LibUSB for Xojo in next MBS Plugins

Quite a few Xojo developers use our MBS Xojo USB Plugin to connect to devices, do measurements, exchange data and query information for their applications. Wether this is a scale to weight items, barcode devices, various sensors or just a special label printer, we do provide classes to help you.

For some time now we got HIDAPI classes to replace the older MacHID, LinuxHID and WinHID classes to provide a cross platform interface for USB devices with HID protocol.
And now we replace MacUSBConnect and WinUSB classes with our new LibUSB classes.

The new plugin classes are based on the open source LibUSB library, which works on MacOS, Windows and Linux. With quite a few Linux distributions, it comes preinstalled. The library itself is licensed LGPL, so you can load it in commercial applications, but distribute it as DLL/so/dylib file.

The new LibUSBDeviceMBS class provides functions to list devices and query information. You can open a connection to a device and transfer data as needed. The example project lists all the devices and even works nice on Raspberry Pi.

Will be included in next prerelease or if you like to try now, please do not hesitate to contact us.

Xojo Meetings for Montreal and Toronto

As I travel to Montreal for the Québec FileMaker conference, I'd love to have some Xojo meetings with local developers:

If you live in this part of Canada, or you like to come over from the USA, please join those surveys to find the perfect date between 12th to 19th March 2018:

Survey for Toronto   Survey for Montreal

I know I have 15 Xojo developers using my plugins in Montreal alone and about 30 in Toronto. If you like to join, please contact me soon.

I reserve a table in a nice restaurant and I will be there. You can join and we can shop talk all night. Ask me plugin questions, bring your laptop and show projects.
And of course we discuss latest changes in Xojo, upcoming conferences and what's new in plugins.

Of course it is possible to arrange private meetings for consulting while I am in the city.

SMTP Server Settings

Sending Emails with various servers can be a challenge. In this blog article we like to collect the settings needed for using our SendMail functions in FileMaker or CURLEmailMBS class in Xojo to send emails. As you see we always prefer to use encryption.

Bei checking certificates, we can detect and avoid giving our password to a transparent proxy. And we enable TLSv1.2 for all here and require encrypted connection. It's important to test and verify this, as I once run into a hotel reading my emails to count them and prevent spamming. (more)

Windows Scripting

We do support running Windows scripts with both JavaScript and VBScript with our plugins for Xojo and FileMaker:

In Xojo, you can use the WindowsScriptMBS class. It allows you to add code, evaluate some expressions and run functions with parameters. Errors are reported and you can even define a timeout.

In FileMaker the WindowsScript functions to do the same. Our examples show how to use various scripts to use OS functions in FileMaker.

Microsoft did not port the ScriptControl to 64-bit, so by default the plugin functions only work properly in 32-bit. But the open source Tablacus Script Control 64 does work in 64-bit with our plugins. The source code is available here:

Of course nowadays you can do a lot of things directly instead of using VBScript. But if you have existing scripts, it may be convenient to use the plugin functions to run it.

Adding custom icons for MacOS in Xojo

IconsRecently a client asked how to modernize the old icon setting code to work in 64-bit targets. We used to do this via Folderitem.AddCustomIconMBS function and IconFamilyMBS class. But those are primary using old Carbon code with GWorld and IconServices library. Now Apple deprecated that in favor of NSWorkspace's setIcon method.

So today we want to show you how to add a custom icon to a file with three sample snippets. First with an existing picture, second with creating a picture with alpha channel and third one with a masked image. Depending on what you do, all ways work, but if you have an image already or just compose one for the new file, one way may be better suitable.

First, with an existing picture in the project or a variable:

// write a file dim f as FolderItem = SpecialFolder.Desktop.Child("test.txt") dim t as TextOutputStream = TextOutputStream.Create(f) t.WriteLine "Hello" t.Close // use existing picture dim g as new NSImageMBS(SomePicture) dim b as Boolean = NSWorkspaceMBS.setIcon(g, f, 0) if not b then MsgBox "Failed to add icon" end if
Second, with alpha picture:
// write a file dim f as FolderItem = SpecialFolder.Desktop.Child("test.txt") dim t as TextOutputStream = TextOutputStream.Create(f) t.WriteLine "Hello" t.Close // create picture for icon with alpha dim p as new Picture(512, 512) dim pg as Graphics = p.Graphics pg.ForeColor = rgb(255,0,0) pg.FillOval 0,0,p.Width,p.Height // add icon dim g as new NSImageMBS(p) dim b as Boolean = NSWorkspaceMBS.setIcon(g, f, 0) if not b then MsgBox "Failed to add icon" end if
Third, with masked picture:

// write a file dim f as FolderItem = SpecialFolder.Desktop.Child("test.txt") dim t as TextOutputStream = TextOutputStream.Create(f) t.WriteLine "Hello" t.Close // create picture for icon dim p as new Picture(512, 512, 32) p.Graphics.ForeColor = rgb(0,0,0) p.Graphics.FillRect 0,0,p.Width,p.Height p.Graphics.ForeColor = rgb(255,0,0) p.Graphics.FillOval 0,0,p.Width,p.Height // add mask dim m as Picture = p.mask m.Graphics.ForeColor = &cFFFFFF // first all white m.Graphics.FillRect 0, 0, p.Width, p.Height m.Graphics.ForeColor = &c000000 // visible parts black m.Graphics.FillOval 0, 0, p.Width, p.Height // add icon dim g as new NSImageMBS(p) dim b as Boolean = NSWorkspaceMBS.setIcon(g, f, 0) if not b then MsgBox "Failed to add icon" end if
We hope those snippets help you and if you have questions, please do not hesitate to contact us.

PS: The Xojo project icon made with our QuickLook extension.

The Status of our PHP support

As you may know we provide PHP support in our Xojo and FileMaker plugins. You can load a precompiled PHP library, get/set variables and run PHP code. That is useful for reusing existing PHP code in your solutions. There is a wide variety of uses including processing JSON or XML, doing SOAP or REST requests for various web services, calculating hashes or tokens for authentication or using the same functions in Xojo/FileMaker for encryption as in the PHP code running on your website for the counterpart.

We added PHP support a long time ago. At least 9 years ago for Xojo (called REALbasic at that time) and later for FileMaker in the year 2012 with version 2.9, about 5 years ago. The code is mostly identical for both and even allows to call back to the host application. In Xojo you can call an event in your Xojo code. In FileMaker you can trigger scripts, use evaluate and SQL to query your database. It works quite well for a few customers. (more)
