BluetoothLE Watcher on Windows

For next version 22.5 of MBS Xojo WinFrameworks Plugin, we upgrade our WindowsBluetoothLEAdvertisementWatcherMBS class and improve the example:



With our new BluetoothLE Device example file, we use the watcher to look for a heart rate device, query the services and when we find the heart rate service try to read the values.

News from the MBS Xojo Plugins Version 22.4

In this article I want to introduce you the new functionalities from the MBS Xojo Plugins in version 22.4.

XML

In our new release we have an innovation for the users of XML. You get with the new release the possibility not only to use the on-board functionalities to XML of XOJO, but can use from now on also the functionalities from the new MBS Xojo XML Plugin. We provide you for the moment 30 different classes to help you work with XML. For example, you can validate XML texts. You will be able to compare XML texts and even single nodes. With a good performance you can write, read and change data. Of course, this plugin offers a lot more than that, so feel free to try it out.

MongoDB

In the last release we introduced you to the new functionalities of MongoDB. In this release we have expanded them a bit more. The Rename method from the class MongoCollectionMBS is one that some of you may have been waiting for, because you can rename an existing collection and database. With the InsertMany methods from the MongoCollectionMBS class we can add multiple documents to a collection at the same time. To do this, we specify a JSON array or an Array with JSON objects, with the information, in the parameters. Result sets in a search over a MongoDB database can be stepped through with a cursor. We also have some new methods for the cursor. The methode ErrorDocument from the MongoCursorMBS class checks if an error occurred while integrating the cursor. If an error occurred server-side, the ReplyJSON is set to the server’s reply document with information about the error. The FindIndexes methode from the MongoCollectionMBS class fetches a cursor containing documents, each corresponding to an index on this collection. Some MongoDB commands return a cursor document. With the method NewCursorFromCommandReply from the MongoClientMBS class you create a cursor object from the response of such a command.

Android progress @ Xojo

At the Xojo developer retreat, Travis presented about Android. After years of working, they are now feature complete for version 1. That means they draw a line between things to be included in a v1.0 and things to move to a later version. And those items to go into first version are now implemented. That includes a lot of framework classes, a lot of controls, a debugger and the window editors in the IDE. 50 examples are ready and that may include even one to show how to do in-app purchase using some declares.

Currently they are fixing bugs to polish for a release, but that won't be for the upcoming version 2022r3. Even as it is in pre-release testing, some people already built applications and put them into the Play Store. If you like to try the version, please join tester group for Android and try it.

The initial release doesn't include plugin support. That also means internal plugins from Xojo will be missing on Android: XML, SSL Sockets, Shell, XojoScript, RegE and Crypto. While Xojo Inc. could reimplement those classes in Kotlin, I would enjoy if they build the code to bridge plugin code. That is a big project as they would need a framework library in C to provide the SDK functions. And then generate the wrapper code for plugin classes to call from Kotlin code to the C function and convert parameters and return values.

If such a bridge is no feasible, there may be the opportunity for someone else to start an Android code collection, like a declare library. I can't rewrite our plugins in Kotlin or pure Xojo code.

Distinct in MongoDB to find all tags from documents

Let's say you added some records into a collection for MongoDB. For example animals and they got tagged with various tags. Now you need the list of all tags to fill a popup menu. You like to avoid looping over all records to collect it yourself. The database server should do that without transferring the whole table to the client!

First let us create a few test records with our MongoCollectionMBS class:

Sub InsertDog() Dim NewRecord As New JSONItem Dim Tag As New JSONItem tag.Value("Name") = "Pet" Dim Tags As New JSONItem tags.Append tag NewRecord.Value("name") = "Dog" NewRecord.Value("tags") = tags Dim Result As String = Collection.InsertOne(NewRecord.toString) details.Text = result End Sub

MBS Xojo Plugins in version 22.4

Nickenich, Germany - (September 6th, 2022) -- MonkeyBread Software today is pleased to announce MBS Xojo Plugins 22.4 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:

We started a new MBS Xojo XML Plugin to provide you an alternative to the built-in XML classes in Xojo. The plugin is based on the xerces-c library and over time we will add more features. For now we have already 30 classes to cover the basic XML handling. The plugin supports unicode, handles memory management for you and uses exceptions to report errors. Performance is quite good and we have some special functions like ElementsByTagName() to speed up common operations.

The XMLParserMBS class can customize the parsing process with configuration options. You can filter the nodes while you parse and configure which nodes to ignore. When serializing the XML, you can apply filter and various options to generate the XML as you need.

With XMLTreeWalkerMBS and XMLNodeIteratorMBS we have two powerful classes to walk over a XML tree and visit nodes. We support for-each loops in Xojo with our various iterate classes. You can loop over the child elements in an element and over the attributes and child nodes in a node.

For our MongoDB plugin we got a few new features: We can now run InsertMany method to insert an array of documents or a JSON Array with documents and be quicker than running InsertOne for ewach of them. We added some new methods for cursor to query the error document and to build a cursor from a reply. We added Rename function for MongoCollectionMBS and provide a FindIndexes function to lookup what indexes exist.

We support iOS better with implementing DirectorySizeMBS and DNSServiceMetaQueryMBS classes and CopyPicture method in NSImageMBS for iOS.

Our ScintillaControlMBS got a border for Windows and a new Prepare event to set a few properties before the control is created.

For Windows we improved our ARM support. In SerialPortMBS class the WinRTSControl property allows you to control RTS line state directly.

The CURLSMBS class got new properties to control mime option flags, a new setting for the maximum life time connection and a property for the SHA256 hash of a SSH Host public key. We enabled zstd support for CURL in case a server uses that for compression.

For MacOS we added new events to NSPopoverMBS class to handle detached popovers better. In NSFontMBS class we added monospace system font query functions.

Finally we updated our Chromium based classes to a newer Chromium version, CURL to version 7.85.0, DynaPDF to 4.0.70.197 and SQLite to version 3.39.2.

See release notes for a complete list of changes.

MBS Xojo Plugins, version 22.4pr5

New in this prerelease of the 22.4 plugins:
  • Added monospacedDigitSystemFontOfSize and monospacedSystemFontOfSize functions to NSFontMBS class.
  • Added withOverlays parameter to ShowAllAnnotations method in MKMapViewMBS class.
  • Updated CURL to version 7.85.0.
  • Removed kError_CONV_FAILED constant in CURLSMBS class.

15 years of MBS Xojo DynaPDF Plugin

About 15 years ago we started the development of our DynaPDF Plugin.

After a year of development, the plugin was released to the public on 1st Sep 2007 with MBS Plugin 7.6pr1.

This plugin has been a big success for us and provides the PDF engine to thousands of Xojo applications around the world. Based on user feedback we got a lot of functions over the years like the raster engine, PDF/A conversion and ZUGFeRD support.

Please make sure you try the plugin, make it part of your toolbox and start to enjoy all the PDF features you can add to your application.

In this example we do a for each loop over attributes:

Sub IterateAttributeNodes() Dim doc As New XMLDocumentMBS("<doc id=""123"" value=""test""></doc>") Dim root As XMLElementMBS = doc.DocumentElement For Each e As XMLAttributeMBS In root.IterateAttributeNodes MessageBox e.Name+": "+e.Value Next End Sub

XDC Developer Retreat 2022

Just one month till the XDC Developer Retreat 2022 starts in Nashville:



Xojo Developer Retreat 2022, 19th and 20th September 2022.

Please reserve the days from 18th to 21st September in your calendar. You may want to use the weekend to come to Nashville earlier to enjoy the city and then join the get-together on Sunday evening. Two days of conference follows with a special developer adventure on the second day. Yes, instead of lots of sessions in a ballroom, Dana organized something different this time. I bet you'll enjoy it! Be sure sure to stay the night on Tuesday, so you can enjoy the dinner and travel home a day later.

You can either stay in the conference hotel ($269 USD/night) or maybe better get a cheaper hotel outside and drive daily to downtown for the conference. Or maybe you like to share a room when traveling with your colleague?
Since the conference hotel allows you to cancel, it may be good to reserve a room and later rebook it or cancel, when you find a lower rate. See you there!

Pragmas in Xojo

The Xojo compiler knows a few pragmas, so let's today dive into them:

BackgroundTasks

This flag is valid only within a method and defines whether the Xojo compiler will insert RuntimeBackgroundTask() calls at loop boundaries. This call checks if some time passed, about 60 yields per second at maximum. Then it does a thread switch and passes CPU time to the next waiting thread.

Older name was DisableBackgroundTasks, but that has the meaning of the parameter reversed.

BoundsChecking

This pragma seems to have no effect currently. The array function always raise exceptions.
I think in older compilers before LLVM, the array access was inlined and thus the compiler could leave away the check.
See Issue 39349.

Older name was DisableBoundsChecking, but that has the meaning of the parameter reversed. (more)

Quick encrypt or decrypt with DynaPDF

DynaPDF has a feature to quickly encrypt or decrypt a PDF with the simplified EncryptPDF and DecryptPDF functions. You need an instance of DynaPDFMBS class and then you can call those methods with the right file reference. Pass in the parameters needed like the user password (for viewing) and the owner password (to remove restriction and encryption). We provide several encryption variants, so you can pick the oldest acceptable one. In our example we use 256 bit AES. Here is an example snippet with two example methods:

Sub DecryptPDF(file as Folderitem) Dim pdf As New DynapdfMBS pdf.SetLicenseKey "Lite" // For this example you can use a Lite, Pro or Enterprise License Call pdf.DecryptPDF(File, pdf.kptOwner, "ownerpass") MsgBox "Decrypted." Catch d As DynaPDFErrorExceptionMBS MsgBox "Failed to decrypt PDF: "+d.message End Sub
Sub EncryptPDF(file as Folderitem) Dim pdf As New DynapdfMBS pdf.SetLicenseKey "Lite" // For this example you can use a Lite, Pro or Enterprise License Dim flags As Integer = pdf.krsPrint // forbit printing flags = flags Or pdf.krsCopyObj // deny copying content // userpass to just open and read // ownerpass to decrypt and remove restrictions Call pdf.EncryptPDF(File, "userpass", "ownerpass", pdf.kklAES256, flags) MsgBox "Encrypted." Catch d As DynaPDFErrorExceptionMBS MsgBox "Failed to encrypt PDF: "+d.message End Sub

Please try it, play with the various options on the restrictions. If you make a new PDF with DynaPDF, you can of course also apply the same encryption options for saving the new file. Let us know if you have questions.


Xojo August Sale

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

If you waited to get a Xojo license or to renew your license or to upgrade to Xojo Pro, this is your chance.

As usual, if your Xojo license is up for renewal in August or September, you can update now and enjoy a discount. If your Xojo license expired already, just get a new one. With discount this is cheaper than a regular update.

Conference tickets and add-ons are on sale, too. If you like to get one of the MBS articles there, you can use the sale price at Xojo Store or we match the price if you buy directly from us. Please contact us if you need a MBS Plugin license.

New XML Plugin for Xojo

For 20 years we used the built-in XML classes in Xojo. While they do the job basically, we had a desire for years to get something better. We now started to make an alternative implementation of XML classes based on the xerces-c project.

Flexibility

By implementing our own classes, we are very flexible on what we support. A lot of utility code we had in various projects to work on xml trees, can now be built-in to the plugin classes and run much faster. Be can also offer more customization on various options.

Unicode support

The new plugin should handle all the unicode details and work well with various text encodings. Usually we use UTF-8 or UTF-16, but we want it to work well with other encodings.

Exceptions

We use exceptions for reporting errors. The exceptions should include all details needed in the message text. As usual our plugin includes for example the index value and the ubound/count value in an OutOfBoundsException.
We like to avoid a couple of common pitfalls, so you can for example freely move nodes between documents. But please avoid recursion in your xml trees. (more)
