Code written in VBA is compiled [6] to Microsoft P-Code (pseudo-code), a proprietary intermediate language, which the host applications (Access, Excel, Word, Outlook, and PowerPoint) store as a separate stream in COM Structured Storage files (e.g., .doc or .xls) independent of the document streams.
This issue makes the IIf() call less useful than the conditional operator. To solve this issue, Microsoft developers had considered [ 2 ] converting IIf to an intrinsic function; had this happened, the compiler would have been able to perform type inference and short-circuiting by replacing the function call with inline code.
This was not only inefficient, but could lead to unexpected results for any person used to another language. In Visual Basic .NET, the new AndAlso and OrElse [1] operators have been added to provide short-circuit evaluation like many other languages.
It also introduced the ability to write non-GUI classes in Visual Basic. With VB4 the language was separated from the GUI library, and made available as VBA, in which form it was embedded with the Office 95 suite. To ease migration of Office macros and scripts, features from WordBasic, Excel Basic and Access Basic were incorporated into the ...
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
arithmetic operators, such as +, -, *, /, and others; relational operators, such as >=, <, and others; and, functions, such as SUM(), TAN(), and many others. When a cell contains a formula, it often contains references to other cells. Such a cell reference is a type of variable. Its value is the value of the referenced cell or some derivation ...
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
Macros can be attached to a menu, button a keyboard shortcut or an event in the application like the opening of the document. Also user-defined functions for excel-worksheets can be provided. Security Issues VBA is designed without any security features in the language, like for example the sandbox that java appletts run in. Any function of the ...
