Byte Order Mark which case Asc(data.CharAt(0)) will be code 65279. I don't see why you would see two diamonds though. :confused:

There's a null pointer exception being thrown in a Timer object. It's probably be due to this Timer bug. Setting the interval starts the Timer ticking and if this is done before the Timer is Initialized then a null pointer error occurs when the Timer tick occurs. EDIT:- Strictly the exception...

I suspect that the content pointed to by the DEFAULT_NOTIFICATION_URI field does not exist on the emulator.

Ahem! actually ... Sub Btn1_Click Dim Obj1 As Reflector Obj1.Target = Obj1.CreateObject("android.provider.Settings$System") Obj1.Target = Obj1.GetField("DEFAULT_NOTIFICATION_URI") Dim args(2) As Object args(0) = Obj1.GetContext args(1) = Obj1.Target Dim types(2) As...

Why can't you just do myvar.width if myvar contains a reference to the Panel you want? You can make myvar a Panel or a View variable and assign any Panel object to it.

I'm afraid that it is an Android "feature" when using keyboard entry into a dialog. There is nothing that can be done about it.

Depending upon what you want your commands to do you might be able to use my BasicLib interpreter or, for expression evaluation only, it's ExpressionEvaluator subset.

Every library comes with an XML document that (more or less depending upon the author) documents it. The XML may beviewed with my off-line viewer or the same information can be seen online here.

Android does not actually support modality. Basic4 android implements it's own form of modality for Msgbox. Look at my Dialogs library for a set of modal dialogs that use the Msgbox modality mechanism, including a couple of custom dialogs that accept a Panel that can contain other views. If you...

There are at least two ways to achieve this. Both should be easy to implement using the existing main activity of BasicIDE as a starting point. One way would be to make a new project, include the .src as a resource (Files tab) and change the main activity of BasicIDE to load this from...
