Used on the Macintosh to convert a 4-character constant to a value that may be used by Dir, Kill, Shell, and AppActivate.

There are two kinds of add-ins: Office Add-ins from the Office Store (which use web technologies like HTML, CSS and JavaScript) and add-ins made by using Visual Basic for Applications (VBA).

The required constant argument consists of 4 characters used to specify a resource type, file type, application signature, or Apple Event; for example, TEXT, OBIN, 'XLS5' for Excel files ('XLS8' for Excel 97); Microsoft Word uses 'W6BN' ('W8BN' for Word 97), and so on.
Remarks
MacID is used with Dir and Kill to specify a Macintosh file type. Because the Macintosh does not support * and ? as wildcards, you can use a four-character constant instead to identify groups of files. For example, the following statement returns TEXT type files from the current folder:
MacID is used with Shell and AppActivate to specify an application by using the application's unique signature.

-->The TaskyVB sample application demonstrates how Visual Basic code compiled into a .NET Standard library can be used with Xamarin. Here are some screenshots of the resulting apps running on Android and iOS:
The Android and iOS projects in the example are all written in C#. The user interface for each application is built with native technologies, while the TodoItem management is provided by the Visual Basic .NET Standard library using an XML file (for demonstration purposes, not a full database).
Sample walkthrough
This guide discusses how Visual Basic has been implemented in theTaskyVBXamarin sample for iOS and Android.
Note
Review the instructions on Visual Basic and .NET Standard before continuing with this guide.
Refer to the Xamarin.Forms using Visual Basic instructions to see how to build an app with shared user-interface Visual Basic code.
VisualBasicNetStandard
Visual Basic .NET Standard libraries can only be created in Visual Studio on Windows.The example library contains the basics of our application in these Visual Basic files:
- TodoItem.vb
- TodoItemManager.vb
- TodoItemRepositoryXML.vb
- XmlStorage.vb
TodoItem.vb
This class contains the business object to be used throughout the application. It will be defined in Visual Basic and shared with the Android and iOS projects that are written in C#.
The class definition is shown here:
The sample uses XML serialization and de-serialization to load and save the TodoItem objects.
TodoItemManager.vb
The Manager class presents the ‘API’ for the portable code. It provides basic CRUD operations for the TodoItem class, but no implementation of those operations.
The constructor takes an instance of IXmlStorage as a parameter. This allows each platform to provide its own working implementation while still letting the portable code describe other functionality that can be shared.
TodoItemRepository.vb
The repository class contains the logic for managing the list of TodoItem objects. The complete code is shown below – the logic exists mainly to manage a unique ID value across the TodoItems as they are added and removed from the collection.
Note
This code is an example of a very basic data-storage mechanism.It is provided to demonstrate how a .NET Standard library can codeagainst an interface to access platform-specific functionality(in this case, loading and saving an XML file). It it not intended to bea production-quality database alternative.
Android and iOS application projects
iOS
In the iOS application the TodoItemManager and the XmlStorageImplementation are created in the AppDelegate.cs file as shown in this code snippet. The first four lines are just building the path to the file where data will be stored; the final two lines show the two classes being instantiated.

Android
In the Android application the TodoItemManager and the XmlStorageImplementation are created in the Application.cs file as shown in this code snippet. The first three lines are just building the path to the file where data will be stored; the final two lines show the two classes being instantiated.
The rest of the application code is primarily concerned with the user interface and using the TaskMgr class to load and save TodoItem classes.
Visual Studio 2019 for Mac
Warning
Visual Studio for Mac does NOT support editing the Visual Basic language – there are no menu items for creating Visual Basic projects or files. If you open a .vb there is no language syntax highlighting, autocomplete, or IntelliSense.
Microsoft Visual Basic For Mac
Visual Studio 2019 for Mac can compile Visual Studio .NET Standard projects created on Windows, so iOS apps can reference those projects.
Microsoft Visual Basic For Applications For Mac
Visual Studio 2017 cannot build Visual Basic projects at all.
Summary
This article has demonstrated how to consume Visual Basic code in Xamarin applications using Visual Studio and .NET Standard libraries. Even though Xamarin does not support Visual Basic directly, compiling Visual Basic into a .NET Standard library allows code written with Visual Basic to be included in iOS and Android apps.
