Happy Easter 2018

Spending a few days in Bavaria (guess which city), before the trips to Hamburg, Stockholm and Denver...

Wir wünschen frohe Ostern

Query all threads in Xojo app

As you may know Xojo has internally a list of all objects, but does not provide an official way to quickly (!) query all thread objects. Of course we could manage ourselves a list of thread objects, but that is inconvenient for projects with a lot of thread subclasses. A few years ago I made a feature request for a threads list: Feedback Case 26912.

As we just needed this today, we got the following function to find all thread objects in memory. We need this in an app to cancel all transfers when the app is quitting:

Function Threads() As Thread() #pragma DisableBackgroundTasks true dim threads() as Thread Dim o as Runtime.ObjectIterator = Runtime.IterateObjects While o.MoveNext dim v as Variant = o.Current if v isa Thread then threads.append v end if Wend return threads End Function

Sadly runtime's IterateObjects method is quite slow as it does some introspection stuff which takes a lot of time (see Feedback case 47148. Probably to filter some objects from the list, which we should not see here. But maybe the method above is still useful for you?

Xojo Stammtisch in Berlin

On my next visit to Berlin, I'd love to make another Xojo developer meeting:

Einfach gemütlich zusammen sitzen in einem Restaurant oder Biergarten und über Xojo schnacken.
Gerne zeige ich auch neue Pluginfunktionen oder helfe bei Problemen mit Xojo Projekten. Einfach Computer mitbringen und was zeigen.

Bei Interesse bitte eintragen in die Umfrage hier: Berlin Stammtisch

Arbed 1.8.7 updated for Xojo 2018r1

Thomas Tempelmann recently announced a new version of Arbed. As Xojo evolves over time and changes the file format, Arbed as to be updated to recognize any changes in the format. The new version knows about the most recent changes in the upcoming Xojo 2018r1.

Every Xojo developer should have it in his tool chain and enjoy the features. It has many features and depending on your needs, you may decide which feature is worth the price. For myself i mostly use it to automatically convert my example projects to HTML files to include them in the documentation. In other cases Arbed helped to recover corrupted project files and to compare two versions of a project which have been modified independently without version tracking software. It is also useful to bundle a project with all required files if you need to send a project to a client.

Arbed is highly automatable and can be scripted. You can call it from command line in your shell scripts to do various actions in batch operations. If you need, you can use it to obfuscate strings (e.g. SQL queries) in your application or prepare it for localization. Anything automated which saves a few hours is worth the money.

Arbed is available on tempel.org for $29 or $89 USD.

CURL birthday and conference

Today CURL library and command line tool turns 20 years old. It's a long time in software business and a great success with curl on nearly every computer device on earth as it ships for example with MacOS, Google Chrome, Linux, Android and others.

Since January 2007 and the MBS Xojo Plugin 7.0, we do include CURL for up- and download via ftp/http.

Since January 2012 and the MBS FileMaker Plugin 2.5, we include CURL functions for FileMaker.

And as far as I see, FileMaker Inc. added CURL right to the database engine with version 11 of FileMaker, but only added CURL options for Insert From URL script step with version 16.

See blog post from Daniel Stenberg.

For mid April we have the CURL conference on the agenda in Stockholm. Please join it if you like to learn more about CURL. See announcement and wiki page.

Interested in a meeting for FileMaker or Xojo?

Under the Radar Podcast

Over the last year I enjoyed listening to all of the episodes of the Under the Radar podcast.

Originally pointed to by Paul Lefebvre's tweet, I quickly subscribed as they talk about various topics for independent app developers and those episodes are very interesting. They face similar issues as myself and so I like to hear their solutions.

Thanks to David Smith and Marco Arment for their apps and the podcast.

And thanks to Xojo Inc. for supporting the shows. Xojo is sponsor for the current episode #123: WWDC 2018 Preview, Watch Stats. And you can get a 20% off for Xojo licenses with coupon code RADAR2018.

Do you like this podcast?

PS: Coupon code updated.

MBS Plugin classes for use on Raspberry Pi

Did you know we compile all our plugins to run on Raspberry Pi, too?

Of course classes for Mac and Windows will do nothing on Linux, but you can still have them in the code and they will not cause compile errors. This allows cross compilations from Mac to Linux or other way around.

The following MBS Plugins can be used on a Raspberry Pi:
And in the documentation, you can click on a list of classes and than click on the Linux platform, which hides all the classes that won't work on Linux.
The Linux plugin includes the RaspberryPiCameraMBS class to get pictures on a Raspberry Pi camera, the avahi classes for finding devices on the local network, the GTK window classes, the WebKit HTMLViewer extensions and help for sudo. Enjoy!

MonkeyBread Software Releases the MBS Xojo Plugins in version 18.1

Nickenich, Germany (March 6th, 2018) -- Monkeybread Software releases version 18.1 of the MBS plug-in for Xojo.

The MBS plug-in comprises a collection of several plug-in parts which extend the Xojo (Real Studio) development environment with 2,300 classes featuring over 60,000 documented functions. Our plugins support all three platforms Mac OS X, Windows and Linux with all project types desktop, web and console including 64-bit and ARM targets. Some of the highlights on the 18.1 update:

libusb is a library for C developers, which provides generic access to USB devices. You can use it within your normal applications on various operation systems including Linux, MacOS and Windows. All USB versions from 1.0 to 3.1 are supported. The MBS Xojo USB Plugin now contains the classes to use LibUSB in Xojo. It joins existing classes for HIDAPI to talk to USB HID devices, our classes for smartcard readers and various dongles.

For better compatibility to future MacOS versions, we reduced dependencies to the Carbon frameworks for our 64-bit plugins. 16 of 472 plugin parts still need Carbon framework in 64-bit, e.g. for Apple Events, Carbon Events and Timers.

If you use our PHPMBS class, you can now enjoy getting detailed error messages when execution fails. The callback from PHP to Xojo can now be reached via CallXojo method, which triggers the Callback event.

Our Java loading code has been updated for version 9 of the Java Runtime Environment. You can now use all Java versions from 1.4 to version 9.

The SQL Plugin got improvements with fixes in the exception handling for the Linux ARM target. For prepared statements, we added support for binding dates with the Xojo.Core.Date class. Our plugin now works with both SQL Anywhere API in version 1 and 2. The new Options dictionary for SQLDatabaseMBS, SQLConnectionMBS and SQLCommandMBS allow you to inspect all set options defined for connection or command. Finally connections can now be reused properly.

For MacOS, we got the StoreKit classes updated for new classes in MacOS 10.13.2 and support for offering trials. Several improvements with threading should fix issues you may have seen with Store transactions.

The Cocoa textview and Xojo textarea controls can now use the NSTextListMBS class on MacOS to handle lists within texts. Lists can be ordered or unordered and use various styles. NSParagraphStyleMBS and related classes have been updated to help define proper list styles.

The new WindowsDisplayMBS class allows you to check the available displays on Windows in detail. Beside listing which adapter has which display from which manufacturer, you can now also detect physical size of the display as well as the physical resolution.

Enjoy improved email sending, better channel handling for PictureMBS class, 64-bit upgrade for EncryptMBS class, better MeasureRotatedTextMBS function on Windows and improved CURLSMBS.SetupAWS function for Amazon S3 and Dell ECS.

Finally we updated the CURL library to version 7.58.1, DynaPDF to version, LibXL to version 3.8.2, SQLite to version 3.22.0, the JPEG library to version 9c and LibTiff to version 4.0.9 including support for BigTiff format.

See release notes for a complete list of changes.

Microsoft SQL Server connectivity

Sometimes you need to connect to Microsoft SQL Server and you know it's not as easy as with MySQL or PostgreSQL. SQL Server is a bit different which makes trouble and things more difficult.


On Windows we can just connect with "WIN-TEST\SQLEXPRESS@test" here and use Windows authentication. WIN-TEST is the name of the windows machine, SQLEXPRESS the name of the instance of the Microsoft SQL Server. After the @ comes with name of the database.

If we disable Windows authentication and enable login via name and password, define a new login "test" with password "hello123" and than we can just connect on Windows using the following code:

dim con as new SQLDatabaseMBS con.Option("UseAPI") = "ODBC" con.DatabaseName = "SQLServer:WIN-HO9KHI2N15T\SQLEXPRESS@test" con.UserName = "test" con.Password = "hello123" con.Scrollable = false // disabling scrolling cursors is much faster for Microsoft SQL Server... if con.Connect then Msgbox "Connected" Else Msgbox con.ErrorMessage end if
This does work on Windows PC. The same connection also works with TCP/IP as "tcp:\SQLEXPRESS,1433@test". As you see we use IP here and the port 1433 separated by a comma. For this to work, the server must explicitly be configured to allow TCP/IP connections and to listen on the IPs of the server with the given port. This works well from a second PC.


On MacOS, we can use the freetds library. On our website, we have a copy for you to download (http://www.monkeybreadsoftware.de/xojo/download/plugin/Libs/). We can use the ODBC connection type and the libtdsodbc.dylib library file. This library file allows us to make a ODBC style connection directly to the Microsoft SQL Server giving the port, IP and database name:

dim con as new SQLDatabaseMBS con.Option(con.kOptionLibraryODBC) = "/Users/cs/Desktop/libtdsodbc.dylib" con.DatabaseName = "ODBC:DRIVER={FREETDS};Server=;Database=test;TDS_VERSION=7.2;Port=1433" con.UserName = "test" con.Password = "hello123" if con.Connect then Msgbox "Connected" Else Msgbox con.ErrorMessage end if

To connect on Linux, we need to install tds for ODBC, e.g. with the command "sudo apt-get install tdsodbc".
dim con as new SQLDatabaseMBS con.DatabaseName = "ODBC:DRIVER={FreeTDS};Server=;Database=test;TDS_VERSION=7.2;Port=1433" con.UserName = "test" con.Password = "hello123"
If you have no odbcinst.ini file in /etc, you can specify the .so library directly in the connection string instead of {FreeTDS}, you would specify libtdsodbc.so directly. If everything works fine, you get your connection and all texts send/received. There is a problem that freetds can be compiled for UTF16 or UTF32 and if it doesn't match your iODBC compilation setting, it will fail to pass any text.

MBS Xojo Plugins, version 18.1pr6

New in this prerelease of the 18.1 plugins:
  • Added check for PictureMBS.DataStringInFormat to raise exception if you try to request too big memory blocks.
  • Added LogPixelsY and LogPixelsX properties for WindowsDisplayMBS class.
  • Reduced plugins linking to Carbon framework for 64-bit.
  • Changed WindowGroupMBS class to raise exception if used in Cocoa project.
