Save the date for another Xojo Conference in Germany

Since Xojo Inc. doesn't plan one, we step in and invite you to come to our home country. To keep it easy for us, we'll have the conference nearby here and we would enjoy, if you join us and visit the area here.

The MBS Xojo Conference will take place Thursday, 25th and Friday, 26th April 2024 in Andernach in Germany, a town nearby here at the river Rhine. We look forward to host around 50 Xojo developers here, have various speakers for the sessions as well as several workshops and labs.

You can come by train or by car there and we encourage attendees to stay the weekend and explore the area. If you take a train, you find plenty of direct train connections from Hamburg to Munich, Berlin and Luxembourg. If you fly, look for flights to Frankfurt or Cologne and take trains from there to Andernach station. From the station, you can about walk 1 km to the hotel.

For Wednesday, 24th April 2024 we plan a Xojo training day, where we will develop various projects in Xojo. We include various things attendees like to see. For example we could write a desktop app to manage a database, then a web app to use the same database. For mobile users we could make a little web service providing the data to an iOS and/or Android application.

Attendees coming from abroad can stay a bit longer. We plan to have a sight seeing day for Tuesday to visit some nice places and show you a bit of the landscape, the history and the culture. Enjoy extra days here and plan to visit the world's highest cold-water geyser, which erupts up to 60 meters high in the nature reserve Namedyer Werth.

The planning of the conference involves all the things we learnt from previous conferences. Skipping expensive hotels in big cities to make the conference more affordable. The key thing is to bring together developers from all over the world to exchange ideas, learn new techniques and have a great time.

More details will be announced once the paper work is finished.

Xojo Sale

Xojo Inc. announced a sale for the next few days:

Using Bonjour to find iOS companion app

Let's say you have a Xojo desktop app and you like to have an iOS app, which can connect to the desktop application. We like to avoid the user entering some kind of connection information and just automatically connect. Then once connected, the iOS app can do some things and talk to the desktop app for more. Let's say the desktop app manages the database and the iOS app can show data on the go, e.g. after scanning a barcode.

For this project we use Xojo with two projects, one for desktop and one for iOS.

Desktop Project

We use a ServerSocket to wait for incoming connections. We let the ServerSocket pick a random port instead of relaying on a fixed port number.

Public Sub StartServer()
  ServerSocket = New MyServerSocket
  ServerSocket.MinimumSocketsAvailable = 3
  System.DebugLog "Waiting on port "+ServerSocket.Port.ToString
End Sub

News from the MBS Xojo Plugins Version 23.2

In this article I want to introduce you the new functionalities from the MBS Xojo Plugins in version 23.2.


With the new method SharedInstance from the classes CURLMultiMBS, CURLNMultiMBS and CURLSMultiMBS we simplify the multi transfer for our Xojo CURL Plugin. If you want more information to that then read our blogpost Easier multi transfer for our Xojo CURL Plugin. For The CURLMultiMBS classes you need a timer that calls Perform regularly. If you want to run Perform automatically you can set true in the AutoPerform property.


Since a few releases we also have the possibility to connect to a MongoDB database and work with it. Also in this release we extend the functionalities of MongoDB. First of all we can now convert information as Binary JSON for Mongo DB. The information is first read in an encoding of your choice or by default with UTF-8, converts to base64 and embeds it in a $binary JSON for use in MongoDB. You can use the method DataToBinary from the class MongoClientMBS for this. The data is passed as a string or MemoryBlock.

Two other new methods of this class deal with time in MongoDB. With the method NowUTC we get the current UTC timestamp. This can look like this:

{ "$date" : "2023-03-09T11:39:34Z" }
Matching to this there is the method Time which gives us the matching UTC timestamp in a JSON with a time as seconds since 1970 specification.


Xojo Conference Survey results

Thank you all for answering our survey about a potential conference in 2024.

We got 66 answers. From that 20 people answered that they would come, plus 27 with a maybe. We also got 10 people unlikely to show due to various concerns (time, location, money) and 9 straight nos.


One year CURL sponsor

We are happy to sponsor the CURL project for a year now. And maybe your company could also find and support an open source project?
Join in and Sponsor!
Please consider sponsoring the project. Maintaining, bug tracking, hosting and supporting this project requires resources. You can help!
We do not consider single-shot donations as "sponsorships". Those are donations and while welcome, they will not be honored by a mention here. Sponsors mentioned here keep supporting the project long-term by covering some sort of notable cost to the benefit of the project and its users.
The best way to sponsor this project is to allow a paid engineer or two to spend work hours on curl. Responding to email and writing curl improvements. Alternatively, donate to curl on the opencollective page.
We promise to use donated funds only for things and activities that we believe are beneficial for the project and its development. That includes but is not limiting us to bug-bounties, developer conferences, infrastructure, services and hardware.

MonkeyBread Software Releases the MBS Xojo Plugins in version 23.2

Nickenich, Germany - (May 9th, 2023) -- MonkeyBread Software today is pleased to announce MBS Xojo Plugins 23.2 for macOS, Linux and Windows, the latest update to their product that is easily the most powerful plugin collection currently available for Xojo. MBS Xojo Plugins have been updated and now includes over 3000 classes and 80,000 documented features, and the versatile plugins have gained more new functions:

For Windows we add classes to use the built-in PDF functionality from Microsoft. You can open PDF documents, query page count and sizes and render preview pictures of pages.

The GraphicsMagick functions got improved to now include WebP support. This includes reading and writing WebP files, so you can directly upload WebP functions from your CMS solution to your web server.

For MongoDB we have new functions to convert strings or MemoryBlocks to binary data for passing to the MongoDB database with DataToBinary function for efficient storage (without Base64 overhead). The NowUTC function in the MongoClientMBS class returns the current date in the format needed for MongoDB in JSON and Time can convert time stamps if needed.

We added new delegate based functionality to CURLSMultiMBS class to make it easier to do asynchronous transfers in the background. For this you can now use our shared instance and the AutoPerform property.

The ScintillaControlMBS control can now print and show print preview with the new FormatRange method. You can use it to render text into a picture and set various options with the new ScintillaRangeToFormatMBS class.

The CanvasGesturesMBS class is updated to work with DesktopCanvas control. The PHPickerViewControllerMBS class is updated to work on macOS and not just on iOS. We updated our Java classes for Java versions 19 and 20. The MFPMediaItemMBS class can now return details on the audio channels, frame rate, bits and samples. The archive classes can now handle lz4 and zstd compression methods. For Windows you can now control the printing for WebView2 with the new WebView2PrintSettingsMBS class.

Finally we updated curl to version 8.0.1, LibArchive to 3.6.2, libwebp to 1.3.0, SQLAPI to 5.2.4b3, SQLite to 3.41.2, libXL to 4.1.2, and Xcode to version 14.3.

See release notes for a complete list of changes.

How about having another Xojo conference in 2024?

We enjoyed past Xojo conferences and we were a bit of disappointed, that Xojo Inc. didn't announce their 2024 conference plans.

So we may go and do our best to have a conference ourselves. In past years we run 10 conferences ourselves: Several in Koblenz and London, one each in Scheveningen, Berlin, Munich and Cologne. We regularly got over 50 attendees for the last conferences. For Berlin we even had about 80 people joining, which was our best result so far.

But we don't know how much interest is there for a conference in 2024, so we start with a survey to ask past attendees and interested Xojo developers to let us know their answers to a few questions:


xDev Magazine 21.3

The May/June (21.3) issue of xDev Magazine is now available. Here's a quick preview of what's inside:

The Last XDC? by Marc Zeedar
As in-person conferences fade in popularity, we're hoping London 2023 isn't the final XDC. Meanwhile, Xojo CEO Geoff Perlman announces Android support is coming in the next release of Xojo!

Marc Goes Across the Pond by Marc Zeedar
After years of postponements and cancelations, the London Xojo Developer Conference final happens. Marc reports on his trip with tons of photos of his adventures in London and from XDC 2023.

Windows OCR by Stefanie Juchmes
The Windows operating system has built-in support for optical character recognition. Stefanie explains how to use it via the Monkeybread Plugins for Xojo.

Raspberry Pi Electronic Fun, Part 1 by Eugene Dakin
Eugene begins a new series on how to use the LibGPIOD interface for Raspberry Pi. In this installment, he explains what LibGPIOD is and why you'd want to use it in your next Pi project with Xojo.

Plus: Topics such as Xojo preferences and using Big Numbers with MBS, and more!

Thoughts about conferences

After the pandemic we come back to in-person conferences. But things are a bit different. People prefer to watch educational content on a website from home instead of sitting in a school class setup at a conference. Both Xojo and Monkeybread Software don't time development to the conference, so we don't have shiny new things to show off. If a new feature would be ready to go into a beta version, you would have seen it already.

The social get-together is a great part of the conferences. You meet people from the community, who you may not have seen in years. You talk with everyone to learn what they do and you discuss various aspects of the Xojo development with your peers. Once you know people in person, you later react different to them on the forums.
