RB/Xojo: Goodbye, you old dinosaur…

42

And I mean this in an very friendly way, referring to one of their latest campaigns 🙂

I was doing some early spring cleaning on the dusty attic of this blog and came across some old projects I did.

Some of you long time followers of my blog may remember I wrote several posts programming in Xojo (previously RealStudio or even RealBasic before that).  When I first started this blog, I was a huge fan of RB.  The familiar VB6 syntax was what me attracted to it in the first place. I had a VB6 background, and with Microsoft abandoning it, RB was a nice alternative.  I really didn’t care much for it being able to cross compile back then as Windows was my thing.  But it was nice that it could.

Back then, many years ago, I used this place to write articles mainly on the Canvas (an 11 episode series!) and vintage games.

But also some frameworks like ABXVision that had OpenCV like capabilities (Augmented Reality in its early stages!) and a full blown physics engine ABPE.

The robotics series was a very fun project to do.  I was doing a course on Artificial Intelligence at the time and I could use this new knowledge in the tutorials.

But because of Xojos decision a couple of years ago to start using a new syntax framework, most of these projects won’t work anymore without a major overhaul.  So I feel it is time to let them go. I recently noticed Xojo had removed this blog from their resource list too, so they must’ve had the same feeling. Honestly, no hard feelings about that! I would too when a blog doesn’t write anything on me anymore.

But what is there currently to write about Xojo? The Web part hasn’t changed in many years and still looks like it is 1995. iOS still feels like it is only partly finished and is missing to many out-of-the-box features to be useful (will the new upcoming android suffer from the same problem?).  Should I write about the many bugs and workarounds one has to do?

It must be said many of this remarks have to do with Xojo being a small team, and some stuff (like 64bit or Apples decisions) has been forced upon them.  Luckily they have a small but enthusiastic community which is willing to take over the many shortcomings by writing frameworks like Aloe or iOSKit.

So, time to put those fond memories into a box and leave memory lane.  Back to the real harsh world ;-).

I will leave the RB/Xojo projects on this blog until the end of the month (March).  Maybe, one day, I will find the time to revamp them in Xojo or put them all up on GitHub and they will reappear.

Until then, this blog will mainly report on B4X and my own framework ABMaterial.

Godspeed old friend(s). Until we meet again…

UPDATE: I was planning to make a separate blog section for my old RB/Xojo projects, but I just can’t find the time to do so. I created a raw FTP dump of everything RB/Xojo related today that you can download from here. It is a bit messy so you will have to browse through it yourself. A lot of it will probably be outdated (the main reason I removed everything from my blog) and will need some re-work, but some of it may still be useful for someone.

B4X: Important upgrade to ABMaterial 4.03 for everyone!

ABMDragonfly4.00

As you probably already have noticed, the B4J IDE Project Explorer has received a major upgrade. And it is GREAT! However, ABMaterial had some trouble with the new file format, so last night I’ve been working non-stop on a fix to be compatible.

If you are using B4J 6.00+, you MUST download 4.03 or higher.  For that reason, EVERYONE (donator or not), can upgrade to the new version.

You can download the latest version of ABMaterial Dragonfly here.

Until next time!

B4XHelp: An ABMaterial WebApp for B4X Library documentation

b4xhelpI’ve created an ABMaterial (3.75) WebApp to show the documentation for the B4X libraries. Everyone who created a library for B4A, B4i or B4J can upload their .xml file to the WebApp and everyone can consult it. You can re-upload a new version for a library if needed.

NOTE: not online anymore! In the zip is the source code of the webapp so you can run it yourself.

b4xhelp

Notes:

  • This WebApp is open for everyone, but please try to keep it clean. Thank you!
  • B4XHelp is running on my personal Raspberry Pi with not a super-duper internet connection, so it also may give some indication how it handles a lot of users.
  • The libraries itself are NOT uploaded to the WebApp! Only the .xml files to parse them.
  • The WebApp also runs on a HTTP/2 server, but I do not have a verified certificate. If you use this link, you will get a warning that it may not be safe. You normally only need to accept this once:

priv

ABMaterial may be overwhelming at first with all its features at your disposal, but once you get the hang of it, creating such a WebApp as this, in pure B4J, can go very fast.

B4J: Printing/Reporting with upcoming ABMaterial 3.75

2
A sneak peek on a new feature of ABMaterial for B4J I’m working on: Printing/Reporting.

This is an example of a report in ABMaterial. You build it right into your other pages and just by setting a couple of parameters, you control what will be shown on screen and what will be printed.

1
The block your see above ‘INVOICE’ will not be printed, just my setting lbl.IsPrintable = false.  What is shown on screen you control by using the normal ABM.VISIBLE_ constants. For example there are some additional notes with a chart that you can’t see here on screen, but will be printed.

You can use almost every ABM component in your report. Good examples are the ABMChart, the ABMChronologyList or even like in this example you can let your client sign the document using an ABMSignaturePad and print it right out.

The ABM components avoid being split over two pages (e.g. an image will be printed on the next page if it does not fit). Browsers let you control very little on how things are printed, but I’ve added some things like ReportFooter.row(3).PrintPageBreak = ABM.PRINT_PAGEBREAK_BEFORE_ALWAYS to give you some control.

Note that the navigation bar is not printed either. All of this is taken care for you automatically by ABMaterial!

3
Some example pdf prints from the demo app (without making any modification to the source code!). Try printing the same pages with ABMaterial 3.50 or before and you’ll see the difference.

http://gorgeousapps.com/PrintExamples.zip

Making the above ‘invoice report’ is really simple and in the spirit of ABMaterial. I’ve created a new component ABMReport (and ABMReportBlock) which you can use just like you would make an ABMCustomComponent.

Relevant source code snippet of the above report (the Build event is where the magic happens, the rest are more helper methods):

Sub Class_Globals
   Dim ABM As ABMaterial
   Dim Report As ABMReport

   ' some CSS to format the 'body' of the report
   Dim ReportCSS As String = $"
   .repheader, .repfooter, .repheaderright, .repfooterright {

     font-size: 1.8rem;
   }
   .repheaderright, .repbodyright, .repfooterright {
     text-align: right;
   }
   .repbody, .repbodyright {
     font-size: 1.5rem;
   }

   @media only print {
     html { font-size: 60%}
   }"$

...

It will never be able to print everything of course (e.g. scrolling components), but I’m pretty happy with the things it will be able to do.  Browser support for report printing is still in its infancy I’m afraid and it will take some time before all browsers are lined up supporting all HTML printing features.

But, together with the new ABMreport component, you will already be able to create reports with very little effort using ABMaterial and B4J!

ABMaterial 3.75 will be available for donators in a couple of weeks.

B4J: IMPORTANT change in ABMaterial for B4J 5.80+

As B4J 5.80 has been updated to Jetty 9.4.6 (which contains an important change in the internal Session framework), you will need to update some code in StartServer() and StartServerHTTP2() in the ABMApplication module.

In pre B4J 5.80 with Jetty 9.3.x it was:

Dim joServer As JavaObject = srvr
joServer.GetFieldJO("server").RunMethod("stop", Null)
joServer.GetFieldJO("context").RunMethodJO("getSessionHandler", Null).RunMethodJO("getSessionManager", Null).RunMethodJO("getSessionCookieConfig", Null).RunMethod("setMaxAge", Array(31536000)) ' 1 year

'NEW FEATURE! Each App has its own Session Cookie
joServer.GetFieldJO("context").RunMethodJO("getSessionHandler", Null).RunMethodJO("getSessionManager", Null).RunMethodJO("getSessionCookieConfig", Null).RunMethod("setName", Array(ABMShared.AppName.ToUpperCase))
joServer.GetFieldJO("server").RunMethod("start", Null)

must be changed to this in B4J 5.80+ with Jetty 9.4.6:

Dim joServer As JavaObject = srvr
joServer.GetFieldJO("server").RunMethod("stop", Null)
joServer.GetFieldJO("context").RunMethodJO("getSessionHandler", Null).RunMethodJO("getSessionCookieConfig", Null).RunMethod("setMaxAge", Array(31536000)) ' 1 year

' NEW FEATURE! Each App has its own Session Cookie
joServer.GetFieldJO("context").RunMethodJO("getSessionHandler", Null).RunMethodJO("getSessionCookieConfig", Null).RunMethod("setName", Array(ABMShared.AppName.ToUpperCase))
joServer.GetFieldJO("server").RunMethod("start", Null)

' + This setting is with reservation until confirmation
Dim secs As Long = ABMShared.CacheScavengePeriodSeconds ' must be defined as a long, else you get a 'java.lang.RuntimeException: Method: setIntervalSec not matched.' error
joServer.GetFieldJO("context").RunMethodJO("getSessionHandler", Null).RunMethodJO("getSessionIdManager", Null).RunMethodJO("getSessionHouseKeeper", Null).RunMethod("setIntervalSec", Array As Object(secs))

This will be corrected in the next upcoming release 3.75 of ABMaterial.

B4A + B4J: Profile your apps ‘live’ with ABMonitor

ABMonitor2

It has been some time since I could give my donators a new goodie;), and this time it is a library/tool to profile and monitor your B4J + B4A (7.01+) apps (not limited to ABMaterial WebApps!) I’ve been needing something like this for some time for my own projects, but couldn’t find one that suited me.  This can be a very good asset to find Memory Leaks or to track which method takes up to much time.

Using a very simple API, you can track how long the code execution time is, the times hit, average time, memory usage etc for any block of code you want to investigate.  I deliberately gave you this API freedom, as profiling ALL your code (as most programming languages do) is just drowning you in to much information so you don’t see the wood for the trees anymore.

QUICK NOTE: Do not forget to set your DONATORKEY and the port in the Viewer params.txt . The same port and the IP of your Viewer have to be used in the apps you are monitoring!

How it works:
ABMonitor uses the Jamon library, which has a extremely low overhead on your code. Just by disabling it (using the SetActive method), you can actually leave it in your production apps if you want (or use B4Js conditional compiling if you want to get rid of it all together in a production app).

ABMonitor consists of two main parts:
1. The ‘live’ ABMonitor Viewer.

Instructions: Simply start the Viewer in a command prompt using: java -jar ABMonitor.jar

This Viewer shows all the stuff you are monitoring with the API. It shows e.g. how many times some part of your code was hit, how long it took, what the average time was, when it was last accessed, memory consumption etc… It is presented in a TreeView Table, so you can check every detail (depending on how deep you’ve coded your profiling).  At the bottom, the last 50 runs are presented in some line charts.

Because the IDE of B4X is ‘live’, so is the Viewer! Thanks to this unique feature of the B4X products, you can update your code and see the results in the Viewer immediately.

Little side note: This ‘live’ IDE part is a little-known/promoted feature (except within the B4X community of course, as for us this is normal), but it has a HUGE advantage over any other tool out there.  In similar market aimed tools, like Xojo for example, you have to compile and re-compile every single time you make the smallest of changes to your code (on bigger projects it takes up to 20 minutes, some users reported). In B4X, just change the code, and continue running.  Not happy with it? Change it again and see what gives. BIG production time-saver! Some of you who used to program in VB6 know what I mean…

2. The ABMonitorB4X libraries (ABMonitorB4A.jar/ABMonitorB4J.jar).

Install instructions: Copy the xml and jars (dont’t forget jamon-2.81.jar), to your B4A or B4J libraries folder. In the IDE select the ABMonitorB4X library, the RandomAccessFile library and the Network library.

This API connects your own apps with the monitor. It basically consists of a Start and a Stop method.

First, we have to make the connection with the Viewer. Thanks to Erels new Resumable Subs, doing this is a breeze:

In Main make some declarations:

Sub Process_Globals
   Public Monitor As ABMonitor

   Private port As Int = 10090 ' <-- Set your Viewers Port!
   Private ip As String = "127.0.0.1" ' <-- Set your Viewers IP!
   Private abmonitor As AsyncStreams
   Private client As Socket

   ' Useful to quickly activate/deactivate the monitoring
   Public TRACKMONITOR As Boolean = True
End Sub

Next add the following resumable sub:

Sub ConnectMonitor()
   Dim c As Socket
   c.Initialize("client")
   c.Connect(ip, port, 5000)
   Wait For Client_Connected (Successful As Boolean)
   If Successful Then
     client = c
     abmonitor.InitializePrefix(client.InputStream, False, client.OutputStream, "abmonitor")
     Log("ABMonitor connected")
     Monitor.SetActive("Template", True,abmonitor, 5)
   Else
     Log("ABMonitor disconnected")
   End If
End Sub

Sub abmonitor_Error
   Monitor.SetActive("Template", False,Null, 0)
   Log("ABMonitor disconnected")
End Sub

You can set the interval the data should be send to the Viewer, in seconds, with the last parameter in ‘Monitor.SetActive(“Template”, True,abmonitor, 5)’.  In this example, it is every 5 seconds.  Note: This does not mean it is tracked every 5 seconds! The library will continue tracking everything, but it will only send all the info over to the Viewer every 5 seconds.

Finally, Initialize the monitor and call the resumable sub when your app starts (a good place is e.g. before StartMessageLoop in a Server app):

...
Monitor.Initialize("YOURDONATORKEY")

ConnectMonitor

StartMessageLoop

Ready to do some monitoring!

As I said, there are basically only two commands: Start and Stop.

There are two ways to monitor/profile your code (you can mix the use of them):

a. Monitor some code:
You want to monitor a query, or a whole sub, … In general this is a complete block of code.

Good practice is using the class/module name as the Group parameter, and the method name as the Label, but you can put whatever you want. This will later be used in the Viewer to group stuff. (Group and Label are the first and second parameters in the calls).

Example:

Private Sub WebSocket_Connected (WebSocket1 As WebSocket)
   If Main.TRACKMONITOR Then Main.Monitor.Start("ABMPageTemplate", "WebSocket_Connected", "")

   '   ... the code you want to monitor

   If Main.TRACKMONITOR Then Main.Monitor.Stop("ABMPageTemplate", "WebSocket_Connected", "")
End Sub

Or tracking a query:

..
If Main.TRACKMONITOR Then Main.Monitor.Start("ABMPageTemplate", "MySlowQuery", "")

Dim SQL_str As String
SQL_str = "SELECT cases.CaseID, cases.CaseUserID, cases.CaseType, cases.CaseSummary FROM tCases WHERE cases.CaseStatus=1;"
Dim cases As List = DBM.SQLSelect(SQL, SQL_str, Null)

If Main.TRACKMONITOR Then Main.Monitor.Stop("ABMPageTemplate", "MySlowQuery", "")
...

b. Monitor methods which are used in multiple places, and you want to know where it was called.
You have for example a page.Refresh method, which is called in multiple places. You can use the third parameter to set the ‘caller’. In general there will only be one line of code between the start() and stop().

This caller will later be used in the Viewer to build a call tree (or stack trace)

Example:

Private Sub WebSocket_Connected (WebSocket1 As WebSocket)
     ...
     If Main.TRACKMONITOR Then Main.Monitor.Start("ABMPageTemplate", "page.Refresh", "WebSocket_Connected")
     page.Refresh
     If Main.TRACKMONITOR Then Main.Monitor.Stop("ABMPageTemplate", "page.Refresh", "WebSocket_Connected")
     ...
End Sub

public Sub ConnectPage()
   ...
   ' refresh the page
   If Main.TRACKMONITOR Then Main.Monitor.Start("ABMPageTemplate", "page.Refresh", "ConnectPage")
   page.Refresh
   If Main.TRACKMONITOR Then Main.Monitor.Stop("ABMPageTemplate", "page.Refresh", "ConnectPage")
   ...
End Sub

As you can see, you are totally free to monitor anything you want.

Call for action: if anyone out there is a guru in making B4i libraries, please PM me!  The java library code is quite simple and it shouldn’t be to hard for an experienced B4i library coder to write one which can connect to the same Viewer.  If we got this one too, then we’ve covered all major platforms in B4X!

ABMonitor is part of a multi-pack on libraries, frameworks and tools all Donators to this blog receive.

Included are currently:

ABMaterial (B4J) A very powerful framework combining a tuned Materialize CSS with the free programming tool B4J. It allows creating Web Apps that not only look great thanks to Googles Material Design, but can be programmed with the powerful free tool from Anywhere Software without having to write a single line of HTML, CSS or Javascript code!

ABExchange (B4J) It can be used to sync the ABMCalendar control with your exchange server and outlook. It can also send a mail.

ABJasperReports (B4J) his is a little library that allows you to export reports created in Jasper Reports in your B4J applications. They can be exported to pdf, html and xls. You can use parameters defined in JasperReports.

ABPDFBox (B4J) With this library you can print PDF files (either by showing a dialogbox or directly to a specified printer). Works in UI and NON-UI apps.

ABMonitor (B4J + B4A) Tool to monitor/profile your B4A (7.01+) and B4J code! Includes the libraries for both platform + the ABMonitor Viewer. See the tutorial for more info.

ABCron (B4J + B4A) A more advanced timer library that can schedule more intelligently tasks using Cron expressions. You can also set a start and end datetime. I’ve added a method RestartApplicationNONUI() that should restart you .jar file when the Cron expression is met.

ABEvaluator (B4J + B4A) Evaluate mathematical expressions. You can also write your own functions in B4J/B4A.

ABPlugin (B4J) Create Live plugins for you own apps. This means you can create plugins that can be added/removed while your app is running. Note it is a little experiment that shows the power of B4J. The ‘compile to library’ feature of B4J is very handy to create plugins.

ABZXCVBN (B4J + B4A) Realistic password strength estimation.

ABTreeTableView (B4J) Custom B4J component which combines a TreeView with a TableView.

Until next time!
