In VBA, an assignment of variables of type Object is a shallow copy, an assignment for all other types (numeric types, String, user defined types, arrays) is a deep copy. So the keyword Set for an assignment signals a shallow copy and the (optional) keyword Let signals a deep copy. There is no built-in method for deep copies of Objects in VBA.
This documentation can be examined from inside the VBA development environment using its Object Browser. Visual Basic for Applications programs which are written to use the OLE Automation interface of one application cannot be used to automate a different application, even if that application hosts the Visual Basic runtime, because the OLE ...
Similarly the type checking functions return a Boolean recording whether the argument expression is of a particular type. In Transact-SQL, the functions return zero or one rather than Boolean values True and False. IsArray(name) This function determines whether the variable name passed as its argument is an array.
In languages compiling down to .NET platform, types are strict. Whilst the runtime allows for anonymous object which don't have a pre-defined, named type, the type of a variable may not change over the course of its life-time, hence the need to drop the Variant data-type. However, type "Object" has somewhat similar behavior in practice.
Of particular interest, however, is that Microsoft has announced the next version of Office will return Visual Basic for Applications (VBA) to the Mac platform.
In the context of Visual Basic and Ada, Sub, short for subroutine or subprocedure, is the name of a callable that does not return a value whereas a Function does return a value Object-oriented languages such as C# and Java use the term method to refer to a member function of an object
4 The object type set to a null reference. 5 TypeName will return the name of the class of the object contained. The data would be an interface pointer, that is, a pointer to a pointer to a virtual method table (which is an array of function pointers).
Visual Basic (VB) before .NET, sometimes referred to as Classic Visual Basic, [1] [2] is a third-generation programming language, based on BASIC, and an integrated development environment (IDE), from Microsoft for Windows known for supporting rapid application development (RAD) of graphical user interface (GUI) applications, event-driven programming and both consumption and development of ...
